Description

{REAR GLASS OPENING DEVICE OF PICKUP TRUCK}

The present invention relates to a rear glass opening/closing device for a pickup truck, and more specifically, to a rear glass opening/closing device for a pickup truck that opens/closes a rear glass installed at the rear of an interior space of a pickup truck.

Pickup trucks, unlike regular sedans or SUVs, have a separate cargo bed, so they have excellent loading capacity, and they have excellent off-road driving and towing capabilities, so they are chosen by consumers who often transport items or enjoy camping and leisure activities that involve frequent off-road driving.

Also, for the same reason, it is widely used by those in agriculture, livestock, and construction.

In this way, pickup truck users are making the most of the pickup truck's cargo space by loading and transporting items of various sizes and weights.

However, conventional pickup trucks, like the vehicle disclosed in Patent Document 1 below, have a structure in which the interior space of the vehicle and the loading space are completely separated. That is, there was a problem in that the loading capacity of conventional pickup trucks was limited to the loading space.

For example, it is not easy to load items such as wood or pipes that are longer than the loading box. Of course, you can force them to load, but in this case, the rear end of the items will protrude outside the loading box, making it impossible to close the tailgate, which can cause safety issues.

In addition, conventional pickup trucks required access from the side or rear of the cargo bed to remove items loaded in the cargo bed. In other words, items stored in the cargo bed had to be removed only by accessing them from the outside of the vehicle, which limited accessibility to the cargo bed.

Accordingly, a connecting passage was formed between the indoor space and the loading compartment, an openable center gate was installed in approximately the lower half of the connecting passage, and a rear glass was installed in the space above the center gate.

Accordingly, by opening the center gate, long objects can be loaded, and by approaching the loading compartment from the indoor space, materials or tools stored in the loading compartment can be taken out and used.

However, in order to maximize the effect of the center gate, it is advantageous for the connecting passage to be completely open, and accordingly, the rear glass needs to be opened and closed, and thus the need for a rear glass opening and closing device for a pickup truck was raised.

The prior art is technical information that the inventor possessed for the purpose of deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be a publicly known technology disclosed to the general public prior to the application for the present invention.

Referring to FIGS. 1 to 8, a rear glass opening/closing device of a pickup truck according to an embodiment of the present invention includes a rear glass (20), a roof (30), and a rear glass driving device (40).

The above rear glass (20) is configured to be installed in the upper part of the connecting passage (5) formed between the interior space and the loading compartment of a pickup truck.

The above connecting passage (5) is formed by penetrating the rear wall of the body forming the interior space of the pickup truck.

An openable center gate (10) is installed in the lower part of the above connecting passage (5). The center gate (10) rotates toward the indoor space to open the lower part of the connecting passage (5), that is, the space below the rear glass (20).

The above rear glass (20) serves to block the space between the upper part of the center gate (10) and the lower part of the roof (30) among the cross-sectional areas of the above connecting passage (5).

The above rear glass (20) can be operated by the rear glass driving device (40) to be inserted and stored inside the loop (30), thereby opening the upper portion of the connecting passage (5).

Accordingly, when both the center gate (10) and the rear glass (20) are opened, the connecting passage (5) is completely opened, so there is no obstacle that hinders movement between the indoor space and the loading box.

Accordingly, accessibility from the indoor space to the loading compartment is improved, and accessibility from the loading compartment to the indoor space is also improved. In other words, bidirectional accessibility (and mobility) between the indoor space and the loading compartment is improved.

In addition, since it is possible to load items exceeding the length of the loading box, the loading performance and loading efficiency are improved.

The above loop (30) is configured to form a storage space for the rear glass (20).

Additionally, the above loop (30) forms an installation space for the rear glass driving device (40).

The above loop (30) can be configured to be detachable from the side body of the vehicle.

The above loop (30) is manufactured in a rectangular box shape having a predetermined thickness (a thickness that allows storage of the rear glass (20) and installation of the rear glass driving device (40).

In addition, the roof (30) is installed with the rear glass driving device (40) inside with the top plate (cover) removed. The roof (30) can be manufactured separately as a module equipped with the rear glass driving device (40) and then mounted on a vehicle, and can be detached as needed.

In addition, the loop (30) has an entry/exit hole (31) formed on the rear side of the bottom surface through which the rear glass (20) enters/exits.

The above access hole (31) has a length (horizontal length) longer than the width of the rear glass (20) so that the rear glass (20) can pass through, and is formed long in the transverse direction of the loop (30). In addition, the access hole (31) has a sufficient front-back direction length (vertical length) so that interference does not occur between the front-back and rear-end ends of the access hole (31) when the rear glass (20) rotates and moves inwardly of the loop (30).

The above rear glass driving device (40) is installed inside the loop (30) and is configured to pull the rear glass (20) toward the inside of the loop (30) or return it to the upper part of the connecting passage (5).

The above rear glass driving device (40) includes a frame (41) installed on the inside of the loop (30) and having a guide hole (41b) formed in a side wall portion (41a), an electric cylinder (42) rotatably installed on the rear wall of the loop (30), a connecting rod (43) rotatably connected to a cylinder rod (42a) of the electric cylinder (42), and a slider (44) fixed to the upper end of the rear glass (20), installed so as to be movable along the guide hole (41b), and rotatably connected to the connecting rod (43).

The above frame (41) is a rectangular structure that can be installed inside the above loop (30) and is sized to accommodate the rear glass (20). The frame (41) has a front wall portion and a side wall portion (41a) formed vertically at the front and both sides of the rectangular floor member, respectively. The side wall portion (41a) has a guide hole (41b) formed in a straight line along the length direction of the side wall portion (41a). The floor member can be manufactured as a lattice structure in which a number of through holes are formed to reduce weight.

The above electric cylinder (42) is also referred to as a linear actuator and provides a driving force to pull the rear glass (20) toward the inside of the roof (30) or return it to its initial position.

The above electric cylinder (42) includes a motor, a reduction gear, and a cylinder rod (42a) that moves linearly by a spiral structure. The electric cylinder (42) is rotatably installed on a bracket (32) fixed to the rear wall of the loop (30) at a base end (an end opposite to the portion from which the cylinder rod (42a) protrudes), and an end of the cylinder rod (42a) is rotatably connected to the upper surface of the connecting rod (43).

In this specification, the term 'rotatably connected' means that the two parts to be connected are connected via a connecting part having a circular shaft shape, such as a pin or bolt, so that the two parts can rotate relative to each other around the connection point.

The above connecting rod (43) is configured to connect the electric cylinder (42) and the slider (44). One end of the connecting rod (43) is rotatably connected to the lower end of the end of the cylinder rod (42a), and the other end is rotatably connected to the slider (44).

At the other end of the above connecting rod (43), a straight slot (43a) is formed that extends in the length direction of the above connecting rod (43), and the slider (44) is connected to this slot (43a) via a pin (44b).

The above slider (44) has a pair of pin installation portions (44a) formed on both sides of the upper surface of the body portion fixed to the rear glass (20), and the pin (44b) is installed through the pin installation portions (44a). The pin (44b) passes through the slot (43a) formed at the rear end of the connecting rod (43).

The body portion of the above slider (44) is formed in a shape that surrounds the upper portion of the rear glass (20). The body portion may be fixed to the upper portion of the rear glass (20) using a joining part such as a rivet or bolt, or may be fixed using an adhesive, fusion, or other method.

The above slider (44) can be mounted on the upper protection material (21) installed on the upper part of the rear glass (20) of the body part.

The upper protective material (21) may be made of metal or plastic, and wraps around and protects the entire upper portion of the rear glass (20). The upper protective material (21) is fixed to the upper portion of the rear glass (20) with an adhesive.

When the above upper protection material (21) is installed, the slider (44) is mounted on the outer surface of the above upper protection material (21).

Since the pin (44b) is inserted into the slot (43a) of the connecting rod (43), the connecting rod (43) and the slider (44) can rotate and move linearly with respect to each other. Accordingly, the connecting rod (43) and the slider (44) can maintain a connected state with each other while the position of the connecting point can be changed, so that when the rear glass (20) is operated by the electric cylinder (42), the rotation and linear movement can be performed more smoothly.

In addition, the slider (44) has a first roller (44c) installed on one end of the pin (44b), and the first roller (44c) moves along the guide hole (41b).

The above pin (44b) not only connects the connecting rod (43) and the slider (44) so that they can rotate and move linearly, but also provides an installation location for the first roller (44c).

The above pin (44b) extends into the inside of the guide hole (41b), and the first roller (44c) is installed at the end of the pin (44b), so that the first roller (44c) can roll and move on the upper surface of the guide hole (41b).

Since the movement of the slider (44) is enabled with less force by the first roller (44c), the electric cylinder (42) can more easily pull the rear glass (20) toward the inside of the loop (30).

Meanwhile, the rear glass driving device (40) further includes a rotation guide (45) that guides rotation and linear movement of the rear glass (20) when the rear glass (20) is opened and closed.

The above rotation guide (45) is rotatably installed on the side of the entrance hole (31) of the rear glass (20) formed in the loop (30) among the side wall portions (41a) of the frame (41), and a plurality of second rollers (45a) are installed on the side to support both sides of the side end portion of the rear glass (20).

The above rotation guide (45) has a disc shape, but is not necessarily limited thereto. The rotation guide (45) may only have two second rollers (45a) installed on the side. In this case, the side end of the rear glass (20) is supported by one second roller (45a) on each side. The embodiment illustrated in FIGS. 3 and 4 illustrates a state in which a total of four second rollers (45a) are installed on the side of the rotation guide (45). In this case, the side end of the rear glass (20) is supported by two second rollers (45a) on each side, so the stability of support and operation is improved.

At this time, the rear glass (20) is provided with a side protection member (22) installed on the side edge, and the side protection member (22) is inserted and supported between the second rollers (45a) of the rotation guide (45). That is, the side protection member (22) is installed in a structure that surrounds the side edge of the rear glass (20) and can be fixed with an adhesive. Since the second roller (45a) does not directly contact the surface of the rear glass (20) due to the side protection member (22), damage to the side edge of the rear glass (20) is prevented.

The operation switch (not shown) of the above rear glass driving device (40) is installed in the interior space. In addition, the operation switch forms a power supply circuit together with the battery and the electric cylinder (42). The operation switch supplies power to the electric cylinder (42) and is configured to select and operate the motor operation direction of the electric cylinder (42). Accordingly, a passenger can operate the operation switch in the interior space to protrude or, conversely, retract the cylinder rod (42a) of the electric cylinder (42).

In the closed state of the rear glass (20) as in Fig. 1, when the cylinder rod (42a) of the electric cylinder (42) protrudes, the connecting rod (43) moves forward of the loop (30) in conjunction with the cylinder rod (42a), and accordingly, the slider (44) connected to the connecting rod (43) moves forward of the loop (30). This operation continues through the state of Fig. 7 until the point where the cylinder rod (42a) is fully extended as in the state of Fig. 8. At this time, the electric cylinder (42) rotates around the connection point with the bracket (32). As the protrusion amount of the cylinder rod (42a) increases, the angle of the electric cylinder (42) with respect to the rear wall of the loop (30) increases.

When the electric cylinder (42) is operated as described above, the slider (44) moves forward of the loop (30) along the guide hole (41b), and thus the rear glass (20) fixed to the slider (44) also moves forward of the loop (30).

At this time, as the amount of movement toward the inside of the loop (30) increases, the rear glass (20) gradually rotates from a vertical state to a horizontal state. At this time, the rotation guide (45) simultaneously allows rotation and linear movement of the rear glass (20) while supporting the rear glass (20), so that the rear glass (20) can smoothly move toward the inside of the loop (30) and be stored. The operation process is carried out in the order of FIGS. 1, 5, and 6, and the operation in which the rear glass (20) moves from the inside to the outside of the loop (30) and returns to a closed state is carried out in the reverse order.

As described above, since the rear glass (20) can be opened and closed, the vehicle can be used with the rear glass (20) open when necessary. That is, when the rear glass (20) is opened, it can help to quickly ventilate the interior space and increase the feeling of openness, just like a general window glass.

In addition, the rear glass (20) is completely stored inside the loop (30) when the connecting passage (5) is opened and used, so that it does not interfere with or collide with loaded goods or passengers while moving through the connecting passage (5), and thus movement of goods and passengers can be made easier and safer, and damage to goods and the rear glass (20) is prevented.

In addition, when the rear glass (20) is opened, the upper space of the connecting passage (5) between the indoor space and the loading box is opened as described above. Therefore, an object longer than the loading box can be loaded by using this open space, and an object can be moved from the indoor space to the loading box for storage or an object stored in the loading box can be taken out to the indoor space. In other words, the accessibility and usability of the loading box are increased.

This operational effect can be doubled by opening the center gate (10) installed on the lower side of the rear glass (20).

As described above, the rear glass opening/closing device of a pickup truck according to the present invention has the same operational effect as a general window glass opening, and can completely open the space between the interior space of the pickup truck and the loading compartment when operated together with the center gate, thereby improving the loading efficiency and accessibility of the loading compartment.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is merely exemplary, and it should be understood that various modifications and equivalent other embodiments are possible based on common knowledge in the field to which the technology pertains. Therefore, the true technical protection scope of the present invention is determined by the claims described below and should be determined based on the specific contents of the invention described above.

The present invention relates to a rear window opening/closing device for a pickup truck, and can be used in industrial fields related to rear window opening/closing devices for vehicles.
