Description

Signal receiving device

This application relates to the field of wireless signal technology, and specifically to a signal receiving device.

Satellite signal receivers are electronic devices used to receive satellite signals. Since satellite signals come from all directions, the orientation and angle of the satellite signal receiver have a great impact on the strength of the received signal. In order to better obtain signals, the current signal receiving device generally includes two sets of drive mechanisms and mounting parts for fixing the signal receiving parts. One set of drive mechanisms is used to drive the mounting parts to rotate to adjust the orientation of the mounting parts, and the other set of drive mechanisms is used to drive the mounting parts to flip to adjust the elevation angle of the mounting parts. However, when adjusting the mounting parts, the two sets of drive mechanisms need to switch controls multiple times, which is cumbersome, resulting in high adjustment costs and low adjustment efficiency of the mounting parts.

In view of the above, it is necessary to provide a signal receiving device to simplify control, reduce regulation cost and improve regulation efficiency.

Implementation Example 1

Please refer to Figures 1 and 2 together. The present application embodiment provides a signal receiving device 10, including a base 11, a rotating assembly 12, a fixing member 13, an adjustment assembly 14 and a mounting member 15, which is used to adjust the orientation and elevation angle of the mounting member 15.

Please refer to Figure 2. In some embodiments, an umbrella-shaped gear 11a is provided at one end of the base 11. The rotating assembly 12 includes a rotating member 121 and a driving gear 122. The rotating member 121 is rotatably connected to the base 11. The driving gear 122 is rotatably connected to the rotating member 121 and engages with the umbrella-shaped gear 11a. The fixing member 13 is connected to the base 11 and is used to fix the rotating member 121. The adjustment assembly 14 includes a rotating body 141, a gear assembly (not shown) and a transmission shaft 142. One end of the transmission shaft 142 is connected to the rotating assembly 12, and the other end of the transmission shaft 142 is connected to the gear assembly. The rotating body 141 is connected to the gear assembly, and the force of the rotating body 141 driving the transmission shaft 142 to rotate through the gear assembly is smaller than the fixing force formed by the rotating member 121 and the gear assembly when the fixing member 13 fixes the rotating member 121. The mounting member 15 is connected to the rotating body 141 and is used to install the signal receiving member. When the fixing member 13 is separated from the rotating member 121, the rotating body 141 drives the gear assembly to rotate, so that the drive shaft 142 drives the active gear 122 to rotate along the umbrella-shaped gear 11a, thereby driving the mounting member 15 to rotate relative to the base 11. When the fixing member 13 fixes the rotating member 121, the fixing force formed by the drive shaft 142 and the gear assembly causes the rotating body 141 to rotate, thereby driving the mounting member 15 to flip relative to the base 11.

Specifically, the central axis of rotation of the mounting member 15 is perpendicular to the central axis of flipping of the mounting member 15. The mounting member 15 and the signal receiving member can be provided as a whole or separately. The signal receiving member can receive wireless signals, especially low-orbit satellite signals.

In the above-mentioned signal receiving device 10, when the fixing member 13 is separated from the rotating member 121, the rotating body 141 drives the gear assembly to rotate, so that the transmission shaft 142 drives the active gear 122 to rotate along the umbrella-shaped gear 11a, thereby driving the rotating body 141 and the mounting member 15 to rotate relative to the base 11, so as to adjust the orientation of the mounting member 15. When the fixing member 13 fixes the rotating member 121, the fixing force formed by the transmission shaft 142 and the gear assembly causes the rotating body 141 to rotate, so as to drive the mounting member 15 to flip relative to the base 11, so as to adjust the elevation angle of the mounting member 15. Therefore, in the above-mentioned signal receiving device 10, the rotating body 141 and the transmission shaft 142 in the adjustment assembly 14 form a mutually rotating structure through the gear assembly, which can serve as a common driving mechanism for the rotation and flipping of the mounting member 15, and cooperate with the fixing member 13 to realize the rotation and flipping of the mounting member 15 to adjust the direction and elevation angle of the signal receiving member. The operation is simple, the operation process is simplified, and the adjustment cost is reduced and the adjustment efficiency is improved.

It should be noted that the rotating body 141 and the transmission shaft 142 form a mutually rotating structure through a gear assembly, and the driving force of the mutual rotation of the two can be generated by magnetic induction. This part of the structure can be obtained by the previous technology, and this embodiment will not be described in detail.

Please refer to FIG. 2 and FIG. 3 together. In some embodiments, the rotating member 121 includes a rotating body 1211 and a connecting body 1212. One end of the rotating body 1211 is rotatably connected to the base 11, and the connecting body 1212 is vertically connected to the other end of the rotating body 1211, and one end of the connecting body 1212 is rotatably connected to the active gear 122. Therefore, the rotating member 121 forms a T-shaped structure, which can reduce the space occupied in a single direction.

In this embodiment, the driving gear 122 includes a driving wheel body 1221 and a first bearing 1222. The first bearing 1222 is sleeved on one end of the connecting body 1212, and the driving wheel body 1221 is sleeved on the first bearing 1222. The structure is simple and the manufacturing cost is low, which facilitates the replacement and disassembly of the driving gear 122 and the rotating member 121.

In some embodiments, one end of the drive shaft 142 is connected to the driving wheel body 1221 of the driving gear 122, and the mounting member 15 includes a mounting plate 151 and a locking plate 152. The mounting plate 151 is used to mount the signal receiving member, and the locking plate 152 connects the rotating body 141 and the mounting plate 151.

During operation, the rotating body 141 drives the dimension assembly to rotate, so that the gear assembly drives the drive shaft 142 to rotate, and then the drive shaft 142 drives the active wheel body 1221 of the active gear 122 to rotate along the umbrella-shaped gear 11a. During this process, the first bearing 1222 and the rotating member 121 rotate relative to the base 11 along with the active wheel body 1221.

Please refer to Figures 1 and 2 together. In some embodiments, the mounting member 15 further includes a supporting plate 153. The supporting plate 153 and the locking plate 152 are respectively located on opposite sides of the connecting body 1212, and one end of the supporting plate 153 is connected to the mounting plate 151, and the other end of the supporting plate 153 is rotatably connected to an end of the connecting body 1212 away from the rotating body 141. The cross section of one end of the driving shaft 142 is polygonal, and a slot 122a is provided on the surface of the driving gear 122 away from the connecting body 1212, and the slot 122a is adapted to one end of the driving shaft 142.

Specifically, the card slot 122a is opened at one end of the active wheel body 1221 away from the connecting body 1212, and the active wheel body 1221 is opened with a mounting slot 1221a for accommodating the first bearing 1222. The card slot 122a and the mounting slot 1221a are respectively located on opposite sides of the active wheel body 1221.

Therefore, the drive shaft 142 cooperates with the slot 122a of the active gear 122, so that the rotating assembly 12 and the adjusting assembly 14 are detachably connected, which is convenient for the disassembly of the rotating assembly 12 and the adjusting assembly 14. The rotational connection of the support plate 153 and the connecting body 1212 away from one end of the rotating body 141 can fix the mounting part 15 and prevent the mounting part 15 from being separated from the drive shaft 142 due to the drive shaft 142 being separated from the slot 122a during operation.

Please refer to FIG. 2 and FIG. 3 together. In some embodiments, the rotating assembly 12 further includes a driven gear 123. The driven gear 123 rotates the connecting body 1212 away from one end of the rotating body 141 and engages with the umbrella-shaped gear 11a. Therefore, the driven gear 123 and the driving gear 122 can make the rotating member 121 and the umbrella-shaped gear 11a of the base 11 form two-point contact, thereby improving the stability of the rotating member 121 rotating along the umbrella-shaped gear 11a. Please refer to Figure 3. In this embodiment, the driven gear 123 includes a driven wheel body 1231 and a second bearing 1232. The second bearing 1232 is sleeved on the end of the connecting body 1212 away from the rotating body 141. The driven wheel body 1231 is sleeved on the second bearing 1232. The structure is simple and the manufacturing cost is low, which facilitates the replacement and disassembly of the driven gear 123 and the rotating member 121.

In some embodiments, the base 11 is provided with a receiving groove 11b, and the rotating body 1211 includes a rotating rod 1211a and a rotating bearing 1211b. The rotating bearing 1211b is sleeved on one end of the rotating rod 1211a and received in the receiving groove 11b, and the other end of the rotating rod 1211a is vertically connected to the connecting body 1212, so that the rotating connection structure between the rotating member 121 and the base 11 is simple, and the rotating bearing 1211b is received in the receiving groove 11b, which can improve the stability of the rotation of the rotating bearing 1211b on the one hand, and avoid the collision of the rotating bearing 1211b with external components on the other hand, thereby improving the service life of the rotating bearing 1211b.

In some embodiments, the base 11 further has a rotating through hole 11c and a receiving groove 11d. The rotating through hole 11c is connected to the receiving groove 11b. The receiving groove 11d is connected to the rotating through hole 11c and is located on opposite sides of the rotating through hole 11c with the receiving groove 11b. One end of the rotating body 1211 passes through the rotating through hole 11c and extends to the receiving groove 11d. The fixing member 13 is located in the receiving groove 11d and is used to fix the rotating body 1211.

Therefore, the accommodating groove 11b, the rotating through hole 11c and the receiving groove 11d can reduce the weight of the base 11, making it easier to move. In addition, they can also accommodate the rotating bearing 1211b and the fixing member 13, thereby reducing the overall occupied area of the signal receiving device 10.

In this embodiment, the fixing member 13 is a brake, that is, the hollow part of the brake forms a clamping part, and the rotating body of the rotating rod 1211a is fixed by clamping. Because the brake is a prior art, it will not be explained in detail here.

Please refer to FIG. 1 and FIG. 2 together. In some embodiments, the signal receiving device 10 further includes a stopper 16. The stopper 16 is connected to the support plate 153 of the mounting member 15, and is used to fix the connecting body 1212 when the fixing member 13 is separated from the rotating rod 1211a of the rotating member 121, so that the connecting body 1212 forms a fixing effect on the stopper 16, thereby preventing the rotating body 141 from shaking at a small angle when the driving shaft 142 rotates relative to the rotating body 141, which causes the elevation angle of the mounting member 15 to change, thereby improving the accuracy of the adjustment of the mounting member 15.

In this embodiment, the limiter 16 is a brake, that is, the hollow part of the brake forms a clamping part, and the connecting body 1212 of the rotating member 121 is fixed by clamping. Because the brake is an existing technology, it will not be explained in detail here.

Here, the electromagnetic force is used as an example to form the driving force for the rotation of the rotating body 141 and the transmission shaft 142, and the working process of the above-mentioned signal receiving device 10 is explained: the rotation process of the mounting member 15: first, the signal receiving member is mounted on the mounting plate 151, and the fixing member 13 is separated from the rotating member 121, and the limiting member 16 fixes the connecting body 1212, and then, the rotating body 1 is powered. 41 or the transmission shaft 142, so that an electromagnetic force is formed between the rotating body 141 and the transmission shaft 142, and the electromagnetic force drives the transmission shaft 142 to drive the active wheel body 1221 of the active gear 122 and the driven wheel body 1231 of the driven gear 123 to rotate along the umbrella-shaped gear 11a, thereby driving the rotating body 141 and the mounting member 15 to rotate relative to the base 11.

The flipping process of the mounting member 15: First, install the signal receiving member on the mounting plate 151, and make the fixing member 13 fix the rotating member 121, and the limit member 16 separate from the connecting body 1212. Then, power is supplied to the rotating body 141 or the transmission shaft 142, so that an electromagnetic force is formed between the rotating body 141 and the transmission shaft 142. Since the electromagnetic force formed is smaller than the fixing force formed by the rotating member 121 and the gear assembly, the electromagnetic force formed drives the rotating body 141 to rotate, thereby driving the mounting member 15 connected to the rotating body 141 to flip.

This embodiment is similar to the first embodiment, both of which include a base 11, a rotating assembly 12, a fixing member 13, an adjusting assembly 14 and a mounting member 15. The difference is that in this embodiment, the fixing member 13 is arranged in the area surrounded by the umbrella-shaped gear 11a, and is used to clamp the connecting body 1212 of the rotating member 121 to fix the rotating member 121.

Specifically, the fixing member 13 includes a clamping driving body 13a and a pair of clamping parts 13b. The clamping driving body 13a is connected to the base 11 and is used to drive the pair of clamping parts 13b to rise and approach each other. When fixing the rotating member 121, the clamping driving body 13a first drives the pair of clamping parts 13b to rise so that the pair of clamping parts 13b are respectively located at the opposite sides of the connecting body 1212, and then the clamping driving body 13a drives the pair of clamping parts 13b to approach each other to clamp the opposite sides of the connecting body 1212. Among them, the structure of the fixing member 13 in this embodiment can also be applied to the first embodiment. For example, the clamping drive body 13a may be a composite structure of a lifting cylinder and a linear cylinder.

For example, the fixed driving body 131 can be a cylinder.

In this embodiment, the fixing member 13 is received in the receiving groove 11d, and the fixed driving body 131 is connected to the side wall of the receiving groove 11d.

During operation, the fixed driving body 131 drives the fixed rod 132 to insert into the fixed groove 1211c, thereby achieving the braking of the rotating member 121. When the rotating member 121 needs to rotate, the fixed driving body 131 drives the fixed rod 132 to disengage from the fixed groove 1211c.

Compared with the first embodiment, the braking method of the rotating member 121 of the present embodiment is different. The fixing rod 132 is matched with the fixing groove 1211c, which is simple to manufacture and low in cost.
