Description

breaking device

The present invention relates to a breaking device, in particular to a breaking device not triggered by a hook structure.

In recent years, with the rapid development of the electronics industry, information products have been continuously introduced. Mobile devices and computer products are inseparable from our lives, allowing users to obtain the information they need anytime, anywhere in their daily lives. Generally, the data storage devices in electronic devices such as mobile devices, computers or tablet computers include different types of memory cards, hard drives, flash drives or sensor chips, etc., for data storage and data transmission, but if you encounter other Users or those who are interested in deliberately dismantling or destroying the machine can easily steal the internal information of the machine. In view of this, a mechanism for solving the security and confidentiality protection of electronic devices was born.

One of the more common types of safety protection mechanisms in the industry is a breaking device with a hook structure designed on the casing of the device as a trigger mechanism, thereby protecting the internal information of the machine from being stolen by malicious people. Taking the induction chip as an example, the trigger mechanism is stopped by the stopper, and the hook on the casing is closely combined with the hook of the stopper. It will be removed together with the hook structure. At this time, the breaking device is triggered to destroy the sensing chip. Whether the electronic device is damaged and whether the internal data is stolen can be judged by whether the data of the chip can be read.

However, the breaking device designed with a hook structure on the casing as a trigger mechanism has the following disadvantages:

First, not all casing materials and structural parts are suitable for hook design. For example, non-elastic materials are not suitable, because they are easy to break and difficult to assemble, which will also lead to problems such as inability to disassemble. If elastic hooks are required If it is not, then the opponent will add another plastic part as a component, increasing the overall cost.

Second, a large space for structural design is required: when the hook is combined and disassembled, elastic deformation must occur. With elastic deformation, the hook can be combined and disassembled smoothly. Therefore, it must be prepared in advance inside and outside the machine. Leave the space required for elastic deformation, so that the volume of the whole machine becomes larger.

Third, when the hook structure is blindly assembled, it is easy to cause functional failure: when the upper and lower casings are assembled, because the hook structure is located in the internal closed space, it is impossible to confirm whether the hook is indeed engaged in place, nor can it be confirmed Check whether the hook is broken. If this happens, when the casing is disassembled and separated, the breaking device will not be triggered, resulting in functional failure.

In view of the above disadvantages, the purpose of the present invention is to provide a breaking device triggered by a non-catch structure, which has the function of quickly judging whether the machine has been deliberately disassembled and then reassembled, and can avoid the traditional hook structure being limited by materials and requiring pre-installation.

Figure 2A to Figure 2C are schematic diagrams of the action process of the breaking device in Figure 1C entering the pre-firing state; Figure 3A to Figure 3C are schematic diagrams of the process of assembling the breaking device and machine in Figure 1C; and Figure 4A and Figure 4B are the breaking device and machine Schematic diagram of the actuation process of the breaking device when the table is separated. In order to clearly illustrate the actuation process, FIG. 2A to FIG. 4C are cross-sectional views respectively.

Please refer to Fig. 1A to Fig. 1C again, you can first install the striker 121, the striker holder 122, the first spring member 123, the limiter 131, the trigger member 132, the second elastic member 133, the connecting rod 134, the slider 135, the two The connecting rod cover 136 , the trigger seat 141 , and the third elastic member 142 are assembled at corresponding positions of the lower casing 111 . Next, the upper casing 112 is locked to the lower casing 111 with screws S to obtain the breaking device 1 of this embodiment.

Afterwards, please refer to FIG. 2A to FIG. 2C , move the striker fixing seat 122 protruding from the handle of the housing 11 (the handle can refer to FIG. 1A ) to move in the direction D1 (ie, the left side of FIG. 2A ), and the striker fixing seat 122 The flange portion 1221 of the stopper 131 will be in contact with the flange portion 1331 of the stopper 131 (at position A in FIG. 2B ); when the striker holder 122 continues to move along the direction D1, the stopper 131 will be fixed with the column O1 In order to rotate the pivot to perform counterclockwise rotation, at this time, the second protrusion C2 of the stopper 131 will rotate to contact with the mating surface 1321 of the trigger member 132 (position B in FIG. 2B ), along with the striker fixing seat 122 The action in the direction D1 continues, and the limiter 131 will move the trigger 132 to rotate clockwise with the fixed column O2 as the rotation pivot; when the limiter 131 rotates to the horizontal (Fig. Pulled by the elastic force of the second elastic member 133, the second convex portion C2 of the limiting member 131 and the second concave portion U2 of the trigger member 132 will be engaged and fixed (position C in FIG. 2C ), and the limiting member The first convex portion C1 of 131 will be embedded in the first concave portion U1 of the striker fixing seat 122 (at position D in FIG. 2C ), so as to fix the stopper 131 at the position of clamping the breaking unit 12 through the trigger member 132. At the same time, the first The elastic member 123 is compressed, and at this time, the restraining and limiting action of the firing pin holder 122 is completed to reach the pre-firing state (the limiting member 131 and the trigger member 132 of the limiting unit 13 restrain the movement of the breaking unit 12). Afterwards, the wafer holder 30 is attached to the housing 11 ( FIG. 1A ), so that the striker 121 corresponds to the position of the target part 3 .

Next, as shown in FIG. 3A , the cracking device 1 is fixed in the machine (for example, connected to the mounting part 4 inside the electronic device), and the casing lower cover 2 and the mounting part 4 are assembled together. When the casing lower cover 2 is assembled downwards (direction D2) on the installation part 4, as shown in Figure 3B, the stop structure 21 (ejection rib) will first touch the slope 1412 of the trigger seat 141 of the breaking device 1 . As the case lower cover 2 continues to move in the direction D2, as shown in Figure 3B and Figure 3C, under the interaction between the inclined surface 211 of the stop structure 21 and the inclined surface 1412 of the trigger seat 141, the trigger seat 141 will move in the direction D2. D1 moves in the opposite direction (the right side of FIG. 3C ), and the third elastic member 142 will be pressed by the trigger seat 141 to generate elastic force. At the same time, the elastic arm hooking part 1411 of the trigger seat 141 will be elastic downward. The deformation passes over the third convex portion C3 of the slider 135 and resets to fit (fasten) into the third concave portion U3 of the slider 135 . Specifically, as shown in FIG. 3B , the elastic arm hooking portion 1411 includes a first installation slope S1, and the slider 135 includes a second installation slope S2 corresponding to the first installation slope S1 (the two slopes face each other). When the trigger base 141 moves in the direction opposite to the direction D1 (the right side of FIG. 3B ), the first installation slope S1 will push against the second installation slope S2, and the elastic arm hook portion 1411 will pass over the first installation slope of the slider 135 due to elastic deformation. After the three convex parts C3 are reset, the elastic arm hooking part 1411 is engaged with the third concave part U3 of the slider 135 again. When the stop structure 21 completely stops the trigger seat 141, the elastic arm hooking portion 1411 of the trigger seat 141 will snap into the third recess U3 of the slider 135, thereby clamping the movement of the trigger seat 141 (FIG. 3C ), and at the same time, the trigger seat 141 will also compress the third elastic member 142 to generate elastic force, so as to provide the force for the trigger seat 141 to move toward the stop structure 21 . Therefore, when the casing lower cover 2 and the mounting member 4 are assembled, the trigger base 141 will be limited by the stop structure 21 , so that the trigger base 141 cannot move in the direction D1.

Please refer to FIGS. 4A and 4B , when someone removes the casing upwards, the bottom cover 2 of the casing and the stopper structure 21 will continue to move upward (the upper side of FIG. 4A ). When the stop structure 21 is completely separated from the trigger seat 141, the elastic force generated by the compression of the third elastic member 142 will push the trigger seat 141 to move in the direction D1 and move the sliding block 135 and the connecting rod 134, thereby driving the trigger Member 132 rotates. In detail, when the stopper structure 21 moves upward (that is, the direction opposite to the direction D2) and completely deviates from the lateral actuation stroke of the trigger seat 141, the trigger seat 141 will move in the direction D1 due to the release of the elastic force of the third elastic member 142. At this time, the trigger seat 141 will drive the slider 135 and the connecting rod 134 to move in the direction D1 through the elastic arm hooking part 1411 and the third concave part U3, and simultaneously pull the trigger 132 clockwise around the fixed column O2. Rotate (direction D3) to release the clamping of the limiter 131, so that the limiter 131 is no longer fixed at the position of clamping the breaking unit 12, at this time the elastic force of the first elastic member 123 can be released and push the striker fixing seat 122 And the firing pin 121 moves rapidly in the direction of the target piece 3 (the opposite direction of the direction D1) to fire (the trigger seat body 141 is opposite to the moving direction of the firing pin 121), and then the target piece 3 (wafer) is indeed destroyed to make it invalid. At the same time, the stopper 131 also rotates clockwise around the fixed column O1 because the striker fixing seat 122 moves in the opposite direction to the direction D1, so that the first convex part C1 of the stopper 131 is completely disengaged from the striker fixing seat 122. The first recess U1.

To sum up, in the crushing device of the present invention, the crushing unit is movably arranged on the casing and is arranged corresponding to the target; the limiting unit is movably arranged on the casing and is suitable for clamping the movement of the crushing unit The trigger unit is movably arranged on the housing and connected to the restriction unit, and the stop structure is suitable for blocking the movement of the trigger unit; wherein, when the stop structure is separated from the trigger unit, the trigger unit moves and the linkage restriction unit releases the pair When the crushing unit is clamped, the structural design of the crushing unit can move towards the target and hit the target, so that the crushing device of the present invention is a crushing device that is not triggered by a hook structure, and has the ability to quickly judge whether the machine is deliberately disassembled and then reinstalled. Reassembled functions. Therefore, the breaking device of the present invention does not have the disadvantages of the prior art that uses the hook structure as the trigger mechanism, which is limited by material, needs to reserve a deformation space for the hook, and is prone to functional failure.
