[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig. 9 The present invention is further described in detail.

[0032] An embodiment of the present invention provides a final inspection test machine for an automobile glass lifter, comprising a detection device 1, wherein the detection device 1 comprises a locking mechanism 3 for fixing a test board 2 on a placement table, and a toggle mechanism 4 is provided on the locking mechanism 3; the toggle mechanism 4 comprises a substrate 40 and a plurality of toggle blocks 41 arranged on the substrate 40, wherein the number of the plurality of toggle blocks 41 is the same as the number of button switches 20 on the test board 2, and a driving mechanism connected to the detection device 1 via an electrical signal is further provided on the substrate 40; based on a detection signal of the detection device 1, the driving mechanism drives each toggle block 41 to move so as to toggle each button switch 20 on the test board 2.

[0033] Specifically, the toggling of the button switch 20 on the test board 2 is usually based on upward toggling (i.e., toggling the button switch 20 upward to give the mechanical part of the glass lifter a command to move the glass upward) and downward toggling (i.e., toggling the button switch 20 downward to give the mechanical part of the glass lifter a command to move the glass downward). For ease of description and understanding, this toggling method is also used in this embodiment.

[0034] The detection device 1 has been introduced in detail in the aforementioned background technology, and will not be described in detail here. The locking mechanism 3 in the detection device 1 is used to fix the test board 2 to be detected on the placement table. The locking mechanism 3 mainly drives the clamping plate to cooperate with the placement table through the cylinder to realize the clamping action of the test board 2. Because in the prior art, when the button switch 20 of the test board 2 is detected, the button switch 20 is manually toggled, resulting in the problem of low detection efficiency. Therefore, in this embodiment, a toggle mechanism 4 is provided to solve this problem. When the toggle mechanism 4 contacts each button switch 20 on the test board 2, the toggle mechanism 4 can be connected to the clamping plate 31. When the clamping plate 31 is driven by the clamping cylinder 32 to complete the action of clamping the test board 2, the toggle mechanism 4 is also driven to contact each button switch 20. The connection method between the clamping plate and the toggle mechanism 4 is the prior art and will not be described in detail. The number of toggle blocks 41 provided on the toggle mechanism 4 corresponds to the number of button switches 20 on the test board 2. In actual applications, generally, there are four button switches 20 on the main driver's door of a car for controlling the lifting of the glass, and one button switch 20 on the other doors for controlling the lifting of the glass. Therefore, in this embodiment, the number of button switches 20 on the main driver's door is used as a reference, and the number of toggle blocks 41 is also set to four. During use, each toggle block 41 corresponds to a button switch 20, wherein the driving mechanism can drive the four toggle blocks 41 to move respectively, and the driving mechanism is connected to the detection device 1 through an electrical signal, that is, when the detection device 1 needs to obtain the lifting function signal of the button switch 20, the driving mechanism will drive the toggle block 41 to toggle the button switch 20, wherein the driving mechanism can be a mechanism for realizing linear reciprocating motion, which is a prior art and will not be elaborated in detail.

[0035] The beneficial effect of this embodiment is that by setting the toggle mechanism 4, the button switch 20 on each test board 2 can be toggled (up and down) according to the detection signal sent by the detection device 1, so that the detection device 1 can more quickly obtain the signal of whether the lifting function of the button switch 20 is qualified, thereby effectively improving the detection efficiency of the test board 2.

[0036] The locking mechanism 3 includes a plurality of fourth rod bodies 30, which are arranged to slide on the placement table, and in the sliding direction, a fifth elastic member is provided between each fourth rod body 30 and the placement table; a clamping plate 31, which is provided on the detection equipment and driven by a clamping cylinder 32 to press the test plate; when fixing the test plate, the test plate is placed on the first rubber pad 33, and the clamping cylinder 32 drives the clamping plate 31 to press the test plate on the first rubber pad 33, and the plurality of fourth rod bodies 30 are in different heights based on the different downward pressure distances of various parts of the test plate.

[0037] Specifically, for the clamping and fixing of the test board during inspection, the test board is placed vertically downward on the placement plate as a reference, and the clamping cylinder 32 of the locking mechanism 3 drives the clamping plate 31 to cooperate with the placement table to clamp the test board. The clamping plate 31 also moves from top to bottom to clamp the surface of the test board with the button switch, but does not interfere with the toggle test of the button switch. The detection equipment is introduced in detail in the aforementioned background technology, and no further elaboration is made here.

[0038] During operation, the test board is placed on the placement table, the test board is electrically connected to the detection equipment, the clamping cylinder 32 drives the clamping plate 31 to cooperate with the placement table to fix the test board, and then by toggling the button switch, the detection equipment can obtain the lifting function signal of the button switch. In the prior art, when the button switch of the test board is tested, the clamping plate 31 is driven by the clamping cylinder 32, and then the test board is clamped and fixed in cooperation with the placement table. The clamping force of the test board mainly comes from the vertical upper and lower sides, and there is no structure around it that adapts to the shape of the test board to ensure the stability of the test board during the test process. When the button switch is toggled, a force in the horizontal direction will be applied to the test board. If the test board moves under the action of this force, it will cause a large error in the test result.

[0039] Therefore, in this embodiment, the arrangement of the plurality of fourth rod bodies 30 is to slide vertically along the placement table, and a channel is provided in the middle of the placement table so that the test board and the detection device can be electrically connected. Then, the plurality of fourth rod bodies 30 are evenly arranged around the channel and are shaped like a rectangular frame. When the plurality of fourth rod bodies 30 are pressed down by an object with an irregular shape, when the object cannot continue to move downward, the plurality of fourth rod bodies 30 move downward by different distances after being pressed downward. Then, the first rubber pad 33 is arranged at the vertical upper end of the fourth rod body 30. The coverage area of ​​the first rubber pad 33 is larger than the area of ​​the bottom of the test board, so as to ensure that when testing test boards of different specifications, the bottom of the test board and the first rubber pad 33 are both in contact with each other. There are larger parts in contact with each other. When the test plate is clamped and fixed, the test plate is first placed on the first rubber pad 33, and then the clamping cylinder 32 drives the clamping plate 31 to press the test plate downward, so that the test plate presses down on several first plug rods. The downward movement of the first plug rods will increase the elasticity of the corresponding fifth elastic members. After the clamping plate 31 can no longer move downward, it means that the test plate has moved down to the lowest position. At this time, several fourth rod bodies 30 with different downward movement distances will support the test plate in multiple positions, and the fourth rod body 30 that is not pressed by the test plate at the edge will limit the horizontal movement of the test plate, so that the test plate can be stably clamped.

[0040] Furthermore, the placement table is also provided with a correction mechanism. When the test board to be tested is placed on the first rubber pad 33, the placement position of the test board is corrected based on the correction action of the correction mechanism; the correction mechanism includes four correction plates 34 arranged around the test board to be tested, and a correction seat 35 is slidably provided on the placement table corresponding to the position of each correction plate 34, and a sixth elastic member is provided between the correction seat 35 and the placement table. Each correction plate 34 is swingably arranged on the correction seat 35 at the corresponding position, and a seventh elastic member is provided at the swinging position. In the process of placing the test board to be tested on the first rubber pad 33, the test plate is first positionally corrected with the correction plate 34; a plurality of balls 310 are rollingly arranged on the surface of the clamping plate 31 that contacts the test plate.

[0041] Specifically, in the aforementioned embodiment, the test board needs to be electrically connected to the detection equipment, that is, each button switch on the test board needs to be connected to the corresponding detection point on the detection equipment, so the position of the test board needs to be corrected. When the test board is manually placed on the first rubber pad 33, the position of the test board needs to be carefully adjusted to ensure accurate connection. Obviously, this method is time-consuming and labor-intensive for the testing operation of the test board.

[0042] Therefore, in this embodiment, a correction mechanism is provided on the placement table, so that when the test board is placed on the first rubber pad 33, there is no need to deliberately adjust the position of the test board, and the correction mechanism can adjust the position of the test board, that is, after the test board is placed on the placement table, a correction plate 34 is arranged on each of the four positions on the placement table corresponding to the alignment of the button switch and the detection device when connected, and each correction plate 34 corresponds to a correction seat 35, and the correction seat 35 is slidably arranged on the placement table, and the sliding direction is perpendicular to the sliding direction of the fourth rod body 30, and under the elastic force of the sixth elastic member, the correction seat 35 has a tendency to always drive the corresponding correction plate 34 to approach the center of the placement table, wherein when the test board to be tested is not placed on the first rubber pad 33, the correction plate 34 is inclined, and its lower end is close to the center of the placement table. When squeezed by the test board, the high end of the correction plate 34 does not swing in the direction away from the center of the placement table. When the correction plate 34 is squeezed by the test plate, the correction plate 34 will drive the corresponding correction seat 35 to move away from the center position of the placement table. Conversely, under the elastic force of the sixth elastic member, the correction plate 34 will also squeeze the test plate. The four correction plates 34 squeeze the test plate together so that the test plate can move toward the center position of the placement table. In order to reduce the friction between the clamping plate 31 and the test plate, a plurality of balls 310 are arranged on the clamping plate 31 in a rolling manner. In this way, when the test plate is squeezed by the correction plate 34, the balls 310 roll in contact with the test plate. Moreover, since the four correction plates 34 are arranged obliquely and give the test plate a tendency to move toward the center position of the placement table, the position of the test plate is corrected. After the position of the test plate is corrected, as the clamping plate 31 continues to press downward, the test plate will contact the first rubber pad 33 and press down the fourth rod 30, thereby finally achieving the clamping and fixing of the test plate.

[0043] Preferably, the base plate 40 is provided with a plurality of first elastic members, each of which is provided with a mounting plate 42, a plurality of toggle blocks 41 correspond one to one with the plurality of mounting plates 42, a plurality of mounting holes 43 are opened on the mounting plate 42, each toggle block 41 is provided with an insertion rod 44, and each insertion rod 44 can be connected to any mounting hole 43 by plugging.

[0044] Specifically, since the position of the button switch 20 equipped in different vehicle models varies, the position of each toggle block 41 needs to be adjusted accordingly. Therefore, in this embodiment, a mounting plate 42 is correspondingly provided for each toggle block 41, and each mounting plate 42 is connected to the base plate 40 through a first elastic member. Based on the elastic force of the first elastic member, when the driving mechanism does not drive a certain toggle block 41 to toggle the button switch 20, the toggle block 41 can be reset under the action of the corresponding first elastic member's rebound force, waiting to be driven by the driving mechanism next time to toggle the button switch 20. A number of mounting holes 43 are provided on each mounting plate 42, and each toggle block 41 can be plugged into any mounting hole 43 on the corresponding mounting plate 42 through an insertion rod 44. In this way, the position of each toggle block 41 can be adjusted accordingly according to the position change of the button switch 20 on the test board 2, so as to adapt to more vehicle models.

[0045] Preferably, the driving mechanism drives the toggle block 41 to toggle the button switch 20, which includes a first time period and a second time period, and the first time period is shorter than the second time period.

[0046] Specifically, during the process of raising and lowering the vehicle window, by toggling the button switch 20 for a short time, the lifting range of the glass can be reduced, and by toggling the button switch 20 for a long time, the lifting range of the glass can be increased or even completely opened or closed. Therefore, the first time period is to toggle the button switch 20 for a short time to detect the lifting function of the button switch 20 when the lifting range of the glass is small, and the second time period is to toggle the button switch 20 for a long time to detect the lifting function of the button switch 20 when the lifting range of the glass is large.

[0047] Preferably, the toggle block 41 includes a base block 410 slidably connected to the insertion rod 44 and a protrusion 411 fixed to the base block 410. In the sliding direction, a second elastic member is provided between the base block 410 and the insertion rod 44. The driving mechanism drives the toggle block 41 to toggle the button switch 20, which includes two strokes: in the first stroke, under the elastic force of the second elastic member, one side of the button switch 20 is toggled to a position where the detection device 1 can obtain the lifting function signal of the button switch 20, and the base block 410 and the insertion rod 44 do not slide relative to each other; in the second stroke, in the first stroke, under the elastic force of the second elastic member, one side of the button switch 20 is toggled to a position where the detection device 1 can obtain the lifting function signal of the button switch 20, and the base block 410 and the insertion rod 44 do not slide relative to each other. After the first stroke, the driving mechanism drives the toggle block 41 to continue to toggle one side of the button switch 20. Based on the squeezing effect between the button switch 20 and the protrusion 411, the base block 410 and the insertion rod 44 slide relative to each other, so that the protrusion 411 reaches the other side of the button switch 20. The first time period and the second time period both correspond to the time length during which one side of the button switch 20 is toggled to the position where the detection device 1 can obtain the lifting function signal position of the button switch 20 in the first stroke, and after the first time period ends, the driving mechanism does not drive the toggle block 41 to perform the second stroke.

[0048] Specifically, to detect the lifting function of the button switch 20, it is necessary to toggle the button switch 20 upward and downward. Correspondingly, whether it is toggled upward or downward, it is also necessary to test the lifting function at different toggling time lengths. Therefore, in this embodiment, the toggle block 41 is slidably connected to the insertion rod 44, and its sliding direction is a direction perpendicular to the toggle direction when it is squeezed by the button switch 20. If the toggle button switch 20 is up and down, that is, vertical, then the sliding direction between the base block 410 and the insertion rod 44 can be a certain horizontal direction, that is, a slideway 413 is provided on the base block 410, and a slider 412 is slidably set in the slideway 413. In the sliding direction, the slider 412 and the insertion rod 44 are A second elastic member is provided between the base blocks 410, and the protrusion 411 provided on the base block 410 is equivalent to the dividing line between the downward-moving button switch 20 and the upward-moving button switch 20. That is, taking the downward-moving button switch 20 as an example, under the driving force of the driving mechanism, the base block 410 moves downward, and the connection seam between the base block 410 and the protrusion 411 contacts the button switch 20 at a position facing the button switch 20. As the base block 410 continues to move downward, and under the elastic force provided by the second elastic member, no relative sliding is formed between the base block 410 and the insertion rod 44. Then, the protrusion 411 can be used to press the button switch 20 down to a position where the detection device 1 can detect the lifting function signal.

[0049] Among them, if a short-time toggle is required, then after the button switch 20 is pressed down to the position where the detection device 1 can detect the lifting function signal, the pressure on the button switch 20 is removed within one second. If a long-time toggle is required, then after the button switch 20 is pressed down to the position where the detection device 1 can detect the lifting function signal, the pressing time can be greater than one second. It can be seen that the short-time toggle button switch 20 and the long-time toggle button switch 20 both correspond to the first stroke.

[0050] Therefore, when testing the lifting function of the button switch 20, a short-time toggle can be performed first, and then a long-time toggle can be performed. That is, after the button switch 20 is toggled downward for a long time, the driving mechanism can continue to drive the base block 410 to move downward, and utilize the squeezing effect between the button switch 20 and the protrusion 411. The squeezing effect is formed by the wedge-shaped cooperation between the two, so that the base block 410 can squeeze the second elastic member, so that the slider 412 and the slideway 413 form relative sliding, and then the protrusion 411 moves downward from the upper surface side of the button to the lower surface side. At this time, the button switch 20 will also be reset under the action of the elastic structure rebound force of itself. Under the action of the rebound force of the second elastic member, the slider 412 returns to the initial position in the slideway 413, and then the base block 410 is driven to move upward by the driving mechanism, so that the connection gap between the protrusion 411 and the base block 410 is At the position corresponding to the button switch 20 above, the button switch 20 is pushed upward until the detection device 1 can detect the position of the lifting function signal. At this time, a short-term push is performed first, and then a long-term push is performed. After the long-term push, the driving mechanism can continue to drive the base block 410 to move upward, and the squeezing effect between the button switch 20 and the protrusion 411 is used again to allow the base block 410 to squeeze the second elastic member, so that the slider 412 and the slideway 413 form a relative sliding, and then move up the protrusion 411 from the lower surface side of the button to the upper surface side. Among them, the stiffness coefficient of the elastic structure of the button switch 20 itself is smaller than the stiffness coefficient of the second elastic member. When the button switch 20 is pushed to the point where it can no longer be pushed in this direction, it is the squeezing effect between the button switch 20 and the protrusion 411 that causes the elastic force of the second elastic member to change.

[0051] Preferably, the driving mechanism includes a plurality of first transmission plates 45 slidably arranged on the base plate 40, the plurality of first transmission plates 45 correspond one-to-one to the plurality of mounting plates 42, and the corresponding first transmission plates 45 are fixedly connected to the mounting plates 42, and a slide groove 46 is provided on the first transmission plate 45; it also includes a first driving branch chain and a second driving branch chain, the first driving branch chain drives the second driving branch chain to move circumferentially, and the second driving branch chain is provided with a squeezing ball 51, and the squeezing ball 51 can be slidably connected to any slide groove 46; when the squeezing ball 51 enters the slide groove 46, the second driving branch chain drives the squeezing ball 51 to squeeze the side wall of the slide groove 46, so as to drive the toggle block 41 to toggle the button switch 20.

[0052] Specifically, the sliding direction of the first transmission plate 45 on the base plate 40 corresponds to the direction in which the toggle block 41 toggles the button switch 20. The first transmission plate 45 can ensure that the toggle block 41 moves vertically, wherein the first drive branch chain drives the second drive branch chain to rotate circumferentially, that is, the first drive branch chain is a drive motor 47 arranged in the middle of the base plate 40, and the base plate 40 is also provided with an annular slide rail 48, and a slide seat 49 is slidably arranged on the annular slide rail 48. The second drive branch chain includes a first transmission rod 50 that slides vertically on the slide seat 49, and the extrusion ball 51 is fixedly connected to the lower section of the first transmission rod 50. A second transmission rod 52 is arranged between the upper end of the first transmission rod 50 and the power output end of the drive motor 47. The second transmission rod 52 consists of a telescopic main section and a sub-section. The main section is hinged to the power output end of the drive motor 47, and the sub-section is hinged to the first transmission rod 50. The upper end of the base plate 40 is hinged, and an annular groove 53 is also provided on the base plate 40. A moving block 54 is slidably provided in the annular groove 53. An electric push rod 55 is provided between the moving block 54 and the main section. When working, the driving motor 47 drives the second transmission rod 52 to move circumferentially, and the second transmission rod 52 can drive the first transmission rod 50 and the electric push rod 55 to move circumferentially together. The circumferential movement of the first transmission rod 50 can drive the slide 49 to move circumferentially on the annular slide rail 48. When the electric push rod 55 is telescopic, it can drive the second transmission rod 52 to swing up and down to drive the first transmission rod 50 to move up and down. In this way, when the squeezing ball 51 enters a certain slide groove 46, the up and down movement of the first transmission rod 50 can drive the squeezing ball 51 to squeeze the upper side wall or the lower side wall of the slide groove 46, so as to drive the toggle block 41 to toggle the button switch 20 up and down.

[0053] Furthermore, a locking mechanism is provided in the insertion rod 44. In a first time period, the locking mechanism locks the positions of the base block 410 and the insertion rod 44. In a second time period, the locking mechanism first locks the positions of the base block 410 and the insertion rod 44, and then releases the lock on the positions of the base block 410 and the insertion rod 44 based on the push of the squeezing ball 51.

[0054] Specifically, in the aforementioned embodiment, the elastic force of the second elastic member is utilized so that the base block 410 cooperates with the protrusion 411 to smoothly toggle the button switch 20. This may result in the following problem: if the elastic resistance exerted by the elastic structure of the button switch 20 itself is relatively large, and the second elastic member is no longer sufficient to provide support force for the base block 410 to cooperate with the protrusion 411 to toggle the button switch 20 due to long-term use, then when the button switch 20 is toggled, the button switch 20 cannot be toggled to a position where the detection device 1 can obtain the lifting function signal, which may cause the detection effect of the button switch 20 to deteriorate.

[0055] Therefore, in this embodiment, a locking mechanism is provided on the insertion rod 44, that is, when the push button switch 20 is toggled for a short time or for a long time, and the protrusion 411 does not need to pass over the push button switch 20 from one side to the other side, the locking mechanism always locks the position of the base block 410 and the insertion rod 44, that is, the slider 412 cannot slide in the slideway 413 under the action of external force at this time, thereby avoiding the above-mentioned problem.

[0056] Among them, after one of the button switches 20 is toggled for a short time, the next button switch 20 needs to be toggled next. Therefore, when the squeezing ball 51 passes through the slide groove 46, during this process, the locking mechanism should not apply an unlocking pushing force to the locking mechanism corresponding to the button switch 20 that has just been toggled. Therefore, in a further embodiment, the slide groove 46 includes two first sections 460 and a second section 461 connecting the two first sections 460, and the radial dimension of the first section 460 is smaller than the radial dimension of the second section 461; in the circumferential movement direction of the squeezing ball 51, the squeezing ball 51 squeezes the side wall of the first section 460 for the same time as the first time period; after squeezing the side wall of the first section 460, the squeezing ball 51 continues to squeeze the side wall of the second section 461 for the same time as the second time period, and in the process of squeezing the side wall of the second section 461, the locking mechanism releases the lock on the position of the base block 410 and the insertion rod 44 based on the push of the squeezing ball 51; the stroke of the squeezer squeezing the side wall of the other first section 460 corresponds to the second stroke.

[0057] That is, after the squeezing ball 51 squeezes the side wall of the first section 460, if the button switch 20 is toggled for the duration of the first time period, then after the squeezing ball 51 is separated from the first section 460, it will be driven back to the height when it initially entered the slide groove 46 (i.e., the vertical distance between the squeezing ball 51 and the substrate 40), and the toggle block 41 will also return to the initial position under the rebound force of the second elastic member, and then the squeezing ball 51 continues to move without contacting the locking mechanism. If the button switch 20 is toggled for the duration of the second time period, then After the squeezing ball 51 is separated from the first section 460, it is necessary to continue to change the distance between the squeezing ball 51 and the substrate 40 to squeeze the side wall of the second section 461. After the push button switch 20 is pushed for a required time, continuing to move will apply an unlocking thrust to the locking mechanism, so that the slider 412 and the slideway 413 are unlocked. Then, after the squeezing ball 51 contacts the other first section 460, it will continue to squeeze the side wall of the first section 460, so that the protrusion 411 can pass over one side of the push button switch 20 to the other side.

[0058] Preferably, the locking mechanism includes a locking rod 60 that is swingably set at the end of the rod 44 that is in sliding contact with the base block 410, and a third elastic member is provided at the swing axis of the locking rod 60. An extrusion rod 61 is also slidably provided in the rod 44. A locking groove 62 corresponding to the locking rod 60 is provided on the base block 410. Two levers 63 are symmetrically arranged with sliding as the symmetry axis on each first transmission plate 45. Power is transmitted between the two levers 63 and the corresponding extrusion rods 61 through a transmission assembly. The distance between the two levers 63 is the same as the radial dimension of the first section 460.

[0059] Specifically, one end of the locking rod 60 can be plugged into the locking groove 62 to achieve position restriction between the slider 412 and the slideway 413, and the other end is in contact with the lower end of the extrusion rod 61. When the extrusion rod 61 is moved downward by an external force, it will squeeze the other end of the locking rod 60 to swing downward, and then one end of the locking rod 60 will swing upward to disengage from the plugging in the locking groove 62, so as to achieve unlocking the position between the slider 412 and the slideway 413. The two levers 63 and the slideway 413 used to contact the extrusion ball 51 and transmit the thrust of the extrusion ball 51 are symmetrically arranged on the first transmission plate 45 as symmetry axes, and at the initial time, the distance between the two levers 63 is equal to the radial distance of the first section 460, that is, after the extrusion ball 51 squeezes the side wall of the first section 460, if the button switch 20 is toggled according to the length of the first time period, then between the extrusion ball 51 and the first section After 460 is disengaged, it will be driven back to the height when it initially entered the slide groove 46, and the toggle block 41 will also return to the initial position under the action of the rebound force of the second elastic member. After that, the squeezing ball 51 will continue to move and will not contact any of the levers 63. The lever 63 cannot be pushed by the squeezing ball 51, and the position lock between the slider 412 and the slide 413 cannot be released. If the button switch 20 is toggled according to the duration of the second time period, the squeezing ball 51 needs to squeeze the side wall of the second section 461. At this time, one of the levers 63 must be on the moving path of the squeezing ball 51, so the squeezing ball 51 will push the lever 63 to swing, and the swing of the lever 63 transmits power to the squeezing rod 61 through the transmission mechanism. The squeezing rod 61 squeezes the other end of the locking rod 60 to swing downward, so that one end of the locking rod 60 is disengaged from the locking slot, thereby releasing the position restriction on the slider 412 and the slide groove 46.

[0060] The transmission mechanism includes a first rod body 64 fixed to the swing axis of the lever 63, a second rod body 65 hinged to the first rod body 64, a second transmission plate 66 is slidably provided on the mounting plate 42, a fourth elastic member is provided between the second transmission plate 66 and the mounting plate 42, and a plurality of third rod bodies 67 are arranged on the second transmission plate 66, and the plurality of third rod bodies 67 correspond to the plurality of mounting holes 43 one by one. When the insertion rod 44 is plugged into any mounting hole 43, the third rod bodies 67 corresponding to the mounting hole 43 will squeeze the extrusion rod 61 in the insertion rod 44 when subjected to external force, that is, when the lever 63 is pushed by the extrusion ball 51, the swing of the lever 63 drives the first rod body 64 to swing together, the swing of the first rod body 64 pushes the second transmission plate 66 to move through the second rod body 65, and the second transmission plate 66 drives the plurality of third rod bodies 67 to enter their respective corresponding mounting holes 43, so that the third rod body 67 will produce an extrusion effect corresponding to the extrusion rod 61, so that the extrusion rod 61 squeezes the other end of the locking insertion rod 60 and swings down.

[0061] Furthermore, the length of the locking groove 62 is smaller than the protruding size of the protrusion 411; specifically, after the second elastic member has been used for a long time, the elastic function decreases, which will cause the slider 412 to be unable to return to the initial position in the slideway 413 based on the resilience of the second elastic member, and then the locking rod 60 and the locking groove 62 will be unable to be plugged in. Therefore, in order to avoid this situation, in this embodiment, the locking groove 62 is set to be a long strip, and the length is smaller than the protruding length of the protrusion 411. For example, if the protruding length of the protrusion 411 is three unit lengths, then the length of the locking groove 62 is one unit length. When the button switch 20 is squeezed, the slide 413 and the slider 412 are allowed to slide relative to each other a unit length, and the locking rod 60 and the locking groove 62 will still limit the relative movement of the slide 413 and the slider 412. This distance prevents the protrusion 411 from crossing the button switch 20. In this way, after the elastic function of the second elastic member decreases, the slider 412 cannot return to its initial position in the slide 413 by utilizing its rebound force, but the locking rod 60 and the locking groove 62 will still be plugged in, thereby extending the service life of the second elastic member. After the rebound force of the second elastic member is not sufficient to allow the locking rod 60 to be plugged in the locking groove 62, the second elastic member needs to be replaced.

[0062] During the detection of the button switch 20, if the button switch 20 is stuck or some structures connected to it are stuck, the toggle block 41 cannot toggle the button switch 20 under the driving force of the driving mechanism, and the force given to the toggle block 41 by the driving mechanism is set by the program, so the toggle force for each button switch 20 is certain. When the button switch 20 is stuck, if the same toggle force is applied, there is a risk of damaging the button switch 20. Therefore, in order to protect the button switch 20 from being damaged, the locking rod 60 is now set to a structure that can be broken when the force is too large, and a cavity 69 is now provided on the slider 412 for accommodating the locking rod 60 after it is broken, so as to protect the button switch 20, wherein the locking rod 60 is The connection between the plug rod 60 and the locking groove 62 does not require the locking plug rod 60 to swing along a longer path. After the locking plug rod 60 breaks, it cannot be obstructed by a section connected to the swing shaft to prevent the broken part of the locking plug rod 60 from continuing to obstruct the movement of the slider 412 in the slideway 413. Therefore, a vertex 68 is provided in the cavity 69 near the broken position of the locking plug rod 60. With the vertex 68 as the dividing line, the broken part of the locking plug rod 60 includes a long and short section, and the long section is a section connected to the locking groove 62. In the process of the locking plug rod 60 being broken by the force, the vertex 68 makes the broken part of the locking plug rod 60 form a force-saving lever and plays a guiding role, so that the broken part can deviate from the section connected to the swing shaft.
