[0039] In one embodiment, as shown in Figure 1 and Figure 2 The gear power unlocking device 100 of the track walking mechanism provided by the embodiment of the present application includes a driving device, the driving device includes a device shell 210 and a motor gear 220 and a transmission gear 230 arranged in the device shell 210 respectively, and the gear power unlocking device 100 specifically can include a gear connection module 110, a lever transmission module 120 and an unlocking power module 130. Wherein, the gear connection module 110 includes a gear pulling shaft 111 and a gear connecting piece 112, the gear pulling shaft 111 includes a first end located in the device shell 210 and a second end protruding from the surface of the device shell 210, and the central axis of the gear pulling shaft 111 passes through the center of the motor gear 220, the first end is rotationally provided with the gear connecting piece 112, and the gear connecting piece 112 is used for fixedly connecting with the motor gear 220. The lever transmission module 120 includes a transmission lever 121 and a fulcrum fixing piece 122, the fulcrum fixing piece 122 is arranged on the surface of the device shell 210, the middle part of the transmission lever 121 is rotationally connected with the fulcrum fixing piece 122, one end of the transmission lever 121 is movably connected with the second end, so that when the transmission lever 121 performs lever movement, the gear pulling shaft 111 is moved back and forth along the length direction of the gear pulling shaft 111. The unlocking power module 130 is movably connected with the other end of the transmission lever 121, and is used for driving the other end of the transmission lever 121 to move, so that the transmission lever 121 performs lever movement.

[0040] It can be understood that the gear power unlocking device 100 mentioned in the embodiments of the present application is mainly used in a track walking mechanism such as a patrol robot, to release the meshing state between the motor gear 220 and the transmission gear 230 of the driving device, so that the track walking mechanism can be moved smoothly by artificial. Generally, the motor gear 220 is sleeved on the motor shaft of the fixed driving motor to be driven to rotate normally by the motor shaft, so that in order to better realize the fastening connection between the gear connecting piece 112 and the motor gear 220, the gear connecting piece 112 is generally arranged on the side of the motor gear 220 away from the driving motor. At the same time, the gear pulling shaft 111 is generally arranged coaxially with the motor shaft of the driving motor, so that when the gear pulling shaft 111 moves back and forth along the length direction of the gear pulling shaft 111, the motor gear 220 can be driven to move back and forth along the axial direction of the motor shaft of the driving motor through the gear connecting piece 112, so as to make the motor gear 220 and the transmission gear 230 disengage (i.e. release the meshing state) or restore the meshing state. The unlocking power module 130 mentioned above can be a conventional automatic stretching structure with a power source or a conventional manual stretching structure without a power source according to actual needs, as long as it can drive the other end of the transmission lever 121 to move, so that the transmission lever 121 can perform lever movement. Figure 2 As an example, when the other end of the transmission lever 121 is driven by the unlocking power module 130 to move to the left, one end of the transmission lever 121 can be moved to the right through the lever movement of the transmission lever 121, so as to drive the gear pulling shaft 111 to move to the right along the length direction of the gear pulling shaft 111, so that the motor gear 220 is driven to move to the right along the axial direction of the motor shaft of the driving motor through the gear connecting piece 112, so as to make the motor gear 220 and the transmission gear 230 disengage (i.e. release the meshing state). Conversely, when the other end of the transmission lever 121 is reset by the unlocking power module 130, the gear pulling shaft 111 can be driven to move to the left along the length direction of the gear pulling shaft 111 through the reverse lever movement of the transmission lever 121, so that the motor gear 220 is driven to move to the left along the axial direction of the motor shaft of the driving motor through the gear connecting piece 112, so as to make the motor gear 220 and the transmission gear 230 restore the meshing state.

[0041] Thus, the gear power unlocking device 100 of the track walking mechanism provided by the embodiment of the present application, through the above structural arrangement, when the motor gear 220 is working normally, since the central axis of the gear pulling shaft 111 of the gear power unlocking device 100 penetrates the center of the motor gear 220, and the gear connecting piece 112 and the first end of the gear pulling shaft 111 are rotationally connected, the gear connecting piece 112 of the gear power unlocking device 100 can rotate synchronously with the motor gear 220 around the central axis of the gear pulling shaft 111, without affecting the normal rotation of the motor gear 220. At this time, since the motor gear 220 and the transmission gear 230 remain in the normal meshing state, the motor gear 220 can drive the transmission gear 230 to normally output power. When the corresponding driving device fails to operate, the gear power unlocking device 100 only needs to drive the other end of the transmission lever 121 of the unlocking power module 130 to move, so that the transmission lever 121 performs lever movement, and one end of the transmission lever 121 drives the gear pulling shaft 111 to move back and forth along the length direction of the gear pulling shaft 111, so as to make the motor gear 220 and the transmission gear 230 disengage (i.e. disengage) or restore the meshing state. That is, the gear power unlocking device 100 can quickly disengage and restore the meshing state of the gear of the driving device.

[0042] In some examples, as shown in Figure 1 and Figure 2 The gear connecting piece 112 includes a disc part (not marked in the figure) and a sleeve part (not marked in the figure) arranged in sequence, wherein the side of the disc part away from the sleeve part is attached to one side surface of the motor gear 220, and the disc part is fixedly connected with the motor gear 220. The sleeve part is sleeved on the first end away from the disc part, and the sleeve part is rotationally connected with the first end, and the central axis of the sleeve part penetrates the center of the disc part and the center of the motor gear 220 in sequence. In this way, through the above structural arrangement, the gear connecting piece 112 can be rotationally arranged on the first end of the gear pulling shaft 111 while being fixedly connected with the motor gear 220. Further, the disc part and the motor gear 220 are fixedly connected through a screw structure or a buckle structure, which can ensure the firm connection between the disc part and the motor gear 220. The sleeve part and the first end are rotationally connected through a bearing structure, which can ensure that the sleeve part rotates more stably relative to the first end.

[0043] It can be understood that the one side surface of the motor gear 220 in the present example specifically refers to the one side surface of the motor gear 220 away from the driving motor.

[0044] In some examples, as shown in Figures 1 to 3As shown, the unlocking power module 130 includes a module housing 131, a power slider 132, a power rod 133, a first compression spring 134, and a pull rod 135 with an operating portion (not shown), wherein the power slider 132 is slidingly arranged in the module housing 131 along the length direction of the gear pulling shaft 111. One end of the power rod 133 is movably connected with the other end of the transmission lever 121, and the other end of the power rod 133 penetrates the module housing 131 and is fixedly connected with one end of the power slider 132 in the module housing 131. The end of the pull rod 135 away from the operating portion penetrates the module housing 131 and is fixedly connected with the other end of the power slider 132 in the module housing 131. The first compression spring 134 is sleeved on the end of the pull rod 135 away from the operating portion, and one end of the first compression spring 134 abuts against the power slider 132, and the other end of the first compression spring 134 abuts against the module housing 131. In this way, through the above structural arrangement, the user can pull the pull rod 135 through the operating portion, so that the power slider 132 slides in the right direction as shown in Figure 3 , and in turn drives the power rod 133 to move in the right direction as shown in Figure 3 at the same time. At this time, the other end of the transmission rod can move under the transmission of the power rod 133, so that the transmission lever performs corresponding lever movement, so that the motor gear 220 and the transmission gear 230 are decoupled. When the user releases the pull rod 135 through the operating portion, the power slider 132 can slide in the left direction as shown in Figure 3 under the elastic restoring force of the first compression spring 134, and in turn drives the power rod 133 to move in the left direction as shown in Figure 3 at the same time. At this time, the other end of the transmission rod can move reversely under the transmission of the power rod 133, so that the transmission lever performs corresponding reverse lever movement, so that the motor gear 220 and the transmission gear 230 are restored to the meshing state.

[0045] In some examples, as shown in Figures 1 to 3 , a preset surface of the power slider 132 is recessed with a guide groove body 1321, and a guide protrusion 1322 is protruded in the middle of the guide groove body 1321, so as to form an annular guide groove by surrounding the guide protrusion 1322 and the side wall of the guide groove body 1321. The preset surface is a side surface of the power slider 132 parallel to the sliding direction of the power slider 132. The unlocking power module 130 further includes a double-headed connecting rod 136 arranged in the device housing 210, one end of the double-headed connecting rod 136 is rotatably arranged, and the other end of the double-headed connecting rod 136 is protruded with a limiting portion 1361, the limiting portion 1361 is arranged in the annular guide groove and performs annular movement under the guidance of the annular guide groove when the power slider 132 slides. In this way, through the above structural arrangement, when the motor gear 220 and the transmission gear 230 are in the meshing state, the limiting portion 1361 is in the annular guide groove, and the double-headed connecting rod 136 is in the state of being rotatably arranged. When the user pulls the pull rod 135 through the operating portion, the power slider 132 slides in the right direction as shown in Figure 3The position shown is located at one end of the guide protrusion 1322 adjacent to the pull rod 135. At this time, when the user pulls the pull rod 135 through the operating part, the power slider 132 can move along... Figure 3 As shown, it slides to the right, while the limiting part 1361 can move along... Figure 3 The lower half of the annular guide groove shown moves to the guide protrusion 1322 near one end of the power rod 133. At this time, when the user releases the pull rod 135 through the operating part, the limiting part 1361 can stop at the current position (i.e., located at one end of the guide protrusion 1322 near the power pull rod 135) under the elastic restoring force of the first compression spring 134, so that the motor gear 220 and the transmission gear 230 remain disengaged. When the user pulls the pull rod 135 again through the operating part, the power slider 132 moves along the... Figure 3 When the sliding trend in the right direction is shown, the limiting part 1361 will enter... Figure 3 The upper half of the annular guide groove shown is such that when the user releases the lever 135 again via the operating part, the power slider 132 moves along the elastic restoring force of the first compression spring 134. Figure 3 When sliding to the left as shown, the limiting part 1361 can simultaneously move along the elastic restoring force of the first compression spring 134. Figure 3The upper half of the annular guide groove shown in the middle returns to the end of the guide protrusion 1322 adjacent to the pull rod 135, so that the motor gear 220 and the transmission gear 230 are restored to the state of engagement. Further, the end of the guide protrusion 1322 adjacent to the power rod body 133 is formed with a first limiting structure matched with the side wall of the corresponding guide groove body 1321. In this way, the first limiting structure can be set when the limiting block moves to the end of the guide protrusion 1322 adjacent to the power rod body 133, and more stably stays in the current position, so that the motor gear 220 and the transmission gear 230 remain disengaged. The end of the guide protrusion 1322 adjacent to the pull rod 135 is formed with a second limiting structure matched with the side wall of the corresponding guide groove body 1321. In this way, the second limiting structure can be set when the limiting block moves to the end of the guide protrusion 1322 adjacent to the pull rod 135, and more stably stays in the current position, so that the motor gear 220 and the transmission gear 230 remain engaged. Further, the first limiting structure is provided with a first guide for guiding the limiting part 1361 to move in the first direction when the power slider 132 slides. In this way, by setting the first guide, when the limiting block moves to the end of the guide protrusion 1322 adjacent to the power rod body 133, it can not only more stably stay in the current position through the first limiting structure to make the motor gear 220 and the transmission gear 230 remain disengaged, but also make the limiting part 1361 quickly escape from the first limiting structure through the cooperation of external force (i.e. the action of making the power slider 132 slide) and the first guide when the motor gear 220 and the transmission gear 230 need to be restored to the state of engagement. Similarly, the second limiting structure is provided with a second guide for guiding the limiting part 1361 to move in the second direction when the power slider 132 slides, and the second direction is set in the opposite direction of the first direction. In this way, by setting the second guide, when the limiting block moves to the end of the guide protrusion 1322 adjacent to the pull rod 135, it can not only more stably stay in the current position through the second limiting structure to make the motor gear 220 and the transmission gear 230 remain engaged, but also make the limiting part 1361 quickly escape from the second limiting structure through the cooperation of external force (i.e. the action of making the power slider 132 slide) and the second guide when the motor gear 220 and the transmission gear 230 need to be disengaged.

[0046] It can be understood that the rotation of one end of the double-headed connecting rod 136 in the example refers to the rotation connection of one end of the double-headed connecting rod 136 with the inner wall of the module shell 131. The first limiting structure in the example can be that the triangular groove adjacent to one end of the power rod body 133 of the guide protrusion 1322 cooperates with the triangular protrusion on the side wall of the corresponding guide groove body 1321 to form a limiting structure. The second limiting structure in the example can be that the triangular protrusion adjacent to one end of the pull rod 135 of the guide protrusion 1322 cooperates with the triangular groove on the side wall of the corresponding guide groove body 1321 to form a limiting structure. The first direction in the example can be the upward movement direction shown in Figure 3 , at this time, the first guide in the example can be that the guide protrusion 1322 adjacent to one end of the power rod body 133 is provided with an upward guide slope on the side wall of the corresponding guide groove body 1321. The second direction in the example can be the downward movement direction shown in Figure 3 , at this time, the second guide in the example can be that the guide protrusion 1322 adjacent to one end of the pull rod 135 is provided with a downward guide slope.

[0047] In some examples, as shown in Figures 1 to 3 , the preset surface is perpendicular to the horizontal plane, and the first limiting structure and the second limiting structure are located on the same horizontal line (i.e., the heights of the two are the same). The unlocking power module 130 further includes a tension spring 138 fixing piece 137 and a tension spring 138, the tension spring 138 fixing piece 137 is fixedly arranged above the limiting portion 1361, one end of the tension spring 138 is fixedly connected with the tension spring 138 fixing piece 137, and the other end of the tension spring 138 is fixedly connected with the limiting portion 1361, so that the limiting portion 1361 maintains a balanced state in the first limiting structure or the second limiting structure under the elastic force of the tension spring 138 and the gravity of the double-headed connecting rod 136. In this way, through the above structural arrangement, it can be ensured that the limiting portion 1361 always performs corresponding circular motion along the guide of the annular guide groove.

[0048] In some examples, as shown in Figure 1 and Figure 2 , the gear connection module 110 further includes a second compression spring 113, the second compression spring 113 is sleeved on the first end, and one end of the second compression spring 113 abuts against the device shell 210. One end of the second compression spring 113 abuts against the gear connecting piece 112. In this way, through the above structural arrangement, when it is required to restore the meshing state of the motor gear 220 and the transmission gear 230, the second compression spring 113 can drive the gear connecting piece 112 to move reversely together with the first compression spring 134 to restore the meshing state of the motor gear 220 and the transmission gear 230.

[0049] In some examples, as shown in Figure 1And Figure 2 As shown in the figure, one end of the transmission lever 121 is provided with a first limiting long hole (not marked in the figure), and the opening direction of the first limiting long hole is perpendicular to the length direction of the gear pulling shaft 111.
