[0002] In order to achieve rapid docking between various electrical components such as batteries, motors, and controllers and the wiring harness, connectors are usually used to quickly complete the connection, eliminating the need for complex wiring operations and thus greatly improving production efficiency. However, when existing electrical connectors are applied to the wiring harness connection of electric tricycles, after the connectors on the wiring harness are docked with the connectors at the electrical equipment, the docking part of the two is directly fixed on the vehicle body. However, in this connection method, most of the weight is concentrated at the docking part. Coupled with the bumps during vehicle driving, due to the lack of an effective protection structure for the connectors and their docking parts, under the action of vibration and impact, the connectors at the wiring harness and the connectors at the electrical equipment (the connection part of the two is simply referred to as the docking part) are extremely vulnerable to damage, greatly reducing the service life of the connectors and the stability of electrical connection, resulting in the phenomenon of "emphasizing docking and neglecting protection" in the use of this connection structure, thereby increasing the limitations in use of the structure.

[0014] The above embodiments of the present invention can achieve the following beneficial effects: (1) The pressure square plate reciprocates within the gas storage container, causing gas to be continuously generated inside it through the cooperation of the intake valve and the outlet valve and transported to the rectangular frame elastic airbag through the bent pipeline, causing it to expand. The expanded rectangular frame elastic airbag will come into contact with the vehicle body, thereby increasing the contact area between the A connector and the vehicle body, increasing the contact friction between the mounting square plate and the vehicle body, further improving the installation effect of the A connector, and enhancing the effect during the use of the docking component; at the same time, when the rectangular frame elastic airbag expands, it will produce elasticity, which also brings buffering performance. At the same time, through the buffering performance brought by the buffer rubber pad, the vibration and impact caused to the docking component during vehicle driving are reduced, effectively protecting the connection between the A connector and the B connector, thereby avoiding damage, dislocation, poor contact, etc. at the docking location, improving the service life of the connector, that is, the docking component, and the stability of the electrical connection, avoiding the phenomenon of "emphasizing docking and neglecting protection" in the use of the wire harness connection structure, effectively protecting the docking component. The impact energy such as vibration and sway during its use will be absorbed by the above-mentioned buffering performance, thereby reducing the limitations of the structure during use; (2) When the locking horizontal plate drives the locking plug towards the positioning square box to fix the B connector, at this time, the driving pulley is located on the side of the locking horizontal plate close to the positioning square box, which blocks the movement of the locking horizontal plate. During the docking process of the B connector, the driving screw rod will rotate, causing the driving threaded block to move limitedly on the auxiliary sliding column, driving the driving pulley to gradually release the limit setting on the locking horizontal plate. When the limit is released, the locking spring originally in a buffered state is reset, driving the locking plug on the locking horizontal plate to move back, passing through the positioning square box and connecting with one of the positioning slots, controlling the limiting time of the locking plug on the positioning square block, avoiding limiting the B connector before it moves to the specified installation position and affecting its normal use, ensuring that the B connector and the A connector are relatively fixed in position only after they are in the docking state, avoiding the docking state of the docking component being incomplete and affecting the stability of the electrical connection, thereby improving the connection effect of the connection structure and the use effect of the structure; it is worth mentioning that since the number of positioning slots is several, the initial position of the driving pulley can be controlled to limit the B connector at different positions, controlling the docking strength and state between the B connector and the A connector, further reducing the limitations of the structure during use; (3) The guiding cross plate drives the locking cross plate to move under the action of the locking cylinder and the locking spring, so that the locking plug on it will pass through the positioning square box and connect with one of the positioning slots, thereby limiting the positioning square block in the current position, fixing the B joint on it in the current position, completing the docking operation of the A joint and the B joint, and further fixing and setting on the basis of their docking, avoiding the phenomenon of dislocation of the docking parts due to non-human factors during use, further improving the connection effect and strength of the connection structure. At the same time, after the positioning square block is limited and the B joint is no longer pushed, the guiding spring and the positioning spring at the positioning damping device attempt to drive the gas-making square plate to reset and move synchronously. However, because the positioning square block in contact with the gas-making square plate is limited, the gas-making square plate cannot reset and move. The force generated acts on the positioning square block, increasing the connection strength and friction between the positioning slot and the locking plug, avoiding the dislocation of the locking plug due to non-human factors resulting in the dislocation of the B joint during use, and further improving the installation effect of the docking parts, ensuring the stability of the electrical connection between the A joint and the B joint, and thus reducing the limitations of the structure during use; (4) Through the resistance generated by the positioning spring and the guiding spring, a damping feeling is increased at the end of the docking operation of the B joint, which is used to control the moving speed of the end process in the docking operation, avoiding damage caused by excessive force used by the docking parts during the docking operation due to reasons such as the staff being unfamiliar with the equipment, resulting in the A joint and the B joint colliding with each other. Thereby, the connection effect of the wire harness during connection is further improved, the service life of the connection structure, that is, the connector (A and B joints), is improved, the docking parts are further protected, avoiding the phenomenon of "emphasizing docking and neglecting protection" during the use of the connection structure, and improving the stability of the electrical connection; (5) When the A joint and the B joint are docked together, the A joint can represent the connector at the electrical equipment, and the B joint can represent the connector at the wire harness. The A joint can be installed on the electric tricycle body through bolt parts, so that the mounting square plate on the A joint is installed on the vehicle body through bolt parts. At this time, the buffer rubber pad will contact the vehicle body, and the buffer rubber pad is located between the vehicle body and the mounting square plate. Through the buffer rubber pad, not only can the friction between the mounting square plate and the vehicle body be increased, avoiding the phenomenon of dislocation during the installation of the A joint due to position deviation during the installation process, and improving the installation effect of the A joint.

A through driving chute 15 is provided on the side of the driving moment block 14 facing the driving disc 12, and the driving cylinder 13 is located in the driving chute 15 and the two are slidably matched; The bottom of the driving moment block 14 is provided with two symmetrically arranged limiting slide columns 16, and the two limiting slide columns 16 are commonly slidably connected to a limiting base 17, and the limiting base 17 is connected to the positioning box 4; a gas storage container 18 is mounted on the top of the A connector 1, and a pressure square plate 19 that fits is slidably connected inside the gas storage container 18; the end of the limiting slide column 16 away from the driving moment block 14 passes through the top of the gas storage container 18 and is connected to the pressure square plate 19; An intake valve, which is mounted on one side of the gas storage container 18; An exhaust valve, which is connected to the other side of the gas storage container 18; A number of bolt members 32 are provided and are connected to the mounting square plate 7; a buffer rubber pad 33 is provided on the side of the mounting square plate 7 away from the docking member; A rectangular frame elastic airbag 34, whose inner periphery is connected to the outer periphery of the mounting square plate 7; A bent pipe 35, one end of which is mounted on the gas storage container 18 and is connected to the exhaust valve, and the other end is mounted on the bottom of the rectangular frame elastic airbag 34; When the operator uses the docking piece to dock the A connector 1 and the B connector 2 together, the A connector 1 can refer to the connector at the electrical equipment, and the B connector 2 can refer to the connector at the wiring harness. The A connector 1 can be installed on the electric tricycle body through the bolt member 32, so that the mounting square plate 7 on the A connector 1 is installed on the body through the bolt member 32. At this time, the buffer rubber pad 33 will contact the body, so that the buffer rubber pad 33 is located between the body and the mounting square plate 7. The buffer rubber pad 33 can not only increase the friction between the mounting square plate 7 and the body, but also avoid the phenomenon of dislocation caused by position deviation during the installation of the A connector 1, thereby improving the installation effect of the A connector 1; When the A joint 1 is installed on the vehicle body and the docking parts need to be docked, the B joint 2 is gradually inserted into the A joint 1, and the positioning block 3 on the B joint 2 is also inserted into the positioning box 4 on the A joint 1, which is used to guide the installation of the two joints to avoid deviation of the docking parts during docking and affect the use effect of the docking parts; at the same time, under the action of the positioning damping device, the positioning rack 31 is moved, so that it can engage the driving gear 9 to rotate, so that the driving disc 12 on it can rotate, so that the driving column 13 on it can reciprocate in the driving slide groove 15, so that the driving moment block 14 on it can be limited by the limiting slide column 16 at the limiting base 17, so as to drive the pressure square plate 19 to reciprocate in the gas storage container 18, so that the gas is continuously generated inside under the cooperation of the inlet valve and the outlet valve, and is transported to the square frame elastic airbag 34 through the bending pipe 35, so that it expands, and the expanded square frame elastic airbag The bag 34 will contact the vehicle body to increase the contact area between the A connector 1 and the vehicle body, so that the contact friction between the installation square plate 7 and the vehicle body can be increased, further improving the installation effect of the A connector 1, so that the effect of the docking piece when in use can be improved; at the same time, when the rectangular frame elastic airbag 34 expands, it will produce elasticity, which will bring about a buffering performance. At the same time, the buffering performance brought by the buffer rubber pad 33 can reduce the vibration and impact on the docking piece when the vehicle is driving, and can effectively protect the connection between the A connector 1 and the B connector 2, thereby avoiding damage to the docking point or causing dislocation, poor contact and other phenomena, improving the service life of the connector, that is, the docking piece, and the stability of the electrical connection, avoiding the phenomenon of "heavy docking and light protection" in the use of the wiring harness connection structure, and effectively protecting the docking piece. The impact energy such as vibration and shaking it is subjected to during use will be absorbed by the above-mentioned buffering performance, thereby reducing the limitations of the structure during use.

[0019] The positioning damping device of this embodiment includes a gas-making square plate 20, which is fitted and connected in the positioning square box 4 and the two are slidably matched; the opening of the positioning square box 4 faces the B joint 2, one side of the gas-making square plate 20 is located at the moving path of the positioning block 3, and the other side of the gas-making square plate 20 is equipped with two symmetrically arranged active square seats 21; On one side of the positioning square box 4 facing the gas-making square plate 20, there is a guiding sliding groove 22. A guiding sliding column 23 is installed in the guiding sliding groove 22. Two symmetrical guiding sliding blocks 24 are slidably connected to the guiding sliding column 23, and they are slidably arranged in the guiding sliding groove 22. A guiding spring 25 is sleeved on the guiding sliding column 23. Two ends of the guiding spring 25 are respectively fixedly connected to opposite faces of the two guiding sliding blocks 24. Two driven square seats 26 are installed on the two guiding sliding blocks 24. It includes two hinged square columns 27 arranged in an outward V shape. Two ends of the two hinged square columns 27 are respectively rotatably connected to the two driving square seats 21 and the two driven square seats 26. A positioning cylinder 28 is installed on the side of the gas-making square plate 20 away from the positioning square block 3. A positioning cylinder 29 is installed on one side of the positioning square box 4 facing the gas-making square plate 20. One end of the positioning cylinder 28 away from the gas-making square plate 20 is located in the positioning cylinder 29 and is slidably matched with the positioning cylinder 28. A positioning spring 30 is located in the positioning cylinder 29. One end of the positioning spring 30 is connected to the positioning cylinder 29, and the other end is connected to the positioning cylinder 28. One end of a positioning rack 31 is installed on each of the two driven square seats 26. The other end penetrates through the positioning square box 4 and extends to the outside and is meshed and connected with the driving gear 9. When the docking part is in use, that is, when the B connector 2 is connected to the relatively fixed A connector 1, since the A connector 1 is fixed to the vehicle body at this moment, it only needs to align the B connector 2 with the A connector 1 and insert it to complete the connection operation of the docking part. During the insertion process, the positioning square block 3 on the B connector 2 will gradually enter the positioning square box 4 at the B connector 2 to position the installation position of the B connector 2, so as to improve the accuracy and stability of the wire harness connection, and avoid deviation at the docking position or other non-human factors causing the B connector 2 to become disengaged from the A connector 1, thereby reducing the limitations during structural connection; at the same time, when the positioning square block 3 enters the positioning square box 4, it will make the positioning square block 3 contact the air-making square plate 20 in the positioning square box 4, which will push it to move in the positioning square box 4, so that the air-making square plate 20 makes the two guiding sliders 24 move away from each other at the guiding chute 22 and the guiding slide post 23 under the action of the driven square seat 26, the hinged square column 27 and the driving square seat 21, making the guiding spring 25 in a buffer state; when the air-making square plate 20 is moving, the positioning cylinder 28 on it will also be limited in movement in the positioning cylinder 29 to limit the movement of the air-making square plate 20, avoiding it shaking and driving the B connector 2 to shake together when moving, so as to improve the stability of the B connector 2 during docking, and improving the stability and effect of the wire harness connection structure during use; at the same time, the positioning spring 30 will also be in a buffer state. Through the resistance generated by the positioning spring 30 and the guiding spring 25, a damping feeling is increased at the end stage of the docking operation of the B connector 2, that is, to control the moving speed of the end process in the docking operation, and avoid damage caused by excessive force used by the docking parts during the docking operation due to the operator's unfamiliarity with the equipment and other reasons, resulting in the A connector 1 and the B connector 2 colliding with each other, thereby further improving the effect of the wire harness during connection, improving the service life of the connection structure, that is, the connector (A and B connectors), further protecting the docking parts, avoiding the phenomenon of "emphasizing docking and neglecting protection" in the use of the connection structure, and improving the stability of electrical connection.

[0020] The anti-disengagement and locking component of this embodiment is arranged at the auxiliary square column 6 and is used to strengthen the connection strength of the docking parts; one end of the auxiliary square column 6 is located inside the end point of the U-shaped pipe 5, and the other end is installed with a guiding cross plate 8; The L-shaped base 36 is installed at the output end of the U-shaped pipe 5; The auxiliary spring 37 is sleeved on the auxiliary square column 6; one end of the auxiliary spring 37 is fixedly connected to the L-shaped base 36, and the other end is fixedly connected to the guiding cross plate 8; two symmetric locking cylinders 38 are penetrated through one side of the guiding cross plate 8 close to the positioning square box 4, and a locking cross plate 39 is jointly connected to one end of the two locking cylinders 38 close to the positioning square box 4, and a locking insert block 40 is arranged on one side of the locking cross plate 39 away from the locking cylinder 38; On both sides of the positioning block 3, a number of equally spaced positioning slots 41 are provided; when the docking piece completes docking and the positioning block 3 is located inside the positioning box 4, at this time, the locking plug 40 passes through the positioning box 4 and is connected to one of the positioning slots 41; a locking spring 42 is sleeved on the locking cylinder 38, one end of the locking spring 42 is fixedly connected to the guiding cross plate 8, and the other end is fixedly connected to the locking cross plate 39; a driving threaded block 43 is threadedly connected to the driving lead screw 10, an auxiliary sliding column 44 is slidably connected to the driving threaded block 43, and the auxiliary sliding column 44 is installed on the driving base 11; a driving pulley 45 is installed on the driving threaded block 43, and it is located on the side of the locking cross plate 39 close to the positioning box 4; It includes an air delivery U-tube 46, the two ends of which are respectively connected to one side of the two positioning boxes 4 away from the positioning block 3; the air delivery U-tube 46 is communicated with the positioning box 4; one end of an L-shaped pipe 47 is respectively connected to both sides of the air delivery U-tube 46, and the other ends of the two L-shaped pipes 47 are respectively connected to the U-shaped pipe 5, and the U-shaped pipe 5 and the air delivery U-tube 46 are connected through the L-shaped pipe 47; When the B joint 2 is installed on the A joint 1, under the action of the positioning damping device, the gas-making square plate 20 is limited to move inside the positioning box 4, and its internal space is compressed, resulting in gas entering the U-shaped pipe 5 through the air delivery U-tube 46 and the L-shaped pipe 47. Thus, the gas acts on the auxiliary square columns 6 at both ends of the U-shaped pipe 5, which means it will push against the auxiliary square columns 6, making them limited to move at the ends of the U-shaped pipe 5, so that the auxiliary spring 37 is in a buffered state, thereby driving the guiding cross plate 8 to move towards the positioning box 4. The guiding cross plate 8 drives the locking cross plate 39 to move under the action of the locking cylinder 38 and the locking spring 42, so that the locking plug 40 on it passes through the positioning box 4 and is connected to one of the positioning slots 41, thereby limiting the positioning block 3 to the current position, fixing the B joint 2 on it to the current position, completing the docking operation of the A joint 1 and the B joint 2, and further fixing and setting on the basis of their docking, avoiding the phenomenon of dislocation of the docking piece due to non-human factors during use, further improving the connection effect and strength of the connection structure. At the same time, after the positioning block 3 is limited and set, the B joint 2 is no longer pushed, so that the guiding spring 25 and the positioning spring 30 at the positioning damping device attempt to drive the gas-making square plate 20 to reset and move synchronously. However, due to the positioning block 3 in contact with the gas-making square plate 20 being limited, the gas-making square plate 20 cannot reset and move, and the force brought acts on the positioning block 3, increasing the connection strength and friction between the positioning slot 41 and the locking plug 40, avoiding the dislocation of the locking plug 40 due to non-human factors resulting in the dislocation of the B joint 2 during use, thereby further improving the installation effect of the docking piece and ensuring the stability of the electrical connection between the A joint 1 and the B joint 2, thus reducing the limitations of the structure during use; It is worth mentioning that when the locking position cross plate 39 drives the locking position insert block 40 to move towards the positioning box 4 to fix the B joint 2, at this time, the driving pulley 45 is located on the side of the locking position cross plate 39 close to the positioning box 4, which blocks the movement of the locking position cross plate 39. At this time, the B joint 2 is in the docking process, so that the guiding cross plate 8 is limited in movement at the locking position cylinder 38, and the locking position spring 42 is in a buffered state. Since the gas-making square plate 20 will cause the two guiding sliders 24 to move away from each other when moving, it drives the positioning rack 31 to move to engage and drive the gear 9 to rotate, so that the driving screw rod 10 can be driven to rotate, and the driving thread block 43 connected by threads is limited in movement on the auxiliary sliding column 44, so as to drive the driving pulley 45 to move, and it moves on the surface of the locking position cross plate 39 to gradually release the limit setting for it; when the B joint 2 moves to the specified installation position, at this time, the driving pulley 45 is no longer connected to the locking position cross plate 39 to release the limit setting for it. At this time, the locking position spring 42 that was originally in a buffered state is reset, so that the locking position insert block 40 on the locking position cross plate 39 can be driven to move back, so that it can pass through the positioning box 4 and be connected to one of the positioning slots 41, so as to control the limiting time of the locking position insert block 40 on the positioning square block 3, avoid limiting the B joint 2 before it moves to the specified installation position, which affects its normal use, and ensure that the B joint 2 and the A joint 1 are relatively fixed in position only after they are in the docking state, avoid the docking state of the docking parts not being in place, which affects the stability of the electrical connection, thereby improving the connection effect of the connection structure and also improving the use effect of the structure; it is worth mentioning that since the number of the positioning slots 41 is several, the initial position of the driving pulley 45 can be controlled to limit the B joint 2 at different positions, so as to control the docking strength and state of the B joint 2 and the A joint 1, and further reduce the limitations of the structure in use.
