Description

[0002] In order to achieve rapid docking between various electrical components such as batteries, motors and controllers and wiring harnesses, connectors are usually used to quickly complete the connection without the need for complicated wiring operations, thereby greatly improving production efficiency. However, when existing electrical connectors are used for electric tricycle wiring harness connections, after the staff completes the docking of the connector on the wiring harness with the connector at the electrical equipment, they will directly fix the docking point of the two on the vehicle body. However, under this connection method, most of the weight is concentrated at the docking point, and coupled with the bumps when the vehicle is driving, due to the lack of an effective protection structure for the connector and its docking point, under the action of vibration and impact, the connector at the wiring harness and the connector at the electrical equipment (the connection point between the two is referred to as the docking point) are extremely susceptible to damage, which greatly reduces the service life of the connector and the stability of the electrical connection, resulting in the phenomenon of "heavy docking and light protection" when the connection structure is in use, thereby increasing the limitations of the structure when in use.

[0031] The above embodiments of the present invention can achieve the following beneficial effects:

[0032] (1) The pressure square plate moves back and forth in the gas storage container, so that the gas is continuously generated in the interior of the gas storage container under the cooperation of the inlet valve and the outlet valve and is transported to the rectangular frame elastic airbag through the bent pipe, causing it to expand. The expanded rectangular frame elastic airbag will contact the vehicle body to increase the contact area between the A connector and the vehicle body, so that the contact friction between the installation square plate and the vehicle body can be increased, further improving the installation effect of the A connector and improving the effect of the docking part during use. At the same time, when the rectangular frame elastic airbag expands, it will produce elasticity, which will bring about buffering performance. At the same time, the buffering performance brought by the buffering rubber pad can reduce the vibration and impact caused to the docking part during driving of the vehicle, and effectively protect the connection between the A connector and the B connector, thereby avoiding damage to the docking part or causing dislocation, poor contact, etc., improving the service life of the connector, that is, the docking part, 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 part. The impact energy such as vibration and shaking it receives during use will be absorbed by the above-mentioned buffering performance, thereby reducing the limitations of the structure during use.

[0033] (2) When the locking cross plate drives the locking plug to move toward the positioning box to fix the B joint, the driving pulley is located on the side of the locking cross plate close to the positioning box, which blocks the movement of the locking cross plate. During the docking process of the B joint, the driving screw will rotate, causing the driving thread block to move within the upper limit of the auxiliary slide column, thereby driving the driving pulley to gradually release the limit setting on the locking cross plate. After the limit is released, the locking spring that was originally in the buffer state is reset, so that it can drive the locking plug on the locking cross plate to reset and move, so that it can pass through the positioning box and connect with one of the positioning slots, thereby controlling the locking plug to be fixed to the positioning box. The limiting time of the positioning block prevents connector B from being limited before it moves to the designated installation position, which would affect its normal use. It ensures that connector B and connector A are fixed in relative position only after they are in the docking state, avoiding the impact of improper docking of the docking parts on the stability of the electrical connection, thereby improving the connection effect of the connection structure and the performance of the structure. It is worth mentioning that due to the number of positioning slots, the initial position of the driving pulley can be controlled to limit connector B at different positions, so that the docking strength and state of connector B and connector A can be controlled, further reducing the limitations of the structure during use.

[0034] (3) The locking cylinder and the locking spring of the guide cross plate drive the locking cross plate to move, so that the locking block on it passes through the positioning box and connects with one of the positioning slots, thereby limiting the positioning block to the current position, fixing the B joint on it to the current position, completing the docking operation of the A joint and the B joint, and further fixing the setting on the basis of the docking of the two, 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, and at the same time, after the positioning block is limited, it no longer pushes the B joint. , the guide spring and the positioning spring at the positioning damping device attempt to synchronously drive the gas control square plate to reset and move. However, because the positioning block in contact with the gas control square plate is limited, the gas control square plate cannot reset and move. The resulting force acts on the positioning block, thereby increasing the connection strength and friction between the positioning slot and the locking plug, preventing the locking plug from dislocating due to non-human factors and causing the B connector to dislocate during use, thereby further improving the installation effect of the docking parts, ensuring the stability of the electrical connection between the A connector and the B connector, and reducing the limitations of the structure during use;

[0035] (4) The resistance generated by the positioning spring and the guide spring increases the damping feeling at the end of the docking operation of the B connector, which is used to control the moving speed of the final process in the docking operation, and avoid the A connector and the B connector colliding with each other and causing damage due to the staff's unfamiliarity with the equipment. This further improves the effect of the wiring harness during connection, and the service life of the connection structure, that is, the connector (A, B connector) can be improved, further protects the docking parts, avoids the phenomenon of "heavy docking and light protection" when the connection structure is in use, and improves the stability of the electrical connection;

[0036] (5) When the A connector and the B connector are connected together, the A connector can refer to the connector at the electrical equipment, and the B connector can refer to the connector at the wiring harness. The A connector can be installed on the electric tricycle body through bolts, so that the installation square plate on the A connector is installed on the body through bolts. At this time, the buffer rubber pad will contact the body, so that the buffer rubber pad is located between the body and the installation square plate. The buffer rubber pad can not only increase the friction between the installation square plate and the body, but also avoid the position shift during the installation of the A connector, resulting in dislocation of the installation, thereby improving the installation effect of the A connector.

[0064] A bent pipe 35, one end of which is mounted on the gas storage container 18 and connected to the gas outlet valve, and the other end is mounted on the bottom of the rectangular elastic airbag 34;

[0065] 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 mounted on the vehicle body through the bolt member 32.

[0081] When the locking plate 20 is in the process of docking, the guide plate 8 is limited to move at the locking cylinder 38, so that the locking spring 42 is in a buffering state. When the air-control plate 20 moves, the two guide sliders 24 move back and forth, thereby driving the positioning rack 31 to move to engage the driving gear 9 and rotate it, so that it can drive the driving screw 10 to rotate, so that the threaded driving screw block 43 is limited to move on the auxiliary slide post 44, thereby driving the driving pulley 45 to move, so that it moves on the surface of the locking plate 39, so as to gradually release its limit setting; when the B joint 2 moves to the designated installation position, the driving pulley 45 is no longer connected with the locking plate 39 to release it. The limit setting, at this time, makes the locking spring 42 which was originally in the buffer state reset the setting, so that it can drive the locking plug 40 on the locking cross plate 39 to reset and move, so that it can pass through the positioning box 4 and connect with one of the positioning slots 41, so as to control the limiting time of the locking plug 40 on the positioning block 3, to avoid limiting the B connector 2 before it moves to the designated installation position, thereby affecting its normal use, to ensure that the positions of the B connector 2 and the A connector 1 are relatively fixed only after they are in the docking state, to avoid the docking state of the docking parts not being in place affecting the stability of the electrical connection, thereby improving the connection effect of the connection structure, and the use effect of the structure is also improved; it is worth mentioning that since there are several positioning slots 41, the initial position of the driving pulley 45 can be controlled to limit the B connector 2 at different positions, so as to control the docking strength and state of the B connector 2 and the A connector 1, further reducing the limitations of the structure during use.
