[0032] The following describes the preferred embodiment with reference to the accompanying drawings to further illustrate the specific implementation of the present invention.

[0033] A pull-cord switch for a vehicle door comprises a housing mechanism, a circuit mechanism and a motion mechanism. The utility model facilitates the arrangement of the pull-cord switch on the vehicle door through the coordinated use of the housing mechanism, the circuit mechanism and the motion mechanism. At the same time, the conduction control of the circuit can be achieved through the mutual movement of the circuit mechanism and the motion mechanism, making it convenient to subsequently control the on and off of the pull-cord switch through the vehicle door handle.

[0034] In the present invention, the pull-rope switch is mainly used for door switch control. The pull-rope switch disclosed in the present invention mainly includes a shell mechanism, a circuit mechanism and a motion mechanism; the shell mechanism of the present invention is the main structure of the pull-rope switch, which plays an external protection role and facilitates subsequent installation and connection; in addition, the circuit mechanism mainly plays a connecting role, which facilitates the subsequent connection and connection with the wire 5, and the motion mechanism is mainly a moving part, which is convenient for subsequent use. The mutual connection of the circuit mechanisms forms a closed loop, realizes line conduction, and triggers the signal.

[0035] In the present invention, the circuit mechanism and the motion mechanism are arranged relatively on the shell mechanism; generally, the circuit mechanism and the motion mechanism are distributed at both ends of the shell mechanism, and the motion mechanism can reciprocate on the shell mechanism to achieve connectivity of the circuit mechanism; ultimately, circuit conduction is formed.

[0036] In addition, in the present invention, the housing mechanism includes a switch housing 6, and the interior of the switch housing 6 is hollow to form a placement cavity; the switch housing 6 is the main structure of the housing mechanism; it facilitates the installation and placement of the subsequent circuit mechanism and the motion mechanism, and the setting of the placement cavity facilitates the placement of the circuit mechanism, and at the same time provides an internal space for the coordinated use of the circuit mechanism and the motion mechanism.

[0037] The circuit mechanism described in the present invention includes a fixed conductive part arranged in the switch housing 6; in the present invention, the fixed conductive part is similar to the internal copper sheet structure of a traditional socket, which is mainly used to connect with the wire 5, so as to facilitate the subsequent contact with the conductive part to realize the wire 5 to form a closed loop, realize circuit conduction, and trigger the signal.

[0038] At the same time, in the present invention, the motion mechanism includes a pull rod 2; one end of the pull rod 2 is arranged inside the switch housing 6, and the other end extends to the outside of the switch housing 6; the pull rod 2 is a control part and a moving part. When used subsequently, it can drive the contact guide part to move, so as to facilitate the control of the contact between the contact conductive part and the fixed conductive part, thereby realizing the closed conduction of the wire 5.

[0039] In the present invention, a contact conductive part is provided at the end of the pull rod 2; the movement of the pull rod 2 can drive the contact conductive part to contact and conduct with the fixed conductive part; the contact conductive part acts as a bridge, mainly used to overlap the two conductive copper sheets 9 in the fixed conductive part, thereby realizing the conduction of the circuit.

[0040] Furthermore, in the utility model, the fixed conductive part includes two conductive copper sheets 9 distributed at intervals; the two conductive copper sheets 9 distributed at intervals in the utility model are fixed in the switch housing 6 and are connected to the wire 5, and the single wiring harness in the wire 5 is connected to a conductive copper sheet 9 respectively. Because the two conductive copper sheets 9 are distributed at intervals, when the contact conductive part is not in contact with the two conductive copper sheets 9, the two conductive copper sheets 9 are not connected to each other. During subsequent use, the pull rod 2 pulls the contact conductive part, and the contact conductive part contacts the two conductive copper sheets 9 at the same time, so as to easily realize the overlapping of the two conductive copper sheets 9, thereby realizing the connectivity of the wire 5, and facilitating the conduction of the line where the wire 5 is located.

[0041] At the same time, in the present invention, the conductive copper sheet 9 includes a straight section and a raised section; the raised section and the straight section are arranged to intersect; the straight section is mainly used to facilitate the fitting installation of the conductive copper sheet 9 on the bottom of the switch housing 6, while the raised section mainly serves as a protrusion, facilitating contact with the contact conductive part during subsequent use, and facilitating the overlap of the contact conductive part on the two conductive copper sheets 9.

[0042] Furthermore, in the present invention, the contact conductive portion includes a conductive copper sheet 4 provided at the end of the pull rod 2 ; the conductive copper sheet 4 is a plate structure, mainly for facilitating subsequent overlap on the raised sections of the two conductive copper sheets 9 .

[0043] In the present invention, the conductive copper sheet 4 includes a basic copper sheet, and a lateral copper sheet is respectively provided on the sides of the opposite sides of the basic copper sheet; the basic copper sheet acts as a connecting piece, and during subsequent installation, it is mainly connected to the end of the pull rod 2, while the lateral copper sheet mainly plays a connecting role to facilitate the subsequent contact and conduction between the conductive copper sheet 4 and the conductive copper sheet 9.

[0044] Furthermore, in the present invention, the motion mechanism also includes an elastic part sleeved on the pull rod 2, and the elastic part can drive the pull rod 2 to return to its position; the setting of the elastic part is mainly to limit the position of the pull rod 2. When the external force pulling the pull rod 2 disappears, the pull rod 2 automatically returns to its position under the pull of the elastic part, thereby realizing the separation of the contact conductive part and the fixed conductive part, and then realizing the disconnection of the line.

[0045] Specifically, in the present invention, the elastic part includes a reset spring 3, which is sleeved on the pull rod 2, and one end of the pull rod 2 is pressed against the contact conductive part, and the other end is pressed against the inner wall of the switch housing 6; the reset spring 3 is low in cost and convenient to install and arrange on the pull rod 2. In the present invention, the reset spring 3 is sleeved on the pull rod 2, and during subsequent use, the elastic component can be prevented from being separated from the pull rod 2, and the two ends of the reset spring 3 can be fixedly connected to the contact conductive part and the switch housing 6 respectively; of course, it can also be limited by size, and generally the outer diameter of the reset spring 3 is required to be smaller than the area of the contact conductive part. Such an arrangement; enables the reset spring 3 to only be sleeved on the pull rod 2, and there is no need to fix the end of the reset spring 3, which can reduce the difficulty of assembling the reset spring 3.

[0046] Furthermore, in the present invention, a fixing block 12 is provided on the switch housing 6, and a through hole is provided on the fixing block 12; the pull rod 2 is connected to the fixing block 12 through the through hole; the fixing block 12 acts as a connecting block and a guide block, which is conducive to ensuring the linearity and stability of the subsequent movement of the pull rod 2.

[0047] At the same time, in the present invention, the fixed block 12 is connected to the pull rod 2 through a guide component, and the guide component includes a flat key 11 arranged on the inner wall of the through hole; a guide key groove 14 is provided on the pull rod 2, and the flat key 11 is arranged in the guide key groove 14; in the present invention, the flat key 11 is fixed on the inner wall of the through hole, and the flat key 11 of the utility model is equivalent to being embedded in the guide key groove 14 of the pull rod 2. The position of the pull rod 2 can be limited by the restriction of the flat key 11, and the flat key 11 also has a good rotation limiting ability to prevent the pull rod 2 from rotating on the fixed block 12 or the switch housing 6.

[0048] Furthermore, in the utility model, the pull rod 2 is provided with a lifting screw 1 at one end away from the switch housing 6; the provision of the lifting screw 1 facilitates the subsequent connection between the pull rod 2 and the door handle through a pull rope. The lifting screw 1 mainly includes an end connecting ring and a connecting column. The connecting ring is connected to the end of the pull rod 2 through the connecting column. The connecting column and the pull rod 2 can be connected by threading, or by clamping or welding.

[0049] Furthermore, in the present invention, an adjusting nut 13 is provided on the pull rod 2; the pull rod 2 is provided with an external thread; the setting of the adjusting nut 13 is mainly to form an external protrusion on the outer surface of the pull rod 2, which plays a good limiting role.

[0050] That is, by limiting the position of the adjusting nut 13 , it is avoided that the setting of the elastic component causes the pull rod 2 to be inserted too far into the switch housing 6 .

[0051] Furthermore, in the present invention, a switch cover 8 is provided on the switch housing 6; the switch cover 8 is connected to the switch housing 6 in a detachable manner; screws can generally be used for connection, and reference can be made to the existing socket strip connection method.

[0052] At the same time, in the present invention, a fixing lug 10 is provided on the side of the switch housing 6; a plurality of fixing lugs 10 are provided on the side of the switch housing 6. When used subsequently, screws or bolts are passed through the fixing lugs 10 to connect it to the door interior panel. This arrangement facilitates the installation and connection of the switch housing 6 on the door. In actual use, the setting position and number of the fixing lugs 10 can be selected as needed. Specific embodiment:

[0054] The utility model discloses a pull rope switch for a vehicle door, which mainly comprises a motion mechanism, a circuit mechanism and a shell mechanism.

[0055] The motion mechanism includes: a lifting screw 1, a pull rod 2, a return spring 3, and a conductive copper sheet 4;

[0056] The circuit structure includes: a wire 5, a copper nose 7 and two conductive copper sheets 9 distributed at intervals; the wire 5 is connected to a conductive copper sheet 9 through the copper nose 7;

[0057] The outer structure includes: a switch housing 6 , a switch cover 8 , a C-shaped flat key 11 , a fixing block 12 , and an adjusting nut 13 .

[0058] The pull rope switch disclosed in the utility model has one end of the pull rope connected to the mechanical door handle inside the door and the other end connected to the eye screw 1 of the motion mechanism, and the switch housing 6 is fixed to the door interior panel.

[0059] As the door unlocking handle is pulled inside the car, the motion mechanism is pulled outward at the same time. When it is pulled to the specified position, it is equivalent to the pull rod 2 driving the conductive copper sheet 4 to overlap the raised sections of the two conductive copper sheets 9, thereby achieving circuit conduction and triggering the signal.

[0060] After releasing the hand, the movement mechanism returns to the initial position under the action of the return spring 3.

[0061] In order to prevent the pull rod 2 from deflecting and becoming chaotic during the pulling process, a guide key groove 14 is provided on the pull rod 2, and the C-shaped flat key 11 is assembled on the fixed block 12. During the movement of the pull rod 2, the C-shaped flat key 11 slides in the guide key groove 14 on the pull rod 2 to prevent the pull rod 2 from rotating, thereby avoiding erroneous triggering of the signal when the pull rod 2 rotates and increasing signal stability.

[0062] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the scope of protection of the present invention.
