When the moving part 4 moves, the groove area corresponds to the position of the micro switch 3, and the micro switch 3 is not triggered, or the convex area resists the micro switch 3 to trigger the micro switch 3.

[0038] In one embodiment, Figure 1 As shown, the motor vehicle door lock signal control device includes a connecting plate 1, an unlocking member 2, a moving member 4, a micro switch 3, a driving mechanism 5 and a prompting device (not shown), wherein the unlocking member 2, the moving member 4, the micro switch 3 and the driving mechanism 5 are all installed on the connecting plate 1, and the micro switch is connected to the prompting device through a wired connection or a wireless connection. The prompting device is used to reflect the working status of the door lock.

[0039] Exemplarily, the moving part 4 rotates relative to the micro switch 3, and the moving part 4 includes an arc structure, and the groove area and the convex area are both located on the arc structure, wherein the convex area and the groove area are both located on the side wall of the moving part, and the groove area and the convex area are continuously arranged.

[0040] Exemplarily, the unlocking member 2 moves under the action of the driving mechanism 5 to drive the moving member 4 to move, and the unlocking member 2 is connected to the moving member 4 .

[0041] In one embodiment, the unlocking member 2 includes a gear member, such as a full gear member or a partial gear member. The driving mechanism 5 includes a driving motor and a driving gear (not shown) driven by the driving motor. The driving gear is meshed with the unlocking member 2, so that the unlocking member 2 is rotated around the rotation center 22 of the unlocking member under the action of the driving motor, and the rotation direction of the unlocking member 2 includes a clockwise direction or a counterclockwise direction. The unlocking member 2 is a mechanism used in the unlocking process and the locking process of the motor vehicle door lock. Specifically, when the rotation direction of the unlocking member is clockwise, it is the unlocking process, and when the rotation direction of the unlocking member is counterclockwise, it is the locking process.

[0042] In one embodiment, Figure 2 As shown, the moving member 4 is a cam, and the moving member 4 includes a first end and a second end that are arranged opposite to each other, and the first end of the moving member 4 is connected to the unlocking member 2, and the unlocking member 2 moves under the action of the driving mechanism 5 to drive the moving member 4 to move. Specifically, the first end of the moving member 4 is connected to the unlocking member 2, and the groove area and the convex area are arranged on the side wall of the second end of the moving member 4.

[0043] Exemplarily, the motor vehicle door lock signal control device further includes a connecting rod 21, a sliding groove 41 is provided on the moving part, one end of the connecting rod 21 is connected to the unlocking part 2, and the other end of the connecting rod 21 is provided in the sliding groove 41, and the unlocking part 2 can move by driving the connecting rod 21 to move in the sliding groove 41, so as to drive the movement of the moving part 4. Among them, the sliding groove 41 is arc-shaped, and the unlocking part 2 rotates to drive the connecting rod 21 to move in the sliding groove, so as to drive the moving part 4 to rotate.

[0044] In one embodiment, Figure 1 and Figure 2 As shown, the first end of the moving part 4 is connected to the unlocking part 2 through a connecting rod sliding groove mechanism, and the connecting rod sliding groove mechanism includes a sliding groove 41 opened at the first end of the moving part 4 and a connecting rod 21 fixedly arranged on the unlocking part 2, and the connecting rod 21 moves in the sliding groove 41.

[0045] Exemplarily, the groove area and the raised area are arranged on the other end of the moving part 4 relative to the driving mechanism 5, and the unlocking part 2 is arranged so that when the driving mechanism 5 drives the unlocking part 2 to rotate clockwise, the moving part 4 rotates counterclockwise, and when the driving mechanism 5 drives the unlocking part 2 to rotate counterclockwise, the moving part 4 rotates clockwise.

[0046] In one embodiment, the connecting rod sliding groove mechanism is arranged between the rotation center 22 of the unlocking member and the rotation center 44 of the moving part. When the unlocking member 2 rotates clockwise around the rotation center 22 of the unlocking member, the connecting rod 21 fixedly arranged on the unlocking member 2 slides in the sliding groove 41 opened on the moving part 4, driving the moving part 4 to rotate counterclockwise around the rotation center 44 of the moving part, and the second end of the moving part 4 also rotates counterclockwise; when the unlocking member 2 rotates counterclockwise around the rotation center 22 of the unlocking member, the connecting rod 21 fixedly arranged on the unlocking member 2 slides in the sliding groove 41 opened on the moving part 4, driving the moving part 4 to rotate clockwise around the rotation center 44 of the moving part, and the second end of the moving part 4 also rotates clockwise.

[0047] In one embodiment, when the rotation center 22 of the unlocking member, the connecting rod 21 and the rotation center 44 of the moving member are in a straight line, the position of the connecting rod 21 at this time is recorded as point O. When the current position of the connecting rod 21 gradually approaches point O as the unlocking member 2 rotates, the moving direction of the connecting rod 21 in the slide slot 41 is away from the first end of the moving member and close to the second end; when the current position of the connecting rod 21 is away from point O as the unlocking member 2 rotates, the moving direction of the connecting rod 21 in the slide slot 41 is away from the second end of the moving member and close to the first end. Taking the clockwise rotation of the unlocking member 2 as an example, when the unlocking member 2 rotates clockwise, the current position of the connecting rod 21 may gradually move away from point O, or may first gradually approach point O, then reach point O, and then gradually move away from point O. When the current position of the connecting rod gradually moves away from point O, the moving direction of the connecting rod 21 in the slide slot 41 is only away from the second end of the moving member to the first end. However, when the current position of the connecting rod 21 gradually approaches point O, then reaches point O, and then gradually moves away from point O, the moving direction of the connecting rod 21 in the slide groove 41 is first away from the first end of the moving part to the second end, and then away from the second end of the moving part to the first end.

[0048] In one embodiment, the unlocking member 2 drives the moving member 4 to move, and further includes converting the rotation of the unlocking member into the linear motion of the second end of the moving member, so that the moving member moves relative to the micro switch 3. For example, when the unlocking member 2 rotates clockwise, the second end of the moving member 4 moves upward, and when the unlocking member 2 rotates counterclockwise, the second end of the moving member 4 moves downward, and the present application does not limit this.

[0049] Exemplarily, the micro switch 3 includes a contact 31. When the contact of the micro switch is located in the groove area, the contact extends, and when the contact of the micro switch is located in the raised area, the contact retracts; when the contact retracts, the micro switch is triggered, and when the contact extends, the micro switch is not triggered.

[0050] In one embodiment, referring to Figure 2The second end of the moving member 4 includes a groove area 42 and a protruding area 43. When the contact 31 is located in the groove area 42, the contact 31 extends. When the contact 31 is located in the protruding area 43, the protruding area 43 abuts against the contact 31 to prevent the contact 31 from extending. Therefore, the contact 31 is in a retracted state. When the contact 31 is retracted, the micro switch 3 is turned on. When the contact 32 is extended, the micro switch 3 is turned off.

[0051] Exemplarily, the motor vehicle door lock signal control device includes a plurality of trigger parts and a corresponding number of micro switches 3, the trigger parts are all located on the moving part 4, each trigger part corresponds to a different micro switch 3, each trigger part includes at least one raised area and one groove area, and the raised area and the groove area located on the same trigger part are arranged continuously, and are arranged so that the movement of the moving part can trigger at least some of the micro switches 3 to reflect the working status of the door lock.

[0052] Exemplarily, the triggering parts corresponding to the two micro switches 3 are arranged adjacent to each other, and the two triggering parts are arranged alternately, so that at least a part of the raised area of ​​one triggering part corresponds to at least a part of the groove area of ​​the other triggering part.

[0053] It should be noted that each motor vehicle door lock signal control device may include one or more moving parts 4, one or more trigger parts may be set on each moving part 4, each trigger part corresponds to a micro switch 3, and the present application does not limit the number of moving parts 4 and the number of micro switches 3 set corresponding to each moving part 4.

[0054] In one embodiment, a motor vehicle door lock signal control device includes a moving part 4 and two micro switches 3. Accordingly, two trigger parts are provided at the second end of the moving part 4. The three working states of the door lock are reflected based on the triggered or untriggered states of the two micro switches 3. The prompt device can reflect the working state of the door lock by light signals, sound signals and / or text signals.

[0055] In one embodiment, the two micro switches include a first micro switch having a first contact and a second micro switch having a second contact. The first contact and the second contact are arranged in parallel or nearly in parallel (for example, the angle is less than 10°). Figure 2As shown, the two triggering parts at the second end of the moving part 4 are also arranged in parallel or nearly in parallel, the first triggering part (i.e., the upper triggering part) corresponds to the position of the first contact, and the second triggering part (i.e., the lower triggering part) corresponds to the position of the second contact. The first triggering part includes a convex area and a groove area that are continuously arranged, and the second triggering part includes a convex area and a groove area that are continuously arranged. The first triggering part and the second triggering part are arranged adjacent to each other and staggered, so that at least part of the convex area of ​​the first triggering part corresponds to at least part of the groove area of ​​the second triggering part, and at least part of the convex area of ​​the second triggering part corresponds to at least part of the groove area of ​​the first triggering part. In this way, the adjacent first triggering part and the second triggering part can form a plurality of continuous signal areas in sequence by staggered arrangement, for example, from left to right, an upper convex and lower concave area, an upper concave and lower concave area, and an upper concave and lower convex area.

[0056] In one embodiment, when the vehicle is driving normally, the first contact and the second contact are in the concave-upper and concave-lower regions of the moving part 4, at which time the first contact and the second contact are both extended, the first micro switch and the second micro switch are both not triggered, and are in the second signal state, for example, the return-to-center state. At this time, if the driving mechanism 5 starts to drive the unlocking member 2 to rotate clockwise, the moving part 4 rotates counterclockwise, the first contact and the second contact move from the concave-upper and concave-lower regions to the convex-upper and concave-lower regions, at which time the first contact retracts and the second contact extends, the first micro switch is triggered and the second micro switch is not triggered, and the second signal state switches to the first signal state, for example, the unlocking state. If the driving mechanism 5 drives the unlocking member 2 to rotate counterclockwise, the moving part 4 rotates clockwise, the first contact and the second contact move from the concave-upper and concave-lower regions to the concave-upper and convex-downer regions, at which time the first contact extends and the second contact retracts, the first micro switch is not triggered and the second micro switch circuit is triggered, and the second signal state switches to the third signal state, for example, the locking state.

[0057] In one embodiment, the correspondence between the signal state of the micro switch (e.g., the first signal state, the second signal state, the third signal state or other signal states) and the door lock state (e.g., unlocked state, locked state, returned to center state or other states) can be set as needed, and this application does not impose any restrictions on this.

[0058] The utility model also provides a vehicle, comprising the above motor vehicle door lock signal control device.

[0059] According to the motor vehicle door lock signal control device, motor vehicle door lock and vehicle provided by the utility model, the micro switch is controlled to be turned on or off through the cooperation of the moving part and the micro switch. Since the manufacturing precision of the moving part is low and the micro switch is easy to purchase, the design and manufacturing cost of the motor vehicle door lock signal control device is reduced, a large amount of mold development investment is reduced, and cost reduction and efficiency improvement are achieved.
