Technical Field

[0001] This utility model relates to the field of synchronous transmission technology for automotive top and bottom locks, specifically an electrically operated self-priming transmission mechanism. Background Technology

[0002] A car door lock is a combination of two locks, one above the other, located on the door. A regular car door only has one lock, but a door without a B-pillar requires a combination of locks to ensure the door's strength in a side impact. Therefore, the door lock is an important part of the car's safety system.

[0003] Because the top and bottom locks are two locks installed on one car door, the traditional transmission structure of the top and bottom locks has relatively poor transmission synchronization, resulting in the car door not opening smoothly. Utility Model Content

[0008] And a second transmission component, connected to the connecting plate, which activates upon receiving a vehicle body command electrical signal to link the first transmission component to the action of the first transmission component, which in turn links the ground lock to open or close synchronously.

[0009] The first transmission component includes: a guide fixing seat connected to the connecting plate;

[0010] The first shaft has one end connected to the connecting plate and the other end protruding from the guide fixing seat;

[0013] The second rocker arm is movably connected to the first shaft;

[0014] A toggle shaft is inserted into the second rocker arm at one end. As the second rocker arm rotates, the other end of the toggle shaft moves along the guide fixing seat, causing the first rocker arm to rotate around the first shaft as the rotation center. The first rocker arm rotates along the guide fixing seat.

[0015] And a first washer, placed on the second rocker arm, positioned between the first shaft and the second rocker arm.

[0016] Furthermore: the guide fixing seat includes: a seat body connected to the connecting plate, used for guiding and limiting the first rocker arm;

[0017] A fixed shaft is connected to the base body;

[0018] The arm body is positioned on the base by the fixed shaft and is used to guide the actuating shaft.

[0019] Furthermore: the second transmission assembly includes an electric drive element connected to the connecting plate;

[0020] The second shaft is connected to the connecting plate and is spaced apart from the electric drive component;

[0021] The first gear is movably connected to the second shaft and is rotated in conjunction with the electric drive component.

[0022] The third rocker arm is disposed on one side of the first gear and between the first gear and the connecting plate. One end of the third rocker arm is movably connected to the second shaft. The third rocker arm is rotated by the first gear and moves in conjunction with the first rocker arm.

[0023] A tension spring is connected between the third rocker arm and the connecting plate;

[0024] A first micro switch is connected to the connecting plate;

[0025] The second micro switch is connected to the connecting plate and is spaced apart from the first micro switch;

[0026] And a contact block, connected to the first gear, for contacting the first micro switch or the second micro switch.

[0027] Furthermore: the electric drive component includes: a motor connected to the connecting plate;

[0028] And a second gear, connected to the motor, meshing with the first gear.

[0029] Furthermore: the first gear has a fan-shaped structure with protruding teeth on its outer edge, and the protruding teeth mesh with the second gear;

[0030] The first gear also has a first protrusion, which is disposed on one side wall of the first gear and is used to actuate the third rocker arm.

[0031] The first gear also has a second protrusion, which is disposed on the other side wall of the first gear;

[0032] The first gear also has a hole at which the contact block is connected.

[0033] Furthermore: the contact block includes: an arc-shaped block;

[0034] And connecting bolts, which pass through the holes, connect the arc-shaped block and the first gear.

[0035] Furthermore, it also includes: a fourth rocker arm, disposed on the other side of the first gear, the fourth rocker arm being movably connected to the second shaft and connected to the ground lock, the fourth rocker arm being rotated in conjunction with the first gear;

[0036] The second torsion spring is sleeved on the second shaft and is disposed between the first gear and the fourth rocker arm, and is connected to the connecting plate and the fourth rocker arm;

[0040] The first transmission assembly includes: a guide fixing seat, a first shaft, a first rocker arm, a first torsion spring, a second rocker arm, a toggle shaft, and a first washer;

[0041] The connecting plate forms a reliable support structure, which is beneficial for setting up the first and second transmission components, and is relatively easy to assemble with the door;

[0042] When the top and bottom locks are opened electrically in sync: After receiving the command signal from the vehicle body, the second transmission component is activated, which in turn drives the first rocker arm to rotate around the first shaft as the rotation center. The first rocker arm rotates along the guide fixed seat, and the first torsion spring rotates to store force. The first rocker arm is then linked with the top and bottom locks to open synchronously.

[0043] When the top and bottom locks are closed electrically in sync: After receiving the vehicle body command signal, the second transmission component moves in the opposite direction, the second transmission component releases the first rocker arm, and under the torque of the first torsion spring, the first rocker arm gradually returns to its original position, and the first rocker arm is linked to the top and bottom locks to close synchronously.

[0044] This overcomes the technical problem of relatively poor transmission synchronization and achieves a relatively good transmission synchronization effect, thus proving its practicality. Attached Figure Description

[0055] To make the content easier to understand, the following detailed description is provided with reference to specific embodiments and accompanying drawings;

[0056] An electrically operated self-priming transmission mechanism solves the technical problem of relatively poor transmission synchronization in related technologies. It can be manufactured and used, achieving a relatively good transmission synchronization effect. The overall concept is as follows:

[0057] Implementation Method

[0058] like Figure 1 , Figure 2 , Figure 9 As shown; an electrically operated self-priming transmission mechanism, comprising:

[0059] Connecting plate 10;

[0060] The first transmission component 20 is connected to the connecting plate 10 and is connected to the ground lock.

[0061] And the second transmission component 30, connected to the connecting plate 10, is activated after receiving the vehicle body command electrical signal, and is used to link the first transmission component 20 to operate, and the first transmission component 20 links the ground lock to open or close synchronously.

[0062] The first transmission assembly 20 includes a guide fixing seat 20-1, which is connected to the connecting plate 10.

[0063] The first shaft 20-2 has one end connected to the connecting plate 10 and the other end protruding from the guide fixing seat 20-1;

[0064] The first rocker arm 20-3 is movably connected to the first shaft 20-2, connected to the ground lock, and is linked by the second transmission component 30.

[0065] The first torsion spring 20-4 is sleeved on the first shaft 20-2 and connected between the first rocker arm 20-3 and the guide fixing seat 20-1;

[0066] The second rocker arm 20-5 is movably connected to the first shaft 20-2;

[0067] The actuating shaft 20-6 is inserted into the second rocker arm 20-5 at one end. As the second rocker arm 20-5 rotates, the other end of the actuating shaft 20-6 moves along the guide fixing seat 20-1, causing the first rocker arm 20-3 to rotate around the first shaft 20-2 as the rotation center. The first rocker arm 20-3 rotates along the guide fixing seat 20-1.

[0068] And the first washer 20-7, which is placed on the second rocker arm 20-5 and positioned between the first shaft 20-2 and the second rocker arm 20-5;

[0069] Specifically, in practice, the connecting plate 10 forms a reliable support structure, which is beneficial for setting up the first transmission assembly 20 and the second transmission assembly 30, and is relatively easy to assemble with the door;

[0070] When the top and bottom locks are opened synchronously by electric means: after receiving the command signal from the vehicle body, the second transmission component 30 is activated, which in turn drives the first rocker arm 20-3 to rotate around the first shaft 20-2 as the rotation center. The first rocker arm 20-3 rotates along the guide fixing seat 20-1, and the first torsion spring 20-4 rotates to store force. The first rocker arm 20-3 is then activated synchronously by the top and bottom locks.

[0071] When the top and bottom locks are closed electrically in sync: After receiving the vehicle body command signal, the second transmission component 30 moves in the opposite direction. The second transmission component 30 releases the first rocker arm 20-3. Under the torque of the first torsion spring 20-4, the first rocker arm 20-3 gradually returns to its original position, and the first rocker arm 20-3 is linked to the top and bottom locks to close synchronously.

[0072] It achieves synchronous electric opening and closing of the top and bottom locks, and the synchronization of the transmission is relatively good;

[0073] Another implementation method:

[0074] like Figure 1 , Figure 2 , Figure 9As shown; in implementation, the guide fixing seat 20-1 includes: a seat body 20-1-1, connected to the connecting plate 10, for guiding and limiting the first rocker arm 20-3; a fixing shaft 20-1-2, connected to the seat body 20-1-1; and an arm body 20-1-3, positioned on the seat body 20-1-1 by the fixing shaft 20-1-2, for guiding the actuating shaft 20-6;

[0075] The base body 20-1-1 is made of plastic and is integrally injection molded. It is connected to the connecting plate 10 by screws. The base body 20-1-1 has an annular boss 20-1-11. The annular boss 20-1-11 surrounds the first shaft 20-2 and is used to guide the first rocker arm 20-3 so that the first rocker arm 20-3 will not wobble when rotating, and the structure has relatively good reliability.

[0076] The fixed shaft 20-1-2 is a stepped shaft that is inserted into the base 20-1-1 and is used to position the arm 20-1-3.

[0077] The arm body 20-1-3 is made of plastic and has an arc-shaped structure, which forms a guide and facilitates the movement of the actuating shaft 20-6. This prevents the second rocker arm 20-5 from wobbling when rotating, resulting in relatively good structural reliability.

[0078] Among them, the first shaft 20-2 is a stepped shaft that is inserted into the connecting plate 10;

[0079] One end of the first rocker arm 20-3 is connected to the upper locking mechanism (e.g., using a zipper or connecting rod as in the prior art), and the other end of the first rocker arm 20-3 is connected to the lower locking mechanism (e.g., using a zipper or connecting rod as in the prior art). The first rocker arm 20-3 has a bending area 20-31 in the middle, which is an arc-shaped structure. When rotating around the annular boss 20-1-11, the annular boss 20-1-11 acts as a guide, preventing the first rocker arm 20-3 from swaying during rotation and ensuring relatively good synchronization when driving the locking mechanism.

[0080] The first torsion spring 20-4 is a common structure in the prior art. One pin of the first torsion spring 20-4 is connected to the first rocker arm 20-3, and the other pin is connected to the seat 20-1-1. The first torsion spring 20-4 is used to generate rotational torque, which is beneficial for the return of the first rocker arm 20-3.

[0081] The second rocker arm 20-5 has a roughly fan-shaped block structure and a through groove 20-51 on it. The through groove 20-51 is used to connect with the actuating shaft 20-6, which makes assembly relatively convenient.

[0082] The actuating shaft 20-6 includes: a round shaft section that is inserted into the through groove 20-51; and a U-shaped block that is connected to one end of the round shaft section and slides along the arm body 20-1-3.

[0083] The first washer 20-7 has a circular structure and is riveted to the first shaft 20-2, which helps to limit the second rocker arm 20-5 and prevents it from falling off when the second rocker arm 20-5 rotates around the first shaft 20-2 as the rotation center.

[0084] The second rocker arm 20-5 is connected to the door handle (for example, the two are connected by a zipper as in the prior art). When the door handle is pulled, the second rocker arm 20-5 rotates around the first shaft 20-2 as the rotation center. The second rocker arm 20-5 is linked to the actuating shaft 20-6 to rotate along the arm body 20-1-3. The U-shaped block on the actuating shaft 20-6 touches the first rocker arm 20-3, and the first rocker arm 20-3 rotates counterclockwise. One end of the first rocker arm 20-3 is linked to the upper locking mechanism to open, and the other end of the first rocker arm 20-3 is linked to the lower locking mechanism to open. When the door handle is released, under the torque of the first torsion spring 20-4, the first rocker arm 20-3 returns to its original position. The first rocker arm 20-3 is linked to the locking mechanism to return to its original position, realizing the manual synchronous opening and closing of the locking mechanism. The synchronization of the transmission is relatively good.

[0085] Another implementation method:

[0086] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown; in implementation, the second transmission assembly 30 includes: an electric drive component 30-1 connected to the connecting plate 10; a second shaft 30-2 connected to the connecting plate 10 and spaced apart from the electric drive component 30-1; a first gear 30-3 movably connected to the second shaft 30-2 and rotated in conjunction with the electric drive component 30-1; and a third rocker arm 30-4 disposed on one side of the first gear 30-3, positioned between the first gear 30-3 and the connecting plate 10, with one end of the third rocker arm 30-4 movably connected to the second shaft 30-2. The third rocker arm 30-4 is rotated in conjunction with the first gear 30-3, and the third rocker arm 30-4 is in conjunction with the first rocker arm 20-3; a tension spring 30-5 is connected between the third rocker arm 30-4 and the connecting plate 10; a first micro switch 30-6 is connected to the connecting plate 10; a second micro switch 30-7 is connected to the connecting plate 10 and is spaced apart from the first micro switch 30-6; and a contact block 30-8 is connected to the first gear 30-3 and is used to contact the first micro switch 30-6 or the second micro switch 30-7.

[0087] The electric drive component 30-1 includes: a motor 30-1-1 connected to the connecting plate 10; and a second gear 30-1-2 connected to the motor 30-1-1 and meshing with the first gear 30-3.

[0088] The motor 30-1-1 is a commonly used structure in the prior art, used to generate rotational driving force. Those skilled in the art can directly and without doubt know how to set it up after seeing the disclosed content, without needing to expend creative labor or conduct excessive experiments.

[0089] The second gear 30-1-2 is a spur gear, connected to the drive shaft of the motor 30-1-1, and rotated in conjunction with the motor 30-1-1. The second gear 30-1-2 also meshes with the first gear 30-3 to drive the first gear 30-3 to rotate.

[0090] Among them, the second axis 30-2 is a stepped axis;

[0091] The first gear 30-3 has a fan-shaped structure and a protruding tooth 30-3-1 on its outer edge, which meshes with the second gear 30-1-2.

[0092] The first gear 30-3 also has a first protrusion 30-3-2, which is disposed on one side wall of the first gear 30-3 and is used to actuate the third rocker arm 30-4.

[0093] The first gear 30-3 also has a second protrusion 30-3-3, which is disposed on the other side wall of the first gear 30-3;

[0094] The first gear 30-3 also has a hole 30-3-4, at which the contact block 30-8 is connected;

[0095] The first protrusion 30-3-2 is provided to facilitate the movement of the third rocker arm 30-4;

[0096] The second protrusion 30-3-3 is provided to facilitate the movement of the fourth rocker arm 30-9;

[0097] The third rocker arm 30-4 has an arc-shaped structure. One end is movably connected to the second shaft 30-2, and the other end has a first bent arm 30-41 and a second bent arm 30-42. The first bent arm 30-41 is used to contact the first rocker arm 20-3 and link the first rocker arm 20-3. The second bent arm 30-42 is used to connect one end of the tension spring 30-5.

[0098] Among them, the tension spring 30-5 is a commonly used structure in the prior art, which is used to generate tension force so that when the third rocker arm 30-4 is rotated in conjunction, it can move evenly and will not knock the first rocker arm 20-3, thus reducing noise and having relatively good structural reliability.

[0099] Among them, the first micro switch 30-6 and the second micro switch 30-7 are commonly used structures in the prior art;

[0100] When contact block 30-8 contacts the first micro switch 30-6, motor 30-1-1 stops operating, and electric opening is completed.

[0101] When contact block 30-8 contacts the second micro switch 30-7, motor 30-1-1 stops operating, and electric closing is completed.

[0102] The first micro switch 30-6 and the second micro switch 30-7 are electrically connected to the motor 30-1-1, which is common knowledge.

[0103] Those skilled in the art, upon seeing the disclosed content, can directly and without doubt know how to set the first micro switch 30-6 and the second micro switch 30-7 without needing to expend creative effort or conduct excessive experimentation.

[0104] The contact block 30-8 includes: an arc-shaped block 30-8-1; and a connecting bolt 30-8-2, which passes through the hole 30-3-4 to connect the arc-shaped block 30-8-1 and the first gear 30-3.

[0105] The contact block 30-8 is connected to the first gear 30-3, which facilitates the contact between the arc-shaped block 30-8-1 and the first micro switch 30-6 or the second micro switch 30-7.

[0106] The system includes a second transmission component 30. When the ground lock is opened synchronously and electrically: upon receiving a vehicle body command (the vehicle body command refers to the command of the Body Control Module (BCM), which is common knowledge), the motor 30-1-1 activates, which in turn rotates the first gear 30-3. The first gear 30-3 in turn rotates the third rocker arm 30-4. The third rocker arm 30-4 in turn rotates the first rocker arm 20-3 around the first shaft 20-2 as the rotation center. The first rocker arm 20-3 rotates along the guide fixing seat 20-1. The first torsion spring 20-4 rotates and stores power, and the first rocker arm 20-3 in turn opens synchronously with the ground lock.

[0107] When the top and bottom locks are closed synchronously and electrically: After receiving the vehicle body command signal, the motor 30-1-1 moves in the opposite direction, which drives the first gear 30-3 to rotate. The first gear 30-3 drives the third rocker arm 30-4 to rotate. The third rocker arm 30-4 releases the first rocker arm 20-3. Under the torque of the first torsion spring 20-4, the first rocker arm 20-3 gradually returns to its original position, and the first rocker arm 20-3 drives the top and bottom locks to close synchronously.

[0108] It also includes: a fourth rocker arm 30-9, which is disposed on the other side of the first gear 30-3. The fourth rocker arm 30-9 is movably connected to the second shaft 30-2 and connected to the ground lock. The fourth rocker arm 30-9 is rotated in conjunction with the first gear 30-3.

[0109] The second torsion spring 30-10 is sleeved on the second shaft 30-2 and is disposed between the first gear 30-3 and the fourth rocker arm 30-9, and is connected to the connecting plate 10 and the fourth rocker arm 30-9;

[0110] And the second washer 30-11, connected to the second shaft 30-2, limits the fourth rocker arm 30-9;

[0111] The fourth rocker arm 30-9 is a plate-shaped structure, with one end connected to the upper locking mechanism (for example, the two are connected by a zipper or linkage as in the prior art), and the other end connected to the lower locking mechanism (for example, the two are connected by a zipper or linkage as in the prior art).

[0112] The second torsion spring 30-10 is a commonly used structure in the prior art. One pin is connected to the fourth rocker arm 30-9, and the other pin is connected to the connecting plate 10, so that when the fourth rocker arm 30-9 is linked by the first gear 30-3, it can rotate evenly, with a relatively stable speed and relatively good structural reliability.

[0113] The second washer 30-11 is an annular washer, which is riveted to the second shaft 30-2. This helps to limit the fourth rocker arm 30-9 and prevent the fourth rocker arm 30-9 from falling off.

[0114] Self-priming function: When the top and bottom locks are closed electrically in sync, if the closure is not tight, the body control module (BCM) sends an electrical signal to the motor 30-1-1 on the second transmission assembly 30. The motor 30-1-1 is activated, which in turn drives the first gear 30-3 to rotate. The first gear 30-3 in turn drives the fourth rocker arm 30-9 to rotate. The fourth rocker arm 30-9 in turn further drives the top and bottom locks to perform self-priming closure.
