Description
Technical Field
[0001] The utility model belongs to the technical field of automobile door locks, and in particular relates to a novel self-priming driving mechanism for automobile door locks. Background Art
[0002] The self-closing function of a car door means that when the car door is not completely closed (in a half-locked state), the door lock can be automatically sucked into the fully locked position, thereby ensuring that the door is in a safely closed state; currently, most car doors on the market are equipped with ordinary mechanical locks, and the original self-closing locks are expensive, which makes many customers reluctant to buy them.
[0003] To solve this problem, the patent with application number 2019215951402 proposes a self-closing drive mechanism for a car door lock, which is installed on the mechanical lock of the car door through a support. The first ratchet on the support and the second ratchet on the mechanical lock simultaneously engage the lock on the car door to make the car door enter a semi-locked state, and then the first ratchet is driven to rotate by the driving component to force the mechanical lock on the car door to move toward the lock on the car door, so that the car door enters a fully locked state.
[0004] Although the above solution solves the problem of adding a self-priming function to a mechanical lock, the overall structure is relatively complex. Not only is the cost high, but it also requires a large installation space, making it difficult to install on a smaller mechanical lock and having poor usability. Utility Model Content

DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.
[0033] See attached Figure 1 -Attached Figure 8 A novel self-closing driving mechanism for a car door lock includes a fixed plate 1 and a driving member 3; the fixed plate 1 is installed on the mechanical lock 2, and a first ratchet 11 is provided on the fixed plate 1, the first ratchet 11 is rotatably connected to the fixed plate 1 and corresponds to the second ratchet 21 of the mechanical lock 2; the driving member 3 includes a cable 31 and an elastic member 32, the cable 31 is installed on the fixed plate 1 and connected to the first ratchet 11, so as to drive the first ratchet 11 to drive the mechanical lock 2 to move toward the door lock; the two ends of the elastic member 32 are respectively connected to the fixed plate 1 and the first ratchet 11, so as to drive the first ratchet 11 to reset.
[0034] Specifically, the mechanical lock 2 is arranged on a movable door (not shown in the figure), and the door lock catch (not shown in the figure) is installed on the vehicle body (not shown in the figure); when the door is closed under the action of external force, the door lock catch will approach the mechanical lock 2 and contact the first ratchet catch 11 and the second ratchet catch 21, so as to drive the first ratchet catch 11 and the second ratchet catch 21 to initially engage with the door lock catch, so that the door enters a semi-locked state;
[0035] In the semi-locked state, the contraction cable 31 drives the first ratchet buckle 11 to rotate, and the first ratchet buckle 11 applies pressure to the door lock buckle, forcing the mechanical lock 2 to automatically move toward the door lock buckle until the first ratchet buckle 11 and the second ratchet buckle 21 are completely engaged with the door lock buckle, so that the door enters the fully locked state, and the elastic member 32 is in a deformation energy storage state;
[0036] In the fully locked state, if the cable 31 is released, the elastic member 32 will release energy to recover and have a tendency to drive the first ratchet buckle 11 to reset. At this time, if the user controls the second ratchet buckle 21 on the mechanical lock 2 to disengage from the door buckle, then during the process of opening the door, the first ratchet buckle 11 will fit the door buckle and automatically reset with the door buckle, thereby releasing the restriction on the door buckle and ensuring that the door can be opened smoothly.
[0037] In summary, the utility model designs a fixing plate 1 for connecting the mechanical lock 2, designs a cable 31 on the fixing plate 1 for driving the first ratchet 11 to rotate, so as to drive the mechanical lock 2 to approach the door lock to realize automatic closing of the door, and designs an elastic member 32 on the fixing plate 1 for driving the first ratchet 11 to reset when the door is opened and the cable 31 is released, so as to release the restriction on the door lock and facilitate the normal opening of the door. The design of the elastic member 32 can also make the first ratchet 11 keep in contact with the door lock, so as to reduce noise and reduce the possibility of damage caused by collision between the two. Compared with the prior art, the self-closing drive mechanism only needs to set the fixing plate 1, the first ratchet 11, the cable 31 and the elastic member 32 to make the door have the self-closing function. Therefore, not only fewer accessories are used, the overall structure is simple, the cost is low, and the structure is compact, which can reduce the occupied space and facilitate installation on a variety of mechanical locks 2, thereby improving usability.
[0038] It should be noted that an actuator can be installed at the head end of the cable 31 to control the contraction and release of the cable 31, and a corresponding sensor can be set on the fixing plate 1 to monitor the position of the door lock, so as to send instructions to the actuator to control the action timing of the cable 31; since the cable 31, the actuator and the sensor are relatively conventional in the automotive field, and the technology for the coordination of the three is also relatively existing, the specific structure and working principle thereof are not further elaborated in the present utility model.
[0039] See attached Figure 5 -Attached Figure 6 A receiving cavity 10 opening outward is provided on the fixing plate 1, and a notch 101 is provided on the bottom wall of the receiving cavity 10. The notch 101 is designed to correspond to the lock hole 20 on the mechanical lock 2 for the door lock buckle to pass through; the first ratchet buckle 11 is located in the receiving cavity 10, and the tail end of the cable 31 extends into the receiving cavity 10 and is connected to the first ratchet buckle 11.
[0040] Specifically, when the door is closed under the action of external force, the door lock buckle will enter the notch 101 and drive the first ratchet buckle 11 and the second ratchet buckle 21, and the first ratchet buckle 11 and the second ratchet buckle 21 are initially engaged with the door lock buckle, so that the door enters a semi-locked state; at this time, the retracted cable 31 drives the first ratchet buckle 11 to rotate, and the first ratchet buckle 11 applies pressure to the door lock buckle, forcing the mechanical lock 2 to automatically move toward the door lock buckle, until the first ratchet buckle 11 and the second ratchet buckle 21 are completely engaged with the door lock buckle, and the door enters a fully locked state;
[0041] In the fully locked state, if the cable 31 is released, the elastic member 32 will release energy to recover and have a tendency to drive the first ratchet 11 to reset. At this time, if the user controls the second ratchet 21 on the mechanical lock 2 to disengage from the door lock, then during the process of opening the door, the first ratchet 11 will fit the door lock and automatically reset with the door lock until the door lock is disengaged from the second ratchet 21, the first ratchet 11 and the notch 101 in turn.
[0042] Among them, the design of the accommodating cavity 10 can make the tail ends of the first ratchet 11 and the cable 31 hidden in the fixing plate 1, thereby effectively reducing the space occupied by the first ratchet 11 and the cable 31 to reduce the overall thickness and make the structure more compact; in addition, it can also provide protection for the tail ends of the first ratchet 11 and the cable 31 to prevent the two from being damaged by contact with external debris, thereby extending the overall service life.
[0043] See attached Figure 5 -Attached Figure 7 In order to facilitate the assembly and disassembly of the first ratchet buckle 11, the utility model also includes a fastening bolt 4, a rotating column 102 is provided on the bottom wall of the accommodating cavity 10 of the fixing plate 1, and a rotating hole 110 is provided on the first ratchet buckle 11, and the rotating hole 110 is rotatably matched with the rotating column 102; the fastening bolt 4 abuts against the first ratchet buckle 11, and one end of the fastening bolt 4 is threadedly connected with the rotating column 102, so that the first ratchet buckle 11 can be rotatably installed on the fixing plate 1.
[0044] Specifically, during installation, the first ratchet 11 is sleeved on the rotating column 102 through the rotating hole 110, and then the fastening bolt 4 is tightened on the rotating column 102. Under the restriction of the fastening bolt 4, the first ratchet 11 can only rotate around the rotating column 102 and cannot be separated from the rotating column 102; during disassembly, the fastening bolt 4 is directly unscrewed from the rotating column 102, and the first ratchet 11 can be removed from the rotating column 102.
[0045] It should be noted that, in addition to the above-mentioned installation method, the first ratchet buckle 11 can also be rotatably connected to the fixing plate 1 in other ways, which is not limited in the present utility model.
[0046] See attached Figure 5 -Attached Figure 7 A movable groove 103 is also provided on the bottom wall of the accommodating cavity 10; an end 111 is provided on the first ratchet buckle 11, and the end 111 is placed in the movable groove 103 and can move along the movable groove 103 as the first ratchet buckle 11 rotates; the tail end of the cable 31 extends into the movable groove 103 and is connected to the end 111; the coordinated use of the end 111 and the movable groove 103 can not only limit the swing amplitude of the first ratchet buckle 11, but also further improve the rotation stability of the first ratchet buckle 11.
[0047] See attached Figure 5 -Attached Figure 7 A bayonet 1110 is provided on the end 111, and a clamping block 310 is provided at the tail end of the cable 31. The clamping block 310 and the bayonet 1110 are engaged with each other. This design allows the cable 31 to be detachably connected to the end 111, thereby facilitating the disassembly and assembly of the cable 31 and the first ratchet buckle 11, and when the cable 31 or the first ratchet buckle 11 is damaged, they can be replaced separately, thereby improving the convenience of maintenance.
[0048] See attached Figure 5 -Attached Figure 7 A mounting opening 1030 connected to the outside is provided on the bottom wall of the movable groove 103 . The elastic member 32 is located at the movable groove 103 and corresponds to the mounting opening 1030 , so that the elastic member 32 can be disassembled and replaced through the mounting opening 1030 .
[0049] Specifically, the user can observe the elastic member 32 through the installation opening 1030 to determine whether the elastic member 32 is damaged; when the elastic member 32 is damaged, the elastic member 32 can be directly disassembled and assembled through the installation opening 1030 without additionally disassembling the fixing plate 1, so as to further improve the maintenance convenience.
[0050] Furthermore, the elastic member 32 can be a rubber column, an elastic plastic sleeve, a spring, etc. Due to the variety of related accessories, the present invention does not impose any restrictions on this; for ease of understanding, the elastic member 32 in this embodiment is a spring, which has a low cost and strong deformation and recovery capabilities, and can well drive the first ratchet buckle 11 to reset.
[0051] See attached Figure 3 -Attached Figure 5 The fixing plate 1 can be connected and fixed to the mechanical lock 2 by means of buckling, bonding, welding, etc., and there is no restriction on this in the utility model. For the convenience of understanding, in this embodiment, a fixing column 12 is provided on the fixing plate 1, and a stepped hole 120 is opened on the fixing column 12 for a bolt (not shown in the figure) to pass through, and a threaded hole 22 corresponding to the stepped hole 120 is provided on the mechanical lock 2.
[0052] Specifically, during installation, the bolt is inserted into the stepped hole 120 and screwed into the threaded hole 22 , so that the fixing plate 1 can be installed on the mechanical lock 2 ; during disassembly, the bolt is screwed out of the threaded hole 22 .
[0053] See attached Figure 7 -Attached Figure 8 The utility model further includes a rubber sleeve 5, which is mounted on the first ratchet buckle 11 and is designed to correspond to the door lock buckle to reduce the sound generated when the first ratchet buckle 11 contacts the door lock buckle.
[0054] Specifically, when the vehicle door is closed under the action of external force, the vehicle door lock buckle will approach the mechanical lock 2 and contact the first ratchet buckle 11. At this time, the rubber sleeve 5 can prevent the first ratchet buckle 11 from rigidly colliding with the vehicle door lock buckle; similarly, when the cable 31 is released, the first ratchet buckle 11 remains in contact with the vehicle door lock buckle under the action of the elastic member 32, and the rubber sleeve 5 can prevent the first ratchet buckle 11 and the elastic member 32 from rubbing against each other during the process of opening the vehicle door; therefore, the design of the rubber sleeve 5 can reduce the sound generated when the first ratchet buckle 11 and the elastic member 32 come into contact with each other while avoiding damage to both, thereby extending the service life of the first ratchet buckle 11 and the vehicle door lock buckle.
[0055] It should be noted that the rubber sleeve 5 can be fixed to the first ratchet buckle 11 by bonding, clamping, etc., or directly fixed by bolts. Due to the variety of methods, this is not limited in the present invention.
[0056] Furthermore, the rubber sleeve 5 is made of rubber material so that it can reduce the sound and have good wear resistance.
[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
