Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a vehicle door lock. Background Art

[0002] The door lock is an important component of the vehicle, which is used to lock or unlock the door relative to the vehicle body. Traditional door locks are locked and unlocked manually. With the development of vehicle intelligence and electrification, the functions of door locks have become more abundant. For example, for door locking, when the door is closed to a predetermined angle, the door lock can automatically close to completely close the door; when unlocking is required, the door lock can be released electrically without the user unlocking it. Furthermore, some door locks are also equipped with an ice-breaking function to solve the problem that the door is frozen in cold weather or the door cannot be opened after being released electrically when the vehicle is parked on a slope.

[0003] In this case, corresponding components are added to the door lock for different functions. For example, for the self-priming function, a self-priming rod needs to be provided. For the ice-breaking function, an ice-breaking rod is provided. Considering the specific structure of the door lock, the self-priming rod and the ice-breaking rod have specific shapes and need to be installed on the door lock. Therefore, the addition of these functions leads to an increase in the number of door lock components, which increases the complexity of the door lock and is not conducive to manufacturing and assembly.

[0028] In the following, terms such as "first", "second", etc. are used to describe the elements of the present application. These terms are only used to distinguish the various elements, and are not used to limit the nature, order or number of these elements. The terms "including" and "having" are used to express an open-ended inclusive meaning, and mean that there may be additional elements / components in addition to the listed elements / components.

[0029] Figure 1 The front view of the vehicle door lock of the utility model is shown. The vehicle door lock includes two parts that can be locked or unlocked with each other, and the two parts are respectively located on the vehicle door and the vehicle body. As an example, a lock catch 9 can be fixedly arranged on the vehicle door, and the lock catch 9 can be engaged or disengaged with the ratchet 6, so as to achieve locking or unlocking of the vehicle door relative to the vehicle body. The ratchet 6 can rotate around the ratchet shaft 6, and can be engaged or disengaged with the lock catch 9 during the rotation process. The vehicle door lock is also provided with a pawl 10 that cooperates with the ratchet 6, and the pawl 10 can rotate around the pawl shaft 11,

[0030] In order to realize the rotation of the ratchet 6, a driving component 1 is provided. The driving component 1 itself is connected to a power source such as a motor, so that it can rotate around the rotation axis 2 when the power source rotates. The driving component 1 is provided with a functional component, which can contact the ratchet 6 and drive the ratchet 6 to rotate. When the driving component 1 rotates, it can drive the functional component on it to rotate, thereby driving the ratchet 6 to rotate. It should be understood that although Figure 1Only the driving component 1 is shown in the figure, but the driving component 1 can be directly or indirectly connected to the power source. For example, a multi-stage transmission device can be arranged between the driving component 1 and the power source, for example, a plurality of gear pairs can be arranged.

[0031] The functional components on the driving component 1 include a self-priming device 3 located on one side. Specifically, the self-priming device 3 is installed on the driving component 1 by means of a fixing device 4 provided on the driving component 1, so that the self-priming device 3 can be fixed relative to the driving component 1. In order to cooperate with the self-priming device 3, a first feature 8 is provided on the ratchet 6. Specifically, the first feature 8 has a base and an angular portion located on one side of the base, and is engaged with the self-priming device 3 via the angular portion. Correspondingly, a concave portion matching the shape of the angular portion is provided on the self-priming device 3. Thus, in Figure 1 In the embodiment, when the driving component 1 rotates in the counterclockwise direction, the self-priming device 3 rotates accordingly, and then drives the ratchet 6 to rotate through the first feature 8. As a result, the concave portion on the ratchet 6 engages with the lock buckle 9 to achieve locking.

[0032] Figure 2 FIG. 1 shows a three-dimensional view of the driving component in the door lock of the utility model. Figure 2 As can be seen in the figure, the driving component 1 is also provided with an ice-breaking device 5 which is preferably formed integrally with the driving component 1. Specifically, the ice-breaking device 3 is a columnar structure parallel to the rotating shaft 2. Figure 2 The ice-breaking device 5 is shown as a cylindrical structure. In addition, the ice-breaking device 5 can also adopt a cam or other known feasible structures. Of course, the driving component 1 and the ice-breaking device 5 can also be manufactured separately and then installed together. For example, a recessed portion is provided on the driving component 1, and the ice-breaking device 5 can be inserted into the recessed portion.

[0033] Corresponding to the ice-breaking device 5, the ratchet 6 is provided with a second feature 12 that cooperates with the ice-breaking device 5. When the ice-breaking device 5 adopts a cylindrical structure, the second feature 12 has a straight edge of a certain length. Figure 1 In the embodiment, when the driving component 1 rotates in the clockwise direction, the ice-breaking device 5 rotates accordingly, and after contacting the second feature 12, the ratchet wheel 6 rotates, thereby realizing the ice-breaking function.

[0034] The above is a detailed description of the structure of the utility model. Figures 3 to 5 The working process of the vehicle door lock of the present utility model is described.

[0035] Figure 3 FIG. 2 shows a view of the vehicle door lock of the present invention in the first position. In this position, the vehicle door is in a closed state and the driving component 1 is in its initial position. Figure 3It can be seen from the figure that the lock buckle 9 is completely located in the concave part of the ratchet 6, and the self-priming device 3 and the ice-breaking device 5 are not engaged with the ratchet 6 and keep a certain distance from the ratchet 6.

[0036] Figure 4 The view of the vehicle door lock of the utility model in the first process is shown. In the first process, the vehicle door lock turns from the first position to the open position, and the vehicle door correspondingly changes from the closed state to the open state. Under normal circumstances, at the first position, when the ratchet and the pawl are disengaged, the ratchet and the lock catch will separate due to the sealing force of the vehicle door, and the vehicle door will open. However, in the case where the vehicle door is frozen relative to the vehicle body or the vehicle is on a road with a certain slope and the vehicle door is subject to the effect of gravity, the vehicle door cannot be opened. At this time, the ice-breaking function of the vehicle door lock needs to be executed. Specifically, from Figure 4 It can be seen that at this time, the driving component 1 rotates in the clockwise direction, and the ice-breaking device 5 thereon moves downward, and after contacting the second feature 12 of the ratchet 6, drives the ratchet 6 to rotate in the clockwise direction, so that the ratchet 6 abuts against the lock catch 9 to open the door lock, and then drives the door to open. Therefore, the first process can also be called the ice-breaking process.

[0037] Figure 5 FIG. 2 shows a view of the vehicle door lock of the present invention in the second process. In this process, when the vehicle door is closed to a predetermined angle, the lock catch 9 partially contacts the ratchet 6, and the driving component 1 moves along the Figure 5 As shown, the self-priming device 3 rotates counterclockwise, and when the self-priming device 3 contacts the first feature 8 on the ratchet 6, as the driving component 1 continues to rotate, the self-priming device 3 drives the first feature 8 and then the ratchet 6 to rotate counterclockwise, so that the ratchet 6 is fully engaged with the lock catch 8, and the ratchet and the pawl are also engaged, thereby completing the locking of the door lock. At this time, the driving component 1 stops rotating and returns to the initial position.

[0038] From the above, it can be seen that in the present utility model, the ice-breaking device and the driving component are formed in a one-piece, especially integrally formed manner, and the ice-breaking device is engaged with the ratchet, thereby achieving the same function while reducing the number of parts that need to be assembled during manufacturing, thereby reducing the overall complexity and correspondingly reducing the cost.

[0039] For those skilled in the art, various modifications and variations may be made to the embodiments disclosed above without departing from the scope or spirit of the utility model. Other embodiments of the utility model will be apparent to those skilled in the art from the practice of the utility model disclosed in this specification. This specification and the examples disclosed therein should be considered to be illustrative only, and the true scope of the utility model is specified by the appended claims and their equivalents.
