[0034] The present application proposes a door lock structure 10, which can effectively reduce the rotation speed of the lock plate 2 through the damper 3 when the lock plate 2 locks or unlocks the lock buckle 102, thereby reducing the noise generated when the lock plate 2 contacts other structures during rotation. In addition, the damper 3 is more reliable than the vibration-damping gasket and is not prone to failure due to material reasons. Therefore, the door lock structure 10 can be reliably reduced in vibration and noise, thereby improving the user experience.
[0035] Reference below Figures 1 - 6 A door lock structure 10 according to an embodiment of the present invention is described.
[0036] like Figures 1 - 6As shown, the door lock structure 10 according to an embodiment of the present utility model includes a locking assembly 101 and a latch 102. The locking assembly 101 includes a lock plate 2 and a damper 3. The lock plate 2 is adapted to rotate about a first rotation axis. In the rotation direction, the lock plate 2 has a locking position and an unlocking position. In the locking position, the lock plate 2 is used to lock the latch 102. In the unlocking position, the lock plate 2 is used to unlock the latch 102. The damper 3 is drivingly connected to the lock plate 2 and is used to impede the rotation of the lock plate 2.
[0037] Exemplarily, the door lock structure 10 is applied to a vehicle. The vehicle includes a vehicle body 30 and a vehicle door 20. The latch 102 is installed on the vehicle body 30, and the locking assembly 101 is installed on the vehicle door 20. During the closing process of the vehicle door 20, as the vehicle door 20 rotates, the lock plate 2 contacts the latch 102. The lock plate 2 has a door lock fish mouth 22. The latch 102 abuts against the lock plate 2, causing the lock plate 2 to rotate about the first rotation axis, so that the lock plate 2 rotates from the unlocking position to the locking position. After the lock plate 2 rotates to the locking position, the lock plate 2 can be fixed, so that the latch 102 is stably locked with the lock plate 2, and further the vehicle door 20 cannot be opened. When the vehicle door 20 needs to be opened, as the vehicle door 20 rotates, the latch 102 abuts against the lock plate 2, causing the lock plate 2 to rotate about the first rotation axis, so that the lock plate 2 rotates from the locking position to the unlocking position. Then, as the vehicle door 20 continues to rotate, the latch 102 leaves the lock plate 2 from the door lock fish mouth 22 of the lock plate 2. At this time, the latch 102 and the lock plate 2 are unlocked from each other.
[0038] In the above example, the locking assembly 101 is generally installed on the side of the vehicle door 20 away from the rotation axis of the vehicle door 20, so that the locking assembly 101 or the lock plate 2 has a relatively high rotation speed, and the lock plate 2 can rotate about the first rotation axis. For example, when the vehicle door 20 is closed, when the lock plate 2 rotates from the unlocking position towards the locking position, the end position of the rotation often exceeds the locking position, and then the lock plate 2 will reverse and rotate back a certain angle to the locking position. During this process, the lock plate 2 is likely to collide with other structures inside the vehicle door 20, and even when the lock plate 2 reversely rotates, it is likely to collide with the latch 102, resulting in vibration and noise of the door lock structure 10. However, in the present application, by providing the damper 3, the rotation speed of the lock plate 2 can be reduced when the lock plate 2 rotates, so that the lock plate 2 rotates at a slow speed. This not only does not affect the opening and closing of the vehicle door 20, but also can reduce the force of collision between the lock plate 2 and other structures inside the vehicle door 20, thereby reducing the vibration and noise generated by the door lock structure 10 and improving the user experience.
[0039] In addition, the damper 3 of the present utility model is drivingly connected to the lock plate 2, that is, the damper 3 can act independently, is not easily damaged, and can effectively consume the acting force transmitted from the lock plate 2, so as to effectively maintain the vibration reduction and noise reduction ability of the door lock structure 10.
[0040] In the above example, the door lock structure 10 can also be applied to other structures that need to be locked, not just vehicles, and this application does not impose any restrictions on this.
[0041] Therefore, according to the door lock structure 10 of the embodiment of the utility model, by setting the damper 3 and making the damper 3 transmission connected with the lock plate 2, the damper 3 can act independently, is not easily damaged, and can effectively consume the force transmitted from the lock plate 2, thereby effectively maintaining the vibration reduction and noise reduction capabilities of the door lock structure 10 and improving the user experience.
[0042] In some embodiments of the utility model, the lock plate 2 has a first rotational matching portion extending around the first rotation axis in the circumferential direction, and the damper 3 has a second rotational matching portion that is transmission-matched with the first rotational matching portion. That is, when the lock plate 2 rotates, the lock plate 2 can transmit the rotational force to the second rotational matching portion through the first rotational matching portion, and the second rotational matching portion transmits the rotational force to the damping structure on the damper 3. The damping structure hinders the second rotational matching portion and transmits the resistance to the lock plate 2 in a sequential linkage manner, thereby reducing the rotation speed of the lock plate 2.
[0043] Exemplarily, the first rotating matching part has an arcuate surface extending around the first rotating axis, and the second rotating matching part is a rotating wheel abutting the arcuate surface. Thus, when the lock plate 2 drives the first rotating matching part to rotate, the arcuate surface can drive the rotating wheel to rotate, and the rotating wheel transmits the rotational force to the damping structure on the damper 3. The damping structure hinders the rotating wheel and transmits the resistance to the lock plate 2 in a sequential linkage manner, thereby reducing the rotation speed of the lock plate 2.
[0044] In some embodiments of the present invention, Figures 1 - 6 As shown, the first rotational matching part includes a sector gear 21, and the second rotational matching part includes a circular gear 31 meshing with the sector gear 21. That is to say, the door lock structure 10 of the present invention can effectively transmit the force between the lock plate 2 and the damper 3 by means of the meshing of the sector gear 21 and the circular gear 31, has good stability, and generates less noise, which can better improve the vibration reduction and noise reduction effects of the door lock structure 10.
[0045] In some embodiments of the present invention, Figures 1 - 6 As shown, the diameter of the sector gear 21 is larger than the diameter of the circular gear 31. Therefore, when the tooth plate rotates, the rotation speed of the tooth plate is lower than the rotation speed of the circular gear 31, so that the circular gear 31 can better hinder the rotation of the tooth plate through the damper 3, and the rotation of the tooth plate can be more stable when hindered by the damper 3, which can further reduce vibration and noise.
[0046] In some embodiments of the present invention, Figures 1 - 6As shown, the door lock structure 10 further includes: a first elastic member 51 and a movable limiting member 4. The first elastic member 51 is connected to the lock plate 2 and is used to keep the lock plate 2 in the unlocked position. The limiting member 4 has a limiting position and an avoidance position in the moving direction. In the limiting position, the limiting member 4 is used to limit the lock plate 2 in the locked position. In the avoidance position, the limiting member 4 allows the lock plate 2 to move between the unlocked position and the locked position.
[0047] That is to say, when the lock plate 2 rotates from the unlocked position to the locked position, the limiting member 4 can limit the position of the lock plate 2, so that the lock plate 2 is kept in the locked position, and further the lock plate 2 and the lock catch 102 are stably locked, so that the door 20 cannot be opened, with simple structure, high reliability and good stability. When it is necessary to unlock the lock plate 2 and the lock catch 102, the limiting member 4 can be moved from the limiting position to the avoidance position by an electric or manual method. At this time, under the action of the first elastic member 51, the lock plate 2 can rotate from the locked position to the unlocked position, so that the lock plate 2 and the lock catch 102 are separated, with simple structure, and both locking and unlocking are relatively convenient.
[0048] Exemplarily, the first elastic member 51 can be a torsion spring or other elastic structures, which is not limited in this application. When the first elastic member 51 is a torsion spring, the first elastic member 51 can be sleeved on the first rotating shaft 61.
[0049] In some embodiments of the present invention, the limiting member 4 rotates around the second rotation axis. That is to say, the limiting member 4 can move in a rotational manner. Compared with the limiting member 4 that moves in a straight line, the rotatable limiting member 4 has a smaller movement range, which is beneficial to reducing the size of the door lock structure 10, and thus is beneficial to the miniaturized design of the door lock structure 10.
[0050] In some embodiments of the present invention, the first rotation axis and the second rotation axis are parallel. Thus, the limiting member 4 can reciprocally rotate between the limiting position and the avoidance position better, and the rotation plane of the limiting member 4 and the rotation plane of the lock plate 2 are parallel or even coplanar, which can better reduce the thickness of the locking assembly 101 in the direction of the first rotation axis, and thus is beneficial to the miniaturized design of the locking assembly 101.
[0051] In some embodiments of the present invention, such as Figures 1 - 6As shown, the locking assembly 101 further includes a second elastic member 52, which is connected to the limiting member 4 and is used to keep the limiting member 4 in the limiting position. Therefore, when the lock plate 2 rotates from the unlocking position to the locking position, the lock plate 2 can drive the limiting member 4 to make the limiting member 4 rotate to overcome the elastic force of the second elastic member 52, so that the limiting member 4 can rotate to the avoidance position. When the lock plate 2 passes over the limiting member 4, the limiting member 4 returns to the limiting position under the elastic force of the second elastic member 52, thereby limiting the rotation of the lock plate 2, so that the lock plate 2 is stably kept in the locked position. When the lock plate 2 needs to be moved from the locking position to the unlocking position, it is only necessary to move the limiting member 4 from the limiting position to the avoidance position by electric or manual means. The structure is simple and the operation is convenient.
[0052] Exemplarily, the second elastic member 52 is a torsion spring, and the torsion spring can be sleeved on the second rotating shaft 62 .
[0053] In some embodiments of the present invention, Figures 1 - 6 As shown, the damper 3 is arranged on the side of the lock plate 2 away from the limiter 4, whereby the independently movable damper 3 and the limiter 4 are not prone to interference, so that they can each operate stably with high reliability and good stability.
[0054] Exemplarily, the lock plate 2 , the damper 3 and the limit member 4 may be directly mounted on the vehicle door 20 , or may be mounted in the housing 6 , and this application does not impose any limitation thereto.
[0055] In some embodiments of the present invention, Figures 1 - 6 As shown, the locking assembly 101 further includes a housing 6, the lock plate 2 and the damper 3 are both installed in the housing 6, the housing 6 has a lock hole 63, when the lock plate 2 is in the unlocked position, the door lock fish mouth 22 of the lock plate 2 is opposite to the lock hole 63, wherein one of the housing 6 and the lock plate 2 is provided with a first rotating shaft 61, and the other is provided with a first shaft hole 23 that is rotatably matched with the first rotating shaft 61. Exemplarily, the housing 6 is provided with a first rotating shaft 61, and the lock plate 2 is provided with a first shaft hole 23 that is rotatably matched with the first rotating shaft 61.
[0056] By installing the lock plate 2 and the damper 3 in the housing 6, foreign objects are not easily introduced into the transmission connection position between the lock plate 2 and the damper 3, so that the transmission between the lock plate 2 and the damper 3 can be well ensured. In addition, the housing 6 can also well protect the lock plate 2 and the damper 3 to prevent the lock plate 2 and the damper 3 from being damaged. When the lock catch 102 needs to cooperate with the locking assembly 101, the lock catch 102 can enter the door lock fish mouth 22 from the lock hole 63, and when unlocking, the lock catch 102 can also leave the door lock fish mouth 22 from the lock hole 63.
[0057] In some embodiments of the present invention, Figures 1 - 6As shown, the locking assembly 101 further includes a stopper 4, which is rotatably disposed in the housing 6, and is used to limit the lock plate 2 to a locked position, and a second rotating shaft 62 is disposed on one of the housing 6 and the stopper 4, and a second shaft hole 41 that cooperates with the second rotating shaft 62 is disposed on the other. Exemplarily, the housing 6 is provided with the second rotating shaft 62, and the stopper 4 is provided with the second shaft hole 41 that rotatably cooperates with the second rotating shaft 62.
[0058] The utility model also provides a vehicle having the door lock structure 10 of the above embodiment.
[0059] like Figures 1 - 6 As shown, the vehicle according to the present utility model includes a vehicle body 30, a vehicle door 20 and a door lock structure 10, wherein the door lock structure 10 includes: a locking assembly 101 and a lock catch 102, wherein one of the lock catch 102 and the locking assembly 101 is mounted on the vehicle body 30, and the other of the lock catch 102 and the locking assembly 101 is mounted on the vehicle door 20. Exemplarily, the lock catch 102 is mounted on the vehicle body 30, and the locking assembly 101 is mounted on the vehicle door 20.
