[0001] The present application relates to the field of door locks, and in particular to a handle base, a door lock and a vehicle. Background Art

[0002] After the door lock is unlocked, the outer handle returns quickly and has a large impulse, resulting in a loud collision sound between the outer handle and the door sheet metal, which leads to a poor customer experience. In the related art, a damper arranged on the base body is connected to a gear of a control rod arranged on the base body, and the control rod abuts against the outer handle to slow down the return speed of the outer handle, thereby reducing the collision sound between the outer handle and the door sheet metal.

[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0038] The flat hidden exterior handle is embedded in the vehicle body or door when not in use. When the user wants to unlock, the exterior handle is first pulled / popped out of the vehicle body or door under the action of external force, and then unlocked. Figure 1 , Figure 3 and Figure 4 The door lock comprises a control rod unlocking block 4, a handle base 3, an axle pin 6 and an outer handle, wherein the control rod unlocking block 4 is rotatably connected to the handle base 3 via a rotating shaft 5. A first arc-shaped slideway 2 is provided on the handle base 3, and the control rod unlocking block 4 is provided with a second arc-shaped slideway 41. Along the depth direction of the first arc-shaped slideway 2, the second arc-shaped slideway 41 is stacked with the first arc-shaped slideway 2, and the length of the second arc-shaped slideway 41 is less than the length of the first arc-shaped slideway 2. One end of the second arc-shaped slideway 41 corresponds to one end of the first arc-shaped slideway 2, and the other end of the second arc-shaped slideway 41 corresponds to the middle pre-unlocking position of the first arc-shaped slideway 2.

[0039] The outer handle is connected to the shaft pin 6 through a connecting piece. The outer handle drives the shaft pin 6 to move along the first arc-shaped slide 2 on the handle base 3. When the outer handle is pulled / popped out of the vehicle body or door, it corresponds to: the shaft pin 6 moves from the initial position of the first arc-shaped slide 2 to the middle pre-unlocking position. When the shaft pin 6 reaches the middle pre-unlocking position, its outer peripheral surface abuts against the other end of the second arc-shaped slide 41. The outer handle continues to drive the shaft pin 6 to move along the first arc-shaped slide 2 through the connecting piece. The shaft pin 6 drives the control rod unlocking block 4 to rotate and unlock the control rod unlocking block 4. When the control rod unlocking block 4 rotates to the preset target position, the shaft pin 6 moves to the unlocking position of the second arc-shaped slide 41. Usually, the unlocking position is the other end of the second arc-shaped slide 41, and the initial position is one end of the second arc-shaped slide 41. After the door lock is unlocked, the control rod unlocking block 4 quickly rotates to the original position under the action of the return elastic member. In this process, the control rod unlocking block 4 drives the shaft pin 6 to quickly return from the unlocking position to the middle pre-unlocking position. The inventors found that when the control lever unlocking block 4 drives the axle pin 6 to return to the middle pre-unlocking position, the axle pin 6 will hit the outer wall 21 of the first arc-shaped slideway 2 under the action of centrifugal force, generating a high decibel noise, affecting the user's car experience.

[0040] In view of this, the embodiment of the present application provides a handle base 3, and a slideway buffer 1 is arranged on the outer side wall 21 of the first arc-shaped slideway 2 to prevent the shaft pin 6 from directly hitting the outer side wall 21 of the first arc-shaped slideway 2 when returning to the middle pre-unlocking position, thereby reducing the noise of the door lock. Figure 1 and Figure 2 As shown, the handle base 3 provided in the embodiment of the present application includes a base body, a first arc-shaped slide 2 is formed on the base body, and a slide buffer 1 is provided on the radial outer side wall 21 of the first arc-shaped slide 2. The first arc-shaped slide 2 has a starting position, an intermediate pre-unlocking position and an unlocking position along the length direction, and the slide buffer 1 is located at the intermediate pre-unlocking position.

[0041] Usually, the initial position is one end of the second arc-shaped slide 41, and the unlocking position is the other end of the second arc-shaped slide 41. The middle pre-unlocking position is located between the two ends and is spaced apart from both ends. For example, the middle pre-unlocking position is located in the middle of the first arc-shaped slide 2, or the middle pre-unlocking position can also be close to any end of the first arc-shaped slide 2.

[0042] The embodiment of the present application arranges a slide buffer 1 on the outer side wall 21 of the first arc-shaped channel of the handle base 3 and arranges the slide buffer 1 at the middle pre-unlocking position of the first arc-shaped channel to avoid the axle pin 6 directly hitting the outer side wall 21 of the first arc-shaped slide when returning to the middle pre-unlocking position and generating noise, thereby reducing the noise when the door lock is unlocked.

[0043] The slideway buffer 1 can be an elastic body that is attached to the outer side wall 21 of the first curved slideway 2. The elastic body is a rubber block or other structure with elastic deformation ability. Considering the service life of the slideway buffer 1 and the cost and difficulty of replacing or repairing the slideway buffer 1 on the handle base 3 of the door lock, in some embodiments of the present application, the slideway buffer 1 is plugged into the outer side wall 21 of the first curved slideway 2.

[0044] When implementing it specifically, Figure 1 and Figure 2As shown, the outer wall 21 of the first arc-shaped slide 2 is provided with a plug hole 22, the handle base 3 has a cavity connected to the plug hole 22, the slide buffer 1 includes a connecting portion 11 and a buffer portion 12, at least part of the connecting portion 11 is located in the cavity and abuts against the side of the cavity close to the first arc-shaped slide 2, the buffer portion 12 is plugged into the plug hole 22 and connected to the connecting portion 11, and part of the buffer portion 12 is located in the first arc-shaped slide 2. The connecting portion 11 is snapped into the cavity of the handle base 3, and the buffer portion 12 protrudes from the outer wall 21 of the first arc-shaped slide 2 through the plug hole 22. When the shaft pin 6 hits, it is blocked by the buffer portion 12 and will not hit the outer wall 21 of the first arc-shaped slide 2. The connecting portion 11 of the slide buffer block serves as a connecting support for the buffer portion 12. The slide buffer 1 is firmly connected to the first arc-shaped slide 2 and is not easy to fall off.

[0045] In some embodiments, the hardness of the connecting portion 11 is greater than the hardness of the buffering portion 12. For example, the connecting portion 11 may be a hard plastic part made by injection molding, and the hardness of the connecting portion 11 is 35SHD-45SHD. For example, the hardness of the connecting portion 11 may be 35SHD, 38SHD, 40SHD, and 45SHD. The buffering portion 12 is a soft plastic part, and the hardness of the buffering portion 12 is 50-60SHA. For example, the hardness of the buffering portion 12 may be 50SHA, 54SHA, 58SHA, and 60SHA. The connecting portion 11 supports the buffering portion 12, and the buffering portion 12 has a large elastic deformation capacity. The buffering portion 12 can better absorb the energy of the shaft pin 6 when it is hit, and it will hardly produce any sound when it is hit by the shaft pin 6.

[0046] In some embodiments, Figure 2 As shown, a groove 111 is provided on one side of the connecting portion 11 facing the insertion hole 22, and the buffer portion 12 has a connecting end and a free end 121 opposite to each other along the radial direction of the first arc-shaped slideway 2, and the free end 121 is used to receive the collision of the shaft pin 6, and the connecting end is located in the groove 111, and along the radial direction of the first arc-shaped slideway 2, the projection of the insertion hole 22 on the bottom wall of the groove 111 is located within the projection of the connecting end on the bottom wall of the groove 111. The connecting end is interference-fitted in the groove 111 to achieve connection with the connecting portion 11, and both sides of the connecting end are clamped with the first arc-shaped slideway 2 through the groove 111, so as to prevent the buffer portion 12 from falling off due to the thrust along the tangential direction of the first arc-shaped slideway 2 when its free end 121 is hit by the shaft pin 6.

[0047] Furthermore, a portion of the bottom wall of the groove 111 protrudes radially along the first arc-shaped slide 2 to form a convex portion 112, and the convex portion 112 is inserted into the connecting end to better connect the connecting portion 11 with the buffer portion 12, and the convex portion 112 can provide support for the buffer portion 12 to increase the impact resistance of the buffer portion 12.

[0048] If the convex portion 112 is too long, it will affect the free end 121 of the buffer portion 12 from absorbing the energy when the shaft pin 6 hits it. If the convex portion 112 is too short, the buffer portion 12 will be easily dislodged due to the thrust along the tangential direction of the first arc-shaped slideway 2 when the free end 121 of the buffer portion 12 is hit by the shaft pin 6. Therefore, the convex portion 112 extends into the insertion hole 22 and the end of the convex portion 112 is spaced from both ends of the insertion hole 22 along its length direction. For example, Figure 2 As shown, the end of the protrusion 112 is located in the middle of the insertion hole 22 .

[0049] In some embodiments, Figure 2 As shown, the first positioning portion 113 is provided on the side of the connecting portion 11 facing away from the first arc-shaped slideway 2, and a second positioning portion 32 is provided on the side wall of the cavity of the base body to match the first positioning portion 113. This prevents the connecting portion 11 from being able to move in the cavity of the base body due to machining errors, thereby affecting the collision of the slideway buffer 1 with the shaft pin 6. One of the first positioning portion 113 and the second positioning portion 32 can be a positioning groove, and the other can be a positioning boss.

[0050] Another embodiment of the present application provides a door lock, such as Figures 1 to 4 The door lock includes the handle base 3, the control rod unlocking block 4, the shaft pin 6 and the outer handle.

[0051] The control lever unlocking block 4 is rotatably connected to the handle base 3 through a rotating shaft 5, and the control lever unlocking block 4 is provided with a second arc slide 41. Along the depth direction of the first arc slide 2, the second arc slide 41 and the first arc slide 2 are stacked, and the length of the second arc slide 41 is less than the length of the first arc slide 2; wherein, one end of the second arc slide 41 corresponds to the initial position of the first arc slide 2, and the other end of the second arc slide 41 corresponds to the middle pre-unlocking position of the first arc slide 2.

[0052] The shaft pin 6 is along the depth direction of the first arc-shaped slideway 2, and the shaft pin 6 is sequentially inserted into the second arc-shaped slideway 41 and the first arc-shaped slideway 2. The outer handle is connected to the shaft pin 6 through a connecting piece. The outer handle drives the shaft pin 6 to move along the first arc-shaped slideway 2 on the handle base 3.

[0053] When the outside handle is pulled / popped out of the vehicle body or door, it corresponds to: the shaft pin 6 moves from the initial position of the first arc-shaped slide 2 to the middle pre-unlocking position. When the shaft pin 6 reaches the middle pre-unlocking position, its outer peripheral surface abuts against the other end of the second arc-shaped slide 41, and the outside handle continues to drive the shaft pin 6 to move along the first arc-shaped slide 2 through the connecting member, and the shaft pin 6 drives the control rod unlocking block 4 to rotate and unlock the control rod unlocking block 4. When the control rod unlocking block 4 rotates to the preset target position, the shaft pin 6 moves to the unlocking position of the second arc-shaped slide 41. Usually, the unlocking position is the other end of the second arc-shaped slide 41, and the initial position is one end of the second arc-shaped slide 41. After the door lock is unlocked, the control rod unlocking block 4 quickly rotates to the original position under the action of the return elastic member. During this process, the control rod unlocking block 4 drives the shaft pin 6 to quickly return from the unlocking position to the pre-unlocking position. When the control rod unlocking block 4 drives the shaft pin 6 to return to the pre-unlocking position, the shaft pin 6 will hit the slideway buffer 1, that is, the shaft pin 6 will be blocked by the slideway buffer 1 and will not hit the outer side wall 21 of the first arc-shaped slideway 2 when hitting.

[0054] In some embodiments, Figure 4 and Figure 5 As shown, the handle base 3 is provided with a limit portion 31, the control lever unlocking block 4 has a return stop end 42, the limit portion 31 is used to abut against the return stop end 42, the return stop end 42 is provided with a limit buffer block 43, and the limit buffer block 43 has a plurality of convex points 431 on one side close to the limit portion 31. Of course, the limit buffer block 43 can also be provided on the limit portion 31 and located between the return stop end 42 and the limit portion 31.

[0055] When the control rod unlocking block 4 drives the axle pin 6 to return to the pre-unlocking position, the limit portion 31 abuts against the return stop end 42 of the control rod unlocking block 4 to restrict its continued rotation. Noise will also be generated when the limit portion 31 contacts the return stop end 42. A limit buffer block 43 is provided at the return stop end 42 to reduce this noise, thereby further reducing the noise when the door lock is unlocked.

[0056] Yet another embodiment of the present application provides a vehicle, the vehicle comprising the above-mentioned door lock.
