Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to an automobile safety handle and an automobile thereof. Background Art
[0002] An automobile safety handle is a commonly used component in an automobile, usually installed on the automobile ceiling. When a passenger enters or leaves the vehicle, the safety handle can be used to stabilize the body; during the driving process of the vehicle, the safety handle can provide stable support for the passengers to help them maintain a good sitting posture. This is very important for the comfort and safety of passengers during riding.
[0003] With the increasing attention of consumers to automobile noise, many automobile manufacturers take noise reduction as the focus of their product design. Since the safety handle needs to fit on the automobile ceiling when not in use to reduce the occupation of the interior space of the vehicle, a reset member is usually provided to make it return from the unfolded state during use to the state when not in use. During the recovery process, it is easy to collide with the automobile ceiling and then generate noise.
[0004] Therefore, a damper is added to the existing automobile safety handle. During the rebound process of the automobile safety handle, the damper makes the ceiling handle return slowly to solve the collision problem caused by the safety handle during the return process. However, its cost is relatively high, the structure is relatively complex, and in the case of long-term strong pulling, the damping safety handle will have the problems of incomplete rebound of the handle and damping force decay. Summary of the Utility Model
[0005] Aiming at the above technical problems, the utility model provides an automobile safety handle.
[0006] An automobile safety handle includes: a fixed base for fixedly connecting with an automobile ceiling; a handle rotatably connected with the fixed base; a reset member disposed between the fixed base and the handle and connected with the fixed base and the handle, and capable of driving the handle to rotate towards the fixed base; an elastic member disposed on a side of the handle close to the fixed base; wherein, an installation groove is formed on a side of the handle facing the fixed base, the elastic member is embedded in the installation groove, and a side surface of the elastic member close to the fixed base is configured as an arc surface.
[0007] With such a setting, when a passenger needs to use the handle, the handle can be directly pulled. The handle rotates relative to the fixed base to a position convenient for the passenger to use. When the passenger releases the handle after use, the reset member can drive the handle to return to the initial position (fitting against the vehicle ceiling). The elastic member is arranged on the side of the handle close to the fixed base. Therefore, as the handle moves towards the fixed base, the elastic member can first abut against the vehicle ceiling and reduce the noise caused by the collision through its elastic damping effect, thereby improving the interior quality of the vehicle. And the side of the elastic member close to the fixed base is set as an arc surface. Therefore, the installation of the elastic member is more stable. After being limited by multiple groove walls of the installation groove, it can be prevented from coming out. And because the arc surface is constructed on the elastic member, the arc surface can further reduce the noise generated when the elastic member impacts the vehicle ceiling, and can also reduce the stress load brought by the collision, increase the contact area, and reduce the impact on the elastic member and the vehicle ceiling caused by the collision.
[0008] In one embodiment, the elastic member includes a connecting section and an abutting section. The connecting section is embedded in the installation groove, and the abutting section is connected to the connecting section and extends towards the fixed base.

Along the first direction away from the connecting section, the thickness of the abutting section gradually decreases in the second direction close to or away from the fixed base, and the first direction and the second direction are arranged at an angle.
[0010] In one embodiment, an abutting block protrudes from the elastic member, and the abutting block abuts against the notch of the installation groove.
[0011] In one embodiment, a receiving groove is formed in the handle, an installation block is arranged in the receiving groove, the installation block is connected to the groove wall of the receiving groove, and the installation groove is formed in the installation block.
[0012] In one embodiment, a reinforcing rib protrudes from one side of the installation block towards the fixed base, and a part of the reinforcing rib is connected to the bottom of the receiving groove and extends towards the fixed base.
[0013] In one embodiment, the handle includes a main body portion and a connecting portion. The connecting portion is connected to both ends of the main body portion, and both ends of the two connecting portions are respectively connected to the vehicle ceiling through the two fixed bases.
[0014] In one embodiment, the elastic members are arranged on both of the two connecting portions, the bottom of the installation groove is set as an arc structure, and the part of the elastic member extending into the installation groove is also set as an arc structure and is adapted to the installation groove.
[0015] In one of the embodiments, a first through hole is formed in the fixed base, a second through hole is formed in the handle, the first through hole and the second through hole are coaxially arranged and a rotating shaft is passed through them, and the reset member is arranged as a torsion spring.
[0016] The present utility model provides an automobile, including the automobile safety handle as described above.
[0017] Compared with the prior art, for the automobile safety handle provided by the present utility model, by arranging an elastic member on one side of the handle close to the fixed base, as the handle moves towards the fixed base, the elastic member can first abut against the vehicle roof, and reduce the noise caused by the collision through its elastic damping effect, thereby improving the interior quality of the vehicle. And because the elastic member is constructed with an arc surface, the arc surface can further reduce the noise generated when the elastic member impacts the vehicle roof, and can also reduce the stress load brought by the collision, increase the contact area, and reduce the impact on the elastic member and the vehicle roof caused by the collision.

[0028] The present utility model provides an automotive safety handle 100, and an elastic member 30 is arranged on the handle 20 to reduce the noise generated by the collision between the handle 20 and the automotive ceiling through the shock absorption effect of the elastic member 30.
[0029] Please refer to Figures 1 - 3, the vehicle safety handle 100 includes a fixed base 10, a handle 20, a reset member, and an elastic member 30. The fixed base 10 is used for fixedly connecting with the vehicle ceiling. The handle 20 is rotatably connected to the fixed base 10. The reset member is disposed between the fixed base 10 and the handle 20, and is connected to the fixed base 10 and the handle 20, and can drive the handle 20 to rotate towards the fixed base 10. When a passenger needs to use the handle 20, the handle 20 can be directly pulled, and the handle 20 rotates relative to the fixed base 10 to a position convenient for the passenger to use. When the passenger finishes using and releases the handle 20, the reset member can drive the handle 20 to return to the initial position (fitting against the vehicle ceiling). The elastic member 30 is disposed on the side of the handle 20 close to the fixed base 10. Therefore, as the handle 20 moves towards the fixed base 10, the elastic member 30 can first abut against the vehicle ceiling, and reduce the noise caused by the collision through its elastic shock absorption effect, thereby improving the interior quality of the vehicle. And an installation groove 21 is formed on the side of the handle 20 facing the fixed base 10. The elastic member 30 is embedded in the installation groove 21, and the side surface of the elastic member 30 close to the fixed base 10 is set as an arc surface 31. Therefore, the installation of the elastic member 30 is more stable. After being limited by the multiple groove wall surfaces of the installation groove 21, it can be prevented from coming out. And because the arc surface 31 is formed on the elastic member 30, the arc surface 31 can further reduce the noise generated when the elastic member 30 impacts the vehicle ceiling, and can also reduce the stress load brought by the collision, increase the contact area, and reduce the impact brought by the collision to the elastic member 30 and the vehicle ceiling.
[0030] The elastic member 30 includes a connecting section 33 and an abutting section 34. The connecting section 33 is embedded in the installation groove 21, and the abutting section 34 is connected to the connecting section 33 and extends towards the fixed base 10. In this way, the connecting section 33 and the abutting section 34 independently play their roles, avoiding mutual interference and influence.
[0031] Further, the arc surface 31 is formed on the abutting section 34. Along a first direction away from the connecting section 33, the thickness of the abutting section 34 gradually decreases in a second direction close to or away from the fixed base 10, and the first direction and the second direction are arranged at an angle. It should be explained that the thickness of the abutting section 34 refers to the distance between the side surface of the abutting section 34 close to the fixed base 10 and the side surface away from the fixed base 10 in the rotation direction of the handle 20. The reduction of the thickness of the abutting section 34 can, on the one hand, save materials and reduce costs, and can make it more easily deformable, thereby further reducing the noise generated by its collision with the vehicle ceiling and reducing the damage caused by the collision.
[0032] In other embodiments, the thickness of the abutting section 34 can also remain unchanged, that is, set as a rectangular structure, or the thickness can first increase and then decrease, that is, wide in the middle and narrow at the top, and can also form an arc section, and can also improve the structural strength of the abutting section 34.
[0033] Preferably, the bottom of the installation groove 21 is also set to an arc structure, and the part of the connecting section 33 extending into it is also adapted to the installation groove 21 and is also set to an arc structure. The arc-shaped abutting surface can make the assembly of the two more convenient, the force transmission between them more smooth, and the mutually adapted and fitted structure makes the two connected tightly, preventing the elastic member 30 from coming out.
[0034] Furthermore, the elastic member 30 is provided with a protruding abutting block 32, and the abutting block 32 abuts against the notch of the installation groove 21. The abutting block 32 can act on the elastic member 30 along its length direction (that is, the grooving direction of the installation groove 21, or the orientation of the notch of the installation groove 21). And with the abutting and extrusion of the abutting section 34 against the vehicle ceiling, the abutting block 32 can distribute the stress on the abutting section 34, so that more energy can be absorbed during the rebounding process of the handle 20, achieving a better damping effect.
[0035] Preferably, in this embodiment, the abutting block 32 is formed on the abutting section 34 and is located outside the installation groove 21 for the convenience of assembling the elastic member 30.
[0036] The handle 20 is provided with a receiving groove 22, and an installation block 23 is arranged in the receiving groove 22. The installation block 23 is connected to the groove wall of the receiving groove 22, and the installation groove 21 is opened in the installation block 23. The installation block 23 is used for installing the elastic member 30, so that the elastic member 30 does not need to be welded or glued to the handle 20, improving the limiting effect on the elastic member 30 and ensuring that it will not fall off the handle 20. The receiving groove 22 provides a space for installing the installation block 23, preventing the handle 20 from colliding and interfering with the fixed base 10 or other structures during the reset process, and also enabling the lightweight of the handle 20.
[0037] Furthermore, a reinforcing rib 231 protrudes from the side of the installation block 23 facing the fixed base 10, and a part of the reinforcing rib 231 is connected to the bottom of the receiving groove 22 and extends in the direction of the fixed base 10. In this way, the reinforcing rib 231 can improve the structural strength of the installation block 23 and also improve the connection strength between the installation block 23 and the bottom of the receiving groove 22.
[0038] Specifically, in this embodiment, two reinforcing ribs 231 are provided and are respectively connected to both edges of the width direction of the side of the installation block 23 facing the fixed base 10 to provide higher structural strength.
[0039] The handle 20 includes a main body portion 24 and a connecting portion 25. The connecting portion 25 is connected to both ends of the main body portion 24, and both ends of the two connecting portions 25 are respectively connected to the vehicle ceiling through the two fixed bases 10. Elastic members 30 are arranged on both connecting portions 25. In this way, the rotation of the handle 20 is more stable, and the connection strength with the fixed base 10 is also higher.
[0040] Understandably, in this embodiment, the above-mentioned accommodation grooves 22 are formed in both of the two connecting portions 25. An installation block 23 is arranged in each accommodation groove 22, and an installation groove 21 is formed in the installation block 23 to fix the elastic member 30.
[0041] A first through hole is formed in the fixed base, and a second through hole is formed in the handle 20. The first through hole and the second through hole are coaxially arranged and a rotating shaft 40 is passed through them, and the reset member is arranged as a torsion spring. In this way, the torsion spring structure has a low cost, a stable and simple structure, and a good reset effect.
[0042] The present invention also provides an automobile, including the vehicle safety handle 100 as described above.
[0043] Compared with the prior art, for the vehicle safety handle 100 provided by the present invention, by arranging the elastic member 30 on the side of the handle 20 close to the fixed base 10, as the handle 20 moves towards the fixed base 10, the elastic member 30 can first abut against the vehicle ceiling, and reduce the noise caused by the collision through its elastic shock absorption effect, thereby improving the interior quality of the vehicle. And because the elastic member 30 is constructed with an arc surface 31, the arc surface 31 can further reduce the noise generated when the elastic member 30 impacts the vehicle ceiling, and can also reduce the stress load brought by the collision, increase the contact area, and reduce the impact on the elastic member 30 and the vehicle ceiling caused by the collision.
[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0045] The above-mentioned embodiments only express several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
