Description

Technical Field

[0001] The present invention relates to the structure of automotive parts, in particular to a safety handle and an automobile. Background Art

[0002] The existing traditional safety handle is provided with a plastic handle, two pin shafts are connected to both ends of the handle, and two springs form its main body. It is connected to the sheet metal of the automobile ceiling using bolts and rotates under force during use.

[0003] Components such as the legs, pin shafts, and springs at both ends of the existing safety handle are exposed on the surface of the automobile ceiling. The formed assembly has a large protrusion on the ceiling surface, which may touch the heads of passengers, affecting the safety of the automobile. Moreover, this protrusion also occupies the internal space of the automobile, affecting the comfort of the automobile. Summary of the Invention

[0004] The purpose of the present invention is to provide a safety handle to avoid touching the heads of passengers and improve the safety of the automobile.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions.

[0006] A safety handle includes a handle capable of bending and deforming and a housing. Both ends of the handle are provided with foldable handle legs, and two torsion springs for driving their folding are connected to the handle legs; a limiting structure is further included, and the limiting structure is used to limit the extreme position of the handle legs when they are unfolded; the limiting structure and the handle legs are both installed in the housing, and the housing can be embedded inside the ceiling trim.

[0007] The foldable handle legs include a rotating arm, a pin shaft, and a connecting arm. The connecting arm has a T-shaped structure. The rod portion of the connecting arm is connected to a handle head through shaft hole fit, and the handle head is fixedly connected to the end of the handle; the free end of the connecting arm is hinged to one end of the rotating arm, and the other end of the rotating arm is shaft hole fit on the pin shaft, and the pin shaft is provided on the housing.

[0008] The limiting structure includes a limiting member and a first limiting portion formed on the rotating arm; a second limiting portion is formed on the limiting member, and the rotation position of the rotating arm is restricted by the abutment of the first limiting portion and the second limiting portion, thereby forming a limit on the extreme position of the handle legs when they are unfolded.

[0009] The housing is further formed with an obliquely arranged waist-shaped limiting hole, and both ends of the second limiting portion can be slidably fitted in the limiting hole.

[0010] The edge of the limiting member fixed to the housing is provided with a connection hole, and a through hole communicating with the connection hole is provided on the corresponding wall of the housing. A C-shaped open snap ring is further formed on this edge. The housing is fixed to the sheet metal part of the vehicle ceiling by screws through the through hole on the corresponding wall and the connection hole on the limiting member.

[0011] In the present invention adopting the foregoing technical solution, by arranging foldable handle legs at both ends of the handle capable of bending and deforming, the handle legs can automatically fold under the drive of a torsion spring. Utilizing the material property that the handle can bend, the positions of both ends of the handle change to approach or move away from each other, thereby meeting the requirement of the change in the connection position between the foldable handle legs and the handle, and enabling the overall handle to form a comprehensive telescopic deformation structure along the longitudinal direction and the pulling direction of the handle. After the housing provides a longitudinal deformation space, it is convenient to hide the foldable handle legs in the ceiling trim, avoiding contact with the heads of passengers and enhancing the safety of the vehicle. Among them, the handle can be made of a flexible material to achieve the purpose of changing the distance between both ends of the handle by bending and deforming. When in use, pull the handle outwards. During the process of pulling out the handle, both ends of the handle move inwards, and the middle part of the handle body arches outwards within the elastic deformation range, forming an arc with a good grip feeling. The inwards-moving both ends of the handle pull the foldable handle legs to unfold and gradually pull outwards until the handle legs reach the limit position under the action of the limiting structure. The limiting structure can ensure that the part of the middle of the handle that can remain horizontal is greater than the width of the hand grip, avoiding pinching the hands at both ends of the handle, enhancing the use comfort, and enabling the handle to have sufficient load capacity to ensure the safety of the handle.

[0012] When pulling out the handle, the handle head makes the connecting arm move downwards and towards the middle of the handle through the T-shaped head of the connecting arm, gradually reducing the distance between both ends of the handle, and the handle bends until the rotating arm rotates to a set angle and is limited to its limit position by the limiting structure, and the handle is at the maximum pulled-out position. Among them, the connecting arm is arranged in a T-shaped structure, and the T-shaped head is used to form the transmission of the motion relationship, so that the connection between its rod part and the mating hole on the handle head can form a sliding fit connection or a tight fit connection in various connection forms, and it is possible to avoid setting fasteners such as screws for fixed connection.

[0013] Preferably, the housing includes a decorative cover plate and two installation parts embedded in the ceiling trim. The installation parts are integrally in a box structure, and two installation holes are formed on each installation part, and are in shaft hole fit with both ends of the pin shaft through the installation holes.

[0014] In this way, by arranging two installation parts on the housing and setting installation holes on the installation parts to cooperate with the pin shaft of the handle leg structure, the position of the pin shaft on the housing is restricted and a supporting force is provided for the pin shaft.

[0015] Preferably, the handle head is integrally Z-shaped, and the two ends of the Z-shaped handle head are respectively connected to the handle end and the connecting arm.

[0016] In this way, it is convenient to hide more parts inside the ceiling trim.

[0017] Preferably, the torsion spring is sleeved on the pin shaft, and the support arms at both ends of the torsion spring are respectively abutted against the connecting arm and the housing.

[0018] In this way, a torsion spring is arranged on the pin shaft. After the handle is pulled out and then released, the rotating arm rotates under the restoring force of the torsion spring, causing the handle leg to fold, and making the handle fit against the outer side of the decorative cover plate of the housing, improving the aesthetics inside the vehicle.

[0019] Preferably, the first limiting part forms the end where the rotating arm is connected to the pin shaft.

[0020] By the abutment of the two limiting parts, reliable limiting is ensured.

[0021] Preferably, the limiting member is integrally in the structure of a spring sheet bent in the middle. The limiting member is fixedly connected to the housing through one side of the spring sheet, and a limiting shaft is installed at the distal end of the other side of the spring sheet. The limiting shaft constitutes the second limiting part, and the first limiting part is in the shape of an arc-shaped hook.

[0022] By setting the limiting member into the structure of a spring sheet and bending the spring sheet into two sections with an obtuse angle in the middle, fitting one side of the obtuse angle against the bottom of the installation part, and the other side will tilt upward, thus forming a simple reed-type elastic member. When the handle is pulled out, the rotation angle of the rotating arm can be restricted by means of elastic deformation. When the handle is released, the elastic force is also used to promote the reset of the rotating arm, thus forming a reset effect in combination with the torsion spring. Among them, the first limiting part is set in the shape of an arc-shaped hook, which is convenient for its combination and separation with the limiting shaft.

[0023] By arranging a kidney-shaped limiting hole on the installation part to install the limiting shaft, the two limit positions of the limiting shaft are thus defined, and the limiting hole provides a supporting force for the limiting shaft to ensure the load capacity of the handle in the maximum pulled-out state. Among them, the housing is fixed to the sheet metal part of the vehicle ceiling through the through holes on the corresponding wall and the connecting holes on the limiting member by screws, and the limiting member forms a fixed connection with the housing through the corresponding side. The limiting member can be temporarily clamped and fixed on the housing through the C-shaped opening snap ring on it, facilitating the formation of an integral structure of the handle component and convenient for component installation.

[0024] Preferably, buckles are formed around the decorative cover plate, and are snap-connected to the handle installation holes of the ceiling trim through the buckles. A connecting hook is formed at one end of the installation part away from the handle, and is connected to the vehicle ceiling sheet metal inside the ceiling trim through the connecting hook.

[0025] The housing is snap - connected to the ceiling trim by setting snap - fasteners, which facilitates hiding the traces at the connection with a decorative cover plate and further enhances the aesthetics of the vehicle. The connection hook is conducive to quick positioning during installation and improves the installation efficiency.

[0026] To achieve the above - mentioned purpose, the present invention also provides a vehicle, including the above - mentioned safety handle.

[0027] The beneficial effects of the present invention are as follows: by arranging foldable handle legs at both ends of the handle that can be bent and deformed, the handle legs can automatically fold under the drive of torsion springs. Utilizing the material property that the handle can be bent, the positions of both ends of the handle change, approaching or moving away from each other, thus meeting the requirements of the changing connection positions between the foldable handle legs and the handle, and enabling the overall handle to form a comprehensive telescopic deformation structure along the longitudinal direction and the pulling direction of the handle. After providing a longitudinal deformation space through the housing, it is convenient to hide the foldable handle legs in the ceiling trim to avoid touching the heads of passengers and improve the safety of the vehicle. Among them, the handle can be made of flexible material to achieve the purpose of changing the distance between both ends of the handle through bending deformation. When in use, pulling the handle outwards, during the process of pulling out the handle, both ends of the handle move inwards, and the middle part of the handle body arches outwards within the elastic deformation range, forming an arc with a good grip feeling. The in - ward - moving both ends of the handle pull the foldable handle legs to unfold and gradually pull outwards until the handle legs reach the limit position under the action of the limiting structure. The limiting member can ensure that the part of the middle of the handle that can remain horizontal is greater than the width of the hand grip, avoiding pinching the hands at both ends of the handle, improving the comfort of use, and enabling the handle to have sufficient load - bearing capacity to ensure the safety of the handle.
