Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and particularly relates to a force relief device for an automobile seat during a collision. Background Art

[0002] An automobile seat slide rail comprises an upper slide rail and a lower slide rail, and the upper slide rail can slide on the lower slide rail by means of manual or electric drive. Currently, in an electric slide rail, the upper slide rail and the lower slide rail are usually driven by a transmission and a lead screw. The lead screw is fixedly installed in the lower slide rail, the transmission is in transmission connection with the lead screw, and at the same time, the transmission is fixedly connected with the upper slide rail. The motor drives the transmission to move along the lead screw, thereby driving the upper slide rail to move. However, currently, the seat lacks an X-direction inertia force absorption device, resulting in the X-direction collapse of the steering wheel during a vehicle collision, which is likely to cause the X-direction extrusion of the vehicle occupants and the occupants are prone to injury. Summary of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a force relief device for an automobile seat during a collision. When a collision occurs, the lead screw connection bracket breaks, which can effectively release the inertia force during the collision and play a role in protecting the safety of vehicle occupants.

[0004] The force relief device for an automobile seat during a collision provided by the utility model adopts the following technical solutions:

[0005] A force relief device for an automobile seat during a collision includes a seat frame body and a slide rail assembly. The slide rail assembly includes a lower slide rail arranged on the front floor, a driving lead screw arranged in the lower slide rail, and an upper slide rail arranged on the driving lead screw. The seat frame body is arranged on the upper slide rail. A connection bracket for installing the driving lead screw is arranged in the lower slide rail, and fracture notches are arranged on both sides of the connection bracket.

[0006] Further, the driving lead screw passes through the connection bracket, and the fracture notches are located below the driving lead screw.

[0007] Further, a shock absorber is arranged on the front floor. The shock absorber is arranged at both ends of the lower slide rail and is on the same straight line as the lower slide rail, and the end of the shock absorber contacts the end of the lower slide rail.

[0008] Further, an anti-disengagement plate for preventing the seat from disengaging is arranged at the front end of the lower slide rail.

[0009] Further, a fixing bracket for fixing on the front floor is arranged at the bottom of the lower slide rail.

[0010] Further, an installation table for installing the lower slide rail is arranged on the front floor.

[0011] Further, positioning holes are arranged on the installation table.

[0012] Furthermore, positioning points for fixing shock absorbers are provided on the front floor.

[0013] In summary, the present utility model includes at least one of the following beneficial effects: The slide rail assembly is divided into upper and lower slide rails, and the upper and lower slide rails are connected by a screw rod connecting bracket. Fracture notches are provided on both sides of the connecting bracket of the screw rod. The connecting bracket is designed to be wide at both ends and narrow in the middle. When a collision occurs, the screw rod connecting bracket breaks, which can effectively release the inertial force during the collision and play a role in protecting the safety of the vehicle occupants.

[0019] The following specific examples illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0020] The following is a further detailed description of the present utility model in conjunction with the attached Figures 1-3 drawings.

[0021] An embodiment of the present utility model discloses a force-releasing device for an automobile seat during a collision. Refer to Figures 1-3, the force - releasing device of the vehicle seat during a collision includes a seat - frame body 1 and a slide - rail assembly. The slide - rail assembly includes a lower slide - rail 2 disposed on the front floor 6, a driving lead - screw 3 disposed within the lower slide - rail 2, and an upper slide - rail 4 disposed on the driving lead - screw 3. The seat - frame body 1 is disposed on the upper slide - rail 5. A connecting bracket 21 for installing the driving lead - screw 3 is disposed within the lower slide - rail 2. Fracture notches are provided on both sides of the connecting bracket 21. The slide - rail assembly is divided into an upper and a lower slide - rail, and the upper and lower slide - rails are connected through the connecting bracket 21 of the lead - screw. The connecting bracket 21 of the lead - screw is designed to be wide at both ends and narrow in the middle. When a collision occurs, the connecting bracket 21 of the lead - screw breaks, which can effectively release the inertial force during the collision and play a role in protecting the safety of the vehicle occupants.

[0022] In this embodiment, the driving lead - screw 3 passes through the connecting bracket 21, and the fracture notch is located below the driving lead - screw 3. When a collision occurs, the driving lead - screw 3 acts on the connecting bracket 21 under the action of force, making it easier for the connecting bracket 21 to break at the position of the fracture notch.

[0023] In this embodiment, a shock absorber 5 is further disposed on the front floor 6. The shock absorber 5 can be a hydraulic shock absorber or a spring shock absorber. The shock absorber 5 is disposed at both ends of the lower slide - rail 2 and is in the same straight line as the lower slide - rail 2. Only the shock absorber 5 at the front end of the lower slide - rail 2 is shown in the attached drawings of this embodiment. The arrangement of the shock absorber 5 at the rear end of the lower slide - rail 2 is the same as that at the front end, so no redundant display is made here. The end of the shock absorber 5 contacts the end of the lower slide - rail 2. When the connecting bracket 21 breaks and the seat slides forward and backward, the shock absorbers 5 at the front and rear can play a role in buffering the inertial force during the collision and reducing the injury to the vehicle occupants.

[0024] In this embodiment, an anti - detachment plate 22 for preventing the seat from detaching is disposed at the front end of the lower slide - rail 2, which can prevent the seat from detaching from the lower slide - rail 21 after the connecting bracket 21 breaks and can play an anti - detachment role for the seat.

[0025] In this embodiment, a fixing bracket 23 for fixing to the front floor 6 is disposed at the bottom of the lower slide - rail 2. The fixing bracket 23 is fixed to the front floor 6 through a positioning pin.

[0026] In this embodiment, an installation platform 61 for installing the lower slide - rail 2 is disposed on the front floor 6, and positioning holes 62 are provided on the installation platform 61. When installing the seat, the positioning pin on the fixing bracket 23 is fixed in the positioning holes 62.

[0027] In this embodiment, positioning points 63 for fixing the shock absorber 5 are disposed on the front floor 6, which facilitates installing both ends of the shock absorber 5 on the front floor 6 through the positioning points 63.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
