Description

Technical Field

[0001] The utility model relates to the field of vehicle seats, in particular to a mechanical shock-absorbing vehicle seat. Background Art

[0002] The shock-absorbing seat inflates or deflates the airbag through an air pump to achieve an upward supporting force on the seat surface by the pressure inside the airbag, so as to balance the bearing capacity on the seat surface and meet the usage requirements of different people. When the passenger adjusts the pressure inside the airbag according to their own weight and preference, during driving, due to the change of road conditions, the pressure of the passenger on the upper surface of the seat will change accordingly.

[0003] The current shock-absorbing seats use airbag shock absorption, but airbag shock absorption requires a relatively large volume, resulting in limitations in the use of the seats. Therefore, it is necessary to propose a mechanical shock-absorbing vehicle seat with a small occupied volume. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a mechanical shock-absorbing vehicle seat, which adopts a mechanical shock-absorbing structure and reduces the overall volume of the vehicle seat by adjusting the shape of the components.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a mechanical shock-absorbing vehicle seat, including a scissor mechanism connected between a bottom frame and a seat frame, a compression spring is vertically connected between the bottom frame and the seat frame, an adjustable damper is connected between the scissor mechanism and the bottom frame, a control switch for controlling the adjustable damper is installed on the seat frame, a horizontally arranged connecting plate is installed on the seat frame, and the upper end of the compression spring is connected to the connecting plate.

[0006] In a preferred embodiment of the utility model, both ends of the connecting plate are on the seat frame, and the width of both ends of the connecting plate is smaller than the width of the middle part of the connecting plate.

[0007] In a preferred embodiment of the utility model, the connecting plate is provided with waist-shaped weight-reducing holes and circular weight-reducing holes, and the waist-shaped weight-reducing holes are symmetrically arranged on both sides of the circular weight-reducing hole.

[0008] In a preferred embodiment of the utility model, a reinforcing plate is further installed on the seat frame, and the reinforcing plate is located at the rear end of the connecting plate.

[0009] In a preferred embodiment of the utility model, the scissor mechanism is an X-shaped scissor mechanism composed of two plate bodies, and the thickness of the plate body is 3 mm.

[0010] The beneficial effects of the present utility model are as follows: The mechanical shock-absorbing vehicle seat of the present utility model uses a compression spring as a shock-absorbing component, in cooperation with a damper whose softness and hardness can be adjusted, to achieve the shock absorption of the seat. At the same time, the compression spring is small in volume, which can reduce the height of the mechanical shock-absorbing vehicle seat.

[0011] For the mechanical shock-absorbing vehicle seat of the present utility model, by adjusting the shapes of the connecting plate and the scissor mechanism, the weight and volume of the components can be effectively reduced, and the occupied space of the mechanical shock-absorbing vehicle seat can be further reduced.

The structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those who are familiar with this technology to understand and read, and are not used to limit the limited conditions for the implementation of the present utility model. Therefore, they do not have a substantial technical meaning. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not used to limit the scope of implementation. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0017] Please refer to Figure 1 and Figure 2, a mechanical shock-absorbing car seat, including a scissor mechanism 3 connected between a bottom frame 1 and a seat frame 2. The structures of the scissor mechanism 3 and the bottom frame 1 are the same as those of the patent ZL202111607144.X previously applied by the applicant, and will not be elaborated here.

[0018] An adjustable damper 4 is connected between the scissor mechanism 3 and the bottom frame 1, and a control switch 5 for controlling the adjustable damper 4 is installed on the seat frame 2. The adjustable damper 4 has the function of adjustable soft and hard damping. The control switch 5 has a hard damping gear and a soft damping gear, and the soft and hard adjustment of the adjustable damper 4 is realized through the control switch 5. The adjustable damper 4 and the control switch 5 belong to the prior art and will not be elaborated here.

[0019] A compression spring 6 is connected vertically between the bottom frame 1 and the seat frame 2. A horizontally arranged connecting plate 7 is installed on the seat frame 2, and the upper end of the compression spring 6 is connected to the connecting plate 7. Taking the compression spring 6 as a mechanical shock-absorbing component, compared with the airbag, the compression spring 6 has a smaller volume, which can reduce the height of the car seat in the vertical direction and is beneficial to reducing the volume of the car seat.

[0020] Both ends of the connecting plate 7 are on the seat frame 2, and the widths of both ends of the connecting plate 7 are smaller than the width of the middle part of the connecting plate. Waist-shaped weight-reducing holes and circular weight-reducing holes are provided on the connecting plate 7, and the waist-shaped weight-reducing holes are symmetrically arranged on both sides of the circular weight-reducing hole. The middle part of the seat frame 2 is made hollow. The connecting plate 7 serves as a component for connecting the compression spring 6 and at the same time as a connecting component on both sides of the seat frame 2, reducing the workpiece material and reducing the weight of the seat.

[0021] A reinforcing plate 8 is also installed on the seat frame 2, and the reinforcing plate 8 is located at the rear end of the connecting plate 7. The reinforcing plate 8 also serves as a connecting part to ensure the connection reliability of the seat frame 2.

[0022] The scissor mechanism 3 is an X-shaped scissor mechanism composed of two plate bodies, and the thickness of the plate body is 3 mm. Optimize the size of the scissor mechanism to further reduce the volume of the car seat.

[0023] Different from the prior art, the mechanical shock-absorbing car seat of the present utility model adopts a mechanical shock-absorbing structure and reduces the overall volume of the car seat by adjusting the shape of the components.

[0024] The above schematically describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
