Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, in particular to an anti-smashing and anti-extrusion automobile seat. Background Art

[0002] With the continuous development of the automobile industry, people have higher and higher requirements for the comfort, safety and functionality of car seats.

[0003] The traditional car seat structure usually includes a base, a seat part (including a backrest and a seat seat) and a connecting piece. The backrest and the seat seat are usually adjusted by a manual or electric angle adjuster to meet the sitting posture requirements of different passengers. The seat seat is usually connected to the base through a slide rail to facilitate sliding forward and backward to adjust the seat position.

[0004] However, in the prior art, the design of car seats mainly focuses on comfort, support and aesthetics, while relatively less attention is paid to anti-smashing performance. However, in actual situations, vehicles may encounter various emergency situations during driving, such as collisions, sudden braking, etc. In these situations, the seats may be subjected to large smashing forces, thereby causing injuries to passengers.

[0005] At present, there are some car seats on the market that claim to have anti-smash functions, but most of these seats use methods such as increasing the thickness of the seat frame, using high-strength materials, or adding a buffer layer to improve the anti-smash ability. However, these methods often have the following shortcomings:

[0006] 1. Insufficient anti-smash performance: When the vehicle collides or is hit by external forces, the seat structure is prone to deformation or damage, causing injuries to passengers. Some existing anti-smash measures can only reduce the damage to a certain extent, but cannot protect people to the maximum extent, and cannot provide effective anti-smash protection for rear passengers.

[0007] 2. Increased weight: Increasing the thickness of the seat frame or using high-strength materials will increase the overall weight of the seat, which will in turn affect the vehicle's fuel economy and handling performance.

[0008] 3. Rising costs: The design and production costs of high-strength materials and complex structures are high, which leads to rising seat prices and is not conducive to market promotion.

[0009] 4. Decreased comfort: Although adding a cushioning layer can improve the anti-smash ability, it may affect the support and comfort of the seat, especially when riding for a long time.

[0010] Therefore, a smash-proof and squeeze-proof automobile seat is proposed to solve the current shortcomings. Summary of the invention

[0011] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide an anti-smash and anti-extrusion car seat.

[0012] In order to solve the above technical problems, the technical solution provided by the present invention is an anti-smashing and anti-extrusion automobile seat: comprising a base, a seat part and an anti-smashing bracket;

[0013] The seat part includes a chair back and a seat, the chair back and the seat are rotatably connected via a rotating structure, a set of slide rails are parallelly arranged at the bottom of the seat, the seat is slidably arranged on the base, and a slideway matching the slide rails is arranged on the base;

[0014] The bottom of the anti-smash bracket is rotatably connected to the tail end of the base through a rotating structure 2, the upper part of the anti-smash bracket is rotatably connected to the upper part of the chair back through a rotating shaft, and the upper end of the anti-smash bracket is provided with a groove that cooperates with the headrest on the chair back.

[0015] An electric telescopic rod is rotatably provided at the lower part of the anti-smashing bracket, and the output end of the electric telescopic rod is rotatably connected to the chair back.

[0016] As an improvement, a mounting groove for mounting the slideway is provided on the base.

[0017] As an improvement, the slideway is in a C-shaped structure with its opening facing upward, and the slide rail matching the slideway is in a "J"-shaped structure with its opening facing downward.

[0018] As an improvement, the anti-smashing bracket includes an outer support frame, which has a trapezoidal frame structure as a whole. A "M"-shaped support frame is arranged inside the outer support frame. A reinforcing rod connected to the support frame and corresponding to the electric telescopic rod is arranged inside the outer support frame.

[0019] As an improvement, a reinforcement plate is provided at the connection of the support frame.

[0020] As an improvement, the rotating structure 1 and the rotating structure 2 are both angle adjusters.

[0021] The advantages of the present invention compared with the prior art are:

[0022] 1. Improve passenger safety: The combination design of the trapezoidal frame structure, the "M"-shaped support frame and the reinforcement plate ensures the high strength and high stability of the anti-smash bracket. The design of the anti-smash bracket effectively enhances the seat's ability to resist compression and deformation, and can effectively resist external smashing and impact, reducing the damage to personnel when the vehicle is smashed, squeezed or rolled over by a large vehicle.

[0023] 2. Improve passenger comfort: The combination of the electric recliner and the electric telescopic rod enables flexible adjustment of the seat angle and all-round angle adjustment of the seat to meet the personalized needs of different passengers.

[0024] 3. Compact structure and light weight: The seat has a compact structure design, which ensures strength while achieving the characteristics of lightness and compactness. It does not take up too much space in the car and does not affect riding comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the invention clearer, the technical solution in the embodiments of the invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the invention. Obviously, the described embodiments are part of the embodiments of the invention, not all of the embodiments. Generally, the components of the embodiments of the invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] In the description of the embodiments of the invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the invention product is usually placed when in use, it is only for the convenience of describing the invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of the embodiments of the invention, "a plurality of" means at least two.

[0038] In the description of the embodiments of the invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0039] As shown in the accompanying drawings, an anti-smash and anti-extrusion car seat includes a base 1, a seat portion 2 and an anti-smash bracket 3;

[0040] The seat portion 2 includes a backrest 21 and a seat 22. In the present embodiment, the backrest 21 and the seat 22 both adopt the existing technology. The backrest 21 and the seat 22 are rotatably connected via a rotating structure 23. The rotating structure 23 adopts an electric angle adjuster. The angle adjuster also adopts the existing technology. By operating the adjuster, the angle between the backrest 21 and the seat 22 can be adjusted.

[0041] A set of slide rails 24 are parallelly arranged at the bottom of the seat 22, and the seat 22 is slidably arranged on the base 1, and a slideway 4 cooperating with the slide rails 24 is arranged on the base 1;

[0042] Furthermore, the base 1 is provided with a mounting groove 8 for mounting the slide 4, and the slide 4 is fixedly installed in the mounting groove 8. Under the premise of ensuring that the slide rail 24 and the slide rail 4 cooperate with each other, a small distance is maintained between the seat 22 and the base 1, so as to avoid the slide rail 24 and the slide rail 4 being compressed and deformed due to the large distance between the seat 22 and the base 1 when the seat part 2 is hit.

[0043] Furthermore, the slideway 4 is in a C-shaped structure with an opening facing upward, and the slide rail 24 that cooperates with the slideway 4 is in a "J"-shaped structure with an opening facing downward. Through the cooperation of the C-shaped structure of the slideway 4 and the "J"-shaped structure of the slide rail 24, the sliding contact area between the slide rail 24 and the slideway 4 can be further increased, the cooperation stability of the two can be improved, and the structural strength of the cooperation can be further improved, thereby ensuring the operation stability between the two.

[0044] The bottom of the anti-smash bracket 3 is rotatably connected to the tail end of the base 1 through a rotating structure 2 5. The rotating structure 2 5 adopts an electric angle adjuster, and the angle adjuster also adopts the existing technology. The anti-smash bracket 3 and the base 1 are rotatably connected through the setting of the rotating structure 2 5. The upper part of the anti-smash bracket 3 is rotatably connected to the upper part of the chair back 21 through a rotating shaft, which can facilitate the angle adjustment of the seat part 2 to meet the sitting and holding angle requirements of different people for the seat part 2.

[0045] The anti-smashing bracket 3 includes an outer support frame 31, and the outer support frame 31 has a trapezoidal frame structure as a whole. The trapezoidal frame structure can effectively disperse forces from different directions, enhance the overall compression and deformation resistance, and provide uniform support when subjected to external smashing force to avoid local stress concentration.

[0046] A "M"-shaped support frame 32 is provided in the outer support frame 31. The "M"-shaped structure provides support in multiple directions to form multiple triangular structures, so that the entire anti-smash bracket 3 can better maintain its shape when subjected to external force and is not easily deformed. It can also effectively prevent deformation or damage caused by external force, thereby ensuring the structural stability of the anti-smash bracket 3 under complex stress conditions.

[0047] Furthermore, a reinforcing plate 34 is provided at the connection of the support frame 32, which can effectively disperse the stress concentration at the connection, prevent the connection part from being damaged due to excessive force, and enhance the strength and durability of the overall structure. Moreover, the firmness of the connection point of the support frame 32 is ensured by the provision of the reinforcing plate 34, further improving the stability of the anti-smash bracket 3 under dynamic load.

[0048] Through the combined design of the trapezoidal frame structure, the "M"-shaped support frame 32 and the reinforcement plate 34, the anti-smash bracket 3 has high strength and stability, can effectively resist external smashing and impact, and maintains the characteristics of lightness and compactness, without adding unnecessary weight or taking up too much space.

[0049] The upper end of the anti-smashing bracket 3 is provided with a groove 6 that cooperates with the headrest on the seat back 21, so as to avoid collision between the seat back 21 and the anti-smashing bracket 3 when the seat back 21 and the anti-smashing bracket 3 rotate between them.

[0050] The lower part of the anti-smashing bracket 3 is rotatably provided with an electric telescopic rod 7, and the output end of the electric telescopic rod 7 is rotatably connected to the chair back 21. Through the arrangement of the electric telescopic rod 7, the angle of the seat portion 2 can be adjusted by the extension and retraction of the electric telescopic rod 7.

[0051] Furthermore, a reinforcing rod 33 connected to the support frame 32 and corresponding to the electric telescopic rod 7 is provided in the outer support frame 31. By setting the reinforcing rod 33, the structural strength of the connection between the electric telescopic rod 7 and the support frame 32 is improved. At the same time, a reinforcing plate 2 is provided at the connection between the reinforcing rod 33 and the support frame 32 corresponding to the electric telescopic rod 7 to realize a rotational connection with the electric telescopic rod 7.

[0052] During operation, since both the rotating structure 1 23 and the rotating structure 2 5 use electric angle adjusters, they can be controlled by an electronic control unit (ECU) connected to the rotating structure 1 23, the rotating structure 2 5 and the electric telescopic rod 7 at the armrest of the seat, and can be operated by physical buttons, touch screens or voice commands;

[0053] Specifically, the extension of the electric telescopic rod 7 is controlled by the control button of the electronic control unit, and the rotation of the rotating structure 1 23 and the rotating structure 2 5 are coordinated and controlled to rotate, thereby adjusting the angle of the seat part 2.

[0054] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
