Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, specifically to an improved multifunctional automotive seat back panel. Background Technology

[0002] Car seats can be categorized by shape (split seats, bench seats); by function (fixed, removable, adjustable); and by seating capacity (single, double, multi-seater). Based on performance, seats have evolved from early fixed seats to multi-functional power-adjustable seats, including air-cushioned seats, electric seats, stereo seats, recovery seats, and finally electronically adjustable seats. A rotating backrest can be installed at the rear of the car seat to function as a table.

[0003] Currently, seat backrests only have a rotating connection between the backrest and the seat, and the backrest itself does not change. In the event of an accident while the car is in motion, the backrest can easily impact the passenger, posing a safety hazard. In addition, current backrests have limited functionality and cannot meet more needs. Summary of the Invention

[0004] In view of the shortcomings of existing technology, the back panel itself does not change. In the event of an accident while the car is in motion, the back panel is likely to impact the passenger, posing a safety hazard. The purpose of this invention is to provide an improved multi-functional car seat back panel.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An improved multi-functional car seat back panel includes a first plate and a second plate, an elastic body is provided between the first plate and the second plate, and a plate fixing member is provided between the bottom of the first plate and the second plate, the plate fixing member defining the included angle between the first plate and the second plate.

[0007] The plate fastener includes a first fixing plate and a second fixing plate. The first fixing plate is fixed to the bottom of the first plate or the second plate, and the first fixing plate is engaged with the second fixing plate.

[0008] When the first fixing plate is fixed to the bottom of the first plate, the second fixing plate supports the second plate.

[0009] When the first fixing plate is fixed to the bottom of the second plate, the second fixing plate supports the first plate.

[0010] Preferably, the second plate is horizontally arranged, and the first plate is inclined upward relative to the second plate, with the angle between the first plate and the horizontal plane being 10-15 degrees.

[0011] Preferably, the second plate is horizontally arranged, and the first plate is inclined downward relative to the second plate, with the angle between the first plate and the horizontal plane being 10-15 degrees.

[0012] Preferably, an adjusting member is formed between the first fixing plate and the second fixing plate, the adjusting member including an external gear disk and an internal gear ring;

[0013] The internal gear ring is fixedly connected to the first fixing plate, the external gear disk is fixedly connected to the external gear disk, and the internal gear ring and the external gear disk are fixedly connected by side insertion.

[0014] Preferably, the external gear disk and the internal gear ring have the same convex tooth structure, and the height of the contact surface between the external gear disk and the internal gear ring is greater than one-quarter and less than one-half of the convex tooth.

[0015] Preferably, the second fixing plate at the contact end with the external gear disk is configured with a stepped structure, and the thickness of the second fixing plate at the contact end with the external gear disk is less than the thickness of the second fixing plate at the contact end away from the external gear disk.

[0016] Preferably, the elastic body has fixing straps at equal intervals inside, with its two ends respectively connecting to the first plate and the second plate.

[0017] Preferably, the first plate has holes, and a deformable storage rack is provided in the holes. The storage rack includes connecting straps, guide rods and a base plate. Multiple connecting straps are fixed along the perimeter of the base plate. The guide rods are fixed in the first plate to guide the connecting straps. The other end of the connecting straps is connected to a fixing strap.

[0018] Preferably, a rotating cover is provided inside the first plate at the location of the hole, and a rotating shaft is provided between the rotating cover and the first plate;

[0019] The rotating cover is configured as a fan-shaped structure, and multiple rotating covers are provided, forming a circular structure among the multiple rotating covers.

[0020] Preferably, the periphery of the first plate and the second plate is provided with an elastic protective layer, and the elastic protective layer and the elastomer are an integral structure.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By setting up a first plate and a second plate, the two can be bent quickly. When the car is involved in an accident and the passengers inside move, the force will be applied to the second plate. When the instantaneous impact is transmitted to the connection between the first plate and the second plate, the fixing device between the first plate and the second plate can be misaligned or broken, thereby causing the first plate to bend relative to the second plate, thus avoiding the back panel impacting the passengers and making the passengers safer.

[0023] 2. The back panel is equipped with storage shelves, which can be adjusted to different shapes according to actual needs, making the back panel more versatile.

[0024] 3. The storage rack is connected to the first and second panels as a whole, which makes the back panel more stable and less prone to damage to the main body after being subjected to external forces, resulting in better actual use. Attached Figure Description

Detailed Implementation

[0035] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0036] Example 1

[0037] like Figure 1-2 As shown, an improved multi-functional car seat back panel includes a first plate 10 and a second plate 20. An elastic body 30 is provided between the first plate 10 and the second plate 20. A plate fixing member 80 is provided between the bottom of the first plate 10 and the second plate 20. The plate fixing member 80 limits the included angle between the first plate 10 and the second plate 20.

[0038] like Figure 3 As shown, the plate fastener 80 includes a first fixing plate 81 and a second fixing plate 82. The first fixing plate 81 is fixed to the bottom of the first plate 10 or the second plate 20. The first fixing plate 81 engages with the second fixing plate 82, which allows the first fixing plate 81 and the second fixing plate 82 to be quickly connected, thereby facilitating the quick formation of the first plate 10 and the second plate 20 into the shape structure that needs to be fixed. When an impact force occurs between the first plate 10 and the second plate 20, the connection position between the first fixing plate 81 and the second fixing plate 82 will be misaligned or broken, thereby causing the first plate 10 and the second plate 20 to bend.

[0039] When the first fixing plate 81 is fixed to the bottom of the first plate 10, the second fixing plate 82 supports the second plate 20;

[0040] When the first fixing plate 81 is fixed to the bottom of the second plate 20, the second fixing plate 82 supports the first plate 10.

[0041] The second plate 20 is set horizontally, and the first plate 10 is set inclined upward relative to the second plate 20. The angle between the first plate 10 and the horizontal plane is 10-15 degrees.

[0042] Specifically, the first plate 10 is first rotated to an upward tilted position, and then the second plate 20 is rotated to a horizontal position. The position between the first plate 10 and the second plate 20 is restricted by the plate fixing member 80. The plate fixing member 80 is thin. When the second plate 20 is subjected to an external force impact, the connection end between the first plate 10 and the second plate 20 will bend or break, causing the first plate 10 and the second plate 20 to form a folding phenomenon. Therefore, the back panel made of this structure will not cause impact to the passengers.

[0043] In addition, the back panel of this structure is suitable for external force impacting the second plate 20. When the impact force occurs obliquely upward, the second plate 20 can exert an oblique downward impact force on the first plate 10, which can cause the first plate 10 and the second plate 20 to bend quickly, thus avoiding injury to passengers.

[0044] An elastic body 30 is provided between the first plate 10 and the second plate 20. The connection of the elastic body 30 allows the first plate 10 and the second plate 20 to be easily bent, and also allows the first plate 10 and the second plate 20 to be connected as one unit. When the first plate 10 and the second plate 20 need to be reset, they can quickly return to their original positions.

[0045] Example 2

[0046] like Figure 1 and Figure 4 As shown, an improved multi-functional car seat back panel includes a first plate 10 and a second plate 20. An elastic body 30 is provided between the first plate 10 and the second plate 20. A plate fixing member 80 is provided between the bottom of the first plate 10 and the second plate 20. The plate fixing member 80 limits the included angle between the first plate 10 and the second plate 20.

[0047] The plate fixing component 80 includes a first fixing plate 81 and a second fixing plate 82. The first fixing plate 81 is fixed to the bottom of the first plate 10 or the second plate 20, and the first fixing plate 81 is engaged with the second fixing plate 82.

[0048] When the first fixing plate 81 is fixed to the bottom of the first plate 10, the second fixing plate 82 supports the second plate 20;

[0049] When the first fixing plate 81 is fixed to the bottom of the second plate 20, the second fixing plate 82 supports the first plate 10.

[0050] like Figure 5 As shown, the second plate 20 is set horizontally, and the first plate 10 is set inclined downward relative to the second plate 20. The angle between the first plate 10 and the horizontal plane is 10-15 degrees.

[0051] Specifically, the first plate 10 is first rotated to a downward tilting position, and then the second plate 20 is rotated to a horizontal position. The position between the first plate 10 and the second plate 20 is restricted by the plate fixing member 80. The plate fixing member 80 is thin. When the second plate 20 is subjected to an external force impact, the connection end between the first plate 10 and the second plate 20 will bend or break, causing the first plate 10 and the second plate 20 to form a folding phenomenon. Therefore, the back panel made of this structure will not cause impact to the passengers.

[0052] In addition, the back panel of this structure is suitable for external impact on the second plate 20. When the impact force occurs obliquely downward, the second plate 20 can exert an upward impact force on the first plate 10 in an oblique direction, which can cause the first plate 10 and the second plate 20 to bend quickly, thus avoiding injury to passengers.

[0053] The first plate 10 has an angle of 10-15 degrees with respect to the horizontal plane, which makes it convenient for users to place items on the seat back.

[0054] Example 3

[0055] Based on Example 1 or Example 2, such as Figure 6 As shown, an adjusting member 83 is formed between the first fixing plate 81 and the second fixing plate 82. The adjusting member 83 includes an external gear disk 831 and an internal gear ring 832.

[0056] The internal gear ring 832 is fixedly connected to the first fixing plate 81, the external gear disk 831 is fixedly connected to the external gear disk 831, and the internal gear ring 832 and the external gear disk 831 are fixedly connected by side insertion.

[0057] Specifically, the lateral engagement between the external gear disk 831 and the internal gear ring 832 connects them into a single unit, thus fixing the connection between the outer first fixing plate 81 and the second fixing plate 82. When the second plate 20 is subjected to external force, the first plate 10 and the second plate 20 bend, causing the external gear disk 831 and the internal gear ring 832 to separate or break, resulting in a rapid bending phenomenon between the first plate 10 and the second plate 20. This reduces the overall volume of the back panel, preventing the back panel from restricting the seating space and trapping people in the event of a vehicle accident. It also prevents the back panel from impacting passengers, greatly improving the safety of passengers.

[0058] Example 4

[0059] Based on Example 3, the external gear disk 831 and the internal gear ring 832 have the same convex tooth structure, and the contact surface height between the external gear disk 831 and the internal gear ring 832 is greater than one-quarter of the convex tooth and less than one-half of the convex tooth.

[0060] With this structural design, on the one hand, when fixing the external gear disk 831 and the internal gear ring 832, the relative position between the external gear disk 831 and the internal gear ring 832 can be quickly defined. On the other hand, when the first plate 10 and the second plate 20 need to be bent, due to the small contact area between the external gear disk 831 and the internal gear ring 832, the convex teeth on the external gear disk 831 and the internal teeth on the internal gear ring 832 can impact each other, causing them to separate or misalign, thereby causing the first plate 10 and the second plate 20 to bend.

[0061] Furthermore, the second fixing plate 82 is configured with a stepped structure at the contact end with the external gear disk 831, and the thickness of the second fixing plate 82 at the contact end with the external gear disk 831 is less than the thickness of the second fixing plate 82 at the contact end away from the external gear disk 831.

[0062] With this structural design, the contact area between the second fixed plate 82 and the external gear disk 831 can be thinner. When subjected to a sudden impact from an external force, this part of the structure is more likely to break, thereby allowing the first plate 10 and the second plate 20 to be bent quickly. This completely avoids the phenomenon that the first plate 10 and the second plate 20 cannot be bent, resulting in better actual performance.

[0063] Example 5

[0064] Based on Example 4, such as Figure 8 As shown, the elastic body 30 has fixing straps 31 at equal intervals inside, with the two ends respectively connecting the first plate 10 and the second plate 20. This makes the connection between the first plate 10 and the second plate 20 more stable, and the two will not separate at all.

[0065] Example 6

[0066] Based on Example 5, such as Figure 1 and Figure 7 As shown, the first plate 10 has holes, and a deformable storage rack 50 is installed in the holes. The storage rack 50 includes connecting straps 52, guide rods 53 and a base plate 54. Multiple connecting straps 52 are fixed along the periphery of the base plate 54. The guide rods 53 are fixed in the first plate 10 to guide the connecting straps 52. The other end of the connecting straps 52 is connected to a fixing strap 31. With this structure, the storage rack 50 allows the base plate 54 to be engaged in the holes in the first plate 10, and the fixing strap 31 is stored in the holes, so that the first plate 10 forms a flat state.

[0067] When it is necessary to use the storage rack 50 to store cups as long cylindrical objects, the base plate 54 can be removed from the hole, and the base plate 54 can be pulled and limited by the connecting strap 52, so that the items can be supported by the base plate 54, making the seat back panel more versatile.

[0068] The other end of the connecting strap 52 is connected to the fixing strap 31, which makes the connecting strap 52 and the fixing strap 31 form a whole. The storage rack 50 and the second plate 20 are integrated, making the shape and position of the storage rack 50 more stable and preventing it from becoming loose or detached.

[0069] Furthermore, a rotating cover 51 is provided inside the first plate 10 at the hole location, and a rotating shaft is provided between the rotating cover 51 and the first plate 10, so that the top of the first plate 10 can be closed and sealed.

[0070] Furthermore, the rotating cover 51 is configured as a fan-shaped structure, and multiple rotating covers 51 are provided, forming a circular structure among the multiple rotating covers 51.

[0071] Example 7

[0072] Based on Example 6, such as Figure 8 As shown, the first plate 10 and the second plate 20 are provided with an elastic protective layer 60 around their periphery. The elastic protective layer 60 and the elastic body 30 are an integral structure. On the one hand, it can provide peripheral protection for the first plate 10 and the second plate 20, so that passengers will not bump into the first plate 10 and the second plate 20 when riding, thus improving the safety of passengers. On the other hand, it can make the connection between the first plate 10 and the second plate 20 more stable. The whole formed by the first plate 10 and the second plate 20 can be used as a table when objects are placed.

[0073] A hinge 40 is provided on one side of the first plate 10, which is connected to the car seat through the hinge 40, so that the first plate 10 can rotate. When the back panel is not needed, the back panel can be rotated to the rear of the seat, and the back panel is limited by the locking mechanism at the rear of the seat.

[0074] The bottom of the first plate 10 is fixed with a fixing clip 70 that restricts the position of the first fixing plate 81, thereby forming an integral structure between the first fixing plate 81 and the first plate 10.

[0075] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
