[0059] According to the following Figures 1 to 7 The automobile seat of the utility model is described in detail.

[0060] In this embodiment, if Figure 6 and Figure 7 As shown, the vehicle seat includes a high-position locking mechanism 100 and a seat back 200. Figures 1 to 7 As shown, the high-position locking mechanism 100 includes a locking active component 1 and a locking passive component 2. The locking active component 1 includes a mounting member 11, a first locking member 12 and an elastic member 13. The first locking member 12 is rotatably connected to the mounting member 11, and the elastic member 13 is installed on the mounting member 11. The locking passive component 2 includes a connected guide seat 21 and a second locking member 22. The mounting member 11 and the guide seat 21 are movably connected.

[0061] One of the locking active component 1 and the locking passive component 2 is linked to the seat back 200, and the other is installed on the automobile body 300. Specifically, in one embodiment, Figure 1 and Figure 6 As shown, when assembling the high-position locking mechanism 100, the locking active component 1 is linked with the seat back 200, and the locking passive component 2 is installed on the automobile body 300, so that the locking passive component 2 is fixed, and the locking active component 1 can move relative to the locking passive component 2 driven by the seat back 200 to achieve angle adjustment. In another embodiment, when assembling the high-position locking mechanism 100, the locking passive component 2 is linked with the seat back 200, and the locking active component 1 is installed on the automobile body 300, so that the locking active component 1 is fixed, and the locking passive component 2 can move relative to the locking active component 1 driven by the seat back 200 to achieve angle adjustment.

[0062] like Figure 1 and Figure 5As shown, when the high-position locking mechanism 100 is in the initial state, the elastic member 13 keeps the first locking member 12 in the initial position, so that the first locking member 12 is interlocked with the second locking member 22, so that the first locking member 12 and the second locking member 22 cannot produce relative displacement, thereby locking the seat back 200 and the automobile body 300 through the high-position locking mechanism 100, thereby locking the seat back 200. Among them, the initial position of the first locking member 12 is also the locking position A.

[0063] like Figure 1 , Figures 5 to 7 As shown, when the angle needs to be adjusted, the first locking member 12 rotates relative to the mounting member 11 under external force, and the first locking member 12 is disengaged from the second locking member 22 due to the rotation, and unlocking is achieved. At this time, the first locking member 12 rotates to the unlocking position B. During the rotation of the first locking member 12, the elastic member 13 is compressed. After unlocking, the first locking member 12 and the second locking member 22 can produce relative displacement under external force, so that one of the locking active component 1 and the locking passive component 2 can move relative to the other, and under the guidance of the guide seat 21, one rotates around the first mounting axis 400 of the seat back 200, so that the user can turn the seat back 200.

[0064] When the seat back 200 is rotated to the desired angle, the external force applied to the first locking member 12 is released, and then, under the restoring elastic force of the elastic member 13, the first locking member 12 is rotated and reset to re-lock the seat back 200, thereby adjusting the angle θ. Figure 7 As shown, the angle θ represents the angle between the seat back 200 at the initial position and the seat back 200 after the angle adjustment.

[0065] By adopting the above technical solution, the high-position locking mechanism 100 realizes the locking or unlocking function through the rotational cooperation of the locking active component 1 and the locking passive component 2, and in the unlocking mode, the angle adjustment function of the seat back 200 is realized by moving one of the locking active component 1 and the locking passive component 2 relative to the other. The high-position locking mechanism 100 of this solution has fine adjustment of the gear position, and compared with the solution of the prior art CN113022392A, it has the advantages of simple structure, few parts, reliable locking strength and low processing cost, does not require the cooperation of multiple elastic parts, and the assembly gap is easy to control.

[0066] It should be understood that, in this article, "one" refers to the component of the locking active component 1 and the locking passive component 2 that is linked to the seat back 200, and "the other" refers to the component of the locking active component 1 and the locking passive component 2 that is installed on the automobile body 300.

[0067] In one embodiment, if Figure 6As shown, the high-position locking mechanism 100 includes a switch and a pull wire 4 that are linked to each other. The pull wire 4 is connected to the first locking member 12. The user pulls the pull wire 4 through the switch, and the tension of the pull wire 4 overcomes the elastic force of the elastic member 13. Figure 5 As shown, the pull wire 4 applies a force F to the first locking member 12, pulling the first locking member 12, so that the first locking member 12 rotates from the locking position A to the unlocking position B, thereby achieving unlocking, which is convenient to operate.

[0068] In one embodiment, one of the active locking component 1 and the passive locking component 2 is linked to an upper portion of the seat back 200 , for example, to a side of the top of the seat back 200 close to the vehicle body 300 .

[0069] In one embodiment, if Figure 6 As shown, a backrest lock 201 is provided at the upper portion of the seat back 200 close to the automobile body 300 , and one of the locking active component 1 and the locking passive component 2 is linked with the backrest lock 201 to achieve linkage with the seat back 200 .

[0070] In one embodiment, if Figure 1 and Figure 6 As shown, since the guide seat 21 needs to provide a guiding function, the guide seat 21 needs to have a certain length, that is, the length of the locking passive component 2 is longer than the length of the locking active component 1. In this way, in this solution, the locking passive component 2 is assembled with the automobile body 300. Since the locking passive component 2 is longer, it is conducive to the stable assembly of the high-position locking mechanism 100. In addition, the locking active component 1 is linked with the seat back 200, and the mounting member 11 of the locking active component 1 is movably connected to the guide seat 21. Since the locking active component 1 has a compact structure, the locking active component 1 is more flexible to move. After unlocking, the seat back 200 drives the locking active component 1 to move under external force, and under the guidance of the guide seat 21, the locking active component 1 rotates around the first mounting axis 400 of the seat back 200 to adjust the angle of the seat back 200.

[0071] In one embodiment, if Figure 1 As shown, under the elastic force of the elastic member 13, the first locking member 12 and the second locking member 22 are engaged with each other, and interlocking is achieved through the engagement, and the structure is simple.

[0072] In one embodiment, if Figures 1 to 4As shown, the second locking member 22 is a long U-shaped structure, and the second locking member 22 includes two oppositely arranged toothed belts 221, each toothed belt 221 is provided with a plurality of evenly spaced convex teeth 2211, and a tooth groove 2212 is formed between two adjacent convex teeth 2211. The first locking member 12 is provided with a locking hole 1211, which is a long hole, and the locking hole 1211 is simultaneously engaged with a pair of convex teeth 2211 oppositely arranged on the two toothed belts 221 to improve the locking strength.

[0073] Furthermore, if Figure 2 As shown, the first locking member 12 includes a locking structure 121, which is a fence structure to form three locking holes 1211. Specifically, the locking structure 121 is in the form of a sheet, and the locking structure 121 also includes four parallel long bars 1212, and two adjacent locking holes 1211 are separated by the long bars 1212. When the first locking member 12 and the second locking member 22 are interlocked, the convex teeth 2211 are engaged in the corresponding locking holes 1211, and the long bars 1212 are engaged with the corresponding tooth grooves 2212 of the two toothed belts 221 at the same time. In this solution, the first locking member 12 has a simple structure, is easy to process, and can form a high-strength locking relationship with the second locking member 22.

[0074] Furthermore, if Figure 2 As shown, the locking structure 121 also includes a connecting plate 1213 and a connecting rod 1214. One end of the long rod 1212 is connected to the connecting plate 1213, and the other end is connected to the connecting rod 1214. In this way, the connecting plate 1213, the connecting rod 1214 and the four long rods 1212 form a locking structure 121 with a fence structure to ensure that the locking structure 121 has a high structural strength.

[0075] Of course, the number of locking holes 1211 is not limited to three, and similarly, the number of long bars 1212 is not limited to four. For example, the number of locking holes 1211 can be one, two, four or even more, and the number of long bars 1212 matches the number of locking holes 1211. Preferably, in order to simultaneously meet the purpose of structural strength and structural simplification, the number of locking holes 1211 is three.

[0076] In one embodiment, if Figures 1 to 3 As shown, the locking active component 1 includes a bushing 14, which is limited to the mounting member 11, and the bushing 14 is sleeved on the guide seat 21 and the two are slidably matched, that is, the guide seat 21 is assembled to the mounting member 11 through the bushing 14. In a specific embodiment, the bushing 14 includes a slide groove 141, and the guide seat 21 is plate-shaped, thin and light, and the guide seat 21 is slidably matched with the slide groove 141. Compared with the technical solution of directly assembling the guide seat 21 to the mounting member 11, this solution can reduce friction and noise during the sliding process of one of the locking active component 1 and the locking passive component 2.

[0077] Furthermore, if Figures 1 to 3 As shown, the cross-section of the bushing 14 is roughly C-shaped and forms a C-shaped slide groove 141. The opening of the slide groove 141 is opposite to the toothed belt 221 of the second locking member 22, and the protruding tooth 2211 is at least partially located outside the opening of the slide groove 141. In this way, the toothed belt 221 can be engaged with the locking structure 121 of the first locking member 12 and locked.

[0078] In one embodiment, if Figure 1 As shown, the locking active component 1 includes a pressing plate 15, which is connected to the mounting member 11 and forms a clamping cavity, in which the bushing 14 is clamped, and the bushing 14 is easy to assemble and firm. Figure 2 As shown, the pressing plate 15 is provided with a yielding structure 151, and the shape of the yielding structure 151 is a fence structure matching the locking structure 121. Specifically, as shown in FIG. Figure 2 and Figure 3 As shown, the yield structure 151 includes a yield hole 1511 and a fence rod 1512 which are arranged in sequence. When the first locking member 12 rotates to interlock with the second locking member 22, the long rod 1212 of the locking structure 121 passes through the yield hole 1511, and at the same time, the fence rod 1512 passes through the locking hole 1211, that is, the locking structure 121 of the first locking member 12 can pass through the yield structure 151 and interlock with the second locking member 22, thereby preventing the pressing plate 15 from interfering with the interlocking of the first locking member 12 and the second locking member 22.

[0079] In one embodiment, if Figure 1 and Figure 2 As shown, the mounting member 11 is provided with a card slot 111 and a first mounting hole 112, and the pressing plate 15 is provided with a card protrusion 152 and a second mounting hole 153, the card protrusion 152 and the second mounting hole 153 are respectively located on both sides of the bushing 14, the card protrusion 152 is carded in the card slot 111, and the first mounting hole 112 and the second mounting hole 153 are fixed by a first fastener 3, wherein the first fastener 3 includes but is not limited to rivets or screws. Of course, the mounting member 11 and the pressing plate 15 can also be fixed by welding.

[0080] Furthermore, if Figure 2 As shown, the main body 116 of the mounting member 11 is a flat plate structure, the main body 116 is connected to the pressing plate 15 and forms a clamping cavity for clamping the bushing 14 , and the clamping groove 111 and the first mounting hole 112 are arranged on the main body 116 .

[0081] In one embodiment, if Figure 1 and Figure 2 As shown, a recessed portion 154 is provided on one side of the pressing plate 15 facing the guide seat 21 , and the recessed portion 154 is used to accommodate the two toothed belts 221 of the second locking member 22 .

[0082] Furthermore, if Figure 1 and Figure 2 As shown, the opening of the bushing 14 is opposite to the recessed portion 154, and the bushing 14 has a certain flexibility. The side walls of the bushing 14 on both sides extend in the direction toward the pressing plate 15 to form a first flange 142, and the side walls at the opening of the bushing 14 extend in the direction toward the pressing plate 15 to form a second flange 143. The first flanges 142 on both sides clamp the side walls of the pressing plate 15, and the second flanges 143 on both sides extend into the recessed portion 154 and abut against the wall surface of the recessed portion 154 to ensure stable assembly between the bushing 14 and the mounting member 11 and the pressing plate 15.

[0083] In one embodiment, if Figure 1 and Figure 6 As shown, the locking active component 1 includes an adapter 16, which is used to be detachably connected to the backrest lock 201 of the seat back 200, thereby linking the locking active component 1 with the seat back 200. Further, the adapter 16 is a steel wire, and the adapter 16 and the pressing plate 15 are fixed by riveting or welding, and the adapter 16 is engaged with the lock tongue provided on the backrest lock 201. Of course, the setting of the adapter 16 is not limited to this, and the locking passive component 2 may also include an adapter (not shown in the figure), and the locking passive component 2 is linked with the backrest lock 201 through the adapter.

[0084] In one embodiment, if Figure 1 and Figure 2 As shown, the mounting member 11 is provided with a second mounting shaft 113, and the first locking member 12 is provided with two first connecting arms 122, and the two first connecting arms 122 are respectively rotatably connected to the second mounting shaft 113. The elastic member 13 is a torsion spring, and the elastic member 13 is sleeved on the second mounting shaft 113. One end of the elastic member 13 is pressed tightly on the first locking member 12, and the other end is pressed on the mounting member 11. Under the action of the elastic member 13, the locking structure 121 of the first locking member 12 passes through the yielding structure 151 of the pressing plate 15 and is engaged with the toothed belt 221 of the second locking member 22.

[0085] Furthermore, if Figure 1 and Figure 2 As shown, the mounting member 11 is provided with two second connecting arms 114 , and both ends of the second mounting shaft 113 are respectively mounted on the two second connecting arms 114 .

[0086] In one embodiment, if Figure 2 , Figure 3 and Figure 6As shown, a first connecting piece 115 is provided on one side of the mounting member 11, and the first connecting piece 115 is provided with a through hole 1151. A second connecting piece 123 is provided on one side of the first locking member 12, and the second connecting piece 123 is provided with a bayonet 1231. The pull wire 4 passes through the through hole 1151 and is clamped in the bayonet 1231. When the user pulls the pull wire 4 through the switch, the pull wire can apply a force F to the first locking member 12 through the bayonet 1231, as shown in FIG. Figure 5 As shown, under the pulling force F, the first locking member 12 rotates from the locking position A to the unlocking position B. It should be understood that the pull wire 4 can adopt the structure of the existing pull wire in the car, which will not be described in detail here.

[0087] In one embodiment, if Figure 1 As shown, the second locking member 22 is a long U-shaped structure, and the second locking member 22 is provided with two limiting posts 222, which are located on both sides of the toothed belt 221. The two limiting posts 222 are used to limit the limit value of the angle adjustment of the high-position locking mechanism 100, and prevent the locking active component 1 and the locking passive component 2 from being separated from each other. Specifically, the locking active component 1 and the seat back 200 are linked as an example for specific description. In the process of the locking active component 1 moving along the guide seat 21, if the locking active component 1 moves in one direction until the side wall of the pressing plate 15 abuts against one of the limiting posts 222, the locking active component 1 stops and cannot move further. If the locking active component 1 moves in the opposite direction until the side wall of the pressing plate 15 abuts against the other limiting post 222, the locking active component 1 stops and cannot move further.
