[0056] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0057] The present invention provides a backrest support 1000, such as Figure 1 - Figure 10 As shown, the backrest bracket 1000 includes a fixing assembly 10, a connecting member 20 and a locking member 30. The fixing assembly 10 includes a first connecting arm 11, a second connecting arm 12 and two hooks 13. The first connecting arm 11 is hollow inside, and the second connecting arm 12 is in the first direction (such as Figure 1 The first connecting arm 11 is provided with a plurality of connecting members 12 and 13, and the first connecting arm 11 and the second connecting arm 12 are respectively connected to two hooks 13 on opposite sides of the first direction. The second connecting arm 12 is movably connected to the first connecting arm 11 in the first direction so that the corresponding hook 13 moves in the first direction. The first connecting arm 11 is provided with an opening 111, and at least a portion of the second connecting arm 12 is exposed at the opening 111. The connecting member 20 is installed at the first connecting arm 11 for fixing the mobile terminal. The locking member 30 includes a plurality of connecting members 12 and 13. The invention comprises a wrench portion 31 and a rotating portion 32. The wrench portion 31 is located outside the first connecting arm 11 and is connected to the rotating portion 32. The rotating portion 32 is rotatably connected to the first connecting arm 11 and corresponds to the position of the opening 111. The rotating portion 32 includes an outer peripheral surface 321, which is arranged around the rotation centerline of the rotating portion 32 and has a protruding section 3211. The wrench portion 31 is used to drive the rotating portion 32 to rotate so that the protruding section 3211 can be screwed into the opening 111 and abut against the second connecting arm 12. The present application can solve the problem of cumbersome assembly and disassembly of the rear pillow bracket 1000 in the prior art. The locking assembly and disassembly operations of the rear pillow bracket 1000 are faster and more convenient, and the user experience is better.

[0058] Specifically, the second connecting arm 12 can move in a first direction relative to the first connecting arm 11, thereby adjusting the relative distance between the two hooks 13 to facilitate alignment and connection between the hooks 13 and the pillow rod. Furthermore, after the hooks 13 are aligned and connected to the pillow rod, the wrench portion 31 of the locking member 30 is swung, causing the rotating portion 32 to rotate along with it. The protruding section 3211 of the rotating portion 32 can be screwed into the opening 111 and abut against the second connecting arm 12 to restrict movement of the second connecting arm 12, ultimately completing the locking operation. Removal requires only a reverse operation. Compared to the prior art installation method using double nuts and knobs, the entire installation and removal process of the rear pillow bracket 1000 does not require multiple operations. Locking can be completed with a single operation of turning the locking member 30. This operation method is efficient and convenient, more in line with human operating habits, and provides better comfort, thereby enhancing the user experience.

[0059] In the present application, the location of the opening 111 can be adjusted as needed and is not limited here. For example, in the present application, the opening 111 is provided at the location where the first connecting arm 11 is adjacent to the second connecting arm 12. In this way, when the second connecting arm 12 moves relative to the first connecting arm 11, the locking member 30 is closer to the hook 13 connected to the second connecting arm 12, and the force applied by the locking member 30 on the second connecting arm 12 will be closer to the hook 13 connected to the second connecting arm 12, reducing the length of the force arm, thereby improving the stability of the connection between the second connecting arm 12 and the first connecting arm 11, and preventing the second connecting arm 12 from shifting relative to the first connecting arm 11.

[0060] It is worth mentioning that, through the above embodiment, after the user completes the alignment connection between the hook 13 and the pillow rod, the user can also turn the locking member 30, which further optimizes the user experience and makes the operation smoother and more convenient.

[0061] In the present application, the first connecting arm 11 is hollow inside and can be in any shape, which is not limited here. For example, in the present application, the cross section of the first connecting arm 11 is in the shape of a square tube.

[0062] There are various ways to configure the locking member 30 so that it is rotatably connected to the first connecting arm 11, which are not limited here. For example, the rotation centerline of the rotating portion 32 of the locking member 30 can be arranged at an angle to the first direction. Specifically, the rotation centerline of the rotating portion 32 of the locking member 30 can be perpendicular to the first direction. In this way, the user can lock the locking member 30 by moving it left or right. In another example, the rotation centerline of the rotating portion 32 of the locking member 30 can be parallel to the first direction. In this way, the user can lock the locking member 30 by moving it up or down.

[0063] Reference Figure 6 、 Figure 7 as well as Figure 11 In one embodiment, the rear headrest bracket 1000 further includes a snap-fit ​​structure 40, which includes a snap-fit ​​block 41 and a snap-fit ​​slot 42. The first connecting arm 11 includes a first wall 112 adjacent to the opening 111. The first wall 112 is provided with either the snap-fit ​​slot 42 or the snap-fit ​​block 41. The rotating portion 32 is provided with the other of the snap-fit ​​slot 42 or the snap-fit ​​block 41. When the protruding section 3211 abuts the second connecting arm 12, the snap-fit ​​block 41 engages with the snap-fit ​​slot 42. In this manner, the snap-fit ​​block 41 cooperates with the snap-fit ​​slot 42 to limit the position of the locking member 30, maintaining the protruding section 3211 in abutment with the second connecting arm 12. This prevents the locking member 30 from being accidentally unlocked due to external forces, such as vehicle jolts during driving, which could cause the locking member 30 to lose its position. This improves the reliability of the overall structure.

[0064] In one embodiment, two engaging blocks 41 are provided, spaced apart in the rotational direction on the rotating portion 32. Both engaging blocks 41 can engage with the engaging slots 42. Thus, one engaging block 41 can limit the locking position of the locking member 30 to prevent accidental unlocking. The other engaging block 41 can limit the unlocking position of the locking member 30 to prevent the locking member 30 from swinging, ensuring that the relative movement between the second connecting arm 12 and the first connecting arm 11 is not disturbed.

[0065] In addition, by implementing the above-mentioned embodiment, before the snap-in block 41 is engaged with the snap-in slot 42, the snap-in block 41 will first contact the rotating portion 32 or the first wall 112, thereby generating a certain damping force. After the snap-in block 41 is engaged with the snap-in slot 42, the damping feeling disappears, allowing the user to directly perceive whether the locking member 30 is unlocked or locked in place through touch, making the operation more intuitive and improving the overall user experience.

[0066] In one embodiment, two snap structures 40 are provided, and the two snap structures 40 are symmetrically arranged on both sides of the rotating portion 32. In this way, when in the locked position or the unlocked position, the locking member 30 is subjected to a more balanced force and is less likely to deviate, thereby improving the reliability and stability of the connection.

[0067] Reference Figure 9 and Figure 11 In one embodiment, the protruding section 3211 is an arcuate protrusion extending circumferentially along the outer peripheral surface 321. The second connecting arm 12 includes a first surface wall 121 facing the opening 111. The first surface wall 121 has a curved surface 1211 that matches the arcuate protrusion, and the curved surface 1211 extends along the first side. This provides smoother surfaces for the curved protrusion and the curved surface 1211, reducing resistance when they contact each other. This facilitates smoother rotation of the protruding section 3211 into a position corresponding to the curved surface 1211 during rotation of the rotating portion 32, facilitating a more streamlined locking process.

[0068] Reference Figure 3 and Figure 4 In one embodiment, the first connecting arm 11 is provided with two connecting ears 113 protruding from the outside. The two connecting ears 113 are located on either side of the opening 111, and the rotating portion 32 is rotatably connected between the two connecting ears 113. This arrangement improves the stability of the rotational connection of the rotating portion 32 because both sides of the rotating portion 32 are connected to the connecting ears 113, thereby enhancing the stability of the overall structure.

[0069] Specifically, the rotating portion 32 is provided with a connecting shaft, and the rotating portion 32 is rotatably connected to the two connecting ears 113 respectively through the connecting shaft.

[0070] Reference Figure 12 and Figure 13In one embodiment, the first connecting arm 11 includes a locking sleeve 114 and a first hollow tube 115. The first hollow tube 115 extends in a first direction. The locking sleeve 114 is connected to one end of the first hollow tube 115. The other end of the hollow tube is connected to one of the hooks 13. The opening 111 is provided in the locking sleeve 114, and the locking member 30 is rotatably connected to the locking sleeve 114. This arrangement, through the separate component design, can effectively reduce the difficulty and cost of manufacturing the first connecting arm 11, reducing the manufacturing cost and making it more suitable for mass production.

[0071] In one embodiment, the first hollow tube 115 and the locking sleeve 114 are detachably connected, so as to facilitate the installation of other components.

[0072] There are many ways to detachably connect the first hollow tube 115 and the lock sleeve 114. For example, there are snap connections and threaded connections. Figure 13 In the present application, the first hollow tube 115 and the locking sleeve 114 are connected by a snap-fit ​​connection. A snap-fit ​​block 1143 is provided on the outer peripheral wall of the locking sleeve 114, and a snap-fit ​​groove (not shown in the figure) is provided on the inner wall of the first hollow tube 115. The locking sleeve 114 is inserted into the first hollow tube 115, and the snap-fit ​​block 1143 is snap-fitted into the snap-fit ​​groove.

[0073] Similarly, in one embodiment, the connection method between the first hollow tube 115 and one of the hooks 13 , and the connection method between the second connecting arm 12 and the other hook 13 are consistent with those in the above embodiment, and are not repeated here.

[0074] Refer again Figure 13 In one embodiment, the locking sleeve 114 includes a connecting portion 1141 and an inserting portion 1142. The connecting portion 1141 is exposed outside the first hollow tube 115, and the inserting portion 1142 is inserted into the first hollow tube 115. The opening 111 is set at the connecting portion 1141. One end of the second connecting arm 12 is located in the first hollow tube 115, and the other end is sequentially passed through the inserting portion 1142 and the connecting portion 1141. A limiter (not shown in the figure) is provided at one end of the second connecting arm 12. The limiter can abut against the inserting portion 1142 to prevent the second connecting arm 12 from directly detaching from the first connecting arm 11, making the overall structure more solid.

[0075] Reference Figure 14In one embodiment, the second connecting arm 12 is hollow. The rear headrest bracket 1000 further includes an elastic member 90 located within the second connecting arm 12. One end of the elastic member 90 is connected to the second connecting arm 12, while the other end extends beyond the second connecting arm 12 and connects to the first connecting arm 11. This arrangement ensures that the second connecting arm 12 always tends to move toward the first connecting arm 11. When the second connecting arm 12 is moved away from the first connecting arm 11 by an external force, the elastic member 90 accumulates energy. After the two hooks 13 are connected to their respective headrest rods, the elastic member 90 uses this force to maintain the two hooks 13 in contact with the headrest rod, enhancing the stability of the fixed connection. Furthermore, when the two hooks 13 are released from the headrest rod and the locking member 30 is in the unlocked position, the elastic member 90 releases energy, allowing the second connecting arm 12 to quickly return to its original position within the first connecting arm 11, making storage more convenient. Specifically, the elastic member 90 is a tension spring, the second connecting arm 12 is a second hollow tube, and the cross section of the second connecting arm 12 is also in the shape of a square tube.

[0076] In the above embodiment, the two ends of the tension spring can be connected to the first connecting arm 11 and the second connecting arm 12 in various ways. For example, in this application, a latch 122 is inserted into the interior of the first connecting arm 11, and one end of the tension spring is hooked onto the latch 122. Similarly, the other end of the tension spring is connected to the second connecting arm 12 via another latch 122.

[0077] It is worth mentioning that since the second connecting arm 12 is hollow inside, the elastic member 90 is completely hidden in the first connecting arm 11 and the second connecting arm 12, and the overall appearance of the rear pillow bracket 1000 is also more beautiful.

[0078] Reference Figure 15 and Figure 16 In one embodiment, the rear pillow support 1000 further includes a sliding seat 50. In the first direction, the sliding seat 50 is provided with a sliding hole 51. The sliding hole 51 is mounted on the outside of the first connecting arm 11, so that the sliding seat 50 is slidably connected to the first connecting arm 11. The connecting member 20 is mounted on the outside of the sliding seat 50. This arrangement allows the connecting member 20 to slide on the first connecting arm 11, allowing the user to adjust the relative position of the mobile terminal in the first direction, meeting different user needs and improving the applicability of the product.

[0079] Reference Figure 17 In one embodiment, a slider 52 is provided on the wall of the sliding hole 51, and a slide groove 116 is provided on the first connecting arm 11. The slide groove 116 extends in the first direction, and the slider 52 is accommodated in the slide groove 116. This improves the connection stability between the sliding seat 50 and the first connecting arm 11, ensuring smoother sliding. Furthermore, the slide groove 116 can limit the slider 52, thereby preventing the sliding seat 50 from separating from the first connecting arm 11.

[0080] Reference Figure 18 and Figure 19 In one embodiment, the rear headrest support 1000 further includes a locking button 60, which includes a knob portion 61 and a resisting portion 62. The knob portion 61 is located outside the sliding seat 50 and is connected to one end of the resisting portion 62. The other end of the resisting portion 62 extends through the wall of the sliding hole 51. The resisting portion 62 is movably connected to the sliding seat 50 so that when the knob portion 61 is rotated, the other end of the resisting portion 62 resists the first connecting arm 11. With this arrangement, simply by rotating the knob portion 61, the resisting portion can be pressed against the first connecting arm 11. The frictional contact between the two restricts movement of the sliding seat 50 relative to the first connecting arm 11, thereby locking the sliding seat 50. This convenient and quick adjustment and locking method provide a better user experience.

[0081] For example, in this embodiment, the abutting portion 62 is threadedly connected to the sliding seat 50 , so that the knob portion 61 rotates to drive one end of the abutting portion 62 to abut against the first connecting arm 11 .

[0082] In one embodiment, a receiving groove 511 is provided in the wall of the sliding hole 51, and the other end of the abutting portion 62 extends through the bottom of the receiving groove 511. The rear pillow bracket 1000 also includes a cushion 70, which is received in the receiving groove 511. The other end of the abutting portion 62 is connected to the cushion 70 so that the cushion 70 abuts against the first connecting arm 11. With this arrangement, the receiving groove 511 can limit the cushion 70, and when the sliding seat 50 moves, it can drive the cushion 70 to move with it. The cushion 70 is soft and can better fit the first connecting arm 11, increasing contact friction and enhancing connection stability. In addition, the cushion 70 can prevent scratches on the surface of the first connecting arm 11, thereby improving the durability of the overall structure.

[0083] Reference Figure 20 In one embodiment, the rear headrest support 1000 further includes a swing arm 80, one end of which is rotatably connected to the sliding seat 50 and the other end of which is connected to the connecting member 20. The rotation axis of the swing arm 80 is perpendicular to the first direction, so that when the swing arm 80 rotates toward the first connecting arm 11, the connecting member 20 can be retracted to one side of the first connecting arm 11. In this way, the swing arm 80 not only increases the adjustment range of the connecting member 20 but also can be retracted to one side of the first connecting arm 11 when the user does not need to use it, thus reducing the external space occupied.

[0084] In one embodiment, the connecting member 20 is rotatably connected to the swing arm 80 to further increase the adaptability adjustment range.

[0085] Reference Figure 1In one embodiment, both hooks 13 are equipped with silicone pads 132, which are used to conform to the pillow rod. The softness of the silicone pads 132 provides a better fit, ensuring closer contact between the hooks 13 and the pillow rod, and increasing the stability of the connection. Furthermore, the silicone pads 132 provide a certain cushioning effect, effectively preventing the mobile terminal from shaking after being secured.

[0086] In one embodiment, both hooks 13 have a hollow structure 131 , so that the weight of the hooks 13 can be effectively reduced while ensuring the structural strength, making the entire rear pillow bracket 1000 lighter and easier to carry.
