[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] As attached Figure 1 -Attached Fig. 9 The clamp arm extension structure of a vehicle-mounted neck pillow and headrest fixing device shown in the figure includes a clamp arm body 1, the clamp arm body 1 includes a clamp arm 11, an extension arm 12 and a locking mechanism, the clamp arm 11 can be set as a left clamp arm or a right clamp arm, the extension arm 12 is used to connect an extension bracket, such as a mobile phone fixing bracket or a tablet computer fixing bracket, etc., a mounting groove 20 is opened on the clamp arm 11, and the locking mechanism is arranged in the mounting groove 20, and the extension arm 12 is connected to the clamp arm 11 in a horizontal or vertical direction. In this embodiment, the extension arm 12 is arranged on the clamp arm 11 in a horizontal direction, and the locking mechanism is used to lock the rotational state of the extension arm 12 and unlock the locked state.
[0029] In this way, when the locking mechanism is in the locked state and unlocked, the extension arm 12 can rotate left and right. When the locking mechanism is in the rotating state and locked, the rotation direction or angle of the extension arm 12 is fixed. By arranging the extension arm 12 on the clamp arm, the function of the headrest and neck pillow fixing device can be easily expanded, which effectively enriches the use scenarios of the product.
[0030] In some embodiments, as shown in the attached Figure 3-8As shown, the locking mechanism includes a lock plate 101, a button body 102 and at least one spring 103. One end of the extension arm 12 is bent downward and passes through the mounting slot 20 on the clamp arm 11 to connect with the lock plate 101. The lock plate 101 is fixedly connected to the extension arm 12. The button body 102 is located below the lock plate 101. The spring 103 is arranged on one side of the button body 102. The button body 102 is pressed and movably connected with the mounting slot 20. The lock plate 101 is a cylindrical structure. The outer ring of the lock plate 101 is provided with a tooth pattern. One end of the button body 102 is provided with an arc-shaped or fan-shaped boss 100, and the inner side surface of the boss 100 is provided with a toothed tooth 2 30. When the extension arm 12 is in a locked state of rotation, the toothed tooth 2 30 on the boss 100 contacts and meshes with the toothed tooth 1 40 on the lock disk 101. One side of the mounting groove 20 has an opening 201, and the end of the button body 102 opposite to the arc-shaped boss 100 extends outward through the opening 201 to facilitate the user to press the button body 102.
[0031] In some embodiments, as shown in the attached Figure 3 As shown, a limiting hole 1021 is provided on the button body 102 at a position corresponding to the positioning column 116, the length dimension of the limiting hole 1021 is greater than the diameter dimension of the positioning column 116, the limiting hole 1021 is arranged along the length direction of the button body 102, and the positioning column 116 is located in the limiting hole 1021. By arranging the positioning column 116 and the limiting hole 1021, the stroke of the button body 102 can be limited, and at the same time, the button body 102 can be prevented from shaking left and right. A mounting seat 1022 is provided on the button body 102, one end of the spring 103 is connected to the mounting seat 1022, and the other end of the spring 103 is abutted against the inner wall of the opposite mounting groove 20, forming an elastic pressing state of the button body 102, pressing the button body 102, and the tooth pattern 2 30 on the button body 102 disengages from the tooth pattern 1 40 on the lock disk 101, and the locked state of the extension arm 12 is unlocked.
[0032] In this way, when the button body 102 is pressed, the button body 102 slides backward along the opening 201, and the spring 103 is compressed and deformed. When the button body 102 slides to one end of the limiting hole 1021 and contacts the positioning column 116, the locking state of the locking mechanism is unlocked, and the button body 102 is released. Under the resetting force of the spring 103, the button body 102 is reset synchronously.
[0033] In some embodiments, as shown in the attached Figure 5-6As shown, the mounting seat 1022 is a raised clamping column or a recessed groove body, and the clamping arm 11 also includes a cover plate 114 arranged on the mounting groove 20, and a clamping platform 1141 is arranged on the cover plate 114, and the clamping platform 1141 has a semicircular opening. A support platform 115 with a semicircular opening is arranged on the clamping arm 11 opposite to the clamping platform 1141, and the support platform 115 is located in the mounting groove 20, and the mounting seat 1022 is used to fix one end of the spring 103. In this embodiment, the mounting seat 1022 is a raised clamping column, and one end of the spring 103 is sleeved on the mounting seat 1022. One end of the spring 103 extends to the support platform 115 and contacts with the inner wall of the mounting groove 20 to form an elastic abutment state. When the cover plate 114 is closed, the semicircular opening on the clamping platform 1141 and the semicircular opening on the support platform 115 form a closed circular bayonet, which limits and fixes the other end of the spring 103, thereby preventing the spring 103 from falling off.
[0034] In some embodiments, as shown in the attached Figure 8 As shown, the clamp arm 11 has a slide bar 111 of a certain length, and a raised slideway 112 is provided on one side of the slide bar 111. The slideway 112 extends from the end of the slide bar 111 to the outer wall corresponding to the mounting groove 20. The slideway 112 is provided with a tooth pattern 113. The slide bar 111 is used to adjust the width between the left and right clamp arms of the headrest and neck pillow.
[0035] In some embodiments, as shown in the attached Fig. 9 As shown, an extension bracket is rotatably connected to the extension arm 12, and the extension bracket is a fixing bracket for a mobile phone or a tablet computer, which is convenient for users to fix the mobile phone or tablet computer on the extension bracket while driving, so as to better watch videos and other operations.
