[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0030] This utility model embodiment provides a neck brace, such as Figures 1 to 4 As shown, the neck support includes a mounting base 10, a fixing mechanism 20, a neck support 30, and a flexible buffer structure 40.
[0031] The mounting base 10 includes a main body 11 and a mounting plate 12. The back of the main body 11 is provided with a mounting groove 11a, and the mounting plate 12 is installed in the mounting groove 11a.
[0032] The fixing mechanism 20 is installed on the front of the main body 11 and is used to connect the shooting device. The shooting device can be a mobile phone, action camera, or other device with shooting function. The fixing mechanism 20 can adopt a conventional structure for connecting and fixing shooting devices, and there are no specific restrictions here.
[0033] The two ends of the neck hanger 30 are connected to the main body 11 respectively.
[0034] The flexible buffer structure 40 includes a mounting portion 41 and a buffer portion 42 fixedly connected to the mounting portion 41. A buffer space is formed between the inner wall of the buffer portion 42 and the mounting plate 12. The mounting portion 41 includes an extension wall 412 and a limiting flange 411. The extension wall 412 is disposed between the buffer portion 42 and the limiting flange 411, and the extension wall 412 is arranged circumferentially along the buffer portion 42. The limiting flange 411 is arranged circumferentially along the extension wall 412 and extends to the center of the buffer portion 42 to a predetermined length. The extension wall 412 surrounds the outer periphery of the mounting plate 12 and clamps it between the mounting plate 12 and the side wall of the mounting groove 11a. The limiting flange 411 is clamped between the mounting plate 12 and the bottom wall of the mounting groove 11a. A buffer space is formed between the inner wall of the buffer portion 42 and the back of the mounting base 10. When the flexible buffer structure 40 is subjected to impact force, the buffer portion 42 deforms in the buffer space, absorbing and mitigating the impact force and improving the user's wearing comfort.
[0035] The neck support in this embodiment of the application can fix the shooting device on the front of the main body 11 of the mounting base 10 by installing the fixing mechanism 20 on the front of the main body 11 of the mounting base 10. The two ends of the neck hanger 30 are connected to the main body 11, so that the mounting base 10 together with the fixing mechanism 20 can be suspended at the user's neck. The flexible buffer structure 40 is assembled to the main body 11 by its mounting part 41 in conjunction with the mounting plate 12. The mounting part 41 is provided with an extension wall 412 arranged circumferentially along the buffer part 42 and a limiting protrusion 411 arranged circumferentially along the extension wall 412 and extending to the middle of the buffer part 42 to a preset length. The flexible buffer structure 40 is assembled to the main body. After step 11, the extension wall 412 is clamped between the side wall of the mounting groove 11a of the main body 11 and the outer periphery of the mounting plate 12, and the limiting protrusion 411 is clamped between the bottom wall of the mounting groove 11a of the main body 11 and the mounting plate 12. Therefore, after the flexible buffer structure 40 is assembled to the mounting base 10 through the mounting plate 12, the main body 11 and the mounting plate 12 can constrain the flexible buffer structure 40 from multiple directions, which greatly enhances the connection between the flexible buffer structure 40 and the mounting plate 12 and the main body 11, reduces the risk of the flexible buffer structure 40 falling off due to continuous high-frequency vibration or accidental impact, maintains the buffering effect, and improves the user experience.
[0036] In an optional embodiment of this application, reference is made to Figure 4 The mounting part 41 and the buffer part 42 are integrally formed. This eliminates the possibility of loosening between the mounting part 41 and the buffer part 42, strengthens the overall structural strength of the flexible buffer structure 40, and improves its reliability. In terms of assembly, the flexible buffer structure 40 can be formed in one step through injection molding, compression molding, and other processes, reducing the assembly steps of the neck bracket, lowering production complexity and labor costs, reducing the number of parts, simplifying supply chain management and quality control, and making mass production easier.
[0037] Optionally, the flexible buffer structure 40 may be made of flexible materials such as silicone or rubber.
[0038] In an optional embodiment of this application, reference is made to Figure 2 , Figure 4 and Figure 6 A first limiting structure 4111 is provided on the limiting protrusion 411, and a second limiting structure 111 is provided on the bottom wall of the mounting groove 11a. The second limiting structure 111 cooperates with the first limiting structure 4111 to further restrict the limiting protrusion 411 from detaching from the main body 11 along the buffer part 42 radially.
[0039] The bottom wall of the mounting groove 11a and the limiting protrusion 411 are further restricted from detaching from the main body 11 radially along the buffer portion 42 by the cooperation of the first limiting structure 4111 and the second limiting structure 111. When subjected to greater impact force, or when the material of the flexible buffer structure 40 ages or fatigues and loses elasticity, the cooperation of the first limiting structure 4111 and the second limiting structure 111 can restrict the limiting protrusion 411 from detaching from the main body 11 radially along the buffer portion 42, preventing the flexible buffer structure 40 from falling off the main body 11 as a whole, and ensuring that the neck bracket can still maintain complete assembly under long-term use or accidental stress. In addition, the cooperation between the first limiting structure 4111 and the second limiting structure 111 can also provide an auxiliary positioning reference for the assembly of the flexible buffer structure 40. During assembly, the cooperation between the first limiting structure 4111 and the second limiting structure 111 can help the main body 11 of the flexible buffer structure 40 to be assembled in place, while reducing the reliance on the skills of the operator during assembly, and eliminating the need to repeatedly adjust the position to ensure that the clamping is in place.
[0040] In an optional embodiment of this application, reference is made to Figure 2 , Figure 4 and Figure 6 The first limiting structure 4111 includes a first limiting groove 411a arranged circumferentially along the limiting protrusion 411, and the second limiting structure 111 includes a first limiting protrusion 1111 provided on the bottom wall of the mounting groove 11a. The first limiting protrusion 1111 is adapted to be received in the first limiting groove 411a.
[0041] Specifically, the first limiting protrusion 1111 on the main body 11 is adapted to be received in the first limiting groove 411a on the limiting protrusion 411. In this way, the limiting protrusion 411 can be restricted from sliding outward in the radial direction of the buffer part 42, preventing the flexible buffer structure 40 from detaching from the main body 11 axially under the action of external force, thereby further preventing the flexible buffer structure 40 from detaching from the mounting base 10 axially along the buffer part 42. In terms of assembly, it also facilitates the assembly and alignment between the main body 11 and the flexible buffer structure 40.
[0042] In an optional embodiment of this application, reference is made to Figure 4 and Figure 5 The limiting protrusion 411 is provided with a first notch 411b and a second notch 411c. The first notch 411b and the second notch 411c are symmetrically arranged and both extend from the inner peripheral surface of the limiting protrusion 411 to the outer peripheral surface of the limiting protrusion 411.
[0043] By providing a first notch 411b and a second notch 411c on the limiting flange 411, a stronger elastic adjustment space is provided for the limiting flange 411, greatly simplifying the assembly process with the mounting plate 12. Specifically, both the first notch 411b and the second notch 411c extend from the inner circumferential surface of the limiting flange 411 to the outer circumferential surface of the limiting flange 411, allowing the limiting flange 411 to open and close flexibly. During assembly, the operator only needs to gently pry the limiting flange 411 portions on both sides of the first notch 411b and the second notch 411c to quickly expand the inner circumferential diameter of the limiting flange 411, easily fitting the flexible buffer structure 40 onto the outer circumference of the mounting plate 12 without forced compression or the need for tool assistance.
[0044] In an optional embodiment of this application, reference is made to Figure 2 , Figure 4 and Figure 5 A limiting arm 121 is provided on the side of the mounting plate 12 facing the main body 11. When the limiting protrusion 411 is clamped between the mounting plate 12 and the bottom wall of the mounting groove 11a, the inner circumferential surface of the limiting protrusion 411 abuts against the limiting arm 121. With this configuration, the limiting arm 121 provides a radial positioning reference for the limiting protrusion 411. During assembly, the flexible buffer structure 40 is sleeved on the outer circumference of the mounting plate 12 until the inner circumferential surface of the limiting protrusion 411 abuts against the limiting arm 121, indicating that the limiting protrusion 411 has been assembled in place. This avoids excessive pulling of the mounting part 41 and the buffer part 42, and avoids the deviation of the limiting protrusion 411 due to human operation deviation. This ensures that when the mounting plate 12 and the main body 11 are subsequently fitted together, the size of the buffer space and the clamping force of the protrusion meet the design standards, and the buffering performance is stable.
[0045] In an optional embodiment of this application, reference is made to Figure 4 and Figure 5 A third limiting structure 4112 is provided on the limiting protrusion 411, and a fourth limiting structure 122 is provided on the side of the mounting plate 12 facing the main body 11. The fourth limiting structure 122 cooperates with the third limiting structure 4112 to further restrict the limiting protrusion 411 from detaching from the mounting plate 12 radially along the buffer part 42.
[0046] The limiting protrusion 411 is further restricted from detaching from the mounting plate 12 radially along the buffer portion 42 by the cooperation of the third limiting structure 4112 and the fourth limiting structure 122. Specifically, when subjected to a greater impact force, or when the material of the flexible buffer structure 40 ages or fatigues and experiences elastic decay, the cooperation of the third limiting structure 4112 and the fourth limiting structure 122 can firmly fix the limiting protrusion 411 to the mounting plate 12, preventing the limiting protrusion 411 from detaching from the mounting plate 12 radially along the buffer portion 42, and thus preventing the flexible buffer structure 40 from detaching from the mounting base 10. In addition, the cooperation of the third limiting structure 4112 and the fourth limiting structure 122 can also provide an auxiliary positioning reference for the assembly of the flexible buffer structure 40. During assembly, the cooperation of the third limiting structure 4112 and the fourth limiting structure 122 can assist in the proper assembly of the flexible buffer structure 40 and the mounting plate 12, while reducing the reliance on the operator's skills during assembly, eliminating the need for repeated adjustments to ensure proper clamping.
[0047] In an optional embodiment of this application, reference is made to Figure 4 and Figure 5 The third limiting structure 4112 includes a plurality of second limiting slots 411d provided on the limiting protrusion 411, the plurality of second limiting slots 411d being distributed at intervals along the circumference of the mounting plate 12. The fourth limiting structure 122 includes a plurality of second limiting protrusions 1221 provided on the mounting plate 12 facing the main body 11, the plurality of second limiting protrusions 1221 being provided in a one-to-one correspondence with the plurality of second limiting slots 411d, and the second limiting protrusions 1221 being adapted to be received in the second limiting slots 411d.
[0048] Specifically, the second limiting slot 411d and the second limiting protrusion 1221 correspond one-to-one and are spaced apart circumferentially, realizing circumferential anti-rotation positioning of the limiting protrusion 411 and the mounting plate 12, and limiting the radial separation of the limiting protrusion 411 from the mounting plate 12 along the buffer part 42. During assembly, the second limiting protrusion 1221 of the mounting plate 12 precisely engages with the second limiting slot 411d of the limiting protrusion 411. This design can directly limit the relative rotation of the two in the circumferential direction and the relative movement in the radial direction. Multiple second limiting slots 411d and second limiting protrusions 1221 can also add multiple auxiliary fixing points in the circumferential direction, making the connection between the flexible buffer structure 40 and the mounting base 10 tighter. In terms of assembly, the second limiting slot and the second limiting protrusion 1221 provide a visual alignment reference during the assembly process of the limiting protrusion 411 and the mounting plate 12, reducing the difficulty of operation and ensuring the consistency of mass production. During assembly, operators can quickly position the device by intuitively aligning the second limiting protrusion 1221 with the second limiting slot 411d, eliminating the need for repeated adjustments to the circumferential angle between the limiting protrusion 411 and the mounting plate 12, thus significantly reducing assembly time. Furthermore, the one-to-one correspondence between the second limiting slot 411d and the second limiting protrusion 1221 ensures consistent fit between the flexible buffer structure 40 and the mounting plate 12, preventing issues such as circumferential loosening or excessive tightness of the flexible buffer structure 40 due to manual alignment deviations, thereby improving overall production quality.
[0049] In an optional embodiment of this application, reference is made to Figure 3 , Figure 5 and Figure 6 The mounting plate 12 and the bottom wall of the mounting groove 11a are provided with a plurality of buckles 123 on one side and a plurality of holes 11b corresponding to the buckles 123 on the other side. The buckles 123 are engaged in the holes 11b.
[0050] The main body 11 and the mounting plate 12 can be quickly assembled using the snap-fit 123 and the locking hole 11b, significantly reducing the complexity of the assembly operation. During assembly, the operator only needs to align the snap-fit 123 of the mounting plate 12 with the locking hole 11b of the main body 11 and gently press or push to complete the assembly and fixation of the main body 11 and the mounting plate 12 without the need for additional tools, thus improving production efficiency. In addition, the snap-fit 123 and the locking hole 11b can achieve a reliable mechanical lock, reducing the possibility of loosening between the main body 11 and the mounting plate 12 during use. When it is necessary to replace the flexible buffer structure 40, the main body 11 and the mounting plate 12 can also be separated, which is very convenient. Through the cooperation of multiple snap-fit 123 and the corresponding locking hole 11b, a multi-point distributed mechanical lock is formed to ensure the stability of the connection between the main body 11 and the mounting plate 12. When the buckle 123 is engaged in the buckle hole 11b, the barb structure of the buckle 123 will form an independent reverse constraint with the mounting plate 12. Multiple sets of engagement can jointly resist axial separation force and radial shear force from different positions, preventing the main body 11 from separating from the mounting plate 12 as a whole, and achieving stable clamping of the limiting protrusion 411 of the flexible buffer structure 40.
[0051] The latch 123 can be disposed on the main body 11, and the corresponding latch hole 11b can be disposed on the mounting plate 12; or, the latch 123 can be disposed on the mounting plate 12, and the corresponding latch hole 11b can be disposed on the main body 11. For example, the latch 123 is disposed on the mounting plate 12, and the corresponding latch hole 11b is disposed on the main body 11.
[0052] In an optional embodiment of this application, reference is made to Figure 3 , Figure 5 and Figure 6 The mounting plate 12 and the mounting groove 11a are provided with a plurality of through holes 12a on the bottom wall of the buckle 123. The through holes 12a correspond one-to-one with the buckle 123 and are located on the side of the corresponding buckle 123.
[0053] The buckle 123 is a typical undercut structure. By setting a through hole 12a on the side of the buckle 123, when injection molding the mounting plate 12 or main body 11 with the buckle 123, the through hole 12a can be used to break the limitation of the undercut structure on the mold, without the need to add an additional inclined ejector, simplifying the mold design and processing flow, and reducing the mold manufacturing cost and subsequent maintenance cost.
[0054] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
