Description

Technical Field

[0001] The invention relates to the technical field of neck-hanging electronic product manufacturing, in particular to a neck connection structure of a neck-hanging electronic product. Background Art

[0002] Neck-hanging electronic products have attracted much attention in recent years, mainly including neck-hanging Bluetooth headsets, neck-hanging speakers, and neck-hanging smart sports equipment. The neck-hanging design can reduce the burden on the ears or head, and will not feel uncomfortable even if worn for a long time. It is comfortable to wear and stylish in appearance. With people's pursuit of portability and personalization, the market prospects of neck-hanging electronic products are broad. Continuous technological innovation has brought more surprises and convenience to users.

[0003] Neck-hanging electronic products are generally "U" shaped, and rubber parts are generally used on the outside of the neck where the left and right parts are connected. Rubber materials are usually soft and can provide better comfort when in contact with the neck. However, rubber parts are often not strong enough. Rubber with high hardness is prone to aging and brittleness, while rubber with lower hardness is not enough to support the weight of the structure connecting the left and right parts. Therefore, it is necessary to embed resin parts inside the rubber parts to increase the strength. However, embedding resin in rubber parts will greatly increase the mold cost, component cost and assembly cost. On the other hand, the surface of rubber parts easily absorbs dust, dirt and other impurities, making it relatively difficult to clean. Summary of the invention

[0004] In view of the above problems, the present invention provides a neck connection structure for a neck-hanging electronic product.

[0005] The technical means adopted by the present invention are as follows:

[0006] A neck connection structure for a neck-hanging electronic product, comprising: a neck bracket for cooperating with a user's neck;

[0008] Both ends of the neck support are provided with component connection structures for connecting with components on both sides.

[0009] Further, the component connection structure includes an arc-shaped mating surface located at the end of the neck bracket for mating with the end of the bottom cover of the component and a square mating surface located at the end of the neck bracket for mating with the end of the top cover of the component, and the arc-shaped mating surface is provided with one or more first transverse rib accommodating grooves for accommodating the first transverse rib in the bottom cover, and when the bottom cover is buckled on the arc-shaped mating surface, the first transverse rib in the bottom cover is inserted into the first transverse rib accommodating groove;

[0010] The square mating surface is provided with one or more second transverse rib receiving grooves for receiving the second transverse rib in the top cover, and when the top cover is buckled on the square mating surface, the second transverse rib in the top cover is inserted into the second transverse rib receiving groove;

[0011] The end of the neck support is also provided with a screw sleeve accommodating hole for accommodating the screw sleeves on the bottom cover and the top cover.

[0012] Furthermore, a top cover end edge accommodating groove for accommodating the end edge of the top cover is also provided on the end of the neck support.

[0013] Furthermore, a screw plug receiving groove for receiving the screw plug is also provided on the bottom cover.

[0014] Furthermore, a screw plug positioning hole for positioning the screw plug is provided in the screw plug receiving groove on the bottom cover.

[0015] Furthermore, the cross-sectional area of ​​the neck support gradually increases from the middle to both ends of the neck support.

[0016] Furthermore, the threading hole is a square hole.

[0017] Compared with the prior art, the neck connection structure of the neck-hanging electronic product disclosed in the present invention has the following beneficial effects: since it is made of thermoplastic elastomer (TPE) resin material with a Shore hardness of A60 to A80, and both ends of the neck bracket are provided with component connection structures for connecting with components on both sides, the neck bracket can not only meet the comfort requirements when the user's neck touches it, but also meet the strength requirements for supporting electronic components on both sides.

DETAILED DESCRIPTION

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the neck connection structure of the neck-hanging electronic product disclosed in the present invention comprises: a neck support 1 for matching with the neck of a user;

[0026] The neck bracket 1 is made of a thermoplastic elastomer resin material with a Shore hardness of A60 to A80, and a threading hole 10 is provided in the neck bracket 1;

[0027] Component connection structures 11 for connecting with components on both sides are provided at both ends of the neck support 1.

[0028] Specifically, in the present embodiment, the neck bracket adopts a thermoplastic elastomer (TPE) resin material with a Shore hardness of A60 to A80, and the neck bracket is approximately a "U"-shaped structure to facilitate cooperation with the user's neck. A threading hole is provided inside the neck bracket to facilitate insertion of a power cord and / or a control cord for powering or controlling the electronic components on both sides. The electronic components on both sides may be neck-hanging Bluetooth headsets, neck-hanging speakers, and neck-hanging smart sports equipment, etc., and component connection structures for connecting to the electronic components on both sides are provided at both ends of the neck bracket. In the present application, the neck bracket only adopts a thermoplastic elastomer (TPE) with a Shore hardness of A60 to A80. (TPE) resin material makes the neck bracket not only meet the comfort requirements of the user's neck when in contact with it, but also meet the strength requirements for supporting the electronic components on both sides. Moreover, since the neck bracket is made of only resin, compared with the existing neck bracket that conventionally uses rubber and embeds resin in the rubber, the mold opening cost of the neck bracket is greatly reduced, the number of components is reduced, and the product cost and assembly cost are saved. At the same time, the problem of electrostatic adsorption on the surface of rubber products that has always existed in the industry usually requires spraying hand oil to solve it. The use of TPE resin material not only completely solves the problem, but also avoids the cost increase caused by spraying hand oil.

[0029] Further, the component connection structure 11 includes an arcuate mating surface 110 located at the end of the neck support 1 for mating with the end of the bottom cover 2 of the component and a square mating surface 111 located at the end of the neck support 1 for mating with the top cover 3 of the component, and the arcuate mating surface 110 is provided with one or more first transverse rib accommodating grooves 112 for accommodating the first transverse rib in the bottom cover 2. When the bottom cover 2 is buckled on the arcuate mating surface 110, the first transverse rib in the bottom cover 2 is inserted into the first transverse rib accommodating groove 112;

[0030] The square mating surface 111 is provided with one or more second transverse rib receiving grooves 113 for receiving the second transverse rib 30 in the top cover 3. When the top cover 3 is buckled on the square mating surface 111, the second transverse rib 30 in the top cover 3 is inserted into the second transverse rib receiving grooves 113.

[0031] The end of the neck support 1 is also provided with a screw sleeve accommodating hole 114 for accommodating the screw sleeves on the bottom cover 2 and the top cover 3 .

[0032] Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, both ends of the neck bracket are also provided with component connection structures for connecting to the electronic components at both ends. One side of the end of the neck bracket is an arcuate surface, and the other side is a square surface. The arcuate surface forms an arcuate mating surface for mating with the bottom cover end of the component, and the square surface forms a square mating surface for mating with the top cover end of the component. The top cover and the bottom cover can be interlocked and connected to the end of the neck bracket. At the same time, one or more first transverse rib accommodating grooves and second transverse rib accommodating grooves are also provided on the arcuate mating surface and the square mating surface. One or more first transverse ribs and second transverse ribs are provided (the first transverse ribs are not shown in the figure, and the setting of the first transverse ribs is the same as that of the second transverse ribs). When the bottom cover and the top cover are interlocked and installed at the end of the neck bracket, the first transverse ribs and the second transverse ribs are respectively inserted into the first transverse rib accommodating groove and the second transverse rib accommodating groove (the transverse ribs refer to the reinforcing rib structure arranged along the width direction on the inner side of the bottom cover or the top cover), thereby realizing the lateral fixation of the bottom cover (top cover) and the neck bracket, avoiding the disengagement between the bottom cover (top cover) and the neck bracket, and ensuring the strength of the neck bracket. At the same time, the cross-sectional area of ​​the neck bracket gradually increases from the middle to the two ends, and the meat thickness increases accordingly. The end slots can effectively solve the problem of shrinkage caused by uneven meat thickness. A screw column sleeve accommodating hole is also provided on the neck bracket, and a screw column sleeve is provided on the bottom cover and the top cover. When the bottom cover and the top cover are interlocked and installed at the end of the neck bracket, the screw column sleeve can be inserted into the screw column sleeve accommodating hole and the bottom cover and the top cover are fastened together by screws. Since the neck bracket is made of thermoplastic elastomer (TPE) material, its hardness is lower than that of the resin material of the bottom cover and top cover. By setting screw sleeve accommodating holes on the neck bracket to wrap the screw sleeve structure of the bottom cover and top cover, the problem of low hardness of the neck bracket not being suitable for hard connection is effectively avoided. At the same time, the three are also closely matched together to meet the strength requirements for use.

[0033] Furthermore, a top cover end edge receiving groove 115 for receiving the top cover end edge 31 is also provided on the end of the neck support 1 .

[0034] Specifically, a top cover end edge accommodating groove is provided at the root of the square mating surface, and the end of the top cover is provided with an edge protruding toward the inner side of the top cover. When the top cover is buckled on the square mating surface, the edge of the top cover end is inserted into the top cover end edge accommodating groove on the neck bracket. This structure can further limit the top cover to prevent the top cover from detaching from the neck bracket.

[0035] Furthermore, a screw plug receiving groove 21 for receiving the screw plug 5 is also provided on the bottom cover 2 .

[0036] Specifically, Figure 4 , Figure 5 and Figure 6As shown, screw sleeves are provided on the inner sides of the bottom cover and the top cover. In this embodiment, one end of the second screw sleeve 32 on the top cover connected to the main body of the top cover is a blind end, and the other end is provided with a threaded hole; the first screw sleeve 23 on the bottom cover is provided with a screw through hole, and the screw sleeve receiving hole 114 is a stepped hole. The outer diameter of the first screw sleeve is larger than the outer diameter of the second screw sleeve. The screw can be inserted into the screw sleeve of the bottom cover from the outside of the bottom cover and connected to the screw sleeve on the top cover to achieve the screw connection between the top cover and the bottom cover. At the same time, a screw plug receiving groove for accommodating a screw plug is provided on the bottom cover. After the top cover and the bottom cover are tightened and connected by screws, a screw plug can be inserted into the screw plug receiving groove to avoid the exposure of the screw and ensure the beauty of the product. In this embodiment, two screw plugs 50 are provided on the screw plug, and the screw plugs can be inserted into the screw through holes of the bottom cover to ensure the tight connection between the screw plug and the bottom cover and avoid the separation between the two.

[0037] Furthermore, a screw plug positioning hole 22 for positioning the screw plug 5 is provided in the screw plug receiving groove 21 on the bottom cover 2 .

[0038] Specifically, a positioning column is also provided on the screw plug, and the positioning column is arranged on a protruding structure on the screw plug. The distances between the positioning column and the two screw plug columns are different. A through hole is also provided in the screw plug accommodating groove of the bottom cover to form a screw plug positioning hole. When the screw plug is buckled in the screw plug accommodating groove, the positioning column can be conveniently inserted into the screw plug positioning hole first. Since the distances between the positioning column and the two screw plug columns are different, the screw plug can be conveniently positioned to ensure that the screw plug is installed correctly.

[0039] Furthermore, the cross-sectional area of ​​the neck support 1 gradually increases from the middle to both ends of the neck support 1 .

[0040] Specifically, the cross-sectional area of ​​the neck support gradually increases from the middle to both ends, which can ensure both its strength and its comfort when in contact with the user, while also ensuring the beauty of the product.

[0041] Furthermore, the threading hole 10 is a square hole.

[0042] Specifically, Figure 4 As shown, the threading hole in the neck bracket is a square hole with the following advantages: First, from the perspective of operability, since the tip structure of the wire socket is square, the square has a larger cross-section than the round one, and the operability is better. Secondly, compared with other special shapes, the square hole core mold is easier to process. Thirdly, since the neck bracket is an arc structure, the mold requires the cores on both sides to slide in and collide out of the mold. When the square hole collides in the middle of the arc of the neck bracket, it is not easy to misalign and produce flash, which can ensure the quality of the parts and ensure the smoothness of subsequent threading operations.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
