[0036] In the description of the present invention, "plurality" means two or more.

[0037] The following describes a cervical massage apparatus 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0038] like Figure 1-Figure 2 As shown, the cervical massager 1 includes an elastic support 100 , a left clamping arm 200 , a right clamping arm 300 and a middle support 400 .

[0039] The elastic bracket 100 is arc-shaped, and includes an elastic portion 110, a left non-elastic portion 120, and a right non-elastic portion 130. The left non-elastic portion 120 is arranged at the left end of the elastic portion 110, and the right non-elastic portion 130 is arranged at the right end of the elastic portion 110. Both sides of the left non-elastic portion 120 in the width direction are bent toward the right non-elastic portion 130 so that the cross section of the left non-elastic portion 120 is arc-shaped, and both sides of the right non-elastic portion 130 in the width direction are bent toward the left non-elastic portion 120 so that the cross section of the right non-elastic portion 130 is arc-shaped. The left clamp arm 200 is installed on the left non-elastic portion 120, and the right clamp arm 300 is installed on the right non-elastic portion 130. The intermediate bracket 400 is installed on the elastic portion 110, and the left end of the intermediate bracket 400 is connected to the left clamp arm 200 and the right end of the intermediate bracket 400 is connected to the right clamp arm 300.

[0040] For example, the elastic part 110 is C-shaped, and the middle bracket 400 is installed on the side of the elastic part 110 facing the human neck. The curvature of the left non-elastic part 120 gradually increases in the direction away from the elastic part 110, and the curvature of the right non-elastic part 130 gradually increases in the direction away from the elastic part 110, and the middle bracket 400 can be made of a flexible material, such as non-conductive silicone, so that the middle bracket 400 can deform with the user's neck and find a shape and state suitable for the user's neck, so that it can effectively fit the user's neck skin, thereby improving wearing comfort.

[0041] According to the cervical massager 1 of the embodiment of the present invention, by bending both sides of the left non-elastic part 120 in the width direction toward the right non-elastic part 130 so that the cross-section of the left non-elastic part 120 is arc-shaped, and bending both sides of the right non-elastic part 130 in the width direction toward the left non-elastic part 120 so that the cross-section of the right non-elastic part 130 is arc-shaped, the rigidity of the left non-elastic part 120 and the right non-elastic part 130 can be increased. When the cervical massager 1 is pulled, the left non-elastic part 120 and the right non-elastic part 130 will basically not be deformed, and the non-elastic part and the clamping arm will not be separated, thereby ensuring the stability of the relative position between the left non-elastic part 120 and the left clamping arm 200 and the stability of the relative position between the right non-elastic part 130 and the right clamping arm 300, thereby increasing the service life of the cervical massager 1.

[0042] In this way, the cervical massager 1 according to the embodiment of the present invention increases the rigidity of the connection between the elastic bracket 100 and the clamping arm, and has the advantages of stable structure, long service life, etc.

[0043] According to some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the width of the bent portion of the left non-elastic portion 120 gradually decreases toward the elastic portion 110, and the width of the bent portion of the right non-elastic portion 130 gradually decreases toward the elastic portion 110. In this way, the width of the bent portion at the end of the left non-elastic portion 120 and the right non-elastic portion 130 is relatively large, which can provide guidance and force application points when the user wears it, making it easier for the user to wear it, and it is more in line with the shape of the human neck, thereby improving the wearing comfort. In addition, the width of the bent portion at the end of the left non-elastic portion 120 and the right non-elastic portion 130 is relatively large, which is also convenient for the user to hold, and is not easy to fall off, thereby reducing the damage to the cervical massager 1 caused by falling off.

[0044] Furthermore, if Figure 2As shown, the left non-elastic portion 120 is bent toward the right non-elastic portion 130 to form a left installation space 210, and the cross-sectional area of ​​the left installation space 210 gradually increases in the direction away from the elastic portion 110. The right non-elastic portion 130 is bent toward the left non-elastic portion 120 to form a right installation space 310, and the cross-sectional area of ​​the right installation space 310 gradually increases in the direction away from the elastic portion 110. In this way, the arrangement of the left installation space 210 and the right installation space 310 can enable the cervical massager 1 to accommodate more electronic components.

[0045] Furthermore, if Figure 2 As shown, the left clamp arm 200 covers the left installation space 210, and the right clamp arm 300 covers the right installation space 310, which prevents electronic components from falling off from the installation space, improves the reliability of the cervical massager 1, and increases the overall smoothness of the surface of the cervical massager 1, thereby increasing the wearing comfort. In addition, it also reduces the probability of dust entering the left installation space 210 and the right installation space 310, thereby increasing the cleanliness of the cervical massager 1.

[0046] According to some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, a left step 220 is formed between the end surface of the left clamp arm 200 and the end surface of the left non-elastic portion 120 , and a right step 320 is formed between the end surface of the right clamp arm 300 and the end surface of the right non-elastic portion 130 .

[0047] Specifically, the end surface of the left clamp arm 200 away from the middle bracket 400 protrudes from the left end surface of the elastic bracket 100, and the end surface of the right clamp arm 300 away from the middle bracket 400 protrudes from the right end surface of the elastic bracket 100. In this way, when the end of the cervical massager 1 is hit (such as falling), the left clamp arm 200 or the right clamp arm 300 is hit before the elastic bracket 500, thereby preventing the cervical massager 1 from being separated when the end is hit.

[0048] According to some specific embodiments of the present invention, Figure 1 As shown, a button 140 is provided on an outer surface of at least one of the left non-elastic portion 120 and the right non-elastic portion 130 .

[0049] For example, the button 140 is arranged on the outer surface of the left non-elastic part 120 and / or the right non-elastic part 130 except the side close to the human neck. This is convenient for user operation and does not affect the smoothness of the surface of the left non-elastic part 120 and the right non-elastic part 130.

[0050] According to some specific embodiments of the present invention, Figure 1As shown, the left non-elastic part 120 is symmetrically arranged about the central plane that bisects the elastic support 100 in the width direction of the elastic support 100, and the right non-elastic part 130 is symmetrically arranged about the central plane that bisects the elastic support 100 in the width direction of the elastic support 100. In this way, the elastic support 100 has a reasonable structure and a smooth surface, which improves the wearing comfort.

[0051] According to some specific embodiments of the present invention, Figure 1 As shown, the edges of the elastic part 110, the left non-elastic part 120 and the right non-elastic part 130 on the same side in the width direction are located in the same plane. In this way, when the cervical massager 1 is placed on a horizontal surface (e.g., a desktop), the cervical massager 1 can remain horizontal, and the overall force is evenly applied, thereby preventing the cervical massager 1 from shaking.

[0052] According to some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the cervical massager 1 further includes a left cover plate 230 and a right cover plate 240. The left clamp arm 200 is mounted on the left non-elastic part 120 via a left threaded fastener, and the left cover plate 230 is mounted on the left clamp arm 200 and covers the left threaded fastener. The right clamp arm 300 is mounted on the right non-elastic part 130 via a right threaded fastener, and the right cover plate 240 is mounted on the right clamp arm 300 and covers the right threaded fastener.

[0053] Specifically, the left step 220 is formed by the left cover plate 230 and the left non-elastic part 120, and the right step 320 is formed by the right cover plate 330 and the right non-elastic part 130. The end surface of the left cover plate 230 away from the middle bracket 400 protrudes from the end surface of the left non-elastic part 120, and the end surface of the right cover plate 330 away from the middle bracket 400 protrudes from the end surface of the right non-elastic part 130. In this way, when the end of the cervical massager 1 is hit (such as falling), the left cover 230 or the right cover 330 is impacted before the elastic bracket 100, and the buckle of the left cover 230 connected to the left non-elastic part 120 is bent toward the left clamping arm 200, and the buckle of the right cover 330 connected to the right non-elastic part 130 is bent toward the right clamping arm 300. Therefore, when the left cover 220 is impacted, the connection strength with the left clamping arm 200 is increased, and when the right cover 330 is impacted, the connection strength with the right clamping arm 300 is increased, thereby avoiding structural detachment of the cervical massager 1 when it is hit, and increasing the overall structural stability of the cervical massager 1.

[0054] In addition, the left cover plate 230 covers the left threaded fastener and the right cover plate 240 covers the right threaded fastener, which not only prevents the fasteners from being directly exposed to the air, but also reduces the speed at which the fasteners rust and corrode, thereby increasing the service life of the cervical massager 1.

[0055] Furthermore, if Figure 2As shown, the distance between the left cover plate 230 and one end of the left non-elastic portion 120 adjacent to the elastic portion 110 in the length direction of the elastic bracket 100 is 4 / 6 to 5 / 6 of the length of the left non-elastic portion 120, and the distance between the right cover plate 240 and one end of the right non-elastic portion 130 adjacent to the elastic portion 110 in the length direction of the elastic bracket 100 is 4 / 6 to 5 / 6 of the length of the right non-elastic portion 130.

[0056] Furthermore, if Figure 2 As shown, the distance between the left cover plate 230 and one end of the left non-elastic portion 120 adjacent to the elastic portion 110 in the length direction of the elastic bracket 100 is 5 / 7 of the length of the left non-elastic portion 120, and the distance between the right cover plate 240 and one end of the right non-elastic portion 130 adjacent to the elastic portion 110 in the length direction of the elastic bracket 100 is 5 / 7 of the length of the right non-elastic portion 130.

[0057] Thus, on the one hand, it can ensure that the non-elastic part can reserve enough space for installing the cover plate, thereby improving the connection stability between the non-elastic part and the cover plate; on the other hand, it can ensure that there is an appropriate distance between the left non-elastic part 120 and the right non-elastic part 130, thereby avoiding the user's sense of oppression during use and improving the wearing experience. In addition, installation space can also be reserved for electronic devices in the cervical massager 1.

[0058] In addition, when the distance between the cover plate and one end of the non-elastic part adjacent to the elastic part 110 in the length direction of the elastic bracket 100 is 5 / 7 of the length of the non-elastic part, the connection strength and wearing effect of the left and right non-elastic parts and the cover plate are most comfortable.

[0059] According to some specific embodiments of the present invention, Figure 3 As shown, the maximum center angle of the cross section of the left non-elastic part 120 is greater than 90°, and the maximum center angle of the cross section of the right non-elastic part 130 is greater than 90°. This further ensures the rigidity of the non-elastic part, prevents displacement between the elastic part and the clamping arm, and improves the structural stability of the cervical massager 1.

[0060] According to some specific embodiments of the present invention, Figure 4 As shown, the cross section of the elastic part 110 is an arc convex away from the human neck, and the distance of the center of the elastic part 110 in the width direction relative to the two sides is less than 2mm. In this way, the outer surface of the elastic part 110 is approximately flat, which can make the elastic part 110 have good elasticity, and then make the cervical massager 1 maintain good restoring force, so that the cervical massager 1 can fit the skin of the human neck better and improve the massage comfort.

[0061] According to some specific embodiments of the present invention, Figure 2As shown, the elastic part 110, the left non-elastic part 120 and the right non-elastic part 130 are integrally formed. This simplifies the production process, reduces the production steps, improves the production efficiency, and increases the connection strength between the elastic part 110, the left non-elastic part 120 and the right non-elastic part 130, thereby improving the structural stability of the cervical massager 1.

[0062] According to some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the cervical massager 1 also includes a conductive belt 500 , which is installed on the middle bracket 400 .

[0063] The conductive belt 500 is made of a flexible material, such as conductive silicone, and is almost flush with the side of the middle bracket 400 facing the human neck. The conductive belt 500 can be deformed along with the middle bracket 400, so that it can better fit the user's neck skin, thereby improving the user's wearing comfort. In addition, the middle bracket 400 and the conductive belt 500 made of silicone are soft in texture, and the foreign body sensation in contact with the user's neck is light, and the comfort is good.

[0064] In addition, the conductive belt 500 can be a plurality of strip-shaped conductive belts arranged at intervals along the length direction of the intermediate bracket 400, and the plurality of strip-shaped conductive belts include at least one positive strip-shaped conductive belt and at least one negative strip-shaped conductive belt. The strip-shaped conductive belt is used to replace the massage head electrode in the related art. The strip-shaped conductive belt does not need to protrude a large distance like the massage head electrode to provide the massage head adjustment space, thereby reducing the volume of the cervical massager 1. Moreover, through the arrangement of the plurality of strip-shaped conductive belts, when the cervical massager 1 is working, the plurality of strip-shaped conductive belts can form a loop with the human body to achieve the massage effect, and because the conductive belt 500 is arranged in a strip shape, and each conductive belt 500 extends along the length direction of the intermediate bracket 400, the total area of ​​contact between the plurality of conductive belts 500 and the human body is large, and compared with the local massage in the related art, a large continuous area massage is achieved, which not only increases the massage area, clears the massage blind spot, improves the user comfort, but also effectively avoids the occurrence of tingling, and ensures the comfort of the massage.
