Detailed ways

The embodiments of the present disclosure are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present disclosure are described in detail below.

As shown in FIGS. 1 to 3, in the embodiment of the present disclosure, the neck massager 10 includes a bracket 12, a battery 14, a control board 16 and a massage head 18.

The bracket 12 is used to support various components. The bracket 12 includes an elastic arm 200 and two clamping arm structures 300. The two clamping arm structures 300 are respectively arranged at two ends of the elastic arm 200, and the two clamping arm structures 300 are arranged opposite to each other and located on the same side of the elastic arm 200. In this way, when the neck massager 10 is used, the elasticity of the elastic arm 200 itself can be used to open the angle and restore the original shape, so that the massager 10 is suitable for necks of different sizes.

The battery 14 is disposed in one of the two clamping arm structures 300, and the control main board 16 is disposed in the other of the two clamping arm structures 300. The massage head 18 is arranged on the elastic arm 200. The battery 14 is used to supply power to the components of the neck massager 10 that need to be powered, for example, to power the control main board 16 and the massage head 18. The control main board 16 is in communication connection with the massage head 18 and is used to control the operation of the massage head 18. When the neck massager 10 is a low-frequency micro-current massager, the control main board 16 controls the massage head 18 to generate low-frequency microcurrent; when the neck massager 10 is a vibrating massager, the control main board 16 controls the massage head 18 to vibrate. Microcurrent, vibration, etc. act on the neck, which can have a positive effect on the neck. The battery 14 and the control main board 16 are respectively arranged in the two clamping arm structures 300, which can make the weight distribution of the entire neck massager 10 more balanced. The massage head 18 is used to massage the neck. The massage head 18 can directly contact the neck, and cooperate with the two clamping arm structures 300 to clamp the neck.

In this embodiment, the structures of the two clamping arm structures 300 are substantially the same, and only the space used for assembling the battery 14 and the corresponding battery fixings are different from the space used for the control main board 16 and the corresponding main board fixings. The following mainly introduces the common points of the two clamping arm structures 300.

As shown in FIGS. 1 to 3, the clamping arm structure 300 includes a housing 310 and an elastic protrusion 320.

The housing 310 includes an inner side surface 310a and an outer side surface 310b, and the inner side surface 310a is closer to the clamped object than the outer side surface 310b. In this embodiment, the arm clamping structure 300 is applied to the neck massager 10, and the clamped object is the neck. In other embodiments, when the arm clamping structure 300 is used in a waist massager, the object to be clamped is the waist; when the arm clamping structure 300 is used in a leg massager, the object to be clamped is the leg. In addition, it should be noted that the inner surface 310a and the outer surface 310b may be flat or any non-planar surfaces such as curved surfaces. The distinction between the inner and outer surfaces of the inner surface 310a and the outer surface 310b is mainly based on the clamped object.

The elastic protrusion 320 is protruded on the inner surface 310a. When the clamped object squeezes the elastic protrusion 320, the elastic protrusion 320 is deformed by force, and the elastic protrusion 320 alone or together with the inner surface 310 a located on the outer periphery of the elastic protrusion 320 abuts against the clamped object.

When wearing the above-mentioned clip arm structure 300, the elastic protrusion 320 provides additional elastic clinging force, which can make the wearing stronger. Moreover, the elastic protrusion is deformed by force and closely adheres to the clamped object, which is soft and close to the skin, and can bring a more comfortable feeling to the wearer.

In particular, when the elastic protrusion 320 and the inner side surface 310a located on the outer periphery of the elastic protrusion 320 together closely adhere to the clamped object, the inner side surface 310a can also provide close contact force, which can make the wearing stronger.

In this embodiment, the elastic protrusion 320 has a cavity 320 a, and the cavity 320 a facilitates the deformation of the elastic protrusion 320 and reduces the weight of the clamping arm structure 300. In other embodiments, the elastic protrusion 320 may also be a solid body.

In this embodiment, the elastic protrusion 320 is located in the middle of the inner surface 310a. When the elastic protrusion 320 is deformed by force and is in close contact with the clamped object, the outer periphery of the elastic protrusion 320 deformed by the force has a circle of inner surface. 310a, that is, the inner surface 310a of the outer periphery of the elastic protrusion 320 that is deformed by force is ring-shaped. This setting is more conducive to stabilizing the neck. It should be noted that the middle part mentioned here is not the middle part in the strict sense, but only needs to satisfy "the inner surface 310a of the outer periphery of the elastic protrusion 320 that is deformed by force is ring-shaped".

In other embodiments, the elastic protrusion 320 may also be located at the edge of the inner surface 310a. At this time, when the elastic protrusion 320 is deformed by force and is in close contact with the clamped object, the elastic protrusion 320 is deformed by force. The inner surface 310a of the outer periphery has a notch and is not annular.

In this embodiment, the housing 310 has a hollow structure. A mounting hole 3122 is opened on the inner side surface 310a, and the mounting hole 3122 is in communication with the hollow cavity 310c of the housing 310. The elastic protrusion 320 is inserted into the mounting hole 3122 on the side away from the clamped object. In this way, when the elastic protrusion 320 is deformed toward the outer surface 310b under a force, the mounting hole 3122 can receive a part of the elastic protrusion 320, and provide the elastic protrusion 320 with deformation capacity, which is more conducive to firm wearing. More importantly, the mounting hole 3122 The surrounding wall of the hole can play the role of supporting the elastic protrusion 320, assisting in enhancing the support strength of the elastic protrusion 320, and avoiding the elastic protrusion 320 from being excessively dented during use. In other embodiments, the mounting hole 3122 may be omitted. In this case, the elastic protrusion 320 may be directly provided on the inner surface 310a by means of glue bonding or the like.

Specifically, in this embodiment, the housing 310 includes an inner shell 312 and an outer shell 314 that are detachably connected. In this way, it is very convenient to assemble the elastic protrusion 320 and disassemble the components inside the housing 310. The inner shell 312 and the outer shell 314 are arranged along the direction from the inner side 310a to the outer side 310b, the inner side 310a is the side of the inner shell 312 away from the outer shell 314, and the outer side 310b is the side of the outer shell 314 away from the inner shell 312.

In this embodiment, the elastic protrusion 320 penetrates through the mounting hole 3122, and a part of the elastic protrusion 320 extends into the hollow cavity 310c. The elastic protrusion 320 is attached to the wall of the mounting hole 3122 in a natural state, and is partially separated in a squeezed state. The part of the elastic protrusion 320 extending into the hollow cavity 310c is connected to the housing 310. Specifically, in this embodiment, the mounting hole 3122 is opened in the inner shell 312, and the part of the elastic protrusion 320 extending into the hollow cavity 310c is connected to the inner shell 312. In other embodiments, the part of the elastic protrusion 320 extending into the hollow cavity 310 c may also be connected to the housing 314.

The elastic protrusion 320 is attached to the wall of the mounting hole 3122 in a natural state, and is partially separated in the squeezed state, that is, the elastic protrusion 320 is a movable part relative to the wall of the mounting hole 3122, and the elastic protrusion 320 is There is no glue between the wall of the mounting hole 3122, and the elastic protrusion 320 and the wall of the mounting hole 3122 are non-rigidly connected. In this way, the elastic protrusion 320 will not become loose due to degumming after being squeezed multiple times, which can make the elastic protrusion 320 more durable and more durable. In other embodiments, the elastic protrusion 320 and the hole wall of the mounting hole 3122 can also be fixed by glue bonding.

As shown in FIGS. 2 to 4, in this embodiment, the elastic protrusion 320 includes a bulge body 322 and a fixing ring 324 surrounding the bulge body 322 once. Specifically, in this embodiment, the bulge body 322 and the fixing ring 324 are integrally formed. In this way, the bulge body 322 and the fixing ring 324 are connected more tightly, and it is not easy to open the glue. At the same time, the assembly process can be saved, thereby saving assembly time. In other embodiments, the bulge body 322 and the fixing ring 324 may also be connected by glue bonding or screwing.

Wherein, the bulge body 322 penetrates the mounting hole 3122, and the fixing ring 324 extends into the hollow cavity 310c and abuts against an edge 3162 of the outer circumference of the mounting hole 3122 to close the end of the mounting hole 3122 close to the outer surface 310b. In this way, external dust can be prevented from entering the housing 310 through the mounting hole 3122. Moreover, when the housing 310 includes an inner housing 312 and an outer housing 314 that are detachably connected, the elastic protrusion 320 can be installed from the inner side of the inner housing 312 (the side close to the housing 314), which is very convenient for disassembly and assembly.

In this embodiment, the housing 310 includes a housing body and a mounting post 316. The shell body has a hollow structure, the inner side surface 310a and the outer side surface 310b are two side surfaces of the shell body, and the mounting post 316 is arranged in the shell body. Specifically, in this embodiment, the shell body includes an inner shell 312 and an outer shell 314 that are detachably connected, and the mounting post 316 is provided on the inner shell 312 and is located in the hollow cavity 310 c of the shell 310. Two ends of the mounting post 316 respectively correspond to the inner side surface 310a and the outer side surface 310b, and the mounting hole 3122 penetrates both ends of the mounting post 316. An edge 3162 on the outer circumference of the mounting hole 3122 is the end surface of the mounting hole 3122 away from the inner surface 310a. The mounting post 316 can make the mounting hole 3122 have a greater depth, and the elastic protrusion 320 with a larger size can be installed, and the elastic protrusion 320 can be deformed along the extension direction of the mounting hole 3122 when being squeezed. The protrusion 320 provides a predetermined deformation capacity, which is more conducive to firm wear.

In other embodiments, the mounting post 316 may be omitted. At this time, the mounting hole 3122 penetrates the shell wall of the inner shell 312. At this time, an edge 3162 of the outer periphery of the mounting hole 3122 is the wall surface of the inner shell 312, and the fixing ring 324 is connected to the inner shell 312. A ring of inner shell 312 on the outer circumference of the mounting hole 3122 is in contact with and sealed. Of course, the depth of the mounting hole 3122 can be increased by increasing the thickness of the shell wall of the inner shell 312.

In this embodiment, the connection between the part of the elastic protrusion 320 extending into the hollow cavity 310c and the housing 310 includes at least one of clamping, adhesive bonding, and screwing. In this way, not only can the fixing ring 324 and the peripheral edge of the mounting hole 3122 conflict and seal, but it is also very convenient for assembly.

Specifically, in this embodiment, a fixed post 318 is provided on the inner shell 312, and the fixed post 318 is provided with an internal threaded hole 3182. A matching post 326 is provided on the outer periphery of the fixing ring 324, and the matching post 326 is provided with a matching hole 3262. The housing 310 also includes screws.

In one embodiment, the end surface of the mating post 326 is in contact with the end surface of the fixing post 318, and the screw passes through the mating hole 3262 and is screwed to the internal threaded hole 3182 of the fixing post 318.

In one embodiment, the fixed post 318 is located on the outer periphery of the installation post 316 and is connected to the side of the installation post 316, and the height of the fixed post 318 is greater than the height of the installation post 316. The fixing post 318 passes through the fitting hole 3262, the screw is screwed with the internal threaded hole 3182 of the fixing post 318, and the size of the nut of the screw is larger than the size of the fitting hole 3262 to prevent the elastic protrusion 320 from falling off in the opposite direction. In this way, the fixing post 318 can not only fix the elastic protrusion 320 and play a fixed role, but also play a role in positioning the assembly of the elastic protrusion 320.

In this embodiment, the elastic protrusion 320 is separated from the inner shell 312 and fixed by screwing. In other embodiments, the elastic protrusion 320 and the inner shell 312 may also be integrally formed. In this way, the connection between the elastic protrusion 320 and the inner shell 312 can be made tighter, and at the same time, the assembly process can be saved, thereby saving assembly time.

In this embodiment, the rigidity of the outer shell 314 is greater than the rigidity of the elastic protrusion 320 and the inner shell 312, and the elastic protrusion 320 and the inner shell 312 are relatively soft. Specifically, in this embodiment, the materials of the elastic protrusion 320 and the inner shell 312 are both silica gel. Of course, in other embodiments, the material of the elastic protrusion 320 may be silica gel, and the material of the inner shell 312 may be harder plastic or the like.

In this embodiment, the end surface of the elastic protrusion 320 close to the outer side surface 310b is provided with a limiting member 328. The limit piece 328 has multiple uses.

In this embodiment, one function of the limiting member 328 is to interfere with the battery 14 provided in the housing 310 to restrict the movement of the battery 14. Another function of the stopper 328 is that when a gap 310d is formed between the stopper 328 and the side of the elastic protrusion 320 away from the outer surface 310b, the gap 310d provides a limited deformation space for the elastic protrusion 320 to avoid the elastic protrusion 320 320 is excessively squeezed into the hollow cavity 310c and cannot be automatically restored. That is, the limiting member 328 has a certain width. Under the action of the squeezing force, the side of the elastic protrusion 320 away from the outer side surface 310b deforms toward the limiting member 328, and the limiting member 328 can prevent the elastic protrusion 320 from being further deformed. It is avoided that the elastic protrusion 320 is excessively squeezed into the hollow cavity 310c and cannot be automatically restored.

When the control main board 16 is provided in the casing 310, the limit member 328 is spaced from the control main board 16. In this way, the elastic protrusion 320 can be prevented from being excessively squeezed into the hollow cavity 310c and cannot be automatically restored, and the limiting member 328 can be prevented from squeezing the control main board 16 to damage the control main board 16.

That is, in this embodiment, the elastic protrusions 320 of the two clamp arm structures 300 (one clamp arm structure 300 is provided with the battery 14 and the other clamp arm structure 300 is provided with the control board 16) are provided with a positioning member 328. , The battery 14 collides with the stopper 328 of the corresponding elastic protrusion 320, and the control main board 16 is spaced from the stopper 328 of the corresponding elastic protrusion 320. The limiting member 328 of each arm structure 300 can prevent the elastic protrusion 320 from being excessively squeezed into the hollow cavity 310c and cannot be automatically restored.

In other embodiments, when the main purpose of the limiting member 328 is to prevent the elastic protrusion 320 from being excessively squeezed into the hollow cavity 310c and cannot be automatically restored, when the battery 14 is provided in the clamping arm structure 300, The battery 14 is directly used as the limiting member 328; and when the control main board 16 is provided in the clamp arm structure 300, the control main board 16 can be directly used as the limiting member 328.

In this embodiment, the height of the elastic protrusion 320 protruding from the inner surface 310a is 1-10 mm. In this way, it can be avoided that the height of the elastic protrusion 320 is too high to cause the center of gravity of the neck massager 10 to move backward and easily fall off, and it can be avoided that the height of the elastic protrusion 320 is too high to provide too much elasticity and thus cause tight clamping. In addition, It is avoided that the height of the elastic protrusion 320 is too high to reduce the suitable wearing size; and the height of the elastic protrusion 320 is too low, which will cause the arm clamping structure 300 to not be close to the neck and cannot be fixed to the neck. Preferably, the height of the elastic protrusion 320 protruding from the inner surface 310a is 4-7 mm.

In this embodiment, the elastic protrusion 320 is used for the side surface 3222 that is in contact with the clamped object to be a concave arc surface relative to the clamped object, that is, in the arrangement direction from the inner side surface 310a to the outer side surface 310b, The elastic protrusion 320 is arc-shaped. In this way, when the elastic protrusion 320 is squeezed, it deforms and gradually increases the contact area with the neck; at the same time, the arc-shaped arching can provide more elasticity and larger space, in addition to providing more elasticity, it can also place and protect elements. The device prevents the deformed elastic protrusion 320 from contacting the components in the housing 310, that is, it prevents the squeezing force from indirectly acting on the components in the housing 310 when the elastic protrusion 320 is squeezed.
