Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
A neck massager 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 4. The neck massager 100 may be a low frequency neck massager. In the following description of the present application, the neck massager 100 will be described as a low frequency neck massager. The low-frequency neck massager can be a neck massager which emits low-frequency micro-current pulses below 1000 HZ. Of course, it will be understood by those skilled in the art that the neck massager 100 may be other types of neck massagers and is not limited to low frequency neck massagers.
As shown in fig. 1 to 3, a neck massager 100 according to an embodiment of the present invention includes an elastic support 1 and two clamping arms 2.
Specifically, the elastic support 1 includes a support body 11 and an elastic arm 12, and a mounting cavity is defined in the support body 11. For example, in the example of fig. 2 and 3, the bracket body 11 may include a bracket portion 111 and a decorative cover 112, and the bracket portion 111 and the decorative cover 112 may be snapped to each other to define a mounting cavity. Optionally, the bracket portion 111 is a silicone member, but is not limited thereto.
The resilient arm 12 is disposed within the mounting cavity. The elastic arm 12 includes at least one elastic segment 121, and the elastic segment 121 includes a plurality of protrusions 1211 sequentially connected in a length direction of the elastic stent 1, and each protrusion 1211 is formed by a portion of the elastic arm 12 protruding toward a direction away from a bending center (e.g., a center O in fig. 4) of the stent body 11. The two clamping arms 2 are respectively connected to two ends of the elastic support 1.
Referring to fig. 4, when the neck massage device 100, such as a low frequency neck massage device, is expanded by a force, the two ends of the elastic arm 12 are subjected to an outward expanding force F, and the elastic arm 12 tends to return to a free state, so that a normal reaction force F is generated at each point on the elastic arm 120. On the remaining parts of the spring arm 12, except for the spring segment 121, a normal reaction force f0Is directed toward the center O, and at each point on the plurality of protrusions 1211 of the resilient segment 121, except for generating a normal reaction force f directed toward the center O2In addition, a normal reaction force f toward the center B of the plurality of projection 12111. However, the convex portion 1211 generates a normal reaction force f toward the center O2Is smaller than the normal reaction force f generated when the convex portion 1211 is a smooth segment1. Thus, by using the elastic arm 12 provided with the plurality of projections 1211, the tendency of the elastic arm 12 to return to the free state as a whole becomes smaller.
When both ends of the elastic arm 12 are expanded, the overall curvature of the elastic arm 12 becomes smaller than that when not expanded, the curvature of the plurality of convex portions 1211 of the elastic section 121 also becomes smaller than that when not expanded, the tendency of the elastic arm 12 to return to the free state becomes smaller, and the reaction force against the expansion also becomes smaller, so that the elastic arm 12 is more easily expanded. At this time, the contraction clamping force of the elastic arm 12 and the expansion angle are in a nonlinear relationship, and the larger the expansion angle is, the smaller the rate of change of increase in the contraction clamping force of the elastic arm 12 is. Therefore, when a user with a large neck size wears the neck massage instrument 100, such as a low-frequency neck massage instrument, the counter force of the clamping effect generated when the elastic support 1 of the neck massage instrument 100, such as the low-frequency neck massage instrument, is unfolded and deformed can be effectively ensured not to be too large, and the use experience of the user with the large neck is improved.
According to the utility model discloses neck massage appearance 100 is for example low frequency neck massage appearance, through set up the elasticity section 121 that includes a plurality of bellyings 1211 that follow the length direction of elastic support 1 and link to each other in proper order on elastic arm 12, and make every bellyings 1211 formed by the partly bending center direction protrusion towards keeping away from support body 11 of elastic arm 12, guaranteed effectively that the great user of neck size is when wearing neck massage appearance 100 is for example low frequency neck massage appearance, the clamp force that produces when elastic support 1 expandes can not be too big, the user experience of the thicker user of neck has been promoted.
According to some embodiments of the present invention, each projection 1211 is formed in an arc-shaped structure protruding toward the direction away from the center of the above-mentioned curvature of the holder body 11. For example, as shown in fig. 2 to 4, each projection 1211 is formed by a portion of the elastic arm 12 projecting toward the decorative cover 112. Each projection 1211 coincides with the bending direction of the elastic arm 12 as a whole. So set up, processing is simple and with low costs.
Alternatively, as shown in fig. 4, the maximum distance between each protrusion 1211 and a side surface of the elastic segment 121 adjacent to the above-mentioned bending center of the stent body 11 is d, where d satisfies: d is more than or equal to 1mm and less than or equal to 10 mm. With this arrangement, while it is ensured that the clamping force generated when the elastic support 1 is unfolded will not be excessive, it is advantageous for the neck massage apparatus 100 such as a low frequency neck massage apparatus to be designed in a compact size. Specifically, for example, when the maximum distance d is less than 1mm, it is not well ensured that the clamping force generated when the elastic support 1 is unfolded is not excessively large; when the maximum distance d is greater than 10mm, the elastic arm 12 requires a larger installation space, thereby being disadvantageous to the miniaturization of the neck massage apparatus 100 such as a low frequency neck massage apparatus.
Further, the junction of two adjacent protrusions 1211 is located at one side of the center plane of the elastic arm 12. For example, referring to fig. 3 and 4, the lowest point of the connection of two adjacent protrusions 1211 is located at the center plane in the thickness direction of the elastic arm 12. Thus, it is better ensured that the clamping force when the neck massage apparatus 100, such as a low frequency neck massage apparatus, is unfolded is not excessive.
According to the present invention, as shown in fig. 2 and 4, the elastic segments 121 are multiple, and the elastic segments 121 are disposed along the length direction of the bracket body 11 at intervals. In the description of the present invention, "a plurality" means two or more. Further, the plurality of elastic segments 121 are evenly spaced along the length of the stent body 11. From this, through setting up a plurality of elastic segments 121, guarantee neck massage appearance 100 for example low frequency neck massage appearance when the atress expandes, the whole reaction force that produces of elastic arm 12 distributes and can be more even to the clamp force of having guaranteed to press from both sides tight neck can distribute evenly, has promoted the comfort when the user uses neck massage appearance 100.
Optionally, the resilient arm 12 is a plastic or metal piece. The plastic material is convenient to manufacture into various complicated shapes, so that the elastic arm 12 is convenient to form, and the processing is simple and the cost is low. The metal elastic arms 12 can better ensure the consistency of the mechanical properties thereof, and ensure the consistency of the properties of the elastic arms 12 in mass production. But is not limited thereto.
According to a further embodiment of the present invention, as shown in fig. 2-4, the elastic arm 12 further comprises at least one thinned section 122, wherein the thickness of the thinned section 122 is smaller than the thickness of the rest of the elastic arm 12. Therefore, according to the principle of the direct proportional relation of the same material, the same shape thickness and the bending deformation resistance, the local thickness is reduced, the reaction force of the elastic arm 12 which returns to the free shape when deforming can be reduced, and the nonlinear relation of the inward contraction clamping force and the unfolding angle of the elastic support 1 is more obvious.
Further, when the elastic arm 12 is made of a metal material, the local thickness can be reduced by etching. When the elastic arm 12 is made of plastic material, the elastic arm 12 can be partially thinned by using a mold forming method.
Optionally, there are two thinning sections 122, and the two thinning sections 122 are respectively located at two sides of the at least one elastic section 121. For example, referring to fig. 2 and 3, two thinning sections 122 are symmetrically disposed at left and right ends of the opening of the elastic arm 12, in which case the two thinning sections 122 are located at left and right ends of all the elastic sections 121. By such arrangement, the elastic arm 12 can be uniformly stressed.
According to some embodiments of the present invention, as shown in fig. 2 and 3, the neck massager 100 further includes a sponge member 3, the sponge member 3 is provided in the installation cavity, and the sponge member 3 is located on an inner side surface (e.g., a lower side in fig. 3) of the elastic arm 12. Therefore, the sponge member 3 can space the elastic arms 12 from the inner surface of the holder portion 111, so that the holder portion 111 can be prevented from being depressed inward, and the appearance of the neck massager 100 can be kept full.
