Detailed ways

The embodiments of the present disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are only used to explain the present disclosure, and cannot be understood as a limitation to the present disclosure.

It should be noted that the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of these features. Further, in the description of the present disclosure, unless otherwise specified, "plurality" means two or more than two.

The neck massager 10 according to an embodiment of the present disclosure will be described below with reference to FIGS. 1-17.

As shown in Figure 1, the neck massager 10 includes a middle bracket 11 and a first clip arm 13a and a second clip arm 13b. The middle bracket 11 is arc-shaped and surrounds the storage space. The first clip arm 13a and the second clip arm 13b are respectively rotatably connected to the two ends of the intermediate bracket 11, the state of the first clamp arm 13a and the second clamp arm 13b can be switched between the unfolded state and the folded state; wherein, in the folded state, the first clamp arm 13a Rotated into the storage space and in the first extreme folding position, the second clamping arm 13b is folded on the outer surface of the first clamping arm 13a, and the second clamping arm 13b is configured to push up the first when moving to the second extreme folding position. The clamping arm 13a is used to keep the first clamping arm 13a folded at the first extreme folding position; the first extreme folding position is the extreme position that the first clamping arm 13a can be folded to, and the second extreme folding position is the second clamping arm 13b The extreme position that can be folded to. When the first clamping arm 13a and the second clamping arm 13b are in the folded state, they are rotated into the storage space and the first clamping arm 13a and the second clamping arm 13b can be rotated to overlap each other, the first clamping arm 13a and the second clamping arm 13b Keep in a folded state by stacking on each other.

As mentioned above, maintaining the first clamping arm 13a and the second clamping arm 13b in the folded state means that the two clamping arms stably stay in the folded state, that is, the first clamping arm 13a and the second clamping arm 13b in the folded state are not in the folded state. It will spontaneously switch to the unfolded state due to its own gravity, but need to apply a certain external force to expand outward.

Exemplarily, the principle that the first clamping arm 13a and the second clamping arm 13b stay in the folded state stably by stacking is as follows: the first clamping arm 13a is in the limit folding position that can be folded, but there is a certain and slight amplitude Shaking margin, unable to rely on its own to achieve lasting stability and stay in the limit retracted position, at this time the first clamp arm 13a is almost disappeared by the force of the elastic member 111 (see below for details) (see Figure 8); the second clamp arm 13b is superimposed on the outer surface of the first clamping arm 13a, so that the second clamping arm 13b is still in the path of travel toward the ultimate collapsed position it can be folded to. At this time, the second clamping arm 13b is affected by the elastic member. The force of 111 has the tendency to continue to fold toward the limit collapsed position, so the second clamp arm 13b can push the first clamp arm 13a to stay in the limit collapsed position stably, so that the folding shaking margin of the first clamp arm 13a is eliminated, At the same time, the first clamping arm 13a also pushes against the second clamping arm 13b to balance the elastic force of the elastic member 111, so that the first clamping arm 13a and the second clamping arm 13b stay stably in a stacked posture. In the folded state.

It should be pointed out that in other embodiments, the first clamping arm 13a may not have a shaking margin, but the second clamping arm 13b can still push the first clamping arm 13a in a stacked posture to make it more stable. Staying in the extreme retracted position, this situation also falls within the scope of protection of this application.

The first clamp arm 13a in the folded state has a certain and small amplitude further free swing margin. The advantage of this design is that the free swing margin can effectively absorb the vibration generated by the folding of the first clamp arm 13a. When folded, there will be no rigid collision with the intermediate support 11 or the components provided on the intermediate support 11 due to the direct folding in place, and the collision between the first clamping arm 13a and the second clamping arm 13b due to the superposition of each other can also occur Obtaining a certain degree of cushioning can effectively extend the service life of the neck massager 10. In addition, since there is a margin of free swing between the first clamp arm 13a and the intermediate support 11, there will be no folding interference for the second clamp arm 13b, and there is no single folding position of the first clamp arm 13a and the second clamp arm 13b. However, it is necessary to set the folding sequence of the first clamping arm 13a and the second clamping arm 13b to improve the folding experience of the user.

It should be noted that the first clamp arm a and the second clamp arm 13b can be rotated to a folded state and an unfolded state. In the folded state, the first clamp arm 13a and the second clamp arm 13b rotate relative to the intermediate bracket 11 and then The neck massager 10 is folded. Specifically, the left end of the middle bracket 11 can be rotatably connected with the second clamping arm 13b, and the right end of the middle bracket 11 can be rotatably connected with the first clamping arm 13. The second clamping arm 13b is first rotated to the folded state, and then the first clamping arm is rotated. When the arm 13 is in the folded state, the inner surface of the second gripping arm 13b faces and is close to the inner surface of the intermediate support 11, and the inner surface of the first gripping arm 13 is close to the outer surface of the second gripping arm 13b. The clamping arm 13a and the second clamping arm 13b are sequentially distributed from the inside to the outside, and the first clamping arm 13a and the second clamping arm 13b form a laminated structure. Therefore, the neck massager 10 has a relatively small footprint in the folded state, and the neck massager 10 is more convenient to carry; at the same time, when the neck massager 10 needs to be used, the stacked first clamp arm 13a can be quickly unfolded , 13b to the unfolded state, the conversion is relatively rapid, and the neck massager 10 is more convenient to use.

Further, the first clamping arm 13a and the second clamping arm 13b that are folded inward can allow the intermediate bracket 11 to protect the first clamping arm 13a and the second clamping arm 13b, thereby improving the stability of the neck massager 10 when being carried. At the same time, because the neck massager 10 surrounds the neck as a whole, the outer ends of the first clamping arm 13a and the second clamping arm 13b are arc-shaped, so that the first clamping arm 13a and the second clamping arm 13b are folded inwardly to fit more closely The neck massager 10 thus occupies a smaller space, and the structure stability of the neck massager 10 after being folded is higher.

Therefore, according to the neck massager 10 of the embodiment of the present disclosure, by folding the first clamping arm 13a and the second clamping arm 13b into the storage space, not only the storage space inside the neck massager 10 is fully utilized, that is, , While the folded neck massager 10 occupies a small space and is convenient to carry, it can also increase the stability of the neck massager 10. In addition, the first clamping arm 13a and the second clamping arm 13b are folded into a layered shape, and The first clamping arm 13a is located in the storage space, and the second clamping arm 13b is close to the outside of the first clamping arm 13a, so that the neck massager 10 in the folded state occupies a small space and is beautiful.

In some embodiments, any one of the first clamp arm 13a and the second clamp arm 13b can be maintained in an unfolded state, and the first clamp arm 13a and the second clamp arm 13b are in the unfolded state when they are in contact with the intermediate support 11 In the folded state, the first clamping arm 13a and the second clamping arm 13b are respectively at the first and second ultimate collapsed positions where the angle between themselves and the intermediate bracket is the smallest. Collapse position.

It is understandable that the angles between the first clamp arm 13a and the second clamp arm 13b in the folded state and the intermediate bracket 11 are not necessarily the same. In this embodiment, "in the folded state, the first clamp arm 13a and the second clamp arm 13a The second clamp arm 13b is in the folded position with the smallest angle with the middle bracket 11" means that in the folded state, the first clamp arm 13a and the second clamp arm 13b are in the folded position with the smallest angle with the middle bracket 11, respectively. , The first clamping arm 13a and the second clamping arm 13b cannot be further folded. The "extreme folding position" mentioned above refers to the position where the single clip arm 13 or 13b is folded to the middle bracket 11 to the greatest extent, and also refers to the first clip arm 13a and the second clip arm 13b in the folded state. The middle is closer to the middle bracket 11, that is, the position of the clamp arm on the inner side.

In this way, the first clamping arm 13a and the second clamping arm 13b are connected to the connecting member 12, so that the first clamping arm 13a and the second clamping arm 13b can be folded in the direction of the middle bracket 11 with the connecting member 12 as the center, so that the neck The massager 10 has a folded state and an unfolded state. The first clamping arm 13a and the second clamping arm 13b of the neck massager 10 in the folded state are in the folded state, so that the neck massager 10 in the folded state occupies a smaller space. It is more convenient to carry; the first clamping arm 13a and the second clamping arm 13b are connected to the intermediate support 11 by the connecting member 12, so that the first clamping arm 13a and the second clamping arm 13b are more stable when being fixed to the intermediate support.

In addition, the connecting member 12 can not only play the role of connecting the first clamping arm 13a and the second clamping arm 13b with the intermediate bracket 11, but also the connecting member 12 can be arranged in a complete ring shape. At this time, the connecting member 12 can serve as a decorative part. effect. The surface of the connecting piece 12 can be coated with a metal-like texture to enhance the texture of the neck massager 10 and enhance the aesthetics and individuality of the appearance.

As shown in Figure 1, any one of the

clamp arms

13a, 13b can stay in the unfolded state stably. In the unfolded state, the

clamp arms

13a, 13b are in the unfolded position with the largest included angle with the intermediate support 11. In the folded state, the first The clamping arm 13a and the second clamping arm 13b are each in a folded position where the angle between itself and the intermediate bracket 11 is the smallest.

The middle bracket 11, the first clamping arm 13a, the second clamping arm 13b, and the connecting member 12 jointly define a neck accommodating space. The middle bracket 11 is deformable so that the neck accommodating space has a certain adjustment range, so that the neck massager 10 The range of neck that can be matched becomes larger, and at the same time, the tightness of the neck when wearing the neck massager 10 is reduced. The first clamp arm 13a and the second clamp arm 13b can be stably stayed in the unfolded state and folded state, so that the first clamp arm 13a and the second clamp arm 13b will not be folded during use to avoid stress on the neck It is tight when loose, and will not expand when storing to prevent the first clamping arm 13a and the second clamping arm 13b or the intermediate bracket 11 from being bumped.

Of course, the present invention is not limited to this. Each of the first clamp arm 13a and the second clamp arm 13b may also have a plurality of unfolded states. In the multiple unfolded states, the opening angles of the clamp arms are different to correspond to different Clamping gear, so that users can choose the most comfortable clamping gear according to the thickness of their neck.

In the specific embodiment shown in FIG. 1, the neck massager 10 further includes a connecting piece 12, which is detachably connected to the intermediate bracket 11, and the first clamping arm 13a and the second clamping arm 13b are respectively connected to the connecting piece 12 Pivot connection. Specifically, the first clamping arm 13a and the second clamping arm 13b can be connected to the connecting piece 12 through a rotating shaft or a hinge, and the connecting piece 12 can be connected to the end of the intermediate bracket 11 through a detachable connection method such as plug-in connection and clamping connection. In this way, when any one of the clamping arm and the connecting member 12 is faulty or damaged, the connecting member 12 and the clamping arm can be quickly removed as a whole, which is convenient for maintenance and replacement.

As shown in Figure 8, the neck massager 10 further includes an elastic member 111, a mounting bracket 112, and a fastener 1113. One end of the mounting bracket 112 is pivotally connected to the connecting member 12 by a rotating shaft 122, and the other end of the mounting bracket 112 is pivotally connected to the connecting member 12. The second clamping arm 13b is fixedly connected, and the elastic member 111 is fixed between the mounting bracket 112 and the second clamping arm 13b by a fastener 1113. This structure is also applicable to the first clamping arm 13a (not specifically shown).

Therefore, in the folded state, the elastic member 111 can be used to position the second clamping arm 13b, so as to prevent the second clamping arm 13b from returning to the unfolded state. The elastic member 111 can also provide an abutment force for the second clamping arm 13b to stay in the expanded state when the second clamping arm 13b is from the folded state to the expanded state. In this way, in the unfolded state, the elastic member 111 exerts a pretension force on the second clamp arm 13b to prevent the second clamp arm 13b from bending toward the inside so that the second clamp arm 13b can stably stay in the unfolded state, and the mounting bracket 112 The arrangement can further assist the installation of the second clamp arm 13b. The same applies to the first clamp arm 13a.

As shown in Figure 9, the elastic member 111 includes a fixing piece 1111 and an elastic piece 1112 connected to the fixing piece 1111. The elastic piece 1112 has multiple bends. The fixing piece 1111 and the mounting bracket 112 are fixed by a fastener 1113. The elastic piece 1112 Located between the fixing piece 1111 and the mounting bracket 112, the free end of the elastic piece 1112 protrudes from the end of the second clamping arm 13 b and is inserted and fitted with the connecting piece 12.

In this way, the fixing piece 1111 fixes the elastic piece 1112 on the mounting bracket 112, and at the same time, because the elastic piece 1112 is provided with multiple bending sections, each of the bending sections on the elastic piece 1112 can be deformed successively to form the second clamping arm. 13b provides a resistive force, so that the second clamp arm 13b becomes more stable in the unfolded state. The same applies to the first clamp arm 13a.

In the specific examples shown in FIGS. 8 to 10, the fastener 1113 includes a screw 1113a and a threaded sleeve 1113b. The screw sleeve 1113b is embedded in the mounting bracket 112, the inner wall of each of the first clamping arm 13a and the second clamping arm 13b has a fixing hole for positioning the head of the screw 1113a, and the screw 1113a passes through the fixing piece 1111 to connect with the screw sleeve. 1113b connection.

Therefore, the fastener 1113 is connected to the second clamping arm 13b through the screw sleeve embedded on the mounting bracket 112, so that the fastener 1113 can fixedly connect the mounting bracket 112 and the second clamping arm 13b. The same applies to the first clamp arm 13a.

As shown in Figures 16 and 17, the elastic sheet 1112 includes first to fourth bending sections 1112d connected in sequence. The first bending section 1112a is perpendicularly connected to the fixing sheet 1111, and the second bending section 1112b extends along the fixing sheet 1111. The width direction extends and gradually approaches the fixing piece 1111, the third bending section 1112c is arranged parallel to the first bending section 1112a and extends to be flush with the fixing piece 1111, and the fourth bending section 1112d is perpendicular to the third bending section 1112c And it extends in a direction away from the fixing piece 1111. In this way, by providing multiple bending sections on the elastic sheet 1112, the deformability of the elastic sheet 1112 can be improved.

In some embodiments, the mounting bracket 112 has an inclined groove 113 for accommodating the elastic sheet 1112, and the bottom wall of the inclined groove 113 conforms to the shape of the second bending section 1112b, and the fourth bending section 1112d extends out of the inclined groove 113 , And in the unfolded state, the fourth bending section 1112d and the connecting piece 12 are plug-in-fitted.

As a result, the second bending section 1112b and the inclined groove 113 are flush and fit, so that the mounting bracket 112 can be fixed more stably.
