Detailed Description

Embodiments of the present invention will be described in detail below, by way of example with reference to the accompanying drawings.

A neck massager 10 according to an embodiment of the present invention is described below with reference to fig. 1-17.

As shown in fig. 1, the folding device comprises a middle bracket 11 and two clamping arms 13, wherein the middle bracket 11 is arc-shaped and surrounds a containing space, the clamping arms 13 are rotatably connected to two ends of the middle bracket 11, the two clamping arms 13 can be switched between an unfolding state and a folding state, at least one of the two clamping arms 13 in the folding state rotates into the containing space, one clamping arm 13 in the folding state, which is closer to the middle bracket 11, rotates into the containing space to be in a folding limit folding position, the other clamping arm 13 is superposed on the outer side face of the clamping arm 13, which is closer to the middle bracket 11, and the other clamping arm 13 is in a travelling path towards the folding limit folding position, so that the clamping arm 13, which is closer to the middle bracket 11, is pushed to stay in the folding state stably. The clip arms 13 are rotated into the receiving space when in the folded state and the two clip arms 13 are rotatable to be overlapped with each other, and the two clip arms 13 stably stay in the folded state by being overlapped with each other.

The fact that the two arms 13 stay in the folded state stably means that the arms 13 in the folded state do not spontaneously switch to the unfolded state due to their own weight, but rather, a certain external force is applied to the arms to be unfolded outwards.

Illustratively, the principle of the two clamp arms 13 resting stably in the folded state by stacking is as follows: the first folded clamping arm 13 is in a limit folding position which can be folded, but a certain and slight shaking allowance exists, and can not independently and permanently stay in the limit folding position, at the moment, the clamping arm 13 is almost disappeared under the action of the elastic piece 111 (see in detail below) (see fig. 8); the folded-back clip arms 13 are stacked on the outer side surfaces of the folded-back clip arms 13, so that the folded-back clip arms 13 are still in the travel path towards the limit folding positions to which the folded-back clip arms can be folded, and at the moment, the folded-back clip arms have a trend of continuing to fold towards the limit folding positions due to the acting force of the elastic pieces 111, so that the folded-back clip arms 13 can push the folded-back clip arms 13 to stably stay at the limit folding positions, thereby eliminating the folding shaking allowance of the folded-back clip arms 13, and meanwhile, the folded-back clip arms 13 also push the folded-back clip arms 13 reversely to balance the elastic acting force of the elastic pieces 111, so that the two clip arms 13 respectively stably stay in the folded state in the stacked postures.

It should be noted that, in other embodiments, the pre-folded arm 13 may not have a play margin, but the post-folded arm 13 may still push the pre-folded arm 13 through the stacked posture to stay in the limit folded position more stably, which also falls into the protection scope of the present application.

The clip arms 13 which are folded first in the folded state have a certain free swinging allowance with smaller amplitude, and the design has the advantages that the free swinging allowance can effectively absorb the vibration generated by folding the clip arms 13, the vibration cannot rigidly collide with the middle support 11 or the components arranged on the middle support 11 due to direct folding in place during folding, the collision between the two clip arms 13 caused by mutual superposition can also be buffered to a certain extent, and the service life of the neck massager 10 can be effectively prolonged. In addition, because free shaking allowance exists between the clamp arms 13 folded firstly and the middle support 11, folding interference does not exist for the clamp arms 13 folded afterwards, the problem that the folding sequence of the clamp arms 13 needs to be set because the folding positions of the two clamp arms 13 are single does not exist, and the folding experience of a user is improved.

It should be noted that, the arms 13 may be rotated to a folded state and an unfolded state, in the folded state, the two arms 13 are rotated relative to the middle bracket 11 so that the neck massage apparatus 10 is folded, specifically, the left end of the middle bracket 11 may be rotatably connected to the left arm 13, the right end of the middle bracket 11 may be rotatably connected to the right arm 13, when the left arm 13 is rotated to the folded state first and the right arm 13 is rotated to the folded state later, the inner surface of the left arm 13 faces and approaches the inner surface of the middle bracket 11, and the inner surface of the right arm 13 approaches the outer surface of the left arm 13, so that the right arm 13 and the left arm 13 are sequentially distributed from inside to outside in the folded state, and the two arms 13 form a stacked structure. Thus, the neck massager 10 has relatively small occupied space in the folded state, and the neck massager 10 is convenient to carry; meanwhile, when the neck massager 10 is needed, the laminated clamping arms 13 can be quickly unfolded to be in an unfolded state, so that the neck massager 10 can be quickly converted, and the neck massager 10 is more convenient to use.

Further, the inward folding arm clamps 13 can let the intermediate support 11 protect the arm clamps 13 to improve the stability of neck massage appearance 10 when carrying, simultaneously because neck massage appearance 10 is whole to encircle the shape of neck, the outer end of arm clamps 13 is the arc, makes the arm clamps 13 that inwards fold the accomodate more laminate neck massage appearance 10 than the arm clamps 13 that outwards fold the accomodate, and neck massage appearance 10 after folding occupies the space less, and neck massage appearance 10 stability after folding is higher.

Therefore, the neck massager 10 is fully utilized by folding the clamp arms 13 into the accommodating space, the neck massager 10 after the neck massager 10 is folded occupies a small space, the neck massager 10 is convenient to carry, the stability of the neck massager 10 can be improved, the clamp arms 13 are layered when the clamp arms 13 are folded, at least one clamp arm 13 is positioned in the accommodating space, and the other clamp arm 13 is abutted against the outer side of the clamp arm 13 positioned in the accommodating space, so that the occupied space of the neck massager 10 in the folded state is small, and the neck massager 10 is attractive after being folded.

In some embodiments, the clamp arm 13 is switchable between an extended state, in which the clamp arm 13 is in an extended position having a maximum angle with the intermediate bracket 11, and a collapsed state, in which the clamp arm 13 is in a collapsed position having a minimum angle with the intermediate bracket 11, and is stable in either state.

It will be understood that the angles between the two arms 13 in the folded state and the middle bracket 11 are not necessarily the same, and in the present embodiment, the "in the folded state, the arms 13 are in the folded position with the smallest angle between the two arms and the middle bracket 11" means that in the folded state, the two arms 13 are in the folded position with the smallest angle between the two arms and the middle bracket 11, and the arms 13 cannot be folded further. The above-described "limit folding position" refers to a position where the single clip arm 13 is folded toward the intermediate bracket 11 to the greatest extent, and also refers to a position where the two clip arms 13 in the folded state are closer to the intermediate bracket 11, i.e., the clip arms 13 located on the inner side.

In this way, the clamping arm 13 is connected with the connecting piece 12, so that the clamping arm 13 can be folded towards the middle bracket 11 by taking the connecting piece 12 as the center of a circle, the neck massager 10 has a folded state and an unfolded state, and the clamping arm 13 of the neck massager 10 in the folded state is in the folded state, so that the neck massager 10 in the folded state occupies smaller space and is more convenient to carry; the clip arm 13 is connected with the intermediate bracket 11 by providing the connecting member 12, so that the clip arm 13 is more stable and firm when being fixed to the intermediate bracket.

In addition, the connecting piece 12 not only can play a role in connecting the clamping arm 13 and the middle support 11, but also can set the connecting piece 12 into a complete annular shape, at this time, the connecting piece 12 can play a role in decorating parts, and the surface of the connecting piece 12 can adopt a coating simulating metal texture so as to promote the texture of the neck massager 10 and enhance the aesthetic degree and individuation of the appearance.

As shown in fig. 1, any one of the clip arms 13 can stably stay in an expanded state in which the clip arm 13 is in an expanded position in which an angle with the intermediate bracket 11 is largest, and in a collapsed state in which the two clip arms 13 are each in a collapsed position in which an angle with the intermediate bracket 11 is smallest.

The neck massager 10, the clamping arms 13 and the connecting piece 12 jointly define a neck accommodating space, the middle support 11 can deform to enable the neck accommodating space to have a certain adjusting range, so that the range of the neck which can be matched with the neck massager 10 is enlarged, and meanwhile, the tightening sense of the neck when the neck massager 10 is worn is reduced. The clamp arm 13 can stably stay in the unfolding state and the folding state, so that the clamp arm 13 cannot be folded when in use to avoid the tightness when the neck is stressed, and cannot be unfolded when in storage to avoid the clamp arm 13 or the middle support 11 from being knocked.

Of course, the present invention is not limited thereto, and the clamping arm 13 may have a plurality of unfolding states, in which the opening angles of the clamping arm 13 are different to correspond to different clamping gears, so that the user can select the clamping gear with the most comfortable experience according to the neck thickness degree of the user.

In the embodiment shown in fig. 1, the neck massager 10 further comprises a connecting member 12, the connecting member 12 is detachably connected to the intermediate bracket 11, and the clamp arm 13 is pivotally connected to the connecting member 12. Specifically, the clamping arm 13 can be connected with the connecting piece 12 through a rotating shaft or a hinge, and the connecting piece 12 can be connected to the end part of the middle bracket 11 through a detachable connection mode such as plugging, clamping and the like, so that when any one of the clamping arm 13 or the connecting piece 12 is problematic or damaged, the connecting piece 12 and the clamping arm 13 can be directly and quickly detached integrally, and the maintenance and the replacement are convenient.

As shown in fig. 8, the neck massage apparatus 10 further includes an elastic member 111, a mounting bracket 112, and a fastener, one end of the mounting bracket 112 is pivotally connected to the connecting member 12 via a rotation shaft 122, the other end of the mounting bracket 112 is fixedly connected to the clip arm 13, and the elastic member 111 is fixed between the mounting bracket 112 and the clip arm 13 by the fastener 1113.

Thus, the elastic member 111 can be used to position the arm 13 in the folded state to prevent the arm 13 from returning to the unfolded state, and the elastic member 111 can also provide a stopping force for the arm 13 to stay in the unfolded state when the arm 13 moves from the folded state to the unfolded state. Thus, in the expanded state, the elastic member 111 applies a pre-tightening force to the clip arm 13, so that the clip arm 13 is prevented from being bent inward, and the clip arm 13 can stably stay in the expanded state, and the installation of the clip arm 13 can be further assisted by the installation of the installation bracket 112.

As shown in fig. 9, the elastic member 111 includes a fixing plate 1111 and an elastic piece 1112 connected to the fixing plate 1111, the elastic piece 1112 has a plurality of bends, the fixing plate 1111 and the mounting bracket 112 are fixed by a fastener 1113, the elastic piece 1112 is located between the fixing plate 1111 and the mounting bracket 112, and a free end of the elastic piece 1112 extends out of an end portion of the clip arm 13 and is in plug-in fit with the connecting member 12.

In this way, the fixing piece 1111 fixes the elastic piece 1112 on the mounting bracket 112, and meanwhile, because the elastic piece 1112 is provided with a plurality of bending sections, each bending section on the elastic piece 1112 can be deformed first and then to provide a stopping force for the clamping arm 13, so that the clamping arm 13 becomes more stable in the unfolded state.

In the specific example shown in fig. 8 to 10, the fastener 1113 includes a screw 1113a and a nut 1113b, the nut 1113b is fitted into the mounting bracket 112, the inner wall of the clip arm 13 has a fixing hole for positioning the head of the screw 1113a, and the screw 1113a passes through the fixing piece 1111 to be connected with the nut 1113 b.

Thus, the fastener 1113 is coupled to the clamp arm 13 by a threaded sleeve that is embedded in the mounting bracket 112, such that the fastener 1113 can fixedly couple the mounting bracket 112 to the clamp arm 13.

As shown in fig. 16 and 17, the elastic piece 1112 includes first to fourth bending sections 1112d connected in sequence, the first bending section 1112a is connected perpendicularly to the fixing piece 1111, the second bending section 1112b extends along the width direction of the fixing piece 1111 and gradually approaches the fixing piece 1111, the third bending section 1112c is disposed 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 extends in a direction away from the fixing piece 1111.

Thus, the elastic piece 1112 has a plurality of bends, each bending section lifting the deformability bending section of the elastic piece 1112.

In some embodiments, the mounting bracket 112 has an inclined slot 113 for receiving the resilient tab 1112, the bottom wall of the inclined slot 113 conforms to the shape of the second bending section 1112b, the fourth bending section 1112d extends out of the inclined slot 113, and the fourth bending section 1112d is in a deployed state in mating engagement with the connector 12.

Thus, the second bending section 1112b is engaged with the inclined groove 113 and is flush with the inclined groove 113, so that the mounting bracket 112 can be fixed more stably. The fourth bending section 1112d extends out of the inclined groove 113, so that the elastic piece 1112 provides fixing capability for the neck massager 10 when the neck massager 10 is in the unfolded state, and the clamping arm 13 is more firmly fixed with the neck massager 10.

As shown in fig. 8, the device further includes a torsion spring 114, wherein the torsion spring 114 is sleeved outside the rotation shaft 122, one end of the torsion spring 114 is abutted against the mounting bracket 112, the other end is abutted against the connecting member 12, the torsion spring 114 is configured to normally drive the clamping arm 13 to fold, and the elastic member 111 is configured to normally drive the clamping arm 13 to unfold.

In this way, the torsion spring 114 has a larger initial pre-tightening force, and the restoring deformation capability of the folded torsion spring 114 is increased, so that the clamp arm 13 can automatically return to the initial stable state.

In some embodiments, the mounting bracket 112 has mounting ears 1121 into which the rotation shaft 122 is inserted, and a mounting slot 1122 between the two mounting ears 1121 for receiving the torsion spring 114.

Accordingly, the mounting lugs 1121 and the mounting grooves 1122 can assist in the fixation of the rotation shaft 122, so that the fixation of the rotation shaft 122 is more stable, thereby raising the number of times the clip arm 13 is folded.

In the embodiment shown in fig. 9, the inner side of the connecting member 12 has a relief groove 121, so that the mounting bracket 112 extends into the relief groove 121 to be connected with the connecting member 12 through the rotation shaft 122 when the clip arm 13 rotates.

In this way, after the avoiding groove 121 extends into the mounting bracket 112, the connection between the connecting piece 12 and the clamping arm 13 is more fixed, so that the unfolding state of the clamping arm 13 is more stable, and the stability of the clamping arm 13 and the neck massager 10 in the unfolding state is increased.

In some embodiments, intermediate bracket 11 includes a spring arm 115, an end of spring arm 115 facing connector 12 is provided with a socket 1151, socket 1152 is defined in socket 1151, connector 12 is provided with a socket 123 extending toward spring arm 115, and socket 123 is inserted into socket 1152 and secured to socket 1151 by a screw 1113 a.

Further, the fixing of the socket 1152 to the socket 123 is not limited to this, but a fixing method such as a pin joint may be used, and fixing the socket 1151 with the screw 1113a may improve the fixing ability and the dismounting ability of the connector 12. Therefore, insert plate 123 extends into socket 1152 to connect with connector 12, so that flexible arm 115 is more securely fastened to connector 12.

In some embodiments, the end of the intermediate bracket 11 is provided with a butt joint portion 125, the butt joint portion 125 and the end of the intermediate bracket 11 form a step, the connecting member 12 has a slot 124, and the butt joint portion 125 extends into the slot 124 of the connecting member 12.

In this way, the step of the abutting portion 125 is matched with the slot 124, so that the middle bracket 11 and the clamping arm 13 are fixed together, the middle bracket 11 and the clamping arm 13 are fixed firmly, and the stability of the clamping arm 13 in the unfolded state is improved.

In some embodiments, the top end of the docking portion 125 has a limit groove 1251, and the slot 124 has a limit protrusion 1252 disposed therein, the limit protrusion 1252 being adapted to extend into the limit groove 1251.

Therefore, the limit groove 1251 can cooperate with the limit projection 1252 to achieve a use state of the neck fixing massager 10, thereby avoiding a dislocation of the connecting piece 12 due to circumferential displacement.

In some embodiments, the inner side of the end of the connector 12 facing the clip arm 13 has a rounded corner R.
