The utility model discloses a neck massager which can provide clamping force to clamp the neck of a user and is firm to wear.

Referring to fig. 1 to 3 together, a schematic structural view of a neck massager 100 according to an embodiment of the present invention is shown, the neck massager 100 includes a middle bracket 10, a clamping arm 20 and a torsion spring 30, the clamping arm 20 is rotatably connected to the middle bracket 10 through a rotating shaft 40, a first included angle α is formed between the clamping arm 20 and the middle bracket 10, the clamping arm 20 can rotate relative to the middle bracket 10 to switch between a first posture position and a second posture position, when the clamping arm 20 is switched from the first posture position (shown in fig. 1) to the second posture position (shown in fig. 2), the first included angle α is increased, the torsion spring 30 is sleeved on the rotating shaft 40, when the clamping arm 20 is switched from the first posture position to the second posture position under an external force, the clamping arm 20 and the middle bracket 10 press the torsion spring 30, and when the external force applied to the clamping arm 20 is removed, the torsion spring 30 is used for providing an elastic force to convert the clamping arm 20 from the second posture position to the first posture position.

Illustratively, the shaft 40 is provided to the intermediate bracket 10. In some other embodiments, the rotating shaft 40 may be disposed on the clamping arm 20, which is not limited in this embodiment.

When the clamping arm 20 is switched from the first posture position to the second posture position by an external force, the torsion spring 30 is used for providing a force for keeping the clamping arm 20 at the second posture position. Specifically, the torsion spring 30 provides an elastic force which is balanced with the external force applied to the clamping arm 20.

Specifically, as shown in fig. 1 and 2, the neck massager 100 has two clamping arms 20, namely a first clamping arm 20a and a second clamping arm 20b, wherein the middle bracket 10 is provided with a rotating shaft 40 at both ends thereof, and the first clamping arm 20a and the second clamping arm 20b are respectively rotatably connected to the rotating shaft 40 at both ends of the middle bracket 10. A wearing space a for wearing to the neck of the user is formed between the first clamping arm 20a, the second clamping arm 20b and the middle support 10, and the size of the wearing space a can be adjusted by rotating the first clamping arm 20a and/or the second clamping arm 20 b. Illustratively, taking the first clamping arm 20a as an example, when the first clamping arm 20a is rotated to increase a first included angle α between the first clamping arm 20a and the middle bracket 10, the space between the first clamping arm 20a and the second clamping arm 20b increases, and the wearing space a increases, otherwise, the wearing space a decreases. Generally, the first posture position is an initial position of the clamp arm 20, that is, a position of the clamp arm 20 relative to the middle bracket 10 when the clamp arm 20 is not subjected to an external force, the first included angle α is a fixed value (for example, may be a factory-set value), the second posture position is a position of the clamp arm 20 when the wearing space a of the neck massager 100 is adapted to the neck size of the user, that is, a use position, and the first included angle α is a floating value (determined according to the neck size of the user). The floating value is greater than the fixed value, and the floating value means that the first included angle α of the neck massager 100 is different when the neck massager is worn on the neck of different users.

That is to say, in the present embodiment, the clamping arm 20 can rotate relative to the middle bracket 10 to switch between the first posture position and the second posture position, so as to adjust the size of the first included angle α between the clamping arm 20 and the middle bracket 10, and further adjust the size of the wearing space a of the neck massager 100, which is beneficial for the neck massager 100 to adapt to the necks of different users. In addition, the first clamping arm 20a and the second clamping arm 20b can both rotate to adjust the size of the wearing space a, the adjustable range of the size of the wearing space a is large, and the neck massage apparatus 100 is suitable for a wide range of people.

Considering that the wearing space a of the neck massager 100 can be adapted to the size of the neck of the user when the clamping arms 20 rotate to the second posture position to fit the neck of the user, but the neck massager 100 is not matched with the neck of the user, and is matched with the shaft holes with the same outer diameter and inner diameter, and the relative positions of the neck massager 100 and the shaft holes are maintained only by the friction force between the shaft holes, so that the neck massager 100 is easily subjected to external force to move relatively, that is, when the neck massager 100 is in the second posture position and worn on the neck of the user, the neck massager 100 is easily subjected to external force to be separated from the neck of the user. Therefore, in the present embodiment, the torsion spring 30 is used to provide an elastic force, so that when the clip arms 20 are in the second posture position and are not subjected to an external force (for example, when the user has worn the neck), the second posture position is switched to the first posture position to reduce the size of the first included angle α, so as to reduce the wearing space a of the neck massager 100, and further provide a clamping force, so that the neck massager 100 is clamped on the neck of the user, and the wearing is firmer.

In practical use, a user can manually apply an acting force to rotate the clamping arms 20 relative to the middle support 10 to switch from a first posture position to a second posture position, wear the neck massager 100 on the neck of the user and remove the manually applied acting force, due to the blocking of the neck of the user, the distance between the first clamping arm 20a and the second clamping arm 20b is equal to the distance between two sides of the neck of the user, the first clamping arm 20a and the second clamping arm 20b respectively cling to two sides of the neck of the user, and cannot further rotate to reduce the distance between the two, the elastic acting force of the torsion spring 30 enables the clamping arms 20 to have a tendency of rotating from the second posture position to the first posture position, the elastic acting force of the torsion spring 30 is converted into a clamping force that the first clamping arm 20a and the second clamping arm 20b clamp two sides of the neck of the user, and the clamping force enables the neck massager 100 to clamp the neck of the user, the neck massager 100 is prevented from being separated from the neck of the user due to the external force.

In some embodiments, as shown in fig. 3 and 4, the torsion spring 30 includes an elastic portion 31, a first extending portion 32, and a second extending portion 33, the elastic portion 31 is sleeved on the rotating shaft 40, the first extending portion 32 and the second extending portion 33 are connected to the elastic portion 31, a second included angle β is formed between the second extending portion 33 and the first extending portion 32, the first extending portion 32 and the second extending portion 33 are respectively abutted against the middle bracket 10 and the clip arm 20, when the clip arm 20 is switched from the first posture position to the second posture position under the action of an external force, the second included angle β decreases, and the elastic portion 31 is configured to provide an elastic force to increase the second included angle β when the clip arm 20 is removed from the external force, so that the clip arm 20 is switched from the second posture position to the first posture position relative to the middle bracket 10. It can be understood that when the clamping arm 20 is switched from the first posture position to the second posture position by an external force, the first included angle α increases, the middle bracket 10 and the clamping arm 20 respectively press the first extending portion 32 and the second extending portion 33, the second included angle β between the first extending portion 32 and the second extending portion decreases, the first extending portion 32 and the second extending portion 33 elastically deform the elastic portion 31, at this time, the elastic force of the elastic portion 31 is balanced with the external force applied to the clamping arm 20, and the clamping arm 20 is maintained at the second posture position. When the external force applied to the clamping arm 20 is removed, the stress balance state of the clamping arm 20 is destroyed, the elastic portion 31 recovers elastic deformation, the elastic force thereof increases the second included angle β between the first extension portion 32 and the second extension portion 33, the first extension portion 32 and the second extension portion 33 transmit the elastic force to enable the middle bracket 10 and the clamping arm 20 to rotate relatively, and the first included angle α between the clamping arm 20 and the middle bracket 10 is reduced, so that the clamping arm 20 is switched from the second posture position to the first posture position. In some other embodiments, the first extension portion 32 and the second extension portion 33 abut against the clamping arm 20 and the middle bracket 10, respectively, and when the first included angle α increases, the positions of the clamping arm 20 and the middle bracket 10 pressing the torsion spring 30 are correspondingly adjusted to be that the clamping arm 20 presses the first extension portion 32 and the middle bracket 10 presses the second extension portion 33, which is not specifically limited in this embodiment.

Optionally, the second included angle is less than 180 °.

For example, as shown in fig. 4, the torsion spring 30 has two elastic portions 31 and two second extending portions 33, the two elastic portions 31 are a first elastic portion 31a and a second elastic portion 31b, the first elastic portion 31a and the second elastic portion 31b are disposed at an interval, the first extending portion 32 is connected between the first elastic portion 31a and the second elastic portion 31b, one of the second extending portions 33 is connected to one end of the first elastic portion 31a far from the first extending portion 32, and the other second extending portion 33 is connected to one end of the second elastic portion 31b far from the first extending portion 32. Considering that the elastic part 31 applies a force to the rotation shaft 40 when being elastically deformed, and the rotation shaft 40 applies a reverse force (balanced with the above-mentioned force) to the elastic part 31 to maintain the position of the elastic part 31 with respect to the rotation shaft 40, the force applied to the rotation shaft 40 by the elastic part 31 is large. Therefore, in the present embodiment, the elastic portion 31 of the torsion spring 30 is designed as the first elastic portion 31a and the second elastic portion 31b which are arranged at intervals, so that the position of the acting force applied to the rotating shaft 40 by the elastic portion 31 of the torsion spring 30 is dispersed, the occurrence of the deformation of the rotating shaft 40 caused by the stress concentration is avoided, and the service life of the rotating shaft 40 is prolonged.

It can be understood that, on the basis that the elastic portion 31 of the torsion spring 30 is designed as the first elastic portion 31a and the second elastic portion 31b which are arranged at intervals, the first extending portion 32 is connected between the first elastic portion 31a and the second elastic portion 31b, and the two second extending portions 33 are respectively connected to one end of the first elastic portion 31a far away from the first extending portion 32 and one end of the second elastic portion 31b far away from the first extending portion 32, so that the torsion spring 30 is in a symmetrical structure as a whole. When the torsion spring 30 is subjected to the squeezing action of the middle bracket 10 and the clamping arm 20 or the torsion spring 30 applies an action force to the middle bracket 10 and the clamping arm 20, the resultant force of the two second extending portions 33 respectively positioned at the two ends of the whole torsion spring 30 is balanced with the force of the first extending portion 32 positioned in the middle of the whole torsion spring 30, and the two ends of a rod member are balanced with the middle of the rod member, and the rod member does not have a tendency of rotating with the middle of the rod member as a rotation center, that is, the torsion spring 30 does not have a tendency of rotating with the middle point between the first elastic portion 31a and the second elastic portion 31b as a rotation center, so that the situation that the torsion spring 30 applies an action force to the rotating shaft 40 due to the rotation tendency to cause the deformation of the rotating shaft 40 can be avoided.

Compared with the torsion spring 30 which adopts the single elastic part 31 and the first extension part 32 and the second extension part 33 are connected to the two ends of the elastic part 31, when the torsion spring 30 is subjected to the extrusion acting force of the middle bracket 10 and the clamping arm 20 or the torsion spring 30 applies acting force to the middle bracket 10 and the clamping arm 20, the two ends of a rod piece are stressed in balance, the rod piece has a tendency of rotating by taking the middle of the rod piece as a rotation center, namely, the torsion spring 30 has a tendency of rotating by taking the center of the single elastic part 31 as the rotation center, and the two ends of the torsion spring 30 extrude the rotating shaft 40, so that the risk of deformation of the rotating shaft 40 exists.

Specifically, the first elastic portion 31a and the second elastic portion 31b are both configured in a spring shape, the first extending portion 32 is configured in a U shape, two ends of the first extending portion 32 located at the U-shaped opening are respectively connected to one end of the first elastic portion 31a facing the second elastic portion 31b and one end of the second elastic portion 31b facing the first elastic portion 31a, the second extending portion 33 is configured in an L shape, wherein one end of one second extending portion 33 away from the first elastic portion 31a is opposite to and spaced apart from one end of the other extending portion away from the second elastic portion 31 b. It can be understood that the first extension portion 32 is U-shaped to increase the contact area between the first extension portion 32 and the middle bracket 10, so that the middle bracket 10 is stressed dispersedly and the middle bracket 10 is prevented from being damaged due to stress concentration, the two second extension portions 33 are L-shaped, wherein one end of one second extension portion 33 away from the first elastic portion 31a is opposite to one end of the other extension portion away from the second elastic portion 31b, so that the two second extension portions 33 can form a structure similar to the U-shaped of the first extension portion 32, so that the contact area between the second extension portion 33 and the clip arm 20 is increased, so that the clamping arm 20 is stressed dispersedly and the damage of the clip arm 20 due to stress concentration is prevented, wherein one end of one second extension portion 33 away from the first elastic portion 31a is spaced apart from one end of the other extension portion away from the second elastic portion 31b, the two second extending portions 33 can be prevented from interfering with each other.

In some embodiments, as shown in fig. 5, the middle bracket 10 includes a first housing portion 101 and a second housing portion 102, the second housing portion 102 is coupled to the first housing portion 101 in a covering manner, the clip arm 20 includes a third housing portion 201 and a fourth housing portion 202, and the fourth housing portion 202 is coupled to the third housing portion 201 in a covering manner. It can be known that, the design that middle support 10 and arm lock 20 of this embodiment all adopt two casing part lids to close, and support 10 and arm lock 20 in the middle of the dismouting of being convenient for reduce the installation degree of difficulty of pivot 40 and torsional spring 30, improve production efficiency.

Wherein, the first housing portion 101 is a portion of the middle bracket 10 facing the wearing space a of the neck massager 100, the second housing portion 102 is a portion of the middle bracket 10 facing away from the wearing space a, the third housing portion 201 is a portion of the clip arms 20 facing the wearing space a, and the fourth housing portion 202 is a portion of the clip arms 20 facing away from the wearing space a.

Further, a first stop 11 is protruded from an inner surface of the middle bracket 10, one end (a first extending portion 32) of the torsion spring 30 abuts against the first stop 11, a second stop 21 is protruded from an inner surface of the clip arm 20, and the other end (a second extending portion 33) of the torsion spring 30 abuts against the second stop 21. Specifically, the first baffle 11 is disposed on the inner surface of the first casing portion 101, the first baffle 11 extends from the first casing portion 101 to the second casing portion 102, the second baffle 21 is disposed on the inner surface of the third casing portion 201, and the second baffle 21 extends from the third casing portion 201 to the fourth casing portion 202.
