Preferred embodiments of the present application are further elaborated below in conjunction with the drawings of the present specification.
The embodiment of the application provides a neck support, and the neck support can be worn on the neck of a user for supporting the neck of the user and driving the head of the user to move.
For example, referring to fig. 1, 10 and 16 to 18, a neck support includes a support 1 for lifting a chin, one end of the support 1 is extended with a first strap 2, the other end is extended with a second strap 3, an area enclosed between the first strap 2 and the second strap 3 forms a wearing space into which a user's neck can enter, and the support 1 is worn on the user's neck. After the support piece 1 is worn on the neck of a user, the lower side of the support piece 1 is propped against the chest or the neck of the user, and the upper side of the support piece 1 is propped against the chin of the user, so that the chin of the user is lifted.
Referring to fig. 2-5, 11-15 and 17-18, the neck support further comprises a first winding portion 4, a second winding portion 5 and a regulating mechanism 6, wherein the first winding portion 4, the second winding portion 5 and the regulating mechanism 6 are all installed on the support 1, and the regulating mechanism 6 is used for driving the first winding portion 4 and the second winding portion 5 to rotate.
The first winding portion 4 can rotate relative to the support member 1, the first binding band 2 is connected to the first winding portion 4, and when the first winding portion 4 rotates relative to the support member 1, the first binding band 2 can be wound on the first winding portion 4 or the first binding band 2 wound on the first winding portion 4 can be released.
Similarly, the second winding portion 5 can rotate relative to the support 1, the second strap 3 is connected to the second winding portion 5, and when the second winding portion 5 rotates relative to the support 1, the second strap 3 can be wound on the second winding portion 5 or the second strap 3 wound on the second winding portion 5 can be released.
The regulating mechanism 6 is in transmission connection with the first winding portion 4 and the second winding portion 5, so that the regulating mechanism 6 can drive the first winding portion 4 and the second winding portion 5 to rotate, and the first winding portion 4 winds or releases the first binding band 2 and the second winding portion 5 winds or releases the second binding band 3.
In one embodiment, the neck brace contains the following patterns:
the regulating mechanism 6 can drive the first winding part 4 to rotate along the winding direction and the second winding part 5 to rotate along the releasing direction, or drive the first winding part 4 to rotate along the releasing direction and the second winding part 5 to rotate along the winding direction, and the first winding part 4 and the second winding part 5 are driven to rotate in different directions according to the regulating mechanism 6, so that the switching between the two parts is realized. In this mode, when the regulating mechanism 6 drives the first winding part 4 to rotate and the second winding part 5 to rotate, the support 1 swings relative to the neck of the user; this mode is referred to as a swing direction adjustment mode of the support member 1.
Specifically, when the regulating mechanism 6 drives the first winding portion 4 to rotate along the winding direction and drives the second winding portion 5 to rotate along the releasing direction, the first strap 2 connected to the first winding portion 4 is wound, so that the length of one end of the first strap 2 extending out of the support member 1 is shortened, the second strap 3 connected to the second winding portion 5 is released, so that the length of one end of the second strap 3 extending out of the support member 1 is lengthened, and the winding of the first strap 2 and the release of the second strap 3 are synchronously performed, so that the first strap 2 can pull the support member 1 to swing towards the first strap 2. On the contrary, when the regulating mechanism 6 drives the first winding part 4 to rotate along the releasing direction and drives the second winding part 5 to rotate along the winding direction, the second binding band 3 can pull the supporting piece 1 to swing towards the second binding band 3.
After the neck support is worn on the neck of a user, the neck support supports the chin of the user, so that when the support piece 1 is pulled to swing, the chin of the user placed on the support piece 1 swings along with the support piece 1, and bad states such as soreness and tingling, stiffness and the like of the cervical vertebra of the user are effectively improved.
In the above, when the regulating mechanism 6 drives the first winding portion 4 and the second winding portion 5 to rotate, the first winding portion 4 and the second winding portion 5 rotate synchronously, so that the length of the first strap 2 wound is equal to the length of the second strap 3 released, or the length of the first strap 2 released is equal to the length of the second strap 3 wound, therefore, when the regulating mechanism 6 is in the mode, the tightness degree of the neck support worn on the neck of the user can not be regulated, and only the swinging direction of the support piece 1 is regulated. In other words, when the regulating mechanism 6 is in this mode, the regulating mechanism 6 is used to adjust the swing direction and swing amplitude of the chin of the user.
In one embodiment, the neck brace contains the following patterns:
the regulating mechanism 6 can drive the first winding part 4 and the second winding part 5 to rotate along the respective winding directions or rotate along the respective releasing directions, so that the supporting piece 1 can move forwards and backwards; this mode is referred to as a front-rear direction adjustment mode of the support member 1.
Specifically, when the regulating mechanism 6 drives the first winding portion 4 and the second winding portion 5 to rotate along respective winding directions, the first binding belt 2 connected to the first winding portion 4 and the second binding belt 3 connected to the second winding portion 5 are wound, so that the length of one end of the first binding belt 2 extending out of the support member 1 and the length of one end of the second binding belt 3 extending out of the support member 1 are shortened, and the support member 1 is pulled to move backwards. On the contrary, when the regulating mechanism 6 drives the first winding portion 4 and the second winding portion 5 to rotate along the respective releasing directions, the length of the end of the first binding band 2 extending out of the support member 1 and the length of the end of the second binding band 3 extending out of the support member 1 are both longer, so that the support member 1 can move forward.
In an embodiment, the neck support includes both the above-mentioned swing direction adjustment mode of the support and the fore-and-aft direction adjustment mode of the support, and can be switched between the two modes according to the needs of the user, i.e., the adjusting mechanism 6 includes a structure for switching between the two modes.
For example, referring to fig. 2-9 and fig. 11-13, the regulating mechanism 6 includes a regulating knob 61, a transmission mechanism 62, a reversing device 63 and a regulating member 64, where the regulating knob 61 is used to drive the first winding portion 4 and the second winding portion 5 to rotate, and the transmission mechanism 62 can transmit the torque of the regulating knob 61 to the first winding portion 4 to realize that the regulating knob 61 drives the first winding portion 4 to rotate; the reversing device 63 can transmit the torque of the adjusting knob 61 to the second winding part 5, so that the adjusting knob 61 drives the second winding part 5 to rotate; the adjusting piece 64 is used for driving the reversing device 63 to switch the transmission direction, and switching the direction mode of the adjusting support piece 1 and the tightness mode of the binding band of the adjusting support piece 1 is realized.
Specifically, the adjusting knob 61 is disposed on the support member 1, and the adjusting knob 61 can rotate relative to the support member 1, i.e., the adjusting knob 61 is rotatably connected to the support member 1, so that a user can rotate the adjusting knob 61.
The transmission mechanism 62 is disposed between the adjusting knob 61 and the first winding portion 4, and is capable of transmitting the upper torque of the adjusting knob 61 to the first winding portion 4, that is, when the adjusting knob 61 is rotated, the first winding portion 4 can be rotated by the transmission mechanism 62. The adjusting knob 61 can rotate forward and also can rotate reversely, so as to drive the first winding part 4 to rotate in the direction of releasing the first binding band 2 and rotate in the direction of winding the first binding band 2. That is, the transmission mechanism 62 is drivingly connected between the adjustment knob 61 and the first winding portion 4, for driving the first winding portion 4 to rotate in the winding direction in response to the rotation of the adjustment knob 61 in the first direction, and driving the first winding portion 4 to rotate in the releasing direction in response to the rotation of the adjustment knob 61 in the second direction.
The reversing device 63 is disposed between the second winding portion 5 and the transmission mechanism 62, and is capable of transmitting the upper torque of the adjusting knob 61 to the second winding portion 5 through the transmission mechanism 62 and the reversing device 63, so that when the user rotates the adjusting knob 61, the user can synchronously rotate the first winding portion 4 and the second winding portion 5, that is, the threading lengths of the first binding band 2 and the second binding band 3 can be synchronously adjusted.
The transmission mechanism 62 is provided with a first power output end and a second power output end, the reversing device 63 is movably arranged on the support 1, namely the reversing device 63 can move relative to the support 1, and the corresponding movement of the reversing device 63 has a first position and a second position, and the first position and the second position of the reversing device 63 can be mutually switched in use. When the reversing device 63 is located at the first position, the reversing device 63 is connected between the first power output end and the second winding part 5, namely, the reversing device 63 drives between the first power output end and the second winding part 5, and when the reversing device 63 is located at the position, the neck support is located in the swinging direction adjusting mode of the support piece 1. When the reversing device 63 is located at the second position, the reversing device 63 is connected between the second power output end and the second winding part 5, that is, the reversing device 63 drives between the second power output end and the second winding part 5, and the neck support is in the front-rear direction adjusting mode of the support member 1.
The reversing device 63 is connected with an adjusting piece 64, and the adjusting piece 64 is used for driving the reversing device 63 to move to a first position and driving the reversing device 63 to move to a second position, namely, the adjusting piece 64 is used for switching the neck support between a swinging direction adjusting mode of the supporting piece 1 and a front-back direction adjusting mode of the supporting piece 1.
In detail, the transmission mechanism 62 includes a worm 621 and a first gear 621. The worm 621 is in driving connection with the adjusting knob 61, or the adjusting knob 61 is fixedly connected with the adjusting knob 61, the first toothed member 41 is disposed on the first winding portion 4, the first gear 621 is meshed with the first toothed member 41 and the worm 621, that is, the worm 621, the first gear 621 and the first toothed member 41 form gear transmission, so that when the user rotates the adjusting knob 61, the first winding portion 4 can be driven to rotate.
The transmission mechanism 62 further includes a second gear 623, the second gear 623 meshes with the first gear 621, and the second gear 623 serves as a first power output end. The second winding part 5 is provided with the second toothed member 51, the reversing device 63 includes a third toothed member 631, the third toothed member 631 is engaged with the second toothed member 51, and when the reversing device 63 is in the first position, the third toothed member 631 is also engaged with the second gear 623, so that the worm 621, the first gear 621, the second gear 623, the third toothed member 631 and the second toothed member 51 form a gear transmission, and when the user rotates the adjustment knob 61, the second winding part 5 can be driven to rotate, and the rotation direction of the first winding part 4 is the same as the rotation direction of the second winding part 5.
When the reversing device 63 is in the second position, the third toothed member 631 meshes with the worm 621 and the second toothed member 51, i.e. the worm 621 acts as said second power take-off, at which time the direction of rotation of the first winding portion 4 and the direction of rotation of the second winding portion 5 are reversed, since the third toothed member 631 and the first gear 621 mesh with the worm 621 simultaneously and the third toothed member 631 and the first gear 621 mesh on both sides of the worm 621, respectively.
Wherein, the winding direction and the releasing direction of the first winding part 4 can be set according to the requirement. When the winding direction and the releasing direction of the first winding portion 4 are set, the first binding band 2 connected to the first winding portion 4 is in a completely released state, then the first winding portion 4 is rotated, at this time, the first binding band 2 is wound, that is, the direction of rotating the first winding portion 4 at this time is the winding direction, and otherwise, the direction of rotating the first winding portion 4 is the releasing direction. Similarly, the winding direction and the releasing direction of the second winding portion 5 may be set as needed.
Since the transmission mechanism 62 includes the worm 621, during the gear transmission, only the first gear 621 and the third toothed member 631 can be transmitted in the direction from the worm 621, and not in the reverse direction. Therefore, the adjusting mechanism 6 has a self-locking function, so that after the rotation of the adjusting knob 61 is stopped, the worm 621, the first gear 621 and the third toothed member 631 all stop rotating, and when the first strap 2 and the second strap 3 are pulled, the worm 621, the first gear 621 and the third toothed member 631 cannot be driven to rotate.
Therefore, in the above-described configuration, since the two states that the rotation direction of the first winding portion 4 and the rotation direction of the second winding portion 5 are the same and the rotation direction of the first winding portion 4 and the rotation direction of the second winding portion 5 are opposite can be achieved, the mode corresponding to the first position and the second position of the reversing device 63 is also determined after the user sets the winding direction and the releasing direction of the first winding portion 4 and the winding direction and the releasing direction of the second winding portion 5 as needed, that is, when the first position corresponds to the swing direction adjustment mode of the support 1, the second position corresponds to the front-rear direction adjustment mode of the support 1; or the first position corresponds to the front-rear adjustment mode of the support member 1, and the second position corresponds to the swing direction adjustment mode of the support member 1.
In another embodiment, the difference from the above embodiment is that the reversing device 63 includes a first transmission portion and a second transmission portion, where the first transmission portion and the second transmission portion are engaged with the transmission mechanism 62 at the same position, and the first transmission portion and the second transmission portion are not engaged with the transmission mechanism 62 at the same time, that is, when the first transmission portion is engaged with the transmission mechanism 62, the second transmission portion is in a non-engaged state with the transmission mechanism 62, whereas when the second transmission portion is engaged with the transmission mechanism 62, the first transmission portion is in a non-engaged state with the transmission mechanism 62. When the reversing device 63 is in the first position, the first transmission portion is engaged between the transmission mechanism 62 and the second winding portion 5, and the first transmission portion includes an odd number of gears, for example, 1, 3, 5, … …, so that one of the first winding portion 4 and the second winding portion 5 rotates in the winding direction and the other rotates in the releasing direction. When the reversing device 63 is in the second position, the second transmission portion is engaged between the transmission mechanism 62 and the second winding portion 5, and the first transmission portion includes an even number of gears, for example, 2, 4, and 6 … …, so that the first winding portion 4 and the second winding portion 5 rotate in the winding direction or rotate in the releasing direction.

Wherein the teeth of the third gear 6311 are adapted to the teeth of the second gear 623 and the teeth of the fourth gear 6312 are adapted to the teeth of the worm 621.
When the neck support only needs to have the front-rear adjustment mode of the support 1 or the swing direction adjustment mode of the support 1, the reversing device 63 does not need to have the first position and the second position to be switched, so the adjusting mechanism 6 comprises a worm 621, a first gear 621, a first toothed member 41, a fourth gear 6312 and a second toothed member 51, the first gear 621 is meshed between the worm 621 and the first toothed member 41, and the fourth gear 6312 is meshed between the worm 621 and the second toothed member 51; alternatively, the regulating mechanism 6 includes a worm 621, a first gear 621, a first toothed member 41, a second gear 623, a third gear 6311, and a second toothed member 51, the first gear 621 being meshed between the worm 621 and the first toothed member 41, the second gear 623 being meshed with the third gear 6311, and the third gear 6311 being meshed between the second gear 623 and the second toothed member 51.
