[0006] Furthermore, the rotation axes of the drive gear and the lead screw are staggered. The transmission structure includes an intermediate gear and a reversing gear that mesh with each other. The rotation axes of the intermediate gear and the reversing gear are staggered. The intermediate gear also meshes with the drive gear. The axis of the reversing gear is threaded to the corresponding lead screw, and the two lead screws rotate in opposite directions. The relative movement between the reversing gear and the lead screw simultaneously drives the two lead screws to rise and fall.

[0007] Furthermore, the base includes a base body and a cover assembly connected to the base body. The space between the base body and the cover assembly is used to install an adjustment mechanism. The two ends of the rotating shafts of the drive gear and the intermediate gear are rotatably connected to the base body and the cover assembly, respectively. The base body is provided with a slot for installing a lead screw and a mounting groove communicating with the slot. The mounting groove is located in the radial direction of the slot and is used to install a reversing gear.

[0008] Furthermore, the adjustment mechanism also includes a drive shaft, which is driven to an intermediate gear. The first end of the drive shaft is rotatably connected to the base body, and the second end of the drive shaft passes through the cover assembly.

[0013] Furthermore, the base body is provided with a limiting component, the guide component is provided with a limiting groove, and part of the limiting component is located within the limiting groove;

[0014] When the support body is raised to its limit position, the bottom of the limiting groove abuts against the limiting member to restrict the movement of the support body.

[0015] Furthermore, the base also includes a base sponge, which has a wearing hole for fitting around the user's neck, and the front end of the base sponge has a base.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model discloses a neck support, comprising a base and a support portion adjustable along the height direction connected to the base. The base contains an adjustment mechanism, which includes a drive gear and lead screws on both sides of the drive gear. One end of each lead screw is connected to the support portion, and a transmission mechanism connects the two lead screws and the drive gear. In use, driving the drive gear converts the circumferential driving force that drives the drive gear into an axial driving force that drives the lead screws to rise and fall synchronously, thus controlling the height of the support portion and allowing it to stop at any height. Compared to existing electrically driven technologies, the drive gear in this utility model can be manually driven, resulting in lower costs and making it more suitable for users' daily health maintenance and preventative use, enabling users to correct their posture over a certain period.

[0035] The following is combined with Figures 1-8 This utility model will be described in detail.

[0036] A neck brace includes a base and a support portion 40 adjustable along the height direction connected to the base, and an adjustment mechanism 50 disposed within the base. The adjustment mechanism 50 includes a drive gear 501, with lead screws 60 respectively provided on both sides of the drive gear 501. The same end of the two lead screws 60 is connected to the support portion 40. A transmission mechanism 502 is provided between the two lead screws 60 and the drive gear 501. The transmission mechanism 502 converts the circumferential driving force that drives the drive gear 501 to rotate circumferentially into an axial driving force that drives the lead screws 60 to rise and fall axially, so that the two lead screws 60 rise and fall synchronously to control the height at which the support portion 40 rests.

[0037] In use, the drive gear 501 is driven, and the transmission mechanism 502 converts the circumferential driving force that drives the drive gear 501 to rotate into the axial driving force that drives the lead screw 60 to rise and fall axially. This allows the two lead screws 60 to rise and fall synchronously to control the height at which the support part 40 stops, enabling it to stop at any height. Compared to existing technologies that use electric drives, the drive gear 501 in this invention can be manually driven, resulting in lower costs and making it more suitable for users' daily health care and preventative use needs, allowing users to correct their posture within a certain period.

[0038] like Figure 4As shown, the rotation axes of the driving gear 501 and the lead screw 60 are staggered. The transmission structure includes a meshing intermediate gear 5021 and a reversing gear 5022. The rotation axes of the intermediate gear 5021 and the reversing gear 5022 are staggered. Specifically, the rotation axes of the driving gear 501 and the lead screw 60 are at a 90-degree angle, and the included angle between the rotation axes of the intermediate gear 5021 and the reversing gear 5022 is also 90 degrees. The intermediate gear 5021 in the two transmission mechanisms 502 also meshes with the driving gear 501. The axes of the two reversing gears 5022 are respectively threaded to the corresponding lead screws 60, wherein the directions of rotation of the lead screws 60 are opposite. The relative movement between the reversing gears 5022 and the lead screws 60 simultaneously drives the two lead screws 60 to rise and fall.

[0039] In use, the drive gear 501 drives the intermediate gear 5021 to rotate, such as Figure 4 As shown, the two intermediate gears 5021 mesh with a reversing gear 5022 on the side away from the driving gear 501. At this time, the two reversing gears 5022 rotate in opposite directions. The reversing gear 5022 and the lead screw 60 are connected by a threaded transmission to achieve the lifting and lowering of the lead screw 60. If the two lead screws 60 need to rise or fall simultaneously, their rotation directions must be opposite. If the rotation directions of the two lead screws 60 are the same, one lead screw 60 will rise while the other falls, causing the support part 40 to malfunction. Furthermore, the reversing gear 5022 is provided with a connecting hole 50221, which is threadedly connected to the lead screw 60.

[0040] like Figure 1 As shown, the base includes a base body 10 and a cover assembly 20 connected to the base body 10. The space between the base body 10 and the cover assembly 20 is used to install the adjustment mechanism 50. The two ends of the rotating shafts of the drive gear 501 and the intermediate gear 5021 are rotatably connected to the base body 10 and the cover assembly 20, respectively. The base body 10 is provided with a slot 101 for mounting the lead screw 60 and a mounting groove 102 communicating with the slot 101. The mounting groove 102 is located in the radial direction of the slot 101 and is used to mount the reversing gear 5022. The mounting groove 102 restricts the axial movement of the reversing gear 5022, but does not restrict the circumferential rotation of the reversing gear 5022, so that the axial force generated when the reversing gear 5022 rotates is applied to the lead screw 60 through the threaded connection, thereby driving the lead screw 60 to rise and fall.

[0041] The adjustment mechanism 50 also includes a drive shaft 503, which is drively connected to the intermediate gear 5021 and forms the rotation shaft of the intermediate gear 5021. The first end of the drive shaft 503 is rotatably connected to the base body 10, and the second end of the drive shaft 503 passes through the cover assembly 20. A knob 70 is connected to the second end of the drive shaft 503 to drive the intermediate gear 5021 to rotate. Furthermore, the base body 10 is provided with a first receiving groove 801, and the cover assembly 20 is provided with a second receiving groove 802. A first bearing 901 and a second bearing 902 are respectively provided in the first receiving groove 801 and the second receiving groove 802. The first end of the drive shaft 503 passes through the first receiving groove 801 and is connected to the inner ring of the first bearing 901. The second end of the drive shaft 503 passes through the second receiving groove 802 and is connected to the inner ring of the second bearing 902. The function of the first bearing 901 and the second bearing 902 is to reduce the friction between the drive shaft 503 and the first receiving groove 801 and the second receiving groove 802 when the drive shaft 503 rotates, so that the user can more easily drive the drive shaft 503 to rotate through the knob 70, thereby driving the drive gear 501 to rotate.

[0042] like Figure 7 As shown, the drive shaft 503 includes a first section 5031 and a second section 5032 connected to each other. The first section 5031 is drively connected to the intermediate gear 5021. The end of the second section 5032 away from the first section 5031 is used to connect to the inner ring of the first bearing 901, and the second section 5032 is used to connect to the knob 70. The surfaces of the first section 5031 and the second section 5032 are provided with several slots 5033. The slots 5033 are connected to the intermediate gear 5021 and the knob 70 through a convex-concave fit, so that the knob 70 drives the drive shaft 503 to rotate, and the drive shaft 503 then drives the intermediate gear 5021 to rotate.

[0043] like Figure 1 As shown, the cover assembly 20 includes a cover body 201, with a groove 2011 on the outer side of the cover body 201. A second receiving groove 802 is provided within the groove 2011. A sponge layer 203 is provided on the outer surface of the cover assembly 20, with a notch 2031 adapted to the groove 2011. The cover assembly 20 also includes a pressure cap 202, which has a shape adapted to the groove 2011. The pressure cap 202 is disposed within the groove 2011, pressing the second bearing 902 into the second receiving groove 802. The second end of the drive shaft 503 passes through the cover body 201 and the pressure cap 202. A flange 2021 is provided on the outer side of the pressure cap 202, which covers the connection between the notch 2031 and the groove 2011 to enhance aesthetics. The pressure cap 202 is also provided with a placement groove 2022, and part of the knob 70 is installed in the placement groove 2022.

[0044] like Figure 1and Figure 5 As shown, the support part 40 includes a support body 401. Guide members 4011 are provided on both sides of the lower end face of the support body 401. The base body 10 is provided with a guide groove 103 adapted to the guide members 4011. The guide members 4011 are movably connected to the guide groove 103 along the height direction of the guide groove 103. Furthermore, a recess 40112 is provided on the inner side of the support body 401 to adapt to the user's neck and increase the contact area between the support body 401 and the user's chin. A supporting sponge 402 is provided on the upper end face of the support body 401, and an arc shape 4021 adapted to the recess 40112 is provided on the inner side of the supporting sponge 402 to improve the user's comfort.

[0045] The base body 10 is provided with a limiting member 100, and the guide member 4011 is provided with a limiting groove 40111. A portion of the limiting member 100 is located within the limiting groove 40111. Specifically, the first end of the limiting member 100 is provided with a fixed end 1001, which is connected to the base body 10. The second end of the limiting member 100 is provided with a limiting post 1002, which is inserted into the limiting groove 40111. When the support body 401 is raised to its limit position, the bottom of the limiting groove 40111 abuts against the limiting post 1002, thereby limiting the movement stroke of the support body 401 and preventing the support body 401 from rising too high and causing damage to the user.

[0046] like Figure 1 As shown, the base also includes a base sponge 30, which has a wearing hole 301 for fitting around the user's neck, and a base at the front end of the base sponge 30. The base sponge 30 distributes the downward force generated during the use of the neck brace to various parts of the user's shoulders, avoiding concentrated force that could cause discomfort to the user.

[0047] The neck support device proposed in this embodiment, taking the clockwise rotation of knob 70 to raise the support part 40 as an example, is used as follows:

[0048] After the neck brace is placed around the user's neck, the knob 70 is turned clockwise to drive the drive gear 501, which in turn drives the intermediate gear 5021 and the reversing gear 5022 in sequence. Because the mounting groove 102 restricts the axial movement of the reversing gear 5022 but not its circumferential rotation, the axial force generated by the rotation of the reversing gear 5022 is applied to the lead screw 60 through the threaded connection, driving the lead screw 60 to rise, which in turn drives the support part 40 to rise, thus supporting the user's neck. Once the support part 40 has risen to the appropriate position, the knob 70 can be stopped, and the rising part will then stop rising.

[0049] After use, turn the knob 70 counterclockwise, and the support 40 will drop down. The user can then remove the neck brace for the next use.

[0050] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
