Description

Technical Field

[0001] This application belongs to the field of auxiliary support technology, specifically relating to a head support device and a limb support device. Background Technology

[0002] In some work scenarios, workers need to look up for extended periods, a posture that keeps the muscles in their neck and back of their head under constant tension. Prolonged muscle tension can easily lead to muscle spasms, causing not only significant discomfort and pain but also poor neck posture and cervical spine-related health problems, negatively impacting the worker's health. Therefore, workers wear head support devices to alleviate discomfort in their head and neck.

[0003] However, due to differences in physiological characteristics such as head size, neck length, and body shape among different users, the head support devices in related technologies are difficult to flexibly adjust the relative distance between the headrest and the user's head. They cannot match the physiological parameters and usage habits of different users, which makes it difficult for the head support devices to adapt to users of different body types, thereby reducing the wearing comfort and versatility of the head support devices. Summary of the Invention

[0004] The purpose of this application is to provide a head support device and a limb support device that can solve the problems of low wearing comfort and versatility of head support devices in related technologies.

[0005] In a first aspect, embodiments of this application provide a head support device, the head support device comprising: A fastening component for attaching to the shoulder area of ​​the human body; A head support assembly is located at the rear of the fixing assembly and is used to support the human head; An adjustment mechanism is connected to both the fixing component and the head support component. The adjustment mechanism is configured to allow the head support component to be adjusted relative to the fixing component in at least two dimensions, and to fix the head support component relative to the fixing component after the head support component has been adjusted. The adjustment of at least two dimensions includes: The position of the head support component relative to the fixing component in the vertical direction is adjusted; The tilt angle of the head support component relative to the fixing component in the front-to-back direction is adjusted.

[0006] Secondly, embodiments of this application also provide a limb support device, which includes an arm support device and the aforementioned head support device. The arm support device is used to support the arm of a human body and is connected to the head support device.

[0007] In this embodiment, the fixing component is attached to the shoulder of the user, providing a stable wearing base and force support for the entire head support device. The head support component is located at the rear of the fixing component and can directly fit and support the user's head. When the user performs prolonged head-raising work, the weight of the head can be transferred through the head support component to the fixing component, and then from the fixing component to the shoulder. This effectively distributes the force on the muscles of the neck and back of the head, preventing the muscles of the neck and back of the head from being continuously stretched and compressed, thereby effectively reducing muscle spasms and pain.

[0008] The adjustment mechanism can be connected to both the fixed component and the head support component. The mechanism is configured to allow the head support component to be adjusted relative to the fixed component in at least two dimensions, and to fix the head support component relative to the fixed component after adjustment. This design allows for flexible adjustment of the head support component while ensuring it remains relatively fixed after adjustment, preventing displacement or angular shift due to body movement, head support force, or other factors during use, thus ensuring the stability of the head support component.

[0009] In this embodiment, the adjustable design of the head support component in at least two directions allows the head support device to adapt to users with different body types, head sizes, and work habits, effectively improving the versatility of the head support device. Furthermore, by adjusting the head support component, the fit between the head support component and the head can be improved, effectively enhancing the comfort of wearing it for extended periods and ensuring a better user experience during work.

Detailed Implementation

[0012] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0013] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0014] The head support device and limb support device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0015] refer to Figures 1-10 The head support device provided in this application embodiment may include a fixing component 100, a head support component 200, and an adjustment mechanism 1200.

[0016] like Figure 11 As shown, the fixing component 100 can be attached to the shoulder of the human body, and the head support component 200 can be located at the rear of the fixing component 100 and can be used to support the head of the human body. The fixing component 100 can provide a stable wearing base and force fulcrum for the entire head support device. The head support component 200 is arranged at the rear of the fixing component 100 and can directly fit and support the user's head. When the user performs long-term head-raising work, the weight of the head can be transferred through the head support component 200 to the fixing component 100, and then from the fixing component 100 to the shoulder. This can effectively distribute the force on the muscles of the neck and the back of the head, avoid the continuous stretching and compression of the muscles of the neck and the back of the head, and thus effectively reduce muscle spasms, pain, etc.

[0017] The adjustment mechanism 1200 can be connected to both the fixed component 100 and the head support component 200. The adjustment mechanism 1200 can be configured to allow the head support component 200 to be adjusted relative to the fixed component 100 in at least two dimensions, and to fix the head support component 200 relative to the fixed component 100 after adjustment. This configuration allows for flexible adjustment of the head support component 200, adapting it to users of different body types, head sizes, and work habits, effectively improving the versatility and comfort of the head support device. Furthermore, after adjustment, the head support component 200 remains relatively fixed to the fixed component 100, preventing displacement or angular shift of the head support component 200 due to body movement, head support force, or other factors during use, thus ensuring the stability of the head support component 200.

[0018] The adjustment in at least two dimensions can include: adjusting the position of the head support component 200 relative to the fixed component 100 in the vertical direction a, and adjusting the tilt angle of the head support component 200 relative to the fixed component 100 in the front-back direction b. This design allows the user to adjust the head support component 200 to the optimal height to fit the back of their head based on their neck length, height, and body type; and the user can adjust the tilt angle of the head support component 200 according to their head size and the angle at which they are working with their head up, thus improving the fit between the head support component 200 and the back of the head and enhancing wearing comfort. It should be noted that vertical direction a refers to the up-and-down direction, and front-back direction b refers to the front-back direction relative to the human body.

[0019] In this embodiment, the head support component 200 is designed to be adjustable in both height and tilt angle, making it adaptable to users with different body types, head sizes, and work habits. This effectively improves the versatility of the head support component. Furthermore, by adjusting the height and tilt angle of the head support component 200, the head support component 200 can fit the head better, effectively improving the comfort of wearing it for extended periods and ensuring a better user experience during work.

[0020] Optionally, the adjustment in at least two dimensions may further include: positional adjustment of the head support component 200 relative to the fixing component 100 in a first direction. The first direction may include at least one of the front-back direction b and the width direction c of the fixing component 100. This is beneficial for further improving the versatility of the head support device. It should be noted that the width direction c of the fixing component 100 is the left-right direction based on the human body.

[0021] In an optional embodiment, the adjustment mechanism 1200 may include a first fastening component 1000 and a second fastening component 1100.

[0022] The first fastening component 1000 can be connected to the fixing component 100 and the head support component 200 respectively. The first fastening component 1000 can switch between a loose state and a locked state. When the first fastening component 1000 is in the loose state, the first fastening component 1000 and the head support component 200 can move relative to each other in the vertical direction a. When the first fastening component 1000 is in the locked state, the first fastening component 1000 locks the head support component 200 and the fixing component 100.

[0023] When the first fastening component 1000 is in the loose state, the head support component 200 can move relative to the fixed component 100 in the vertical direction a, so that the head support component 200 can be adjusted in the vertical direction a relative to the fixed component 100. The user can adjust the head support component 200 to the optimal height to fit the back of their head according to their own neck length, height and body type. After adjustment, the first fastening component 1000 can be switched to the locked state to lock the head support component 200 and the fixed component 100, so that the head support component 200 is fixed at the required height.

[0024] The second fastening component 1100 can be mounted on the fixing component 100 and can be used to adjust the tilt angle of the head support component 200 in the front-back direction b. With this configuration, the user can adjust the tilt angle of the head support component 200 according to their own head size and the angle of their head-raising operation, so that the head support component 200 fits the back of the head better, thereby improving wearing comfort.

[0025] In this embodiment, the head support component 200 can be double-fixed by the first fastening component 1000 and the second fastening component 1100, which can effectively improve the stability of the head support component 200 and effectively prevent the head support component 200 from shifting or deviating in angle during operation.

[0026] In other embodiments, the adjustment mechanism 1200 may also include only the second fastening component 1100, which can adjust the tilt angle of the head support component 200 in the front-back direction b, and the user can manually pull the head support component 200 to adjust its height in the vertical direction a. The second fastening component 1100 can fix the head support component 200 relative to the fixing component 100 so that the head support component 200 is maintained at the required height and the required tilt angle.

[0027] Alternatively, the adjustment mechanism 1200 may also include a telescopic rod and a rotating component disposed at the telescopic end of the telescopic rod. The telescopic rod is mounted on the fixed assembly 100, and the rotating component is connected to the head support assembly 200 and used to drive the head support assembly 200 to rotate in the front-rear direction b, thereby adjusting the tilt angle of the head support assembly 200. The telescopic rod, by driving the rotating component to move in the vertical direction a, can move the head support assembly 200 in the vertical direction a, thereby adjusting the height of the head support assembly 200. Here, the self-locking performance of the telescopic rod and the rotating component's own structure can fix the position of the head support assembly 200. Here, the telescopic rod can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, and the rotating component can be a motor or a damped rotating shaft.

[0028] In optional embodiments, such as Figure 6 As shown, the head support assembly 200 may be provided with a strip hole 2211, which extends along the vertical direction a. A portion of the first fastening assembly 1000 may be located within the strip hole 2211. When the first fastening assembly 1000 is in the loosened state, it slides with the head support assembly 200. In this embodiment, when the first fastening assembly 1000 switches to the loosened state, it no longer applies a locking force to the head support assembly 200. At this time, the head support assembly 200 can slide continuously along the vertical direction a relative to the first fastening assembly 1000 and the fixing assembly 100 via the strip hole 2211. There are no restrictions such as stops or slots during the sliding process, allowing the head support assembly 200 to stop at any height position within its stroke, thereby achieving stepless adjustment of the height of the head support assembly 200.

[0029] In other embodiments, the head support component 200 may not have the strip hole 2211. Instead, the head support component 200 may have multiple through holes, which may be distributed along the vertical direction a. The first fastening component 1000 may be selectively connected to any one of the through holes.

[0030] In optional embodiments, such as Figure 8As shown, the first fastening assembly 1000 may include a first connecting rod 1010 and a first locking member 1020. The first connecting rod 1010 can be connected to the fixing assembly 100, and one end of the first connecting rod 1010 can pass through the slotted hole 2211. The first connecting rod 1010 is movable relative to the slotted hole 2211. The first locking member 1020 can be threadedly connected to the first connecting rod 1010 and can be located on the side of the head support assembly 200 opposite to the fixing assembly 100. The first locking member 1020 can lock the head support assembly 200 onto the fixing assembly 100. Here, rotating the first locking member 1020 can switch the first fastening assembly 1000 between a loose state and a locked state. This configuration offers several advantages. First, the connection between the head support assembly 200 and the fixed assembly 100 is more stable than that of the head support assembly 200, which is held by the first clamping member and the first connecting rod 1010 and the fixing assembly 100. This effectively prevents the head support assembly 200 from shifting or loosening under external force. Second, by rotating the first locking member 1020, the head support assembly 200 can be released from its lock or locked in the desired position, making the adjustment simple and convenient.

[0031] In other embodiments, the first fastening component 1000 may also include a first clamping member and a second clamping member. The first clamping member and the second clamping member may be connected to the fixing component 100 respectively, and a clamping space for clamping the head support component 200 may be formed between the first clamping member and the second clamping member. By clamping the head support component 200 with the first clamping member and the second clamping member, the head support component 200 and the fixing component 100 can be fixedly connected.

[0032] Optionally, such as Figure 6 As shown, the first fastening assembly 1000 also includes a first washer 1030 sleeved on the first connecting rod 1010. The first washer 1030 is located between the first locking member 1020 and the head support assembly 200, and the diameter of the hole in the first washer 1030 is smaller than the width of the strip hole 2211, while the outer diameter of the first washer 1030 is larger than the width of the strip hole 2211. This configuration increases the contact area between the first fastening assembly 1000 and the head support assembly 200, thereby effectively improving the stability after locking and effectively preventing the head support assembly 200 from slipping or loosening during use.

[0033] In optional embodiments, such as Figure 8As shown, the second fastening assembly 1100 may include a second connecting rod 1110, an elastic element 1130, and a second locking element 1120. The second connecting rod 1110 may be connected to the fixing assembly 100. One end of the second connecting rod 1110 may pass through the slotted hole 2211. The second connecting rod 1110 may move relative to the slotted hole 2211, and the head support assembly 200 may rotate back and forth along the second connecting rod 1110. The elastic element 1130 may be sleeved on the second connecting rod 1110, and the elastic element 1130 may be pressed between the head support assembly 200 and the fixing assembly 100. The second locking element 1120 may be threadedly connected to the second connecting rod 1110 and may be located on the side of the head support assembly 200 away from the fixing assembly 100. When the second locking element 1120 rotates, it may press or release the head support assembly 200 to adjust the tilt angle of the head support assembly 200. Here, the second connecting rod 1110 can guide and limit the elastic element 1130 to prevent the elastic element 1130 from shifting.

[0034] In this embodiment, the elastic element 1130 is pressed between the head support assembly 200 and the fixing assembly 100, so that the elastic element 1130 can continuously provide pre-tightening force to the head support assembly 200, and cooperate with the second locking element 1120 to lock the head support assembly 200 at the required tilt angle. This can effectively prevent the head support assembly 200 from shifting or rebounding under its own weight, elasticity or other external forces, so that the head support assembly 200 can maintain the required tilt angle for a long time to continuously and stably support the head. Furthermore, the method of adjusting the tilt angle of the head support assembly 200 and keeping it at the desired angle by cooperating with the second locking member 1120, the second connecting rod 1110 and the elastic member 1130 is simpler in structure than the method of adjusting the tilt angle of the head support assembly 200 and keeping it at the desired angle by cooperating with the third clamping member and the fourth clamping member. Moreover, the tilt angle of the head support assembly 200 can be adjusted simply by rotating the second locking member 1120, making the operation simple and convenient.

[0035] In other embodiments, the second fastening assembly 1100 may include a third clamping member and a fourth clamping member, which are located on the front and rear sides of the head support assembly 200, respectively. Both the third and fourth clamping members can be connected to the fixing assembly 100 and can move relative to the fixing assembly 100 in the front-rear direction b. By adjusting the positions of the third and fourth clamping members in the front-rear direction b, the tilt angle of the head support assembly 200 in the front-rear direction b can be adjusted.

[0036] Optionally, such as Figure 6As shown, the second fastening assembly 1100 further includes a second washer 1140 and a third washer 1150 sleeved around the second connecting rod 1110. The second washer 1140 is located between the second locking member 1120 and the head support assembly 200, and the third washer 1150 is located between the head support assembly 200 and the elastic member 1130. The apertures of the second washer 1140 and the third washer 1150 are smaller than the width of the strip hole 2211, and the outer diameters of the second washer 1140 and the third washer 1150 are larger than the width of the strip hole 2211. This configuration increases the contact area between the second fastening assembly 1100 and the head support assembly 200, thereby effectively improving the stability after locking and preventing slippage or loosening of the head support assembly 200 during use.

[0037] In optional embodiments, such as Figure 1 and Figure 8 As shown, the second fastening component 1100 is located above the first fastening component 1000. This arrangement makes it easier to adjust the tilt angle of the head support component 200, and will not affect the adjustment of the tilt angle of the head support component 200 even when the first fastening component 1000 is in the locked state.

[0038] Of course, the second fastening component 1100 can be located below the first fastening component 1000.

[0039] In optional embodiments, such as Figure 2 , Figure 6 , Figure 8 and Figure 9 As shown, a first limiting plate 140 and a second limiting plate 150 may be provided on the fixing component 100, and the first limiting plate 140 and the second limiting plate 150 may be spaced apart along the width direction c of the fixing component 100. A portion of the head support component 200 may be located between the first limiting plate 140 and the second limiting plate 150, and the head support component 200 is respectively limited and engaged with the first limiting plate 140 and the second limiting plate 150 in the width direction c. With this configuration, when the height and tilt angle of the head support component 200 are adjusted, the first limiting plate 140 and the second limiting plate 150 can provide lateral constraints, so that no matter how the height and tilt angle of the head support component 200 change, the position of the head support component 200 in the width direction c of the fixing component 100 is always limited, and it is not easy for lateral displacement to occur during the adjustment process, ensuring that the movement trajectory of the head support component 200 is always aligned with the central area of ​​the back of the human head.

[0040] In other embodiments, the first limiting plate 140 and the second limiting plate 150 may not be provided on the fixing component 100.

[0041] In optional embodiments, such as Figure 1As shown, the head support assembly 200 may include a headrest 210 and an elastic connecting plate 220. The headrest 210 can be used to support the head, such as... Figure 5 and Figure 10 As shown, the elastic connecting plate 220 may include a first connecting plate 221, a second connecting plate 222 and a third connecting plate 223. The second connecting plate 222 and the first connecting plate 221 are spaced apart along the front-back direction b. The top end of the first connecting plate 221 is connected to the second connecting plate 222 through the third connecting plate 223. The first connecting plate 221 is connected to the adjustment mechanism 1200, and the second connecting plate 222 is connected to the headrest 210.

[0042] In this embodiment, the adjustment mechanism 1200 is connected to the first connecting plate 221. Since the first connecting plate 221 has a plate-like structure, it possesses a certain degree of elasticity, facilitating the adjustment mechanism 1200 to adjust the tilt angle of the first connecting plate 221, thereby adjusting the tilt angle of the head support assembly 200. Furthermore, because the second connecting plate 222 is spaced apart from the first connecting plate 221 and connected by a third connecting plate 223, the second connecting plate 222 has elastic deformation space in the front-back direction b. Thus, when the user is performing head-raising operations, the second connecting plate 222 can adaptively deform according to different head-raising angles, causing the headrest 210 to make fine adjustments to its position and angle. This allows the headrest 210 to better conform to the contour of the back of the head, improving the fit and evenness of support. Simultaneously, it can buffer the impact of head movements and operational vibrations, further alleviating muscle fatigue in the user's neck and back of the head, and improving the wearing comfort and fit of the head support device.

[0043] In other embodiments, the elastic connecting plate 220 may also include only the first connecting plate 221, and the headrest 210 may be connected to the top end of the first connecting plate 221.

[0044] In optional embodiments, such as Figure 5 As shown, the fixing component 100 may include a fastener 110, such as Figure 8As shown, the fixing member 110 may include a first bow-shaped member 111, a second bow-shaped member 112, and a bow-shaped member connecting portion 113. The first bow-shaped member 111 and the second bow-shaped member 112 may be spaced apart along the width direction c of the fixing component 100. The first bow-shaped member 111 and the second bow-shaped member 112 may be used to hang on the left and right shoulders of the human body, respectively. The rear part of the first bow-shaped member 111 and the rear part of the second bow-shaped member 112 may be connected through the bow-shaped member connecting portion 113. Furthermore, the adjustment mechanism 1200 may be connected to the bow-shaped member connecting portion 113. With this configuration, the head weight and external force transmitted from the head support component 200 can be evenly distributed to the left and right shoulders through the first bow-shaped member 111 and the second bow-shaped member 112, avoiding excessive local stress on one shoulder and effectively relieving shoulder fatigue and discomfort caused by pressure.

[0045] In other embodiments, the fastener 110 may also include only the first bow-shaped member 111 or the second bow-shaped member 112.

[0046] For example, the fastener 110 may be made of materials such as plastic or metal.

[0047] In some embodiments, such as Figure 8 As shown, a fixing seat 130 is provided on the bow-shaped connecting part 113. The first connecting rod 1010 and the second connecting rod 1110 are detachably provided on the fixing seat 130. For example, both the first connecting rod 1010 and the second connecting rod 1110 can be screws. The fixing seat 130 can be provided with a first fixing hole and a second fixing hole. The first connecting rod 1010 can pass through the first fixing hole and be threadedly connected to the first locking member 1020. The second connecting rod 1110 can pass through the second fixing hole and be connected to the second locking member 1120.

[0048] Furthermore, the first limiting plate 140 and the second limiting plate 150 are both disposed on the fixed base 130, and the first connecting rod 1010 and the second connecting rod 1110 are located between the first limiting plate 140 and the second limiting plate 150.

[0049] Optionally, such as Figure 9 As shown, a first fixing plate 131 can be provided on the fixing base 130, and a first fixing hole is provided on the first fixing plate 131. When the first fastening component 1000 is in the locked state, the first locking member 1020 and the first fixing plate 131 can clamp the head support component 200 to fix the head support component 200.

[0050] like Figure 9As shown, a second fixing plate 132 is also provided on the fixing base 130. A second fixing hole can be provided on the second fixing plate 132. The first end of the elastic member 1130 can abut against the second fixing plate 132, and the second end of the elastic member 1130 can abut against the head support assembly 200 through the third washer 1150, so as to be able to press against the head support assembly 200. Here, the elastic member 1130 can be a compression spring.

[0051] For example, in the front-to-back direction, the width of the second fixing plate 132 is smaller than the width of the first fixing plate 131, so as to reserve space for adjusting the tilt angle of the head support assembly 200, thereby facilitating the adjustment of the tilt angle of the head support assembly 200.

[0052] In optional embodiments, such as Figure 5 As shown, the fixing component 100 may further include a flexible sleeve 120, which can be fitted over the fixing member 110. This arrangement separates the fixing member 110 from the human body, effectively alleviating the pressure and friction of this rigid component 110 on the shoulders, back, chest, etc., preventing skin indentations, abrasions, etc., and improving wearing comfort. For example, the flexible sleeve 120 may be made of flexible materials such as silicone, sponge, fabric, or elastic rubber.

[0053] Of course, the fixed component 100 may also exclude the flexible sleeve 120.

[0054] Optionally, such as Figure 9 As shown, the upper wall of the flexible sleeve 120 may be provided with a first opening 121 and a second opening 122. The first opening 121 and the second opening 122 may be located near the bow-shaped member connecting portion 113. The first opening 121 allows the first bow-shaped member 111 to pass through and extend into the flexible sleeve 120, and the second opening 122 allows the second bow-shaped member 112 to pass through and extend into the flexible sleeve 120. This arrangement facilitates the assembly and disassembly of the fixing member 110 and the flexible sleeve 120.

[0055] Of course, the upper wall of the flexible sleeve 120 may not have the first opening 121 and the second opening 122.

[0056] In some embodiments, such as Figure 8 As shown, the first bow-shaped member 111 has first grooves 1111 on each of its two edges in the width direction of the fixing assembly 100. The flexible sleeve 120 includes a first flexible sleeve fitted over the first bow-shaped member 111. The first flexible sleeve has a first elastic band, which allows a portion of the first flexible sleeve to be embedded in the first groove 1111, thereby improving the connection stability between the first flexible sleeve and the first bow-shaped member 111. Figure 8As shown, the second bow-shaped member 112 has two second grooves 1121 respectively on its two edges in the width direction c of the fixing component 100. The flexible sleeve 120 also includes a second flexible sleeve sleeved outside the second bow-shaped member 112. The second flexible sleeve is provided with a second elastic band. The second elastic band can make part of the second flexible sleeve embedded in the second groove 1121 to improve the connection stability between the second flexible sleeve and the second bow-shaped member 112.

[0057] In optional embodiments, such as Figures 1-4 As shown, the head support device may also include a waist belt 300, a first connecting belt 400, a second connecting belt 500, a third connecting belt 600, and a fourth connecting belt 700.

[0058] The first connecting strap 400 and the second connecting strap 500 can both be located on the front side of the fixing component 100. The first end of the first connecting strap 400 and the first end of the second connecting strap 500 can be connected to the first bow-shaped member 111 and the second bow-shaped member 112 respectively. The second end of the first connecting strap 400 and the second end of the second connecting strap 500 can both be connected to the waist belt 300.

[0059] The third connecting belt 600 and the fourth connecting belt 700 can both be located on the rear side of the fixing component 100.

[0060] The first ends of the third connecting strap 600 and the fourth connecting strap 700 can both be connected to the bow-shaped connecting part 113; or, the first end of the third connecting strap 600 is connected to the first bow-shaped member 111, and the first end of the fourth connecting strap 700 is connected to the second bow-shaped member 112; the second ends of the third connecting strap 600 and the second end of the fourth connecting strap 700 can both be connected to the waist belt 300. With this configuration, the fixing component 100 is connected to the waist belt 300 by the first connecting strap 400, the second connecting strap 500, the third connecting strap 600, and the fourth connecting strap 700, which can significantly improve the fixing stability of the fixing component 100, thereby improving the fixing stability of the head support device. When the user makes large limb movements or is in a complex working environment, it can effectively prevent the head support device from rising, tilting forward, tilting backward, skewing, or even falling off, ensuring that the headrest 210 is always stably fitted to the back of the human head. At the same time, it can further distribute the weight of the head support device and external forces from the shoulders to the waist, reducing local stress and pressure on the shoulders, relieving shoulder fatigue caused by wearing it for a long time, and improving wearing comfort.

[0061] In other embodiments, the head support device may also exclude the waist belt 300, the first connecting belt 400, the second connecting belt 500, the third connecting belt 600, and the fourth connecting belt 700.

[0062] Optionally, such as Figure 3 and Figure 4As shown, the head support device may further include a first fastening band 800 and a second fastening band 900. Both the first fastening band 800 and the second fastening band 900 may be located on the front side of the fixing component 100. The first end of the first fastening band 800 may be connected to the first arched member 111, and the first end of the second fastening band 900 may be connected to the second arched member 112. The second ends of the first fastening band 800 and the second fastening band 900 are detachably connected. This configuration, through the connection of the first fastening band 800 and the second fastening band 900, forms a transverse constraint band on the front side of the fixing component 100, thereby constraining the first arched member 111 and the second arched member 112 in the width direction c of the fixing component 100, limiting the displacement of the first arched member 111 and the second arched member 112 to the left and right, and preventing the first arched member 111 and the second arched member 112 from slipping off the shoulder.

[0063] Of course, the head support device may also exclude the first fastening band 800 and the second fastening band 900.

[0064] Optionally, such as Figure 3 As shown, the front part of the first bow-shaped member 111 may be provided with a first fixing part 1112, and the front part of the second bow-shaped member 112 may be provided with a second fixing part 1122. The first end of the first connecting strap 400 and the first end of the second connecting strap 500 may be connected to the first fixing part 1112 and the second fixing part 1122 respectively, and the second end of the first connecting strap 400 and the second end of the second connecting strap 500 may both be connected to the waist belt 300.

[0065] The flexible sleeve 120 may also be provided with a third opening (not shown in the figure) and a fourth opening (not shown in the figure). The third connecting strap 600 and the fourth connecting strap 700 can both be located on the rear side of the fixing component 100. The first end of the third connecting strap 600 and the first end of the fourth connecting strap 700 can respectively pass through the third opening and the fourth opening and extend into the flexible sleeve 120, and can be connected to the first fixing part 1112 and the second fixing part 1122 respectively. The second end of the third connecting strap 600 and the second end of the fourth connecting strap 700 can both be connected to the waist belt 300. This arrangement reduces the number of connecting structures and allows the third connecting strap 600 and the fourth connecting strap 700 to extend to the front side of the fixing component 100, thereby facilitating the user to adjust the length of the third connecting strap 600 and the fourth connecting strap 700.

[0066] Optionally, the first end of the first fastening band 800 can be connected to the first fixing part 1112, and the second end of the second fastening band 900 can be connected to the second fixing part 1122. The second ends of the first fastening band 800 and the second ends of the second fastening band 900 are detachably connected.

[0067] Based on the head support device provided in the embodiments of this application, the embodiments of this application also provide a limb support device, which may include an arm support device and the head support device described in any of the above embodiments. (Refer to...) Figures 11-19 The arm support device is used to support the human arm, and the arm support device can be connected to the head support device.

[0068] The beneficial effects achieved by the limb support device provided in this application embodiment are consistent with the beneficial effects achieved by the head support device provided in this application embodiment, and will not be repeated here. At the same time, the arm support device of the limb support device can counteract the arm's own weight and external force, thereby relieving arm muscle fatigue, soreness, etc., and can distribute the weight and force of the arm to the head support device.

[0069] In optional embodiments, such as Figure 11 As shown, the arm support device may include a support member 1500, a first movable member 1300, a second movable member 1600, a third movable member 1700, a first connecting portion 1800, and an energy storage portion 1900. The first end of the first movable member 1300 is rotatably connected to the support member 1500, and the first movable member 1300 is used to connect to the arm. The first end of the second movable member 1600 is rotatably connected to the first movable member 1300. The first end of the third movable member 1700 is rotatably connected to the support member 1500, and the second end of the second movable member 1600 is rotatably connected to the third movable member 1700. The first connecting portion 1800 is disposed on the second movable member 1600 or the third movable member 1700. The first end of the energy storage portion 1900 is connected to the support member 1500, and the second end of the energy storage portion 1900 is connected to the first connecting portion 1800. After the user puts on the arm support device, the energy storage unit 1900 is in a taut state. The energy storage unit 1900 will apply an upward pulling force to the first connecting part 1800. For example, when the user's upper arm is in a horizontal position, when the upper arm is subjected to downward pressure, the first movable member 1300 will generate a downward rotational torque relative to the support member 1500. At this time, the second movable member 1600 will tend to move downward, thereby generating a downward rotational torque on the third movable member 1700. However, due to the pulling force of the energy storage unit 1900, the first connecting part 1800 will apply an upward pulling force to the second movable member 1600 and the third movable member 1700, thereby enabling the second movable member 1600 to effectively support the first movable member 1300, thereby improving the support effect on the arm.

[0070] The support member 1500, the first movable member 1300, the second movable member 1600, and the third movable member 1700 can all be rods. The arm support device may also include a shoulder strap 1400 and an arm strap 2300. The upper end of the support member 1500 is connected to the shoulder strap 1400, and the lower end of the support member 1500 is connected to the waist belt 300. One end of the first movable member 1300 is movably connected to the support member 1500, for example, one end of the first movable member 1300 is hinged to the upper end of the support member 1500 via a first hinge shaft 1940. The first movable member 1300 is used to connect to the arm, for example... One end of the first movable member 1300, away from the support member 1500, is connected to the armband portion 2300, which is wrapped around the user's upper arm. One end of the second movable member 1600 is movably connected to the first movable member 1300, and the other end is movably connected to the third movable member 1700. For example, the upper end of the second movable member 1600 is hinged to the rod of the first movable member 1300 via a second hinge shaft 1610. The lower end is hinged to the third movable member 1700 via the third hinge shaft 1620; one end of the third movable member 1700 is movably connected to the support member 1500, for example, the third movable member 1700 is hinged to the support member 1500 via the fourth hinge shaft 1720; the first connecting part 1800 is provided on the second movable member 1600 or the third movable member 1700, for example, the first connecting part 1800 can be provided on the second movable member 1600 at a position away from the first movable member 1300, or the first connecting part 1800 can be provided on the third movable member 1700; the first end of the energy storage part 1900 is connected to the support member 1500, for example, the first end of the energy storage part 1900 is connected to the support member 1500 at a position near the upper end, and the second end of the energy storage part 1900 is connected to the first connecting part 1800, that is, the connection position of the second end of the energy storage part 1900 can be located on the second movable member 1600 or the third movable member 1700. After the user wears the aforementioned arm support device and the arm is in a horizontal position, the positional relationship of each component is as follows: Figure 11 As shown; when the arm is in the lowered position, the positional relationship of each component is as follows: Figure 12 As shown, when the arm is in the raised position, the positional relationship of each component is as follows: Figure 13As shown, the energy storage unit 1900 is always taut regardless of the arm's position. The energy storage unit 1900 applies an upward pulling force to the first connecting part 1800. For example, when the user's upper arm is in a horizontal position, when the upper arm is subjected to downward pressure, the first movable member 1300 will generate a downward rotational torque relative to the supporting member 1500. At this time, the second movable member 1600 will tend to move downward, thereby generating a downward rotational torque on the third movable member 1700. However, due to the pulling force of the energy storage unit 1900, the first connecting part 1800 will apply an upward pulling force to the second movable member 1600 and the third movable member 1700, thereby enabling the second movable member 1600 to effectively support the first movable member 1300, thus improving the support effect on the arm.

[0071] In some embodiments, such as Figure 11 and Figure 12 As shown, the first connecting portion 1800 is movably connected to the second movable member 1600 or the third movable member 1700. The second movable member 1600 or the third movable member 1700 is provided with an adjusting member. For example, when the first connecting portion 1800 is movably connected to the second movable member 1600, the second movable member 1600 is provided with a corresponding adjusting member; when the first connecting portion 1800 is movably connected to the third movable member 1700, the third movable member 1700 is provided with a corresponding adjusting member. The position of the first connecting portion 1800 can be adjusted via the adjusting member to change the distance between the hinge axes of the first connecting portion 1800, the third movable member 1700, and the support member 1500. For example… Figure 11As shown, the first connecting part 1800 is movably connected to the third movable member 1700. The third movable member 1700 and the support member 1500 are relatively movably connected through the fourth hinge shaft 1720. When the first connecting part 1800 moves to the left, the distance between the first connecting part 1800 and the fourth hinge shaft 1720 can be increased, thereby increasing the pulling force of the energy storage part 1900 on the first connecting part 1800. When the first connecting part 1800 moves to the right, the distance between the first connecting part 1800 and the fourth hinge shaft 1720 can be decreased, thereby decreasing the pulling force of the energy storage part 1900 on the first connecting part 1800. In practical use, when it is necessary to lift a heavier object, the distance between the first connecting part 1800 and the fourth hinge shaft 1720 can be increased. Conversely, when the object is lighter, the distance between the first connecting part 1800 and the fourth hinge shaft 1720 can be decreased. It should be noted that the adjusting component can be automatically or manually adjusted. For example, the first connecting part 1800 can be moved by a linear motor. Furthermore, a pressure sensor can be installed on the first movable component 1300. The pressure sensor can detect and send the detected information to the controller. The controller then determines whether the pressure exceeds the first preset pressure value. If so, the first connecting part 1800 is moved away from the fourth hinge axis 1720 by the linear motor to increase the distance between the two. If the pressure is lower than the second preset pressure value, the first connecting part 1800 is moved towards the first hinge axis 1940 by the linear motor to decrease the distance between the two. The first preset pressure value is greater than the second preset pressure value.

[0072] In some embodiments, such as Figure 15 As shown, the adjusting component includes a threaded adjusting component 1710. A groove is provided on the third movable member 1700. The first connecting part 1800 is slidably connected to the groove via a slider. The threaded adjusting component 1710 is threadedly connected to the slider. For example... Figure 15 As shown, a groove is provided on one side of the third movable member 1700. The extension direction of the groove is parallel to the length direction of the third movable member 1700. The slider is placed in the groove. The slider is constrained by the groove and can only move, not rotate. One end of the first connecting part 1800 is connected to the slider, and the other end is located outside the groove. The threaded adjusting part 1710 passes through the third movable member 1700 from the end away from the supporting member 1500 and is threadedly connected to the slider. By turning the threaded adjusting part 1710, the movement of the slider can be adjusted, thereby adjusting the distance between the first connecting part 1800 and the fourth hinge shaft 1720.

[0073] In some embodiments, such as Figure 16As shown, the energy storage unit 1900 includes an elastic part 1910, a first pull rope 1920, and a second pull rope 1930. The elastic part 1910 can be a rubber band or a spring, and the first pull rope 1920 and the second pull rope 1930 can be steel wire ropes. One end of the first pull rope 1920 is connected to one end of the elastic part 1910, and the other end of the first pull rope 1920 is connected to or wound around the first connecting part 1800 to connect with the support member 1500 or the third movable member 1700. The first connecting part 1800 can be a pulley, and the first pull rope 1920 is wound around the pulley, that is, the pulley can provide first pull. Rope 1920 serves to change direction. For ease of connection, the first pull rope 1920 can be connected to the fourth hinge shaft 1720 of the third movable member 1700 and the support member 1500. Furthermore, when the third movable member 1700 is in a horizontal state, the height of the first connecting part 1800 is lower than the position of the fourth hinge shaft 1720. One end of the second pull rope 1930 is connected to the other end of the elastic part 1910. The other end of the second pull rope 1930 can be directly fixed to the support member 1500, or fixed to the first hinge shaft 1940 of the first movable member 1300 and the support member 1500. It should be noted that the above embodiment is described using the elastic part 1910 as an example. In addition, the energy storage part 1900 can be selected only as a pull rope. One end of the pull rope is connected to a winch. The winch can be installed on the support member 1500. The length of the pull rope can be controlled by the winch, so that the pull rope can apply tension to the first connecting part 1800. The winch can be used in conjunction with the pressure sensor and controller mentioned above.

[0074] In some embodiments, such as Figure 16As shown, the arm support device also includes a second connecting part 2000, which is disposed on the support member 1500 or the first movable member 1300. For example, the second connecting part 2000 can be disposed on the upper end of the support member 1500, or on the first movable member 1300. That is, the second connecting part 2000 can be located on the support member 1500 or the first movable member 1300. The first end of the energy storage part 1900 is wound around the first movable member 1300. The second connecting part 2000 is connected to the first movable member 1300. One end of the second pull rope 1930, away from the elastic part 1910, is wound around the second connecting part 2000 to connect to the first movable member 1300. For example, the second connecting part 2000 can be connected to the first hinge shaft 1940, and the end of the second pull rope 1930, away from the elastic part 1910, is connected to the second hinge shaft 1610 of the first movable member 1300 and the second movable member 1600. The energy storage part 1900 can apply a pulling force to the first movable member 1300. For example, when the user's upper arm is hanging down, when the user raises their upper arm, the energy storage part 1900 can apply an upward pulling force to the first movable member 1300, thereby providing assistance. When the user's upper arm is in a horizontal position, the energy storage part 1900 forms a Z-shape under the action of the first connecting part 1800 and the second connecting part 2000.

[0075] In some embodiments, the first connecting portion 1800 and the second connecting portion 2000 are preferably pulleys. The pulleys reduce friction on the energy storage unit 1900, thereby improving its service life. It should be noted that the pulley is only a preferred option; a cylinder can also be used for the first connecting portion 1800 and the second connecting portion 2000. Furthermore, to prevent the first pull rope 1920 and the second pull rope 1930 from detaching, a groove for accommodating the pull ropes can be provided on the outer periphery of the cylinder.

[0076] In some embodiments, the first movable member 1300 is an axially telescopic rod, for example, the telescopic rod includes multiple segments of rods that are sequentially connected. The telescopic rod can adapt to the needs of different users; for example, when the user's arm is long, the telescopic rod can be lengthened, and when the arm is short, the telescopic rod can be shortened. Figure 15 As shown, the first movable component 1300 includes a base rod 1310 and an arm connecting rod 1320. The base rod 1310 has a hollow structure inside. The arm connecting rod 1320 passes through the base rod 1310, and the end of the arm connecting rod 1320 extends out of the base rod 1310. The side wall of the base rod 1310 is provided with a plurality of connecting holes distributed along its axial direction. A spring pin can be provided on the side wall of the arm connecting rod 1320. The spring pin can be selectively engaged in one of the connecting holes to achieve axial fixation of the arm connecting rod 1320 relative to the base rod 1310.

[0077] In some embodiments, the first movable member 1300 is parallel to the third movable member 1700, and the second movable member 1600 is parallel to the support member 1500. The support member 1500, the first hinge shaft 1940, the first movable member 1300, the second hinge shaft 1610, the second movable member 1600, the third hinge shaft 1620, the third movable member 1700, and the fourth hinge shaft 1720 form a deformable parallelogram mechanism. One end of the first movable member 1300, away from the support member 1500, extends forward from the second movable member 1600 to facilitate connection with an arm.

[0078] In some embodiments, such as Figure 11 and Figure 15 As shown, a support portion is provided at one end of the support member 1500 away from the first movable member 1300. That is, the support portion extends downward relative to the horizontal position of the third movable member 1700. For example, the support portion is connected to the waist belt 300 so that the user's waist supports the support member 1500. The support member 1500 can be a square tube or a round tube, and its weight can be reduced by using a hollow structure.

[0079] In some embodiments, the support includes a support rod 1520 and a ball joint 1510. One end of the support rod 1520 is movably connected to the support member 1500 along the length extension direction of the support member 1500. For example, multiple axially distributed adjustment holes can be provided on the support rod 1520. A snap-fit ​​member 2240 is provided on the support member 1500. When the support rod 1520 moves in the vertical direction a, so that one of the adjustment holes corresponds to and snaps into the snap-fit ​​member 2240, the support rod 1520 can be fixed in the height direction. Alternatively, multiple axially distributed connection holes can be provided on the side wall of the support member 1500. The support rod 1520 can be fixed by passing a pin or screw through the connection holes on the support member 1500. The ball joint 1510 is provided at the other end of the support rod 1520. Correspondingly, such as Figure 11 As shown, the waist belt 300 is provided with a hinge support 310. The support member 1500 can move relative to the hinge support 310 through the ball joint 1510, thereby facilitating the user's body movements.

[0080] In some embodiments, such as Figure 14As shown, the arm support device has an energy storage unit 1900 on both its inner and outer sides. The inner side refers to the side closer to the user's body, and the outer side refers to the side away from the user's body. The two energy storage units 1900 improve the support stability of the arm support device and also provide a safety redundancy. For example, if one energy storage unit 1900 breaks, the other energy storage unit 1900 can still be used. To prevent the user from being pinched when the relative positions of the bars change, a protective shell 2100 can be provided on both the inner and outer sides of the arm support device.

[0081] In addition, during use, it can support one of the user's arms, or two sets can be set to support both arms separately.

[0082] In some embodiments, such as Figure 18 As shown, the support member 1500 includes a housing 2200, and the housing 2200 has a cavity for accommodating the energy storage unit 1900 and the second movable member 1600. The housing 2200 can support the first movable member 1300 and the third movable member 1700. Specifically, the housing 2200 includes a first shell 2210 and a second shell 2220. The first shell 2210 and the second shell 2220 are fixedly connected on one side. The right sides of the first shell 2210 and the second shell 2220 are connected by fasteners. A gap is left between the left and opposite sides of the first shell 2210 and the second shell 2220 to form the aforementioned cavity. The upper, left and lower sides of the first shell 2210 and the second shell 2220 are not closed to facilitate the movement of the first movable member 1300, the second movable member 1600 and the third movable member 1700.
