Description

TECHNICAL FIELD

[0001] The present application belongs to the field of fitness and rehabilitation training equipment, and particularly relates to a wearable neck muscle training device. BACKGROUND

[0002] At present, the neck muscle training devices at home and abroad are mostly large mechanical devices, which need complex motor, hydraulic or pneumatic systems to provide adjustable resistance, and have defects such as high cost, complex structure, inconvenient maintenance, dependence on power supply, and inconvenience for home use and portable movement.

[0003] Although some rehabilitation equipment manufacturers have launched neck training supports and some simple mechanical neck training devices, such as head-mounted weight blocks or weight balls, and simple elastic band devices, they can usually only provide single-direction tension, and neck muscle training is more focused on dynamic training. The neck muscle group is still subjected to one-side tension when balancing, lacks static posture balancing and balancing adjustment functions, cannot accurately match the neck action path, and cannot meet the individualized training needs of different training stages and different muscle groups (flexor, extensor, lateral flexor and rotator).

[0004] In addition, the neck muscle training has high requirements for the coordination of the action path and the load direction, and if sufficient degrees of freedom or stable load control cannot be provided, it is easy to cause sports injuries. SUMMARY

[0005] The purpose of the present application is to provide a wearable neck muscle training device, which can be used by wearing, completely uses a mechanical structure to realize the adjustment of training resistance, does not need a power supply or an air supply, and can realize static muscle group training and individualized training of different neck muscle groups.

[0006] The technical scheme adopted by the present application is as follows: A wearable neck muscle training device, comprising a helmet shell for wearing on the head of a human body, a vertical shaft is arranged at the top end of the outside of the helmet shell, and two groups of self-rotation mechanisms that do not interfere with each other are arranged on the vertical shaft; the self-rotation mechanism comprises a cantilever, a weight arranged at the lower end of the cantilever, a retaining frame and a sliding block arranged at the upper end of the cantilever, and a guide ring arranged on the vertical shaft; the retaining frame is rotatably sleeved on the vertical shaft and has an axial movement space; the guide surface at the upper end of the guide ring is inclined to the axial direction of the vertical shaft, and the sliding block is always in contact with the guide surface; when the helmet shell is horizontally static, the sliding block is at the lowest point of the guide surface, and the two groups of self-rotation mechanisms are located at the left and right sides of the vertical shaft and are in a balanced state.

[0007] Preferably, an outer shell is detachably arranged on the outer layer of the helmet shell, the vertical shaft and the two groups of self-rotation mechanisms are arranged in the interlayer between the helmet shell and the outer shell, and the upper end of the vertical shaft is connected with the outer shell.

[0008] Preferably, the top end of the helmet shell is machined with a mounting plane, and the lower end of the vertical shaft is mounted on the mounting plane through a base.

[0009] Preferably, the helmet shell is provided with a binding member for binding the head.

[0010] Preferably, the tilt directions of the guide surfaces of the two groups of spinning mechanisms are opposite to each other.

[0011] Preferably, the cage is distributed with steel balls, and the steel balls are exposed to the inner wall of the cage to form a rolling point contact with the vertical shaft.

[0012] Preferably, the lower end of the sliding block is in contact with the guide surface through a universal ball bearing.

[0013] Preferably, the universal ball bearing comprises a ball seat, a load working ball mounted in the ball seat and partially exposed, and a support lubricating ball group filled between the load working ball and the ball seat.

[0014] Preferably, the upper end of the sliding block is movably connected with the cantilever through a guide structure, and the guide direction of the guide structure is parallel to the axial direction of the vertical shaft.

[0015] Preferably, the counterweight is made of tungsten alloy material.

[0016] The present application has the following beneficial effects: The training device can be used by wearing, and the training resistance is adjusted completely by using a mechanical structure without power supply or gas source, and the static muscle group training and the individualized training of different neck muscle groups can be realized. The guide surface inclined relative to the axial direction of the vertical shaft and the sliding block in contact with the guide surface are key designs. Under the design, when the helmet shell is horizontally static, the sliding block is necessarily at the lowest point of the guide surface, so that the position of the spinning mechanism when the helmet shell is horizontally static can be regulated and controlled, and thus the two groups of spinning mechanisms can be located at the left and right sides of the vertical shaft and in a balanced state when the helmet shell is horizontally static. Therefore, after wearing the helmet shell, the self-adaptive gravity center homing and stabilization of the spinning mechanism can be utilized, so that the static muscle group training can be effectively realized. When slightly inclined to one side, the cantilever will automatically rotate to the low position in the direction of gravity offset, and with the increase of the inclination angle, the lateral pulling force on the inclined side is gradually increased. At the same time, the cooperation of the guide surface and the sliding block can reduce the resistance. In order to maintain stability, the trainer needs to timely adjust the head posture, and the head is pulled in the opposite direction by the neck muscles, so that the individualized training of different neck muscle groups can be effectively realized.

Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] The following detailed description of embodiments of the application in the drawings provided herein is not intended to limit the scope of the application as claimed, but merely represents selected embodiments of the application. Based upon the embodiments herein, all other embodiments obtained by persons of ordinary skill in the art without having to make inventive efforts are within the scope of protection of the application.

[0028] It should be noted that similar reference numbers and letters refer to similar items in the following drawings, and therefore, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0029] The features and performance of the application are further described in detail below in connection with embodiments.

[0030] Embodiment 1 This embodiment discloses a wearable neck muscle trainer, as shown in the accompanying drawings, comprising a helmet shell 20, a vertical shaft 70 and a spinning mechanism; wherein: Figures 1 to 5 The helmet shell 20 is used to be worn on the head of a human body; The vertical shaft 70 is arranged at the outer top end of the helmet shell 20, and two groups of spinning mechanisms are arranged on the vertical shaft 70, which do not interfere with each other, as shown in ; Figures 1 to 4 The spinning mechanism comprises a cantilever 40, a counterweight 30, a retaining frame 60, a sliding block 80 and a guide ring 50, the cantilever 40 extends from above the top end of the helmet shell 20 to the lower part of the helmet shell 20, the counterweight 30 is arranged at the lower end of the cantilever 40, the retaining frame 60 is arranged at the upper end of the cantilever 40, the retaining frame 60 is rotatably fitted on the vertical shaft 70, the retaining frame 60 has an axial movement space, the sliding block 80 is arranged at the upper end of the cantilever 40, and the guide ring 50 is arranged on the vertical shaft 70, the upper end of the guide ring 50 has a guide surface 51, the guide surface 51 is inclined to the axial direction of the vertical shaft 70, and the sliding block 80 is always in contact with the guide surface 51, as shown in ; Figures 1 to 5 When the helmet shell 20 is horizontally stationary, the sliding block 80 is at the lowest point of the guide surface 51, and the two groups of spinning mechanisms are located on the left and right sides of the vertical shaft 70 and are in a balanced state, as shown in Figure 1 and Figure 2 .

[0031] In the above scheme: The vertical shaft 70 serves as a rotation reference for the counterweight 30, the cantilever 40, the retaining frame 60 and the sliding block 80 to rotate around the shaft, and at the same time, transmits the acting force of the spinning mechanism to the helmet shell 20, avoiding local stress concentration; ​The guide surface 51 axially inclined relative to the vertical axis 70 and the slider 80 in contact with the guide surface 51 are key designs, under which the slider 80 is necessarily at the lowest point of the guide surface 51 when the helmet shell 20 is horizontally static, so as to regulate the position of the spin mechanism when the helmet shell 20 is horizontally static, and further to enable the two groups of spin mechanisms to be located at the left and right sides of the vertical axis 70 and in a balanced state when the helmet shell 20 is horizontally static.

[0032] Therefore, the training device has a nonlinear mechanical resistance response characteristic and an adaptive static balance mechanism, and can realize static muscle group training and personalized training of different neck muscle groups (flexor, extensor, lateral flexor, and rotator). After wearing the helmet shell 20, the adaptive gravity homing and stabilization of the spin mechanism can be used to realize static muscle group training when the helmet shell 20 is horizontally static. After wearing the helmet shell 20, when slightly tilting to one side, the cantilever 40 will automatically rotate to the low position in the direction of gravity offset, and as the tilting angle increases, the lateral pulling force on the tilting side gradually increases. At the same time, the cooperation of the guide surface 51 and the slider 80 can reduce the resistance. In order to maintain stability, the trainer needs to adjust the head posture in time, and the neck muscles drive the head to pull in the opposite direction, thereby effectively realizing personalized training of different neck muscle groups (flexor, extensor, lateral flexor, and rotator).

[0033] The training is suitable for different user body types and training intensity requirements, and is suitable for various training scenes such as special occupation physical training, fitness training, body posture correction, sports rehabilitation treatment, and neural rehabilitation treatment, and has good practicality and popularization value.

[0034] Moreover, the training device completely uses a mechanical structure to realize adjustment (maintaining horizontal or adjusting the tilting angle) of training resistance, does not need a power supply or an air source, is reliable to use, is convenient to maintain, and is high in safety. Moreover, the training device can be used after being worn, is convenient to carry for training, and can be arranged in a space such as a gymnasium or a rehabilitation institution.

[0035] In the embodiment, as shown in Figures 1 to 5 The inclination directions of the guide surfaces 51 of the two groups of spin mechanisms are opposite to each other, which can ensure that the two groups of spin mechanisms are located at the left and right sides of the vertical axis 70 when the helmet shell 20 is horizontally static.

[0036] In order to ensure stable installation of the vertical axis 70, in the embodiment, preferably, as shown in Figures 1 to 5 The outer top end of the helmet shell 20 is processed with a mounting plane 21, and the lower end of the vertical axis 70 is mounted on the mounting plane 21 through a base 71.

[0037] In order to adapt to the needs of different head shapes and neck sizes, in the embodiment, preferably, as shown in Figures 1 to 4As shown, the headgear shell 20 is provided with a binding member 10 for binding the head.

[0038] In order to improve the smoothness and accuracy of the movement, and prolong the service life, in the embodiment, preferably: the cage 60 is distributed with steel balls, the steel balls expose the inner wall of the cage 60 and the vertical shaft 70 to form a rolling point contact, which can effectively reduce the friction when the cage 60 rotates; as shown, Figures 1 to 5 As shown, the lower end of the sliding block 80 is in contact with the guide surface 51 through the universal ball bearing 81, which can effectively reduce the friction when the sliding block 80 moves along the guide surface 51; and, as shown, Figure 6 As shown, the universal ball bearing 81 includes a ball seat 81a, a load working ball 81b mounted in the ball seat 81a and partially exposed, and a support lubricating ball group 81c filled between the load working ball 81b and the ball seat 81a.

[0039] In order to keep the sliding block 80 in contact with the guide surface 51, in the embodiment, preferably: as shown, Figures 1 to 5 As shown, the upper end of the sliding block 80 is movably connected with the cantilever 40 through a guide structure, and the guide direction of the guide structure is parallel to the axial direction of the vertical shaft 70.

[0040] In order to save space and avoid interference, in the embodiment, the counterweight 30 is preferably made of tungsten alloy material with high density.

[0041] Embodiment 2 The embodiment discloses another wearable neck muscle trainer, which is different from the embodiment 1 in that: as shown, Figure 7 As shown, the outer layer of the headgear shell 20 is detachably provided with an outer shell 90, the vertical shaft 70 and the two sets of spinning mechanisms are located in the interlayer between the headgear shell 20 and the outer shell 70, and the upper end of the vertical shaft 70 is connected with the outer shell 90. The outer shell 90 can not only play a protective and aesthetic role, but also stabilize the upper end of the vertical shaft 70, so that the vertical shaft 70 has stronger bearing capacity.
