Description

Technical Field

[0001] The present invention belongs to the technical field of head and neck training institutions, and particularly relates to an institution for applying multi-axial acceleration overload impact to the head and neck. Background Art

[0002] Some special sports environments have characteristics of continuous high load, high load growth rate, high angular acceleration, and high cognitive load, such as the training or competition environments where race car drivers are located. Workers in such sports environments generally have symptoms of neck pain. According to domestic investigation reports, the most common change in the physiological curvature of the cervical vertebrae among workers in special sports environments is the change in the physiological curvature of the cervical vertebrae, with an overall incidence rate of 62.5%. The incidences of intervertebral space stenosis, osteophyte formation, and ligament calcification are 28.1%, 34.4%, and 14.5% respectively. With the increase in age, various X-ray pathological changes in the cervical vertebrae increase.

[0003] The main reason for the high incidence of cervical spine diseases among workers working in sports environments with high overload impact on the neck is the acute injury and chronic degeneration of the neck skeletal muscle system caused by the high overload environment in the sports environment. The neck of the human body is mainly supported by two major mechanical support structures. One is the soft tissue composed of neck muscles and ligaments, and the other is the spinal structure composed of vertebral bodies and intervertebral discs. The main function of the spine is to protect the spinal cord and support the body structure to support the movement of the body. When the soft tissue structures that provide support for the spine are fatigued, weakened, or damaged, the spine becomes a passive structure, and the risk of injury increases. Such acute injuries are mainly acute soft tissue injuries caused by the traction of the high overload condition on the neck exceeding the limit that the muscles and ligaments of the cervical vertebrae can withstand. Chronic degeneration is mainly due to the cervical vertebrae being subjected to passive impacts or active intense traction for a long time and multiple times, resulting in an increase in the instantaneous pressure of the cervical intervertebral disc, causing degenerative changes such as disc degeneration or protrusion, or causing hyperplasia, deformation, and change in the physiological curvature of the cervical vertebral body.

[0004] The factors leading to such acute and chronic injuries can be mainly divided into two categories: external factors and internal factors of the body itself. Among them, the high overload environment is the most important external injury-causing factor. And multi-axial acceleration overload impact causes greater harm to the head and neck. The head and neck muscles need to have a certain degree of coordination, endurance, and explosive power to resist the harm brought by multi-axial acceleration overload. At present, the training for acceleration overload impact is not yet mature. In a single training, only acceleration overload impact in one direction can be applied, and multi-axial acceleration overload impact cannot be applied to the head and neck, and the real sports environment cannot be simulated, resulting in poor training effects, so that workers cannot avoid head and neck injuries in the real sports environment even after training. Summary of the Invention

[0005] The present invention is made to solve the above problems, and the purpose is to provide an institution for applying multi-axial acceleration overload impact to the head and neck.

[0006] The present invention provides a mechanism for applying multi-axial acceleration overload impact to the head and neck, which is used to simulate the motion environment in which the user's head and neck are subjected to multi-axial acceleration overload impact. It is characterized in that it includes: a helmet for the user to wear on the head; a horizontal axis loading member arranged on the helmet for applying angular acceleration overload on the horizontal axis; a coronal axis loading member arranged on the horizontal axis loading member for applying angular acceleration overload on the coronal axis; a sagittal axis loading member arranged on the coronal axis loading member for applying angular acceleration overload on the sagittal axis; a tensile force transmission assembly arranged on the sagittal axis loading member for transmitting the tensile force to the sagittal axis loading member, so that the sagittal axis loading member, the coronal axis loading member and the horizontal axis loading member generate angular acceleration.

[0007] The mechanism for applying multi-axial acceleration overload impact to the head and neck provided by the present invention may further have the following technical feature: the horizontal axis loading member is an annular slide rail sleeved on the helmet.

[0008] Furthermore, the mechanism for applying multi-axial acceleration overload impact to the head and neck provided by the present invention may further have the following technical feature: the coronal axis loading member has two linear tracks and an arc track. One ends of the two linear tracks are respectively slidably mounted on the annular slide rail through a first connecting member, the two linear tracks are symmetrically arranged, and two ends of the arc track are respectively connected to the other ends of the two linear tracks.

[0009] Even further, the mechanism for applying multi-axial acceleration overload impact to the head and neck provided by the present invention may further have the following technical feature: the sagittal axis loading member is a long arc track, the corresponding circumferential diameter of which is larger than that of the arc track, and the sagittal axis loading member is slidably mounted on the arc track through a second connecting member.

[0010] Even further, the mechanism for applying multi-axial acceleration overload impact to the head and neck provided by the present invention may further have the following technical feature: the tensile force transmission assembly has a traction ring and a traction rope. The traction ring is fixed at one end of the long arc track, and one end of the traction rope is fixed on the traction ring.

[0011] Functions and effects of the invention

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the following embodiments will specifically elaborate on the mechanism for applying multi-axial acceleration overload impact to the head and neck of the present invention in conjunction with the drawings.

[0018] <Embodiment>

[0019] This embodiment will elaborate in detail on the specific structure and usage method of the mechanism for applying multi-axial acceleration overload impact to the head and neck (hereinafter referred to as the overload impact mechanism).

[0020] In this embodiment, the up, down, left, right, front and back of the user are defined as the upper, lower, left, right, front and rear directions.

[0021] Figure 1 is a schematic structural diagram of the overload impact mechanism in the embodiment of the present invention,Figure 2 This is a schematic structural view of the overload impact mechanism after omitting the helmet and the towing rope in the embodiment of the present invention.

[0022] As Figure 1 and Figure 2 shown, the mechanism 100 for applying multi-axial acceleration overload impact to the head and neck (hereinafter referred to as mechanism 100) includes a helmet 10, a horizontal axis loading member 20, a coronal axis loading member 30, a sagittal axis loading member 40, and a tension transmission assembly 50.

[0023] The helmet 10 is for the user to wear on the head.

[0024] The horizontal axis loading member 20 is an annular slide rail, sleeved and fixed on the helmet 10, and the plane corresponding to its annular shape is a horizontal plane, or has a slight angle with the horizontal plane.

[0025] The coronal axis loading member 30 has two linear tracks 31, an arc track 32, and a first connecting member 33.

[0026] Figure 3 This is a cross-sectional view of the connection structure between the first connecting member and the horizontal axis loading member in the embodiment of the present invention.

[0027] One end of the two linear tracks 31 is installed on the horizontal axis loading member 20 through the first connecting member 33, and the two linear tracks are symmetrically arranged.

[0028] As Figure 2 , 3 shown, the horizontal axis loading member 20 has an outer ring 21, an inner ring 22, and a connecting ring 23. Among them, the outer ring 21 is in an annular strip shape, located outside the inner ring 22 and its diameter is slightly larger than that of the inner ring 22; the inner ring 22 is fixedly sleeved on the helmet 10; the connecting ring 23 is connected between the two, so that the cross-section of the horizontal axis loading member 20 (i.e., the cross-section perpendicular to its length direction) is in an I-shape. In addition, in this embodiment, the widths of the outer ring 21 and the inner ring 22 are the same.

[0029] A groove is formed on the first connecting member 33, and the cross-section of the groove matches that of the outer ring 21, so it can be sleeved on the outer ring 21 and move along the length direction (i.e., the circumferential direction) of the horizontal axis loading member 20. In addition, a through hole is provided on the first connecting member 33, and after the bolt 60 passes through the through hole, it abuts against the surface of the connecting ring 23, so that the first connecting member 33 is fixed on the horizontal axis loading member 20 and cannot move. After removing the bolt 60, the first connecting member 33 can slide on the horizontal axis loading member 20.

[0030] As Figure 2 shown, one end of the linear track 31 is connected to the side of the first connecting member 33 opposite to the through hole (the upper side during actual use), and can slide along with the first connecting member 33.

[0031] The two ends of the arc track 32 are respectively fixed to the other ends of the two linear tracks 31, so that the arc track 32 and the linear track 31 are integrated. Therefore, the arc track 32 and the linear track 31 can move together. In this embodiment, the circumference surface corresponding to the arc track 32 is perpendicular to the circumference surface corresponding to the horizontal axis loading member 20. Therefore, through the first connecting member 33, the crown axis loading member 30 can be rotated as a whole with the axis passing through the center of the horizontal axis loading member 20 and perpendicular to the horizontal axis loading member 20 as the center line, and its direction is Figure 2 The D1 direction in the

[0032] The sagittal axis loading member 40 is a long arc track, and the corresponding circumferential diameter thereof is larger than the circumferential diameter corresponding to the arc track 32 . The sagittal axis loading member 40 is detachably fixed to the middle part of the arc track 32 via a second connecting member 41 .

[0033] Figure 4 It is a partial enlarged structural diagram of the second connecting piece.

[0034] like Figure 2 , 4 As shown, the structures of the arc track 32 and the sagittal axis loading member 40 are the same as those of the horizontal axis loading member 20, and the cross-sections are both I-shaped. The second connecting member 41 is in the shape of a cube as a whole, and its bottom surface is provided with a first groove 41a that matches the arc track 32, and its top surface is provided with a second groove 41b that matches the sagittal axis loading member 40, and the directions of the first groove 41a and the second groove 41b are perpendicular to each other. As a result, the sagittal axis loading member 40 can move as a whole along the length direction of the arc track 32 (i.e. Figure 2 The D2 direction in the figure), it can also slide forward and backward along its own length direction (i.e. Figure 2 In addition, similar to the first connecting member 33, the second connecting member 41 is provided with two through holes perpendicular to each other. After the two bolts 60 are inserted into the two through holes, they abut against the arc track 32 and the sagittal axis loading member 40, so that the arc track 32 and the sagittal axis loading member 40 cannot move relative to each other when the bolts 60 are not removed; after being removed, the two can move relative to each other.

[0035] like Figure 1 , Figure 2As shown, the tensile force transmission assembly 50 has a traction ring 51 and a traction rope 52. The traction ring 51 is fixed to one end of the sagittal axis loading member 40, and one end of the traction rope 52 is fixed to the traction ring 51. When an external force conducts tensile force to the traction ring 51 through the traction rope 52, this external force can form different component forces through the relative movements of the horizontal axis loading member 20, the coronal axis loading member 30, and the sagittal axis loading member 40 in the D1, D2, and D3 directions, so as to apply a multi-axial acceleration overload impact to the head and neck through the helmet 10.

Moreover, by adjusting the positional relationship between the horizontal axis loading member, the coronal axis loading member, and the sagittal axis loading member, acceleration overload impacts at various angles can be applied, simulating the real motion environment to the greatest extent and achieving a better training effect. Therefore, the mechanism for applying a multi-axial acceleration overload impact to the head and neck in this embodiment can apply a multi-axial acceleration overload impact to the head and neck, simulate the real motion environment, improve the training effect, and prevent the trained staff from being injured in the real motion environment.
