Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides a cartilage impact injury modeling device, which includes a main body component 100, a convergence component 200 and a limit component 300. The three can cooperate to accurately control the size of the impact force and simulate different degrees of cartilage contusion.

[0029] The bunching assembly 200 includes a bunching member 201, including a moving plate 201a, a gear ring 201b, a support plate 201c and a rack 201d. The gear ring 201b is sleeved on the outer side of the moving plate 201a. There are four moving plates 201a. The moving plate 201a is located on the inner wall of the gear ring 201b and meshedly connected. A tooth groove 201b-1 is provided on the outer side of the gear ring 201b. The support plate 201c is provided at one end of the gear ring 201b. The support plate 201c is connected to the moving plate 201a through a rotating shaft. The rack 201d is provided on one side of the tooth groove 201b-1 and meshedly connected.

[0030] The outer cover of the support plate 201c is provided with a protective cover.

[0031] The support plate 201c is used to support the ring gear 201b. By moving the rack 201d, the rack 201d moves and engages with the tooth groove 201b-1. The tooth groove 201b-1 drives the ring gear 201b to rotate. The ring gear 201b rotates and engages with the moving plate 201a to open and close the moving plate 201a.

[0032] The limiting assembly 300 is arranged on one side of the supporting plate 201c, and includes a limiting member 301, including a first fixed plate 301a, a hinge block 301b, a first extrusion block 301c and a first extrusion plate 301d. The hinge block 301b is hinged on the inner wall of the first fixed plate 301a, the first fixed plate 301a is sleeved on the outside of the hinge block 301b, the first extrusion block 301c is arranged on one side of the hinge block 301b, and the first extrusion plate 301d is arranged on one side of the first extrusion block 301c.

[0033] By squeezing the first squeezing plate 301d, the first squeezing plate 301d moves and drives the first squeezing block 301c to move to the side of the first fixed plate 301a, so that the pressing ball 103 can be limited and the pressing ball 103 can be moved to a specified position. When the pressing ball 103 returns to its original position, the second squeezing block 302b squeezes the hinge block 301b to flip the hinge block 301b. At this time, the second squeezing block 302b will not limit the first fixed plate 301a, so that the pressing ball 103 can move normally.

[0034] A baffle is provided on one side of the first fixed plate 301a, which can limit the hinge block 301b so that the hinge block 301b can only be flipped to one side. A torsion spring is provided on one side of the hinge block 301b, and one end of the torsion spring is fixed to one side of the first fixed plate 301a. When the hinge block 301b is flipped, the torsion spring can be squeezed. When the second squeezing block 302b is separated from the hinge block 301b, the hinge block 301b can return to its original position through the rebound of the torsion spring.

[0035] Example 2

[0036] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0037] Specifically, four sliders 202a are provided at one end of the rack 201d, a rotating disk 202b is sleeved on the outer side of the slider 202a, a sliding groove 202b-1 is opened on the inner wall of the rotating disk 202b, and the four sliders 202a are located on the inner wall of the sliding groove 202b-1 and slide.

[0038] The rotating disk 202b is used to support the four sliders 202a. By moving the rack 201d, the rack 201d moves and engages with the tooth groove 201b-1. The tooth groove 201b-1 drives the ring gear 201b to rotate. The rotation of the ring gear 201b drives the slider 202a to slide on the inner wall of the slide groove 202b-1 through the guidance of the slide groove 202b-1. The movable plate 201a is engaged by the rotation of the ring gear 201b to open and close.

[0039] Specifically, a connecting rod 202c is provided at one end of the rack 201d, a supporting frame 202d is provided at the top of the connecting rod 202c, and three supporting grooves 202d-1 are provided on the inner wall of the supporting frame 202d.

[0040] The connecting rod 202c is used to support the rack 201d, and the supporting frame 202d is used to support the first extrusion rod 202e. By extruding the connecting rod 202c, the connecting rod 202c moves and drives the rack 201d to move.

[0041] The supporting frame 202d is covered with a protective shell.

[0042] Specifically, a first extrusion rod 202e is inserted into the top of the support frame 202d, a first pressing shaft 202f is arranged at the bottom of the first extrusion rod 202e, a first spring 202g is arranged on the outer sleeve of the first pressing shaft 202f, one end of the first spring 202g is fixed to the bottom of the first extrusion rod 202e, and the other end is fixed to the top of the support frame 202d, a first movable shaft 202h is inserted into the inner wall of the first extrusion rod 202e, and the other end of the first movable shaft 202h is arranged at one end of the first extrusion plate 301d.

[0043] The first movable shaft 202h is located on the inner wall of the supporting groove 202d-1 and slides.

[0044] By squeezing the first squeezing rod 202e, the first squeezing rod 202e squeezes the first pressing shaft 202f, and the first squeezing rod 202e also squeezes the first spring 202g. When the first squeezing rod 202e moves, it will drive the first movable shaft 202h to move on the inner wall of the support groove 202d-1. The first movable shaft 202h squeezes the first squeezing plate 301d. The movement of the first squeezing plate 301d drives the first squeezing block 301c to move to the side of the first fixed plate 301a. When the first pressing shaft 202f is pressed down, it squeezes the connecting rod 202c. The movement of the connecting rod 202c can converge the movable plate 201a, thereby controlling the rebound force of the movable plate 201a. When the first squeezing rod 202e needs to return to its original position, the rebound of the first spring 202g can drive the movable plate 201a to return to its original position.

[0045] Specifically, a second extrusion rod 202i is provided on one side of the first extrusion rod 202e, a second pressing shaft 202j is provided at the bottom of the second extrusion rod 202i, a second spring 202k is provided on the outer sleeve of the second pressing shaft 202j, one end of the second spring 202k is fixed to the bottom of the second extrusion rod 202i, and the other end is fixed to the top of the support frame 202d, and a second movable shaft 202l is inserted into the inner wall of the second extrusion rod 202i.

[0046] The second movable shaft 2021 is located on the inner wall of the supporting groove 202d-1 and slides.

[0047] When the second extrusion rod 202i is pressed, the second pressing shaft 202j will be pressed down, and the second extrusion rod 202i can squeeze the second spring 202k when it moves. By pressing down the second pressing shaft 202j, the connecting rod 202c will be squeezed. The movement of the connecting rod 202c can converge the movable plate 201a, thereby controlling the rebound force of the movable plate 201a. When the second extrusion rod 202i needs to return to its original position, the rebound of the second spring 202k can drive the movable plate 201a to return to its original position. When the second extrusion rod 202i moves, the second movable shaft 202l will be driven to slide on the inner wall of the support groove 202d-1, thereby supporting the second extrusion rod 202i.

[0048] The first pressing shaft 202f and the second pressing shaft 202j have different lengths. By moving different pressing shafts, the connecting rod 202c can be squeezed to different degrees, so that the connecting rod 202c can be moved to different heights, thereby adjusting the convergence of the moving plate 201a and further adjusting the rebound force of the moving plate 201a.

[0049] Specifically, a third extrusion rod 202m is arranged on one side of the second extrusion rod 202i, a third pressing rod 202n is arranged at the bottom of the third extrusion rod 202m, a third spring 202o is arranged on the outer sleeve of the third pressing rod 202n, one end of the third spring 202o is fixed to the bottom of the third extrusion rod 202m, and the other end is fixed to the top of the support frame 202d, and a third movable shaft 202p is inserted into the inner wall of the third extrusion rod 202m.

[0050] The third movable shaft 202p is located on the inner wall of the supporting groove 202d-1 and slides.

[0051] When it is necessary to return the first movable axis 202h or the second movable axis 202l to its original position, the third extrusion rod 202m is squeezed, and the third extrusion rod 202m squeezes the third pressing rod 202n, and the third extrusion rod 202m squeezes the third spring 202o. The third extrusion rod 202m moves to drive the third movable axis 202p to slide on the inner wall of the support groove 202d-1. The first movable axis 202h or the second movable axis 202l can be reset by the sliding of the third movable axis 202p. When it is necessary to return the third extrusion rod 202m to its original position, the third spring 202o can be reset by the rebound of the third spring 202o.

[0052] Example 3

[0053] Reference Figure 5-Figure 6 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0054] Specifically, a driving plate 202q is provided on one side of the support frame 202d, and a first moving groove 202q-1 is provided on the inner wall of the driving plate 202q, a second moving groove 202q-2 is provided on one side of the first moving groove 202q-1, and a third moving groove 202q-3 is provided on one side of the second moving groove 202q-2. The first moving axis 202h is located on the inner wall of the first moving groove 202q-1 and slides, the second moving axis 202l is located on the inner wall of the second moving groove 202q-2 and slides, and the third moving axis 202p is located on the inner wall of the third moving groove 202q-3 and slides. A support bar 202r is provided at the bottom of the support frame 202d, and a connecting bar 202s is provided at the bottom of the driving plate 202q. A fourth spring 202t is fixed to one side of the support bar 202r, and the other end of the fourth spring 202t is fixed to one end of the connecting bar 202s.

[0055] By pressing the first extrusion rod 202e, the first movable shaft 202h can be driven to slide and engage on the inner wall of the first movable groove 202q-1. By pressing the second movable shaft 202l, the second movable shaft 202l can be driven to slide and engage on the inner wall of the second movable groove 202q-2. When it is necessary to return the first movable shaft 202h or the second movable shaft 202l to its original position, by squeezing the third extrusion rod 202m, the third extrusion rod 202m drives the third movable shaft 202p to slide on the inner wall of the third movable groove 202q-3. At this time, the third movable shaft 202p will drive the driving plate 202q to move. The movement of the driving plate 202q drives the connecting strip 202s to pull the fourth spring 202t. By moving the driving plate 202q, the corresponding movable grooves of the first movable shaft 202h or the second movable shaft 202l can be separated, so that the first movable shaft 202h or the second movable shaft 202l can be reset.

[0056] Specifically, a second extrusion block 302b is provided on one side of the first fixed plate 301a, a first extrusion bar 302c is provided on one end of the second extrusion block 302b, a second extrusion plate 302d is provided on one end of the first extrusion bar 302c, a second movable axis 202l is provided on the other end of the second extrusion plate 302d, a first fixed bar 302e is sleeved on the outside of the first extrusion bar 302c, a fifth spring 302f is fixed on one end of the first fixed bar 302e, and the other end of the fifth spring 302f is fixed to one end of the second extrusion plate 302d.

[0057] The second extrusion plate 302d is extruded by the second movable shaft 2021, and the movement of the second extrusion plate 302d drives the first fixed bar 302e to move. When the first extrusion bar 302c moves, it will move on the first fixed bar 302e. When moving on the first fixed bar 302e, the fifth spring 302f can be squeezed, and the first fixed bar 302e can drive the second extrusion block 302b to move. When the second extrusion block 302b needs to be returned to its original position, the rebound of the fifth spring 302f can drive the second extrusion block 302b to return to its original position.

[0058] Specifically, a second extrusion bar 302g is provided at one end of the first extrusion block 301c, and the other end of the second extrusion bar 302g is provided at one end of the first extrusion plate 301d. A second fixing bar 302h is provided on the outer sleeve of the second extrusion bar 302g, and a sixth spring 302i is fixed at one end of the second fixing bar 302h, and the other end of the sixth spring 302i is fixed to one end of the first extrusion plate 301d.

[0059] The first extrusion plate 301d is extruded by the first movable axis 202h, and the movement of the first extrusion plate 301d drives the second extrusion bar 302g to move. The second extrusion bar 302g moves on the second fixed bar 302h. When the second fixed bar 302h moves, the sixth spring 302i is squeezed, and the second fixed bar 302h can drive the first extrusion block 301c to move. When the first extrusion block 301c needs to be returned to its original position, the first extrusion block 301c can be driven to return to its original position by the rebound of the sixth spring 302i.

[0060] Specifically, it also includes a main body component 100, including a supporting shell 101, a pushing shaft 102, a pressing ball 103, a seventh spring 104 and a pulling block 105. The pushing shaft 102 is inserted into the inner wall of the supporting shell 101, the supporting shell 101 is sleeved on the outside of the pushing shaft 102, the pressing ball 103 is arranged at one end of the pushing shaft 102, one end of the seventh spring 104 is fixed to one end of the pushing shaft 102, and the other end is fixed to the inner wall of the supporting shell 101, and the pulling block 105 is fixed to the other end of the pushing shaft 102.

[0061] One end of the first fixing bar 302e and one end of the second fixing bar 302h are fixed to the inner wall of the supporting shell 101 .

[0062] One end of the first fixing plate 301 a is fixed on the driving shaft 102 .

[0063] When the cartilage impact needs to be tested, the pulling block 105 is pulled, and the pulling block 105 drives the pushing shaft 102 to move. When the pushing shaft 102 moves, the seventh spring 104 can be squeezed, and then the pulling block 105 is released. The rebound of the seventh spring 104 drives the pulling block 105 to rebound. The rebound of the pulling block 105 drives the pressing ball 103 to move. The cartilage impact can be tested by the movement of the pressing ball 103. The support shell 101 is used to support the pushing shaft 102.

[0064] During use, when it is necessary to test the cartilage impact, the first extrusion rod 202e is pressed, and the first extrusion rod 202e squeezes the first pressing axis 202f. When the first extrusion rod 202e moves, it will drive the first movable axis 202h to slide on the inner wall of the support groove 202d-1 until it is engaged with the support groove 202d-1. The movement of the first movable axis 202h will drive the driving plate 202q to move. The movement of the driving plate 202q drives the connecting bar 202s to pull the fourth spring 202t. When the first movable axis 202h moves, the first extrusion plate 301d is squeezed. The movement of the first extrusion plate 301d drives the second extrusion bar 302g to move. The second extrusion bar 302g moves and moves on the second fixed bar 302h. When the second fixed bar 302h moves, the sixth spring 302i is squeezed. 302h can drive the first extrusion block 301c to move. When the first extrusion block 301c moves to the side of the first fixed plate 301a, the pressing ball 103 can be limited. By pulling the pulling block 105, the pulling block 105 drives the pushing shaft 102 to move. When the pushing shaft 102 moves, the seventh spring 104 can be squeezed. Then the pulling block 105 is released. The rebound of the seventh spring 104 drives the pulling block 105 to rebound. The rebound of the pulling block 105 drives the pressing ball 103 to move. The cartilage impact can be tested by the movement of the pressing ball 103. Then, when the pressing ball 103 returns to its original position, the second extrusion block 302b will squeeze the hinge block 301b to flip the hinge block 301b. At this time, the second extrusion block 302b will not limit the first fixed plate 301a, so that the pressing ball 103 can move normally.

[0065] When the first squeezing rod 202e moves, it squeezes the first spring 202g, so that the first pressing shaft 202f squeezes the connecting rod 202c. The connecting rod 202c moves and drives the rack 201d to engage with the tooth groove 201b-1 and rotate. The ring gear 201b rotates and engages with the movable plate 201a. The rotation of the ring gear 201b drives the slider 202a to slide on the inner wall of the slide groove 202b-1 through the guidance of the slide groove 202b-1. The rotation of the slider 202a drives the movable plate 201a to rotate. The rotation of the movable plate 201a can clamp the driving shaft 102 When the first extrusion rod 202e needs to be returned to its original position, the third extrusion rod 202m is squeezed, and the third extrusion rod 202m squeezes the third pressing rod 202n, and the third extrusion rod 202m squeezes the third spring 202o. The third extrusion rod 202m moves to drive the third movable shaft 202p to slide on the inner wall of the support groove 202d-1, and the third movable shaft 202p moves to drive the driving plate 202q to move. After the driving plate 202q moves to separate from the first movable shaft 202h, the first extrusion rod 202e can be returned to its original position.
