[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] 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.

[0028] Example 1

[0029] Reference Figure 1-Figure 6 , which is the first embodiment of the utility model, and provides a protective device for a car shock absorber block. The protective device for a car shock absorber block includes a shock absorbing component 100 and a disassembly component, which cooperate to effectively disassemble the dust cover 106.

[0030] Specifically, the shock absorbing assembly 100 includes a damper 101, a spring disk 102, a lower spring pad 103, a first spring 104, a shock absorbing block 105, a dust cover 106 and an upper spring pad 107. The spring disk 102 is fixed to the outside of the damper 101, the lower spring pad 103 is fixed in the spring disk 102, the first spring 104 is fixed to the top of the lower spring pad 103, the shock absorbing block 105 is arranged on the outside of the damper 101, the dust cover 106 is located on the outside of the shock absorbing block 105, and the upper spring pad 107 is fixed to the top of the first spring 104.

[0031] A piston and liquid (not shown in the figure) are arranged inside the damper 101. The two ends of the first spring 104 are fixed to the lower spring pad 103 and the upper spring pad 107 respectively. When impacted by external force, the damper 101 will expand and contract rapidly, and at the same time, the upper spring pad 107 will be driven to expand and contract rapidly, thereby driving the first spring 104 to expand and contract rapidly. The shock absorbing block 105 and the dust cover 106 will also move relatively to each other, thereby playing a buffering role for the damper 101.

[0032] One side of the dust cover 106 is open. When installing the dust cover 106, the dust cover 106 is passed through the first spring 104 and is sleeved on the outside of the shock-absorbing block 105. At this time, the opening positions of the dust cover 106 are overlapped together, so that the dust cover 106 can be combined into a ring and the shock-absorbing block 105 is protected inside. When the dust cover 106 needs to be disassembled, it is only necessary to separate the overlapping positions of the dust cover 106. At this time, the dust cover 106 can be removed from the outside of the shock-absorbing block 105, which makes it easy to replace the dust cover 106, thereby reducing maintenance costs and difficulty.

[0033] The specific disassembly component 200 is arranged on one side of the dust cover 106, and includes a support member 201, a force-bearing member 202, an extrusion member 203 and a limiting member 204. The force-bearing member 202 is arranged on one side of the dust cover 106, and the extrusion member 203 is located in the force-bearing member 202. The support member 201 is arranged on one side of the dust cover 106, and the limiting member 204 is arranged in the force-bearing member 202.

[0034] The overlapping position of the dust cover 106 is clamped and fixed by the force-bearing member 202, so as to fix the dust cover 106 and prevent it from falling off after installation. The force-bearing member 202 can be effectively supported by the setting of the support member 201 to prevent it from deflecting.

[0035] When the upper spring pad 107 moves downward due to the vibration of the car, it will drive the extrusion piece 203 to move downward, and apply a thrust to the force-bearing piece 202 through the extrusion piece 203, so that the force-bearing piece 202 applies a greater extrusion force to the dust cover 106, thereby improving the fixing effect of the dust cover 106, thereby preventing the dust cover 106 from falling off when the car vibrates. The force-bearing piece 202 can be restricted by the setting of the limit piece 204, thereby preventing the force-bearing piece 202 from deviating during the driving of the car and causing the dust cover 106 to fall off.

[0036] Example 2

[0037] Reference Figure 1-Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0038] Specifically, the support member 201 includes a first fixed column 201 a and a movable column 201 b , the first fixed column 201 a is fixed on the lower spring pad 103 , and the movable column 201 b is located on one side of the first fixed column 201 a .

[0039] The movable column 201b is inserted into the first fixed column 201a and movably connected with the first fixed column 201a. The top of the movable column 201b is fixed to the upper spring pad 107. The movable column 201b can improve the stability of the first fixed column 201a and avoid the first fixed column 201a from deviating. When the upper spring pad 107 moves downward due to the vibration of the car, it will drive the movable column 201b to move into the first fixed column 201a, and will not hinder the movement of the upper spring pad 107.

[0040] Specifically, the force-bearing member 202 includes a force-bearing rod 202a, a force-bearing plate 202b and a movable rod 202c. The force-bearing rod 202a is arranged on one side of the dust cover 106, the force-bearing plate 202b is located on one side of the force-bearing rod 202a, and the movable rod 202c is arranged on one side of the force-bearing rod 202a.

[0041] One side of the force-bearing plate 202b is hinged to the first fixed column 201a through a hinge plate, and the movable rod 202c is movably connected to the force-bearing rod 202a, and one side of the force-bearing rod 202a is in an open state.

[0042] When the dust cover 106 is installed and the opening position coincides, the force-bearing plate 202b drives the force-bearing rod 202a and the movable rod 202c to move, so that the force-bearing rod 202a and the movable rod 202c contact the dust cover 106, and the position of the opening connection of the dust cover 106 is clamped and fixed, so that the dust cover 106 can be fixed, thereby preventing the dust cover 106 from falling off during use.

[0043] When the upper spring pad 107 moves downward, if it contacts the dust cover 106 , it will push the movable rod 202 c to move downward, thereby avoiding obstruction to the movement of the upper spring pad 107 .

[0044] Specifically, there are two force-bearing plates 202b, which are respectively located on both sides of the first fixing column 201a.

[0045] The force-bearing plate 202b drives the force-bearing rod 202a and the movable rod 202c to move, so that the force-bearing rod 202a and the movable rod 202c contact the dust cover 106, and clamp and fix the position of the opening connection of the dust cover 106, so as to fix the dust cover 106, thereby preventing the dust cover 106 from falling off during use.

[0046] Specifically, the force-bearing member 202 further includes a second spring 202d, and two ends of the second spring 202d are respectively fixed to the force-bearing rod 202a and the movable rod 202c.

[0047] When the upper spring pad 107 is reset, the second spring 202d applies an upward thrust to the movable rod 202c, so that the movable rod 202c moves to the initial position, thereby continuing to clamp and fix the dust cover 106.

[0048] Specifically, the force-bearing member 202 further includes a third spring 202e, and two ends of the third spring 202e are respectively fixed to the two force-bearing plates 202b.

[0049] The third spring 202e is located between the first fixed column 201a and the force-bearing rod 202a. The third spring 202e is used to apply tension to the two force-bearing plates 202b, so that the two force-bearing plates 202b can move toward each other and drive the force-bearing rod 202a and the movable rod 202c to move, so that the two can clamp and fix the dust cover 106.

[0050] Example 3

[0051] Reference Figure 1-Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0052] Specifically, the extrusion member 203 includes an extrusion block 203a, an extrusion plate 203b, a second fixed column 203c and a third fixed column 203d. The extrusion block 203a is fixed to the bottom of the upper spring pad 107, the extrusion plate 203b is located in the force-bearing plate 202b, the second fixed column 203c is arranged in the extrusion plate 203b, and the two ends of the third fixed column 203d are respectively fixed to the second fixed column 203c and the first fixed column 201a.

[0053] There are two extrusion plates 203b, which are located on both sides of the extrusion block 203a respectively. The side of the extrusion plate 203b close to the extrusion block 203a is inclined. The second fixed column 203c is movably connected with the two extrusion plates 203b to position the two to avoid their displacement during movement. The third fixed column 203d is used to support and fix the second fixed column 203c.

[0054] When the upper spring pad 107 moves downward, it will also drive the extrusion block 203a to move downward. At this time, the bottom end of the extrusion block 203a will squeeze the inclined surface of the extrusion plate 203b, thereby pushing the extrusion plate 203b to move, and through the extrusion plate 203b, push one side of the force-bearing plate 202b to move outward. At this time, the other side of the force-bearing plate 202b will move inward, thereby enabling it to drive the force-bearing rod 202a and the movable rod 202c to move, so that the two can increase the fastening of the dust cover 106, thereby preventing the dust cover 106 from falling off when it is vibrated.

[0055] Specifically, the extrusion member 203 further includes a fixing block 203e and a fourth fixing column 203f. The fixing block 203e is fixed to one side of the first fixing column 201a, and one end of the fourth fixing column 203f is fixed to the fixing block 203e.

[0056] There are two fourth fixing columns 203f, which are respectively located on both sides of the fixing block 203e. The fourth fixing columns 203f are movably connected to the extrusion plate 203b to position the extrusion plate 203b to prevent it from shifting during movement.

[0057] Specifically, the extrusion member 203 further includes a fourth spring 203g, both ends of which are fixed to the fixing block 203e and the extrusion plate 203b respectively, and are sleeved on the outer side of the fourth fixing column 203f.

[0058] There are two fourth springs 203g, which are respectively sleeved on the outside of the two fourth fixing columns 203f. Through the setting of the fourth spring 203g, when the extrusion plate 203b is in the initial state, it is used to position it to prevent the extrusion plate 203b from moving at will. When the extrusion plate 203b moves, the fourth spring 203g will be stretched. When the extrusion block 203a is separated from the extrusion plate 203b, the fourth spring 203g can apply a pulling force to the extrusion plate 203b, so that the extrusion plate 203b can be reset.

[0059] Specifically, the limiting member 204 includes a limiting block 204a, which is fixed to one side of the movable rod 202c. A limiting groove 202a-1 is provided on the force-bearing rod 202a, and the limiting block 204a slides in the limiting groove 202a-1.

[0060] When the movable rod 202c moves, it drives the limiting block 204a to slide in the limiting groove 202a-1. When the movable rod 202c stops sliding, the limiting block 204a also stops sliding, thereby preventing the movable rod 202c from shifting in position.

[0061] When in use, when it is necessary to install the dust cover 106, the dust cover 106 is passed through the first spring 104 and is sleeved on the outside of the shock absorbing block 105. The end of the force plate 202b with a larger opening is pressed by hand to apply tension to it, so that the two force plates 202b can move toward the side close to each other, so that the force rod 202a and the movable rod 202c are separated from the overlapping position of the dust cover 106. At this time, the opening position of the dust cover 106 is overlapped together, so that the dust cover 106 can be It is combined into a ring shape and the shock-absorbing block 105 is protected inside. Then, when the dust cover 106 is installed and the opening position coincides, the force-bearing rod 202a and the movable rod 202c are driven to move through the force-bearing plate 202b, so that the force-bearing rod 202a and the movable rod 202c are in contact with the dust cover 106, and the position of the opening connection of the dust cover 106 is clamped and fixed, so that the dust cover 106 can be fixed, thereby preventing the dust cover 106 from falling off during use.

[0062] When the car is driving, when the upper spring pad 107 moves downward, it will also drive the extrusion block 203a to move downward. At this time, the bottom end of the extrusion block 203a will squeeze the inclined surface of the extrusion plate 203b, thereby pushing the extrusion plate 203b to move, and through the extrusion plate 203b, push one side of the force-bearing plate 202b to move outward. At this time, the other side of the force-bearing plate 202b will move inward, thereby enabling it to drive the force-bearing rod 202a and the movable rod 202c to move, so that the two can increase the fastening of the dust cover 106, thereby preventing the dust cover 106 from falling off when it is vibrated.

[0063] When the dust cover 106 needs to be removed, press the end of the force-bearing plate 202b with the larger opening by hand and apply pulling force to it, so that the two force-bearing plates 202b can move toward the closer side, so as to drive the force-bearing rod 202a and the movable rod 202c to separate from the overlapping position of the dust cover 106, and then separate the overlapping position of the dust cover 106. At this time, the dust cover 106 can be removed from the outside of the shock-absorbing block 105, so that the dust cover 106 can be easily replaced.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
