[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] In the description of the present invention, it should be clarified that the terms "vertical", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal" and the like indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not mean that the device or element referred to must have a specific orientation or position, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The embodiment of the present invention provides a shock absorber 1, such as Figure 1 and Figure 4As shown, the shock absorber 1 is used to connect the vehicle-mounted device body 2 and the vehicle body 3, for example, the shock absorber 1 is located between the vehicle-mounted device body 2 and the vehicle body 3. The vehicle-mounted device body 2 is, for example, a frequency jammer or other types of equipment. The vehicle-mounted device body 2 can be installed on the top of the vehicle body 3.

[0025] The shock absorber 1 includes a base 11, a cover 12, and an elastic member 13. The base 11 is used to connect to the vehicle body 3. The cover 12 is used to connect to the vehicle-mounted device body 2, and a sliding structure is provided between the cover 12 and the base 11, and the sliding structure enables the cover 12 to slide back and forth relative to the base 11. The elastic member 13 connects the base 11 and the cover 12, and when the cover 12 slides toward the base 11, the elastic member 13 is compressed.

[0026] In this embodiment, the shock absorber 1 absorbs the force transmitted from the vehicle body 3 to the vehicle-mounted equipment body 2 (for example, when the vehicle body 3 brakes, accelerates, turns, or the road is bumpy, the vehicle body 3 and the vehicle-mounted equipment body 2 will have a relative movement tendency to squeeze the shock absorber 1 arranged between the vehicle body 3 and the vehicle-mounted equipment body 2, and the shock absorber 1 squeezes the elastic member 13 through the relative sliding of the cover body 12 and the base 11, and the elastic member 13 deforms to absorb the squeezing force) to reduce the amplitude of the shaking of the vehicle-mounted equipment body 2, or even avoid the shaking of the vehicle-mounted equipment body 2, thereby ensuring that the vehicle-mounted equipment body 2 can operate stably.

[0027] Among them, since the elastic member 13 is provided, the cover body 12 can slide relative to the base 11 when the elastic member 13 and the cover body 12 are subjected to external force. The sliding structure limits the relative sliding direction of the base 11 and the cover body 12, and the sliding direction is parallel to the elastic force direction of the elastic member 13. By reasonably setting the sliding direction of the sliding structure and the installation posture of the elastic member 13, the force applied by the vehicle body 3 and the vehicle-mounted device body 2 to the shock absorber 1 in a specific direction can be absorbed, thereby reducing the shaking of the vehicle-mounted device body 2 in a specific direction. For example: if it is necessary to buffer the force in the driving direction of the vehicle, the sliding direction of the sliding structure and the elastic force direction of the elastic member 13 must at least have a component parallel to the driving direction of the vehicle.

[0028] The elastic member 13 may be made of silicone, rubber or other elastic material, and can play a buffering role.

[0029] In the specific implementation process of this embodiment 1, Figures 1 to 4 As shown, the cover 12 can slide back and forth along the first axis a relative to the base 11, wherein the projection a1 of the first axis a on the horizontal plane is parallel to the projection of the axis of the front-rear direction of the vehicle body 3 on the horizontal plane or intersects at an angle less than 90 degrees.

[0030] It can be understood that the front-to-back direction of the vehicle body 3 is parallel to the vehicle travel direction. If the projection a1 of the first axis a on the horizontal plane is parallel to the projection of the axis of the front-to-back direction of the vehicle body 3 on the horizontal plane (e.g. Figure 4 As shown), that is, the relative sliding direction of the base 11 and the cover 12 has a component in the front-to-back direction of the vehicle body 3, so that the force generated by the vehicle body 3 on the shock absorber 1 when it moves forward or backward can be absorbed, so that the force acting on the vehicle-mounted device body 2 when the vehicle moves forward or backward can be buffered. Or if the projection a1 of the first axis a on the horizontal plane intersects with the projection of the axis of the front-to-back direction of the vehicle body 3 on the horizontal plane at an angle less than 90 degrees (not shown in the figure), that is, the relative sliding direction of the base 11 and the cover 12 is inclined left and right with the front-to-back direction of the vehicle body 3, so that the relative sliding direction of the base 11 and the cover 12 has a component in the front-to-back direction and left-to-right direction of the vehicle body 3, so that the force generated by the vehicle body 3 on the shock absorber 1 when it moves forward, backward or turns can be absorbed, so that the force acting on the vehicle-mounted device body 2 when the vehicle moves forward, backward or turns can be buffered.

[0031] In the specific implementation process of this embodiment 1, Figure 1 and Figure 4 As shown, the first axis a is arranged at an inclination angle with the front-rear direction of the vehicle body 3, and the inclination angle k is an acute angle or an obtuse angle.

[0032] It can be understood that the first axis a is set at an inclination angle with the front-to-back direction of the vehicle body 3, that is, the relative sliding direction of the base 11 and the cover body 12 is set to be inclined up and down with the front-to-back direction of the vehicle body 3, so that the relative sliding direction of the base 11 and the cover body 12 has components in the forward and backward directions and the up and down directions of the vehicle body 3, and can absorb the force generated by the vehicle body 3 on the shock absorber 1 when the vehicle body 3 moves forward and backward or bumps up and down, that is, it can provide buffering for the vehicle-mounted equipment body 2 when the vehicle body 3 moves forward, backward, or bumps up and down.

[0033] In the specific implementation process of this embodiment 1, Figure 1 As shown, the sliding structure includes a sliding member 111 and a first slideway 1121 . The first slideway 1121 is disposed on the base 11 and extends along the first axis a. The sliding member 111 is disposed on the cover body 12 . One end of the sliding member 111 is slidably disposed on the first slideway 1121 .

[0034] In this embodiment, the sliding member 111 of the cover 12 is slidable in the first slideway 1121 of the base 11 to achieve the relative sliding function between the cover 12 and the base 11. The first slideway 1121 extends along the first axis a, and the extension direction of the first slideway 1121 is the relative sliding direction between the cover 12 and the base 11.

[0035] It is understandable that in other embodiments, the sliding member 111 may be provided on the base 11, the first slide 1121 may be provided on the cover body 12 and extend along the first axis a, and one end of the sliding member 111 may be slidably provided on the first slide 1121, so that the cover body 12 may slide back and forth relative to the base 11.

[0036] In the specific implementation process of this embodiment 1, Figure 1 As shown, the base 11 includes two sliding members 111 and two first connecting parts 112 spaced apart on the second axis b, and the two first connecting parts 112 are each provided with a first slideway 1121. The cover 12 includes two second connecting parts 121 spaced apart on the second axis b, and the two second connecting parts 121 are each provided with a fixing hole 1211. Each sliding member 111 is penetrated by each fixing hole 1211 and one end is slidably connected to each first slideway 1121. The projection b1 of the second axis b on the horizontal plane is perpendicular to the projection a1 of the first axis a on the horizontal plane, and the second axis b is parallel to the horizontal plane.

[0037] In this embodiment, the sliding member 111 on the left side of the cover body 12 can slide in the first slideway 1121 on the left side of the base 11, and the sliding member 111 on the right side of the cover body 12 can slide in the first slideway 1121 on the right side of the base 11. The elastic member 13 is located between the two first connecting portions 112, and the second connecting portion 121 is located on the side of the first connecting portion 112 away from the elastic member 13. It can be understood that in other embodiments, the elastic member 13 can also be located between the two second connecting portions 121, and the first connecting portion 112 is located on the side of the second connecting portion 121 away from the elastic member 13.

[0038] In this embodiment, the fixing hole 1211 is a threaded through hole, and the sliding member 111 has a first threaded section 1111 and a sliding section 1112 connected to each other. The sliding member 111 is threadedly connected to the fixing hole 1211 through the first threaded section 1111 to realize the detachable connection between the sliding member 111 and the cover body 12, and the sliding member 111 is slidably inserted into the first slideway 1121 through the sliding section 1112 to realize the sliding connection between the sliding member 111 and the first slideway 1121. At the same time, the detachable connection between the sliding member 111 and the cover body 12 can facilitate the assembly of the shock absorber 1. For example, when assembling the shock absorber 1, after the elastic member 13 is installed on the base 11, the cover body 12 is installed on the base 11, the fixing hole 1211 and the first slideway 1121 are aligned, and the sliding member 111 is inserted into the fixing hole 1211 and tightened to complete the assembly of the shock absorber 1.

[0039] In the specific implementation process of this embodiment 1, Figure 1As shown, the shock absorber 1 further includes a buffer member 14 , and two sides of the buffer member 14 abut against the first connecting portion 112 and the second connecting portion 121 respectively.

[0040] In this embodiment, the number of the buffer members 14 can be two. A gap is formed between the first connection portion 112 and the second connection portion 121. In this embodiment, there are two gaps between the cover body 12 and the base 11 (i.e., one gap is formed between the first connection portion 112 and the second connection portion 121 on the left side, and one gap is formed between the first connection portion 112 and the second connection portion 121 on the right side). The two buffer members 14 are respectively arranged in the two gaps, so that when the vehicle body 3 turns, no matter whether the vehicle-mounted device body 2 tilts to the left or right, the buffer member 14 can well buffer the shock absorber 1 and play a role in buffering and energy absorption.

[0041] In other embodiments, the number of the buffer member 14 may be one, and the buffer member 14 is disposed in one of the two gaps between the cover 12 and the base 11 .

[0042] In other embodiments, the buffer component 14 may also be integrally formed, and the buffer component 14 includes a horizontal plate and two vertical plates vertically connected to the horizontal plate, the horizontal plate is parallel to the horizontal plane, and the two vertical plates of the buffer component 14 are inserted into the gap between the first connecting portion 112 and the second connecting portion 121.

[0043] In the specific implementation process of this embodiment 1, Figure 1 As shown, the buffer member 14 is provided with a second slideway 141 along the extension direction of the first axis a, and the sliding member 111 can slidably pass through the second slideway 141 .

[0044] In this embodiment, the size of the buffer 14 can be substantially the same as that of the first connection portion 112, so as to increase the buffer area between the first connection portion 112 and the second connection portion 121, thereby improving the buffer effect between the first connection portion 112 and the second connection portion 121. In order to enable the sliding member 111 to slide smoothly on the first slideway 1121, a second slideway 141 is provided on the buffer 14, and the sliding member 111 can slidably pass through the second slideway 141. Therefore, in this embodiment, the sliding member 111 is sequentially passed through the second slideway 141 and the first slideway 1121.

[0045] In the specific implementation process of this embodiment 1, Figure 1 As shown, the slidable space of the second slideway 141 is greater than or equal to the slidable space of the first slideway 1121.

[0046] In this embodiment, the slidable space in the second slideway 141 is greater than or equal to the first slideway 1121, so as to ensure that the second slideway 141 does not hinder the sliding member 111 from sliding smoothly on the first slideway 1121. Specifically, the width of the second slideway 141 is, for example, greater than or equal to the width of the first slideway 1121, and the length of the second slideway 141 is, for example, greater than or equal to the length of the first slideway 1121.

[0047] In the specific implementation process of this embodiment 1, Figure 1 As shown, the base 11 includes a first inclined portion 113 perpendicular to the first axis a, the cover body 12 includes a second inclined portion 122 perpendicular to the first axis a, one end of the elastic member 13 is connected to the first inclined portion 113, and the other end is connected to the second inclined portion 122.

[0048] In this embodiment, the elastic member 13 is extended along the first axis a. The first inclined portion 113 and the second inclined portion 122 are both perpendicular to the first axis a, so that the cover 12 and the base 11 can apply pressure to the elastic member 13 along the first axis a to ensure that the compression direction of the elastic member 13 is the same as the relative sliding direction of the cover 12 and the base 11, so that the cover 12 and the base 11 can slide stably.

[0049] In the specific implementation process of this embodiment 1, Figure 1 and Figure 2 As shown, a first assembling hole 1131 is provided on the first inclined portion 113 , and an assembling portion 131 is provided at one end of the elastic member 13 facing the first inclined portion 113 , and the assembling portion 131 is connected to the first assembling hole 1131 .

[0050] In this embodiment, the assembly portion 131 is provided with a thread, the first assembly hole 1131 is a threaded hole, and the elastic member 13 is threadedly connected through the assembly portion 131 and the first assembly hole 1131, so that the end of the elastic member 13 is tightly abutted against the first inclined portion 113, thereby avoiding the problem of untimely force transmission due to the existence of space for relative movement between the elastic member 13 and the base 11, thereby ensuring that the shock absorber 1 can provide a good shock absorbing effect.

[0051] In other embodiments, the assembling portion 131 may be inserted into the first assembling hole 1131 , and the assembling portion 131 and the first assembling hole 1131 are interference fit to fix the elastic member 13 to the first inclined portion 113 of the base 11 .

[0052] In the specific implementation process of this embodiment 1, Figure 1 and Figure 2As shown, a second assembling hole 1221 is provided on the second inclined portion 122, a third assembling hole 132 is provided at one end of the elastic member 13 facing the second inclined portion 122, and the shock absorber further includes an assembly member 15, which passes through the second assembling hole 1221 and is inserted into the third assembling hole 132.

[0053] In this embodiment, if Figure 1 and Figure 2 As shown, the third assembly hole 132 is a threaded through hole, and the assembly 15 has a connected plug-in section 151 and a second threaded section 152. The assembly 15 is threadedly connected to the third assembly hole 132 through the second threaded section 152 to achieve a fixed connection between the assembly 15 and the elastic member 13. The assembly 15 is inserted into the second assembly hole 1221 through the plug-in section 151 to achieve a connection between the assembly 15 and the cover body 12, so that the elastic member 13 and the second inclined portion 122 are tightly abutted, so that the force can be transmitted between the elastic member 13 and the cover body 12 in a timely manner.

[0054] In other embodiments, the assembly 15 may have two connected plug-in sections, which are respectively plugged into the second assembly hole 1221 and the third assembly hole 132 to achieve connection between the assembly 15 and the cover body 12 and the elastic member 13 .

[0055] In one embodiment, if Figure 2 As shown, a fourth assembly hole 16 is provided on the top of the cover 12, and the cover 12 is connected to the vehicle-mounted device body 2 through the fourth assembly hole 16. The fourth assembly hole 16 can be a screw, a bolt, a bolt or other parts that can play a fastening role.

[0056] The working principle of the shock absorber 1 provided in the embodiment 1 of the present invention is as follows: the vehicle-mounted device body 2 is connected to the top of the cover body 12, the base 11 is connected to the top of the vehicle body 3, the elastic member 13 is arranged in the space where the cover body 12 and the base 11 are buckled, and when the cover body 12 slides back and forth along the first axis a toward the base 11, the elastic member 13 is compressed, and the first assembly hole 1131, the second assembly hole 1221 and the assembly member 15 cooperate to make the two ends of the elastic member 13 close to the first inclined portion 113 and the second inclined portion 122. When the vehicle-mounted device body 2 on the top of the vehicle body 3 travels with the vehicle, the forces in various directions generated by the vehicle bumps, sudden braking, acceleration, deceleration, turning, etc. can be buffered by the buffer member 14 of the shock absorber 1 and the cover body 12 compressing the elastic member 13 along the first slide 1121.

[0058] In this embodiment, the shock absorber 1 is connected to the vehicle-mounted device body 2 through the cover body 12, so that the shock absorber 1 is integrated at the bottom of the vehicle-mounted device body 2 to form a whole with the vehicle-mounted device body 2, which is conducive to improving assembly efficiency.

[0059] In this embodiment, the shock absorber 1 absorbs the force transmitted to the vehicle-mounted equipment body 2 by the vehicle body 3 to reduce the amplitude of the shaking of the vehicle-mounted equipment body 2, or even avoid the shaking of the vehicle-mounted equipment body 2, thereby ensuring that the vehicle-mounted equipment body 2 can operate stably.

[0060] Another embodiment of the present application provides a vehicle, such as Figure 4 As shown, it includes the vehicle-mounted device of the above embodiment and a vehicle body 3 , and the vehicle body 3 is connected to a base 11 .

[0061] In this embodiment, a vehicle-mounted device body 2 is mounted on the vehicle body 3, and the vehicle-mounted device body 2 is, for example, a vehicle-mounted frequency jammer, so that the position of the vehicle-mounted frequency jammer can be flexibly arranged, thereby improving the jamming effect. At the same time, the shock absorber 1 absorbs the force transmitted to the vehicle-mounted device body 2 by the vehicle body 3, so as to reduce the amplitude of the shaking of the vehicle-mounted device body 2, and even avoid the shaking of the vehicle-mounted device body 2, thereby ensuring that the vehicle-mounted device body 2 can operate stably.

[0062] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
