[0030] Embodiment 1

[0031] See also Figure 1-9 The present invention provides a mobile charging vehicle battery shock absorbing device, comprising: a receiving component 1, wherein a receiving cavity for installing an energy storage battery is provided inside the receiving component 1; the receiving component 1 is connected between two shock absorbing brackets 2 arranged opposite to each other, the two shock absorbing brackets 2 are slidably arranged on two guide columns 3, an upper shock absorbing component 4 connected to the upper part of the two shock absorbing brackets 2 is provided on the lower surface of a top plate 7 at the top of the two guide columns 3, and a lower shock absorbing component 5 connected to the lower part of the two shock absorbing brackets 2 is provided on the upper surface of a bottom plate 8 at the bottom of the two guide columns 3.

[0032] The working principle and technical effects of the above technical solution are as follows:

[0033] The accommodating component 1 is detachably connected between the two shock-absorbing brackets 2, which is convenient for installing the energy storage battery in the accommodating cavity of the accommodating component 1 or taking out the energy storage battery. When the mobile charging vehicle vibrates during driving or during charging, the accommodating component 1 with the energy storage battery shakes in the up and down directions, which will drive the two shock-absorbing brackets 2 to slide on the two guide columns 3, so that energy absorption and shock reduction are performed through the upper shock-absorbing component 4 connected above the two shock-absorbing brackets 2, or through the lower shock-absorbing component 5 connected below the two shock-absorbing brackets 2, so as to effectively absorb vibration energy, have a good shock-absorbing effect on the energy storage battery, and ensure the safety and service life of the energy storage battery.

[0034] A plurality of heat dissipation holes are evenly arranged on the upper surface of the accommodating component 1 to prevent the energy storage battery from overheating. The shock absorbing device is integrally installed in the cargo box of the mobile charging vehicle. The top plate 7 and the bottom plate 8 are connected to the cargo box by bolts and nuts, and the stability of the connection must be ensured.

[0035] Embodiment 2

[0036] See also Figure 1-9The accommodating component 1 includes: an upper accommodating shell 101, a lower accommodating shell 102 and a connecting member; the four corners of the upper accommodating shell 101 and the lower accommodating shell 102 are connected by four connecting members, and each shock-absorbing bracket 2 is connected to two connecting members; the connecting member includes: an outer stud 103, the outer stud 103 is penetrated through the side plate of the upper accommodating shell 101 and the side plate of the lower accommodating shell 102, two nuts 104 screwed on the outer stud 103 respectively abut on the far side surfaces of the two side plates, a C-shaped ferrule 105 connected to the outer stud 103 is clamped on the side of the shock-absorbing bracket 2 through a C-shaped groove, and a screw rod 106 screwed on the C-shaped ferrule 105 is inserted into the longitudinal groove of the shock-absorbing bracket 2. A C-shaped rubber buffer pad is glued in the C-shaped groove of the C-shaped ferrule 105. The C-shaped ferrule 105 is slidably connected to the outer stud 103 through two end plates 107 . The twist ring 108 screwed on the outer stud 103 is located between the two end plates 107 , and the twist ring 108 is rotationally matched with the two end plates 107 .

[0037] The working principle and technical effects of the above technical solution are as follows:

[0038] The accommodating component 1 is composed of an upper accommodating shell 101, a lower accommodating shell 102 and a connecting member. A accommodating cavity for loading an energy storage battery is formed between the upper accommodating shell 101 and the lower accommodating shell 102. After installing the energy storage battery, the four corners of the upper accommodating shell 101 and the lower accommodating shell 102 are connected by four connecting members. The connection and disassembly of the connecting members and the upper accommodating shell 101 and the lower accommodating shell 102 are very convenient. By removing the nuts 104 above the four connecting members, the upper accommodating shell 101 can be controlled to separate from the four external studs 103. At this time, the energy storage battery is After the battery is loaded, the upper housing shell 101 is controlled to be reinstalled on the outer stud 103, and the upper nut 104 is tightened to fix it; the C-shaped clamping sleeve 105 connected to the outer stud 103 is clamped on the side of the shock-absorbing bracket 2 through the C-shaped groove, and the screw rod 106 screwed on the C-shaped clamping sleeve 105 is inserted into the longitudinal groove of the shock-absorbing bracket 2, thereby realizing the connection between the housing component 1 and the shock-absorbing bracket 2. When the housing component 1 needs to be removed, the screw rod 106 is rotated to make it disengage from the longitudinal groove of the shock-absorbing bracket 2, and the C-shaped clamping sleeve 1 can be removed. 05 is separated from the shock-absorbing bracket 2, and a nut can be threadedly connected to the connection between the screw rod 106 and the shock-absorbing bracket 2 to improve the connection stability; the C-shaped ferrule 105 is slidably connected to the outer stud 103 through two end plates 107, and the twist ring 108 screwed on the outer stud 103 is located between the two end plates 107, and the twist ring 108 is rotatably matched with the two end plates 107. The arrangement of this structure makes the relative position of the C-shaped ferrule 105 and the outer stud 103 adjustable, thereby adjusting the relative height position of the accommodating component 1 and the shock-absorbing bracket 2. Finally, the center of gravity of the mobile charging vehicle installed therein can be changed, affecting the center of gravity of the mobile charging vehicle. The mobile charging vehicle can be used in different mobile charging vehicles to meet the needs of vehicles under different terrain conditions. When adjusting, the contact position of the screw ring 108 and the outer stud 103 is changed, and the end plate 107 on the side of the C-shaped ferrule 105 can slide on the outer stud 103 to achieve regulation. The operation is very convenient. The C-shaped groove of the C-shaped ferrule 105 is glued with a C-shaped rubber buffer pad, which can not only improve the anti-slip effect and ensure the connection stability, but also play a role in buffering and shock absorption.

[0039] Embodiment 3

[0040] See also Figure 1-9 The shock-absorbing bracket 2 includes: a shock-absorbing crossbeam 201, a guide sliding hole slidably matched with the guide column 3 is provided in the middle of the shock-absorbing crossbeam 201, two shock-absorbing cross shafts 202 are rotatably connected to the shock-absorbing crossbeam 201, the two shock-absorbing cross shafts 202 are rotatably connected to the two shock-absorbing support arms 203, the two shock-absorbing support arms 203 are rotatably connected to the two shock-absorbing sliders 204, the two shock-absorbing sliders 204 are slidably arranged in the two shock-absorbing slide grooves of the bottom plate 8, and are slidably connected to the two anti-slip cross shafts assembled in the two shock-absorbing slide grooves; two shock-absorbing springs 205 are sleeved on each anti-slip cross shaft, one end of the two shock-absorbing springs 205 is connected to the shock-absorbing slider 204, and the other end of the two shock-absorbing springs 205 is connected to the side surfaces of the shock-absorbing slide groove.

[0041] The working principle and technical effects of the above technical solution are as follows:

[0042] The shock-absorbing crossbeam 201 is connected with the C-shaped sleeve 105 by snapping, and the external stud 103 can be inserted into the longitudinal groove of the shock-absorbing crossbeam 201. When vibration occurs, the accommodating component 1 equipped with the energy storage battery shakes in the up and down directions, which will drive the shock-absorbing crossbeam 201 of the two shock-absorbing brackets 2 to slide on the two guide columns 3. When the shock-absorbing crossbeam 201 moves up and down, it can drive one end of the two shock-absorbing support arms 203 to move up and down, and the other ends of the two shock-absorbing support arms 203 drive the two shock-absorbing sliding blocks 204 to slide in the two shock-absorbing sliding grooves of the bottom plate 8, thereby stretching and compressing the two shock-absorbing springs 205 sleeved on the anti-slip horizontal axis, so that the shock-absorbing springs 205 play a primary buffering and shock-absorbing role. The multiple shock-absorbing springs 205 also play a supporting and stabilizing role, ensuring that the accommodating component 1 equipped with the energy storage battery and the two shock-absorbing brackets 2 are in a relatively stable state as a whole and will not fall directly onto the bottom plate 8.

[0043] Embodiment 4

[0044] See also Figure 1-9 A gear 206 and a winding wheel 207 are fixedly connected to each shock-absorbing horizontal axis 202. The gear 206 is meshed with the tooth groove on the side of the guide column 3, and the winding wheel 207 is fixedly connected to one end of the elastic rope 208; the four elastic ropes 208 of the two shock-absorbing brackets 2 are connected to the four support bodies 6 fixedly connected to the four corners of the top plate 7 and the bottom plate 8.

[0045] The working principle and technical effects of the above technical solution are as follows:

[0046] When the shock-absorbing crossbeam 201 moves up and down, it can slide on the guide column 3, thereby changing the position where the gear 206 meshes with the tooth groove on the side of the guide column 3, thereby driving the gear 206 to rotate around its own axis. When the gear 206 rotates, it can drive the shock-absorbing horizontal shaft 202 and the winding wheel 207 to rotate. Since the winding wheel 207 is fixedly connected to one end of the elastic rope 208, the elastic rope 208 can be rolled up and stretched regardless of whether the winding wheel 207 rotates clockwise or counterclockwise. During the process of rolling up and stretching the elastic rope 208, since the elastic rope 208 is elastic, it can absorb part of the energy, thereby reducing the amplitude of vibration and playing a role in buffering and absorbing energy. Elastic ropes 208 with different elasticity or different stretching lengths can be provided to limit the maximum movement range of the accommodating component 1 and the shock-absorbing crossbeam 201, so that the movement range of the accommodating component 1 and the shock-absorbing crossbeam 201 can be accurately controlled, thereby more effectively absorbing and reducing vibration and improving shock absorption performance.

[0047] Embodiment 5

[0048] See also Figure 1-9The upper shock absorbing component 4 and the lower shock absorbing component 5 have the same structure, and are arranged oppositely on the top plate 7 and the bottom plate 8; the lower shock absorbing component 5 includes: a pressure column 501 fixedly arranged on the shock absorbing bracket 2, a pressure plug 502 fixedly arranged on the pressure column 501 and sealingly slidably arranged on the shock absorbing air cylinder 503, and the shock absorbing air cylinder 503 is fixedly arranged on the bottom plate 8.

[0049] The working principle and technical effects of the above technical solution are as follows:

[0050] The upper shock absorbing component 4 and the lower shock absorbing component 5 have the same structure and the same working principle. The working state and technical effect of the lower shock absorbing component 5 are described as an example below:

[0051] When the shock-absorbing bracket 2 moves downward, it can drive the pressure column 501 to move downward. At this time, the pressure column 501 drives the pressure plug 502 to slide downward in the shock-absorbing cylinder 503, and the gas in the shock-absorbing cylinder 503 can be compressed, so as to buffer and reduce shock through compressed air. This shock-absorbing method based on gas compression has the following advantages: First, excellent shock-absorbing performance: by absorbing and buffering the impact force through compressed gas, a more efficient shock-absorbing effect can be achieved, and the compression characteristics of the gas enable it to provide stable shock-absorbing performance in a wide load range; Second, strong adjustability: the hardness of the gas shock-absorbing can be adjusted by adjusting the pressure of the gas. In the present invention, an air pump can be connected to the outside of the shock-absorbing cylinder 503 to adjust the gas pressure inside the shock-absorbing cylinder 503. This adjustability allows the present invention to be optimized according to actual needs to adapt to different working conditions and load changes; Third, fast response speed: gas shock-absorbing can respond quickly to shock and vibration, because the compression and release of gas are very rapid, so that the impact of vibration on the equipment can be quickly alleviated.

[0052] The lower shock absorbing component 5 further includes: an inflatable airbag 504 glued to the bottom plate 8 or the accommodating component 1, a plurality of vents are longitudinally arranged on the inflatable airbag 504, and the inflatable airbag 504 is connected to the shock absorbing air cylinder 503 through the charging and discharging air pipe 505. A two-way pressure valve is arranged on the charging and discharging air pipe 505, and when the air pressure in the shock absorbing air cylinder 503 is greater than the preset air pressure value, the two-way pressure valve is automatically opened to allow the gas in the shock absorbing air cylinder 503 to be filled into the inflatable airbag 504 through the charging and discharging air pipe 505. An elastic buffer pad is glued to the side of the inflatable airbag 504 away from the bottom plate 8 or the accommodating component 1.

[0053] A two-way pressure valve is connected to the charging and discharging air pipe 505. In the initial state, the shock-absorbing air cylinder 503 is filled with gas. When buffering is performed, the pressure column 501 drives the pressure plug 502 to slide in the shock-absorbing air cylinder 503, which can compress the gas in the shock-absorbing air cylinder 503, thereby playing a role of buffering and shock reduction through compressed air. When the pressure in the shock-absorbing air cylinder 503 reaches a preset value, the two-way pressure valve automatically opens, and the compressed air of the shock-absorbing air cylinder 503 quickly enters the expansion airbag 504 through the charging and discharging air pipe 505 to inflate the expansion airbag 504. At this time, the expansion airbag 504 expands between the accommodating component 1 and the bottom plate 8 When the vibration amplitude is too large, the airbag plays a role of buffering to prevent the accommodating component 1 from hitting the bottom plate 8 and causing damage or explosion of the internal energy storage battery. Moreover, since the gas in the shock-absorbing air cylinder 503 is compressed air, the compressed air inflates the expansion airbag 504 at a faster speed. Compared with the ordinary air pump or manual inflation method, the compressed air can reach a higher inflation speed in a shorter time, thereby improving the inflation efficiency of the expansion airbag 504 and effectively ensuring the energy absorption and buffering effect. After buffering, since the shock-absorbing bracket 2 is a reciprocating rocking in the up and down directions, as the shock-absorbing bracket 2 moves upward, it can drive the pressure The column 501 moves upward, and at this time, the pressure column 501 drives the pressure plug 502 to slide upward in the shock-absorbing air cylinder 503, so that the air pressure in the shock-absorbing air cylinder 503 becomes smaller. At this time, the gas in the expansion airbag 504 can be re-injected into the shock-absorbing air cylinder 503. At this time, the shock-absorbing air cylinder 503 will not block the accommodating component 1, and a plurality of vents are longitudinally arranged on the expansion airbag 504 so that it does not affect the heat dissipation of the energy storage battery in the accommodating component 1. The expansion airbag 504 is made of elastic rubber and has a good deformation effect. The volume is effectively increased when inflated, and the volume is reduced after deflation without causing a large obstruction. The two-way pressure valve can also be replaced with an electric Control valve, a pressure sensor is arranged in the shock absorbing air cylinder 503, and the pressure sensor is electrically connected to the controller. When the pressure sensor detects that the air pressure in the shock absorbing air cylinder 503 is relatively high, it transmits a signal to the controller, and the controller controls the electric control valve to open, so as to realize the output of gas to the expansion air bag 504; in the upper shock absorbing component 4 and the lower shock absorbing component 5 of the present invention, the pressure column 501, the pressure plug 502 and the shock absorbing air cylinder 503 combined structure are arranged in at least four groups, which effectively ensures the shock absorbing, buffering and inflation effects; an elastic buffer gasket is also arranged on the expansion air bag 504, which further plays a buffering role and can also reduce the wear of the expansion air bag 504 during use.
