DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] Reference Figure 1- Figure 9, an anti-vibration support structure for a vehicle-mounted transformer, including a mounting frame 9 and a transformer body 17, a shock absorbing assembly is arranged on the upper part of the mounting frame 9, an inflatable assembly is arranged between the shock absorbing assembly and the mounting frame 9, and the shock absorbing assembly provides power for the inflatable assembly.

[0042] An energy absorbing assembly is arranged on the shock absorbing assembly. The energy absorbing assembly includes an upper energy absorbing assembly and a lower energy absorbing assembly. The lower energy absorbing assembly includes a buffer block 18 . An air cavity 27 is provided in the buffer block 18 .

[0043] A horizontal buffer assembly is also provided on the mounting frame 9 , and the horizontal buffer assembly includes an expansion air pipe 21 .

[0044] The inflatable component inflates the buffer block 18 and the expansion air tube 21, and the buffer block 18 and the expansion air tube 21 can both achieve expansion deformation after being inflated.

[0045] The transformer body 17 is installed between the upper energy absorbing assembly and the lower energy absorbing assembly.

[0046] In a specific embodiment of the present invention, the shock-absorbing assembly is used to reduce the shock of the transformer body 17 during driving, so as to avoid the situation that the transformer body 17 is rigidly connected to the vehicle body and the transformer body 17 is subjected to large vibrations and then the transformer body 17 is damaged; at the same time, the inflatable assembly can be used to inflate the expansion air pipe 21 and the buffer block 18. During driving, when the vehicle passes through bad road conditions, such as uneven road surface, bumpy places or some muddy sections, that is, when the shock-absorbing assembly takes effect, the shock-absorbing assembly can drive the inflatable assembly to inflate the expansion air pipe 21 and the buffer block 18. After the expansion air in the expansion air pipe 21 is expanded, it can be attached to the vertical surface of the transformer body 17, so as to buffer the transformer body 17 horizontally, thereby reducing the horizontal vibration of the transformer body 17; and after the buffer block 18 is expanded by air intake, the lower energy-absorbing assembly is pressed against the transformer body The transformer body 17 is clamped with the upper energy absorbing component to prevent large shaking or vibration between the transformer body 17 and the shock absorbing component, so that during driving, the shock absorbing component is mainly used for shock absorption, and the horizontal buffer component is used to absorb the horizontal shock of the transformer body 17, and the lower energy absorbing component is used to absorb the vertical shock of the transformer body 17; when arriving at the destination, when the transformer body 17 starts to work, the expansion air pipe 21 is deflated, so that the expansion air pipe 21 does not contact the transformer body 17, reducing the influence on the heat dissipation of the transformer body 17, and the gas blown out by the expansion air pipe 21 can also dissipate the heat of the working transformer body 17; at the same time, during the working process, the vibration generated by the transformer body 17 itself is absorbed by the energy absorbing component; therefore, this scheme can perform all-round shock absorption on the transformer body 17 without affecting the heat dissipation of the transformer body 17.

[0047] In this solution, the upper energy absorbing assembly is arranged on the upper part of the shock absorbing assembly, the lower energy absorbing assembly is arranged on the lower part of the shock absorbing assembly, and the transformer body 17 is installed between the upper energy absorbing assembly and the lower energy absorbing assembly, which is equivalent to forming a clamp to clamp the transformer body 17. The mounting frame 9 is fixedly connected to the vehicle body.

[0048] The shock absorbing assembly includes a horizontal support 3, a crossbeam 1 and a spring shock absorber 5. The crossbeam 1 is fixedly arranged on the top of the horizontal support 3. A fixing block 25 is fixedly arranged on the inner side of the horizontal support 3. The top end of the spring shock absorber 5 is fixedly connected to the fixing block 25.

[0049] There are two groups of shock absorbing components, and the horizontal brackets 3 of the two groups of shock absorbing components are connected by the cross beam 1, that is, the two horizontal brackets 3 are fixedly arranged at the lower parts of the two ends of the cross beam 1 respectively; the spring shock absorber 5 can adopt existing conventional equipment, and its working principle is the same as that of the shock absorber of the car.

[0050] A mounting groove 22 is provided on the side of the mounting frame 9, and a fixing block 25 is slidably arranged in the mounting groove 22. The spring shock absorber 5 is located in the mounting groove 22, and its bottom end is fixedly connected to the bottom surface of the mounting groove 22. A base 11 is fixedly arranged at the bottom of the mounting frame 9.

[0051] Mounting grooves 22 are provided on both sides of the mounting frame 9, corresponding to the installation of two horizontal brackets 3 respectively; during driving, the up and down shaking caused by the bumps of the vehicle can be buffered and eliminated by the spring shock absorber 5. The specific movement action is that when the horizontal bracket 3 moves up and down, the spring shock absorber 5 provides damping and reset force to achieve the effect of buffering and shock absorption; and the process of the horizontal bracket 3 moving up and down provides power for the inflatable component.

[0052] The upper energy absorbing assembly includes a rubber block 2 , which is fixedly disposed at the bottom of the crossbeam 1 , and the rubber block 2 is in contact with the top of the transformer body 17 .

[0053] The bottom of the rubber block 2 is flat, thereby increasing the contact surface with the transformer body 17 .

[0054] The lower energy absorption component includes a screw rod 10 and a support frame 15, the top end of the screw rod 10 is connected to the horizontal support 3, and the bottom end is connected to the support frame 15; there are four screw rods 10, two in a group, corresponding to the two ends of the support frame 15 respectively; nuts are provided at the upper and lower ends of the screw rod 10, the upper nut is located above the horizontal support 3, and the lower nut is located below the support frame 15, and the nuts are used to adjust the height of the support frame 15. When installing the transformer body 17, first lower the support frame 15, then put the transformer body 17 on the support frame 15, and then raise the support frame 15 so that the top of the transformer body 17 touches the rubber block 2 to complete the installation.

[0055] The lower energy absorption component also includes an arc-shaped plate 19. Two slide grooves 14 are provided on the support frame 15. Buffer blocks 18 are arranged in the two slide grooves 14. Slide rods 13 are fixedly arranged at both ends of the arc-shaped plate 19. The two slide rods 13 are respectively slidably arranged in the slide grooves 14 and are both located between the two buffer blocks 18.

[0056] In this scheme, the arc plate 19 can undergo a certain deformation, and the top of the arc plate 19 is slightly higher than the top surface of the support frame 15 under normal conditions. After the transformer body 17 is installed, the top of the arc plate 19 is flush with the top surface of the support frame 15, and the two ends of the arc plate 19 will move to both sides, so that the corresponding slide bar 13 moves in the corresponding slide groove 14 and is blocked by the buffer block 18. At this time, the buffer block 18 is squeezed; when the buffer block 18 is inflated, it will expand and push the slide bar 13, so that the distance between the two ends of the arc plate 19 becomes slightly smaller, and then the arc plate 19 arches upward, further applying a tightening force to the transformer body 17.

[0057] The inflation assembly includes a piston cylinder 7 and a piston rod 6. A piston is arranged in the piston cylinder 7. The bottom end of the piston rod 6 is fixedly connected to the piston. A first support 4 is fixedly arranged on the side of the horizontal bracket 3. A second support 8 is fixedly arranged on the side of the mounting frame 9. The bottom end of the piston cylinder 7 is fixedly arranged on the second support 8. The top end of the piston rod 6 is fixedly connected to the first support 4. An air outlet and an air inlet are arranged at the bottom of the piston cylinder 7. A one-way valve is arranged at the air inlet.

[0058] The principle of the inflation assembly is similar to that of an air pump. When the piston rod 6 moves upward along with the horizontal bracket 3, air is drawn from the air inlet into the piston cylinder 7. When the piston rod 6 moves downward along with the horizontal bracket 3, the piston will discharge the gas in the piston cylinder 7 from the air outlet to achieve the inflation effect. The one-way valve at the air inlet only allows air to enter from the air inlet, but not to exit.

[0059] The buffer block 18 is provided with two air ports, one of which is connected to the air outlet of the piston cylinder 7 through the first pipeline 12, and a one-way valve is provided on the first pipeline 12. A pressure valve 26 is provided at the other air port of the buffer block 18, and the outlet of the pressure valve 26 is connected to the connecting pipe 24 at the bottom of the expansion air pipe 21 through the second pipeline 16.

[0060] When the inflation assembly outputs gas, the gas will enter the buffer block 18 through the first pipeline 12 to inflate the buffer block 18, and the one-way valve on the first pipeline 12 only allows the gas to enter the buffer block 18 from the piston cylinder 7, and cannot be reversed; when the air pressure entering the buffer block 18 reaches the set pressure, the excess gas will be discharged through the pressure valve 26, and then enter the second pipeline 16, and enter the expansion air pipe 21 from the connecting pipe 24, so that the expansion air pipe 21 expands.

[0061] In this embodiment, the expansion tube 21 is formed by winding a whole tube, which is arranged on the inner side of the mounting frame 9. The specific shape can be referred to Figure 3 and Figure 4 The overall shape of the expansion tube 21 is mesh-like, and such a configuration can leave a lot of space to facilitate the dissipation of the heat generated by the transformer body 17.

[0062] An exhaust pipe 20 is arranged at the rear side of the expansion pipe 21. One end of the exhaust pipe 20 is connected to the expansion pipe 21, and an electric control valve 23 is arranged at the connection position. The other end of the exhaust pipe 20 is closed. A plurality of exhaust holes are opened on the annular surface of the exhaust pipe 20, and the exhaust holes face the transformer body 17. A pressure sensor is also arranged at the electric control valve 23. When the pressure in the expansion pipe 21 exceeds the set pressure, the electric control valve 23 is opened to release air. At the same time, the electric control valve 23 is also used to open and release air when the transformer body 17 starts working after parking, so that the gas in the expansion pipe 21 is released. The expansion pipe 21 is deflated and does not contact the transformer body 17, further reducing the influence on the heat dissipation of the transformer body 17. When the electric control valve 23 is opened to release air, the gas will flow into the exhaust pipe 20 and then disperse from the exhaust holes of the exhaust pipe 20. At the same time, because the exhaust holes face the transformer body 17, the transformer body 17 can also be blown during exhaust, which plays a certain heat dissipation role. In order to facilitate the judgment of whether the vehicle is in the process of driving or in the process of using the transformer body 17 after parking, the pressure detected by the pressure sensor can be used to judge. If the vehicle is in the process of driving, the pressure of the expansion air pipe 21 is too high due to the continuous inflation, and then the air is deflated. At this time, the pressure detected by the pressure sensor is not stable enough, and it is judged to be driving; if the vehicle is parked, the inflation will not continue, and the pressure measured by the pressure sensor is relatively stable. If the measured pressure is relatively stable for a long time, it is judged to be parked.

[0063] Overall work flow: During driving, the vehicle shakes up and down due to the bumps caused by bad road conditions, and the shock-absorbing assembly is used to buffer and absorb shock, so that the transformer body 17 can shake up and down with a relatively gentle force, avoiding direct rigid vibration between the transformer body 17 and the vehicle body; and during the operation of the shock-absorbing assembly, its horizontal bracket 3 will drive the piston rod 6 to move up and down, and then inflate the buffer block 18, so that the buffer block 18 expands, pushing the slide bar 13 to move inward, and then the distance between the two ends of the arc plate 19 becomes smaller, so that the arc plate 19 arches upward, further tightening the transformer body 17, so that no large vibration will be generated between the transformer body 17 and the energy-absorbing assembly; when the air pressure in the buffer block 18 reaches the set air pressure After that, the excess gas will be released from the pressure valve 26 and then enter the expansion air pipe 21, causing the expansion air pipe 21 to expand, and then it will be close to the transformer body 17 to buffer it horizontally. If the pressure applied by the transformer body 17 to the expansion air pipe 21 is too large, resulting in excessive pressure in the expansion air pipe 21, or the pressure in the expansion air pipe 21 is large due to inflation, the pressure sensor can detect it, and then the electric control valve 23 is opened to release some air, and then the expansion air pipe 21 can be inflated again due to shaking, so that the expansion air pipe 21 can achieve the effect of buffering and absorbing energy for the transformer body 17, thereby achieving the effect of all-round shock absorption of the transformer body 17 during driving.

[0064] When the vehicle is parked after reaching the destination and then the transformer body 17 is used, the pressure sensor determines that the transformer body 17 is used after parking based on the relatively stable pressure measured over a long period of time, and then the electronically controlled valve 23 is opened to release gas, and the gas enters the exhaust pipe 20 from the expansion gas pipe 21 and is then discharged from the exhaust hole. The discharged gas is blown toward the transformer body 17, so it can speed up the heat dissipation to a certain extent. After the gas is released, the expansion gas pipe 21 will deflate, and then the expansion gas pipe 21 will not contact the transformer body 17, thereby reducing the influence on the heat dissipation of the transformer body 17.

[0065] A working method of a vehicle-mounted transformer anti-vibration support structure comprises the following steps:

[0066] Step 1: During driving, a shock absorbing component is used to reduce vibration of the transformer body 17 to prevent the transformer body 17 from being damaged after being subjected to strong vibration;

[0067] Step 2: When the shock absorbing assembly is working, kinetic energy can be provided to the inflatable assembly, so that the piston moves in the piston cylinder 7, and the buffer block 18 is inflated. Then the buffer block 18 expands and squeezes the two slide bars 13 inward, so that the arc plate 19 arches upward, further supporting the transformer body 17, and reducing the up and down shaking of the transformer body 17 between the upper energy absorbing assembly and the lower energy absorbing assembly;

[0068] Step 3: After the buffer block 18 is inflated, further inflating it will cause the internal air pressure to be too high. At this time, the pressure valve 26 opens to discharge the excess gas into the expansion air pipe 21. After the expansion air pipe 21 is inflated, it contacts the transformer body 17 to buffer the transformer body 17 horizontally.

[0069] Step 4: After arriving at the destination, the vehicle stops, the transformer body 17 starts to work, the electric control valve 23 opens, the gas in the expansion tube 21 enters the exhaust pipe 20, and is dispersed from the exhaust hole, so that the expansion tube 21 is deflated, thereby leaving the transformer body 17, and does not hinder the heat dissipation of the transformer body 17;

[0070] Step 5: The vibration generated by the transformer body 17 itself during operation is absorbed by the upper energy absorbing component and the lower energy absorbing component.

A pressure valve (26) is provided at the other air port of the buffer block (18), and the outlet of the pressure valve (26) is connected to the connecting pipe (24) at the bottom of the expansion air pipe (21) through a second pipeline (16).

6. The anti-vibration support structure for a vehicle-mounted transformer according to claim 5, characterized in that: An exhaust pipe (20) is arranged at the rear side of the expansion air pipe (21); one end of the exhaust pipe (20) is in communication with the expansion air pipe (21), and an electric control valve (23) is arranged at the connection position; the other end of the exhaust pipe (20) is closed; a plurality of exhaust holes are opened on the annular surface of the exhaust pipe (20), and the exhaust holes face the transformer body (17).

7. A working method of an on-board transformer anti-vibration support structure, the working method being applied to an on-board transformer anti-vibration support structure as claimed in claim 6, characterized in that: The steps include: Step 1: During driving, a shock-absorbing component is used to reduce vibration of the transformer body (17) to prevent the transformer body (17) from being damaged after being subjected to strong vibration; Step 2: When the shock absorbing component is working, kinetic energy can be provided to the inflatable component, so that the piston moves in the piston cylinder (7) and inflates the buffer block (18). Then, the buffer block (18) expands and squeezes the two slide bars (13) inward, so that the arc plate (19) arches upward, further supporting the transformer body (17), thereby reducing the up and down shaking of the transformer body (17) between the upper energy absorbing component and the lower energy absorbing component; Step 3: After the buffer block (18) is inflated, further inflating the buffer block (18) will cause the internal air pressure to be too high. At this time, the pressure valve (26) opens to discharge the excess air into the expansion air pipe (21). After the expansion air pipe (21) is inflated, it contacts the transformer body (17) to provide horizontal buffering for the transformer body (17); Step 4: After arriving at the destination, the vehicle stops, the transformer body (17) starts to work, the electric control valve (23) opens, the gas in the expansion air pipe (21) enters the exhaust pipe (20), and is released from the exhaust hole, so that the expansion air pipe (21) is deflated and leaves the transformer body (17), so as not to hinder the heat dissipation of the transformer body (17).
