Description

Technical Field

[0001] This invention relates to the field of new energy vehicle reducer technology, specifically a fixed bracket for a new energy vehicle reducer. Background Technology

[0002] The engine and transmission are two core components of a car. The engine provides power, enabling the vehicle to run; while the transmission is crucial for transmitting power, transferring the engine's force to the wheels. More specifically, the reducer is an assembly that enables speed reduction and torque increase, differential speed between wheels, and changes in the direction of force transmission according to structural requirements. The reducer bracket is a structure used to connect the reducer to the vehicle body. During operation, the engine generates vibrations, which are transmitted to the transmission while providing power. The transmission then transmits these vibrations to the vehicle body through the bracket. To reduce the impact of vibrations on the vehicle and improve passenger comfort, damping mechanisms are often installed at the bracket. Existing damping mechanisms generally have a fixed damping value during operation. However, the engine encounters vibrations of varying amplitudes during driving or operation. Traditional damping mechanisms cannot adaptively adjust the damping value according to the vibration amplitude, resulting in less than ideal damping performance. Summary of the Invention

[0003] This invention provides a fixed bracket for a new energy vehicle reducer, which has a damping mechanism that can adaptively adjust the damping value according to the vibration amplitude of the bracket, resulting in better damping effect. This solves the problem mentioned in the background art that the damping value of existing damping mechanisms is generally fixed during operation, but the engine will encounter vibrations of different amplitudes during driving or operation.

The wing plate is provided with a plurality of through holes, and a flow limiting plate is provided on one side of the through holes. One end of the flow limiting plate is rotatably connected to the wing plate.

[0013] As an optional solution for the fixed bracket for a new energy vehicle reducer described in this invention, the limiting sleeve is annular and has a detachable extension claw, which is screwed to the limiting sleeve by threads.

[0014] The present invention has the following beneficial effects: 1. A fixed bracket for a new energy vehicle reducer, by setting a first shock absorption mechanism, includes a limiting sleeve fixed on a fixed column, the limiting sleeve being elastically connected to a support base, a plurality of top heads being provided on the support base, the top heads being arranged around the outside of the limiting sleeve, and an extension claw being provided on the limiting sleeve. When the reducer drives the connecting arm to rotate, it will drive the limiting sleeve to rotate synchronously. As the limiting sleeve rotates, the extension claw will abut against the top head. Hydraulic oil is provided in both the fixed groove and the first liquid storage tank. As the top head moves, the hydraulic oil in the first liquid storage tank will be pressed into the second liquid storage tank through the first flow channel. When the reducer vibrates up and down, it drives the support seat and buffer seat to rotate around the shaft on the connecting seat. An extension rod is provided at one end of the connecting seat and is inserted into the gap between the two first adjustment mechanisms. The first adjustment mechanism includes a movable block, which is elastically connected to the support seat. A gate rod is provided on the movable block, and one end of the gate rod is inserted into the first flow channel. When the buffer seat deflects upward or downward, the extension rod will abut against the movable block. Under the push of the extension rod, the movable block drives the gate rod to move into the first flow channel. The greater the amplitude of the gate rod entering, the smaller the flow rate of the first flow channel. In this way, the resistance encountered by the limit sleeve and the extension claw during rotation is greater, and the shock absorption effect is better.

[0015] 2. A fixed bracket for a new energy vehicle reducer, comprising a second damping mechanism including a limiting rod and a third reservoir, wherein a piston is installed in the third reservoir and the limiting rod is fixed on the piston. When the buffer seat deflects upward, the first extension plate presses downward. Under the push of the first extension plate, the limiting rod retracts inward toward the connecting seat. Driven by the limiting rod, the piston overcomes the resistance of the return spring and moves. Under the push of the piston, the hydraulic oil in the third reservoir enters the fourth reservoir through the second flow channel. When the buffer seat deflects downward... When the tension spring is charged, the second extension plate will contact the end cap on the transmission rod. Under the push of the second extension plate, the adjusting rod moves in the second flow channel. Since the middle of the second flow channel is conical, when the adjusting rod moves away from the connecting seat, the flow rate of the second flow channel gradually decreases with the movement of the adjusting rod and the protrusion. Then, when it deflects upward again under the drive of the tension spring, since the flow rate of the second flow channel has decreased, the buffer seat needs to overcome greater resistance to press the limiting rod into the third liquid storage tank, which can play a better damping and buffering role. In this technical solution, damping and buffering are achieved by setting a damping mechanism consisting of a second shock absorption mechanism and a fourth liquid storage tank, a second flow channel, and a second adjustment mechanism. The damping value of the damping mechanism can be adaptively adjusted according to the deflection amplitude of the buffer seat. Specifically, the greater the deflection amplitude of the buffer seat, the greater the vibration force. As the amplitude of the buffer seat increases, the damping value also increases, resulting in a better damping effect.

[0016] 3. This type of fixed bracket for a new energy vehicle reducer can adjust the return speed of the transmission rod and adjusting rod by setting a speed limiting mechanism. The specific working principle is as follows: a wing plate is provided on the transmission rod, and a through hole and a flow-limiting plate for partially blocking the through hole are provided on the wing plate. The flow-limiting plate can only rotate in one direction. Liquid is contained in the reservoir. When the transmission rod moves away from the buffer seat, it is affected by the resistance of the liquid, causing the flow-limiting plate to rotate, with one end moving away from the wing plate. Thus, during the movement of the transmission rod, the liquid can quickly... The fluid flows from one end of the wing plate to the other end through the through hole. When the transmission rod returns to its original position, the flow-limiting plate is in close contact with the wing plate due to the resistance of the fluid. At this time, the flow-limiting plate will block part of the through hole, reducing the flow rate of the through hole. As the flow rate of the through hole decreases, the resistance of the transmission rod and the wing plate will increase during the return process, and the return speed will slow down accordingly. In this way, when the transmission rod and the adjusting rod have not returned to their original positions, the first extension plate can contact the limiting rod, effectively ensuring the adjustment effect of the second adjusting mechanism on the second flow channel.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1 Please see Figures 1 to 6 This invention discloses a fixed bracket for a new energy vehicle reducer, including a connecting plate 1 and a buffer seat 2. One end of the connecting plate 1 is elastically connected to the buffer seat 2 via a tension spring 3. A connecting seat 4 is provided on the side of the connecting plate 1 near the buffer seat 2. The connecting seat 4 is rotatably connected to the buffer seat 2 via a rotating shaft. A support seat 5 is provided on the side of the buffer seat 2 away from the connecting seat 4. A fixed column 6 is provided on the support seat 5. The fixed column 6 is rotatably connected to the support seat 5. A first shock absorption mechanism is provided at the fixed column 6. A connecting arm 7 is provided at one end of the fixed column 6. The first damping mechanism includes a limiting sleeve 8, which is fixedly connected to a fixed column 6. The limiting sleeve 8 is elastically connected to a support base 5 via a torsion spring 9. The support base 5 is provided with a first liquid storage tank 501, which is annular. The support base 5 is provided with several fixing grooves 502, which are equidistantly arranged in annular shape within the support base 5. One end of each fixing groove 502 is connected to the first liquid storage tank 501. A first spring 503 is provided within each fixing groove 502. One end of the first spring 503 is provided with a top head 504. A second liquid storage tank 505 is symmetrically provided on the side of the support base 5 near the connecting seat 4. The second liquid storage tank 505 is connected to the first liquid storage tank 501 via a first flow channel 506. The support base 5 is also provided with two first adjustment mechanisms for adjusting the first flow channel 506.

[0026] The first adjustment mechanism includes a movable block 10, and the movable block 10 is elastically connected to the support base 5 through a second spring 26. One end of the movable block 10 is provided with a gate rod 11, and one end of the gate rod 11 passes through the support base 5 and extends into the first flow channel 506.

[0027] The end of the connecting seat 4 away from the connecting plate 1 is provided with an extension rod 12, one end of which extends into the gap between the two movable blocks 10.

[0028] This technical solution mainly includes a connecting plate 1 and a buffer seat 2. In actual use, the connecting plate 1 can be fixed to the vehicle body by welding or screw fixing. A connecting seat 4 is fixed on the connecting plate 1, and the connecting seat 4 is rotatably connected to the buffer seat 2. A support seat 5 is provided on the buffer seat 2, and a rotatable fixing post 6 is provided on the support seat 5. A connecting arm 7 is provided on the fixing post 6, and the connecting arm 7 is used to connect with the reducer. A first shock absorption mechanism is provided at the support seat 5, which includes a limiting sleeve 8 fixed on the fixing post 6. The limiting sleeve 8 is connected to the support seat 5. The elastic connection has several tops 504 on the support base 5, which are arranged around the outside of the limiting sleeve 8. The limiting sleeve 8 has an extension claw 801. When the reducer drives the connecting arm 7 to rotate, it will drive the limiting sleeve 8 to rotate synchronously. As the limiting sleeve 8 rotates, the extension claw 801 will abut against the tops 504. Hydraulic oil is provided in both the fixed groove 502 and the first liquid storage tank 501. As the tops 504 move, the hydraulic oil in the first liquid storage tank 501 will be pressed into the second liquid storage tank 505 through the first flow channel 506. During vibration, the reducer generally operates in multiple directions, generating displacement not only in the horizontal direction but also in the vertical direction. When the reducer vibrates up and down, it drives the support seat 5 and the buffer seat 2 to rotate around the shaft on the connecting seat 4. An extension rod 12 is provided at one end of the connecting seat 4, and the extension rod 12 is inserted into the gap between the two first adjustment mechanisms. The first adjustment mechanism includes a movable block 10, which is elastically connected to the support seat 5. A gate rod 11 is provided on the movable block 10, and one end of the gate rod 11 is inserted into the first flow channel 506. When the buffer seat 2 deflects upward or downward, the extension rod 12 will abut against the movable block 10. Under the push of the extension rod 12, the movable block 10 drives the gate rod 11 to move into the first flow channel 506. The greater the amplitude of the gate rod 11 entering, the smaller the flow rate of the first flow channel 506. Thus, the resistance encountered by the limiting sleeve 8 and the extension claw 801 during rotation is greater, and the vibration damping effect is better.

[0029] Example 2 This embodiment is an explanation based on Embodiment 1. For details, please refer to [link / reference]. Figures 1 to 6 The support base 5 has a first extension plate 13 on one side and a second extension plate 14 on the other side.

[0030] The connecting seat 4 is provided with a second shock absorption mechanism positioned opposite to the first extension plate 13. The second shock absorption mechanism includes a limiting rod 15 and a third liquid storage tank 16. A first piston 17 is provided in the third liquid storage tank 16. The first piston 17 is elastically connected to the connecting seat 4 through a return spring 18. One end of the first piston 17 is fixedly connected to the limiting rod 15. One end of the limiting rod 15 passes through the connecting seat 4 and extends to the outside of the connecting seat 4.

[0031] The connecting plate 1 is provided with a fourth liquid storage tank 101, and the fourth liquid storage tank 101 is connected to the third liquid storage tank 16 through the second flow channel 102. The middle part of the second flow channel 102 is conical.

[0032] The second flow channel 102 is provided with an adjusting rod 103, and one end of the adjusting rod 103 is provided with a protrusion 104.

[0033] The connecting plate 1 is provided with a second adjustment mechanism at one end near the connecting seat 4. The second adjustment mechanism includes a liquid storage cylinder 19 and a transmission rod 20. One end of the transmission rod 20 passes through the liquid storage cylinder 19 and is fixedly connected to the adjustment rod 103. The other end of the transmission rod 20 is provided with an end cap 21. The end cap 21 is elastically connected to the liquid storage cylinder 19 by a third spring 22.

[0034] The second flow channel 102 is provided with an adjusting rod 103, and one end of the adjusting rod 103 is provided with a protrusion 104.

[0035] A first extension plate 13 and a second extension plate 14 are provided on the support seat 5. A second damping mechanism corresponding to the first extension plate 13 is provided on the connecting seat 4. The second damping mechanism includes a limiting rod 15 and a third liquid storage tank 16. A first piston 17 is provided in the third liquid storage tank 16. The limiting rod 15 is fixed on the first piston 17. When the buffer seat 2 deflects upward, the first extension plate 13 will press downward. Under the push of the first extension plate 13, the limiting rod 15 will retract inward to the connecting seat 4. Under the drive of the limiting rod 15, the piston overcomes the resistance of the return spring 18 and moves. Under the push of the first piston 17, the hydraulic oil in the third liquid storage tank 16 enters the fourth liquid storage tank 101 through the second flow channel 102. When the buffer seat 2 deflects downward, the tension spring stores force, and the second extension plate 14 will abut against the end cap 21 on the transmission rod 20. Under the push of the second extension plate 14, the adjusting rod 103 moves in the second flow channel 102. Since the middle part of the second flow channel 102 is conical, when the adjusting rod 103 moves away from the connecting seat 4, the flow rate of the second flow channel 102 gradually decreases with the movement of the adjusting rod 103 and the protrusion 104. Subsequently, when the buffer seat 2 deflects upward again under the action of the tension spring 3, since the flow rate of the second flow channel 102 has decreased, the buffer seat 2 needs to overcome greater resistance to press the limiting rod 15 into the third liquid storage tank 16, which can play a better damping buffering role. In this technical solution, damping buffering is achieved by setting a damping mechanism composed of a second shock absorption mechanism and a damping mechanism composed of a fourth liquid storage tank 101, a second flow channel 102, and a second adjusting mechanism. The damping value of the damping mechanism can be adaptively adjusted according to the deflection amplitude of the buffer seat 2. Specifically, the greater the deflection amplitude of the buffer seat 2, the greater the vibration force, and as the amplitude of the buffer seat 2 increases, the damping value will also increase, resulting in a better damping effect.

[0036] Example 3 This embodiment is an explanation based on Embodiment 1. For details, please refer to [link / reference]. Figures 1 to 6 The transmission rod 20 is provided with a speed limiting mechanism, and the limiting mechanism includes a wing plate 24. The wing plate 24 is provided with several through holes 25, and a flow limiting plate 23 is provided on one side of the through holes 25. One end of the flow limiting plate 23 is rotatably connected to the wing plate 24.

[0037] The limiting sleeve 8 is annular and has a detachable extension claw 801, which is screwed to the limiting sleeve 8 by threads.

[0038] Since the transmission rod 20 is driven by the second extension plate 14, when the second extension plate 14 returns to its original position or moves away from the transmission rod 20, the transmission rod 20 will also return to its original position. During this process, if the return speed of the transmission rod 20 is too fast, that is, before the first extension plate 13 has pressed the limit rod 15 again, the transmission rod 20 returns to its original position with the adjusting rod 103, then the second adjusting mechanism will not be able to adjust the flow rate of the second flow channel 102. Therefore, this technical solution sets a speed limiting mechanism, which can adjust the return speed of the transmission rod 20 and the adjusting rod 103. The specific working principle is as follows: A wing plate 24 is provided on the transmission rod 20. The wing plate 24 has a through hole and a flow-limiting plate 23 for partially blocking the through hole 25. The flow-limiting plate 23 can only rotate in one direction. Liquid is contained in the liquid storage cylinder 19. When the transmission rod 20 moves away from the buffer seat 2, it is affected by the resistance of the liquid, and the flow-limiting plate 23 rotates, with one end moving away from the wing plate 24. In this way, during the movement of the transmission rod 20, the liquid can quickly pass through the through hole and flow from one end of the wing plate 24 to the other end of the wing plate 24. When the transmission rod 20 returns to its original position... When returning to its original position, due to the resistance of the liquid, the flow-limiting plate 23 is in close contact with the wing plate 24. At this time, the flow-limiting plate 23 will partially block the through hole 25, reducing the flow rate of the through hole 25. As the flow rate of the through hole 25 decreases, the resistance of the transmission rod 20 and the wing plate 24 will increase during the process of returning to their original position, and the return speed will also slow down. Thus, when the transmission rod 20 and the adjusting rod 103 have not returned to their original position, the first extension plate 13 can contact the limiting rod 15, and the second adjusting mechanism can achieve a better effect of adjusting the flow rate of the second flow channel 102.

[0039] In actual use, there is a risk of breakage of the extension claw 801. Therefore, this technical solution provides a detachable extension claw 801 on the limiting sleeve 8. The extension claw 801 is screwed to the limiting sleeve 8 by threads, making replacement more convenient.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
