Description
Technical Field
[0001] This utility model relates to the field of PHEV motor bracket technology, and in particular to a PHEV motor bracket device with buffering and shock absorption function. Background Technology
[0002] PHEV motors refer to electric motors used in plug-in hybrid electric vehicles. PHEVs combine the advantages of internal combustion engines and electric motors, enabling short-distance driving using the electrical energy stored in the battery, while the internal combustion engine can continue to provide power when the battery charge is low. With the rapid development of hybrid electric vehicles, the design and installation of the powertrain are receiving increasing attention. During assembly and transportation, the mounting brackets of the powertrain must have good stability and shock resistance to avoid component damage and displacement caused by vibration. Therefore, a PHEV motor mounting device with buffer and shock absorption functions is needed.
[0003] Traditional PHEV motor brackets primarily use rigid structures for fixing and support. While this design can provide basic positioning functions, rigid brackets perform poorly in absorbing dynamic loads and mitigating vibrations. Due to the lack of effective buffering mechanisms, rigid structures cannot effectively isolate or absorb vibrations generated by the powertrain operation. These vibrations are not only directly transmitted to the vehicle body but may also impact the motor and other components, increasing the risk of damage to the motor during transportation. Prolonged vibration can lead to wear and tear on internal motor components, reducing their service life and reliability. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a PHEV motor bracket device with buffering and shock absorption functions.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A PHEV motor bracket device with buffering and shock absorption function includes a mounting bracket, which is L-shaped. An L-shaped plate is slidably connected to one end of the mounting bracket. A buffering mechanism for buffering the L-shaped plate is provided on the side wall of one end of the mounting bracket. A support plate is slidably connected to the inner side wall of the L-shaped plate. A shock absorption mechanism for damping the support plate is provided at the top of the L-shaped plate. A connecting plate is slidably connected to the top of the support plate. A U-shaped seat is fixed to the top of the connecting plate. First locking mechanisms for engaging the connecting plate are provided on the outer side walls of both ends of the U-shaped seat. A mounting plate is provided on the top of the U-shaped seat. A mounting base is fixed to the top of the mounting plate. Two columns are fixed to the inner side wall of the mounting base. A second locking mechanism for engaging the mounting plate is provided on the top of the U-shaped base. This device can install motors of different specifications during use, enhancing its overall practicality. Through the design of the buffering and shock absorption mechanisms, it can effectively absorb kinetic energy, reduce direct damage caused by vibration, reduce the impact of external impact on the motor, help improve the motor's stability, and extend its service life.
[0007] Preferably, the second locking mechanism includes a rectangular base, which is fixed to the middle of the bottom of the mounting plate. The outer wall of the rectangular base has a rectangular groove with a constricted opening. A fourth slider is slidably connected to the inner wall of the rectangular groove. A locking block is fixed to one end of the fourth slider. A second return spring is provided inside the rectangular groove and is located at the other end of the fourth slider. A rectangular hole is provided at the middle of the top of the U-shaped base, and the rectangular hole is adapted to the rectangular base. The two columns are pre-fixed on the surface of the mounting base. Pressing the locking block causes the fourth slider to move along the inner wall of the rectangular groove until the locking block retracts into the rectangular groove. At this time, the second return spring is in a compressed state. One end of the rectangular base is inserted into the rectangular hole. When the mounting plate and the top of the U-shaped base are in contact, the locking block is located below the rectangular hole. At this time, under the reaction of the compressed second return spring, the fourth slider is pushed to move in the opposite direction until the locking block is pushed out of the rectangular groove. The locking mechanism between the mounting plate and the U-shaped base is completed, thus completing the overall replacement of the mounting base and the two columns.
[0008] Preferably, the first snap-fit mechanism includes a support plate fixed to the outer wall of one end of the U-shaped seat. A sleeve is provided through the top of the mounting plate, and a circular block is slidably connected to the inner wall of the sleeve. A pull rod is fixed to the top of the circular block, and one end of the pull rod passes through the top of the sleeve. A first return spring is sleeved on the side wall of the pull rod. A connecting post is fixed to the bottom of the circular block, and one end of the connecting post passes through the bottom of the sleeve. Multiple through holes are linearly and equidistantly opened at the top of the support plate near one of the third sliding grooves, and the multiple through holes are adapted to the connecting post. Two third sliding grooves are symmetrically opened on the top of the support plate. A third sliding rod is fixed inside each of the two third sliding grooves. A third slider is sleeved on the side wall of each of the two third sliding rods, and the two third sliders are fixed to the bottom ends of the connecting plate respectively. Pulling the two pull rods causes the two circular blocks to move upward along the inner walls of the two sleeves respectively until the two connecting posts respectively connect with the two through holes. The hole disengages into the two sleeves. At this point, both first return springs are compressed, thus releasing the restriction on the connecting plate. Moving the connecting plate, it moves back and forth along the top of the support plate under the constraint of the two third sliding grooves, two third sliding rods, and two third sliding blocks. This moves the U-shaped seat, which in turn moves the mounting base and two columns, allowing the two columns to enter the mounting hole of the engine. This completes the installation of one end of the engine. At this point, the two pull rods are released. Under the reaction of the two compressed first return springs, the two circular blocks move in the opposite direction, pushing the two connecting columns into the other two symmetrically arranged through holes. The connecting plate is then fixed again. Similarly, following the above steps, the installation of the other end of the motor can be completed. This allows for the support of motors of different specifications without the need to replace different brackets, reducing the complexity of production and maintenance and improving the practicality of the device.
[0009] Preferably, the buffer mechanism includes two first sliding grooves, which are formed at one end of the side wall of the mounting bracket. A first sliding rod is fixed inside each of the two first sliding grooves. A first slider is fitted onto the side wall of each of the two first sliding rods, and the two first sliders are respectively fixed to the outer side walls at both ends of the support plate. A buffer spring is fitted onto the side wall of each of the two first sliding rods, and the two buffer springs are respectively located below the two first sliders. Through the two first sliding grooves and the two cooperating first sliding rods and two first sliders, when the motor is subjected to vibration, the support plate moves up and down along the inner side wall of the mounting bracket. During the movement, the compression and rebound of the two slides dynamically absorb energy, thereby achieving the buffering purpose and reducing damage to the motor and its support.
[0010] Preferably, the damping mechanism includes two second slide grooves, which are symmetrically opened at both ends of the inner sidewall of the L-shaped plate. A second slide rod is fixed inside each of the two second slide grooves. A second slider is fitted onto the sidewall of each of the two second slide rods, and both second sliders are fixed to the support plate. Multiple dampers are linearly fixed at equal intervals at the top of the L-shaped plate, and the output ends of the multiple dampers are fixed to the bottom of the support plate. Damping springs are fitted onto the outer sidewalls of the multiple dampers. These dampers can effectively absorb external impacts and vibrations, reducing the direct impact of these forces on the motor. Their telescopic characteristics allow them to adjust their length when subjected to external forces, thereby buffering the impact force. The damping springs fitted onto the outside of the dampers further absorb and disperse the external impact force through elastic deformation. The function of the damping springs is to provide additional elastic support, effectively reducing the direct impact force on the motor when external impacts occur, thus providing vibration damping and improving the motor's service life.
[0011] Preferably, the other end of the top of the mounting bracket has a round hole, and the two mounting brackets are installed on the vehicle frame through the two round holes and the mounting parts.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. This device has two symmetrical mounting brackets during use. The distance between the two connecting plates can be adjusted by the first snap-fit mechanism, and the column can be replaced by the second snap-fit mechanism to adapt to different specifications of engines without replacing the entire bracket, which reduces the complexity of production and maintenance and enhances the overall practicality.
[0014] 2. Through the design of the buffer and shock absorption mechanisms, the support plate can move up and down when the motor vibrates, effectively absorbing kinetic energy, reducing direct damage caused by vibration, reducing the impact of external impact on the motor, helping to improve the stability of the motor and extend its service life.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Reference Figure 1 - Figure 8A PHEV motor bracket device with buffering and shock absorption function includes a mounting bracket 1, which has an L-shaped structure. An L-shaped plate 4 is slidably connected to one end of the mounting bracket 1. A buffering mechanism for buffering the L-shaped plate 4 is provided on the side wall of one end of the mounting bracket 1. A support plate 5 is slidably connected to the inner side wall of the L-shaped plate 4. A shock absorption mechanism for damping the support plate 5 is provided on the top of the inner side of the L-shaped plate 4. A connecting plate 9 is slidably connected to the top of the support plate 5. A U-shaped seat 10 is fixed to the top of the connecting plate 9. First engaging mechanisms for engaging the connecting plate 9 are provided on the outer walls of both ends of the U-shaped seat 10. The top of the U-shaped base 10 is provided with a mounting plate 11, and a mounting seat 12 is fixed on the top of the mounting plate 11. Two columns 13 are fixed on the inner side wall of the mounting seat 12. The top of the U-shaped base 10 is provided with a second snap-fit mechanism for snapping the mounting plate 11. This device can be used to install engines of different specifications, which enhances the overall practicality. Through the design of the buffer mechanism and the shock absorption mechanism, it can effectively absorb kinetic energy, reduce the direct damage caused by vibration, reduce the impact of external impact on the motor, help improve the stability of the motor, and extend the service life of the motor.
[0026] Furthermore, the second snap-fit mechanism includes a rectangular base 26, which is fixed to the bottom center of the mounting plate 11. A rectangular groove 31 is formed on the outer wall of the rectangular base 26, and the rectangular groove 31 has a constricted opening. A fourth slider 32 is slidably connected to the inner wall of the rectangular groove 31. A locking block 33 is fixed to one end of the fourth slider 32. A second return spring 34 is provided inside the rectangular groove 31, and the second return spring 34 is located at the other end of the fourth slider 32. A rectangular hole 23 is formed at the top center of the U-shaped base 10, and the rectangular hole 23 is adapted to the rectangular base 26. The two uprights 13 are pre-fixed to the surface of the mounting base 12, and then pressed... The locking block 33 causes the fourth slider 32 to move along the inner wall of the rectangular slide groove 31 until the locking block 33 retracts into the rectangular slide groove 31. At this time, the second return spring 34 is in a compressed state, inserting one end of the rectangular seat 26 into the rectangular hole 23. When the top of the mounting plate 11 and the U-shaped seat 10 are in contact, the locking block 33 is located below the rectangular hole 23. At this time, under the reaction of the compressed second return spring 34, the fourth slider 32 is pushed to move in the opposite direction until the locking block 33 is pushed out of the rectangular slide groove 31, thus completing the locking mechanism between the mounting plate 11 and the U-shaped seat 10, and thus completing the overall replacement of the mounting seat 12 and the two columns 13.
[0027] Furthermore, the first snap-fit mechanism includes a support plate 24, which is fixed to the outer wall of one end of the U-shaped seat 10. A sleeve 25 is provided through the top of the mounting plate 11. A circular block 27 is slidably connected to the inner wall of the sleeve 25. A pull rod 29 is fixed to the top of the circular block 27, and one end of the pull rod 29 passes through the top of the sleeve 25. A first return spring 30 is sleeved on the side wall of the pull rod 29. A connecting post 28 is fixed to the bottom of the circular block 27, and one end of the connecting post 28 passes through the bottom of the sleeve 25. The top of the support plate 5 is close to one of the third... Multiple through holes 19 are equidistantly and linearly formed at the groove 20, and each through hole 19 is compatible with the connecting post 28. Two third grooves 20 are symmetrically formed at the top of the support plate 5. A third sliding rod 21 is fixed inside each of the two third grooves 20. A third slider 22 is fitted onto the sidewall of each of the two third sliding rods 21, and the two third sliders 22 are fixed to the bottom ends of the connecting plate 9. Pulling the two pull rods 29 causes the two circular blocks 27 to move upwards along the inner sidewalls of the two sleeves 25 until the two connecting posts 28 are respectively connected to their respective... The two through holes 19 disengage and enter the two sleeves 25. At this time, the two first return springs 30 are in a compressed state, which releases the restriction on the connecting plate 9. The connecting plate 9 is moved so that it moves back and forth along the top of the support plate 5 under the restriction of the two third slide grooves 20, the two third slide rods 21 and the two third sliders 22. This drives the U-shaped seat 10 to move, which in turn drives the mounting seat 12 and the two columns 13 to move. The two columns 13 enter the mounting hole of the engine, thus completing the installation of one end of the engine. At this time, the two pull rods 29 are released. Under the reaction of the two compressed first return springs 30, the two circular blocks 27 are pushed to move in the opposite direction, which in turn pushes the two connecting columns 28 into the two other symmetrically arranged through holes 19. The connecting plate 9 is fixed again. Similarly, the installation of the other end of the motor can be completed by following the above steps. This can support motors of different specifications without the need to replace different brackets, reducing the complexity of production and maintenance and improving the practicality of the device.
[0028] Furthermore, the buffer mechanism includes two first slide grooves 3, which are formed at one end of the side wall of the mounting bracket 1. A first slide rod 6 is fixed inside each of the two first slide grooves 3. A first slider 7 is fitted onto the side wall of each of the two first slide rods 6, and the two first sliders 7 are respectively fixed to the outer side walls at both ends of the support plate 5. A buffer spring 8 is fitted onto the side wall of each of the two first slide rods 6, and the two buffer springs 8 are respectively located below the two first sliders 7. Through the two first slide grooves 3 and the two first slide rods 6 and two first sliders 7 that cooperate with them, when the motor is subjected to vibration, the support plate 5 moves up and down along the inner side wall of the mounting bracket 1. During the movement, the compression and rebound of the two slide rods dynamically absorb energy, thereby achieving the buffering purpose and reducing damage to the motor and its support.
[0029] Furthermore, the damping mechanism includes two second slide grooves 14, which are symmetrically opened at both ends of the inner sidewall of the L-shaped plate 4. A second slide rod 15 is fixed inside each of the two slide grooves 14. A second slider 16 is fitted onto the sidewall of each of the two slide rods 15, and both second sliders 16 are fixed to the support plate 5. Multiple dampers 17 are linearly fixed at equal intervals at the top of the L-shaped plate 4, and the output ends of the multiple dampers 17 are fixed to the bottom of the support plate 5. Damping springs 18 are fitted onto the outer sidewalls of the multiple dampers 17. The multiple dampers 17 can effectively absorb external impacts and vibrations, reducing the direct impact of these forces on the motor. Their telescopic characteristics allow them to adjust their length when subjected to external forces, thereby buffering the impact force. The damping springs 18 fitted onto the outside of the dampers 17 further absorb and disperse the external impact force through elastic deformation. The function of the damping springs 18 is to provide additional elastic support, effectively reducing the direct impact force on the motor when external impacts occur, thus providing vibration damping for the motor and improving its service life.
[0030] Furthermore, a round hole 2 is provided at the other end of the top of the mounting bracket 1, and the two mounting brackets 1 are installed on the vehicle frame through the two round holes 2 and the mounting parts.
[0031] Working Principle: Two units of this device are symmetrically arranged during use, and the operating steps of both units are completely identical. Two mounting brackets 1 are installed on the vehicle frame via two round holes 2 and mounting parts. Two uprights 13, matching the spacing of their mounting holes, are replaced according to the engine specifications. The two uprights 13 are pre-fixed to the surface of the mounting base 12. During replacement, pressing the locking block 33 causes the fourth slider 32 to move along the inner wall of the rectangular groove 31 until the locking block 33 retracts into the rectangular groove 31. At this time, the second return spring 34 is compressed. One end of the rectangular seat 26 is then inserted into the rectangular hole 23. As the rectangular seat 26 moves, when the top of the mounting plate 11 and the U-shaped seat 10 contact, the locking block 33 is positioned below the rectangular hole 23. At this point, pressing... Under the reaction of the second return spring 34 in the compressed state, the fourth slider 32 is pushed to move in the opposite direction until the locking block 33 is pushed out of the rectangular slide groove 31, thus completing the locking mechanism between the mounting plate 11 and the U-shaped seat 10, and completing the overall replacement of the mounting seat 12 and the two columns 13. After the replacement is completed, pull the two pull rods 29, so that the two circular blocks 27 move upward along the inner sidewalls of the two sleeves 25 respectively, until the two connecting columns 28 disengage from the two through holes 19 and enter the interior of the two sleeves 25. At this time, the two first return springs 30 are in the compressed state, that is, the restriction on the connecting plate 9 is released. Move the connecting plate 9, so that the connecting plate 9, under the restriction of the two third slide grooves 20, the two third slide rods 21 and the two third sliders 22, moves along the support plate. 5. The top moves back and forth, thereby moving the U-shaped seat 10, which in turn moves the mounting base 12 and the two columns 13, allowing the two columns 13 to enter the mounting holes of the engine, thus completing the installation of one end of the engine. At this time, the two pull rods 29 are released, and under the reaction action of the two compressed first return springs 30, the two circular blocks 27 are pushed to move in the opposite direction, thereby pushing the two connecting columns 28 into the two other symmetrically arranged through holes 19, that is, the connecting plate 9 is fixed again. Similarly, following the above steps, the installation of the other end of the motor can be completed. This allows for the support of motors of different specifications without the need to replace different brackets, reducing the complexity of production and maintenance, and improving the practicality of this device. In use, through two The first slide groove 3, along with its two cooperating first slide rods 6 and two first sliders 7, allows the support plate 5 to move up and down along the inner wall of the mounting bracket 1 when the motor is subjected to vibration. During this movement, the compression and rebound of the two slide plates dynamically absorb energy, thus achieving a buffering effect and reducing damage to the motor and its bracket. Simultaneously, multiple dampers 17 effectively absorb external impacts and vibrations, reducing the direct impact of these forces on the motor. Their telescopic characteristics allow them to adjust their length when subjected to external forces, thereby buffering the impact. The damping springs 18, sleeved on the outside of the dampers 17, further absorb and disperse external impact forces through elastic deformation. The function of the damping springs 18 is to provide additional elastic support, ensuring that when an external impact occurs...This effectively reduces the direct impact force on the motor, providing vibration damping and extending the motor's lifespan.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
