Description

An integrated structure for an electric vehicle drive system Technical Field

[0001] This invention relates to the field of electric vehicle technology, specifically to an integrated structure for an electric vehicle drive system. Background Technology

[0002] In order to alleviate traffic congestion, parking occupying public space, and air pollution, some cities in China are vigorously promoting car-sharing as a transportation mode. Small and micro electric vehicles are ideal transportation tools for this mode. The front compartment of such electric vehicles is relatively small. How to reasonably arrange the car drive system in a small space and meet certain crash test standards has become a problem that car manufacturers need to face and strive to solve. The existing car drive system generally uses an independent motor controller and motor. The motor controller is located on the crossbeam of the front engine compartment, and the motor and reducer are matched and mounted on the body through a suspension. This is the most common drive system installation structure used in electric vehicles at present.

[0003] In current electric vehicle drive system integration structures, the controller needs to be aligned with the mounting components on the outer wall of the motor before being fixed in place with bolts. This requires workers to adjust the controller's position multiple times to align it with the motor mounting components, which is a cumbersome and inconvenient process. Therefore, we propose an electric vehicle drive system integration structure. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated structure for an electric vehicle drive system, in order to solve the problem mentioned in the background art that when installing the controller on the motor, it is necessary to first align the controller with the mounting components on the outer wall of the motor before fixing it with bolts. At this time, the operator needs to adjust the position of the controller multiple times to align it with the mounting components of the motor, which is a cumbersome and inconvenient process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An integrated structure for an electric vehicle drive system includes a motor. A hollow cylinder is symmetrically fixedly connected to the top of the motor's outer wall. Sliding grooves are formed on both sides of the outer wall of the hollow cylinder. Supporting springs are symmetrically fixedly connected to the bottom of each sliding groove. A guide plate is slidably connected inside the sliding groove. A rubber pad is adhered to one side of the guide plate. Embedded rods are disposed inside the hollow cylinder. The top ends of both embedded rods are fixedly connected to the bottom of a controller. A mounting groove is formed near the outer side of the embedded rods at the bottom of the controller. Shock-absorbing springs are equidistantly fixedly connected to the inner wall of the mounting groove. An arc-shaped plate is rotatably connected to one side of the motor's outer wall. The system also includes:

[0007] An auxiliary installation component is disposed inside the sliding groove and is located at the top of the outer wall of the motor.

[0008] A shock-absorbing assembly is disposed at the top of the mounting groove and is located on the top side of a plurality of shock-absorbing springs;

[0009] An auxiliary maintenance component is disposed on the top surface of the arc-shaped plate and located on one side of the outer wall of the motor.

[0010] Preferably, the auxiliary installation component includes a sliding groove, the sliding groove being formed inside the sliding groove, a fixed rod being fixedly connected inside the sliding groove, a slider being slidably adjusted at the outer end of the fixed rod, a top rod being fixedly connected at the middle position of the top of the slider, a sliding block being slidably embedded inside the sliding groove, the bottom end of the guide plate being fixedly connected to the top of the sliding block, an arc-shaped frame being fixedly connected at the top of the hollow cylinder near the outer side of the sliding groove, a threaded ring being fixedly connected at the top position of the outer wall of the hollow cylinder, and a threaded cylinder being rotatably connected at the top position of the outer wall of the embedded rod.

[0011] Preferably, the shock absorption assembly includes an airbag, which is adhered to the top of the mounting groove. The bottom of the controller is symmetrically fixedly connected to two mounting blocks near the two sides of the mounting groove. A rotating plate is rotatably embedded between the two mounting blocks. A plastic plate is adhered to one side of the top surface of the rotating plate. A hollow frame is fixedly connected to the outer wall of the threaded cylinder near the outer side of the plastic plate. A limiting block is fixedly connected to the bottom of the controller near the top surface of the rotating plate.

[0012] Preferably, the auxiliary maintenance component includes two sets of fixing plates, which are respectively fixedly connected to one side of the outer wall of the motor. A limiting plate is fixedly connected to one side of the bottom of the two fixing plates that are furthest apart. One end of the arc-shaped plate is rotatably embedded between the adjacent fixing plates. A slot is opened on one side of the top surface of the arc-shaped plate, and a locking rod is fixedly connected inside the slot. A first elastic band is glued to the other side of the top surface of the arc-shaped plate, and a hook is glued to one end of the first elastic band. A second elastic band is glued to the side of the motor near the space between the two arc-shaped plates.

[0013] Preferably, the inside of the threaded cylinder fits into the outer wall of the threaded ring, and one end of the support spring is fixedly connected to the bottom of the slider.

[0014] Preferably, the outer wall of the plastic sheet fits into the interior of the hollow frame, and the bottom surface of the limiting block is attached to the top surface of the rotating plate.

[0015] Preferably, one end of each of the plurality of shock-absorbing springs is fixedly connected to the top position of the outer wall of the embedded rod, and the top surface of the embedded rod is bonded to the bottom surface of the airbag.

[0016] Preferably, the inside of the hook fits into the outer wall of the locking rod, and a gap is left between the outer wall of the locking rod and the inner wall of the slot.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The integrated structure of this electric vehicle drive system uses a support spring and a fixing rod to facilitate the support of the slider's position, and a top rod to facilitate the support and movement of the sliding block's position. Combined with an arc-shaped frame, the sliding block moves along the inner wall of the arc-shaped frame, causing the sliding block to drive the guide plate to open outwards from the hollow cylinder. Simultaneously, the guide plate and rubber pad facilitate the guidance and movement of the embedded rod's position. The rubber pad ensures a tight fit between the embedded rod and the inside of the hollow cylinder, while simultaneously causing the guide plate to return to its original position within the sliding groove. This, along with the threaded cylinder and threaded ring, facilitates the installation and fixation of the embedded rod inside the hollow cylinder, thus conveniently installing and fixing the controller.

[0019] 2. The integrated structure of this electric vehicle drive system uses a plastic plate to clamp inside the hollow frame, thereby limiting the position of the rotating plate and maintaining the stability of the controller before installation. When the controller moves the embedded rod downwards, the friction between the embedded rod and the rubber pad causes the embedded rod to squeeze the airbag upwards. At the same time, the limiting block helps to limit the rotation angle of the rotating plate, thus separating the plastic plate from the hollow frame and stabilizing the controller. Combined with the shock-absorbing spring and airbag, the controller has high shock absorption during use, preventing the controller from vibrating when the motor starts, which could easily affect the normal operation of the controller.

[0020] 3. The integrated structure of this electric vehicle drive system uses a rotating connection between an arc-shaped plate and an adjacent limiting plate to facilitate adjustment of the arc-shaped plate's angle. The limiting plate, in conjunction with the arc-shaped plate, restricts the angle of the arc-shaped plate, facilitating disassembly and maintenance of the controller. The controller can be placed on the top surface of the two arc-shaped plates, and the first elastic band allows for adjustment of the hook position. The locking groove and locking rod further restrict the hook position, thus squeezing and confining the controller to the top surface of the two arc-shaped plates, maintaining its stability and facilitating maintenance of the motor and controller. The second elastic band further restricts the two arc-shaped plates stored on the outer wall of the motor, completing the storage of the two arc-shaped plates. Attached Figure Description

[0036] Please refer to Figures 1-10, which illustrate a technical solution provided by the present invention:

[0037] An integrated structure for an electric vehicle drive system includes a motor 1. A hollow cylinder 2 is symmetrically fixedly connected to the top of the outer wall of the motor 1. Sliding grooves 3 are formed on both sides of the outer wall of the hollow cylinder 2. Supporting springs 4 are symmetrically fixedly connected to the bottom of the sliding grooves 3. A guide plate 10 is slidably connected inside the sliding grooves 3. A rubber pad 11 is adhered to one side of the guide plate 10. Embedded rods 14 are provided inside the hollow cylinder 2. The top ends of both embedded rods 14 are fixedly connected to the bottom of a controller 16. A mounting groove 17 is formed near the outer side of the embedded rods 14 at the bottom of the controller 16. Shock-absorbing springs 18 are equidistantly fixedly connected to the inner wall of the mounting groove 17. An arc-shaped plate 27 is rotatably connected to one side of the outer wall of the motor 1. The system also includes:

[0038] The auxiliary installation component is located inside the sliding groove 3 and is situated at the top of the outer wall of the motor 1.

[0039] The shock absorption assembly is located at the top of the mounting slot 17 and is situated on the top side of multiple shock absorption springs 18.

[0040] The auxiliary maintenance component is located on the top surface of the arc plate 27 and is situated on one side of the outer wall of the motor 1.

[0041] In this embodiment, the auxiliary installation component includes a slide groove 5, which is opened inside the slide groove 3. A fixed rod 6 is fixedly connected inside the slide groove 5. A slider 7 is slidably adjusted at the outer end of the fixed rod 6. A top rod 8 is fixedly connected at the middle position of the top of the slider 7. A sliding block 9 is slidably embedded inside the slide groove 3. The bottom end of the guide plate 10 is fixedly connected to the top of the sliding block 9. An arc-shaped frame 12 is fixedly connected to the top of the hollow cylinder 2 near the outer side of the slide groove 3. A threaded ring 13 is fixedly connected at the top position of the outer wall of the hollow cylinder 2. A threaded cylinder 15 is rotatably connected to the top position of the outer wall of the embedded rod 14. This ensures that when the embedded rod 14 drives the threaded cylinder 15 to be located on the top side of the threaded ring 13, rotating the threaded cylinder 15 causes the threaded cylinder 15 to rotate and fit into the outer wall of the threaded ring 13, thereby installing and fixing the embedded rod 14 inside the hollow cylinder 2, thus facilitating the installation and fixing of the controller 16.

[0042] In this embodiment, the shock absorption assembly includes an airbag 19, which is bonded to the top of the mounting groove 17. The bottom of the controller 16 is symmetrically fixed to two mounting blocks 20 near the sides of the mounting groove 17. A rotating plate 21 is rotatably embedded between the two mounting blocks 20. A plastic plate 22 is bonded to one side of the top surface of the rotating plate 21. A hollow frame 23 is fixedly connected to the outer wall of the threaded cylinder 15 near the outer side of the plastic plate 22. A limiting block 24 is fixedly connected to the bottom of the controller 16 near the top surface of the rotating plate 21. This ensures that the controller 16 has high shock absorption during use due to the dual shock absorption of the shock-absorbing spring 18 and the airbag 19, preventing the controller 16 from vibrating when the motor 1 starts, which could easily affect its normal operation.

[0043] In this embodiment, the auxiliary maintenance component includes two sets of fixing plates 25, which are respectively fixedly connected to one side of the outer wall of the motor 1. The bottom ends of the two fixing plates 25 furthest apart are fixedly connected to a limiting plate 26. One end of the arc-shaped plate 27 is rotatably embedded between the adjacent fixing plates 25. A slot 28 is provided on one side of the top surface of the arc-shaped plate 27, and a locking rod 29 is fixedly connected inside the slot 28. A first elastic band 30 is glued to the other side of the top surface of the arc-shaped plate 27, and a hook 31 is glued to one end of the first elastic band 30. A second elastic band 32 is glued to the side of the motor 1 near the two arc-shaped plates 27, ensuring that pulling the second elastic band 32 and then pulling the two arc-shaped plates 27 will cause the two arc-shaped plates 27 to rotate to the outer wall of the motor 1. At this time, the two arc-shaped plates 27 are located inside the second elastic band 32. Releasing the second elastic band 32, due to the contraction of the second elastic band 32, makes it easy to restrict and store the position of the two arc-shaped plates 27.

[0044] In this embodiment, the inside of the threaded cylinder 15 fits into the outer wall of the threaded ring 13, and one end of the support spring 4 is fixedly connected to the bottom of the slider 7. This ensures that the slider 7 can move upward along the outer wall of the fixed rod 6 due to the support of the support spring 4, thereby driving the push rod 8 to move, and thus the push rod 8 can easily move the sliding block 9.

[0045] In this embodiment, the outer wall of the plastic plate 22 fits into the interior of the hollow frame 23, and the bottom surface of the limiting block 24 is attached to the top surface of the rotating plate 21. This ensures that the angle of rotation of the rotating plate 21 is limited due to the restriction of the limiting block 24, so that when the embedded rod 14 moves upward, it drives the plastic plate 22 to separate from the hollow frame 23, thereby stabilizing the controller 16.

[0046] In this embodiment, one end of each of the multiple shock-absorbing springs 18 is fixedly connected to the top of the outer wall of the embedded rod 14. The top surface of the embedded rod 14 is bonded to the bottom surface of the airbag 19, ensuring that due to the friction between the embedded rod 14 and the rubber pad 11, when the controller 16 moves downward, the embedded rod 14 presses upward against the airbag 19, thereby facilitating the subsequent shock-absorbing treatment of the embedded rod 14 by the shock-absorbing springs 18 and the airbag 19.

[0047] In this embodiment, the inside of the hook 31 fits with the outer wall of the locking rod 29, and there is a gap between the outer wall of the locking rod 29 and the inner wall of the slot 28. This ensures that pulling the hook 31 causes the first elastic band 30 to stretch, so that the hook 31 passes through the slot 28 and engages with the outer wall of the locking rod 29, thereby restricting the position of the hook 31 and thus squeezing and restricting the controller 16 to the top surface of the two arc-shaped plates 27.

[0048] In use, the electric vehicle drive system integrated structure of this embodiment firstly allows the slider 7 to move upward along the outer wall of the fixed rod 6 due to the support of the supporting spring 4. This causes the slider 7 to move the push rod 8. When the top end of the push rod 8 contacts the bottom end of the sliding block 9, the push rod 8 causes the sliding block 9 to move upward, allowing the sliding block 9 to move along the inside of the sliding groove 3. When the sliding block 9 leaves the sliding groove 3 and moves inside the arc frame 12, it moves along the inner wall of the arc frame 12. This causes the sliding block 9 to drive the guide plate 10 outward from the hollow cylinder 2. The side opening, in conjunction with the guide plate 10 and the rubber pad 11, facilitates the guiding movement of the embedded rod 14. When the outer wall of the embedded rod 14 contacts one side of the rubber pad 11, the embedded rod 14 fits tightly against the inside of the hollow cylinder 2, while simultaneously driving the guide plate 10 to return to the sliding groove 3. At this time, the embedded rod 14 drives the threaded cylinder 15 to be located on the top side of the threaded ring 13. Rotating the threaded cylinder 15 causes it to rotate and fit into the outer wall of the threaded ring 13, thereby installing and fixing the embedded rod 14 inside the hollow cylinder 2, thus conveniently installing and fixing the position of the controller 16.

[0049] Secondly, since the plastic plate 22 is snapped into the hollow frame 23, the position of the rotating plate 21 is restricted, thereby maintaining the stability of the controller 16 before installation. When the controller 16 drives the embedded rod 14 to move downward, due to the friction between the embedded rod 14 and the rubber pad 11, the embedded rod 14 squeezes the airbag 19 upward when the controller 16 moves downward. At the same time, due to the restriction of the limiting block 24, the rotation angle of the rotating plate 21 is restricted, thereby causing the plastic plate 22 to separate from the hollow frame 23, thereby relieving the instability of the controller 16. Due to the double shock absorption of the shock-absorbing spring 18 and the airbag 19, the controller 16 has high shock absorption when in use, avoiding the vibration of the controller 16 when the motor 1 starts, which may affect the normal use of the controller 16.

[0050] Next, due to the rotatable connection between the arc-shaped plate 27 and the adjacent limiting plate 26, pulling the arc-shaped plate 27 causes it to rotate to the top side of the limiting plate 26. The limiting plate 26 restricts the angle of the arc-shaped plate 27, facilitating disassembly and maintenance of the controller 16. This allows the controller 16 to be placed on the top surface of the two arc-shaped plates 27. Pulling the hook 31 causes the first elastic band 30 to stretch, allowing the hook 31 to pass through the slot 28 and engage with the outer wall of the locking rod 29. This restricts the position of the hook 31, thereby squeezing and restricting the controller 16 to the top surface of the two arc-shaped plates 27, maintaining the stability of the controller 16, thus facilitating the maintenance of the motor 1 and the controller 16 by the staff. Pulling the second elastic band 32, and then pulling the two arc-shaped plates 27, causes the two arc-shaped plates 27 to rotate to the outer wall of the motor 1. At this time, the two arc-shaped plates 27 are located inside the second elastic band 32. Releasing the second elastic band 32, due to the contraction of the second elastic band 32, makes it easy to restrict and store the position of the two arc-shaped plates 27.
