Description

Technical Field

[0001] This utility model relates to the field of automotive motor assembly technology, and in particular to a new energy vehicle motor assembly device. Background Technology

[0002] New energy vehicles, including fuel cell vehicles (FCVs), hybrid electric vehicles (HEVs), and pure electric vehicles (EVs), all use electric motors to drive the wheels. Choosing the right motor is a crucial factor in improving the cost-effectiveness of various types of electric vehicles. In order to alleviate environmental pressure, it has become a trend for new energy vehicles to replace traditional vehicles.

[0003] A search revealed Chinese Patent Publication No. CN211998490U, which discloses a bending device for processing automotive parts and a new energy vehicle motor assembly device. The device includes a translation structure and a lifting structure. The translation structure comprises a support arm, a sliding rod, and a screw. Two support arms are vertically opposite each other, and sliding rods are symmetrically arranged horizontally on the upper part between the support arms. This technical solution uses hooks to attach the motor and then uses positioning rods to connect to the vehicle frame at the motor mounting position to improve motor assembly efficiency. However, because the motor is only fixed by hooks during use, it is prone to displacement due to shaking during device movement (such as translation or lifting operations), making precise fixing during assembly difficult and failing to meet usage requirements. Therefore, a new energy vehicle motor assembly device is proposed to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a new energy vehicle motor assembly device to solve the problems mentioned in the background.

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

[0006] A new energy vehicle motor assembly device includes a support frame, with two casters on each of the left and right sides of the bottom of the support frame, an electric telescopic rod extending through the top of the support frame to its inner side, a motor clamping mechanism at the output end of the electric telescopic rod, adjustment components on both the left and right sides of the inner wall of the support frame, and positioning components on both the front and rear sides of the adjustment components.

[0007] The motor clamping mechanism includes a mounting frame, which is fixedly installed at the output end of the electric telescopic rod and located inside the support frame. Connecting frames are fixedly installed on both the front and rear sides of the mounting frame. A servo motor extending to the inside of the connecting frame is fixedly installed on the outer side of the connecting frame. A first screw penetrating to the inside of the mounting frame is fixedly connected to the output shaft of the servo motor. A threaded cylinder extending to the inside of the mounting frame is threadedly installed on the outer side of the first screw. A clamping plate is fixedly installed at one end of the threaded cylinder located inside the mounting frame. Clamping pads are fixedly installed on the opposite sides of the two clamping plates.

[0008] Preferably, the adjustment component includes a fixed frame, and the number of fixed frames is two and fixedly installed on the left and right sides of the inner wall of the support frame. A second screw is rotatably installed on the inner bottom wall of the fixed frame, extending to its top. A handwheel is fixedly installed on the top of the second screw. A threaded block extending to the outside of the fixed frame is threaded on the outer side of the second screw. An installation block is fixedly installed at one end of the threaded block located on the outside of the fixed frame.

[0009] Preferably, the positioning component includes two sets of connecting arms, each set consisting of two connecting arms rotatably mounted at both ends of the mounting block. An extension arm extending to the outside of the connecting arm is movably mounted inside the connecting arm. A positioning rod extending through to the bottom of the extension arm is fixedly mounted on the top of the extension arm, and a locking stud that fits against the top of the connecting arm is threaded onto the top of the extension arm.

[0010] Preferably, the top of the mounting frame is fixedly equipped with guide columns located on both sides of the electric telescopic rod and penetrating the support frame, and both the mounting frame and the connecting frame are U-shaped structure designs.

[0011] Preferably, the clamping plate has an L-shaped structure design, and guide rods located on its upper and lower sides and penetrating the mounting frame are fixedly installed on the side of the clamping plate near the threaded cylinder.

[0012] Preferably, the top of the connecting arm has an elongated hole that matches the movement trajectory of the locking stud.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This new energy vehicle motor assembly device uses a servo motor in the motor clamping mechanism to drive the first screw to rotate, which in turn moves the threaded cylinder and clamping plate horizontally. The guide rod of the L-shaped clamping plate constrains the lateral displacement, allowing for quick adjustment of the clamping spacing to match the housing size of the new energy vehicle motor. This effectively prevents the motor from shifting due to shaking and improves the stability of the motor assembly.

[0015] This new energy vehicle motor assembly device, through the coordinated operation of an adjustment component and a positioning component, allows the threaded block in the adjustment component to drive the mounting block to move up and down, enabling the positioning component to flexibly adapt to the positioning height requirements of motors of different specifications. The extension arm of the positioning component extends and retracts within the connecting arm, and is fixed with the locking stud, allowing for quick adjustment of the extension length of the positioning rod. This ensures that the positioning rod can be accurately inserted into the fixing hole of the motor. By moving this device, the positioning rod is aligned with the position hole for the motor mounting on the vehicle frame. At this point, the electric telescopic rod controls the motor clamping mechanism to descend, conveniently positioning the motor installation position, reducing manual adjustment time, and improving assembly consistency.

[0025] Example

[0026] like Figures 1 to 4 As shown, this utility model provides a technical solution: a new energy vehicle motor assembly device, including a support frame 1, which serves as the main frame of the device. Two universal wheels 2 are fixedly installed on the left and right sides of the bottom of the support frame 1 to enable flexible movement of the device. An electric telescopic rod 3 is fixedly installed on the top of the support frame 1, extending through its inner side to provide vertical lifting power.

[0027] The output end of the electric telescopic rod 3 is fixedly connected to a motor clamping mechanism 4. The motor clamping mechanism 4 includes a mounting frame 41. The mounting frame 41 is fixedly installed at the output end of the electric telescopic rod 3 and located inside the support frame 1. Connecting frames 42 are fixedly installed on both the front and rear sides of the mounting frame 41. Guide columns 411 located on both sides of the electric telescopic rod 3 and penetrating the support frame 1 are fixedly installed on the top of the mounting frame 41. Both the mounting frame 41 and the connecting frame 42 are U-shaped structures. The guide columns 411 constrain the movement of the mounting frame 41 to prevent it from shaking or tilting during the lifting and lowering process.

[0028] A servo motor 43 extending to the inside of the connecting frame 42 is fixedly installed on the outer side. The output shaft of the servo motor 43 is fixedly connected to a first screw 44 that passes through the inside of the mounting frame 41. A threaded cylinder 45 extending to the inside of the mounting frame 41 is threadedly installed on the outer side of the first screw 44. A clamping plate 46 is fixedly installed at one end of the threaded cylinder 45 located inside the mounting frame 41. The clamping plate 46 has an L-shaped structure design. Guide rods 461 located on the upper and lower sides of the clamping plate 46 and passing through the mounting frame 41 are fixedly installed on the side of the clamping plate 46 near the threaded cylinder 45. Clamping pads 47 are fixedly installed on the opposite sides of the two clamping plates 46. This new energy vehicle motor assembly device, by setting the servo motor 43 in the motor clamping mechanism 4 to drive the first screw 44 to rotate, drives the threaded cylinder 45 and the clamping plate 46 to move horizontally. With the guide rods 461 of the L-shaped clamping plate 46 constraining the lateral displacement, the clamping distance can be quickly adjusted to adapt to the housing size of the new energy vehicle motor, effectively preventing the motor from shifting due to shaking and improving the stability of the motor assembly.

[0029] Adjustment components 5 are fixedly installed on both the left and right sides of the inner wall of the support frame 1. The adjustment components 5 include two fixed frames 51, which are fixedly installed on the left and right sides of the inner wall of the support frame 1. A second screw 52 is rotatably installed on the inner bottom wall of the fixed frame 51, extending through to its top. A handwheel 53 is fixedly installed on the top of the second screw 52. A threaded block 54 extending to the outside of the fixed frame 51 is threaded on the outside of the second screw 52. An installation block 55 is fixedly installed at one end of the threaded block 54 located on the outside of the fixed frame 51, so as to realize the height adjustment according to the needs and adapt to the installation requirements of motors of different specifications.

[0030] Positioning components 6 are movably mounted on both the front and rear sides of the adjusting component 5. Each positioning component 6 includes two sets of connecting arms 61, each set consisting of two arms rotatably mounted at both ends of the mounting block 55. An extension arm 62 extending outwards is movably mounted inside each connecting arm 61. A positioning rod 63, cylindrical in shape and with a diameter matching the mounting holes of the automotive motor and the vehicle frame, is fixedly mounted on the top of the extension arm 62. A locking stud 64, fitting against the top of the connecting arm 61, is threaded onto the top of the connecting arm 61. An elongated hole 641, matching the movement trajectory of the locking stud 64, is provided on the top of the connecting arm 61; its length determines the maximum extension / retraction of the extension arm 62. This new energy vehicle motor assembly device, through the coordinated operation of the adjustment component 5 and the positioning component 6, allows the threaded block 54 in the adjustment component 5 to drive the mounting block 55 to move up and down, enabling the positioning component 6 to flexibly adapt to the positioning height requirements of motors of different specifications. The extension arm 62 of the positioning component 6 extends and retracts within the connecting arm 61 and is fixed with the locking stud 64, which can quickly adjust the extension length of the positioning rod 63, ensuring that the positioning rod 63 can be accurately inserted into the fixing hole of the motor. By moving this device, the positioning rod 63 is aligned with the position hole for the motor on the vehicle frame. At this time, when the electric telescopic rod 3 controls the motor clamping mechanism 4 to descend, the motor installation position can be conveniently positioned, reducing manual adjustment time and improving assembly consistency.

[0031] The working process of this utility model:

[0032] Step 1: Push the device above the new energy vehicle motor using the casters 2 at the bottom of the support frame 1, and control the motor clamping mechanism 4 to move downwards using the electric telescopic rod 3 so that the clamping plate 46 can clamp the motor housing. At this time, start the servo motors 43 on the front and rear sides of the mounting frame 41 to drive the first screw 44 to rotate, and the threaded cylinder 45 moves towards the center along the inner side of the mounting frame 41, causing the clamping plate 46 to horizontally retract and clamp the motor housing. During this process, the guide rod 461 constrains the lateral displacement of the clamping plate 46 to avoid the motor from shifting due to uneven force. The clamping distance is controlled by the rotation amount of the servo motor 43 to adapt to motors with different housing widths.

[0033] Step two: After the motor clamping mechanism 4 clamps the car motor, the electric telescopic rod 3 is reset. At this time, the entire device is moved above the vehicle frame, and the second screw 52 is driven to rotate by manually rotating the handwheel 53 in the adjustment component 5. This causes the threaded block 54 to move up and down along the inner bottom wall of the fixed frame 51, driving the mounting block 55 and the positioning component 6 to rise and fall as a whole. (The connecting arm 61 and the extension arm 62 in the positioning component 6 are locked and adjusted by the locking stud 64, so that the positioning rod 63 can be adapted to the fixing hole of the car motor.) This continues until the positioning rod 63 of the positioning component 6 passes through the fixing hole of the car motor. When the device moves to the motor mounting position above the vehicle frame, the second screw 52 is rotated again until the positioning rod 63 passes through the mounting hole of the motor on the vehicle frame to achieve positioning. At this time, the fixing hole of the car motor and the mounting hole of the vehicle frame are on the same axis as the positioning rod 63. Finally, the electric telescopic rod 3 is pressed down by starting the control to push the motor to the mounting position on the vehicle frame, completing the assembly process of a single motor and effectively preventing the car motor from shaking or shifting during the assembly process.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
