Description

Technical Field

[0001] The utility model relates to the technical field related to new energy vehicles, and more specifically, to a new energy vehicle test bench. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source or use conventional automotive fuels, adopt new on-board power devices, and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. Currently, people on the market often use test benches when testing the motors in new energy vehicles.

[0003] The test bench in the prior art generally fastens the motor and then connects it to the test equipment through a coupling for testing. However, the motor fastening on the test bench often relies on bolts for limiting, which makes it difficult to fasten and install according to motors of different sizes, thereby increasing the inconvenience of people limiting and fixing motors of different sizes, and cannot well meet people's daily use needs. The existing patent is a new energy vehicle motor test bench, and the patent authorization number is CN220171086U, which is provided with a motor, a first screw, a movable plate, a screw groove, a slide plate, a slide groove, a fixed The fixed plate, threaded sleeve, second screw, adjusting disk, limit plate and limit groove are arranged by placing the motor on the movable plate and rotating the adjusting disk so that the adjusting disk can drive the second screw to rotate, so that the second screw can rely on the threaded sleeve to push the limit plate to rely on the limit groove to limit and install the motor, and can be installed for motors of different sizes. In addition, the motor drives the first screw to rotate in the screw groove in the movable plate, and the movable plate can rely on the slide plate at the bottom to slide in the slide groove, which is convenient for people to move the motor to the appropriate position and connect it with the test equipment.

[0004] However, in patent authorization number CN220171086U, the motor is placed on a movable plate, and the adjusting disk can be rotated so that the adjusting disk can drive the second screw to rotate well, so that the second screw can rely on the threaded sleeve to push the limit plate to rely on the limit groove to limit and install the motor. Since the second screws are symmetrically arranged, during the process of limiting the installation of the motor, the distance between the two second screws is difficult to control, resulting in difficulty in matching the output shaft of the motor with the connecting shaft of the equipment, requiring repeated adjustments, and the operation is very cumbersome. Therefore, we propose a new energy vehicle test bench to solve the above-mentioned problems. Utility Model Content

Therefore, it is only necessary to use an electric push rod to adjust the height of the test equipment according to the test motor, and then use a coupling to connect the output shaft of the test motor to the connecting shaft of the test equipment, and then carry out the test work, which eliminates the need for repeated adjustment and is very convenient to operate.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Example:

[0033] See also Figure 1-4 A new energy vehicle test bench includes a base 1, a side panel 2 fixedly connected to the upper surface of the base 1, a placement plate 3 installed on the inner side of the side panel 2, an electric push rod 4 symmetrically installed between the placement plate 3 and the base 1, and a test device 5 installed on the upper surface of the placement plate 3. A centering positioning clamping mechanism is provided on one side of the side panel 2.

[0034] The centering positioning clamping mechanism includes an inner ring 6 provided on one side of the side plate 2, an outer ring 7 mounted on the outside of the inner ring 6, a connecting rod 8 fixedly connected between the inner ring 6 and the outer ring 7, a double-acting cylinder 9 mounted on the inner surface of the outer ring 7 and extending to the inside of the inner ring 6, a connecting seat 10 fixedly connected to the bottom of the outer ring 7, and a dovetail slider 11 symmetrically mounted on the bottom of the connecting seat 10;

[0035] The upper surface of the base 1 is provided with a dovetail slot 12 which is slidably connected to the dovetail slider 11;

[0036] Connecting brackets 13 fixedly connected to the base 1 are provided on both sides of the connecting seat 10, and a lead screw 14 screwed to the outer ring 7 is rotatably connected between the connecting brackets 13;

[0037] A drive motor 15 is installed on the connecting frame 13 near the edge of the base 1, and the power output end is connected to the lead screw 14.

[0038] The outer side wall of the side panel 2 is mounted with a PLC controller 17;

[0039] It should be noted that when the new energy vehicle test bench is in use, the motor for the new energy vehicle is placed on the inner side of the inner ring 6 (the motor for the new energy vehicle is cylindrical in shape), so that the output shaft of the test motor faces the test equipment 5;

[0040] By using the PLC controller 17 to control the movable ends of multiple double-acting cylinders 9 to work simultaneously, the test motors of different diameters can be clamped in the center, and then the driving motor 15 is driven to drive the screw 14 to rotate in conjunction with the connecting frame 13, so that the dovetail slider 11 moves in conjunction with the dovetail slot 12, thereby moving the centering positioning clamping mechanism toward the test equipment 5. The axis center line of the output shaft of the test motor and the axis center line of the connecting shaft of the test equipment 5 are on the same straight line in the longitudinal position. Therefore, it is only necessary to use the electric push rod 4 to adjust the height of the test equipment 5 according to the test motor, and then use the coupling to connect the output shaft of the test motor to the connecting shaft of the test equipment 5, and then perform the test work, which eliminates the need for repeated adjustments and is very convenient to operate.

[0041] like Figure 3 、 Figure 4 As shown, the inner bottom of the inner ring 6 is fixedly connected to a support plate 16 having an arc-shaped structure, and a through hole is opened at the portion of the support plate 16 corresponding to the double-acting cylinder 9;

[0042] It should be noted that by placing the motor to be tested on the support plate 16, the test motor is stably supported before clamping, without the need for manual support, which is conducive to the next clamping work and improves the safety of manual operation.

[0043] like Figure 1 、 Figure 3 As shown, three double-acting cylinders 9 are provided, and the angle between the axis of the inner ring 6 of two adjacent double-acting cylinders 9 is 120°, and the axis of the inner ring 6 and the axis of the connecting shaft of the test device 5 are located in the same plane in the vertical direction;

[0044] It should be noted that while ensuring the stability of the clamping of the test motor, the test motor can also be clamped in the center. The center line of the output shaft of the test motor and the center line of the connecting shaft of the test equipment 5 are located on the same straight line in the longitudinal position. Therefore, it is only necessary to use the electric push rod 4 to adjust the height of the test equipment 5 according to the test motor.

[0045] like Figure 2 As shown, both ends of the lead screw 14 are provided with a smooth structure, and a bearing is installed at the portion where the connecting frame 13 and the end of the lead screw 14 are combined. The end of the lead screw 14 close to the drive motor 15 passes through the connecting frame 13, and the through end of the lead screw 14 is connected to the power output end of the drive motor 15 through a coupling;

[0046] It should be noted that the friction between the lead screw 14 and the connecting frame 13 is reduced, and at the same time, the power transmitted by the drive motor 15 can be normally transmitted to the lead screw 14.

[0047] The PLC controller 17 is connected to the double-acting cylinder 9 through a magnetic switch. The model of the PLC controller 17 can be MM-40MR-12MT-700ES-A.

[0048] When in use: place the motor for new energy vehicles on the inner side of the inner ring 6 (the motor for new energy vehicles is cylindrical in shape), with the output shaft of the test motor facing the test equipment 5;

[0049] By using the PLC controller 17 to control the movable ends of multiple double-acting cylinders 9 to work simultaneously, the test motors of different diameters can be clamped in the center, and then the drive motor 15 is driven to drive the screw 14 to rotate in conjunction with the connecting frame 13, so that the dovetail slider 11 moves in conjunction with the dovetail slot 12, thereby moving the centering positioning clamping mechanism toward the test equipment 5. The axis center line of the output shaft of the test motor and the axis center line of the connecting shaft of the test equipment 5 are on the same straight line in the longitudinal position. Therefore, it is only necessary to use the electric push rod 4 to adjust the height of the test equipment 5 according to the test motor, and then use the coupling to connect the output shaft of the test motor to the connecting shaft of the test equipment 5, and then perform the test work.

[0050] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
