Description

Technical Field

[0001] The utility model relates to the technical field of throttle detection, in particular to a detection table for the rotation of an electric vehicle throttle. Background Art

[0002] The electric vehicle throttle includes a fixed end and a movable end. The fixed end is rotatably connected to the movable end. A Hall element is installed at the connection between the fixed end and the movable end inside the fixed end. A magnet is installed near the Hall element inside the movable end. When the handlebar is rotated, the movable end drives the magnet to move, causing the Hall element to sense the change in magnetic field intensity and generating an electrical signal to be transmitted from the terminal to the controller for speed adjustment.

[0003] After retrieval, the Chinese patent publication number is CN219850895U, which discloses a detection device for an electric vehicle throttle. This patent detects the continuity inside the throttle by clamping the throttle body on the buckle, and then the stepping conveyor belt drives the throttle to move to the detection pointer to detect the continuity inside the throttle. Subsequently, the unqualified throttles are pushed into the collection box. This device has certain problems: the detection pointer can only detect the continuity inside the throttle and cannot detect the electrical signal output by the Hall element when the throttle rotates and adjusts the speed. The incomplete detection of the throttle leads to potential safety hazards in the follow-up. Content of the Utility Model

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] As Figures 1-4As shown in the figure, an electric vehicle handle rotation detection platform includes a workbench 101. Symmetrical legs 102 are welded to the bottom of the workbench 101. A display 103 is connected to the rear side of the top of the workbench 101 by screws. A transmission mechanism is arranged on the workbench 101. A bracket 302 is arranged above the workbench 101. A transmission mechanism is arranged on the bracket 302. The transmission mechanism includes a movable tube 401. The movable tube 401 is rotatably connected to the bracket 302. A gear 402 is connected to the front end of the movable tube 401 by a key. A connecting block 403 is connected to the rear end of the movable tube 401 by screws. A reset spring 405 is fixedly connected to one side of the connecting block 403. An auxiliary block 404 is connected to the top of the bracket 302 by screws. The auxiliary block 404 is located on one side of the connecting block 403. The auxiliary block 404 is fixedly connected to the reset spring 405. A rack 7 is connected to the top of the workbench 101 by screws. The rack 7 is located in front of the bracket 302. The rack 7 meshes with the gear 402. The gear 402 meshes with the rack 7 to drive the movable tube 401 to rotate. The movable tube 401 drives the magnet inside the handlebar to rotate, changing the magnetic field intensity sensed by the Hall element. The Hall element outputs an electrical signal to the terminal. After being detected by the detection probe 603, the value is transmitted to the display 103. The handlebar with a value not within the specified range is a non-conforming product. The movable tube 401 drives the connecting block 403 to rotate, stretching the reset spring 405. Subsequently, the gear 402 disengages from the rack 7. The reset spring 405 restores its deformation and generates a pulling force on the connecting block 403, resetting the movable tube 401.

[0024] A plurality of movable rods are rotatably connected to the workbench 101. A conveyor belt 202 is connected to the movable rods. A conveyor motor 201 is connected to the front end of the workbench 101 by bolts. The output shaft of the conveyor motor 201 is connected to one of the movable rods by a coupling. The conveyor motor 201 drives the conveyor belt 202 to move, and the conveyor belt 202 drives a plurality of fixing plates 301 to move.

[0025] A plurality of fixing plates 301 are connected to the conveyor belt 202 by screws. The bracket 302 is welded to the front end of the fixing plate 301. A limit buckle 303 is connected to the top of the fixing plate 301 by screws. A plurality of bumps 9 are fixedly connected inside the limit buckle 303. First, insert the movable end of the handlebar into the movable tube 401, then place the fixed end of the handlebar at the limit buckle 303 and press it down. There are a plurality of bumps 9 inside the limit buckle 303, and the bumps 9 increase the friction between the fixed end and the limit buckle 303 for easy positioning.

[0026] A fixed block 501 is fixedly connected to the top of the fixing plate 301. The fixed block 501 is located behind the limit buckle 303. A buckle 502 is connected to the top of the fixed block 501 by screws. Press the output terminal of the handlebar into the buckle 502. The buckle 502 is made of an elastic material and is slightly smaller than the terminal size, and can fix the terminal in the buckle 502.

[0027] A mounting plate 601 is welded to the top of the fixed plate 301. The mounting plate 601 is located at the rear end of the fixed block 501. The front end of the mounting plate 601 is connected to an electric telescopic rod 602 by bolts. A push plate is provided at the front end of the electric telescopic rod 602. A detection probe 603 is installed on the push plate. The electric telescopic rod 602 drives the push plate to move, driving the detection probe 603 to contact the terminal. The push rod 801 drives the clamping plates 802 to move towards each other, so that the clamping plates 802 fix the movable end of the handlebar.

[0028] A plurality of clamping grooves are formed in the movable tube 401. The plurality of clamping grooves are evenly distributed along the circumferential direction of the movable tube 401 on the inner wall of the movable tube 401. A push rod 801 is fixedly connected in the clamping groove. The push rod 801 is arranged along the radial direction of the movable tube 401. One end of the push rod 801 close to each other is fixedly connected to a clamping plate 802.

[0029] Working principle: During use, the conveyor motor 201 drives the conveyor belt 202 to move. The conveyor belt 202 drives a plurality of fixed plates 301 to move. The worker first inserts the movable end of the handlebar into the movable tube 401 on one side of the workbench 101, and then places the fixed end of the handlebar at the position of the limit buckle 303 and presses it downwards. A plurality of convex blocks 9 are arranged in the limit buckle 303. The convex blocks 9 increase the friction between the fixed end and the limit buckle 303 for easy positioning. Then, the output terminal of the handlebar is pressed into the buckle 502. The buckle 502 is made of an elastic material and the buckle 502 is slightly smaller than the size of the terminal, which can fix the terminal in the buckle 502. The electric telescopic rod 602 drives the push plate to move, driving the detection probe 603 to contact the terminal. The push rod 801 drives the clamping plates 802 to move towards the axis of the corresponding movable tube 401, so that the clamping plates 802 fix the movable end of the handlebar. The conveyor belt 202 drives the fixed plate 301 to move, so that the gear 402 meshes with the rack 7 to drive the movable tube 401 to rotate. The movable tube 401 drives the magnet inside the handlebar to rotate, changing the magnetic field intensity sensed by the Hall element. The Hall element outputs an electrical signal to the terminal. After the detection probe 603 detects it, the value is transmitted to the display 103. The handlebars with values not within the specified range are non-conforming products. The movable tube 401 drives the connecting block 403 to rotate, stretching the return spring 405. Then, the gear 402 disengages from the rack 7, and the return spring 405 restores its deformation and generates a pulling force on the connecting block 403, causing the movable tube 401 to return to its original position. The push rod 801 drives the clamping plates 802 away from the movable end of the handlebar. Then, the electric telescopic rod 602 drives the push plate away from the terminal. Then, the worker takes out the terminal from the buckle 502 and pulls up the fixed end of the handlebar to make the fixed end disengage from the limit buckle 303. Then, the handlebar is taken out, and the non-conforming products are collected and reworked.
