Description

Technical Field

[0001] The present invention relates to the field of new energy vehicles, and in particular to a device suitable for new energy vehicles that can detect and adjust the dynamic balance of wheels. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source. The dynamic balance of the wheels is very important. Unbalanced wheels will cause the vehicle to vibrate and make noise, affecting the user's riding comfort, easily making the driver fatigued, and easily leading to traffic accidents. Unbalanced wheels are prone to uneven wear and shortening their service life. Therefore, it is usually necessary to install balance blocks on the wheels to keep the wheels dynamically balanced under high-speed rotation.

[0003] Balance weights are divided into stick-on type and knock-on type. Before installing the balance weights, you need to lift the wheel, pry off the old balance weights, rotate the tire, and then stick or knock the appropriate balance weights into the appropriate position. The prior art usually requires a balancing machine to detect whether the wheel is balanced, and then manually stick or knock the balance weights onto the wheel. It is difficult to grasp the number of balance weights that need to be stuck or knocked in, and the prior art detects and adds balance weights separately, which is inconvenient to operate. Summary of the invention

The block adding mechanism 6 includes a special-shaped connecting rod 1 61, a special-shaped connecting rod 2 62, an arc-shaped slotted frame 63, a pressing wedge-shaped frame 64, a tenth reset spring 65, a second compression spring 66, a blocking plate 67 and an eleventh reset spring 68. The special-shaped connecting rod 1 61 is connected to one of the large wedge-shaped blocks 53, the special-shaped connecting rod 2 62 is connected to the other large wedge-shaped block 53, the special-shaped connecting rod 1 61 and the special-shaped connecting rod 2 62 are both connected to the arc-shaped slotted frame 63, and the arc-shaped slotted frame 63 is slidably connected to The pressing wedge frame 64 is used to squeeze the blocking plate 67 to move in the direction away from each other.

[0037] The wheel to be tested is mounted on the sleeve 22 by bolts, and the bidirectional motor 211 is manually controlled to rotate clockwise, so that the gear 23 and the sleeve 22 rotate clockwise. The gear 23 will drive the fixed rack 27 and the device thereon to move upward, and the first return spring 26 will be compressed accordingly. Through the cooperation of the detection rod 42 and the third return spring 43, the detection rod 42 can clamp the wheel to be tested. If the wheel to be tested is balanced, the wheel to be tested will not tip over during high-speed rotation. If the wheel to be tested is unbalanced, the wheel to be tested will tilt to one side during high-speed rotation. The upper part of the wheel to be detected is tilted toward the direction close to the special-shaped motor frame 21, and the wheel to be detected rotating at high speed will squeeze the three detection rods 42 and the device thereon to move in the direction away from the special-shaped motor frame 21, and the three third reset springs 43 will be compressed accordingly. Through the cooperation of the three limiting wedge blocks 48 and the three fourth reset springs 49, the three limiting wedge blocks 48 can clamp the three spines 44 to prevent the three spines 44 and the device thereon from resetting. The degree of inclination of the wheel to be detected is different, and the distance of squeezing the detection rod 42 is different.

[0038] A plurality of balancing blocks are placed inside the arc-shaped slotted frame 63, and each balancing block is in contact with each other, and one of the balancing blocks is in contact with the second compression spring 66. A balancing block is also placed inside the pressing wedge frame 64, and the two-way motor 211 is manually controlled to stop operating. The special-shaped rising frame 24 and the device thereon will be reset under the reset action of the first reset spring 26. When the fixed rack 27 is reset, it will drive the gear 23 to reverse. Due to the action of the overrunning clutch 210, the gear 23 will not transmit the reversing force to the other output shaft of the two-way motor 211. At the same time, the three ratchet bars 44 will push the three pressing wedge frames 51 to move downward, and the three eighth reset springs 52 will be compressed accordingly. The three pressing wedge frames 51 will push one of the large wedge blocks 53 to move in the direction away from the special-shaped rising frame 24, so that One of the balancing blocks inside the middle pressing wedge frame 64 can be glued to the wheel to be tested, and the wheel to be tested will squeeze one of the pressing wedge frames 64 to move towards the direction close to the special-shaped connecting rod 61, and one of the tenth return springs 65 will be compressed accordingly, and one of the pressing wedge frames 64 will squeeze one of the pairs of blocking plates 67 to move away from each other, and one of the pair of eleventh return springs 68 will be stretched accordingly, so that one of the pairs of blocking plates 67 no longer blocks the balancing block inside one of the arc-shaped slotted frames 63, and one of the compressed second compression springs 66 will push the balancing block inside one of the arc-shaped slotted frames 63 to move away from the special-shaped connecting rod 61 under the action of its elastic force, so that the balancing block can be added to the inside of one of the pressing wedge frames 64.

[0039] When the three ratchet bars 44 and the devices thereon move in a direction away from the special-shaped motor frame 21, the three ratchet bars 44 will push the three swing wedge blocks 414 to swing, and the three torsion springs 415 will be compressed accordingly. When the three ratchet bars 44 are separated from the three swing wedge blocks 414, the three swing wedge blocks 414 will be reset under the reset action of the three torsion springs 415.

[0040] By adjusting the position of the nut 33, the device is adapted to wheels of different thicknesses, and the cooperation between the sliding tooth 28 and the second return spring 29 ensures that the fixed rack 27 and the gear 23 will not be separated.

[0041] The manually controlled bidirectional motor 211 is started again, and the three reset wedge frames 502 will squeeze the three limit wedge blocks 48 to move downward, and the three fourth reset springs 49 will be compressed accordingly, so that the three limit wedge blocks 48 will no longer jam the three spines 44, and the three spines 44 will be reset by one unit under the reset action of the three third reset springs 43. In this process, the three spines 44 will squeeze the three swing wedge blocks 414 and the devices thereon to move, and the fifth reset spring 411 will be compressed accordingly, so that the limit wedge block 2 412 will no longer block the rod limit block 46, and the compressed three first compression springs 47 will be restored accordingly, so that the three rod limit blocks 46 will move downward, and the three rod limit blocks 46 will block the three spines 44, so that the three spines 44 are reset by only one unit of distance.

[0042] Then, the three special-shaped slide rail frames 45 will squeeze the three reset wedge frames 502 to move away from the special-shaped motor frame 21, and the three seventh reset springs 503 will be compressed accordingly, so that the three reset wedge frames 502 are separated from the three limit wedge blocks 48, and the three limit wedge blocks 48 will be reset under the reset action of the three fourth reset springs 49, and the three limit wedge blocks 48 will push the three rod limit blocks 46 to reset, and the three first compression springs 47 will be compressed and reset. In this process, the three rod limit blocks 46 will push the three limit wedges The wedge block 412 moves, and the third and sixth return springs 413 are compressed accordingly, and then the third rod limit block 46 contacts the other side of the third limit wedge block 412, and the third limit wedge block 412 is reset under the reset action of the third and sixth return springs 413, so that the third limit wedge block 412 re-locks the third rod limit block 46, and then the third reset wedge frame 502 is reset under the reset action of the third and seventh return springs 503, and the third pressing wedge frame 51 is reset under the reset action of the third and eighth return springs 52.

[0043] Then, the bidirectional motor 211 is manually controlled to stop working, so that the balancing weight added to one of the pressing wedge frames 64 is also stuck to the wheel to be tested. By repeating the above operation, different numbers of balancing weights can be stuck on the wheel to be tested according to the different degrees of inclination of the wheel to be tested. When the three ratchet bars 44 and the devices thereon are reset to the initial position, the three ratchet bars 44 can no longer push the three pressing wedge frames 51, so that the wheel to be tested can be adjusted to balance. If the wheel to be tested tilts to the other side, it can also be adjusted to balance. Finally, the bidirectional motor 211 is manually controlled to stop working, the bolts are manually removed, and then the wheel that has been adjusted to balance can be removed. By repeating the above operation, the device can be used for a second detection and adjustment of the dynamic balance of the wheel.
