Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a motor vehicle safety braking detection device. Background Art

[0002] The braking system is a key safety device of a vehicle. If the braking performance is poor, the vehicle may not be able to slow down or stop in time during driving, resulting in accidents such as rear-end collisions and collisions. Through safe braking testing, it can ensure that the braking system can work normally and effectively reduce the risk of accidents.

[0003] Chinese patent CN116990042B discloses a motor vehicle brake performance test bench, including a first motor, a rotating disk, a mounting frame, a screw rod, a sliding frame, a connecting block, an electric push rod and a pressure block. The rotating disk is connected to the output shaft of the first motor to drive the rotating disk to rotate, the screw rod is rotatably connected to the mounting frame, the sliding frame is slidably connected to the mounting frame and can slide up and down, the sliding frame is threadedly connected to the screw rod, the connecting block is connected to the sliding frame, the electric push rod is rotatably connected to the connecting block, and the pressure block is hinged to the telescopic rod of the electric push rod to drive the pressure block to move downward to press the accelerator pedal and brake pedal of the test vehicle. The rotating disk is driven to rotate by the first motor, which can drive the steering wheel of the test vehicle to rotate and control the moving direction. Then, the pressure block is driven downward by the electric push rod, which can replace manual depressing of the brake pedal and accelerator pedal of the test vehicle, thereby eliminating the need for manual driving of the test vehicle for testing and improving safety.

[0004] The above-mentioned brake test bench only realizes the function of using a pressure block to replace manual control of the accelerator pedal and brake pedal, and cannot realize real simulation experiments such as vehicle braking collision. In real simulation experiments, safety ropes are usually used to protect the vehicle, but if the vehicle pedal is locked out of control, it is likely to collide with the braking area and cause injury to the test personnel. Moreover, when testing at different vehicle speeds, the tension on the rope varies. Due to large wear after long-term use, if the instantaneous tension is too large, the rope may break, causing a safety accident. Summary of the Invention

A hook lock 203 is provided; a winding wheel assembly 3, the winding wheel assembly 3 includes a winding wheel axle disk 301, a winding rope 302 and a front hook lock 303, the winding wheel axle disk 301 is fixedly assembled on the main base 101, a winding rope 302 is wound on the winding wheel axle disk 301, the end of the winding rope 302 is also fixedly connected to the front hook lock 303, and the winding wheel axle disk 301 and the release wheel axle disk 201 are connected by a synchronous belt drive; the motor vehicle safety brake detection device has a relative first direction x and a second direction y.

[0033] In actual application of this embodiment, when the motor vehicle safety brake test is carried out by the device, the main base 101 in the device is fixedly set on one side of the test site, and a release wheel axle disk 201 and a winding wheel axle disk 301 are rotatably set on the main base 101, and a release rope 202 and a winding rope 302 are respectively wound on the release wheel axle disk 201 and the winding wheel axle disk 301, and a rear hook lock 203 and a front hook lock 303 are provided at the ends of the release rope 202 and the winding rope 302, the rear hook lock 203 is pulled to the rear side of the motor vehicle to be tested, and the front hook lock 303 is pulled to the front side of the motor vehicle to be tested, and the release wheel axle disk 201 and the winding wheel axle disk 301 are connected by the same The release axle disc 201 and the winding axle disc 301 are connected by a synchronous belt drive. When the vehicle is accelerating or decelerating, since the release axle disc 201 and the winding axle disc 301 are connected by a synchronous belt drive, the instantaneous rotational linear speed of the release axle disc 201 and the winding axle disc 301 is equal to the instantaneous speed of the motor vehicle to be tested. During the detection process, when the vehicle is started, the release rope 202 and the rear hook lock 203 are pulled to move in the first direction x, which can synchronously drive the winding rope 302 and the front hook lock 303 to move in the first direction x. At this time, the release rope 202 on the release axle disc 201 is in a released state, and the winding rope 302 on the winding axle disc 301 is in a wound state. At this time, the speed detection mechanism provided on one side of the main base 101 4 is linked to the release wheel shaft disc 201 so that the release synchronization wheel 401 and the release synchronization shaft 402 in the speed detection mechanism 4 rotate coaxially and at the same speed as the release wheel shaft disc 201. During the rotation of the release synchronization shaft 402, the release synchronization disc 403 on the end side of the release synchronization shaft 402 rotates synchronously. Since a plurality of shaft seats 404 are arranged circumferentially on the release synchronization disc 403, and a first traction arm 405 is rotatably installed in the shaft seat 404, under the action of centrifugal force, the angle between the first traction arm 405 and the release synchronization disc 403 is related to the rotation speed of the release synchronization shaft 402. Therefore, when the motor vehicle leaves the braking area, the release synchronization shaft 402 can be adjusted according to the vehicle's travel speed. The speed adjusts the rotation angle of the first traction arm 405, and the first traction arm 405 can also pull the driven push plate 409 to move during the movement, so that the driven push plate 409 slidingly assembled on one side of the main base 101 along the second direction y moves synchronously. A transmission wheel component 5 is provided on one side of the driven push plate 409, and a lifting frame 506 and a trigger pressure rod 507 are provided in the transmission wheel component 5, which are linked to the release wheel shaft disk 201. The lifting frame 506 is slidably assembled on one side of the main base 101 along the second direction y, and the trigger pressure rod 507 on the end side is used to control the opening and closing of the brake assembly 6. The brake assembly 6 is provided with a hydraulic brake module 606 linked to the driven push plate 409.The hydraulic brake module 606 is used to control the feed of the hydraulic brake pads. By measuring the rotational speed of the release wheel axle disc 201, the expansion and contraction of the hydraulic brake pads can be controlled. When the motor vehicle to be inspected exits the brake detection area, the braking time on the release wheel axle disc 201 side is automatically adjusted according to the vehicle's speed. While ensuring that the vehicle stops within the effective range, the deceleration intensity is adjusted to achieve the purpose of slow braking, preventing the safety rope from being broken due to excessive tension, and effectively extending its service life.

[0034] In one case of this embodiment, the detection device is limited to braking detection over a straight-line distance, which will not be described in detail here.

[0035] See also Figure 7 In a preferred embodiment of the present invention, the motor vehicle safety brake detection device includes a speed detection mechanism 4, which includes a release synchronization wheel 401, a release synchronization shaft 402, a release synchronization disk 403, an axle seat 404 and a first traction arm 405. The release synchronization wheel 401 is coaxially fixedly connected to the release wheel axle disk 201, and one end of the release synchronization wheel 401 is fixedly assembled with a release synchronization shaft 402, and the end of the release synchronization shaft 402 is fixedly assembled with a release synchronization disk 403. A plurality of axle seats 404 are fixedly arranged circumferentially on the release synchronization disk 403, and the axle seats 404 are rotatably assembled on the release synchronization disk 403.

[0036] In actual application of this embodiment, the release synchronization wheel 401 and the release synchronization shaft 402 both rotate coaxially and at the same speed as the release wheel shaft disk 201, and during the rotation of the release synchronization shaft 402, the release synchronization disk 403 on the end side of the release synchronization shaft 402 rotates synchronously in the same direction, so that the multiple shaft seats 404 arranged circumferentially on the release synchronization disk 403 drive multiple first traction arms 405 to rotate simultaneously. The first traction arms 405 continuously rotate toward the release synchronization disk 403 under the action of centrifugal force, and the angle between the first traction arm 405 and the release synchronization disk 403 is related to the rotation speed of the release synchronization shaft 402. When the rotation speed of the release synchronization shaft 402 is faster, the angle between the first traction arm 405 and the release synchronization disk 403 is smaller. When the rotation speed of the release synchronization shaft 402 is slower, the angle between the first traction arm 405 and the release synchronization disk 403 is larger, and the opening angle on one side of the first traction arm 405 is adjusted according to the instantaneous speed of the motor vehicle to be inspected.

[0037] See also Figure 7In a preferred embodiment of the present invention, the speed detection mechanism 4 also includes a driven shaft disc 406 and a second traction arm 407, the driven shaft disc 406 is slidingly connected to the release synchronization shaft 402, and a plurality of slots are provided on the driven shaft disc 406. A plurality of second traction arms 407 are circumferentially arranged on the driven shaft disc 406, and one end of the second traction arm 407 is rotatably assembled in the slot of the driven shaft disc 406, and the other end of the second traction arm 407 is rotatably connected to the first traction arm 405.

[0038] In actual application of this embodiment, the driven shaft disc 406 is fixedly assembled on one side of the release synchronization shaft 402 and a plurality of slots are provided on the driven shaft disc 406. The number of the slots is matched with the number of the first traction arms 405. One end of the second traction arm 407 is rotatably installed in the slot, and the other end of the second traction arm 407 is rotatably connected to the end of the first traction arm 405. When the first traction arm 405 rotates following the release synchronization disc 403, the driven shaft disc 406 rotates synchronously under the traction of the first traction arm 405 and the second traction arm 407. The faster the speed of the release synchronization shaft 402, the closer the distance between the driven shaft disc 406 and the release synchronization disc 403. When the speed of the release synchronization shaft 402 is slower, the distance between the driven shaft disc 406 and the release synchronization disc 403 is farther.

[0039] See also Figure 7 In a preferred embodiment of the present embodiment, the speed detection mechanism 4 also includes a central counterweight block 408, a driven push plate 409, a limiting guide rod 410 and an elastic member 411, the central counterweight block 408 is fixedly assembled on the rotating shaft side of the first traction arm 405 and the second traction arm 407, the driven push plate 409 is arranged on one side of the main base 101 for sliding along the second direction y, and the driven push plate 409 is limitedly assembled on one end of the driven shaft disk 406, several of the limiting guide rods 410 are fixedly assembled on the main base 101, the driven push plate 409 is limitedly slidably assembled on the limiting guide rod 410, and several elastic members 411 are also sleeved on the limiting guide rod 410.

[0040] When the first traction arm 405 rotates with the second traction arm 407, the centrifugal force on the side of the middle counterweight 408 is stronger due to the larger mass on one side of the middle counterweight 408, thereby pulling the driven shaft disc 406 to move in the positive direction of the second direction y, so that the driven shaft disc 406 synchronously pulls the driven push plate 409 to move in the positive direction of the second direction y during the movement. One end of the driven push plate 409 is rotationally connected to the driven shaft disc 406, and the other end of the driven push plate 409 is slidably assembled on the limiting guide rod 410. One end of the limiting guide rod 410 is fixedly connected to the main base 101, and the other end of the limiting guide rod 410 is sleeved with an elastic member 411. The elastic member 411 limits the driven push plate 409 to move toward the side away from the release synchronization disc 403 in the default state.

[0041] See also Figure 4 In a preferred embodiment of the present invention, the motor vehicle safety brake detection device includes a transmission wheel component 5, which includes a first transmission shaft wheel 501, a second transmission shaft wheel 502, a third transmission shaft wheel 503, a fourth transmission shaft wheel 504 and a transmission screw 505. The first transmission shaft wheel 501, the second transmission shaft wheel 502, the third transmission shaft wheel 503 and the fourth transmission shaft wheel 504 are all arranged on one side of the main base 101 with a fixed axis, one end of the first transmission shaft wheel 501 is transmission-connected to the release synchronization wheel 401, and the other end of the first transmission shaft wheel 501 is meshed with the second transmission shaft wheel 502, one end of the third transmission shaft wheel 503 is coaxially fixedly connected to the second transmission shaft wheel 502, and the other end of the third transmission shaft wheel 503 is meshed with the fourth transmission shaft wheel 504, and the transmission screw 505 is fixedly assembled on the main base 101 and transmission-connected to the transmission screw 505.

[0042] In actual application of this embodiment, the first transmission shaft wheel 501 is fixedly arranged on one side of the main base 101, and the first transmission shaft wheel 501 and the release synchronous wheel 401 are connected by a synchronous belt transmission. The second transmission shaft wheel 502 is fixedly arranged on the main base 101, and the second transmission shaft wheel 502 is meshed with the first transmission shaft wheel 501. The third transmission shaft wheel 503 is fixedly arranged on the main base 101 and is coaxially fixedly connected with the second transmission shaft wheel 502. The fourth transmission shaft wheel 504 is fixedly arranged on the main base 101. The transmission screw 505 is fixedly arranged on the main base 101 and is connected to the fourth transmission shaft wheel 504 through a synchronous belt transmission, so that the release wheel axle disk 201 can synchronously drive the transmission screw 505 to rotate on the fixed axis during the rotation, so that the transmission screw 505 can engage and drive the lifting frame 506 to move in the second direction y during the rotation, and the movement direction of the lifting frame 506 in the second direction y is related to the rotation direction of the transmission screw 505.

[0043] In one case of this embodiment, the diameters of the first transmission shaft wheel 501, the second transmission shaft wheel 502, the third transmission shaft wheel 503 and the fourth transmission shaft wheel 504 are different, so that the rotation speed of the output shaft in the transmission structure is lower than the rotation speed of the input shaft, thereby forming a reduction transmission system between the first transmission shaft wheel 501 and the transmission screw 505. By controlling the number of rotations of the transmission screw 505, the moving distance of the lifting frame 506 in the second direction y is limited, and it is defaulted that when the lifting frame 506 moves to the extreme position, it stops moving after the detected vehicle leaves the braking area.

[0044] See also Figure 4 In a preferred embodiment of the present invention, the transmission wheel component 5 also includes a lifting frame 506 and a trigger pressure rod 507. The lifting frame 506 is slidably assembled on one side of the main base 101 along the second direction y and is engaged with the transmission screw 505. A trigger pressure rod 507 is also provided at the end of the lifting frame 506.

[0045] In actual application of this embodiment, the lifting frame 506 is slidably arranged on one side of the main base 101 along the second direction y, and the lifting frame 506 is engaged with the transmission screw 505. The transmission screw 505 can control the displacement distance of the lifting frame 506 in the second direction y during the rotation process, thereby adjusting the extension and retraction of the trigger pressure rod 507 in the second direction y, and when the trigger pressure rod 507 moves toward the side of the brake assembly 6 along the negative direction of the second direction y, due to the rotation of the transmission screw 505 The number of revolutions is related to the number of revolutions of the release wheel axle disc 201. Therefore, according to the length of the release rope 202 released on one side of the release wheel axle disc 201, when the motor vehicle to be inspected exits the braking area, the transmission screw 505 is synchronously engaged to drive the lifting frame 506 to move, and the trigger pressure rod 507 is pressed against one side of the brake assembly 6, thereby starting to brake the release wheel axle disc 201. By controlling the extension amount of the hydraulic brake pads in the brake assembly 6, the release wheel axle disc 201 is continuously decelerated to prevent the vehicle from losing control after exiting the braking area.

[0046] See also Figure 6 In a preferred embodiment of the present invention, the speed detection mechanism 4 also includes a driving gear plate 412, which is fixedly arranged at one end of the driven push plate 409. The motor vehicle safety brake detection device also includes a brake assembly 6, which includes a lifting frame 601, a side gear plate 602, a guide rod 603, a hydraulic cylinder 604 and a contact plate 605. The lifting frame 601 is slidably assembled on one side of the main base 101 along the second direction y, and a side gear plate 602 is provided at one end of the lifting frame 601. The guide rod 603 is fixedly arranged at one side of the main base 101 and is slidably connected to the lifting frame 601. The driving gear plate 412 is clamped on one side of the side gear plate 602. The hydraulic cylinder 604 is fixedly assembled in the lifting frame 601, and a contact plate 605 is movably provided on the hydraulic cylinder 604. The contact plate 605 is arranged toward the side of the trigger pressure rod 507.

[0047] When this embodiment is actually used, the driving tooth plate 412 is fixedly assembled on one end of the driven push plate 409, and the sliding position of the driven push plate 409 in the second direction y is related to the rotation speed of the release synchronization shaft 402. When the rotation speed of the release wheel shaft disk 201 side is faster, the distance between the driven push plate 409 and the release synchronization disk 403 in the second direction y is closer, so that the driving tooth plate 412 moves synchronously in the positive direction of the second direction y. Since the driving tooth plate 412 and the side tooth plate 602 are clamped and connected, the driving tooth plate 412 synchronously pulls the lifting frame 601 to slide along the guide rod 603 during the movement, so that the hydraulic cylinder 604 in the lifting frame 601 is synchronously approached to the side of the trigger pressure rod 507, so that the trigger pressure rod 507 moves to the side of the contact disk 605 in advance, thereby causing the hydraulic brake pad at one end of the brake assembly 6 to be released in advance to the end of the release wheel shaft disk 201 for deceleration.

[0048] In one case of this embodiment, the hydraulic brake module 606 and the hose 607, the hydraulic brake module 606 is fixedly arranged on the main base 101 and arranged in the brake groove 102, and a hydraulic brake pad is provided at one end of the hydraulic brake module 606. The hydraulic brake module 606 is connected to the hydraulic cylinder 604 through the hose 607, so that when the hydraulic cylinder 604 moves in the second direction y, since the hydraulic cylinder 604 and the hydraulic brake module 606 are connected through the hose 607, the extension amount of the hydraulic brake pad can be controlled according to the adjusted position of the hydraulic cylinder 604, so that the device can automatically brake after the motor vehicle leaves the braking area.
