Description

Technical Field

[0001] This utility model belongs to the field of braking technology, specifically relating to a linkage-type auxiliary braking device. Background Technology

[0002] A secondary brake is a synchronizing device that assists in braking. It is usually installed between the driver's seat and the passenger seat, or on the passenger seat. When the user presses the secondary brake, the main brake will also be pressed down at the same time, thus achieving the braking effect. The secondary brake is often used to help the driver brake in emergency situations.

[0003] In related technologies, driving test training vehicles are often equipped with a secondary brake device. When in use, external personnel such as instructors are required to apply external force to drive the secondary brake to brake the vehicle. Each driving test training vehicle needs to be equipped with an instructor and safety officer. Without an instructor and safety officer, it is difficult for students to predict the braking time and brake the vehicle, increasing the risk of driving. Utility Model Content

[0047] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0048] See Figure 1 as well as Figure 7 This utility model discloses a linkage-type secondary brake device, comprising: a drive element 10; a rotating disk 20, the rotating disk 20 being transmittedly connected to the output end of the drive element 10, the drive element 10 driving the rotating disk 20 to rotate, and at least two adjustment mounting positions being provided on the surface of the rotating disk 20; a first rotating connecting arm 30, the first end of the first rotating connecting arm 30 being rotatably connected to the rotating disk 20 at one of the adjustment mounting positions of the rotating disk 20; a second rotating connecting arm 40, the second end of the first rotating connecting arm 30 being rotatably connected to the first end of the second rotating connecting arm 40; and a secondary brake fixing clamp 50, the secondary brake fixing clamp 50 being detachably connected to the secondary brake pedal 60, and the second end of the second rotating connecting arm 40 being rotatably connected to the secondary brake fixing clamp 50.

[0049] The drive element 10 of this invention drives the rotating disk 20 to rotate in the forward direction. The rotating disk 20 drives the auxiliary brake pedal 60 to move downward through the first rotating connecting arm 30, the second rotating connecting arm 40 and the auxiliary brake fixing clamp 50. Thus, the auxiliary brake pedal 60 can be controlled by the drive element 10. Furthermore, the first rotating connecting arm 30 can be adapted to different adjustment and installation positions, and the auxiliary brake fixing clamp 50 can be detachably connected to the auxiliary brake pedal 60. This invention is adjustable and convenient to use.

[0050] It should be noted that the driving element 10 is a motor, and the output end of the driving element 10 is the output shaft of the motor. The output shaft of the motor and the rotation center shaft of the rotating disk 20 are connected by a locking screw 70 or a coupling, so that the driving element 10 drives the rotating disk 20 to rotate.

[0051] When the drive element 10 drives the rotating disk 20 to rotate in the opposite direction, the rotating disk 20 drives the auxiliary brake pedal 60 to move upward through the first rotating connecting arm 30, the second rotating connecting arm 40 and the auxiliary brake fixing clamp 50, thereby resetting the auxiliary brake pedal 60.

[0052] The rotation angle of the rotating disk 20 can be limited by controlling the rotation angle of the output end of the drive element 10, thereby limiting the range of motion of the auxiliary brake pedal 60.

[0053] Rotating disk 20 in the forward direction means rotating disk 20 clockwise, and rotating disk 20 in the reverse direction means rotating disk 20 counterclockwise; or, rotating disk 20 in the forward direction means rotating disk 20 counterclockwise, and rotating disk 20 in the reverse direction means rotating disk 20 clockwise.

[0054] The opening and closing of the drive element 10 can be controlled manually or by using a control module.

[0055] In the case of manual control, when the linkage-type secondary brake device is applied to driving test training vehicles, the instructor can observe the driving speed and distance of the driving test training vehicles from the outside to determine whether it is necessary to open the drive element 10 to drive the secondary brake pedal 60 downward. In this way, the instructor can observe multiple driving test training vehicles and control the drive element 10 on multiple driving test training vehicles, which can save manpower.

[0056] In the case of control module control, when the linkage-type secondary brake device is applied to a driving test training vehicle, a speed sensor for detecting driving speed and a distance sensor for detecting driving distance need to be installed on the driving test training vehicle. Both the speed sensor and the distance sensor transmit the detected data to the control module. The control module determines whether it is necessary to open the drive element 10 to drive the secondary brake pedal 60 downward by comparing the detected data.

[0057] In this embodiment of the utility model, the rotating disk 20 is fan-shaped; the rotating disk 20 is provided with adjustment holes 201 at the adjustment mounting position, and at least two adjustment holes 201 are arranged in an arc shape along the edge of the rotating disk 20.

[0058] Of course, in other embodiments, the rotating disk 20 is provided with an adjustment shaft at the adjustment mounting position, and the rotating disk 20 and the first rotating connecting arm 30 are rotated together by the adjustment shaft.

[0059] For example, see Figure 1 , Figure 2 as well as Figure 4 The rotating disk 20 has five adjustment holes 201 at the adjustment mounting position. These five adjustment holes 201 are evenly spaced in an arc shape along the edge of the rotating disk 20. The arc length span of the five adjustment holes is a1, and the value of a1 ranges from 60° to 150°, with a1 being 100°. The included angle between two adjacent adjustment holes 201 is a2, and the value of a2 ranges from 15° to 30°, with a2 being 25°.

[0060] Therefore, when the first rotating connecting arm 30 is rotatably connected to the adjustment hole 201 at different positions, the installation angle of the first rotating connecting arm 30 can be adjusted.

[0061] It should be noted that, due to the downward or upward movement of the secondary brake pedal 60, the rotation angle of the rotating disc 20 is b, and the value of b ranges from 45° to 80°. For example, see [reference needed]. Figure 7 b = 60°, and the value of b depends on the actual application scenario and is not limited.

[0062] In this embodiment of the utility model, the first rotating connecting arm 30 includes a first screw 301, a second screw 302, and a sleeve 303; the first end of the sleeve 303 is provided with a first threaded hole 304, and the second end of the sleeve 303 is provided with a second threaded hole 305, the threads of the first threaded hole 304 and the second threaded hole 305 are opposite in direction; the first screw 301 is threadedly connected to the first threaded hole 304, and the second screw 302 is threadedly connected to the second threaded hole 305.

[0063] It should be noted that the thread direction of the first screw 301 is compatible with the thread direction of the first threaded hole 304, and the thread direction of the second screw 302 is compatible with the thread direction of the second threaded hole 305. In other words, the thread directions of the first screw 301 and the second screw 302 are opposite.

[0064] When in use, the user rotates the sleeve 303 in the forward direction, so that the first screw 301 and the second screw 302 move closer to each other, and the length of the first rotating connecting arm 30 decreases; the user rotates the sleeve 303 in the reverse direction, so that the first screw 301 and the second screw 302 move further apart, and the length of the first rotating connecting arm 30 increases.

[0065] For example, the length adjustment range of the first rotating connecting arm 30 is 10mm-100mm, and the specific length adjustment range of the first rotating connecting arm 30 is based on not affecting its strength and transmission efficiency.

[0066] Forward rotation of sleeve 303 means rotating sleeve 303 clockwise, and reverse rotation of sleeve 303 means rotating sleeve 303 counterclockwise; or, forward rotation of sleeve 303 means rotating sleeve 303 counterclockwise, and reverse rotation of sleeve 303 means rotating sleeve 303 clockwise.

[0067] In this embodiment of the utility model, the linkage-type secondary brake device also includes a secondary brake pedal 60 and a brake shaft 80 connected to each other. The brake shaft 80 is provided with a protrusion 801 for driving the main brake pedal to move. The secondary brake fixing clamp 50 drives the secondary brake pedal 60 and the brake shaft 80 to rotate together.

[0068] For example, see Figure 7 The driving element 10 drives the rotating disk 20 to rotate clockwise. The rotating disk 20 drives the auxiliary brake pedal 60 and the brake shaft 80 to rotate clockwise around the central axis of the brake shaft 80 through the first rotating connecting arm 30, the second rotating connecting arm 40 and the auxiliary brake fixing clamp 50. That is, the auxiliary brake pedal 60 moves downward.

[0069] When the drive element 10 drives the rotating disk 20 to rotate counterclockwise, the rotating disk 20 drives the auxiliary brake pedal 60 and the brake shaft 80 to rotate counterclockwise around the central axis of the brake shaft 80 through the first rotating connecting arm 30, the second rotating connecting arm 40 and the auxiliary brake fixing clamp 50. That is, the auxiliary brake pedal 60 moves upward.

[0070] For example, this linkage-type secondary brake device is used in driving test training vehicles. The driving test training vehicle is equipped with a main brake pedal, and a return spring is located at the bottom of the main brake pedal. When the secondary brake pedal 60 moves downwards, the protrusion 801 on the brake shaft 80 moves downwards and presses against the main brake pedal, causing the main brake pedal to also move downwards. This brakes the wheels of the driving test training vehicle through the main brake pedal, and at this time, the return spring at the bottom of the main brake pedal is compressed. When the secondary brake pedal 60 moves upwards, the protrusion 801 on the brake shaft 80 moves upwards, separating from the main brake pedal. The main brake pedal returns to its original position under the action of its return spring, thus the main brake pedal no longer brakes the wheels of the driving test training vehicle.

[0071] It should be noted that after the protrusion 801 of the brake shaft 80 separates from the main brake pedal, the protrusion 801 of the brake shaft 80 will not interfere with the movement of the main brake pedal; when the driver presses the main brake pedal to brake the wheels of the driving test training vehicle, when the driver releases the main brake pedal, the main brake pedal will no longer brake the wheels of the driving test training vehicle.

[0072] Specifically, when the master brake pedal moves downward, it pushes the piston to generate pressure in the brake fluid in the master cylinder, thereby braking the wheels. The specific braking principle of the master brake pedal is existing technology and will not be elaborated here.

[0073] In this embodiment of the utility model, the auxiliary brake pedal 60 includes a pedal body 601 and a connecting body 602 connected to each other; the auxiliary brake fixing clip 50 includes a U-shaped body 501, which is sleeved on the outside of the connecting body 602. The opening of the U-shaped body 501 is provided with at least one first connecting hole 502, and a first locking bolt 503 passes through the first connecting hole 502 to lock the U-shaped body 501 and the connecting body 602.

[0074] See Figure 3 as well as Figure 5 The U-shaped body 501 has an opening, and the U-shaped body 501 can be sleeved on the outside of the connecting body 602 through its opening, so that the U-shaped body 501 of the auxiliary brake fixing clamp 50 and the connecting body 602 of the auxiliary brake pedal 60 can be detachably connected.

[0075] Therefore, when the first locking bolt 503 is loosened, the U-shaped body 501 can be fitted onto the connector 602 at different heights. After the U-shaped body 501 is fitted onto the connector 602 at the appropriate position, the first locking bolt 503 is used to lock the U-shaped body 501 and the connector 602.

[0076] Continue reading Figure 1 as well as Figure 5The first connecting hole 502 is a through hole. The first locking bolt 503 passes through the first connecting hole 502 and a first locking nut 504 is fitted on the first locking bolt 503 to lock the U-shaped body 501 and the connecting body 602.

[0077] In this embodiment of the utility model, at least one second connecting hole 505 is provided at the opening position of the U-shaped body 501, and the second locking bolt 506 passes through the second connecting hole 505 to lock the U-shaped body 501 and the connecting body 602; and the end of the second locking bolt 506 is provided with a connecting part 5061, and the second rotating connecting arm 40 is provided with a third connecting hole 401, and the second rotating connecting arm 40 is sleeved on the connecting part 5061 through the third connecting hole 401 to achieve a rotating connection.

[0078] Continue reading Figure 1 as well as Figure 5 The second connecting hole 505 is a through hole. The second locking bolt 506 passes through the second connecting hole 505, and a second locking nut 507 is fitted on the second locking bolt 506 to lock the U-shaped body 501 and the connecting body 602.

[0079] When there are two or more second connecting holes 505, the second locking bolt 506 can be connected to the second connecting holes 505 at different positions as needed to achieve position adjustment of the second rotating connecting arm 40.

[0080] In this embodiment of the utility model, a fourth connecting hole 5062 is provided on the connecting part 5061, and an anti-detachment pin 508 is inserted into the fourth connecting hole 5062.

[0081] Continue reading Figure 5 The second rotating connecting arm 40 is sleeved on the outside of the connecting part 5061 through the third connecting hole 401 to achieve a rotating connection. The anti-detachment pin 508 can prevent the second rotating connecting arm 40 from coming out of the connecting part 5061 of the second locking bolt 506.

[0082] The first end of the first rotating connecting arm 30 is provided with a fifth connecting hole 306, the second end of the first rotating connecting arm 30 is provided with a sixth connecting hole 307, the first end of the second rotating connecting arm 40 is provided with a seventh connecting hole 402, and the second end of the second rotating connecting arm 40 is provided with a third connecting hole 401.

[0083] The first rotating shaft 90 is inserted into the fifth connecting hole 306 and the adjusting hole 201 to realize the rotational connection between the rotating disk 20 and the first rotating connecting arm 30. The second rotating shaft 100 is inserted into the sixth connecting hole 307 and the seventh connecting hole 402 to realize the rotational connection between the first rotating connecting arm 30 and the second rotating connecting arm 40.

[0084] In this embodiment of the utility model, the linkage-type auxiliary brake device further includes a mounting base 110, which includes a first adjusting plate 1101 and a second adjusting plate 1102. The driving element 10 is disposed on the first adjusting plate 1101. The first adjusting plate 1101 is provided with a first adjusting groove 1103, and the second adjusting plate 1102 is provided with a second adjusting groove 1104. A third locking bolt 1105 passes through the first adjusting groove 1103 and the second adjusting groove 1104 to lock the first adjusting plate 1101 and the second adjusting plate 1102.

[0085] It should be noted that the drive element 10 and the first adjustment plate 1101 are connected and fixed together by welding, or the drive element 10 and the first adjustment plate 1101 are locked together by screws.

[0086] When the linkage-type secondary brake device is applied to a driving test training vehicle, the second adjustment plate 1102 is connected and fixed to the frame of the driving test training vehicle by welding, or the second adjustment plate 1102 is locked to the frame of the driving test training vehicle by screws.

[0087] See Figures 1 to 4 The corresponding first adjustment groove 1103 and second adjustment groove 1104 are located at the same height, and the length of the first adjustment groove 1103 is greater than the outer diameter of the third locking bolt 1105, and the length of the second adjustment groove 1104 is greater than the outer diameter of the third locking bolt 1105.

[0088] After adjusting the relative positions of the first adjusting plate 1101 and the second adjusting plate 1102, the third locking bolt 1105 passes through the first adjusting groove 1103 and the second adjusting groove 1104, and a third locking nut 1106 is fitted on the third locking bolt 1105 to lock the first adjusting plate 1101 and the second adjusting plate 1102.

[0089] In this embodiment of the utility model, the linkage-type auxiliary brake device further includes a support frame 120, which includes a first support plate 1201 and a second support plate 1202; the first end of the brake shaft 80 is rotatably connected to the top of the first support plate 1201, the middle part of the brake shaft 80 is rotatably connected to the top of the second support plate 1202, and the protrusion 801 is provided at the second end of the brake shaft 80; the bottom of the first support plate 1201 is provided with a first bending support portion 1203, and the bottom of the second support plate 1202 is provided with a second bending support portion 1204.

[0090] The first support plate 1201 and the second support plate 1202 support the brake shaft 80, so that when the drive element 10 drives the auxiliary brake pedal 60 to move downward through the rotating disk 20, the first rotating connecting arm 30, the second rotating connecting arm 40 and the auxiliary brake fixing clamp 50, the brake shaft 80 can rotate more stably with the auxiliary brake pedal 60.

[0091] In this embodiment of the utility model, the middle part of the first support plate 1201 is sandwiched between the first adjustment plate 1101 and the second adjustment plate 1102.

[0092] Since the brake shaft 80 has a certain length, the first support plate 1201 is clamped by the first adjusting plate 1101 and the second adjusting plate 1102, which helps to improve the support stability of the first support plate 1201 and improves the structural compactness.
