Description
Technical Field
[0001] The utility model relates to the technical field of vehicle pedals, in particular to a telescopic device for a vehicle pedal. Background Art
[0002] For vehicles with high chassis, in order to ensure the safety and convenience of passengers getting on and off the vehicle, pedals are usually installed at the vehicle's boarding and alighting positions for passengers to step on and transition. Currently, the pedals installed on vehicles mainly include fixed pedals and retractable pedals. Among them, the retractable pedals can be extended to the outside of the vehicle body when in use, and can be retracted to the bottom of the vehicle when not in use. The retractable pedals have the advantages of improving the overall appearance of the vehicle, avoiding collisions, high flexibility, ensuring safety and service life, etc., and are therefore widely favored.
[0003] A traditional telescopic vehicle pedal is installed on a fixed bracket through a telescopic bracket. When in use, the telescopic bracket drives the pedal to extend. During the extension process, the telescopic bracket is prone to collide with the fixed bracket. In addition, when in use, at the end of the stroke during the pedal extension process, the pedal often runs too fast (unstable operation), which can easily damage the telescopic bracket and cause problems such as loud noise and pedal shaking, affecting the safety of the occupants' pedaling and the user experience. Utility Model Content
[0004] The utility model aims to provide a telescopic device for a vehicle pedal to solve the problems in the prior art that when the pedal is extended, the telescopic bracket collides with the fixed bracket, and at the end of the stroke during the pedal extension, the pedal often runs too fast and runs unsteadily, which easily damages the telescopic bracket, generates loud noise, and causes the pedal to vibrate, thereby shortening the service life of the telescopic bracket and affecting the passenger's sense of use, pedaling safety, and user experience.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A telescopic device for a vehicle pedal, comprising:
[0007] swing arm assembly, pedal bracket and mounting bracket;
[0008] One end of the swing arm assembly is rotatably mounted on a fixed bracket, and the other end of the swing arm assembly is rotatably mounted on a pedal bracket, and the swing arm assembly can drive the pedal bracket to swing between a retracted position and an extended position;
[0009] A damping member is used to slow down the swinging speed of at least a part of the stroke of the swing arm assembly.
[0010] According to the above-mentioned technical means, by setting a damping member, the swinging speed of the end of the stroke of the swing arm assembly is slowed down during its swinging stroke, so that the pedal bracket can run more smoothly and reduce noise. During specific use, the pedal is installed on the pedal bracket. In the process of the swing arm assembly driving the pedal to swing through the pedal bracket, the damping member slows down the swinging speed of the end of the stroke of the swing arm assembly, so that the pedal can be smoothly extended or retracted, which has the effects of shock absorption, noise reduction and collision prevention, improves the user experience of the passengers, and ensures the safety of the passengers getting on and off the vehicle.
[0011] Furthermore, the damping member is located between the swing arm assembly and the fixing bracket.
[0012] According to the above technical means, the damping member has the function of slowing down the swinging speed of the swing arm assembly at the end of its stroke, so that the pedal bracket can run more smoothly, reduce noise and prevent violent collision between the swing arm assembly and the fixed bracket, causing damage, thereby increasing the service life of the swing arm assembly and the pedal.
[0013] Furthermore, the damping member is mounted on the fixing bracket, and the damping member can abut against the swing arm assembly to slow down the swinging speed of the swing arm assembly.
[0014] According to the above technical means, during specific use, the pedal is installed on the pedal bracket. When the swing arm assembly drives the pedal to swing through the pedal bracket, the swing arm assembly abuts against the damping element, thereby slowing down the swinging speed of the swing arm assembly, so that the pedal can be smoothly extended or retracted. It also has the effect of shock absorption and noise reduction, thereby increasing the service life of the swing arm assembly and the pedal, improving the user experience of the occupants, and ensuring the safety of the occupants' stepping.
[0015] Furthermore, the swing arm assembly includes a first swing arm and a second swing arm, one end of the first swing arm and the second swing arm can be rotatably mounted on a fixed bracket, and the other end of the first swing arm and the second swing arm can be rotatably mounted on a pedal bracket.
[0016] According to the above technical means, the pedal bracket is installed on the fixed bracket through the first swing arm and the second swing arm. When in use, the pedal is installed on the pedal bracket, and the first swing arm and the second swing arm drive the pedal bracket to swing so that the pedal can be smoothly extended and unfolded. The first swing arm and the second swing arm cooperate with each other more firmly, with good stability and higher safety.
[0017] Furthermore, the damping member is located on a side of the second swing arm away from the first swing arm.
[0018] According to the above-mentioned technical means, when in use, during the stroke in which the first swing arm and the second swing arm swing to drive the pedal bracket to extend, the second swing arm abuts against the damping element, thereby reducing the impact force between the second swing arm and the fixed bracket, preventing the pedal bracket from vibrating violently due to the collision between the second swing arm and the fixed bracket, so that the pedal bracket can be extended into place more slowly and steadily with less noise, thereby improving the safety and use experience of the occupants, and extending the service life of the second swing arm.
[0019] Furthermore, the swing arm assembly also includes a buffer component, and the buffer component is installed on a side of the second swing arm close to the first swing arm.
[0020] According to the above technical means, a buffer is provided to mitigate the impact of the first swing arm on the second swing arm when the first swing arm and the second swing arm are swinging, thereby extending the service life of the first swing arm and the second swing arm, reducing the vibration generated between the first swing arm and the second swing arm, and allowing the pedal bracket to be extended and retracted more smoothly.
[0021] Furthermore, when the pedal bracket is in the extended position, one end of the first swing arm close to the pedal bracket abuts against the buffer component; when the pedal bracket is in the retracted position, one end of the first swing arm close to the fixed bracket abuts against the buffer component.
[0022] According to the above-mentioned technical means, during use, when the first swing arm and the second swing arm drive the pedal bracket to be in the extended position, and the end of the first swing arm close to the pedal bracket abuts against the buffer, the first swing arm limits and locks the second swing arm, and the pedal bracket is kept in the unfolded state by the first swing arm to prevent the pedal bracket from being vibrated and folded, thereby causing safety problems. The buffer increases the friction between the end of the first swing arm close to the pedal bracket and the second swing arm while having a buffering effect, and has higher firmness. When the first swing arm and the second swing arm drive the pedal bracket to be in the retracted position, and the end of the first swing arm close to the fixed bracket abuts against the buffer, the buffer has a buffering effect, which reduces the impact force between the first swing arm and the second swing arm, and increases the service life of the first swing arm and the second swing arm. At the same time, the pedal bracket can be retracted smoothly, with low noise and good occupant experience.
[0023] Furthermore, the swing arm assembly also includes a first rotating shaft and a second rotating shaft, one end of the first swing arm is rotatably mounted on the fixed bracket via the first rotating shaft, and the other end is rotatably mounted on the pedal bracket via the second rotating shaft.
[0024] According to the above technical means, the first swing arm is rotatably connected to the fixed bracket and the pedal bracket through the first rotating shaft and the second rotating shaft respectively, which is easy to install and has a simple structure.
[0025] Furthermore, the swing arm assembly also includes a third rotating shaft and a fourth rotating shaft, one end of the second swing arm is rotatably mounted on the fixed bracket via the third rotating shaft, and the other end is rotatably mounted on the pedal bracket via the fourth rotating shaft.
[0026] According to the above technical means, the second swing arm is rotatably connected to the fixed bracket and the pedal bracket through the third rotating shaft and the fourth rotating shaft respectively, which is easy to install and has a simple structure.
[0027] Furthermore, it also includes a driving device, which is drivingly connected to the swing arm assembly and is used to drive the swing arm assembly to swing.
[0028] According to the above technical means, the pedal is installed on the pedal bracket. When in use, the swing arm assembly is driven to swing by the driving device, thereby driving the pedal bracket to swing between the retracted position and the extended position to realize the telescopic function of the pedal. The mechanical automation degree is high and the operation is convenient.
[0029] Furthermore, the damping member and the buffer member are made of rubber.
[0030] According to the above technical means, the rubber material has excellent elasticity and can effectively absorb and disperse the impact force, and has good wear resistance, long service life and low cost.
[0031] Beneficial effects achieved by the utility model:
[0032] The utility model provides a damping member to slow down the swinging speed of the end of the stroke of the swing arm assembly during the swinging stroke, so that the pedal bracket can run smoothly, reduce noise and prevent the swing arm assembly from colliding with the fixed bracket to cause damage. When in use, the pedal is installed on the pedal bracket. In the process of the swing arm assembly driving the pedal to swing through the pedal bracket, the damping member slows down the swinging speed of the end of the stroke of the swing arm assembly, so that the pedal can be smoothly extended or retracted, and the impact force between the swing arm assembly and the fixed bracket is slowed down to prevent the swing arm assembly from being damaged, thereby prolonging the service life of the swing arm assembly and the pedal, and also has the effect of shock absorption and noise reduction, thereby improving the user experience of the occupants and ensuring the safety of the occupants' stepping.

[0045] The technical solution of the present utility model is described in detail below in conjunction with the specific drawings.
[0046] In this embodiment, a telescopic device for a vehicle pedal, such as Figure 1-Figure 4 As shown, it includes: a swing arm assembly 1, a pedal bracket 2 and a fixed bracket 4; one end of the swing arm assembly 1 is rotatably mounted on the fixed bracket 4, and the other end of the swing arm assembly 1 is rotatably mounted on the pedal bracket 2, and the swing arm assembly 1 can drive the pedal bracket 2 to swing between a retracted position and an extended position; a damping member 3, and the damping member 3 is used to slow down the swinging speed of at least part of the stroke of the swing arm assembly 1.
[0047] In this embodiment, the damping member 3 is arranged to slow down the swinging speed at the end of the swing arm assembly 1 during its swinging stroke, so that the pedal bracket 2 can run smoothly, and has the functions of shock absorption, noise reduction and collision prevention. Specifically, when in use, the fixed bracket 4 can be installed on the body of the vehicle, and the pedal can be installed on the pedal bracket 2. The damping member 3 is a rubber block, and the damping member 3 is arranged between the swing arm assembly 1 and the fixed bracket 4. When the pedal needs to be used, the swing arm assembly 1 drives the pedal to swing to the extended position through the pedal bracket 2. During the pedal extension stroke, the rubber block slows down the swinging speed at the end of the swing arm assembly 1, so that the pedal can be extended smoothly, and slows down the impact force between the swing arm assembly 1 and the fixed bracket 4 to prevent damage to the swing arm assembly 1, thereby increasing the service life of the swing arm assembly 1 and the pedal. At the same time, it also has the functions of shock absorption and noise reduction, which improves the user experience of the occupants and ensures the safety of the occupants' stepping. It can be understood by those skilled in the art that the damping member 3 can also be a torsion spring, a spring or other damper, such as a torsion spring installed on the rotating shaft of the swing arm assembly 1. Figure 2As shown, this embodiment is described by taking the pedal bracket 2 in the extended position as an example. It can be understood in the art that the damping member 3 can also be used to mitigate the impact when the pedal bracket 2 is in the retracted position, and it is only necessary to adaptively change the installation position of the damping member 3 on the fixed bracket 4.
[0048] Furthermore, as a preferred embodiment, the damping member 3 is located between the swing arm assembly 1 and the fixed bracket 4; the damping member 3 has the function of slowing down the swinging speed at the end of the swinging stroke of the swing arm assembly 1, so that the pedal bracket 2 can run more smoothly, reduce noise and prevent violent collision between the swing arm assembly 1 and the fixed bracket 4, causing damage, thereby increasing the service life of the swing arm assembly 1 and the pedal.
[0049] In this embodiment, the damping member 3 is mounted on the fixing bracket 4, and the damping member 3 can abut against the swing arm assembly 1 to slow down the swinging speed of the swing arm assembly 1; Figure 2-4 As shown, in the specific use of this embodiment, the pedal is installed on the pedal bracket 2. When the pedal needs to be used, the swing arm assembly 1 drives the pedal to swing to the extended position through the pedal bracket 2. During the pedal extension stroke, the swing arm assembly 1 abuts against the damping element 3, thereby slowing down the swing speed of the swing arm assembly 1, so that the pedal can be smoothly extended or retracted, and it also has the effect of shock absorption and noise reduction, thereby increasing the service life of the swing arm assembly 1 and the pedal, improving the user experience of the occupants, and ensuring the safety of the occupants' stepping.
[0050] In this embodiment, the swing arm assembly 1 includes a first swing arm 11 and a second swing arm 12, one end of the first swing arm 11 and the second swing arm 12 can be rotatably mounted on the fixed bracket 4, and the other end of the first swing arm 11 and the second swing arm 12 can be rotatably mounted on the pedal bracket 2.
[0051] In this embodiment, Figure 1 As shown, the pedal bracket 2 is installed on the fixed bracket 4 by the first swing arm 11 and the second swing arm 12. When in use, the pedal is installed on the pedal bracket 2, and the first swing arm 11 and the second swing arm 12 drive the pedal bracket 2 to swing so that the pedal can be smoothly extended and unfolded. The first swing arm 11 and the second swing arm 12 cooperate with each other to make the connection between the pedal bracket 2 and the fixed bracket 4 more firm, stable and safer.
[0052] In this embodiment, the damping member 3 is located on a side of the second swing arm 12 away from the first swing arm 11; Figure 2As shown, the present embodiment installs the pedal on the pedal bracket 2. When in use, during the stroke in which the first swing arm 11 and the second swing arm 12 swing to drive the pedal bracket 2 to extend, the second swing arm 12 abuts against the damping member 3, thereby reducing the impact force between the second swing arm 12 and the fixed bracket 4, preventing the pedal bracket 2 from vibrating violently due to the impact between the second swing arm 12 and the fixed bracket 4, so that the pedal bracket 2 can drive the pedal to extend into place more slowly and steadily with less noise, thereby improving the safety and usability of the occupants and extending the service life of the second swing arm 12.
[0053] In this embodiment, the swing arm assembly 1 further includes a buffer 13, and the buffer 13 is installed on a side of the second swing arm 12 close to the first swing arm 11; Figure 2-4 As shown, in this embodiment, a buffer member 13 is provided to mitigate the impact of the first swing arm 11 on the second swing arm 12 when the first swing arm 11 and the second swing arm 12 are swinging, thereby extending the service life of the first swing arm 11 and the second swing arm 12, reducing the vibration generated between the first swing arm 11 and the second swing arm 12, and allowing the pedal bracket 2 to extend and retract more smoothly.
[0054] In this embodiment, when the pedal bracket 2 is in the extended position, the end of the first swing arm 11 close to the pedal bracket 2 abuts against the buffer 13; when the pedal bracket 2 is in the retracted position, the end of the first swing arm 11 close to the fixed bracket 4 abuts against the buffer 13.
[0055] In this embodiment, the pedal is mounted on the pedal bracket 2. During use, Figure 2 As shown, when the first swing arm 11 and the second swing arm 12 drive the pedal bracket 2 to be in the extended position, when the end of the first swing arm 11 close to the pedal bracket 2 abuts against the buffer 13, the first swing arm 11 limits and locks the second swing arm 12, and the pedal bracket 2 is kept in the unfolded state by the first swing arm 11 to prevent the pedal bracket 2 from being vibrated and folded, thereby causing safety problems when the occupant steps on it. The buffer 13 not only has a buffering effect, but also increases the friction between the end of the first swing arm 11 close to the pedal bracket 2 and the second swing arm 12, so that the firmness is higher. Figure 3 As shown, when the first swing arm 11 and the second swing arm 12 drive the pedal bracket 2 to be in the retracted position, when the end of the first swing arm 11 close to the fixed bracket 4 abuts against the buffer 13, the buffer 13 has a buffering effect, which reduces the impact force between the first swing arm 11 and the second swing arm 12, and improves the service life of the first swing arm 11 and the second swing arm 12. At the same time, the pedal bracket 2 can be retracted smoothly with low noise and good passenger feel.
[0056] In this embodiment, the swing arm assembly 1 further includes a first rotating shaft 14 and a second rotating shaft 15. One end of the first swing arm 11 is rotatably mounted on the fixed bracket 4 via the first rotating shaft 14, and the other end is rotatably mounted on the pedal bracket 2 via the second rotating shaft 15. Figure 2-4 As shown, the first swing arm 11 is rotatably connected to the fixed bracket 4 and the pedal bracket 2 through the first rotating shaft 14 and the second rotating shaft 15 respectively, which is easy to install and has a simple structure.
[0057] In this embodiment, the swing arm assembly 1 further includes a third rotating shaft 16 and a fourth rotating shaft 17, one end of the second swing arm 12 is rotatably mounted on the fixed bracket 4 via the third rotating shaft 16, and the other end is rotatably mounted on the pedal bracket 2 via the fourth rotating shaft 17; Figure 2-4 As shown, the second swing arm 12 is rotatably connected to the fixed bracket 4 and the pedal bracket 2 through the third rotating shaft 16 and the fourth rotating shaft 17 respectively, which is easy to install and has a simple structure.
[0058] In this embodiment, a driving device 5 is also included, and the driving device 5 is connected to the swing arm assembly 1 for driving the swing arm assembly 1 to swing; Figure 1 As shown, in this embodiment, the pedal is installed on the pedal bracket 2. When in use, the driving device 5 drives the swing arm assembly 1 to swing, thereby driving the pedal bracket 2 to swing between the retracted position and the extended position to realize the telescopic function of the pedal. The mechanical automation level is high and the operation is convenient; the driving device 5 can be a motor or a cylinder.
[0059] Furthermore, as a preferred embodiment, the damping member 3 and the buffer member 13 are made of rubber material, which has good elasticity, low cost and good wear resistance.
[0060] When the present embodiment is used, the fixing bracket 4 can be mounted on the vehicle body, and the pedal can be mounted on the pedal bracket 2. When the pedal is needed, the motor drives the first swing arm 11 and the second swing arm 12 to swing, thereby driving the pedal to swing to the extended position through the pedal bracket 2. At the end of the pedal extension stroke, the second swing arm 12 abuts against the rubber block, thereby slowing down the swinging speed of the second swing arm 12 at the end of the stroke, so that the pedal can be smoothly extended, which has the effects of buffering, shock absorption and noise reduction, and improves the service life of the second swing arm 12, the pedal and the motor gear. When the pedal is in the extended position, the first swing arm One end of 11 close to the pedal bracket 2 abuts against the limiting rubber pad, thereby reducing the impact force between the first swing arm 11 and the second swing arm 12. At the same time, the second swing arm 12 is limited and locked under the action of the first swing arm 11 to ensure that the pedal bracket 2 drives the pedal to be in an expanded state. When the pedal is in the retracted position, one end of the first swing arm 11 close to the fixed bracket 4 abuts against the limiting rubber pad, reducing the impact force between the first swing arm 11 and the second swing arm 12, reducing noise and making the pedal more stable. The pedal is extended and retracted to ensure the safety of the occupant's stepping and extend the service life of the first swing arm 11 and the second swing arm 12.
