Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a vehicle pedal drive structure. Background Technology

[0002] In modern automotive manufacturing, pedals, as a crucial operating device, directly impact driving safety and the driver's experience through their stability and durability. The pedal drive motor, a key component of the pedal system, is responsible for driving the pedal's extension, retraction, and adjustment; its performance and reliability are paramount. However, currently, most vehicle pedal drive motors are mounted externally. This design often makes the motor prone to damage, leading to a series of safety issues. When exposed to the external environment, the motor is more susceptible to dust, dirt, and harsh weather conditions. For example, it can be struck by flying stones during driving, causing impacts and damage. Furthermore, in rainy weather, the exposed motor is vulnerable to water corrosion. Moisture entering the motor can cause rust or short circuits, accelerating wear and aging, shortening its lifespan, and leading to malfunctions. This necessitates frequent maintenance or replacement, increasing maintenance costs and hindering economic efficiency.

[0003] Therefore, a drive structure that hides the motor inside the pedal is needed to drive the pedal, in order to enhance the service life of the pedal motor, reduce maintenance frequency, and improve economy. Utility Model Content

[0004] This utility model provides a vehicle pedal drive structure to solve the problem that the motor is exposed to the outside of the vehicle body and will be damaged during the pedal extension and retraction process, thereby reducing the maintenance frequency of the pedal.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vehicle pedal drive structure includes: a pedal and a swing assembly, the swing assembly being mounted on the bottom of a vehicle body, the pedal being mounted on the swing assembly; the swing assembly being configured to drive the pedal to extend or retract from the bottom of the vehicle body; and a motor, the motor being mounted inside the pedal and configured to drive the swing assembly to swing.

[0007] According to the above technical means, the motor is installed in the pedal to avoid damage to the motor caused by flying stone particles during vehicle operation, thereby extending the service life of the motor and reducing maintenance costs; the motor is driven to the swing component, ensuring the rapid response and stability of the swing component, and the motor can provide a continuous and stable driving force to the pedal. When the motor starts or stops, the swing component can swing or stop swinging with the start or stop of the motor.

[0008] Furthermore, installing the motor inside the pedal makes the pedal structure compact, reduces space occupation, and frees up space for the installation of other components under the vehicle.

[0009] Furthermore, a first mounting groove is formed on the pedal, and the motor is mounted in the first mounting groove.

[0010] According to the above technical means, the first mounting slot provides precise positioning and installation guidance for the motor, and the motor is hidden inside the pedal by the first mounting slot, so as to avoid the motor being exposed to the outside of the pedal and being damaged by flying stone particles, thereby extending the service life of the motor and ensuring the normal use of the motor.

[0011] Furthermore, a second mounting groove is formed on the pedal, and the swing assembly is installed in the second mounting groove; the first mounting groove is formed on the side wall of the second mounting groove.

[0012] According to the above technical means, the second mounting groove provides precise positioning and installation guidance for the fixing frame, making installation convenient; the first mounting groove is formed on the side wall of the second mounting groove, which makes it easy to hide the motor inside the pedal, optimizes the spatial layout of the pedal, makes the pedal structure compact, and improves space utilization.

[0013] Furthermore, the swing assembly includes a fixed frame, a first swing arm, a second swing arm, and a connecting arm, with the pedal mounted on the fixed frame; one end of the first swing arm and one end of the second swing arm are rotatably mounted on the fixed frame; the other end of the first swing arm and the other end of the second swing arm are rotatably mounted on the connecting arm; the connecting arm is used to mount on the bottom of the vehicle body.

[0014] According to the above technical means, the fixed frame, the first swing arm, the second swing arm and the connecting arm together form a four-bar linkage structure, which has high flexibility when driven by the motor. This allows the fixed frame to be adjusted by the motor relative to the first swing arm via the drive shaft, and further adjusts the position of the fixed frame relative to the connecting arm, so that the pedal can extend or retract to the bottom of the vehicle body, thus achieving effective torque transmission.

[0015] Furthermore, it also includes a drive shaft, which is fixedly connected to one end of the first swing arm; the motor is driven by the drive shaft to drive the drive shaft to rotate.

[0016] According to the above technical means, the motor and the first swing arm are connected by the drive shaft, so as to continuously and stably transmit the power of the motor to the first swing arm to drive the first swing arm to swing.

[0017] Furthermore, the fixing frame includes a first side arm and two second side arms, with one end of each of the two second side arms respectively mounted on both ends of the first side arm; one end of the first swing arm is rotatably mounted between the two second side arms and located at the other end of the two second side arms; one end of the second swing arm is rotatably mounted between the two second side arms.

[0018] According to the above technical means, the first side arm and the two second side arms form a stable installation structure. When the first swing arm and the second swing arm are installed between the two second side arms, they are not easy to fall off, which increases the installation stability of the first swing arm and the second swing arm and further increases the service life of the swing assembly.

[0019] Furthermore, the swing assembly also includes a first pivot, and a first through hole is formed at one end of the second swing arm; the first pivot passes through the first through hole, and its two ends are respectively mounted on the two second side arms.

[0020] According to the above technical means, the first rotating shaft supports and limits the second swing arm and the two second side arms, preventing the second swing arm from falling off between the two second side arms during the swing process, and increasing the connection stability between the second swing arm and the second side arms; at the same time, the first rotating shaft can reduce the friction and resistance when the second swing arm swings, so that the second swing arm can swing smoothly relative to the second side arms.

[0021] Furthermore, the swing assembly also includes a second pivot and a third pivot. A second through hole is formed at the other end of the second swing arm, the second pivot passes through the second through hole, and its end is installed at one end of the connecting arm. A third through hole is formed at the other end of the first swing arm, the third pivot passes through the third through hole, and its end is installed at the other end of the connecting arm.

[0022] According to the above technical means, the second pivot provides a stable connection and limit for the second swing arm and the connecting arm, preventing the second swing arm and the connecting arm from detaching, increasing the connection stability between the second swing arm and the connecting arm, and the second pivot can also reduce the friction between the second swing arm and the connecting arm during swinging; similarly, the third pivot provides a stable connection and limit for the first swing arm and the connecting arm, preventing the first swing arm and the connecting arm from detaching, increasing the connection stability between the second swing arm and the connecting arm, and the third pivot can also reduce the friction between the first swing arm and the connecting arm during swinging, further enabling the swing assembly to smoothly drive the pedal to extend or retract to the bottom of the vehicle body.

[0023] Furthermore, there are two sets of swing components and one motor. The motor is connected to one set of swing components to drive one set of swing components to swing, which in turn drives the other set of swing components to swing, so that the pedal can extend or retract to the bottom of the vehicle body.

[0024] According to the above-mentioned technical means, the motor drives a group of swing components to swing, thereby driving another group of swing components to swing synchronously. This effectively utilizes the power of the motor, ensuring that the swing components respond quickly and swing stably. Setting up one motor can leave extra installation space for other parts at the bottom of the vehicle body, which is beneficial to optimizing the vehicle's installation space and reducing the manufacturing cost of the pedal.

[0025] Furthermore, there are two sets of swing components and two motors. Each of the two motors is connected to one set of swing components to drive the two sets of swing components synchronously to extend or retract the pedal to the bottom of the vehicle body.

[0026] According to the above technical means, by synchronously driving the two swing components with two motors, the swing components can be ensured to respond quickly and swing stably. When one motor fails to work properly, the other motor can drive the pedal to rotate, thereby improving the practicality and reliability of the pedal.

[0027] Beneficial effects:

[0028] 1. The gearbox assembly of the motor is installed inside the pedal to prevent the motor from being damaged by flying stone particles during vehicle operation, thereby extending the service life of the motor and reducing maintenance costs; the motor is driven by the swing assembly, ensuring the rapid response and stability of the swing assembly, while the motor can provide a continuous and stable driving force to the pedal. When the motor starts or stops, the swing assembly can swing or stop swinging with the start or stop of the motor.

[0029] 2. Installing the motor inside the pedal makes the pedal structure compact, reduces space occupation, and frees up space for the installation of other components under the vehicle. Attached Figure Description

[0043] Example 1

[0044] like Figures 1 to 4As shown, a vehicle pedal 100 drive structure includes: a pedal 100 and a swing assembly 200, the swing assembly 200 being mounted on the bottom of the vehicle body, the pedal 100 being mounted on the swing assembly 200; the swing assembly 200 being configured to drive the pedal 100 to extend or retract from the bottom of the vehicle body; and a motor 300, the motor 300 being mounted inside the pedal 100 and configured to drive the swing assembly 200 to swing.

[0045] According to the above technical means, the motor 300 is installed in the pedal 100 to avoid damage to the motor 300 caused by the collision of flying stone particles during vehicle operation, thereby extending the service life of the motor 300 and reducing maintenance costs. The motor 300 is driven by the swing component 200, ensuring the rapid response and stability of the swing component 200. At the same time, the motor 300 can provide a continuous and stable driving force to the pedal 100. When the motor 300 starts or stops, the swing component 200 can swing or stop swinging with the start or stop of the motor 300.

[0046] In addition, by installing the motor 300 inside the pedal 100, the structure of the pedal 100 becomes compact, reducing space occupation and freeing up space for the installation of other components under the vehicle.

[0047] like Figure 2 As shown, a first mounting groove 110 is formed on the pedal 100, and the motor 300 is installed in the first mounting groove 110. The first mounting groove 110 provides precise positioning and installation guidance for the motor 300, and the motor 300 is hidden inside the pedal 100 by the first mounting groove 110, avoiding damage to the motor 300 caused by the impact of flying stone particles when exposed outside the pedal 100, thereby extending the service life of the motor 300 and ensuring the normal use of the motor 300.

[0048] like Figure 2 As shown, in this embodiment, a second mounting groove 120 is formed on the pedal 100, and the swing assembly 200 is installed in the second mounting groove 120; a first mounting groove 110 is formed on the side wall of the second mounting groove 120. The second mounting groove 120 provides precise positioning and installation guidance for the fixing bracket 210, making installation convenient; the first mounting groove 110 being formed on the side wall of the second mounting groove 120 facilitates hiding the motor 300 inside the pedal 100, optimizing the spatial layout of the pedal 100, making the pedal 100 structure compact, and improving space utilization.

[0049] In other embodiments, the second mounting groove 120 may not be formed on the pedal 100.

[0050] like Figure 3As shown, in this embodiment, the swing assembly 200 includes a fixed frame 210, a first swing arm 220, a second swing arm 230, and a connecting arm 240. The pedal 100 is mounted on the fixed frame 210. One end of the first swing arm 220 and one end of the second swing arm 230 are rotatably mounted on the fixed frame 210. The other end of the first swing arm 220 and the other end of the second swing arm 230 are rotatably mounted on the connecting arm 240. The connecting arm 240 is used to mount on the bottom of the vehicle body. The fixed frame 210, the first swing arm 220, the second swing arm 230, and the connecting arm 240 together form a four-bar linkage structure, which has high flexibility when driven by the motor 300. This allows the fixed frame 210 to be adjusted by the motor 300 via the drive shaft 400 to swing at an angle relative to the first swing arm 220, and further adjust the position of the fixed frame 210 relative to the connecting arm 240, so that the pedal 100 can extend or retract to the bottom of the vehicle body, achieving effective torque transmission.

[0051] like Figure 3 As shown, this embodiment also includes a drive shaft 400, which is fixedly connected to one end of the first swing arm 220; a motor 300 is driven to the drive shaft 400 to drive the drive shaft 400 to rotate. By using the drive shaft 400 to drive the motor 300 and the first swing arm 220, the power of the motor 300 is continuously and stably transmitted to the first swing arm 220 to drive the first swing arm 220 to swing.

[0052] like Figure 3 As shown, in this embodiment, the fixing frame 210 includes a first side arm 211 and two second side arms 212, with one end of each of the two second side arms 212 respectively mounted at both ends of the first side arm 211; one end of a first swing arm 220 is rotatably mounted between the two second side arms 212 and located at the other end of the two second side arms 212; one end of a second swing arm 230 is rotatably mounted between the two second side arms 212. The first side arm 211 and the two second side arms 212 form a stable mounting structure, and the first swing arm 220 and the second swing arm 230 are not easily detached when mounted between the two second side arms 212, increasing the installation stability of the first swing arm 220 and the second swing arm 230, and further increasing the service life of the swing assembly 200.

[0053] like Figure 3As shown, in this embodiment, the swing assembly 200 further includes a first rotating shaft 250, and a first through hole 231 is formed at one end of the second swing arm 230; the first rotating shaft 250 passes through the first through hole 231, and its two ends are respectively mounted on the two second side arms 212. The first rotating shaft 250 supports and limits the second swing arm 230 and the two second side arms 212, preventing the second swing arm 230 from falling off between the two second side arms 212 during the swinging process, and increasing the connection stability between the second swing arm 230 and the second side arms 212; at the same time, the first rotating shaft 250 can reduce the friction and resistance when the second swing arm 230 swings, so that the second swing arm 230 can swing smoothly relative to the second side arms 212.

[0054] like Figure 3 As shown, in this embodiment, the swing assembly 200 further includes a second rotating shaft 260 and a third rotating shaft 270. A second through hole 232 is formed at the other end of the second swing arm 230. The second rotating shaft 260 passes through the second through hole 232 and its end is installed at one end of the connecting arm 240. A third through hole 221 is formed at the other end of the first swing arm 220. The third rotating shaft 270 passes through the third through hole 221 and its end is installed at the other end of the connecting arm 240. The second pivot 260 provides a stable connection and limit for the second swing arm 230 and the connecting arm 240, preventing the second swing arm 230 and the connecting arm 240 from detaching, thus increasing the connection stability between the second swing arm 230 and the connecting arm 240. The second pivot 260 can also reduce the friction between the second swing arm 230 and the connecting arm 240 during swinging. Similarly, the third pivot 270 provides a stable connection and limit for the first swing arm 220 and the connecting arm 240, preventing the first swing arm 220 and the connecting arm 240 from detaching, thus increasing the connection stability between the second swing arm 230 and the connecting arm 240. The third pivot 270 can also reduce the friction between the first swing arm 220 and the connecting arm 240 during swinging, further enabling the swing assembly 200 to smoothly drive the pedal 100 to extend or retract to the bottom of the vehicle body.

[0055] Preferably, a fourth through hole 222 is formed at the end of the first swing arm 220 away from the third through hole 221, and the other end of the drive shaft 400 passes through one second side arm 212 and the fourth through hole 222 in sequence before being mounted on another second side arm 212. It is worth mentioning that through holes are also formed on one or both second side arms 212 so that the drive shaft 400 can pass through.

[0056] Preferably, such as Figure 3As shown, in this embodiment, the first swing arm 220 and the second swing arm 230 are connected by two connecting arms 240. The two ends of the second rotating shaft 260 are respectively mounted on one end of each of the two connecting arms 240; the two ends of the third rotating shaft 270 are respectively mounted on the other end of each of the two connecting arms 240. The two connecting arms 240 increase the overall stability of the swing assembly 200, and also increase the stability of the swing assembly 200 mounted on the bottom of the vehicle body. It is worth mentioning that in this embodiment, the first swing arm 220 and the second swing arm 230 are mounted between the two connecting arms 240.

[0057] like Figure 2 As shown, in this embodiment, there are two sets of swing components 200 and one motor 300. The motor 300 is driven by one set of swing components 200 to drive the swing components 200 to swing, which in turn drives the other set of swing components 200 to swing, so that the pedal 100 can extend or retract from the bottom of the vehicle body. By driving one set of swing components 200 to swing, and then driving the other set of swing components 200 to swing synchronously, the power of the motor 300 is effectively utilized, ensuring that the swing components 200 respond quickly and swing stably. Setting up one motor 300 can leave extra installation space for other components at the bottom of the vehicle body, which is beneficial to optimizing the vehicle's installation space and reducing the manufacturing cost of the pedal 100. Correspondingly, two second mounting slots 120 are formed on the pedal 100, and the inner wall of one of the second mounting slots 120 forms a first mounting slot 110 so that a motor 300 can be installed in the first mounting slot 110.

[0058] Example 2

[0059] like Figure 5 As shown, in this embodiment, there are two sets of swing components 200 and two motors 300. Each motor 300 is connected to one set of swing components 200 to drive the two sets of swing components 200 synchronously, causing the pedal 100 to extend or retract to the bottom of the vehicle body. By having the two motors 300 synchronously drive the two swing components 200 to swing synchronously, it ensures that the swing components 200 can respond quickly and swing stably. Furthermore, when one motor 300 fails to function properly, the other motor 300 can drive the pedal 100 to rotate, improving the practicality and reliability of the pedal 100. Correspondingly, two second mounting slots 120 are formed on the pedal 100, and the inner walls of both second mounting slots 120 are formed with first mounting slots 110, so that the two motors 300 can be installed in the two first mounting slots 110 respectively.

[0060] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
