Description

Technical Field

[0001] This utility model relates to the field of vehicle braking technology, and in particular to a pedal simulator and a pedal simulator assembly. Background Technology

[0002] With the rapid development of new energy vehicles, automotive automation has received widespread attention from researchers. Drive-by-wire chassis are crucial for the development of automotive automation, as traditional braking technology is increasingly struggling to adapt to this trend. Drive-by-wire technology decouples human power and braking force, particularly evident in electromechanical braking products. The braking system is independently controlled by the electronic power assist unit, and the pedal feel originates solely from the simulator. Therefore, providing the driver with a good braking feel has become a key research focus.

[0003] Existing pedal simulators are mainly located between the pedal base and the pedal arm. Users apply pressure to the pedal arm, and the pedal simulator transmits the pressure to the pedal base to achieve the braking effect. However, in existing "dry" pedal simulators, the pedal damping force is relatively fixed. When the pressure applied by the user to the pedal arm changes, it may significantly affect the vehicle's braking effect after being transmitted through the pedal simulator. This results in a poor pedaling experience for the user under different pressure levels and unstable braking performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor pedaling experience for users under different pedaling forces and unstable braking performance of automobiles, by providing a pedal simulator and a pedal simulator assembly.

[0005] This utility model is achieved through the following technical solution:

[0006] On the one hand, this utility model provides a pedal simulator for connecting a pedal arm and a pedal base, which includes an elastic device and a damping device. The two ends of the elastic device are respectively connected to the pedal arm and the pedal base, and the damping device includes a pressure shaft, a damping cover and a pressure block.

[0007] The pressure shaft is disposed on the elastic device and close to the pedal arm. The end of the pressure shaft away from the pedal arm gradually decreases in radial dimension along the compression direction of the elastic device to form a first inclined surface.

[0008] The damping cover is fixed around the periphery of the elastic device. The pressure block has a second inclined surface that fits against the first inclined surface on its inner periphery, which is perpendicular to the compression direction of the elastic device. The pressure block abuts against the inner wall of the damping cover on its outer periphery, which is perpendicular to the compression direction of the elastic device.

[0009] Furthermore, the angle between the tilting direction of the first inclined surface and the compression direction of the elastic device is between 30 degrees and 60 degrees.

[0010] Furthermore, the damping device also includes a slide block, which is disposed on the elastic device and close to the pedal base. The pressure block is disposed on the slide block, and the distance between the end face of the pressure shaft away from the pedal arm and the slide block is greater than a preset distance.

[0011] Furthermore, the slide has a receiving groove on its end face away from the pedal base, and the distance between the end face of the pressure shaft away from the pedal arm and the bottom of the receiving groove is greater than the preset distance;

[0012] An opening communicating with the receiving groove is provided on the side wall of the slide block, the pressure block is movably disposed in the opening, and the first inclined surface of the pressure shaft and the second inclined surface of the pressure block are in contact with each other in the receiving groove.

[0013] Furthermore, the slide block has an annular groove on its outer sidewall, and the annular groove communicates with the receiving groove at the opening position;

[0014] The damping device also includes a sliding sleeve, which is fitted into the annular groove, and the outer periphery of the pressure block abuts against the inner wall of the damping cover through the sliding sleeve.

[0015] Furthermore, the number of openings on the slide and the number of pressure blocks are both multiple, and the multiple second inclined surfaces of the multiple pressure blocks surround and fit against the first inclined surface.

[0016] Furthermore, the elastic device includes a first elastic element and a second elastic element with the same compression direction. The first end of the first elastic element is connected to the pedal arm, and the second end of the first elastic element abuts against the pressure shaft. The first end of the second elastic element is connected to the pedal base, and the second end of the second elastic element abuts against the slide.

[0017] Furthermore, the elastic device also includes a connecting seat, which is hinged to the pedal arm, and the first end of the first elastic member is sleeved around the connecting seat and abuts against the connecting seat;

[0018] And / or, the elastic device further includes a fixed seat, which is fixedly connected to the damping cover and hinged to the pedal base, and the first end of the second elastic member is sleeved around the fixed seat and abuts against the fixed seat.

[0019] Furthermore, the elastic device also includes a rubber component, and a first fixing groove is provided on the end face of the pressure shaft near the pedal arm. The rubber component is disposed in the first fixing groove and extends out of the end face of the pressure shaft near the pedal arm.

[0020] And / or, a second fixing groove is provided on the end face of the fixing seat away from the pedal base, and the rubber part is disposed in the second fixing groove and extends out of the end face of the fixing seat away from the pedal base.

[0021] On the other hand, the present invention provides a pedal simulator assembly, which includes a pedal arm, a pedal base, and a pedal simulator as described above, wherein the pedal simulator is connected between the pedal arm and the pedal base.

[0022] The beneficial effects of this utility model are:

[0023] The pedal simulator connects the pedal arm and pedal base via an elastic device. The extension and retraction of this device transmits the pedal force from the pedal arm to the pedal base. During compression, the elastic device moves the pressure shaft of the damping device. As the shaft moves, its first inclined surface engages with the second inclined surface of the pressure block, causing the pressure block to press against the inner wall of the damping cover. When the user's pedal force changes, the constant contact between the pressure shaft and the pressure block allows the elastic force of the elastic device to be partially converted into pressure on the pressure block. The contact between the pressure block and the damping cover generates a damping force proportional to the elastic force in the elastic device, ensuring a stable pedaling effect under varying pedaling forces, thus contributing to a more stable braking performance.

Detailed Implementation

[0031] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] like Figure 1 and Figure 3 As shown, this embodiment provides a pedal simulator 2, which is used to connect the pedal arm 1 and the pedal base (not shown in the figure). One end of the overall structure of the pedal simulator 2 is connected to the pedal base, and the other end of the overall structure is connected to the pedal arm 1 through a connecting shaft 11. The pedal arm 1 can be rotated by the pedal shaft 12 fixed to the pedal base. The user can apply a pedaling force to the pedal arm 1, thereby transmitting the pedaling force to the pedal simulator 2 through the connecting shaft 11.

[0033] The pedal simulator 2 includes an elastic device and a damping device. The two ends of the elastic device are connected to the pedal arm 1 and the pedal base, respectively. The damping device includes a pressure shaft 221, a damping cover 222, and a pressure block 223. Specifically, as shown... Figure 2 and Figure 3 As shown, the elastic device of the pedal simulator 2 specifically adopts a first elastic element 211 and a second elastic element 212 that are connected to each other and have the same compression direction. The ends of the first elastic element 211 and the second elastic element 212 that are far apart from each other are respectively connected to the pedal arm 1 and the pedal base, so that the two ends of the elastic device are respectively connected to the pedal arm 1 and the pedal base.

[0034] The pressure shaft 221 and pressure block 223 of the damping device are both mounted on the elastic device. Since the elastic device in this embodiment uses a first elastic element 211 and a second elastic element 212, the pressure shaft 221 and pressure block 223 of the damping device are both located at the connection position of the first elastic element 211 and the second elastic element 212. The pressure shaft 221 is close to the pedal arm 1 on the elastic device, and the radial dimension of the end of the pressure shaft 221 away from the pedal arm 1 gradually decreases along the compression direction H of the elastic device to form a first inclined surface 2211. The overall structure of the damping cover 222 is similar to a cylindrical structure. The damping cover 222 is fixed around the periphery of the elastic device. The pressure block 223 has a second inclined surface 2231 that fits against the first inclined surface 2211 on its inner periphery in the compression direction H perpendicular to the elastic device. The outer periphery of the pressure block 223 in the compression direction H perpendicular to the elastic device abuts against the inner wall of the damping cover 222.

[0035] With the above configuration, the pedal simulator 2 connects the pedal arm 1 and the pedal base via an elastic device. The compression of the elastic device transmits the pedaling force from the pedal arm 1 to the pedal base. During compression, the elastic device drives the pressure shaft 221 of the damping device to move. As the pressure shaft 221 moves, its first inclined surface 2211 contacts the second inclined surface 2231 of the pressure block 223, causing the pressure block 223 to abut against the inner wall of the damping cover 222. When the user's pedaling force changes, the constant contact between the pressure shaft 221 and the pressure block 223 allows the elastic force of the elastic device to be partially converted into pressure pressing the pressure block 223. The contact between the pressure block 223 and the damping cover 222 generates a damping force proportional to the elastic force in the elastic device, ensuring a relatively stable pedaling effect under different pedaling forces. Furthermore, when the user releases the pedal arm 1, the direction of this damping force changes, causing a lag in the movement of the damping device, thus ensuring a more stable reset of the entire pedal simulator 2.

[0036] It should be noted that in this embodiment, the elastic device uses a first elastic element 211 and a second elastic element 212 that are interconnected and have the same compression direction. This makes it easier to place components such as the pressure shaft 221 and the pressure block 223 in the damping device between the first elastic element 211 and the second elastic element 212, so that the elastic device can drive the pressure shaft 221 and the pressure block 223 in the damping device to move during compression. However, in other alternative embodiments, other elastic devices existing in the prior art can also be used, as long as they can satisfy the requirement of placing the pressure shaft 221 and the pressure block 223 in the damping device on the elastic device and being able to move with the compression of the elastic device.

[0037] like Figure 1 and Figure 2As shown, the radial dimension of the pressure shaft 221 gradually decreases along the compression direction H of the elastic device at the end away from the pedal arm 1, forming a first inclined surface 2211. Through the arrangement of this first inclined surface 2211, the end of the pressure shaft 221 is formed into a structure similar to a frustum of a cone, and the angle between the inclination direction of the first inclined surface 2211 and the compression direction H of the elastic device ranges from 30 degrees to 60 degrees. By setting the included angle within this range, the ratio between damping force and elastic force can be kept within a suitable range. If the included angle is too large, when the second inclined surface 2231 of the pressure block 223 is in contact with the first inclined surface 2211, the elastic force on the pressure shaft 221 will act more along the compression direction H of the elastic device on the pressure block 223, thus making the damping force formed between the pressure block 223 and the damping cover 222 less affected by the elastic force. Similarly, if the included angle is small, when the second inclined surface 2231 of the pressure block 223 is in contact with the first inclined surface 2211, the elastic force on the pressure shaft 221 will act more along the compression direction H perpendicular to the elastic device on the pressure block 223, thus making the damping force formed between the pressure block 223 and the damping cover 222 more affected by the elastic force. Therefore, setting the angle between the tilting direction of the first inclined surface 2211 and the compression direction H of the elastic device within the range of 30 degrees to 60 degrees can better avoid the ratio between damping force and elastic force being too large or too small, and further improve the stability of the pedaling effect under different pedaling forces.

[0038] Combination Figure 4 and Figure 5 As shown, the damping device also includes a slide 224, which is also disposed on the elastic device, specifically between the first elastic element 211 and the second elastic element 212. The slide 224 is located close to the pedal base on the elastic device. The pressure block 223 is disposed on the slide 224, and the distance between the end face of the pressure shaft 221 away from the pedal arm 1 and the slide 224 is greater than a preset distance. By disposing of the slide 224 on the side of the elastic device close to the pedal base to hold the pressure block 223, the pressure block 223 can better bear the force applied by the pressure shaft 221. Furthermore, the distance between the end face of the pressure shaft 221 away from the pedal arm 1 and the slide 224 is set to be greater than a preset distance, i.e., a certain gap is provided between the pressure shaft 221 and the slide 224. This prevents the pressure shaft 221 from applying the elastic force of the elastic device to the slide 224, but only to the pressure block 223. This allows the pressure block 223 to better form a damping force that varies proportionally with the elastic force between itself and the damping cover 222. In the specific settings, the preset distance can be adjusted according to the actual situation. However, it is clear that even when the preset distance is set to zero, the distance between the end face of the pressure shaft 221 away from the pedal arm 1 and the slide 224 is greater than zero. That is, there is still a certain gap between the end face of the pressure shaft 221 away from the pedal arm 1 and the slide 224.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, a receiving groove 2241 is provided on the end face of the slide 224 away from the pedal base. The distance between the end face of the pressure shaft 221 away from the pedal arm 1 and the bottom of the receiving groove 2241 is greater than a preset distance. An opening 2242 communicating with the receiving groove 2241 is provided on the side wall of the slide 224. The pressure block 223 is movably disposed in the opening 2242, and the first inclined surface 2211 of the pressure shaft 221 and the second inclined surface 2231 of the pressure block 223 are in contact with each other in the receiving groove 2241. With this structural arrangement of the slide 224, the end of the pressure shaft 221 with the first inclined surface 2211 can be accommodated in the receiving groove 2241 along the axial direction of the slide 224, while the pressure block 223 is arranged in the opening 2242 on the side wall of the slide 224. That is, the pressure block 223 is movably arranged on the slide 224 along the radial direction of the slide 224. The first inclined surface 2211 of the pressure shaft 221 is attached to the second inclined surface 2231 in the receiving groove 2241, so that the axial force of the pressure shaft 221 along the slide 224 can be directly converted into the radial force of the pressure block 223, thus making it easier to form a damping force that changes proportionally with the elastic force. The structure of the entire pedal simulator 2 is also more reasonable and compact.

[0040] Furthermore, the slide block 224 has an annular groove 2243 on its outer sidewall. The annular groove 2243 communicates with the receiving groove 2241 at the opening 2242. The damping device also includes a sliding sleeve 225, which fits in the annular groove 2243. The outer periphery of the pressure block 223 abuts against the inner wall of the damping cover 222 through the sliding sleeve 225. With this arrangement, when the pressure block 223 is subjected to the force transmitted by the pressure shaft 221, it can act on the damping cover 222 through the sliding sleeve 225. Thus, different materials of the sliding sleeve 225 can be selected according to actual needs, thereby satisfying the formation of a more suitable damping force between the pressure block 223 and the damping cover 222. At the same time, under long-term use of the pedal simulator 2, the sliding sleeve 225 can also be used for wear compensation, avoiding direct wear between the pressure block 223 and the damping cover 222. When the wear is severe, the sliding sleeve 225 can be directly replaced, improving the overall reliability of the pedal simulator 2.

[0041] like Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, the number of openings 2242 and pressure blocks 223 on the slide 224 are both set to three. Each pressure block 223 has three second inclined surfaces 2231, which are arranged in a circular array around and attached to the first inclined surface 2211. With this arrangement, a single pressure shaft 221 can simultaneously apply force to multiple pressure blocks 223, allowing them to simultaneously cooperate with the damping cover 222 to form damping force. Furthermore, the circular arrangement of the pressure blocks 223 ensures a more uniform damping force, further improving the stability of the pedaling effect under different pedaling forces. Of course, in other alternative embodiments, the number of openings 2242 and pressure blocks 223 on the slide 224 can be adjusted according to actual conditions and are not fixed.

[0042] As mentioned above, in this embodiment, the elastic device includes a first elastic element 211 and a second elastic element 212 that are interconnected and have the same compression direction. Figure 1 As shown, the first end of the first elastic element 211 is connected to the pedal arm 1, and the second end of the first elastic element 211 abuts against the pressure shaft 221. The first end of the second elastic element 212 is connected to the pedal base, and the second end of the second elastic element 212 abuts against the slide block 224. When the user applies a pedaling force to the pedal arm 1, the force can first be transmitted to the damping device through the first elastic element 211 to quickly form a damping force proportional to the elastic force. Then, the force is finally applied to the pedal base through the second elastic element 212, ultimately forming a stable pedaling effect.

[0043] It should be noted that in this embodiment, both the first elastic element 211 and the second elastic element 212 are compression springs. In specific configurations, compression springs with suitable elastic coefficients can be selected according to actual needs. However, in other alternative embodiments, the first elastic element 211 and the second elastic element 212 can also be other elastic elements existing in the prior art, without any fixed limitations.

[0044] Furthermore, such as Figure 1 and Figure 3As shown, the elastic device also includes a connecting seat 213, which is hinged to the pedal arm 1. The first end of the first elastic element 211 is sleeved around the connecting seat 213 and abuts against it. The connecting seat 213 ensures a more stable connection and movement between the first elastic element 211 and the pedal arm 1. Furthermore, when the user applies a pedaling force to the pedal arm 1, the first elastic element 211 maintains linear compression under force, resulting in a more reasonable force distribution on the entire pedal simulator 2. Similarly, the elastic device also includes a fixed seat 214, which is fixedly connected to the damping cover 222 and hinged to the pedal base. The first end of the second elastic element 212 is sleeved around the fixed seat 214 and abuts against it. The fixed seat 214 also ensures a more stable connection and movement between the second elastic element 212 and the pedal arm 1. Additionally, the second elastic element 212 maintains linear compression under force, further improving the overall force distribution on the pedal simulator 2.

[0045] In addition, such as Figure 1 and Figure 3 As shown, the elastic device also includes rubber components, which include a first rubber component 215 and a second rubber component 216. The pressure shaft 221 has a first fixing groove on its end face near the pedal arm 1. The first rubber component 215 is disposed in the first fixing groove and extends out of the pressure shaft 221 near the end face of the pedal arm 1. When the first elastic component 211 is compressed to a certain stroke, the bottom surface of the connecting seat 213 will contact and compress the first rubber component 215 until the bottom surface of the connecting seat 213 is in contact with the upper end face of the pressure shaft 221. Thus, the connecting seat 213 directly applies force to the pressure shaft 221, which more directly and effectively drives the pressure shaft 221 to move, thereby transmitting the force to the pressure block 223, and thus more effectively increasing the stroke damping force. In addition, a second fixing groove is provided on the end face of the fixed seat 214 away from the pedal base. The second rubber part 216 is disposed in the second fixing groove and extends out of the end face of the fixed seat 214 away from the pedal base. When the pedal arm 1 further compresses the pedal simulator 2, the slide 224 moves along the damping cover 222 until the lower surface of the slide 224 contacts and compresses the second rubber part 216, until the lower surface of the slide 224 makes hard contact with the upper surface of the fixed seat 214, which plays a limiting role. In this state, the entire pedal compression stroke reaches its maximum.

[0046] This embodiment also provides a pedal simulator assembly, which includes a pedal arm 1, a pedal base, and a pedal simulator 2 as described above, with the pedal simulator 2 connected between the pedal arm 1 and the pedal base. Therefore, when this pedal simulator assembly is applied to a car, the user's pedaling experience is relatively better under different pedaling forces, and the car's braking effect is also relatively more stable.

[0047] The above description is a preferred embodiment of the present utility model, and the technical solution of the present utility model has been further described in detail. It is not intended to limit the protection scope of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications are also considered to be within the protection scope of the present utility model.
