Description

Technical Field

[0001] The utility model belongs to the technical field of pedals, in particular to a pedal device and a vehicle. Background Art

[0002] At present, a vehicle pedal device (such as an accelerator pedal or a brake pedal, etc.) is usually composed of a pedal body, a pedal seat, and a spring arranged between the pedal body and the pedal seat. When the driver steps on the pedal body, the pedal body will compress the spring. At this time, the pedal body will feedback the reverse force to the driver under the action of the rebound force of the spring, so that the driver has a pedal feel corresponding to the pedal stepping depth. In the prior art, after the parameters of the spring are selected and its fixed structure is determined, the corresponding relationship between the pedal feel and the pedal stepping depth will be fixed. If the pedal feel needs to be adjusted, the spring with different parameters needs to be replaced. Therefore, the above scheme has the disadvantages of complex pedal feel adjustment operation and long change cycle. Utility Model Content

[0023] Such as Figure 1 And Figure 2As shown, a pedal device provided by the first embodiment of the utility model comprises a driving mechanism 1, an elastic component 2, a first limiting arm 3, a pedal seat 4 and a pedal body 5 rotatably mounted on the pedal seat 4; the elastic component 2 is mounted between the pedal body 5 and the first limiting arm 3; the driving mechanism 1 is mounted on the pedal seat 4 and connected to the first limiting arm 3, and the driving mechanism 1 is used to adjust the initial compression amount of the elastic component 2 through the first limiting arm 3. It can be understood that the elastic component 2 includes but is not limited to a spring, etc., the bottom of the elastic component 2 is fixed on the first limiting arm 3, and the top of the elastic component 2 is in contact with the pedal body 5; the driving mechanism 1 includes but is not limited to a screw nut mechanism, a pneumatic cylinder, a hydraulic cylinder, and a linear motor, etc.

[0024] Specifically, when the driver steps on the pedal body 5, the pedal body 5 rotates around the pedal seat 4, and the pedal body 5 will compress the top of the elastic component 2. By detecting the pedal compression amount of the top of the elastic component 2, the pedal compression amount can be used as a power output signal of the vehicle; and the elastic component 2 has a rebound force on the pedal body 5. As the pedal body 5 is stepped on more deeply, the rebound force of the elastic component 2 on the pedal body 5 will also increase, and the rebound force of the elastic component 2 on the pedal body 5 is fed back to the driver's pedal feel.

[0025] In the utility model, the driving mechanism 1 is installed on the pedal seat 4 and connected to the first limit arm 3, and the elastic component 2 is installed between the pedal body 5 and the first limit arm 3; the driving mechanism 1 drives the first limit arm 3 to move or rotate, and the first limit arm 3 will adjust the initial compression amount of the elastic component 2 from the bottom, so that the initial force of the driver stepping on the pedal body 5 is also different, thereby achieving the purpose of adjusting the pedal force curve. The pedal feel adjustment operation of the pedal device is simple and the adjustment cycle is short. In addition, the pedal device has a simple structure and low manufacturing cost.

[0026] In one embodiment, if Figure 2 As shown, the pedal device further includes a second limiting arm 6, and the first limiting arm 3 and the second limiting arm 6 are both rotatably mounted on the pedal seat 4; the elastic component 2 is mounted between the first limiting arm 3 and the second limiting arm 6, and one end of the second limiting arm 6 away from the elastic component 2 abuts against the pedal body 5. It can be understood that the elastic component 2 is compressed between the first limiting arm 3 and the second limiting arm 6, thereby ensuring the stability of the installation of the elastic component 2.

[0027] Specifically, during the process of stepping on the pedal body 5, the pedal body 5 will drive the second limiting arm 6 to rotate, and the second limiting arm 6 will compress the elastic component 2 from the top. By detecting the rotational offset of the second limiting arm 6, the stepping compression amount at the top of the elastic component 2 can be detected. Additionally, the driving mechanism 1 can drive the first limiting arm 3 to rotate from the bottom, and the first limiting arm 3 will compress the elastic component 2 from the bottom, thereby adjusting the initial compression amount of the elastic component 2.

[0028] In one embodiment, as Figure 2 shown, the driving mechanism 1 includes a slider 11, a driving component 12 installed on the pedal seat 4, and a lead screw 13 connecting the driving component 12; the lead screw 13 is rotatably installed on the pedal seat 4; the slider 11 is provided with a threaded hole, and the lead screw 13 passes through the threaded hole and is threadedly connected to the slider 11; the slider 11 is connected to the first limiting arm 3. It can be understood that the slider 11 can be installed at the bottom of the first limiting arm 3 or can be in contact with the first limiting arm 3; the driving component 12 includes but is not limited to a rotary motor, etc.; the lead screw 13 can be rotatably installed on the pedal seat 4 through a bearing.

[0029] Specifically, the driving component 12 drives the lead screw 13 to rotate, the lead screw 13 drives the slider 11 to move up and down, the slider 11 can drive the first limiting arm 3 to rotate, and the first limiting arm 3 can adjust the initial compression amount of the elastic component 2 from the bottom. In this embodiment, the structure of the driving mechanism 1 is simple and the manufacturing cost is low.

[0030] In one embodiment, the driving mechanism 1 further includes a bearing sleeve 14 and a bearing 15 installed in the bearing sleeve 14, the bearing 15 is sleeved on the lead screw 13, and the bearing sleeve 14 is installed on the pedal seat 4.

[0031] In one embodiment, as Figure 2As shown in the figure, the driving assembly 12 includes a first synchronous pulley 121, a second synchronous pulley 122, a synchronous belt 123, and a rotary driving member 124 mounted on the pedal seat 4. The first synchronous pulley 121 is mounted on the output end of the rotary driving member 124, the second synchronous pulley 122 is mounted on the lead screw 13, and the synchronous belt 123 is sleeved on the first synchronous pulley 121 and the second synchronous pulley 122. It can be understood that the axial direction of the first synchronous pulley 121 is parallel to the axial direction of the second synchronous pulley 122; the rotary driving member 124 includes, but is not limited to, a motor, etc., and the synchronous belt 123 meshes with both the first synchronous pulley 121 and the second synchronous pulley 122 through teeth. Preferably, the outer diameter of the first synchronous pulley 121 is smaller than the outer diameter of the second synchronous pulley 122, so that the first synchronous pulley 121, the synchronous belt 123, and the second synchronous pulley 122 also have the technical effect of reducing speed and increasing torque.

[0032] Specifically, the rotary driving member 124 drives the first synchronous pulley 121 to rotate, and the first synchronous pulley 121 drives the second synchronous pulley 122 and the lead screw 13 to rotate through the synchronous belt 123. In this embodiment, the rotary driving member 124 and the lead screw 13 can be arranged side by side, which improves the compactness of the pedal device and reduces the occupied space of the pedal device.

[0033] In one embodiment, as Figure 2 shown, the pedal device further includes a first sensing assembly. The first sensing assembly includes a first magnetic member 71 mounted on the slider 11 and a first sensor 72 mounted on the pedal seat 4 and disposed opposite to the first magnetic member 71; the first sensor 72 is used to detect the displacement of the first magnetic member 71 when the first magnetic member 71 moves with the slider 11, so as to detect the initial compression amount of the elastic assembly 2 according to the displacement. It can be understood that the first magnetic member 71 can be made of a permanent magnet. Further, the pedal device further includes a first circuit board, the first sensor 72 is integrated on the first circuit board, and the first circuit board is electrically connected to the rotary driving member 124.

[0034] Specifically, the driving assembly 12 drives the slider 11 to move up and down through the lead screw 13. The slider 11 adjusts the initial compression amount of the elastic assembly 2 through the first limiting arm 3. The first sensor 72 can detect the displacement of the slider 11 through the first magnetic member 71, and then obtain the initial compression amount of the elastic assembly 2, ensuring the accuracy of the slider 11 driving the first limiting arm 3 to compress the elastic assembly 2, that is, ensuring the accuracy of the pedal feel adjustment of the pedal assembly.

[0035] In one embodiment, as Figure 2As shown, the pedal device further includes a second sensing component, which includes a second magnetic member 81 mounted on the second limiting arm 6 and a second sensor 82 mounted on the pedal seat 4 and disposed opposite to the second magnetic member 81; the second sensor 82 is used to detect the rotational offset of the second magnetic member 81 when the second magnetic member 81 rotates following the second limiting arm 6. It can be understood that the second magnetic member 81 can be made of a permanent magnet. Further, the pedal device further includes a second circuit board, and the second sensor 82 is integrated on the second circuit board.

[0036] Specifically, during the process that the driver steps on the pedal body 5, the pedal body 5 drives the second limiting arm 6 to rotate, the second limiting arm 6 compresses the elastic component 2 from the top, and the second sensor 82 can detect the rotational offset of the second pressing arm in real time through the second magnetic member 81, and the compression amount of the elastic component 2 during stepping can be obtained through this rotational offset. In this embodiment, the design of the second sensing component improves the intelligent level of the pedal component.

[0037] In one embodiment, the elastic component 2 includes a coaxial inner spring (not shown in the figure) and an outer spring (not shown in the figure); the first ends of the inner spring and the outer spring are in contact with the pedal body 5, and the second ends of the inner spring and the outer spring are in contact with the first limiting arm 3. It can be understood that the inner spring is located inside the outer spring, the first limiting arm 3 can compress the inner spring and the outer spring simultaneously, and the second limiting arm 6 can also compress the inner spring and the outer spring simultaneously. The design of the inner spring and the outer spring improves the rebounding force of the elastic component 2 on the pedal component.

[0038] In one embodiment, the elastic component 2 further includes a vibration isolation sleeve (not shown in the figure) provided with an inner hole; the inner spring and the outer spring have opposite helix directions, the inner spring is installed in the inner hole, and the outer spring is sleeved on the vibration isolation sleeve. It can be understood that the vibration isolation sleeve is made of rubber material. In this embodiment, the outer spring abuts against the outer wall of the vibration isolation sleeve, the inner spring abuts against the inner wall of the vibration isolation sleeve, and the vibration isolation sleeve can reduce the noise and vibration generated during the compression of the inner spring and the outer spring; in addition, the opposite helix directions of the inner spring and the outer spring reduce the friction force between the inner spring, the outer spring and the vibration isolation sleeve during the compression of the inner spring and the outer spring, further ensuring the sound insulation and vibration isolation effects of the elastic component 2.

[0039] In one embodiment, as Figure 2As shown, the pedal base 4 includes a cover plate 41 and a seat body 42 with an internal space. The elastic component 2 and the first limiting arm 3 are both installed in the internal space. The cover plate 41 is detachably installed on the seat body 42 and is used to cover the internal space. It can be understood that the first limiting arm 3 and the second limiting arm 6 are both rotatably installed in the internal space. The opposite ends of the seat body 42 are respectively provided with a first through hole and a second through hole communicating with the internal space. The lead screw 13 passes through the first through hole and extends into the internal space. One end of the second limiting arm 6 far from the elastic component 2 passes through the second through hole and abuts against the pedal assembly. The cover plate 41 and the seat body 42 can be detachably connected through structures such as snaps, screws, bolts, etc. In this embodiment, the detachable design of the cover plate 41 and the seat body 42 facilitates the user to open the internal space and improves the convenience of disassembling and assembling the pedal device.

[0040] In summary, the working principle of the pedal device is as follows: When the user is preparing to drive or during the driving process, if they need the pedal feel style of the pedal device, they can select one of the pre-defined multiple pedal feel styles through a human-machine interface (such as a central control screen, buttons, etc.). After the control software executes the user's instruction, it drives the rotary drive member 124 to perform a corresponding rotary action. The rotation of the rotary drive member 124 will drive the lead screw 13 to rotate through the first synchronous pulley 121, the synchronous belt 123, and the second synchronous pulley 122. The lead screw 13 will drive the slider 11 to rise or fall a certain distance. The slider 11 will adjust the initial compression amount of the elastic component 2 through the first limiting arm 3, thereby adjusting the pedal force curve of the pedal device. At the same time, the first sensor 72 will detect the actual position of the slider 11 (i.e., the bottom of the elastic component 2) through the first magnetic member 71 and feedback it to the software in the controller. The software determines that the slider 11 (i.e., the spring base) has moved to the target position (i.e., the selected pedal feel mode) based on the received position signal, realizing the adjustment of the pedal feel.

[0041] Another embodiment of the present invention also provides a vehicle, including the above-mentioned pedal device.
