[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] The pedal simulator provided in the embodiment of the present application provides resistance through the first elastic member and the second elastic member, so that the driver can feel feedback close to the actual vehicle pedal operation when simulating the pedal operation. Specifically, when the pedal operation is simulated by the pedal simulator, the movement of the piston member causes the first elastic member to be compressed, and when the first elastic member is compressed to a set compression state, the limit member can abut against the piston member to prevent the first elastic member from being over-compressed, and at this time, the deformation of the second elastic member can continue to be used to provide resistance, avoiding the problem of the pedal becoming harder and harder, thereby ensuring the simulation performance and braking effect of the pedal simulator.

[0042] Reference Figure 1 , an embodiment of the present application provides a pedal simulator, the pedal simulator comprising:

[0043] A base 1 and a shell 2, wherein a groove 11 is provided in the base 1, and the shell 2 is buckled on the groove 11;

[0044] The piston member 3, the stopper 4, the first elastic member 5 and the second elastic member 6, at least part of the piston member 3 is movably arranged in the groove 11, the stopper 4 is connected to the piston member 3 through the first elastic member 5, for example, the stopper 4 is connected to the side of the piston member 3 close to the housing 2 through the first elastic member 5, and the second elastic member 6 is arranged between the stopper 4 and the housing 2;

[0045] The limiting member 4 can abut against the piston member 3 to limit the first elastic member 5 to be in a set compression state.

[0046] In this embodiment, the housing 2 is buckled on the groove 11 , and a receiving chamber is formed between the housing 2 and the groove 11 , in which the piston 3 , the limiting member 4 , the first elastic member 5 and the second elastic member 6 are arranged.

[0047] Since the piston member 3 can move in the groove 11, and one end of the first elastic member 5 is connected to or abuts the piston member 3, and the other end of the first elastic member 5 is connected to or abuts the limit member 4; when the piston member 3 moves toward the limit member 4, the piston member 3 can compress the first elastic member 5. Through the compression deformation of the first elastic member 5, the pedal simulator can provide the feel of pedal operation. This stage can be the first simulation stage of the pedal simulator.

[0048] See also Figure 1 When the pedal simulator is in the first simulation stage, a compression gap 100 is formed between the piston member 3 and the limit member 4. When simulating the braking process, the piston member 3 first moves in the direction of reducing the compression gap 100, and then drives the first elastic member 5 to compress upward, and the compression deformation of the first elastic member 5 is used to provide a pedal operation feel.

[0049] When the limit member 4 moves close to the limit member 4 and abuts against the piston member 3, that is, the limit member 4 cannot continue to approach the piston member 3 and compress the first elastic member 5, the limit member 4 is used to seal the first elastic member 5 in the piston member 3, and the first elastic member 5 is limited to be in a set compression state to avoid the first elastic member 5 from being over-compressed; at this time, the compression deformation of the second elastic member 6 can continue to provide resistance to ensure the simulated foot feel of the pedal simulator. This stage can be the second simulation stage of the pedal simulator.

[0050] When the piston 3 contacts the limiting member 4 , the pedal simulator is in the second simulation stage, and the piston 3 and the limiting member 4 will together push the second elastic member 6 to compress, and at this time the second elastic member 6 provides damping.

[0051] It is worth noting that when the pedal simulator is in the first simulation stage, the second elastic member 6 may be compressed or not compressed, and this embodiment of the present application does not limit this.

[0052] The pedal simulator provided in the embodiment of the present application includes a base 1 and a shell 2, wherein a groove 11 is provided in the base 1, and the shell 2 is snapped on the groove 11; a piston member 3, a limit member 4, a first elastic member 5 and a second elastic member 6, wherein the piston member 3 is movably arranged in the groove 11, the limit member 4 is connected to the piston member 3 through the first elastic member 5, and the second elastic member 6 is arranged between the limit member 4 and the shell 2; the limit member 4 can abut against the piston member 3 to limit the first elastic member 5 to be in a set compression state to avoid excessive compression of the first elastic member, and utilizes the deformation of the second elastic member to provide resistance, thereby ensuring the simulation performance and braking effect of the pedal simulator.

[0053] In one embodiment, see Figure 1 and Figure 2 , the limiting member 4 includes a limiting plate 41, and the piston member 3 has an opening 31 facing the limiting member 4;

[0054] When the piston member 3 moves toward the limiting member 4 , the limiting plate 41 can abut against the edge of the opening 31 , so that the first elastic member 5 is in a set compression state.

[0055] In this embodiment, one end of the first elastic member 5 is connected to or abuts the cavity in the piston member 3 through the opening 31, and the other end of the first elastic member 5 is connected to or abuts the limit member 4; the projection of the limit plate 41 on the piston member 3 can cover at least part of the edge of the opening 31 of the piston member 3, so that when the piston member 3 moves closer to the limit member 4, the limit plate 41 can abut against the edge of the opening 31, thereby limiting the first elastic member 5 to be in a set compression state, avoiding excessive compression of the first elastic member 5, and ensuring the simulated foot feel of the pedal simulator.

[0056] In one embodiment, see Figure 1The limiting member 4 includes a clamping portion 42, and the clamping portion 42 is connected to a side of the limiting plate 41 close to the piston member 3;

[0057] A stopper 32 is provided on the piston member 3 , and the stopper 32 is stopped between the clamping portion 42 and the limiting plate 41 .

[0058] In this embodiment, when the first elastic member 5 is connected between the piston member 3 and the limiting member 4, the first elastic member 5 can be first placed into the cavity in the piston member 3 through the opening 31, and then the first elastic member 5 is compressed by the limiting plate 41 and the clamping portion 42 is clamped with the stopping portion 32, so that the clamping portion 42 is stopped in the cavity in the piston member 3 by the stopping portion 32, and the piston member 3, the limiting member 4 and the first elastic member 5 are formed into an integral structure, which is convenient for assembly of the integral structure; at the same time, the limiting member 4 can move in the direction close to the piston member 3, and the limiting member 4 cannot be separated from the piston member 3 in the direction away from the piston member 3.

[0059] In one embodiment, see Figures 1 to 3 The clamping portion 42 includes a plurality of buckles 421, and the plurality of buckles 421 are arranged at intervals on the peripheral side of the limiting plate 41;

[0060] The stopper 32 includes a limiting edge 321 , which is disposed at the opening 31 of the piston member 3 , and the buckle 421 is engaged with the limiting edge 321 for stopping.

[0061] In this embodiment, the limiting edge 321 can be an annular edge at the opening 31 of the piston member 3, and a plurality of buckles 421 can be arranged at equal intervals on the peripheral side of the limiting plate 41, so that when the plurality of buckles 421 cooperate with the stopper of the limiting edge 321, the first elastic member 5 and the piston member 3 are formed into a whole, thereby improving the assembly processability of the pedal simulator and simplifying the installation steps of the pedal simulator, and ensuring the stability of the cooperation between the plurality of buckles 421 and the stopper of the limiting edge 321.

[0062] In this embodiment, since the first elastic member 5 is arranged between the piston member 3 and the limiting member 4, when the buckle 421 cooperates with the stopper of the limiting edge 321, the buckle 421 and the limiting edge 321 are relatively engaged to limit the first elastic member 5 between the limiting member 4 and the piston member 3. On the basis of keeping the first elastic member 5 in a compressed state, the distance between the piston member 3 and the limiting member 4 is prevented from being too large, thereby ensuring the structural integrity of the piston member 3 and the limiting member 4.

[0063] In one embodiment, see Figure 4 The clamping portion 42 includes a connecting column 422, which is disposed on a side of the limiting plate 41 close to the piston member 3, and a clamping protrusion 4221 is disposed on an end of the connecting column 422 away from the limiting plate 41;

[0064] The stopper 32 includes a limiting sleeve 322, which is disposed in the piston member 3, and a limiting block 3221 is disposed inside the limiting sleeve 322;

[0065] The limiting sleeve 322 is sleeved on one end of the connecting column 422 away from the limiting plate 41 , and the clamping protrusion 4221 is engaged with the limiting block 3221 for stopping.

[0066] In this embodiment, when the first elastic member 5 is connected between the piston member 3 and the limiting member 4, the first elastic member 5 can be first placed into the cavity in the piston member 3 through the opening 31, and then the first elastic member 5 is compressed by the limiting plate 41 and the clamping protrusion 4221 is clamped with the limiting block 3221, so that the clamping protrusion 4221 is stopped in the cavity in the piston member 3 by the limiting block 3221, and the piston member 3, the limiting member 4 and the first elastic member 5 are formed into an integral structure, which is convenient for assembly of the integral structure; and the cooperation between the limiting sleeve 322 and the connecting column 422 can improve the connection strength between the piston member 3 and the limiting member 4, and ensure the assembly stability between the piston member 3 and the limiting member 4.

[0067] In this embodiment, since the first elastic member 5 is arranged between the piston member 3 and the limit member 4, when the snap-in protrusion 4221 cooperates with the stopper of the limit block 3221, the snap-in protrusion 4221 and the limit block 3221 are relatively engaged, and the first elastic member 5 is restricted between the limit member 4 and the piston member 3, so that the first elastic member 5 is maintained in a compressed state, avoiding that the distance between the piston member 3 and the limit member 4 is too large, and ensuring the compactness of the structure of the piston member 3 and the limit member 4.

[0068] In one embodiment, see Figure 4 The first elastic member 5 is a coil spring, the connecting column 422 is arranged at the middle position of the limiting plate 41 close to the piston member 3 and the limiting sleeve 322 is penetrated in the coil spring.

[0069] In this embodiment, the first elastic member 5 can be a coil spring made of metal material, a hollow area is formed inside the coil spring, the connecting column 422 and the limiting sleeve 322 are relatively matched, and the connecting column 422 and the limiting sleeve 322 are both inserted into the hollow area in the coil spring to provide guidance for the compression deformation of the first elastic member 5 and avoid displacement of the first elastic member 5 during compression deformation.

[0070] In one embodiment, see Figure 1 and Figure 4 The second elastic member 6 is a rubber spring, and the rubber spring is clamped between the limiting member 4 and the housing 2 .

[0071] In this embodiment, when the limit member 4 moves close to the limit member 4 and abuts against the piston member 3, the limit member 4 is used to seal the first elastic member 5 in the piston member 3 to prevent the first elastic member 5 from being over-compressed. At this time, the resistance can continue to be provided by the compression deformation of the rubber spring. The compression deformation of the rubber spring makes the force value change of the pedal simulator more stable, thereby ensuring the simulated foot feel of the pedal simulator.

[0072] In one embodiment, see Figure 1 and Figure 4 An oil inlet channel 12 is provided on the base 1 , and a side of the piston member 3 away from the housing 2 has a recessed area 33 , and the oil inlet channel 12 is connected to the recessed area 33 .

[0073] In this embodiment, the oil inlet end of the oil inlet channel 12 can be connected to the oil pump, and the oil pump can provide hydraulic oil to the oil inlet channel 12. The pressurized hydraulic oil can push the piston member 3 toward the limit member 4 to achieve compression of the first elastic member 5; and the oil outlet end of the oil inlet channel 12 is connected to the recessed area 33, so that the pressurized hydraulic oil can be delivered to the recessed area 33, and the piston member 3 is pushed to move by the hydraulic oil in the recessed area 33; the recessed area 33 can be an annular area on one side of the piston member 3 away from the shell 2, and the recessed area 33 is used to increase the driving area of ​​the hydraulic oil driving the piston member 3 to move, thereby improving the flexibility and efficiency of the movement of the piston member 3.

[0074] In one embodiment, see Figure 1 and Figure 4 An oil outlet channel 13 is provided on the base 1 , and an inner wall of the groove 11 forms an annular space 111 , which connects the oil outlet channel 13 to the housing 2 .

[0075] In this embodiment, the space inside the shell 2 is connected to the oil outlet channel 13, and oil can be provided in the space inside the shell 2 and the oil outlet channel 13. In the process of the piston member 3 moving toward the limit member 4, the compression gap 100 formed between the piston member 3 and the limit member 4 gradually decreases, and the oil in the compression gap 100 located in the shell 2 can flow out to the outside of the pedal simulator through the oil outlet channel 13; and the annular space 111 connects the oil outlet channel 13 and the space inside the shell 2, which can increase the reflux efficiency of the oil in the compression gap 100 back to the oil outlet channel 13.

[0076] In one embodiment, see Figure 1 The groove 11 forms two step areas at the opening toward the housing 2. The outer opening area is used to connect the housing 2, and the inner opening area is used to set the annular space 111. An assembly gap is formed between the housing 2 and the piston member 3, and the assembly gap connects the compression gap 100 and the annular space 111 to facilitate the connection between the oil outlet channel 13 and the housing 2.

[0077] In one embodiment, see Figure 1 and Figure 4 The pedal simulator also includes a sealing ring 7, which is clamped between the inner wall of the groove 11 and the piston member 3 to avoid cross-flow between the high-pressure hydraulic oil input into the pedal simulator through the oil inlet channel 12 and the low-pressure oil in the housing 2, thereby ensuring the efficiency of the high-pressure hydraulic oil input into the pedal simulator through the oil inlet channel 12 in pushing the piston member 3 to move.

[0078] In one embodiment, see Figure 1 and Figure 4 The inner wall of the groove 11 forms an annular groove 112, which is located between the oil inlet channel 12 and the oil outlet channel 13. The sealing ring 7 is arranged in the annular groove 112 to separate the hydraulic oil in the oil inlet channel 12 from the oil in the oil outlet channel 13.
