[0034] The embodiments of the present application provide a vehicle, it should be noted that the vehicle in the present application can refer to a large car, a small car, a special car, etc. For example, according to the vehicle type, the vehicle in the present application can be a sedan type, a SUV type, a Multi-Purpose Vehicles (MPV) type or other types. For the vehicle, a pedal assembly is generally provided, which includes a pedal and a pedal adjusting structure 10. The pedal is a brake pedal, and after the pedal is stepped down, the vehicle is provided with a deceleration. The pedal adjusting structure 10 is used to adjust the reaction force acting on the pedal when the pedal is stepped down, to provide different pedal feelings for the driver, so that the driver can quickly adapt to the pedal.
[0035] On this basis, with reference to Figures 1-2 The embodiments of the present application provide a pedal assembly, which includes a pedal and a pedal adjusting structure 10. The pedal is a brake pedal, and the pedal is located in the cockpit. When the driver steps down the pedal, the pedal can provide a deceleration for the vehicle, so that the vehicle is decelerated or stopped. The pedal adjusting structure 10 is used to adjust the reaction force acting on the pedal. After the driver steps down the pedal, the reaction force can provide immediate operation feedback for the driver, so that the driver can perceive the force exerted on the pedal by himself, and different pedal feelings are provided for the driver.
[0036] The pedal adjusting structure 10 comprises a shell 1, an elastic element 2, a push rod 3 and an adjusting assembly 4, the elastic element 2 is located in the shell 1, and the shell 1 can provide a mounting space for the elastic element 2; one end of the push rod 3 extends into the shell 1 and is connected with the elastic element 2, and the other end of the push rod 3 extends out of the shell 1 and is connected with the pedal. After the pedal is stepped on, the pedal pushes the push rod 3 to move towards the elastic element 2 and compresses the elastic element 2, the elastic element 2 provides a reaction force to the push rod 3 when being compressed, the reaction force acting on the push rod 3 acts on the pedal and continues to act on the driver, and the pedal feeling is provided for the driver.
[0037] The adjusting assembly 4 is connected to one end of the elastic element 2 away from the push rod 3, that is, the two ends of the elastic element 2 are connected with the adjusting assembly 4 and the push rod 3 respectively, and the adjusting assembly 4 is used for driving the elastic element 2 to deform, so as to adjust the deformation amount of the elastic element 2. The elastic element 2 is located in the shell 1, and the space in the shell 1 is limited, so that the adjusting assembly 4 can drive the elastic element 2 to deform in the shell 1; the different deformation amounts of the elastic element 2 can provide different reaction forces for the pedal, and then different pedal feelings are provided for the driver. By changing the reaction force on the pedal through one elastic element 2, different pedal feelings can be provided for the driver.
[0038] When the pedal feeling needs to be adjusted, the adjusting assembly 4 is operated, the adjusting assembly 4 applies a force to the elastic element 2, so that the elastic element 2 deforms and changes the deformation amount. For example, the adjusting assembly 4 increases the force applied to the elastic element 2, the elastic element 2 is compressed, the reaction force of the elastic element 2 becomes larger, when the pedal is stepped on, the reaction force of the elastic element 2 acting on the push rod 3 increases, and finally the reaction force fed back to the pedal and the driver increases. For another example, the adjusting assembly 4 reduces the force applied to the elastic element 2, the elastic element 2 is elongated, the reaction force of the elastic element 2 becomes smaller, when the pedal is stepped on, the reaction force of the elastic element 2 acting on the push rod 3 decreases, and finally the reaction force fed back to the pedal and the driver is small. Thus, different pedal feelings are provided for the driver.
[0039] The pedal assembly provided by the embodiment of the application comprises the pedal adjusting structure 10, the pedal adjusting structure 10 comprises the adjusting assembly 4 and the elastic element 2, the adjusting assembly 4 drives the elastic element 2 to deform, so as to adjust the deformation amount of the elastic element 2, different reaction forces can be provided for the pedal, and then different pedal feelings are provided for the driver, so that the driver can adapt to driving in a short time.
[0040] Reference Figures 1-2In some embodiments of the present application, the adjusting assembly 4 comprises a hydraulic drive 41 and an elastic cavity 42. The hydraulic drive 41 is located outside the housing 1, and does not occupy the space inside the housing 1, so that the space inside the housing 1 is more compact. The elastic cavity 42 is located inside the housing 1, and one end of the elastic cavity 42 is connected to the end of the elastic member 2 away from the push rod 3, and the other end of the elastic cavity 42 abuts against the inner wall of the housing 1, so that the elastic cavity 42 can only move towards one side of the elastic member 2.
[0041] For example, the elastic cavity 42 can be a cavity composed of rubber material. The elastic cavity 42 is a rubber spring, which is a rubber shell with a cavity inside. The rubber spring has a plurality of wrinkles arranged around the rubber shell on the peripheral wall of the rubber shell, so that the rubber spring has a space for expansion or contraction, and the rubber material itself also has elasticity.
[0042] The hydraulic drive 41 can include a hydraulic cylinder and a hydraulic pump. The hydraulic cylinder stores oil, and the hydraulic pump is adapted to deliver or recover the oil in the hydraulic cylinder to the elastic cavity 42, so as to expand or contract the elastic cavity 42. When the hydraulic drive 41 delivers oil to the elastic cavity 42, the oil drives the elastic cavity 42 to expand. Due to the limited space inside the housing 1, the elastic cavity 42 expands to drive the elastic member 2 to compress, so that the reaction force of the elastic member 2 acting on the push rod 3 increases, and then the reaction force fed back to the pedal and the driver increases.
[0043] When the hydraulic drive 41 recovers the oil in the elastic cavity 42, the amount of oil in the elastic cavity 42 decreases. At this time, the elastic member 2 is elongated under the action of its own elastic force to drive the elastic cavity 42 to contract, so that the reaction force of the elastic member 2 acting on the push rod 3 decreases, and then the reaction force fed back to the pedal and the driver decreases.
[0044] By delivering or recovering the oil in the elastic cavity 42 through the hydraulic drive 41, the elastic cavity 42 is expanded or contracted, and then the elastic member 2 is compressed or elongated, so that the way of adjusting the deformation amount of the elastic member 2 is simple.
[0045] Referring to Figures 1-2 In some embodiments of the present application, the adjusting assembly 4 further comprises a first spring 43 telescopically located in the elastic cavity 42. The two ends of the first spring 43 are respectively connected to the inner wall of the elastic cavity 42. The first spring 43 can provide support force for the elongation of the elastic cavity 42. At the same time, after the pedal is stepped on, the pedal drives the push rod 3 to move towards the elastic member 2. When the push rod 3 drives the elastic member 2 to deform towards one side of the elastic cavity 42, the elastic cavity 42 is supported under the joint action of the first spring 43 and the oil, so as to avoid deformation of the elastic cavity 42 and displacement of the elastic member 2.
[0046] Referring to Figures 1-2 In some embodiments of the present application, the shell 1 has a transmission channel 11, which is in communication between the hydraulic driving member 41 and the elastic cavity 42, and the transmission channel 11 is provided with a switch valve 12 for connecting or disconnecting the hydraulic driving member 41 and the elastic cavity 42.
[0047] When the switch valve 12 is opened, the hydraulic driving member 41 and the elastic cavity 42 are in communication through the transmission channel 11, and the oil in the hydraulic driving member 41 can be transported into the elastic cavity 42, and the oil in the elastic cavity 42 can also be recovered into the hydraulic driving member 41 for expanding or shrinking the elastic cavity 42.
[0048] When the switch valve 12 is closed, the hydraulic driving member 41 and the elastic cavity 42 are disconnected, and the oil in the elastic cavity 42 can only be stored in the elastic cavity 42 for supporting the elastic cavity 42; after the pedal is stepped on, the pedal pushes the push rod 3 to move towards the elastic member 2, and when the push rod 3 pushes the elastic member 2 to compress on one side towards the elastic cavity 42, the oil supports the elastic cavity 42 to avoid the deformation of the elastic cavity 42, which causes the displacement of the elastic member 2, and further changes the reaction force acting on the push rod 3.
[0049] Referring to Figures 1-2 In some embodiments of the present application, the pedal adjusting structure 10 further comprises a partition plate 51 movably located between the elastic cavity 42 and the elastic member 2, and the two ends of the partition plate 51 can be connected with the elastic cavity 42 and the elastic member 2 respectively, and the partition plate 51 can move in the shell 1 when the elastic cavity 42 expands or shrinks.
[0050] When the elastic cavity 42 expands, the elastic cavity 42 drives the partition plate 51 to move towards the elastic member 2, and the partition plate 51 can bear a part of the driving force from the elastic cavity 42 when the elastic cavity 42 expands and moves, which can reduce the force transmitted to the elastic member 2, so that the elastic member 2 deforms slowly, avoiding the deformation of the elastic member 2 in an instant with too large deformation amount and losing the deformation ability.
[0051] When the elastic cavity 42 shrinks, the elastic member 2 drives the partition plate 51 to move towards the elastic cavity 42, and the partition plate 51 can bear a part of the deformation force from the elastic member 2 when the elastic cavity 42 expands and moves, which can make the elastic member 2 deform slowly, avoiding the deformation of the elastic member 2 in an instant with too large deformation amount and losing the deformation ability.
[0052] For example, the partition plate 51 can be a plastic part, which can make the partition plate 51 lighter and lower in cost.
[0053] Referring to Figures 1-3In some embodiments of the present application, the pedal adjusting structure 10 further comprises a force sensor 52, the push rod 3 comprises a first push rod 31 and a second push rod 32, and the force sensor 52 is connected between the first push rod 31 and the second push rod 32 and used to obtain the pedal force received by the push rod 3. The first push rod 31 can be connected to the pedal, and the second push rod 32 can be connected to the elastic member 2. Alternatively, the second push rod 32 can be connected to the pedal, and the first push rod 31 can be connected to the elastic member 2.
[0054] The force sensor 52 is arranged between the first push rod 31 and the second push rod 32, which can facilitate the force sensor 52 to obtain the pedal force received by the pedal. Moreover, the force sensor 52 is arranged between the first push rod 31 and the second push rod 32, and the first push rod 31 and the second push rod 32 can protect the force sensor 52 from being scratched by other components when the push rod 3 is in motion.
[0055] Referring to Figure 1 , Figure 3 , the elastic member 2 is in an initial state, which is the original state of the elastic member 2 when it is delivered from the factory. In the initial state, a certain force is applied to the pedal to drive the push rod 3 to move, and the push rod 3 drives the elastic member 2 to move when the push rod 3 is in motion. At this time, the force sensor 52 obtains the pedal force received by the push rod 3 and uploads it to the wheel end actuator. After receiving the pedal force, the braking system brakes to generate deceleration, and a pedal force-deceleration curve can be obtained, as shown in the initial state curve in FIG. 8. Figure 3
[0056] Referring to Figure 2 , Figure 3 , the deformation amount of the elastic member 2 is adjusted by the adjusting assembly 4, and the elastic member 2 is in an adjusted state. In the adjusted state, a certain force is applied to the pedal to drive the push rod 3 to move, and the push rod 3 drives the elastic member 2 to move when the push rod 3 is in motion. At this time, the force sensor 52 obtains the pedal force received by the push rod 3 and uploads it to the wheel end actuator. After receiving the pedal force, the braking system brakes to generate deceleration, and a pedal force-deceleration curve can be obtained, as shown in the adjusted state curve in FIG. 9. Figure 3
[0057] If the same deceleration is required, the pedal force required in the initial state is relatively small, and the pedal force required in the adjusted state is relatively large.
[0058] Different curves represent different pedal feelings. The deformation amount of the elastic member 2 is different, the reaction force acting on the pedal and the driver is different, and the pedal feeling obtained by the driver is different. By adjusting the deformation amount of the elastic member 2, different pedal feelings can be provided for the driver, which can adapt to the pedal force and pedal habits of different drivers.
[0059] Referring to Figures 1-2 ,Figure 4 In some embodiments of the present application, the pedal adjusting structure 10 further comprises a displacement sensor 53 fixed in the housing 1, the displacement sensor 53 being used to obtain the displacement of the push rod 3, the displacement sensor 53 being located on one side of the push rod 3, and the displacement of the push rod 3 being obtained when the push rod 3 moves towards the elastic member 2.
[0060] With reference to Figure 1 , Figure 4 , the elastic member 2 is in an initial state, which is the original state of the elastic member 2 when it leaves the factory. In the initial state, a certain force is applied to step on the pedal, the pedal drives the push rod 3 to move, the push rod 3 drives the elastic member 2 to move when the push rod 3 moves, at this time, the displacement sensor 53 obtains the displacement of the push rod 3 and uploads it to the wheel end actuator, the brake system receives the displacement to brake to generate deceleration, and the displacement-deceleration curve can be obtained, with reference to the curve of the initial state in FIG. 8. Figure 4
[0061] With reference to Figure 2 , Figure 4 , the deformation amount of the elastic member 2 is adjusted by the adjusting assembly 4, and the elastic member 2 is in an adjusted state. In the adjusted state, a certain force is applied to step on the pedal, the pedal drives the push rod 3 to move, the push rod 3 drives the elastic member 2 to move when the push rod 3 moves, at this time, the displacement sensor 53 obtains the displacement of the push rod 3 and uploads it to the wheel end actuator, the brake system receives the displacement to brake to generate deceleration, and the displacement-deceleration curve can be obtained, with reference to the curve of the adjusted state in FIG. 8. Figure 4
[0062] If the same deceleration is to be obtained, the displacement in the initial state is relatively long, and the displacement in the adjusted state is relatively short.
[0063] Different curves represent different pedal feelings, the deformation amount of the elastic member 2 is different, the reaction force acting on the pedal and the driver is different, and the pedal feeling obtained by the driver is different. By adjusting the deformation amount of the elastic member 2, different pedal feelings are provided for the driver, which can adapt to the stepping force and stepping habit of different drivers.
[0064] With reference to Figures 1-2 In some embodiments of the present application, the elastic member 2 comprises a second spring, so that the structure of the elastic member 2 is simple and convenient to install.
[0065] With reference to Figures 1-2 In some embodiments of the present application, the shell 1 comprises a first shell 13 and a second shell 14, which are detachably connected, for example, the first shell 13 and the second shell 14 can be bolted. The first shell 13 has a first accommodating cavity 131, and the second shell 14 has a second accommodating cavity 141, which is in communication with the first accommodating cavity 131. The second accommodating cavity 141 has an opening arranged away from the first accommodating cavity 131. The elastic cavity 42 and the elastic member 2 are located in the first accommodating cavity 131, and the push rod 3 is located in the second accommodating cavity 141 and extends out of the second accommodating cavity 141 along the opening.
[0066] The shell 1 is arranged to detachably connect the first shell 13 and the second shell 14, which can facilitate the installation of the elastic cavity 42 and the elastic member 2.
