Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a pedal feel simulator and a vehicle. Background Technology

[0002] With the development of intelligent and autonomous vehicles, brake-by-wire systems have become a future trend. To complement brake-by-wire systems, electronic brake pedals have been widely adopted. Compared to traditional brake pedals, electronic brake pedals no longer have a traditional lever structure. When the driver presses the electronic brake pedal, it provides no resistance, and the driver's foot does not feel any impact, thus reducing the driver's sense of security during driving.

[0003] Therefore, a pedal feel simulator needs to be added to the electronic brake pedal to simulate pedal feel. Existing pedal feel simulators typically consist of springs and rubber, which cannot accurately simulate pedal feel and have limited adjustability, thus failing to meet the different pedal feel requirements of various drivers and affecting the driver's sense of security during driving. Utility Model Content

[0004] In view of this, the present application provides a pedal feel simulator and a vehicle to solve the technical problem that the pedal feel simulator has limited adjustability and cannot accurately simulate pedal feel, so as to adapt to the different needs of different drivers for pedal feel and improve the driver's sense of security during driving.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a pedal feel simulator.

[0007] The pedal feel simulator provided in this application includes:

[0008] A fixing assembly, the fixing assembly including a first housing and a first magnetic field component, the first magnetic field component including a first magnetic field part, at least a portion of the first magnetic field part being disposed within the first housing;

[0009] The movable component includes a second housing and a second magnetic field component, the second housing being movably disposed within the first housing so that the second housing can extend and retract relative to the first housing; the second magnetic field component includes a second magnetic field portion, at least a portion of the second magnetic field portion being disposed within the second housing;

[0010] The fixed component is used to connect to the pedal seat at one end away from the movable component, and the movable component is used to movably connect to the brake pedal at one end away from the fixed component; at least one of the first magnetic field part and the second magnetic field part includes an electromagnet, and the first magnetic field part and the second magnetic field part have the same magnetic poles at their adjacent ends.

[0011] The pedal feel simulator of this application embodiment includes a fixed component and a movable component. The fixed component generates a magnetic field by providing a first magnetic field section within a first housing. The movable component also generates a magnetic field by providing a second magnetic field section within a second housing.

[0012] The second housing is movably disposed within the first housing. The fixed component is connected to the pedal seat at the end opposite to the movable component, and the movable component is movably connected to the brake pedal at the end opposite to the fixed component. Furthermore, the first and second magnetic field units have the same magnetic poles at their adjacent ends. Through the principle of like poles repelling each other, a repulsive force exists between the fixed and movable components. When the driver depresses the brake pedal, the brake pedal drives the movable component closer to the fixed component, while the fixed component remains stationary, providing support for the pedal simulator. As the movable component approaches, the overlap area between the magnetic fields of the movable and fixed components increases, thus increasing the repulsive force. The repulsive force from the first magnetic field unit acts on the movable component, which transmits the repulsive force to the brake pedal. The brake pedal then feeds back the repulsive force to the driver, allowing the driver to feel the pedal, thereby improving the driver's sense of security during driving.

[0013] By including an electromagnet in at least one of the first and second magnetic field sections, the magnetic field strength can be precisely controlled by adjusting the current, thereby changing the magnitude of the repulsive force to adapt to the different needs of different drivers for pedal feel, thus improving the adaptability and adjustability of the pedal feel simulator.

[0014] Therefore, the pedal feel simulator of this application embodiment includes a fixed component and a movable component. The fixed component has a first magnetic field part, and the movable component has a second magnetic field part. The first and second magnetic field parts have the same magnetic poles at their adjacent ends. By utilizing the principle of like poles repulsion, the driver's pedaling action is converted into a repulsive force acting on the brake pedal, allowing the driver to feel the pedal feel and thus improving the driver's sense of security during driving. Furthermore, since at least one of the first and second magnetic field parts includes an electromagnet, changing the current magnitude can change the magnitude of the repulsive force, thereby adapting to different drivers' varying needs for pedal feel and improving the adaptability and adjustability of the pedal feel simulator.

[0015] In one possible implementation of this application, the pedal feel simulator further includes an elastic support member, a portion of which is disposed within the first housing and fixed relative to the first housing, and the remaining portion of which is disposed within the second housing and fixed relative to the second housing.

[0016] When the second housing moves within the first housing, the elastic support can extend and retract relative to the first housing.

[0017] In one possible implementation of this application, the elastic support is disposed around the circumferential outer side of the first magnetic field portion and the second magnetic field portion, and there is a gap between the elastic support and the first magnetic field portion and the second magnetic field portion.

[0018] In one possible implementation of this application, the first magnetic field component further includes a first mounting portion, the first magnetic field component is mounted on the first mounting portion, at least a portion of the first mounting portion is disposed within the first housing and is fixed relative to the first housing;

[0019] One end of the elastic support abuts against the inner wall of the first mounting portion or the first housing.

[0020] In one possible implementation of this application, the first mounting part is provided with a first slot, and one end of the elastic support member is disposed in the first slot and abuts against the bottom wall of the first slot.

[0021] In one possible implementation of this application, the second magnetic field component further includes a second mounting portion, the second magnetic field component is mounted on the second mounting portion, at least a portion of the second mounting portion is disposed within the second housing and is fixed relative to the second housing;

[0022] The other end of the elastic support abuts against the inner wall of the second mounting portion or the second housing.

[0023] In one possible implementation of this application, when the second mounting part is disposed inside the second housing, the second mounting part and the second housing together form a second slot, and the other end of the elastic support member is disposed inside the second slot and abuts against the bottom wall of the second slot.

[0024] In one possible implementation of this application, the electromagnet includes an iron core and an energized coil, the iron core being disposed within the first housing and / or the second housing, and the energized coil being wound around the iron core;

[0025] When both the first magnetic field component and the second magnetic field component are electromagnets, the iron core in the first magnetic field component and the iron core in the second magnetic field component have the same magnetic poles at their adjacent ends.

[0026] In one possible implementation of this application, the end of the first housing and / or the first magnetic element facing away from the active component is used to connect to the pedal seat;

[0027] And / or, the end of the second housing and / or the second magnetic element facing away from the fixed assembly is used for connection with the brake pedal.

[0028] Secondly, embodiments of this application provide a vehicle, including:

[0029] pedal seat;

[0030] A brake pedal, the brake pedal including a pedal part and a connecting arm, one end of the connecting arm being movably connected to the pedal part;

[0031] In any embodiment of the first aspect described above, the fixed component of the pedal feel simulator is connected to the pedal seat, and the movable component of the pedal feel simulator is connected to the other end of the connecting arm.

[0032] This application provides a vehicle that includes the pedal feel simulator provided in any of the embodiments of the first aspect. Therefore, the pedal feel simulator used in this vehicle also has the same technical effect as the pedal feel simulator provided in the first aspect, that is, it enables the driver to feel the pedal feel and can adapt to the different needs of different drivers for pedal feel, thereby improving the adaptability and adjustability of the pedal feel simulator and the driver's sense of security during driving.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0047] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0048] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0049] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0050] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0051] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0052] This application provides a vehicle embodiment. It should be noted that this application embodiment does not limit the vehicle type. For example, the vehicle in this application embodiment can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0053] In this application embodiment, the type of power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0054] The vehicle provided in this application includes a pedal mount and a brake pedal. The pedal mount is typically located on the chassis or front bulkhead of the vehicle and serves to provide a supporting base for the installation of the brake pedal, bearing the force exerted by the driver when pressing the brake pedal. The pedal mount is typically a frame structure made of metal.

[0055] The brake pedal includes a pedal body and a connecting arm. One end of the connecting arm is movably connected to the pedal seat, and the other end is connected to the pedal body. The driver can control the vehicle's braking by using the brake pedal.

[0056] With the development of intelligent and unmanned vehicles, brake-by-wire systems have become a future trend. A brake-by-wire system is a braking system that replaces traditional mechanical or hydraulic connections with an electronic control system.

[0057] In traditional technology, vehicles typically brake via mechanical or hydraulic mechanisms. Specifically, when the driver presses the brake pedal, the force is directly transmitted to the brake wheel cylinders via a mechanical or hydraulic mechanism, causing the wheels to brake. A brake-by-wire system, however, converts the driver's action of pressing the brake pedal into an electrical signal. This signal is processed by the electronic control unit (ECU) and then instructs the actuator (such as a motor or hydraulic pump) to generate braking force, thus braking the wheels.

[0058] Electronic brake pedals have been widely used to complement brake-by-wire systems. Compared to traditional brake pedals, electronic brake pedals no longer use a traditional lever structure.

[0059] The electronic brake pedal integrates sensor components (such as angle sensors, displacement sensors, or force sensors). When the driver presses the electronic brake pedal, it collects the driver's pressing action signal, converts it into an electrical signal, and transmits it to the electronic control unit (ECU). The ECU then controls the actuator to perform the vehicle's braking operation.

[0060] However, electronic brake pedals are usually not physically connected to the actuators. When the driver presses the brake pedal, the electronic brake pedal cannot provide the pedal feel provided by the traditional brake pedal, which affects the driver's foot feel and reduces the driver's sense of security during driving.

[0061] Therefore, a pedal feel simulator is needed when using an electronic brake pedal to simulate pedal feel. Existing pedal feel simulators typically consist of springs and rubber, which cannot accurately simulate pedal feel. Their adjustability is limited, making them unsuitable for different drivers' varying pedal feel preferences and impacting the driver's sense of security while driving.

[0062] Therefore, how to make the pedal feel simulator accurately simulate the pedal feel and improve the adjustability of the pedal feel to adapt to the different needs of different drivers for pedal feel and improve the driver's sense of security during driving is a technical problem that urgently needs to be solved.

[0063] In view of this, the present application provides a pedal feel simulator, including a fixed component and a movable component. The fixed component has a first magnetic field part, and the movable component has a second magnetic field part. The first and second magnetic field parts have the same magnetic poles at their adjacent ends. Utilizing the principle of like poles repulsion, the driver's pedaling action is converted into a repulsive force acting on the brake pedal, allowing the driver to feel the pedal and thus improving the driver's sense of security during driving. Furthermore, since at least one of the first and second magnetic field parts includes an electromagnet, changing the current magnitude can change the magnitude of the repulsive force, thereby adapting to different drivers' varying needs for pedal feel and improving the adaptability and adjustability of the pedal feel simulator.

[0064] The following description, in conjunction with the accompanying drawings and embodiments, further illustrates a pedal feel simulator provided in this application.

[0065] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This application provides a pedal feel simulator, which includes a fixed component 100 and a movable component 200.

[0066] The fixing assembly 100 includes a first housing 110 and a first magnetic field component 120. The first magnetic field component 120 includes a first magnetic field portion 121, at least a portion of which is disposed within the first housing 110. By having the first magnetic field component 120 disposed within the first housing 110, the fixing assembly 100 generates a magnetic field.

[0067] The movable component 200 includes a second housing 210 and a second magnetic field component 220. The second magnetic field component 220 includes a second magnetic field portion 221, at least a portion of which is disposed within the second housing 210. The second magnetic field component 220 being disposed within the second housing 210 causes the movable component 200 to generate a magnetic field.

[0068] The second housing 210 is movably disposed within the first housing 110, so that the second housing 210 can extend and retract relative to the first housing 110. By extending and retracting the second housing 210 relative to the first housing 110, the distance and overlap area between the magnetic field of the fixed component 100 and the magnetic field of the movable component 200 can be changed.

[0069] The fixed assembly 100 is connected to the pedal base 300 at its end opposite to the movable assembly 200. The fixed assembly 100 is mounted on the pedal base 300 at its end opposite to the movable assembly 200, thus keeping the fixed assembly 100 stationary throughout operation. The fixed assembly 100 provides support for the entire pedal feel simulator via the pedal base 300.

[0070] It should be noted that the fixed component 100 is used to connect to the pedal seat 300 at the end opposite to the movable component 200. The connection between the fixed component 100 and the pedal seat 300 is a relatively fixed connection, rather than a connection in which the two can move relative to each other.

[0071] The movable component 200 is movably connected to the brake pedal 400 at its end opposite to the fixed component 100. Exemplarily, the end of the movable component 200 opposite to the fixed component 100 is connected to the brake pedal 400 via a pin. The brake pedal 400 can swing about the pin. When the brake pedal 400 swings, the movable component 200 moves linearly relative to the first housing 110. This movable connection between the movable component 200 and the brake pedal 400 prevents the movable component 200 from getting stuck within the first housing 110, which could cause abnormal noise, accelerate wear, and reduce the service life of the pedal feel simulator.

[0072] The first magnetic field section 121 and the second magnetic field section 221 have the same magnetic poles at their adjacent ends. According to the principle that like poles repel each other, a repulsive force is generated between the first magnetic field section 121 and the second magnetic field section 221. Since the second housing 210 can extend and retract relative to the first housing 110, when the second housing 210 approaches the first housing 110, the distance between the two magnetic fields decreases, the overlap area of ​​the two magnetic fields increases, the interaction of the magnetic flux is enhanced, and the repulsive force between the first magnetic field section 121 and the second magnetic field section 221 is strengthened.

[0073] When the driver presses the brake pedal 400, a force is applied to it. The brake pedal 400 transmits this force to the movable component 200, which drives the movable component 200 to move along the first housing 110 toward the fixed component 100. As the movable component 200 approaches the fixed component 100, the distance between the magnetic fields of the fixed component 100 and the movable component 200 decreases, the overlap area increases, the interaction of magnetic fluxes intensifies, and the repulsive force between the first magnetic field section 121 and the second magnetic field section 221 intensifies. The direction of the repulsive force is opposite to the direction of movement of the movable component 200. The repulsive force acts on the movable component 200, which then transmits the repulsive force back to the brake pedal 400. The brake pedal 400 then feeds the repulsive force back to the driver, allowing the driver to feel the pedal and improving the driver's sense of driving safety.

[0074] The interaction between the magnetic field of the fixed component 100 and the magnetic field of the movable component 200 makes the displacement of the brake pedal 400 proportional to the repulsive force, accurately simulating the pedal feel of the traditional brake pedal 400 and enhancing the pedal feel feedback that the driver can perceive.

[0075] At least one of the first magnetic field unit 121 and the second magnetic field unit 221 includes an electromagnet. The magnetic field strength can be changed by altering the magnitude of the current input to the electromagnet. When the current increases, the magnetic field strength increases, and the repulsive force increases. When the current decreases, the magnetic field strength decreases, and the repulsive force decreases. The driver can adjust the pedal feel by controlling the current magnitude, allowing the pedal feel simulator to adapt to different drivers' varying pedal feel requirements, thus improving the adaptability and adjustability of the pedal feel simulator.

[0076] For example, the first magnetic field section 121 may be an electromagnet, and the second magnetic field section 221 may be a magnet. Alternatively, the second magnetic field section 221 may be an electromagnet, and the first magnetic field section 121 may be a magnet. Or, both the first magnetic field section 121 and the second magnetic field section 221 may be electromagnets.

[0077] The pedal feel simulator of this application embodiment includes a fixed component 100 and a movable component 200. The fixed component 100 forms a magnetic field by providing a first magnetic field section 121 within a first housing 110. The movable component 200 also forms a magnetic field by providing a second magnetic field section 221 within a second housing 210.

[0078] The second housing 210 is movably disposed within the first housing 110. The fixed assembly 100 is connected to the pedal seat 300 at the end opposite to the movable assembly 200, and the movable assembly 200 is movably connected to the brake pedal 400 at the end opposite to the fixed assembly 100. Furthermore, the first magnetic field part 121 and the second magnetic field part 221 have the same magnetic poles at their adjacent ends, and through the principle of like poles repelling each other, a repulsive force exists between the fixed assembly 100 and the movable assembly 200.

[0079] When the driver presses the brake pedal 400, the brake pedal 400 drives the movable component 200 closer to the fixed component 100, while the fixed component 100 remains stationary, providing support for the pedal simulator. As the movable component 200 approaches, the overlap area between the magnetic fields of the movable component 200 and the fixed component 100 increases, resulting in a greater repulsive force. The repulsive force from the first magnetic field unit 121 acts on the movable component 200, which transmits the repulsive force to the brake pedal 400. The brake pedal 400 then feeds the repulsive force back to the driver, allowing the driver to feel the pedal and thus improving the driver's sense of security during driving.

[0080] By including an electromagnet in at least one of the first magnetic field section 121 and the second magnetic field section 221, the magnetic field strength can be precisely controlled by adjusting the current, thereby changing the magnitude of the repulsive force to adapt to the different needs of different drivers for pedal feel, thus improving the adaptability and adjustability of the pedal feel simulator.

[0081] Therefore, the pedal feel simulator of this application embodiment includes a fixed component 100 and a movable component 200. The fixed component 100 has a first magnetic field section 121, and the movable component 200 has a second magnetic field section 221. The first magnetic field section 121 and the second magnetic field section 221 have the same magnetic poles at their adjacent ends. By utilizing the principle of repulsion between like magnetic poles, the driver's pedaling action is converted into a repulsive force acting on the brake pedal 400, allowing the driver to feel the pedal feel and thus improving the driver's sense of security during driving. Furthermore, since at least one of the first magnetic field section 121 and the second magnetic field section 221 includes an electromagnet, changing the current magnitude can change the magnitude of the repulsive force, thereby adapting to the different pedal feel requirements of different drivers and improving the adaptability and adjustability of the pedal feel simulator.

[0082] See Figure 2 , Figure 4 and Figure 5 In some embodiments, the pedal feel simulator further includes an elastic support 500. A portion of the elastic support 500 is disposed within and fixed relative to the first housing 110, and the remaining portion is disposed within and fixed relative to the second housing 210. When the second housing 210 moves within the first housing 110, the elastic support 500 can extend and retract relative to the first housing 110.

[0083] For example, the elastic support 500 can be a spring, with a portion of the spring disposed within the first housing 110 and the remainder disposed within the second housing 210. When the driver does not depress the brake pedal 400, the spring is in its natural or pre-compressed state, and the movable component 200 is located at its furthest point from the fixed component 100. At this time, the distance between the magnetic field of the fixed component 100 and the magnetic field of the movable component 200 is the greatest, and the repulsive force is minimal.

[0084] See Figure 1 When the driver depresses the brake pedal 400, the brake pedal 400 pushes the movable component 200 along the first housing 110 toward the fixed component 100. As the movable component 200 approaches, the distance between the magnetic fields of the movable component 200 and the fixed component 100 decreases, the overlap area increases, and the repulsive force increases. Furthermore, the second housing 210 compresses the spring, causing the spring to deform. At this time, the pedal feel experienced by the driver is a combined feedback of repulsive force and elastic force.

[0085] See Figure 3 When the driver releases the brake pedal 400, the spring rebounds and provides elastic force to the second housing 210, pushing the second housing 210 and the movable component 200 back to their initial positions. The distance between the magnetic field of the movable component 200 and the magnetic field of the fixed component 100 increases, and the overlap area decreases, thus reducing the repulsive force.

[0086] The elastic support 500 can further optimize the pedal feel felt by the driver. When the first magnetic field part 121 and the second magnetic field part 221 are damaged, the elastic force of the elastic support 500 can still provide the driver with pedal feel and can make the brake pedal 400 automatically reset, preparing for the next use of the brake pedal 400 and improving the response speed of the braking system.

[0087] See Figure 2 and Figure 4 In some embodiments, the elastic support 500 is disposed around the circumferential outer side of the first magnetic field section 121 and the second magnetic field section 221. By distributing the elastic support 500 around the circumferential outer side of the first magnetic field section 121 and the second magnetic field section 221, internal installation space of the pedal-sensing simulator is saved, and the first magnetic field section 121 and the second magnetic field section 221 can be protected from direct damage in the event of accidental impact or loosening of internal parts.

[0088] A gap exists between the elastic support 500 and the first magnetic field section 121 and the second magnetic field section 221. This gap prevents wear between the elastic support 500 and the first and second magnetic field sections 121. Furthermore, the elastic support 500 is typically made of metal, and the gap prevents mutual interference between the elastic support 500 and the first and second magnetic field sections 121.

[0089] See Figure 2 and Figure 4 In some embodiments, the first magnetic field component 120 further includes a first mounting portion 122, the first magnetic field component 121 is mounted on the first mounting portion 122, and at least a portion of the first mounting portion 122 is disposed within the first housing 110 and is fixed relative to the first housing 110.

[0090] For example, the first magnetic field unit 121 can be installed on the first mounting part 122 first, and then the first mounting part 122 and the first magnetic field unit 121 can be installed in the first housing 110, which can improve the accuracy of the installation of the first magnetic field unit 121, thereby ensuring the efficiency and stability of the magnetic field effect.

[0091] One end of the elastic support 500 abuts against the inner wall of the first mounting portion 122 or the first housing 110. Since the first mounting portion 122 and the first housing 110 are relatively fixed, and the first housing 110 is mounted on the pedal seat 300, the end of the elastic support 500 abutting against the inner wall of the first mounting portion 122 or the first housing 110 remains stationary. This allows the elastic component to be compressed and generate elastic force when the movable component 200 moves.

[0092] See Figure 2 and Figure 4 In some embodiments, the first mounting portion 122 has a first slot 1221 inside, and one end of the elastic support member 500 is disposed in the first slot 1221 and abuts against the bottom wall of the first slot 1221. The first slot 1221 restricts the installation position of the elastic support member 500, provides positioning and guidance for the installation of the elastic support member 500, and improves the installation accuracy of the elastic support member 500.

[0093] Furthermore, when the driver presses or releases the brake pedal 400, the elastic support 500 deforms along the extension direction of the slot, so that the deformation direction of the elastic support 500 is consistent with the axis of the first magnetic field component 120, avoiding unnecessary jamming and wear when the movable component 200 extends or retracts, and improving the stability of the device.

[0094] See Figure 2 and Figure 4 In some embodiments, the second magnetic field component 220 further includes a second mounting portion 222, on which the second magnetic field component 221 is mounted. At least a portion of the second mounting portion 222 is disposed within the second housing 210 and is fixed relative to the second housing 210. The other end of the elastic support component 500 abuts against the inner wall of the second mounting portion 222 or the second housing 210.

[0095] For example, the second magnetic field unit 221 can be installed on the second mounting part 222 first, and then the second mounting part 222 and the second magnetic field unit 221 can be installed in the second housing 210. This can improve the accuracy of the installation of the second magnetic field unit 221, thereby ensuring the efficiency and stability of the magnetic field effect.

[0096] When the movable component 200 extends or retracts, it drives the second housing 210 to extend or retract. The second mounting part 222 is located inside the second housing 210. Therefore, when the other end of the elastic support 500 abuts against the second mounting part 222 or the inner wall of the second housing 210, the second housing 210 will cause the elastic support 500 to deform, thereby enabling the elastic support 500 to provide elastic force, drive the movable component 200 back to the initial position, and together with the repulsive force, provide the driver with a pedal feel.

[0097] See Figure 2 and Figure 4In some embodiments, when the second mounting portion 222 is disposed within the second housing 210, the second mounting portion 222 and the second housing 210 together form a second slot 2221. The other end of the elastic support member 500 is disposed within the second slot 2221 and abuts against the bottom wall of the second slot 2221. The second slot 2221 further restricts the installation position of the elastic support member 500, providing positioning and guidance for the installation of the elastic support member 500, thereby improving the installation accuracy of the elastic support member 500.

[0098] Furthermore, when the driver presses or releases the brake pedal 400, the elastic support 500 deforms along the extension direction of the slot, so that the deformation direction of the elastic support 500 is consistent with the axis of the second magnetic field component 220, avoiding unnecessary jamming and wear when the movable component 200 extends or retracts, and improving the stability of the device.

[0099] See Figure 2 and Figure 4 In some embodiments, the electromagnet includes an iron core 600 and an energized coil 700. The iron core 600 is disposed within the first housing 110 and / or the second housing 210, and the energized coil 700 is wound around the iron core 600. When both the first magnetic field element 120 and the second magnetic field element 220 are electromagnets, the iron core 600 in the first magnetic field element 120 and the iron core 600 in the second magnetic field element 220 have the same magnetic poles at their adjacent ends.

[0100] For example, both the first magnetic field element 120 and the second magnetic field element 220 are electromagnets. The iron core 600 of the first magnetic field element 120 is disposed within the first housing 110. The iron core 600 of the second magnetic field element 220 is disposed within the second housing 210. The iron core 600 of the first magnetic field element 120 and the iron core 600 of the second magnetic field element 220 have the same magnetic poles at their adjacent ends.

[0101] When the driver presses the brake pedal 400, the brake pedal 400 can collect the pedal displacement information through a displacement sensor. This displacement information can be converted into an electrical signal, which is transmitted to the vehicle's control unit. The vehicle's control unit calculates the repulsive force required to simulate the pedal feel and outputs current to the energized coils 700 of the first magnetic field element 120 and the second magnetic field element 220, respectively. The current flowing through the energized coils 700 of the first magnetic field element 120 and the second magnetic field element 220 generates magnetic fields on the iron cores 600 of the first magnetic field element 120 and the second magnetic field element 220, respectively, according to the principle of electromagnetic induction. By controlling the direction of the current, the iron cores 600 in the first magnetic field element 120 and the second magnetic field element 220 can have the same magnetic poles at their close ends, thereby generating a repulsive force.

[0102] Since at least one of the first magnetic field component 120 and the second magnetic field component 220 is an electromagnet, the magnetic field strength can be changed by changing the magnitude of the current, thereby changing the magnitude of the repulsive force. This allows the pedal feel simulator to adapt to the different pedal feel requirements of different drivers, improving the adaptability and adjustability of the pedal feel simulator.

[0103] See Figure 1 and Figure 3 In some embodiments, the end of the first housing 110 and / or the first magnetic field element 120 facing away from the active assembly 200 is used to connect to the pedal seat 300.

[0104] And / or, one end of the second housing 210 and / or the second magnetic field element 220 facing away from the fixing assembly 100 is used to connect to the brake pedal 400.

[0105] For example, one end of the first housing 110 away from the movable component 200 may be connected to the pedal seat 300. Alternatively, one end of the first magnetic component 120 away from the movable component 200 may be connected to the pedal seat 300. For instance, the first mounting portion 122 may partially extend outside the first housing 110, and the portion of the first mounting portion 122 extending outside the first housing 110 may be connected to the pedal seat 300. Alternatively, both one end of the first housing 110 away from the movable component 200 and one end of the first magnetic component 120 away from the movable component 200 may be connected to the pedal seat 300.

[0106] See Figure 1 and Figure 2 One end of the second housing 210 facing away from the fixing assembly 100 can be connected to the brake pedal 400. Alternatively, one end of the second magnetic field member 220 facing away from the fixing assembly 100 can be connected to the brake pedal 400. For example, the second mounting portion 222 can partially extend outside the second housing 210, and the portion of the second mounting portion 222 extending outside the second housing 210 is connected to the brake pedal 400. Alternatively, both one end of the second housing 210 facing away from the fixing assembly 100 and one end of the second magnetic field member 220 facing away from the fixing assembly 100 can be connected to the brake pedal 400.

[0107] Depending on the different installation environment, the most suitable installation method can be selected, which increases the versatility of the device.

[0108] Secondly, this application also provides a vehicle. The vehicle includes a pedal seat 300, a brake pedal 400, and a pedal feel simulator provided in any embodiment of this application.

[0109] See Figure 1 and Figure 2The brake pedal 400 includes a pedal portion 410 and a connecting arm 420. One end of the connecting arm 420 is movably connected to the pedal portion 410, and the other end of the connecting arm 420 is connected to the pedal seat 300. The fixed component 100 in the pedal feel simulator is connected to the pedal seat 300, and the movable component 200 in the pedal feel simulator is connected to the other end of the connecting arm 420, thus enabling the pedal feel simulator to be movably connected between the pedal seat 300 and the brake pedal 400.

[0110] For example, one end of the pedal portion 410 and the connecting arm 420 are connected by a pin. The other end of the connecting arm 420 is connected to the second housing 210 or the second magnetic field member 220 in the movable assembly 200. When the driver presses the pedal portion 410, the pedal portion 410 swings about the pin. The connecting arm 420 provides a pivot point for the swing of the pedal portion 410, and the swing is converted into linear motion of the movable assembly 200 relative to the fixed assembly 100.

[0111] The pedal seat 300, brake pedal 400, and pedal feel simulator provided in any embodiment of this application have all been described above and will not be repeated here.

[0112] Since the vehicle provided in this application includes the pedal feel simulator provided in any embodiment of this application, the vehicle provided in this application has the same effect, that is, it enables the driver to feel the pedal feel and can adapt to the different needs of different drivers for pedal feel, thereby improving the adaptability and adjustability of the pedal feel simulator and the driver's sense of security during driving.
