The first elastic part 3 is arranged in the shell, and two ends of the first elastic part 3 are respectively matched with the inner wall of the shell 1 and the second end 23b of the motor push rod 23; the second elastic element 4 is arranged in the shell 1, the second elastic element 4 and the first elastic element 3 are positioned at two axial sides of the motor primary 21, and two ends of the second elastic element 4 are respectively matched on the motor push rod 23 and the motor primary 21.
For example, as shown in fig. 1 to 6, the housing 1 may be formed substantially in a cylindrical structure and an accommodating space may be defined in the housing 1, the motor primary 21 and the motor secondary 22 may be both located in the accommodating space, the motor primary 21 is fixed on the housing 1 to support the housing 1, further ensuring the strength and stability of the housing 1, and the motor push rod 23 may be inserted through the housing 1 such that a portion of the motor push rod 23 is located in the accommodating space and another portion of the motor push rod 23 is located outside the accommodating space.
The motor primary 21 and the motor secondary 22 may both form an annular structure, the motor push rod 23, the motor secondary 22 and the motor primary 21 may be sequentially arranged from inside to outside, that is, the motor secondary 22 is sleeved outside the motor push rod 23, and the motor primary 21 is sleeved outside the motor secondary 22, wherein the motor secondary 22 may be fixed on the motor push rod 23, and the motor primary 21 and the motor secondary 22 are arranged at intervals inside and outside, and the motor primary 21 and the motor secondary 22 interact with each other to enable the motor secondary 22 to move relative to the motor primary 21 along the axial direction of the linear motor 2, so that the motor secondary 22 may drive the motor push rod 23 to move synchronously. The linear motor 2 has the advantages of compact structure, low power loss, high reaction speed, accurate positioning, low noise, long service life and the like.
The second elastic element 4 and the first elastic element 3 are respectively positioned at two axial sides of the motor primary 21, two ends of the first elastic element 3 are respectively matched at the inner wall of the shell 1 and the second end 23b of the motor push rod 23, two ends of the second elastic element 4 are respectively abutted against the motor push rod 23 and the motor primary 21, so that when the vehicle needs to be braked and the motor push rod 23 moves along the axial direction of the linear motor 2, the axial distance between the second end 23b of the motor push rod 23 and the inner wall of the housing 1 changes, and the axial distance between the motor push rod 23 and the motor primary 21 also changes, the first elastic member 3 and/or the second elastic member 4 can apply an elastic force to the motor push rod 23, and the first end 23a of the motor push rod 23 is connected with the pedal 101, so that the sum of the first spring force 3 and/or the second spring member 4 can provide the basic pedal reaction force.
When the pedal feel simulator 100 is applied to a vehicle, when the vehicle needs to be braked, a driver depresses the pedal 101 to transmit a pedaling force of the driver to the linear motor 2, the first elastic member 3 and/or the second elastic member 4 through the motor push rod 23, and the first elastic member 3 and/or the second elastic member 4 can apply an elastic force to the motor push rod 23 to provide a basic pedal reaction force, so that a 'braking feel' of the pedal 101 when the brake system works is ensured; the detection device on the vehicle, for example, the sensor, may detect parameters such as the magnitude of the pedaling force, the moving displacement of the motor push rod 23 or the motor secondary 22, the moving speed of the motor push rod 23 or the motor secondary 22, and transmit the detection result to an Electronic Control Unit (ECU) of the vehicle to analyze the detection result, so as to calculate an optimal target pedal reaction force and a compensation force that the linear motor 2 needs to provide, where the compensation force that the linear motor 2 needs to provide may be a difference between the optimal target pedal reaction force and the base pedal reaction force, and at this time, the Electronic Control Unit transmits the optimization result to the linear motor 2, and the linear motor 2 receives signals to enable the motor primary 21 and the motor secondary 22 to interact with each other, so that the motor secondary 22 can apply a corresponding compensation force to the motor push rod 23, and the sum of the base pedal reaction force and the compensation force to form the optimal target pedal reaction force, the optimal target pedal reaction force acts on the motor push rod 23 to be matched with the running state of the real vehicle, so that the pedal feeling effect of a driver when stepping on the pedal 101 can be improved, and the operation comfort of the driver can be improved; meanwhile, the electronic control unit can analyze and obtain a final braking scheme according to the optimal target pedal reaction force and by combining the running state, the real-time road condition and the like of the real vehicle, and transmits corresponding signals to the actuating mechanism to realize the braking of the vehicle.
Here, it should be noted that the "brake feeling" is a comprehensive feeling, and may include a pedal brake feeling, which is the most important component, a vehicle brake deceleration felt by the driver, an audible brake noise, a visual vehicle deceleration, and the like.
It can be understood that two ends of the first elastic member 3 are respectively engaged with the inner wall of the housing 1 and the second end 23b of the motor push rod 23, two ends of the second elastic member 4 are respectively engaged with the motor push rod 23 and the motor primary 21, when the driver does not step on the pedal 101 and the pedal feel simulator 100 is in the initial position, two ends of the first elastic member 3 are respectively abutted against the inner wall of the housing 1 and the second end 23b of the motor push rod 23, and two ends of the second elastic member 4 are respectively abutted against the motor push rod 23 and the motor primary 21, or two ends of the first elastic member 3 are respectively abutted against the inner wall of the housing 1 and the second end 23b of the motor push rod 23, and one end of the second elastic member 4 is abutted against one of the motor push rod 23 and the motor primary 21, and the other end is spaced from the other one of the motor push rod 23 and the motor primary 21, or one end of the first elastic member 3 is abutted against one of the inner wall of the housing 1 and the second end 23b of the motor push rod 23, The other end is arranged at an interval with the other one of the inner wall of the shell 1 and the second end 23b of the motor push rod 23, and the two ends of the second elastic piece 4 are respectively butted against the motor push rod 23 and the motor primary 21.
When the driver does not step on the pedal 101 and the pedal feel simulator 100 is in the initial position, the states of the first elastic member 3 and the second elastic member 4 can be set according to actual requirements. For example, the first elastic member 3 and the second elastic member 4 may be both in a natural state (i.e., neither the first elastic member 3 nor the second elastic member 4 is pre-compressed), or the first elastic member 3 and the second elastic member 4 may be both in a pre-compressed state, or one of the first elastic member 3 and the second elastic member 4 may be in a pre-compressed state and the other one may be in a natural state.
According to the pedal feel simulator 100 for the vehicle of the embodiment of the invention, by providing the linear motor 2, the first elastic member 3 and the second elastic member 4, the first elastic member 3 and/or the second elastic member 4 can apply an elastic force to the motor push rod 23 to provide a basic pedal reaction force, the motor secondary 22 can apply an acting force to the motor push rod 23 to provide a compensation force, so that the pedal feel simulator 100 can provide an optimal target pedal reaction force to the pedal 101, and thus the optimal target pedal reaction force, pedal braking force and the running state of the real vehicle are matched with each other, and when the pedal feel simulator 100 is applied to the vehicle, an electric signal can be used to transmit a braking signal, the signal transmission is rapid, the braking response is rapid, the reaction is sensitive, and simultaneously a good "braking feel", especially the pedal braking feel, can be provided for the driver, so that the "braking feel" better conforms to the human body, thereby improving the braking effect of the braking system of the vehicle (for example, the braking response time is shortened, the braking force is more reasonable) and the braking feeling of the driver; the second elastic piece 4 and the first elastic piece 3 are respectively arranged at two axial sides of the primary motor 21, so that the first elastic piece 3 and the second elastic piece 4 are arranged at intervals, and the first elastic piece 3 and the second elastic piece 4 do not interfere with each other and work independently; by arranging the elastic characteristic lines of the first elastic part 3 and the second elastic part 4, the combined elastic characteristic line after the first elastic part 3 and the second elastic part 4 are superposed has diversity, so that the combined elastic characteristic line is closer to a pedal target curve, namely the elastic force of the combined elastic part is closer to the optimal target pedal reaction force, the design requirement is more easily met, the burden of the linear motor 2 is reduced, meanwhile, when any one of the first elastic part 3 and the second elastic part 4 breaks down, the other one can continuously provide the elastic force to ensure the normal operation of the pedal feeling simulator 100, the safety factor is improved, the use reliability of the pedal feeling simulator 100 is ensured, the safety of a driver is ensured, the regulation and control of the pedal braking feeling can be realized, for example, the optimal target pedal can be changed, so that different requirements of different drivers on the brake feeling are met, the adjustment is convenient; the pedal feel simulator 100 has strong integrity, can realize modular design, and is convenient to produce, transport, install and use.
In some alternative embodiments of the present invention, the inner wall of the housing 1 is provided with a first mounting protrusion 121, and one end of the first elastic member 3 is sleeved and fixed on the first mounting protrusion 121. For example, in the example of fig. 1 and 4, the first mounting protrusion 121 may be disposed on the bottom wall of the housing 1, and the first mounting protrusion 121 may be formed by a portion of the inner wall of the bottom wall protruding toward the direction close to the motor push rod 23, and the lower end (e.g., the lower end in fig. 1) of the first elastic member 3 is sleeved outside the first mounting protrusion 121, at this time, the lower end of the first elastic member 3 may be adapted to the outer peripheral wall of the first mounting protrusion 121, so that the first mounting protrusion 121 may position the first elastic member 3, and it is avoided that the first elastic member 3 cannot provide elastic force better due to the position change of the first elastic member 3, thereby further ensuring the pedal braking feeling.
Further, the second end 23b of the motor push rod 23 is provided with a second mounting protrusion 231, and the other end of the first elastic member 3 is sleeved and fixed on the outer peripheral wall of the second mounting protrusion 231. For example, as shown in fig. 1 and 4, the second mounting protrusion 231 extends toward the first mounting protrusion 121, the second mounting protrusion 231 may be coaxially disposed with the first mounting protrusion 121, an upper end (e.g., an upper end as shown in fig. 1) of the first elastic member 3 is sleeved outside the second mounting protrusion 231, and an upper end of the first elastic member 3 may be fitted with an outer peripheral wall of the second mounting protrusion 231, so that the second mounting protrusion 231 may further position the first elastic member 3.
Wherein, the cross-sectional area of the first mounting protrusion 121 may gradually increase from top to bottom, and the cross-sectional area of the second mounting protrusion 231 may gradually increase from bottom to top, thereby facilitating the mounting of the first elastic member 3. For example, the first and second mounting protrusions 121 and 231 may be formed in a circular truncated cone shape. It is understood that the cross-sectional area of the first mounting protrusion 121 may also be constant from top to bottom, and the cross-sectional area of the second mounting protrusion 231 may also be constant from top to bottom, but is not limited thereto. For example, in the example of fig. 1 and 4, the first mounting protrusion 121 and the second mounting protrusion 231 may each have a groove formed thereon, so as to reduce the material consumption of the first mounting protrusion 121 and the second mounting protrusion 231 and reduce the cost while ensuring the positioning effect of the first mounting protrusion 121 and the second mounting protrusion 231 on the first elastic member 3.
It is understood that the first elastic member 3 and the second elastic member 4 may be both springs, but are not limited thereto. When the first elastic member 3 and the second elastic member 4 are both springs, the springs may be linear springs, non-linear springs, and the like, and the inner diameters of the springs may be constant along the axial direction of the springs, or may gradually increase or decrease along the axial direction of the springs, for example, the springs may be cylindrical springs or conical springs, and the stiffness coefficients of the springs may be the same or different. The first elastic piece 3 and the second elastic piece 4 can be coaxially mounted, and a first elastic force applied to the motor push rod 23 by the first elastic piece 3 and a second elastic force applied to the motor push rod 23 by the second elastic piece 4 are guaranteed to be balanced.
In addition, when the pedal feel simulator 100 is applied to a vehicle, the pedal feel simulator 100 is in the initial position when the driver does not step on the pedal 101, and the state and the starting time of the first elastic member 3 and the state and the starting time of the second elastic member 4 can be set according to actual requirements. For example, when the pedal feel simulator 100 is in the initial position, the first elastic element 3 and the second elastic element 4 are both in the pre-compression state, that is, the first elastic element 3 and the second elastic element 4 are both in the compression state to generate the acting force on the motor push rod 23; when the driver steps on the pedal 101, the first elastic member 3 and the second elastic member 4 operate simultaneously. Or, when the pedal feel simulator 100 is in the initial position, the first elastic element 3 is in the pre-compression state, and the second elastic element 4 is in the natural state, at this time, the first elastic element 3 generates an acting force on the motor push rod 23, the second elastic element 4 does not generate an acting force on the motor push rod 23, and one end of the second elastic element 4 and the corresponding motor push rod 23 or the corresponding motor primary 21 may abut against each other or may be disposed at intervals; when the pedal feel simulator 100 is in the initial position and one end of the second elastic member 4 abuts against the corresponding motor push rod 23 or the corresponding motor primary 21, the driver steps on the pedal 101, and the displacement of the pedal 101 is greater than zero, the first elastic member 3 and the second elastic member 4 operate simultaneously, or when the pedal feel simulator 100 is in the initial position and one end of the second elastic member 4 is spaced from the corresponding motor push rod 23 or the corresponding motor primary 21, the displacement of the pedal 101 reaches the set value, or the displacement of the motor push rod 23 reaches the set value, the first elastic member 3 and the second elastic member 4 operate simultaneously, and the displacement of the pedal 101 does not reach the set value, or the displacement of the motor push rod 23 does not reach the set value, only the first elastic member 3 operates. For another example, when the pedal feel simulator 100 is at the initial position, the first elastic element 3 and the second elastic element 4 are both in a natural state, and at this time, the first elastic element 3 and the second elastic element 4 both do not apply an elastic force to the motor push rod 23, both ends of the first elastic element 3 may respectively abut against the second end 23b of the motor push rod 23 and the inner wall of the housing 1, one end of the second elastic element 4 may abut against the motor primary 21, and the other end may abut against or be spaced from the motor push rod 23. But is not limited thereto.
Alternatively, as shown in fig. 1 and 4, the second mounting protrusion 231 is fixedly mounted on the motor push rod 23 by a mounting screw 232, and the mounting screw 232 may pass through the second mounting protrusion 231 from bottom to top to fixedly mount the second mounting protrusion 231 on the second end 23b of the motor push rod 23.
