Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a throttle device and a vehicle. Background Technology

[0002] Vehicles such as electric bikes and motorcycles have become one of the main modes of transportation in cities due to their ease of operation and parking. In related technologies, users can operate a throttle mechanism on the vehicle to accelerate, stop, or brake. However, the component arrangement in the throttle mechanism in these technologies is unreasonable, resulting in a large radial dimension. Furthermore, the throttle mechanism is prone to component interference during assembly, leading to low assembly efficiency. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a throttle device that helps reduce its radial dimension and makes it less likely for the components inside the throttle device to interfere with each other during assembly, thereby improving assembly efficiency and reliability after assembly.

[0005] An embodiment of this utility model also proposes a vehicle.

[0006] The throttle device of this utility model includes: a bracket, a rotor, a first elastic element, and a second elastic element. The rotor passes through the bracket and can rotate forward and backward relative to the bracket. A receiving space is defined between the rotor and the bracket. The first elastic element and the second elastic element are arranged at intervals along the axial direction of the rotor within the receiving space. After the rotor rotates forward relative to the bracket, the first elastic element can reset the rotor to its initial position. After the rotor rotates backward relative to the bracket, the second elastic element can reset the rotor to its initial position.

[0007] According to the embodiment of the present invention, the throttle device has a reduced radial dimension because the first elastic element and the second elastic element are arranged sequentially along the axial direction of the rotor in the accommodating space. Compared with the scheme of "the first elastic element and the second elastic element are arranged radially along the rotor", the first elastic element and the second elastic element are arranged at intervals along the axial direction of the rotor, which can prevent the first elastic element and the second elastic element from interfering with each other during the assembly process, thereby improving the assembly efficiency and reliability of the throttle device after assembly.

[0008] In some embodiments, the elastic coefficient of the second elastic element is greater than that of the first elastic element.

[0009] In some embodiments, one of the support and the rotor is provided with a partition portion, the partition portion being disposed within the receiving space, and the first elastic member and the second elastic member being respectively arranged on both sides of the partition portion along the axial direction of the rotor.

[0010] In some embodiments, the partition is disposed on the bracket, and both the first elastic member and the second elastic member are connected to the partition.

[0011] In some embodiments, the first elastic element includes a first torsion spring, which is sleeved on the rotor, with a first end of the first torsion spring connected to the rotor and a second end of the first torsion spring connected to the bracket.

[0012] In some embodiments, the first end of the rotor passes through the bracket, and the throttle device further includes a limiting plate. The limiting plate is installed at the first end of the rotor and cooperates with the bracket. When the rotor rotates in the forward direction relative to the bracket, the limiting plate is fixed relative to the bracket. When the rotor rotates in the reverse direction relative to the bracket, the rotor is fixed relative to the limiting plate and rotates synchronously. The first end of the second elastic member is connected to the limiting plate, and the second end of the second elastic member is connected to the bracket.

[0013] In some embodiments, the second elastic element includes a second torsion spring, which is sleeved on the rotor.

[0014] In some embodiments, the limiting disk is provided with a first slide rail, the first slide rail having a first wall and a second wall arranged opposite to each other along the circumference of the limiting disk, the rotor having a first protrusion, the first protrusion sliding in the first slide rail in the direction toward the second wall when the rotor rotates in the forward direction relative to the support, and the first protrusion abutting against the first wall when the rotor rotates in the reverse direction relative to the support, so that the rotor and the limiting disk rotate synchronously.

[0015] In some embodiments, the first end of the rotor has a positioning flange that is connected to the first end face of the limiting disk, and the bracket is connected to the second end face of the limiting disk.

[0016] In some embodiments, the bracket is provided with a second slide rail, the second slide rail having a third wall and a fourth wall along the circumference of the bracket, the limiting plate having a second protrusion, the second protrusion being arranged adjacent to the third wall when the rotor rotates in the forward direction relative to the bracket, and the second protrusion being able to slide in the second slide rail in the direction toward the fourth wall when the rotor rotates in the reverse direction relative to the bracket.

[0017] In some embodiments, the bracket has a first stop block and a second stop block, which are located within the receiving space and are arranged circumferentially spaced along the bracket. The rotor has a limiting boss, which abuts against the first stop block when the rotor rotates forward from the initial position to the first limit position, and abuts against the second stop block when the rotor rotates backward from the initial position to the second limit position.

[0018] In some embodiments, the rotation angle range of the rotor between the initial position and the first limit position is θ1, and the rotation angle range of the rotor between the initial position and the second limit position is θ2, wherein θ1 > θ2.

[0019] In some embodiments, the throttle device includes a Hall sensor and a magnetic element. The Hall sensor is disposed on the bracket, and the magnetic element is disposed on the rotor. The Hall sensor cooperates with the magnetic element. The Hall sensor can output a first signal when the rotor rotates in the forward direction and output a second signal when the rotor rotates in the reverse direction. The first signal is used to accelerate the vehicle, and the second signal is used to brake or reverse the vehicle.

[0020] Another embodiment of the vehicle of the present invention includes the throttle device described in any one of the embodiments of the present invention.

[0021] According to the embodiments of the present invention, since the first elastic member and the second elastic member are arranged sequentially along the axial direction of the rotor in the accommodating space, the radial dimension of the throttle device can be reduced compared to the scheme of "the first elastic member and the second elastic member are arranged radially along the rotor". Furthermore, since the first elastic member and the second elastic member are arranged at intervals along the axial direction of the rotor, interference between the first elastic member and the second elastic member during assembly can be prevented, thereby improving the assembly efficiency and reliability of the throttle device of the vehicle.

[0047] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0048] The following is a reference appendix. Figures 1 to 16 This invention describes a throttle device and a vehicle according to embodiments of the present invention.

[0049] like Figures 1 to 6 As shown, the throttle device 10 of this utility model embodiment includes: a bracket 1, a rotor 2, a first elastic element 3 and a second elastic element 4. The rotor 2 passes through the bracket 1 and can rotate in the forward and reverse directions relative to the bracket 1. A receiving space 11 is defined between the rotor 2 and the bracket 1. The first elastic element 3 and the second elastic element 4 are arranged at intervals along the axial direction of the rotor 2 in the receiving space 11.

[0050] After the rotor 2 rotates forward relative to the support 1, the first elastic element 3 can reset the rotor 2 to the initial position. After the rotor 2 rotates in the opposite direction relative to the support 1, the first elastic element 3 and the second elastic element 4 can work together to reset the rotor 2 to the initial position.

[0051] According to the embodiment of the present invention, the throttle device 10 has a reduced radial dimension because the first elastic element 3 and the second elastic element 4 are arranged at intervals along the axial direction of the rotor 2 in the accommodating space 11. Compared with the scheme of "the first elastic element 3 and the second elastic element 4 are arranged radially along the rotor 2", the first elastic element 3 and the second elastic element 4 are arranged sequentially along the axial direction of the rotor 2, which can prevent the first elastic element 3 and the second elastic element 4 from interfering with each other during the assembly process, thereby improving the assembly efficiency and reliability of the throttle device 10 after assembly.

[0052] like Figure 5 and Figure 8 As shown, the first elastic element 3 and the second elastic element 4 are spaced apart along the axial direction of the rotor 2. It is understood that there is an installation gap between the first elastic element 3 and the second elastic element 4. Compared to the scheme where "the first elastic element 3 and the second elastic element 4 abut against each other along the axial direction of the rotor 2," this arrangement further avoids interference between the first elastic element 3 and the second elastic element 4 during assembly or actual use, thus improving the assembly efficiency and reliability of the throttle device 10 after assembly.

[0053] It is understandable that the initial position is the position that the rotor 2 and the support 1 maintain when there is no force or under normal conditions.

[0054] When the rotor 2 rotates forward relative to the support 1, the first elastic element 3 will deform and store energy. Under the action of the first elastic element 3, the rotor 2 can automatically reset to the initial position, thus meeting the requirement that the rotor 2 automatically resets after rotating forward.

[0055] When the rotor 2 rotates in the opposite direction relative to the support 1, the second elastic element 4 will deform and store energy. Under the combined action of the second elastic element 4, the rotor 2 can automatically reset to the initial position, thus meeting the requirement that the rotor 2 automatically resets after rotating in the opposite direction.

[0056] Optionally, the first elastic element 3 and the second elastic element 4 can work together to reset the rotor 2 to its initial position. That is, when the rotor 2 rotates in the opposite direction relative to the support 1, the first elastic element 3 and the second elastic element 4 deform simultaneously and store energy. Under the combined action of the first elastic element 3 and the second elastic element 4, the rotor 2 can automatically reset to its initial position, thus meeting the requirement for the rotor 2 to automatically reset after reverse rotation. Therefore, the magnitude of the elastic force that the rotor 2 needs to overcome in forward and reverse rotation can be different, thus adapting to the needs of acceleration, braking, reversing, etc.

[0057] In addition, the second elastic element 4 can also counteract the elastic force of the first elastic element 3, so that the rotor 2 can be kept in the initial position under the combined elastic action of the first elastic element 3 and the second elastic element 4, which is beneficial to improving the stability of the rotor 2 in the initial position.

[0058] For example, the elastic coefficient of the second elastic element 4 is greater than that of the first elastic element 3. That is, the elastic force of the second elastic element 4 can be a multiple of the elastic force of the first elastic element 3, specifically 1.5 times, 2 times, 3 times, 4 times, etc., to meet the requirement that the second elastic element 4 counteracts the elastic force of the first elastic element 3 when the rotor 2 is in the initial position.

[0059] The axial spacing between the first elastic element 3 and the second elastic element 4 can be designed as needed according to the length of the throttle device 10, and this utility model does not limit this.

[0060] Optionally, such as Figure 5 and Figure 8 As shown, a partition 12 is provided on one of the bracket 1 and the rotor 2. The partition 12 is located within the receiving space 11. The first elastic member 3 and the second elastic member 4 are respectively arranged on both sides of the partition 12 along the axial direction of the rotor 2. Under the limiting action of the partition 12, the first elastic member 3 and the second elastic member 4 can be isolated from each other during both the assembly process and the operation of the throttle device 10, which can effectively prevent interference between the first elastic member 3 and the second elastic member 4 and improve the reliability of the throttle device 10 after assembly.

[0061] like Figure 5 and Figure 8 As shown, the partition 12 can divide the receiving space 11 into left and right chambers. The first elastic member 3 can be inserted into the right chamber of the partition 12 from the right side of the bracket 1, and the second elastic member 4 can be inserted into the left chamber of the partition 12 from the left side of the bracket 1.

[0062] Optionally, such as Figure 5 and Figure 8 As shown, the partition 12 is provided on the bracket 1, and the first elastic member 3 and the second elastic member 4 are both connected to the partition 12. Since the first elastic member 3 and the second elastic member 4 are both connected to the partition 12, the partition 12 can both isolate the first elastic member 3 and the second elastic member 4 and fix the first elastic member 3 and the second elastic member 4, thereby improving the convenience of assembling the first elastic member 3 and the second elastic member 4.

[0063] like Figure 5 , Figure 6 and Figure 8 As shown, the partition 12 is generally annular in structure and is located on the inner wall of the support 1. There is an installation gap between the inner wall surface of the partition 12 and the inner wall surface of the rotor 2 so that the rotor 2 can rotate relative to the partition 12.

[0064] like Figure 7 As shown, the partition 12 is provided with a mounting hole 121. The end of the first elastic member 3 and the end of the second elastic member 4 can be inserted into the mounting hole 121 on the partition 12 to fix the first elastic member 3 and the second elastic member 4, thereby improving the convenience of assembling the first elastic member 3 and the second elastic member 4.

[0065] Optionally, such as Figure 8 and Figure 9As shown, the first elastic element 3 includes a first torsion spring 31, which is sleeved on the rotor 2. The first end of the first torsion spring 31 is connected to the rotor 2, and the second end of the first torsion spring 31 is connected to the bracket 1. Thus, the first torsion spring 31 can store energy when the rotor 2 rotates in both the forward and reverse directions. When the rotor 2 is released, the first torsion spring 31 can reset the rotor 2 to its initial position.

[0066] Furthermore, since the first elastic element 3 is a torsion spring, compared with solutions such as "the first elastic element 3 is a cylindrical spring and a coil spring", the torsion spring can provide more precise torque to the rotor 2, resulting in higher reliability during operation.

[0067] Optionally, such as Figure 5 , Figure 8 and Figure 9 As shown, the first end of the rotor 2 passes through the bracket 1. The throttle device 10 also includes a limiting disk 5. The limiting disk 5 is installed at the first end of the rotor 2 and cooperates with the bracket 1. When the rotor 2 rotates in the forward direction relative to the bracket 1, the limiting disk 5 is fixed relative to the bracket 1. When the rotor 2 rotates in the reverse direction relative to the bracket 1, the rotor 2 is fixed relative to the limiting disk 5 and rotates synchronously. The first end of the second elastic member 4 is connected to the limiting disk 5, and the second end of the second elastic member 4 is connected to the bracket 1.

[0068] Since the first end of the second elastic element 4 is connected to the limiting disk 5 and the second end of the second elastic element 4 is connected to the bracket 1, when the rotor 2 rotates forward relative to the bracket 1, the limiting disk 5 and the bracket 1 are relatively fixed, so the shape of the second elastic element 4 can remain unchanged. That is to say, when the rotor 2 rotates forward, the first elastic element 3 can deform to store energy, while the shape of the second elastic element 4 remains unchanged. Therefore, when the external force on the rotor 2 is released, the first elastic element 3 can drive the rotor 2 to reset from the forward rotation position to the initial position.

[0069] When rotor 2 rotates in the opposite direction to support 1, rotor 2 and limiting disk 5 are relatively fixed and rotate synchronously. This causes rotor 2 to synchronously drive limiting disk 5 to rotate. As limiting disk 5 rotates, relative rotation occurs between support 1 and limiting disk 5, resulting in elastic deformation of the second elastic element 4. Simultaneously, the first elastic element 3 also undergoes elastic deformation due to the relative rotation of rotor 2 and support 1. Therefore, when the external force on rotor 2 is released, the first elastic element 3 and the second elastic element 4 can drive rotor 2 to return from the reverse rotation position to its initial position.

[0070] The throttle device 10 of this utility model sets a limiting plate 5 so that the second elastic element 4 only undergoes elastic deformation when the rotor 2 rotates in the reverse direction, and can maintain its shape when the rotor 2 rotates in the forward direction. This simplifies the internal parts of the throttle device 10, requires fewer parts, and is easy to process and assemble.

[0071] Optionally, such as Figure 8 and Figure 9 As shown, the second elastic element 4 includes a second torsion spring 41, which is sleeved on the rotor 2. The second torsion spring 41 can store energy only when the rotor 2 rotates in the reverse direction. Since the second elastic element 4 is a torsion spring, compared with solutions such as "the second elastic element 4 is a cylindrical spring or a coil spring", the torsion spring can provide more precise torque to the rotor 2, resulting in higher reliability during operation.

[0072] In addition, since both the first elastic element 3 and the second elastic element 4 are torsion springs, it is easy for the operator to install them in the receiving space 11, and it can reduce the occupation of the radial space of the throttle device 10, resulting in better actual use.

[0073] Optionally, such as Figures 10 to 13 As shown, the limiting disk 5 is provided with a first slide 51. The first slide 51 has a first wall surface 511 and a second wall surface 512 arranged opposite to each other along the circumference of the limiting disk 5. The rotor 2 has a first protrusion 21. When the rotor 2 rotates in the forward direction relative to the support 1, the first protrusion 21 can slide in the first slide 51 in the direction toward the second wall surface 512. When the rotor 2 rotates in the reverse direction relative to the support 1, the first protrusion 21 abuts against the first wall surface 511 so that the rotor 2 and the limiting disk 5 rotate synchronously.

[0074] It is understandable that when the rotor 2 rotates in the forward direction, since the first protrusion 21 can slide in the first slide rail 51 in the direction toward the second wall 512, the limiting disk 5 will not obstruct the rotation of the rotor 2. That is, the limiting disk 5 can remain stationary with the bracket 1 when the rotor 2 rotates in the forward direction, and the second elastic member 4 will not undergo elastic deformation at this time.

[0075] When the rotor 2 rotates in the reverse direction, the first protrusion 21 abuts against the first wall surface 511. Therefore, under the limiting action of the first protrusion 21 and the first wall surface 511, the limiting disk 5 will rotate synchronously with the rotor 2. When the limiting disk 5 rotates, the bracket 1 and the limiting disk 5 will rotate relative to each other, and the second elastic element 4 will undergo elastic deformation.

[0076] Therefore, the throttle device 10 of this utility model can achieve the following functions with a simple structure by adopting the above-described structure for the limiting disc 5 and the rotor 2: when the rotor 2 rotates in the forward direction, the first elastic element 3 stores energy while the second elastic element 4 remains unchanged in shape; when the rotor 2 rotates in the reverse direction, both the first elastic element 3 and the second elastic element 4 store energy.

[0077] For example, such as Figure 13As shown, there are two sets of first slide rails 51, and the two sets of first slide rails 51 are arranged at intervals along the circumference of the limiting disk 5. There are two first protrusions 21, and the two first protrusions 21 are arranged at intervals along the circumference of the rotor 2. The two first protrusions 21 are matched one-to-one in the two first slide rails 51.

[0078] Optionally, such as Figure 5 As shown, the first end of the rotor 2 has a positioning flange 22, which is connected to the first end face of the limiting disk 5, and the bracket 1 is connected to the second end face of the limiting disk 5. It can be understood that the positioning flange 22 and the bracket 1 can respectively axially limit the two end faces of the limiting disk 5 in the thickness direction. The throttle device 10 of this embodiment connects the rotor 2, the bracket 1, and the limiting disk 5 in the above manner, eliminating the need for additional fasteners. It can be assembled together solely through the structures of the rotor 2, the bracket 1, and the limiting disk 5, simplifying the structure of the throttle device 10 and improving the ease of assembly.

[0079] like Figure 11 and Figure 12 As shown, the positioning flange 22 is arranged circumferentially around the first end of the rotor 2, and the radial outer end of the positioning flange 22 is a hook structure to facilitate the assembly and positioning of the limiting disk 5.

[0080] Optionally, such as Figure 4 and Figure 7 As shown, the support 1 is provided with a second slide rail 13. The second slide rail 13 has a third wall surface 131 and a fourth wall surface 132 along the circumference of the support 1. The limiting disk 5 has a second protrusion 52. When the rotor 2 rotates forward relative to the support 1, the second protrusion 52 is arranged adjacent to the third wall surface 131. When the rotor 2 rotates in the opposite direction relative to the support 1, the second protrusion 52 can slide in the second slide rail 13 in the direction toward the fourth wall surface 132. It can be understood that the second slide rail 13 can positionally constrain the range of motion of the second protrusion 52. When the rotor 2 rotates in the opposite direction to its limit position, the second protrusion 52 can abut against the fourth wall surface 132. Thus, by designing the length of the second slide rail 13, the range of motion of the rotor 2 in the opposite direction can be limited. In addition, when the rotor 2 rotates forward, the second protrusion 52 can abut against the third wall surface 131 to limit the relative rotation of the second protrusion 52 with respect to the support 1, thereby keeping the shape of the second elastic member 4 unchanged.

[0081] For example, there are two sets of second slide rails 13, and the two sets of second slide rails 13 are arranged at intervals along the circumference of the bracket 1. There are two second protrusions 52, and the two second protrusions 52 are arranged at intervals along the circumference of the limiting plate 5. The two second protrusions 52 are matched one-to-one in the two second slide rails 13.

[0082] like Figure 4As shown, the central angle α corresponding to a single second slide rail 13 is 30°, which limits the angle range of the rotor 2 to within 30°, thus meeting the usage requirements of the throttle device 10.

[0083] Optionally, such as Figure 3 As shown, the bracket 1 has a first stop block 14 and a second stop block 15. The first stop block 14 and the second stop block 15 are located in the receiving space 11 and are arranged at intervals along the circumference of the bracket 1. The rotor 2 has a limiting boss 23. When the rotor 2 rotates from the initial position to the first limit position, the limiting boss 23 abuts against the first stop block 14. When the rotor 2 rotates from the initial position to the second limit position, the limiting boss 23 abuts against the second stop block 15.

[0084] Understandably, the first stop block 14 and the second stop block 15 can bidirectionally limit the forward and reverse rotation of the rotor 2. When the rotor 2 rotates forward to the first limit position, the limiting boss 23 abuts against the first stop block 14 to restrict the rotor 2 from continuing to rotate forward. When the rotor 2 rotates in the reverse direction to the second limit position, the limiting boss 23 abuts against the second stop block 15 to restrict the rotor 2 from continuing to rotate in the reverse direction. This prevents the throttle device 10 from exceeding the limit position when rotating forward or in the reverse direction, improving the reliability of the throttle device 10 during rotation.

[0085] Optionally, such as Figure 3 As shown, the rotation angle range of rotor 2 from the initial position to the first limit position is θ1, and the rotation angle range of rotor 2 from the initial position to the second limit position is θ2, where θ1 > θ2. This allows the forward and reverse rotation strokes of rotor 2 to be adapted to actual usage conditions, resulting in a better user experience.

[0086] For example, θ1 (i.e., the forward rotation angle range of rotor 2) can be selected between 45° and 55°. For example, θ1 can be 45°, 50°, or 55°. θ2 (i.e., the reverse rotation angle range of rotor 2) can be selected between 25° and 35°. For example, θ2 can be 25°, 30°, or 35°.

[0087] Optionally, such as Figure 3 and Figure 5 As shown, the throttle device 10 includes a Hall sensor 61 and a magnetic element 62. The Hall sensor 61 is mounted on the bracket 1, and the magnetic element 62 is mounted on the rotor 2. The Hall sensor 61 and the magnetic element 62 cooperate with each other. The Hall sensor 61 can output a first signal when the rotor 2 rotates in the forward direction and output a second signal when the rotor 2 rotates in the reverse direction. The first signal is used to accelerate the vehicle, and the second signal is used to brake or reverse the vehicle, thereby meeting the needs of vehicle acceleration, braking, and reversing.

[0088] like Figure 3 and Figure 5 As shown, the width of the gap between the Hall sensor 61 and the magnetic component 62 in the radial direction of the bracket 1 is 0.8 mm to 1 mm, which avoids interference between the Hall sensor 61 and the magnetic component 62 and ensures that the two can generate a good sensing signal.

[0089] like Figure 3 As shown, the magnetic component 62 is a tile-shaped magnet. The magnetic component 62 extends circumferentially along the rotor 2, and the central angle corresponding to the arc length of the magnetic component 62 is 80°. When the rotor 2 rotates from the initial position to the first extreme position, the angle range between the Hall sensor 61 and the magnetic component 62 is 50°. When the rotor 2 rotates from the initial position to the second extreme position, the angle range between the Hall sensor 61 and the magnetic component 62 is 30°. In other words, the forward rotation angle of the rotor 2 is 50°, and the reverse rotation angle is 30°, thus ensuring that the forward and reverse rotation strokes of the rotor 2 are adapted to actual usage conditions, resulting in a better user experience.

[0090] For example, such as Figure 6 and Figure 9 As shown, the limiting boss 23 is provided with a mounting groove 231, and the magnetic component 62 is fitted in the mounting groove 231. The magnetic component 62 and the mounting groove 231 can be fitted by snap-fit, adhesive or screw connection, and this utility model does not limit the method of fitting.

[0091] like Figure 14 and Figure 15 As shown, the throttle device 10 also includes a cover plate 63 and a connecting harness 64. After the Hall sensor 61 is installed on the bracket 1, the cover plate 63 can be connected to the bracket 1 to cover the Hall sensor 61. One end of the connecting harness 64 is connected to the Hall sensor 61, and the other end of the connecting harness 64 is led out to the outside of the bracket 1.

[0092] like Figure 16 As shown, another embodiment of the present invention includes a vehicle with the throttle device 10 of the present invention. The vehicle can be an electric vehicle, an electric bicycle, or a motorcycle, etc.

[0093] According to the embodiment of the present invention, since the first elastic member 3 and the second elastic member 4 are arranged at intervals along the axial direction of the rotor 2 in the accommodating space 11, the radial dimension of the throttle device 10 can be reduced compared to the scheme of "the first elastic member 3 and the second elastic member 4 are arranged radially along the rotor 2". Furthermore, since the first elastic member 3 and the second elastic member 4 are arranged sequentially along the axial direction of the rotor 2, interference between the first elastic member 3 and the second elastic member 4 during assembly can be prevented, thereby improving the assembly efficiency and reliability of the throttle device 10 of the vehicle.

[0094] like Figure 16 As shown, the vehicle includes an instrument cluster 20, a motor control assembly 30, a vehicle control system 40, and a central control system. The central control system is located at one of the instrument cluster 20, the motor control assembly 30, or the vehicle control system 40. The instrument cluster 20 can be located at the front of the vehicle, and the vehicle control system 40 (VCU) can also be located at the front of the vehicle. The motor control assembly 30 can be located at the vehicle seat, and it is mainly used to control the rotation of the wheel hub motors 50. The central control system (hereinafter referred to as the central control) can be located in the instrument cluster 20, the motor control assembly 30, or the vehicle control system 40, thereby improving the flexibility and convenience of the central control layout.
