[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0053] Now more and more people go to professional fitness places (such as gyms, fitness studios, etc.) to exercise and exercise. At present, most of the fitness equipment configured in professional fitness places are intelligent equipment, which can detect the user's exercise status.

[0054] The resistance of current fitness equipment is generally set to a fixed value and cannot be adjusted, which makes the exercise mode relatively simple and does not achieve the best exercise effect. If the resistance of fitness equipment is to be adjusted, more accurate data about the user's exercise status is required, but current fitness equipment cannot measure more accurate data.

[0055] In view of this, the utility model provides a fitness equipment.

[0056] The fitness equipment may be an elliptical machine, a spinning bike, a climbing machine, a treadmill, etc., which are not specifically limited here.

[0057] In the embodiment of the present utility model, Figures 1 to 8 As shown, the fitness equipment includes a frame 100, a flywheel assembly 200, a first magnetic member 300, a first sensor 400 and a second sensor 500. The flywheel assembly 200 is rotatably connected to the frame 100; the first magnetic member 300 is arranged on the flywheel assembly 200; the first sensor 400 is arranged on one side of the flywheel assembly 200; the second sensor is arranged at a distance from the first sensor; wherein the first sensor is a Hall sensor 400, and the second sensor is a Hall sensor 400 or a photoelectric sensor 500; when the second sensor is a photoelectric sensor 500, a plurality of through holes 210 are provided on the flywheel assembly 200; when the second sensor is a Hall sensor 400, a plurality of second magnetic members 800 are provided on the flywheel assembly 200.

[0058] Specifically, the frame 100 is a basic supporting structure of the fitness equipment, and is used to support the seat, handles, and other components of the fitness equipment. Generally, considering that the frame 100 needs to support the user to move on the seat installed thereon, the frame 100 is set to be made of metal material, and the frame 100 can be made of iron or steel, which is not specifically limited here.

[0059] Secondly, the flywheel assembly 200 is a transmission assembly in the frame 100. The flywheel assembly 200 can rotate relative to the frame 100 by providing a driving force by the user, wherein the user can provide the driving force through a pulling device or a thrust device, or the user can provide the driving force through a pedal device. The flywheel assembly 200 can be provided with only one rotatable wheel body, or can have multiple rotatable wheel bodies, which is not specifically limited here.

[0060] Specifically, the flywheel assembly 200 at least includes a driving wheel 220 and a driven wheel 230 rotatably mounted on the frame 100. The driving wheel 220 and the driven wheel 230 are connected in transmission, and the driven wheel 230 is driven to rotate by driving the driving wheel 220. The transmission method can be belt tooth transmission, chain transmission, or gear meshing transmission. The transmission method of the driving wheel 220 and the driven wheel 230 is not specifically limited here. The magnet can be set on the driving wheel 220 or on the driven wheel 230. When the first magnetic member 300 is set on the driving wheel 220, the first sensor 400 is set on one side of the driving wheel 220; when the first magnetic member 300 is set on the driven wheel 230, the first sensor 400 is set on one side of the driven wheel 230. It is not specifically limited here.

[0061] In order to obtain the position information and speed information of the flywheel assembly 200, a first magnetic member 300 and a first sensor 400 are provided, wherein the first magnetic member 300 is provided on the flywheel assembly 200, and the first sensor 400 is provided on one side of the flywheel assembly 200. It should be noted that the first magnetic member 300 is provided on the flywheel assembly 200, that is, the first magnetic member 300 may be provided on the surface of the flywheel assembly 200, or the first magnetic member 300 may be embedded in the flywheel assembly 200, which is not specifically limited herein.

[0062] According to the working principle of the first sensor 400, the Hall voltage changes with the change of the magnetic field strength. The stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. In this embodiment, by setting the first magnetic member 300 on the flywheel assembly 200, the rotation of the flywheel assembly 200 is used as a switch to control the magnetic flux. In this way, the change of the output voltage of the Hall integrated circuit can indicate a certain position of the flywheel assembly 200.

[0063] When the flywheel assembly 200 rotates, the first magnetic member 300 on the flywheel assembly 200 can be driven to rotate together, and the first sensor 400 is set on one side of the flywheel assembly 200 and the position of the first magnetic member 300 relative to the Hall sensor is constantly changing, and then the magnetic field strength detected at the sensor changes accordingly, and the position where the first sensor 400 and the first magnetic member 300 just correspond is taken as a critical point. When the magnetic field strength detected by the sensor is consistent with the magnetic field strength at the beginning of the rotation of the flywheel assembly 200, it means that the flywheel assembly 200 has just rotated one circle. Furthermore, the time taken for the flywheel assembly 200 to rotate one circle and the speed at which the flywheel assembly 200 rotates one circle can be measured by this method, and the position of a certain part of the driving wheel 220 can also be obtained according to the position where the magnet is set.

[0064] The above method can meet the basic rotation speed measurement requirements of the flywheel assembly 200, but it is difficult to further obtain the instantaneous speed of the flywheel assembly 200 or the average rotation speed in a short period of time using only the above method.

[0065] In view of this, the fitness equipment of the present invention further includes a second sensor 500. The second sensor 500 can be configured as a photoelectric sensor or a Hall sensor.

[0066] When the second sensor 500 is set as a photoelectric sensor, the second sensor 500 includes a signal transmitting end and a signal receiving end. A through hole 210 for the signal to pass through is opened on the flywheel assembly 200. The signal transmitting end and the signal receiving end are respectively arranged on opposite sides of the flywheel assembly 200. By opening a plurality of through holes 210 on the flywheel assembly 200, the signal emitted by the signal transmitting end can pass through the through hole 210 and be received by the signal receiving end when the flywheel assembly 200 rotates.

[0067] It should be noted that the signal receiving end and the first sensor 400 can be located on one side of the flywheel assembly 200, and the signal transmitting end can be located on the other side opposite to the flywheel assembly 200; the signal transmitting end and the first sensor 400 can also be located on one side of the flywheel assembly 200, or the signal receiving end can be located on the other side opposite to the flywheel assembly 200. Among them, the number of through holes 210 opened is not specifically limited in this embodiment, but at least two through holes 210 need to be opened. Among them, the signal receiving end in this embodiment is the second sensor 500, and the signal transmitting end is the light source. Through the number of through holes 210 and the time interval for the signal transmitting end to receive the signal, the clockwise speed and the average speed in a short time can be measured. The second sensor 500 in this embodiment is an infrared sensor, and of course it can also be a laser sensor.

[0068] When the second sensor 500 is set as a Hall sensor, a plurality of second magnetic members 800 should also be provided on the flywheel assembly 200. At this time, the principle of the second sensor 500 is the same as that of the first sensor 400, but a plurality of second magnetic members 800 are provided, so that the interval of the magnetic field change sensed by the second sensor 800 is longer, thereby the average speed and instantaneous speed in a short time can be measured.

[0069] The fitness equipment can predict the time required for the second sensor 500 to reach the next through hole 210 based on the number of through holes 210 and the position information measured by the first sensor 400, combined with the instantaneous speed measured by the second sensor 500, thereby judging the real-time motion state of the user. When the user's motion state is good, the resistance of the fitness equipment is increased, and when the user's motion state is poor, the resistance of the fitness equipment is reduced, thereby providing intelligent motion services for the user.

[0070] The technical solution of the utility model adopts a method in which a first magnetic member 300 is provided on the flywheel assembly 200 of the fitness equipment, and a first sensor 400 is provided on one side of the flywheel assembly 200 corresponding to the first magnetic member 300, so as to measure the position information of the flywheel assembly 200, and then the instantaneous speed information is measured by the second sensor 500 to judge the user's exercise state, and the resistance of the fitness equipment is adjusted in real time according to the user's exercise state, so as to provide the user with intelligent exercise services.

[0071] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 5 The flywheel assembly 200 includes a driving wheel 220 and a driven wheel 230 rotatably mounted on the frame 100, the driving wheel 220 and the driven wheel 230 are transmission-connected, and the plurality of through holes 210 are provided on the driving wheel 220, or the plurality of through holes 210 are provided on the driven wheel 230.

[0072] In this embodiment, there are two ways to open the through holes 210. One is to open multiple through holes 210 on the driving wheel 220, and then the signal transmitting end and the signal receiving end are arranged on the opposite sides of the driving wheel 220; the other way is to open multiple through holes 210 on the driven wheel 230, and then the signal transmitting end and the signal receiving end are arranged on the opposite sides of the driven wheel 230. The above two embodiments are both within the protection scope of this embodiment.

[0073] In one embodiment, see Figure 2 and Figure 3 The first magnetic member 300 is arranged on the driving wheel 220, and the first sensor 400 is arranged on one side of the driving wheel 220; the signal transmitting end and the signal receiving end are respectively arranged on opposite sides of the driving wheel 220, and the multiple through holes 210 are arranged at intervals along the circumference of the driving wheel 220.

[0074] According to the above-mentioned embodiment, in this embodiment, the first magnetic member 300 is arranged on the driving wheel 220, the first sensor 400 is arranged on one side of the driving wheel 220, and the signal transmitting end and the signal receiving end are respectively arranged on opposite sides of the driving wheel 220. In this embodiment, the first sensor 400 and the second sensor 500 are used to measure the rotation speed information and position information of the driving wheel 220 respectively. The multiple through holes 210 opened on the driving wheel 220 are arranged at intervals along the circumference of the driving wheel 220. In this way, the signal emitted by the signal transmitting end can be received by the signal receiving end through all the through holes 210 after the driving wheel 220 rotates one circle. The multiple through holes 210 are arranged at intervals, so that the signal reception has breakpoints, and the signal emitted uninterruptedly by the signal transmitting end can be divided into multiple signals to be received by the signal receiving end, so that the time information of the signal transmitting end and the signal receiving end from a corresponding through hole 210 to another corresponding adjacent through hole 210 can be measured.

[0075] In one embodiment, see Figure 2 and Figure 3 , the plurality of through holes 210 are arranged at equal intervals along the circumference of the driving wheel 220. Considering that in order to accurately measure the instantaneous rotation speed of the driving wheel 220 and the accurate average speed of the driving wheel 220 within one rotation, the plurality of through holes 210 are arranged at equal intervals along the circumference of the driving wheel 220. Such an arrangement can make the time interval from one through hole 210 corresponding to the second sensor 500 to the adjacent through hole 210 corresponding to the second sensor 500 equal when the rotation speed of the driving wheel 220 is stable.

[0076] In one embodiment, see Figure 2 and Figure 3 The plurality of through holes 210 are arranged close to the outer peripheral wall of the driving wheel 220 .

[0077] Furthermore, considering that, when the driving wheel 220 rotates, there should be an obvious time interval between the signal receiving end and the signal transmitting end corresponding to one through hole 210 and the signal receiving end and the signal transmitting end corresponding to the adjacent through hole 210. If multiple through holes 210 are arranged at a position close to the axis of the driving wheel 220, the time interval between the signal receiving end and the signal transmitting end corresponding to one through hole 210 and the signal receiving end and the signal transmitting end corresponding to the adjacent through hole 210 is too close. In this way, multiple through holes 210 will be arranged close to the outer peripheral wall of the driving wheel 220.

[0078] In one embodiment, see Figure 4 and Figure 5 The first magnetic member 300 is arranged on the driven wheel 230, and the first sensor 400 is arranged on one side of the driven wheel 230; the signal transmitting end and the signal receiving end are respectively arranged on opposite sides of the driven wheel 230, and the multiple through holes 210 are arranged at intervals along the circumference of the driven wheel 230.

[0079] According to the above-mentioned embodiment, in this embodiment, the first magnetic member 300 is arranged on the driven wheel 230, the sensor is arranged on one side of the driven wheel 230, and the signal transmitting end and the signal receiving end are respectively arranged on opposite sides of the driven wheel 230. In this embodiment, the first sensor 400 and the second sensor 500 are used to measure the rotation speed information and time information of the driven wheel 230 respectively. The multiple through holes 210 opened on the driven wheel 230 are arranged at intervals along the circumference of the driving wheel 220. In this way, the signal emitted by the signal transmitting end can pass through all the through holes 210 and be received by the signal receiving end after the driving wheel 220 rotates one circle. The multiple through holes 210 are arranged at intervals, so that the signal reception has breakpoints, and the signal emitted continuously by the signal transmitting end can be divided into multiple signal information to be received by the signal receiving end, so that the time information of the signal transmitting end and the signal receiving end from a corresponding through hole 210 to another corresponding adjacent through hole 210 can be measured.

[0080] In one embodiment, see Figure 4 and Figure 5 , the plurality of through holes 210 are arranged at equal intervals along the circumference of the driven wheel 230. Considering that in order to accurately measure the instantaneous rotation speed of the driven wheel 230 and the accurate average speed of the driven wheel 230 within one rotation, the plurality of through holes 210 are arranged at equal intervals along the circumference of the driven wheel 230. In this way, when the rotation speed of the driven wheel 230 is stable, the time interval from one through hole 210 corresponding to the second sensor 500 to the adjacent through hole 210 corresponding to the second sensor 500 is equal.

[0081] In one embodiment, see Figure 4 and Figure 5 , a plurality of through holes 210 are arranged close to the outer peripheral wall of the driven wheel 230 .

[0082] Furthermore, considering that, when the driven wheel 230 rotates, there should be an obvious time interval between the signal receiving end and signal transmitting end corresponding to a through hole 210 and the signal receiving end and signal transmitting end corresponding to an adjacent through hole 210. If multiple through holes 210 are arranged at a position close to the axis of the driving wheel 220, the time interval between the signal receiving end and signal transmitting end corresponding to a through hole 210 and the signal receiving end and signal transmitting end corresponding to an adjacent through hole 210 is too close. In this way, multiple through holes 210 will be arranged close to the outer peripheral wall of the driven wheel 230.

[0083] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 5The flywheel assembly 200 also includes a transmission wheel 240 rotatably mounted on the frame 100. The transmission wheel 240 is coaxially arranged with the driven wheel 230, and the transmission wheel 240 and the driven wheel 230 rotate synchronously. The driving wheel 220 is transmission-connected with the transmission wheel 240. The transmission wheel 240 and the driving wheel 220 are arranged on the same side of the frame 100, and the driven wheel 230 and the driving wheel 220 are arranged on opposite sides of the frame 100.

[0084] It should be noted that, in the above embodiment, it has been described that the flywheel assembly 200 at least includes a driving wheel 220 and a driven wheel 230. In addition, the flywheel assembly 200 also includes a transmission wheel 240 rotatably mounted on the frame 100, that is, the transmission wheel 240 can rotate relative to the frame 100, wherein the driving wheel 220 and the transmission wheel 240 are transmission-connected, and the transmission wheel 240 is coaxially arranged with the driven wheel 230, and the transmission wheel 240 and the driven wheel 230 rotate synchronously, so that the driving wheel 220 can drive the driven wheel 230 to rotate.

[0085] It should be noted that the transmission wheel 240 and the driving wheel 220 are arranged on the same side of the frame 100 , while the driven wheel 230 and the driving wheel 220 are arranged on opposite sides of the frame 100 .

[0086] For further information, see Figure 1 , Figure 2 , Figure 4 and Figure 5 , the diameter of the transmission wheel 240 is smaller than the diameter of the driving wheel 220 and the diameter of the transmission wheel 240 is smaller than the diameter of the driven wheel 230 .

[0087] According to the above embodiment, the transmission wheel 240 and the driving wheel 220 are arranged on the same side of the frame 100, and the driven wheel 230 and the driving wheel 220 are arranged on opposite sides of the frame 100. Considering that the installation space on one side of the frame 100 is limited, if the driving wheel 220 and the driven wheel 230 are installed on the same side of the frame 100, the driving wheel 220 and the driven wheel 230 will rub and collide during the transmission process, and even due to insufficient space, the driving wheel 220 and the driven wheel 230 cannot be connected to each other. In view of this, a transmission wheel 240 with a diameter smaller than that of the driven wheel 230 is provided to directly connect the driving wheel 220 to the driven wheel 230, thereby realizing an indirect transmission connection between the driving wheel 220 and the driven wheel 230. It should be noted that the diameter of the transmission wheel 240 is also smaller than that of the driven wheel 230, and the transmission wheel 240 and the driving wheel 220 are arranged on the same side of the frame 100 and no friction or collision occurs during the transmission process.

[0088] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 5 The fitness equipment further includes a generator 600, and the driven wheel 230 is transmission-connected to the generator 600.

[0089] A generator 600 is also provided in the fitness equipment, which can drive the driven wheel 230 to rotate by continuously driving the driving wheel 220 to rotate, and then drive the generator 600 to rotate and cut the magnetic flux lines to generate electricity. The electricity generated is mainly used in the fitness bike to provide power for the resistance adjustment device, display device, and other electronic control devices in the fitness bike, thereby saving electricity costs.

[0090] In one embodiment, see Figures 1 to 5 The flywheel assembly 200 also includes a pedal assembly 250, which includes a crank 251 and a pedal 252. One end of the crank 251 is connected to the middle of the driving wheel 220, and the other end of the crank 251 is connected to the pedal 252. The pedal 252 rotates along the circumferential direction of the driving wheel 220 to drive the driving wheel 220 to rotate.

[0091] It should be noted that, further, when the fitness equipment is a spinning bike, the driving device of the flywheel assembly 200 is a pedal assembly 250, and the pedal assembly 250 includes a crank 251 and a pedal 252 connected to each other, and the crank 251 and the pedal 252 can be connected in rotation or fixedly connected. Specifically, in this embodiment, the crank 251 and the pedal 252 are connected in rotation through a rotating shaft. The crank 251 is fixedly connected to the driving wheel 220, and the user applies a driving force to the pedal 252 to drive the crank 251 to rotate, and the crank 251 drives the driving wheel 220 to rotate.

[0092] In one embodiment, see Fig. 9 and Fig.10 When the second sensor is set as a Hall sensor 400 , a plurality of the second magnetic members 800 are set on the driving wheel 220 , or a plurality of the second magnetic members 800 are set on the driven wheel 230 .

[0093] In the present embodiment, there are two ways of setting the second magnetic member 800. One is to set a plurality of second magnetic members 800 on the driving wheel 220, and then the second sensor is also set corresponding to the driving wheel 220; the other is to set a plurality of second magnetic members 800 on the driven wheel 230, and then the second sensor is also set corresponding to the driven wheel 230. Both of the above embodiments are within the protection scope of the present embodiment.

[0094] Specifically, see Fig. 9 and Fig.10The first magnetic member 300 is arranged on the driving wheel 220, and the plurality of second magnetic members 800 are distributed at intervals along the circumference of the driving wheel 220; the first sensor is arranged on one side of the driving wheel 220, and the second sensor and the first sensor are distributed at intervals along the circumference of the driving wheel 220.

[0095] The plurality of second magnetic members 800 are distributed along the circumference of the driving wheel 220 and are spaced apart from each other in the circumference of the driving wheel 220 . Such an arrangement can make the magnetic field signal measured by the second magnetic members 800 have a more obvious change.

[0096] In one embodiment, see Fig. 9 and Fig.10 The plurality of second magnetic members 800 are arranged at equal intervals along the circumference of the driven wheel 230 .

[0097] It should be noted that in order to measure the instantaneous speed of the driving wheel 220 more accurately and the accurate average speed of the driving wheel 220 within one rotation, a plurality of second magnetic parts 800 are arranged at equal intervals along the circumference of the driving wheel 220. In this way, when the rotation speed of the driving wheel 220 is stable, the time interval from a second magnetic part 800 corresponding to the second sensor to an adjacent second magnetic part 800 corresponding to the second sensor is equal.

[0098] In another embodiment, the first magnetic member 300 is disposed on the driven wheel 230, and the plurality of second magnetic members 800 are spaced apart along the circumference of the driven wheel 230; the first sensor is disposed on one side of the driven wheel 230, and the second sensor and the first sensor are spaced apart along the circumference of the driven wheel 230.

[0099] In one embodiment, the plurality of second magnetic members 800 are arranged at equal intervals along the circumference of the driven wheel 230 .

[0100] It should be noted that in order to measure the instantaneous speed of the driven wheel 230 more accurately and the accurate average speed of the driven wheel 230 within one rotation, a plurality of second magnetic parts 800 are arranged at equal intervals along the circumference of the driven wheel 230. In this way, when the rotation speed of the driven wheel 230 is stable, the time interval from a second magnetic part 800 corresponding to the second sensor to an adjacent second magnetic part 800 corresponding to the second sensor is equal.

[0101] In one embodiment, see Fig. 9 and Fig.10 , the number of the second magnetic members 800 is N, and N satisfies 2≤N≤12.

[0102] In this embodiment, the number of the second magnetic members 800 is set to 4. Considering that if the number of the second magnetic members 800 is too small, the instantaneous speed measured by the second sensor is not accurate enough. In view of this, it is not advisable to set the number of the second magnetic members 800 too small. Considering that the second magnetic members 800 have a certain size, the driven wheel 230 or the driving wheel 220 has a certain area, when the second magnetic members 800 are set too many, the second sensor cannot clearly distinguish the magnetic field signals of different second magnetic members 800. In view of this, it is not advisable to set the number of the second magnetic members 800 too many.

[0103] According to the above embodiment, in a preferred embodiment, please refer to Figure 3 The crank 251 forms a projection area toward the driving wheel 220 , and the first magnetic member 300 is disposed on the driving wheel 220 and located in the projection area.

[0104] Specifically, when the first magnetic member 300 is set on the projection area, the position of the first magnetic member 300 corresponds exactly to the position of the crank 251. When the crank 251 is perpendicular to the horizontal plane, the pedal 252 is at the highest point or the lowest point in the circumferential motion. At this time, the user's motion resistance is the largest during the circumferential motion of the pedal 252. According to the position information at this time, the resistance is reduced through the resistance adjustment module to make the user's motion easier. When the pedal 252 reaches the same distance from the highest point and the lowest point in the circumferential motion, the user's motion resistance is the smallest during the circumferential motion of the pedal 252. According to the position information at this time, the resistance is increased through the resistance adjustment device, so that the user's motion resistance is uniform, so that the user's motion experience is better.

[0105] In one embodiment, see Figures 1 to 6 , the number of the through holes 210 is M, and M satisfies 4≤M≤20.

[0106] Considering that if the number of through holes 210 is too small, the instantaneous speed measured by the second sensor 500 is not accurate enough. In view of this, it is not advisable to set the number of through holes 210 too small; considering that the through holes 210 have a certain size, the driven wheel 230 or the driving wheel 220 has a certain area, when too many through holes 210 are set, the receiving end of the second sensor 500 measures that the signals passing through the two through holes 210 are continuous into one signal, and the signals cannot be separated. In view of this, it is not advisable to set the number of through holes 210 too large.

[0107] Therefore, the number of through holes 210 should be set within a reasonable range. Experimental tests show that setting the number M of through holes 210 within 4≤M≤20 can meet the basic requirements of this solution.

[0108] In one embodiment, see Figures 1 to 6 , where M satisfies 8≤M≤12.

[0109] Furthermore, the number M of through holes 210 is limited to 8 to 12. Within this range, a better embodiment is to set the number of through holes 210 to 8, the number of through holes 210 to 10 and the number of through holes 210 to 12. Setting the number of through holes 210 within this range can not only ensure that the measured instantaneous speed is more accurate, but also ensure that the two signals measured to continuously pass through the through holes 210 will not become one signal received by the signal receiving end.

[0110] In one embodiment, see Figure 3 , Figure 6 and Figure 7 The fitness equipment further includes a mounting bracket 700 , wherein the mounting bracket 700 is connected to the frame 100 , and the first sensor 400 and the second sensor 500 are both mounted on the mounting bracket 700 .

[0111] The mounting bracket 700 is used to mount the first sensor 400 and the second sensor 500. The mounting bracket 700 is connected to the vehicle frame 100. The specific connection method can be welding, screw connection, or adhesive connection, which is not specifically limited here. In this embodiment, the mounting bracket 700 is set as one, and the installation is directly distributed on the opposite sides of the driving wheel 220 or the driven wheel 230. The first sensor 400 and the second sensor 500 are both arranged on the mounting bracket 700. Of course, not limited to the above embodiment, two mounting brackets 700 can also be provided, and one mounting bracket 700 can be installed with the first sensor 400, and the other mounting bracket 700 can be installed with the second sensor 500, or one mounting bracket 700 can be installed with the first sensor 400 and one of the signal transmitting end or the signal receiving end, and the other mounting bracket 700 can be installed with the other of the signal transmitting end and the signal receiving end. Of course, three mounting brackets 700 can also be provided, and the three mounting brackets 700 are used to install the first sensor 400, the signal receiving end, and the signal transmitting end, respectively, and the number of the mounting brackets 700 is not specifically limited here.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
