[0030] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings.

[0031] Bearing Z is an important component in mechanical equipment, and its main function is to support the rotation of the rotating shaft M.

[0032] In some embodiments, in order to realize the function of bearing Z to support the rotation of rotating shaft M, a housing is usually used to fix bearing Z. For example, the housing has a bearing Z hole for installing bearing Z, and bearing Z is located within the bearing Z hole so that the bearing Z hole and bearing Z are relatively fixed.

[0033] However, since the fixing effect of the housing on the bearing Z is poor, creep is likely to occur between the bearing Z and the housing, leading to abnormal operation of the bearing Z.

[0034] Figure 1 FIG. 4 is a schematic structural view of a stopping device 100 provided by an embodiment of the present application. Refer to Figure 1 , the stopping device 100 includes: a fixing member 101, a member to be stopped 102, and a stopping assembly 103.

[0035] Among them, refer to Figure 2 , the fixing member 101 has a receiving space 101a and a stopping hole 101b. The member to be stopped 102 is located in the receiving space 101a, and the member to be stopped 102 and the fixing member 101 are in contact with the side wall of the receiving space 101a. One side of the member to be stopped 102 close to the fixing member 101 has a stopping groove 102a. The stopping groove 102a and the stopping hole 101b are arranged opposite to each other.

[0036] Optionally, the relative arrangement of the stopping groove 102a and the stopping hole 101b may mean that the positions of the stopping groove 102a and the stopping hole 101b are relative, and the stopping groove 102a can be seen when viewed from the side of the stopping hole 101b away from the stopping groove 102a. That is, the stopping hole 101b can expose the stopping groove 102a.

[0037] Refer to Figure 1 , the stopping assembly 103 includes: a stopping portion 1031. The stopping portion 1031 can be located in the stopping groove 102a and the stopping hole 101b, that is, a part of the stopping portion 1031 is located in the stopping groove 102a, and the other part is located in the stopping hole 101b. In order for the stopping assembly 103 to stop the member to be stopped 102, it is necessary to make a part of the stopping portion 1031 located in the stopping groove 102a abut against the member to be stopped 102. In addition, in order for the other part of the stopping portion 1031 to be located in the stopping hole 101b when the stopping portion 1031 abuts against the member to be stopped 102, the length of the stopping portion 1031 along the length direction of the stopping hole 101b can be greater than the depth of the stopping groove 102a.

[0038] In addition, the stopping assembly 103 further includes: an elastic member 1032 and a limiting member 1033. One end of the elastic member 1032 abuts against the stopping portion 1031, and the other end abuts against the limiting member 1033. The limiting member 1033 is fixedly connected to the fixing member 101.

[0039] Among them, the fixed connection between the limiting member 1033 and the fixing member 101 can include two cases: 1. The limiting member 1033 is located in the stopping hole 101b and is fixedly connected to the side wall of the stopping hole 101b in the fixing member 101; 2. The limiting member 1033 is located outside the stopping hole 101b and is fixedly connected to the side of the fixing member 101 away from the member to be stopped 102.

[0040] Since one end of the elastic member 1032 abuts against the stopping portion 1031 and the other end abuts against the limiting member 1033, the elastic member 1032 can be limited between the stopping portion 1031 and the limiting member 1033. By adjusting the elastic force of the elastic member 1032, the abutting force of the elastic member 1032 against the stopping portion 1031 can be adjusted, and further the stopping force of the stopping portion 1031 against the member to be stopped 102 can be adjusted. Thus, the stopping assembly 103 can play a better stopping role on the member to be stopped 102, and further reduce the relative movement between the member to be stopped 102 and the fixing member 101.

[0041] In summary, the embodiment of the present application provides a stopping device, which includes a fixing member, a member to be stopped, and a stopping assembly. By providing a stopping hole on the fixing member, a stopping groove on the member to be stopped, and arranging the stopping portion of the stopping assembly in the stopping groove and the stopping hole, and through the limiting action of the limiting member of the stopping assembly, the stopping portion abuts against the member to be stopped under the action of the elastic force of the elastic member of the stopping assembly, so as to realize the stopping of the member to be stopped and avoid the relative movement of the member to be stopped in the accommodating space of the fixing member. That is, the embodiment of the present application has high flexibility in preventing the relative movement between the member to be stopped and the fixing member by specially designing the fixing member and the member to be stopped and adopting the stopping assembly.

[0042] In the embodiment of the present application, the number of the stopping holes 101b provided on the fixing member 101 can be the same as the number of the stopping grooves 102a provided on the member to be stopped 102, and they are in one-to-one correspondence. For example, one stopping hole 101b is provided on the fixing member 101, and correspondingly, another stopping groove 102a is provided on the member to be stopped 102. Of course, the number of the stopping holes 101b provided on the fixing member 101 and the number of the stopping grooves 102a provided on the member to be stopped 102 can also be multiple, and the embodiment of the present application does not limit this.

[0043] Further, the number of the stopping portions 1031, the elastic members 1032, and the limiting members 1033 included in the stopping assembly 103 can also be the same as the number of the stopping holes 101b provided on the fixing member 101, and they are in one-to-one correspondence. Thus, the stopping portions 1031 included in the stopping assembly 103 can be located in the corresponding stopping grooves 102a and stopping holes 101b, so that the elastic members 1032 can abut against the corresponding stopping portions 1031, and the limiting members 1033 can be used to limit the corresponding elastic members 1032.

[0044] In the embodiment of the present application, when the stopping device 100 is applied to stop a bearing Z as shown in Figure 3 the member to be stopped 102 can be the outer ring of the bearing Z, and the fixing member 101 can be a housing for fixing the bearing Z. Among them, refer to Figure 3The bearing Z includes a bearing outer ring Z1, a bearing inner ring Z2, and a rolling element Z3 located between the bearing outer ring Z1 and the bearing inner ring Z2.

[0045] Optionally, the rolling element Z3 may be a ball, a cylindrical roller, a tapered roller, a needle roller, etc. For example, the bearing Z may be a ball bearing, a cylindrical roller bearing, a tapered roller bearing, a needle roller bearing, etc. The embodiment of the present application does not limit the type of the bearing Z.

[0046] When the bearing Z is installed and used, the inner ring Z2 of the bearing can be fitted with an interference fit between the rotating shaft M, while the outer ring Z1 of the bearing can be fitted with a transition fit or a clearance fit between the fixing member 101 (housing). In this case, if the bearing Z is used in a low-speed operation scenario, the transition fit or clearance fit between the outer ring Z1 of the bearing and the housing will have little impact on the operation of the bearing Z. However, if the bearing Z is used in a high-speed operation scenario, the outer ring Z1 of the bearing can creep with the housing, causing abnormal operation of the bearing Z, severe vibration of the entire machine, and in severe cases, shutdown. In other words, although the bearing Z can be used in scenarios such as high speed, high torque, and reverse rotation, its operating environment is extremely harsh. Therefore, to ensure the operation of the bearing Z in various scenarios, the stop device 100 provided in the embodiment of the present application can be used to stop the outer ring Z1 of the bearing Z.

[0047] For example, when the stop device 100 is used to stop the outer ring Z1 of a bearing Z, a stop hole 101b can be provided on the fixing member 101 (housing), and a stop groove 102a can be provided on the outer ring Z1 of the bearing Z. A stop portion 1031 in the stop assembly 103 is located within the stop groove 102a of the outer ring Z1 and within the stop hole 101b of the housing. The elastic member 1032 in the stop assembly 103, restrained by the stop member 1033, abuts against the stop portion 1031, ensuring that the stop portion 1031 abuts against the outer ring Z1. This prevents relative movement between the housing and the outer ring Z1, and prevents creep between the outer ring Z1 and the housing during rotation, thereby preventing abnormal operation of the bearing Z.

[0048] Alternatively, bearings can be used in a wide variety of applications, such as in vehicle drive systems, rear wheels, transmissions, and electrical components, as well as in motors, household appliances, instruments and meters, internal combustion engines, railway vehicles, construction machinery, agricultural machinery, and loading and handling machinery. In the embodiments of the present application, if a bearing in a variety of industrial machinery needs to be stopped, the stopping device 100 of the embodiments of the present application can be used to achieve this.

[0049] Of course, it should be noted that the stopping device 100 can also be applied to stop other types of components, and the embodiments of the present application do not limit this. For example, to prevent the shaft from rotating relative to the sleeve, a stopping hole can be provided on the sleeve and a stopping groove can be provided on the shaft. The stopping part in the stopping assembly is located in the stopping groove of the shaft and the stopping hole of the sleeve, and the elastic part in the stopping assembly abuts against the stopping part under the limitation of the limiting part, so that the stopping part abuts against the shaft, thereby realizing the stopping of the shaft.

[0050] In the embodiments of the present application, referring to Figure 4 , the first part 10311 of the stopping part 1031 is located in the stopping groove 102a, and the second part 10312 is located in the stopping hole 101b. By arranging the first part 10311 of the stopping part 1031 in the stopping groove 102a of the component to be stopped 102 and the second part 10312 in the stopping hole 101b of the component to be stopped 102, it can be avoided that the elastic part 1032 crosses the interface between the component to be stopped 102 and the fixing part 101, ensuring the reliable abutment of the elastic part 1032 against the stopping part 1031, and further ensuring that the stopping part 1031 is stably and reliably arranged between the elastic part 1032 and the component to be stopped 102, and ensuring the stopping effect of the stopping part 1031 on the component to be stopped 102.

[0051] Among them, the ratio range of the length of the second part 10312 to the length of the first part 10311 is from 2:3 to 3:2, that is, the length of the second part 10312 and the length of the first part 10311 can be approximately equal. For example, the ratio of the length of the second part 10312 to the length of the first part 10311 is 1:1. That is to say, the length of the second part 10312 can be equal to the length of the first part 10311.

[0052] Among them, the lengths of both the first part 10311 and the second part 10312 are the lengths along the extending direction of the stopping hole 101b. The extending direction of the stopping hole 101b is perpendicular to the surface of the fixing part 101 where the stopping hole 101b is provided.

[0053] Optionally, the total length of the stopping part 1031 along the extending direction X of the stopping hole 101b can be equal to the sum of the length of the second part 10312 and the length of the first part 10311. That is to say, the fixing part 101 and the component to be stopped 102 are in contact setting (that is, there is no gap between the fixing part 101 and the component to be stopped 102), avoiding the stopping ball being located in the gap between the fixing part 101 and the component to be stopped 102, ensuring the reliability of the stopping part 1031 arranged in the stopping groove 102a and the stopping hole 101b, and further ensuring the abutting effect of the stopping part 1031 on the component to be stopped 102.

[0054] For example, assuming that the total length of the stop portion 1031 is 5 mm (millimeter), the ratio of the length of the second portion 10312 to the length of the first portion 10311 is 3:2, then the length of the second portion 10312 can be 3 mm, and the length of the second portion 10312 can be 2 mm.

[0055] In the embodiment of the present application, by making the length of the first part 10311 of the stop portion 1031 arranged in the stop groove 102a and the length of the second part 10312 arranged in the stop hole 101b approximately equal, it is possible to avoid the situation where the length of one of the first part 10311 of the stop portion 1031 located in the stop groove 102a and the second part 10312 of the stop portion 1031 located in the stop hole 101b is smaller, thereby affecting the stopping effect of the stop portion 1031 on the stop member 102.

[0056] Alternatively, the stopper 1031 may be spherical, for example, a stopper ball or a stopper steel ball. If the stopper 1031 is a stopper ball, the diameter of the stopper 1031 is the total length of the stopper 1031 along the extension direction of the stopper hole 101b. The diameter of the stopper ball may be the sum of the lengths of the first portion 10311 and the second portion 10312.

[0057] In the embodiment of the present application, the elastic member 1032 may be a spring. The spring, as an elastic member 1032, has a free state, a stretched state, and a compressed state. The free state of the spring refers to the state of the spring when no external force is applied. Typically, the free state of the spring is measured by the original length of the spring when it is not stretched or compressed. The stretched state and compressed state of the spring are both the states of the spring when an external force is applied. Typically, the length of the spring in the stretched state is greater than the original length of the spring in the free state, and the length of the spring in the compressed state is less than the original length of the spring in the free state.

[0058] When a spring is free, there is no stress or strain inside it, and no potential energy is stored. When an external force acts on a spring, it deforms—that is, it stretches or compresses. This deformation causes stress and strain inside the spring, which in turn stores potential energy.

[0059] To enable the spring to abut between the stop portion 1031 and the limiting member 1033, the spring disposed between the limiting member 1033 and the stop portion 1031 can be in a compressed state. That is, the distance between the limiting member 1033 and the stop portion 1031 can be less than the original length of the spring in its free state. In this case, the potential energy inside the spring causes the spring to have a tendency to return to its free state, that is, the elastic force of the spring will point in the opposite direction to the direction in which the spring is compressed, in an attempt to restore the original length of the spring. In this way, the spring will abut between the stop portion 1031 and the limiting member 1033, and apply an elastic force F in the direction towards the stop portion 1031 to the stop portion 1031, thereby causing the stop portion 1031 to apply an abutting force to the member to be stopped 102, ensuring the stopping effect on the member to be stopped 102.

[0060] When the elastic member 1032 is a spring, the elastic force of the spring can be adjusted by adjusting the original length of the spring in its free state. For example, the longer the original length of the spring in its free state, the greater the elastic force of the spring when it is confined between the stop portion 1031 and the limiting member 1033; the shorter the original length of the spring in its free state, the smaller the elastic force of the spring when it is confined between the stop portion 1031 and the limiting member 1033.

[0061] In addition, the elastic force of the spring can also be adjusted by adjusting the number of turns of the spring, the shape or area of the cross-section of the spring. The embodiments of the present application do not limit this, as long as the elastic force of the spring can ensure the stopping effect on the member to be stopped 102 when the spring is confined between the stop portion 1031 and the limiting member 1033.

[0062] Reference Figure 1 and Figure 4 It can be seen that the limiting member 1033 can be located on the side of the fixing member 101 away from the member to be stopped 102. The orthographic projection of the limiting member 1033 on the fixing member 101 covers the stop hole 101b, and the area of the orthographic projection of the limiting member 1033 on the fixing member 101 is larger than the cross-sectional area of the stop hole 101b. In this case, the limiting member 1033 can be a plate-shaped member. For example, the limiting member 1033 can also be referred to as a pressing plate. The stop hole 101b can be a stop through hole penetrating the fixing member 101.

[0063] Among them, the cross-sectional area of the stop hole 101b is the projected area of the stop hole 101b on the reference plane, and the reference plane is parallel to the surface of the fixing member 101 for setting the stop hole 101b. That is, the limiting member 1033 has a portion that extends beyond the stop hole 101b.

[0064] Optionally, the cross-sectional shape of the stop hole 101b can be circular or polygonal. Among them, the polygon can include regular polygons and non-regular polygons. For example, the polygon can include rectangles, squares, and regular hexagons, etc.

[0065] Exemplarily, when the stop portion 1031 is a stop ball, the cross-sectional shape of the stop hole 101b can be circular. The diameter range of the stop hole 101b is 6 mm to 10 mm. The reason for selecting the diameter range of the stop hole 101b is as follows: If the diameter of the stop hole 101b is less than 6 mm, the requirement for machining accuracy is higher and the machining is more complex; if the diameter of the stop hole 101b is greater than 10 mm, the fixing member 101 will be affected by the too large size of the stop hole 101b and its strength will be affected.

[0066] Reference Figure 4 , the limiting member 1033 has a connecting through hole 1033a, and the orthographic projection of the connecting through hole 1033a on the housing does not overlap with the stop hole 101b. Reference Figure 2 , the side of the fixing member 101 away from the member to be stopped 102 has a connecting hole 101c. The stop assembly 103 further includes: a connecting member 1034. The connecting member 1034 passes through the connecting through hole 1033a and is connected to the connecting hole 101c, so that the limiting member 1033 and the fixing member 101 are fixedly connected through the connecting member 1034.

[0067] Exemplarily, the connecting through hole 1033a can be a light hole, the connecting hole 101c can be a threaded hole, and the connecting member 1034 can be a bolt. Thus, after the bolt passes through the connecting through hole 1033a, it is connected to the connecting hole 101c by means of threaded connection. That is to say, the bolt can be used as a connecting member for connecting the limiting member 1033 and the fixing member 1031, and the bolt can also be called a fixing bolt.

[0068] Optionally, the bolt includes a head and a screw rod (the screw rod is a cylinder with external threads) that are connected to each other. The orthographic projection of the screw rod on the head is located inside the head, and the area of the orthographic projection of the screw rod on the head is smaller than the cross-sectional area of the head. The cross-sectional area of the head can be represented by the area of the projection of the head on the surface perpendicular to the extending direction of the screw rod.

[0069] Reference Figure 5, the connecting through hole 1033a may include a first hole portion 1033a1 and a second hole portion 1033a2. The first hole portion 1033a1 is farther from the fixing member 101 than the second hole portion 1033a2, and the width of the first hole portion 1033a1 is greater than the width of the second hole portion 1033a2. The width of the head of the bolt may be greater than the width w2 of the second hole portion 1033a2 and less than the width w1 of the first hole portion 1033a1, and the diameter of the screw of the bolt is less than the width w2 of the second hole portion 1033a2. Thus, the head of the bolt can be located within the first hole portion 1033a1, and the screw passes through the second hole portion 1033a2 and is connected to the connection hole 101c.

[0070] Exemplarily, the height h1 of the first hole portion 1033a1 may be greater than the height of the head of the bolt, so as to avoid the surface of the head of the bolt being higher than the surface of the fixing member 101 and ensure the flatness of the surface of the fixing member 101. The height h2 of the second hole portion 1033a2 is less than the length of the screw of the bolt, so as to ensure that the screw can be connected to the connection hole 101c.

[0071] Wherein, the width w1 of the first hole portion 1033a1, the width w2 of the second hole portion 1033a2, and the width of the head are all lengths in the direction Y (the direction Y is perpendicular to the direction X). The height of the first hole portion 1033a1 and the height of the head of the bolt are both lengths in the direction X.

[0072] In the embodiment of the present application, the stop assembly 103 may include a plurality of connecting members 1034. The orthographic projections of the plurality of connecting members 1034 on the fixing member 101 are uniformly arranged around the stop hole 101b. By providing a plurality of connecting members 1034 in the stop assembly 103, the reliability of the fixed connection between the limiting member 1033 and the fixing member 101 can be ensured, and the effective abutment of the limiting member 1033 against the elastic member 1032 can be ensured.

[0073] Exemplarily, the stop assembly 103 may include 3 connecting members 1034, and the orthographic projections of the 3 connecting members 1034 on the fixing member 101 are uniformly arranged around the stop hole 101b.

[0074] In the embodiment of the present application, the fixing member 101 includes a first fixing portion 1011 and a second fixing portion 1012. The first fixing portion 1011 is an annular portion. The annular portion has a first opening 1011a and a second opening 1011b. The second fixing portion 1012 is located on the side of the first opening 1011a away from the second opening 1011b, and the edge of the second fixing portion 1012 is connected to the boundary of the first opening 1011a, so that the first fixing portion 1011 and the second fixing portion 1012 form an accommodation space 101a. Exemplarily, the first fixing portion 1011 and the second fixing portion 1012 may form a barrel-shaped structure.

[0075] Wherein, the stopping hole 101b is located on the first fixing portion 1011, and the stopping groove 102a is located on the side of the member to be stopped 102 close to the first fixing portion 1011.

[0076] When the member to be stopped 102 is a bearing Z, the elastic member 1032 (such as a spring) disposed in the stopping hole 101b of the fixing member 101 (housing) pushes the stopping portion 1031 to abut against the stopping groove 102a on the outer ring Z1 of the bearing Z in the bearing Z, so as to cause a creeping phenomenon between the outer ring Z1 of the bearing and the fixing member 101 (housing). After the bearing Z is installed in the accommodation space 101a of the fixing member 101 (housing), during high-speed operation, the stopping portion 1031 in the stopping assembly 103 abuts in the stopping groove 102a on the outer ring Z1 of the bearing, thereby preventing the circumferential movement of the outer ring Z1 of the bearing and ensuring the normal operation of the bearing Z. Thus, the vibration of the machine body caused by abnormal operation of the bearing Z can be prevented, and the stability of the movement of the bearing Z (i.e., high stability) can be improved.

[0077] Moreover, the scheme of the embodiment of the present application in the installation process includes: machining the stopping hole 101b on the fixing member 101; machining the stopping groove 102a on the member to be stopped 102; installing the member to be stopped 102 in the accommodation space 101a of the fixing member 101; putting the stopping portion 1031 and the elastic member 1032 into the stopping hole 101b; rotating the member to be stopped 102 so that the stopping portion 1031 falls into the stopping groove 102a of the member to be stopped 102; blocking the stopping hole 101b with the limiting member 1033; connecting the limiting member 1033 and the fixing member 101 with the connecting member 1034. The scheme of the embodiment of the present application is not only simple in structure, but also easy to install and has good use performance.

[0078] That is, if the solution of the embodiment of the present application needs to achieve the stopping of the bearing Z, only a stopping hole 101b needs to be provided on the fixing member 101 (housing), and a stopping groove 102a needs to be provided on the member to be stopped 102 (bearing outer ring Z1). And, the stopping portion 1031 in the stopping assembly 103 is arranged in the stopping groove 102a and the stopping hole 101b, and the elastic member 1032 is arranged in the stopping hole 101b. Finally, the elastic member 1032 is limited by the limiting member 1033, so that the elastic member 1032 has a certain elastic force between the limiting member 1033 and the stopping portion 1031, and further enables the stopping portion 1031 to apply a pressing force to the bearing Z under the action of the elastic force, thereby achieving the stopping of the bearing Z.

[0079] In summary, the embodiment of the present application provides a stopping device, which includes a fixing member, a member to be stopped, and a stopping assembly. By providing a stopping hole on the fixing member, a stopping groove on the member to be stopped, arranging the stopping portion of the stopping assembly in the stopping groove and the stopping hole, and through the limiting action of the limiting member of the stopping assembly, the stopping portion abuts against the member to be stopped under the action of the elastic force of the elastic member of the stopping assembly, so as to achieve the stopping of the member to be stopped and avoid the relative movement of the member to be stopped in the accommodating space of the fixing member. That is, the embodiment of the present application has high flexibility in preventing the relative movement of the member to be stopped and the fixing member by specially designing the fixing member and the member to be stopped and adopting a stopping assembly.

[0080] The embodiment of the present application also provides a vehicle, which may include a vehicle body and a stopping device 100 as provided in the above embodiment located inside the vehicle body.

[0081] Optionally, the vehicle may be a new energy vehicle, a hybrid vehicle, or a pure electric vehicle. The vehicle may include a drive system, the drive system may include bearings, and the bearings in the drive system may be stopped by using the stopping device 100. For example, the bearing outer ring of the bearing in the drive system may be the member to be stopped 102 in the stopping device 100.

[0082] Since the vehicle can have substantially the same technical effects as the stopping device described in the previous embodiment, for the sake of brevity, the technical effects of the vehicle are not described herein again.
