[0003] During the vehicle detection process, the vehicle needs to be fixed. Currently, it is usually done manually by placing sleepers in front of and behind the wheels, so as to lock the wheels through the sleepers to achieve the effect of fixing the vehicle.

Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0055] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the present application.

[0056] In addition, if terms such as "first" and "second" appear, these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0057] In the present application, unless otherwise clearly specified and limited, if terms such as "mounted", "connected", "connected to", "fixed", etc. appear, these terms should be understood in a broad sense.

The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0060] Referring to Figure 1 and Figure 2 , a fixing device provided in an embodiment of the present application includes a jacking platform 100 and a fixing structure 200 disposed on the jacking platform 100. A vehicle can enter into the jacking platform 100, and the vehicle can be jacked up by the jacking platform 100 to perform maintenance or testing on the chassis of the vehicle.

[0061] In order to keep the vehicle in a fixed position during the jacking process and prevent the vehicle from slipping off the jacking platform 100 during the jacking process, it is necessary to fix the vehicle through the fixing structure 200. To this end, the fixing structure 200 includes a fixing seat 210, two limiting units 250 and two blocking units 230. The fixing seat 210 is installed on the jacking platform 100 and has a fixing position 201 for accommodating the wheels of the vehicle; the two limiting units 250 are disposed on the fixing seat 210 and are respectively located on both sides of the fixing position 201 in the first direction X, and the two blocking units 230 are disposed on the fixing seat 210 and are respectively located on both sides of the fixing position 201 in the second direction Y.

[0062] After the vehicle enters the jacking platform 100 and continues to control the vehicle to move so that the wheels of the vehicle are located on the fixing position 201 on the fixing seat 210, the two limiting units 250 can be controlled to abut against or separate from both sides of the wheels in the first direction X, and the two blocking units 230 can be controlled to abut against or separate from both sides of the wheels in the second direction Y. That is to say, each limiting unit 250 can abut against one side of the wheel in the first direction X, and each blocking unit 230 can abut against one side of the wheel in the second direction Y.

[0063] Wherein, the first direction X is the rolling direction of the wheels located at the fixing position 201, and the second direction Y is the direction where the axes of the wheels located at the fixing position 201 are located. After the wheels of the vehicle are located on the fixing position 201, it is possible to control the two limiting units 250 to abut against both sides of the wheels in the first direction X, so that the rolling of the wheels in the first direction X is limited by the two limiting units 250, and then the two blocking units 230 abut against both sides of the wheels in the second direction Y, so that the swinging or moving of the wheels in the second direction Y is limited by the two blocking units 230.

[0064] In this way, the rolling of the wheel can be limited by the two limiting units 250, and the swinging and moving of the wheel can be limited by the two blocking units 230. The combination of the two limiting units 250 and the two blocking units 230 can fix and clamp the periphery of the wheel, so that the wheel can be fixed at the fixed position 201, thereby fixing the position of the vehicle and ensuring that the vehicle is always in a fixed position during the jacking and maintenance processes. Compared with the traditional method of placing sleepers in front of and behind the wheels, the above fixing device can fix the periphery of the wheel, with a better fixing effect, enabling the vehicle to always be in a fixed position during the test process, and effectively ensuring the normal progress of the vehicle detection process.

[0065] In some embodiments of the present application, referring to Figure 2 and Figure 3 , each blocking unit 230 includes a fixing member 231 and a blocking member 232. The fixing member 231 is installed on the fixing seat 210, and the blocking member 232 is installed on the side of the fixing member 231 facing the fixed position 201 and can move relative to the corresponding fixing member 231 along the first direction X. Herein, the fixing member 231 corresponding to the blocking member 232 refers to the fixing member 231 that belongs to the same blocking unit 230 as this blocking member 232.

[0066] In this way, when it is necessary to use the blocking unit 230 to abut against both sides of the tire in the second direction Y, the blocking members 232 of the two blocking units 230 can be controlled to move in the second direction Y until the two blocking members 232 respectively abut against both sides of the tire in the second direction Y, thereby completing the fixation of both sides of the tire in the second direction Y. If it is necessary to separate the blocking unit 230 from the tire, the two blocking members 232 can be moved in the reverse direction so that the two blocking members 232 are separated from the tire.

[0067] In some embodiments, in order to improve the blocking effect of the blocking member 232 on the tire, during the movement of each blocking member 232 relative to the fixing member 231, there are multiple fixed positions, and the blocking member 232 can be selectively fixed to the corresponding fixing member 231 at each fixed position. In this way, when the blocking member 232 moves to one of the fixed positions, if the blocking member 232 at this fixed position can abut against one side of the tire, the blocking member 232 can be fixed to the corresponding fixing member 231, thereby fixing the blocking member 232 at the current position and preventing the blocking member 232 from moving by itself when blocking the tire, which may affect the fixing effect of the tire.

[0068] In some specific embodiments, each blocking unit 230 further includes a movable sleeve 233. Each blocking unit 230 further includes a movable sleeve 233 connected to a corresponding blocking member 232. A plurality of limiting members 234 are arranged at intervals along the second direction Y on the outer peripheral surface of the movable sleeve 233, and each limiting member 234 is extendable or retractable relative to the movable sleeve 233. Wherein, the blocking member 232 correspondingly connected to the movable sleeve 233 refers to the blocking member 232 in the same blocking unit 230 as the movable sleeve 233.

[0069] Wherein, when all the limiting members 234 are retracted, the movable sleeve 233 can move relative to the fixing member 231 along the second direction Y, so as to drive the limiting members 234 to move in the second direction Y through the movable sleeve 233, so that the limiting members 234 can abut against or separate from the tire.

[0070] When any one of the limiting members 234 extends, the fixing member 231 is located on the path of the extended limiting member 234 moving with the movable sleeve 233. By abutting the fixing member 231 against the limiting member 234, the fixing member 231 prevents the limiting member 234 from continuing to move, thereby preventing the movable sleeve 233 from continuing to move. Thus, when the movable sleeve 233 drives the blocking member 232 to move until the blocking member 232 abuts against the tire, the two limiting members 234 closest to the fixing member 231 are extended, so that the fixing member 231 is located between the two extended limiting members 234. At this time, whether the movable sleeve 233 moves forward or backward in the second direction Y, the fixing member 231 will abut against one of the limiting members 234, making the movable sleeve 233 unable to continue moving in the second direction Y, thereby fixing the movable sleeve 233 at this position, and further making the limiting members 234 always in a state of abutting against the tire.

[0071] Specifically in Figure 2 In the embodiments, an adjustment hole 218 is provided through the fixing member 231 along the first direction X. The movable sleeve 233 is inserted into the adjustment hole 218 and connected to the corresponding blocking member 232. When all the limiting members 234 are retracted, the movable sleeve 233 can move in the adjustment hole 218. When the limiting members 234 extend, the limiting members 234 cannot pass through the adjustment hole 218, thereby preventing the movable sleeve 233 from continuing to move by the abutment of the limiting members 234 against the fixing member 231.

[0072] Further, a plurality of limiting members 234 are arranged at intervals around the circumference of the movable sleeve 233 as a group, and multiple groups of limiting members 234 are arranged at intervals along the second direction Y. When it is necessary to fix the movable sleeve 233, the two groups of limiting members 234 closest to the adjustment hole 218 can be all extended, so as to abut against the fixing member 231 simultaneously through the multiple limiting members 234 in each group, thereby improving the fixing effect on the movable sleeve 233.

[0073] In some specific embodiments, in order to enable the limiting member 234 to extend and retract from the movable sleeve 233, the movable sleeve 233 includes a sealed piston chamber 235, and the pressure in the piston chamber 235 can be controllably increased or decreased. The movable sleeve 233 further includes a plurality of expansion members 236 disposed in the piston chamber 235, and a plurality of expansion holes 237 are provided on the outer peripheral surface of the movable sleeve 233. Each expansion hole 237 communicates with the interior of one of the expansion members 236, and each limiting member 234 passes through one of the expansion holes 237;

[0074] When the pressure in the piston chamber 235 increases, the volume of the expansion member 236 decreases, and there is not enough space inside the expansion member 236 to accommodate the limiting member 234. At this time, during the shrinking process of the expansion member 236, it can drive the limiting member 234 to extend out of the expansion hole 237, that is, the limiting member 234 extends relative to the movable sleeve 233, so that the movement of the movable sleeve 233 can be blocked by the extended limiting member 234.

[0075] When the pressure in the piston chamber 235 decreases, the volume of the expansion member 236 increases, and enough space is formed inside the expansion member 236 to accommodate the limiting portion. Under the action of its own gravity or the pressure applied by the user, the limiting member 234 can retract into the interior of the expansion member 236 through the expansion hole 237, so that the limiting member 234 can retract into the interior of the movable sleeve 233 and no longer block the movement of the movable sleeve 233.

[0076] Specifically to Figure 3 In the embodiments, in order to increase and decrease the pressure in the piston chamber 235, the movable sleeve 233 includes a cylinder body 238. A piston chamber 235 is provided inside the cylinder body 238, and expansion holes 237 are provided on the outer peripheral surface of the cylinder body 238. The movable sleeve 233 further includes a piston 239, which is movably installed on the cylinder body 238 and can compress and expand the piston chamber 235 during the movement. Thus, when the operator moves the piston 239 to compress the piston chamber 235, the pressure in the piston chamber 235 will increase. When the operator moves the piston 239 to expand the piston chamber 235, the pressure in the piston chamber 235 will decrease.

[0077] Specifically, a piston chamber 235 extending longitudinally in the second direction Y is provided inside the cylinder body 238. The piston 239 is movably installed inside the cylinder body 238 along the second direction Y, and the outer peripheral wall of the piston 239 is in close contact with the inner wall of the piston chamber 235, so that during the movement of the piston 239 in the second direction Y, the piston chamber 235 can be compressed and expanded. Among them, in order to facilitate the operator to operate the piston 239, the movable sleeve 233 further includes an operating rod 240. One end of the operating rod 240 is connected to the piston 239, and the other end extends out of the piston chamber 235. The operator can operate the end of the operating rod 240 extending out of the piston chamber 235 to control the movement of the piston 239 inside the piston chamber 235.

[0078] It should be noted that in other embodiments, the pressure inside the piston chamber 235 can also be increased and decreased by inflating or sucking air into the piston chamber 235 through an air pump.

[0079] In some embodiments of the present application, referring to Figure 4 and Figure 5 , in order to enable the limiting component to abut and limit both sides of the wheel in the first direction X, each limiting unit 250 includes a plug-in member 251 and a clamping plate member 252. The plug-in member 251 is installed on the fixed seat 210, and the clamping plate member 252 is installed on the side of the plug-in member 251 facing the fixed position 201. Both ends of the clamping plate member 252 in the longitudinal direction are connected to the plug-in member 251, and the middle part of the clamping plate member 252 is bent towards the fixed position 201.

[0080] When the wheel is located on the fixed position 201, the middle part of the clamping plate member 252 can abut against the wheel and deform towards the plug-in member 251 under the action of the wheel. Since the first direction X is the rolling direction of the wheel, the side surface of the wheel in the first direction X is a curved surface. After the clamping plate member 252 is deformed by the extrusion of the wheel, the clamping plate member 252 can fit with the side surface of the wheel, so that the effect of the clamping plate member 252 restricting the rolling of the wheel is better.

[0081] In some embodiments, at least one of the plug-in members 251 in the two limiting units 250 is detachably installed on the fixed seat 210. Since the limiting component is on the rolling path of the wheel, in order to enable the wheel to drive into the fixed position 201, before the wheel enters the fixed position 201, the plug-in member 251 on the driving path of the wheel can be removed from the fixed seat 210 to avoid the wheel. After the wheel enters the fixed position 201, the plug-in member 251 can be inserted into the fixed seat 210 again to fix the wheel through the clamping plate member 252 installed on the plug-in member 251.

[0082] Specifically in some embodiments, a plug hole 217 is provided on the fixing base 210, and the connector 251 can be inserted into the plug hole 217 to fix the connector 251 on the fixing base 210. When the connector 251 needs to be detached from the fixing base 210, the connector 251 only needs to be pulled out from the plug hole 217.

[0083] Specifically, in some embodiments, in order to improve the clamping effect of the clamping plate 252 on the wheel, the limiting unit 250 further includes an elastic member 253, one end of which is connected to the plug-in member 251, and the other end is connected to the middle of the clamping plate 252. In this way, the plug-in member 251 and the clamping plate 252 are elastically connected by the elastic member 253, and when the middle of the clamping plate 252 is squeezed and deformed by the wheel, the clamping plate 252 will also compress the spring, so that the spring is in a compressed state, and the spring in the compressed state will in turn compress the clamping plate 252, so that the clamping plate 252 can be closely attached to the wheel.

[0084] Optionally, the elastic member 253 is a spring, and in other embodiments, the elastic member 253 may also be a rubber band, or a rubber member or other elastic object.

[0085] Specifically in some embodiments, when the wheel drives into the fixed position 201 and then the connector 251 is inserted into the fixing seat 210, the connector 251 cannot be smoothly inserted into the fixing seat 210 due to the interference between the bent splint 252 and the wheel. The limiting unit 250 also includes a guide rod 254, which is slidably mounted on the connector 251 along the second direction Y, and one end of the guide rod 254 in the second direction Y is connected to the middle of the splint 252.

[0086] When the connector 251 needs to be inserted into the fixing seat 210, the guide rod 254 can be moved first, and the guide rod 254 then drives the middle part of the clamping plate 252 to retract toward the connector 251, reducing the interference between the clamping plate 252 and the wheel, so that the connector 251 can be smoothly inserted into the fixing seat 210. After the connector 251 is inserted, the guide rod 254 is released, and the clamping plate 252 will extend toward the wheel under the elastic force of itself and the elastic force of the elastic member 253, and finally fit with the wheel.

[0087] After the vehicle enters the lifting platform 100, it is also necessary to drive the wheels of the vehicle into the fixed position 201. However, since the fixing seat 210 has a certain height, it is difficult for the wheels to drive into the fixed position 201. To this end, in some embodiments of the present application, the fixing structure 200 also includes a tilting member 212. The fixing seat 210 is provided with a tilting member 212 at least at one end in the first direction X. The tilting member 212 is rotatable around an axis parallel to the first direction X. When the tilting member 212 rotates to one end in the first direction X that abuts against one of the lifting platform 100 and the fixing seat 210, the other end of the tilting member 212 in the first direction X can be separated from the other of the lifting platform 100 and the fixing seat 210, so as to facilitate the wheels to drive into the fixing seat 210 through the rotating tilting member 212.

[0088] Specifically, during the rotation of the tilting member 212, one end of the tilting member 212 in the first direction X can abut against the jacking platform 100, and at this time, the wheel can drive from the jacking platform 100 to one end of the tilting member 212 and can continue to move along the tilting member 212. After the wheel drives from one end of the tilting member 212 to the other end, under the action of the gravity of the wheel, the other end of the tilting member 212 will rotate toward the fixing seat 210, and finally the other end of the tilting member 212 in the first direction X can abut against the fixing seat 210. After that, the wheel continues to move, and can drive from the other end of the tilting member 212 into the fixing seat 210, and finally move to the fixing position 201.

[0089] In some embodiments, the fixed structure 200 is further provided with a reset member 213, and the reset member 213 is installed on the end of the tilting member 212 away from the fixed position 201 in the first direction X. Because the reset member 213 is provided, the weight of the end of the tilting member 212 away from the fixed position 201 is greater than that of the end of the rotating member close to the fixed position 201. Therefore, when the tilting member 212 is not subjected to external force, for example, after the wheel leaves the fixed structure 200, the end of the tilting member 212 away from the fixed position 201 will rotate under the weight of the reset member 213 until it is against the jacking platform 100 to complete the reset of the rotating member, thereby facilitating the wheel to drive into the fixed position 201 through the rotating member next time.

[0090] In actual use, if only the position of the vehicle needs to be fixed, one of the wheels can be fixed through the above-mentioned fixing structure 200 to complete the fixation of the vehicle's position. However, in some vehicle inspection items, each wheel needs to be fixed, such as durability testing of the vehicle's suspension.

[0091] To this end, in some embodiments of the present application, the fixing structure 200 includes a plurality of fixing structures 200, so that each wheel of the vehicle is fixed respectively by the plurality of fixing structures 200. Among them, since the distances between the wheels of different types of vehicles are different, in order to improve the adaptability of the fixing device to different types of vehicles, the fixing seat 210 of each fixing structure 200 is movable along the first direction X, so as to adjust the position of the fixing structure 200 relative to the jacking platform 100 in the first direction X to adapt to the wheels of different types of vehicles.

[0092] It should be noted that only part of the fixed structure 200 may be movable relative to the jacking platform 100, while the other part remains fixed. In other embodiments, the fixing seat 210 of at least part of the fixed structure 200 is movable relative to the jacking platform 100 along the second direction Y to adjust the position of the fixed structure 200 relative to the jacking platform 100 in the second direction Y. In some other embodiments, at least part of the fixed structure 200 is movable relative to the jacking platform 100 in both the first direction X and the second direction Y. Regardless of whether the fixed structure 200 moves along the first direction X or the second direction Y, it can adapt to the wheels of different vehicles.

[0093] In some embodiments, each fixed structure 200 further includes a locking member 214, which is mounted on the fixed seat 210 and can be controlled to be locked and separated from the jacking platform 100. In this way, when the fixed structure 200 moves to a desired position relative to the jacking platform 100, the fixed seat 210 of the fixed structure 200 can be locked with the jacking platform 100 by the locking member 214, so that the fixed structure 200 can be kept in this position, preventing the fixed structure 200 from moving on its own and affecting the detection results.

[0094] Specifically in the embodiment, the jacking platform 100 includes two longitudinal beams 121 which are arranged at intervals along the second direction Y and extend longitudinally along the first direction X. A plurality of fixed structures 200 are arranged on each longitudinal beam 121, and a sliding groove 216 is provided on the fixed seat 210 on each fixed structure 200. The longitudinal beam 121 is penetrated by the sliding groove 216, and the fixed seat 210 moves along the first direction X on the longitudinal beam 121 through the sliding groove 216.

[0095] Among them, the locking piece is a bolt, and a nut 215 and a locking hole 219 connected to the nut 215 and the sliding groove 216 are fixed on the fixing seat 210. The bolt is threadedly connected with the nut 215 and is passed through the locking hole 219 and passes through the sliding groove 216. When it is necessary to lock the locking piece 214 and the lifting platform 100, the bolt can be rotated until the bolt abuts against the longitudinal beam 121 in the sliding groove 216, so that the longitudinal beam 121 and the bolt are locked with each other, thereby completing the locking of the locking piece 214 and the lifting platform 100.

[0096] In some embodiments of the present application, referring to Figure 1 , Figure 6 and Figure 7 , the lifting platform 100 includes a lifting member 110 and a support member 120. The support member 120 is installed on the lifting member 110 and is provided with the longitudinal beam 121 as described above. The lifting member 110 can controllably drive the support member 120 to move along the third direction Z. The fixed seat 210 is fixedly installed on the support member 120. When the vehicle drives onto the support member 120 and the wheels are fixed by the fixing structure 200, the lifting member 110 is activated to drive the support member 120 to move along the third direction Z, thereby lifting the vehicle to repair the chassis of the vehicle.

[0097] Optionally, the lifting member 110 is a plurality of hydraulic rods arranged at the bottom of the support member 120. The movable ends of the hydraulic rods are connected to the bottom of the support member 120 to drive the support member 120 to move along the third direction Z through the plurality of hydraulic rods.

[0098] Since the support member 120 is arranged at the top of the lifting member 110, the support member 120 has a certain height relative to the ground, and it is impossible or inconvenient for the vehicle to directly drive onto the support member 120. For this reason, in some embodiments, the fixing device further includes a guiding member 130. The guiding member 130 is arranged at at least one end of the support member 120 in the first direction X. One end of the guiding member 130 in the first direction X is connected to the support member 120, and the other end is inclined towards the bottom of the lifting member 110.

[0099] During actual use, when the vehicle needs to drive onto the support member 120, the lifting member 110 can be driven first to lower the support member 120 until the guiding member 130 contacts the ground. The inclined guiding member 130 can guide the vehicle to drive onto the support member 120.

[0100] When the vehicle is driving on the inclined guiding member 130, due to factors such as tire grip, the wheels will slip on the guiding member 130, resulting in the vehicle being unable to drive onto the support member 120. For this reason, in some specific embodiments, a plurality of anti-slip grooves 131 are formed on the guiding member 130. The plurality of anti-slip grooves 131 are arranged in sequence along the first direction X. When the tire passes through the anti-slip grooves 131, part of the tire is embedded in the anti-slip grooves 131 to increase the friction between the tire and the guiding member 130, thereby avoiding the tire from slipping on the guiding member 130.

[0101] In some other embodiments, a plurality of anti-slip members 132 are further protrudingly provided on the guide member 130. The plurality of anti-slip members 132 are arranged in sequence along the first direction X, so as to increase the friction between the tire and the guide member 130 through the protrudingly provided anti-slip members 132, and avoid the tire from slipping on the guide member 130. It should be noted that, in some other embodiments, the anti-slip grooves 131 and the anti-slip members 132 may also be provided on the guide member 130 at the same time, so as to further avoid the tire from slipping on the guide member 130.

[0102] In some embodiments, the lifting platform 100 further includes a base 140 and a protection member 141. A lifting member 110 is provided on the base 140. The protection member 141 is inclined relative to the third direction Z, and both ends of the protection member 141 are respectively abutted against the base 140 and the support member 120. The lifting platform 100 further includes a diagonal brace 142. One end of the diagonal brace 142 is installed on the base 140, and the other end is abutted against the support member 120. In this way, a triangular structure is formed among the diagonal brace 142, the protection member 141 and the base 140, so that the protection member 141 has sufficient support strength to support the support member 120, and avoid the situation that the support member 120 sags under the weight of the vehicle, thereby improving the safety of the lifting platform 100 when lifting the vehicle.

[0103] Specifically, in some embodiments, one end of the protection member 141 is rotatably installed on the base 140 around an axis parallel to the second direction Y, and a plurality of support holes 143 are sequentially formed in the base 140 along the first direction X. One end of the diagonal brace 142 can be inserted into one of the support holes 143.

[0104] When the support member 120 is lifted to different heights by the lifting member 110, the inclination angle of the protection member 141 can be changed by rotating the protection member 141, so that the other end of the protection member 141 can be abutted against the support member 120. After that, the inclination angle of the diagonal brace 142 can be changed by inserting the diagonal brace 142 into different support holes 143, so that a triangular structure can continue to be formed among the diagonal brace 142, the protection member 141 and the base 140.

[0105] The embodiment of the present application further provides a detection device, which includes the fixing device in any of the above embodiments. The detection device is used to detect a vehicle, and can effectively fix the vehicle through the above fixing device during the detection process. Further, since the detection device includes all the technical features of the above fixing device, therefore, the detection device has all the technical effects of the above fixing device, which will not be elaborated here.

[0106] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0107] The above embodiments only express several implementation manners of the present application. The description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
