[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0046] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases.

[0048] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0049] When assembling an axle, different fixtures are usually used to pick up and transport components such as the left axle housing, right axle housing, and motor respectively. For example, when picking up and transporting the left axle housing, a jaw adapted to the left axle housing is required to pick up the left axle housing, and when picking up the motor, a jaw adapted to the motor needs to be replaced for picking up. As a result, when assembling the axle, different jaws need to be replaced according to the different components being picked up, which is time-consuming and laborious, resulting in a less compact assembly rhythm for the axle, poor assembly efficiency, and a relatively high assembly cost for the axle.

[0050] Based on this, the embodiments of the present application disclose a fixture and an axle assembly device, which can pick up different components in the axle, making the assembly rhythm of the axle relatively compact, effectively improving the assembly efficiency of the axle, and being able to effectively save costs.

[0051] The technical solution of the present application will be described in detail below in conjunction with specific embodiments and drawings.

[0052] Embodiment 1

[0053] The embodiment of the present application provides a fixture for clamping an axle. The axle includes a left axle housing, a drive module, and a right axle housing. As Figures 1 - 5 shown, the fixture 100 includes a bracket 10 and a jaw module 20. Among them, the jaw module 20 includes a first jaw 2, a second jaw 3, and a third jaw 4 that are spaced apart on the bracket 10. The first jaw 2 is used to clamp the left axle housing, the second jaw 3 is used to clamp the drive module, and the third jaw 4 is used to clamp the right axle housing.

[0054] In this embodiment, the left axle housing is clamped by the first jaw 2 in the fixture 100, the drive module is clamped by the second jaw 3, and the right axle housing is clamped by the third jaw 4. Compared with using different fixtures 100 to clamp the left axle housing, right axle housing, and drive module respectively, when picking up and clamping the left axle housing, right axle housing, and drive module in the axle, it is possible to clamp the left axle housing, right axle housing, and drive module without replacing the fixture 100, which is time-saving and laborious, enabling the assembly of the axle to have a relatively compact rhythm, effectively improving the assembly efficiency of the axle, and also effectively reducing the number of fixtures 100 and saving costs.

[0055] Among them, the drive module may include at least one of a motor, a reducer, a differential, etc., and is not limited herein.

[0056] In addition, the first jaw 2, the second jaw 3, and the third jaw 4 are spaced apart on the bracket 10. It may be that the first jaw 2, the second jaw 3, and the third jaw 4 are spaced along the length direction of the bracket 10, so that when the left axle housing, drive module, and right axle housing are clamped by the first jaw 2, the second jaw 3, and the third jaw 4 respectively, interference is less likely to occur.

[0057] Optionally, as Figure 2 and Figures 6 - 8 shown, the left axle housing includes a suspension portion and a flared portion. The jaw module 20 further includes a fourth jaw 5. The fourth jaw 5 is used to cooperate with the first jaw 2 to grip the left axle housing. The fourth jaw 5 is located between the first jaw 2 and the second jaw 3. The first jaw 2 is used to grip the suspension portion. The gripping surface of the first jaw 2 is adapted to the outer surface of the suspension portion. The fourth jaw 5 is used to grip the flared portion. The gripping surface of the fourth jaw 5 is adapted to the outer surface of the flared portion.

[0058] Thus, by the cooperation of the fourth jaw 5 and the first jaw 2 to grip the left axle housing, with the first jaw 2 used to grip the suspension portion of the left axle housing and the fourth jaw 5 used to grip the flared portion of the left axle housing, the fixture 100 can grip the left axle housing more firmly.

[0059] Among them, the gripping surface of the first jaw 2 is adapted to the outer surface of the suspension portion. It should be understood that if the outer surface of the suspension portion is a plane, the gripping surface of the first jaw 2 can be a plane; if the outer surface of the suspension portion is an arc surface, the gripping surface of the first jaw 2 can be an arc surface, so that the first jaw 2 can grip the suspension portion more firmly. Similarly, the gripping surface of the fourth jaw 5 is adapted to the outer surface of the flared portion, that is, the shape of the gripping surface of the fourth jaw 5 is adapted to the shape of the outer surface of the flared portion, so that the fourth jaw 5 can grip the flared portion more firmly.

[0060] Optionally, as Figures 6 - 8 shown, the gripping surface of the first jaw 2 can be a plane, and the gripping surface of the fourth jaw 5 can be a concave arc surface.

[0061] Thus, while the first jaw 2 and the fourth jaw 5 can both grip the left axle housing more firmly, they can also be more easily distinguished by the different gripping surfaces when installing the first jaw 2 and the fourth jaw 5, which facilitates the installation of the first jaw 2 and the fourth jaw 5.

[0062] It should be explained that the gripping surface of the first jaw 2 being a plane means that the gripping surface of the first jaw 2 is approximately a plane. It can be that the gripping surface of the first jaw 2 is in the same plane, or it can include multiple planes located in different planes. There is no limitation here.

[0063] The gripping surface of the fourth jaw 5 being a concave arc surface means that the gripping surface of the fourth jaw 5 is approximately a concave arc surface. It can be that most of the gripping surface of the fourth jaw 5 is a concave arc surface and a small part is a plane, or it can be that the gripping surface of the fourth jaw 5 includes multiple arc surfaces that are smoothly connected in sequence, or it can be that the gripping surface of the fourth jaw 5 is a single concave arc surface. There is no limitation here.

[0064] The above-mentioned first jaw 2, second jaw 3, third jaw 4 and fourth jaw 5 can be implemented in various ways. In one possible implementation, it may include two clamping members arranged oppositely and a driving member connected to the clamping members. The driving member is used to drive the two clamping members to approach or separate from each other, and the structure is simple and easy to implement.

[0065] In another possible implementation, as Figures 6 - 10 shown, at least one of the first jaw 2, second jaw 3, third jaw 4 or fourth jaw 5 includes a base 21, a first clamping member 22a, a second clamping member 22b, a driving member 23 and a locking member 24. Among them, the base 21 is connected to the bracket 10; the first clamping member 22a and the second clamping member 22b are arranged oppositely and slidably arranged on the base 21; the driving member 23 is connected to the first clamping member 22a and the second clamping member 22b, and is used to drive the first clamping member 22a and the second clamping member 22b to approach or separate from each other; the locking member 24 is arranged on the base 21 and is connected to at least one of the first clamping member 22a and the second clamping member 22b. The locking member 24 is used to lock the positions of the first clamping member 22a and the second clamping member 22b when the first clamping member 22a and the second clamping member 22b clamp the axle housing.

[0066] Thus, by locking the positions of the first clamping member 22a and the second clamping member 22b by the locking member 24 when the first clamping member 22a and the second clamping member 22b clamp the axle housing, the probability of the axle housing falling off after being clamped by the fixture 100 can be effectively reduced. For example, the probability of the first jaw 2 accidentally falling off after clamping the left axle housing can be effectively reduced, so that the fixture 100 can drive the left axle housing, right axle housing or drive module to move more stably after clamping the left axle housing, right axle housing or drive module, and the fixture 100 can have a better clamping effect.

[0067] It should be noted that at least one of the above-mentioned first jaw 2, second jaw 3, third jaw 4 or fourth jaw 5 includes a base 21, a first clamping member 22a, a second clamping member 22b, a driving member 23 and a locking member 24, which means that any one of the first jaw 2, second jaw 3, third jaw 4 and fourth jaw 5 includes a base 21, a first clamping member 22a, a second clamping member 22b, a driving member 23 and a locking member 24, or any two of the first jaw 2, second jaw 3, third jaw 4 and fourth jaw 5 include a base 21, a first clamping member 22a, a second clamping member 22b, a driving member 23 and a locking member 24, or any three of the first jaw 2, second jaw 3, third jaw 4 and fourth jaw 5 include a base 21, a first clamping member 22a, a second clamping member 22b, a driving member 23 and a locking member 24, or all of the first jaw 2, second jaw 3, third jaw 4 and fourth jaw 5 include a base 21, a first clamping member 22a, a second clamping member 22b, a driving member 23 and a locking member 24.

[0068] The above-mentioned base 21 can be any one of a plate-like structure, a frame structure, a block structure, etc., and is not limited herein.

[0069] The locking member 24 is connected to at least one of the first clamping member 22a and the second clamping member 22b. It can be that the locking member 24 is connected to both the first clamping member 22a and the second clamping member 22b, or the locking member 24 is connected to the first clamping member 22a, or the locking member 24 is connected to the second clamping member 22b, and is not limited herein.

[0070] Optionally, as Figure 6 and Figure 7 shown, the driving member 23 is arranged on the second clamping member 22b, the driving end of the driving member 23 is connected to the first clamping member 22a, and the driving member 23 is used to drive the first clamping member 22a to move in a direction close to the second clamping member 22b. When the first clamping member 22a moves to abut against the axle, the driving member 23 can drive the second clamping member 22b to move in a direction close to the first clamping member 22a.

[0071] Thus, the driving member 23 can first drive the first clamping member 22a to move in a direction close to the second clamping member 22b. After the first clamping member 22a moves in place, it can drive the second clamping member 22b to move in a direction close to the first clamping member 22a, making the operation of driving the first clamping member 22a and the second clamping member 22b to approach each other to clamp the axle by the driving member 23 relatively simple and easy to implement.

[0072] Among them, the driving member 23 is used to drive the first clamping member 22a to move towards the second clamping member 22b. When the first clamping member 22a moves to abut against the axle, the driving member 23 can drive the second clamping member 22b to move towards the first clamping member 22a. It should be understood that during the process of the driving member 23 driving the first clamping member 22a to move, the second clamping member 22b is allowed to have a small amount of movement. Alternatively, during the movement of the first clamping member 22a, the second clamping member 22b remains stationary all the time, and it is after the first clamping member 22a moves to abut against the axle that the second clamping member 22b moves.

[0073] The above-mentioned situation that when the first clamping member 22a moves to abut against the axle, the driving member 23 can drive the second clamping member 22b to move towards the first clamping member 22a can have various implementation manners. In one possible implementation manner, a stop member is telescopically arranged on the base 21, and the stop member is located on the side of the second clamping member 22b facing the first clamping member 22a. When the driving member 23 drives the first clamping member 22a to move towards the second clamping member 22b, the stop member can extend and abut against the second clamping member 22b to prevent the second clamping member 22b from moving towards the first clamping member 22a. After the first clamping member 22a moves to abut against the axle, the stop member can retract. At this time, the driving member 23 can drive the second clamping member 22b to move towards the first clamping member 22a.

[0074] In another possible implementation manner, the sum of the weights of the second clamping member 22b and the driving member 23 is greater than the weight of the first clamping member 22a.

[0075] Thus, the frictional resistance between the second clamping member 22b and the base 21 can be made greater than the frictional resistance between the first clamping member 22a and the base 21. Therefore, when the driving member 23 drives the first clamping member 22a and the second clamping member 22b to approach each other, the first clamping member 22a can move first, and the second clamping member 22b can move later. Without adding other additional structural members, the structure of the fixture 100 can be relatively simple and easy to implement.

[0076] Among them, the structures of the first clamping member 22a and the second clamping member 22b can be substantially the same. For example, they can both include a connecting plate and a clamping portion arranged on the connecting plate. Since the driving member 23 is arranged on the second clamping member 22b, thus, the sum of the weights of the second clamping member 22b and the driving member 23 can be made greater than the weight of the first clamping member 22a, reducing the manufacturing difficulty of the first clamping member 22a and the second clamping member 22b.

[0077] The above-mentioned driving member 23 can be any one of a cylinder, an electric cylinder, a combination of a motor and a screw nut, etc., and is not limited herein.

[0078] Optionally, such asFigure 6 and Figure 7 As shown in Figure 7 , when the driving member 23 includes a cylinder, an extension arm 25 is connected between the telescopic end of the cylinder and the first clamping member 22a, and the locking member 24 is used to lock the extension arm 25 when the first clamping member 22a and the second clamping member 22b clamp the axle housing.

[0079] Thus, by connecting the extension arm 25 between the telescopic end of the cylinder and the first clamping member 22a, compared with directly connecting the telescopic end of the cylinder to the first clamping member 22a, when the first clamping member 22a and the second clamping member 22b move away from each other, they can have a larger distance, enabling the first clamping member 22a and the second clamping member 22b to also clamp relatively large left axle housings, drive modules, etc.

[0080] Moreover, the locking member 24 is used to lock the extension arm 25 when the first clamping member 22a and the second clamping member 22b clamp the axle housing, allowing the locking member 24 to have a larger setting range at the position of the base 21, which facilitates the setting of the locking member 24.

[0081] In addition, the driving member 23 includes a cylinder. By driving the first clamping member 22a and the second clamping member 22b to move closer to or away from each other through the cylinder, the movement of the first clamping member 22a and the second clamping member 22b can be relatively stable and fast, and the driving member 23 is easy to maintain, reducing the cost of the fixture 100.

[0082] Wherein, the extending direction of the extension arm 25 is the same as the extending direction of the telescopic rod of the cylinder, and the cylinder and the extension arm 25 can be arranged oppositely along the telescopic direction of the telescopic rod of the cylinder. While enabling the first clamping member 22a and the second clamping member 22b to have a larger distance when moving away from each other, it also allows the extension arm 25 to be connected between the extending end of the cylinder and the first clamping member 22a with a shorter length, saving costs. Additionally, the sum of the weights of the first clamping member 22a and the extension arm 25 is less than the sum of the weights of the second clamping member 22b and the driving member 23.

[0083] When the driving member 23 drives the first clamping member 22a and the second clamping member 22b to clamp the axle housing, such as when clamping the left axle housing, the cylinder is started. The telescopic end of the cylinder retracts, driving the extension arm 25 to move towards the direction close to the second clamping member 22b, thereby driving the first clamping member 22a to move towards the direction close to the second clamping member 22b until the first clamping member 22a abuts against the left axle housing. The telescopic end of the cylinder continues to retract, driving the second clamping member 22b to move towards the direction close to the first clamping member 22a until the second clamping member 22b abuts against the left axle housing. Then, the cylinder stops working, and the locking member 24 locks the extension arm 25 to prevent the first clamping member 22a and the second clamping member 22b from loosening easily during the process of clamping the left axle housing.

[0084] When the driving member 23 drives the first clamping member 22a and the second clamping member 22b to release the clamping of the left axle housing or the like, first, the locking member 24 releases the locking of the extending arm 25, and then the air cylinder is started. The telescopic end of the air cylinder extends, driving the extending arm 25 to move away from the second clamping member 22b, thereby driving the first clamping member 22a to move away from the second clamping member 22b until the first clamping member 22a moves to a preset position. The telescopic end of the air cylinder continues to extend, driving the second clamping member 22b to move away from the first clamping member 22a until the second clamping member 22b moves to a preset position to realize the clamping of the left axle housing or the like.

[0085] The above-mentioned locking member 24 can have various implementation manners. In a possible implementation manner, the locking member 24 can include a locking bolt. A first locking through hole can be provided on the first clamping member 22a, and a plurality of second locking through holes can be provided on the base 21. When the first clamping member 22a and the second clamping member 22b clamp the axle, the locking bolt can be sequentially passed through the first locking through hole and the second locking through hole to lock and fix the first clamping member 22a on the base 21. At this time, the driving member 23 is in a stopped working state. When the first clamping member 22a is fixed, the second clamping member 22b can also be fixed relative to the base 21, so that the parts of the axle can be clamped more stably.

[0086] In another possible implementation manner of the locking member 24, as Figure 6 and Figure 7 shown, the locking member 24 can include an air lock, and the extending arm 25 is passed through the locking hole of the air lock.

[0087] Thus, the locking member 24 can quickly perform a locking operation on the extending arm 25, and the locking of the extending arm 25 has high reliability, effectively preventing the first clamping member 22a and the second clamping member 22b from loosening or falling off during the process of clamping the left axle housing, the driving module or the right axle housing.

[0088] Optionally, as Figure 6 、 Figure 7 and Figure 11 shown, the base 21 is provided with limiting members 26a at both opposite ends in the relative direction of the first clamping member 22a and the second clamping member 22b. The limiting members 26a are used to limit the positions of the first clamping member 22a and the second clamping member 22b when they move away from each other.

[0089] Thus, it can effectively prevent the first clamping member 22a and the second clamping member 22b from sliding out of the base 21 when moving away from each other. At the same time, it can also facilitate the control of the driving distance of the driving member 23 to drive the first clamping member 22a and the second clamping member 22b.

[0090] Among them, the limiting member 26a can be a limiting plate provided on the base 21, or a limiting block provided on the base 21, or a limiting rod provided on the base 21, which is not limited herein.

[0091] The above-mentioned limiting member 26a is used to limit the positions of the first clamping member 22a and the second clamping member 22b when they move away from each other. Exemplarily, when the driving member 23 drives the first clamping member 22a and the second clamping member 22b to move away from each other, the driving member 23 can first drive the first clamping member 22a to move in a direction away from the second clamping member 22b until the first clamping member 22a abuts against the corresponding limiting member 26a. Then, the driving member 23 continues to work, driving the second clamping member 22b to move in a direction away from the first clamping member 22a until the second clamping member 22b abuts against the corresponding limiting member 26a, and the driving member 23 stops working.

[0092] As Figure 6 、 Figure 7 and Figure 11 shown, buffer members 26b are also provided at both opposite ends of the base 21 along the relative direction of the first clamping member 22a and the second clamping member 22b. The buffer members 26b are used to contact the first clamping member 22a to buffer the first clamping member 22a before the first clamping member 22a abuts against the corresponding limiting member 26a, and to contact the second clamping member 22b to buffer the second clamping member 22b before the second clamping member 22b abuts against the corresponding limiting member 26a.

[0093] Thus, the first clamping member 22a can be buffered before abutting against the corresponding limiting member 26a, and the second clamping member 22b can be buffered before abutting against the corresponding limiting member 26a, effectively preventing a large impact force from being generated between the first clamping member 22a and the second clamping member 22b and the corresponding limiting member 26a due to the relatively fast moving speeds of the first clamping member 22a and the second clamping member 22b, and avoiding damage to the first clamping member 22a and the second clamping member 22b due to a large impact force.

[0094] Among them, the buffer member 26b can be any one of a spring, a foam, a buffer, etc., which is not limited herein.

[0095] In addition, along the relative direction of the first clamping member 22a and the second clamping member 22b, the buffer member 26b and the limiting member 26a on the same end of the base 21, the end of the buffer member 26b facing the first clamping member 22a or the end facing the second clamping member 22b should protrude beyond the limiting member 26a.

[0096] Optionally, as Figure 6 and Figure 7As shown, the locking member 24 is electrically connected to a detection member 27, and the detection member 27 is used to detect the position of the first clamping member 22a, or to detect the position of the second clamping member 22b, or, to detect the positions of the first clamping member 22a and the second clamping member 22b.

[0097] Thus, the position of the first clamping member 22a and / or the second clamping member 22b can be detected by the detection member 27. When the first clamping member 22a abuts against the left axle housing, the drive module, or the right axle housing, and when the second clamping member 22b abuts against the left axle housing, the drive module, or the right axle housing, it is possible to more accurately determine whether the first clamping member 22a and the second clamping member 22b clamp the left axle housing, the drive module, or the right axle housing, so that the locking member 24 can lock and fix the first clamping member 22a in a more timely manner, effectively preventing the left axle housing, the drive module, or the right axle housing from falling off due to the loose clamping of the first clamping member 22a and the second clamping member 22b. At the same time, it can also effectively prevent the left axle housing, the drive module, or the right axle housing from being damaged due to the tight clamping of the first clamping member 22a and the second clamping member 22b.

[0098] Among them, the locking member 24 is electrically connected to the detection member 27. After the detection member 27 detects that the positions of the first clamping member 22a and / or the second clamping member 22b meet the requirements, a signal can be transmitted to the locking member 24, and then the locking member 24 can lock the first clamping member 22a or the extension arm 25 connected to the first clamping member 22a.

[0099] In addition, the detection member 27 can include a proximity switch. Thus, the detection of the detection member 27 can have a faster response speed and higher reliability, effectively improving the clamping accuracy of the first clamping member 22a and the second clamping member 22b.

[0100] The detection member 27 can be arranged on the first clamping member 22a, or on the second clamping member 22b, or, both the first clamping member 22a and the second clamping member 22b are provided with the detection member 27, which is not limited herein and can be specifically set according to the actual situation.

[0101] In some embodiments, as Figure 3 and Figure 7 shown, the interior of the bracket 10 can have a receiving space 1, and at least one of the driving member 23 or the locking member 24 is located in the receiving space 1, and the base 21 is arranged on the upper surface of the bracket 10.

[0102] Thus, the structure of the fixture 100 can be made relatively compact, reducing the occupied space of the fixture 100. Moreover, the center of mass of the fixture 100 can be made relatively low, so that when the fixture 100 is assembled on the robot, the center of mass of the fixture 100 can be relatively close to the robot, thereby reducing the load on the robot.

[0103] Among them, at least one of the driving member 23 or the locking member 24 is located in the accommodating space 1. It can be that the driving member 23 is located in the accommodating space 1, or the locking member 24 is located in the accommodating space 1, or both the driving member 23 and the locking member 24 are located in the accommodating space 1.

[0104] In addition, when the driving member 23 includes a cylinder and an extension arm 25 is connected between the telescopic end of the cylinder and the first clamping member 22a, the extension arm 25 is also located in the accommodating space 1.

[0105] As Figures 6 - 9 shown, the above-mentioned first clamping member 22a and second clamping member 22b both include a moving part 222 and at least one clamping part 221 provided on the moving part 222. The number of the clamping parts 221 of the first clamping member 22a corresponds to the number of the clamping parts 221 of the second clamping member 22b. And when both the first clamping member 22a and the second clamping member 22b include a plurality of clamping parts 221, the plurality of clamping parts 221 are arranged in a horizontal direction perpendicular to the direction in which the first clamping member 22a and the second clamping member 22b face each other.

[0106] Thus, the clamping of the components in the axle by the first clamping member 22a and the second clamping member 22b can be relatively firm, such as the clamping of the drive module can be relatively firm.

[0107] Among them, when the plurality of clamping parts 221 are arranged in a horizontal direction perpendicular to the direction in which the first clamping member 22a and the second clamping member 22b face each other, they can be arranged at intervals, so as to be able to clamp the components in the axle relatively firmly while reducing the number of the clamping parts 221 and saving costs.

[0108] In addition, when both the first clamping member 22a and the second clamping member 22b include a plurality of clamping parts 221, the number of the clamping parts 221 can be two, three or more, which is not limited herein, and can be specifically selected according to the actual situation.

[0109] The above-mentioned first clamping member 22a and second clamping member 22b are slidably arranged on the base 21. For example, a slide rail 28 can be arranged on the base 21, and the slide rail 28 extends along the direction in which the first clamping member 22a and the second clamping member 22b face each other. Sliders 29 are arranged on both the first clamping member 22a and the second clamping member 22b, and the sliders 29 are slidably connected to the slide rail 28, so that both the first clamping member 22a and the second clamping member 22b can slide relative to the base 21 smoothly.

[0110] In some other embodiments, the present application also discloses an axle assembly device, including a robot and the fixture 100 described in any one of the above embodiments. The bracket 10 of the fixture 100 is connected to the free end of the robot.

[0111] Thus, the robot and the fixture 100 cooperate to pick up, transport, and place different components in the axle. For example, it can pick up, transport, and place the left axle housing in the axle, can also pick up, transport, and place the right axle housing, and can also pick up, transport, and place the drive module, enabling the assembly of the axle to have a relatively compact rhythm, effectively improving the assembly efficiency of the axle and saving costs.

[0112] In addition, the fixture 100 in this axle assembly device is the fixture 100 in the above embodiments. Therefore, the fixture 100 in the axle assembly device has substantially the same technical effects as the fixture 100 in the above embodiments. Since the fixture 100 has been described in detail in the above embodiments, it will not be elaborated here.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
