Description

Technical Field

[0001] The present invention belongs to the field of battery swapping station equipment, and particularly relates to a channel opening and closing device and a battery swapping station including the same. Background Art

[0002] In current battery swapping stations, to ensure the safety of the charging area connected to the battery swapping area, a channel opening and closing device is usually provided at the connection position between the two (i.e., the channel opening for the battery swapping shuttle to travel). The channel opening and closing device realizes the opening and closing of the channel opening by driving the lifting door to rise and fall. To enable the reliable lifting and lowering of the lifting door, guiding mechanisms are usually provided on both sides of the door frame forming the channel opening. By connecting with the lifting door, the guiding of the lifting door is realized. However, due to processing errors or on-site installation problems, the two sides of the door frame forming the channel opening are often non-parallel, with a certain parallelism error, that is, the distance between the two side door frames gradually increases or decreases in the height direction. This results in the guiding mechanisms installed on both sides of the door frame being non-parallel. During the lifting and lowering process of the lifting door, the guiding of the lifting door by the guiding mechanisms on both sides is also non-parallel, and there is a possibility of jamming during the lifting process. Even by increasing the driving force applied to the lifting door to avoid jamming, the connection between the lifting door and the guiding mechanism will eventually be damaged due to unbalanced forces. Therefore, the non-parallel error of the door frame of the channel opening easily leads to the jamming of the lifting door during movement or the damage of the lifting door and the guiding mechanism, which may increase the additional maintenance and repair costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects that the lifting door is prone to jamming and damage during the lifting process due to the non-parallelism of the two sides of the door frame in the prior art, and to provide a channel opening and closing device and a battery swapping station including the same.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A channel opening and closing device, the channel opening and closing device includes a channel opening for the battery swapping equipment to enter and exit the charging area, a mounting door frame, and a lifting door provided on the mounting door frame and capable of opening and closing the channel opening. The channel opening and closing device is characterized in that the channel opening and closing device further includes:

[0006] A lifting guiding mechanism, the lifting guiding mechanism includes a slide rail and a slider. Two slide rails are respectively arranged on both sides of the mounting door frame along the width direction along the lifting direction of the lifting door, and the slider is slidably arranged in the corresponding slide rail;

[0007] A floating connection mechanism, the floating connection mechanism corresponds to the lifting guiding mechanism one by one. The slider is connected to the lifting door through the floating connection mechanism, and the floating connection mechanism has a degree of freedom of movement in the width direction of the lifting door relative to the lifting door.

[0008] In this technical solution, slide rails are arranged on both sides of the installation door frame along the width direction, and the lifting door is guided by means of slide rail sliders, reducing the vibration and sway generated during the movement of the lifting door. On this basis, a floating connection mechanism corresponding to the slider is set up, and the floating connection mechanism is connected to the lifting door. By virtue of the freedom of movement along the width direction of the lifting door between the floating connection mechanism and the lifting door, the error of non-parallelism of the two slide rails caused by the parallelism problem on both sides of the installation door frame can also be released through the movement along the width direction between the floating connection mechanism and the lifting door, effectively avoiding the jamming or damage of the lifting door. At the same time, the floating connection mechanism still remains connected to the lifting door in the height direction, and the lifting accuracy of the lifting door will not be affected. Therefore, through this structural setting scheme, the service durability of the channel opening and closing device can be improved, and the maintenance cost is reduced.

[0009] Preferably, the floating connection mechanism includes a first installation part extending along the width direction of the lifting door. A waist-shaped hole extending along the width direction of the lifting door is arranged on the surface of the first installation part, and a connecting part extending out from the surface of the lifting door passes through and is positioned in the waist-shaped hole.

[0010] In this technical solution, a waist-shaped hole structure extending along the width direction of the lifting door is used to connect with the connecting part extending out from the surface of the lifting door, so as to obtain a flexible adjustment margin along the width direction through a relatively simple structural design. When the distance between the installation door frames changes, the lifting door can be adjusted by itself through the design form of the waist-shaped hole to adapt to different distances, enhancing the flexibility of the lifting door adjustment.

[0011] Preferably, the lifting door includes a lifting door body, an installation bracket and a screw. The installation bracket is arranged on the surface of the lifting door body and extends outwards. A threaded hole is provided on the installation bracket, and the screw passes through the waist-shaped hole of the floating connection mechanism and is then threadedly connected to the threaded hole to form a connecting part passing through and positioned in the waist-shaped hole.

[0012] In this technical solution, the floating connection is realized by passing the screw through the waist-shaped hole and connecting it to the lifting door body. The purpose of reliable connection is achieved through a relatively simple structure. Moreover, the connection method of screw and nut has a simple structure and is easy to maintain, and has high structural strength, which can meet the connection strength requirements between the floating connection mechanism and the lifting door. In addition, by setting an installation bracket on the surface of the lifting door body to form a threaded hole, the sealing problem caused by directly opening a hole in the lifting door body is avoided.

[0013] Preferably, a bushing is provided on the screw, and the bushing is sleeved on the screw and located between the waist-shaped holes;

[0014] The threaded hole located on the installation bracket is formed by welding a nut;

[0015] A gasket sleeved on the screw is further provided on the screw, and the gasket is clamped between the screw and the first mounting portion.

[0016] In this technical solution, the design of the bushing helps to reduce the direct friction between the screw and the oblong hole, helps to reduce the wear caused by friction during the adjustment of the lifting door, and extends the service life of the screw and the oblong hole.

[0017] Moreover, welding nuts are used to form threaded holes, which are convenient for processing and have high structural strength, meeting the connection strength requirements between the floating connection mechanism and the lifting door. In addition, since the distance between the mounting bracket and the lifting door is small, in order to make full use of the limited space and ensure the stable connection between the screw and the mounting bracket, welding nuts are selected to be arranged on the side of the mounting bracket facing the lifting door as fixing parts. Such a design can not only optimize the space utilization, ensure that the structure between the screw part, the mounting bracket and the lifting door is more compact, but also ensure the reliable connection between the mounting bracket and the floating connection mechanism.

[0018] At the same time, clamping the gasket between the screw and the first mounting portion can reduce the direct contact between the two, helps to reduce the friction between the two, provides a buffering and protective effect, thereby reducing wear and extending the service life of the screw and the first mounting portion. In addition, the clamping of the gasket also helps to improve the stability between the screw and the first mounting portion, preventing the lifting door from shaking and instability caused by unstable connection during the movement process.

[0019] Preferably, the radial length of the screw is less than the shortest distance between the oblong holes along the height direction of the lifting door;

[0020] And / or, a gap is formed between the screw and the oblong hole.

[0021] In this technical solution, the design with a gap can enable the lifting door to move horizontally by itself in the oblong hole, which is convenient for adjustment, reduces the risk of jamming and blocking caused by the friction between the screw and the oblong hole during the adjustment of the lifting door, helps to ensure the smooth movement and flexible adjustment of the lifting door, and avoids abnormal stagnation due to excessive resistance.

[0022] Preferably, the two slide rails are arranged opposite to each other and are both arranged inside the mounting door frame.

[0023] In this technical solution, the inner side of the mounting door frame is used to arrange the slide rails to reasonably utilize the space and avoid the lifting guide mechanism occupying the space outside the mounting door frame and affecting the arrangement of other devices adjacent to the channel opening and closing device.

[0024] Preferably, the floating connection mechanism further includes a second mounting portion for connecting with the slider, and the second mounting portion and the first mounting portion are arranged in an L shape;

[0025] A reinforcing structure is provided between the first mounting portion and the second mounting portion.

[0026] In this technical solution, the design of arranging the second mounting portion and the first mounting portion in an L-shape to form a bending structure, and the additional arrangement of the reinforcing structure provide a more solid and stable connection method, which helps to improve the reliability and stability of the connection of each component in the floating connection mechanism.

[0027] Preferably, through holes are provided on the surface of the second mounting portion facing the mounting door frame, and the through holes are used for the abutting member to pass through and abut against the slide rail.

[0028] In this technical solution, the design of the through holes allows the setting of abutting members or other fixing devices to fix the lifting door at a specific position relative to the mounting door frame, ensuring a more stable connection between the lifting door and the mounting door frame, preventing the lifting door from accidentally loosening or falling off relative to the mounting door frame during bumpy transportation, and improving the safety during transportation and the integrity of the lifting door and the surrounding environment.

[0029] Preferably, the number of floating connection mechanisms is multiple and they are arranged in pairs on both sides of the lifting door.

[0030] In this technical solution, the floating connection mechanisms arranged in pairs can provide more stable support for the lifting door, preventing the lifting door from tilting or shaking during movement. At the same time, the arrangement of multiple floating connection mechanisms can improve the adjustment flexibility of the lifting door in the horizontal direction. Each floating connection mechanism can be adjusted independently to adapt to the spacing of the mounting door frames at different positions, thereby enhancing the adaptability of the channel opening and closing device. In addition, if a floating connection mechanism on one side fails, it will not completely affect the adjustment of the entire lifting door, and the risk of ineffective adjustment of the channel opening and closing device due to the failure of a certain floating connection mechanism can be reduced, improving the reliability of the floating connection mechanism.

[0031] A battery swapping station includes the channel opening and closing device according to any one of the above.

[0032] In this technical solution, the channel opening and closing device adopting the above structural form can effectively control the opening and closing of the channel in the battery swapping station, provide a flexible operation channel for the battery swapping equipment, and realize safe and orderly battery replacement services.

[0033] The positive and progressive effects of the present invention are as follows:

[0034] 1. The channel opening and closing device arranges slide rails on both sides of the installation door frame along the width direction, and realizes the guidance of the lifting door through the slide rail slider, reducing the vibration and sway generated during the movement of the lifting door. On this basis, by setting a floating connection mechanism corresponding to the slider, connecting the floating connection mechanism with the lifting door, and utilizing the freedom of movement along the width direction of the lifting door between the floating connection mechanism and the lifting door, the error of non-parallelism of the two slide rails caused by the parallelism problem on both sides of the installation door frame can also be released through the movement along the width direction between the floating connection mechanism and the lifting door, effectively avoiding the jamming or damage of the lifting door. At the same time, the floating connection mechanism still maintains a connection with the lifting door in the height direction, and the lifting accuracy of the lifting door will not be affected. Therefore, through this structural setting scheme, the service durability of the channel opening and closing device can be improved, and the maintenance cost can be reduced.

[0035] 2. The battery swapping station adopting the channel opening and closing device with the above structural form can effectively control the opening and closing of the channel in the battery swapping station, provide a flexible operation channel for the battery swapping equipment, and realize safe and orderly battery replacement services.

[0065] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments thereby.

[0066] The present invention provides a battery swapping station for providing battery swapping services to vehicles driving into the battery swapping station. Among them, the battery swapping station includes a battery swapping area and a charging area. The area for vehicles to drive into is the battery swapping area, and battery swapping equipment is provided in the battery swapping area to disassemble and assemble the batteries loaded on the vehicles. After the disassembly and assembly are completed, the battery swapping equipment will drive into the charging area through the passage opening to perform charging operations on the batteries removed from the vehicles. In order to separate the charging area and the battery swapping area while not affecting the normal driving of the battery swapping equipment, a passage opening opening and closing device 100 is also provided at the position of the passage opening 11 of the battery swapping station.

[0067] This embodiment provides a preferred structural setting scheme for the passage opening opening and closing device 100. As Figure 1 shown, by driving the lifting door 13 to lift and lower, the passage opening opening and closing device 100 can close and open the passage opening 11 of the battery swapping station. Among them, in Figure 1 the lifting door 13 of the passage opening opening and closing device 100 is at the lowest point to close the passage opening 11. The passage opening opening and closing device 100 further specifically includes a mounting door frame 12, a lifting and guiding mechanism 14 and a floating connection mechanism 15.

[0068] Regarding the installation of the door frame 12, the structure in this embodiment is as follows Figure 2 As shown, it is usually in the shape of a Chinese character "冂", or it can be in the shape of a Chinese character "口", the lower area inside it encloses the passage opening 11, and the upper area inside it is used to accommodate various driving devices in the passage opening opening and closing device 100, and provide the space required for the lifting door 13 to rise. Among them, due to its large structural size, the constraints of factors such as installation and processing errors, the left and right sides of the installation door frame 12 are not completely parallel, so when the lifting door 13 is slidably positioned on the left and right sides of the installation door frame 12, it is easy to cause the lifting door 13 to get stuck during the lifting process due to the non-parallel position relationship between the two sides, or the maintenance frequency is high due to excessive wear.

[0069] To solve this problem, the present embodiment is provided with a lifting guide mechanism 14, through which the lifting door 13 is slidably positioned on the left and right sides of the door frame 12. Figure 3 As shown, the lifting guide mechanism 14 specifically includes a slide rail 141 and a slider 142. The two slide rails 141 are respectively arranged on the left and right side surfaces of the mounting door frame 12 along the width direction along the lifting direction of the lifting door 13, and the slider 142 is slidably arranged in the corresponding slide rail 141, and the slider 142 is connected to the lifting door 13 to achieve the purpose of moving the lifting door 13 along the extension direction of the slide rail 141, that is, the up and down direction. By arranging the slide rails 141 on both sides of the mounting door frame 12 along the width direction, the lifting door 13 is guided by the slide rails 141 and the slider 142, thereby reducing the vibration and shaking of the lifting door 13 during the movement.

[0070] In order to solve the influence of the non-parallelism of the left and right sides of the door frame 12 on the lifting door 13, a floating connection mechanism 15 is further provided in this embodiment, and the connection between the slider 142 and the lifting door 13 is realized by the floating connection mechanism 15. Specifically, the floating connection mechanism 15 is arranged in a one-to-one correspondence with the slider 142 on the lifting guide mechanism 14, and the slider 142 is connected to the lifting door 13 through the corresponding floating connection mechanism 15, and the floating connection mechanism 15 has a degree of freedom of movement relative to the lifting door 13 in the width direction of the lifting door 13, so that the error of the non-parallelism of the slide rails on both sides caused by the parallelism problem of the two sides of the door frame 12 can also be released by the movement between the floating connection mechanism 15 and the lifting door 13 along the width direction, so as to solve a series of problems caused by the non-parallelism of the two sides from the root, and effectively avoid the lifting door 13 from being stuck or damaged. At the same time, the floating connection mechanism 15 is still connected to the lifting door 13 in the height direction, and the lifting accuracy of the lifting door 13 will not be affected. Therefore, the durability of the channel opening and closing device 100 can be improved through this structural setting scheme, and the maintenance cost can be reduced.

[0071] It should be clearly stated that in this embodiment, as Figure 1 shown, when the lifting door 13 is in the closed state, it completely covers the passage opening 11, so as to effectively prevent personnel and foreign objects from invading the charging area of the battery swapping station, while improving the isolation effect between the charging area and the outside world and meeting the requirements of dust prevention, heat preservation, etc. Of course, in other embodiments, the lifting door 13 can also semi-cover or partially cover the passage opening 11 as needed, and the specific coverage degree can be set according to actual needs.

[0072] As Figure 1 shown, the number of the sliders 142 and the floating connection mechanisms 15 is four each, and they are arranged in pairs on both sides of the lifting door 13. In this embodiment, the sliders 142 and the floating connection mechanisms 15 arranged in pairs can provide more stable support for the lifting door 13, preventing the lifting door 13 from tilting or shaking during movement. At the same time, the setting of multiple floating connection mechanisms 15 can improve the adjustment flexibility of the lifting door 13 in the horizontal direction. Each floating connection mechanism 15 can be adjusted independently to adapt to the spacing of the installation door frames 12 at different positions, thereby enhancing the adaptability of the passage opening opening and closing device 100. In addition, if a floating connection mechanism 15 on one side fails, it will not completely affect the adjustment of the entire lifting door 13, and the risk of ineffective adjustment of the passage opening opening and closing device 100 due to the failure of a certain floating connection mechanism 15 can be reduced, improving the reliability of the floating connection mechanism 15.

[0073] In this embodiment, a specific structural setting scheme of the floating connection mechanism 15 is provided: as Figures 3 - 4 shown, the floating connection mechanism 15 includes a first installation part 151 extending along the width direction of the lifting door 13. A waist-shaped hole 1511 extending along the width direction of the lifting door 13 is arranged on the surface of the first installation part 151. A connecting part extending from the surface of the lifting door 13 passes through and is positioned in the waist-shaped hole 1511. The waist-shaped hole 1511 structure extending along the width direction of the lifting door 13 is used to connect with the connecting part extending from the surface of the lifting door 13, so as to obtain a flexible adjustment margin along the width direction through a relatively simple structural design. When the spacing of the installation door frame 12 changes, the lifting door 13 can be adjusted by itself through the design form of the waist-shaped hole 1511 to adapt to different spacings, enhancing the adjustment flexibility of the lifting door 13.

[0074] Furthermore, as Figures 3 - 4As shown, the lifting door 13 includes a lifting door body 131, a mounting bracket 132, and a screw 133. The mounting bracket 132 is provided on the surface of the lifting door body 131 and extends outward, that is, in the direction towards the first mounting portion 151. A threaded hole is provided in the mounting bracket 132. The screw 133 passes through the waist-shaped hole 1511 of the floating connection mechanism 15 and is then threadedly connected to the threaded hole, that is, connected to the mounting bracket 132, so as to form a connecting portion that passes through and is positioned within the waist-shaped hole 1511. By passing the screw 133 through the waist-shaped hole 1511 and connecting it to the lifting door body 131, floating connection is achieved. The purpose of reliable connection is achieved through a relatively simple structure. Moreover, the connection method of the screw 133 and the nut has a simple structure and is easy to maintain, and has high structural strength, and can meet the connection strength requirements between the floating connection mechanism 15 and the lifting door 13. In addition, by providing the mounting bracket 132 on the surface of the lifting door body 131 to form a threaded hole, the sealing problem caused by directly opening a hole in the lifting door body 131 is avoided.

[0075] Preferably, in this embodiment, the threaded hole located on the mounting bracket 132 is formed by welding a nut 136. Forming the threaded hole by welding the nut 136 is convenient for processing and has high structural strength, meeting the connection strength requirements between the floating connection mechanism 15 and the lifting door 13. In addition, since the distance between the mounting bracket 132 and the lifting door 13 is small, in order to make full use of the limited space and ensure the stable connection between the screw 133 and the mounting bracket 132, it is selected to set the welding nut 136 on the side of the mounting bracket 132 facing the lifting door 13 as a fixing part. Such a design can not only optimize the space utilization, ensure that the structure between the screw 133, the mounting bracket 132 and the lifting door 13 is more compact, but also ensure the reliable connection between the mounting bracket 132 and the floating connection mechanism 15.

[0076] In addition, as Figure 4 shown, a bushing 134 sleeved on the screw 133 and located between the waist-shaped holes 1511 is provided on the screw 133. The design of the bushing 134 helps to reduce the direct friction between the screw 133 and the waist-shaped hole 1511, helps to reduce the wear caused by friction during the adjustment of the lifting door 13, and extends the service life of the screw 133 and the waist-shaped hole 1511.

[0077] Moreover, a gasket 135 sleeving on the screw 133 is further provided on the screw 133. The gasket 135 is clamped between the screw 133 and the first mounting portion 151, which can reduce the direct contact between the two, help reduce the friction therebetween, play a role in buffering and protecting, thereby reducing wear and extending the service life of the screw 133 and the first mounting portion 151. In addition, the clamping of the gasket 135 also helps improve the stability between the screw 133 and the first mounting portion 151, and prevent the shaking and instability caused by the unstable connection during the movement of the lifting door 13.

[0078] As Figure 4 shown, the radial length of the screw 133 is less than the shortest distance between the waist-shaped holes 1511 along the height direction of the lifting door 13. At the same time, a gap is formed between the screw 133 and the waist-shaped holes 1511. That is to say, when the screw 133 is in the waist-shaped holes 1511, gaps between the screw 133 and the waist-shaped holes 1511 are provided along the circumferential direction of the screw 133.

[0079] In this embodiment, the design with gaps can enable the lifting door 13 to move horizontally by itself in the waist-shaped holes 1511, which is convenient for adjustment, reduce the risk of jamming and blocking caused by the friction between the screw 133 and the waist-shaped holes 1511 during the adjustment of the lifting door 13, help ensure the smooth movement and flexible adjustment of the lifting door 13, and avoid abnormal stagnation due to excessive resistance.

[0080] As Figure 1 shown, the two slide rails 141 are arranged oppositely and are both arranged inside the installation door frame 12.

[0081] In this embodiment, the slide rails 141 are arranged inside the installation door frame 12 to make rational use of space and avoid the slide rails 141 of the lifting guide mechanism 14 occupying the space outside the installation door frame 12 and affecting the arrangement of other devices adjacent to the channel opening and closing device 100.

[0082] Among them, the floating connection mechanism 15 further includes a second mounting portion 152 for connecting with the slider 142. As Figure 3 can be seen, the second mounting portion 152 is connected to the edge of the first mounting portion 151, and their positional relationship is L-shaped. Specifically, in this embodiment, the first mounting portion 151 and the second mounting portion 152 are integral.

[0083] In addition, a strengthening structure 153 is further provided between the first mounting portion 151 and the second mounting portion 152. The installation position of the strengthening structure 153 is as Figure 3As shown, the reinforcing structure 153 is clamped between the second mounting portion 152 and the first mounting portion 151 which are bent structures. The two adjacent side surfaces of the reinforcing structure 153 are respectively perpendicular to the surfaces between the second mounting portion 152 and the first mounting portion 151, and are connected by welding. In other embodiments, a plurality of reinforcing structures 153 may also be provided between the first mounting portion 151 and the second mounting portion 152 to improve the reinforcing ability. In this embodiment, only one reinforcing structure 153 is provided to avoid the influence of the reinforcing structure 153 on the installation of fasteners such as screws.

[0084] In this embodiment, the design of arranging the second mounting portion 152 and the first mounting portion 151 in an L shape to form a bent structure, and the addition of the reinforcing structure 153 contribute to improving the reliability and stability of the connection of each component in the floating connection mechanism 15.

[0085] As Figures 3 - 4 shown, a through hole 1521 is provided on the surface of the second mounting portion 152 facing the mounting door frame 12, that is, the through hole 1521 is arranged through the second mounting portion 152 along the width direction of the mounting door frame 12 for a contact member to pass through and contact the slide rail 141.

[0086] In this embodiment, the design of the through hole 1521 allows the setting of a contact member or other fixing devices to fix the lifting door 13 at a specific position relative to the mounting door frame 12, ensuring a more stable connection between the lifting door 13 and the mounting door frame 12, preventing the lifting door 13 from accidentally loosening or falling off relative to the mounting door frame 12 during bumpy transportation, and improving the safety during transportation and the integrity of the lifting door 13 and the surrounding environment.

[0087] The channel opening and closing device 100 in this embodiment is applied in a battery swapping station to realize the opening and closing of the channel opening 11 of the battery swapping station. However, in other embodiments, the channel opening and closing device 100 can also be applied to other devices in the battery swapping field to achieve the purpose of reliably opening and closing the channel opening 11.

[0088] As Figure 1As shown, the passage opening and closing device 100 also includes a stroke amplification mechanism 16, a driving mechanism 17 and a counterweight mechanism 18. Among them, the counterweight mechanism 18 is used to balance the weight of the lifting door 13, so that the driving mechanism 17 can drive the lifting door 13 to lift and lower through a smaller load. The stroke amplification mechanism 16 is used to realize the transmission between the lifting door 13 and the counterweight mechanism 18 and the driving mechanism 17. The stroke amplification mechanism 16 further includes a first stroke amplification part 161 and a second stroke amplification part 162, which correspond to the driving mechanism 17 and the counterweight mechanism 18 respectively, to amplify the driving stroke, so that the driving mechanism 17 and the counterweight mechanism 18 can drive the lifting door 13 to a larger position through a smaller displacement. Specifically, the driving mechanism 17 is connected to the lifting door 13 through the first stroke amplification part 161, and the counterweight mechanism 18 is connected to the lifting door 13 through the second stroke amplification part 162. Specifically in this embodiment, Figure 1 As shown, the first stroke amplification part 161 and the second stroke amplification part 162 of the stroke amplification mechanism 16 both realize stroke amplification by means of a movable pulley. Due to the stroke amplification feature of the movable pulley, the amplified stroke ratio is 1:2, that is, the driving mechanism 17 produces a displacement of 1, which can drive the lifting door 13 to move a displacement of 2, so that the driving mechanism 17 and the counterweight mechanism 18 can drive the lifting door 13 to move a larger amplitude only by a relatively small movement, so that the driving mechanism 17 and the counterweight mechanism 18 can be set in the installation door frame 12, and will not affect the normal passage at the passage opening 11 due to the large movement amplitude.

[0089] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
