Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle assembly, and particularly relates to a motorcycle wheel hub and tire mounting structure based on laser scanning. Background Art

[0002] The assembly of motorcycle tires and wheel hubs is a key link in the manufacture of the whole vehicle, and the quality of its assembly directly affects the safety, handling performance, comfort and tire life of the vehicle. In the whole vehicle manufacturing workshop, the traditional method of installing tires is to use a pressure device with a certain mechanical structure. First, place the wheel hub at a certain position, then lap the tire on the upper end of the wheel hub, and use the lever principle to operate the pressure device to press the tire onto the outside of the wheel hub.

[0003] The pressing blocks used for pressing the tires in the above-mentioned pressure device are generally symmetrically distributed. After the tires are lapped on the upper end of the wheel hub in a staggered manner, by rotating the pressure device and visually finding a suitable force application position outside the tire, after the two pressing blocks of the pressure device are symmetrically distributed on both sides of the staggered center line of the tire and the wheel hub, the tire can be pressed in manually or mechanically. There are disadvantages such as low operation efficiency and excessive human errors. Summary of the Invention

[0004] The purpose of the present invention is to provide a motorcycle wheel hub and tire mounting structure based on laser scanning. By using the rotational movement of the turntable and the cooperative transmission formed by the tire bottom support assembly and the tire top support assembly, after clamping the wheel hub and the tire, during the process of the turntable rotating to the horizontal position, the purpose of safely releasing the tire to the top of the wheel hub can be achieved. It is not only convenient to place the wheel hub and the tire after tilting the turntable forward, but also can realize the automatic release of the tire during the process of rotating the turntable to the safe water level position.

[0005] The purpose of the present invention is achieved through the following technical solutions. A motorcycle wheel hub and tire mounting structure based on laser scanning includes a chassis body, a turntable assembly, a tire bottom support assembly, a tire top support assembly and an auxiliary clamping column member. The turntable assembly includes a turntable. The tire bottom support assembly includes a corner seat and an incomplete fixed gear. The tire top support assembly includes a passive inclined block. The auxiliary clamping column member includes an auxiliary clamping column.

[0006] The turntable is rotatably connected to the upper end of the frame body of the chassis body. The corner seats are symmetrically slidably connected in the inner frame of the turntable. A bottom support block is fixed to the top end of each group of corner seats. A passive lead screw is rotatably connected horizontally to the bottom end of the inner frame of the turntable, and the symmetrically distributed corner seats are all connected in cooperation with the passive lead screw. The incomplete fixed gear is fixedly connected to one side of the upper inner end of the chassis body. A transmission gear is rotatably connected to the bottom end of the inner frame of the turntable. The transmission gear is in transmission connection with one end of the passive lead screw, and within a certain angular rotation range of the turntable, the transmission gear meshes with the incomplete fixed gear.

[0007] In each set of corner seats, a top support block is also elastically slidably connected towards the bottom support block, a passive inclined block is fixedly connected to one side of the top support block, and fixed inclined blocks are fixedly arranged in pairs on one side of the inner frame of the rotary frame.

[0008] The bottom end of the auxiliary clamping post is elastically rotatably connected to the middle part of the outer side of the rotary frame, and a nylon pushing block is fixedly connected to one side of the top end of the bottom frame body.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] When the rotary frame rotates forward and tilts to a certain position, the wheel hub can be inserted through its central hole and placed in the middle of the inner frame of the rotary frame.

[0011] And when the rotary frame rotates forward and tilts to a certain position, the two sets of corner seats are also in the limit position of approaching each other, and the top support block is in the limit position of approaching the bottom support block. After the wheel hub is installed, the tire can be clamped into the three-point support space formed by the symmetrically distributed top support blocks, bottom support blocks on both sides and the auxiliary clamping posts, and the placed tire and wheel hub are in a non-facing state.

[0012] And when the rotary frame rotates forward and tilts to the position for placing the wheel hub and tire, the transmission gear is in a position where it does not mesh with the incomplete fixed gear. Only when the rotary frame rotates backward and tilts to a certain angle, the transmission gear enters the meshing state with the incomplete fixed gear.

[0013] After the tire and wheel hub are both placed, rotate the rotary frame in the backward tilting direction, so that the rotary frame gradually rotates to the horizontal position. During the process of the rotary frame tilting backward and rotating to the horizontal position, the transmission gear enters the meshing state with the incomplete fixed gear. At this time, as the rotary frame continues to tilt backward and rotate in the horizontal direction, it can drive the freely rotating transmission gear to form a cooperative drive with the fixed incomplete fixed gear, thereby driving the rotation of the passive lead screw. Using the cooperative drive formed by the passive lead screw and the symmetrically distributed corner seats, the two sets of corner seats can be driven to move away from each other, achieving the purpose of gradually releasing the tire.

[0014] And when the two sets of corner seats move away from each other to a certain position, the passive inclined block on one side of the top support block enters the tangential fit with the inclined surface of the fixed inclined block. As the two sets of corner seats continue to move away, the top support block is synchronously driven to overcome its own elastic force and move away from the bottom support block, gradually losing the pressing state on the tire until both the bottom support block and the top support block are separated from the outer surface of the tire.

[0015] Synchronously, and before the rotary frame tilts backward and rotates to the horizontal position, during the process of the bottom support block and the top support block separating from the outer surface of the tire, the auxiliary clamping post will also contact the nylon pushing block, causing the auxiliary clamping post to gradually separate from the outer surface of the tire, so that the tire falls onto the top of the wheel hub due to its own gravity and forms an interlaced state.

[0016] Subsequently, through the continuous backward rotation of the turntable, the turntable rotates to the horizontal position. At this time, a position convenient for installing the tire and wheel hub is formed. The laser scanning device at the top of the chassis can scan the actual contact position state of the tire relative to the wheel hub, facilitating the subsequent installation work;

[0017] After the tire and wheel hub are installed, rotate the turntable forward and tilt to remove the wheel hub and tire.

[0018] By adopting the above technical solutions, the present invention can achieve the following beneficial effects:

[0019] (1) Based on the automatically rotatable turntable, the present invention can form a function of conveniently and safely placing the front wheel hub and tire, and after the turntable rotates to the horizontal position, the purpose of safely installing the tire and wheel hub can be achieved;

[0020] (2) The present invention uses the bottom support block and the top support block with a certain height difference from the rear wheel hub to form the clamping work for the tire to be installed. Cooperating with the auxiliary clamping column elastically screwed to the middle part of the outer side of the turntable, a three-point stable support state for the tire can be formed; and after the turntable rotates backward and tilts to a certain angle, not only the cooperative transmission formed by the transmission gear and the incomplete fixed gear can drive the symmetrically distributed bottom support blocks to move away from each other, but also the tangent fit of the passive inclined block and the fixed inclined block drives the top support block to move away from the bottom support block, so that when the turntable rotates backward and tilts to a safe position, both the top support block and the bottom support block can be separated from the outer surface of the tire. Under the action of the self-gravity of the tire, it can fall to the position staggered with the top of the wheel hub. At this time, the free fall of the tire will not fall to a position outside the wheel hub;

[0021] (3) And in order to realize the free and smooth fall of the tire after the top support block and the bottom support block are separated from the outer surface of the tire, the present invention also provides an elastic touch cooperation formed by the auxiliary clamping column and the nylon pushing block. The elastic rotational force formed by the auxiliary clamping column itself can not only cooperate with the top support block and the bottom support block to support the tire to be installed, but also make the nylon pushing block contact the auxiliary clamping column when the turntable rotates backward and tilts to a safe position, pushing the auxiliary clamping column away from the outer surface of the tire, achieving the purpose of unobstructed free fall of the tire.

[0050] As Figures 1 - 16 shown, a motorcycle wheel hub tire mounting structure based on laser scanning. The turntable 203 in the turntable assembly 2 is rotatably connected to the upper end of the frame body 1 of the chassis, and the turntable 203 can automatically rotate within a certain angle range. The corner seats 303 are symmetrically slidably connected in the inner frame of the turntable 203. A bottom support block 304 is fixed to the top end of each group of corner seats 303. A passive lead screw 305 is rotatably connected transversely to the bottom end of the inner frame of the turntable 203, and the symmetrically distributed corner seats 303 are all connected in cooperation with the passive lead screw 305. When the passive lead screw 305 rotates, it can drive the two groups of corner seats 303 to move towards each other. The incomplete fixed gear 306 is fixedly connected to one side of the upper inner end of the chassis 1. A transmission gear 311 is rotatably connected to the bottom end of the inner frame of the turntable 203. The transmission gear 311 is in transmission connection with one end of the passive lead screw 305, and within a certain angle rotation range of the turntable 203, the transmission gear 311 meshes with the incomplete fixed gear 306, so that with the rotation of the turntable 203, a synchronous opening and closing action of the two groups of corner seats 303 can be formed.

[0051] In each group of corner seats 303, a top support block 402 is also elastically slidably connected towards the bottom support block 304. A passive inclined block 403 is fixedly connected to one side of the top support block 402. A fixed inclined block 404 is fixedly connected in pairs to one side of the inner frame of the turntable 203. When the corner seat 303 moves transversely to a certain position, the passive inclined block 403 can form a mating with the fixed inclined block 404 where the inclined surfaces are tangent to each other, so that when the two groups of corner seats 303 move away from each other, the top support block 402 can synchronously move away from the bottom support block 304.

[0052] The bottom end of the auxiliary clamping post 706 is elastically rotatably connected to the middle of the outer side of the turntable 203. A nylon pushing block 708 is fixedly connected to one side of the top end of the chassis 1. When the turntable 203 rotates backward to a certain position, the outer surface of the top end of the auxiliary clamping post 706 can contact and abut against the nylon pushing block 708.

[0053] The working principle is as follows:

[0054] This device is used for the installation of motorcycle tires and wheel hubs.

[0055] When the turntable 203 tilts forward and rotates to a certain position, a state convenient for the installation of the wheel hub and the tire can be formed. The wheel hub can be inserted through its central hole and placed in the middle of the inner frame of the turntable 203.

[0056] Moreover, when the turntable 203 tilts forward and rotates to a certain position, the two sets of corner seats 303 are also at the limit position of approaching each other, and the top support block 402 is at the limit position of approaching the bottom support block 304. After the wheel hub is installed, the tire can be clamped into the three-point support space formed by the symmetrically distributed top support blocks 402 and bottom support blocks 304 on both sides and the auxiliary clamping posts 706, and the tire clamped between the top support block 402 and the bottom support block 304 is in a compressed state.

[0057] Moreover, the top support block 402, the bottom support block 304, and the auxiliary clamping posts 706 will not interfere with the placement of the wheel hub prior to the tire.

[0058] Moreover, the placed tire and wheel hub are in a non-facing state, aiming to facilitate the subsequent release of the tire, so that the tire overlaps staggeredly at the top of the wheel hub.

[0059] And when the turntable 203 tilts forward and rotates to the position for placing the wheel hub and the tire, the transmission gear 311 is in a non-engaged position with the incomplete fixed gear 306. Only after the turntable 203 rotates backward to a certain angle, the transmission gear 311 enters the engaged state with the incomplete fixed gear 306, aiming to convey the tire to a safe position.

[0060] After the tire and the wheel hub are both placed, rotate the turntable 203 in the backward tilting direction, so that the turntable 203 gradually rotates to the horizontal position. During the process of the turntable 203 tilting backward to the horizontal position, the transmission gear 311 enters the engaged state with the incomplete fixed gear 306. At this time, as the turntable 203 continues to tilt backward and rotate in the horizontal direction, it can drive the transmission gear 311 in the freely rotating state to form a cooperative drive with the fixed incomplete fixed gear 306, thereby driving the rotation of the passive lead screw 305. Using the cooperative drive formed by the passive lead screw 305 and the symmetrically distributed corner seats 303, it can drive the two sets of corner seats 303 to move away from each other, achieving the purpose of gradually releasing the tire.

[0061] And when the two sets of corner seats 303 move away from each other to a certain position, the passive inclined block 403 on one side of the top support block 402 enters the tangential fit with the inclined surface of the fixed inclined block 404. As the two sets of corner seats 303 continue to move away, it synchronously drives the top support block 402 to overcome its own elastic force and move away from the bottom support block 304, gradually losing the compressed state of the tire until both the bottom support block 304 and the top support block 402 are separated from the outside of the tire.

[0062] Synchronously, and before the turntable 203 rotates backward to the horizontal position, during the process of the bottom support block 304 and the top support block 402 separating from the outer surface of the tire, the auxiliary clamping post 706 will also contact the nylon pushing block 708, causing the auxiliary clamping post 706 to gradually separate from the outer surface of the tire, allowing the tire to fall to the top of the wheel hub due to its own gravity and forming an interlaced state;

[0063] Subsequently, through the continuous backward rotation of the turntable 203, the turntable 203 rotates to the horizontal position. At this time, a position convenient for installing the tire wheel hub is formed. The laser scanning device at the top of the chassis body 1 can scan the actual contact position state of the tire relative to the wheel hub, facilitating the subsequent installation work;

[0064] After the tire and the wheel hub are installed, rotate the turntable 203 forward to remove the wheel hub and the tire. Moreover, there is a certain height difference between the bottom support block 304 and the top support block 402 used for clamping the tire and the relevant mechanisms and the installation position of the wheel hub, which will not interfere with the removal of the wheel hub and the tire after installation.

[0065] The specific structure of the turntable assembly 2 is as shown in Figure 2 and Figure 3 The main rotation seats 201 are symmetrically and fixedly installed on both sides of the upper end of the frame of the chassis body 1, and the cylinder body fixed rotation seats 202 are symmetrically and fixedly installed on both sides of the lower end of the frame of the chassis body 1;

[0066] On both sides of the bottom end of the inner frame of the turntable 203, main rotation shafts 204 are horizontally fixed. The main rotation shafts 204 on the same side are rotatably connected in the main rotation seats 201. An outer connection seat 205 is fixed at the outer end of each group of main rotation shafts 204. A moving rotation shaft 206 is horizontally fixed on the other side of the outer end of the outer connection seat 205. The bottom end of the main body of the tilting electric cylinder 207 is rotatably connected to the cylinder body fixed rotation seat 202, and the telescopic rod of the tilting electric cylinder 207 is rotatably connected to the moving rotation shaft 206;

[0067] By synchronously starting the two groups of tilting electric cylinders 207, the movement of the telescopic rods of the tilting electric cylinders 207, and the combined drive formed by the telescopic rods of the tilting electric cylinders 207 and the moving rotation shafts 206, the outer connection seats 205, the main rotation shafts 204, and the turntable 203 can be driven to form a rotation action with the main rotation seats 201 as the reference, achieving the purpose of the forward and backward rotation actions of the turntable 203;

[0068] A wheel hub mounting seat 208 is fixedly installed in the middle of the top end of the inner frame of the turntable 203. During the installation of the wheel hub, the wheel hub mounting seat 208 can be inserted into the central hole of the wheel hub;

[0069] And during the installation process of the tire and the wheel hub, the wheel hub is allowed to rotate with the mounting seat 208 as the reference, without causing adverse effects on the process of pressing the tire into the wheel hub.

[0070] The specific structures of the tire bottom support assembly 3 and the tire top support assembly 4 are as follows Figure 4 , Figure 5 , Figure 6 and Figure 7 shown. The chute 301 is symmetrically arranged in the inner frame body of the rotating frame 203. The inner slider 302 is fixedly connected to the bottom end of the corner seat 303, and the inner sliders 302 on the same side are slidably connected in the chute 301;

[0071] Both sides of the bottom end of the inner frame of the rotating frame 203 are fixedly connected with lead screw rotating seats 307. The two ends of the passive lead screw 305 are respectively rotatably connected to different lead screw rotating seats 307. A lead screw slider 308 is fixedly installed at the bottom end of each group of inner sliders 302, and the lead screw slider 308 is in cooperative connection with the passive lead screw 305;

[0072] By setting the part of the passive lead screw 305 cooperating with the two groups of lead screw sliders 308 to rotate left or right, a state where a single passive lead screw 305 drives the two groups of lead screw sliders 308 to move towards each other can be formed. This is the prior art and will not be elaborated here;

[0073] A transmission shaft 310 is horizontally installed and fixed on one side of the bottom end of the inner frame of the rotating frame 203. The transmission gear 311 is rotatably connected to the transmission shaft 310. One end of the passive lead screw 305 is fixed with a lead screw gear 309, and the lead screw gear 309 is meshed with the transmission gear 311;

[0074] After the transmission gear 311 enters the position where it cooperates with the incomplete fixed gear 306, the rotation of the rotating frame 203 can drive the transmission gear 311 to form a cooperative transmission with the lead screw gear 309, achieving the purpose of driving the passive lead screw 305 to rotate synchronously through the rotation of the rotating frame 203. Utilizing the cooperative transmission formed by the rotation of the passive lead screw 305 and the lead screw slider 308, the two symmetrically distributed corner seats 303 can be driven to move towards each other;

[0075] Pairs of sliding columns 405 are fixedly connected between the passive inclined blocks 403 and the sliding frame 401 on the same side. The sliding columns 405 are slidably connected to the main body of the corner seat 303. The top support block 402 is fixedly connected to the bottom end of the sliding frame 401. A compression spring 406 is sleeved and installed in each group of sliding columns 405. One end of the compression spring 406 is fixedly clamped with the passive inclined block 403, and the other end is fixedly clamped with the corner seat 303;

[0076] Under the action of the supporting elastic force of the compression spring 406 on the passive inclined block 403 relative to the corner seat 303, a state where the top support block 402 elastically approaches the bottom support block 304 can be formed, such that when there is no external force pushing the passive inclined block 403, the top support block 402 is in the position where it is clamped to the outer surface of the tire after being combined with the bottom support block 304.

[0077] The specific structure of the auxiliary clamping column member 7 is as follows Figure 13, Figure 14 and Figure 15 As shown in Figure 14 and Figure 15 , the elastic fixed rotating seat 701 is fixedly connected to the middle part of the outer side of the rotating frame 203. The elastic rotating seat 702 is rotatably connected to the elastic fixed rotating seat 701. A clamping seat 703 is fixedly installed at the bottom end of the outer side of the frame body of the rotating frame 203. An elastic connecting piece 704 is clamped and installed between the clamping seat 703 and the elastic rotating seat 702;

[0078] A flat support 705 is fixedly installed at the top end of the elastic rotating seat 702. The auxiliary clamping column 706 is installed and fixed at one side of the top end of the flat support 705;

[0079] The elastic connecting piece 704 clamped between the clamping seat 703 and the elastic rotating seat 702 can form a supporting elastic force for the rotation of the elastic rotating seat 702, so that when the auxiliary clamping column 706 is not pushed by an external force, the auxiliary clamping column 706 is in a position to support the outer side of the tire;

[0080] One end of the top arm 707 is fixedly connected to the middle part of the top side of the top frame 501, and the other end is fixedly connected to the nylon pushing block 708, and the top arm 707 and the nylon pushing block 708 will not interfere with the clamping of the wheel hub and the tire and the removal of the tire after it is installed on the wheel hub.

[0081] As Figure 8 , Figure 9 and Figure 10 As shown in Figure 8 , Figure 9 and Figure 10 , a pressing and clamping assembly 5 is further installed at the top end of the chassis body 1 to realize the installation work of the tire and the wheel hub after the rotating frame 203 rotates to the horizontal state. A pair of top frames 501 are fixedly connected to the top end of the chassis body 1. A top fixing plate 502 is fixed between the inner top ends of the top frames 501. A pressing and clamping sliding seat 503 is arranged and fixed in the main body of the top fixing plate 502. A pressing and clamping sliding column 505 is slidably connected to the pressing and clamping sliding seat 503. A top connecting plate 504 is fixedly connected to the top end of the pressing and clamping sliding column 505. A pressing and clamping pushing plate 507 is fixedly connected to the bottom end of the pressing and clamping sliding column 505;

[0082] A pressing and clamping hydraulic cylinder 506 is installed and fixed in the middle of the top end of the top fixing plate 502. The top end of the telescopic rod of the pressing and clamping hydraulic cylinder 506 is fixedly connected to the top connecting plate 504;

[0083] A middle fixed rotating seat 508 is installed and fixed in the middle of the main body of the pressing and clamping pushing plate 507. The top middle part of the rotating seat 509 is fixedly connected with an adjusting rotating shaft 511. A thrust bearing 515 is sleeved and installed at the bottom end outside the adjusting rotating shaft 511. The adjusting rotating shaft 511 is rotatably connected to the middle fixed rotating seat 508. The top end of the thrust bearing 515 is in contact with the bottom surface of the pressing and clamping pushing plate 507, which can improve the supporting strength of the pressing and clamping pushing plate 507 for the downward movement of the rotating seat 509;

[0084] By starting the clamping hydraulic cylinder 506, the movement of the telescopic rod of the clamping hydraulic cylinder 506 can drive the component formed by the connection of the top connecting plate 504 and the clamping pushing plate 507 to move guided by the sliding fit formed by the clamping sliding column 505 and the clamping sliding seat 503;

[0085] The top end of the adjusting rotating shaft 511 is fixed with an adjusting gear 512. The top end of the clamping pushing plate 507 is installed and fixed with a servo motor 513. A driving gear 514 is fixed in the rotating shaft of the servo motor 513. The driving gear 514 meshes with the adjusting gear 512;

[0086] The bottom end of the rotating seat 509 is fixedly provided with clamping blocks 510 in pairs;

[0087] By starting the servo motor 513 to drive the cooperative transmission formed by the driving gear 514 and the adjusting gear 512, the rotating seat 509 and the clamping blocks 510 can be driven to rotate with the middle fixed rotating seat 508 as the reference. The purpose of the rotation of the clamping blocks 510 is to rotate the two groups of clamping blocks 510 to a position suitable for pushing the tire downward according to the actual position of the tire falling relative to the wheel hub in the horizontal position state of the rotating frame 203;

[0088] That is, the two groups of clamping blocks 510 are rotated and adjusted to the positions evenly divided on both sides of the staggered position of the tire and the wheel hub, so that the tire can be subjected to the uniform downward pressure of the two groups of clamping blocks 510;

[0089] After the two groups of clamping blocks 510 contact the top end of the tire, with the force exerted by the clamping blocks 510 formed by the downward movement of the clamping pushing plate 507, the tire can be first driven to snap onto the outside of the wheel hub on one side, and then the other side of the tire can be snapped onto the outside of the wheel hub;

[0090] It should be noted that since the transmission ratio formed by the cooperation of the rotating frame 203 with the bottom supporting block 304 and the top supporting block 402 remains unchanged during the rotation adjustment, and the distance between the two groups of clamping blocks 510 also remains unchanged, this device is only applicable to the installation operation of a certain specification size of tire and wheel hub.

[0091] As Figure 16 shown, a laser scanning module 8 is also installed in the rotating seat 509. During the operation, the relative position of the tire and the wheel hub can be scanned. Installation plates 801 are fixed on both sides of the middle part of the outer end of the rotating seat 509. The laser scanning probe 802 is installed and fixed on the outer end of the installation plate 801;

[0092] When the rotating seat 509 and the clamping blocks 510 rotate, by using the rotation action of the laser scanning probe 802, the relative position of the tire and the wheel hub can be scanned in real time;

[0093] The laser scanning probe 802 can scan the initial state when the tire falls into contact with the wheel hub, so as to guide the initial contact positions of the two groups of clamping blocks 510 with the outer surface of the tire, and improve the success rate of pushing one side of the tire by the clamping blocks 510 to be clamped outside the wheel hub.

[0094] Preferably, as Figure 11 and 12 shown, an insertion and fixation member 6 is also installed between the clamping and pushing plate 507 and the rotating frame 203, which can improve the safety and stability during the process of pressing the tire by the clamping blocks 510. The insertion post connecting frames 602 are symmetrically and fixedly connected to both ends of the clamping and pushing plate 507. At both ends of each group of insertion post connecting frames 602, insertion posts 603 are vertically fixed. On both sides of the top end of the rotating frame 203, follower fixing sleeves 601 are fixedly arranged in pairs; and after the rotating frame 203 rotates backward to the horizontal position, the position of the follower fixing sleeve 601 is just opposite to the insertion post 603. When the clamping and pushing plate 507 moves down to a certain position, that is, when the bottom end of the clamping block 510 contacts the outer surface of the tire, the insertion post 603 can just be inserted into the follower fixing sleeve 601, so as to enable the rotating frame 203 to stably maintain the horizontal state during the process of clamping the tire outside the wheel hub by the downward-moving clamping block 510, and at the same time, it can also protect the mechanism that drives the rotation of the rotating frame 203 when the clamping block 510 moves down and applies force.

[0095] 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 it; 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 recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
