Description

Technical Field

[0001] This invention relates to the field of children's products, and more specifically to a carrier and a stroller having the carrier. Background Technology

[0002] Currently, some carriers for infants and toddlers on the market, such as baby bassinets, typically have a space for the infant to lie down, with a fabric cover around the perimeter of the space to protect the infant. For ease of daily storage and carrying, these carriers are usually designed with a foldable structure. In existing technology, carriers typically include features that can be folded along their length to reduce volume. However, in carriers disclosed in patent documents such as CN207949456U, CN205548140U, CN204708434U, and CN203693076U, although the carrier can be folded along its length, the fabric cover inside the space is usually exposed after folding. During daily carrying and storage, the fabric cover is easily soiled, affecting the carrier's next use. Summary of the Invention

[0003] The purpose of this invention is to provide a new vehicle to solve one or more problems of the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a carrier having a folded state and an extended state, the carrier including a first connecting structure and a second connecting structure, and the carrier further including:

[0005] Two first support structures, each of which is connected to the first associated structure, and each of the first support structures is rotatable relative to the first associated structure;

[0006] Two second support structures, each of which is connected to the second associated structure, and each of the second support structures is rotatable relative to the other.

[0007] A linkage structure is provided between the first support structure and the second support structure, and is movable relative to at least one of the first support structure and the second support structure;

[0008] An actuation mechanism, coupled to the first and second associated structures, locks the first and second associated structures when the vehicle is in an extended state to position the relative positions of the first and second support structures. When the vehicle moves from an extended state to a folded state, the actuation mechanism unlocks the first and second associated structures to allow the first and second support structures to rotate relative to each other, and the first and second support structures, as well as the linkage structure, retract inward.

[0009] Preferably, the actuating mechanism includes:

[0010] The first actuating structure is adjacent to the first associated structure;

[0011] The second actuating structure is adjacent to the second associated structure;

[0012] A connection structure that connects the second associated structure and the first actuating structure respectively;

[0013] When the vehicle moves from the extended state to the folded state, the second actuating structure unlocks the second associated structure to allow each of the second support structures to rotate relative to each other, and via the connecting structure drives the first actuating structure to unlock the first associated structure to allow each of the first support structures to rotate relative to each other.

[0014] Furthermore, the second association structure includes:

[0015] A first joint member is connected to one of the second support structures, and the first joint member is slidably connected to the second actuating structure.

[0016] The second joint is connected to another second support structure. The second joint and the first joint are coaxially disposed on the first axis and can rotate relative to the first axis.

[0017] When the vehicle moves from an extended state to a folded state, the second actuating structure slides relative to the first joint to unlock the second associated structure, causing the first joint to rotate around the first axis in a first direction, which in turn drives the second joint to rotate around the first axis in a second direction, wherein the first direction is opposite to the second direction.

[0018] In some embodiments, the actuation mechanism further includes an actuator connected to the second actuation structure, which, when subjected to an actuating force, causes the second actuation structure to slide relative to the first joint.

[0019] In some embodiments, the second actuating structure is provided with a locking block, and the first joint and the second joint are respectively provided with a first groove and a second groove; when the second associated structure is locked, the locking block is inserted into the second groove, and when the second associated structure is unlocked, the locking block is disengaged from the second groove.

[0020] In some embodiments, the connecting structure is rotatably connected to the second joint member. When the second joint member rotates in the second direction, the connecting structure rotates relative to the second joint member, causing the connecting structure to drive the first actuating structure to unlock the first associated structure.

[0021] In some embodiments, the first joint member and the second joint member are respectively provided with an eccentrically arranged and axially non-overlapping first and second sliding grooves. The connecting structure is provided with a first sliding member that can slide along a third direction. The first sliding member is provided with a first protrusion that can be inserted into the first and second sliding grooves and can slide along the first and second sliding grooves. When the first joint member rotates along the first direction, the first sliding groove rotates accordingly, so as to drive the first protrusion to slide relative to the first and second sliding grooves respectively, thereby causing the first sliding member to slide along the third direction, and causing the second joint member to rotate along the second direction.

[0022] In some embodiments, the connection structure includes a sliding sleeve, the first sliding member is slidably disposed on the sliding sleeve, the sliding sleeve is coaxially disposed on the first axis with the first joint member and the second joint member, and is rotatable relative to the first axis; when the carrier enters the folded state from the extended state, the first joint member and the second joint member rotate toward the sliding sleeve to retract.

[0023] In some embodiments, the connection structure further includes:

[0024] The sliding sleeve is provided with a third sliding groove;

[0025] A slide rod that can slide within the slide sleeve, the slide rod having a second protrusion that can slide within the third slide groove;

[0026] The second joint is also provided with an eccentrically arranged third groove that cooperates with the second protrusion; when the second joint rotates, the third groove drives the second protrusion to slide in the third groove.

[0027] In some embodiments, the first actuating structure includes:

[0028] The first inclined structure is provided on the slide rod;

[0029] A second inclined structure is provided on the latch, and the second inclined structure cooperates with the first inclined structure;

[0030] The slide sleeve is provided with a locking groove that matches the latch;

[0031] The first connecting structure includes a first connector and a third joint and a fourth joint respectively connected to each of the first support structures. The first connector has a channel for the sliding sleeve to slide therein. The first connector, the third joint and the fourth joint are coaxially arranged on a second axis, and the third joint and the fourth joint can rotate relative to each other about the second axis.

[0032] When the slide rod slides in the sliding sleeve, the first inclined structure applies a force to the second inclined structure to move the second inclined structure, thereby unlocking the latch and causing the first connector to slide on the sliding sleeve toward the second associated structure, thereby causing the third joint and the fourth joint to rotate relative to each other.

[0033] In some embodiments, the carrier further includes a limiting member disposed at the top of the slide bar to restrict upward movement of the slide bar.

[0034] In some embodiments, the second associated structure is provided with a first engagement member that is adapted to an external bracket to engage the carrier to the external bracket or to detach the carrier from the external bracket.

[0035] When the vehicle is engaged with the external bracket and the vehicle is in an extended state, the horizontal plane at the bottom of the vehicle formed by each of the second support structures is more than 40 cm away from the bottom of the external bracket.

[0036] In some embodiments, when the vehicle is in an extended state, each of the first support structures, the linkage structure, and each of the second support structures extends to form a receiving space and forms a symmetrically arranged dihedral on the side of the vehicle.

[0037] In some embodiments, the carrier further includes a grip having a second connector rotatably mounted on a second shaft.

[0038] Another object of the present invention is to provide a stroller having the above-described carrier.

[0039] To achieve the above objectives, the technical solution adopted by the present invention is: a children's stroller, the children's stroller comprising:

[0040] The vehicle as described above, wherein the second associated structure is provided with a first coupling member;

[0041] An external support is provided with a second engagement member adapted to the first engagement member, the first engagement member engaging with the second engagement member to assemble the vehicle onto the external support.

[0042] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: In the process of the carrier provided by the present invention moving from the extended state to the folded state, each of the first support structures, each of the second support structures and the linkage structure retract inward, so that the cloth cover provided in the carrier's accommodating space is retracted to the inside and will not be exposed to the outside and get dirty.

[0084] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.

[0085] See Figures 1 to 15 The vehicle shown is a folded state and an extended state. The vehicle includes a first connecting structure 3 and a second connecting structure 4. The vehicle also includes:

[0086] Two first support structures 1, each first support structure 1 is connected to a first associated structure 3, and each first support structure 1 can rotate relative to the other.

[0087] Two second support structures 2, each of which is connected to a second associated structure 4, and each of the second support structures 2 can rotate relative to each other;

[0088] Linkage structure 5, which is disposed between the first support structure 1 and the second support structure 2, and can move relative to at least one of the first support structure 1 and the second support structure 2;

[0089] The actuating structure 6 is coupled to the first associated structure 3 and the second associated structure 4. When the vehicle is in the extended state, the actuating structure 6 locks the first associated structure 3 and the second associated structure 4 to position the relative positions of each first support structure 1 and the second support structure 2. When the vehicle moves from the extended state to the folded state, the actuating structure 6 unlocks the first associated structure 3 and the second associated structure 4 so that each first support structure 1 and the second support structure 2 rotates relative to each other, and each first support structure 1, each second support structure 2 and the linkage structure 5 retract inward.

[0090] When the vehicle is in its extended state, each of the first support structures 1, the linkage structure 5, and the second support structures 2 extends to form a accommodating space, creating a symmetrically arranged quadrilateral on the side of the vehicle. This provides the vehicle with good stability and load-bearing capacity in its extended state. Simultaneously, the relative movement of the parts forming this quadrilateral facilitates folding the vehicle, allowing for easy transition between the extended and folded states. A fabric cover is installed inside the accommodating space. When the vehicle is in its folded state, the first support structures 1, the second support structures 2, and the linkage structure 5 retract inwards, concealing the fabric cover and preventing it from being exposed and easily soiled.

[0091] See Figures 1 to 15 As shown, in this embodiment, the front, back, left, right, up, and down directions observed by the infant or toddler inside the vehicle in its extended state are used as a reference. The positions of the vehicle are schematically marked as follows: Figure 1 As shown in the diagram, the detailed structure of the vehicle will be described below in conjunction with this orientation.

[0092] In its extended state, the vehicle has a first support structure 1, a first associated structure 3, and another first support structure 1 arranged sequentially in the front-to-back direction; a second support structure 2, a second associated structure 4, and another second support structure 2 arranged sequentially in the front-to-back direction, with the two first support structures 1 located above the two second support structures 2, and the first associated structure 3 located above the second associated structure 4.

[0093] Each first support structure 1 is a U-shaped rod, comprising two first support rods 11 located on the left and right sides and extending in the front-back direction, and a first crossbar 12 fixed between one end of the two first support rods 11. Each second support structure 2 is also a U-shaped rod, comprising two second support rods 21 located on the left and right sides and extending in the front-back direction, and a second crossbar 22 fixed between one end of the two second support rods 21. The first connecting structure 3, the second connecting structure 4, and the actuating structure 6 each have two sets located on the left and right sides. On each side of the vehicle, the other ends of the two first support rods 11 are connected by the first connecting structure 3, and the other ends of the two second support rods 21 are connected by the second connecting structure 4. The actuating structure 6 is located between the first connecting structure 3 and the second connecting structure 4.

[0094] The linkage structure 5 includes multiple linkage rods 51. There are four linkage rods 51 on the left and right sides of the vehicle. A linkage rod 51 is rotatably connected between the first support rod 11 and the second support rod 21 at the corresponding positions. Specifically, the upper part of the linkage rod 51 is pivotally connected to the first support rod 11, and the lower part of the linkage rod 51 is pivotally connected to the second support rod 21. In the front-back direction, the distance between the upper part of the linkage rod 51 and the first associated structure 3 is greater than the distance between the lower part of the linkage rod 51 and the second associated structure 4.

[0095] Referring to the accompanying drawings, the actuation structure 6 includes a first actuation structure, a second actuation structure 62, and a connecting structure 63. The first actuation structure is adjacent to the first associated structure 3, the second actuation structure 62 is adjacent to the second associated structure 4, and the connecting structure 63 connects the second associated structure 4 and the first actuation structure. When the vehicle moves from an extended state to a folded state, the second actuation structure 62 unlocks the second associated structure 4, causing each second support structure 2 to rotate relative to the other. Furthermore, the connecting structure 63 causes the first actuation structure to unlock the first associated structure 3, causing each first support structure 1 to rotate relative to the other.

[0096] Specifically, see Figures 3 to 11 As shown, the second linkage structure 4 includes a first joint 41 and a second joint 42. The first joint 41 is connected to one of the second support structures 2 and is slidably connected to the second actuating structure 62. The second joint 42 is connected to another second support structure 2 and is coaxially disposed on the first axis 101 with the first joint 41, and can rotate relative to the first axis 101. When the vehicle moves from an extended state to a folded state, the second actuating structure 62 slides relative to the first joint 41 to unlock the second linkage structure 4, causing the first joint 41 to rotate around the first axis 101 in a first direction, thereby driving the second joint 42 to rotate around the first axis 101 in a second direction, wherein the first direction and the second direction are opposite. Figure 9From this perspective, the first direction is clockwise and the second direction is counterclockwise.

[0097] In this embodiment, the second actuating structure 62 is generally in the shape of a slider, and is slidably disposed on the first joint member 41 along an axial direction perpendicular to the first axis 101. The second actuating structure 62 is provided with a locking block 621. The first joint member 41 is provided with a first groove 411, and the second joint member 42 is provided with a second groove 421. The second joint member 42 is also provided with a first arc-shaped guide groove 424 communicating with the second groove 421. The first arc-shaped guide groove 424 is located radially inside the second groove 421. The locking block 621 passes through the first groove 411 and is inserted into the second groove 421 or the first arc-shaped guide groove 424. When the second associated structure 4 is locked, the locking block 621 is inserted into the second groove 421; when the second associated structure 4 is unlocked, the locking block 621 disengages from the second groove 421 and enters the first arc-shaped guide groove 424, and can slide relative to each other along the first arc-shaped guide groove 424, so that the first joint member 41 and the second joint member 42 can rotate around the first axis 101.

[0098] The actuating mechanism 6 also includes an actuator 64, which is connected to the second actuating structure 62. When the actuator 64 is subjected to an actuating force, the actuator 64 causes the second actuating structure 62 to slide relative to the first joint 41. Here, the actuator 64 is disposed on the second support structure 2 connected to the first joint 41, and is connected to the second actuating structure 62 by a traction cable (not shown in the figure), which is disposed in the rod cavity of the second support structure 2.

[0099] The connecting structure 63 is rotatably connected to the second joint 42. When the second joint 42 rotates in the second direction, the second joint 42 rotates relative to the connecting structure 61, so that the connecting structure 63 drives the first actuating structure to unlock the first associated structure 3.

[0100] See Figure 8 , Figure 10 As shown, the first joint member 41 and the second joint member 42 are respectively provided with an eccentrically arranged first sliding groove 412 and a second sliding groove 422 that do not coincide axially. The connecting structure 63 is provided with a first sliding member 631 that can slide along a third direction. The first sliding member 631 is provided with a first protrusion 6311 that can be inserted into the first sliding groove 412 and the second sliding groove 422 and can slide along the first sliding groove 412 and the second sliding groove 422. When the first joint member 41 rotates along the first direction, the first sliding groove 412 rotates accordingly, so as to drive the first protrusion 6311 to slide relative to the first sliding groove 412 and the second sliding groove 422 respectively, so that the first sliding member 631 slides along the third direction, thereby causing the second joint member 42 to rotate along the second direction, so that the first joint member 41 and the second joint member 42 rotate and retract toward the connecting structure 63 respectively. The third direction is perpendicular to the axial direction of the first axis 101.

[0101] The connecting structure 63 also includes a sliding sleeve, on which a first sliding member 631 is slidably disposed. The sliding sleeve is coaxially disposed on the first shaft 101 with the first joint member 41 and the second joint member 42 and can rotate relative to the first shaft 101. When the carrier moves from the extended state to the folded state, the first joint member 41 and the second joint member 42 rotate toward the sliding sleeve and retract.

[0102] In this embodiment, see Figures 3 to 11 As shown, the sliding sleeve includes a sliding sleeve body 632 and a sliding sleeve seat 634. The sliding sleeve seat 634 is articulated and is disposed on the first shaft 101. The sliding sleeve seat 634 is locked and unlocked relative to the first joint member 41 and the second joint member 42 by the second actuation structure 62.

[0103] Here, the sliding sleeve seat 634 includes a seat body 634a and a connecting piece 634b. A fifth sliding groove 6343 is provided on the seat body 634a. The main body of the first sliding member 631 is slidably disposed in the fifth sliding groove 6343. The connecting piece 634b restricts the first sliding member 631 axially in the fifth sliding groove 6343. A fourth sliding groove 6342 is provided on the connecting piece 634b. The first protrusion 6311 passes through the fourth sliding groove 6342 on the connecting piece 634b and is inserted into the first sliding groove 412 and the second sliding groove 422.

[0104] The connecting piece 634b is also provided with a fourth groove 6341 and a second arc-shaped guide groove 6344. The fourth groove 6341 is located radially outside the second arc-shaped guide groove 6344 and the two are connected to each other. When the second linkage structure 4 is locked, the locking block 621 is also inserted in the fourth groove 6341; when the second linkage structure 4 is unlocked, the locking block 621 disengages from the fourth groove 6341 and enters the second arc-shaped guide groove 6344, and can slide relative to each other along the second arc-shaped guide groove 6344, so that the first joint member 41, the second joint member 42 and the sliding sleeve seat 434 can rotate relative to each other around the first axis 101.

[0105] The sliding sleeve body 632 is rod-shaped and extends vertically. It is fixedly mounted on the sliding sleeve seat 634 and has a third sliding groove 6321 extending vertically. The connecting structure 63 also includes a sliding rod 633, which also extends vertically and is located within the sliding sleeve body 632, allowing it to slide vertically within the body. The sliding rod 633 has a second protrusion 6331 that can slide within the third sliding groove 6321. The second joint member 42 also has a third groove 423 that mates with and is eccentrically positioned relative to the second protrusion 6331. When the second joint member 42 rotates relative to the sliding sleeve, the third groove 423 causes the second protrusion 6331 to slide within the third sliding groove 6321, thereby causing the sliding rod 633 to slide vertically accordingly, thus driving the first actuating structure to unlock the first associated structure 3.

[0106] Here, to facilitate the processing of the second joint 42, the second joint 42 includes a first part 42a and a second part 42b. The first part 42a is connected to the second support structure 2, and the second part 42b is a disc-shaped iron sheet. The two are fixed to each other to form the second joint 42. The first part 42a and the second part 42b are both provided with a second groove 421, a first arc-shaped guide groove 424, and a second sliding groove 422. Only the second part 42b is provided with a third groove 423. The third groove 423 includes two sections connected along the length direction. One section is an arc-shaped groove with the first shaft 101 as the center of rotation, and the other section is an eccentrically set groove. When the second protrusion 6331 slides in the eccentric groove, it will drive the slide rod 633 to move up and down, thereby unlocking the first linkage structure 3. When the second protrusion 6331 slides in the arc-shaped groove, the second protrusion 6331 provides guidance for the slide rod 633 to rotate relative to the first joint 41 and the second joint 43.

[0107] In this embodiment, the connecting structure 63 further includes a latch 61, which is slidably disposed in the sliding sleeve body 632, and its sliding direction is perpendicular to the sliding direction of the sliding rod 633. The first actuating structure includes a first inclined structure 6332 and a second inclined structure 612. The first inclined structure 6332 is disposed on the sliding rod 633, specifically on the upper part of the sliding rod 633; ​​the second inclined structure 612 is disposed on the latch 612. The first inclined structure 6332 and the second inclined structure 612 cooperate with each other, and the two can be specifically configured as inclined grooves or protrusions with inclined surfaces that can cooperate with each other.

[0108] The sliding sleeve body 632 is also provided with a locking groove 6322 that matches the latch 631. The latch 61 is provided with a locking pin 611 that can be inserted into the locking groove 6322. The locking pin 611 is slidably inserted into the locking groove 6322. The first association structure 3 includes a first connector 33, and a third joint 31 and a fourth joint 32 that are respectively connected to each of the first support structures 1. The first connector 33 is provided with a channel 331 for the sliding sleeve body 632 of the sliding sleeve to slide therein. The first connector 33, the third joint 31 and the fourth joint 32 are coaxially arranged on the second axis 102, and the third joint 31 and the fourth joint 32 can rotate relative to each other around the second axis 102. The first connector 33 is also provided with a locking groove (not shown in the figure) into which the locking pin 611 can be inserted. When the locking pin 611 is inserted into the locking groove, the latch 61 is locked, thereby fixing the first connector 33 relative to the sliding sleeve body 632, and the first association structure 3 is also locked.

[0109] When the slide rod 633 slides in the slide body 632, the first inclined structure 6332 applies a force to the second inclined structure 612 to move the second inclined structure 612, thereby unlocking the latch 61, so that the first connecting member 33 can slide on the slide body 632 of the slide sleeve towards the second associated structure 4, thereby causing the third joint member 31 and the fourth joint member 32 to rotate relative to each other.

[0110] The carrier also includes a limiting member 9, which is located at the top of the slide rod 633 to restrict the slide rod 633 from moving upward. Specifically, the limiting member 9 has a rod portion 91 that can be inserted into the rod cavity of the slide body 632, and a head 92 located at the top of the rod portion 91. The outer diameter of the head 92 is larger than that of the rod portion 91 to prevent it from sliding downward into the rod cavity of the slide body 632. The shape of the channel 331 of the first connecting member 33 is consistent with the shape of the head 92. When the carrier is in the extended state, the head 92 is correspondingly inserted into the channel 331.

[0111] The vehicle also includes a grip 8, on which a second connector 81 is provided. The second connector 81 is rotatably mounted on the second shaft 102. The second connector 81 can be configured to be locked relative to the first associated structure 3, so that it can remain extended in the vertical direction when the vehicle is in the extended state, making it convenient for the user to lift the vehicle through the grip 8.

[0112] The second connecting structure 4 is also provided with a first connecting member 7, which is adapted to the external support 200 so that the carrier can be connected to the external support 200 or the carrier 100 can be detached from the external support 200. In this embodiment, the first connecting member 7 is fixed on the side of the first joint member 41 opposite to the second joint member 42.

[0113] See Figure 1 , Figure 2 As shown, the vehicle is in an extended state, wherein the two first support structures 1 extend relative to the first associated structure 3 in a front-to-back direction, and the two second support structures 2 are located below the first support structures 1 and extend relative to the second associated structure 4 in a front-to-back direction. The linkage rods 51 of the linkage structure 5 are supported between the corresponding first support rods 11 and second support rods 21 on the left and right sides. The first actuation structure and the second actuation structure 62 in the actuation structure 6 lock the first associated structure 3 and the second associated structure 4 respectively. The first support structure 1, the second support structure 2, and the linkage structure 5 form a space for infants to lie down. The user can lift the vehicle by lifting the grip 8.

[0114] When the vehicle needs to be folded, the operator operates actuator 64, which causes the second actuating structure 62 to slide relative to the first joint 41. This unlocks the first joint 41, the second joint 42, and the sliding sleeve seat 634, allowing them to rotate relative to each other around the first axis 101. Subsequently, the first joint 41 is driven to rotate in the first direction, causing the second support structure 2 connected to the first joint 41 to rotate toward the sliding sleeve body 633. The second joint 42 is then rotated in the second direction, causing the second support structure 2 connected to the second joint 42 to also rotate toward the sliding sleeve body 633. During this process, the second protrusion 6331 slides in the third sliding groove 6321, causing the slide rod 633 to slide downwards accordingly. The first inclined structure 6332 on the upper part of the slide rod 633 acts on the second inclined structure 612 on the latch 61, causing the latch 61 to slide, thereby unlocking the first associated structure 3.

[0115] The applied force continues to drive the second support structure 2, connected to the first joint 41, to rotate in the first direction. Under the action of the linkage structure 5, the first support structure 1 is linked and rotates relative to the first associated structure 3, causing the first associated structure 3 to slide downward along the sliding sleeve body 633, so that the two first support structures 1 are relatively closed inside the two second support structures 2, as shown. Figures 12 to 13 As shown.

[0116] Vehicles in folded state, such as Figure 14 , Figure 15 As shown, the first associated structure 3 and the second associated structure 4 approach each other in the vertical direction, and the second support structure 2, the first support structure 1, the sliding body 633, the other first support structure 1, and the other second support structure 2 are sequentially closed. After being folded, the structure is compact and the appearance is flat. The cloth cover set in the accommodating space is stored inside and will not be exposed.

[0117] like Figures 16 to 21As shown, a stroller with a carrier 100 as described above is provided. The outer support 200 of the stroller is a stroller frame. The outer support 200 is provided with a second connecting member 201 that is adapted to the first connecting member 7. By connecting the first connecting member 7 and the second connecting member 201, the carrier 100 can be installed on the outer support 200.

[0118] like Figure 16 , Figure 17 As shown, the vehicle 100 is mounted on the external bracket 200 and is in the extended state. The distance H between the bottom of the vehicle formed by each second support structure 2 and the bottom of the external bracket 200 is greater than 40cm, so that the vehicle 100 is not too close to the ground, reducing dust from the ground and facilitating communication between the person pushing the cart and the person riding it.

[0119] When it is necessary to fold up the stroller, such as Figure 18 , Figure 19 As shown, first, the vehicle 100 is switched to a folded state and retracted with the front rod of the external support 200. Then, the external support 200 is folded down, so that the vehicle 100 is folded into the front of the folded external support 200, as shown. Figure 20 , Figure 21 As shown.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
