In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application.

[0039] In the following description, numerous specific details are set forth to provide a thorough understanding of the application. One skilled in the relevant art will recognize, however, that the application can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail in order to avoid obscuring aspects of the application.

[0040] Referring to FIGS. 1-3, the embodiment provides a golf artificial putting green, which includes an artificial terrain layer 100, a turf layer 200, and an inflating device 300. The turf layer 200 is arranged above the artificial terrain layer 100. The inflating device 300 is used to inflate or deflate the air bags in the artificial terrain layer 100, so as to change the surface formation of the artificial terrain layer 100 and construct a variable slope shape.

[0041] The turf layer 200

[0042] In an embodiment, the turf layer 200 can be a woven artificial turf or an injection-molded artificial turf, for example. The turf layer 200 can be directly laid on the upper surface of the artificial terrain layer 100, or be fixed to the artificial terrain layer 100 by adhesive or the like.

[0043] The artificial terrain layer 100

[0044] The artificial terrain layer 100 includes an air bag group 10 and an adjusting layer 20 arranged on the upper surface of the air bag group 10. The air bag group 10 includes at least two air bags 11 independent of each other.

[0045] In an embodiment, the adjusting layer 20 includes a plurality of adjusting plates 21 laid on the air bag group 10. Adjacent two adjusting plates 21 are separated from each other or are arranged to be foldable. Specifically, the adjusting plates 21 can be independent structures, and a plurality of adjusting plates 21 are arranged in sequence on the upper surface of the air bag group 10 along the length direction of the air bag group 10. Alternatively, the adjusting plates 21 can be connected by hinges or creases, and the two adjusting plates 21 connected by the hinges or creases can be folded when the air bag group 10 is inflated or deflated.

[0046] In an embodiment, the number of the adjusting plates 21 is greater than or equal to 4. For example, the number of the adjusting plates 21 is 5, 6, 8, 10, etc. The plurality of adjusting plates 21 completely covers the upper surface of the air bag group 10. The more the number of the adjusting plates 21, the more smooth the slope can be formed. The specific number of the adjusting plates 21 can be set according to actual needs, and the present disclosure does not make specific limitations.

[0047] In an embodiment, the adjusting plate 21 is a flat plate structure, which can be a plastic plate, a metal plate, or a fiber plate, etc. Further, the adjusting plate 21 is a PVC plate, which has high hardness, excellent aging resistance and flame retardant performance. By laying the PVC plate on the air bag group 10, the strength is more excellent.

[0048] It can be understood that, in an embodiment, the adjusting plate 21 can be simply laid on the air bag group 10 without being fixed with the air bag group 10. In other embodiments, the adjusting plate 21 can also be fixed with the upper surface of the air bag group 10 by adhesives or the like, which realizes the relative fixation of the adjusting plate 21 and the air bag group 10, and ensures that the adjusting plate 21 can tilt with the inflation and deflation of the air bag group 10.

[0049] In an embodiment, the artificial terrain layer 100 further includes a buffer layer 30, which is arranged on the bottom surface of the air bag group 10. By arranging the buffer layer 30 on the bottom surface of the air bag group 10, the buffer layer 30 can provide buffering and strength support for the air bag group 10, so as to prolong the service life of the product.

[0050] Further, the material of the buffer layer 30 can be rubber material, silicone material, foamed plastic, fiber material, or sponge material, etc. For example, in an embodiment, the buffer layer 30 selects a foamed EVA plate, which has excellent buffering, softness, heat insulation, and water resistance, etc., and can provide good support and elastic buffering for the air bag group 10.

[0051] In an embodiment, the artificial terrain layer 100 further includes a covering layer 40. The air bag group 10, the adjusting layer 20, and the buffer layer 30 are covered in the covering layer 40, and the covering layer 40 is provided with one or more openings 41 for the air guide pipe 360 of the inflation device 300 to enter and exit. The covering layer 40 has a certain accommodating space, which can be a cloth bag, etc. By packaging the air bag group 10, the adjusting layer 20, and the buffer layer 30 by the covering layer 40, the displacement or damage of the air bag group 10 can be avoided.

[0052] Referring to FIG. 4 and FIG. 5, in the embodiment, the air bag group 10 includes at least two air bags 11 independent from each other, and the air bags have a substantially blade-shaped cross section. Specifically, the air bags 11 have a straight edge 101 and an arc-shaped edge 102 on opposite sides, respectively, and the straight edge 101 and the arc-shaped edge 102 are connected at one end of the air bag 11 to form a pointed end structure, and the straight edge 101 and the arc-shaped edge 102 are connected at the other end of the air bag 11 by a connecting edge 103. The straight edge 101 and the connecting edge 103 are substantially perpendicular, so that the air bag 11 has a blade-shaped structure. The air bag 11 is arranged in a specific blade shape, so that when the air bag is inflated, a more realistic court terrain can be simulated.

[0053] In the embodiment, the projections of the two air bags 11 on the horizontal plane have overlapping regions. Specifically, the two air bags 11 can have overlapping regions in the x-axis direction, or the two air bags 11 can have overlapping regions in the y-axis direction. The x-axis direction is the width direction of the air bag 11, and the y-axis direction is the length direction of the air bag 11, and the x-axis direction and the y-axis direction are perpendicular to each other.

[0054] It should be noted that in other embodiments, the two air bags 11 can have overlapping regions in the x-axis direction and overlapping regions in the y-axis direction.

[0055] By arranging the two air bags 11 to have partially overlapping regions, after inflation, the overlapping regions have a higher height, and the non-overlapping regions have a lower height, thereby forming a high-low undulating slope.

[0056] Further, in one of the embodiments, the two air bags 11 independent from each other are defined as an air bag pair, and the air bag group 10 includes a first air bag pair 110 and a second air bag pair 120.

[0057] Further, in one of the embodiments, the air bags of the first air bag pair 110 have a length greater than the air bags of the second air bag pair 120, and the air bags of the first air bag pair 110 have a width smaller than the air bags of the second air bag pair 120. By this arrangement, the air bags of the first air bag pair 110 are relatively narrow and long, and the air bags of the second air bag pair 120 are relatively wide and short, which can better simulate different terrains.

[0058] It should be noted that in other embodiments, the first air bag pair 110 and the second air bag pair 120 can be arranged as multiple groups, and the specifications of the different air bag pairs can be the same or different.

[0059] Further, in one embodiment, the first air bag pair 110 and the second air bag pair 120 have the same overlapping manner in the x-axis direction, and the first air bag pair 110 is taken as an example for description. The first air bag pair 110 has an air bag 111 and an air bag 112, and the air bag 111 and the air bag 112 are substantially mirror-symmetrically arranged. The two air bags 111 and 112 are away from each other near one side of the straight edge 101 and close to each other near one side of the arc-shaped edge 102. The air bag 111 and the air bag 112 form an overlapping area A1 in the x-axis direction near one side of the arc-shaped edge 102.

[0060] Similarly, the second air bag pair 120 has an air bag 121 and an air bag 122, and the air bag 121 and the air bag 122 form an overlapping area A2 in the x-axis direction. By mirror-symmetrically arranging the two air bags and forming an overlap on one side of the arc-shaped edge, a more variable slope is formed after inflation, which is closer to the structure of a real natural putting green.

[0061] Please refer to FIG. 6, further, in the first air bag pair 110 / second air bag pair 120, the connecting edges 103 of the two air bags are arranged in parallel. The overlapping width of the two air bags in the x-axis direction is 1 / 10-1 / 3 of the maximum width of the air bags. Taking the first air bag pair 110 as an example, the overlapping width of the air bag 111 and the air bag 112 in the x-axis direction is D0, the maximum width of the air bag 111 and the air bag 112 is D1, and D0 is 1 / 10-1 / 3 of D1. For example, D0 can be 1 / 10, 1 / 5, 1 / 3, etc. of D1. By adjusting the size of the overlapping area, the simulated terrain can be better controlled to meet different practice needs.

[0062] It should be noted that the overlapping width of the first air bag pair 110 and the second air bag pair 120 in the x-axis direction can be the same or different, and the present disclosure does not make specific limitations.

[0063] Further, in the y-axis direction, the first air bag pair 110 and the second air bag pair 120 have overlapping areas. Specifically, the air bag 111 and the air bag 121 form an overlapping area B1 in the y-axis direction, and the air bag 121 and the air bag 122 form an overlapping area B2 in the y-axis direction. Further, the first air bag pair 110 and the second air bag pair 120 have the same orientation in the y-axis direction, that is, the tip structures of the first air bag pair 110 and the second air bag pair 120 are oriented to the same side. The side near the tip structure of the first air bag pair 110 forms an overlapping area with the side near the connecting edge of the second air bag pair 120.

[0064] By making the two air bag pairs 110 and 120 overlap in the y-axis direction, the variability of the slope structure is further improved, various slope states are formed, and different course terrains are constructed, which is more conducive to golf practice and improves the interest of users.

[0065] Further, in one of the embodiments, the straight edges of the first air bag pair 110 and the second air bag pair 120 are substantially flush, the overlapping length of the first air bag pair 110 and the second air bag pair 120 is L0, the length of the second air bag pair 120 is L1, and L0 is 1 / 3-2 / 3 of L1. For example, L0 is 1 / 3, 1 / 2, 2 / 3, etc. of L1. By adjusting the size of the overlapping area, the simulated terrain can be better controlled to meet different training needs.

[0066] Further, in one of the embodiments, the air bags 11 in the air bag group 10 are arranged in pairs. For example, the air bag 111 is arranged in overlapping relationship with the air bag 121 and the air bag 112, and the air bag 112 is arranged in overlapping relationship with the air bag 111 and the air bag 122. By arranging in pairs, a complex and variable slope structure is created.

[0067] Inflating device 300

[0068] Referring to FIGS. 7-9, the inflating device 300 includes a gas pump 330 and a plurality of independent air guide tubes 360. Each air bag 11 is in communication with the gas pump 330 via the air guide tube 360. The gas pump 330 is externally arranged outside the artificial terrain layer 100. Specifically, the gas pump 330 is externally arranged by connecting the gas pump 330 and the air bags 11 of the artificial terrain layer 100 via the air guide tube 360. The external arrangement of the gas pump 330 can reduce the volume of the entire artificial terrain layer 100 and facilitate the inflation and deflation control and maintenance of the equipment.

[0069] In one of the embodiments, the air guide tube 360 is in communication with the gas pump 330 via a pluggable male connector 310 and a female connector 320. Specifically, the gas pump 330 and the female connector 320 are installed in a housing 301. One end of the male connector 310 is in communication with the air guide tube 360, and the other end is inserted into the female connector 320 to connect the air bag 11 and the gas pump 330.

[0070] In one of the embodiments, the female connector 320 is provided with one or more front-to-back through flow channels 321, and the flow channels 321 are in communication with the gas pump 330 via an inner guide tube (not shown). Specifically, the flow channels 321 are outwardly protruded on the side away from the male connector 310 to form a first connection end 322, and the first connection end 322 is used to connect with the inner guide tube. Further, the end of the first connection end 322 is provided with a tapered flange 323. The bottom surface of the tapered flange 323 and the side wall of the first connection end 322 form a stepped shape, which can make the first connection end 322 more stably clamped in the inner guide tube and avoid falling off during air flow delivery. The number of flow channels 321 can be determined according to the number of air bags, for example, 1, 3, 4, etc., which is not specifically limited in the present disclosure.

[0071] Further, the female joint 320 is provided with one or more connecting holes 324, and the female joint 320 is locked and fixed in the shell 301 by cooperating with the connecting holes 324 through fasteners such as screws.

[0072] In an embodiment, the shell 301 is provided with a first opening hole 302 matched with the flow guide channel 321. The male joint 310 is provided with one or more tracheal joints 311, one end of the tracheal joint 311 penetrates through the first opening hole 302 and is inserted into the flow guide channel 321 one by one. The other end of the tracheal joint 311 is used to be connected to the air bag through the air duct 360, so that the air duct 360 and the inner catheter are communicated, thereby realizing the conduction between the air bag and the air pump 330.

[0073] In order to ensure the sealing of gas transmission, the tracheal joint 311 of the male joint 310 and the flow guide channel 321 are sealingly inserted and matched through the sealing element 350. Specifically, the sealing element 350 includes a sealing plate 351 and a plug 352 protruding on the sealing plate 351, the plug 352 protrudes towards the female joint 320, and the front and rear ends are throughly arranged. The plug 352 is provided with one or more and is inserted into the flow guide channel 321 one by one, and the end of the tracheal joint 311 is inserted into the plug 352, so that the gap between the tracheal joint 311 and the flow guide channel 321 is closed by the sealing element 350. The sealing element 350 is an integral structure, and the material of the sealing element 350 can be, for example, silica gel or rubber, etc., to ensure good sealing effect.

[0074] Further, the side of the shell 301 towards the male joint 310 is recessed to form a socket 340, and the first opening hole 302 is arranged in the socket 340, and the end of the male joint 310 is inserted into the socket 340. Specifically, the profile of the socket 340 is substantially consistent with the profile of the end of the male joint 310. By inserting the male joint 310 into the socket 340, the inner wall of the socket 340 limits and blocks the circumferential side of the male joint 310, so as to effectively improve the connection stability of the insertion structure.

[0075] Further, in an embodiment, the male joint 310 is provided with an elastic clamping element 314, and the socket 340 is provided with a clamping groove 341 matched with the elastic clamping element 314, so as to clamp and fix the male joint 310 with the shell 301. Specifically, the elastic clamping element 314 includes clamping hooks arranged on both sides of the male joint 310 respectively. The clamping hooks are clamped with the clamping groove 341, and the side of the clamping hooks away from the clamping groove 341 forms a avoiding space, and the clamping hooks can be deformed when subjected to pressure, thereby separating from the clamping groove 341 and releasing the locking state with the shell 301.

[0076] Further, in one embodiment, the tracheal connector 311 has a second connecting end 312 protruding towards the female connector 320 and a third connecting end 313 protruding towards the air guide tube 360. The second connecting end 312 is used to be inserted into the flow guide channel 321 of the female connector 320, and the third connecting end 313 is used to be connected with the air guide tube 360.

[0077] Further, in this embodiment, the end of the second connecting end 312 is provided with a guide slope 315, which is generally a conical surface. By providing the conical guide slope, the second connecting end 312 can be more smoothly inserted into the flow guide channel 321.

[0093] Through the setting of the first valve group 410 and the second valve group 420, the inflation control and the deflation control of each air bag 11 can be realized through the same air pump 330. During the deflation process, the deflation speed is fast and the efficiency is high due to the participation of the air pump 330. In addition, the inflation process and the deflation process of each air bag 11 can be controlled individually, which greatly facilitates the slope adjustment of the artificial terrain layer 100.
