Description

Technical Field

[0001] This application relates to the field of automatic control technology for sports fields, and in particular to field switching devices and stadium fields. Background Technology

[0002] Currently, in some regions, the popularity of tennis and badminton differs, which may lead to certain types of courts being underutilized. For example, tennis courts may experience lower foot traffic in certain seasons, while badminton courts are more commonly used for indoor activities. Additionally, the training and competition schedules for different sports may not align, resulting in underutilization of facilities.

[0003] The design and usage characteristics of tennis and badminton courts make these two types of venues generally unsuitable for sharing, leading to a waste of resources and space. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this application provides a field switching device and a stadium field.

[0005] According to a first aspect of the embodiments of this application, a court switching device is provided. The court switching device includes: a sideline assembly, including tennis line units and badminton line units; the badminton line units are located within the space enclosed by the tennis line units, and the center lines of the two units coincide; a net assembly, including a net and a club, the net being fixed to the club and moving up and down with the club; the net assembly is arranged along the center line of the tennis line units and the badminton line units, and both ends of the club are fixed outside the space enclosed by the tennis line units; the court switching device is used to switch between a first state and a second state. When the court switching device is in the first state, the net is located at a first height; when the court switching device is in the second state, the net is located at a second height, the first height being greater than the second height. The sideline assembly is used to mark the area and sidelines when the court is used as a tennis court and to mark the area and sidelines when the court is used as a badminton court. The coincidence of the center lines of the tennis line units and the badminton line units avoids the need to modify the net position when changing the usage state, simplifying the difficulty of use. The net is set on the center line of the court, with the ends of the net-fixing sticks positioned outside the tennis court's string units to avoid interfering with normal operation within the court area. The court switching device can switch between a first state and a second state. In the first state, it is used as a badminton court; in the second state, it is used as a tennis court. Since the area of ​​a badminton court is smaller than that of a tennis court, only the area originally used for a tennis court is required, reducing the footprint and saving space.

[0006] Furthermore, the badminton string unit is used for illumination; when the court switching device is in the second state, the badminton string unit is turned off. When the court switching device is in the second state, the court is used as a tennis court, and the badminton string unit is turned off to avoid affecting the user's judgment due to some badminton string units being too close to some tennis string units.

[0007] Furthermore, during the switching process between the first and second states of the court switching device, the badminton shuttlecock unit is exposed to the outside environment. The badminton shuttlecock unit can be directly installed on the ground and connected to the atmosphere, which offers the advantages of simple installation and ease of construction.

[0008] Furthermore, the badminton string unit includes a light source and a downwardly recessed groove. The light source is disposed within the groove, and its illumination differs when the court switching device switches between the first and second states. The badminton string unit also includes a shielding member, at least a portion of which is located at the opening of the groove. The upper surface of the shielding member is not higher than the upper surface of the tennis string unit. The light source of the badminton string unit is disposed within the groove to prevent it from protruding above the ground and affecting the actual use of the court. Simultaneously, a shielding member is positioned above the light source within the groove to cover the opening of the groove. The upper surface of the shielding member is not higher than the upper surface of the tennis string unit to keep the ground flat and prevent personal safety accidents during user operation.

[0009] Further, the shielding component includes a first baffle made of opaque material; when the court switching device is in the second state, the first baffle is positioned above the light source in the vertical direction; and / or, the shielding component includes a second baffle made of transparent material; when the court switching device is in the first state, the second baffle is positioned above the light source in the vertical direction. When the court switching device is in the second state, the court is used as a tennis court. At this time, the opaque first baffle is positioned above the light source, blocking the light emitted by the badminton string unit's light source from entering the human eye, and only the tennis string unit is visible. When the court switching device is in the first state, the court is used as a badminton court. At this time, the transparent second baffle is positioned above the light source, allowing the light emitted by the badminton string unit's light source to enter the human eye, and only the badminton string unit is visible.

[0010] Furthermore, the second baffle is red; and / or, the light emitted by the light source is red. The second baffle being red, or the light emitted by the badminton shuttlecock unit being set to red, improves the visibility of the badminton shuttlecock unit when the court switching device is in the first state, making it easier to spot and identify.

[0011] Further, when the shielding member includes the first baffle and the second baffle, one end of the first baffle and the second baffle are fixedly connected; the groove includes a first space and a second space; the second space includes a first part and a second part, the first part is located above the first space, and at least a portion of the structure in the second part is located on the side of the first space; the light source is disposed in the first space, and the shielding member is disposed in the second space; when the site switching device is in the first state, the second baffle is located in the first part of the second space, and the first baffle is located in the second part of the second space; when the site switching device is in the second state, the first baffle is located in the first part of the second space, and the second baffle is located in the second part of the second space. The groove includes a first space and a second space, the first space is used to accommodate the light source, the second space is used to accommodate the shielding member, and at least a portion of the structure in the second space is located above the first space, wherein the portion of the second space located above the first space is called the first part, and the portion of the second space located on the side of the first space is called the second part. When the court switching device is in its first state, the court is used as a badminton court. In this state, the transparent second barrier needs to be positioned above the light source, so the second barrier is adjusted to the first part, and the first barrier is adjusted to the second part. When the court switching device is in its second state, the court is used as a tennis court. In this state, the opaque first barrier needs to be positioned above the light source, so the first barrier is adjusted to the first part, and the second barrier is adjusted to the second part. Through the above settings, the different requirements of the court switching device state can be met by adjusting the positions of the first and second barriers.

[0012] Furthermore, the second space encompasses the first space; the badminton shuttlecock-shaped unit includes a driving device, which drives the second space, and the shielding member is made of a flexible material. The driving device is used to drive the shielding member to move within the second space. The second space encompasses the first space, meaning the second space surrounds the outside of the first space. The shielding member moves within the second space. Since movement within the second space involves shape changes, the shielding member needs to be made of a flexible material to allow for free deformation and movement. The driving device is used to drive the shielding member.

[0013] Furthermore, the badminton shuttlecock-shaped unit includes a support member disposed within the groove. The strength of the support member is greater than the strength of the shielding member. The support member is located on the side of the shielding member away from the light source; or, the support member is located on the side of the shielding member closer to the light source. The support member's strength is greater than the shielding member's strength, preventing deformation due to excessive flexibility and ensuring structural stability. When the support member is located on the side of the shielding member away from the light source, it prevents the shielding member from being too flexible to support high-intensity movements by the user. When the support member is located on the side of the shielding member closer to the light source, it prevents the shielding member above the light source from being too flexible and lacking sufficient strength, thus avoiding downward sagging and affecting structural stability.

[0014] Furthermore, the net assembly also includes a post with at least two insertion holes. The shuttlecock can be inserted into these holes, which include at least a first insertion hole and a second insertion hole, with the height of the first insertion hole being greater than the height of the second insertion hole. The at least two insertion holes on the post, with the first insertion hole higher than the second insertion hole, allow the user to freely adjust the height of the shuttlecock and the net, increasing its applicability, expanding usage scenarios, and facilitating adjustment. The first insertion hole corresponds to the badminton application scenario when the court switching device is in its first state, and the second insertion hole corresponds to the tennis application scenario when the court switching device is in its second state.

[0015] Furthermore, the net assembly also includes two posts and a power source. The posts are fixed outside the space enclosed by the tennis string units, and both ends of the club are fixed to the two posts respectively. The power source drives the posts to move and moves the club up and down. The posts are positioned outside the space enclosed by the tennis string units to avoid obstructing the tennis court space and reduce potential user experience issues. The power source drives the posts according to the state of the court switching device, adjusting the post height, and thus adjusting the height of the club and net, achieving automatic adjustment of the net height under different conditions.

[0016] Furthermore, each of the aforementioned posts includes a first post and a second post. The first post is sleeved on the outside of the second post. The second post is connected to the power source and can move vertically within the first post. The power source is used to drive the movement of the second post within the first post. The first post and the second post are sleeved together, and the power source drives the second post to move up and down to change the height of the cue stick.

[0017] Furthermore, the net assembly also includes a transmission mechanism. The power source is connected to the transmission mechanism to drive its movement, and the transmission mechanism is fixedly connected to the upright. The power source drives the upright through the transmission mechanism to raise and lower the club and the net. Simultaneously, the transmission mechanism is fixedly connected to the upright to enable the power source to drive the upright.

[0018] Furthermore, one of the columns is fixedly connected to the cue stick and has a fixed transmission mechanism. The transmission mechanism directly drives the column to move, thereby causing the cue stick fixed to the column to move up and down. The other column is slidably connected to the cue stick. Alternatively, both columns are fixedly connected to the cue stick, and both columns have the transmission mechanism fixed to them. The power source is used to drive the two columns to move synchronously. When one column is fixedly connected to the cue stick, the power source drives one column to move, thereby causing the cue stick to move up and down, and the other end of the cue stick slides in the other column. This configuration reduces the power required by the power source and requires less space and fewer components, thus reducing production costs. When both columns are fixedly connected to the cue stick, the power source simultaneously drives both columns to move synchronously, thereby causing the cue stick to move up and down. This configuration has the advantages of high column movement synchronization and good stability.

[0019] Furthermore, the net assembly includes a downwardly recessed receiving groove, which is at least used to accommodate the power source; the net assembly also includes a shielding member that covers the opening of the receiving groove and has a gap for the post to extend out. The receiving groove accommodates the power source, thereby reducing the ground space occupied by the net assembly and saving space. The shielding member reduces the opening gap of the receiving groove, reducing or preventing balls or debris from falling into the receiving groove, extending its service life, and reducing maintenance difficulty.

[0020] Furthermore, the net assembly also includes a shielding cover, which is mounted on the upright. The shielding cover has a net outlet on its side, allowing the net to move along the outlet. The shielding cover, mounted on the upright, has an opening on its side for the vertical movement of the club. The shielding cover reduces the number of balls or debris entering the receiving slot, extending its service life and reducing maintenance difficulty.

[0021] According to a second aspect of the embodiments of this application, a sports field is provided, comprising: a lighting mechanism and a field switching device as described above; the lighting mechanism is disposed outside the area enclosed by the tennis string units. Distributing the lighting mechanism outside the area enclosed by the tennis string units avoids the problem of the lighting mechanism occupying tennis court space and thus affecting user experience when the field is used as a tennis court.

[0022] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0023] Multi-functional venues can accommodate different sports within the same area, reducing the demand for venue resources. The venue design allows for adjustments based on time or event needs, making venue use more flexible. Building one venue instead of two separate venues can significantly reduce construction and maintenance costs, including venue materials, facilities, and management fees. Multi-functional venues reduce maintenance frequency and costs, allowing managers to concentrate resources on maintenance and facility upgrades. Furthermore, venues combining two sports can attract more participants, meaning more events and competitions, thereby increasing the venue's activity level.

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] Nowadays, the design and usage characteristics of tennis and badminton courts make it generally unsuitable for sharing these two types of venues. Therefore, when setting up these two types of venues, two separate courts are often built. However, due to differences in usage volume and time, the two different venues are often not fully utilized, which leads to a waste of resources and venues.

[0040] The inventors noticed this problem and, in order to overcome the existing problems, provided a field switching device and a stadium field that uses the field switching device.

[0041] Combination Figure 1 and Figure 2As shown, the sports field includes a court switching device, which comprises a sideline assembly 10 and a net assembly 20. The sideline assembly 10 includes a badminton string unit 200 and a tennis string unit 100. When the sports field needs to be used as a tennis court, the user can use the tennis string unit 100; when the sports field needs to be used as a badminton court, the user can use the badminton string unit 200. Since the area of ​​a badminton court is smaller than that of a tennis court, only the badminton string unit 200 and the tennis string unit 100 need to be placed inside each other, allowing the same area to be used as both a tennis court and a badminton court, reducing the overall footprint and saving space.

[0042] like Figure 2 As shown, the sideline component 10 is used to mark the area and sidelines when the court is used as a tennis court and when it is used as a badminton court. To better utilize the court, the badminton string unit 200 is placed within the space enclosed by the tennis string unit 100, and their center lines coincide. The coincidence of the center lines of the tennis string unit 100 and the badminton string unit 200 eliminates the need to adjust the position of the net component 20 when changing the usage mode, simplifying the use.

[0043] like Figure 3 As shown, the net assembly 20 includes a net 300 and a shuttlecock 400. The net 300 is fixed to the shuttlecock 400 and moves up and down with the shuttlecock 400. The net assembly 20 is arranged along the center line of the tennis ball line unit 100 and the badminton shuttlecock line unit 200, and both ends of the shuttlecock 400 are fixed outside the space enclosed by the tennis ball line unit 100.

[0044] In the above setup, the net 300 is positioned on the center line of the court, and the ends of the shuttlecock 400 that fixes the net 300 are positioned outside the tennis ball line unit 100 to prevent the shuttlecock 400 from interfering with the normal movement of users within the court area. In other words, when the stadium is used as a tennis court and when it is used as a badminton court, the same net is used in the same location; the only difference is the height of the net 300 from the ground. As described above, by changing the height of the net 300, the court can be adapted to different usage scenarios, reducing the maintenance cost of the net 300. At the same time, when users have different heights, the height of the shuttlecock 400 can also be adjusted according to actual needs, thereby adjusting the height of the net 300, improving the adaptability of the court to different users, and thus enhancing the user experience.

[0045] In this embodiment, the court switching device can switch between a first state S1 and a second state S2. When the court switching device is in the first state S1, the net 300 is at a first height. When the court switching device is in the second state S2, the net 300 is at a second height, and the first height is greater than the second height. In other words, when the court switching device is in the first state S1, the court can be used as a badminton court, and the user can use the badminton string unit 200 for training and matches; when the court switching device is in the second state S2, the court can be used as a tennis court, and the user can use the tennis string unit 100 for training and matches.

[0046] Because the usable area of ​​the court when used as a badminton court is smaller than that when used as a tennis court, the badminton line unit 200 is located within the sports field when the court is used as a tennis court, which may affect the user's judgment. Specifically, the distance from the tennis service line 110 to the net 300 is 6.4m, and the distance from the badminton court boundary line 201 to the net 300 is 6.7m, which can easily lead to misjudgment. To avoid this problem as much as possible, the inventors made further improvements:

[0047] The badminton shuttlecock linear unit 200 can be illuminated.

[0048] When the court switching device is in the second state S2 (i.e., when used as a tennis court), the badminton stringing unit 200 is turned off to minimize or avoid the badminton stringing unit 200 affecting the tennis player's judgment. The badminton stringing unit 200 can be illuminated. When the court switching device is in the first state S1 (i.e., when used as a badminton court), the badminton stringing unit 200 is illuminated, allowing the user to more clearly detect the badminton stringing unit 200, minimizing or avoiding the tennis stringing unit 100 affecting the tennis player's judgment.

[0049] Furthermore, the court switching device includes a control unit, and the badminton string unit 200 includes a light source 210 for emitting light. The control unit and the light source 210 of the badminton string unit 200 are electrically connected to control the lighting or extinguishing of the light source 210 in the badminton string unit 200. When the control unit receives a signal that the court needs to be switched to a badminton court, the control unit sends a lighting signal, and the light source 210 receives the lighting signal and emits light. At this time, the court switching device switches to the first state S1. When the control unit receives a signal that the court needs to be switched to a tennis court, the control unit sends an extinguishing signal, and the light source 210 receives the extinguishing signal and stops emitting light. At this time, the court switching device switches to the second state S2.

[0050] It should be noted that the "signal to switch the court to badminton court" and the "signal to switch the court to tennis court" received by the control unit mentioned above can be a voice signal issued by the user or other control signals.

[0051] Combination Figure 3 and Figure 4 As shown, in this embodiment, the badminton shuttlecock-shaped unit 200 includes a downwardly recessed groove 220, and the light source 210 is disposed in the groove 220. When the court switching device switches between the first state S1 and the second state S2, the light emission of the light source 210 is different.

[0052] In the above configuration, the light source 210 of the badminton shuttlecock linear unit 200 is disposed within the groove 220 to avoid affecting the actual use of the court due to the light source 210 protruding from the ground. In this embodiment, the badminton shuttlecock linear unit 200 includes a portion disposed below the ground. In other embodiments, the badminton shuttlecock linear unit 200 may be completely disposed above the ground (similar to an attached light strip). During the switching process between the first state S1 and the second state S2, the badminton shuttlecock linear unit 200 is exposed to the outside environment.

[0053] The badminton shuttlecock line unit 200 also includes a shielding member 230, at least a portion of the structure of which is located in the opening 225 of the groove 220, and the upper surface of the shielding member 230 is not higher than the upper surface of the tennis ball line unit 100.

[0054] In the above configuration, a shielding member 230 is provided above the light source 210 within the groove 220 to cover the opening 225 of the groove 220, and the height of the upper surface of the shielding member 230 is limited, which can prevent the risk of the user tripping over the protruding structure during use. In other embodiments, the light source 210 of the badminton stringing unit 200 can also be set to be continuously lit, and the relative positional relationship between the shielding member 230 and the opening 225 can be used to control whether the light emitted by the light source 210 of the badminton stringing unit 200 can enter the human eye. For example, when the court switching device is in the second state S2, the shielding member 230 blocks the light source 210 from shining outward through the opening 225 to prevent the light from entering the human eye. At this time, the human eye cannot see the badminton stringing unit 200, and the tennis stringing unit 100 can be used normally. When the court switching device is in the first state S1, the shielding member 230 allows the light source 210 to be emitted outward through the opening 225 and enter the human eye. At this time, the human eye can see the glowing badminton shuttlecock linear unit 200 more clearly.

[0055] Furthermore, such as Figure 3As shown, in this embodiment, the shielding member 230 includes a first baffle 231, which is made of an opaque material. When the court switching device is in the second state S2, that is, when the court is used as a tennis court, the first baffle 231 is positioned vertically above the light source 210. At this time, the opaque first baffle 231 can block the light source 210 of the badminton string unit 200 from being emitted outward through the opening 225, thereby preventing light from entering the human eye. In this case, only the tennis string unit 100 is visible, allowing the user to engage in tennis activities.

[0056] like Figure 4 As shown, the shielding member 230 also includes a second baffle 232, which is made of transparent material. When the court switching device is in the first state S1, that is, when the court is used as a badminton court, the transparent second baffle 232 allows the light source 210 of the badminton chord unit 200 to be emitted outward through the opening 225 so that light can enter the human eye. In this case, the badminton chord unit 200 is visible for the user to use for badminton activities.

[0057] Specifically, in this embodiment, the second baffle 232 is red to filter light. The red color of the second baffle 232 increases the visibility of the badminton stringing unit 200 when the court switching device is in the first state S1, making it easier to spot and identify. At this time, the light source 210 can emit white light, which, under the filtering effect of the second baffle 232, emits red light downwards. In other embodiments, the color of the second baffle 232 can be other colors, or the light emitted by the light source 210 of the badminton stringing unit 200 can be red. Changing the color of the second baffle 232 or the color of the light emitted by the light source 210 of the badminton stringing unit 200 is intended to affect the visibility of the badminton stringing unit 200 in the human eye, creating a sharp contrast with the tennis stringing unit 100, and preventing users from being affected by the tennis stringing unit while using a sports field as a badminton court.

[0058] Combination Figure 3 and Figure 4 As shown, one end of the first baffle 231 and the second baffle 232 are fixedly connected. By moving one end of the blocking member 230, the positions of the first baffle 231 and the second baffle 232 can be changed synchronously.

[0059] Furthermore, in combination Figure 5As shown, the groove 220 includes a first space 221 and a second space 222. The second space 222 includes a first portion 223 and a second portion 224. The first portion 223 is located above the first space 221 and in the region of the opening 225. At least a portion of the structure in the second portion 224 is located on the side of the first space 221. The light source 210 is disposed in the first space 221. Figures 3-5 As shown, the blocking member 230 is disposed in the second space 222. The blocking member 230 needs to be able to block the light source 210, so it is provided with a first portion 223 located on the upper part of the first space 221. The blocking member 230 also needs to have a receiving space when it does not block the light source 210, so it is provided with a second portion 224 located on the side of the first space 221.

[0060] It should be noted that, in Figure 5 In this design, different spatial regions are represented by cross-sectional lines with varying inclination directions. Furthermore, to better observe these spatial regions, [further details are needed]. Figure 5 The middle part shows the shading component.

[0061] Combination Figures 3-5 As shown, when the court switching device is in the first state S1, the second baffle 232 is located in the first part 223 of the second space 222, and the first baffle 231 is located in the second part 224 of the second space 222. When the court switching device is in the second state S2, the first baffle 231 is located in the first part 223 of the second space 222, and the second baffle 232 is located in the second part 224 of the second space 222. When the court switching device is in the first state S1, the court is used as a badminton court. At this time, the transparent second baffle 232 needs to be located above the light source 210, so the second baffle 232 is adjusted to the first part 223, and the first baffle 231 is adjusted to the second part 224. When the court switching device is in the second state S2, the court is used as a tennis court. At this time, the opaque first baffle 231 needs to be located above the light source 210, so the first baffle 231 is adjusted to the first part 223, and the second baffle 232 is adjusted to the second part 224. With the above settings, the different requirements of the site switching device state can be met by adjusting the positions of the first baffle 231 and the second baffle 232.

[0062] In this embodiment, the second space 222 is disposed at the top and side of the first space 221. Of course, in other embodiments, such as... Figure 6 As shown, the second space 222 can also enclose the periphery of the first space 221. In this case, combined with... Figure 6 and Figure 7As shown, the shielding member 230 is located in the second space 222 and surrounds the first space. The badminton shuttlecock linear unit 200 includes a driving device 240, which drives the shielding member 230 to move within the second space 222. The second space 222 encloses the first space 221, i.e., the second space 222 surrounds the outside of the first space 221. When the shielding member 230 moves within the second space 222, the driving device 240 drives the remaining portion of the shielding member 230 to move by driving the portion of the shielding member 230 that contacts the driving device 240. The shielding member 230 is made of a flexible material. Because the second space 222 encloses the first space 221, the movement path of the shielding member 230 is not straight. Therefore, movement within the second space 222 involves shape changes, so the shielding member 230 needs to be made of a flexible material to allow for free deformation and movement. At this time, the shielding member 230 also includes a flexible portion 233, the two ends of which are respectively connected to the first baffle 231 and the second baffle 232. In other words, the flexible portion 233, the first baffle 231, and the second baffle 232 are connected to form a ring structure and wrap around the periphery of the first space 221. The flexible portion 233 is used to cooperate with the driving device 240, that is, the driving device 240 can drive the flexible portion 233 to move, thereby driving the first baffle 231 and the second baffle 232 to move. Of course, in other embodiments, the flexible portion 233 can be a partial structure of the first baffle 231 and / or the second baffle 232.

[0063] It should be noted that, in Figure 6 In this design, different spatial regions are represented by cross-sectional lines with varying inclination directions. Furthermore, to better observe these spatial regions, [further details are needed]. Figure 6 The middle part shows the shading component.

[0064] In addition, such as Figure 8 As shown, the badminton shuttlecock linear unit 200 includes a support member 250, which is disposed in the groove 220. The strength of the support member 250 is greater than the strength of the blocking member 230. The strength of the support member 250 is used to maintain the structural stability within the groove 220 and prevent collapse or other phenomena.

[0065] In this embodiment, the support member 250 is located on the side of the shielding member 230 away from the light source 210 and on the side of the shielding member 230 closer to the light source 210. The support member 250 located on the side of the shielding member 230 away from the light source 210 prevents the shielding member 230 from being too flexible to support high-intensity movements by the user. The support member 250 located on the side of the shielding member 230 closer to the light source 210 prevents the shielding member 230 above the light source 210 from being too flexible and therefore lacking strength, which could cause it to sag and affect structural stability. Of course, in other embodiments, using only one type of support member 250 can also achieve improved stability.

[0066] Furthermore, such as Figure 9 As shown, the net assembly also includes a post 500, which has at least two insertion holes 510. The ball stick 400 can be inserted into the insertion hole 510, and the insertion hole 510 includes at least a first insertion hole 511 and a second insertion hole 512, wherein the height of the first insertion hole 511 is greater than the height of the second insertion hole 512.

[0067] In the above configuration, the post 500 has at least two sockets 510, with the first socket 511 higher than the second socket 512. The user can freely adjust the fixed position of the cue stick 400, thereby adjusting the height of the net 300. In other words, the user can fix the cue stick 400 in the first socket 511, at which point the net 300 is at a first height, and the court switching device is in the first state S1. The user can also fix the cue stick 400 in the second socket 512, at which point the net 300 is at a second height, and the court switching device is in the second state S2. This operation is convenient. It should be noted that the method mentioned above uses only one cue stick 400 to fix the net 300, that is, the upper end of the net 300 is fixed to the cue stick 400. Of course, in other embodiments, two cue sticks 400 distributed vertically can be used to fix the upper and lower ends of the net 300 respectively. In this case, the number of sockets 510 needs to be increased accordingly. In addition, the number of sockets 510 can be greater than two, allowing users to flexibly adjust the fixed position of the cue stick 400 according to their actual height and other factors, thereby improving the user experience.

[0068] In another embodiment, such as Figure 10As shown, the net assembly 20 also includes two posts 500 and a power source 600. The posts 500 are fixed outside the space enclosed by the tennis ball string unit 100, and both ends of the club 400 are fixed to the two posts 500 respectively. The posts 500 are positioned outside the space enclosed by the tennis ball string unit 100 to avoid occupying the tennis court space and reduce potential issues that might negatively impact user experience.

[0069] The power source 600 is used to drive the column 500 to move and drive the cue stick 400 to move up and down. The power source 600 drives the column 500 according to the state of the court switching device, adjusts the height of the column 500, and then adjusts the height of the cue stick 400 and the net 300, so as to realize the automatic adjustment of the height of the net 300 under different states.

[0070] In the above configuration, the net assembly 20 further includes a transmission mechanism. The power source 600 is connected to the transmission mechanism to drive its movement. The transmission mechanism is fixedly connected to the column 500. The power source 600 drives the column 500 through the transmission mechanism to raise and lower the cue stick 400 and the net 300. Simultaneously, the transmission mechanism is fixedly connected to the column 500 to enable the power source 600 to drive the column 500.

[0071] In this embodiment, both columns 500 are fixedly connected to the cue stick 400, and both columns 500 are fixedly equipped with the transmission mechanism. The power source 600 is used to drive the two columns 500 to move synchronously. Specifically, the transmission mechanism may include a fixedly connected shaft and a gear, and a rack that meshes with the gear is provided on the column 500. The output end of the power source 600 is fixedly connected to the shaft. In use, the power source 600 drives the shaft to rotate, which in turn drives the gear fixed on the shaft to rotate. The rotation of the gear drives the rack fixed to the column 500 to move, thereby moving the column 500 and realizing the up-and-down movement of the cue stick 400 and the net 300. With the above configuration, when both columns 500 are fixedly connected to the cue stick 400, the power source 600 simultaneously drives both columns 500 to move synchronously, thereby driving the cue stick 400 to move up and down. This configuration has the advantages of high synchronization of column movement and good stability.

[0072] Of course, in other embodiments, one of the columns 500 can be fixedly connected to the cue stick 400 and has a fixed transmission mechanism. The transmission mechanism directly drives the column 500 to move, thereby driving the cue stick 400 fixed on the column 500 to move up and down. The other column 500 and the cue stick 400 are slidably connected. When one column 500 is fixedly connected to the cue stick 400, the power source 600 drives one column 500 to move, thereby driving the cue stick 400 to move up and down, and the other end of the cue stick 400 slides in the other column 500. The above arrangement can reduce the power required by the power source 600, and requires less space and fewer components when setting the power source 600, thus reducing production costs.

[0073] Specifically, each of the uprights 500 includes a first column 520 and a second column 530. The first column 520 is sleeved on the outside of the second column 530. The second column 530 is connected to the power source 600 and can move vertically within the first column 520. The power source 600 is used to drive the movement of the second column 530 within the first column 520. The first column 520 and the second column 530 are sleeved together, and the power source 600 drives the second column 530 to move up and down to change the height of the cue stick 400.

[0074] It should be noted that the power source 600 is electrically or communicatively connected to the control unit, and the control unit can control the movement of the power source 600 according to the received instructions.

[0075] Continue as Figure 10 As shown, the net assembly 20 includes a downwardly recessed receiving groove 700, which is used to accommodate at least the power source 600, thereby reducing the ground space occupied by the net assembly 20 and saving space.

[0076] The ball net assembly 20 also includes a shielding member 800, which shields the opening of the receiving groove 700 and has a gap for the post 500 to extend out. The shielding member 800 is used to reduce the opening gap of the receiving groove 700, reduce or prevent balls or debris from falling into the receiving groove 700, extend service life, and reduce maintenance difficulty.

[0077] The net assembly 20 also includes a shielding cover 900, which is mounted on the upright 500. The shielding cover 900 has a net outlet 910 on its side, allowing the net to move along the outlet 910. The shielding cover 900, mounted on the upright 500, provides sufficient space for the vertical movement of the clubs and net. The shielding cover 900 reduces or prevents external impurities and balls from entering the receiving groove 700, extending its service life and reducing maintenance difficulty. Furthermore, a screen can be installed on the shielding cover 900 to display scores, advertisements, venue information, etc.

[0078] This application also discloses a sports field that includes a lighting mechanism and the aforementioned field switching device. The lighting mechanism is located outside the area enclosed by the tennis string units.

[0079] It should be noted that the lighting mechanism and the control unit are electrically or communicatively connected. The control unit can control the lighting mechanism in different states according to received instructions. Different lighting states include, but are not limited to: on, off, brightness, and beam angle.
