Description

Technical Field

[0001] This utility model relates to the field of stadium screen technology, and in particular to an electronic stadium screen. Background Technology

[0002] In sports event operations and stadium management, electronic stadium screens, as core information interaction devices, need to meet diverse needs such as displaying match scores, announcing match rules, placing advertisements, and facilitating audience interaction. Their performance directly impacts the presentation of the event and the user experience. However, existing electronic stadium screens still face many problems that urgently need to be addressed in practical applications.

[0003] The existing electronic stadium screens are mostly rigid fixed structures with no buffered movable connection design between the base and the ground, or between the screen and the supporting components. When subjected to external forces such as accidental collisions by players, the impact force is directly transmitted to the main body of the screen. Due to the lack of a buffer movement mechanism after impact, the existing equipment cannot mitigate the impact force in the direction of impact through small movements of its own structure. The rigidly transmitted impact force may cause the entire equipment to tip over, causing safety risks such as bumps and injuries to surrounding personnel (such as players, spectators, and staff). Therefore, this application proposes an electronic stadium screen. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electronic stadium screen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic stadium screen, comprising: The base plate is set in a "U" shape and is horizontal. A fixed shaft is installed at the front end of the top of the base plate, and sliding grooves extending to the rear end are opened on both sides of the bottom of the base plate. Wheel grooves are opened at the two corners of the bottom front end of the base plate, and rotatable rollers are installed in the two wheel grooves. The screen body has hinge blocks installed at the two corners at the bottom of the back, and both hinge blocks are sleeved on the fixed shaft. The support adjustment components are provided in two sets, with the two support adjustment components respectively located between the two corners at the top of the back of the screen and the two corners at the rear of the top of the base plate; The base has two sets of sliding grooves that are slidably installed on the bottom of the base plate, and the bottom of the base and the bottom of the roller are at the same level.

[0006] Optionally, the support adjustment assembly includes a fixed tube, a support rod, a telescopic rod, a connecting block, and a connecting rod. Two fixed tubes are provided and installed at the corner of the top rear end of the base plate. Two support rods are provided, with the bottom ends of the two support rods movably inserted into the two fixed tubes respectively. Two connecting blocks are provided, and the two connecting blocks are respectively installed at the top of the two support rods. The connecting rod is fixedly connected between the two connecting blocks. The top of each of the two support rods has a slot. Each of the two connecting blocks has an insertion hole aligned with the corresponding slot. Two telescopic rods are provided, with the bottom ends of the two telescopic rods passing through the two insertion holes and inserted into the corresponding slots. The top ends of the two telescopic rods are fixedly connected to the back of the screen. A second spring is fixedly connected between the bottom end of each of the two telescopic rods and the inner end of the slot.

[0007] Optionally, the support adjustment assembly also includes a fixing member and a hydraulic rod. The fixing member is fixedly installed on the top of the base plate and located between two fixing tubes. The bottom end of the hydraulic rod is hinged to the fixing member, and the telescopic end of the hydraulic rod is hinged to the connecting rod.

[0008] Optionally, the fixed tube, support rod, and telescopic rod are all designed in an arc shape, and the center of the fixed tube, support rod, and telescopic rod is on the same horizontal axis as the fixed axis.

[0009] Optionally, sliders are installed at the middle positions on both sides of the inner wall of the sliding groove, and positioning holes are opened on the sliders. The cross-section of the base is "convex" shaped, and positioning rods are installed at the top of the horizontal sections on both sides of the base. The positioning holes on the two sliders inside the sliding groove are respectively fitted onto the corresponding positioning rods on the base. Countersunk holes are opened at the four corners of the horizontal section of the base, and bolts are inserted into each countersunk hole.

[0010] Optionally, a fixing plate is installed at the bottom of each of the two sliding grooves near the roller, and a rod groove is opened at the end of each of the two bases near the fixing plate. A guide rod is installed at the fixing plate of each of the two sliding grooves, and the two guide rods are respectively inserted into the corresponding rod grooves. A first spring is sleeved on each of the two guide rods, and the two ends of the first spring are respectively connected to the fixing plate and the base.

[0011] The beneficial effects of this utility model are: The base and the base plate are connected by a guide rod and a first spring to form a buffer structure. When the equipment is impacted by an external force, the base can slide slightly along the sliding groove. The first spring can absorb and mitigate the impact force, avoid rigid transmission that could cause the equipment to tip over, and reduce the risk of collisions with surrounding players and spectators. The second spring in the support and adjustment assembly, in conjunction with the telescopic rod design, can provide longitudinal buffering when the screen is under force, weakening the direct impact of the impact on the main body of the screen, reducing the probability of screen damage, and extending the service life of the equipment.

[0012] The screen is hinged to a fixed shaft via a hinge block. With the support adjustment assembly driven by a hydraulic rod, the tilt angle of the screen can be flexibly adjusted. This design can meet the needs of different viewing distances (such as players in the near field viewing data and viewers in the far field viewing scores) and improve information transmission efficiency. The arc-shaped fixed tube and support rod of the support adjustment assembly are centered on the fixed shaft to ensure the stability of the screen's movement trajectory during adjustment.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-6This utility model provides a technical solution: an electronic sports field screen, including a base plate 1, which is shaped like a concave "U" and horizontally positioned. A fixed shaft 11 is installed at the front end of the top of the base plate 1, and sliding grooves 12 extending to the rear end are provided on both sides of the bottom of the base plate 1. Wheel grooves are provided at the two corners of the bottom front end of the base plate 1, and rotatable rollers 13 are provided in the two wheel grooves. Hinge blocks 21 are installed at the two corners of the bottom back of the screen body 2, and the two hinge blocks 21 are sleeved on the fixed shaft 11. Two sets of support adjustment components 3 are provided, and the two support adjustment components 3 are respectively located at the two corners of the top back of the screen body 2 and the two corners of the top rear end of the base plate 1. Between the two parts, the base 4 is provided with two sets of sliding grooves 12 that are slidably installed on the bottom of the base plate 1, and the bottom of the base 4 and the bottom of the roller 13 are at the same level. The U-shaped base plate 1, together with the front roller 13, not only ensures the stability of the equipment when placed horizontally, but also provides convenience for movement. The screen body 2 is connected to the fixed shaft 11 through the hinge block 21, so that the screen body 2 can be rotated and adjusted. The two sets of support adjustment components 3 provide stable support for the screen body 2 and assist in angle adjustment. The sliding cooperation between the base 4 and the sliding groove 12, combined with the design of the base 4 and the roller 13 being flush, not only ensures the overall stable placement of the equipment, but also lays the foundation for the subsequent buffer structure. The overall structure takes into account both stability and adjustability.

[0016] like Figure 2 , Figure 3 and Figure 4 As shown, the support adjustment assembly 3 includes a fixed tube 31, a support rod 32, a telescopic rod 33, a connecting block 351, and a connecting rod 352. Two fixed tubes 31 are provided and installed at the corner of the top rear end of the base plate 1. Two support rods 32 are provided, with their bottom ends movably inserted into the two fixed tubes 31 respectively. Two connecting blocks 351 are provided, and each connecting block 351 is installed at the top of one of the two support rods 32. The connecting rod 352 is fixedly connected between the two connecting blocks 351. Each top end of one of the two support rods 32 has a slot, and each of the two connecting blocks 351 has a corresponding insertion hole aligned with the slot. Two telescopic rods 33 are provided, with their bottom ends passing through the two insertion holes respectively. The two telescopic rods 33 are inserted into the corresponding slots, and the tops of the two telescopic rods 33 are fixedly connected to the back of the screen body 2. A second spring 34 is fixedly connected between the bottom of the two telescopic rods 33 and the inner end of the slot. Through the nested structure of the fixed tube 31, support rod 32 and telescopic rod 33, the support length can be flexibly adjusted to meet the support requirements of different tilt angles of the screen body 2. The design of the connecting block 351 and the connecting rod 352 connects the two sets of support rods 32 into a whole, improving the synchronization and stability of the support adjustment component 3. The second spring 34 at the bottom of the telescopic rod 33 and in the slot can provide longitudinal buffer when the screen body 2 is subjected to force, weaken the direct impact of the impact on the screen body 2, reduce the probability of damage to the screen body 2, and extend the service life of the equipment.

[0017] like Figure 1 and Figure 3 As shown, the support adjustment assembly 3 also includes a fixing member 36 and a hydraulic rod 37. The fixing member 36 is fixedly installed on the top of the base plate 1 and located between two fixing tubes 31. The bottom end of the hydraulic rod 37 is hinged to the fixing member 36, and the telescopic end of the hydraulic rod 37 is hinged to the connecting rod 352. The hydraulic rod 37 precisely controls the position of the connecting rod 352 by telescopic movement, thereby driving the support rod 32 and the telescopic rod 33 to adjust the angle of the screen body 2. Compared with manual adjustment, it is more labor-saving and efficient, and can accurately fix the angle of the screen body 2, meeting the precise needs of screen viewing angle in different viewing scenarios, and improving the ease of operation and adjustment accuracy.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the fixed tube 31, support rod 32, and telescopic rod 33 are all designed in an arc shape, and the center of the fixed tube 31, support rod 32, and telescopic rod 33 is on the same horizontal axis as the fixed shaft 11. This allows the support adjustment assembly 3 to move synchronously around the fixed shaft 11 when adjusting the angle of the screen body 2, ensuring that the movement trajectory of the screen body 2 is stable and smooth, avoiding jamming or deviation during the adjustment process, ensuring the stability of the angle adjustment of the screen body 2, and at the same time ensuring that the support adjustment assembly 3 always maintains a balanced support for the screen body 2, thus improving the overall structural stability of the equipment.

[0019] like Figure 2 , Figure 4 and Figure 5 As shown, sliders 121 are installed at the middle positions on both sides of the inner wall of the sliding groove 12. Positioning holes 1211 are provided on the sliders 121. The cross-section of the base 4 is "convex". Positioning rods 42 are installed at the top of the horizontal sections on both sides of the base 4. The positioning holes 1211 on the two sliders 121 inside the sliding groove 12 are respectively fitted onto the corresponding positioning rods 42 on the base 4. Countersunk holes 43 are provided at the four corners of the horizontal section of the base 4. Bolts 44 are inserted into each countersunk hole 43. Through the cooperation of the sliders 121, positioning holes 1211 and positioning rods 42, the sliding direction of the base 4 in the sliding groove 12 is precisely limited to prevent the base 4 from deviating or shaking when sliding, thus ensuring the overall stability of the equipment. The design of the countersunk holes 43 and bolts 44 makes it easy to fix the base 4 in a designated position on the ground, further enhancing the stability of the equipment after installation and preventing the equipment from being affected by accidental movement during use.

[0020] like Figure 2 , Figure 4 and Figure 5As shown, a fixing plate 14 is installed at the bottom of each of the two sliding grooves 12 near the roller 13. A rod groove 41 is opened at the end of each of the two bases 4 near the fixing plate 14. A guide rod 15 is installed at the fixing plate 14 of each of the two sliding grooves 12. The two guide rods 15 are respectively inserted into the corresponding rod grooves 41. A first spring 16 is sleeved on each of the two guide rods 15. The two ends of the first spring 16 are respectively connected to the fixing plate 14 and the base 4. When the equipment is impacted by an external force, the base 4 can slide slightly along the guide rod 15 in the sliding groove 12. The first spring 16 will extend and retract accordingly to absorb and mitigate the impact force, avoid the rigid transmission of the impact force causing the equipment to tip over, greatly reduce the risk of collisions to surrounding players and spectators, and significantly improve the safety of the equipment.
