Description

Technical Field

[0001] This utility model relates to the field of LED billboard technology, and in particular to an LED billboard for buses that is easy to fix. Background Technology

[0002] LED billboards on buses are a common form of outdoor advertising, using LED displays to show advertisements on buses. LED displays can show dynamic videos, images, and text, attracting more attention and enhancing the appeal of advertisements compared to static ones. Bus routes typically cover various areas of a city, allowing advertisements to reach target audiences in different regions. The advertising content can be updated at any time, adjusting the displayed content according to market changes and marketing strategies.

[0003] Most existing LED billboards are bolted to buses, which makes it very inconvenient to inspect or replace them. This can also cause the billboards to loosen or fall off while the bus is in motion, posing a safety hazard. Most billboards also lack shock-absorbing structures. Buses encounter various road conditions such as bumps and sudden braking. Without shock-absorbing structures, the billboards may loosen or even fall off due to vibrations, creating a safety hazard.

[0004] Therefore, those skilled in the art have provided an easy-to-fix LED advertising board for buses to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a conveniently fixed LED advertising board for buses. This advertising board allows for quick assembly and disassembly of the advertising screen, making it easy to use. Furthermore, a shock-absorbing frame is installed between the vehicle's internal support and the advertising screen to reduce the impact of vibration on the advertising board and extend its service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An easy-to-fix LED advertising board for buses includes an advertising screen, a bracket, and two shock-absorbing frames. The advertising screen includes an LED screen body. Inserts are fixedly installed on both sides of the rear end of the LED screen body near the top. A first inner groove is opened in the middle of the two inserts. Two first springs are fixedly installed on the front inner wall of the two first inner grooves. The four first springs are paired up and each has a plug fixedly installed at the rear end. A slot is opened at the upper end of each of the two plugs.

[0008] The shock absorber includes a fixed frame and two fixed blocks. Limiting rods are fixedly installed on the upper and lower sides of the inner walls of the front and rear sides of the fixed frame. Spring No. 2 is fixedly installed at both ends of the two fixed blocks. Telescopic rods are hinged to one side of each of the two fixed blocks. Spring No. 3 is movably sleeved around the entire body of each of the two telescopic rods. Connecting frame is hinged to one side of each of the two telescopic rods. A sliding groove is opened at the upper front end of the connecting frame. A second inner groove is opened in the middle of the inner wall of the rear side of the sliding groove. A slot is opened at the lower front inner wall of the second inner groove. Spring No. 4 is fixedly installed on the bottom surface of the inner groove of the second inner groove. A push block is fixedly installed on the upper end of the fourth spring. A hook-shaped block is fixedly installed on the rear side of the upper end of the push block.

[0009] Furthermore, the two shock-absorbing frames are respectively fixedly sleeved on both sides of the support, and the advertising screen is set between the two shock-absorbing frames.

[0010] Furthermore, a protective cover is fixedly installed on the front side of the LED screen body, and the protective cover is made of transparent acrylic material.

[0011] Furthermore, a through groove is provided on the rear inner wall of the second inner groove, a sliding plate is hinged to the rear end of the push block, and a groove is provided on the rear side of the connecting frame near the lower part of the through groove.

[0012] Furthermore, the two limiting rods are movably sleeved with the two fixing blocks respectively, and the four second springs are movably sleeved with the two limiting rods respectively, with the opposite ends of the four second springs being fixedly connected to the inner walls of the front and rear sides of the fixing frame respectively.

[0013] Furthermore, an elastic cloth is fixedly sleeved on one side inside the fixed frame, and the elastic cloth and the connecting frame are fixedly sleeved together.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes an easy-to-fix LED advertising board for buses. By setting a connecting frame in two shock-absorbing frames, during installation, two inserts on the back side of the advertising screen are inserted into the sliding grooves on the front side of the two connecting frames. Since the lower side of the insert is set as an inclined surface, the insert is squeezed into the first inner groove as the insert moves down until it aligns with the slot and is inserted into the slot. At the same time, when the insert is inserted into the slot, it will squeeze the hook-shaped block, so that the locking block of the hook-shaped block is inserted into the slot for double fixation, so that the advertising screen is stably fixed between the two shock-absorbing frames. During disassembly, it is only necessary to open the sliding plate to drive the push block to move upward. The locking block of the hook-shaped block moves out of the slot and squeezes the insert, so that the insert is pushed into the first inner groove, so that the advertising screen can be directly removed from between the two shock-absorbing frames, which facilitates quick assembly and disassembly of the advertising board.

[0016] 2. This utility model proposes an easy-to-fix LED advertising board for buses. The advertising board has two shock-absorbing frames installed on both sides of the advertising screen and between the support frame. A telescopic rod is installed between the inner wall of the fixed frame of the shock-absorbing frame and the connecting frame. A No. 3 spring is movably sleeved around the telescopic rod, which can absorb the shock of the advertising screen between the two connecting frames when the bus is bumpy. The fixed block hinged to the telescopic rod is slidably installed around the limiting rod, and a No. 2 spring is installed at both the front and rear ends of the fixed block. This allows the connecting frame to have space to move back and forth, thereby absorbing the shock of the advertising screen, reducing the impact of vibration on the advertising board, and extending its service life.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2 One embodiment provided by this utility model:

[0030] An easy-to-fix LED advertising board for buses includes an advertising screen 1, a bracket 2, and two shock-absorbing frames 3. The two shock-absorbing frames 3 are fixedly fitted to both sides of the bracket 2, and the advertising screen 1 is set between the two shock-absorbing frames 3.

[0031] Specifically, the two shock-absorbing frames 3 are fixed by the bracket 2, and the two shock-absorbing frames 3 support the advertising screen 1 and at the same time reduce the shock of the advertising screen 1.

[0032] Reference Figure 3 , Figure 4 , Figure 5 The advertising screen 1 includes an LED screen body 101. Inserts 103 are fixedly installed on both sides of the upper rear end of the LED screen body 101. An inner groove 105 is opened in the middle of the two inserts 103. Two springs 106 are fixedly installed on the inner front wall of the two inner grooves 105. The four springs 106 are arranged in pairs and each has a block 104 fixedly installed at the rear end. A slot 107 is opened at the upper end of each of the two blocks 104. A protective cover 102 is fixedly installed on the front side of the LED screen body 101. The protective cover 102 is made of transparent acrylic material.

[0033] Specifically, insert strips 103 are fixedly installed on the upper sides of the rear end of the LED screen body 101. The insert strips 103 are convex structures, so that the insert strips 103 can slide into the slide grooves 304 to fix the advertising screen 1 between the two shock-absorbing frames 3. An inner groove 105 is opened inside the insert strip 103, and a spring 106 is set inside the inner groove 105. The tension of the spring 106 pushes the insert block 104 backward, so that the insert block 104 maintains a backward force. After the insert block 104 is pushed into the inner groove 105, it can be released to reset. A slot 107 is opened on the upper side of the insert block 104. The hook block 316 can be inserted into the slot 107 to lock and limit the insertion block 104. The front side of the LED screen body 101 can be protected by setting a protective cover 102.

[0034] Reference Figures 5-9 The shock absorber 3 includes a fixed frame 301 and two fixed blocks 306. Limit rods 307 are fixedly installed on the upper and lower sides of the inner walls of the front and rear sides of the fixed frame 301. Two springs 308 are fixedly installed at the front and rear ends of the two fixed blocks 306. Telescopic rods 310 are hinged to one side of the two fixed blocks 306. Three springs 309 are movably sleeved around the two telescopic rods 310. A connecting frame 303 is hinged to one side of the two telescopic rods 310. A sliding groove 304 is opened at the upper front end of the connecting frame 303. A second inner groove 305 is opened in the middle of the inner wall of the rear side of the sliding groove 304. A slot 317 is opened at the lower front inner wall of the second inner groove 305. A fourth spring 312 is fixedly installed on the bottom surface of the inner wall of the second inner groove 305. A push block 313 is fixedly installed on the upper end of the fourth spring 312. A hook block 316 is fixedly installed on the rear side of the upper end of the push block 313.

[0035] A through groove 314 is provided on the rear inner wall of the second inner groove 305. A sliding plate 315 is hinged to the rear end of the push block 313. A groove 311 is provided on the rear side of the connecting frame 303 near the lower side of the through groove 314. Two limiting rods 307 are movably sleeved with two fixing blocks 306 respectively. Four second springs 308 are movably sleeved with two limiting rods 307 respectively. The four second springs 308 are paired up in pairs with opposite ends and fixedly connected to the front and rear inner walls of the fixing frame 301 respectively. An elastic cloth 302 is fixedly sleeved on one side inside the fixing frame 301. The elastic cloth 302 and the connecting frame 303 are fixedly sleeved.

[0036] Specifically, the fixed block 306 can be supported by the limiting rod 307, and the fixed block 306 can slide on the limiting rod 307. When the bus accelerates or brakes, it can reduce the shock in the front and back directions of the advertising screen 1. The advertising screen 1 can be reduced in the left and right directions by setting the telescopic rod 310 and the No. 3 spring 309 is movably sleeved around the telescopic rod 310. The advertising screen 1 can be reduced in the left and right directions by setting the elastic cloth 302 between the connecting frame 303 and the fixed frame 301. Due to the elasticity of the elastic cloth 302 itself, the elastic cloth 302 can deform when relative displacement occurs between the fixed frame 301 and the connecting frame 303, and can also prevent garbage and debris from being stuffed into the fixed frame 301.

[0037] By opening a groove 304 on the front side of the connecting frame 303, the groove 304 fits the shape of the insert 103, allowing the insert 103 to slide into the groove 304. A fourth spring 312 and a push block 313 are provided in the second inner groove 305. Since the lower side of the insert 104 is set as an inclined surface, the insert 104 can be squeezed by pushing the push block 313, so that the insert 104 enters the first inner groove 105, thereby allowing the advertising screen 1 to be removed from the two shock-absorbing frames 3. By setting a sliding plate 315, it can be opened and moved upward, thereby allowing the push block 313 to move upward. After installation, the sliding plate 315 can be rotated into the groove 311 to store the sliding plate 315 and also limit the push block 313.

[0038] Working principle: During installation, the advertising screen 1 is installed by inserting two inserts 103 on the rear side into the sliding grooves 304 on the front side of the two connecting brackets 303. Since the lower side of the insert 104 is set as an incline, the insert 104 is squeezed into the first inner groove 105 as the insert 103 moves down, until it aligns with the slot 317 and inserts into the slot 317. At the same time, when the insert 104 is inserted into the slot 317, it will squeeze the hook block 316, causing the locking part of the hook block 316 to be inserted. The card slot 107 is double-fixed. When disassembling, simply open the sliding plate 315 from the groove 311, and then push the sliding plate 315 upward to move the push block 313 upward. When the push block 313 moves upward, the hook block 316 will move out of the card slot 107. At the same time, the push block 313 pushes the insert block 104 upward, so that the insert block 104 is squeezed into the first inner groove 105, thereby moving the advertising screen 1 upward and removing the two inserts 103 from the sliding groove 304, thereby disassembling the advertising screen 1.

[0039] Secondly, two shock-absorbing frames 3 are installed between the advertising screen 1 and the support 2. If vibration occurs when the bus moves, the advertising screen 1 can be buffered and its service life extended.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
