Description

Technical Field

[0001] This utility model relates to the field of operation cards used in sports competitions or training, specifically to electronic substitution cards for football. Background Technology

[0002] As one of the most influential sporting events globally, football draws attention to every aspect of the match, with player substitutions being a crucial turning point that directly impacts the game's progress and outcome. In football, reasonable and timely substitutions can adjust team tactics, replenish player energy, and alter the game's tempo; therefore, ensuring the accuracy and efficiency of substitutions is paramount. In substitution operations, the substitution board is an indispensable tool, bearing the important responsibility of clearly conveying substitution information to the referee, both teams, and the spectators, namely, clearly displaying the numbers of the player being substituted off and the player coming on. However, most substitution boards widely used in football matches today are manual substitution boards that utilize numbered strips. For example, the "portable manual substitution board" disclosed in utility model patent application number 201110024991.9 mainly relies on manual insertion and removal of strips with different numbers to display player numbers. In actual use, when a substitution is required, staff must first accurately locate the strips corresponding to the numbers of the player being substituted and the player coming on from among numerous numbered strips, and then install them one by one in the corresponding positions on the substitution board. This process is not only cumbersome and time-consuming, but also, in the tense atmosphere of a match, staff can easily mistakenly pick the wrong numbered strip, leading to incorrect displayed number information. For example, the utility model patent with patent application number 201720605100.6 discloses a "football substitution board." Although it may have made some structural optimizations, it still essentially relies on manually replacing the number components to display and change the numbers. This method is not only inefficient, but also prone to problems such as insecure number installation and unclear display during rapid number switching, which can affect the accurate transmission of substitution information and even interfere with the fairness and smooth progress of the game. With the continuous development of football and the increasingly faster pace of matches, higher demands are placed on the timeliness and accuracy of substitutions. The drawbacks of traditional manual substitution boards—such as their cumbersome operation and susceptibility to errors—are becoming increasingly apparent, making them inadequate for the needs of modern football matches. Therefore, developing a football substitution board that is easy to operate, clearly displayed, and effectively improves substitution efficiency has become an urgent need in the current sports equipment industry. Utility Model Content

[0003] The purpose of this invention is to provide a football electronic substitution board that is easy to operate, has a clear display, and can effectively improve substitution efficiency.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a football electronic substitution board, comprising a front impact plate, a middle plate, a rear impact plate, a display module, and a control module. The front and rear impact plates are respectively distributed on the front and rear sides of the middle plate. The front, middle, and rear impact plates are stacked and fixed together to form the substitution board body. An installation cavity for embedding the display module is provided inside the substitution board body. The display module is embedded in the installation cavity of the substitution board body. The area of ​​the substitution board body corresponding to the display module is a transparent area. A control module mounting port is provided at the lower part of the substitution board body. The control module is embedded in the control module mounting port and installed on the substitution board body through a connecting mechanism. The control module is signal-connected to the display module to control the display module to display the numbers of players leaving the field and players entering the field.

[0005] Furthermore, in the aforementioned electronic substitution board for football, the control module includes a power supply unit, a control unit, and a key input unit. The power supply unit supplies power to the control unit and the display module. The control unit is simultaneously connected to the key input unit and the display module. The control unit can display the numbers of players leaving the field and players entering the field, which are input by the key input unit, on the display module.

[0006] Furthermore, in the aforementioned electronic substitution board for football, the front impact plate, the middle plate, and the rear impact plate are glued and fixed together to form the main body of the substitution board.

[0007] Furthermore, in the aforementioned electronic substitution board for football, an upper mounting slot is provided on the upper part of the middle plate, which runs through the middle plate from front to back. The parts of the front impact-resistant plate corresponding to the upper mounting slot and the parts of the rear impact-resistant plate corresponding to the upper mounting slot are closed, so that when the front impact-resistant plate, the middle plate and the rear impact-resistant plate are stacked in sequence, the upper mounting slot and the closed parts of the front impact-resistant plate and the rear impact-resistant plate corresponding to the upper mounting slot form a mounting cavity for the display module to be embedded.

[0008] Furthermore, in the aforementioned electronic substitution board for football, at least one of the closed portions of the front impact plate and the rear impact plate corresponding to the upper mounting slot is transparent, and the transparent closed portion constitutes the transparent area of ​​the corresponding display module on the substitution board body.

[0009] Furthermore, in the aforementioned electronic substitution board for football, the connecting mechanism includes a back plate and a front plate. The control module is installed on the front plate. The front plate and the back plate are located on the front and rear sides of the substitution board body, respectively. The front plate has several front mounting holes, the back plate has several rear mounting holes, and the substitution board body has several middle mounting holes. The front mounting holes, middle mounting holes, and rear mounting holes correspond one-to-one. Each corresponding front mounting hole, middle mounting hole, and rear mounting hole has a locking component. Each locking component can clamp the substitution board body between the back plate and the front plate in a front-to-back configuration, thereby installing the control module on the substitution board body.

[0010] Furthermore, in the aforementioned electronic substitution board for football, the locking assembly includes a male locking component and a female locking component. The female locking component consists of a nut body with internal threads and a positioning flange protruding from the outer wall of the nut body along its edge at one end. The male locking component consists of a screw that can be threaded into the nut body of the female locking component and a positioning head at one end of the screw. The nut body of the female locking component is aligned and sequentially inserted into the corresponding rear mounting hole, intermediate mounting hole, and front mounting hole until the positioning flange of the female locking component abuts against the back plate. The screw of the male locking component is aligned and screwed into the nut body of the female locking component until the positioning head of the male locking component abuts against the front plate, thereby clamping the substitution board body with the positioning head of the male locking component and the positioning flange of the female locking component in a front-to-back opposing position.

[0011] Furthermore, the aforementioned electronic substitution board for football also includes a holding part on the substitution board itself that makes it easy for people to hold the substitution board.

[0012] Through the implementation of the above technical solution, the beneficial effects of this utility model are: (1) The structure is simple and the assembly is convenient. Since the front and rear sides of the display module are equipped with protective impact plates, the probability of the display module being damaged by the impact is reduced, thereby extending the service life of the display module and thus extending the service life of the substitution card; (2) The operation is simple and convenient, saving time and effort. It is only necessary to use the key input unit of the control module to input the number of the player to be removed and the number of the player to be placed. The number of the player to be removed and the number of the player to be placed can be displayed quickly, clearly and accurately on the display module, so that the personnel in each area of ​​the field can quickly understand the number of the player to be removed and the number of the player to be placed, thereby effectively improving the substitution efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the electronic substitution board for football includes a front impact plate 1, a middle plate 2, a rear impact plate 3, a display module 4, and a control module 5. The front impact plate 1 and the rear impact plate 3 are respectively distributed on the front and rear sides of the middle plate 2. The front impact plate 1, the middle plate 2, and the rear impact plate 3 are stacked and fixed together to form the substitution board body 100. The substitution board body 100 is also provided with a holding part 6 for easy handling. Inside the substitution board body 100, there is a mounting cavity for the display module 4 to be embedded. The display module 4 is embedded in the mounting cavity of the substitution board body 100. The area of ​​the substitution board body corresponding to the display module 4 is a transparent area. A control module 5 is provided at the lower part of the substitution board body. The control module 5 is embedded in the control module mounting port 7 and installed on the substitution board body 100 through a connecting mechanism. The control module 5 is connected to the display screen module 4 via wiring 16, thereby controlling the display screen module 4 to display the numbers of players leaving the field and players entering the field. The control module 5 includes a power supply unit 51, a control unit 52, and a key input unit 53. The power supply unit 51 supplies power to the control unit 52 and the display screen module 4. The control unit 52 is connected to both the key input unit 53 and the display screen module 4. The control unit 52 can display the numbers of players leaving the field and players entering the field input by the key input unit 53 on the display screen module 4.

[0023] In this embodiment, the front impact plate 1, the middle plate 2 and the rear impact plate 3 are glued and fixed together to form the replacement card body 100. This fixing method can quickly complete the assembly of the replacement card body and is easy to operate.

[0024] In this embodiment, the mounting cavity is configured as follows: an upper mounting slot 8 is provided on the upper part of the middle plate 2, which runs through the middle plate 2 from front to back. The parts of the front impact plate corresponding to the upper mounting slot and the parts of the rear impact plate corresponding to the upper mounting slot are closed. When the front impact plate 1, the middle plate 2 and the rear impact plate 3 are stacked together in sequence, the upper mounting slot 8 and the closed parts of the front and rear impact plates corresponding to the upper mounting slots form a mounting cavity for the display module 4 to be embedded. This configuration can quickly form a mounting cavity for the display module 4 to be embedded when the front impact plate 1, the middle plate 2 and the rear impact plate 3 are stacked and fixed together, thereby improving the overall assembly efficiency of the card changer. In this embodiment, at least one of the closed portions of the front and rear impact-resistant plates corresponding to the upper mounting slot 8 is transparent. This transparent closed portion constitutes the transparent area of ​​the corresponding display screen module 4 on the substitution board body 100. In this embodiment, both the front and rear impact-resistant plates corresponding to the upper mounting slot 8 are transparent, so that the substitution board can display the numbers of the players leaving the field and the players entering the field on both sides, allowing spectators or players in all areas of the field to see the numbers of the players leaving the field and the players entering the field at the first moment, thereby improving substitution efficiency. In practical applications, the front impact-resistant plate 1, the middle plate 2, and the rear impact-resistant plate 3 are all made of transparent materials (such as transparent plastic).

[0025] In this embodiment, the control module mounting port 7 is configured as follows: a lower mounting slot 9 is provided at the lower part of the middle plate 2, which runs through the middle plate from front to back; a front slot 10 is provided at the lower part of the front impact-resistant plate 1; and a rear slot 11 is provided at the lower part of the rear impact-resistant plate 3. When the front impact-resistant plate 1, the middle plate 2, and the rear impact-resistant plate 3 are stacked and fixed together, the lower mounting slot 9, the front slot 10, and the rear slot 11 correspond to each other to form the control module mounting port 7, which facilitates the embedding of the control module 5. This configuration can quickly form the control module mounting port 7 for the embedding of the control module 5 when the front impact-resistant plate 1, the middle plate 2, and the rear impact-resistant plate 3 are stacked and fixed together, thereby improving the overall assembly efficiency of the replacement sign.

[0026] In this embodiment, as Figure 5 , Figure 6 , Figure 8As shown, the connecting mechanism includes a back plate 12 and a front plate 13. The control module 5 is installed on the front plate 13. The front plate 13 and the back plate 12 are located on the front and rear sides of the switch plate body 100, respectively. The front plate 13 has several front mounting holes, the back plate 12 has several rear mounting holes, and the switch plate body 100 has several middle mounting holes. The front mounting holes, middle mounting holes, and rear mounting holes correspond one-to-one. Each corresponding front mounting hole, middle mounting hole, and rear mounting hole is provided with a locking component. Each locking component can clamp the switch plate body 100 with the back plate 12 and the front plate 13 facing each other, thereby installing the control module 5 on the switch plate body 100. This connecting mechanism can not only install and fix the control module 5 on the switch plate body 100, but also clamp the switch plate body, so that the front impact plate 1, middle plate 2, and rear impact plate 3 constituting the switch plate body 100 will not separate or fall off, thereby improving the stability of the switch plate.

[0027] In this embodiment, the locking assembly includes a male locking component 14 and a female locking component 15. The female locking component 15 consists of a nut body 151 with internal threads 153 and a positioning flange 152 protruding from the outer wall of the nut body 151 along its edge at one end. The male locking component 14 consists of a screw 141 that can be threaded into the nut body 151 of the female locking component 15, and a positioning head 142 at one end of the screw 141. The nut bodies 151 of the female locking component 15 are aligned and sequentially... The locking pin 14 extends into the corresponding rear mounting hole, middle mounting hole, and front mounting hole until the positioning flange 152 of the locking pin 15 abuts against the back plate 12. The screw 141 of the locking pin 14 is aligned and screwed into the nut body 151 of the locking pin 15 until the positioning head 142 of the locking pin 14 presses against the front plate, thereby clamping the card changer body 100 with the positioning flange 152 of the locking pin 14 and the positioning head 142 of the locking pin 15 in a front-to-back relative position. The locking pin assembly has a simple structure, is easy to assemble, and can improve the overall assembly efficiency of the card changer.

[0028] During assembly, first, the rear impact-resistant plate 3 is glued and fixed to the back of the middle plate 2. At this time, the rear impact-resistant plate 3 and the upper mounting slot 8 of the middle plate 2 form a groove for the display module 4 to be inserted. Then, the display module 4 is inserted into the groove. Next, the front impact-resistant plate 1 is glued and fixed to the front of the middle plate 2, so that the front impact-resistant plate 1, the middle plate 2 and the rear impact-resistant plate 3 constitute the person-changing sign body 100. At this time, the display module 4 is embedded inside the person-changing sign body 100. Then, the control module 5 is aligned and inserted into the control module mounting port 7 of the person-changing sign body 100 until the front plate 13 is attached to the person-changing sign body 100. The front impact plate 1 of the 00 is aligned with the control module mounting port 7 and attached to the back of the rear impact plate 3 of the swap card body 100. The positions of the front plate 13 and the back plate 12 are adjusted so that the front mounting hole of the front plate 13, the middle mounting hole of the swap card body 100, and the rear mounting hole of the back plate 12 correspond one by one. Then, a locking assembly is set in each corresponding front mounting hole, middle mounting hole and rear mounting hole. The locking assembly is used to clamp the back plate 12 and the front plate 13 in a front-to-back position to clamp the swap card body 100, thereby installing the control module 5 on the swap card body 100. The installation process of the locking assembly is as follows: Align the nut body 151 of the locking female part 15 of the locking assembly and insert it into the corresponding rear mounting hole, middle mounting hole and front mounting hole in sequence until the positioning flange 152 of the locking female part 15 abuts against the back of the back plate 12. Then align the screw 141 of the locking male part 14 and screw it into the nut body 151 of the locking female part 15 until the positioning head 142 of the locking male part 14 abuts against the front of the front plate 13. Tighten the locking male part 14 so that the positioning head 142 of the locking male part 14 and the positioning flange 152 of the locking female part 15 clamp the person switch body 100 in a front-to-back relative position. Install the control module 5 on the person switch body 100 to complete the overall assembly of the person switch.

[0029] The advantages of this utility model are: (1) It has a simple structure and is easy to assemble. Since the front and rear sides of the display module are equipped with protective impact plates, the probability of the display module being damaged is reduced, thereby extending the service life of the display module and thus extending the service life of the substitution card; (2) It is simple and convenient to operate, saving time and effort. It is only necessary to use the key input unit of the control module to input the number of the player to be removed and the number of the player to be brought on. The number of the player to be removed and the number of the player to be brought on can be displayed quickly, clearly and accurately on the display module, so that the personnel in each area of ​​the field can quickly understand the number of the player to be removed and the number of the player to be brought on, thereby effectively improving the substitution efficiency.
