Description

Technical Field

[0001] This utility model relates to the field of capacitive screens, specifically a splicing capacitive screen. Background Technology

[0002] With the development of display technology, capacitive screens have been widely used in commercial displays, smart interactive terminals and other scenarios due to their sensitive touch and convenient operation. To meet the demand for large-size displays, splicing capacitive screens have gradually become the mainstream solution. By splicing multiple independent capacitive screen units together to form an integrated display surface, the display size can be flexibly adjusted and the production difficulty of a single screen can be reduced.

[0003] Currently, traditional capacitive screens are mostly installed individually, and their heat dissipation mainly relies on ventilation holes on the back or natural convection. Since the heat output of a single screen is limited and there is ample space behind it after installation, airflow is smooth, and heat can be quickly dissipated through the ventilation holes, meeting the heat dissipation requirements without the need for additional complex heat dissipation structures. However, in practical applications of spliced ​​capacitive screens, when multiple screen units are closely spliced ​​together, the backs of adjacent screens are almost completely flush, resulting in a significant compression of the overall back space and severely obstructing airflow. At the same time, the heat from multiple screen units is superimposed, causing the temperature in the back area to rise rapidly. At this point, relying solely on the screen's own ventilation holes is insufficient to meet the heat dissipation requirements. In spliced ​​scenarios, insufficient air convection makes it difficult for heat to dissipate effectively, easily causing heat accumulation. Being in a high-temperature environment for a long time will not only reduce the touch sensitivity of the capacitive screen, but also accelerate the aging of internal electronic components, shorten the lifespan of the device, and in severe cases, may even cause screen blackouts, touch failures, and other malfunctions. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a splicing capacitive screen to solve the technical problems of the back space being compressed and air circulation being obstructed due to the close splicing of multiple screen units, and the heat accumulation of multiple screens being unable to be effectively dissipated by relying solely on the screen's own heat dissipation holes, which in turn affects touch performance, accelerates the aging of electronic components, shortens the service life of the device, and even causes malfunctions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicing capacitive screen, including a screen and a mounting mechanism, wherein the mounting mechanism includes a first mounting frame and a second mounting frame, and two sets of heat dissipation mechanisms are installed on both sides of the first mounting frame and the second mounting frame by bolts; The heat dissipation mechanism includes a C-shaped frame, with spring sleeves fixed to the top and bottom of the inner side of the C-shaped frame. Each spring sleeve is fitted with a pin that can extend and retract along its axial direction, and a return spring is provided between the pin and the spring sleeve. Side mounting holes are correspondingly opened on the side of the first mounting frame and the side of the second mounting frame. The ends of the two pins away from the spring sleeves are respectively inserted into the side mounting holes of the first mounting frame and the second mounting frame. The C-shaped frame has multiple air guide sleeves arranged at equal intervals from top to bottom on one side wall facing the back of the screen, and each air guide sleeve has an electric fan fixed inside.

[0006] By adopting the above technical solution, the dual mounting brackets of the installation mechanism provide a stable mounting foundation for the screen, while the heat dissipation mechanisms mounted on both sides serve both fixing and heat dissipation functions. The spring sleeves, pins, and return springs of the heat dissipation mechanism work together to achieve quick insertion and positioning with the mounting brackets, and bolt reinforcement enhances reliability. The air guide sleeve fixes the electric fan to form a directional air guide structure, making heat dissipation more targeted. The overall structure balances installation stability and heat dissipation effectiveness.

[0007] Furthermore, the air outlet of the electric fan in one set of the heat dissipation mechanism is arranged facing the back of the screen to form an air guiding structure, while the air outlet of the electric fan in the other set of the heat dissipation mechanism is arranged away from the back of the screen to form an exhaust structure. The heat on the back of the screen is removed through the airflow circulation of the air guiding and exhaust.

[0008] By adopting the above technical solution, the fans of the two heat dissipation mechanisms are configured differently to form a directional airflow circulation. The air guide structure delivers airflow to the back of the screen, while the exhaust structure removes the hot airflow, allowing for rapid heat transfer. This structure specifically addresses the heat accumulation problem caused by multi-screen splicing, improving heat dissipation efficiency without the need for complex components and ensuring screen operational stability.

[0009] Furthermore, the screen includes a main body, one side of which is provided with a groove, and the other side of which is provided with a gusset, and multiple sets of the main body are mounted together through the groove and the gusset.

[0010] By adopting the above technical solution, the main screen is spliced ​​through a mounting structure with grooves and edges, allowing for initial positioning without the need for complex tools. This structure makes alignment during multi-screen splicing easier, ensuring tight connections between adjacent screens and effectively reducing splicing gaps. It also simplifies the splicing process, improves assembly efficiency, and guarantees the overall structural stability after splicing.

[0011] Furthermore, the outer surface of the groove is provided with magnetic card slots on the top and bottom, and the back of the edge is provided with magnetic card blocks on the top and bottom, and the magnetic card slots and magnetic card blocks are adapted to engage.

[0012] By adopting the above technical solution, a matching structure of magnetic slots and magnetic blocks is added to the existing slotting and edge-jointing layers, enhancing the splicing stability through magnetic attraction. Simultaneously, it assists in achieving precise alignment of the slots and edges, improving splicing accuracy. The magnetic structure is easy to assemble and disassemble without affecting splicing efficiency, and it also prevents loosening after splicing, strengthening the reliability of multi-screen connections.

[0013] Furthermore, both the first mounting bracket and the second mounting bracket are arranged in an L-shape, and the first mounting bracket and the second mounting bracket are respectively fixed to multiple spliced ​​screens by bolts.

[0014] By adopting the above technical solution, the L-shaped mounting bracket can fit snugly against the edge of the screen, increasing the contact area and improving stability. The overall structure, after multi-screen splicing, is secured with bolts, ensuring even stress distribution on the screen and preventing localized loosening. This structure is suitable for multi-screen splicing scenarios, is easy to install, and provides a reliable mounting foundation for the screen and heat dissipation mechanism.

[0015] Furthermore, the top and bottom of the first mounting bracket and the second mounting bracket are respectively provided with a plurality of equidistant side mounting holes.

[0016] By adopting the above technical solution, the multiple side mounting holes on the top and bottom of the mounting bracket provide multiple installation options for the heat dissipation mechanism. The spacing of the heat dissipation mechanism can be adjusted according to the screen size or heat dissipation requirements, improving adaptability. At the same time, it simplifies the installation and positioning process of the heat dissipation mechanism, ensures installation accuracy, and makes the heat dissipation layout more in line with actual heat dissipation needs.

[0017] Furthermore, a fixing mechanism is provided between the inner sides of the first mounting bracket and the second mounting bracket. The fixing mechanism includes a rotating seat, which is fixedly connected to the first mounting bracket and the second mounting bracket by bolts and nuts.

[0018] By adopting the above technical solution, the fixing mechanism located in the middle of the inner side is connected to the mounting bracket via a rotating seat. The bolt and nut fixing method ensures a firm connection that is not easily loosened. The rotating seat provides stable support for the subsequent angle adjustment structure, making the fixing mechanism and the mounting bracket an integrated structure, improving the overall installation reliability and adapting to wall installation requirements.

[0019] Furthermore, the inner side of the rotating seat is rotatably connected to a rotating connecting rod via a damping bearing, and the outer side of the rotating connecting rod is detachably connected to the wall fixing frame via a clamp, wherein the wall fixing frame is fixedly connected to the wall.

[0020] By adopting the above technical solutions, the damping bearing enables the flexible rotation of the rotating linkage, allowing the screen to be adjusted to a suitable angle and improving usability. The clamp connection method makes it easy to assemble and disassemble the rotating linkage from the wall mounting bracket, simplifying the maintenance process. The overall structure balances angle adjustment functionality with installation reliability, adapting to the needs of different usage scenarios.

[0021] In summary, the present invention has the following main advantages: 1. This utility model achieves convenient maintenance of splicing capacitive screens by setting up a heat dissipation mechanism. The C-shaped frame of the heat dissipation mechanism drives the pin through the return spring in the spring sleeve to form an elastic insertion engagement with the side mounting holes of the first mounting frame and the second mounting frame. Pressing the pin can quickly complete the separation or assembly of the heat dissipation mechanism and the mounting frame without disassembling a large number of bolts, which greatly shortens the disassembly and reassembly time during maintenance. It effectively solves the problem that traditional splicing capacitive screens require overall disassembly during maintenance due to their tightly fixed structure, which is cumbersome and time-consuming.

[0022] 2. This utility model significantly improves the heat dissipation performance of splicing capacitive screens by optimizing the layout and structure of the heat dissipation mechanism. Two sets of heat dissipation mechanisms are symmetrically distributed on both sides of the back of the screen. Each set of heat dissipation mechanisms has multiple air guide sleeves with electric fans fixed inside. The two sets of electric fans form an air guide structure facing the back of the screen and an exhaust structure away from the back of the screen, respectively. The two work together to form a directional and continuous airflow circulation on the back of the screen, which directly and quickly removes the superimposed heat generated by multi-screen splicing. At the same time, a heat dissipation gap is reserved between the heat dissipation mechanism and the back of the screen, avoiding the heat accumulation caused by the closed space on the back when splicing in traditionally. This effectively reduces the temperature of the back of the screen, ensures the touch sensitivity of the capacitive screen, delays the aging of internal electronic components, and extends the service life of the device.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1:

[0026] A type of splicing capacitive screen, such as Figure 1-4 As shown, it includes a screen 1 and a mounting mechanism 2. The mounting mechanism 2 includes a first mounting bracket 201 and a second mounting bracket 202. Two sets of heat dissipation mechanisms 4 are installed on both sides of the first mounting bracket 201 and the second mounting bracket 202 by bolts. The heat dissipation mechanism 4 includes a C-shaped frame 401. Spring sleeves 402 are fixed to the top and bottom of the inner side of the C-shaped frame 401 respectively. Each spring sleeve 402 is fitted with a pin 403 that can extend and retract along its axial direction. A return spring 406 is provided between the pin 403 and the spring sleeve 402. Side mounting holes 203 are opened on the side of the first mounting bracket 201 and the side of the second mounting bracket 202 respectively. The ends of the two pins 403 away from the spring sleeves 402 are respectively inserted into the side mounting holes 203 of the first mounting bracket 201 and the second mounting bracket 202. On one side wall of the C-shaped frame 401 facing the back of the screen 1, multiple air guide sleeves 404 are arranged equidistantly from top to bottom. Each air guide sleeve 404 contains a fixed electric fan 405. This structure achieves stable assembly through the cooperation of the screen 1 and the mounting mechanism 2. The first mounting bracket 201 and the second mounting bracket 202 of the mounting mechanism 2 form a symmetrical mounting frame, providing reliable support for the screen 1. Two sets of heat dissipation mechanisms 4 are installed on both sides by bolts, making the heat dissipation components and the mounting frame an integrated structure. The C-shaped frame 401 of the heat dissipation mechanism 4 serves as the load-bearing base. The spring sleeve 402, pin 403 and return spring 406 on its inner side form an elastic plug-in structure. Pressing the pin 403 can complete the docking or separation with the mounting hole 203 on the side of the mounting bracket. The connection reliability is further improved by bolt reinforcement. The air guide sleeves 404 of the C-shaped frame 401 facing the back of the screen 1 fix the electric fan 405, so that the airflow can be precisely applied to the heat dissipation area, solving the heat dissipation problem in splicing scenarios. The overall structure takes into account both installation convenience and targeted heat dissipation.

[0027] See Figure 3 , Figure 4One set of heat dissipation mechanisms 4 has its fan 405 outlet facing the back of the screen 1 to form an airflow guiding structure, while the other set of heat dissipation mechanisms 4 has its fan 405 outlet facing away from the back of the screen 1 to form an exhaust structure. The airflow circulation of the guiding and exhaust mechanisms removes heat from the back of the screen 1. This structure enhances heat dissipation through the functional differentiation of the two sets of heat dissipation mechanisms 4. Based on the basic structure of the heat dissipation mechanism 4 in claim 1, the two sets of heat dissipation mechanisms 4 have their fans 405 positioned with different orientations. One set of heat dissipation mechanisms 4 has its fan 405 outlet facing the back of the screen 1, forming a directional airflow guiding structure that can accurately deliver external cool air to the heat accumulation area on the back of the screen 1; the other set of heat dissipation mechanisms 4 has its fan 405 outlet facing away from the back of the screen 1, forming an exhaust structure that quickly exhausts the hot air after absorbing heat. The guiding and exhaust structures work together to form a complete airflow circulation, directly addressing the superimposed heat generated by multi-screen splicing. Efficient heat dissipation can be achieved without additional airflow ducts, avoiding the impact of high temperatures on screen touch performance and component lifespan. The structure is simple and highly targeted in heat dissipation. Example 2:

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The screen 1 includes a main body 101. A groove 102 is provided on one side of the main body 101, and an edge 103 is provided on the other side. Multiple main bodies 101 are mounted together via the groove 102 and the edge 103. This structure achieves convenient splicing through the structural design of the main body 101 itself. The groove 102 on one side of the main body 101 and the corresponding edge 103 on the other side allow adjacent main bodies 101 to be connected through the mounting of the edge 103 and the groove 102. The fitting structure of the groove 102 and the edge 103 enables rapid alignment during splicing, ensuring the installation accuracy of adjacent screens 1 without the need for external positioning tools, effectively reducing splicing gaps. This structure integrates the splicing function into the main body 101 of the screen 1, eliminating the need for additional splicing connectors, simplifying the assembly process of multi-screen splicing, and improving assembly efficiency. Meanwhile, the mounting of the slot 102 and the edge 103 can form a mechanical limit to prevent the screen 1 from shifting laterally after splicing, thus ensuring the overall structural stability of the multi-screen splicing.

[0029] See Figure 1 , Figure 2The outer surface of the slot 102 is provided with magnetic slots 104 on the top and bottom, and the back of the edge 103 is provided with magnetic blocks 105 on the top and bottom. The magnetic slots 104 and magnetic blocks 105 are adapted and engaged. This structure enhances the screen splicing effect through a dual structure of magnetic attraction and mechanical cooperation. Based on the slot 102 and edge 103 of claim 3, magnetic slots 104 are provided on the top and bottom of the outer surface of the slot 102, and magnetic blocks 105 are provided on the top and bottom of the back of the edge 103. During splicing, the edge 103 is mounted on the slot 102, and the magnetic blocks 105 and magnetic slots 104 are automatically adapted and engaged. The magnetic attraction force can make the two fit tightly together, enhancing the firmness of the splicing. The corresponding arrangement of the magnetic slots 104 and magnetic blocks 105 can also help the slot 102 and edge 103 achieve precise alignment, further improving the accuracy of multi-screen splicing and reducing splicing deviation. Compared to simple mechanical mounting, magnetic attachment can prevent the joints from loosening after long-term use, and only a certain amount of external force is needed to separate them during assembly and disassembly, without affecting the splicing efficiency, thus balancing connection reliability and ease of operation.

[0030] See Figure 1 , Figure 4 Both the first mounting bracket 201 and the second mounting bracket 202 are L-shaped structures, and multiple spliced ​​screens 1 are fixed to the first mounting bracket 201 and the second mounting bracket 202 by bolts. This structure improves installation reliability through the optimized shape design and fixing method of the mounting brackets. The L-shaped structure of the first mounting bracket 201 and the second mounting bracket 202 allows their inner sidewalls to fit snugly against the edge and back of the screen 1, increasing the contact area between the mounting bracket and the screen 1 and making the fixing force more evenly distributed to the screen 1. The spliced ​​multiple screens 1 are clamped between the first mounting bracket 201 and the second mounting bracket 202 and fixed by bolts. The bolt connection method is not only easy to operate, but also provides a stable clamping force to prevent the screens 1 from shifting or loosening during use. The L-shaped structure has strong adaptability and can accommodate the overall size of different numbers of spliced ​​screens, providing a symmetrical support base for the subsequent installation of the heat dissipation mechanism 4, so that the heat dissipation mechanism 4 can be stably assembled on both sides of the back of the screen 1. The overall structure provides reliable installation guarantee for the screens 1 and the heat dissipation components.

[0031] See Figure 1 , Figure 2The first mounting bracket 201 and the second mounting bracket 202 each have multiple equidistant side mounting holes 203 at their top and bottom. This structure improves the installation flexibility of the heat dissipation mechanism through the distribution design of the side mounting holes. The multiple equidistant side mounting holes 203 at their top and bottom adapt to the pins 403 of the heat dissipation mechanism 4. The multiple side mounting holes 203 allow the heat dissipation mechanism 4 to adjust its installation position according to the size of the screen 1, the distribution of heat-generating areas, or the number of panels. By selecting different side mounting holes 203 to connect with the pins 403, the spacing of the heat dissipation mechanism 4 can be flexibly adjusted, allowing the electric fan 405 inside the air guide sleeve 404 to accurately align with the heat accumulation area. Simultaneously, the multiple sets of mounting holes can serve as installation positioning references, simplifying the installation alignment process of the heat dissipation mechanism 4, ensuring the symmetrical distribution of the two heat dissipation mechanisms 4, guaranteeing the stability of airflow circulation, and improving the adaptability of the structure to different usage scenarios.

[0032] See Figure 1 , Figure 2 A fixing mechanism 3 is provided on the inner side of the first mounting bracket 201 and the second mounting bracket 202. The fixing mechanism 3 includes a rotating seat 301, which is fixedly connected to the first mounting bracket 201 and the second mounting bracket 202 by bolts and nuts. This structure provides a guarantee for the overall installation through the reliable connection between the fixing mechanism and the mounting bracket. The core component of the fixing mechanism 3, the rotating seat 301, is fixedly connected to the two mounting brackets by bolts and nuts. The bolts and nuts have reliable locking performance, which can firmly fix the rotating seat 301 to the mounting bracket, avoiding loosening of the connection due to vibration and other factors during long-term use, and providing a stable foundation for the subsequent function of the fixing mechanism 3. The installation position of the rotating seat 301 is located in the middle of the inner side, which can make the force of the fixing mechanism 3 evenly transmitted to the mounting bracket, and then distributed to the entire screen 1 structure, ensuring the stability of the overall installation. This connection method is easy to operate and can be adapted to the existing structure of the mounting bracket without requiring complex modifications to the mounting bracket, thus forming a stable integrated structure between the fixing mechanism 3 and the mounting bracket.

[0033] See Figure 1 , Figure 2The rotating base 301 has a rotating connecting rod 302 rotatably connected to its inner side via a damping bearing. The outer side of the rotating connecting rod 302 is detachably connected to the wall mounting bracket 303 via a clamp. The wall mounting bracket 303 is fixedly connected to the wall. This structure achieves angle adjustment and convenient assembly / disassembly through the cooperation of multiple components. The rotating base 301 of the fixing mechanism 3 is rotatably connected to the rotating connecting rod 302 via a damping bearing. The damping bearing provides stable damping force during rotation, allowing the rotating connecting rod 302 to be fixed at any angle, thereby adjusting the mounting bracket and screen 1 to a suitable usage angle and improving usability. The outer side of the rotating connecting rod 302 is connected to the wall mounting bracket 303 via a clamp. The detachable structure of the clamp allows for assembly / disassembly of the rotating connecting rod 302 and the wall mounting bracket 303 without complex tools, simplifying the installation and maintenance process. The fixed connection between the wall mounting bracket 303 and the wall provides reliable support for the overall structure. The combination of the rotational engagement of the damping bearing and the detachable design of the clamp not only enables flexible adjustment of the screen 1 angle but also ensures installation stability. At the same time, it facilitates the later maintenance of the screen 1 or the heat dissipation mechanism 4, taking into account both functional diversity and ease of operation.

[0034] The implementation principle of this embodiment is as follows: First, the main bodies 101 of multiple screens 1 are spliced ​​together. The overlapping edge 103 on one side of the main body 101 is engaged with the overlapping groove 102 on the other side of another main body 101. At the same time, the magnetic card block 105 on the back of the overlapping edge 103 is adapted and engaged with the magnetic card slot 104 on the outer surface of the overlapping groove 102 to complete the splicing and positioning of multiple screens. Then, the spliced ​​screens 1 are clamped and fixed by bolts using the first mounting bracket 201 and the second mounting bracket 202 with an L-shaped structure to achieve the installation limit of the screens 1. Next, install the heat dissipation mechanism 4, squeeze the pins 403 on the top and bottom of the inner side of the C-shaped frame 401 of the heat dissipation mechanism 4, so that the pins 403 compress the return spring 406 in the spring sleeve 402 and retract into the spring sleeve 402. Place the C-shaped frame 401 on both sides between the first mounting frame 201 and the second mounting frame 202, align the pins 403 with the side mounting holes 203 on the first mounting frame 201 and the second mounting frame 202, release the pins 403, and the return spring 406 resets and drives the pins 403 to engage with the side mounting holes 203. Then, further reinforce with bolts to make the two sets of heat dissipation mechanisms 4 stably installed on both sides of the back of the screen 1. Next, install the fixing mechanism 3, fix the rotating seat 301 to the middle of the inner side of the first mounting bracket 201 and the second mounting bracket 202 with bolts and nuts, rotate the rotating connecting rod 302 to the rotating seat 301 through the damping bearing, then disassemble and connect the rotating connecting rod 302 to the wall fixing bracket 303 through the clamp, and finally fix the wall fixing bracket 303 to the wall to complete the installation and fixing of the overall structure. In use, the electric fans 405 of the two sets of heat dissipation mechanisms 4 are activated. One set of electric fans 405 of the heat dissipation mechanism 4 forms an air guide structure to deliver airflow to the back of the screen 1, while the other set of electric fans 405 of the heat dissipation mechanism 4 forms an exhaust structure to exhaust airflow away from the back of the screen 1. Through the cooperation of air guide and exhaust, an airflow circulation is formed on the back of the screen 1, thereby removing the heat from the back of the screen 1. The angle of the rotating connecting rod 302 can be adjusted by the damping bearing, thereby adjusting the installation angle of the screen 1. When it is necessary to repair or replace the screen 1 and the heat dissipation mechanism 4, the heat dissipation mechanism 4 can be separated from the mounting bracket by pressing the pin 403 after removing the bolts. The rotating connecting rod 302 can be separated from the wall fixing bracket 303 by removing the clamps. The screen 1 can be removed by removing the bolts on the mounting bracket, realizing quick disassembly and maintenance.
