Description
Technical Field
[0001] The utility model relates to the technical field of blackboards, in particular to an infrared touch modification module and a blackboard. Background Art
[0002] At present, most blackboards on the market are equipped with capacitive screens. For example, the middle part is a capacitive screen, and the two sides of the capacitive screen are movable handwriting boards. The capacitive screen will inevitably be damaged after long-term use, and the price of the capacitive screen is very high. Customers cannot accept the high repair price, especially teaching institutions that often invest a huge number of blackboards in the early stage. Therefore, it is necessary to propose a low-cost and highly adaptable method to enable the touch screen to be used normally. Summary of the Invention
[0003] In order to solve the technical problem of high maintenance cost after the touch function of the blackboard in use in the prior art fails, the present application proposes an infrared touch modification module and a blackboard to solve the above technical problem.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] The utility model provides an infrared touch modification module, which includes at least one group of infrared touch frames, wherein one of the infrared touch frames is assembled on the top of an original capacitive touch screen, and the other infrared touch frame is assembled on the bottom of the original capacitive touch screen. The infrared emission surfaces of the two infrared touch frames in the same group protrude from the original capacitive touch screen and are arranged relative to each other, so as to form an infrared touch screen on the original capacitive touch screen.
[0006] Furthermore, the infrared touch frame located on the top of the original capacitive touch screen is detachably connected to the frame on the top of the original capacitive touch screen.
[0007] Furthermore, the infrared touch frame located on the top of the original capacitive touch screen is screwed onto the frame on the top of the original capacitive touch screen through a folding piece.
[0008] Furthermore, a card slot is opened on the infrared touch frame located at the bottom of the original capacitive touch screen, and the card slot cooperates with the convex strip at the bottom of the original capacitive touch screen. The infrared touch frame located at the bottom of the original capacitive touch screen is inserted into the bottom of the original capacitive touch screen along the extension direction of the convex strip to obtain support from the side strip at the bottom of the original capacitive touch screen.
[0009] Furthermore, the upward mounting surface of the infrared touch frame at the bottom of the original capacitive touch screen where the card slot is located is covered with double-sided tape so that the mounting surface fits the bottom of the original capacitive touch screen.
[0010] Furthermore, it also includes a fastening sheet metal part, which includes a supporting plate and a connecting plate connected to each other, the supporting plate is supported in a groove corresponding to the bottom of the infrared touch frame located at the bottom of the original capacitive touch screen, and the connecting plate is detachably connected to the bottom of the original capacitive touch screen.
[0011] Another aspect of the present invention further provides a blackboard, comprising the above-mentioned infrared touch modification module.
[0012] Based on the above technical solution, the technical effects that can be achieved by the present invention are:
[0013] The infrared touch modification module of the present invention changes the previous thinking of "repairing whatever is broken" and replaces the original capacitive touch with a lower-priced infrared touch. Specifically, infrared touch frames are assembled on the top and bottom of the original capacitive touch screen. The infrared emission surfaces of the two infrared touch frames in the same group protrude from the original capacitive touch screen and are arranged relative to each other to form an infrared touch screen on the original capacitive touch screen. The total cost is about 1 / 10-1 / 5 of replacing the capacitive screen (the cost of replacing the capacitive screen is about 3,000 yuan, and the cost of modifying it to infrared touch is several hundred yuan), thereby greatly reducing the maintenance cost and solving the technical problem of high maintenance cost after the failure of the blackboard touch function in the existing technology.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figure 1-6 As shown, the present invention provides an infrared touch modification module, including at least one group of infrared touch frames 1, wherein one infrared touch frame 1 is assembled on the top of the original capacitive touch screen 2, and the other infrared touch frame 1 is assembled on the bottom of the original capacitive touch screen 2, and the infrared emission surfaces 11 of the two infrared touch frames 1 in the same group protrude from the original capacitive touch screen 2 and are arranged relative to each other to form an infrared touch screen on the original capacitive touch screen 2.
[0023] The infrared touch modification module of the present invention changes the previous thinking of "repairing whatever is broken" and replaces the original capacitive touch with a lower-priced infrared touch. Specifically, an infrared touch frame 1 is assembled on the top and bottom of the original capacitive touch screen 2. The infrared emission surfaces 11 of the two infrared touch frames 1 in the same group protrude from the original capacitive touch screen 2 and are arranged relative to each other to form an infrared touch screen on the original capacitive touch screen 2. The total cost is about 1 / 10-1 / 5 of replacing a capacitive screen. For example, the cost of replacing a capacitive screen is about 3,000 yuan, while the cost of modifying it to an infrared touch screen is only a few hundred yuan, thereby greatly reducing the maintenance cost and solving the technical problem of high maintenance cost after the blackboard touch function that has been put into use in the prior art fails.
[0024] In practice, the infrared touch frame 1 located on top of the original capacitive touch screen 2 is detachably connected to the frame on top of the original capacitive touch screen 2. In a specific embodiment of the present invention, the infrared touch frame 1 located on top of the original capacitive touch screen 2 is screwed to the frame on top of the original capacitive touch screen 2 via a flange 3. This allows for quick and convenient installation of the infrared touch frame 1 located on top of the original capacitive touch screen 2 without having to disassemble the original blackboard assembly.
[0025] In practice, a slot 12 is provided on the infrared touch frame 1 located at the bottom of the original capacitive touch screen 2. The slot 12 cooperates with a ridge 21 at the bottom of the original capacitive touch screen 2. The infrared touch frame 1 located at the bottom of the original capacitive touch screen 2 is inserted into the bottom of the original capacitive touch screen 2 along the extension direction of the ridge 21, thereby being supported by the side bar 22 at the bottom of the original capacitive touch screen 2. The installation of the infrared touch frame 1 located at the bottom of the original capacitive touch screen 2 fully utilizes the bottom structure of the original capacitive touch screen 2, eliminating the need to disassemble the original blackboard components, making it convenient and quick.
[0026] Furthermore, the upward mounting surface 13 of the infrared touch frame 1 at the bottom of the original capacitive touch screen 2 where the card slot 12 is located is covered with double-sided tape to ensure that the mounting surface 13 fits the bottom of the original capacitive touch screen 2 .
[0027] Furthermore, a fastening sheet metal part 4 can be added, which includes a supporting plate 41 and a connecting plate 42 connected to each other. The supporting plate 41 is supported in a groove corresponding to the bottom of the infrared touch frame 1 located at the bottom of the original capacitive touch screen 2. The function of the groove is to prevent the side strip 22 and the supporting plate 41 from interfering with each other. The connecting plate 42 is detachably connected to the bottom of the original capacitive touch screen 2.
[0028] Another aspect of the present invention provides a blackboard, comprising the above-mentioned infrared touch modification module.
[0029] It should be understood that the specific embodiments described above are only used to explain the present invention and are not intended to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
