DETAILED DESCRIPTION

[0023] In order to make the technical scheme of the embodiments of the present application or the related art clearer, the accompanying drawings needed in the embodiments or the prior art description will be briefly introduced. Obviously, the accompanying drawings in the following description only need to explain the embodiments of the present application, and other drawings can be obtained by those skilled in the art without any creative effort.

[0024] Please refer to Figures 1-2 , the remote control display can include a remote control receiving device 1, the remote control receiving device 1 includes a remote control receiving device 10 and a circuit board 20, wherein the remote control receiving device 10 can transmit the received signal to the controller (not shown in the figure) on the circuit board 20 after processing, and the controller can control the remote control display to perform corresponding operation according to the received signal, therefore, the remote control receiving device 10 needs to be assembled to the circuit board 20.

[0025] In the related art, the pin 12 of the remote control receiving device 10 needs to be bent before the remote control receiving device 10 is connected with the circuit board 20. It can be understood that before the remote control receiving device 10 is installed on the circuit board 20, the worker needs to bend the pin 12 by hand or machine, and manually insert the processed pin 12 on the circuit board 20 to realize the installation of the remote control receiving device 10 on the circuit board 20. However, such an assembly process not only increases the labor cost, but also makes the assembly process of the remote control receiving device 10 on the circuit board 20 slow, thereby reducing the production efficiency.

[0026] Please continue to refer to Figures 1-2 Therefore, in order to solve the above problems, the embodiment of the application sets the mounting surface 21 of the circuit board 20 to have the positioning hole 22 and the solder pad 23 arranged at intervals, wherein part of the remote control receiving device 10 is installed in the positioning hole 22, so that the pin 12 of the remote control receiving device 10 is located above the mounting surface 21. In this way, the pin 12 of the remote control receiving device 10 can be positioned on the circuit board 20, and the pin 12 of the remote control receiving device 10 is connected with the solder pad 23 by patching, so as to improve the production efficiency. Furthermore, the pin 12 of the remote control receiving device 10 does not need to be bent before the remote control receiving device 10 is installed on the circuit board 20, so as to reduce the labor cost.

[0027] The embodiment of the application provides a remote control display. The remote control display is a display which can be controlled by a remote controller or an infrared pen. The remote control display allows a user to perform various operations on the display by using the remote controller or the infrared pen, such as controlling the on-off of the display, controlling the volume adjustment of the display, and the like. The remote control display can include one of existing displays, such as a commercial display, an interactive flat panel display (IFPD), a multi-screen display, and the like, and the embodiment of the application does not make a specific limitation thereon.

[0028] Further, the remote control display can include a shell and a remote control receiving device 1. The shell is internally provided with a mounting space, and the remote control receiving device 1 is mounted in the mounting space. In this way, the shell plays a role of protecting the remote control receiving device 1, and prevents the remote control receiving device 1 from being damaged.

[0029] The shell of the remote control display is usually made of plastic, metal or other composite materials. The embodiments of the present application do not make specific limitations on this. Exemplarily, common plastic materials used to make the shell include ABS material, PC material and PVC material, etc., which have good insulation, corrosion resistance and low cost and are widely used to prepare the shell of the remote control display; the metal shell can include aluminum alloy, stainless steel, etc., and the metal shell has good heat dissipation performance and high mechanical strength.

[0030] The remote control receiving device 1 will be described in detail below.

[0031] Please continue to refer to Figures 1-2 , the remote control receiving device 1 includes a remote control receiving device 10 and a circuit board 20.

[0032] Specifically, the remote control receiving device 10 includes a receiving body 11 and a pin 12 connected to each other, the receiving body 11 is used to receive the infrared signal emitted by the remote controller or the infrared pen, and the pin 12 is used to be connected with the circuit board 20. It can be understood that the receiving body 11 and the pin 12 can be connected by welding to fix one end of the pin 12 on the receiving body 11, and the receiving body 11 and the pin 12 are connected by welding, which can ensure the stability of the connection between the pin 12 and the receiving body 11, and can ensure the normal conduction of current and the accurate transmission of signal.

[0033] Please refer to Figures 2-3 , the circuit board 20 has a mounting surface 21, the mounting surface 21 has a positioning hole 22 and a solder pad 23 arranged at intervals, wherein part of the receiving body 11 is mounted in the positioning hole 22 to position the pin 12 on the solder pad 23, and the pin 12 is connected to the solder pad 23 by patching. It can be understood that during the assembly of the remote control receiving device 1, the assembly production line can include mechanical components, wherein the mechanical components can be grabbing mechanical arms or suction mechanical arms, and the embodiments of the present application do not make specific limitations on this. The mechanical components can grab or suck the remote control receiving device 10 and move the remote control receiving device 10, so that the remote control receiving device 10 moves above the positioning hole 22, and part of the receiving body 11 of the remote control receiving device 10 is in the positioning hole 22, while the pin 12 connected with the receiving body 11 is outside the positioning hole 22, so that the pin 12 is positioned on the solder pad 23; at the same time, the pin 12 is connected to the solder pad 23 by patching, so that the remote control receiving device 10 is mounted on the circuit board 20, thereby realizing the signal transmission between the remote control receiving device 10 and the circuit board 20.

[0034] According to the above, the pin 12 and the pad 23 can be connected by patching, meeting the technical requirements of surface mounted technology (SMT). SMT is a circuit assembly technology that installs surface-mounted components (such as the remote control receiving device 10) with short leads on the mounting surface 21 of the circuit board 20 and welds them by reflow soldering or immersion soldering. At the same time, mechanical parts are used to move and install the remote control receiving device 10, which can improve production efficiency. Furthermore, compared with the related art, which requires workers to bend the pin 12 before assembling the remote control receiving device 1, the embodiment of the present application does not require workers to bend the pin 12 before assembling the remote control receiving device 1, thereby reducing labor costs.

[0035] In addition, in the related art, when workers bend the pin 12, the force of the workers bending the pin 12 is inconsistent, so there is a risk that the remote control receiving device 10 will fail due to the large stress on the pin 12, and the plating layer at the bent part of the pin 12 will be damaged. This can cause the pin 12 to rust after the remote control receiving device 1 is used for a period of time, resulting in a shortened service life of the remote control receiving device 1 and increased replacement costs. The embodiment of the present application does not require bending the pin 12, thereby avoiding rusting of the pin 12 and prolonging the service life of the remote control receiving device 1.

[0036] It should be noted that the size of the positioning hole 22 is related to the size of the remote control receiving device 10, and the size of the positioning hole 22 is not limited in the embodiment of the present application.

[0037] It should be noted that the positioning hole 22 can completely penetrate the circuit board 20 in the thickness direction BB of the circuit board 20 (as shown in Figure 2 The present embodiment does not make specific limitations on this.

[0038] Please refer to Figure 2 For example, the positioning hole 22 completely penetrates the circuit board 20 in the thickness direction BB of the circuit board 20, so that the remote control receiving device 10 can be cooled when it is working and part of it is installed in the positioning hole 22.

[0039] Please refer to Figure 1 and Figure 4In some embodiments, the number of pins 12 can be three, and the three pins 12 are arranged in the first direction AA with intervals, that is, each pin 12 has a gap in the first direction AA to avoid the welding overlap between the pins 12 when the pins 12 are connected to the pads 23 by patching. The first direction AA can be understood as the width direction of the receiving body 11.

[0040] For further reference Figure 1 and Figure 4 Further, the three pins 12 include a first pin 121 in the middle and two second pins 122 respectively on both sides of the first pin 121, wherein at least a part of at least one second pin 122 extends away from the first pin 121. It can be understood that a part of one second pin 122 extends away from the first pin 121, or a part of the other second pin 122 extends away from the first pin 121, or a part of both second pins 122 extends away from the first pin 121, to avoid the welding overlap between the first pin 121 and the at least one second pin 122, so as to ensure that the remote control receiving device 10 and the circuit board 20 can normally transmit.

[0041] For further reference Figure 4 In some embodiments, the second pin 122 includes a connecting segment 1221, an extending segment 1222, and a welding segment 1223.

[0042] Specifically, one end of the connecting segment 1221 is connected to the receiving body 11, and the other end of the connecting segment 1221 is connected to the extending segment 1222; the extending segment 1222 extends away from the first pin 121; the welding segment 1223 is connected to one end of the extending segment 1222 away from the first pin 121; that is, the extending segment 1222 in the second pin 122 extends away from the first pin 121 to increase the distance between the extending segment 1222 and the welding segment 1223 and the first pin 121 in the first direction AA, thereby avoiding the welding overlap between the first pin 121 and the welding segment 1223 of the second pin 122.

[0043] Further, the connecting segment 1221, the extending segment 1222, and the welding segment 1223 are attached to the mounting surface 21. It can be understood that when a part of the receiving body 11 is mounted in the positioning hole 22, the pin 12 is not mounted in the positioning hole 22, so that the connecting segment 1221, the extending segment 1222, and the welding segment 1223 are attached to the mounting surface 21, thereby positioning the welding segment 1223 on the welding pad and connecting the welding segment 1223 to the pad 23 by patching, so as to improve the stability of the connection between the pin 12 and the pad 23.

[0044] Further, in some embodiments, the first pin 121 is a ground pin, one of the second pins 122 is a power pin, and the other second pin 122 is an output pin. It can be understood that the power pin is a power input pin of the remote control receiving device 10, which is responsible for providing the required operating voltage, and the operating voltage depends on the specifications and circuit design of the remote control receiving device 10, which is not limited in the embodiments of the present application; the ground pin is a ground pin of the remote control receiving device 10, which is connected to the ground of the circuit of the circuit board 20 to ensure that the remote control receiving device 10 has stable power supply and signal; the output pin is an output pin of the remote control receiving device 10, and the output pin is used to output the received signal, that is, when the remote control receiving device 10 detects a signal, the output pin can generate a corresponding level change to transmit the signal to the controller connected to the circuit board 20, at this time, the controller can control the remote display to perform the corresponding operation according to the received signal.

[0045] In other embodiments, the soldering section 1223 is provided with solder towards the surface of the mounting surface 21 (not shown in the figure), which is used to solder the soldering section 1223 with the solder pad 23. It can be understood that when the pin 12 is connected with the solder pad 23 by patching, the solder is a process of connecting the solder material together with the pin 12 by heating and melting, so that the pin 12 is firmly connected with the solder pad 23 on the circuit board 20 to form an electrical path, thereby ensuring that the signal received by the remote control receiving device 10 can be accurately and stably transmitted.

[0046] It should be noted that in the electronic industry, the method of soldering can include electronic soldering, immersion soldering, wave soldering, etc. The present application does not limit the method of soldering.

[0047] Please refer to Figure 1 and Figure 4 In still other embodiments, the soldering section 1223 is provided with solder towards the surface of the mounting surface 21, which is used to solder the soldering section 1223 with the solder pad 23; at the same time, the first pin 121 is a ground pin, one of the second pins 122 is a power pin, and the other second pin 122 is an output pin; that is, the first pin 121 and the two second pins 122 need to be accurately connected to the corresponding positions of the solder pad 23 to ensure that the first pin 121 and the two second pins 122 are correctly connected with the solder pad 23 of the circuit board 20, so that on the one hand, the remote control receiving device 10 is provided with appropriate power supply, and on the other hand, the normal signal transmission between the remote control receiving device 10 and the controller of the circuit board 20 is ensured.

[0048] Please refer to Figure 1In some embodiments, the width of the positioning hole 22 is greater than or equal to the width of the receiving body 11 in the first direction AA. That is, when the mechanical component picks up or sucks the remote receiving device 10, the width of the positioning hole 22 is greater than or equal to the width of the receiving body 11, so that part of the receiving body 11 is mounted in the positioning hole 22. For example, the width of the positioning hole 22 is greater than the width of the receiving body 11, at this time, the receiving body 11 has a gap with the hole wall of the positioning hole 22 in the first direction AA, which can ensure the heat dissipation performance of the receiving body 11 when the remote receiving device 10 is working.

[0049] Please refer to Figures 4-5 Further, in some embodiments, the receiving body 11 includes a positioning part 111 and a receiving part 112.

[0050] Specifically, part of the positioning part 111 is positioned in the positioning hole 22, and the positioning part 111 is connected with the pin 12; it can be understood that since the pin 12 needs to be connected with the pad 23, the pin 12 is connected with the part of the positioning part 111 which is not positioned in the positioning hole 22, so that the pin 12 is attached on the mounting surface 21 as a whole.

[0051] The receiving part 112 is connected with the positioning part 111, and the receiving part 112 has a signal receiving window, which is responsible for receiving signals emitted from a remote controller or an infrared pen and converting the signals into electrical signals for identification by a controller; wherein the signal receiving window of the receiving part 112 is located on the side of the mounting surface 21 of the circuit board 20, that is, the signal receiving window faces away from the positioning hole 22, so as to ensure that the signal receiving window can accurately receive the signals emitted from the remote controller or the infrared pen.

[0052] It should be noted that the positioning part 111 and the receiving part 112 are integrated components, so on the one hand, the process of assembling the receiving body 11 is saved, so as to improve the production efficiency; on the other hand, the stability of the connection between the positioning part 111 and the receiving part 112 can be improved. Of course, in other embodiments, the positioning part 111 and the receiving part 112 can be connected by welding, magnetic attraction or the like.

[0053] Please continue to refer to Figures 4-5 In some embodiments, the positioning part 111 can include a main body sub-part 1111 and an embedded sub-part 1112.

[0054] Specifically, the main body sub-part 1111 is connected with the receiving part 112, so that the main body sub-part 1111 can bear the receiving part 112; the main body sub-part 1111 is located outside the positioning hole 22 and on the side of the mounting surface 21 of the circuit board 20, at this time, the pin 12 is connected with the main body sub-part 1111, so as to attach the pin 12 on the mounting surface 21.

[0055] The embedded sub-portion 1112 is connected to the side of the main body sub-portion 1111 which is away from the receiving portion 112, and the embedded sub-portion 1112 is embedded into the positioning hole 22, so as to realize that part of the receiving body 11 is installed into the positioning hole 22. Further, a step structure 1113 is arranged between the embedded sub-portion 1112 and the main body sub-portion 1111, wherein the step structure 1113 is connected to the mounting surface 21. It can be understood that, in order to facilitate the embedded sub-portion 1112 to be embedded into the positioning hole 22, the step structure 1113 is arranged between the embedded sub-portion 1112 and the main body sub-portion 1111, so as to realize that part of the receiving body 11 is installed into the positioning hole 22, and at the same time, the step structure 1113 is connected to the mounting surface 21, so as to realize the positioning of the receiving body 11, thereby facilitating the positioning of the pin 12 to the pad 23 of the circuit board 20.

[0056] It should be noted that the side of the embedded sub-portion 1112 and the main body sub-portion 1111 which is away from the receiving portion 112 can be integrally formed by injection molding, so as to improve the stability of the connection between the embedded sub-portion 1112 and the main body sub-portion 1111. Of course, in other embodiments, the side of the embedded sub-portion 1112 and the main body sub-portion 1111 which is away from the receiving portion 112 can be connected by welding, magnetic attraction or the like.

[0057] Please refer to Figure 1 In some embodiments, the circuit board 20 is provided with a copper foil 24. It can be understood that the copper foil 24 is part of the copper foil on the circuit board 20, and the copper foil 24 is usually protruded on the mounting surface 21 of the circuit board 20, and the copper foil is a soft metal sheet mainly made of pure copper and has good electrical conductivity and heat dissipation. Further, the copper foil 24 is connected to the pad 23, and the pad 23 is connected to the pin 12 patch, so as to form a conductive path between the pin 12 and the circuit board 20, thereby facilitating the signal transmission between the remote control receiving device 10 and the controller on the circuit board 20.

[0058] Please refer to Figures 1-2 In other embodiments, the circuit board 20 is provided with a copper foil 24, and the copper foil 24 is connected to the pad 23, and at the same time, the positioning hole 22 penetrates the circuit board 20 in the thickness direction BB of the circuit board 20, so that on the one hand, the pad 23 is connected to the pin 12 patch, and on the other hand, when part of the receiving body 11 is embedded into the positioning hole 22, because the positioning hole 22 penetrates the circuit board 20 in the thickness direction BB of the circuit board 20, the receiving body 11 embedded into the positioning hole 22 is not blocked by the side away from the mounting surface 21, thereby improving the heat dissipation performance of the remote control receiving device 10.
