Description

Technical Field

[0001] This invention relates to the technical field of remote control testing device improvement, and in particular to a remote control liquid crystal display performance testing device and testing method. Background Technology

[0002] LCD screens are a crucial display component commonly used in air conditioner remote controls, with high demand and demanding performance requirements. The quality of the incoming LCD material affects production costs and, consequently, the quality of the air conditioner product. During remote control assembly, the LCD screen needs to be fixed to the PCB circuit board using screws. Before fixing, the LCD screen must be tested to ensure it displays correctly. If it passes the test, it is then fixed with screws; otherwise, it needs to be returned to the factory for repair. Since the LCD screen and PCB circuit board are not yet fixed during testing, external force needs to be applied to the LCD screen to ensure contact between the LCD screen and the PCB circuit board, thus enabling normal display function.

[0003] Currently, common methods for testing the LCD display function of remote controls involve manually applying force to the clamp or using the force generated by the attraction between magnets to press the LCD screen. Since the magnetic attraction is a fixed value and decreases over time, it has the drawbacks of fixed pressure and inability to adjust upwards or downwards. Changing the applied force by replacing / adding magnets is not quick enough. Relying on manual force application requires the operator to hold the remote control with one hand and apply external force with the other, which makes it impossible to effectively control the amount of external force applied to the remote control housing. Applying too much force can damage the remote control, while applying too little force can cause the LCD screen to fail to make effective contact with the PCB circuit board, seriously affecting the testing efficiency. Summary of the Invention

[0004] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide a remote control LCD display performance testing device. Under the action of the operating handle, the second platform can smoothly and bufferably apply force to the remote control, avoiding rigid collision between the second platform and the remote control, which could cause damage to the remote control. By applying force to the remote control through the operating handle, the magnitude of the applied force can be adjusted independently according to the model of the remote control, making it more versatile.

[0005] A remote control LCD display performance testing device, comprising: The first platform is provided with a placement position for a remote control; the remote control includes an unsecured LCD screen and a PCB circuit board. A second platform parallel to the first platform includes a pressure plate corresponding to the press position of the remote control in the placement position, and a first spring is provided between the second platform and the first platform; The operating handle is used to move the second platform toward the first platform, so that the LCD screen in the remote control comes into contact with the PCB circuit board.

[0006] In a preferred embodiment of the present invention, the placement position is a placement groove for placing a remote control, and the second platform is provided with a positioning groove adapted to the end of the operating handle.

[0007] To ensure the remote control does not shift during the downward pressure process, this application includes a placement groove in the first platform that matches the bottom of the remote control. The depth of the groove is less than the height of the remote control, ensuring the top casing of the remote control is exposed for pressure from the second platform. To ensure a secure connection between the second platform and the operating handle, this application includes a positioning groove in the second platform that matches the operating handle. The nesting of the positioning groove and the bottom end of the operating handle ensures a unique connection position. The interference fit between the positioning groove and the bottom end of the operating handle ensures synchronous lifting and lowering. After the test is complete, lifting the operating handle causes the second platform to reset synchronously, facilitating the movement of the remote control in and out.

[0008] In a preferred embodiment of the present invention, a base is further included, and a second spring is provided between the first platform and the base. Under the elastic force of the second spring and the pressure of the second platform, the second platform can be raised and lowered relative to the base.

[0009] This application incorporates a second spring between the base and the first platform. When the operating handle pushes the second platform down, the top of the first platform cushions contact with the second platform via the first spring, while the bottom of the first platform is also cushioned by the second spring. This provides cushioning at both the top and bottom of the remote control located within the first platform. When the operating handle applies force, it acts on the top of the remote control within the first platform via the second platform and the first spring, overcoming the elasticity of the second spring, and acting on the remote control housing, thus connecting the LCD screen and the PCB circuit board. By simultaneously cushioning the top and bottom of the first platform, this application ensures that the top and bottom of the remote control receive cushioned contact, preventing damage from rigid contact.

[0010] In a preferred embodiment of the present invention, a first guide post is provided on the base, and a first spring and a guide sleeve are nested sequentially from bottom to top on the outer side of the first guide post. The guide sleeve is fixedly connected to the side of the second platform; the two ends of the first spring abut against the guide sleeve and the first platform, respectively.

[0011] In this application, the bottom of the first guide post is fixed in the base, and the guide sleeve in the first guide post is fixed together with the second platform, and the two move up and down synchronously. The two ends of the first spring act on the bottom of the guide sleeve and the top of the first platform, respectively. When the operating handle drives the second platform to descend, the guide sleeve compresses the first spring. Since the upper part of the remote control is exposed outside the placement groove, when the height of the compressed first spring is less than or equal to the height of the remote control exposed outside the placement groove, the second platform can apply downward pressure to the remote control housing. Through the setting of the first spring and the guide sleeve, it can be ensured that the second platform can act on the remote control housing, while ensuring that the force of the second platform acting on the remote control is a buffered contact, avoiding rigid contact with the remote control.

[0012] In a preferred embodiment of the present invention, a second guide post is provided on the base, the second guide post penetrates the first platform and is slidably connected to the first platform; the second spring is nested on the outside of the second guide post, and the two ends of the second spring abut against the base and the first platform respectively.

[0013] The first platform of this application has a through hole, through which a second guide post passes. The through hole and the second guide post are clearance-fitted to ensure that the first platform can slide relative to the second guide post. The inner diameter of the through hole is smaller than the outer diameter of the second spring. When the second spring is nested outside the second guide post, it ensures that the second spring only abuts against the bottom of the through hole and will not enter the through hole. The second spring in this application provides cushioning at the bottom of the first platform. When the operating handle moves the second platform into the remote control of the first platform, in addition to the cushioned contact between the second and first platforms, the bottom of the first platform will also slowly move downward, achieving simultaneous cushioning of the bottom and top of the first platform, further preventing the remote control from being rigidly contacted.

[0014] In a preferred embodiment of the present invention, a guide post is provided on the base, and a second spring, a second connecting member, a first spring, and a first connecting member are slidably arranged sequentially from bottom to top on the outer side of the guide post. The first connecting member is fixedly connected to the side of the first platform, and the second connecting member is fixedly connected to the side of the second platform. The two ends of the first spring abut against the second connecting member and the first connecting member, respectively, and the two ends of the second spring abut against the base and the second connecting member, respectively.

[0015] This application can also combine the first guide post and the second guide post into a single guide post. At the same time, the first connector and the first platform are fixed together to maintain synchronous lifting and lowering, and the second connector and the second platform are fixed together to maintain synchronous lifting and lowering. In this way, the bottom of the first platform is buffered by the first spring and the base, and the top of the first platform is buffered by the second spring and the second platform. When the operating handle moves the second platform to act on the remote control of the first platform, in addition to the buffered contact between the second platform and the first platform, the bottom of the first platform will also slowly move down, achieving simultaneous buffering of the bottom and top of the first platform, further preventing the remote control from being rigidly contacted.

[0016] In a preferred embodiment of the present invention, the system further includes a base, on which a support plate is disposed, the support plate being perpendicular to the base; the operating handle includes a fixed end and a pressing end, the fixed end being located on the side of the second platform away from the first platform; the fixed end is C-shaped and fixed in the support plate, and the line connecting the two sides of the C-shaped opening in the fixed end is perpendicular to the plane where the first platform is located; the pressing end passes through both sides of the C-shaped opening and is fixedly connected to the second platform.

[0017] This application features a fixed end with a C-shaped opening, fixing the bottom outer side of the C-shaped opening to a support plate. A downward pressure end is located at the opening of the C-shaped opening, with the two ends of the opening arranged vertically. The downward pressure end passes through both the upper and lower openings of the C-shaped opening, extending to a position where it abuts against the second platform. This application secures the downward pressure end using the fixed end of the C-shaped opening and limits its movement through the two opening positions, ensuring that the downward pressure end can always move vertically, thus ensuring that the downward pressure force acts vertically on the second platform.

[0018] In a preferred embodiment of the present invention, the pressing end includes a handle, a hinged section, and a pressing sleeve, wherein the handle is a bent structure; a limiting ring is provided at the opening of the fixed end near the second platform, and the pressing sleeve passes through the limiting ring; the top of the pressing sleeve is hinged to the first end of the hinged section, the second end of the hinged section is hinged to the corner of the handle, the first end of the handle provides a handhold position, and the second end of the handle is hinged to the opening of the fixed end away from the second platform.

[0019] A limiting ring is provided at the bottom of the C-shaped opening at the fixed end of this application. The axis of the limiting ring extends vertically, and the inner diameter of the limiting ring is slightly larger than the inner diameter of the pressing sleeve, allowing the pressing sleeve to pass through the limiting ring. The function of the limiting ring is to ensure that the lifting direction of the pressing sleeve is the same as the axis direction of the limiting ring, both being vertical. The handle with the bent structure can be, for example, an L-shaped structure. When the operator holds the handle in the handheld position and presses it down, the corner of the handle moves down, causing the hinge section and the pressing sleeve to move down, thereby pressing down the second platform; when the operator holds the handle in the handheld position and raises it, the corner of the handle moves up, causing the hinge section and the pressing sleeve to move up, thereby resetting the second platform.

[0020] In a preferred embodiment of the present invention, a screw is provided on the inner side of the pressing sleeve near the second platform. The screw is threadedly connected to the pressing sleeve. Under the pressing action of the handle, the screw is used to abut against the second platform.

[0021] In this application, the effective length of the pressure sleeve is equal to the sum of the height of the pressure sleeve and the height of the screw exposed on the outside of the pressure sleeve. Simultaneously, the screw can be screwed in and out of the pressure sleeve via a thread. When the screw is screwed into the pressure sleeve, the length of the screw exposed on the outside of the pressure sleeve is relatively low, meaning the effective length of the pressure sleeve is small; when the screw is screwed out of the pressure sleeve, the length of the screw exposed on the outside of the pressure sleeve is relatively high, meaning the effective length of the pressure sleeve is large. This application allows the screw height to be set according to the thickness of the remote control. When the remote control is thicker, the height of the screw exposed on the outside of the pressure sleeve is adjusted to be smaller; when the remote control is thinner, the height of the screw exposed on the outside of the pressure sleeve is adjusted to be larger, ensuring that the pressure force of the handle is not significantly different, thus adapting to different sizes and models of remote controls.

[0022] The second objective of this application is to provide a method for testing the performance of a remote control's liquid crystal display, implemented based on the remote control liquid crystal display performance testing device described above, including: Place the remote control in the designated spot on the first platform; The operating handle drives the second platform to press down on the remote control, causing the LCD screen in the remote control to come into contact with the PCB circuit board.

[0023] Observe whether the LCD screen in the remote control can display normally.

[0024] The beneficial effects of this invention are as follows: This invention provides a remote control LCD display performance testing device, comprising a first platform, a second platform, and an operating handle that are parallel to each other. The first platform has a placement position for placing the remote control. The remote control includes an unsecured LCD screen and a PCB circuit board. The second platform is parallel to the first platform and includes a pressure plate corresponding to the pressing position of the remote control in the placement position. A first spring is provided between the second platform and the first platform. The operating handle is used to move the second platform toward the first platform, so that the LCD screen in the remote control abuts and connects with the PCB circuit board. This application places the remote control in the placement position, and the operating handle drives the second platform to press down on the remote control in the first platform. Because the first spring is provided between the first and second platforms, the second platform can smoothly and bufferably apply force to the remote control under the action of the operating handle, avoiding rigid collisions between the second platform and the remote control, thus preventing damage to the remote control. The force applied to the remote control by the operating handle can be adjusted according to the model of the remote control, making it more versatile. Furthermore, the operator only needs to control the operating handle, eliminating the need for hand-holding or securing the remote control, making the testing process more convenient and efficient.

[0025] This application also provides a method for testing the performance of a remote control's LCD display, comprising: placing the remote control in the placement position of a first platform; using an operating handle to drive the second platform to press down on the remote control; causing the LCD screen in the remote control to contact and connect with the PCB circuit board; and observing whether the LCD screen in the remote control can display normally. Because a first spring is provided between the first and second platforms, under the action of the operating handle, the second platform can smoothly and bufferingly apply force to the remote control, avoiding rigid collisions between the second platform and the remote control, thus preventing damage to the remote control; by applying force to the remote control through the operating handle, the magnitude of the applied force can be adjusted independently according to the remote control model, making it more versatile; and the operator only needs to control the operating handle, without needing to hold the remote control tightly, making the testing process more convenient and efficient.

Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0029] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0030] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Example 1 This application provides a remote control LCD display performance testing device, comprising: The first platform 11 is provided with a placement position for a remote control; the remote control includes an unsecured LCD screen and a PCB circuit board. A second platform 12 parallel to the first platform 11 includes a pressure plate corresponding to the press position of the remote control in the placement position, and a first spring 15 is provided between the second platform 12 and the first platform 11. The operating handle is used to move the second platform 12 toward the first platform 11, so that the LCD screen in the remote control comes into contact with the PCB circuit board.

[0032] In this application, the operating handle can be fixed together with the second platform 12 to ensure that the operating handle and the second platform 12 are raised and lowered synchronously. After the test is completed, simply raise the operating handle to reset the second platform 12 and the operating handle, which facilitates the movement of the remote control in and out.

[0033] In this application, the remote control refers to a remote control in the assembly process before the fastening screws are installed. The fastening screws are used to secure the LCD screen and the PCB circuit board, ensuring effective electrical conductivity between them. Before tightening, it is necessary to test whether the LCD screen can display normally. Normal display here means that, with electrical conductivity with the PCB circuit board, the logo characters can be clearly displayed on the LCD screen. Since the LCD screen is not yet fixed to the PCB circuit board at this stage, external force is needed to press them together. After pressing, if the LCD screen can display the logo characters, it indicates that the LCD screen's display function is normal. If the LCD screen cannot display normally or the displayed logo characters are incomplete, it indicates that the LCD screen's display function is defective and requires repair.

[0034] In this application, the pressable position of the remote control in the placement position refers to the housing of the LCD screen accessory in the remote control. By pressing the housing, the LCD screen is moved down to the position where it contacts the PCB circuit board, thus realizing the connection between the two.

[0035] In this application, the remote control is placed in the placement position, and the second platform 12 is pressed down towards the remote control in the first platform 11 by the operation handle. Since the first platform 11 and the second platform 12 are provided with a first spring 15, the second platform 12 can smoothly and buffer the force applied to the remote control under the action of the operation handle, so as to avoid the second platform 12 and the remote control from rigidly colliding and causing damage to the remote control.

[0036] This application applies force to the remote control by operating the handle, and the magnitude of the applied force can be adjusted independently according to the model of the remote control, making it more versatile.

[0037] During the testing process, the remote control is fixed in the placement position of the test device of this application. Under the action of external force, the operating handle can drive the second platform 12 to press down on the remote control in the first platform 11. That is, the operator only needs to control the operating handle and does not need to perform operations such as holding the remote control tightly, making the testing process more convenient and efficient.

[0038] This application also provides a method for testing the performance of a remote control's LCD display, including: Place the remote control in the placement position of the first platform 11; The operating handle drives the second platform 12 to press down the remote control, causing the LCD screen in the remote control to come into contact with the PCB circuit board. Observe whether the LCD screen in the remote control can display normally.

[0039] Because a first spring 15 is provided between the first platform 11 and the second platform 12, the second platform 12 can smoothly and bufferably apply force to the remote control under the action of the operating handle, avoiding rigid collision between the second platform 12 and the remote control, which could cause damage to the remote control. By applying force to the remote control through the operating handle, the magnitude of the applied force can be adjusted according to the model of the remote control, making it more versatile. Moreover, the operator only needs to control the operating handle and does not need to perform operations such as holding the remote control tightly, making the testing process more convenient and efficient.

[0040] Example 2 This application provides a remote control LCD display performance testing device, comprising: The first platform 11 is provided with a placement position for a remote control; the remote control includes an unsecured LCD screen and a PCB circuit board. A second platform 12 parallel to the first platform 11 includes a pressure plate corresponding to the press position of the remote control in the placement position, and a first spring 15 is provided between the second platform 12 and the first platform 11. The operating handle is used to move the second platform 12 toward the first platform 11, so that the LCD screen in the remote control comes into contact with the PCB circuit board.

[0041] Furthermore, the placement position is a placement groove for placing the remote control, and the second platform 12 is provided with a positioning groove that is adapted to the end of the operating handle.

[0042] To ensure the remote control does not shift during the downward pressure process, this application provides a placement groove in the placement position of the first platform 11 that matches the bottom of the remote control. The depth of the placement groove is less than the height of the remote control, ensuring that the top shell of the remote control is exposed, facilitating the pressure of the second platform 12. To ensure a stable connection between the second platform 12 and the operating handle, this application provides a positioning groove in the second platform 12 that matches the operating handle. The nesting of the positioning groove and the bottom end of the operating handle ensures a unique connection position. The interference fit between the positioning groove and the bottom end of the operating handle ensures that they move up and down synchronously. After the test is completed, lifting the operating handle will synchronously reset the second platform 12, facilitating the movement of the remote control in and out.

[0043] Furthermore, it also includes a base 13, and a second spring 16 is provided between the first platform 11 and the base 13. Under the elastic force of the second spring 16 and the pressure of the second platform 12, the second platform 12 can be raised and lowered relative to the base 13.

[0044] This application incorporates a second spring 16 between the base 13 and the first platform 11. When the operating handle pushes the second platform 12 down, the top of the first platform 11 is cushioned against the second platform 12 by the first spring 15. Simultaneously, the bottom of the first platform 11 is cushioned by the second spring 16. Thus, both the top and bottom of the remote control located on the first platform 11 are cushioned. When the force applied by the operating handle acts on the top of the remote control on the first platform 11 through the second platform 12 and the first spring 15, this force must overcome the elasticity of the second spring 16 and act on the remote control housing, connecting the LCD screen and the PCB circuit board. By simultaneously cushioning the top and bottom of the first platform 11, this application ensures that both the top and bottom of the remote control can be cushioned, preventing damage to the remote control from rigid contact.

[0045] Furthermore, a first guide post 17 is provided on the base 13, and a first spring 15 and a guide sleeve 18 are nested on the outer side of the first guide post 17 from bottom to top. The guide sleeve 18 is fixedly connected to the side of the second platform 12, and the two ends of the first spring 15 abut against the guide sleeve 18 and the first platform 11 respectively.

[0046] In this application, the bottom of the first guide post 17 is fixed in the base 13. The guide sleeve 18 in the first guide post 17 is fixed together with the second platform 12, and the two move up and down synchronously. The two ends of the first spring 15 act on the bottom of the guide sleeve 18 and the top of the first platform 11, respectively. When the operating handle drives the second platform 12 to descend, the guide sleeve 18 compresses the first spring 15. Since the upper part of the remote control is exposed outside the placement groove, when the height of the compressed first spring 15 is less than or equal to the height of the remote control exposed outside the placement groove, the second platform 12 can apply downward pressure to the remote control housing. Through the arrangement of the first spring 15 and the guide sleeve 18, it can be ensured that the second platform 12 can act on the remote control housing, while ensuring that the force of the second platform 12 acting on the remote control is a buffered contact, avoiding rigid contact with the remote control.

[0047] Furthermore, a second guide post is provided on the base 13, the second guide post passes through the first platform 11 and is slidably connected to the first platform 11; the second spring 16 is nested on the outside of the second guide post, and the two ends of the second spring 16 abut against the base 13 and the first platform 11 respectively.

[0048] The first platform 11 of this application has a through hole, and a second guide post passes through the through hole in the first platform 11. The through hole and the second guide post are in clearance fit to ensure that the first platform 11 can slide relative to the second guide post. The inner diameter of the through hole is smaller than the outer diameter of the second spring 16. When the second spring 16 is nested outside the second guide post, it ensures that the second spring 16 only abuts against the bottom of the through hole and will not enter the through hole. The second spring 16 in this application can achieve buffering at the bottom of the first platform 11. When the operating handle drives the second platform 12 to act on the remote control of the first platform 11, in addition to the buffered contact between the second platform 12 and the first platform 11, the bottom of the first platform 11 will also slowly move down, achieving simultaneous buffering of the bottom and top of the first platform 11, further preventing the remote control from being rigidly contacted.

[0049] Furthermore, a guide post 32 is provided on the base 13. A second spring 16, a second connector, a first spring 15, and a first connector 31 are slidably arranged on the outer side of the guide post 32 from bottom to top. The first connector 31 is fixedly connected to the side of the first platform 11, and the second connector is fixedly connected to the side of the second platform 12. The two ends of the first spring 15 abut against the second connector and the first connector 31, respectively, and the two ends of the second spring 16 abut against the base 13 and the second connector, respectively.

[0050] In another embodiment, the first guide post 17 and the second guide post can be combined into a guide post 32. At the same time, the first connector 31 and the first platform 11 are fixed together to maintain synchronous lifting and lowering, and the second connector and the second platform 12 are fixed together to maintain synchronous lifting and lowering. In this way, the bottom of the first platform 11 is buffered between the first spring 15 and the base 13, and the top of the first platform 11 is buffered between the second spring 16 and the second platform 12. When the operating handle drives the second platform 12 to act on the remote control of the first platform 11, in addition to the buffered contact between the second platform 12 and the first platform 11, the bottom of the first platform 11 will also slowly move down, realizing simultaneous buffering of the bottom and top of the first platform 11, further preventing the remote control from being rigidly contacted.

[0051] Furthermore, it also includes a base 13, on which a support plate 14 is provided, the support plate 14 being perpendicular to the base 13; the operating handle includes a fixed end 20 and a pressing end, the fixed end 20 being located on the side of the second platform 12 away from the first platform 11; the fixed end 20 is C-shaped and fixed in the support plate 14, and the line connecting the two sides of the C-shaped opening in the fixed end 20 is perpendicular to the plane where the first platform 11 is located; the pressing end passes through both sides of the C-shaped opening and is fixedly connected to the second platform 12.

[0052] This application provides a fixed end 20 for the C-shaped opening, so that the bottom outer side of the C-shaped opening is fixed in the support plate 14. A pressing end is provided at the opening of the C-shaped opening, and the two ends of the opening of the C-shaped opening are distributed vertically. The pressing end passes through the upper opening and the lower opening of the C-shaped opening in sequence, extending to the position where it abuts against the second platform 12. This application fixes the pressing end by the fixed end 20 of the C-shaped opening and limits the pressing end by the two opening positions of the C-shaped opening, ensuring that the pressing end can always move up and down in the vertical direction, and ensuring that the pressing force acts vertically on the second platform 12.

[0053] Further, the pressing end includes a handle 24, a hinge section 21, and a pressing sleeve 22. The handle 24 has a bent structure. A limiting ring 23 is provided at the opening of the fixed end 20 near the second platform 12, and the pressing sleeve 22 passes through the limiting ring 23. The top of the pressing sleeve 22 is hinged to the first end of the hinge section 21, and the second end of the hinge section 21 is hinged to the corner of the handle 24. The first end of the handle 24 provides a handhold position, and the second end of the handle 24 is hinged to the opening of the fixed end 20 away from the second platform 12.

[0054] A limiting ring 23 is provided at the bottom of the C-shaped opening of the fixed end 20 of this application. The axis of the limiting ring 23 extends vertically, and the inner diameter of the limiting ring 23 is slightly larger than the inner diameter of the pressing sleeve 22, so that the pressing sleeve 22 can pass through the limiting ring 23. The function of the limiting ring 23 is to ensure that the lifting direction of the pressing sleeve 22 is the same as the axis direction of the limiting ring 23, both being vertical. The bent handle 24 can be, for example, an L-shaped structure. When the operator holds the handle in the hand position and presses it down, the corner of the handle 24 moves down, causing the hinge section 21 and the pressing sleeve 22 to move down, thereby pressing down the second platform 12; when the operator holds the handle in the hand position and raises the handle 24, the corner of the handle 24 moves up, causing the hinge section 21 and the pressing sleeve 22 to move up, thereby resetting the second platform 12.

[0055] Furthermore, a screw 19 is provided on the inner side of the pressing sleeve 22 near the second platform 12. The screw 19 is threadedly connected to the pressing sleeve 22. Under the pressing action of the handle 24, the screw 19 is used to abut against the second platform 12.

[0056] In this application, the effective length of the pressing sleeve 22 is equal to the sum of the height of the pressing sleeve 22 and the height of the screw 19 exposed on the outside of the pressing sleeve 22. Simultaneously, the screw 19 can be screwed in and out of the pressing sleeve 22 via a thread. When the screw 19 is screwed into the pressing sleeve 22, the length of the screw 19 exposed on the outside of the pressing sleeve 22 is relatively low, meaning the effective length of the pressing sleeve 22 is small. When the screw 19 is screwed out of the pressing sleeve 22, the length of the screw 19 exposed on the outside of the pressing sleeve 22 is relatively high, meaning the effective length of the pressing sleeve 22 is large. This application allows the height of the screw 19 to be set according to the thickness of the remote control. When the remote control is thick, the height of the screw 19 exposed on the outside of the pressing sleeve 22 is adjusted to be smaller; when the remote control is thin, the height of the screw 19 exposed on the outside of the pressing sleeve 22 is adjusted to be larger, ensuring that the pressing force of the handle 24 is not significantly different, thus adapting to different sizes and models of remote controls.

[0057] Example 3 like Figures 1-3 As shown, this application provides a remote control LCD display performance testing device, wherein the remote control includes an unsecured LCD display and a PCB circuit board; the testing device includes a base 13, a first platform 11, a second platform 12, and an operating handle disposed on the top of the second platform 12, which are parallel to each other from bottom to top.

[0058] The first platform 11 is provided with a placement position for placing the remote control; the placement position is a placement groove for placing the remote control, and the depth of the placement groove is less than the height of the remote control, so as to ensure that the top shell of the remote control is exposed, making it easy for the second platform 12 to press it down.

[0059] The second platform 12 includes a pressure plate corresponding to the pressable position of the remote control in the placement position, which refers to the remote control housing around the LCD screen. The second platform 12 has a positioning groove that matches the bottom of the screw 19 in the operating handle. The nesting of the positioning groove and the bottom of the screw 19 ensures a unique connection position, and the interference fit between the positioning groove and the bottom of the screw 19 ensures synchronous lifting and lowering.

[0060] The base 13 is provided with a first guide post 17 and a second guide post, which are staggered. There are two first guide posts 17 and two second guide posts. A first spring 15 and a guide sleeve 18 are nested sequentially from bottom to top on the outer side of the first guide post 17. The guide sleeve 18 is fixedly connected to the side of the second platform 12. The two ends of the first spring 15 abut against the guide sleeve 18 and the first platform 11, respectively. When the operating handle lowers the second platform 12, the guide sleeve 18 compresses the first spring 15. Since the upper part of the remote control is exposed outside the placement groove, when the height of the compressed first spring 15 is less than or equal to the height of the remote control exposed outside the placement groove, the second platform 12 can apply downward pressure to the remote control housing.

[0061] The first platform 11 has a through hole, through which a second guide post passes. The through hole and the second guide post are clearance-fitted to ensure that the first platform 11 can slide relative to the second guide post. The inner diameter of the through hole is smaller than the outer diameter of the second spring 16. When the second spring 16 is nested outside the second guide post, it ensures that the second spring 16 only abuts against the bottom of the through hole and does not enter the through hole. The two ends of the second spring 16 abut against the base 13 and the first platform 11, respectively. The bottom of the first platform 11 is buffered between the first spring 15 and the base 13, and the top of the first platform 11 is buffered between the second spring 16 and the second platform 12. When the operating handle moves the second platform 12 into the remote control of the first platform 11, in addition to the buffered contact between the second platform 12 and the first platform 11, the bottom of the first platform 11 also slowly moves down, achieving simultaneous buffering of the bottom and top of the first platform 11, further preventing the remote control from being rigidly contacted.

[0062] A support plate 14 is provided on the base 13, and the support plate 14 is set perpendicular to the base 13; the operating handle includes a fixed end 20 and a pressing end, the fixed end 20 is located above the second platform 12; the fixed end 20 is fixed in the support plate 14 in a C shape, and the two sides of the C-shaped opening in the fixed end 20 extend in the vertical direction; the pressing end passes through the two sides of the C-shaped opening and is fixedly connected to the second platform 12. Specifically, the pressing end includes a handle 24, a hinge section 21, and a pressing sleeve 22. The handle 24 has a bent structure. A limit ring 23 is provided at the lower end of the opening in the fixed end 20. The pressing sleeve 22 passes through the limit ring 23, and the axis of the limit ring 23 extends vertically. The inner diameter of the limit ring 23 is slightly larger than the inner diameter of the pressing sleeve 22, allowing the pressing sleeve 22 to pass through the limit ring 23. The function of the limit ring 23 is to ensure that the lifting direction of the pressing sleeve 22 is the same as the axial direction of the limit ring 23, both being vertical. The top of the pressing sleeve 22 is hinged to the first end of the hinge section 21, and the second end of the hinge section 21 is hinged to the corner of the handle 24. The first end of the handle 24 provides a handhold, and the second end of the handle 24 is hinged to the opening in the fixed end 20 away from the second platform 12. A screw 19 is provided on the inner side of the pressing sleeve 22 near the second platform 12. The screw 19 is threadedly connected to the pressing sleeve 22. Under the pressing action of the handle 24, the screw 19 is used to abut against the second platform 12. When the screw 19 is screwed into the pressing sleeve 22, the length of the screw 19 exposed on the outside of the pressing sleeve 22 is relatively low, that is, the effective length of the pressing sleeve 22 is small. When the screw 19 is screwed out of the pressing sleeve 22, the length of the screw 19 exposed on the outside of the pressing sleeve 22 is relatively high, that is, the effective length of the pressing sleeve 22 is large.

[0063] This application also provides a method for testing the performance of a remote control's LCD display, including: Place the remote control in the placement position of the first platform 11; the handle 24 drives the second platform 12 to press down the remote control; so that the LCD screen in the remote control abuts and connects with the PCB circuit board; observe whether the LCD screen in the remote control can display normally.

[0064] Specifically, when the operator holds the handle and presses it down, the corner of the handle 24 moves downward, causing the hinge section 21 and the pressing sleeve 22 to move downward, thus pressing down on the second platform 12. The downward movement of the second platform 12 compresses the first spring 15 until the first spring 15 is compressed to a thickness less than that of the remote control exposed outside the placement groove. At this time, the pressure of the second platform 12 on the first platform 11 is transmitted to the second spring 16, which is compressed, providing double-sided cushioning for the top and bottom of the first platform 11. The second platform 12 continues to press down, overcoming the elastic force of the first spring 15 and the second spring 16, and pressing down on the remote control housing, so that the LCD screen in the remote control abuts and connects with the PCB circuit board. After the two abut, if the LCD screen can display the logo characters, it means that the display function of the LCD screen is normal. If the LCD screen cannot display normally or the displayed logo characters are incomplete, it means that the display function of the LCD screen is defective and needs to be repaired. After the test is completed, when the operator holds the handle 24 in the hand position and lifts it, the corner of the handle 24 moves upward, which drives the hinge section 21 and the pressure sleeve 22 to move upward, thereby resetting the second platform 12.

[0065] This application allows setting the corresponding screw 19 height and handle 24 lower limit position for different models of remote controls. During the testing process, the LCD screen is constantly monitored to see if it displays normally. If it displays normally, the pressure on handle 24 is stopped. If it still cannot display normally when pressed down to the lower limit position, the LCD screen of the remote control is determined to have a display fault, thus avoiding excessive pressure that could damage the remote control.

[0066] Example 4 like Figure 4 As shown, this application provides a remote control LCD display performance testing device, wherein the remote control includes an unsecured LCD display and a PCB circuit board; the testing device includes a base 13, a first platform 11, a second platform 12, and an operating handle disposed on the top of the second platform 12, which are parallel to each other from bottom to top.

The nesting of the positioning groove and the bottom of the screw 19 ensures a unique connection position, and the interference fit between the positioning groove and the bottom of the screw 19 ensures synchronous lifting and lowering.

[0069] A guide post 32 is provided on the base 13. A second spring 16, a second connector, a first spring 15, and a first connector 31 are slidably arranged sequentially from bottom to top on the outer side of the guide post 32.

The two ends of the first spring 15 abut against the second connector and the first connector 31, respectively. The two ends of the second spring 16 abut against the base 13 and the second connector, respectively. The bottom of the first platform 11 is buffered between the first spring 15 and the base 13, and the top of the first platform 11 is buffered between the second spring 16 and the second platform 12. When the operating handle moves the second platform 12 into the remote control of the first platform 11, in addition to the buffered contact between the second platform 12 and the first platform 11, the bottom of the first platform 11 also slowly moves downwards, achieving simultaneous buffering of the bottom and top of the first platform 11, further preventing the remote control from being rigidly contacted.

[0070] A support plate 14 is provided on the base 13, and the support plate 14 is set perpendicular to the base 13; the operating handle includes a fixed end 20 and a pressing end, the fixed end 20 is located above the second platform 12; the fixed end 20 is fixed in the support plate 14 in a C shape, and the two sides of the C-shaped opening in the fixed end 20 extend in the vertical direction; the pressing end passes through the two sides of the C-shaped opening and is fixedly connected to the second platform 12.

The first end of the handle 24 provides a handhold, and the second end of the handle 24 is hinged to the opening in the fixed end 20 away from the second platform 12. A screw 19 is provided on the inner side of the pressing sleeve 22 near the second platform 12. The screw 19 is threadedly connected to the pressing sleeve 22. Under the pressing action of the handle 24, the screw 19 is used to abut against the second platform 12. When the screw 19 is screwed into the pressing sleeve 22, the length of the screw 19 exposed on the outside of the pressing sleeve 22 is relatively low, that is, the effective length of the pressing sleeve 22 is small. When the screw 19 is screwed out of the pressing sleeve 22, the length of the screw 19 exposed on the outside of the pressing sleeve 22 is relatively high, that is, the effective length of the pressing sleeve 22 is large.
