Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a frame for a display device and a display device. Background Technology

[0002] Infrared touchscreens are widely used in various fields due to their strong resistance to environmental factors and high touch accuracy. For example, they are used in smart blackboards, where infrared emitting and receiving sensors form an infrared detection network on the screen surface. Any touching object can change the infrared light at the touch point, thus enabling touchscreen operation. Typically, an infrared touchscreen has a surrounding frame, which not only secures the touchscreen but also houses the infrared emitting and receiving sensors and other components.

[0003] However, when water accumulates on the touchscreen, it can seep into the bottom bezel through gaps in the frame or between the frame and the touchscreen, causing corrosion of components inside the bottom bezel and resulting in short circuits and other malfunctions. Utility Model Content

[0004] Therefore, it is necessary to provide a frame and display device to address the problem that water accumulation on infrared touch screens can easily flow into the lower bezel through the gaps in the frame or the gap between the frame and the touch screen, causing corrosion of the components inside the lower bezel.

[0005] A frame for a display device, comprising:

[0006] The frame body includes a connected side frame and a bottom frame, the side frame and the bottom frame surrounding the outer periphery of the touch panel. The bottom frame has a mounting cavity for accommodating components, the mounting cavity extending through the bottom frame along the width of the frame body to form an opening in the bottom frame; and

[0007] A waterproof component includes a connected blocking part and a flow guiding part. The blocking part is inserted into the mounting cavity to prevent water from flowing into the mounting cavity from the opening, and the flow guiding part is located outside the mounting cavity.

[0008] With the above configuration, when water accumulates in the center or edge of the touch panel of the touch screen, the water can flow to the corners of the lower frame. The blocking part can prevent water from flowing into the mounting cavity of the lower frame from the openings on the left and right sides of the lower frame. The guide part can also guide the water accumulated on the left and right sides of the lower frame, allowing the water to flow out of the frame quickly and preventing it from accumulating on the left and right sides of the lower frame. This effectively waterproofs the lower frame and prevents corrosion of components such as infrared emitting elements inside the lower frame. In addition, the waterproof component can be fixed to the lower frame by its own blocking part, without the need for additional mounting parts, which simplifies the frame structure.

[0009] In one embodiment, the lower frame has a first surface disposed on the outer periphery of the opening, and the guide portion has a second surface close to the blocking portion, the second surface abutting the first surface.

[0010] With the above settings, the guide section can block the water accumulation at the left and right ends of the lower frame once, and with the blocking section blocking the water accumulation at the left and right ends of the lower frame, the water accumulation can be blocked twice.

[0011] In one embodiment, the frame body further includes a corner connector connected to the side frame and the bottom frame, the corner connector being able to compress the guide portion so that the second surface abuts against the first surface.

[0012] With the above settings, the corner connectors can be used to compress the guide section, so that the corner connectors fit tightly against the side frame.

[0013] In one embodiment, the flow guide is provided with a process groove on the side opposite to the blocking part.

[0014] By using the above settings, the process groove can be used to prevent the guide section from shrinking during injection molding due to excessive thickness, thus avoiding deviations in the dimensions of the guide section.

[0015] In one embodiment, the flow guide portion has a first clearance groove on the side near the side frame, the first clearance groove being used to accommodate the side frame; and / or,

[0016] The blocking part has a tapering section on the side opposite to the guide part.

[0017] With the above settings, the first clearance groove can prevent the side frame from interfering with the guide section during assembly, and the tapered section can guide the insertion of the blocking section.

[0018] In one embodiment, the lower frame includes a frame body and a filter strip. The frame body has a first cavity for mounting the component and a light-transmitting opening near the touch panel and communicating with the first cavity. The filter strip covers the light-transmitting opening and cooperates with the frame body to form a second cavity. The first cavity and the second cavity constitute the mounting cavity.

[0019] The blocking portion includes a first blocking portion and a second blocking portion arranged sequentially along the height direction of the frame body. The first blocking portion is interference-fitted with the inner surface of the second cavity, and the second blocking portion abuts against at least the first inner surface of the first cavity in the height direction of the frame body. The first inner surface is close to the touch panel. The flow guide portion is connected to at least one of the first blocking portion and the second blocking portion.

[0020] With the above settings, the structure of the blocking part can be set according to the structure of the bottom frame, so that the blocking part can be effectively blocked from accumulating water and can also be fixed to the bottom frame in a simple connection method.

[0021] In one embodiment, the flow guide includes a first flow guide and a second flow guide arranged sequentially along the height direction of the frame body, wherein the first flow guide is connected to the first blocking part, and the second flow guide is connected to the second blocking part;

[0022] The second flow guide has a component mounting position on the side near the first blocking part. The component mounting position is located between the first inner surface and the second inner surface of the second cavity, and the second inner surface is opposite to the first inner surface.

[0023] With the above settings, component mounting positions are set on the second guide section. This facilitates component installation and, since the second blocking part only needs to be in contact with the first inner surface of the mounting cavity, the compatibility between the waterproof component and the lower frame can be reduced, thereby reducing the processing difficulty of the waterproof component.

[0024] In one embodiment, the dimension of the first guide portion in the thickness direction of the frame body is smaller than the dimension of the second guide portion in the thickness direction of the frame body, so that the guide portion forms a two-layer stepped structure.

[0025] The above settings facilitate the drainage of water from the left and right ends of the bottom border.

[0026] In one embodiment, a second clearance groove is provided on the side of the first blocking portion near the filter strip, the second clearance groove being used to accommodate the filter strip.

[0027] By setting it as described above, interference between the filter strip and the blocking part can be avoided during assembly.

[0028] A display device includes a touch panel, a display screen, and a frame as described in any of the preceding claims, wherein the lower border and side borders of the frame surround the outer periphery of the touch panel, and the display screen is disposed on the back side of the touch panel.

[0029] In the aforementioned display device, when water accumulates in the center or edge of the touch panel, the water can flow to the corners of the lower frame. The blocking part can prevent water from flowing from the left and right ends of the lower frame into the mounting cavity of the lower frame through the opening in the lower frame. The guide part can also guide the water accumulated at the left and right ends of the lower frame, allowing the water at the left and right ends of the frame to flow out of the frame quickly, avoiding accumulation at the left and right ends of the lower frame. This effectively waterproofs the lower frame and prevents corrosion of components such as infrared emitting elements inside the lower frame. In addition, the waterproof component can be fixed to the lower frame by its own blocking part, without the need for additional mounting parts, which simplifies the frame structure.

Detailed Implementation

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] Infrared touchscreens utilize infrared emitting and receiving sensing elements to form an infrared detection network on the screen surface. Any touching object can alter the infrared light emitted at the touch point, thus enabling touchscreen operation. An infrared touchscreen comprises a stacked display screen and a touch panel. The touch panel has a surrounding bezel, which not only secures the infrared touchscreen but also houses the infrared emitting and receiving sensing elements and other components.

[0049] The frame consists of a top frame, a left frame, a bottom frame, and a right frame that are joined together in sequence. Depending on the specific application of the touch screen, infrared emitting and receiving sensing elements and other components can be installed in the corresponding frame. For example, in the field of smart blackboards, in order to facilitate the connection between the main screen of the smart blackboard (the "infrared touch screen" mentioned above) and the secondary screen (a blackboard that can be written on with chalk), the left and right frames of the infrared touch screen are generally made very thin, serving only to fix the touch screen. One of the top and bottom frames is used to install infrared emitting elements and other components, while the other is used to install infrared receiving sensing elements and other components.

[0050] To facilitate the installation of infrared emitting and receiving sensors and other components, the top and bottom bezels are typically hollow structures with openings at the left and right ends. These components can be installed within the top and bottom bezels through these openings. However, when water accumulates on the touch panel due to cleaning or other reasons, water from the edges first seeps into the gaps between the touch panel and the left and right bezels. Then, it enters the bottom bezel through the openings at the left and right ends. Water in the center of the touch panel first seeps into the gap between the touch panel and the bottom bezel, then flows through the gaps between the left and right bezels and the bottom bezel to the left and right ends of the bottom bezel, finally entering the bottom bezel through the openings at the left and right ends. Once water seeps into the bottom bezel, it can corrode the components inside, causing short circuits and other malfunctions.

[0051] This application provides a waterproof component at the end opening of the lower frame. This waterproof component can prevent water from accumulating at the left and right ends of the lower frame from flowing into the mounting cavity of the lower frame. It can also guide the water accumulated at the left and right ends of the lower frame, allowing the water to flow out of the frame. This prevents long-term water accumulation at the left and right ends of the lower frame, effectively waterproofing the lower frame and preventing corrosion of components such as infrared emitting elements inside the lower frame.

[0052] like Figure 1 As shown, one embodiment of this application provides a frame 10, which can serve as the frame 10 of a display device and can be arranged around the touch panel 20 of the display device. The display device can be the main screen of a smart blackboard, or it can be a smart interactive flat panel whose lower frame requires the installation of infrared transmitting and receiving sensing elements and other components.

[0053] Furthermore, such as Figure 2 and Figure 3 As shown, the frame 10 includes a frame body 100 and a waterproof component 200. Wherein, as... Figure 2 and Figure 4As shown, the frame body 100 includes side frames (i.e., left frame 110 and right frame 120), top frame 140 and bottom frame 130. The side frames are connected to the top and bottom frames and surround the outer periphery of the touch panel 20.

[0054] The side frame mainly serves to fix the touch panel 20, such as Figure 2 As shown, it may include a left border 110 and a right border 120, which are positioned at both ends of the bottom border 130 along the width direction of the frame body 100. It should be noted that the terms "up," "down," "left," "right," "front," and "back" throughout the text are all relative to the left and right borders. Figure 2 The one shown is the standard, among which, Figure 2 The left and right directions shown can be the width direction of the main frame 100. Figure 2 The vertical direction shown can be the height direction of the main frame body 100. Figure 2 The front-back direction shown can be the thickness direction of the frame body 100.

[0055] The top and bottom bezels are mainly used to mount infrared emitting and receiving sensing elements and other components. For example, infrared emitting sensing elements and other components are mounted in the bottom bezel 130, and infrared receiving sensing elements and other components are mounted in the top bezel 140. The structures of the top bezel 140 and the bottom bezel 130 can be the same. The following description uses the bottom bezel 130 as an example to illustrate the structure of the top and bottom bezels. Figure 5 As shown, the lower frame 130 has a mounting cavity 130a for accommodating components. The mounting cavity 130a extends through the lower frame 130 along the width direction of the frame body 100 to form an opening in the frame body 100. Components can be mounted into the mounting cavity 130a of the lower frame 130 through the opening in the frame body 100, facilitating component mounting.

[0056] like Figure 5 and Figure 6 As shown, the lower frame 130 includes a frame body 131 and a light filter strip 132. The frame body 131 has a first cavity 131a and a light-transmitting opening 131b. The first cavity 131a is used for mounting components, and the light-transmitting opening 131b is close to the touch panel 20 and communicates with the first cavity 131a. The light filter strip 132 covers the light-transmitting opening 131b and cooperates with the frame body 131 to form a second cavity 132a. The first cavity 131a and the second cavity 132a constitute the mounting cavity 130a. It can be understood that the first cavity 131a, the second cavity 132a, and the light-transmitting opening 131b all penetrate the lower frame 130 along the width direction of the frame body 100. When the lower frame 130 is installed below the touch panel 20, the light filter strip 132 is held between the lower frame 130 and the touch panel 20. Typically, the top of the lower frame 130 presses the light filter strip 132 onto the touch panel 20.

[0057] like Figure 3 As shown, the frame body 100 also includes corner connectors 150, which are connected to the side frame and the bottom frame 130. As an example, the lower end of the left side frame 110 is connected to the left end of the bottom frame 130 via the corner connector 150, and the lower end of the right side frame 120 is also connected to the right end of the bottom frame 130 via the corner connector 150.

[0058] Optionally, such as Figure 5 and Figure 7 As shown, the bezel body 131 has a front panel 1311 and a back panel 1312 arranged sequentially along the thickness direction of the frame body 100. The end of the front panel 1311 protrudes from the back panel 1312 along the width direction of the frame body 100. A corner connector 150 is disposed at the end of the front panel 1311 along the width direction of the frame body 100. In this way, the corner connector 150 can be hidden within the entire display device, improving the overall aesthetics of the display device. Optionally, as... Figure 3 As shown, the corner connector 150 has a first ear plate 151 on the side near the corresponding side frame and a second ear plate 152 on the side near the back plate 1312 of the frame body 131. The first ear plate 151 is screwed to the corresponding side frame, and the second ear plate 152 extends into the frame body 131 and is screwed to the back plate 1312 of the frame body 131.

[0059] Waterproof component 200 serves as the waterproof component for the entire frame 10, such as... Figures 8 to 10 As shown, it may include a blocking part 210 and a guide part 220 connected together. The blocking part 210 is inserted into the mounting cavity 130a to block water from flowing into the mounting cavity 130a from the opening, and the guide part 220 is located outside the mounting cavity 130a. When water accumulates in the middle or edge of the touch panel 20, once the water flows into the left and right ends of the lower frame 130, the blocking part 210 can prevent the water from flowing into the mounting cavity 130a of the lower frame 130 through the openings at the left and right ends of the lower frame 130. The guide part 220 can also guide the water accumulated at the left and right ends of the lower frame 130, so that the water at the left and right ends of the frame can quickly flow out of the frame 10, avoiding accumulation at the left and right ends of the lower frame 130. This can effectively waterproof the lower frame 130 and prevent corrosion of components such as infrared emitting elements inside the lower frame 130. In addition, the waterproof component 200 can be fixed to the lower frame 130 by its own blocking part 210, without the need for additional mounting parts for installation and fixation, which simplifies the structure of the frame 10.

[0060] In some embodiments of this application, such as Figure 6 and Figure 8As shown, the lower frame 130 has a first surface 130b disposed on the outer periphery of the opening, and the guide portion 220 has a second surface 220a close to the blocking portion 210, with the second surface 220a abutting against the first surface 130b. By abutting the second surface 220a of the guide portion 220 against the first surface 130b of the lower frame 130, so that there is no gap between them, water accumulation at the left and right ends of the lower frame 130 can be blocked. That is, this application uses the guide portion 220 to block water accumulation at the left and right ends of the lower frame 130 once, and uses the blocking portion 210 to block water accumulation at the left and right ends of the lower frame 130 a second time. This can effectively prevent water accumulation at the left and right ends of the lower frame 130 from flowing into the mounting cavity 130a of the lower frame 130, and can effectively protect the components in the mounting cavity 130a. In addition, when installing, once the second surface 220a of the guide portion 220 abuts against the first surface 130b of the lower frame 130, it can be determined that the waterproof component 200 is installed in place.

[0061] Optionally, the corner connector 150 can compress the guide portion 220 so that the second surface 220a abuts against the first surface 130b. When the corner connector 150 is connected to the side frame and the bottom frame 130 by means of threaded parts or the like, the corner connector 150 can compress the guide portion 220 so that the guide portion 220 fits tightly against the bottom frame 130, thus avoiding gaps between the second surface 220a of the guide portion 220 and the first surface 130b of the bottom frame 130.

[0062] Optionally, the guide portion 220 can be made of an elastic material, such as rubber. This type of material allows the guide portion 220 to be compressed under the pressure of the corner connector 150, enabling it to fit tightly against the lower frame 130. Optionally, the guide portion 220 can be injection molded integrally with the blocking portion 210 to ensure the connection strength between the two. During injection molding, the guide portion 220 may shrink due to its large thickness, affecting its dimensions and consequently the fit between the guide portion 220 and the lower frame 130. In some embodiments, such as... Figure 10 As shown, a process groove 220b can be provided on the side of the flow guide 220 opposite to the blocking part 210. The process groove 220b can prevent shrinkage of the flow guide 220 during injection molding. The process groove 220b can be formed in the thickest part of the flow guide 220. In addition, the shape and number of process grooves 220b can be set according to requirements, for example, Figure 10 As shown, an elongated oval process groove 220b is provided on the flow guide 220.

[0063] In some embodiments of this application, such as Figure 10As shown, a first clearance groove 220c is provided on the side of the flow guide 220 near the side frame, and the first clearance groove 220c is used to accommodate the side frame. The flow guide 220 is located outside the lower frame 130, which inevitably occupies the space between the side frame and the lower frame 130, and will interfere with the installation of the lower frame 130. In this regard, this application provides a first clearance groove 220c on the side of the flow guide 220 near the side frame, and the first clearance groove 220c can be used to accommodate the lower end of the lower frame 130.

[0064] Optionally, the first clearance groove 220c also extends through the side of the guide portion 220 opposite to the blocking portion 210 and the side of the panel 1311 facing the lower frame 130. The first clearance groove 220c is set in the form of a notch, so that when there is a positional deviation between the lower end of the side frame and the first clearance groove 220c or the lower end of the side frame is larger than the size of the first clearance groove 220c, the lower end of the side frame can also be inserted into the first clearance groove 220c.

[0065] In some embodiments of this application, such as Figure 8 As shown, the blocking portion 210 has a tapered section 211 on the side opposite to the guide portion 220. The tapered section 211 guides the insertion of the blocking portion 210, facilitating its insertion into the mounting cavity 130a through the opening of the lower frame 10. It can be understood that the cross-sectional area of ​​the tapered section 211 gradually decreases along the direction from the guide portion 220 to the blocking portion 210.

[0066] Optionally, the surface of the tapered section 211 is provided with a slope or a curved surface.

[0067] The mounting cavity 130a based on the lower frame 10 is composed of a first cavity 131a and a second cavity 132a. Correspondingly, in some embodiments of this application, such as Figures 8 to 10 As shown, the blocking portion 210 includes a first blocking portion 212 and a second blocking portion 213 arranged sequentially along the height direction of the frame body 100. The first blocking portion 212 is interference-fitted with the inner surface of the second cavity 132a, and the second blocking portion 213 abuts against at least the first inner surface 132b of the first cavity 131a at the height of the frame body 100. The first inner surface 132b is close to the touch panel 20 (see...). Figure 6 The guide portion 220 is connected to at least one of the first blocking portion 212 and the second blocking portion 213. The waterproof component 200 can be fixed to the lower frame 130 by inserting the first blocking portion 212 into the mounting cavity 130a of the lower frame 130 with an interference fit. As an example, the second blocking portion 213 only abuts against the first inner surface 132b of the second cavity 132a at the height of the frame body 100; that is, the second blocking portion 213 does not completely fill the first cavity 131a at the height of the frame body 100 (see...). Figure 7 ).

[0068] Optionally, such as Figure 8 As shown, a second clearance groove 212a is provided on the side of the first blocking portion 212 near the filter strip 132, and the second clearance groove 212a is used to accommodate the filter strip 132. The arrangement of the first blocking portion 212 also affects the assembly of the filter strip 132. To address this, this application provides a second clearance groove 212a on the first blocking portion 212 to accommodate the filter strip 132. Optionally, the second clearance groove 212a also extends through the side of the first blocking portion 212 near the touch panel 20 and the side near the side frame. By setting the second clearance groove 212a in the form of a notch, when there is a positional deviation between the end of the filter strip 132 and the second clearance groove 212a, or when the end size of the filter strip 132 is larger than the size of the second clearance groove 212a, the end of the filter strip 132 can still be inserted into the second clearance groove 212a.

[0069] Furthermore, in one embodiment, as Figures 8 to 10 As shown, the guide portion 220 includes a first guide portion 221 and a second guide portion 222 arranged sequentially along the height direction of the frame body 100. The first guide portion 221 is connected to the first blocking portion 212, and the second guide portion 222 is connected to the second blocking portion 213. Connecting the guide portion 220 to the first blocking portion 212 and the second blocking portion 213 increases the connection strength between the guide portion 220 and the blocking portion 210, and also increases the contact area between the guide portion 220 and the lower frame 130, thereby further improving the blocking effect of the guide portion 220 on water accumulation at the corners of the frame. Of course, in some other embodiments, the guide portion 220 may only be connected to the first blocking portion 212, or only to the second blocking portion 213.

[0070] Optionally, a component mounting position 220d is provided on the side of the second guide portion 222 near the first blocking portion 212. The component mounting position 220d is located between the first inner surface 132b and the second inner surface 132c of the second cavity 132a, with the second inner surface 132c opposite to the first inner surface 132b (see [reference]). Figure 6 Infrared emitting and receiving sensing elements are typically integrated onto a circuit board. During installation, the circuit board can be mounted on the component mounting position 220d, that is, the waterproof component 200 at the left and right ends of the lower frame 130 is used to mount the circuit board, eliminating the need for additional mounting components and simplifying the structure of the frame 10. In addition, by providing the component mounting position 220d on the second guide portion 222, the second blocking portion 213 only needs to abut against the first inner surface 132b of the first cavity 131a, without needing to abut against the second inner surface 132c of the first cavity 131a. This reduces the compatibility between the waterproof component 200 and the lower frame 130 and reduces the processing difficulty of the waterproof component 200.

[0071] Optionally, the second flow guide 222 has a mounting slot at the component mounting position 220d. The circuit board can be inserted into the mounting slot, which facilitates the installation and removal of the circuit board.

[0072] Optionally, see Figure 8 and Figure 10 The first guide section 221 has a smaller dimension in the thickness direction of the frame body 100 than the second guide section 222 in the thickness direction of the frame body 100, so that the guide section 220 forms a two-layer stepped structure. This arrangement facilitates the drainage of water accumulated at the left and right ends of the frame.

[0073] On the other hand, such as Figure 1 As shown, another embodiment of this application provides a display device, which includes a touch panel 20, a display screen, and a frame 10 as described in any of the above claims. The lower border 130 and side borders of the frame 10 are connected and surround the outer periphery of the touch panel 20, and the display screen is disposed on the back side of the touch panel 20. As an example, the display screen is attached to the back of the touch panel 20, or the display screen is spaced apart on the back side of the touch panel 20.

[0074] This display device can be the main screen of a smart blackboard, or it can be any other display device with a bottom bezel of 130mm that requires the installation of infrared transmitting and receiving sensing elements and other components.

[0075] When water accumulates in the center or edge of the touch panel 20, the water can flow into the corners of the lower frame 130. The blocking part 210 can prevent the water from flowing from the opening of the lower frame 130 into the mounting cavity 130a of the lower frame 130. The guide part 220 can also guide the water accumulated at the left and right ends of the lower frame 130, so that the water at the left and right ends of the frame can flow out of the frame 10 quickly, avoiding accumulation at the left and right ends of the lower frame 130. This can effectively waterproof the lower frame 130 and prevent corrosion of components such as infrared emitting elements inside the lower frame 130. In addition, the waterproof component 200 can be fixed to the lower frame 130 by its own blocking part 210, without the need for additional mounting parts for installation and fixation, which simplifies the structure of the frame 10.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
