[0037] See also Figures 1 to 9 , this embodiment provides a display fixing structure, including a frame groove 10, a display screen 20, a circuit board 30 and a fastener 40. The display screen can be LCD or OLED. The frame groove 10 is surrounded on all sides, with a full opening on the back and a partial opening on the front. The opening on the front is used to reserve a display observation window for the display screen 20, and its size is not less than the display area of ​​the display screen 20, and the opening position matches the display screen 20. For the convenience of explanation, the front side of this description refers to the side on the same side as the display surface of the display screen 20, and the back side is the opposite side. Based on this, the side where the circuit board 30 is fixedly connected to the fastener 40 is the lower side, and the corresponding other side is the upper side, and the left and right sides are perpendicular to the upper and lower sides. As shown in the attached Figure 1As shown, a plane frame of a certain width is left around the front of the frame groove 10, and its function is to limit the display screen 20 in the front direction, and a first limiting portion 101 is provided on the upper side of the frame groove 10, and the function of the first limiting portion 101 is to limit the display screen 20 in the upward direction. Preferably, the first limiting portion 101 is an inverted L-shaped structure, which further limits the display screen 20 in the back direction. A second limiting portion 102 and a third limiting portion 103 are provided on the left and right sides respectively, and the side wall of the second limiting portion 102 is used to limit the display screen 20 in the lateral direction, and the top surface of the second limiting portion 102 is used to cooperate with the bottom surface of the third limiting portion 103 to limit the front and back directions of the circuit board 30, that is, the two side edges of the circuit board 30 can be inserted between the second limiting portion 102 and the third limiting portion 103 to achieve the limiting function. The lower side of the groove frame is provided with a plurality of hole columns 105 for detachably fixing with the fastener 40. There are at least two hole columns 105 and they are symmetrically arranged on the left and right sides to achieve stable fixing. The first limiting portion 101, the second limiting portion 102, the hole columns 105 and the bottom of the frame groove 10 enclose a space for accommodating the display screen 20. The third limiting portion 103 is higher than the second limiting portion 102 and the gap between the two can be used for the side edge of the circuit board 30 to be inserted. The front and back sides of the circuit board 30 are limited by the second limiting portion 102 and the third limiting portion 103 respectively, and the left and right sides of the circuit board 30 can be directly limited by the left and right side walls of the frame groove 10. The lower side of the circuit board 30 is provided with a fixing hole 301, and the fastener 40 passes through the fixing hole 301 and is fixedly connected with the hole columns 105. It should be noted that, in the projection perpendicular to the front direction, the range enclosed by the first limiting portion 101, the second limiting portion 102 and the hole column 105 is slightly smaller than the frame range of the frame groove 10, so it is convenient to install the display screen 20 and the circuit board 30 in sequence.

[0038] The display screen 20 is electrically connected to the circuit board 30, and the electrical connection can be achieved through a flat cable, a metal pin or a hot-pressed soft tape. Preferably, a conductive strip 50 is also included, and the display screen 20 and the circuit board 30 are electrically connected through the conductive strip 50. The conductive strip 50 can be a conductive adhesive strip (zebra strip), and the conductive strip 50 is formed by vulcanization after alternately stacking conductive silicone and insulating silicone. The conductive adhesive strip is a conductive adhesive material that is commonly used for connecting the PCB circuit board 30 and the LCD display screen 20. Its working principle is to connect the pins on the circuit board 30 with the pins on the display screen 20 through the conductive adhesive strip, thereby realizing signal transmission and communication. The manufacturing principle of the conductive adhesive strip is to coat a conductive material, such as silver paste or copper paste, on a substrate to form a conductive layer. The thickness of the conductive layer is usually between 10-50 microns, and the resistance value of the conductive adhesive strip can be controlled by adjusting the coating thickness. In addition, the conductive adhesive strip also has good viscosity and can be firmly fixed between the circuit board 30 and the display screen 20 to avoid loosening or falling off during use. When the conductive adhesive strip is used to connect the circuit board 30 and the display screen 20, the conductive adhesive strip needs to be firstly pasted on the corresponding positions of the circuit board 30 and the display screen 20 to ensure that the conductive adhesive strip is in full contact with the pins. Then, the signal is transmitted to the conductive adhesive strip through the pins, and the signal is transmitted to the display screen 20 through the conductive adhesive strip, thereby realizing the connection between the circuit board 30 and the display screen 20.

[0039] The specific working principle of the display fixing structure is as follows: first, the display screen 20 is assembled with the front side facing the frame groove 10. During assembly, the upper edge of the display screen 20 is first pressed against the frame groove 10 and the first limiting portion 101 at the same time, and adjusted to the left and right sides respectively against the side walls of the second limiting portion 102, and then the lower edge of the display screen 20 is pushed into the frame groove 10 and pressed against the upper side of the hole column 105. At this time, the display screen 20 is assembled and is simultaneously limited by the frame groove 10, the first limiting portion 101, the second limiting portion 102 and the hole column 105. That is, The front, upper and lower sides, and left and right sides of the display screen 20 are all fixed. After the display screen 20 is assembled, one conductive end of the conductive strip 50 is fixedly connected to the connecting pin on the back of the display screen 20, and then the left and right sides of the circuit board 30 are respectively inserted between the second limiting portion 102 and the third limiting portion 103 on the left and right side walls of the frame groove 10, and the position of the circuit board 30 is adjusted until the fixing hole 301 is aligned with the hole column 105, and finally the fastener 40 is passed through the fixing hole 301 and fixedly connected to the hole column 105, thereby achieving the overall fixation through the fixing structure on one side (i.e., the lower side). It should be noted that in this embodiment, the position of the conductive strip 50 can be at any position, and it only needs to realize the conductive function, and the conductive strip 50 itself can also play a certain limiting and fixing role, that is, the circuit board 30 fixed by the fastener 40 limits and fixes the display screen 20 through the conductive strip 50.

[0040] In the present invention, a first limiting portion 101, a second limiting portion 102, a third limiting portion 103 and a hole column 105 are arranged on the inner side of the frame groove 10. The display screen 20 is limited by the first limiting portion 101, the second limiting portion 102 and the hole column 105, and the circuit board 30 is limited by the second limiting portion 102 and the third limiting portion 103. At the same time, the fastener 40 passes through the fixing hole 301 on the lower side of the circuit board 30 to be fixedly connected with the hole column 105. The circuit board 30 and the display screen 20 are fixed in the frame groove 10 through the fixing structure on one side. The assembly is simple, the fixing structure is stable, and the production efficiency is improved.

[0041] Furthermore, the display screen 20 is provided with a strip groove 201, the distance between the bottom of the strip groove 201 and the circuit board 30 is slightly smaller than the thickness of the conductive strip 50, and a portion of the conductive strip 50 is inserted into the strip groove 201. The display connection pin on the back of the display screen 20 can be arranged at the bottom of the strip groove 201, and when a portion of the conductive strip 50 is inserted into the strip groove 201, electrical connection can be performed, and at the same time, the conductive strip 50 is limited by the groove wall of the strip groove 201, so that the conductive strip 50 is more stable and not easy to shift, thereby improving the stability of the electrical connection. For the convenience of processing, preferably, the strip groove 201 is arranged at the lower edge of the display screen 20. In this embodiment, the strip groove 201 has only the upper groove wall to limit the conductive bar 50. Conversely, the lower side of the conductive bar 50 can be limited by the side of the hole column 105, so that the hole column 105 is fully and effectively utilized. The display screen 20, the conductive bar 50 and the circuit board 30 are limited or fixed by the hole column 105, which improves the structural utilization rate, optimizes the internal space, saves costs, and facilitates processing and assembly.

[0042] Furthermore, the left and right sides of the circuit board 30 are respectively provided with structural plates 302, and the structural plates 302 are respectively used to be inserted between the second limiting portion 102 and the third limiting portion 103 of the frame groove 10. The structural plate 302 and the circuit board 30 are integrally formed, and the second limiting portion 102, the third limiting portion 103 and the frame groove 10 can be used to achieve limiting fixation through the structural plate 302, which can reduce the overall area of ​​the circuit board 30, and can be narrowed inward at other positions, which can save PCB board materials and reduce costs.

[0043] Furthermore, a fourth limiting portion 104 is included, and the fourth limiting portion 104 is respectively arranged on the left and right sides of the frame groove 10. The fourth limiting portion 104 is used to abut the left and right edges of the display screen 20. The fourth limiting portion 104 can be a plate-like structure, and its plate surface is opposite to and abuts against the left and right sides of the display screen 20. The fourth limiting portion 104 can be arranged at an upper position of the frame groove 10, so as to stably limit and fix the upper part of the display screen 20 and improve stability.

[0044] Furthermore, a plurality of conductive contacts 303 are provided on the back of the circuit board 30. The conductive contacts 303 can realize the function of jumper wires by printing graphite wires, thereby saving costs.

[0045] Furthermore, a plurality of reinforcing ribs are provided on the inner side of the groove frame.

[0046] The present invention also provides a weather station device, which includes a housing 66, a control module 60, and a temperature and humidity detection module 61, an air pressure detection module 62, a power supply module 63, and a control button 64, which are electrically connected to the control module 60, respectively, and also includes a display fixing structure described in any one of the above embodiments, and the groove frame covers the housing 66. The housing 66 and the groove frame can both be made of plastic material, and the two are detachably connected, and the connection method can be a snap connection, a fastener 40 locking connection, etc. The control module 60 can use an MCU microcontroller, such as STM32L151RCT6; the temperature and humidity detection module 61 can use an SHT30 temperature and humidity sensor; the air pressure monitoring module can use an air pressure sensor, model MCP-J10-1001100K or MS5803-01BA, etc. The power supply module 63 can be a battery compartment with a lithium battery, a button battery or a dry battery to realize power supply, or it can be a power management chip, such as LMG3410R050, UCC12050 and other models, which is combined with a charging interface (such as a USB interface) to realize power supply.

[0047] Furthermore, the control button 64 is arranged on the back of the housing 66. Since the weather station device mainly detects and displays meteorological parameters, the control button 64 is arranged on the back of the housing 66 so that the area available for display on the front is larger, so that more content can be displayed, which is convenient for observation. The inner side of the control button 64 can be made of conductive material, which is used in conjunction with the conductive contact 303. By pressing the control button 64, the conductive material and the conductive contact 303 are in contact and conductive, thereby realizing the control operation function.

[0048] Furthermore, a plurality of grill structures 65 are provided on the housing 66. The grill structures 65 allow the external air to fully enter and circulate inside the housing 66, thereby ensuring that the detection results of the temperature and humidity module and the air pressure module are more accurate.

[0049] Furthermore, a plurality of pads are provided on the left and right sides of the display screen. The pads may be made of elastic materials, such as rubber, which can play a buffering role to prevent the side of the display screen from being impacted and cracked, thereby improving safety and extending product life.

[0050] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model.
