In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] Please refer to Figures 1 to 5 The utility model proposes an outdoor digital display and guidance device 100, comprising: a control mainboard 11, a display module 13 and a protective shell 12, wherein the display module 13 is mounted on the control mainboard 11, the control mainboard 11 and the protective shell 12 are detachably connected, and an avoidance hole 125 is opened at a position of the protective shell 12 corresponding to the display module 13, and the avoidance hole 125 includes a first hole edge 125a extending in a direction close to the ground; a plurality of sealing components are convexly provided on one side where the protective shell 12 is connected to the control mainboard 11, and the sealing components include a plurality of sealing strips 121 located on the first hole edge 125a; an end of the sealing strip 121 away from the avoidance hole 125 is lower than an end of the sealing strip 121 close to the avoidance hole 125.

[0025] The protective shell 12 of the outdoor digital display and guidance device 100 is detachably connected to the control main board 11, which is convenient for quick maintenance of the display module 13 for long-term use in outdoor environments. The detachable design also facilitates assembly, maintenance and replacement of various components. A plurality of sealing strips 121 are provided on the side where the protective shell 12 is connected to the control main board 11, and the ends of the sealing strips 121 have different heights, and the height toward the outside is lower, which is conducive to the drainage of rainwater and debris to the outside, ensuring that the internal components are protected in harsh outdoor environments, thereby extending the service life of the equipment and taking into account the convenient maintenance function and waterproof performance.

[0026] At the same time, the elastic sealing strip 121 allows the control mainboard 11 and the display module 13 to be firmly installed in the protective shell 12 to prevent damage caused by impact or vibration.

[0027] Specifically, the sealing strips 121 are arranged at intervals and disposed at two opposite ends of the protective shell 12 , and the arrangement direction of the plurality of sealing strips 121 at each end is perpendicular to the installation plane of the outdoor digital display guiding device 100 .

[0028] In the external environment, impurities such as rainwater enter the gap between the control main board 11 and the protective shell 12 from the top of the outdoor digital display guide device 100, that is, the source direction of the external impurities mainly enters the device from the vertical direction. The sealing strips 121 are arranged at intervals and perpendicular to the installation plane. The sealing strips 121 can effectively block the vertical direction and guide the impurities to the outside, thereby more effectively sealing the joints of the device and improving the waterproof ability of the device.

[0029] At the same time, sealing strips 121 are provided at opposite ends of the protective shell 12 to more evenly disperse external pressure and impact, thereby improving the overall structural stability and durability of the protective shell 12. The spacing of the sealing strips 121 facilitates air circulation and may help dissipate heat inside the device, thereby preventing the device from overheating and improving its working efficiency and lifespan.

[0030] In this embodiment, each sealing strip 121 is extended along a straight line, effectively guiding the impurities to slide along the extension direction and be introduced to the outside.

[0031] In one embodiment, each sealing strip 121 is curved, and the curvature direction is away from the installation plane of the outdoor digital display guide device 100. The curved shape requires liquid, dust and other pollutants to pass through a longer and more complicated path when trying to penetrate along the sealing strip 121, and the curvature direction is away from the installation plane, that is, the arched part faces upward, which effectively increases the curvature of the sealing strip 121 in contact with the impurities, increases the dynamic potential energy of the impurities, and facilitates the impurities to slide off, thereby increasing the difficulty of penetration and improving the sealing effect.

[0032] Furthermore, a guide strip is protruding from one end of the protective shell 12 away from the installation plane. The guide strip includes two extending ends that are inclined in opposite directions. The lower part of each extending end extends toward the outside of the protective shell 12, and each extending end extends to a position close to the sealing strip 121.

[0033] The design of the guide strip helps to guide rainwater or other liquids to drain or to the position of the sealing strip 121, and then the sealing strip 121 guides the rainwater to drain, thereby preventing water from penetrating into the device along the sealing strip 121 or other joints, thereby improving the waterproof performance of the device. The design of the extension end in the opposite direction of the tilt ensures that the liquid can be quickly drained, thereby avoiding corrosion or damage caused by water retention.

[0034] Please refer to Figure 3 and Figure 4 In order to realize the detachable connection between the protective shell 12 and the control main board 11, at least four card connection cavities 122 are opened on the side of the protective shell 12 facing the control main board 11, and a plurality of spaced sealing strips 121 are arranged between two adjacent card connection cavities 122. The control main board 11 is provided with at least four card connection parts, and each card connection part is plugged into and matched with each card connection cavity 122 one by one.

[0035] Through the design of the clips and the clip cavity 122, the protective shell 12 and the control main board 11 can be quickly disassembled and assembled. No additional tools or fasteners are required, the operation is simple, and the efficiency of installation and maintenance is improved. When the clip of the control main board 11 is plugged into the clip cavity 122, the control main board 11 compresses the sealing strip 121 to achieve a seal between the two. The plug-in cooperation of at least four clips and the clip cavity 122 ensures a firm connection between the protective shell 12 and the control main board 11, prevents loosening or falling off, and ensures the stability and safety of the equipment. The uniform distribution of multiple clips can effectively disperse the external pressure, enhance the structural stability of the entire equipment, and avoid deformation or damage due to single-point force.

[0036] The snap-on design reduces the use of mechanical fasteners such as screws, avoids possible stress concentration and material fatigue at the screw holes, and thus improves the durability and service life of the equipment. The detachable connection design makes it easier to maintain and replace internal components, reduces downtime, improves equipment maintenance efficiency, and reduces maintenance costs.

[0037] For further information, please refer to Figure 5 Each clamping cavity 122 is provided with two spring pieces 123, and the two spring pieces 123 enclose and form a plug hole 124 for plugging and matching with a clamping piece. The spring piece 123 is made of a material with good elasticity, such as metal or high-strength plastic, and has good durability and fatigue resistance, and can maintain good elasticity and clamping force during long-term use.

[0038] The two spring pieces 123 form an interference fit with the card connector, and the two spring pieces 123 provide a strong clamping force to ensure that the card connector can be firmly fixed in the card connector cavity 122 after insertion to prevent loosening or falling off, thereby improving the overall stability of the device. The double fixing structure helps to tightly combine the protective shell 12 and the control motherboard 11, reduce gaps, improve the sealing performance of the device, and prevent impurities such as water and dust from entering the interior of the device.

[0039] In this embodiment, the control main board 11 is provided with a plurality of through holes 111 corresponding to the plurality of jacks 124, and the card connector is provided separately, and the card connector is plugged into the through holes 111 and the jacks 124 at the same time to realize the connection and cooperation between the control main board 11 and the protective shell 12. With such a configuration, the PCB board portion of the control main board 11 does not need to be provided with a special structure separately, and only needs to be implemented by using a PCB board of a public mold, which reduces the manufacturing difficulty and improves the manufacturing efficiency of the outdoor digital display and guidance device 100.

[0040] Please refer to Figure 1 and Figure 2 The control main board 11 is provided with a plurality of signal interfaces for data transmission after the maintenance personnel open the protective shell 12, and the transmitted data provides display content for the display module 13. In order to avoid the display module 13, the size of the avoidance hole 125 opened in the protective shell 12 is the same as the size of the display screen of the display module 13, and a sealing belt is arranged between the display module 13 and the hole wall of the avoidance hole 125 to block the gap between the display module 13 and the protective shell 12, thereby improving the sealing performance of the outdoor digital display guide device 100.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
