Description

Technical Field

[0001] This utility model relates to the field of guidance signs, specifically an underground embedded platform guidance sign. Background Technology

[0002] Platform signs are used to guide passengers to the correct platform or vehicle. They are typically installed on platforms of public transportation systems (such as subways, train stations, and light rail stations). Platform signs usually display information such as platform number, route, direction, and vehicle arrival time to help passengers accurately find the vehicle or route they need. These signs are usually presented in the form of text, images, or symbols, aiming to provide clear and easy-to-understand information to facilitate smooth passenger boarding. Currently used platform signs are adjustable in brightness to adapt to different lighting conditions. Adjustable brightness signs can be adjusted according to actual lighting conditions to ensure clear visibility in both bright and dim environments, helping passengers accurately obtain information.

[0003] To facilitate better guidance and save space, some guidance signs, such as those in subway, train stations, and light rail stations, are currently embedded in the ground. However, this causes the signs to generate heat after prolonged use. Because the signs are embedded in the ground, the heat cannot be dissipated, thus affecting their lifespan. Therefore, this paper proposes an underground embedded platform guidance sign to address the above-mentioned problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and to facilitate better guidance and save space, some guidance signs, such as those in subway, train stations, and light rail stations, are currently embedded in the ground. However, this causes the guidance signs to generate heat after prolonged use. Because the signs are embedded in the ground, the heat cannot be dissipated, which affects the lifespan of the guidance signs. This utility model proposes an underground embedded platform guidance sign.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The underground embedded platform guide sign of this utility model includes an embedded shell, a partition fixed at one end of the embedded shell, a heat dissipation groove and an installation groove on both sides of the partition, an electronic guide sign body detachably installed in the installation groove, an installation frame fixedly sleeved on the outer side of the display screen of the electronic guide sign body, a heat sink fixedly installed at the bottom of the installation groove, the upper surface of the heat sink being attached to the back of the electronic guide sign body, heat dissipation holes are opened on both sides of the partition, a fan for heat dissipation is installed in both sets of heat dissipation holes, and a filter plate is fixedly installed on the upper surface of the heat dissipation groove.

[0006] Preferably, the mounting groove has embedded steps on the opposite two side surfaces, and the mounting frame is embedded in the two embedded steps.

[0007] Preferably, the upper surface of the mounting frame has multiple countersunk holes on both embedded step portions, and each of the multiple countersunk holes is provided with countersunk screws for fixing the mounting frame. One end of each of the multiple countersunk screws passes through the countersunk hole and is locked to the upper surface of the embedded step.

[0008] Preferably, rubber pads are fixed on the upper surfaces of both embedded steps, and two sets of rubber blocks are fixed on the opposite two sides of the mounting groove.

[0009] Preferably, a rotating rod is rotatably mounted between the opposite two side surfaces inside the heat dissipation groove. One end of the rotating rod passes through the partition and into the mounting groove. Three sets of air guide plates for auxiliary heat dissipation are fixedly distributed in a ring array on the rotating rod.

[0010] Preferably, a motor for driving the rotating rod is installed in the mounting slot, and the motor is mounted on one side surface of the partition located at the rotating rod.

[0011] The advantages of this utility model are:

[0012] 1. This utility model solves the problem of heat generation in electronic guide signs by first creating an embedding groove in the ground and then embedding the housing within it, making the display surface of the electronic guide sign horizontal with the ground. When the electronic guide sign is working, the heat sink absorbs the heat generated, and the fan in the heat dissipation hole operates to ventilate the mounting groove, expelling heat from the internal space and lowering the internal temperature to improve heat dissipation. The expelled heat enters the heat dissipation groove and is then discharged to the outside through the filter holes on the filter plate. The filter plate prevents impurities from falling into the heat dissipation groove, thus solving the problem of heat generation after prolonged operation of the guide sign. Because the guide sign is embedded in the ground, the heat cannot be dissipated, which affects the service life of the guide sign.

[0013] 2. This utility model uses an embedded step to limit the mounting frame within the mounting groove, allowing the bottom of the electronic guide sign body to suspend within the groove. This facilitates the installation and heat dissipation of the electronic guide sign body. After embedding the mounting frame into the embedded step, the countersunk screws in the countersunk holes are tightened to fix the electronic guide sign body onto the mounting groove, facilitating installation and fixation. Rubber pads and blocks provide a shock-absorbing layer between the electronic guide sign body and the embedded shell, improving the protection of the electronic guide sign body. By driving the rotating rod to rotate, it causes three sets of air guide plates to swing. When the exhausted hot air enters the heat dissipation groove, it is discharged to the outside through the air guide plates, thus achieving the purpose of heat dissipation. Starting the motor drives the rotating rod to rotate, thereby achieving the purpose of electric heat dissipation. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figures 1-3 As shown, an underground embedded platform guide sign includes an embedded shell 1. A partition 4 is fixed at one end of the embedded shell 1. The partition 4 has a heat dissipation groove 3 and a mounting groove 2 on both sides. An electronic guide sign body 8 is detachably installed in the mounting groove 2. A mounting frame 14 is fixedly fitted on the outer side of the display screen of the electronic guide sign body 8. A heat sink 9 is fixedly installed at the bottom of the mounting groove 2. The upper surface of the heat sink 9 is attached to the back of the electronic guide sign body 8. Heat dissipation holes 5 are opened on both sides of the partition 4. A fan 6 for heat dissipation is installed in each of the two sets of heat dissipation holes 5. A filter plate 7 is fixedly installed on the upper surface of the heat dissipation groove 3.

[0021] During operation, an embedding groove is first created in the ground during installation, and then the embedding shell 1 is embedded in it, so that the display surface of the electronic guide sign body 8 is horizontal with the ground. When the electronic guide sign body 8 is working, the heat sink 9 can absorb the heat generated by it. At the same time, the fan 6 in the heat dissipation hole 5 will work to ventilate the mounting groove 2, exhaust the heat in the internal space, reduce the temperature of the internal space and improve the heat dissipation effect. The exhaust heat will enter the heat dissipation groove 3, and then be discharged to the outside through the filter holes on the filter plate 7. The filter plate 7 can prevent impurities from falling into the heat dissipation groove 3, thus solving the problem that the guide sign will generate heat after long-term operation. Because the guide sign is embedded in the ground, the heat cannot be dissipated, which will affect the service life of the guide sign.

[0022] Furthermore, the mounting groove 2 has embedded steps 13 on the opposite two side surfaces, and the mounting frame 14 is embedded in the two embedded steps 13.

[0023] During operation, the step 13 can limit the mounting frame 14 within the mounting groove 2, so that the bottom of the electronic guide sign body 8 will be suspended in the mounting groove 2, thereby facilitating the installation and heat dissipation of the electronic guide sign body 8.

[0024] Furthermore, the upper surface of the mounting frame 14 is provided with multiple countersunk holes 15 on the two embedded steps 13. Each of the multiple countersunk holes 15 is provided with countersunk screws 16 for fixing the mounting frame 14. One end of each of the multiple countersunk screws 16 passes through the countersunk hole 15 and is locked to the upper surface of the embedded step 13.

[0025] During operation, after the mounting frame 14 is embedded in the embedded step 13, the countersunk screws 16 in the countersunk hole 15 are all tightened, thereby fixing the electronic guide sign body 8 on the mounting groove 2, which facilitates installation and fixation.

[0026] Furthermore, rubber pads 17 are fixed to the upper surfaces of both embedded steps 13, and two sets of rubber blocks 18 are fixed to the opposite two sides of the mounting groove 2.

[0027] During operation, the rubber pad 17 and rubber block 18 create a shock-absorbing layer between the electronic guide plate body 8 and the embedded shell 1, which improves the protection of the electronic guide plate body 8.

[0028] Furthermore, a rotating rod 10 is rotatably installed between the opposite two side surfaces inside the heat dissipation groove 3. One end of the rotating rod 10 passes through the partition 4 into the mounting groove 2. Three sets of air guide plates 11 for auxiliary heat dissipation are fixedly distributed in a ring array on the rotating rod 10.

[0029] During operation, the rotating rod 10 is driven to rotate, causing the three sets of air guide plates 11 to swing. When the hot air is discharged into the heat dissipation tank 3, it is discharged to the outside through the air guide plates 11, thereby achieving the purpose of dissipating heat.

[0030] Furthermore, a motor 12 for driving the rotating rod 10 is installed in the mounting slot 2. The motor 12 is mounted on one side surface of the partition 4 at the rotating rod 10.

[0031] When in operation, starting the motor 12 will drive the rotating rod 10 to rotate, thereby achieving the purpose of electrically dissipating heat.

[0032] Working principle: During installation, an embedding groove is first opened in the ground, and then the embedding shell 1 is embedded in it, so that the display surface of the electronic guide sign body 8 is horizontal with the ground. When the electronic guide sign body 8 is working, the heat sink 9 can absorb the heat generated by it. At the same time, the fan 6 in the heat dissipation hole 5 will work to ventilate the mounting groove 2, exhaust the heat in the internal space, reduce the temperature of the internal space and improve the heat dissipation effect. The exhaust heat will enter the heat dissipation groove 3, and then be discharged to the outside through the filter holes on the filter plate 7. The filter plate 7 can prevent impurities from falling into the heat dissipation groove 3. This solves the problem that the guide sign will generate heat after long-term operation. Because the guide sign is embedded in the ground, the heat cannot be dissipated, which will affect the service life of the guide sign.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
