Description

Technical Field

[0001] This application relates to the field of wireless communication equipment technology, and in particular to a split-type wireless base station with a heat dissipation structure. Background Technology

[0002] With the continuous development of wireless communication technology, wireless base stations, as an important infrastructure of communication networks, are of paramount importance in terms of the rationality of their internal structure and the ease of installation and maintenance.

[0003] In existing wireless base stations, the internal mounting racks are usually fixed, and the spacing between the mounting racks is difficult to adjust flexibly according to the size and installation requirements of different electrical components. This may result in insufficient space when installing some electrical components of special size, affecting the normal installation and layout of the equipment.

[0004] Furthermore, since the mounting bracket is fixed inside the base station, operators need to operate within the limited space inside the base station when installing electrical components. The narrow operating space not only increases the difficulty of installation and reduces the efficiency of installation, but also makes it easy for electrical components to be installed improperly or damaged due to inconvenience of operation. Therefore, a split-type wireless base station with a heat dissipation structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a split-type wireless base station with a heat dissipation structure to solve the problems mentioned in the background art.

[0006] The split-type wireless base station with a heat dissipation structure provided in this application adopts the following technical solution:

[0007] A split-type wireless base station with a heat dissipation structure includes a base station housing and a door hinged to the outer wall of the front of the base station housing. Multiple mounting plates are installed inside the base station housing. The outer walls of the two sides of the mounting plates are slidably connected to guide rails. A limit mechanism is provided on the bottom outer wall of the guide rails. A fixing plate is fixedly connected to one end of each pair of guide rails facing the inside of the base station housing. A pitch-changing mechanism for driving the multiple fixing plates to move is provided on the outer wall of the base station housing.

[0008] The pitch-changing mechanism includes short connecting rods and long connecting rods. The two sets of short connecting rods are rotatably connected to the outer walls of the uppermost and lowermost fixed plates, respectively. There are multiple sets of long connecting rods, with the ends of each set of long connecting rods hinged to each other and their upper and lower ends hinged to the two sets of short connecting rods, respectively. The middle sections of the multiple sets of long connecting rods are hinged to the outer walls of the middle fixed plates. The long connecting rods include connecting rod one and connecting rod two that are arranged in a cross manner.

[0009] Preferably, the pitch-changing mechanism further includes a bracket, a first bevel gear, a second bevel gear, and a third bevel gear. The bracket is fixedly connected to the inner wall of the base station housing. The first and second bevel gears are rotatably connected to the outer wall of the bracket. The third bevel gear is fixedly connected to the outer wall of the middle section of a connecting rod located in the middle. The third bevel gear and the first bevel gear are both meshed with the second bevel gear.

[0010] Preferably, a rotating shaft is fixedly connected to the outer wall of the first bevel gear. The end of the rotating shaft away from the first bevel gear passes through the third bevel gear and the second connecting rod in sequence, and is fixedly connected to the middle section of the outer wall of the first connecting rod located in the middle. A servo motor is fixedly installed on the bottom outer wall of the bracket. The end of the output shaft of the servo motor passes through the bracket and is fixedly connected to the second bevel gear.

[0011] Preferably, the limiting mechanism includes two fixed rods fixedly connected to the outer wall of the bottom of the guide rail. The outer walls of the two fixed rods are slidably connected to a movable block. A locking block is fixedly connected to the outer wall of the movable block on the side facing the guide rail. The outer wall of the mounting plate has multiple locking holes. The end of the locking block away from the movable block passes through the guide rail and engages with the locking hole.

[0012] Preferably, the limiting mechanism further includes a fixing frame fixedly connected to the bottom outer wall of the guide rail, the end of the fixing rod away from the guide rail being fixedly connected to the outer wall of the fixing frame, a spring being sleeved on the outer wall of the fixing rod, the spring being located between the movable block and the fixing frame, and a handle being fixedly connected to the bottom outer wall of every two movable blocks.

[0013] Preferably, multiple slide rails are welded to the outer walls of both sides of the base station housing, and the multiple guide rails are slidably connected to the slide rails by sliders, wherein two guide rails located in the middle section of the base station housing are fixedly connected to the multiple slide rails by fixing blocks.

[0014] Preferably, a cooling fan is installed on the top outer wall of the base station housing, and heat dissipation holes are provided on the two outer walls near the bottom of the base station housing.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. Through the variable pitch mechanism, including short connecting rods, long connecting rods, bevel gears and rotating shafts, driven by a servo motor, the spacing between multiple mounting plates can be flexibly adjusted. Unlike the existing fixed-spacing mounting brackets, this design can be adjusted according to the size and installation requirements of different electrical components, effectively avoiding the problem of insufficient space when installing electrical components of special sizes, greatly improving the utilization rate of the base station's internal space, and ensuring the normal installation and reasonable layout of the equipment;

[0017] 2. Through the cooperation of the limiting mechanism, guide rail, and mounting plate, when electrical components need to be installed, the mounting plate can be pulled out from the guide rail and fixed, providing operators with a more spacious operating space. This changes the situation in the prior art where operators have to operate in the confined space inside the base station. This not only significantly reduces the installation difficulty and improves the installation efficiency, but also effectively reduces the situation where electrical components are not installed properly or are damaged due to inconvenient operation, thus ensuring the installation quality and service life of electrical components.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] This application discloses a split-type wireless base station with a heat dissipation structure. (Refer to...) Figure 1-7A split-type wireless base station with a heat dissipation structure includes a base station housing 1 and a door 2 hinged to the front outer wall of the base station housing 1. The base station housing 1 serves as the main load-bearing body of the entire base station and adopts a split design for easy transportation and installation. The door 2 is hinged to the front outer wall of the base station housing 1 and can be opened and closed via a hinge, facilitating the installation, maintenance, and repair of the equipment inside the base station. A sealing strip is provided at the contact point between the door 2 and the base station housing 1 to ensure the airtightness of the base station and prevent dust, moisture, etc. from entering.

[0028] Multiple mounting plates 9 are installed inside the base station housing 1. The mounting plates 9 are used to install various electrical components, such as communication modules and power modules. The outer walls on both sides of the mounting plates 9 are slidably connected to the guide rails 8. Specifically, the mounting plates 9 are provided with sliding grooves that are adapted to the guide rails 8 on both sides, so that the mounting plates 9 can slide smoothly along the guide rails 8. A fixing plate 10 is fixedly connected to one end of every two guide rails 8 facing the inside of the base station housing 1. The fixing plate 10 is used to connect and fix the guide rails 8 to ensure the stability of the guide rails 8.

[0029] The pitch-changing mechanism is used to drive multiple fixed plates 10 to move, thereby adjusting the spacing between the mounting plates 9 to accommodate the installation requirements of electrical components of different sizes. The pitch-changing mechanism includes short connecting rods 19, long connecting rods 20, a bracket 21, a first bevel gear 22, a second bevel gear 23, a third bevel gear 24, and a rotating shaft 25. Two sets of short connecting rods 19 are rotatably connected to the outer walls of the uppermost and lowermost fixed plates 10, respectively. The long connecting rods 20 include multiple sets, with the ends of each set of long connecting rods 20 hinged to each other, and their upper and lower ends respectively hinged to the two sets of short connecting rods 19. The middle sections of the multiple sets of long connecting rods 20 are hinged to the outer walls of the middle fixed plates 10. The long connecting rods 20 include connecting rod one 201 and connecting rod two 202 arranged intersecting each other. When the short connecting rods 19 rotate, they will drive the long connecting rods 20 to move, thereby changing the spacing between the fixed plates 10.

[0030] The bracket 21 is fixedly connected to the inner wall of the base station housing 1. The first bevel gear 22 and the second bevel gear 23 are rotatably connected to the outer wall of the bracket 21. The third bevel gear 24 is fixedly connected to the outer wall of the middle section of a connecting rod 202 located in the middle. The third bevel gear 24 and the first bevel gear 22 are both meshed with the second bevel gear 23. The bracket 21 serves to support and fix the bevel gears.

[0031] A rotating shaft 25 is fixedly connected to the outer wall of the first bevel gear 22. The end of the rotating shaft 25 away from the first bevel gear 22 passes through the third bevel gear 24 and the second connecting rod 202 in sequence and is fixedly connected to the outer wall of the middle section of the first connecting rod 201 located in the middle. A servo motor 11 is fixedly installed on the bottom outer wall of the bracket 21. The end of the output shaft of the servo motor 11 passes through the bracket 21 and is fixedly connected to the second bevel gear 23. When the servo motor 11 is started, it drives the second bevel gear 23 to rotate. The second bevel gear 23 drives the first bevel gear 22 and the third bevel gear 24 to rotate at the same time. The first bevel gear 22 drives the first connecting rod 201 to move through the rotating shaft 25. The third bevel gear 24 drives the second connecting rod 202 to move, thereby causing the long connecting rod 20 and the short connecting rod 19 to move, thereby realizing the adjustment of the spacing of the fixed plate 10.

[0032] The limiting mechanism is used to limit and fix the mounting plate 9 after it has slid to a suitable position, so as to ensure the stability of the mounting plate 9. The limiting mechanism includes a fixed rod 13, a movable block 14, a locking block 15, a spring 16, a fixing frame 17, and a handle 18.

[0033] Two fixed rods 13 are fixedly connected to the outer wall of the bottom of the guide rail 8. The outer walls of the two fixed rods 13 are slidably connected to the movable block 14, and the movable block 14 can move linearly along the fixed rods 13.

[0034] A locking block 15 is fixedly connected to the outer wall of the movable block 14 facing the guide rail 8. Multiple locking holes 12 are opened on the outer wall of the mounting plate 9. The end of the locking block 15 away from the movable block 14 passes through the guide rail 8 and is locked in the locking hole 12. When it is necessary to fix the mounting plate 9, the locking block 15 is inserted into the corresponding locking hole 12 to achieve the limit.

[0035] The end of the fixed rod 13 away from the guide rail 8 is fixedly connected to the outer wall of the fixed frame 17. A spring 16 is sleeved on the outer wall of the fixed rod 13. The spring 16 is located between the movable block 14 and the fixed frame 17. When the spring 16 is in a compressed state, it will give the movable block 14 a push towards the guide rail 8, so that the locking block 15 is more firmly locked in the locking hole 12.

[0036] A handle 18 is fixedly connected to the bottom outer wall of each pair of movable blocks 14. When it is necessary to adjust the position of the mounting plate 9, pull the handle 18 to overcome the elastic force of the spring 16 and make the locking block 15 disengage from the locking hole 12. At this time, the mounting plate 9 can slide along the guide rail 8.

[0037] Multiple slide rails 5 are welded to the outer walls of both sides of the base station housing 1. Multiple guide rails 8 are slidably connected to the slide rails 5 via sliders 6. The sliders 6 are fixed to the side of the guide rails 8 and are adapted to the slide rails 5 to ensure that the guide rails 8 can slide smoothly on the slide rails 5. One of the guide rails 8 located in the middle section of the base station housing 1 is fixedly connected to the outer wall of the multiple slide rails 5 via a fixing block 7. After the fixing block 7 fixes the two guide rails 8 in the middle, the multiple guide rails 8, the mounting plate 9, and the fixing plate 10 can be stably installed on the multiple slide rails 5 through a pitch-changing mechanism.

[0038] A cooling fan 3 is installed on the top outer wall of the base station housing 1. Heat dissipation holes 4 are opened on the two outer walls near the bottom of the base station housing 1. When the cooling fan 3 is working, it draws out the hot air inside the base station housing 1, and the cold air from the outside enters the base station housing 1 through the heat dissipation holes 4, forming air convection and realizing heat dissipation for the equipment inside the base station.

[0039] The implementation principle of a split-type wireless base station with a heat dissipation structure in this application embodiment is as follows: The servo motor 11 is started, which drives the second bevel gear 23 to rotate. The second bevel gear 23 drives the first bevel gear 22 and the third bevel gear 24 to rotate. The first bevel gear 22 drives the first connecting rod 201 to move through the rotating shaft 25, and the third bevel gear 24 drives the second connecting rod 202 to move. This causes the long connecting rod 20 and the short connecting rod 19 to move. The movement of the short connecting rod 19 and the long connecting rod 20 drives the fixed plate 10 to move, thereby adjusting the spacing between the mounting plates 9 until a suitable installation space is achieved.

[0040] Pull the handle 18 down to move the movable block 14 down on the fixed rod 13, causing the locking block 15 to disengage from the locking hole 12, and pull the mounting plate 9 out of the guide rail 8. Release the handle 18, and the spring 16 will drive the locking block 15 to engage with the corresponding fixed position of the mounting plate 9 after it is pulled out, thus fixing the mounting plate 9 for the installation of electrical components. After the electrical components are installed, push the mounting plate 9 closer to the guide rail 8. The locking hole 12 and the inclined surface at the top of the locking block 15 will press down on the locking block 15 to compress the spring 16. When the mounting plate 9 is reset, the locking hole 12 and the locking block 15 will correspond. Under the elastic force of the spring 16, the locking block 15 will re-engage with the locking hole 12, thus fixing the mounting plate 9 on the guide rail 8 inside the base station housing 1.

[0041] During base station operation, cooling fan 3 works continuously to extract hot air from base station housing 1, while cold air from the outside enters the base station housing 1 through cooling holes 4, forming air convection and reducing the temperature of the equipment inside the base station.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
