Description

Technical Field

[0001] This invention relates to the field of communication base station technology, specifically a mobile communication base station for emergency communication. Background Technology

[0002] A communication base station is a type of radio station. It refers to a radio transceiver station that transmits information between a mobile communication switching center and a mobile phone terminal within a limited radio coverage area. During the reconstruction of disaster areas, communication vehicles are often used to carry emergency communication base stations to disaster areas to temporarily cover signals. The base station on the communication vehicle is usually fixed to the roof of the vehicle with an antenna box, feeder, and RRU by a bracket, taking advantage of the vehicle's height to expand the communication coverage.

[0003] Sometimes, when vehicles pass over fallen power lines or height restriction barriers in disaster areas, the communication base stations installed on the vehicle roof cannot pass through these height-restricted sections. In such cases, it is usually necessary to manually get out of the vehicle to adjust the height of the support bracket for the communication base station or disassemble the bracket, which increases the manpower burden. Furthermore, in the event of sudden hail in disaster areas, hail falling on the antenna box can easily damage it, and most communication base stations lack structures to protect the antenna box. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile communication base station for emergency communication to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A mobile communication base station for emergency communication includes a base plate embedded and fixed to the top of a vehicle. An internally threaded tube is slidably inserted into the top of the base plate. A support cylinder is fixed to the top of the internally threaded tube. Multiple hexagonal shafts are rotatably connected to the outer side of the support cylinder at equal angles. A shaft rod is rotatably connected to the middle of the support cylinder, engaging with two hexagonal shafts. A mounting bracket is slidably sleeved on the outer side of the hexagonal shafts. An antenna box and an RRU are mounted and fixed on the outer side of the mounting bracket. The antenna box and the RRU are connected via a feed line. An L-shaped block is rotatably connected between the ends of two adjacent mounting brackets. A protective mechanism is fixed to the top of the two L-shaped blocks. Two limiting telescopic members are fixed to the top surface of the base plate. The top ends of the limiting telescopic members are rotatably connected to the corresponding hexagonal shafts. An externally threaded tube is screwed into the internally threaded tube. A shaft rod two, slidably engaged with shaft rod one, is rotatably inserted into the internally threaded tube. A drive housing for driving the externally threaded tube and shaft rod two to rotate is provided at the bottom of the externally threaded tube and shaft rod two.

[0007] Furthermore, both ends of the L-shaped block are rotatably connected to bevel gears that mesh with each other via a rotating shaft. The rotating shaft is rotatably connected to a mounting bracket at a corresponding position. The mounting bracket has a hexagonal groove in the middle that slides and engages with the hexagonal shaft.

[0008] Furthermore, the limiting telescopic component includes a sleeve one that is inserted and fixed to the base plate, a sleeve one that is slidably engaged at the top of the sleeve one, a sleeve two that is slidably engaged at the top of the sleeve one, a slide rod that is slidably engaged at the top of the sleeve two, and the top end of the slide rod is rotatably connected to a hexagonal shaft at a corresponding position.

[0009] Furthermore, the protective mechanism includes a support base fixedly connected to the L-shaped block, a rotating seat rotatably connected to the top of the support base, a baffle fixed to the top of the rotating seat, a rubber sleeve fitted and fixed to one end edge of the baffle, and a torsion spring provided between the rotating seat and the support base.

[0010] Furthermore, a bevel gear is fixed to the top of the shaft, and a connecting shaft that is rotatably connected to the support cylinder is fixed to one end of the hexagonal shaft. A bevel gear is fixed to one end of the two connecting shafts that passes through the support cylinder, and the bevel gear meshes with the bevel gear.

[0011] Furthermore, the outer side of the first shaft is provided with a sliding groove, and the inner side of the second shaft is provided with a circular hole for the first shaft to be inserted into for transmission. A slider that is slidably engaged with the sliding groove is fixed inside the circular hole.

[0012] Furthermore, the bottom surface of the drive housing is fixedly connected to the vehicle, a motor is fixed inside the drive housing, a drive gear is fixed at the output end of the motor, and a driven gear that meshes with the drive gear is fixed at the bottom of the external threaded tube.

[0013] Furthermore, a reducer is fixed inside the drive housing, an input gear that meshes with the driven gear is fixed at the input end of the reducer, an output gear is fixed at the output end of the reducer, and a driven gear that meshes with the output gear is fixed at the bottom end of the shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Multiple hexagonal shafts are rotatably connected in a ring at equal angles on the outside of the support cylinder. Each hexagonal shaft has a mounting bracket slidably fitted on its outside. The ends of two adjacent mounting brackets are rotatably connected by L-shaped blocks. The shaft drives a bevel gear to rotate, causing two oppositely arranged bevel gears to rotate synchronously in opposite directions. This causes the two oppositely arranged hexagonal shafts to rotate synchronously in opposite directions. The rotation of the hexagonal shafts causes the mounting brackets to rotate. Because the ends of adjacent mounting brackets are constrained by L-shaped blocks, the mounting brackets move along the hexagonal shaft towards the support cylinder during rotation. When the multiple mounting brackets rotate 90 degrees, the antenna boxes of multiple communication base stations are transformed from a horizontal storage state to a vertical installation state perpendicular to the ground. Conversely, the shaft rotates in the opposite direction, causing the multiple mounting brackets with antenna boxes to slide in the opposite direction along the hexagonal shaft and rotate to a square position, thus achieving automatic storage or unfolding of the communication base stations for use.

[0016] 2. The motor drives the drive gear to rotate, which in turn drives the driven paper wheel to rotate the external threaded tube. This causes the internal threaded tube, which is screwed into the external threaded tube, to move upward along the base plate. The internal threaded tube, along with the support cylinder, moves upward synchronously, allowing the antenna boxes on the multiple mounting brackets on the outside of the support cylinder to move upward away from the roof. Conversely, the motor drives the drive gear to rotate in the opposite direction, causing the external threaded tube to screw into the internal threaded tube in the opposite direction. This causes the internal threaded tube to move downward along with the multiple antenna boxes on the support cylinder. This allows the communication base station to be automatically adjusted to a high position on the roof for network coverage. It also makes it easier to adjust the position of the communication base station on the roof, reducing the height of the communication base station while accommodating its storage.

[0017] 3. The motor drives the drive gear to rotate, which in turn drives the driven gear one to rotate the external threaded tube, thus moving the support cylinder and multiple antenna boxes upwards as a whole. At the same time, the driven gear one meshes with the input end of the reducer, which reduces the rotation speed and makes the shaft two rotate synchronously at a speed lower than that of the external threaded tube. The rotation of shaft two causes shaft one to rotate with the hexagonal shaft, which unfolds the antenna boxes on the mounting brackets for standby. The upward movement of the support cylinder and the antenna boxes on the mounting brackets and the unfolding of the antenna boxes for standby are carried out simultaneously, which helps to improve the efficiency of automatic control and installation of communication base stations and reduce manpower input.

[0018] 4. Two L-shaped blocks are rotatably connected to baffles. As the mounting frame moves the L-shaped blocks up to the top of the support cylinder, the rubber sleeves on the edges of the two baffles abut against each other, allowing the two baffles to rotate into the shape of a roof ridge, shielding multiple antenna boxes under the baffles and protecting the antenna boxes and other communication base station equipment.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1-9In this embodiment of the invention, a mobile communication base station for emergency communication includes a base plate 100 embedded and fixed to the top of a vehicle. An internally threaded tube 110 is slidably inserted into the top of the base plate 100. A support cylinder 200 is fixed to the top of the internally threaded tube 110. Multiple hexagonal shafts 210 are rotatably connected to the outer side of the support cylinder 200 at equal angles. A shaft 220, meshing with two of the hexagonal shafts 210, is rotatably connected to the middle of the support cylinder 200. A mounting bracket 300 is slidably sleeved on the outer side of the hexagonal shafts 210. An antenna box 310 and an RRU are mounted and fixed on the outer side of the mounting bracket 300. The antenna box 310 and the RRU are connected via a feed line. Then, an L-shaped block 320 is rotatably connected between the ends of two adjacent mounting brackets 300. A protective mechanism 400 is fixed on the top of the two L-shaped blocks 320. Two limiting telescopic members 500 are fixed on the top surface of the base plate 100. The top of the limiting telescopic member 500 is rotatably connected to the corresponding hexagonal shaft 210. An external threaded tube 111 is screwed into the internal threaded tube 110. A shaft 221 that is rotatably inserted into the internal threaded tube 110 and slidably engaged with shaft 220 is inserted into the internal threaded tube 110. A drive housing 600 for driving the external threaded tube 111 and shaft 221 to rotate is provided at the bottom of the external threaded tube 111 and shaft 221.

[0031] Specifically, the motor 610 drives the external threaded tube 111 to rotate, causing the support cylinder 200 to move upwards along with the antenna boxes 310 of multiple communication base stations. Simultaneously, the external threaded tube 111 drives the hexagonal shaft 210 to rotate at low speed via the reducer 620. The rotation of the hexagonal shaft 210 causes the mounting bracket 300 to rotate. Because the ends of adjacent mounting brackets 300 are constrained by the rotation of the L-shaped block 320, the mounting brackets 300 move along the hexagonal shaft 210 toward the support cylinder 200 during rotation. When the multiple mounting brackets 300 rotate 90 degrees, the antenna boxes 310 of multiple communication base stations are transformed from a horizontal storage state to a vertical installation state perpendicular to the ground. During this process, the external threaded tube 111 drives the antenna boxes 310 on the multiple mounting brackets 300 to move upwards to the top of the vehicle via the support cylinder 200, realizing automatic height adjustment and deployment of the antenna boxes 310 to cover the network for standby.

[0032] like Figure 4 As shown, in this embodiment, both ends of the L-shaped block 320 are rotatably connected to bevel gears 321 that mesh with each other via a rotating shaft. The rotating shaft is rotatably connected to the mounting bracket 300 at the corresponding position. The mounting bracket 300 has a hexagonal groove in the middle that slides and engages with the hexagonal shaft 210.

[0033] In this embodiment, during the sliding and rotation of the mounting bracket 300 along the hexagonal shaft 210, two adjacent bevel gears 321 mesh and rotate, so that the ends of the two adjacent mounting brackets 300 are in an active state. The cross-section of the hexagonal shaft 210 is hexagonal, which facilitates rotation and drives the mounting bracket 300 to rotate, thereby achieving the effect of adjusting the position of the mounting bracket 300.

[0034] like Figure 2 As shown, in this embodiment, the limiting telescopic member 500 includes a sleeve 1 that is inserted and fixed to the base plate 100. The top of the sleeve 1 is slidably engaged with a tube 1, the top of the tube 1 is slidably engaged with a tube 2, the top of the tube 2 is slidably engaged with a slide rod, and the top of the slide rod is rotatably connected to a hexagonal shaft 210 at a corresponding position.

[0035] In this embodiment, the limiting telescopic member 500 is similar to the multi-stage telescopic rod in the prior art. It is mainly used in conjunction with the rotation of the external threaded tube 111 to prevent the hexagonal shaft 210 from revolving around the support cylinder 200. This allows the external threaded tube 111 to rotate, causing the support cylinder 200 to move upward with multiple hexagonal shafts 210. During the upward movement, the length of the limiting telescopic member 500 increases.

[0036] like Figure 9 As shown, in this embodiment, a bevel gear 230 is fixed to the top of the shaft 220, and a connecting shaft that is rotatably connected to the support cylinder 200 is fixed to one end of the hexagonal shaft 210. A bevel gear 240 is fixed to one end of the two connecting shafts that passes through the support cylinder 200. The bevel gear 240 meshes with the bevel gear 230 for transmission.

[0037] In this embodiment, the connecting shaft enables the hexagonal shaft 210 to rotate stably on the support cylinder 200, and the bevel gear 1 230 and bevel gear 240 mesh and drive each other, so that the two hexagonal shafts 210 arranged opposite to each other can rotate synchronously in opposite directions, thereby realizing the unfolding and storage of multiple mounting brackets 300.

[0038] like Figure 7 As shown, in this embodiment, a sliding groove 222 is provided on the outer side of shaft 1 220, and a circular hole is provided inside shaft 221 for shaft 1 220 to be inserted for transmission. A slider is fixed inside the circular hole and is slidably engaged with the sliding groove 222. The slider slides inside the sliding groove 222 to satisfy the requirement that shaft 1 220 can slide inside shaft 221 for height adjustment, and can also rotate synchronously with shaft 221.

[0039] like Figure 6As shown, in this embodiment, the bottom surface of the drive housing 600 is fixedly connected to the vehicle. A motor 610 is fixed inside the drive housing 600. A drive gear 611 is fixed to the output end of the motor 610. A driven gear 1111 that meshes with the drive gear 611 is fixed to the bottom of the external threaded tube 111. A reducer 620 is fixed inside the drive housing 600. An input gear 621 that meshes with the driven gear 1111 is fixed to the input end of the reducer 620. An output gear 622 is fixed to the output end of the reducer 620. A driven gear 2211 that meshes with the output gear 622 is fixed to the bottom end of the shaft 221.

[0040] In this embodiment, the motor 610 drives the drive gear 611 to rotate, which in turn drives the driven gear 1111 to rotate the external threaded tube 111, thus moving the support cylinder 200 and multiple antenna boxes 310 upwards as a whole. At the same time, the driven gear 1111 engages with the input end of the reducer 620, which reduces the rotation speed and causes the shaft 221 to rotate synchronously at a speed lower than that of the external threaded tube 111. The rotation of the shaft 221 causes the shaft 220 to rotate the hexagonal shaft 210, thus unfolding the antenna boxes 310 on the multiple mounting brackets 300 for standby. The upward movement of the support cylinder 200 and the unfolding of the antenna boxes 310 on the mounting brackets 300 are carried out simultaneously, which helps to improve the efficiency of automatic control installation of communication base stations and reduce manpower input.

[0041] In practice, initially, the internal threaded tube 110 is fully sleeved on the outside of the external threaded tube 111, shaft 1 220 is inserted into shaft 221, the limiting telescopic component 500 is in a retracted state, and multiple mounting brackets 300 with antenna boxes 310 are mounted on the vehicle roof. At this time, the communication base station does not occupy a large space. When the base station needs to be used, or when the communication base station needs to be used after passing through a height-restricted road section, the motor 610 drives the drive gear 611 to rotate, causing the external threaded tube 111 to rotate and engage with it. The internally threaded tube 110 moves upward along with the support cylinder 200. The support cylinder 200 moves upward along with the mounting brackets 300 on the outer side of multiple hexagonal shafts 210. The mounting brackets 300 move upward along with multiple antenna boxes 310. Simultaneously, the externally threaded tube 111 rotates the shaft 221 at low speed via the reducer 620. The shaft 221 rotates the shaft 220, causing the bevel gear 230 to rotate the bevel gears 240 on the two hexagonal shafts 210. This, in turn, causes the hexagonal shafts 210 to rotate, carrying the mounting brackets 300. (Refer to the instruction manual.) Figure 4The arrow indicates the direction in which the mounting bracket 300 rotates and unfolds. Multiple mounting brackets 300 slide and rotate along the hexagonal axis 210 toward the support cylinder 200. The mounting bracket 300 rotates 90 degrees to make the antenna box 310 vertically installed for standby. At the same time, the internal threaded tube 110 moves the support cylinder 200 upward to the roof of the vehicle, so that the unfolded antenna box 310 can be raised for use.

[0042] Example 2

[0043] Based on Example 1, in order to prevent external factors such as hail from damaging the base station and to protect communication base station equipment such as antenna box 310.

[0044] like Figure 5 As shown, in this embodiment, the protective mechanism 400 includes a support base 410 fixedly connected to the L-shaped block 320. A rotating base 420 is rotatably connected to the top of the support base 410. A baffle 430 is fixed to the top of the rotating base 420. A rubber sleeve is fitted and fixed to one end edge of the baffle 430. A torsion spring is provided between the rotating base 420 and the support base 410.

[0045] Specifically, in the initial state, the baffle 430 is placed squarely on the L-shaped block 320, without occupying any height space. During the unfolding process of the mounting bracket 300 with the antenna box 310, the L-shaped block 320 moves the baffle 430 above the antenna box 310. The two baffles 430 work together to block the space above the antenna box 310, preventing damage to the antenna box 310 from external factors such as hail. A torsion spring is sleeved on the shaft between the rotating seat 420 and the support seat 410. When the baffle 430 is tilted, the torsion spring is in a torsion state. When the mounting bracket 300 is folded into square, the two baffles 430 lose their mutual abutment and will rotate to the square folded state under the elastic force of the torsion spring.

[0046] In this invention, the antenna box 310 on the communication base station is connected to the RRU via a feeder, which is existing technology. The working principle of the specific communication base station will not be described in detail.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
