Description

Technical Field

[0001] The utility model relates to the field of mobile communication devices, and particularly to a double-sided sliding cover mechanism. Background Art

[0002] With the development of mobile communication technology, mobile communication devices in the form of mobile cabins have been widely used. In these devices, the protection and operation of antennas are crucial. At present, there are various forms of sliding covers arranged on the top of the mobile cabin, mainly including electric awning rod type, flip cover type, lift cover type, sliding cover type, etc. These sliding cover mechanisms usually use a reduction motor as the power source.

[0003] However, the prior art has the following problems: Although the electric awning rod type sliding cover provides a wide field of view for the antenna, its matching with the rigid mobile cabin is not good, and it still occupies a certain space after being compressed. After the lift cover type and flip cover type sliding covers are opened, the cabin cover will extend beyond the left and right sides of the mobile cabin by a large size and cannot bear personnel to work on it; while the single-sided sliding type sliding cover requires no obstruction in the sliding direction, and support is needed under the sliding cover after sliding. Therefore, the existing electric sliding covers are difficult to meet the requirements of the lifting and working of the antenna (length 2000mm × width 1300mm × height 1730mm) in a 2-meter cabin (dimensions: length 2000mm × width 2348mm × height 2100mm) under the conditions of small space at the top of the mobile cabin and obstruction in the front and back. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: to solve the above-mentioned existing technical problems, and provide a double-sided sliding cover mechanism to achieve the advantages of a large sliding cover in a small space, short opening time, and small obstruction to the work on the top of the mobile cabin.

[0009] Wherein, the transmission system is connected to the driving device for transmitting power and driving the guiding system to drive the left sliding cover and the right sliding cover to move synchronously;

[0010] The guiding system includes a first three - section guide rail and a second three - section guide rail. The first three - section guide rail and the second three - section guide rail are respectively installed at the bottom of the left and right sliding covers, extending along the length direction of the sliding cover, one end of which is fixed at the edge of the top of the mobile cabin, and the other end is connected to the bottom of the corresponding sliding cover.

[0011] Further, the driving device is a double-headed servo motor; the transmission system includes a front coupling, a rear coupling, a front connecting rod, a rear connecting rod, a front commutator, a rear commutator, a front lead screw, a rear lead screw, a front lead screw nut, and a rear lead screw nut.

[0012] Further, the double-headed servo motor is installed at the center position on the top of the shelter, and the output shafts at both ends are respectively connected to the front connecting rod and the rear connecting rod through the front coupling and the rear coupling;

[0013] The front connecting rod is connected to the front lead screw through the front commutator, and the rear connecting rod is connected to the rear lead screw through the rear commutator;

[0014] The front lead screw and the rear lead screw are installed along the length direction of the sliding cover, and both ends are respectively connected to the bottoms of the left and right sliding covers;

[0015] The front lead screw nut is installed on the front lead screw and fixedly connected to the left sliding cover, and the rear lead screw nut is installed on the rear lead screw and fixedly connected to the right sliding cover;

[0016] The first three sections of guide rails and the last three sections of guide rails are respectively installed at the bottoms of the left and right sliding covers, extending along the length direction of the sliding cover, with one end fixed at the edge of the top of the shelter and the other end connected to the bottom of the corresponding sliding cover.

[0017] Further, it also includes a manual operating system, and the manual operating system includes: a hand crank;

[0018] a front precision planetary reducer and a rear precision planetary reducer;

[0019] Wherein, the hand crank is connected to the transmission system through the front precision planetary reducer and the rear precision planetary reducer, and the position of the sliding cover is precisely adjusted by rotating the hand crank.

[0020] Further, it also includes a limiting device, and the limiting device is set at the position when the sliding cover is fully unfolded, used to ensure that both side sliding covers can bear a predetermined weight.

[0021] Further, a rainproof device is provided at the joint of the left sliding cover and the right sliding cover, and the rainproof device includes a rain eaves, a rain eaves support plate, and a rainproof rubber strip.

[0022] The beneficial effects of the present utility model are as follows:

[0023] By adopting a double-sided sliding cover mechanism, including left and right sliding covers and a sliding cover mechanism, wherein the transmission system is connected to a driving device for transmitting power and driving the left and right sliding covers to move synchronously, the effective opening and closing of the sliding cover are realized under the conditions of limited space at the top of the shelter and blockages at the front and rear.

[0030] The following further illustrates the present utility model in conjunction with the drawings and embodiments, but these specific implementation schemes do not limit the protection scope of the present utility model in any way.

[0031] Embodiment 1

[0032] As Figures 1-4 shown, a double-sided sliding cover mechanism 2 includes a sliding cover 1 and a sliding cover mechanism 2 installed on the top of the shelter 20.

[0033] In this embodiment, the sliding cover 1 is composed of a left sliding cover 1-1 and a right sliding cover 1-2, and each sliding cover 1 is composed of four wall plates to form a "C" - shaped frame. A rainproof device 3 is arranged at the docking position of the left sliding cover 1-1 and the right sliding cover 1-2, including a rain eaves 31, a rain eaves support plate 32 and a rainproof rubber strip 33. The rainproof device 3 can effectively defend against the rain outside the hatch cover and protect the internal equipment.

[0034] In this embodiment, the sliding cover mechanism 2 includes a double-headed servo motor 4, a front coupling 5, a rear coupling 6, a front connecting rod 7, a rear connecting rod 8, a front commutator 9, a rear commutator 10, a front three - section guide rail 11, a rear three - section guide rail 12, a front lead screw 13, a rear lead screw 14, a front lead screw nut 15, a rear lead screw nut 16, a front precision planetary reducer 17, a rear precision planetary reducer 18, a hand crank 19, as well as auxiliary installation connectors and a rainproof device 3.

[0035] At the bottom of the left sliding cover 1-1 and the right sliding cover 1-2, the front three - section guide rail 11 and the rear three - section guide rail 12 are respectively installed along the length direction of the sliding cover 1. One end of these guide rails 11, 12 is fixed to the edge of the top of the shelter 20, and the other end is connected to the bottom of the sliding cover 1. The function of the guide rails is to guide the sliding cover 1 to move along a specific trajectory and provide stable support for the sliding cover 1.

[0036] The double-headed servo motor 4 is installed at the central position of the top of the shelter 20, and the output shafts at both ends are respectively connected to the front connecting rod 7 and the rear connecting rod 8 through the front coupling 5 and the rear coupling 6. The front connecting rod 7 and the rear connecting rod 8 are respectively connected to the front lead screw 13 and the rear lead screw 14 through the front commutator 9 and the rear commutator 10. This transmission chain design ensures the smooth transmission of power and the synchronous movement of the left and right sliding covers.

[0037] The front lead screw 13 and the rear lead screw 14 are installed along the length direction of the sliding cover 1, and both ends are respectively connected to the bottom of the left sliding cover 1-1 and the right sliding cover 1-2. The front lead screw nut 15 and the rear lead screw nut 16 are respectively installed on the front lead screw 13 and the rear lead screw 14 and are fixedly connected to the corresponding sliding cover 1. When the front lead screw 13 and the rear lead screw 14 rotate, the front lead screw nut 15 and the rear lead screw nut 16 will move along the front lead screw 13 and the rear lead screw 14, thereby driving the sliding cover 1 to open or close.

[0038] For easy manual operation, a hand crank 19 is installed at an appropriate position of the sliding cover mechanism 2. The hand crank 19 is connected to the transmission system through a front precision planetary reducer 17 and a rear precision planetary reducer 18. This design greatly reduces the force required for manual operation while ensuring the accuracy of the operation. When manual control of the sliding cover 1 is required, the operator can precisely adjust the position of the sliding cover 1 by rotating the hand crank 19. In this embodiment, the auxiliary installation connectors include bolts and nuts, brackets, connecting plates, gaskets and washers, snaps or quick connectors, etc., which are used to fix various components. Although these auxiliary installation connectors are small in size, they are crucial for the stability and reliability of the entire mechanism. Since they are conventional technologies, no attached drawings are provided for elaboration here.

[0039] In addition, to ensure the stability of the sliding cover 1 when it is fully extended, a limiting device (not shown in the figure) is provided at the fully extended position (1035 mm) of the sliding cover 1. The limiting device is usually a mechanical stop block, which can ensure that both the left sliding cover 1-1 and the right sliding cover 1-2 on both sides can bear a weight of 150 kg.

[0040] The working principle and method of the bilateral synchronous sliding cover mechanism described in the above embodiment are as follows:

[0041] The first step: Startup preparation. The operator first checks whether the system is in a normal state and selects the electric or manual operation mode.

[0042] The second step: Opening the sliding cover 1. If the electric mode is selected, start the double-headed servo motor 4; if the manual mode is selected, use the hand crank 19. In the electric mode, the motor 4 drives the front connecting rod 7 and the rear connecting rod 8 to rotate through the front coupling 5 and the rear coupling 6. The front connecting rod 7 and the rear connecting rod 8 drive the front lead screw 13 and the rear lead screw 14 to rotate through the commutators 9, 10. The front lead screw 13 and the rear lead screw 14 drive the front lead screw nut 15 and the rear lead screw nut 16 to move, thereby pushing the sliding cover 1 to open. In the manual mode, the torque is increased through the hand crank 19, the front precision planetary reducer 17 and the precision planetary reducer 18, driving the front lead screw 13 and the rear lead screw 14 to rotate, and realizing the same opening process.

[0043] The third step: When the sliding cover 1 is fully opened in place (1035 mm), the limiting device automatically locks to ensure the stability of the sliding cover 1. At this time, both sliding covers on both sides can bear a weight of 150 kg.

[0044] The fourth step: After the sliding cover 1 is fully opened, the operator can perform operations and maintenance on the antenna on the sliding cover 1.

[0045] The fifth step: After the work is completed, the operator closes the sliding cover 1 in the reverse order of opening. In the electric mode, the double-headed servo motor 4 runs in reverse; in the manual mode, rotate the hand crank 19 in reverse.

[0046] Finally, after the closing process is completed, check whether the sliding cover 1 is completely closed to ensure that the rainproof device 3 is in place.

[0047] The above are only the preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model. Any innovative improvement or replacement based on the present utility model shall fall within the scope of the claims of the present utility model. At the same time, the various parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of the present utility model, those of ordinary skill in the art can make various alternative selections, and these alternative solutions should also be regarded as falling within the protection scope of the present utility model.
