When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] In one embodiment, see Figures 1 to 3 As shown, the utility model provides a sealed cabin for reliability testing of a communication vehicle, comprising a cabin body 1, a mounting seat 2, a rotating platform 3, a driven gear ring 4, a driving motor 5 and a driving gear 6.

[0024] The cabin 1 has a test cavity 101, and a through installation slot 102 is provided at the bottom of the test cavity 101. The cabin 1 adopts a sealed design, and an openable and closable sealed door is provided at one end of the cabin 1; test items related to reliability testing, such as noise test, sealing test, etc., can be installed at different positions in the test cavity 101.

[0025] The mounting base 2 is fixed to the bottom of the cabin 1 by bolts.

[0026] The rotating platform 3 is arranged in the installation slot 102 and connected to the mounting seat 2 by means of rotation. The bottom of the test cavity 101 is flush with the upper end surface of the rotating platform 3, and the communication vehicle is fixed to the upper end of the rotating platform 3.

[0027] The driven gear ring 4 is fixedly connected to the rotating platform 3 by bolts.

[0028] The driving motor 5 is fixedly connected to the mounting base 2 by bolts.

[0029] The driving gear 6 is fixed to the output shaft of the driving motor 5 by a key connection, and meshes with the driven gear ring 4. When the driving motor 5 is working, the output shaft of the driving motor 5 drives the driving gear 6 to rotate, the driving gear 6 drives the driven gear ring 4 to rotate, the driven gear ring 4 drives the rotating table 3 to rotate, and the rotating table 3 drives the communication vehicle to rotate, so that the communication vehicle rotates to a suitable working position.

[0030] Specifically, the utility model drives the communication vehicle to rotate through the rotating table 3, so that the communication vehicle can be rotated to a set working angle, and cooperates with the test items of different workstations, thereby realizing multiple tests on the communication vehicle in one field, reducing the cost of reliability testing of the communication vehicle, and the rotating table 3 and related structures are arranged outside the cabin 1, which is convenient for the installation of reliability testing equipment and the disassembly, assembly and maintenance of the sealed cabin for reliability testing of the communication vehicle.

[0031] As an example, see Figures 1 to 3 As shown, a support frame 7 is fixed to the bottom of the cabin body 1 by bolts.

[0032] Specifically, in this example, the bottom space of the cabin body 1 is increased by the support frame 7, which facilitates the disassembly and assembly of other structures and improves the maintenance efficiency of the sealed cabin.

[0033] As an example, see Figures 1 to 5 As shown, a mounting groove 201 is formed at the upper end of the mounting seat 2 , and the driven gear ring 4 and the driving gear 6 are both disposed in the mounting groove 201 .

[0034] Specifically, this example arranges the driven gear ring 4 and the driving gear 6 in the installation groove 201, thereby reducing the exposure of the rotating structure to the air, reducing the pollution to the driven gear ring 4 and the driving gear 6, and increasing the service life of the sealed cabin.

[0035] As an example, see Figures 1 to 5 As shown, a plurality of auxiliary wheels 8 are fixed in the installation groove 201 by bolts, and a limiting ring 9 is fixed at the bottom of the rotating platform 3 by bolts, and the auxiliary wheels 8 are in conflict with the outer wall of the limiting ring 9.

[0037] As an example, see Figures 1 to 5 As shown, the auxiliary wheel 8 includes an auxiliary seat 81 , which is fixedly connected to the mounting groove 201 by bolts, an auxiliary shaft 82 is mounted on the auxiliary seat 81 by a bearing connection, and a wheel body 83 is fixed on the outer wall of the auxiliary shaft 82 .

[0038] Specifically, in this example, the rotation of the limiting ring 9 is limited by the wheel body 83, thereby ensuring the stability of the limiting ring 9 during rotation.

[0039] As an example, see Figures 1 to 5 As shown, a first flange 831 and a second flange 832 are provided on the outer wall of the wheel body 83 , the upper end of the first flange 831 abuts against the bottom of the limiting ring 9 , and the second flange 832 abuts against the outer wall of the limiting ring 9 .

[0040] Specifically, in this example, the second flange 832 cooperates with the limiting ring 9 to limit the movement of the rotating platform 3 in the horizontal direction, thereby ensuring the stability of the sealed cabin during operation.

[0041] As an example, see Figures 1 to 5 As shown, a plurality of supporting wheels 10 are fixed to the bottom of the rotating platform 3 , and the outer walls of the supporting wheels 10 are in contact with the bottom of the mounting groove 201 .

[0042] Specifically, in this example, the rotating table 3 is supported by the cooperation between the supporting wheel 10 and the mounting groove 201, so that it can withstand a large load and ensure the service life of the sealed cabin.

[0043] As an example, see Figures 1 to 5 As shown, a plurality of positioning grooves 31 for positioning the communication vehicle are provided at the upper end of the rotating platform 3 .

[0044] Specifically, in this example, the positioning groove 31 is used to limit the movement of the communication vehicle, thereby ensuring the stability of the communication vehicle during rotation and preventing the communication vehicle from deflecting.

[0045] In general, the utility model drives the communication vehicle to rotate through the rotating platform 3, so that the communication vehicle can rotate to the set working angle, realizes the detection of the communication vehicle at different workstations, and the rotating platform 3 and related structures are arranged outside the cabin 1, which is convenient for the installation of reliability testing equipment and the disassembly and maintenance of the sealed cabin for reliability testing of the communication vehicle. At the same time, through the cooperation of the auxiliary wheel 8 and the limit ring 9, the horizontal movement of the rotating platform 3 is limited, and it has a high bearing capacity, which can meet the load requirements of the communication vehicle and improve the service life of the sealed cabin.
