DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: This embodiment is intended to help solve the problem that in areas with weak signals or remote areas, fixed-angle antennas may not be able to obtain sufficient signal strength, thereby limiting the communication coverage. Figure 1 - Figure 4 The vehicle communication antenna includes a vehicle body 100 and an antenna body 400.

[0024] A mounting plate 110 is installed on the top of the vehicle body 100, a support frame 410 is installed on the mounting plate 110, a fixing sleeve 420 is installed on the support frame 410, the antenna body 400 is installed in the fixing sleeve 420, a fixing block 200 is installed on the mounting plate 110, an adjusting block 300 is installed on the bottom of the support frame 410, the adjusting block 300 is arranged on the upper side of the fixing block 200, an adjusting half wheel 210 is installed on the fixing block 200, a groove 310 is opened in the adjusting block 300, an adjusting rod 320 is arranged in the groove 310, and the adjusting rod 320 is located on the upper side of the adjusting half wheel 210.

[0025] An adjusting gear 321 is disposed outside the adjusting half wheel 210, and a threaded ring 211 is disposed outside the adjusting rod 320, and the threaded ring 211 is meshed with the adjusting gear 321. When the antenna angle needs to be adjusted, the adjusting rod 320 is manually operated to move it in the groove 310. When the adjusting rod 320 moves, the connection between the adjusting rod 320 and the adjusting half wheel 210 allows the adjusting half wheel 210 to rotate following the movement of the adjusting rod 320. By rotating the adjusting half wheel 210, the angle of the antenna is also adjusted accordingly.

[0026] The adjustment of the antenna angle is achieved through the linkage of the adjustment rod 320, the adjustment half wheel 210 and the groove 310. By manually operating the adjustment rod 320, the user can flexibly adjust the angle of the antenna to obtain a better signal reception or transmission effect.

[0027] A control rod 340 is installed at the end of the adjustment rod 320, a through hole 330 is opened in the adjustment block 300, and the control rod 340 is plugged into the through hole 330. A control button 350 is installed at the end of the control rod 340. When the angle of the antenna body 400 needs to be adjusted, the control button 350 only needs to be turned, and the control rod 340 will drive the adjustment block 300 to adjust according to the angle of the adjustment half wheel 210, thereby changing the angle of the antenna. An anti-skid pattern 351 is arranged on the outside of the control button 350. The anti-skid pattern 351 can prevent the finger from sliding or sliding unsteadily, ensuring the accuracy and safety of the operation. The fixed block 200 is set in a semicircular shape, the bottom of the fixed block 200 is fitted with the mounting plate 110, and the inner radius of the adjustment half wheel 210 corresponds to the radius of the fixed block 200. A mounting groove 212 is opened at the bottom of the adjustment half wheel 210, and a mounting rod 111 corresponding to the mounting groove 212 is installed on the mounting plate 110, and the mounting rod 111 is plugged into the mounting groove 212.

[0028] Limiting plates 220 are installed on both sides of the fixed block 200. The limiting plates 220 are set as semicircular plates. Limiting rings 230 are installed on the sides of the limiting plates 220. The limiting rings 230 are fixedly installed with the limiting plates 220. A mounting block 360 is installed at the bottom of the adjustment block 300. A fitting groove 361 is opened in the mounting block 360. The surfaces of the limiting plate 220 and the limiting ring 230 fit in the fitting groove 361.

[0029] The limiting ring 230 is fixed on the limiting plate 220, further strengthening the connection between the limiting plate 220 and the adjusting block 300. The fitting of the mounting block 360 in the fitting groove 361 with the surfaces of the limiting plate 220 and the limiting ring 230 provides a stable movement limit, ensuring that the adjusting block 300 moves within a specified range.

[0030] In this embodiment: a fixed block 200 is installed on the mounting plate 110, an adjusting block 300 is installed at the bottom of the support frame 410, the adjusting block 300 is arranged on the upper side of the fixed block 200, an adjusting half wheel 210 is installed on the fixed block 200, a groove 310 is opened in the adjusting block 300, an adjusting rod 320 is arranged in the groove 310, and the adjusting rod 320 is located on the upper side of the adjusting half wheel 210. When it is necessary to adjust the angle of the antenna body 400, only the control button 350 needs to be rotated to accurately adjust the angle of the antenna to obtain a better signal reception or transmission effect. The threaded ring 211 is engaged with the adjusting gear 321 on the adjusting half wheel 210, so that the rotation of the adjusting rod 320 can directly affect the angle change of the antenna, providing more precise adjustment control.

[0031] Embodiment 2: This embodiment is intended to promote the solution of the problem of further strengthening the stability of the device. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1 - Figure 4 .

[0032] The limiting ring 230 has an annular groove 231, and a screw rod 362 is installed at the bottom of the mounting plate 110. The screw rod 362 is inserted into the annular groove 231, and a fixing nut 363 is installed at the end of the screw rod 362. By rotating the screw rod 362, the movement of the screw rod inserted into the annular groove 231 will cause the limiting ring 230 to move. Due to the presence of the fixing nut 363, the screw rod 362 can be kept at the selected position to achieve the required angle adjustment.

[0033] A buffer spring 232 is installed in the annular groove 231, one end of the buffer spring 232 is in contact with the inner wall of the annular groove 231, and the other end of the buffer spring 232 is in contact with the screw rod 362. The elasticity of the buffer spring 232 can reduce the impact and vibration of components such as the screw rod 362 and the adjustment block 300, thereby avoiding the problem of device stability caused by external interference.

[0034] In this embodiment: by inserting the screw 362 and installing the fixing nut 363, the structural stability of the device can be maintained. At the same time, the linear movement of the screw 362 and the fixing effect of the fixing nut 363 can ensure reliable and precise adjustment of the position of the adjustment half wheel 210 and the antenna within the selected angle range.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
