[0033] Please refer to Figures 1 to 4 The embodiment of the utility model provides a kind of anti-vibration antenna, which comprises: shell 1 and at least one group of anti-vibration components 3 and antenna body 2 arranged in shell 1.

[0034] Wherein, anti-vibration component 3 includes fixing piece 31, first elastic piece 32 and second elastic piece 33.The one end of fixing piece 31 has abutting portion 311, and the other end of fixing piece 31 is fixedly connected with shell 1 after vertically penetrating antenna body 2, first elastic piece 32 and second elastic piece 33 are all sleeved on fixing piece 31, and first elastic piece 32 and second elastic piece 33 are separated on the both sides of antenna body 2, and the both ends of first elastic piece 32 are respectively abutted against abutting portion 311 and antenna body 2, and the both ends of second elastic piece 33 are respectively abutted against antenna body 2 and shell 1.

[0035] It can be understood that in the embodiment, based on the vertical penetration of fixing piece 31 through antenna body 2, the antenna body 2 is limited to only move vertically.When external vibration force in other directions is applied, due to the radial limiting action of fixing piece 31, the antenna body 2 cannot be displaced horizontally or deflected, thereby maintaining the basic stability at the structural level and effectively suppressing the direct impact of non-vertical vibration on the antenna body 2.Due to the fact that first elastic piece 32 and second elastic piece 33 are also sleeved on fixing piece 31, and first elastic piece 32 and second elastic piece 33 are arranged on the upper and lower sides of the vertical direction of antenna body 2, when vertical vibration causes displacement of antenna body 2, it will interact with the elastic element, i.e., compressing the first elastic piece 32 above when vibrating upward, and extruding the second elastic piece 33 below when vibrating downward.Through the elastic deformation of the elastic element to absorb vibration energy, mechanical vibration is converted into elastic potential energy, and then energy is released through the elastic recovery process to form dynamic balance of vibration buffering.In this way, through the design of the elastic element, the antenna body 2 maintains a reasonable dynamic response range in the vertical direction, avoiding both rigid impact and excessive displacement, and finally achieving significant attenuation of vibration amplitude.Therefore, the embodiment of the application realizes the radial limiting of horizontal vibration and the axial elastic buffering of vertical vibration through the synergistic effect of mechanical limiting and elastic buffering.This multidimensional anti-vibration protection system enables the antenna to adapt to complex vibration environments and ensures the stability of its spatial position and the reliability of its electrical performance.

[0036] Optionally, the first elastic member 32 and the second elastic member 33 can each be Figure 2 The spring shown, the first elastic member 32 and the second elastic member 33 can each also be an elastic washer, including but not limited to a rubber washer, a silicone washer, etc., which is sleeved on the fixing member 31.

[0037] Exemplarily, as shown in Figure 2 and Figure 3 , the fixing member 31 can be in a "T" type structure similar to a screw, the abutting portion 311 of the fixing member 31, i.e. the horizontal portion at the top end of the "T" type structure, is the head of the screw. Preferably, the projection of the first elastic member 32 on the abutting portion 311 is located within the abutting portion 311, so as to be able to abut against the abutting portion 311 more stably.

[0038] In one specific embodiment, please refer to Figures 2 to 4 , the side wall of the antenna body 2 horizontally extends outward to form a ring-shaped outward extension 21, and a plurality of groups of anti-vibration assemblies 3 are arranged on the outward extension 21 at intervals along the circumferential direction thereof.

[0039] In the plurality of groups of anti-vibration assemblies 3, the fixing member 31 vertically penetrates the outward extension 21 to form a stable structural connection. The first elastic member 32 and the second elastic member 33 are arranged at intervals on both sides of the outward extension 21 to play a buffering and supporting role. Specifically, the two ends of the first elastic member 32 abut against the abutting portion 311 and the outward extension 21 respectively, and the two ends of the second elastic member 33 abut against the outward extension 21 and the shell 1 respectively. Thus, the antenna body 2 can realize the buffering and damping functions under the synergistic action of the plurality of groups of anti-vibration assemblies 3. The plurality of groups of anti-vibration assemblies 3 are arranged at intervals to provide uniform and sufficient buffering and limiting effects for the antenna body 2, thereby optimizing the damping effect. Moreover, since the anti-vibration assemblies 3 are arranged around the periphery of the antenna body 2, the anti-vibration assemblies 3 can preferentially absorb and buffer the vibrations from the outside, reducing the transmission of vibration energy to the middle part of the antenna body 2. In this way, the vibration impact on the components in the middle part of the antenna body 2 will also be correspondingly reduced, thereby reducing the risk of damage to these components. In addition, the arrangement of the plurality of groups of anti-vibration assemblies 3 enhances the working reliability of the antenna in complex environments. Even if one or several groups of anti-vibration assemblies 3 fail due to some reason, the other assemblies can still continue to function to maintain a certain anti-vibration capability. This redundant design ensures the stable operation of the antenna in harsh environments, improves the overall reliability and service life of the antenna.

[0040] Optionally, the anti-vibration assemblies 3 can be 2 groups, 3 groups, 4 groups or more, which are not specifically limited in the embodiment. Preferably, the plurality of groups of anti-vibration assemblies 3 are arranged at equal intervals along the circumferential direction of the outward extension 21, thereby providing uniform buffering and limiting effects for the antenna body 2.

[0041] Optionally, the outward extension 21 can be in a Figure 3The circular ring shape can also be a rectangular ring shape, an equilateral triangle ring shape, or other regular ring shapes. The specific shape of the extension portion 21 is affected by the antenna body 2, and the present embodiment does not make specific limitations thereto.

[0042] Further, please refer again to Figures 2 to 4 , the side of the extension portion 21 away from the first elastic member 32 can also be provided with a support partition plate 4, and the end of the second elastic member 33 away from the shell 1 abuts against the extension portion 21 through the support partition plate 4. It can be understood that, compared with directly abutting against the extension portion 21 through the second elastic member 33, the support partition plate 4 can provide a larger support area for the antenna body 2, so that the stability of the antenna body 2 is further improved, and the vibration resistance of the antenna is further improved.

[0043] Preferably, the support partition plate 4 is configured to have flexibility, for example, to adopt a rubber support partition plate or a silica gel support partition plate, so as to provide a certain buffering effect while providing support.

[0044] Exemplarily, as Figure 4 shown, the support partition plate 4 can have a ring structure matched with the extension portion 21, and the support partition plate 4 is penetrated and limited by the fixing member 31.

[0045] In one specific embodiment, please refer to Figure 2 , the middle position of the antenna body 2 is provided with the vibration resistance assembly 3, and the middle position is located at the geometric center of the extension portion 21. It should be noted that not all components in the vibration resistance assembly 3 are located at the geometric center of the extension portion 21, but when the vibration resistance assembly 3 is regarded as a whole, the vibration resistance assembly 3 as a whole is located at the geometric center of the extension portion 21.

[0046] It can be understood that, in the present embodiment, in addition to the buffering and damping effect provided for the antenna body 2 by the multiple groups of vibration resistance assemblies 3 on the extension portion 21, the buffering and damping effect can also be provided for the antenna body 2 by the vibration resistance assembly 3 located at the middle position of the antenna body 2. Since the middle position is located at the geometric center of the extension portion 21, the cooperative damping effect of the middle and the periphery is uniformly distributed, and the damping effect is further improved. Moreover, the vibration resistance assembly 3 at the periphery can preliminarily buffer the external vibration and weaken the vibration intensity, and the vibration resistance assembly 3 at the middle position can buffer the remaining vibration, constituting a double buffering mechanism, so as to ensure that the antenna body has good stability.

[0047] In one specific embodiment, please continue to refer to Figure 2 , the inside of the shell 1 is divided into a first region B and a second region C from top to bottom, the antenna body 2 is located in the first region B, and the bottom of the antenna body 2 is provided with a shielding cover 5. The boundary line between the first region B and the second region C can refer to the dashed line in the figure.

[0048] In practical applications, the housing 1 is further provided with a power module, a processor and other components. Since the power module, the processor and other components will cause electromagnetic interference to the antenna body 2, these components are preferably arranged in the second region C, so that these components can be kept at a certain distance from the antenna body 2 in space, thereby reducing the influence of electromagnetic interference on the antenna body 2. The shielding cover 5 is arranged at the bottom of the antenna body 2, which can block the electromagnetic interference generated by the components from propagating in the direction of the antenna body 2.

[0049] Optionally, the shielding cover 5 is not limited to being arranged at the bottom of the antenna body 2 by adhesion, insertion, buckle connection or the like.

[0050] In some cases, the shielding cover 5 is positioned and supported by at least one set of anti-vibration assemblies 3. Specifically, the shielding cover 5 is penetrated by the fixing member 31 of the at least one set of anti-vibration assemblies 3, and in the at least one set of anti-vibration assemblies 3, the end of the second elastic member 33 away from the housing 1 abuts against the bottom of the antenna body 2 through the shielding cover 5, so that the second elastic member 33 exerts a variable supporting force on the shielding cover 5 in the vertical direction. Thus, the horizontal position of the shielding cover 5 is limited by the fixing member 31, and the vertical position of the shielding cover 5 can change synchronously with the antenna body 2 under the action of the second elastic member 33. This synchronous change not only ensures the stability of the relative position relationship between the shielding cover 5 and the antenna body 2, but also enables the shielding cover 5 to always effectively cover the bottom of the antenna body 2, thereby providing continuous electromagnetic shielding protection for the antenna body 2.

[0051] Exemplarily, please refer to Figure 2 The shielding cover 5 can be penetrated by the fixing member 31 of the anti-vibration assembly 3 located at the middle position of the antenna body 2, and the shielding cover 5 is surrounded by the support partition 4.

[0052] Further, please refer to Figures 2 to 4 A gasket 6 can be arranged between the shielding cover 5 and the second elastic member 33, and a gasket 6 can also be arranged between the antenna body 2 and the first elastic member 32. The end of the second elastic member 33 away from the housing 1 abuts against the shielding cover 5 through the gasket 6, and the end of the first elastic member 32 away from the abutting portion 311 abuts against the antenna body 2 through the gasket 6.

[0053] It can be understood that the gasket 6 can further disperse and buffer external vibrations, thereby avoiding the impact force of the vibrations directly acting on the shielding cover 5 and the antenna body 2, so as to protect the shielding cover 5 and the antenna body 2. Moreover, the gasket 6 can also effectively limit the deviation or inclination of the first elastic member 32 and the second elastic member 33 during vibration, thereby ensuring the stability of the first elastic member 32 and the second elastic member 33 during vibration reduction.

[0054] In one specific embodiment, the inner wall of the shell 1 is provided with a boss 7, which is provided with a butt joint groove 71 corresponding to the fixing member 31, and the end of the fixing member 31 away from the abutting portion 311 is embedded in the butt joint groove 71, thereby achieving fixed connection with the shell 1.

[0055] Exemplarily, please refer to Figure 2 In the embodiment in which the interior of the shell 1 is divided into the first region B and the second region C, the boss 7 is located in the second region C, and the boss 7 protrudes towards the first region B, and the slot of the butt joint groove 71 is provided at the top end of the boss 7, and after the fixing member 31 is embedded in the butt joint groove 71, the antenna body 2 is positioned in the first region B by cooperation with the first elastic member 32 and the second elastic member 33.

[0056] In some cases, the end of the fixing member 31 away from the abutting portion 311 is provided with a first threaded structure 8, and the butt joint groove 71 is provided with a second threaded structure 9 threadedly connected with the first threaded structure 8. By threadedly connecting the first threaded structure 8 and the second threaded structure 9, the end of the fixing member 31 away from the abutting portion 311 is fixedly connected with the shell 1, and the stable connection between the fixing member 31 and the shell 1 can effectively reduce the shaking of the fixing member 31 caused by vibration, thereby reducing the shaking of the antenna body 2.

[0057] In actual use, the fixing member 31 can be rotated to cooperate the first threaded structure 8 with the second threaded structure 9, so as to finally take out the fixing member 31 from the butt joint groove 71, thereby facilitating maintenance and replacement of the anti-vibration assembly 3.

[0058] In one specific embodiment, the shell 1 can include an upper shell 11, a lower shell 12, and a buffer sealing ring 13, and the upper shell 11 and the lower shell 12 are sealingly connected through the buffer sealing ring 13. The buffer sealing ring 13 can realize sealing between the interior of the shell 1 and the outside, and also provide a certain damping effect. The upper shell 11, the lower shell 12, and the buffer sealing ring 13 can be connected through buckling.

[0059] In this embodiment, the end of the fixing member 31 away from the abutting portion 311 can be fixedly connected with the upper shell 11 or the lower shell 12.

[0060] In summary, the utility model provides a kind of anti-vibration antenna, based on the vertical penetration of fixed part 31 antenna body 2, so that antenna body 2 is limited to only vertically movable.When external vibration force in other direction is applied, due to the radial limiting effect of fixed part 31, antenna body 2 cannot occur transverse or deflection displacement, so as to maintain the basic stability in the structure level, effectively inhibit the direct impact of non-vertical vibration on antenna body 2.And since fixed part 31 is also sleeved with first elastic member 32 and second elastic member 33, and first elastic member 32 and second elastic member 33 are arranged on the upper and lower sides of the vertical direction of antenna body 2, when vertical vibration causes displacement of antenna body 2, it will interact with elastic element, i.e.compress first elastic member 32 on the upper side when vibrating upward, and extrude second elastic member 33 on the lower side when vibrating downward.Through the elastic deformation of elastic element to absorb vibration energy, mechanical vibration is converted into elastic potential energy, and then energy is released through elastic recovery process to form dynamic balance of vibration buffering.In this way, through the design of elastic element, antenna body 2 maintains reasonable dynamic response range in vertical direction, avoiding rigid collision and preventing excessive displacement, and finally realizing significant attenuation of vibration amplitude.Therefore, the embodiment of the application realizes the synergistic effect of mechanical limiting and elastic buffering, radial limiting to inhibit transverse vibration, and axial elastic buffering to attenuate vertical vibration.This multi-dimensional anti-vibration protection system enables the antenna to adapt to complex vibration environment, ensuring the stability of its spatial position and the reliability of its electrical performance.
