It should be understood that when an element is said to be "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or there can be an intermediate element.

[0031] The existing antenna sensor mounting bracket has the following problems:

[0032] 1. Versatility of structural design

[0033] Existing antenna sensor mounting brackets are either different mounting brackets for different antenna configurations, which are simple in design but lack versatility and are not cost-effective; or they are designed as universal mounting brackets that can be adjusted front, back, left, and right, but have complex structures and are relatively bulky.

[0034] 2. Installation location and installation difficulty

[0035] Existing antenna sensor mounting brackets are generally installed on top of base station antennas. Construction workers must climb to the top of the antenna to be installed, which makes installation very difficult. Faced with the huge volume of existing base station antennas in the existing network, the difficulty of installation and maintenance is a very serious problem.

[0036] 3. Measurement accuracy

[0037] The existing antenna sensors installed on top of the base station antenna are exposed to extreme weather such as wind, rain, ice and snow for a long time. It is easy for some parts to become loose, which may cause the relative position of the antenna to be measured to change, introduce changes in the measurement reference, and ultimately affect the measurement accuracy.

[0038] Based on the problems existing in the prior art, it is necessary to fully consider factors such as versatility, reliability, and cost-effectiveness while ensuring performance, which puts forward higher requirements on the structural design of the antenna sensor mounting bracket. In order to solve the above problems, the utility model provides a universal mounting bracket for antenna sensors that is highly versatile, easy to install, and highly reliable. The following is a detailed description through specific embodiments.

[0039] The utility model provides an antenna sensor mounting bracket. Figure 1 and Figure 5 As shown, the antenna sensor mounting bracket 100 includes: a support rod 101 and two sets of clamping components 102 sleeved on the support rod 101.

[0040] The support rod 101 is specifically a universal main support rod, on which the antenna sensor 200 is fixed; the support rod 101 is located behind the antenna body of the base station antenna. The antenna body of the base station antenna can also be called an antenna box, and the antenna body has a front surface, a back surface, a top surface, a bottom surface, and left and right side surfaces.

[0041] The two sets of clamping components 102 are symmetrically designed, arranged opposite to each other with an adjustable distance, and clamped on the two sides of the antenna body of the base station antenna (ie, the left and right sides of the antenna body). At this time, the antenna sensor is located behind the antenna body.

[0042] In this embodiment, the antenna sensor is fixed by a support rod located behind the antenna body of the base station antenna, and then clamped on the two sides of the antenna body of the base station antenna by two sets of clamping components, so that the antenna sensor can be fixed behind the antenna body. Compared with the prior art of installing the mounting bracket of the antenna sensor on the top of the base station antenna, the construction difficulty is reduced. In the face of extreme weather such as wind, rain, ice and snow, the impact of the external environment on the rear antenna sensor can also be reduced due to the shielding protection of the front antenna body. Moreover, by adjusting the spacing between the two sets of clamping components, antenna bodies of different sizes can be adapted, with good versatility, simple structure, and easy installation and maintenance.

[0043] In a specific embodiment, Figure 2 As shown, each set of clamping assembly 102 includes: a clamping plate 1021 sleeved on the support rod 101, a positioning sleeve 1022 and a tightening sleeve 1023.

[0044] The inner surface of the clamping plate 1021 faces the side of the antenna body of the base station antenna, so the two clamping plates 1021 of the two sets of clamping assemblies 102 are clamped on the left and right sides of the antenna body of the base station antenna; the outer end of the clamping plate 1021 is connected to one end of the positioning sleeve 1022. The other end of the positioning sleeve 1022 is provided with an elastic sheet 1024, and the outer surface (outer circle) of the positioning sleeve 1022 is provided with an external thread corresponding to the area between the elastic sheet 1024 and the clamping plate 1021, and the inner surface (inner circle) of the tight hoop 1023 is provided with an internal thread.

[0045] like Figure 3 As shown, the tightening sleeve 1023 is rotated so that its inner surface (inner wall) presses the elastic sheet 1024 on the positioning sleeve 1022, and is connected to the outer surface of the positioning sleeve 1022 through threads to achieve the positioning purpose.

[0046] In this embodiment, the clamping plate 1021 is fixed on the supporting rod 101 through a positioning sleeve 1022 , a tightening sleeve 1023 and an elastic sheet 1024 .

[0047] In a specific embodiment, the elastic sheet 1024 is provided with multiple pieces, and the multiple elastic sheets 1024 are arranged around the support rod 101, one end of each elastic sheet 1024 is connected to the other end of the positioning sleeve 1022, and the other end of each elastic sheet 1024 is bent toward the direction close to the support rod 101. The elastic sheet 1024 is made of elastic material.

[0048] In this embodiment, by arranging multiple curved elastic sheets at the end of the positioning sleeve, the outer diameter of the end of the positioning sleeve forms a tapered design, which makes it easier to extend into the tight hoop sleeve and be caught by the tight hoop sleeve; moreover, the multiple elastic sheets are compressed to provide a better positioning effect.

[0049] In a specific embodiment, Figure 2 As shown, each set of clamping assembly 102 also includes: a damping sleeve 1025. The damping sleeve 1025 is sleeved on the support rod 101 and is located between the support rod 101 and the elastic sheet 1024 at the other end of the positioning sleeve, and its shape matches the support rod. When the tight hoop 1023 is rotated so that its inner wall presses the elastic sheet 1024 on the positioning sleeve 1022, the elastic sheet 1024 will press the damping sleeve 1025 to be fixed on the support rod 101.

[0050] The damping sleeve 1025 is made of elastic material, and the elastic material may be specifically a silicone material.

[0051] In this embodiment, a damping sleeve is provided between the support rod and the positioning sleeve, and the damping sleeve can only slide on the support rod but cannot rotate around the support rod, so that a flexible connection is formed between the support rod and the positioning sleeve, thereby avoiding mechanical resonance.

[0052] In a specific embodiment, an anti-retraction structure is provided at the ends of the tightening sleeve 1023 and the positioning sleeve 1022 close to each other, and the anti-retraction structure is used to prevent the tightening sleeve from rotating in the opposite direction and retreating after the tightening sleeve 1023 and the positioning sleeve 1022 are threadedly connected.

[0053] In this embodiment, since both sets of clamping assemblies are provided with anti-retraction structures, it is ensured that the two clamping plates are always kept in a clamped state, preventing the clamping assemblies from loosening and preventing the clamping force of the two clamping plates on the two sides of the antenna body from weakening, thereby preventing the relative position of the antenna sensor and the antenna to be measured from changing, and will not change the measurement reference, and will not affect the measurement accuracy of the antenna sensor.

[0054] In an alternative embodiment, if Figure 3 and Figure 4 As shown, the anti-retraction structure includes: a raised one-way bone 10231 provided on the tight hoop 1023, and a raised positioning bone 10221 provided on the positioning sleeve 1022. The positioning bone 10221 on the positioning sleeve 1022 protrudes outward at the end close to one side of the tight hoop, and a clamping groove is provided at the end close to one side of the positioning sleeve of the one-way bone 10231 on the tight hoop 1023. The tight hoop 1023 is rotated until the protruding part of the positioning bone 10221 on the positioning sleeve 1022 slides into the clamping groove of the one-way bone 10231 and is clamped by the clamping groove of the one-way bone 10231 and cannot be rotated in the reverse direction.

[0055] Specifically, the one-way bone 10231 can be a long strip structure, which is arranged on the outer surface of the tight hoop 1023 and extends to both ends of the tight hoop 1023 along the length direction of the tight hoop 1023, and the clamping groove is arranged at the end of the tight hoop 1023 corresponding to the area of ​​the one-way bone 10231. The positioning bone 10221 can also be a long strip structure, which is arranged on the outer surface of the positioning sleeve 1022 corresponding to the area between its external thread and the clamping plate 1021, and extends along the length direction of the positioning sleeve 1021.

[0056] Furthermore, the shape of the outwardly extending portion of the end of the positioning bone 10221 can be a fingertip shape placed sideways, and the extending portion can also be called a fingertip portion, and the shape of the one-way bone slot matches the shape of the outwardly extending portion of the positioning bone.

[0057] In this embodiment, while the tight hoop sleeve is rotating, the slot of the one-way bone and the positioning bone gradually approach each other. At this time, the tight hoop sleeve can be rotated in both forward and reverse directions. The tight hoop sleeve continues to be rotated until the part of the positioning bone that protrudes outward slides into the slot of the one-way bone and is stuck. At this time, the tight hoop sleeve cannot rotate in the opposite direction, and the positioning bone sticks to the one-way bone, thereby realizing the clamping limit of the one-way bone and the positioning bone, thereby preventing the tight hoop sleeve from rotating in the opposite direction and retreating.

[0058] In another optional embodiment, the anti-retraction structure includes: a plug (not shown in the figure) disposed at the end where the tight sleeve 1023 and the positioning sleeve 1022 are close to each other. The plug includes an insertion portion disposed at the end of the tight sleeve 1023 and a fixing portion disposed at the end of the positioning sleeve 1022, or the plug includes a fixing portion disposed at the end of the tight sleeve 1023 and an insertion portion disposed at the end of the positioning sleeve 1022. After the tight sleeve 1023 is rotated until it reaches a preset position on the positioning sleeve 1022, the insertion portion is inserted into the fixing portion to prevent the tight sleeve 1023 from rotating in the opposite direction and retracting.

[0059] In this embodiment, the bolt can also be used to prevent the tight collar from rotating in the opposite direction and retreating.

[0060] In another optional embodiment, the anti-retraction structure includes: a stop screw (not shown in the figure) arranged at the end where the clamp sleeve 1023 and the positioning sleeve 1022 are close to each other. The stop screw includes a bolt arranged at the end of the clamp sleeve 1023 and a nut arranged at the end of the positioning sleeve 1022, or the stop screw includes a nut arranged at the end of the clamp sleeve 1023 and a bolt arranged at the end of the positioning sleeve 1022. After the clamp sleeve 1023 is rotated until it reaches a preset position on the positioning sleeve 1022, the bolt and the nut are threadedly connected to prevent the clamp sleeve 1023 from rotating in the opposite direction and retreating. Among them, an upright washer can be arranged at the end of the clamp sleeve or the positioning sleeve, and the bolt is connected to the nut after passing through the washer.

[0061] In this embodiment, the stop screw can also prevent the tightening sleeve from rotating in the opposite direction and retreating.

[0062] In a specific embodiment, Figure 2 As shown, the support rod 101 is a hollow rod-shaped structure, and its cross section is elliptical or rectangular (square or rectangular), or a shape similar to an ellipse.

[0063] In this embodiment, the cross-section of the support rod is not circular, but elliptical or rectangular, which mainly serves to initially limit the clamping assembly mounted on the support rod to prevent the clamping assembly from rotating and sliding on the support rod. Of course, the cross-section of the support rod can also be of other shapes as long as it can play a limiting role.

[0064] Specifically, the support rod 101 can be made of a hollow stainless steel tube. Of course, the support rod can also be made of other materials as long as a certain strength is guaranteed.

[0065] In a specific embodiment, Figure 5 As shown, two positioning holes are respectively provided at both ends of the support rod 101, and two GPS (Global Positioning System) antenna boxes 202 of the antenna sensor 200 are fixed on the support rod 101 through the two positioning holes. The sensor main control box 201 of the antenna sensor is fixed in the middle of the support rod 101 by means of a snap connection.

[0066] In this embodiment, Figure 5 The left and right GPS antenna boxes shown are respectively installed at the two positioning holes at both ends of the support rod by screws, and the middle sensor main control box is fixed in the middle of the support rod by snapping.

[0067] The antenna sensor mounting bracket provided in the embodiment of the utility model fixes the antenna sensor through a support rod, and can mount antenna sensors of different sizes according to different needs, and then clamp it on the two sides of the antenna body of the base station antenna through two sets of clamping components, so that the antenna sensor can be flexibly installed at any position behind the antenna body according to the spatial position of the base station antenna on site, and the installer does not have to climb to the top of the antenna to install and fix it, which reduces the construction difficulty accordingly. Moreover, the mounting bracket with integrated antenna sensor can be applied to base station antennas of various sizes at present by adjusting the spacing between the clamping components on the left and right sides, and has strong versatility. Compared with the traditional antenna sensor mounting bracket, the mounting bracket described in the utility model has the advantages of simple structure, convenient installation, strong versatility and high reliability.

[0068] The present utility model also provides a base station antenna. Figure 6 As shown, the base station antenna includes: an antenna body 300 , an antenna sensor 200 and an antenna sensor mounting bracket 100 .

[0069] The antenna sensor mounting bracket 100 includes a support rod and two sets of clamping components with adjustable spacing.

[0070] The antenna sensor 200 is fixed on the support rod of the antenna sensor mounting bracket 100. Figure 5 As shown, the antenna sensor 200 includes a sensor main control box 201 and two left and right GPS antenna boxes 202 .

[0071] Two GPS antenna boxes 202 are respectively fixed by screws at two positioning holes at both ends of the support rod 101. The GPS antenna box is a part of the antenna sensor, and is equipped with a GPS antenna for receiving GPS satellite signals.

[0072] The sensor main control box 201 is fixed to the middle of the support rod by snap-fitting. A small hole is provided in the middle of the support rod 101, and the shape of the small hole can be elliptical. After the communication cable led out of the sensor main control box 201 extends into the support rod 101 through the small hole, it is divided into two parts and extends in the support rod 101 toward its two ends, until it extends from both ends of the support rod 101, and then connects to the left and right GPS antenna boxes 202, so as to realize the communication between the sensor main control box 201 and the left and right GPS antenna boxes 202.

[0073] The two sets of clamping components of the antenna sensor mounting bracket 100 are clamped on the two sides of the antenna body 300 (i.e. Figure 6 The left and right sides of the antenna body 300 are symmetrically arranged on the left and right sides of the antenna body 300. The support rod of the antenna sensor mounting bracket 100 and the two sets of clamping components with adjustable spacing work together to ensure that the antenna sensor can be fixedly connected to antenna bodies (antenna boxes) of various sizes.

[0074] After the antenna sensor 200 is fixed on the support rod and two sets of clamping components are clamped on the two sides of the antenna body 300, the antenna sensor is located behind the antenna body 300, and the position of the antenna sensor 200 behind the antenna body 300 can be adjusted as needed.

[0075] The base station antenna provided in the embodiment of the utility model can carry antenna sensors of different sizes through a universal antenna sensor mounting bracket, and the mounting bracket realizes a clamping plate installation method for installing the antenna sensor on the back of the antenna body, which can adapt to antenna bodies of different sizes.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
