Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to an antenna device. Background Art

[0002] Antennas are widely used in radio systems such as communications, broadcasting, television, radar, and navigation. They propagate radio waves and are essential for effectively radiating and receiving them. Array antennas, consisting of many identical individual antennas (such as symmetrical antennas) arranged in a regular pattern, are also called antenna arrays. The individual units that make up an antenna array are called array elements or antenna units. If the array elements are arranged in a straight line or a plane, it is called a linear array or a planar array.

[0003] Existing large-scale array electrically steered antennas are typically installed outdoors for extended periods of time. However, due to the complexity of the external environment, they must withstand constant environmental testing, such as rain, snow, strong winds, and even frequent collisions with flying objects. These conditions often damage the antennas, leading to communication interruptions and a lack of adequate protection. The current solution is to strengthen the outer casing, but this reinforced casing can also hinder signals, affecting the antenna's normal signal coverage. Furthermore, the reinforced casing increases the weight of the entire device, making it difficult to install and use. Summary of the Invention

[0004] The present invention provides an antenna device for solving the problem of poor protection measures for current large-scale array electrically adjustable antennas.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An antenna device comprises: a shell, the shell having a protective cavity and at least one retractable hole, the retractable hole connecting the protective cavity with the outside world, and the protective cavity being used to protect the device inside the shell; a communication device, arranged in the protective cavity and fixedly connected to the shell, mainly storing and transmitting antenna signals; a traction assembly, arranged in the protective cavity, and the traction assembly is slidably connected to the shell and can slide along a first straight line direction; a driving assembly, arranged in the protective cavity, the driving assembly is connected to the shell and to the traction assembly, and is used to drive the traction assembly to slide along the first straight line direction; and at least one antenna assembly, one antenna assembly is inserted into one of the retractable holes, the antenna assembly comprises a first end and a second end arranged at intervals, the first end of the antenna assembly is located in the protective cavity and connected to the traction assembly, the second end of the antenna assembly passes through the retractable hole, and the first straight line direction is consistent with the extension direction of the center line of the retractable hole.

[0007] The present invention provides an antenna device, wherein an outer shell protects the device equipment inside the outer shell, the communication equipment inside the outer shell is mainly used for storing and transmitting signals, the outer shell is used to protect the internal equipment, the antenna assembly extending from the outer shell is used for receiving signals, and the traction assembly is used to connect the outer shell and the antenna assembly to facilitate the retraction of the antenna assembly. When the antenna assembly outside needs to be retracted, the driving assembly drives the traction assembly to move along a first straight line direction, thereby driving the antenna assembly connected to the traction assembly to move as well, thereby realizing the retraction of the antenna assembly. After the antenna assembly is retracted into the outer shell, the entirety is inside the outer shell, which can greatly reduce the damage caused to the antenna assembly under the influence of harsh environments and flying objects, and has good protective performance.

[0008] Furthermore, the traction assembly includes a traction plate disposed within the housing and slidably connected thereto for convenient up and down movement. At least one first elastic member is disposed beneath the housing. A first end of the antenna assembly is connected to the first elastic member and can move with the traction plate, thereby driving the antenna assembly to complete retraction and extension. Furthermore, the use of the first elastic member to connect the antenna assembly prevents the antenna assembly from being physically damaged during retraction, which could result in damage. Once retracted from the housing, the entire antenna assembly is contained within the protective cavity, thereby protecting the antenna assembly.

[0009] Furthermore, the traction assembly further includes at least one sliding member, which is slidably connected to the traction plate, arranged below the traction plate, and slidable along a second straight line direction. The first straight line direction is perpendicular to the second straight line direction. The first elastic member is connected to one of the sliding members. When the antenna assembly is retracted, the sliding member can adaptively move on the traction plate, and the antenna assembly can be dragged into the shell more smoothly to complete the retraction.

[0010] Furthermore, the antenna assembly extends from the first end to the second end along an arc direction, the first end and the second end are spaced apart in the first straight line direction, and the first end and the second end are spaced apart in the second straight line direction, that is, the antenna assembly is an arc-shaped structure, and is tilted when in use. Since the arc-shaped structure occupies a smaller straight-line distance, the length of the antenna assembly can be set longer, more signal antennas can be carried on the antenna assembly, and there is less signal interference. The arc-shaped structure can also be conveniently entered and exited from the shell.

[0011] Furthermore, at least one adjustment component is provided at the receiving hole, wherein a first slot and a second slot are provided on a wall surface of the receiving hole and are oppositely arranged in a second straight line direction. The adjustment component further comprises a second elastic member and a third elastic member, wherein the second elastic member is provided in the first slot and the third elastic member is provided in the second slot; a first adjustment member and a second adjustment member, wherein the first adjustment member and the second adjustment member are spaced apart, and the antenna assembly is located between the first adjustment member and the second adjustment member;

The first adjusting member is located on the other side of the second elastic member. A portion of the first adjusting member extends out of the first slot and contacts the antenna assembly, while the other portion is located within the first slot and compresses the second elastic member. The second adjusting member is rotatable and movable along a second linear direction to engage with the second slot. The second adjusting member is located on the other side of the third elastic member. A portion of the second adjusting member extends out of the second slot and contacts the antenna assembly, while the other portion is located within the second slot and compresses the third elastic member. The first adjusting member, in conjunction with the second elastic member, and the second adjusting member, in conjunction with the third elastic member, adaptively clamp the antenna assembly in place without affecting the movement of the antenna assembly.

When the driving component moves between the first connecting plate and the second connecting plate, it drives the above-mentioned traction plate to move, so that the traction plate drives the antenna assembly to move.

[0014] Furthermore, one of the first connecting plate and the second connecting plate is provided with a plurality of teeth, and the teeth are arranged along the first straight line direction; the driving assembly includes a gear and a driving motor, the gear is engaged with the plurality of teeth of one of the first connecting plate and the second connecting plate, the driving motor is connected to the gear, and the driving motor is fixedly connected to the traction plate, the driving motor and the driving gear drive the gear to move along the first straight line direction on one of the first connecting plate and the second connecting plate, and the traction plate moves along the first straight line direction driven by the gear.

[0015] Furthermore, at least one avoidance hole is provided on the traction plate, and the position of the avoidance hole corresponds to the position of the communication device. When the traction plate moves, the communication device can be avoided. Therefore, the traction plate can move unimpeded in the shell, making it easy to retract and extend the antenna assembly.

[0016] Furthermore, the antenna assembly further includes: an antenna mount, the antenna mount coinciding with the first and second ends of the antenna assembly, the first end of the antenna mount being connected to the first elastic member; a limiting groove being provided on a surface of at least one side in the third straight line direction, a limiting member being slidably connected within the limiting groove, and the other end of the limiting member being fixed to the housing, such that the fixing of the limiting member ensures that the retraction trajectory of the antenna mount is fixed and stable; the antenna mount is further provided with a plurality of single antennas, which are electrically connected to the communication device, and after receiving a signal, the single antenna stores the communication data in the communication device and transmits the data via the communication device;

[0017] The antenna rack is also provided with a detector for detecting changes in the external environment and is electrically connected to the drive assembly. When the detector detects that the external environment affects the normal use of the antenna assembly, the drive assembly is controlled to operate and the antenna assembly is retracted in time.

[0018] Furthermore, the surface of the antenna rack is provided with a mounting groove on at least one side in the thickness direction: a single antenna is installed in the mounting groove, and the mounting groove can make the single antenna more safely set on the antenna rack, and a wiring channel is provided inside the antenna rack, and the single antenna is connected to the communication equipment through the signal line passing through the wiring channel to transmit the signal; at the same time, a plurality of buffer structures are also provided on the antenna rack, and the above-mentioned buffer structure is provided between the single antenna and the mounting groove, and a buffer structure is provided between each single antenna and the mounting groove, and the above-mentioned buffer structure can reduce the damage of the antenna rack and the single antenna when subjected to external force.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] The present invention provides an antenna device, such as Figure 1 As shown, the device includes a housing 110, which is enclosed on all sides and defines a protective cavity 160 and at least one retractable hole 130 within the housing 110. The retractable hole 130 is used to connect the protective cavity 160 with the outside world. A mounting bracket 120 is also provided on the side of the housing 110 for mounting the housing 110 in a fixed position. A communication device 150 is disposed within the housing 110 and is generally mounted and fixed to the inner side of the housing 110. The communication device 150 is used to store signals transmitted by the antenna assembly 400 and transmit the signals.

[0034] On this basis, a traction component 200 is further provided in the housing 110, the traction component 200 is slidably connected to the housing 110, the traction component 200 is connected to the driving component 300, and the antenna component 400 is connected below the traction component 200. The traction component 200 is driven by the driving component 300 to move inside the housing 110, and the moving direction is the first linear direction, such as Figure 1 As shown, the up and down directions are shown in the figure, and the traction component 200 drives the antenna component 400 to move during the movement.

[0035] Furthermore, at least one antenna assembly 400 is provided, and the number of antenna assemblies 400 is the same as the number of retractable holes 130. One antenna assembly 400 is passed through one retractable hole 130. The antenna assembly 400 includes a first end and a second end spaced apart, wherein the first end of the antenna assembly 400 is located in the protective cavity 160 and is connected to the traction assembly 200. The second end of the antenna assembly 400 passes through the retractable hole 130. When the antenna assembly 400 is in the extended state, the second end of the antenna assembly 400 is in the outside world. When the antenna assembly 400 is in the retracted state, the second end of the antenna assembly 400 is in the protective cavity 160. In addition, the center line of the retractable hole 130 is consistent with the direction of the first straight line.

[0036] The housing 110 may be a box structure, such as Figure 2As shown, the housing 110 is a box structure, which is easy to install and fix on the outside, and the inside of the box structure is also convenient for installing and fixing other components. At the same time, the box structure also facilitates protecting the entire device after the antenna assembly 400 is retracted. Of course, the housing 110 can also be any other suitable structure.

[0037] Furthermore, the retractable hole 130 may be provided with one, and used in conjunction with one antenna assembly 400, and its signal coverage range is relatively small. Figure 1 As shown, there can be multiple retractable holes 130 and multiple antenna assemblies 400. Each retractable hole 130 is provided with an antenna assembly 400, that is, a shell 110 is equipped with multiple groups of antenna assemblies 400, which can greatly improve the coverage range and ensure signal strength and quality.

[0038] In some embodiments of the present application, the antenna assembly 400 is a plate-like structure, and the width of the retracting hole 130 is greater than the thickness of the antenna assembly 400, so that the antenna assembly 400 can smoothly enter and exit the retracting hole 130 when tilted.

[0039] In other embodiments of the present application, Figure 3 As shown, an adjustment assembly 140 is further provided at the receiving hole 130. At least one adjustment assembly 140 is provided, with one adjustment assembly 140 provided at each receiving hole 130. Furthermore, a first slot 141 and a second slot 144 are provided on the wall surface of the receiving hole 130, oppositely disposed in a second linear direction. That is, the first slot 141 and the second slot 144 are provided on either side of the receiving hole 130, and the first slot 141 and the second slot 144 are disposed oppositely. The second linear direction is perpendicular to the first linear direction.

[0040] Among them, a first adjusting member 143 is provided in the first slot 141, the other end of the second elastic member 142 is provided with the first adjusting member 143, the second slot 144 is provided with a third elastic member 145, the other end of the third elastic member 145 is provided with a second adjusting member 146, and the above-mentioned antenna assembly 400 is provided between the first adjusting member 143 and the second adjusting member 146.

[0041] On this basis, the first adjusting member 143 is rotatable and movable along the second linear direction to engage with the first slot 141 , with a portion of the first adjusting member 143 extending out of the first slot 141 to contact the antenna assembly 400 , while the other portion is within the first slot 141 and compresses the second elastic member 142 ;

[0042] The second adjusting member 146 is rotatable and movable along the second linear direction to cooperate with the second slot 144 , and a portion of the second adjusting member 146 extends out of the second slot 144 to contact the antenna assembly 400 , while the other portion is in the second slot 144 and squeezes the third elastic member 145 .

[0043] By cooperating with the elastic parts and the adjusting parts on both sides of the retracting hole 130, the antenna assembly 400 is clamped from both sides. During clamping, since the elastic parts are under pressure, the adjusting parts can automatically adapt to the position and angle of the antenna assembly 400, protect the entry and exit of the antenna assembly 400, and ensure that the antenna assembly 400 moves stably.

[0044] The first and second adjusting members 143, 146 can be mounted within the first and second slots 141, 144 and freely move within them. Specifically, movable rails are provided within the first and second slots 141, 144, and the first and second adjusting members 143, 146 are mounted on the rails for movement. It should be noted that limiters are also provided within the first and second slots 141, 144 to limit the first and second adjusting members 143, 146 and prevent them from moving outside the range of the first and second slots 141, 144. The first and second adjusting members 143, 146 engage the antenna assembly 400 from both sides, preventing the antenna assembly 400 from contacting the sidewalls of the retraction hole 130 during retraction and extension, which could damage the antenna assembly 400. Of course, the first and second adjusting members 143, 146 can also be movably connected to the first and second slots 141, 144 in other suitable manners.

[0045] In some embodiments of the present invention, the second elastic member 142 and the third elastic member 145 may be springs. The springs have a simple structure and are easy to purchase and replace. They can also compress the first adjusting member 143 and the second adjusting member 146, ensuring that the first adjusting member 143 and the second adjusting member 146 are in constant contact with the antenna assembly 400, thereby protecting the antenna assembly 400 from entry and exit. Of course, the second elastic member 142 and the third elastic member 145 may also be other elastic members that meet the requirements.

[0046] In some embodiments of the present invention, the first adjusting member 143 and the second adjusting member 146 may be rollers, which are engaged in the first slot 141 and the second slot 144 and can both rotate and move in the first slot 141 and the second slot 144 .

[0047] In other embodiments of the present invention, the first adjusting member 143 and the second adjusting member 146 may be a moving block and a rotating wheel connected to the moving block. The rotating wheel is directly connected to the moving block and is moved by the moving block within the first slot 141 and the second slot 144. The rotating wheel contacts the antenna assembly 400 and can also protect the antenna assembly 400 during retraction and extension. Alternatively, the first adjusting member 143 and the second adjusting member 146 may be other adjusting members that meet the requirements.

[0048] In some embodiments of the present invention, a plurality of adjustment components 140 are provided in a retractable hole 130, and the adjustment components 140 are evenly distributed in the retractable hole 130, and the antenna component 400 is clamped in the width direction of the antenna component 400 to ensure that the antenna component 400 does not collide with the retractable hole 130 during the entry and exit process, causing damage.

[0049] Based on this, Figure 1 As shown, the traction assembly 200 includes a traction plate 210, which is a plate-shaped structure and is slidably connected to the housing 110. At least one first elastic member 220 is disposed below the traction plate 210. The other end of the first elastic member 220 is connected to one end of the antenna assembly 400. The antenna assembly 400 is retracted and extended from the retraction opening 130. When the traction plate 210 moves up and down, the connection of the first elastic member 220 drives the antenna assembly 400 to be retracted and extended simultaneously.

[0050] As can be seen from the above, the antenna assembly 400 is connected using the first elastic member 220. During the retraction process of the antenna assembly 400, if it encounters external force jamming at the retracting opening 130 or the retracting opening 130 is blocked, the first elastic member 220 can make the antenna assembly 400 adaptively fine-tuned and float up and down to get rid of the jam, or the retracting opening 130 can be cleared with the help of the up and down floating of the antenna assembly 400, so that the antenna assembly 400 can smoothly enter the interior of the shell 110.

[0051] It should be noted that each antenna assembly 400 is connected to at least one first elastic member 220. When the antenna assembly 400 is too large, multiple first elastic members 220 need to be connected to the antenna assembly 400 to ensure a stable connection between the antenna assembly 400 and the traction plate 210.

[0052] In some embodiments of the present invention, the first elastic member 220 may be a spring. The spring has a simple structure and is easy to purchase and replace. When the antenna assembly 400 is retracted, it can be adaptively fine-tuned to allow the antenna assembly 400 to smoothly enter the interior of the housing 110. The first elastic member 220 may also be other elastic members that meet the requirements.

[0053] In some embodiments of the present invention, a sliding member 211 is further provided under the above-mentioned traction plate 210. The sliding member 211 is slidably connected to the above-mentioned traction plate 210 and can slide along a second straight line direction. The first straight line direction is perpendicular to the second straight line direction. The above-mentioned first elastic member 220 is connected to the sliding member 211. Using the sliding member 211 to connect the first elastic member 220 can make the first elastic member 220 adaptively move on the traction plate 210 when pulling the antenna assembly 400. When encountering external force or blockage of the retracting port 130, the affected adjustment can be made, so that the antenna assembly 400 can be more conveniently and smoothly dragged into the interior of the shell 110.

[0054] Specifically, the sliding member 211 can be a combination of a slide rail and a slider. The slide rail is arranged below the traction plate 210, and the arrangement direction is the second straight line direction. The slider is clamped on the slide rail, and the slider is connected to the first elastic member 220 below. One slider is connected to one first elastic member 220, which can meet the requirement that the first elastic member 220 can adaptively move on the traction plate 210 when pulling the antenna assembly 400.

[0055] In this method, the slider is directly connected to the slide rail. Since the load-bearing capacity of the connection between the slider and the slide rail is poor, the antenna assembly 400 connected below should not be too heavy. If the load-bearing capacity is too heavy, the slider may be damaged and unable to slide, thereby affecting the entry and exit of the antenna assembly 400, causing the antenna assembly 400 to get stuck when entering and exiting. In severe cases, it may even cause damage to the antenna assembly 400, resulting in problems with signal transmission.

[0056] Based on the above situation, when the connected antenna assembly 400 is heavy, the above-mentioned sliding member 211 can be a combination of a slide rail, a connecting pulley and a slider, which is clamped in the slide rail by the connecting pulley and can move freely in the slide rail. The slider is connected to the connecting pulley, and the slide rail and the slider are connected with the help of the connecting pulley. The connecting pulley has a large load-bearing capacity and is not easily damaged, and can support a larger and heavier antenna assembly 400.

[0057] Specifically, the traction plate 210 extends along the second straight line direction. When there is only one antenna assembly 400 connected, the traction plate 210 is located in the middle of the outer shell 110. When there are multiple antenna assemblies 400 connected, the traction plate 210 extends from the middle of the outer shell 110 to both sides of the second straight line direction and is connected to multiple antenna assemblies 400.

[0058] On this basis, if Figure 4As shown, the above-mentioned shell 110 includes a main shell 111, a protective cavity 160 and a retracting hole 130 are arranged on the main shell 111, and a mounting frame 120 is also arranged on the main shell 111. A first connecting plate 310 and a second connecting plate 330 are arranged inside the main shell 111. The first connecting plate 310 and the second connecting plate 330 are arranged at intervals, and the driving component 300 is connected to one of the above-mentioned first connecting plate 310 or the second connecting plate 330. The driving component 300 can move along the first straight line direction, and the driving component 300 is connected to the above-mentioned traction plate 210. The driving component 300 drives the traction plate 210 to move while moving.

[0059] On the basis of the above structure, the traction plate 210 is slidably connected to the above shell 110. The traction plate 210 moves up and down in the shell 110 and needs to be slidably connected to the shell 110 to limit its position to ensure that it does not deviate or flip during the movement. In some embodiments of the present invention, such as Figure 5 As shown, the traction plate 210 is slidably connected to the first connecting plate 310 and the second connecting plate 330, and two staggered holes passing through the first connecting plate 310 and the second connecting plate 330 are provided on the traction plate 210, and a plurality of grooves are provided on the two staggered holes, which are provided on the back sides corresponding to the first connecting plate 310 and the second connecting plate 330. The above-mentioned driving assembly 300 is provided between the first connecting plate 310 and the second connecting plate 330, and convex strips are provided on the first connecting plate 310 and the second connecting plate 330 at positions corresponding to the grooves. The convex strips are arranged along the first straight line direction, and the convex strips are connected with the grooves and can slide relative to each other, so that the traction plate 210 can move along the convex strips when moving, guide the moving direction of the traction plate 210, and prevent the traction plate 210 from deviating from the moving trajectory.

[0060] At this time, the pulling plate 210 may not contact the inner wall of the housing 110 , but may be only slidably connected to the first connecting plate 310 and the second connecting plate 330 , and may move under the guidance of the convex strips.

[0061] In other embodiments of the present invention, Figure 6 As shown, the traction plate 210 is slidably connected to the main shell 111, and two offset holes are provided on the traction plate 210, which pass through the first connecting plate 310 and the second connecting plate 330. A plurality of protrusions are provided on the outer wall of the traction plate 210, and grooves are provided at corresponding positions on the inner wall of the main shell 111. The grooves are arranged along the first straight line direction. At this time, the outer side of the traction plate 210 contacts the inner wall of the main shell 111, and the protrusions and the grooves are matched and connected, and can slide relative to each other. In this way, the traction plate 210 can move along the groove when moving, guiding the moving direction of the traction plate 210 to prevent the traction plate 210 from deviating from the moving trajectory.

[0062] At this time, the traction plate 210 needs to contact the inner wall of the shell 110, and its protrusion needs to contact and cooperate with the groove of the shell 110, and moves under the guidance of the protrusion.

[0063] Specifically, one of the first connecting plate 310 and the second connecting plate 330 is provided with a plurality of teeth along the first straight line direction, such as Figure 4 As shown, the teeth are arranged on a side of the first connecting plate 310 close to the second connecting plate 330 . At this time, the driving assembly 300 is disposed between the first connecting plate 310 and the second connecting plate 330 .

[0064] On this basis, if Figure 7 As shown, the drive assembly 300 includes a drive motor 340, which is fixedly connected to the traction plate 210. The output shaft of the drive motor 340 is connected to a gear 320. The gear 320 meshes with the teeth on the first connecting plate 310. The second connecting plate 330 limits the gear 320. At this time, the distance between the first connecting plate 310 and the second connecting plate 330 is equal to the diameter of the tooth tip circle of the gear 320, ensuring that the gear 320 does not deviate from the running trajectory during movement. To prevent the gear 320 from deviating from the movement trajectory, the drive motor 340 drives the gear 320 to move on the first connecting plate 310, thereby driving the traction plate 210 to move. Because the traction plate 210 is connected to the antenna assembly 400, the antenna assembly 400 can be retracted and extended.

[0065] Furthermore, in order to ensure that the driving assembly 300 is stably connected to the traction plate 210, as shown in FIG. Figure 7 As shown, the gear 320 is mounted on a fixing bracket 321 and is rotatable on the fixing bracket 321. The fixing bracket 321 is fixedly connected to the traction plate 210. The drive motor 340 is connected to the traction plate 210 via a fixing base 341. The output shaft of the drive motor 340 is connected to the gear 320. The traction plate 210 is used to support and mount the gear 320 and the drive motor 340. In this way, the drive motor 340 drives the gear 320 to rotate, so that when the gear 320 moves on the first connecting plate 310, it drives the traction plate 210 to move more stably, avoiding malfunction of the drive motor 340.

[0066] In some embodiments of the present invention, the teeth may also be disposed on the side of the second connecting plate 330 closer to the first connecting plate 310. In this case, the drive assembly 300 is disposed between the first connecting plate 310 and the second connecting plate 330. The connection between the drive assembly 300 and the second connecting plate 330 is similar to the connection between the drive assembly 300 and the first connecting plate 310. The gear 320 engages with the teeth on the second connecting plate 330, and the first connecting plate 310 limits the position of the gear 320. In this case, the distance between the first connecting plate 310 and the second connecting plate 330 is equal to the diameter of the tooth tip circle of the gear 320, ensuring that the gear 320 does not deviate from its trajectory during movement.

[0067] The first connecting plate 310 and the second connecting plate 330 can be directly connected and fixed to the upper and lower sides of the main housing 111, and the fixing method can be welding, bolting or other suitable methods. Figure 3 As shown, the first connecting plate 310 and the second connecting plate 330 are connected and fixed to the two side surfaces of the main shell 111 through connecting columns, and the gear 320 is clamped and limited from both sides. The connecting columns are mainly arranged on the four corners of the first connecting plate 310 and the second connecting plate 330, first ensuring the stability of the fixation of the first connecting plate 310 and the second connecting plate 330, and further ensuring the stability of the moving trajectory of the gear 320.

[0068] Furthermore, the drive motor 340 in the drive assembly 300 may be a servo motor. The servo motor can accurately control the movement of the traction plate 210 according to the signal, without any unnecessary displacement affecting the normal operation of the traction plate 210, and can control the up and down movement of the traction plate 210 by forward and reverse rotation. Of course, the drive motor 340 may also be other suitable drive motors 340.

[0069] Furthermore, in order to ensure that the traction plate 210 can move unimpeded in the housing 110, an avoidance hole 212 is opened on the traction plate 210. The position of the avoidance hole 212 corresponds to the communication device 150, ensuring that it can pass through the communication device 150 during the movement without colliding with the communication device, so that the traction plate 210 moves more smoothly.

[0070] In some embodiments of the present invention, the traction plate 210 is shaped as an H-shaped plate structure, and the opening of the H-shaped plate of the traction plate 210 avoids the communication device 150. The use of the H-shaped plate structure reduces the weight of the traction plate 210 while ensuring the strength, making it more convenient to move inside the shell 110.

[0071] In other embodiments of the present invention, the shape of the traction plate 210 can be a field-shaped plate structure or a well-shaped plate structure, both of which ensure the stability of the connection while reducing the weight of the traction plate 210, or the traction plate 210 can also be a traction plate 210 of other suitable shapes while ensuring the strength of the traction plate 210.

[0072] Further, if Figure 8 As shown, the antenna assembly 400 includes an antenna frame 410 connected to the first elastic member 220, one end of the antenna frame 410 forms the first end of the above-mentioned antenna assembly 400, and the other end of the antenna frame 410 forms the second end of the above-mentioned antenna assembly 400, and a limiting groove 430 is provided on the side of the antenna frame 410 along the third straight line direction. The limiting groove 430 extends from the first end to the second end, that is, extends along the antenna frame, and the third straight line direction is in the width direction shown in the figure, perpendicular to the first straight line direction and the second straight line direction. The limiting member 420 is slidably connected in the limiting groove 430, and the other end of the limiting member 420 is fixed on the inner side surface of the main shell 111, so that the entire antenna rack 410 rotates slightly around the limiting member 420, and the fixed position of the limiting member 420 and the main shell 111 is located above the retracting hole 130, so that the antenna rack 410 can be easily moved in and out of the retracting hole 130 while being fixed. At the same time, with the cooperation of the adjustment component 140, the fixed direction of the limiting member 420 and the fixed direction of the adjustment component 140 limit the movement of the antenna rack 410 in the second straight line direction and the third straight line direction, so that the antenna rack 410 can only be controlled to move in the first straight line direction by the traction component 200. Therefore, the movement trajectory of the antenna rack 410 is fixed and stable, ensuring the normal retraction and use of the antenna component 400.

[0073] Specifically, the stopper 420 may be a rubber rod-shaped structure. The rubber has a certain degree of deformability and cushioning capacity, which can transmit and cushion external forces when applied to the antenna mount 410, thereby reducing damage to the antenna mount 410. The outer surface of the rubber rod is also provided with an anti-corrosion coating to mitigate corrosion of the stopper 420 in rainy and snowy weather, thereby increasing its service life. The stopper 420 may also be any other suitable stopper 420 with certain deformability and cushioning capacity.

[0074] In some embodiments of the present invention, the limiting member 420 and the limiting groove 430 may be provided on only one side of the antenna frame 410 along the third straight line direction, that is, the antenna frame 410 is only connected to one side of the main housing 111, and the antenna frame 410 is fixed on one side. Figure 7 As shown, limiting members and limiting grooves 430 are provided on both sides of the antenna rack 410 along the third straight line direction, so that the connection between the antenna rack 410 and the main shell 111 is more stable, and it is also more stable when retracted and released, thereby improving the service life of the antenna rack 410.

[0075] On this basis, a plurality of single antennas 460 are provided on the antenna stand 410 . The single antennas 460 are electrically connected to the communication device 150 to transmit signal data to the communication device 150 for storage.

[0076] Further, if Figure 8 As shown, the single antenna 460 is installed on the antenna rack 410 in the form of a matrix array, which can greatly utilize the space of the antenna rack 410 and improve the signal coverage range.

[0077] Furthermore, the upper and lower sides of the antenna rack 410 are symmetrically arranged, and multiple single antennas 460 are arranged on the upper and lower sides of the antenna rack 410. The symmetrical arrangement of the antenna rack 410 can carry more single antennas 460, thereby expanding the signal coverage range of the antenna assembly 400.

[0078] Furthermore, in order to enable the antenna assembly 400 to be automatically retracted, a detector 440 is also installed on the antenna frame 410. The detector 440 can be set at any position of the antenna frame 410 for detection, or as shown in FIG. Figure 1 As shown, the detector 440 can be set at the end of the antenna frame 410 to more accurately detect changes in the external environment. The detector 440 is electrically connected to the drive motor 340. When the detector 440 detects that the external environment has changed significantly and affects the normal use of the antenna assembly 400, it controls the drive assembly 300 to operate and retract the antenna assembly in time. When the threshold set by the detector 440 is exceeded, the detector 440 transmits a signal to the drive motor 340, which controls the drive motor 340 to operate in the reverse direction, pulling the antenna frame 410 into the housing 110. Because the detector 440 is set at the end of the antenna frame 410, after being retracted into the housing 110, the detector 440 is also close to the retraction hole 130 and can continue to detect the external environment. When the vibration intensity returns to normal, the detector 440 transmits a signal to the drive motor 340, which controls the drive motor 340 to operate in the forward direction, extending the antenna frame 410 back to the outside world for normal signal transmission.

[0079] In some embodiments of the present invention, the detector 440 can be a vibration detector, such as a vibration sensor, and a maximum vibration threshold is set on the vibration sensor. When the vibration intensity detected by the vibration sensor exceeds the set threshold, the vibration sensor transmits a signal to control the drive motor 340 to run in reverse, dragging the antenna frame 410 back to the housing 110. When the detected vibration intensity is less than the set threshold, the drive motor 340 is controlled to run in the forward direction, and then the antenna frame 410 is extended to the outside to achieve precise protection.

[0080] In other embodiments of the present invention, detector 440 may also be other detectors, such as video surveillance, temperature sensors, or pressure sensors. These detectors 440 can detect changes in the external environment in real time and control the retraction and extension of antenna assembly 400 based on these environmental changes. Furthermore, detector 440 may also be a combination of vibration sensors, video surveillance, temperature sensors, and pressure sensors, enabling faster and more accurate measurement of changes in the external environment.

[0081] On this basis, if Figure 9 As shown, the upper and lower sides of the antenna rack 410 are respectively provided with mounting grooves 411, and the mounting grooves 411 are recessed into the interior of the antenna rack 410. The embedded single antenna 460 is basically flush with the upper and lower sides of the antenna rack 410, so that the single antenna 460 can be more safely set on the antenna rack 410.

[0082] In some embodiments of the present invention, the mounting groove 411 can be a whole groove, and several single antennas 460 are embedded in the mounting groove 411 in a matrix array. In this way, the processing difficulty of the antenna rack 410 is small, but the arrangement of all the single antennas 460 in one mounting groove 411 is not conducive to the installation and maintenance of the single antennas 460.

[0083] In some other embodiments of the present invention, the mounting slot 411 may be a plurality of mounting slots 411 arranged in a matrix array, and each mounting slot 411 is installed with a single antenna 460. Such an arrangement facilitates the installation and protection of the single antenna 460, and each single antenna 460 can be safely protected, but the antenna rack 410 is more difficult to process.

[0084] The antenna frame 410 is further provided with a wiring channel 480 at the symmetrical center of the antenna frame 410. The wiring channel 480 is used for wiring the single antenna 460. Figure 9 As shown, a buffer structure 450 is provided between each antenna 460 and the mounting slot 411. Each antenna 460 is connected to a buffer structure 450, and the buffer structure 450 is fixedly connected to the bottom wall of the mounting slot 411. When an external force is applied to the antenna 460, the buffer structure 450 buffers and eliminates the external force, thereby reducing the impact and damage to the antenna 460 without affecting the use of the antenna 460.

[0085] In some embodiments of the present invention, the buffer structure 450 can be a rubber buffer column or an elastic member, which can buffer and eliminate the external force exerted on the single antenna 460 through the deformation of the rubber buffer column and the elastic member, thereby reducing the hard damage to the single antenna 460. The buffer structure 450 can also be a combination of a rubber buffer column and an elastic member to further protect the single antenna 460. The rubber buffer column bears a part of the external force exerted on the single antenna 460 and then deforms to eliminate the external force. After the other part of the external force contacts the elastic member, the elastic member eliminates the external force by shaking and contracting, resulting in a better buffering effect. Of course, the buffer structure 450 can also be other buffer structures 450 that meet the requirements and have certain deformation and buffering capabilities. At the same time, the outer surface of the buffer structure 450 is also provided with an anti-corrosion coating to slow down the corrosion of the buffer structure 450 in rainy and snowy weather, thereby increasing its service life.

[0086] In some embodiments of the present invention, the antenna mount 410 may be a curved plate-like structure. Because a curved structure occupies a relatively short length, configuring the antenna mount 410 as a curved structure increases the length of the curved plate, thereby allowing for the carriage of more individual antennas 460. Furthermore, since the curved structure has a relatively small degree of bending, it does not affect the signal transmission of each individual antenna 460. Furthermore, the curved structure facilitates entry and exit from the housing 110.

[0087] Furthermore, when the antenna frame 410 is an arc-shaped structure, that is, the antenna assembly 400 is also an arc-shaped structure, at this time, after the antenna assembly 400 extends out of the retractable hole 130, the antenna assembly 400 extends to the left or right, such as Figure 1 As shown, multiple antenna assemblies 400 are arranged along the second straight line direction, the antenna assembly 400 located on the left side of the first connecting plate 310 extends to the left, and the antenna assembly 400 located on the right side of the first connecting plate 310 extends to the right.

[0088] It should be noted that the single antenna 460 and the communication device 150 are connected through a signal line, and the signal line is centrally collected in the wiring channel 480. In the process of retracting and extending the antenna assembly 400, there will be no problems with the line problem causing the antenna assembly 400 to be retracted and extended, resulting in an inability to retract or extend.

[0089] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0090] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
