Description

Technical Field

[0001] This utility model belongs to the technical field of emergency broadcasting vehicle equipment, specifically, it relates to a hydraulic self-balancing leveling support leg for an emergency broadcasting vehicle. Background Technology

[0002] When an emergency broadcasting vehicle is performing its mission, the roof-mounted speaker is a crucial sound transmission device. Its installation stability and height adjustment accuracy directly affect the broadcast coverage and transmission effect. When operating in complex terrain, uneven ground can cause the broadcasting vehicle to tilt, which in turn causes the roof-mounted speaker to deviate at an angle, resulting in problems such as deviation in sound propagation direction and uneven coverage area. Therefore, self-balancing hydraulic outriggers are used.

[0003] The radio speaker located on the roof uses self-balancing leveling legs. Due to its large size, it will occupy a significant amount of space on the roof after adjustment, thus affecting the storage space for other equipment.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the technical problem that roof-mounted loudspeakers, due to their large size, occupy significant roof space after adjustment, thus affecting the storage space for other equipment, the basic concept of this utility model is as follows:

[0006] An emergency broadcast relay vehicle hydraulic self-balancing leveling outrigger includes a roof and a bracket connected to the top surface of the roof. An adjustment and storage mechanism and a moving mechanism are installed on the roof and the bracket.

[0007] The adjustment and storage mechanism includes a speaker mounted on a bracket, and a storage frame is provided below the speaker for storing the support and adjustment components below.

[0008] The moving mechanism includes a limiting slide groove located below the horn, with a limiting slider slidably disposed on the inner wall of the limiting slide groove, and the top surface of the storage frame connected to the lower surface of the limiting slider.

[0009] In a preferred embodiment of this utility model, the adjustable storage mechanism includes a damping shaft rotatably mounted on a bracket, a horn connected to the outer wall of the damping shaft, a motor mounted on the outer wall of the storage frame, a bidirectional lead screw connected to the output end of the motor, a threaded block threaded to the outer wall of the bidirectional lead screw, a storage groove inside the storage frame, an extension support block movably mounted inside the storage groove, and one side of the outer wall of the extension support block connected to the outer wall of one end of the threaded block.

[0010] In a preferred embodiment of this utility model, the moving mechanism includes an electric telescopic rod installed on the roof of the vehicle, a connecting plate connected to the output end of the electric telescopic rod, and the outer wall of the connecting plate away from the electric telescopic rod connected to the bottom end of the storage frame.

[0011] In a preferred embodiment of the present invention, the bottom end of the extension support block is provided with a concave hole, a hydraulic cylinder is installed at the top of the inner wall of the concave hole, a rotating hole is provided on the outer wall of the output end of the hydraulic cylinder, a rotating shaft is rotatably provided on the inner wall of the rotating hole, and support legs are connected to the outer walls of both ends of the rotating shaft.

[0012] In a preferred embodiment of this utility model, the inner wall of the storage groove is provided with a movable groove, and the outer wall of the threaded block is movably disposed on the inner wall of the movable groove, and the two are fitted together appropriately.

[0013] In a preferred embodiment of this utility model, there are two hydraulic cylinders, which are distributed symmetrically inside the storage frame, and the support legs are made of rubber.

[0014] In a preferred embodiment of this utility model, the limiting slider is configured as a "T" shape, and the outer wall of the limiting slider is fitted to the inner wall of the limiting groove.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention utilizes a motor to drive a bidirectional lead screw, which in turn moves the threaded block closer to the center. This causes the extended support blocks on both sides to gradually retract and move into the storage slot. Then, the hydraulic cylinder output end is activated to retract, thereby retracting the support legs. This reduces the space occupied, making it easier to store other equipment.

[0017] This invention uses an electric telescopic rod to move a connecting plate, which in turn moves a storage frame along the inner wall of a limiting slide groove via a limiting slider. This allows the entire storage frame to be moved to the leftmost end below the speaker, thereby connecting the space below the speaker, increasing the space available for storing other equipment.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 5 As shown, an emergency broadcast relay vehicle hydraulic self-balancing leveling outrigger includes a roof 1 and a bracket 2 connected to the top surface of the roof 1. An adjustment and storage mechanism 31 and a moving mechanism 32 are installed on the roof 1 and the bracket 2. The adjustment and storage mechanism 31 includes a horn 312 installed on the bracket 2. A storage frame 313 is provided below the horn 312. The storage frame 313 is used to store the support and adjustment components below. The moving mechanism 32 includes a limiting groove 321 opened below the horn 312. A limiting slider 322 is slidably provided on the inner wall of the limiting groove 321. The top surface of the storage frame 313 is connected to the lower end surface of the limiting slider 322.

[0028] Furthermore, the adjustment and storage mechanism 31 includes a damping shaft 311 rotatably mounted on the bracket 2, a horn 312 connected to the outer wall of the damping shaft 311, a motor 314 mounted on the outer wall of the storage frame 313, a bidirectional lead screw 315 connected to the output end of the motor 314, a threaded block 316 threadedly connected to the outer wall of the bidirectional lead screw 315, a storage groove 317 opened inside the storage frame 313, an extension support block 318 movably mounted inside the storage groove 317, and one side of the outer wall of the extension support block 318 connected to one end of the outer wall of the threaded block 316.

[0029] Furthermore, the bottom end of the extension support block 318 is provided with a concave hole, and a hydraulic cylinder 319 is installed at the top of the inner wall of the concave hole. A rotating hole is provided on the outer wall of the output end of the hydraulic cylinder 319, and a rotating shaft 3110 is rotatably provided on the inner wall of the rotating hole. Support legs 3111 are connected to the outer walls of both ends of the rotating shaft 3110.

[0030] Furthermore, the inner wall of the storage slot 317 is provided with a movable slot, and the outer wall of the threaded block 316 is movably set in the inner wall of the movable slot, and the two fit together properly. There are two hydraulic cylinders 319, which are distributed in a symmetrical structure inside the storage frame 313. The support legs 3111 are made of rubber, which can improve the stability of the threaded block 316 during the movement of the movable slot. The hydraulic cylinders 319 on the left and right sides are connected to an external controller (not shown in the figure), so that the controller controls the hydraulic cylinders 319 on both sides to perform self-balancing adjustment support, ensuring that the horn 312 can be in a horizontal state.

[0031] The moving mechanism 32 includes an electric telescopic rod 323 installed on the roof 1. A connecting plate 324 is connected to the output end of the electric telescopic rod 323. The outer wall of the connecting plate 324 away from the electric telescopic rod 323 is connected to the bottom end of the storage frame 313.

[0032] Furthermore, the limiting slider 322 is set in a "T" shape, and the outer wall of the limiting slider 322 fits snugly against the inner wall of the limiting groove 321. The limiting slider 322 can be limited and slid by the set "T" shape.

[0033] The implementation principle of the hydraulic self-balancing leveling outriggers of the emergency broadcast relay vehicle in this embodiment is as follows: When the vehicle is parked on uneven ground, the angle of the horn 312 will change. At this time, the motor 314 can be started, and its output end will drive the bidirectional lead screw 315 to rotate. The rotation of the bidirectional lead screw 315 will drive the threaded block 316 to move to the left and right. As the threaded block 316 moves, it will drive the extension support blocks 318 on both sides to move to the left and right, thereby extending out of the interior of the storage groove 317. At the same time as the extension support blocks 318 move, it will drive the hydraulic cylinder 319 and the support leg 3111 below to move, thereby driving the extension support blocks 318 and the hydraulic cylinder 319 on both sides to extend. After exiting the inner wall of the storage slot 317, the external controller can be turned on to activate the hydraulic cylinders 319 on both sides. At this time, the hydraulic cylinders 319 will self-balance by adjusting the tilt angle of the horn 312. The angle adjustment can be completed by rotating the damping shaft 311 and the bracket 2. While the horn 312 is adjusting its angle, it will drive the hinge seat 325 and the connecting plate 324 to rotate. After the adjustment is completed, the output end of the motor 314 can be reversed, and the output end of the hydraulic cylinder 319 will retract. At this time, the extension support block 318 can drive the hydraulic cylinder 319 to be stored inside the storage slot 317, thus reducing the space occupied by the horn 312 and the support structure below, thereby facilitating the storage of other equipment.

[0034] Then, the electric telescopic rod 323 is activated, and its output end will drive the connecting plate 324 to retract to one side. As the connecting plate 324 moves, the storage frame 313 will move. At this time, the storage frame 313 will move through the sliding connection between the limiting slider 322 and the limiting groove 321 until the storage frame 313 is moved to the lower left end of the speaker 312. This will connect the space below the speaker 312, thereby increasing the space area below and making it easier to store other equipment.
