Description

TECHNICAL FIELD

[0001] The present application relates to vehicle turnover platform adjustment technology, in particular to a self-locking electric remote control turnover mechanism. BACKGROUND

[0002] In the field of special vehicle operation, such as fire trucks, engineering rescue vehicles, police patrol vehicles, etc., the pitch angle control of various external devices is a key function to achieve efficient night operation and emergency response. Such devices not only have large size and weight, but also have extremely harsh working environment: the continuous operation of the vehicle engine brings severe vibration; the vehicle generates jolt and impact when moving or positioning on uneven road surface; outdoor operation often encounters wind load in uncertain direction. At present, the turnover mechanism applied in such scenes is mostly driven by hydraulic or electric power. The electric driving scheme has more advantages due to its fast response and high control precision, but it often lacks effective self-locking function when it stops running, which leads to position deviation under the action of vibration, external force or self-weight, affecting the use effect and stability. SUMMARY

[0003] The purpose of the present application is to provide an electric remote control turnover mechanism with self-locking function to solve the problem of poor self-locking performance of the existing turnover mechanism.

[0004] In order to achieve the above purpose, the present application provides the following technical scheme: an electric remote control turnover mechanism with self-locking function, comprising a driving assembly, the driving assembly comprising a driving member, one side of the driving member being fixedly installed with a driving box, a turnover member being rotatably arranged on the side wall of the driving box;

[0005] A worm gear is rotatably arranged in the driving box, the output end of the driving member is fixedly installed with a worm gear rotatably arranged around its own axis, one end of the worm gear extends into the driving box, the worm gear and the worm gear are meshingly arranged, and the two ends of the worm gear are fixedly installed with a rotating shaft.

[0006] The turnover member comprises a turnover rod fixedly installed on the side wall of the driving box, and the turnover rod is fixedly connected with the rotating shaft.

[0007] Further, the lower surface of the driving box is fixedly installed with a supporting rod, and the lower surface of the supporting rod is fixedly installed with a base.

[0008] Further, the turnover member is provided with two groups, which are distributed on both sides of the turnover box, and the two sides of the worm gear are fixedly installed with a turnover rod.

[0009] Further, the driving member is provided with two groups, and the two ends of the turnover rod extend into the driving box and are fixedly connected with the internal worm gear.

[0010] Compared with the prior art, the electric remote control flipping mechanism with self-locking function provided by the present invention adopts a transmission pair composed of worm and worm wheel, and utilizes its inherent reverse self-locking characteristics to enable the flipping mechanism to achieve reliable position locking without additional braking device when the drive stops, effectively overcoming the problem of angle deviation under vibration, load and external force impact; at the same time, the structure has smooth transmission, low noise and compact structure.

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example 1: As Figure 1 - Figure 2 As shown, it includes a drive assembly, which includes a drive component 1, which can be a stepper motor, etc. A drive box 2 is fixedly installed on one side of the drive component 1. The drive box 2 is used to house and protect the internal transmission mechanism (such as worm gear 3 and worm 4), and also serves as structural support and dust protection. A flipping component is rotatably provided on the side wall of the drive box 2.

[0020] A worm gear 3 is rotatably installed inside the drive box 2. A worm 4 is fixedly installed at the output end of the drive component 1 and rotates around its own axis. One end of the worm 4 extends into the drive box 2 and meshes with the worm gear 3. A rotating shaft 6 is fixedly installed at both ends of the worm gear 3. The worm gear 3 meshes with the worm 4, converting the rotational motion of the worm 4 into the rotation of the worm gear 3 itself, thereby realizing the transmission of motion and the reduction and torque increase.

[0021] The flipping component includes a flipping rod 5 fixedly installed on the side wall of the drive box 2, which swings under the drive of the worm gear 3, thereby adjusting the pitch angle of the flipping rod 5. The flipping rod 5 is fixedly connected to the rotating shaft 6.

[0022] Furthermore, a support rod 7 is fixedly installed on the lower surface of the drive box 2, and a base 8 is fixedly installed on the lower surface of the support rod 7. The base 8 is located at the bottom of the equipment, providing stable support and ensuring that the equipment does not move or tip over during operation.

[0023] Working principle: When the user starts the drive unit 1, the drive unit 1 outputs rotational power, and the worm 4 begins to rotate under the drive unit 1. The worm wheel 3, which meshes with the worm 4, converts the rotational motion into its own low-speed rotation around the axis. The rotation of the worm wheel 3 drives the flipping rod 5 connected to it to move. Due to the self-locking characteristics of the worm wheel 3 and worm 4 mechanism, the flipping rod 5 can be stably maintained after being adjusted to the required angle and will not return to its original position due to external force. The entire transmission mechanism is sealed in the drive box 2, and the support rod 7 and the base 8 provide stable support for the system.

[0024] Example 2: Figure 2 - Figure 3 As shown

[0025] This embodiment is basically the same as the previous embodiment, except that there are two sets of flipping components, distributed on both sides of the flipping box. Both sides of the worm gear 3 are fixedly installed with flipping rods 5. With this setting, only one set of driving components 1 is needed to drive the flipping rods 5 on both sides to flip, and the angle of the flipping rods 5 on both sides can be adjusted and self-locked.

[0026] Working principle: The operation is the same as in Embodiment 1. However, in this embodiment, the flipping parts are set into two sets and distributed on both sides of the flipping box. The flipping rods 5 are fixedly installed on both sides of the worm gear 3. The flipping rods 5 extend out of the drive box 2. With this setting, only one set of drive parts 1 is needed to drive the flipping rods 5 on both sides to flip, and the angle of the flipping rods 5 on both sides can be adjusted and self-locked.

[0027] Example 3: Figure 4 As shown

[0028] The embodiment is basically same as the previous embodiment, the difference is that the driving member 1 is provided with two groups, the both ends of the turnover rod 5 are inserted into the driving box 2 and are fixedly connected with the internal worm wheel 3, two groups of completely symmetrical driving mechanisms (driving member 1, worm 4, worm wheel 3) are arranged at the both ends of the turnover rod 5, the driving members 1 on the both sides are synchronously driven, the power is symmetrically transmitted on the both sides synchronously. This makes the turnover rod 5 like a beam which is pushed at the both ends simultaneously when being stressed, eliminates the torsional bending moment, minimizes the running resistance, the action is more stable and smooth, the jamming phenomenon is fundamentally avoided, and the wear of the parts on the both sides is uniform, the service life is consistent.

[0029] Further, the two groups of driving members 1 mean two sets of worm wheel 3 and worm 4 self-locking mechanisms. They jointly "lock" the turnover rod 5 from the both ends, form the stable support of two points determining a straight line. This makes the carrying capacity of the whole platform be doubled, can support larger and heavier equipment. At the same time, the double self-locking greatly enhances the stability of anti-vibration and angle retention, ensures that the turnover rod 5 has no possibility of self-loosening after being adjusted to the specified angle.

[0030] Working principle: the embodiment sets the driving member 1 as two groups, and fixes the both ends of the turnover rod 5 with the worm wheel 3, which solves the inherent problems of uneven stress, easy jamming and poor stability of single-side driving through the core idea of symmetrical driving and double self-locking, thereby bringing qualitative improvement in running stability, carrying capacity, adjustment precision and system reliability, and is an optimization and improvement with innovation and practicality.

[0031] The above only describes certain exemplary embodiments of the present application in a descriptive manner, without doubt, for ordinary skilled in the art, the described embodiments can be modified in various ways without departing from the spirit and scope of the present application. Therefore, the above figures and description are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
