Description

Technical Field

[0001] This invention relates to the field of servo motor technology, and more specifically, to a servo motor control signal receiving mechanism based on telemetry technology. Background Technology

[0002] Electric motors are common components in modern drive systems, providing power to various workpieces or processing procedures. There are many types of motors, and servo motors are one of them. Servo motors have advantages such as convenient speed adjustment and accurate position, making them widely used in various industries. They are especially prevalent in processes requiring back-and-forth rotation. Servo motors can convert voltage signals into torque and speed signals to drive the actuator. The voltage signal reception of servo motors can be done in two ways: through wired sensors connected to the outside, or through telemetry structures.

[0003] Telemetry servo motors are a mature type of servo motor on the market. The telemetry mechanism enables remote operation and control. The telemetry mechanism mainly consists of transmitting and receiving equipment. In some applications, additional monitoring equipment is installed to check if the servo motor is functioning correctly. However, current receiving equipment on the market still has the following problems:

[0004] Currently, most receivers on the market are integrated with servo motors to ensure control. However, this close proximity makes disassembly and maintenance of the receiver very difficult, increasing the workload of staff. It is also difficult to operate in places with poor signal. Furthermore, cleaning the receiver surface is troublesome once it gets dusty. In addition, the servo motor generates heat when it operates, and the receiver generates heat in the same environment. The two types of heat interact and affect the lifespan of both the servo motor and the receiver.

[0005] To address the aforementioned issues, an innovative design was developed based on the existing receiving mechanism. Summary of the Invention

[0016] Receiver;

[0017] An upper card block, which is located above the receiver, is sized to match the receiver so as to card and be above the receiver;

[0018] An extension rod is located above the upper locking block, and the extension rod is connected to the upper locking block by a rotatable connection;

[0019] A lower card block, located at the lower part of the receiver, the size and shape of which match the size of the receiver, to card the lower part of the receiver;

[0020] A sliding block is located on the lower side of the lower locking block. The sliding block is connected to the lower locking block by a rotational connection. The two sliding blocks are symmetrically distributed on both sides of the lower locking block.

[0021] A storage block is located below the sliding block. The upper end of the storage block is slidably connected to the sliding block, and the lower end of the storage block is rotatably connected to the protective shell.

[0022] The limiting blocks are located on both sides of the receiver, and the limiting blocks are fixedly connected to the upper and lower locking blocks.

[0023] Preferably, one side of the extension rod is connected to an opening and closing door, and one end of the opening and closing door is symmetrically distributed with fixing rods. The opening and closing door is connected to the protective shell by a rotatable connection, and the fixing rod is connected to the opening and closing door by a rotatable connection.

[0024] Preferably, a lifting block is provided above the connecting wire, and a connecting spring is connected above the lifting block. The lifting block and the protective shell together form a spring reset structure through the connecting spring.

[0025] Preferably, the other end of the connecting wire passes through the linkage block and connects to the receiver.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. This invention provides an adjustment mechanism inside the protective shell to store the receiver and drive motor separately. It also has an opening and closing door that automatically moves the receiver when the door is opened, allowing the receiver to extend out of the protective shell. This facilitates the maintenance and inspection of the receiver, improves work efficiency, and ensures the smooth progress of subsequent work. When disassembling, the receiver can be detached from the upper clip to complete the disassembly.

[0035] 2. This invention separates the receiver from the drive motor by setting an insulating plate and a heat dissipation mechanism inside the protective shell, so that the heat between them will not affect each other. The drive rod drives the first and second fan blades to rotate in opposite directions, which speeds up the air flow inside the protective shell. This allows the first and second fan blades to dissipate heat from the drive motor and the receiver respectively, which helps to improve heat dissipation efficiency and extend the service life of the drive motor and the receiver.

[0036] 3. The present invention provides a linkage block and a lifting block on both sides of the connecting wire, and a connecting spring is provided above the lifting block. This ensures that the connecting wire is always in a tight state and also relaxes when the receiver is adjusted. This prevents the connecting wire from getting tangled or knotted as the receiver moves, ensuring that the receiver adjustment is carried out and facilitating the automated adjustment and fixing of the connecting wire.

Detailed Implementation

[0047] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0048] like Figures 1 to 7 As shown, the present invention provides a receiving mechanism for servo motor control signals based on telemetry technology, comprising:

[0049] The protective shell 1 has a drive motor 4 inside, and a drive rod 5 is connected to one side of the drive motor 4. Heat dissipation mechanisms 2 are provided on both sides of the drive rod 5.

[0050] An isolation plate 10, located on the other side of the drive motor 4, divides the protective housing 1 into a motor cavity and an adjustment cavity. The drive motor 4 is disposed in the motor cavity, and an adjustment mechanism 3 is disposed in the adjustment cavity. A connecting wire 9 is disposed in the central through hole on the isolation plate 10. One end of the connecting wire 9 is electrically connected to the drive motor, and the other end is electrically connected to the adjustment mechanism 3.

[0051] In this embodiment of the invention, the heat dissipation mechanism 2 includes,

[0052] The connecting belt 201 is located on both sides of the drive rod 5, and one end of the connecting belt 201 is connected to the drive rod 5 through a pulley;

[0053] The rotating rod 202 is located on both sides of the drive motor 4. The rotating rod 202 is connected to the drive rod 5 by the connecting belt 201 to form an integrated rotation. The rotating rod 202 is connected to the protective shell 1 by rotation.

[0054] The first fan blade 203 is located on the rotating rod 202. The first fan blade 203 is symmetrically distributed at both ends of the rotating rod 202. When the connecting belt 201 drives the rotating rod 202 to rotate, it drives the first fan blade 203 to rotate, thereby enabling the drive motor 4 to dissipate heat.

[0055] One end of the rotating rod 202 extending into the adjustment cavity is connected to a first gear 204. A second gear 206 meshing with the first gear 204 is connected to one side of the first gear 204. An auxiliary rod 205 is connected to the center of the second gear 206, and a second fan blade 207 is connected to the free end of the auxiliary rod 205. The rotating rod 202 is connected to the first gear 204 by a heat fusion connection, the second gear 206 is connected to the auxiliary rod 205 by a heat fusion connection, and the auxiliary rod 205 is connected to the isolation plate 10 by a rotatable connection. The auxiliary rod 205 and the second fan blade 207 rotate as a whole. Through the cooperation of the rotating rod 202 and the auxiliary rod 205, the second fan blade 207 is driven to rotate, so that the second fan blade 207 can dissipate heat from the receiver 301 and prevent the temperature around the receiver 301 from becoming too high.

[0056] The regulating mechanism 3 also includes,

[0057] Receiver 301;

[0058] Upper card block 302 is located above receiver 301, and the size of upper card block 302 matches the size of receiver 301, so as to card and above receiver 301;

[0059] The extension rod 303 is located above the upper locking block 302, and the extension rod 303 is connected to the upper locking block 302 by a rotatable connection.

[0060] The lower card block 304 is located at the lower part of the receiver 301, and the size and shape of the lower card block 304 match the size of the receiver 301.

[0061] The sliding block 305 is located on the lower side of the lower locking block 304. The sliding block 305 and the lower locking block 304 are connected by rotation. The two sliding blocks 305 are symmetrically distributed on both sides of the lower locking block 304.

[0062] Storage block 306 is located below sliding block 305. The upper end of storage block 306 is slidably connected to sliding block 305, and the lower end of storage block 306 is rotatably connected to protective shell 1.

[0063] Limiting blocks 309 are located on both sides of receiver 301. Limiting blocks 309 are fixedly connected to upper locking blocks 302 and lower locking blocks 304. Through the cooperation of upper locking blocks 302 and lower locking blocks 304, receiver 301 is fixedly limited, thereby driving receiver 301 to move out of protective housing 1, improving maintenance efficiency.

[0064] One side of the extension rod 303 is connected to the opening and closing door 307. Fixed rods 308 are symmetrically distributed at one end of the opening and closing door 307. The opening and closing door 307 is connected to the protective shell 1 by rotation. The fixed rods 308 are also connected to the opening and closing door 307 by rotation. The extension rod 303 is connected to the opening and closing door 307 so that the opening and closing door 307 extends directly out of the protective shell 1 when it is opened, thereby improving maintenance efficiency.

[0065] A lifting block 6 is provided above the connecting wire 9, and a connecting spring 7 is connected above the lifting block 6. The lifting block 6 and the protective shell 1 form a spring reset structure through the connecting spring 7. The lifting block 6 limits the connecting wire 9 to prevent it from shaking and getting tangled during use.

[0066] The other end of the connecting wire 9 passes through the linkage block 8 and connects to the receiver 301. A circular groove is opened in the center of the linkage block 8. The linkage block 8 and the protective shell 1 are installed as an integral part. The linkage block 8 performs secondary positioning to ensure the fixation of the connecting wire 9.

[0067] The size of the isolation plate 10 is the same as the size of the inner wall of the protective shell 1. The isolation plate 10 is fixedly connected to the protective shell 1, and the isolation plate 10 is rotatably connected to the rotating rod 202. The isolation plate 10 separates the space inside the protective shell 1, ensuring that the receiver 301 and the drive motor 4 do not interfere with each other.

[0068] The working principle of the servo motor control signal receiving mechanism based on telemetry technology provided by this invention is as follows:

[0069] like Figures 1 to 7As shown, firstly, the receiver 301 is remotely controlled by the transmitting device to transmit and receive signals. Then, the receiver 301 transmits the signal to the drive motor 4 through the connecting wire 9, causing the drive motor 4 to drive the drive rod 5 to rotate and start working. At this time, when the drive rod 5 rotates, it drives the rotating rods 202 on both sides to rotate through the two connecting belts 201 respectively. When the rotating rods 202 rotate, they drive the first fan blade 203 and the first gear 204 to rotate. The first fan blade 203 accelerates the air circulation around the drive motor 4 to dissipate heat. The first gear 204 meshes with the second gear 206, so the second gear 206 and the auxiliary rod 205 in the center rotate together, bringing the second fan blade 207 into working state as well, to dissipate heat for the receiver 301 and ensure the use of the receiver 301. Moreover, the first fan blade 203 and the second fan blade 207 rotate in opposite directions, so they will not affect each other and can distribute the heat dissipation work for the drive motor 4 and the receiver 301.

[0070] like Figures 1 to 5 As shown, when maintenance is required or signal reception efficiency needs to be improved, the fixing rod 308 is rotated to both sides, releasing the fixing and limiting of the opening and closing door 307. Then, the opening and closing door 307 is lifted upwards. During the upward rotation of the opening and closing door 307, the extension rod 303 moves, thereby pulling the upper locking block 302. The upper locking block 302 pulls the receiver 301 and the lower locking block 304 together, extending towards the outside of the protective shell 1. Because the two sides of the extension rod 303 rotate with the upper locking block 302 and the opening and closing door 307 respectively, it can be adjusted at any angle. The lower locking block 304 and the sliding block 305 are also rotatably connected, and the sliding block 305 is also telescopically connected to the storage block 306. The structure allows for maintenance when the receiver 301 is extended. To disassemble the receiver 301, press down the lower latch 304 and pull the upper latch 302 to separate it from the receiver 301, then pull out the receiver 301. Similarly, when the receiver 301 is pulled, the connecting wire 9 begins to move outward and tighten, thereby lifting the lifting block 6. When the receiver 301 returns to its original position, the connecting wire 9 begins to loosen. At this time, the connecting spring 7 drives the lifting block 6 to return to its original position, ensuring that the connecting wire 9 remains taut and does not become knotted. This is the entire working process of the device. Any content not described in detail in this specification is existing technology known to those skilled in the art.

[0071] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
