Description

Technical Field:

[0001] The present invention belongs to the technical field of hanging devices, and particularly refers to a structure of a hanging drive component. Background Art:

[0002] Currently, the shells of hanging drive components are all nearly closed structures. Due to the difficulty of heat dissipation in nearly closed structures, they can only meet the occasions with low speed or low ambient temperature, and have great limitations. If slots are opened at the bottom to increase the heat dissipation space, in an indoor environment with poor air circulation, the heat dissipation improvement effect is poor. In addition, it will cause dust and other foreign matters to enter, covering the control board (PCB board), reducing the heat dissipation capacity and increasing the failure rate of the control board. Therefore, this structure can no longer meet the requirements for the subsequent development of new functions, speed increase and reliability of our products. Summary of the Invention:

The nest is processed and formed by metal Q235B. The main line gear is integrally formed by polyoxymethylene injection molding on the outer circumference of the nest, and reinforcing ribs are respectively distributed in a circumferential manner on the upper and lower sides of the main line gear.

Detailed Embodiments:

[0026] The present invention will be further described below with specific embodiments. Refer to Figure 1 —5:

[0027] A structure of a hanging drive component includes a housing 2 installed on a guide rail 1. The housing 2 includes a control housing 2a erected above the guide rail 1. A PCB board 3 is provided in the control housing 2a. A heat dissipation bottom plate 4 is provided in the control housing 2a below the PCB board 3. A notch 5 is opened at the bottom of the control housing 2a. The heat dissipation bottom plate 4 extends downward to form a boss 6 extending into the notch 5. A non-metallic heat conducting sheet 7 is fixed to the bottom of the boss 6, and the lower surface of the non-metallic heat conducting sheet 7 abuts against the guide rail 1.

[0028] As Figure 1-4 shown, in the present invention, a notch 5 is opened at the bottom of the control housing 2a, a boss 6 extending into the notch 5 is provided on the heat dissipation bottom plate 4, and a non-metallic heat conducting sheet 7 abutting against the guide rail 1 is provided below the boss 6. Heat is transferred to the non-metallic heat conducting sheet 7 through the boss 6 and the non-metallic heat conducting sheet 7, greatly improving heat dissipation. At the same time, it will not affect the installation of the heat dissipation bottom plate 4 and the components on the guide rail 1, solving the great dependence of the existing structure on the environment. In addition, the boss 6 is arranged in the notch 5, and the guide rail 1 is arranged below the notch 5, which can effectively reduce dust and foreign objects from entering the control housing 2a through the notch 5. Therefore, the PCB board has good heat dissipation ability and low failure rate, can meet the occasions with high speed and relatively high ambient temperature, and has wide applicability. At the same time, by contacting the guide rail 1 with the non-metallic heat conducting sheet 7 to transfer heat, the static electricity problem caused by metal contact can be effectively avoided.

[0029] Furthermore, the non-metallic heat conducting sheet 7 can be bonded to the heat dissipation bottom plate 4 by back glue, or can be clamped on the heat dissipation bottom plate 4 through a buckle provided on the non-metallic heat conducting sheet 7 and a groove provided on the heat dissipation bottom plate 4. In this embodiment, the non-metallic heat conducting sheet 7 can be bonded to the heat dissipation bottom plate 4 by back glue.

[0030] For better heat dissipation effect and better dust prevention effect, two or more bosses 6 are provided at intervals. Connecting rib strips 8 are provided between adjacent two bosses 6, and both ends of the connecting rib strips 8 are respectively connected to the side walls of the notch 5. The connecting rib strips 8 are basically attached to the bottom surface of the heat dissipation bottom plate 4, which can effectively reduce dust and foreign objects from entering the control housing through the notch.

[0031] Preferably, the non-metallic heat conducting sheet 7 is a heat conducting silica gel sheet, a nylon gasket or a heat conducting rubber sheet. In this embodiment, the non-metallic heat conducting sheet 7 is a heat conducting silica gel sheet, which has good heat conducting performance, excellent softness and elasticity, and can better contact the guide rail 1, with good heat conducting effect.

[0032] In order to further improve the dustproof effect, a port slot 9 is opened on the side of the control housing 2 a , and a connection terminal 10 is provided on the PCB board 3 , and the connection terminal 10 extends into the port slot 9 .

[0033] Furthermore, more than two wiring terminals 10 are provided. In the present embodiment, four wiring terminals 10 are provided, which are respectively used for CAN communication, motor reversal, motor start and stop, and motor status, and two port slots 9 are provided. The wiring terminals 10 for CAN communication and motor reversal are provided in the same port slot 9, and the wiring terminals 10 for motor start and stop and motor status are provided in the same port slot 9.

[0034] The existing long slot inner wiring structure is usually adopted. Since it needs to meet the needs of different types of wires, its slot size is large, and dust and other foreign objects are easy to enter the PCB board 3, which reduces the heat dissipation capacity and increases the failure rate. The inner wiring needs to open the control board cover 22 every time it connects and disconnects the wires, which increases the risk of dust and other foreign objects entering the PCB board 3, thereby causing PCB board failure and heating problems. Compared with the existing long slot inner wiring structure, the present invention is changed to a port slot 9 and a terminal 10 extending into the port slot 9, which effectively reduces dust and foreign objects from entering the control housing 2a, thereby reducing PCB board failure and heating. At the same time, there is no need to open the control board cover 22 during wiring and disassembly, which effectively improves the dustproof effect and the convenience of disassembly and assembly.

[0035] The installation structure of the housing 2 is as follows: Figure 1-3 As shown in Figures 5 and 6, the housing 2 further includes a driving housing 2b for installing a driving assembly, the driving housing 2b is arranged on the side of the guide rail 1, a dovetail block 11 for hooking the guide rail 1 is arranged on the driving housing 2b, a nut 12 is embedded in the dovetail block 11, the rod of the bolt 13 passes through the mounting plate 14 of the driving housing 2b and is screwed to the nut 12, and the guide rail 1 is limited between the mounting plate 14 and the dovetail block 11. The structure is simple, the installation is convenient, and the installation is firm and reliable.

The output shaft 18 of the speed reducer 16 passes through the horizontal partition plate 2b3 to connect the main line gear 17. A nest 19 sleeved outside the output shaft 18 is provided between the main line gear 17 and the output shaft 18. A plurality of convex strips are evenly distributed on the outer circumference of the nest 19. The nest 19 is processed and formed from metal Q235B. The main line gear 17 is integrally injection-molded from polyoxymethylene on the outer circumference of the nest 19, and reinforcing ribs are respectively circumferentially distributed on the upper and lower sides of the main line gear 17, greatly avoiding deformation problems during the manufacturing process.
