Description

Technical Field

[0001] This utility model belongs to the field of steering motors, specifically, it relates to a steering motor with a sealing function. Background Technology

[0002] Existing technical solutions typically involve designing a sealant reservoir on an integrated connector. Sealant is injected into the reservoir, and then the electronic control back cover is pressed onto the sealant. The sealant is then compressed to fill the gap between the two components, achieving a seal. However, this sealing structure design has certain flaws. It only designs the sealant reservoir and the pressing surface. This structure merely compresses the sealant in the reservoir to fill the gap between the two components, forming a sealed structure after the sealant solidifies. This structure cannot guide the flow of the sealant; the sealant cannot be effectively compressed and flow to the intended filling area, leading to seal failure or poor protection. Furthermore, existing technical solutions only form a single sealant protection structure, resulting in inadequate protection. Once damaged, the sealant's protective function is lost. There are also design flaws regarding structural reliability; under extreme operating conditions, the reliability of the protective function decreases, posing a risk of protective failure.

[0003] A search revealed that Chinese patent CN221908139U, published on October 29, 2024, discloses a curing structure for motor adhesive. The structure includes a curing machine, a controller fixedly connected to the surface of the curing machine, a curing head slidably connected to the surface of the curing machine, a placement platform slidably connected to the surface of the curing machine, and a stabilizing device on the surface of the curing machine. The stabilizing device includes two rotating rods, with clamping plates rotatably connected to the arc surfaces of the two rotating rods. Stabilizing grooves are formed on the surfaces of the clamping plates. A rotating rod is rotatably connected to the surface of the curing machine, and a stabilizing block is fixedly connected to the arc surface of the rotating rod. This device cannot achieve double-layer sealing and has a complex structure. Utility Model Content

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.

[0023] like Figure 1 and Figure 2 As shown, a steering motor with a sealing function includes a rear cover housing 1 and a connector 2. The connector 2 is disposed on the rear cover housing 1, and a sealing structure 3 is provided between the connector 2 and the rear cover housing 1. During assembly, a circuit board 10 is first installed on the housing of the motor 9, the connector 2 is fixed on the circuit board 10, and finally the rear cover housing 1 is vertically assembled. The sealing structure 3 is provided between the connector 2 and the rear cover housing 1, and the sealing mechanism 3 is filled with sealant, thus achieving a relatively simple seal.

[0024] like Figure 3 and Figure 4 As shown, the sealing structure 3 includes a sealant-receiving groove structure 4 and a rear cover sealing structure 5. The sealant-receiving groove structure 4 is located at the bottom of the connector 2, and the rear cover sealing structure 5 is located at the top of the rear cover housing 1, with its end inside the sealant-receiving groove structure 4. By injecting an appropriate amount of sealant into the sealant-receiving groove structure 4, after the groove structure 4 is filled, excess sealant overflows into the overflow channel 6. The overflow channel 6 is located at the gap between the integrated connector 2 and the rear cover housing 1. A double-layer sealant structure is formed on both the inner and outer sides of the annularly raised rear cover sealing structure 5, providing multiple guarantees for the product's protective stability and improving the stability and reliability of the product's sealing protection.

[0025] An overflow channel 6 is provided between the adhesive reservoir structure 4 and the back cover pressing structure 5, and an adhesive layer is provided inside the adhesive reservoir structure 4 and the overflow channel 6. The overflow channel 6 is located at the gap between the integrated connector 2 and the back cover shell 1. After the adhesive reservoir structure 4 is filled, it will enter the overflow channel 6. The overflow channel 6 is located inside the annular protrusion of the back cover pressing structure 5 and the adhesive reservoir structure 4. The adhesive enters here to form a layer of sealant. The adhesive enters outside the back cover pressing structure 5 and between the adhesive reservoir structure 4 to form another layer of sealant. A single layer of sealant provides poor protection, and once damaged, the sealing and protective function is lost. A double layer of sealant provides a better sealing effect.

[0026] The rear cover housing 1 has a first adhesive-blocking plane 7 on one side and an adhesive-receiving groove structure 4 has a second adhesive-blocking plane 8 on one side. The first adhesive-blocking plane 7 and the second adhesive-blocking plane 8 are used to prevent the sealant from being blocked, which can effectively control the area where the sealant flows and fills, preventing the sealant from overflowing from the sealing structure 3 in the electronic control unit and flowing onto the circuit board 10, contaminating electronic components, affecting the heat dissipation and other functions of electronic components, and causing unnecessary trouble for the inspection and rework of the product circuit board.

[0027] The back cover pressing structure 5 is an annular protrusion on the top of the back cover housing 1, and the adhesive receiving groove structure 4 is an annular groove on the bottom of the connector 2. The shape of the back cover pressing structure 5 is an annular protrusion extending inward from the top of the back cover housing 1. The back cover pressing structure 5 applies pressure to press the sealant to flow according to the designed structure. The adhesive receiving groove structure 4 is an annular groove extending outward from the bottom of the connector 2. The adhesive receiving groove structure 4 is used to fill the sealant.

[0028] A motor 9 is located at the bottom of the rear cover housing 1, and a circuit board 10 is located inside the rear cover housing 1. The circuit board 10 is fixed to the motor 9 by a housing frame 14, and the connector 2 is connected to the circuit board 10. In this embodiment, the circuit board 10 is installed on the motor 9, the connector 2 is installed on the circuit board 10, and finally the rear cover housing 1 is installed. A housing frame 14 is set between the circuit board 10 and the motor 9 for fixation. The housing frame 14 includes a triangular plate, and three fixing posts are fixed at the three corners of the triangular plate. The housing frame 14 plays a supporting role.

[0029] The circuit board 10 and the housing frame 14 are connected by bolts, and the connector 2 and the circuit board 10 are also connected by bolts. The top of the circuit board 10 and the housing frame 14 are connected by bolts, and the top of the motor 9 and the three fixing posts of the housing frame 14 are all connected by bolts. The housing frame 14 is located between the motor 9 and the circuit board 10. The bolt connection makes it more secure and easier to disassemble.

[0030] The connector 2 has a support post 11 at its bottom, which is mounted on the circuit board 10. The connector 2 and the circuit board 10 are fixed together by the support post 11.

[0031] Connector 2 is a one-piece structure. The one-piece structure of connector 2 facilitates installation and provides a more robust structure.

[0032] The adhesive reservoir structure 4 has a first chamfer 12 at one end, and the back cover adhesive pressing structure 5 has a second chamfer 13 at one end. The first chamfer 12 and the second chamfer 13 form a guide surface, which improves the fluidity of the sealing adhesive, makes the amount of adhesive flowing out of the overflow channel more uniform, and makes the adhesive line formed on the outer surface of the product more uniform and beautiful.

[0033] The working principle of this utility model is as follows: A steering motor with a sealing function includes a rear cover housing 1 and a connector 2. The connector 2 is disposed on the rear cover housing 1, and a sealing structure 3 is provided between the connector 2 and the rear cover housing 1. During assembly, a circuit board 10 is first installed on the housing of the motor 9, and the connector 2 is fixed on the circuit board 10. An appropriate amount of sealant is injected into the receiving groove structure 4. Finally, the rear cover housing 1 is vertically assembled. The sealant receiving groove structure 4 is located at the bottom of the connector 2, and the rear cover pressing structure 5 is located at the top of the rear cover housing 1. The end of the rear cover pressing structure 5 is located inside the sealant receiving groove structure 4. By injecting an appropriate amount of sealant into the sealant receiving groove structure 4, after the sealant receiving groove structure 4 is filled, the excess sealant overflows into the overflow channel 6. The overflow channel 6 is the gap between the integrated connector 2 and the rear cover housing 1. A double-layer sealant structure is formed on the inner and outer sides of the annular protruding rear cover pressing structure 5, providing multiple guarantees for the product's protective stability and improving the stability and reliability of the product's sealing protection. The rear cover housing 1 has a first adhesive-blocking plane 7 on one side and an adhesive-receiving groove structure 4 has a second adhesive-blocking plane 8 on one side. The first adhesive-blocking plane 7 and the second adhesive-blocking plane 8 are used to prevent the sealant from being blocked, which can effectively control the area where the sealant flows and fills, preventing the sealant from overflowing from the sealing structure 3 in the electronic control unit and flowing onto the circuit board 10, contaminating electronic components, affecting the heat dissipation and other functions of electronic components, and causing unnecessary trouble for the inspection and rework of the product circuit board.
