Description

Technical Field

[0001] The present application relates to the field of wire outlet structures, and in particular to a motor wire outlet structure with a waterproof function. Background Art

[0002] Water leakage usually occurs at the output terminal of the motor. In order to reduce the possibility of water leakage, a waterproof structure is usually added at the output terminal.

[0003] Current waterproofing mechanisms primarily rely on rubber pads or threaded plastic connectors. However, rubber pads can easily shift with the movement of wires, leaving the terminals vulnerable to water leakage. Plastic connectors, on the other hand, have poor structural strength and are easily damaged by the environment. Furthermore, when used with thin-walled housings, these connectors can experience poor connection stability, resulting in poor waterproofing performance at the motor's output terminals. This requires further improvement. Utility Model Content

[0004] In order to improve the above problems, the present application provides a motor wire output structure with waterproof function.

[0005] This application provides a waterproof motor output structure, which adopts the following technical solutions:

[0006] A motor wire outlet structure with a waterproof function is arranged on a casing, comprising a pressure plate and a sealing ring for the wire to pass through. The sealing ring is passed through the casing, and the pressure plate abuts against the side of the sealing ring facing away from the casing. The pressure plate is connected to the casing through a connecting component.

[0007] By employing this technical solution, workers insert the sealing ring into the housing, allowing the wires to pass through the ring. They then place a pressure plate against the ring to secure it. They then secure the pressure plate to the housing, pressing it against the ring. Simultaneously, the housing presses against the ring from the other side, providing a double stop for the ring. This reduces the possibility of a gap between the ring and the housing, thereby improving the waterproof performance of the motor's wire outlet.

[0008] Preferably, an extrusion slope is provided on a side of the sealing ring facing away from the pressure plate, and the extrusion slope is deformed after contacting the housing.

[0009] By adopting the above technical solution, after the sealing ring is stuck in the casing, the extrusion bevel is deformed after being squeezed. At the same time, the sealing ring at the extrusion bevel is squeezed, which makes the sealing ring further press against the wire, reducing the possibility of a gap between the sealing ring and the wire, thereby further improving the waterproof performance at the motor output terminal.

[0010] Preferably, a cover is provided on the pressure plate, the cover is protruding toward a side away from the sealing ring, and the sealing ring abuts against a side of the cover close to the housing.

[0011] By adopting the above technical solution, the cover increases the contact area between the pressure plate and the sealing ring, so that the pressure plate can provide more stable positioning for the sealing ring.

[0012] Preferably, a first abutting arc surface is formed on a side of the sealing ring facing away from the housing, and a second abutting arc surface is formed on a side of the cover shell close to the housing, and the second abutting arc surface abuts against the first abutting arc surface.

[0013] By adopting the above technical solution, the first abutting arc surface and the second abutting arc surface cooperate with each other, further increasing the contact area between the pressure plate and the sealing ring, thereby further improving the limiting ability of the pressure plate on the sealing ring.

[0014] Preferably, a connecting seat is provided on the casing, the pressure plate is in contact with the connecting seat, the connecting assembly includes a connecting column and a connecting ring, the connecting column passes through the connecting seat and the pressure plate, the connecting ring is threadedly connected to the connecting column, and the connecting ring is in contact with the side of the pressure plate facing away from the connecting seat.

[0015] By adopting the above technical solution, when a worker needs to use a pressure plate to fix the sealing ring, the worker places the pressure plate on the connecting seat, and then passes the connecting column through the connecting seat and the pressure plate. The worker then installs the connecting ring on the connecting column and makes the connecting ring press against the pressure plate. At this time, the pressure plate can press against the sealing ring, completing the fixing of the pressure plate.

[0016] Preferably, the two connecting seats are arranged opposite to each other, and the two connecting seats are both threadedly connected with an adjustment column. Each adjustment column is rotatably connected with a reinforcement plate, and the reinforcement plate is rotatably connected to the casing. The two opposite reinforcement plates abut against each other and clamp the sealing ring.

[0017] By employing this technical solution, after a worker secures the pressure plate, they rotate the adjustment column, which drives the corresponding reinforcement plate toward the sealing ring, forcing it to press against the ring. When both opposing reinforcement plates abut the sealing ring, they abut against each other, completing their movement. At this point, the two reinforcement plates simultaneously clamp and deform the sealing ring, further reducing the possibility of gaps between the wires and the sealing ring, thereby further improving the waterproof performance at the motor's output terminal.

[0018] Preferably, a clamping plate is provided on one of the reinforcement plates, and a clamping groove is provided on the other reinforcement plate, and the clamping plate is arranged in the clamping groove.

[0019] By adopting the above technical solution, the clamping plate cooperates with the clamping groove, which facilitates the positioning of the two opposing reinforcement plates and reduces the possibility of excessive deformation of the sealing ring due to excessive movement of the reinforcement plate.

[0020] Preferably, a plurality of waterproof rings are evenly arranged on the inner wall of the sealing ring, and each of the waterproof rings is tilted toward the direction of the pressure plate.

[0021] By adopting the above technical solution, after the reinforcement plate is pressed against the sealing ring, the sealing ring is squeezed, and at the same time, each waterproof ring is squeezed and pressed against the wire, further reducing the possibility of a gap between the wire and the sealing ring, thereby further improving the waterproof performance at the motor output terminal.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By providing a pressure plate and a connecting assembly, the connecting assembly is used to fix the pressure plate, so that the pressure plate and the housing provide dual position limits for the sealing ring, reducing the possibility of the sealing ring moving during use, thereby improving the waterproof performance at the motor outlet;

[0024] 2. By providing a reinforcement plate, two reinforcement plates clamp the sealing ring, reducing the possibility of a gap between the wire and the sealing ring, thereby further improving the waterproof performance at the motor outlet. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] Example 1:

[0032] The first embodiment of the present application discloses a motor outlet structure with waterproof function. Figure 1 A waterproof motor outlet structure, mounted on a housing 1, comprises a pressure plate 2 and a sealing ring 3 through which the wires pass. The sealing ring 3 is inserted through the housing 1, with the pressure plate 2 abutting against the side of the sealing ring 3 facing away from the housing 1. The pressure plate 2 is connected to the housing 1 via a connecting assembly 4. After a worker secures the pressure plate 2 to the housing 1 using the connecting assembly 4, the pressure plate 2 and the housing 1 cooperate to provide a double stop for the sealing ring 3, reducing the possibility of the sealing ring 3 separating from the housing 1 during use and the possibility of a gap forming between the sealing ring 3 and the housing 1, thereby improving the waterproof performance of the motor outlet.

[0033] Reference Figure 2 The side of the sealing ring 3 facing away from the pressure plate 2 has an extrusion slope 31. This extrusion slope 31 deforms upon contact with the housing 1. This deformation causes the sealing ring 3 to press against the conductor at this location, minimizing the risk of a gap between the sealing ring 3 and the conductor, thereby further improving the waterproof performance of the motor's output terminal. The sealing ring 3 is made of rubber.

[0034] Reference Figure 1 and Figure 2 A cover shell 21 is fixed on the pressure plate 2 , and the cover shell 21 protrudes toward the side away from the sealing ring 3 , and the sealing ring 3 abuts against the side of the cover shell 21 close to the housing 1 .

[0035] In order to increase the contact area between the cover shell 21 and the sealing ring 3, a first abutting arc surface 32 is provided on the side of the sealing ring 3 facing away from the housing 1, and a second abutting arc surface 211 is provided on the side of the cover shell 21 close to the housing 1. The second abutting arc surface 211 abuts against the first abutting arc surface 32.

[0036] After the worker places the pressure plate 2 against the sealing ring 3, the first abutting arc surface 32 on the sealing ring 3 abuts against the second abutting arc surface 211 on the cover shell 21, increasing the contact area between the cover shell 21 and the sealing ring 3, that is, increasing the contact area between the pressure plate 2 and the sealing ring 3, so that the pressure plate 2 can limit the sealing ring 3 more stably.

[0037] Reference Figure 1 A connecting seat 11 is fixed to the housing 1, and the pressure plate 2 abuts against the connecting seat 11. The connecting assembly 4 includes a connecting column 41 and a connecting ring 42. The connecting column 41 passes through the connecting seat 11 and the pressure plate 2, and the connecting ring 42 is threadedly connected to the connecting column 41, and the connecting ring 42 abuts against the pressure plate 2.

[0038] When the pressing plate 2 needs to be fixed, the worker places the pressing plate 2 against the connecting seat 11, and then passes the connecting column 41 through the connecting seat 11 and the pressing plate 2. The worker then installs the connecting ring 42 on the connecting column 41, so that the connecting ring 42 presses against the pressing plate 2, completing the fixing of the pressing plate 2, so that the pressing plate 2 can more stably limit the sealing ring 3.

[0039] The working principle of Example 1 of the present application is as follows: Sealing ring 3 guides the wires, preventing gaps from forming between the wires and housing 1. Workers then use connecting assembly 4 to secure pressure plate 2 to housing 1, providing dual position restraint for sealing ring 3. This reduces the possibility of misalignment of sealing ring 3 during use, thereby improving the waterproof performance at the motor's outlet terminal.

[0040] Example 2:

[0041] Reference Figure 3 , which differs from the first embodiment of the present application in that: two connecting seats 11 are arranged opposite each other, and each connecting seat 11 is threadedly connected to an adjustment column 5. Each adjustment column 5 is rotatably connected to a reinforcement plate 6, and the reinforcement plate 6 is slidably connected to the inner wall of the housing 1, and the reinforcement plate 6 is arranged in a semicircular shape.

[0042] After securing the pressure plate 2, the worker rotates the adjustment column 5. Due to the threaded connection between the adjustment column 5 and the connection base 11, the rotational connection between the adjustment column 5 and the reinforcement plate 6, and the sliding connection between the reinforcement plate 6 and the housing 1, the movement of the adjustment column 5 drives the reinforcement plate 6. After both opposing reinforcement plates 6 abut against the sealing ring 3, the two reinforcement plates 6 abut, effectively clamping the sealing ring 3. At this point, the sealing ring 3 presses even more tightly against the wire, further reducing the possibility of a gap between the wire and the sealing ring 3, thereby further improving the waterproof performance at the motor output terminal.

[0043] Reference Figure 3 A clamping plate 61 is fixed to one of the reinforcing plates 6, and a clamping groove 62 is formed on the other reinforcing plate 6, with the clamping plate 61 being disposed in the clamping groove 62. The cooperation between the clamping plate 61 and the clamping groove 62 not only increases the connection stability between the two reinforcing plates 6, but also reduces the possibility of excessive movement of the reinforcing plate 6 and causing excessive deformation of the sealing ring 3.

[0044] Reference Figure 3 and Figure 4 Several waterproof rings 33 are evenly fixed to the inner wall of the sealing ring 3, and each waterproof ring 33 is tilted toward the pressure plate 2. After the two reinforcing plates 6 clamp the sealing ring 3, the waterproof rings 33 are squeezed and forced to press against the wires, further reducing the possibility of gaps between the wires and the sealing ring 3, thereby further improving the waterproof performance at the motor output terminal.

[0045] The implementation principle of the second embodiment of the present application is: the two relative reinforcement plates 6 clamp the sealing ring 3, further reducing the possibility of the sealing ring 3 moving during use, and at the same time making each waterproof ring 33 pressed tightly against the wire, making it less likely for a gap to appear between the wire and the sealing ring 3, thereby further improving the waterproof performance at the motor output terminal.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
