Description

Technical Field

[0001] This utility model relates to the field of brushless motor paint repair technology, and in particular to a brushless motor anti-rust paint pen. Background Technology

[0002] In the production process of automotive brushless motors, in order to improve the motor's aesthetics and durability and reduce the impact of surface corrosion, it is usually necessary to perform anti-rust treatment on the weight-reducing and balancing cutting areas of the motor housing and the laser marking areas of the controller.

[0003] Currently, the common practice is to apply rust-preventive paint to the housing or controller using a brush or cloth. However, brushes shed bristles and cloths become stained with dirt after frequent use, causing foreign matter to adhere to the surface of the housing or controller, affecting the appearance and rust prevention effect. Moreover, the application area is large, making it difficult to control the amount of rust-preventive paint used. Utility Model Content

[0004] This invention uses a special brushless motor anti-rust paint pen to apply anti-rust paint to the brushless motor, thereby overcoming the deficiencies in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a brushless motor rust-preventive paint pen, including a pen tube, wherein the pen tube stores rust-preventive paint;

[0006] One end of the pen tube is connected to the pen tip, and the other end is connected to the pen cap;

[0007] The pen tip is equipped with a pen refill, and the pen tip is connected to the inner cavity of the pen tube, so that the pen refill can contact the anti-rust paint inside the pen tube.

[0008] The pen tip is also equipped with a plug and a filter, and a top core is also provided inside the filter. The top core is hollow inside and serves as a connection channel between the inner cavity of the pen tube and the pen tip.

[0009] Preferably, the pen tip is threaded to the end of the pen tube.

[0010] Preferably, the pen refill is slidably inserted into the pen tip. When the pen refill contacts the surface of the brushless motor and is subjected to force, it slides inward to contact and push the top core into the inner cavity of the pen tube to absorb the anti-rust paint.

[0011] Preferably, a spring is fitted onto the top core, with one end of the spring abutting against the step of the top core and the other end contacting the filter.

[0012] Preferably, the plug is fixedly installed inside the filter, serving as the upper limit for the displacement of the top core.

[0013] Preferably, the portion of the pen refill protruding from the pen tip is trapezoidal, and the material of the pen refill is polyester fiber.

[0014] Preferably, the pen tube contains at least one stirring ball.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This brushless motor rust-preventive paint pen, through its simple structure, achieves the following: no foreign matter contamination during rust-preventive paint application, controllable dosage, easy replacement, and durability, effectively improving work efficiency and achieving the expected purpose.

[0017] 2. The brushless motor-coated rust-proof paint pen's lead can be removed and replaced after wear. The lead is made of polyester fiber, which is characterized by high porosity, wear resistance and resistance to splitting, relatively soft hardness, suitable handwriting, long service life, adjustable rust-proof paint application, no foreign matter pollution, reasonable structural layout, simple and compact mechanism, easy operation, convenient use, high work efficiency, and novel design.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] This utility model provides a brushless motor rust-preventive paint application pen. Please refer to [link / reference]. Figure 1-3 The pen tube 1 contains rust-preventive paint; one end of the pen tube 1 is connected to the pen tip 2, and the other end is connected to the pen cap 3; the pen tip 2 contains a pen refill 4, and the pen tip 2 communicates with the inner cavity of the pen tube 1, so that the pen refill 4 can contact the rust-preventive paint in the pen tube 1; the pen tip 2 also contains a plug 5 and a filter 6, and the filter 6 also contains a top core 7, which is hollow inside and serves as a connection channel between the inner cavity of the pen tube 1 and the pen tip 2.

[0026] Specifically, the pen tip 2 is threadedly connected to the end of the pen tube 1; the pen core 4 is slidably inserted into the pen tip 2, and when the pen core 4 contacts the surface of the brushless motor and is subjected to force, it slides inward to contact and push the top core 7 into the inner cavity of the pen tube 1 to absorb the anti-rust paint.

[0027] Furthermore, a spring 8 is fitted onto the top core 7, with one end of the spring 8 abutting against the step of the top core 7 and the other end contacting the filter 6. When the top core 7 slides inward, the spring 8 compresses and stores force until the top core 7 loses its force, at which point the top core 7 returns to its original position under the action of the spring 8.

[0028] In this embodiment, the plug 5 is fixedly installed inside the filter 6, serving as the upper limit of the displacement of the top core 7.

[0029] Specifically, the portion of the pen refill 4 that protrudes from the pen tip 2 is trapezoidal, and the material of the pen refill 4 is polyester fiber.

[0030] In this embodiment, the pen tube 1 is provided with at least one stirring ball 9. Under the action of gravity, pressure is applied to make the anti-rust paint more easily pass through the top core 7 and penetrate into the pen core 4.

[0031] During touch-up painting, pressing the pen refill 4 compresses the spring 8, causing the top core 7 to extend into the pen tube 1 and draw in the rust-preventive liquid. The stirring bead 7 inside the pen tube 1 applies pressure, making it easier for the rust-preventive paint to pass through the top core 7 and penetrate into the pen refill 4. In actual use, the operator holds the pen tube 1 and presses the pen refill 4 to circulate the liquid, achieving the purpose of applying rust-preventive paint to the brushless motor.

[0032] The brushless motor-coated rust-preventive paint pen has a removable and replaceable lead after wear. The lead is made of polyester fiber, which is characterized by high porosity, wear resistance and resistance to splitting, relatively soft hardness, suitable handwriting, long service life, adjustable rust-preventive paint application, no foreign matter pollution, reasonable structural layout, simple and compact mechanism, easy operation, convenient use, high work efficiency, and novel design.

[0033] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
