Description

Technical Field

[0001] This utility model relates to the field of motor device technology, and in particular to a housing-illuminated motor. Background Art

[0002] Electric motors are common driving components and are widely used in various products with moving functions. Most existing motors only have driving functions and do not have decorative or display functions. However, in certain fields, motors with lighting effects, such as hub motors, are needed to serve decorative, lighting, and indicator purposes.

[0003] In existing technologies, such as the rotary light-emitting component and light-emitting motor with application number 202221185489.0, a rotary drive component, a fixed base, a light-emitting component, and a connecting structure are provided. By cooperating with the light-emitting component, an electrical connection can be established during the rotation of the light-emitting motor to supply power to the light-emitting component, thereby achieving the light-emitting display function. However, one end of the connecting component is fixed to the fixed base, while the other end slides in contact with the light-emitting component, forming a closed circuit through substantial contact. Similarly, the spring-loaded light-emitting hub motor with application number 202020266492.X and the pin-type light-emitting hub motor with application number 202020267147.8 also form a closed circuit through substantial contact. In the above forms, prolonged contact between the connecting component and related parts may cause damage or poor contact, resulting in the light strip failing to light up properly. Utility Model Content

[0004] The purpose of this utility model is to provide a housing-emitting motor that generates a magnetic field by energizing a transmitting element fixed on the motor shaft or stator assembly. The receiving element is in the generated magnetic field and moves relative to the magnetic field as the housing rotates, generating current. This is used to make the light strip emit light after being energized. This changes the form that requires contact through a conductive element to achieve closed-loop energization, and the structure is simpler.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a housing-emitting motor, comprising a drive mechanism and a housing, wherein the drive mechanism comprises a motor shaft, a stator assembly, and a rotor assembly, the stator assembly and the stator assembly being disposed on the motor shaft, and a emitting element being provided on the motor shaft or the stator assembly, the emitting element generating a magnetic field after being energized, the housing being rotatably sleeved on the motor shaft and forming an inner cavity, the stator assembly and the rotor assembly being located in the inner cavity, the rotor assembly being drively connected to the housing, a receiving element being provided on the inner wall of the housing, the receiving element being in the magnetic field and generating current through relative movement, the receiving element being electrically connected to a lamp strip disposed on the outer wall of the housing.

[0006] As a further optimization, the rotor assembly includes a rotor and magnets. The rotor is rotatably mounted on the motor shaft, and the magnets are disposed on the side wall of the rotor and are disposed opposite to the wound coils on the stator assembly. The housing is connected to the rotor.

[0007] As a further optimization, the rotor assembly includes a rotor, magnets, and a speed reducer. The rotor is rotatably mounted on the motor shaft. The magnets are mounted on the side wall of the rotor and are positioned opposite to the wound coils on the stator assembly. One end of the speed reducer is connected to the rotor, and the other end is connected to the housing, enabling the motor to output power at a certain speed reduction ratio.

[0008] As a further optimization, the reduction component includes a sun gear, a planetary carrier and gears, and an internal gear ring. The sun gear is fixedly connected to the rotor, the planetary carrier and gears are fixed on the motor shaft and mesh with the sun gear, and the internal gear ring is disposed on the inner wall of the housing and meshes with the planetary carrier and gears.

[0009] As a further optimization, the housing is provided with a light strip groove, the light strip is disposed in the light strip groove, and the housing is provided with a light strip cover plate to seal the light strip groove, which can provide excellent protection for the light strip.

[0010] As a further optimization, the housing includes a shell and an end cap that are locked together, and the shell and the end cap are respectively sleeved on the motor shaft by bearings; the light strip is respectively provided on the shell and the end cap.

[0011] As a further optimization, the LED strip on the housing and the LED strip on the end cap are connected in parallel, which facilitates energizing the two LED strips on the housing and the end cap respectively.

[0012] As a further optimization, the light strip is an LED light.

[0013] As a further optimization, the transmitting element is electrically connected to the stator circuit board in the stator assembly, which facilitates the power-on process of the transmitting element.

[0014] As a further optimization, the transmitting element and the receiving element are both circuit board structures.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By energizing a transmitting element fixed on a motor shaft or stator assembly to generate a magnetic field, and having a receiving element in the generated magnetic field that moves relative to the magnetic field as the housing rotates to generate current, the light strip emits light after being energized. This changes the previous method of requiring contact through a conductive element to achieve a closed loop before energizing, resulting in a simpler structure. Attached Figure Description

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1 to 2 As shown, a housing-illuminated motor includes a drive mechanism and a housing 40. The drive mechanism includes a motor shaft 10, a stator assembly 20, and a rotor assembly 30. The stator assembly 20 and stator assembly 30 are mounted on the motor shaft 10, and an emitting element 200 is provided on the motor shaft 10 or the stator assembly 20. Preferably, the emitting element 200 is provided on the stator assembly 20. The emitting element 200 can generate a magnetic field when energized. The housing 40 is rotatably fitted onto the motor shaft 10 and forms an inner cavity. The stator assembly 20 and the rotor assembly 30 are located in the inner cavity. The rotor assembly 30 is drively connected to the housing 40. A receiving element 400 is provided on the inner wall of the housing 40. The receiving element 400 is in the magnetic field and generates current through relative movement. The receiving element 400 is electrically connected to a light strip 50 disposed on the outer wall of the housing 40. Preferably, the light strip 50 is an LED light.

[0021] In this invention, the rotor assembly 30 is rotatably mounted on the motor shaft 10. It rotates around the motor shaft 10 through interaction with the stator assembly 20 and is connected to the housing 40. Therefore, it drives the housing 40 to rotate around the motor shaft 10. During the rotation of the housing 40, its receiving element 400 is also in a rotating state and moves relative to the transmitting element 200 mounted on the stator assembly 20. When the transmitting element 200 is energized, it generates a magnetic field, which induces electricity in the receiving element 400, which is parallel to and moves relative to it. Therefore, the light strip 50, which is electrically connected to the receiving element 400, emits light after being energized. The light strip 50 produces a cyclic rotating light effect as the housing 40 rotates.

[0022] More specifically, after the transmitting element is powered on, the circuit generates an oscillation signal of a specific frequency. After the power is amplified by the amplifier circuit, the signal is radiated into space by the PCB coil on the transmitting element. The PCB coil is equivalent to an inductor L1, and the coil line resistance is equivalent to R1. Together with the capacitor C1 connected in parallel with the coil, they form an RLC resonance. After resonance, the signal will radiate outward with maximum efficiency. When the receiving element is close to the transmitting element, the PCB coil L2 on the receiving element and the capacitor C2 also form an RLC resonance. The receiving element will receive the specific frequency signal in space with maximum efficiency. At this time, electrical energy is coupled from the transmitting element to the receiving element. This energy is used to drive the LED light strip (R0) to light up. Since the electrical energy driving the LED is a high-frequency signal, which is much higher than the flicker frequency that the human eye can perceive, it appears to the human eye as a continuous light.

[0023] This invention generates a magnetic field by energizing a transmitting element 200 fixed on a motor shaft 10 or a stator assembly 20. The receiving element 400 is in the generated magnetic field and moves relative to the magnetic field as the housing 40 rotates, generating current. This current is used to make the light strip 50 emit light after being energized. This invention changes the conventional form that requires contact through a conductive element to achieve closed-loop energization, and the structure is simpler.

[0024] Preferably, the housing 40 is provided with a light strip groove 401, the light strip 50 is disposed in the light strip groove 401, and the housing 40 is provided with a light strip cover plate 402 to seal the light strip groove 401. The light strip cover plate 402 is light-transmitting. Through the above arrangement, the light strip 50 can be disposed in the housing 40 to avoid direct contact with the external environment, thereby improving the sealing effect and providing excellent protection for the light strip 50.

[0025] Furthermore, the outer casing 40 includes a housing 41 and an end cap 42 that are interlocked. The housing 41 and the end cap 42 are respectively mounted on the motor shaft 10 via bearings. LED strips 40 are respectively provided on the housing 41 and the end cap 42. Of course, the housing 41 and the end cap 42 are respectively provided with LED strip grooves 401 for mounting the LED strips 50, and are respectively sealed by LED strip cover plates 402. Based on the above, LED strips are provided on both sides of the outer casing 40, and the LED strips 50 on the housing 41 and the end cap 42 are configured in parallel.

[0026] Preferably, the transmitting element 200 is electrically connected to the stator circuit board in the stator assembly 20, and the transmitting element 200 and the receiving element 400 are both circuit board structures.

[0027] In one embodiment of this utility model, the rotor assembly 30 includes a rotor 31 and a magnet 32. The rotor 31 is rotatably mounted on the motor shaft 10. The magnet 32 ​​is mounted on the side wall of the rotor 31 and is positioned opposite to the winding coil 21 on the stator assembly 20. The outer shell 40 is connected to the rotor 30. When the winding coil 21 is energized, its interaction with the magnet 32 ​​causes the magnet 32 ​​to rotate with the rotor 31. Thus, the rotation of the rotor assembly 30 drives the outer shell 40 to rotate.

[0028] In another embodiment of this utility model, the rotor assembly 30 includes a rotor 31, a magnet 32, and a speed reducer. The rotor 31 is rotatably mounted on the motor shaft 10. The magnet 32 ​​is disposed on the side wall of the rotor 31 and is positioned opposite to the wound coil 21 on the stator assembly 20. One end of the speed reducer is connected to the rotor 31, and the other end is connected to the housing 40. Specifically, the speed reducer includes a sun gear 321, a planetary support, a gear 322, and an internal gear ring 323. The sun gear 321 and the rotor 31 are connected by a screw... The planetary support and gear 322 are fixed to the motor shaft 10 with bolts and locks. The gears in the planetary support and gear 322 mesh with the sun gear 321. The internal gear ring 323 is interference-fitted to the inner wall of the outer casing 40 and meshes with the gears in the planetary support and gear 322. The rotor 31 drives the sun gear 321 to rotate synchronously. The sun gear 321 drives the outer casing 40 to rotate through the gears in the planetary support and gear 322 and the internal gear ring 323. The motor can output at a certain reduction ratio by setting the above-mentioned speed reduction components.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
