Description

Technical Field

[0001] This utility model belongs to the field of fascia gun accessories, specifically relating to a fascia gun motor assembly. Background Technology

[0002] A fascia gun is a device that uses a reciprocating linear motion nozzle to massage muscles. Existing fascia guns mainly consist of three parts: a massage component, a transmission component, and a motor component. The motor component drives the eccentric wheel to rotate continuously, which in turn drives the massage component to move back and forth via the transmission component. Specifically, the motor component includes a brushless motor, an eccentric wheel, a battery, a charging module, and a control motherboard.

[0003] Existing fascia gun shells consist of two connected parts: a horizontal tube and a vertical tube. The horizontal tube houses the transmission components and massage components, while the vertical tube houses the motor assembly and is used for the operator's grip. During operation, the components that continuously generate heat include the motor and battery, both located within the vertical tube. Existing fully enclosed vertical tubes typically only have a heat dissipation vent at the bottom. However, the limited internal space of the vertical tube makes heat dissipation difficult, posing a risk of overheating and damage to areas far from the vent. Furthermore, areas prone to heat buildup are also where the operator grips the gun, potentially making it difficult to hold the fascia gun for extended periods. On the other hand, existing fascia guns often use a one-piece shell with a removable cover only at the end of the horizontal or vertical tube. Disassembly and assembly require specialized tools, making it inconvenient for users to inspect or replace the motor assembly, leading to a buildup of malfunctions and increasing the rate of fascia gun failure. To address these problems, this invention provides a fascia gun motor assembly. Utility Model Content

[0004] The purpose of this invention is to provide a fascia gun motor assembly in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] This utility model provides a fascia gun motor assembly, including a protective shell and a brushless motor, an eccentric wheel, a control motherboard, and a rechargeable battery module disposed within the protective shell. Heat sinks are provided on the outside of both the brushless motor and the rechargeable battery module. The protective shell includes a docking cylinder and a gripping cylinder disposed below the docking cylinder. Heat sinks are provided above the docking cylinder and below the gripping cylinder.

[0007] As a further optimization of this utility model, the heat sink includes a plurality of heat sinks arranged in a ring array.

[0008] As a further optimization of this utility model, the heat dissipation cylinder includes a support and a ventilation mesh.

[0009] As a further optimization of this utility model, the bracket and the docking cylinder are screwed together.

[0010] As a further optimization of this utility model, the docking cylinder is provided with positioning rings that correspond one-to-one with the brushless motor and the rechargeable battery module. The brushless motor and the rechargeable battery module are both connected to the heat sink on the outside in a snap-fit ​​manner.

[0011] As a further optimization of this utility model, the docking cylinder is provided with a docking sleeve for docking the fascia gun shell.

[0012] As a further optimization of this utility model, the eccentric wheel is located inside the docking cylinder, the control motherboard is embedded on the side of the docking cylinder, the brushless motor is located above the eccentric wheel, and the rechargeable battery module is located below the eccentric wheel.

[0013] The beneficial effects of this utility model are as follows:

[0014] The fascia gun motor assembly provided by this utility model, through the cooperation of heat sink and heat sink cylinder, achieves the rapid external conduction of the heat generated by the brushless motor and battery during operation to the heat sink, and the rapid heat dissipation effect is achieved by the air commutating through the heat sink cylinder, which effectively avoids the problem of heat accumulation, reduces the probability of overheating damage to the motor assembly, and enables the fascia gun to operate stably and safely for a long time.

[0015] By combining the connecting pipe, docking sleeve, and bracket, a protective shell that can be disassembled into sections is provided for the motor assembly. Users can remove the protective shell to expose the internal brushless motor and battery, thereby completing the inspection and replacement operations. The disassembly and assembly method is convenient and efficient, making it easy for users to inspect and repair themselves, and further improving the safety of using the fascia gun motor assembly.

[0020] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1-3 As shown, the fascia gun motor assembly of this embodiment includes a protective shell and a brushless motor 6, an eccentric wheel 7, a control main board 8, and a rechargeable battery module 9 disposed within the protective shell. Heat sinks 10 are fitted on the outer sides of both the brushless motor 6 and the rechargeable battery module 9. The protective shell includes a docking cylinder 1 and a gripping cylinder 2 disposed below the docking cylinder 1. The gripping cylinder 2 is provided with a handle. Heat sinks are provided above the docking cylinder 1 and below the gripping cylinder 2.

[0023] The eccentric wheel 7 is located inside the docking cylinder 1, the control motherboard 8 is embedded on the side of the docking cylinder 1, the brushless motor 6 is located above the eccentric wheel 7, and the rechargeable battery module 9 is located below the eccentric wheel 7. In this embodiment, the control motherboard 8, the brushless motor 6, and the rechargeable battery module 9 are all conventional technologies and do not involve protection.

[0024] The protective shell of the motor assembly of the fascia gun can be directly used as part of the fascia gun shell, replacing the vertical tube of the existing fascia gun. The horizontal tube on the existing fascia gun, which is used to house the transmission mechanism, can be connected with the docking tube 1 to form a complete fascia gun shell. When in use, the operator can hold the gripping tube 2 with one hand.

[0025] When the fascia gun is in operation, the brushless motor 6 and the rechargeable battery module 9 continuously generate heat. The heat generated during operation is quickly transferred to the heat sink 10, thereby avoiding heat buildup on the brushless motor 6 and the battery and reducing the probability of overheating damage. During the heat dissipation process, the heat sink also provides internal and external ventilation channels for the fascia gun, achieving efficient heat dissipation in conjunction with the heat sink 10.

[0026] Preferably, the heat sink 10 includes a number of heat sinks arranged in a ring array. The heat sinks arranged around the heat sinks achieve multi-directional heat conduction and heat dissipation, resulting in better heat dissipation. It also has good compatibility with the cylindrical protective shell and high space utilization within the fascia gun.

[0027] The heat sink includes a bracket 4 and a ventilation mesh 5.

[0028] The bracket 4 is threadedly connected to the docking cylinder 1.

[0029] The docking cylinder 1 is equipped with positioning rings 11 that correspond one-to-one with the brushless motor 6 and the rechargeable battery module 9. Both the brushless motor 6 and the rechargeable battery module 9 are engaged with the heat sink 10 on the outside.

[0030] The docking cylinder 1 is provided with a docking sleeve 3 for docking the fascia gun housing. The horizontal tube on the fascia gun, which is used to house the transmission mechanism, is threadedly connected to the docking sleeve 3, making the connection stable and easy to disassemble and assemble.

[0031] The two positioning rings 11 are used to apply pressure to the brushless motor 6 and the battery respectively to achieve a fixing effect. When inspecting the inside of the fascia gun, first separate the protective shell from the horizontal tube used to house the transmission mechanism, then separate the two brackets 4 from the docking tube 1, and finally pull out the two heat sinks 10, thereby exposing the brushless motor 6 and the rechargeable battery module 9, which is convenient for disassembly, repair or replacement.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
