Description

Technical Field

[0001] This utility model relates to a massager, specifically to a battery protection structure for a massager. Background Technology

[0002] The protective sleeves for batteries in the prior art are made of rigid materials (such as plastic), which are easily damaged when impacted by external forces, thus damaging the battery in the heat insulation shield. Moreover, the assembly of the battery protective sleeves is complicated.

[0003] Massagers have become increasingly technologically advanced in various aspects, with the battery being the core component. Batteries are typically fixed directly to a battery holder inside the massager. However, most existing massagers are made of plastic, which means they cannot provide adequate protection in the event of a short circuit or explosion of the battery. Summary of the Invention

[0004] The purpose of this invention is to address the problem of the lack of a protective structure for batteries in the prior art by providing a protective structure for massager batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery protection structure for a massager, comprising...

[0006] The massage mechanism includes two symmetrically arranged massage heads, which simulate kneading and rotating techniques by rotating.

[0007] A rechargeable battery, installed inside the massage mechanism, is used to provide power to the massage mechanism;

[0008] The protective structure includes a front cover, a rear cover, and a protective shell. Both the front and rear covers are connected to the protective shell with screws, enhancing the overall structural stability. The inner walls of the protective shell have recessed ends for screw installation, effectively preventing screws from penetrating or impacting the battery, thus reducing the risk of damage. The front cover also has a cable exit hole, providing a convenient outlet for battery cables, avoiding cable entanglement, and improving overall user comfort and flexibility.

[0009] Furthermore, both the front and rear covers have outwardly protruding arc-shaped surfaces in the center, the curvature of which matches the curvature of the rechargeable battery. These arc-shaped surfaces reduce the gap between the battery and the casing. This close-fitting design also restricts the position of the rechargeable battery, placing it in the center of the protective structure.

[0010] Furthermore, the avoidance end is composed of several equally spaced avoidance rails. The distance between the avoidance rails is less than the screw diameter, ensuring that the screw can be firmly positioned during installation and preventing the screw from slipping or shifting due to excessive gaps during installation. The two avoidance rails in the middle are provided with threaded holes that are compatible with the screw, so that the screw can be perfectly connected, improving installation efficiency and accuracy.

[0011] Furthermore, the protective structure is made of aluminum alloy.

[0012] Furthermore, the massage mechanism includes

[0013] The shell serves as a carrier;

[0014] The transmission mechanism is installed inside the housing and serves as the power output end;

[0015] The reduction mechanism, installed inside the housing, is connected to the transmission mechanism. The reduction mechanism converts the high-speed rotation of the transmission system into a lower speed or torque suitable for the massage effect, thus improving the smooth operation of the massage head.

[0016] The massage head is mounted on the housing and connected to the deceleration mechanism located inside the housing;

[0017] The circuit board, installed inside the housing, is electrically connected to the transmission mechanism and rechargeable battery. It connects the transmission mechanism, reduction gear, and rechargeable battery to achieve electrical control and management, ensuring equipment safety. The circuit board not only provides a precise control system but may also include overcurrent protection, short-circuit protection, and other functions, extending its service life and improving safety.

[0018] All components of the massage mechanism are integrated into the housing, ensuring a compact overall structure.

[0019] Furthermore, the reduction mechanism consists of a primary gear and a secondary gear. The transmission mechanism drives the primary gear, while the secondary gear meshes with the primary gear, and the secondary gear drives the massage head. The combination of the primary and secondary gears forms a progressively slower transmission mechanism, effectively converting the high-speed rotation of the transmission system into a lower-speed output. The combined design of the primary and secondary gears allows the reduction mechanism to achieve effective power transmission within a small space. This structure saves internal space without sacrificing performance, ensuring the compactness and aesthetics of the entire device.

[0020] Furthermore, the transmission mechanism is a dual-head motor, with lead screws at both ends. Each lead screw drives a reduction mechanism, and each reduction mechanism drives a massage head.

[0021] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the front cover, rear cover and protective shell of the protective structure can form an effective physical barrier to ensure that the battery is not easily damaged, and at the same time prevent the battery from short-circuiting or causing accidents.

Detailed Implementation

[0028] See Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a massager battery protection structure, which includes...

[0029] The massage mechanism 1 includes two symmetrically arranged massage heads 14, which simulate kneading and rotating techniques by rotating.

[0030] The rechargeable battery 2 is installed inside the massage mechanism 1 and is used to provide power to the massage mechanism 1.

[0031] The protective structure 3 includes a front cover 31, a rear cover 32, and a protective shell 33. The front cover 31, rear cover 32, and protective shell 33 of the protective structure 3 can form an effective physical barrier to ensure that the battery is not easily damaged, while preventing the battery from short-circuiting or causing accidents.

[0032] Both the front cover 31 and the rear cover 32 are connected to the protective shell 33 by screws, enhancing the overall structural stability. The inner wall of the protective shell 33 has avoidance ends 331 at both ends for screw installation. This design effectively prevents screws from penetrating or colliding with the battery, reducing the risk of damage to the internal battery. The front cover 31 also has a cable outlet hole 311, providing a convenient outlet for the battery cables, avoiding cable entanglement, and improving overall user comfort and flexibility.

[0033] More specifically, both the front cover 31 and the rear cover 32 have outwardly protruding arc surfaces 34 in the middle, the curvature of which matches the curvature of the rechargeable battery 2. The arc surfaces 34 reduce the gap between the battery and the casing. This close-fitting design also restricts the position of the rechargeable battery 2, placing it in the center of the protective structure 3.

[0034] More specifically, the avoidance end 331 consists of several equally spaced avoidance rails 3311. The spacing between the avoidance rails 3311 is smaller than the screw diameter, ensuring that the screw can be firmly positioned during installation and preventing slippage or displacement of the screw due to excessive gaps during installation. Furthermore, the two avoidance rails 3311 in the middle are provided with threaded holes 3312 that fit the screw, allowing for perfect screw alignment and improving installation efficiency and accuracy.

[0035] The specific massage mechanism 1 includes a housing 11 that serves as a carrier;

[0036] A transmission mechanism 12 is installed inside the housing 11, and the transmission mechanism 12 serves as a power output end;

[0037] The reduction mechanism 13 is installed inside the housing 11 and is connected to the transmission mechanism 12. The reduction mechanism 13 converts the high-speed rotation of the transmission system into a lower speed or torque suitable for the massage effect, thereby improving the smooth operation of the massage head 14.

[0038] A massage head 14 is mounted on the housing 11 and is connected to a reduction mechanism 13 located inside the housing 11.

[0039] Circuit board 15 is installed inside housing 11 and is electrically connected to transmission mechanism 12 and rechargeable battery 2. Circuit board 15 connects transmission mechanism 12, reduction mechanism 13 and rechargeable battery 2 to realize electrical control and management and ensure equipment safety.

[0040] The specific reduction mechanism 13 consists of a primary gear 131 and a secondary gear 132. The transmission mechanism 12 drives the primary gear 131, while the secondary gear 132 meshes with the primary gear 131, and the secondary gear 132 drives the massage head 14. The combined design of the primary gear 131 and the secondary gear 132 allows the reduction mechanism 13 to achieve effective power transmission within a small space. This structure saves internal space without sacrificing performance, ensuring the compactness and aesthetics of the entire device.

[0041] The specific transmission mechanism 12 is a dual-head motor, with lead screw shafts 121 at both ends. The two lead screw shafts 121 respectively drive a reduction mechanism 13, and the two reduction mechanisms 13 respectively drive a massage head 14.

[0042] The working principle of this invention is as follows: A dual-head motor drives two lead screw shafts 121, which in turn control the movement of the massage head 14 through a reduction mechanism 13, thereby simulating kneading and rotating techniques for massage. A rechargeable battery 2 provides the necessary power, and a circuit board 15 coordinates the operation of all components. The protective structure 3 forms an effective physical barrier, ensuring the battery is not easily damaged and preventing short circuits or accidents. Through the cooperation of these components, the massager achieves an efficient, stable, and comfortable massage effect, and the protective design of the battery and electrical system also improves its safety and reliability.
