Description

Modular motor transmission device

Technical Field

The invention relates to the technical field of massage devices, in particular to a modularized motor transmission device.

Background

In products with telescopic motion output function (such as human body massagers, fascial guns, electric cleaning brushes, etc.), there are usually a series of power supply and power transmission devices such as motors, speed reducers, reversing devices, etc., which work together to achieve the telescopic or push-pull motion required by the products, and these devices are collectively called as telescopic power structures. The telescopic motion component at the tail end of the telescopic power structure is connected with a product output end capable of acting on a product object (such as a human body, sanitary ware and the like), namely, a complete product structure is formed, and the product output end can be a spherical rubber-coated gun head of a fascia gun, or a brush head of an electric cleaning brush and the like. The telescopic power structure and the product output end are generally in a linear arrangement layout, namely, a telescopic motion path output by the telescopic power structure and a motion path of the product output end are positioned on the same straight line or approximately on the same straight line, and the telescopic power structure is visually similar to the telescopic power structure in the shape of pushing and pulling the product output end behind to complete power transmission.

In products with telescopic motion output as a main function, namely the telescopic power structure, the battery and the circuit control board are used as main internal components of the products, and due to the difference of research and development technical levels of brand parties and production parties of various products, a large number of products with similar industrial design styles, similar internal components and structures, but good product performance and product quality are not uniform exist in the market.

The above-mentioned defective products often have the following design defects:

1. the size is not compact. Due to the constraint of structural design capacity, the spatial layout of structural parts is unreasonable, the product size is large but the performance is not improved, and great loss is brought to the aspects of attractiveness, material cost and assembly cost.

2. The performance is insufficient. Because the design contents of a plurality of electromechanical integration directions such as electromotion, transmission, circuit driving, software control and the like are involved, the product performance is insufficient due to the constraint of the system design capability or the single design capability, and the system is embodied in small output kinetic energy, low transmission efficiency, high noise, poor heat dissipation, easy abrasion of components, low energy conversion rate, poor circuit driving capability, poor software control precision and the like.

3. The production cost is high. Although the products belong to the same type, the production processing method and the assembly mode are inconsistent due to independent design style, component selection, structural characteristics and the like, and the processing and assembly mode of each product needs to be defined independently, so that the time and the energy are consumed.

Compared with the prior art, the invention has the beneficial effects that:

first, the present invention has a uniform technical standard, and the establishment of the uniform technical standard is an important mark for the transition of the industry from the initial stage of wild growth to the mature period of the industry with larger scale development. For consumer products which are on the market and have a main function of telescopic power, the technical characteristics of the consumer products are obviously still in the initial stage of industry, and the selection and matching of internal components have no industrial standard. The modularized motor transmission device introduces a set of unified technical standard, namely, the unified deconstruction of all products of the same type is a product shell and the modularized motor transmission device.

Secondly, the invention has the characteristic of synchronous iteration, aiming at a large number of product brands or product producers which lack product research and development ability, the modularized motor transmission device is selected to replace the original internal components of the product, and the product iteration can be realized immediately on the premise of not requiring additional research and development ability; aiming at the products of the selected modularized motor transmission device, any subsequent design change iteration occurs in the device, and the iteration characteristic of the device can be quickly deployed to all products adopting the modularized design scheme.

Thirdly, the energy efficiency of the invention is higher, and the design scheme that all the related components are assembled in the shell and the inner layer guard plate enables the modularized motor transmission device to have higher energy efficiency than the traditional design scheme that the components in the product are separated, and particularly, the power component (such as a motor), the transmission component (such as a gear and a crankshaft), the electric energy supply component (such as a battery), the electric energy control component (such as a circuit board) and other related components are compactly positioned in the same main frame, so that the mechanical energy transmission efficiency, the electric energy and mechanical energy conversion efficiency and the electric energy transmission efficiency are effectively improved.

Fourthly, the reliability of the invention is higher, and the improvement of the reliability comes from two aspects, one is that the loss is reduced by the modularized design method, and the loss is embodied in the transmission resistance, the transmission noise and the like caused by the unreasonable power transmission path and the capacity imbalance among the transmission assembly, the power assembly and the electric energy assembly caused by the unreasonable system design. Secondly, because of the beneficial effect of the synchronous iteration, all products adopting the modularized motor transmission device naturally become test samples of the technical standard, namely, the synchronous iteration characteristic brings the synchronous test verification characteristic, and the reliability guarantee that the main body is tested and verified by the market is brought to newly developed products.

And fifthly, the invention has lower cost, and the cost reduction comes from three aspects, wherein in the first aspect, the modularized design method reduces the total material loss. Secondly, the design method of the module main frame improves the structural strength, so under the requirement of equivalent performance indexes, the material requirement can be reduced, for example, in the traditional design scheme of the separated components in the product, the speed reducer usually adopts a metal shell to achieve the expected transmission efficiency, and in the modular design scheme, because the shells of all the components are equivalent to the same main frame, the main frame can adopt an engineering plastic scheme with the obviously reduced cost. Thirdly, a large number of products reuse the same or similar modular devices, and the large-scale production can directly reduce the production cost of the modular devices, particularly the production cost of all components (batteries, motors, structural members, circuit boards and the like) selected in the modular devices.

In the device, all related components such as a power component (such as a motor 11), a transmission component (such as a gear and a crankshaft 9), an electric energy supply component (such as a battery 4), an electric energy control component (such as a circuit control panel 3) and the like are compactly positioned in the same main frame, so that the mechanical energy transmission efficiency, the electric energy and mechanical energy conversion efficiency and the electric energy transmission efficiency can be effectively improved.

Specifically, a main frame 13 is bolted to the bottom surface of the housing 1, the main frame 13 is wrapped on the surfaces of the housing 1 and the massage head 12, a half of the massage head 12 is exposed outside the main frame 13, a cushion pad 14 is bonded to the inner side edge of the main frame 13, and the cushion pad 14 is made of sponge.

For the first embodiment of fig. 3-6, the working principle is as follows:

in this embodiment, the reduction device 10 is a worm-and-gear reduction structure, specifically, a helical worm is mounted on the output shaft of the motor 11, and then one or more gears are meshed with each other, and the gears are meshed with each other step by step to realize the effect of reducing the rotation speed. The worm in the worm and gear type speed reducing structure can be helical gear lines or straight gear lines, the gear or gear set effect can be that the output rotating shaft of the parallel output shaft is parallel to or coincident with the input rotating shaft or is a right-angle output shaft, namely a figure, and the direction of the output rotating shaft is vertical to the direction of the input rotating shaft.

The reduction gear unit 10 may also be implemented in other ways, such as a gearbox reduction gear unit 10.

The reversing device adopts a structure of a crankshaft 9 and a connecting rod 8 to realize the effect of converting rotary motion into linear telescopic push-pull motion. Both the crankshaft 9 and the connecting rod 8 are transmissions with double fixed ends. The crankshaft 9 includes a fixed end a and a pin positioning end B, and the connecting rod 8 includes a pin positioning end a and a pin positioning end B. The fixed end A of the crankshaft 9 is fixed with the output end of the speed reducer 10, and the crankshaft 9 and the output mechanism of the speed reducer 10 are guaranteed not to move relatively between final-stage gears, namely the output end of the speed reducer 10 drives the crankshaft 9 to rotate at an equal angular velocity through the fixed end A of the crankshaft 9, so that the pin positioning end B of the crankshaft 9 performs circular motion at an equal angular velocity around the fixed end A of the crankshaft 9, and the motion radius is the distance between the fixed end A of the crankshaft 9 and the pin positioning end B of the crankshaft 9. The pin positioning end B of the crankshaft 9 and the pin positioning end A of the connecting rod 8 are fixed in a pin mode, and a bearing 103 or a sliding limiting hole and the like can be specifically adopted. For example, when the bearing 103 is used for fixing, the pin positioning end B of the crankshaft 9 drives the axis of the pin positioning end A of the connecting rod 8 to do circular motion with the same track and the same angular velocity, but the connecting rod 8 can still do rotary motion around the axis of the pin positioning end A of the connecting rod 8. For example, the crankshaft 9 pin positioning end B is fixed by a sliding limit hole, that is, the crankshaft is designed as a guide groove, so that the axis of the connecting rod 8 pin positioning end a can slide in a path limited by the guide groove, and the connecting rod 8 can still rotate around the axis of the connecting rod 8 pin positioning end a. The two examples have the effect that the distance between the axis of the pin positioning end A of the connecting rod 8 and the fixed end A of the crankshaft 9, namely the rotating radius, is variable during the movement. The shaft sleeve assembly 7 comprises a pin positioning end, a shaft sleeve, an output hanging point and the like, and the above components can be integrally formed, namely the shaft sleeve assembly 7 is a machined part, or can be assembled by a plurality of machined parts. The connecting rod 8 pin positioning end B and the shaft sleeve assembly 7 are also fixed in a pin mode, the specific embodiment is similar to the upper section, and the realization effect is that the relative position between the axis of the connecting rod 8 pin positioning end B and the shaft sleeve assembly 7 is unchanged or the relative displacement is limited depending on the mode of the shaft sleeve pin positioning end, but the connecting rod 8 can still rotate relative to the axis of the connecting rod 8 pin positioning end B. The shaft sleeve part of the shaft sleeve component 7 is sleeved on the limiting shaft 6, the limiting shaft and the limiting shaft can slide linearly relatively in a piston motion mode, the limiting shaft 6 is fixed on a keel or a shell 1 and the like on the main structure of the product, and the motor 11, the battery 4, the circuit board and the like are static parts relative to the main structure of the product. The shaft sleeve assembly 7 can realize linear telescopic push-pull motion under the driving of the connecting rod 8 due to the limitation of the motion path of the linear piston. An output hanging point of the shaft sleeve assembly 7 is fixed with the output end of the product, and the output end of the product is driven to do corresponding linear telescopic push-pull motion. The output hanging point and the product output end are assembled and fixed, and then the product output end, the power assembly motor 11, the speed reducer 10 and the reversing device form a parallel relation instead of a linear layout relation, namely, the upper-lower relation of the figure is not the left-right relation.

Aiming at the working principle of the second embodiment of the figures 1-2:

in this embodiment, the product is easy to hold, and the whole product is integrated in the same main frame 13 module, so that the product conforms to the operating rule of a human body when in use.

When in use, a user can hold the handle 15, the antiskid pad 14 on the inner side of the handle can prevent the product from slipping, when in use, the battery 4 supplies power to the circuit control panel 3, the motor 4 is started and sequentially passes through the driving gear 105, the straight gear 104 and the transmission gear 102, the crankshaft 9 and the connecting rod 8 drive the shaft sleeve assembly 7, thereby controlling the massage head 12 to vibrate, the massage head 12 is tightly attached to the position to be massaged, the human body is massaged, the whole set of device is integrated in the main frame 13, the vibration of the massage head 12 is buffered by the buffer pad 14, the vibration of the main frame 13 cannot be caused, and therefore, the massage device is simple and convenient for massaging the human body.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
