Description

Brushless multifunctional electric tool

Technical Field

The utility model belongs to the technical field of electric tool technique and specifically relates to a brushless multi-functional electric tool is related to.

Background

Some machines in power tools are designed to transmit power and torque with relatively large vibration. For example, electric tool multi-purpose saw adopts the eccentric shaft design, and the motor relies on the bearing on the eccentric shaft to transmit power and moment of torsion, shakes very greatly in the transmission process, and electric tool adopts the battery package as the power supply, and the holistic anti-seismic performance of battery package is not good, and in lasting vibrations process, can lead to the performance to descend and some electronic component damages even, has life weak point, easy problem of shaking out, because the vibration range is big, after using a period, the easy ache of hand.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to overcome the problems that the vibration generated by a motor is large in the prior art, the battery pack is easy to be damaged and the hand is easy to ache after the battery pack is used for a period of time due to large vibration amplitude, a brushless multifunctional electric tool is provided.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a brushless multi-functional electric tool, includes casing, tool bit, is used for providing the motor of power and is used for providing the battery package of the energy for the motor for the tool bit, the tool bit is located the casing front end, the battery package is located the casing rear end, the motor is located the casing, battery package electric connection motor, the output and the tool bit transmission of motor are connected, damper has been arranged between motor and the casing, and the design through damper can weaken vibrations by a wide margin and transmit the casing and transmit to battery package department along the casing from the vibrations source, effectively protects the comfort level of battery package and operator's hand.

In order to solve the problem of damper assembly production installation, further include damper assembly is a plurality of rubber circles, the rubber circle cover is established on the motor, the inner circle wall of rubber circle and the periphery wall contact of motor, the outer circle wall of rubber circle and the inner wall contact of casing, through the design of rubber circle, make damper assembly simple structure, convenient assembling easily makes.

In order to solve the problems of installation of the shock absorption assembly and fixation of the motor, the rubber ring is embedded on the inner wall of the shell, so that the motor is firmly fixed, and the running stability of the motor is improved.

The utility model has the advantages that: the utility model provides a pair of brushless multi-functional electric tool through installing damper between motor and casing, can weaken vibrations by a wide margin and transmit the casing and transmit to battery package department along the casing from the vibration source, effectively protects the fixed comfort level with the improvement operator hand of battery package.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 is a schematic structural diagram of the present invention, a brushless multifunctional electric tool, comprising a housing 1, a tool head 2, a motor 3 for powering the tool head 2, and a battery pack 4 for supplying energy to the motor 3, as shown in fig. 3, the tool bit 2 is located at the front end of the housing 1, the battery pack 4 is located at the rear end of the housing 1, the motor 3 is positioned in the shell 1, the battery pack 4 is electrically connected with the motor 3, the output end of the motor 3 is in transmission connection with the tool head 2, a damping component 5 is arranged between the motor 3 and the shell 1, as shown in figures 2 and 4, by installing the damping assembly 5 between the motor 3 and the housing 1, the vibration transmitted from the vibration source to the housing 1 and transmitted along the housing 1 to the battery pack 4 can be greatly reduced by the design of the damping assembly 5, and the comfort of the battery pack 4 and the hands of an operator can be effectively protected.

As shown in fig. 5, damper 5 is a plurality of rubber rings, and the rubber ring comprises two semicircular flexible glue strips, the rubber ring cover is established on motor 3, the inner circle wall of rubber ring and the periphery wall contact of motor, the periphery wall of rubber ring and the inner wall contact of casing, just the gomphosis of rubber ring is on the inner wall of casing 1, through the design of rubber ring, makes damper 5 simple structure, and convenient assembling easily makes.

During the use, with the rubber circle suit on motor 3, install the motor back in casing 1, fix the tool bit 2 at the front end of casing, at the fixed battery package 4 of rear end gomphosis of casing 1, start at electric tool, at motor 3 moving in-process, the rubber circle can absorb the vibrations that motor 3 produced, effectively protects the fixed comfort level with the improvement operator hand of battery package 4.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
