1. machine boxes, 11. lids, 2. motors, 3. elasticity locating pieces, 4. location-plates, 5. cushions among the figure
The specific embodiment
The drive unit of a kind of lifting type platform as shown in Figure 1 comprises machine box 1, motor 2, and machine box 1 has lid 11, location, the end is provided with the elasticity locating piece 3 of four trough of belt mouths in the machine box 1, particularly, by being fixedly installed on the fin location of bottom, fin embeds elasticity locating piece 4; Four elasticity locating piece 3 subtend settings in twos, each notch is relative; By elasticity locating piece 3 location-plate 4 is set, particularly, location-plate 4 limit portions is snapped in the notch location of each elasticity locating piece 3; Motor 2 is arranged on the location-plate 4, in order to prevent that motor 2 from breakking away on location-plate 4, two projectioies are set on the location-plate 4, then have and protruding corresponding cavity on contacted with it motor 2 casings, the cavity tabling on projection on the location-plate 4 and motor 2 casings; Simultaneously, on location-plate 4, also offer hole or the groove of being convenient to motor radiating; Lid 11 covers machine box 1 its inner face of back and pushes down motor 2, and in order further to improve the vibration damping erasure effect of device, between is provided with cushion 5; Also be provided with fin or the rib that is used for assist location motor 2 and prevents cushion 5 displacements on lid 11 inner faces simultaneously.The surplus space that goes out has the heat radiation chamber of power supply machine 2 heat radiations of one's own in the machine box 1.
The present invention also has some other embodiment for the location of its elasticity locating piece 3 or location-plate 4.Elasticity locating piece 3 is fixing by the fin intercalation of machine box 1 bottom in the above-described embodiments, and location-plate 4 adopts groove to connect mode with elasticity locating piece 3.An alternative embodiment of the invention is: also can pass through in its machine box 1 bottom opening, elasticity locating piece 3 is made after supporting size and the shape and the location of pegging graft, hole, do suspension column in the corresponding position of location-plate 4 then, insert elasticity locating piece 3 with location location-plate 4.As Fig. 3, the structural representation of embodiment for this reason.
The drive unit of electric lifting desktop, its operation principle are that rotatablely moving of motor is converted into moving up and down of push rod by worm and gear, thereby realize the lifting of desktop.This drive unit is a kind of instantaneous power set that run up, and rotating speed of motor is higher during work, can produce stronger vibration and noise, and motor can give out more heat, and therefore the project organization for drive unit has certain requirement.Undoubtedly, this type of more outstanding drive unit should have the favorable damping performance on structural design, low noise, and to guarantee that work drive motor can dispel the heat well, because this directly has influence on the continuous working period and the working life of motor.
Characteristics of the present invention promptly are both to have made and work drive motor can be dispelled the heat the low low noise that shakes of whole drive unit well, prolong its working life.
Mentality of designing of the present invention is to guarantee that motor located by flexibility and have on the basis of good result, vacateing the space of power supply machine heat radiation as much as possible.For cooperating this Design of device structure, aspect the making material that uses, can adopt rubber, noise reduction cotton, polyurethane foam or other flexible materials to make in order to the cushion that is provided with between the elasticity locating piece of flexible positioning motor and machine lid and the motor in the utility model, location-plate can adopt plastic or other material to make, with the vibration damping erasure effect of further raising device.
The specific embodiment based on mentality of designing of the present invention may be multiple in addition; generally be to the elasticity locating piece that is used for positioning motor, location-plate, cushion etc. shape, position, quantity or fixed form be set slightly do change; but overall project organization is the same, and these concrete embodiments all should be within the scope of protection of present invention.
