Abstract
The utility model discloses a waterproof DC (Direct Current) brushless speed reduction motor used for a baby stroller, and is characterized by comprising a brushless motor, a transmission shaft and a planetary reducer; wherein the transmission shaft is connected with the brushless motor through the planetary reducer; the brushless motor comprises a first casing; the first casing is provided with a front end cover and a rear end cover; both the front end cover and the rear end cover are in sealed connection with the first casing. The waterproof DC brushless speed reduction motor used for the baby stroller provided by the utility model has a good sealing performance, and can prevent water of the outside world from seeping in the motor to corrode an internal structure of the motor, especially, the waterproof DC brushless speed reduction motor can prevent rainwater of the outside world from corroding electronic components such as the brushless motor, the planetary reducer, a driver, and a circuit board; in addition, by adopting the waterproof DC brushless speed reduction motor, the baby stroller can be used without being limited by a rainy day, thus the baby stroller has a long service life.
Description
Technical field
The utility model relates to a kind of doll carriage waterproof brushless DC speed reduction motor.
Background technology
Doll carriage is subject to the restriction of volume and outward appearance, need to be placed on motor and driver together in the trailing wheel pipeline.Rainy day, extraneous rainwater will immerse wiring board and the electronic devices and components of pipeline corrosion motor, planetary reduction gear, driver when outdoor application.Both limit the use of doll carriage, shortened again the useful life of motor.
The utility model content
One of the purpose of this utility model is in order to overcome deficiency of the prior art, a kind of doll carriage waterproof brushless DC speed reduction motor that prevents extraneous water erosion to be provided.
For realizing above purpose, the utility model is achieved through the following technical solutions:
Doll carriage waterproof brushless DC speed reduction motor is characterized in that, brushless electric machine, power transmission shaft and planetary reduction gear; Power transmission shaft is connected with brushless electric machine by planetary reduction gear; Brushless electric machine comprises the first casing; Described the first casing is provided with the first front end housing and rear end cap; Front end housing all is connected with the first casing sealing with rear end cap.
Preferably, described planetary reduction gear comprises the second casing; Described power transmission shaft is inserted in the second casing rotationally; Described the second casing is provided with the second front end housing; Be provided with O type circle between described power transmission shaft and the second front end housing.
Preferably, also comprise the 3rd shell, driver is arranged in the 3rd shell; The 3rd shell is connected in the first outer casing back by sealant sealing.
Preferably, driver passes through the fluid sealant can in the 3rd shell.
Doll carriage in the utility model waterproof brushless DC speed reduction motor, good seal performance, can prevent that extraneous water from immersing and the corrosion electrical motor internal structure, especially can prevent extraneous rainwater corrosion brushless electric machine, planetary reduction gear and the electronic devices and components such as driver and circuit board.Go-cart is used and not limited by the rainy day, long service life.
Description of drawings
Fig. 1 is the utility model structure chart.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1, doll carriage waterproof brushless DC speed reduction motor, brushless electric machine, power transmission shaft 1 and planetary reduction gear.Power transmission shaft 1 is connected with brushless electric machine by planetary reduction gear.Brushless electric machine comprises the first casing 6.The first casing 6 is provided with the first front end housing 5 and rear end cap 7; The first front end housing 5 all is tightly connected with the first casing 6 with rear end cap 7.Planetary reduction gear comprises the second casing 4.Power transmission shaft 1 is inserted in the second casing 4 rotationally.The second casing 4 is provided with the second front end housing 2.Be provided with O type circle 3 between power transmission shaft 1 and the second front end housing 2.Also comprise the 3rd shell 9, driver 10 is arranged at the 3rd shell interior 9; The 3rd shell 9 is sealedly attached to the first shell 6 rear ends by fluid sealant 8.Driver 10 passes through fluid sealant 8 cans in the 3rd shell 9
