Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
It please refers to shown in Fig. 1 and 2, the present embodiment provides a kind of PCB layout structure for tubular motor, mainly for
It is the motor housing 1 of tubular, including shell 11, shaft 12 and PCB2.
Shaft 12 is located at the center of shell 11, and shell 11 is internally provided with installation step 13, and PCB2 is fixed on erecting bed
On rank 13, shaft 12 passes through PCB2, corresponds to shaft 12 on PCB2 and offers relief hole 21, connection jaws 14 are provided on shell 11.
PCB2 includes the top 22 for being located relatively at 21 surrounding of relief hole, the following 23, left side 24 and the right 25, the left side 24, right
The interior shape of 25 corresponding housing 11 of side is set as arc, and top 22 even following 23 is set as the straight flange of non-process.It is existing
PCB be designed as full circle for 11 shape of tubular shell, and when volume production does jigsaw, needs to do layout with square plate, not only makes in this way
At plate significant wastage, also process is carried out to a circle round edge.And in the present embodiment, top 22, following 23 are made into directly
Side, not only does jigsaw conveniently, makes full use of plate, carries out process also without to straight flange, reduces process, reduce production
Cost.
There are three motor down-lead points 26 for distribution on the left side 24, are correspondingly connected with three phase terminal of motor, successively according to upper and lower position
It is divided into U phase point, V phase point and W phase point, a positioning fixed point 27 is provided on the right 25, passes through three motor down-leads
PCB2 is fixed on installation step 13 by point 26 and a positioning fixed point 27, particularly, three motor down-lead points 26 and positioning
Fixed point 27 is welded using pad form and installation step 13, especially single side pad, and PCB2 is facilitated to dismantle.
Herein it should be noted that the installation step 13 of shell 11 is designed as fracture shape, fracture limitation in the present embodiment
Installation site, also increases PCB2 rollover risk, therefore when installing PCB2, is carried out with least fixed point reliably solid
It is fixed.Due to needing to be arranged motor down-lead pad on PCB2 originally, consider three lead pads and fixed point being combined into one
Body, i.e. three motor down-lead points 26, eliminate the fixed point of original three.And the positioning fixed point 27 on the right 25 rises
Main fixation and positioning action, due to the right 25, only one fixes point, and the position of the positioning fixed point 27 is just worthy of careful study, no
Then it be easy to cause rollover, it is preferable that the straight line where positioning fixed point 27 and V phase point passes through the center of relief hole 21, in this way
It can guarantee that the two sides of relief hole 21 are symmetrically fixed, stability is higher.
Supplementary explanation, according to the positional relationship of aforementioned four fixed point, can determine that top 22 must be located at relief hole
It more than 21 middle lines, as to whether being more than 21 top of relief hole, then designs according to actual needs.
Power module 3, control circuit module 4, switch power module 5 and filter capacitor 6, the above member are provided on PCB2
Device is all set in the front PCB2, i.e. plug-in unit face side.Power module 3 is core component, and needs to guarantee heat dissipation effect, too outer
Can all be impacted in too, power module 3 is arranged the present embodiment close to three motor down-lead points 26, and its at least two/
One area is located in the region that positioning fixed point 27 and three motor down-lead points 26 surround, and particularly, power module 3 also is located at
On straight line where positioning fixed point 27 and V phase point, utmostly to guarantee PCB2 overall stability.And power module 3
Foot side is dredged close to three motor down-lead points 26, close foot side can reduce cable run distance close to relief hole 21 in this way, it is dry to reduce electromagnetism
It disturbs.
Connection jaws 14 are provided with several connecting terminals 7 on following 23, switch power module 5 is located at connecting terminal 7
Top, control circuit module 4 are located at the right side of switch power module 5, and filter capacitor 6 is located at power module 3 close to Switching Power Supply
The side of module 5.Each module is arranged such, so that layout comparison is symmetrical, avoids side from assembling more side arrangements and stresses less, and
With good filter effect, electromagnetism interference is good, externally interferes small.
It can be seen that the PCB layout structure has at least the following advantages:
1) PCB surface product reduces, and saves material cost；
2) straight flange conveniently does jigsaw, and does not need workpiece processing, saves processing cost；
3) the fixed point of PCB is few, reduces process operation；
4) the fixed point design of PCB is rationally, fixed reliable；
5) each components' placement is compact, uniform on PCB, and tie line position selection is reasonable；
6) for there is the installation step of fracture port, it also can guarantee reliable installation；
7) heat dissipation effect, filter effect, anti-electromagnetic interference capability are outstanding.
To sum up, the above-mentioned PCB layout structure for tubular motor is from the angle for reducing pcb board area, to PCB's
Fixed point and component above have carried out rational deployment, are guaranteeing installation reliability, component thermal diffusivity, electromagnetism interference
Property etc. under the premise of, farthest reduce PCB size, improve integrated level, to achieve the purpose that reduce cost.
The above embodiments only describe the basic principles and characteristics of the invention, and the invention is not restricted by the above cases,
Without departing from the spirit and scope, the invention also has various changes and changes, and these changes and changes are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
