Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.Specific embodiment described herein is used only for explaining that this practicality is new
Type is not used to limit the utility model.
The purpose of this utility model is that the movement for more transmission shaft of being controlled the size using the motor of negligible amounts, with
This realization is laid out in smaller space.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, a kind of transmission device, including first motor 1
It is connected with worm screw 3 with the output shaft of the second motor 2, the first motor, the worm screw 3 coordinates with worm gear 4, the worm gear 4
Several cams 5 are provided in rotation axis 41, the outer diameter of the cam 5 designs for mutation formula, and is installed on institute with different angle
It states in rotation axis 41.Further include sliding block 6, one end of the sliding block is first gear 61, and other end is transmission shaft 62, the biography
Moving axis connects external antenna, and the angle of antenna can be adjusted.When 61 stress of first gear rotates, can drive
Transmission shaft rotates, to realize the transmission of power.
The mode of Worm Wheel System, can obtain prodigious reduction ratio, i.e. many circles of worm screw rotation could drive worm gear
One circle of rotation, reduces rotating speed, can obtain big torque, torque is bigger, and driving capability is stronger.Worm and gear has self-locking performance,
Can only single-direction transmission, cam can be effectively prevent to rotate backward.
It is gear set 7 with 61 cooperating of first gear, there is several second gears 71, second tooth on gear set 7
Wheel 71 can drive first gear 61 to rotate.When cam 5 is rotated with rotation axis 41, since the outer diameter of cam 5 is mutation formula
Design, when the point of cam largest outside diameter, i.e., when the far point 51 of cam is contacted with sliding block 6, cam 5 pushes sliding block 6, makes first gear
61 engage with second gear 71, the two cooperating；As cam 5 continues to rotate, sliding block 6 loses the support of cam far point, by
Original position is retracted in the effect of first elastic element 63.
The output end of second motor 2 is third gear 21, and third gear 21 drives second gear 71 to rotate, second gear 71
First gear 61 is driven to rotate, first gear 61 drives transmission shaft 62 to rotate, to realize the adjusting to external aerial angle.
Technical solution described above is still a scheme more summarized, and the thinking of core is that first motor 1 is responsible for
Transmission shaft 62 to be regulated is sent to specified position, the second motor 2 is responsible for specific adjust；Simultaneously because cam 5 and gear
The design of group 7, may be implemented the adjusting of multiple transmission shafts.
The utility model more preferably technical solution is described below.
The preferred melon seeds shape of structure of cam 5, outer diameter are apparent mutation formula designs, and the point farthest apart from the cam center of circle is
Far point 51；When far point 51 is no and sliding block 6 contacts, first gear 61 can not touch second gear 71, at this point, no matter
How gear set 7 rotates, and can not all deliver torque to first gear 61, also transmission shaft can not be driven to adjust under antenna
Inclination angle.
Only when far point 51 is contacted with sliding block 6, first gear 61 could be contacted with second gear 71.Sliding block 6 is solid at one
Moved in fixed slideway 64, when far point 51 with rotation axis 41 rotate far from sliding block 6 when, therefore, to assure that sliding block 6 can restore to
Original position, therefore, it is necessary to first elastic element 63 is arranged on sliding block 6.Meanwhile sliding block 6 is retracting original in order to prevent
It after having position, swings in a certain range, the bottom of sliding block is provided with self-locking device 65, the self-locking device 65 includes setting
The first groove 651 on shell 8, is set to the hole 652 of slider bottom, the second elastic element being set in hole 652
653, the outside of the second elastic element 653 is fixed with the first steel ball 654, and the cooperation of first steel ball, 654 and first groove 651 is solid
It is fixed.When sliding block 6 retracts original position, due to the effect of the first elastic element 63, often continue to move in the opposite direction,
And repeatedly.The effect of the self-locking device 65 is exactly the tendency for overcoming above-mentioned sliding block to move round about.
Three cams 5 are at least set in rotation axis 41, each cam 5 corresponds to a sliding block 6, and corresponding second tooth
Wheel 71.Setting is needed to have a certain degree between cam 5, this angle can be designed as identical angle, may be designed in
Different angles.Either any design scheme, what the angle between cam 5 should be to determine, such first motor 1 is in band
After dynamic worm screw rotates by a certain angle, it may be determined that the relative position of each cam 5 and sliding block 6.In addition it is additionally provided between sliding block 6
Interlock 66, the interlock 66 include the second groove 663 being arranged in 64 both sides of slideway, the through-hole being set on sliding block
664, the interlocking plunger 661 and the second steel ball 662 being set in through-hole 664.Above-mentioned design ensures first gear 61 on sliding block 6
It will not occur to wear and damage caused by reciprocating collision between the second gear 71 on gear set 7, ensure that can only once control
Make a transmission shaft 62.
The second gear 61 being connect with transmission shaft 62 is axial non-rigid, and second gear 61 is made with 62 axial direction of transmission shaft
Positive and negative 5 ° or so of small size rotation is touched with solving conical gear tooth present in mobile engagement process in slide assemblies with tooth
It hits, push up wound, stuck problem.
The utility model can be whole setting in a shell 8, power supply and control module 9 are additionally provided in shell 8,
Interface module 81 is provided on shell 8, to realize that the plug-in of the utility model uses.The utility model patent whole device collection
