Specific embodiment
The utility model discloses a kind of shopping cart brake gears being installed on shopping cart wheel, below with reference to preferred reality
Example is applied, specific embodiment of the present utility model is further described.
The shopping cart brake gear of the utility model, including outer cover 10 and protection cap 20, outer cover 10 and protection cap 20 pass through
Screw is fixed, and is equipped with motor 11 in outer cover 10 and is fixed with the brake shoes 17 of magnetic stripe 173, motor 11 and the first battery 12, first
Magnetic switch 13 and the second magnetic switch 14 are sequentially connected electrically to form the first series loop, motor 11 also with the second battery 15,
Three magnetic switch 16 are sequentially connected electrically to form the second series loop, and wherein motor 11 is in the first series loop and the second series loop
Middle positive and negative anodes connect on the contrary, the driving gear 111 of motor 11 is engaged with the rack gear 171 that 17 upper end of brake shoes is equipped with driving brake
Block 17 moves up and down.
Specifically, referring to Figure 1 of the drawings, Fig. 2 and Fig. 3, it is whole that Fig. 1, Fig. 2 and Fig. 3 respectively illustrate the utility model
The right view structure of stereochemical structure, the structure of the protection cap of the utility model and the utility model, 20 bottom of protection cap have
For opening 22 for passing through when brake shoes up and down motion, shopping cart brake gear 1, which has, runs through outer cover 10, protection cap 20 and brake shoes
The fixation hole 21 of movable span 172 is shopping cart brake gear to be fixed on wheel.
The internal structure of the utility model is shown referring to Fig. 4 of attached drawing, Fig. 4, is fixedly installed with motor on the inside of outer cover 10
11 and brake shoes 17, motor 11 has a driving gear 111, and 17 upper end of brake shoes is equipped with the driving gear 111 with motor 11
The rack gear 171 being meshed, motor 11 can make that gear 111 is driven to rotate when working, to pass through 171 band of rack gear on brake shoes 17
Dynamic brake shoes 17 moves up and down, and lays the first battery 12 and the second battery 15, the first battery respectively in the two sides of brake shoes 17
The first magnetic switch 13 is also placed between 12 and brake shoes 17, brake shoes 17 is laid on the position of the first magnetic switch 13
Magnetic stripe 173, brake shoes 17 be in the initial state positioned at can up and down region top, magnetic stripe 173 and the first magnetic force at this time
The distance of switch 13 is close, and the first magnetic switch 13 is in closed state, the second magnetic switch 14 peace under the action of magnetic stripe 173
It is placed on the bottom of outer cover 10, normally open is under no external magnetic force disturbed condition, third magnetic switch 16 is placed in second
By the other side of battery 15, third magnetic switch 16 is also at normally open in the case where no external magnetic force intervenes.
The circuit connection of the utility model, motor 11 and the first battery 12, the first magnetic are shown referring to Fig. 5 of attached drawing, Fig. 5
Power switch 13 and the second magnetic switch 14 are sequentially connected electrically to form the first series loop, motor 11 also with the second battery 15, third
Magnetic switch 16 is sequentially connected electrically to form the second series loop, wherein in the first series loop the positive and negative anodes of motor 11 respectively with
The anode of first battery 12 and one end of the second magnetic switch 14 are electrically connected, the positive and negative anodes of motor 11 point in the second series loop
It is not electrically connected with one end of the cathode of the second battery 15 and third magnetic switch 16.
Further, in the state of doing shopping 3 normally travel of wheel, the first magnetic switch 13 is in closure from the above
State, and since shopping cart is travelled on common ground, so the second magnetic switch 14 is not due to by magnetic force
Effect is also at the state of disconnection due to not interfered by external magnetic force in the state disconnected, third magnetic switch 16,
So the first series loop and the second series loop are off-state, motor in shopping wheel 3 in the state of normally travel
11 be it is inoperative, do not influence shopping cart normally travel.
Further, the inside that shopping brake gear 1 is matched with wheel 3 of doing shopping is shown referring to Fig. 7 of attached drawing, Fig. 7
Structure is laid with magnet on ground at the shopping cart recycling, and recovery area is pushed into after shopping cart is finished, is placed in 10 bottom of outer cover
The second magnetic switch 14 by the magnet on ground effect and be closed, the first series loop at this time formed conducting circuit,
The operating of motor 11 drives driving gear 111 to rotate, so that the rack gear 171 on driving brake block 17 drives 17 pieces of brake fortune downwards
Dynamic, brake shoes 17 passes through the insertion shopping inner preset groove 31 of wheel 3 of opening 22 of 20 bottom of protection cap, meanwhile, brake shoes 17
The upper magnetic stripe 171 close to the first magnetic switch 13 is also driven far from the first magnetic switch 13, when brake shoes 17 reaches shopping cart
When taking turns 3 inner preset groove 31, magnetic stripe 173 makes its magnetic force to the first magnetic switch 13 at a distance from the first magnetic switch 13
It influences to disappear, the first magnetic switch 13 disconnects, and the first series loop disconnects, and motor 11 shuts down.
Further, when needing to reuse shopping cart, staff need to only take one block of magnet to third magnetic switch
16 can be realized unlock, specifically, third magnetic switch 16 by magnetic force effect and be closed, the second series loop is led at this time
It is logical, but due to motor 11 in the second series loop with connect in the first series loop on the contrary, so motor 11 drives and stops at this time
Vehicle block 17 leaves the shopping inner preset groove 31 of wheel 3, returns to initial position, the magnet that staff uses leaves third magnetic force
I.e. so that the second series loop disconnects, motor 11 shuts down switch 16, and shopping cart restores normal ability to act.
Referring to attached drawing 6 and Fig. 8, Fig. 6 and Fig. 8 show the external knot that shopping cart brake gear 1 is matched with wheel 3 of doing shopping
Shopping cart brake gear 1 need to be only mounted on shopping wheel 3 by structure by fixing bolt.
For a person skilled in the art, technical solution documented by foregoing embodiments can still be repaired
Change or equivalent replacement of some of the technical features, it is within the spirit and principle of the utility model, made any
Modification, equivalent replacement, improvement etc., should be included in the protection scope of the utility model.
