Description

Brake device for wheels

The invention relates to a brake component which can be driven by electric power to brake the wheel at the wheel of the vehicle, and a grip switch is arranged at the handle of the pusher for the user to perform the pair. The control of whether the wheels are braked or not makes the operation of the brakes of the vehicle easier and less laborious, and also ensures that there is no risk of sliding displacement when the vehicle is at rest.

Vehicles that are generally powered by humans and equipped with wheels, such as M303863, M345015, I513616, etc., are patented for infants and toddlers, with pedals, or pedals, or pushers at the wheels. The handle is equipped with a rotatable twist or a push button to brake the wheel or release the brake through the connected control line. Although the above brake operation is not difficult, the structure is different according to different methods. Each has a difference.

However, regardless of the brakes mentioned above, it is possible to achieve this by relying on manpower, and to brake the wheels of the vehicle or release the brakes, it must be turned back and forth or pressed in different directions. It is also possible to complete the two actions of braking or releasing the brakes. Although it is not difficult or laborious to operate as described above, it is still a traditional manual operation mode, corresponding to the technological age and intelligent operation control. Matching, it is not enough to cope.

In addition, the above-mentioned vehicle, such as a baby carriage, can of course allow the infant car to be smoothly carried out after releasing the brakes of the wheel, but may be caused by the cart when the infant car is stopped. The hand failed to hold the push handle, or parked to forget to brake the wheel, causing the infant car parked on the slope to slide down, causing an unpredictable danger to the infant on the infant car.

The reason is that in order to improve the aforementioned human brake structure of the known vehicle, the inability to cope with the requirements of the intelligent control, and the problem of the inability to control the sliding of the vehicle when it is stationary, the present invention provides a device for mounting a wheel in a wheel base. a brake member driven by an electromagnet and reciprocatingly actuated, and the brake member is provided with an elastically stretchable and insertable into any positioning hole of the side ring of the wheel, so that the wheel can be braked without rotating, and the electromagnet is transmitted through the electromagnet The brake component can be further intelligently controlled, and the carrier can be automatically stopped to prevent slippage when the vehicle is at rest.

The technical solution adopted by the present invention to solve the technical problem is as follows: a wheel base including a wheel coupled to the carrier: the side ring of the wheel is provided with a positioning hole, and a magnet is driven by the position of the wheel seat at the corresponding position. The reciprocating drive rod and the brake member driven by the reciprocating drive rod and having the elastically retractable retaining shaft thereon, and the retaining shaft can be inserted into any positioning hole on the wheel.

In the above solution, the braking component includes a coupling portion disposed on one side of the sleeve and coupled to the reciprocating drive rod, and the retaining shaft is disposed in the sleeve and protrudes.

In the above solution, the carrier is provided with a handle with a grip switch thereon, and the grip switch is electrically connected to the electromagnet through a power source, and the grip switch is controlled by the presence or absence of the grip switch. The retaining shaft on the brake member retreats from the positioning hole or remains inserted into the positioning hole.

Therefore, the brake component that can be braked by the electromagnet can be controlled by the above-mentioned wheel of the present invention, so that the brake operation of the vehicle is not only simplified, but also can cope with wisdom. The need for control can make the brakes of the vehicle more in line with the humanized operation and safety requirements.

Figure 6 is a schematic view of the brake device of the present invention when the wheel is braked.

Figure 7 is a schematic view of the brake device of the present invention when the brake is released to the wheel.

Referring to FIG. 1 and FIG. 2, a wheel 1 is mounted on a wheel base 2, which can be combined with a carrier to allow the vehicle to travel through the wheel 1, and the wheel 1 One side of the wheel 11 is extended, and the same as shown in FIG. 3 and FIG. 4, and on the side of the wheel 1 around the axle 11, the ring is provided with a plurality of spaced positioning holes 12, and the wheel base 2 is provided with a The shaft hole 20 through which the axle 11 can be inserted enables the wheel 11 to be freely rotated by the locking piece 21 inserted into the side of the wheel base 2, so that the wheel 1 can be freely rotated while the inner side of the wheel base 2 is An elastically expandable retaining shaft 42 is extended.

Further, the outer side of the wheel base 2 is covered with a side cover 22, and an electromagnet 3 and a brake member 4 are respectively accommodated in the wheel base 2, wherein the electromagnet 3 is provided with a reciprocating drive that can be driven by electric power. The lever 31, the brake member 4, as shown in FIG. 5, includes a sleeve 41, and a connecting portion 411 is disposed on one side of the sleeve 41 to allow the connecting portion 411 and the reciprocating rod on the electromagnet 3. One end of the 31 is connected together, and a limiting groove 412 is radially opened on the sleeve 41, and a sleeve 41 is bored therein. Extending and passing through the retaining shaft 42 outside the wheel base 2 (as shown in FIG. 2), and a pin 43 is inserted through the limiting slot 412 and is disposed on the inner end of the retaining shaft 42 to allow the retaining shaft 42 When sliding along the axial direction of the sleeve 41, it can only be within the range of the limiting groove 412, and the retaining shaft 42 can be retracted into the sleeve 41, thereby allowing the sleeve 41 to be positioned at the inner end of the retaining shaft 42. A spring 44 is disposed inside, so that the retaining shaft 42 has an elastic expansion and contraction function, that is, the retaining shaft 42 is kept extended by the spring 44, and can be retracted by the external force.

Therefore, as shown in FIG. 6, when the electromagnet 3 causes the reciprocating drive 31 to drive the brake member 4 to retract backward, the retaining shaft 42 on the brake member 4 is retracted from the positioning hole 12 of the wheel 1 to allow the wheel 1 can be freely rotated to enable the carrier to be moved; conversely, as shown in FIG. 7, when the electromagnet 3 causes the reciprocating drive 31 to drive the brake member 4 to move forward, the retaining shaft 42 on the brake member 4 is Inserted into the positioning hole 12 of the wheel 1, or even if the retaining shaft 42 is not aligned with the positioning hole 12 by the side of the wheel 1, but after the wheel 1 is slightly rotated, when the retaining shaft 42 is aligned with the positioning hole 12, When the spring 44 is pushed down and inserted into the positioning hole 12, the wheel 1 is blocked by the retaining shaft 42 and cannot be rotated, thereby achieving the purpose of braking the wheel 1, that is, the carrier cannot move.

Therefore, if the push handle of the pusher handle is mounted with a grip switch that can be grasped by the user, and then electrically connected to the electromagnet 3 through the power source, the electromagnet 3 can make the reciprocating drive 31 to do the back and forth control, that is, let the user grasp the grip switch or the action of the pressure release, let the wheel 1 of the vehicle do the operation control of the brake as described above, so that the operation of the brake can be Control the electrification and meet the needs of intelligent control.

At the same time, the above-mentioned grip switch can be set as a touch switch at a predetermined place on the handlebar, that is, when the user pushes the grip of the vehicle, when the user holds the handlebar, the order will be Release the brake on the wheel 1 so that the vehicle can be smoothly moved; otherwise, when used When the player releases the handlebar, the wheel 1 will be automatically stopped, so that the vehicle can be kept in a static state and the wheel 1 cannot rotate when the vehicle is unattended, so that the vehicle is even It will not slide on the slope, but it will ensure the safety of the vehicle.
