Referring to fig. 1 to fig. 6, a head assembly 100 is provided for one embodiment of the present invention, the head assembly 100 can be applied to an electric door such as an electric retractable door, an electric side hung door, etc., and in this embodiment, the application of the head assembly to the electric retractable door is taken as an example for detailed description.
The machine head assembly 100 is used for being connected with a door body of the electric door, and the machine head assembly 100 can move along the horizontal transverse direction x so as to pull the door body of the electric door to move along the horizontal transverse direction x.
The head assembly 100 includes a base assembly 10, a first wheel 20, a second wheel 30, a wheel drive device 40, and a brake device 50, wherein the wheel drive device 40 is shown in fig. 2 and the brake device 50 is shown in fig. 5. The base assembly 10 is used for connecting the electric retractable door. The first wheel 20 and the second wheel 30 are respectively mounted at two ends of the base assembly 10 along a horizontal direction x, as shown in fig. 1. Both the first wheel 20 and the second wheel 30 are rotatable relative to the base assembly 10 about a horizontal longitudinal direction y to move the base assembly 10 in a horizontal transverse direction x. The wheel drive device 40 is mounted to the base assembly 10 and is connected to the first wheel 20 for driving the first wheel 20 to rotate about the horizontal longitudinal direction y relative to the base assembly 10.
The brake device 50 and the second wheel 30 are both mounted to the same end of the base assembly 10. The brake device 50 is disengaged from the second wheel 30 when the first wheel 20 and the second wheel 30 together support the base assembly 10 at a horizontal plane p. When the second wheel 30 supports the base assembly 10 at a horizontal plane p and the first wheel 20 is spaced a predetermined distance d from the horizontal plane p, the brake device 50 abuts the second wheel 30 to block the second wheel 30 from rotating, as shown in fig. 4 and 5.

By providing the wheel drive device 40 only for driving the first wheel 20 to rotate, and avoiding the connection of the second wheel 30 through an adapter component, a two-wheel driven handpiece assembly 100 is realized, wherein the handpiece assembly 100 has low cost and short assembly time.
In addition, by configuring the wheel driving device 40 for driving the first wheel 20 to rotate and the braking device 50, when the end of the base assembly 10 where the first wheel 20 is installed is lifted, that is, when the first wheel 20 is spaced from the horizontal plane p by the preset distance d, the braking device 50 abuts against the second wheel 30 to block the second wheel 20 from rotating, a handpiece assembly 100 adopting a two-wheel driving method is realized, and when the end of the handpiece assembly 100 where a driving wheel (i.e., the first wheel 20) is installed is lifted, the handpiece assembly 100 cannot be manually pushed.
While specific implementations of handpiece assembly 100 are described below, it should be noted that the following is merely exemplary and that other handpiece assemblies 100 capable of satisfying at least one of the above conditions are within the scope of the present application.

The second wheel 30 is mounted to the mounting arm 16 to be rotatable about a horizontal longitudinal direction y relative to the mounting arm 16. The braking device 50 is mounted to the wheel frame 14.
When the first wheel 20 and the second wheel 30 jointly support the base assembly 10 at the horizontal plane p, the wheel frame 14 and the base 12 swing to the first position to separate the braking device 50 from the second wheel 30.
When the second wheel 30 supports the base assembly 10 at a horizontal plane p and the first wheel 20 is spaced a predetermined distance d from the horizontal plane p, as shown in fig. 4 and 5, the wheel frame 14 and the base 12 swing to the second position such that the braking device 50 abuts against the second wheel 30.
Referring to fig. 1, 2 and 3, the base 12 is a box-shaped structure with a vertical and horizontal structure, and a stand 120 is disposed on a side of the base 12 away from the horizontal plane p. The two stands 120 are opposed in the horizontal longitudinal direction y.
The two first wheels 20 are both mounted on the base 12 near the horizontal plane p and are respectively located on both sides of the base 12 along the horizontal longitudinal direction y. A transmission shaft 22 penetrates the base 12 along the horizontal longitudinal direction y, and the two first wheels 20 are respectively installed at two ends of the transmission shaft 22, so that the two first wheels 20 can synchronously rotate. The middle of the transmission shaft 22 is provided with a first sprocket (not shown) coaxial therewith, and the two first sprockets are separated in the horizontal longitudinal direction. The two vertical frames 120 are respectively provided with a second chain wheel 122 rotating around the horizontal direction, and the second chain wheel 122 and a corresponding first chain wheel mounted on each vertical frame 120 are sleeved on an annular chain 124. The driving device 40 is mounted on one of the two brackets 120, and is connected to the second chain wheel 122 on the bracket 120, and is configured to drive the second chain wheel 122 connected thereto to rotate.
In some embodiments, the driving device 40 is an electric motor, and the driving device 40 may also be a pneumatic motor, a hydraulic driving system, or the like.
Referring to fig. 1, 3 and 4, the wheel frame 14 is a box-shaped structure with a horizontal type overall, one end of the wheel frame 14 along the horizontal direction x is mounted on the base 12, and the braking device 50 is mounted on the other end of the wheel frame 14 along the horizontal direction x and is located on one side of the wheel frame 14 facing the horizontal plane p. The middle part of the wheel carrier 14 extends to a cantilever 142 towards the direction of the horizontal plane p, the two cantilevers 142 are opposite along the horizontal longitudinal direction y, and a fixed shaft 140 extending along the horizontal longitudinal direction y is installed between the two cantilevers 142. The mounting arm 16 is mounted to the fixed shaft 140, and the mounting arm 16 is swingable about the fixed shaft 140 with respect to the wheel frame 14.

Referring to fig. 2 and 3, the longitudinal dimension of the wheel frame 14 is smaller than the longitudinal dimension of the base 12, and the wheel frame 14 is installed at the middle of the base 12 along the horizontal longitudinal direction y. According to practical situations, the wheel frames 14 can also be provided in two, and in other embodiments, the two wheel frames 14 are opposite to each other along the horizontal longitudinal direction y and are respectively installed at two ends of the base 12 along the horizontal longitudinal direction y.
Referring to fig. 5, the braking device 50 is a bump integrally formed with the wheel frame 14, and the bump may be replaced by a friction plate or a friction bar according to practical situations.
Referring to fig. 1 and 4, one end of the mounting arm 16 is close to the base 12, and the other end of the mounting arm 16 is far from the base 12. At least one of the second wheels 30 is mounted to each end of the mounting arm 16. The middle of the mounting arm 16 is mounted to the fixed shaft 140. By mounting at least one of the second wheels 30 at each end of the mounting arm 16, and mounting the middle portion of the mounting arm 16 to the fixed axle 140, the second wheels 30 mounted at each end of the mounting arm 16 can support the base assembly 10 at the same level p regardless of whether the mounting arm 16 is swung to the first position or the second position relative to the base 12. When the mounting arm 16 is swung to the second position, the second wheel 20 mounted on the end of the mounting arm 16 remote from the base 12 abuts the brake 50.
Referring to fig. 3, the total number of the second wheels 30 mounted at both ends of the mounting arm 16 is four. Of the four second wheels 30, two are respectively installed on two sides of one end of the installation arm 16 along the horizontal longitudinal direction y, and the remaining two are respectively installed on two sides of the other end of the installation arm 16 along the horizontal longitudinal direction y. Any three of the four second wheels 30 may form a triangular support structure on the horizontal plane p, so that when the mounting arm 16 swings to the second position, the stability of the base assembly 10 is ensured and the base assembly is not prone to toppling.
Referring to fig. 3 and 6, the mounting arm 16 includes a side arm 160, a first connecting shaft 162, a second connecting shaft 164, a first bearing 166, a second bearing 168 and a third bearing 169. The side arms 160 are in a strip-like configuration extending along a horizontal transverse direction x, one end of the side arm 160 is close to the base 12, and the other end of the side arm 160 is far away from the base 12. The number of the side arms 160 is two, and the two side arms 160 are opposite to each other along the horizontal longitudinal direction y.
The first connecting shaft 162 extends along the horizontal direction y, and the first bearing 166 is sleeved between two ends of the first connecting shaft 162. The number of the first bearings 166 is two, and the two first bearings 166 are spaced apart along the horizontal direction y, and are respectively provided for one end of the two side arms 160 close to the base 12 to be sleeved. The second connecting shaft 164 extends along the horizontal longitudinal direction y, and the second bearing 168 is sleeved between two ends of the second connecting shaft 164. The number of the second bearings 168 is two, and the two second bearings 168 are spaced apart along the horizontal direction y and are respectively provided for sleeving one end of the two side arms 160 away from the base 12. Of the four second wheels 30, two are respectively mounted to both ends of the first connecting shaft 162, and the remaining two are mounted to both ends of the second connecting shaft 164. The first connecting shaft 162 and the second connecting shaft 164 are circumferentially fixed to the second wheel 30 by flat keys. The third bearing 169 is sleeved between the two ends of the fixing shaft 140. The number of the third bearings 169 is two, and the two third bearings 169 are opposite to each other along the horizontal longitudinal direction y and are respectively sleeved by the two side arms 160.
It is understood that the total number of the second wheels 30 commonly mounted at the two ends of the mounting arm 16 is not limited to four, and for example, the total number of the second wheels 30 commonly mounted at the two ends of the mounting arm 16 may be two, three, four or more.
Other embodiments of handpiece assembly 100 will be described below in terms of the total number of second wheels 30 that are mounted together on either end of mounting arm 16.
Referring to fig. 8, in other embodiments, two ends of the mounting arm 16 are respectively provided with one of the second wheels 30. In total, both of the second wheels 30 are located on a straight line along the horizontal axis x. For example, in total, one of the two second wheels 30 is sleeved on the first connecting shaft 162 and located between the two side arms 160, and the other is sleeved on the second connecting shaft 164 and located between the two side arms 160.
Referring to fig. 9, in other embodiments, the total number of the second wheels 30 mounted at both ends of the mounting arm 16 is three, and the three second wheels 30 can form a triangular support structure on the horizontal plane p, so as to ensure the stability of the base assembly 10 and prevent the base assembly from falling down easily, and meanwhile, the number of the second wheels 30 is small, and the cost is lower. Of the three second wheels 30, one is mounted to the end of the mounting arm 16 that is closer to the base 12, and the remaining two are mounted to the end of the mounting arm 16 that is further from the base 12. For example, one of the three second wheels 30 is disposed around the first connecting shaft 162 and between the two side arms 160, and the remaining two second wheels are respectively mounted at two ends of the second connecting shaft 162.
It should be noted that, as long as the total number of the second wheels 30 mounted on both ends of the mounting arm 16 is at least three, at least one triangular support structure can be formed on the horizontal plane p to improve the stability of the base assembly 10.
It is to be understood that, depending on the actual situation, it is not limited to mounting the second wheels 30 at both ends of the mounting arm 16, and the handpiece base 100 can be implemented as follows.
Referring to fig. 7, in some other embodiments, an end of the mounting arm 16 near the base 12 is mounted on the fixed shaft 140. The second wheel 30 is mounted to the end of the mounting arm 16 remote from the base 12.
Referring to fig. 10, a power retractable door 200 according to another embodiment of the present invention includes a door row 60 and the handpiece assembly 100 as described above.
The door row 60 is mounted to the base assembly 10 of the head assembly 100, and the door row 60 is retractable in a horizontal direction x.
In some embodiments, the door row 60 is mounted to the base assembly 10 by a hinge assembly 62, and the door row assembly 60 can rotate relative to the base assembly 10 around the horizontal longitudinal direction y, so that when the ground is uneven in height, the base assembly 10 and the door row can be prevented from being lifted or sunk at the same time, and the overall smoothness of the electric retractable door can be improved.
One end of the hinge assembly 62 is mounted to the door row 60, one end of the hinge assembly 62 is rotatable with respect to the door row 60 about a horizontal longitudinal direction y, the other end of the hinge assembly 62 is mounted to the base assembly 10, and the other end of the hinge assembly 62 is rotatable with respect to the base assembly 10 about the horizontal longitudinal direction y.
Since the base assembly 10 is rotatably connected to the door row 60, there is a risk of being lifted, and by configuring the head assembly 100 as described in the previous embodiment, the head assembly 100 adopts a two-wheel driving manner, but when the end of the base assembly 10 where the first wheel 20 is installed is lifted, that is, when the first wheel 20 is spaced from the horizontal plane p by the preset distance d, the braking device 50 abuts against the second wheel 30 to prevent the second wheel 30 from rotating, and the head assembly 100 cannot be manually pushed.
In some embodiments, the end of the base assembly 10 where the second wheel 30 is installed is received in the door row 60, so that the second wheel 30 installed on the wheel frame 14 is hidden, and the distance between the second wheel 30 and the rear wheel is small, so that the size of the handpiece assembly is reduced, and the cost is reduced. In addition, the problem that the head assembly is difficult to steer when the electric retractable door is used for correcting the deviation can be avoided due to the small distance between the rear wheels.
The door row 60 is mounted to the base 12 of the base assembly 10, and the wheel frame 14 is received in the door row 60.
The door row 60 is provided with a receiving channel extending in a horizontal transverse direction x, which extends to the bottom of the door row 60 for receiving the wheel carriage 14.
In addition, since the dimension of the wheel carriage along the horizontal longitudinal direction y is smaller than the dimension of the base 12 along the horizontal longitudinal direction y, the wheel carriage 14 is facilitated to be accommodated in the door row 60.
