FIG. 8(b) is a side view of the position relationship between the projector, the fixing bracket, the sliding block, and the trolley wheel when the trolley wheel is in the first position. By defining the trolley wheel to be in the first position, it is meant that the driving lever on the trolley wheel forms an acute angle with the central axis of the projector. FIG. 8(c) is a front view of a position relationship between the projector, the fixing bracket, the sliding block, and the trolley wheel when the trolley wheel is in a second position. FIG. 8(d) is a side view of the position relationship between the projector, the fixing bracket, the sliding block, and the trolley wheel when the trolley wheel is in the second position. By defining the trolley wheel to be in the second position, it is meant that the driving lever on the trolley wheel is parallel to the central axis of the projector. FIG. 8(e) is a front view of a position relationship between the projector, the fixing bracket, the sliding block, and the trolley wheel when the trolley wheel is in a third position.

In this way, the problem that it is inconvenient to adjust a projector in the related art can be at least addressed, and user experience is improved.

Embodiment 5

FIG. 9 is a structural schematic diagram of components of an electronic device according to an embodiment. As shown in FIG. 9, the electronic device comprises: a support arm 10, a base portion 30 connected to one end of the support arm 10, and a head portion 20 connected to the other end of the support arm 10; wherein, the support arm 10 and head portion 20 are both provided therein with accommodation space for parts.

The head portion 20 comprises a projector assembly 31 which can at least project to a first area of a plane on which the base portion 30 is positioned; and the base portion 20 comprises a counterweight 91 which can control a height of a center of gravity of the electronic device below a preset height.

Specifically, the projector assembly 31 is mounted in the accommodation space of the head portion 20 and the counterweight 91 is mounted in the accommodation space of the base portion 30.

Of course, both the size and location of the accommodation space can be designed according to the requirement for the parts to be installed.

For example, the accommodation space in the head portion 20 may be named as the first accommodation space and the accommodation space in the base portion 30 as the second accommodation space. Various parts are connected in linear array in the first accommodation space of the head portion 20; and various parts are connected in linear array in the second accommodation space of the base portion 30. In this way, it is easier for various parts to be mounted in the accommodation space, whereby assembly time can be shortened, and it is also convenient for testing, repairing, and maintenance of the various parts.

Of course, the size and weight of the counterweight 91 may be configured according to actual needs. In this way, the counterweight 91 can make the base portion steadier so as to make the center of gravity of the entire device steadier. Herein, the lower the overall center of the device is, the more likely the electronic device is to remain still instead of being pushed down when under external stress (such as a pulling or pushing force).

As the projector assembly 31 is mounted on the head portion 20, the projector assembly 31 may be kept higher and the projector assembly 31 of a certain height from ground can enjoy a wider range of options in terms of projected areas and ranges. Of course, it is more convenient for the projector assembly 31 to project to the area of the plane on which the base portion 30 is positioned

In an embodiment, the housing for the support arm 10, the base portion 20, and the head portion 30 are of an integrated structure.

The housing may be made of an alloy. For example, the alloy can be an aluminum alloy, aluminum magnesium alloy, or the like.

In an embodiment the counterweight 31 may be of stainless steel. In this way, when the electronic device is placed on platforms with high humidity (such as an office floor, classroom podium, or on the ground in an open space), dampening, corrosion, and rust can better prevented, and further physical or chemical changes of the base portion that might influence the overall appearance of the device can be avoided.

Due to the integrated structure of the housing for the support arm 10, base portion 30, and head portion 20 of the electronic device in the embodiment, the device is easy to move. Moreover, when assembling the device, it is also convenient to mount various parts in the accommodation space which can shorten assembly time. Moreover, the shape of the housing can be more flexibly designed with a wider range of options. For example, the housing may be designed in a moon gate structure, semicircle arc, or scythe shape, etc. FIG. 10 is an ensemble schematic diagram of components of an electronic device according to an embodiment, wherein the shape of the device is a moon gate structure.

The head portion 20 comprises a projector assembly 31 which can at least project to the first area of the plane on which the base portion 30 is positioned. The base portion 30 comprises a counterweight 91 so that the height of the center of gravity of the electronic device can be below a preset height. The support arm 10 comprises: a controllable light bar 11 which, where the electronic device is under a first mode of utilization, illuminates a first side of the support arm 10 when illuminated.

Herein, the first operation mode may refer to: a case where the projector assembly 31 is in a working mode or a case where the projector assembly 31 is in an inactive mode.

The inner housing for the support arm 10 and/or the head portion 20 is a transparent member so that light can pass through the transparent member when the light bar in the support arm is illuminated. For example, the transparent member is made of acrylic or polycarbonate, etc. In this way, when the projector assembly 31 projects towards the first area of the plane on which the base portion 30 is positioned, the electronic device only functions as a projector when the controllable light bar 11 is off, and the device may function not only as a projector, but also as a table lamp which enhances the projection effect and helps the operator to control the projector assembly 31 when the controllable light bar 11 is on.

In this way, when the projector assembly 31 is in the inactive mode, the controllable light bar 11 may also be turned on so that the electronic device can function as a table lamp with illumination effect. For example, if the electronic device is placed on a classroom podium, and if the teacher's pen falls down to a corner of the podium, the teacher only needs to turn on the controllable light bar on the support arm 10 of the device to look for it.

FIG. 12 is a schematic diagram of light bar 11 on the support arm 10 according to an embodiment of the present invention. As in FIG. 12, the light bar 11 is located on the entire support arm 10. In this way, when the light bar 11 is turned on, the entire support arm 10 can emit light of the light bar to the outside.

For the electronic device stated in the embodiment, as the support arm 10 is provided therein with a controllable light bar 11, the device can both function as a table lamp and a projector, which makes it more convenient for the operator to control the projector assembly and can improve user experience.
