As described above, the projector 100 includes the housing, the bracket 20 and the connecting assembly 30, wherein the first side of the bracket 20 is hinged to the bottom cover 10 of the housing, so that the second side of the bracket 20 can rotate around the first side of the bracket 20 relative to the bottom cover 10, and specifically, the second side of the bracket 20 can rotate towards a direction close to or away from the bottom cover 10, so as to adjust a specific angle of an included angle between the bracket 20 and the bottom cover 10, thereby enabling the projector 100 to adjust a projection picture angle, and further meeting the actual requirement of a user on the projection picture angle. Further, the bracket 20 is further connected to the bottom cover 10 through the connecting assembly 30 to adjust an included angle between the bracket 20 and the bottom cover 10, in other words, the connecting assembly 30 can limit rotation between the bracket 20 and the bottom cover 10, that is, when the bracket 20 rotates relative to the bottom cover 10 until the included angle between the bracket 20 and the bottom cover 10 reaches a preset angle, the bracket 20 can be kept fixed relative to the bottom cover 10 without rotating relative to the bottom cover 10 through the connecting assembly 30, so that the projector 100 can keep a stable display image after the angle is adjusted.

As shown in fig. 1 to 4, in the present embodiment, the connecting assembly 30 includes a rotating block 31 and a limiting assembly 32, the rotating block 31 is fixedly connected to the first side of the bracket 20, and the rotating block 31 and the limiting assembly 32 are abutted against each other. The rotating block 31 is fixedly connected with the first side of the bracket 20, on one hand, the first side of the bracket 20 can be hinged with the bottom cover 10 and can be hinged with the bottom cover 10 through the rotating block 31, and on the other hand, the bracket 20 can be rotated and fixed with the bottom cover 10 and can be abutted with the limiting component 32 through the rotating block 31. For example, the rotating block 31 and the bracket 20 may be integrally formed during manufacturing, so as to improve the integrity and stability of the rotating block 31 and the bracket 20.

Specifically, as shown in fig. 1 to 4, in the present embodiment, the limiting component 32 includes a limiting block 321 and an elastic member 322, and the rotating block 31, the limiting block 321 and the elastic member 322 sequentially abut against each other; the rotating block 31 is provided with a plurality of limiting grooves 311 at intervals, and the limiting block 321 can be selectively received in any limiting groove 311.

As will be appreciated by those skilled in the art, the larger the number of the limiting grooves 311, the smaller the central angle of the single limiting groove 311 is divided, so that the difference between the included angles of the bracket 20 and the bottom cover 10 is smaller when the limiting blocks 321 are received in two adjacent limiting grooves 311. In addition, the shape and size of the limiting groove 311 should be adapted to the shape and size of the limiting block 321. In addition, the more gentle the protrusion and the narrower the width are, the more smooth the rotation of the limiting block 321 when switching between the two adjacent limiting grooves 311 is. The number of the limiting grooves 311, the shape and size of the limiting grooves 311, and the specific parameters of the protrusion are reasonably selected and designed by those skilled in the art according to practical situations, and are not limited herein.

It should be further noted that the limiting assembly 32 includes a limiting block 321 and an elastic member 322, the rotating block 31, the limiting block 321 and the elastic member 322 sequentially abut against each other, for example, when the limiting block 321 is accommodated in any limiting groove 311, the rotating block 31 (i.e. the limiting groove 311), the limiting block 321 and the elastic member 322 sequentially abut against each other, and since the left and right sides of the limiting block 321 are abutted by two sidewalls of the limiting groove 311, the support 20 and the bottom cover 10 can no longer rotate and remain fixed, so that the included angle between the support 20 and the bottom cover 10 can remain stable after reaching a certain angle; when the limiting block 321 is switched between two adjacent limiting grooves 311, the rotating block 31 (i.e. the protrusion), the limiting block 321 and the elastic member 322 sequentially abut against each other, and the left side and the right side of the limiting block 321 do not have an acting surface which abuts against each other, so that the bracket 20 and the bottom cover 10 cannot be fixed and can rotate, and the included angle between the bracket 20 and the bottom cover 10 can be adjusted.

It should be noted that when the limiting block 321 is accommodated in any one of the limiting grooves 311, the rotating block 31 (i.e., the limiting groove 311), the limiting block 321 and the elastic member 322 sequentially abut against each other, and when the limiting block 321 switches between two adjacent limiting grooves 311, the rotating block 31 (i.e., the protrusion), the limiting block 321 and the elastic member 322 sequentially abut against each other, and since the protrusion is closer to the bottom cover 10 than the limiting groove 311, the state and the length of the elastic member 322 are both changed adaptively in the above two position relationships. For example, as shown in fig. 1 to 4, in the present embodiment, the elastic member 322 may be a spring, or the elastic member 322 may also be another elastic product having elasticity and a certain stiffness.

As shown in fig. 1 to 4, in the present embodiment, the bottom cover 10 is provided with an accommodating groove 13, the bracket 20 is accommodated in the accommodating groove 13, and the accommodating groove 11 is opened on a bottom wall of the accommodating groove 13 to provide an accommodating space for the bracket 20 through the accommodating groove 13, so that the appearance of the projector 100 is more neat and beautiful. Preferably, the depth of the receiving groove 13 is equal to or slightly greater than the thickness of the bracket 20.

As shown in fig. 1, in the present embodiment, a first groove 14 is disposed on the bottom cover 10, a second groove 22 is disposed on a side wall of the second side of the bracket 20, the first groove 14 is disposed adjacent to the receiving groove 13, and the second groove 22 is disposed opposite to the first groove 14. In this way, when the bracket 20 is accommodated in the accommodating groove 13, the user can open the bracket 20 from the accommodating groove 13 through the second groove 22, and in the process, the first groove 14 can play a role of avoiding, so that the user can operate more conveniently. It is noted that the shapes of the first groove 14 and the second groove 22 in the drawings are merely illustrative and are not intended to limit the actual shapes of the first groove 14 and the second groove 22.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
