Referring to fig. 1-3, the present embodiment provides a housing structure 100, and accordingly, a projector (not shown).

The projector includes a housing structure 100, and also includes a projection part (not shown) disposed in the housing structure 100. Specifically, the projection section includes a lens or the like.

The housing structure 100 includes a housing 120 and an upper cover 110 covering the housing 120. Meanwhile, the upper cover 110 further has a first limiting portion 113, a second limiting portion 130 matched with the first limiting portion 113 is arranged on the housing 120, the second limiting portion 130 is used for limiting the movement of the first limiting portion 113 along the separation direction of the buckle 112, so that under the condition that the upper cover 110 and the housing 120 are separated, the upper cover 110 and the housing 120 are kept connected through the matching of the first limiting portion 113 and the second limiting portion 130, the problem of line damage caused by the fact that the upper cover 110 and the housing 120 are easy to separate is solved, the reliability of the shell structure 100 is improved, and the maintenance cost is reduced.

The housing structure 100 provided in the present embodiment is further described below:

with reference to fig. 1-3, in the present embodiment, the outer casing 120 is a shell-shaped structure having an opening 121 at an upper end thereof. The upper cover 110 includes a cover 111, a buckle 112 and a first limiting portion 113, the cover 111 is a square plate-shaped member, the buckle 112 and the first limiting portion 113 are both fixedly connected to the lower end surface of the cover 111, the plurality of buckles 112 are uniformly distributed along the periphery of the cover 111, and the first limiting portion 113 is disposed near the middle of the cover 111 compared with the buckle 112. The cover 111 is used for covering the opening 121 of the housing 120, so as to close the opening 121 of the housing 120. A groove 122 is provided inside the opening 121 of the housing 120, and the cover 111 is fixed to the housing 120 by engaging the groove 122 with the latch 112. Specifically, during installation, the upper cover 110 covers from top to bottom, and the latch 112 is latched to the groove 122, that is, the latching direction of the latch 112 is a vertical downward direction, and correspondingly, the disengaging direction of the latch 112 is a vertical upward direction.

Fig. 4 is a schematic structural diagram of the second position-limiting portion 130 in the housing structure 100 according to the present embodiment. Referring to fig. 1 to 4, in the embodiment, the second position-limiting portion 130 includes a position-limiting block 131, the position-limiting block 131 is slidably connected to the housing 120, and the position-limiting block 131 is used for being clamped with the first position-limiting portion 113 to limit the movement of the first position-limiting portion 113 in the vertical upward direction.

Further, the second limiting portion 130 further includes an elastic member 134, one end of the elastic member 134 acts on the limiting block 131, and is used for applying an elastic force towards the first limiting portion 113 to the limiting block 131, so that the limiting block 131 is abutted against the first limiting portion 113, and a limiting effect on the first limiting portion 113 is ensured, and further, the external force required for disengaging the limiting block 131 and the first limiting portion 113 along the vertical upward direction is far greater than the external force required when the buckle 112 and the groove 122 are disengaged, so that under the condition that the buckle 112 and the groove 122 are disengaged, the limiting block 131 and the first limiting portion 113 keep matching.

Specifically, the stopper 131 is slidably disposed in the housing 120 in the horizontal direction, the elastic member 134 is horizontally disposed at one side of the stopper 131, and the other end is in contact with the housing 120, so that the elastic member 134 is pressed in the case where the stopper 131 slides in the direction away from the first stopper portion 113 with respect to the housing 120, and accordingly, the elastic force generated by the elastic member 134 in the direction approaching the first stopper portion 113 acts on the stopper 131. The housing 120 has a bracket 123 for mounting the projection component therein, and the stopper 131 is slidably connected to the bracket 123.

Optionally, two ends of the stopper 131 are provided with a strip-shaped hole 133 side by side, and the connecting screw passes through the strip-shaped hole 133 to be connected with the bracket 123, so that the stopper 131 can slide along the extending direction of the strip-shaped hole 133 relative to the housing 120. The elastic member 134 is a spring, and both ends thereof are connected to the stopper 131 and the bracket 123, respectively.

In this embodiment, the first position-limiting portion 113 includes a connecting arm 114 and a hook 115 fixedly connected to one end of the connecting arm 114, and the first position-limiting portion 113 is a hook-shaped structure, so that when the first position-limiting portion is clamped, the upper sidewall of the hook 115 abuts against the limiting block 131, thereby limiting the upward movement of the hook 115. The upper end of the connecting arm 114 is fixedly connected to the cover 111.

Specifically, the lower end surface of the limiting block 131 is used for abutting against the upper side surface of the hook 115, so as to limit the vertical upward movement of the hook 115, and meanwhile, when the upper side surface of the hook 115 abuts against the lower end surface of the limiting block 131, the limiting block 131 and the first limiting portion 113 are in a clamped state.

Further, the first limiting portion 113 has a first guiding inclined surface 116, the limiting block 131 has a second guiding inclined surface 132, the first guiding inclined surface 116 abuts against the second guiding inclined surface 132, so that when the first limiting portion 113 moves in the direction (i.e., the vertical downward direction) in which the limiting block 131 is inserted, the limiting block 131 is pushed to move in the direction away from the first limiting portion 113 relative to the housing 120, so that the first limiting portion 113 can pass over the limiting block 131 until the hook 115 of the first limiting portion 113 is located below the limiting block 131, and after the limiting block 131 is reset under the action of the elastic member 134, the limiting block 113 is limited by the abutting of the limiting block 131 and the hook 115.

Meanwhile, the distance from the limiting block 131 to the opening 121 of the housing 120 is smaller than the distance between the hook 115 and the cover 111, so that a gap exists between the cover 111 and the housing 120 under the condition that the hook 115 is clamped with the limiting block 131, and thus when the upper cover 110 needs to be detached, other auxiliary tools are adopted to extend into the housing 120 from the gap and drive the limiting block 131 to move in the direction away from the first limiting portion 113, so that the first limiting portion 113 is unlocked. Correspondingly, the lower side of the limiting block 131 has a space for the hook 115 to move downward, so that after the hook 115 abuts against the limiting block 131, the first limiting portion 113 can continue to move downward along with the cover 111 until the buckle 112 is clamped in the groove 122, and in this process, the limiting block 131 abuts against the connecting arm 114 under the action of the elastic member 134, so as to ensure that the relative position between the limiting block 131 and the first limiting portion 113 is stable.

It should be noted that the unlocking manner of the limiting block 131 and the first limiting portion 113 is not limited herein, and it can be understood that in other embodiments, other manners may also be adopted, for example, an unlocking piece is provided in the housing 120, and the unlocking movement of the limiting block 131 is realized by an electronic control or an operation of an unlocking key outside the housing 120.

According to the present embodiment, the shell structure 100 works according to the following principle:

during installation, the upper cover 110 is first moved downward relative to the housing 120 along a vertical downward direction until the first guiding inclined surface 116 of the first limiting portion 113 abuts against the second guiding inclined surface 132 of the limiting block 131, at this time, the upper cover 110 continues to move downward, and the limiting block 131 moves in a direction away from the first limiting portion 113 under the abutting action of the first guiding inclined surface 116 until the first guiding inclined surface 116 and the second guiding inclined surface 132 are dislocated and separated, and the elastic member 134 is compressed and elastically deformed in the process. Then, the upper cover 110 continues to move downwards until the upper side surface of the hook 115 moves to the lower side of the limiting block 131, the limiting block 131 is reset under the action of the elastic element 134, at this time, the hook 115 is clamped with the limiting block 131 (as shown in fig. 3), and the buckle 112 is not clamped in the groove 122. The upper cover 110 continues to move downwards until the latch 112 is latched with the groove 122, and at this time, the latch 115 is located at a distance below the stopper 131.

The present embodiment provides a housing structure 100 with at least the following advantages:

the shell structure 100 that this embodiment provided does not change the basis that original lid closed the mode, through the setting to first spacing portion 113 and the spacing portion 130 of second, has guaranteed under the circumstances that buckle 112 and recess 122 unhook, and upper cover 110 still keeps being connected with shell 120, and then has avoided appearing the problem that the PCB winding displacement harmd under the circumstances such as falling, the dismouting of being convenient for simultaneously.

Example 2

Fig. 5 is a schematic view of a matching structure of the first position-limiting portion 113 and the second position-limiting portion 130 in the housing structure 100 provided in this embodiment, and fig. 6 is a schematic view of a labyrinth groove 135 in the housing structure 100 provided in this embodiment. Referring to fig. 1 to 6, the present embodiment also provides a housing structure 100, which has a structure substantially the same as the housing structure 100 provided in embodiment 1, and the same parts are not repeated herein, except that the first position-limiting portion 113 and the second position-limiting portion 130 have different structures.

Specifically, in this embodiment, the first limiting portion 113 has a structure with a clamping protrusion 117 at a lower end, and the clamping protrusion 117 is disc-shaped. The second stopper portion 130 has a labyrinth groove 135 opened in the holder 123 of the housing 120, and the labyrinth groove 135 has a large-diameter section 136 and a small-diameter section 137 communicating with each other. The size of the opening 121 of the large-diameter section 136 is larger than that of the clamping protrusion 117, so that the clamping protrusion 117 can pass through the large-diameter section 136; the size of the opening 121 of the small-diameter section 137 is smaller than that of the clamping protrusion 117, so that after the first limiting portion 113 enters the small-diameter section from the large-diameter section 136, the clamping protrusion 117 is limited at the lower side of the small-diameter section 137, and therefore the first limiting portion 113 is limited.

Meanwhile, under the condition that the buckle 112 is clamped with the groove 122 of the housing 120, the first limiting portion 113 is matched with the small-diameter section 137, namely, the clamping protrusion 117 is limited at the lower side of the small-diameter section 137, the first limiting portion 113 cannot be separated from the labyrinth groove 135 along the vertical upward direction, and then the separation of the housing 120 and the upper cover 110 is avoided (as shown in fig. 5). If the upper cover 110 needs to be detached, the upper cover 110 is driven to move integrally only after the buckle 112 is unhooked, so that the first limiting portion 113 moves to the large-diameter section 136, and at this time, the clamping protrusion 117 can be pulled out of the labyrinth groove 135 from the large-diameter section 136 in a vertical upward direction.

Further, the direction from the large diameter section 136 to the small diameter section 137 forms an included angle with the extending direction of the small diameter section 137, that is, the labyrinth groove 135 is substantially in an L-shaped structure, so that to separate the first limiting portion 113 from the labyrinth groove 135, the upper cover 110 needs to slide along two directions relative to the housing 120, and then the first limiting portion 113 can move into the large diameter section 136.

Further, the number of the first limiting portions 113 and the second limiting portions 130 is two, and the two first limiting portions 113 and the two second limiting portions 130 are arranged in a one-to-one correspondence manner. Accordingly, the number of the labyrinth grooves 135 is two, and the two labyrinth grooves 135 are arranged side by side.

Example 3

Fig. 7 is a schematic structural diagram of the second position-limiting portion 130 in the housing structure 100 according to this embodiment. Referring to fig. 1 to 7, the present embodiment also provides a housing structure 100, which is substantially the same as the housing structure 100 provided in embodiment 2, and the same points are not repeated, but the difference is that the structure of the second position-limiting portion 130 is different.

Specifically, the second position-limiting portion 130 further includes a blocking piece 138. An inlet for the clamping protrusion 117 to enter the labyrinth groove 135 is formed at the large diameter section 136 of the labyrinth groove 135, and the blocking piece 138 is disposed on a path locus from the inlet to a section of the small diameter section 137 away from the large diameter section 136, so as to limit the first limiting portion 113 from a section of the small diameter section 137 away from the large diameter section 136 to the inlet. At this time, the large diameter section 136 is disposed at one end of the small diameter section 137 in the extending direction, so that the first position-limiting portion 113 can be reliably limited.

Optionally, the blocking piece 138 is an elastic piece, so that in the assembling and disassembling process, the first limiting portion 113 passes over the blocking piece 138 and moves to the other side of the blocking piece 138 through the elastic deformation of the blocking piece 138. It will be appreciated that in other embodiments, the flap 138 may be configured to be movably attached to the housing 120 to block the passageway or to open the passageway.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
