Description

Technical Field

[0001] The utility model relates to the technical field of daily life appliances, and particularly relates to a laser TV cabinet. Background Art

[0002] A laser TV uses a laser light source and a professional screen to form an image through a reflection principle. Compared with traditional TVs, laser TVs have the advantages of large size, high definition, vivid colors, and eye protection.

[0003] In order to avoid the problem that the body of the laser TV is accidentally touched, causing the body of the laser TV to move and affecting the projection effect or damaging the laser TV, and in order to save space, improve the aesthetic degree of indoor decoration, and at the same time avoid the accumulation of dust on the laser TV, generally, the laser TV cabinet used to arrange the laser TV is set to be hidden, that is, when the laser TV is not in use, the laser TV can be hidden in the laser TV cabinet.

[0004] A common hidden laser TV cabinet is of a drawer telescopic type. When using this laser TV cabinet, the laser TV is placed in the drawer of the laser TV cabinet. When the laser TV is not in use, the drawer with the laser TV is retracted into the cabinet body of the laser TV cabinet; when using the laser TV, the drawer with the laser TV is extended, and the laser TV can be projected. However, there are some problems when using this drawer telescopic laser TV cabinet. Mainly when using the laser TV, even when the drawer with the laser TV is extended, due to the shielding of the top plate of the laser TV cabinet (that is, the plate body of the laser TV cabinet above the drawer), the projection angle of the laser TV (the angle between the maximum projection direction and the vertical direction) is small, resulting in a small projection screen. As Figure 1 shown, the projection area is S1 = L * W1, where L is the projection length and W1 is the projection width.

[0005] In order to solve the problem that the projection screen of the laser projected by the laser TV is small due to the shielding of the top plate of the laser TV cabinet, people thought of making the top plate of the laser TV cabinet move upward and in the direction away from the extension of the drawer while the drawer of the laser TV cabinet extends. For example, the Chinese utility model patent with the publication number CN213640212U discloses a driving device for a new type of laser TV cabinet. However, this method is not applicable to the situation where the space where the laser TV cabinet is placed is relatively limited, such as the scene where the space behind (the side away from the extension of the drawer) or above the laser TV cabinet is limited. Utility Model Content

[0006] In order to solve at least one of the above problems, according to one aspect of the present utility model, a laser TV cabinet is provided.

[0007] The laser TV cabinet includes a cabinet body; a drawer for placing a laser TV and configured to be extendable relative to the cabinet body to a first position; a first top plate disposed above the bottom plate of the drawer, the first top plate being hinged to the cabinet body by a first hinge shaft and capable of rotating relative to the cabinet body to a first set position where the first end in front of it is lower than the first hinge shaft; the first top plate is further configured such that when the drawer is in the first position, the first top plate can be in the first set position.

[0008] Thus, when the laser TV is to be used, the drawer with the laser TV can be extended relative to the cabinet body to the first position, and the first top plate can be moved to the first set position; since the first end of the first top plate at the first set position is lower than the first hinge shaft, that is, the first end of the first top plate is inclined towards the side where the laser TV is located, the blockage of the transmission path of the laser TV is reduced, so that without increasing the extension distance of the drawer and without occupying the space above or behind the laser TV cabinet, the projection screen of the laser TV can be enlarged.

[0009] In some embodiments, the drawer is further configured to be retractable relative to the cabinet body to a second position; the first top plate is further configured such that its first end can rotate away from the side where the bottom plate of the drawer is located to a second set position; the first top plate is further configured such that when the drawer is in the second position, the first top plate can be in the second set position, and the part enclosed by at least one of the first top plate, the cabinet body and the drawer can block the upper part of the laser TV placed in the drawer. Thus, at least one of the first top plate, the cabinet body and the drawer can block dust for the laser TV when the drawer is retracted to the second position and the laser TV is not in use, playing a role in protecting the laser TV; and / or the first top plate is further configured such that when the drawer is in the second position, the top surfaces of at least two of the first top plate, the drawer and the cabinet body can be in the same plane. Thus, in the state where the laser TV is not in use and the drawer is retracted to the second position, the top surface of the laser TV cabinet can form a plane like a general cabinet body to maintain the aesthetic feeling of the laser TV cabinet when the laser TV is in a non-use state.

[0010] In some embodiments, the cabinet body is further provided with a first limiting portion for limiting the first set position of the first top plate. Thus, the angle of the swing of the first end of the first top plate towards the side where the bottom plate of the drawer is located can be limited by the first limiting portion; and / or the first hinge shaft is disposed at the end of the first top plate far from its first end. Thus, when the first top plate moves towards the first set position, the external occupied space of the laser TV cabinet will not be increased.

[0011] In some embodiments, the laser TV cabinet further includes a motion mechanism; the motion mechanism is configured to be able to drive the first top plate to move to a first set position; and / or the motion mechanism is configured to be able to drive the first top plate to move to a second set position. Thus, the first top plate can be driven to move by the motion mechanism.

[0012] In some embodiments, the motion mechanism includes a first driving device disposed on the cabinet body and configured to drive the first top plate to reciprocate between a first set position and a second set position. Thus, the first top plate can be driven to reciprocate between the first set position and the second set position by the first driving device.

[0013] In some embodiments, the motion mechanism is configured to be able to drive the first top plate to move towards the first set position during the process of the drawer moving towards the first position; and / or the motion mechanism is configured to be able to drive the first top plate to move towards the second set position during the process of the drawer moving towards the second position.

[0014] Thus, the linkage of the movement of the first top plate and the drawer can be realized through the motion mechanism. When using the laser TV, the occlusion of the transmission path of the laser TV by the first top plate can be reduced, and the projection area of the laser TV can be increased without increasing the occupied space of the laser TV cabinet; and when the laser TV is not in use, the first top plate can provide protection such as dust prevention and anti-collision for the laser TV.

[0015] As some embodiments in which the movement of the first top plate and the drawer can be linked, the motion mechanism includes a first swing member, and the first swing member is respectively hinged to the first top plate and the cabinet body through a second hinge shaft and a third hinge shaft; the first swing member is configured such that during the process of the drawer moving towards the second position, the drawer can abut against the first swing member to drive the first swing member to rotate around the third hinge shaft, and the first swing member drives the first top plate to move towards the second set position.

[0016] Thus, the linkage between the drawer moving towards the second position and the first top plate moving towards the second set position can be realized through the first swing member hinged to the first top plate and the cabinet body and the positional relationship between the first swing member and the drawer; during the process of the drawer moving to the first position, since the drawer is separated from the first swing member and the first swing member loses the power to drive the first top plate, the first end of the first top plate swings towards the side where the bottom plate of the drawer is located (generally downwards) under the action of its own gravity until the first top plate moves to the first set position.

[0017] In some embodiments, on the basis that the motion mechanism includes a first swing member, the motion mechanism further includes a first roller hinged to the first swing member through a fourth hinge shaft; the fourth hinge shaft is parallel to at least one of the second hinge shaft and the third hinge shaft; the first swing member abuts against the drawer through the first roller.

[0018] During the movement of the drawer towards the second position, while the drawer abuts against the first swing member, the first swing member will also swing relative to the drawer to drive the first top plate to move to the second set position; when the first swing member abuts against the drawer through the first roller hinged thereto, when the first swing member swings relative to the drawer, the friction force received by the drawer is the rolling friction of the first roller, thereby reducing the friction force received by the drawer.

[0019] As some embodiments in which the movements of the first top plate and the drawer can be linked, the movement mechanism includes a guiding section provided on the drawer, and the guiding section is arranged to provide guidance for the movement of the first top plate between the first set position and the second set position. Thus, during the movement of the drawer towards the second position, the guiding section can provide guidance for the movement of the first top plate towards the second set position, thereby realizing the linkage between the movement of the drawer towards the second position and the movement of the first top plate towards the second set position.

[0020] In some embodiments, on the basis that the movement mechanism includes a guiding section, the movement mechanism further includes a second roller hinged to the first top plate through a fifth hinge shaft, and the second roller is arranged such that when the first top plate moves between the first set position and the second set position, the first top plate abuts against the guiding section through the second roller. Since during the movement of the drawer towards the second position, under the action of the guiding section, the first top plate will also move relative to the guiding section; when the first top plate abuts against the guiding section through the second roller hinged thereto, the friction force received by the guiding section can be reduced.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Figures 2 to 7 A laser TV cabinet is schematically shown according to an embodiment of the present invention.

[0040] As Figure 4 shown, the laser TV cabinet includes a cabinet body 20, a drawer 30, a first top plate 50, and a first swing member 72. The drawer 30 is used to place a laser TV 40 (for example, the laser TV 40 is placed on the bottom plate 31 of the drawer 30), and can extend from the front side 21 of the cabinet body 20 to the first position, as Figures 2 to 4 shown; the drawer 30 can also retract relative to the cabinet body 20 to the second position, as Figures 5 to 7 shown. The first top plate 50 is hinged to the cabinet body 20 through a first hinge shaft 60 and is arranged above the bottom plate 31 of the drawer 30; at the same time, the first top plate 50 can rotate relative to the cabinet body 20 around the first hinge shaft 60 to the first set position, as Figures 2 to 4 shown; when the first top plate 50 is in the first set position, the first end 51 of the first top plate 50 in front of it is lower than the first hinge shaft 60; moreover, when the drawer 30 is in the first position, the first top plate 50 can be in the first set position. The first swing member 72 is hinged to the first top plate 50 and the cabinet body 20 through a second hinge shaft 721 and a third hinge shaft 722 respectively; while the first swing member 72 rotates around the third hinge shaft 722, it can drive the first end 51 of the first top plate 50 to rotate away from the side where the bottom plate 31 of the drawer 30 is located to the second set position, or drive the first end 51 of the first top plate 50 to rotate towards the side where the bottom plate 31 of the drawer 30 is located to the first set position.

[0041] Thus, when the laser TV 40 is to be used, the drawer 30 with the laser TV 40 can be extended relative to the cabinet body 20 to the first position; and the first end 51 of the first top plate 50 can be swung towards the side where the bottom plate 31 of the drawer 30 is located (generally downward) until the first top plate 50 moves to the first set position, such as Figures 2 to 4 shown. Since the first end 51 of the first top plate 50 at the first set position is lower than the first hinge axis 60, that is, the first end 51 of the first top plate 50 is inclined towards the side where the laser TV 40 is located, the blockage of the transmission path of the laser TV 40 is reduced, so that without increasing the extension distance of the drawer 30 and without occupying the rear of the laser TV cabinet, the projection screen of the laser TV 40 can be increased, such as Figure 8 shown. The projection area of the laser TV 40 placed in the laser TV cabinet of the present invention is S2 = L*(W1 + W2), where L is the projection length and W1 + W2 is the projection width. It can be seen that S2 > S1.

[0042] In some preferred embodiments, such as Figure 4 shown, the first swing member 72, the second pivot shaft, the third pivot shaft and the drawer 30 are arranged such that when the drawer 30 moves towards the second position, the drawer 30 can abut against the first swing member 72 to drive the first swing member 72 to rotate around the third hinge axis 722; at the same time, the first swing member 72 can drive the first end 51 of the first top plate 50 to rotate away from the side where the bottom plate 31 of the drawer 30 is located to the second set position, so as to realize the linkage of the movement of the first top plate 50 and the drawer 30 and improve the operation efficiency of the laser TV cabinet.

[0043] Thus, when the laser TV 40 is to be used, the drawer 30 with the laser TV 40 can be extended relative to the cabinet body 20 to the first position; during the process of the drawer 30 extending to the first position, the drawer 30 is gradually separated from the first swing member 72, so that the first swing member 72 loses the drive of the drawer 30 and thus cannot keep the first top plate 50 at the first set position. Also, due to the action of its own gravity, the first end 51 of the first top plate 50 swings towards the side where the bottom plate 31 of the drawer 30 is located (generally downward) until the first top plate 50 moves to the first set position, such as Figures 2 to 4 shown.

[0044] In some preferred embodiments, such as Figure 7 shown, when the drawer 30 is at the second position and the first top plate 50 is at the second set position, at least a part of the enclosure formed by the first top plate 50, the cabinet body 20 and the drawer 30 can block the upper part of the laser TV 40 placed in the drawer 30, so as to block dust for the laser TV 40 when the laser TV 40 is not in use and play a role in protecting the laser TV 40.

[0045] In some preferred embodiments, as Figures 5 to 7 shown, when the drawer 30 is in the second position and the first top plate 50 is in the second set position, the top surfaces of at least two of the first top plate 50, the drawer 30, and the cabinet body 20 can be located in the same plane, so that when the laser TV 40 is not in use, the top surface of the laser TV cabinet can form a plane like that of a general cabinet body 20, maintaining the aesthetic appearance of the laser TV cabinet.

[0046] In some preferred embodiments, as Figure 4 shown, the cabinet body 20 is further provided with a first limiting portion 22 for limiting the first set position of the first top plate 50, so as to limit the angle of the first end 51 of the first top plate 50 swinging towards the side where the bottom plate 31 of the drawer 30 is located through the first limiting portion 22. In some specific embodiments, the first limiting portion 22 is a stepped surface integrally formed or processed on the cabinet body 20.

[0047] In some embodiments, with continued reference to Figure 4 shown, the first swing member 72, the second hinge shaft 721, and the third hinge shaft 722 together constitute a motion mechanism 70 of an embodiment of the present utility model. The first swing member 72 can drive the first top plate 50 to reciprocate between the first set position and the second set position by rotating around the third hinge shaft 722. In some preferred embodiments, by setting the positional relationship between the motion mechanism 70 and the drawer 30, it can be made that during the process of the drawer 30 moving towards the second position, the motion mechanism 70 can drive the first top plate 50 to move towards the second set position, that is, realize the linkage of the drawer 30 moving towards the second position and the first top plate 50 moving towards the second set position. In some preferred embodiments, on the basis that the motion mechanism 70 includes the first swing member 72, the motion mechanism 70 further includes a first roller 724 hinged to the first swing member 72 through a fourth hinge shaft 723; the fourth hinge shaft 723 is parallel to at least one of the second hinge shaft 721 and the third hinge shaft 722; the first swing member 72 abuts against the drawer 30 through the first roller 724, so that when the first swing member 72 swings relative to the drawer 30, the friction force received by the drawer 30 is the rolling friction of the first roller 724, thereby reducing the friction force received by the drawer 30.

[0048] In some specific embodiments, as Figure 4 shown, the first pivot hinge shaft is perpendicular to the movement direction of the drawer 30.

[0049] In some specific embodiments, as Figure 4 shown, the first hinge shaft 60 is parallel to at least one of the second hinge shaft 721 and the third hinge shaft 722.

[0050] In some preferred embodiments, as Figure 4As shown, the first hinge shaft 60 is provided at one end of the first top plate 50 away from its first end 51.

[0051] In some embodiments, as Figure 4 shown, a second driving device 81 is installed on the cabinet body 20. The second driving device 81 is, for example, a rotating motor. The output shaft of the rotating motor is coaxially connected with a first lead screw 82. The first lead screw 82 is arranged along the moving direction of the drawer 30. A first nut 83 is adapted to the first lead screw 82, and the first nut 83 is fixedly arranged relative to the drawer 30. Thus, the second driving device 81 can drive the first lead screw 82 to rotate, so as to drive the first nut 83 to drive the drawer 30 to reciprocate between a first position and a second position.

[0052] In some preferred embodiments, as Figure 4 shown, in order to facilitate the hinging of the first swinging member 72 and the first top plate 50, a first connecting member 52 is provided on the first top plate 50. The first swinging member 72 is hinged to the first connecting member 52 through a second hinge shaft 721.

[0053] Figure 9 Schematically shows a laser TV cabinet according to an embodiment of the present invention. The main difference between the laser TV cabinet of this embodiment and the laser TV cabinet of the previous embodiment is that: as Figure 9 shown, in this embodiment, the moving mechanism 70 does not set the first swinging member 72, the second hinge shaft 721 and the third hinge shaft 722, but sets a first driving device 71 on the cabinet body 20 that can drive the first top plate 50 to move to a first set position and / or a second set position. In some specific embodiments, the first driving device 71 is a cylinder or a hydraulic cylinder. Its cylinder body is hinged to the cabinet body 20, and the free end of its piston rod is hinged to the first top plate 50. Preferably, the two hinge shafts are parallel to the first hinge shaft 60. In some preferred embodiments, as Figure 9 shown, in order to facilitate the hinging of the cylinder body and the first top plate 50, a second connecting member 53 is provided on the first top plate 50. The cylinder body is hinged to the second connecting member 53 through a hinge shaft.

[0054] In some preferred embodiments, when the laser TV cabinet is further provided with a second driving device 81, a control module, such as an MCU or a single-chip microcomputer, can also be introduced. During the process that the second driving device 81 drives the drawer 30 to move between a first position and a second position, the first driving device 71 is controlled to drive the first top plate 50 to move between a first set position and a second set position, so that when the drawer 30 is in the first position, the first top plate 50 can move to the first set position; and when the drawer 30 is in the second position, the first top plate 50 can move to the second set position, so as to realize the linkage of the movement of the first top plate 50 and the drawer 30.

[0055] Figures 10 to 12 Schematically shows a laser TV cabinet according to an embodiment of the present utility model. The main difference between the laser TV cabinet of this embodiment and that of the previous embodiment is that, as Figure 12 shown, in this embodiment, the movement mechanism 70 does not drive by setting the first driving device 71, but by setting a guiding section 73 on the drawer 30, and the guiding section 73 provides guidance (drive) for the movement of the first top plate 50 between the first set position and the second set position. In some specific embodiments, with continued reference to Figure 12 shown, the guiding section 73 can be set as an inclined plane whose second end 32 close to the first top plate 50 is inclined away from the first top plate 50. In other specific embodiments, the guiding section 73 can be set as an arc surface whose second end 32 close to the first top plate 50 is inclined away from the first top plate 50.

[0056] In some preferred embodiments, the guiding section 73 is set such that when the drawer 30 moves towards the first position, under the guiding action of the guiding section 73, the first top plate 50 can move to the first set position; when the drawer 30 moves towards the second position, under the guiding action of the guiding section 73, the first top plate 50 can move to the second set position, so as to realize the linkage of the movement of the first top plate 50 and the drawer 30.

[0057] In some preferred embodiments, as Figure 12 shown, on the basis that the movement mechanism 70 includes the guiding section 73, the movement mechanism 70 further includes a second roller 75 hinged to the first top plate 50 through a fifth hinge shaft 74, and the second roller 75 is set such that when the first top plate 50 moves between the first set position and the second set position, the first top plate 50 abuts against the guiding section 73 through the second roller 75, so as to reduce the friction force received by the guiding section 73 when the first top plate 50 abuts against the guiding section 73 through the second roller 75 hinged thereon and moves relative to the guiding section 73.

[0058] In some preferred embodiments, as Figure 12 shown, in order to facilitate the hinging of the second roller 75 and the first top plate 50, a third connecting member 54 is provided on the first top plate 50, and the second roller 75 is hinged to the third connecting member 54 through a fifth hinge shaft 74.

[0059] In the present utility model, the connection or installation is a fixed connection without special emphasis. The fixed connection can be realized as a detachable connection or a non-detachable connection commonly used in the prior art. The detachable connection can be realized by the prior art, such as threaded connection or key connection, etc. The non-detachable connection can also be realized by the prior art, such as welding or gluing, etc.

[0060] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
