Description

Technical Field

[0001] The present invention relates to the technical field of projector packaging, and particularly to an intelligent leveling multi-purpose projector packing box. Background Art

[0002] As is well known, a projector is a widely used precision electronic device, and during its transportation and handling, a corresponding packing box is required for protection to prevent damage to the projector caused by accidental bumps, etc. When using a projector, a corresponding placement rack is generally needed to meet the external requirements for the best working conditions of the projector.

[0003] Currently, the packaging of projectors is generally a specific packing box or packaging bag designed according to their own sizes, and the placement rack can be a specially designed bracket or an item that can be temporarily borrowed in the usage scenario and has a relatively flat placement surface, such as a table, a chair, etc.

[0004] However, in order to improve the working conditions when using a projector, a corresponding packing box or packaging bag and a corresponding placement rack need to be carried each time. This is not only inconvenient to carry, but also the placement rack is easily bumped, resulting in an uneven placement surface (the surface where the projector is placed), and the placement surface is in direct contact with the projector, affecting the heat dissipation at the bottom of the projector, thus affecting the projector's ability to present the best working conditions. Moreover, the leveling operation of the placement rack is generally manually adjusted by humans, which is inaccurate and also results in a low erection efficiency of the projector. Therefore, an intelligent leveling multi-purpose projector packing box is proposed, which can not only serve as a packing box but also as a placement rack, and can perform automatic intelligent leveling, and can promote the efficient use of the projector by enhancing the stability of the projector placement and improving the heat dissipation of the projector. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent leveling multi-purpose projector packing box to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An intelligent leveling multi-purpose projector packing box, including a box body for placing a projector, a detection component and an electric control and power supply component are arranged inside the box body, leveling electric push rods are arranged at four corners inside the box body, the leveling electric push rods are connected with encoders, opening electric push rods are arranged on both sides inside the box body, and the movable ends of the opening electric push rods are connected with a top cover through a connecting plate;

[0007] The movable ends of the leveling electric push rods are arranged downward and pass through the inner bottom surface of the box body.

[0008] Preferably: The top cover is arranged in a rectangular frame shape, a flip cover is rotatably connected inside the top cover, and a plurality of grooves are vertically and horizontally opened on the bottom surface of the flip cover.

[0009] Preferably, rotation openings are formed in the middle sections of the two symmetric inner side walls of the top cover. A positioning opening is formed in the bottom surface of the top cover below the rotation openings. Rotating shafts are fixedly connected to the middle sections of the two symmetric side walls of the flip cover. The rotating shafts are placed in the rotation openings. A limiting notch is formed in the rotating shaft above the positioning opening. A positioning post is fixedly connected to the top surface of the box body at the positioning opening. When the top cover covers the box body, the positioning post passes through the positioning opening and enters the limiting notch, thereby restricting the rotation of the rotating shaft. At this time, the groove faces the inside of the box body.

[0010] Preferably, a concave sliding groove is formed in the top surface of the top cover. A plurality of L-shaped sliding blocks are slidably connected to the concave sliding groove. The upper ends of the L-shaped sliding blocks are slidably connected to a horizontal sliding shaft. A plurality of convex blocks are arranged around the central axis of the horizontal sliding shaft at one end of the horizontal sliding shaft facing the inner side of the top cover.

[0011] Preferably, there are two concave sliding grooves, and the concave sliding grooves are U-shaped. The two concave sliding grooves are symmetrically arranged on the top surface of the top cover.

[0012] Preferably, at least two L-shaped sliding blocks and the horizontal sliding shafts and convex blocks thereon are arranged on each side of the top surface of the top cover.

[0013] Preferably, an elastic sleeve rope is arranged on the convex block on the top surface of the top cover, and the elastic sleeve rope has elasticity.

[0014] Preferably, the horizontal sliding shaft can extend into the groove, thereby restricting the rotation of the flip cover.

[0015] Preferably, a cushion block is fixedly connected to the end of the leveling electric push rod outside the box body, and the material of the cushion block is rubber.

[0016] Preferably, the detection component can be set as a gyroscope or an acceleration sensor. The detection component is arranged at the center of the inner bottom surface of the box body. The electric control and power supply component includes a PLC and a battery. The PLC is used to receive the measured level signal of the detection component and control the opening and closing of the stepping motor in the leveling electric push rod. The battery is used to supply power to the detection component, the leveling electric push rod, the encoder and the cover-opening electric push rod. The PLC also includes a wireless communication module for receiving control commands.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Through the settings and coordinated cooperation of the detection component, the electric control and power supply component, the leveling electric push rod, etc., the detection information of the level of the box body by the detection component is fed back to the PLC in real time. The PLC then precisely controls the opening and closing of the stepping motor in the leveling electric push rod through the encoder, causing the movable end of the leveling electric push rod to extend or contract, thereby adjusting the level of the box body until the level detection information fed back by the detection component meets the usage requirements of the projector. This successfully realizes the fast and automated intelligent leveling of the box body, facilitating the use of the projector. At the same time, by setting the opening electric push rod, the opening and closing of the top cover are automated, and the height of the top cover can be adjusted as needed to adapt to the usage environment of the projector.

[0019] 2. The setting of the groove enables more efficient heat dissipation of the bottom surface of the projector when it is placed on it, thus facilitating the efficient use of the projector.

[0020] 3. Through the settings of the positioning posts, positioning holes, and limiting notches, etc., when the top cover is placed on the top surface of the box body, that is, when the box body is in the closed state, the flip cover is automatically locked due to the rotation of the rotating shaft being restricted, so that the groove on the flip cover always faces the inside of the box body when the box body is in the closed state. This avoids the surface with the groove on the flip cover from being deformed due to friction and extrusion during the movement and handling of the box body. When this device serves as a placement rack for the projector, the placement surface of the projector (the surface with the groove on the flip cover) is always flat, which is beneficial to the placement of the projector and improves the erection efficiency of the projector. The structural setting is delicate and the degree of automation is high.

[0021] 4. Through the settings and coordinated cooperation of the concave chute, L-shaped slider, elastic sleeve rope, etc., the horizontal sliding shaft is pulled by the elastic sleeve rope and extends into the groove to limit the rotation of the flip cover. While ensuring that the surface with the groove on the flip cover is horizontally upward, the elastic sleeve rope can surround the outside of the projector, enhancing the stability of the projector during use. The L-shaped slider can slide on the concave chute, enabling elastic sleeve ropes to surround projectors of different sizes and improving the applicability of this device.

If there is a description of first and second, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0037] Please refer to Figures 1 to 10 , the present invention provides a technical solution for an intelligent leveling multi-purpose projector packaging box:

[0038] An intelligent leveling multi-purpose projector packaging box includes a box body 1 for placing a projector 4. A detection component 101 and an electric control and power supply component 103 are arranged inside the box body 1. Leveling electric push rods 102 are arranged at the four corners inside the box body 1. The leveling electric push rods 102 are connected with encoders 105. Open cover electric push rods 5 are arranged on both sides inside the box body 1. The movable end of the open cover electric push rod 5 is connected with a top cover 2 through a connecting plate 501. The movable end of the leveling electric push rod 102 is arranged downward and passes through the inner bottom surface of the box body 1.

[0039] Among them, it should be supplemented and explained that the detection component 101 can be set as a gyroscope or an acceleration sensor. The detection component 101 is arranged at the center of the inner bottom surface of the box body 1. The electric control and power supply component 103 includes a PLC and a battery. It should be noted that the PLC can also be replaced by a single-chip microcomputer or other similar electric control components. The PLC is used to receive the measured level signal of the detection component 101 and control the opening and closing of the stepping motor in the leveling electric push rod 102. The battery is used to supply power to the detection component 101, the leveling electric push rod 102, the encoder 105 and the open cover electric push rod 5. The PLC also includes a wireless communication module for receiving control commands.

[0040] Through the settings and common cooperation of the detection component 101, the electric control and power supply component 103, the leveling electric push rod 102, etc., the detection information of the level of the box body 1 by the detection component 101 is fed back to the PLC in real time. The PLC then precisely controls the opening and closing of the stepping motor in the leveling electric push rod 102 through the encoder 105, so that the movable end of the leveling electric push rod 102 extends or shortens, thereby adjusting the level of the box body 1 until the level detection information fed back by the detection component 101 meets the usage requirements of the projector 4. The quick and automatic intelligent leveling of the box body 1 is successfully realized, which is convenient for the use of the projector 4. At the same time, by using the setting of the open cover electric push rod 5, the opening and closing of the top cover 2 is automated, and the height of the top cover 2 can be adjusted as needed to adapt to the usage environment of the projector 4.

[0041] Refer to Figure 4 and Figure 5As shown, in an optional embodiment: The top cover 2 is set as a rectangular frame shape. A flip cover 3 is rotatably connected inside the top cover 2. A plurality of grooves 302 are vertically and horizontally formed on the bottom surface of the flip cover 3. It should be noted that the horizontal grooves 302 and the vertical grooves 302 are perpendicular to and intersect with each other, and the grooves 302 penetrate through the side wall of the flip cover 3. The setting of the grooves 302 reduces the contact area between the projector 4 and the flip cover 3 when the projector 4 is placed thereon. The outside air can enter the bottom of the projector 4 through the grooves 302 to take out the heat, making the heat dissipation of the bottom surface of the projector 4 more efficient, thus facilitating the efficient use of the projector 4.

[0042] Referring to Figure 4 As shown, rotation openings 205 are formed in the middle sections of the symmetric two side walls inside the top cover 2. Referring to Figure 7 and Figure 8 As shown, positioning openings 206 are formed on the bottom surface of the top cover 2 at positions below the rotation openings 205. Rotating shafts 301 are fixedly connected to the middle sections of the symmetric two side walls of the flip cover 3. Referring to Figure 9 and Figure 10 As shown, the rotating shafts 301 are placed in the rotation openings 205. A limiting notch is formed at a position above the positioning opening 206 on the rotating shafts 301. A positioning post 104 is fixedly connected to the top surface of the box body 1 at the positioning opening 206. When the top cover 2 covers the box body 1, the positioning post 104 passes through the positioning opening 206 and enters the limiting notch, thereby restricting the rotation of the rotating shaft 301. At this time, the grooves 302 face the inside of the box body 1.

[0043] Through the settings of the positioning post 104, the positioning opening 206, the limiting notch, etc., when the top cover 2 is placed on the top surface of the box body 1, that is, when the box body 1 is in a closed state, the flip cover 3 is automatically locked because the rotation of the rotating shaft 301 is restricted, so that the grooves 302 on the flip cover 3 always face the inside of the box body 1 when the box body 1 is in a closed state, avoiding the surface of the flip cover 3 with the grooves 302 from being deformed due to friction and extrusion during the movement and handling of the box body 1. When this device serves as a placement rack for the projector 4, the placement surface of the projector 4 (the surface of the flip cover 3 with the grooves 302) is always flat, which is beneficial to the placement of the projector 4 and improves the erection efficiency of the projector 4. The structural setting is delicate and the degree of automation is high.

[0044] Referring to Figure 2 and Figure 3 As shown, concave sliding grooves 201 are formed on the top surface of the top cover 2. A plurality of L-shaped sliders 202 are slidably connected to the concave sliding grooves 201. The upper ends of the L-shaped sliders 202 are slidably connected to a horizontal sliding shaft 203. A plurality of convex blocks 204 are arranged around the central axis of the horizontal sliding shaft 203 at one end of the horizontal sliding shaft 203 facing the inside of the top cover 2. It should be noted that the convex blocks 204 are provided for hanging the elastic sleeve rope 6.

[0045] Among them, with reference to Figure 1 As shown, in an alternative embodiment: there are two concave sliding grooves 201, the concave sliding grooves 201 are U-shaped, and the two concave sliding grooves 201 are symmetrically arranged on the top surface of the top cover 2. Further, the L-shaped slider 202 and the concave sliding groove 201 are arranged in a matching manner, that is, the vertical section of the concave sliding groove 201 is L-shaped. With reference to Figure 3 As shown, the L-shaped slider 202 is slidably connected in the concave sliding groove 201 in a fitting manner.

[0046] It should be added that at least two L-shaped sliders 202, the horizontal sliding shafts 203 and the convex blocks 204 thereon are provided on each side of the top surface of the top cover 2. An elastic sleeve rope 6 is provided on the convex block 204 located on the top surface of the top cover 2. The elastic sleeve rope 6 has elasticity, and the horizontal sliding shaft 203 can extend into the groove 302, thereby restricting the rotation of the flip cover 3.

[0047] Through the settings and cooperation of the concave sliding groove 201, the L-shaped slider 202, the elastic sleeve rope 6, etc., the horizontal sliding shaft 203 is pulled by the elastic sleeve rope 6 and extends into the groove 302 to restrict the rotation of the flip cover 3. While ensuring that the surface of the flip cover 3 provided with the groove 302 is horizontally upward, the elastic sleeve rope 6 can surround the outside of the projector 4, enhancing the stability of the projector 4 during use. And the L-shaped slider 202 can slide on the concave sliding groove 201, so that projectors 4 of different sizes can be surrounded by the elastic sleeve rope 6, improving the applicability of the device.

[0048] With reference to Figure 1 As shown, in an alternative embodiment: a cushion block is fixedly connected to the end of the leveling electric push rod 102 located outside the box body 1. The material of the cushion block is rubber, which is used to protect the movable end of the leveling electric push rod 102 and prevent it from being worn.

[0049] Now, the working principle of the device is described through its use process: when using this device, when this device is used for packaging and carrying the projector 4, only the projector 4 needs to be placed inside the box body 1. At this time, the open cover electric push rod 5 is started, and the user rotates the flip cover 3 so that the groove 302 faces downward. Since the movable end of the open cover electric push rod 5 moves downward, and the connecting plate 501 is connected to the top cover 2, the top cover 2 gradually covers the top surface of the box body 1. At this time, the positioning column 104 passes through the positioning hole 206 and enters the limit notch, thereby locking the flip cover 3. Then the user can conveniently lift the box body 1 through the elastic sleeve rope 6 by sleeving the elastic sleeve rope 6 on the convex block 204.

[0050] When this device is used to set up the projector 4, start the open-cover electric push rod 5, so that the movable end of the open-cover electric push rod 5 moves upward, thereby pushing up the top cover 2. The user rotates the flip cover 3 to make the groove 302 face upward, takes out the projector 4 from the inside of the box body 1 and places it on the surface of the flip cover 3 where the groove 302 is provided. According to the size of the projector 4, slide the L-shaped slider 202 and sleeved the elastic sleeve rope 6 on the convex block 204. Under the elastic pulling of the elastic sleeve rope 6, the horizontal sliding shaft 203 extends into the groove 302, thereby restricting the rotation of the flip cover 3. After the projector 4 is placed, automatic intelligent leveling can be carried out.

[0051] The intelligent leveling is as follows: The detection component 101 will detect the levelness of the box body 1 and feedback the levelness detection information to the electric control and power supply component 103 in real time. The electric control and power supply component 103 will precisely control the opening and closing of the stepping motor in the leveling electric push rod 102 through the encoder 105, so that the movable end of the leveling electric push rod 102 extends or shortens, realizing the leveling operation of the box body 1 until the levelness detection information fed back by the detection component 101 to the electric control and power supply component 103 meets the usage requirements of the projector 4.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
