Description

Technical Field

[0001] The present invention relates to the technical field of logistics equipment, and in particular to a multi-dimensional synchronous telescopic mechanism and a box having the mechanism. Background Art

[0002] Logistics boxes, also known as turnover boxes and circulation boxes, are currently widely used in machinery, automobiles, home appliances, light industry, electronics and other industries because of their corrosion resistance, easy cleaning, easy stacking, easy management, mechanized operation and reusability. They are suitable for transportation, distribution, storage, circulation processing production, transportation, storage, sales and other links in factory logistics.

[0003] On the one hand, some existing logistics boxes, turnover boxes or storage cages do not have corresponding covers. When the items or goods placed there are afraid of moisture or squeezing, they need covers. Since the sizes of turnover boxes or storage cages vary greatly, covers of various sizes are required, which not only wastes resources, but also makes storage inconvenient and takes up a lot of storage space.

[0004] On the other hand, the existing logistics boxes cannot be customized according to different types and sizes of packaging materials because the box volume is fixed and cannot be changed. For packaged goods of different sizes, logistics boxes of different sizes need to be adapted for packaging, resulting in a large demand for logistics boxes but insufficient actual utilization. Such logistics boxes will generate varying degrees of space waste whether they are loaded or empty, thereby increasing storage and transportation costs. Although some logistics boxes in the existing technology also have telescopic functions, not only are the telescopic methods and dimensions single, but it is also difficult to make synchronous telescopic movements in three directions. In addition, manual telescopic movement is generally required, which is complicated to operate and increases labor costs.

[0005] Therefore, it is necessary to develop a mechanism that can achieve multi-dimensional automatic expansion and contraction. Summary of the Invention

[0006] In response to the existing technical problems, the present invention provides a multi-dimensional synchronous telescopic mechanism and a box having the mechanism.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: A multi-dimensional synchronous telescopic mechanism includes a rectangular panel and a cross sliding groove located at the center of the panel. The cross sliding groove divides the panel into multiple panel units, and adjacent panel units are arranged in a cross-overlapping manner. A driving rod is slidably installed in the cross sliding groove, and a driving source is provided at the center of the cross sliding groove. The driving source can rotate clockwise or counterclockwise, and the driving rod meshes with the driving source. A panel frame is provided around the panel. The panel frame includes corner connectors, middle supports, and telescopic rods located between the two. The middle support is connected to the driving rod, and the driving rod drives the middle support and its corresponding panel unit to move.

[0008] The beneficial effects of the present invention are as follows: In this application, by rotating the driving source clockwise or counterclockwise, the scaling of the panel unit is realized. According to the size of the object, one-dimensional scaling and two-dimensional scaling are controlled to save space, facilitate carrying, loading and unloading, and can be reused, which is environmentally friendly and practical. Connecting the driving rod to the middle support can not only ensure the stability of the telescopic rods on both sides but also not affect the telescopic movement of the telescopic rods.

[0009] On the basis of the above technical solution, in order to achieve the convenience of use and the stability of the equipment, the present invention can also make the following improvements to the above technical solution:

[0010] Further, the driving source is a gear, and a rack is provided on the driving rod. The rack meshes with the gear.

[0011] The beneficial effect of adopting the above further technical solution is that the rack meshes with the gear, and the gear can be controlled to stop at any position according to requirements, so that the telescopic mechanism presents an area of any size, better meeting the use requirements, with stable transmission, simple structure, low cost, and convenient use and maintenance.

[0012] Further, the driving rod is U-shaped. The driving rod includes a tooth rod and a support rod arranged in parallel. The rack is arranged on the inner side of the tooth rod, and pulleys are provided at the ends of the tooth rod and the support rod.

[0013] The beneficial effect of adopting the above further technical solution is that the U-shaped structure is simple, and the pulleys reduce the friction when the driving rod moves, ensuring the smoothness of the driving rod when it moves.

[0014] Further, the driving rod includes a horizontal driving rod and a vertical driving rod, and the horizontal driving rod and the vertical driving rod are arranged in a cross manner.

[0015] The beneficial effect of adopting the above further technical solution is that by setting the horizontal driving rod and the vertical driving rod, the horizontal and vertical scaling of the panel is realized, so as to better meet the user's needs.

[0016] Further, at least one lateral driving rod and at least one longitudinal driving rod are provided, and the driving rods in the same direction are staggered.

[0017] The beneficial effects of adopting the above further technical solution are as follows: at least one lateral driving rod and at least one longitudinal driving rod are provided, which can realize the horizontal and vertical scaling of the telescopic mechanism, better meet the usage requirements of customers, improve the applicable range of the telescopic mechanism, and the staggered arrangement can save the overall volume of the telescopic mechanism and is convenient for handling.

[0018] Further, a first pulley is provided at the end of the lateral driving rod, and a second pulley is provided at the end of the longitudinal driving rod.

[0019] The beneficial effects of adopting the above further technical solution are as follows: by providing pulleys, the smoothness of the driving rod during movement is ensured, friction is reduced, and power output is lowered.

[0020] Further, a sliding groove is provided in the cross-shaped sliding groove, the lateral driving rod and the longitudinal driving rod are respectively inserted into the sliding groove, third pulleys and fourth pulleys are provided on the sliding groove, the third pulley is in sliding fit with the longitudinal driving rod, and the fourth pulley is in sliding fit with the lateral driving rod.

[0021] The beneficial effects of adopting the above further technical solution are as follows: through the sliding fit of the pulleys and the driving rods, the guiding effect on the driving rods can be realized, and at the same time, the friction force during the movement of the driving rods can be reduced, making the driving rods move more smoothly.

[0022] Further, at least one driving source is provided.

[0023] The beneficial effects of adopting the above further technical solution are as follows: according to the usage situation, multiple driving rods can be simultaneously controlled by a single power source to realize the simultaneous scaling of the panel unit, realize two-dimensional scaling, or the panel unit can be controlled separately by different driving sources to realize one-dimensional scaling or multi-dimensional scaling, better meeting the usage requirements of customers.

[0024] Further, the driving source is connected to the output shaft of the driving motor.

[0025] The beneficial effects of adopting the above further technical solution are as follows: the connection between the power source and the driving motor has a simple structure and is convenient to operate.

[0026] A box body includes a multi-dimensional synchronous telescopic mechanism.

[0027] The beneficial effects of the present invention are as follows: by combining the telescopic mechanisms to form a box body, the box body can be scaled according to the size of the object loaded therein, so as to obtain the best packaging state and the smallest usage space, save the storage space of the object, and at the same time, the situation that the object collides due to too large a gap between the object and the box body can be avoided.

[0038] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0039] A multi-dimensional synchronous telescopic mechanism, as Figures 1 to 6As shown in the figure, it includes a rectangular panel and a cross-shaped sliding groove 10 located at the center of the panel. The cross-shaped sliding groove 10 divides the panel into multiple panel units 2, and adjacent panel units 2 are arranged in a cross-overlapping manner. A driving rod 3 is slidably installed in the cross-shaped sliding groove 10. A driving source 6 is provided at the center of the cross-shaped sliding groove 10. The driving source 6 can rotate clockwise or counterclockwise. The driving rod 3 meshes with the driving source 6. A panel frame is provided around the panel. The panel frame includes corner connectors 1, middle support members 8, and telescopic rods 9 located between the two. The middle support member 8 is connected to the driving rod 3, and the driving rod 3 drives the middle support member 8 and its corresponding panel unit 2 to move.

[0040] In this embodiment, a cross-shaped sliding groove 11 is provided in the cross-shaped sliding groove 10, and the driving rod 3 is slidably installed in the sliding groove 11. The driving rod 3 is welded to the middle support member 8. The panel is divided into four panel units, and adjacent panel units are stacked. The driving rod 3 drives the middle support rod 8 and the panel units 2 on both sides of the middle support rod 8 to expand and contract.

[0041] There are two cross-shaped sliding grooves 10. When in use, the two cross-shaped sliding grooves 10 are buckled together.

[0042] In this embodiment, both ends of the telescopic rod 9 are respectively fixed in the grooves in the corner connector 1 and the middle support member 8, and the telescopic rod 9 is telescoped by stretching or contracting the corner connector 1 and the middle support member 8.

[0043] The driving source 6 is a gear, and a rack is provided on the driving rod 3. The rack meshes with the gear. The driving rod 3 is meshed in the sliding groove 11 through the gear, and the driving rod 3 is telescoped by driving the gear to rotate by a driving motor 13. The number of rotation turns of the driving motor 13 is preset in advance so that the maximum rotation angle of the driving motor 13 does not exceed the stroke of the driving rod 3.

[0044] The driving rod 3 is U-shaped. The driving rod 3 includes a tooth rod 3-1 and a support rod 3-2 arranged in parallel. The rack is provided on the inner side of the tooth rod 3-1. Pulleys are provided at the ends of the tooth rod 3-1 and the support rod 3-2, and the other ends of the tooth rod 3-1 and the support rod 3-2 are connected together.

[0045] The driving rod 3 includes a horizontal driving rod and a vertical driving rod, and the horizontal driving rod and the vertical driving rod are cross-arranged. By setting the horizontal and vertical driving rods, horizontal and vertical contraction or expansion is realized.

[0046] In this embodiment, the horizontal driving rod and the vertical driving rod are cross-arranged up and down, and corresponding sliding grooves 11 are provided in the cross-shaped sliding groove 10.

[0047] At least one transverse drive rod and one longitudinal drive rod are provided, and the drive rods 3 in the same direction are arranged staggeredly.

[0048] In this embodiment, two transverse drive rods and two longitudinal drive rods are provided respectively. By rotating the drive source, the horizontal or / and vertical scaling of the telescopic mechanism is realized. When there is one drive source, that is, one drive source is connected to one drive motor, and one drive source can control two transverse drive rods and two longitudinal drives simultaneously to realize the scaling in two horizontal and vertical dimensions. When the telescopic mechanisms are combined to form a box, the telescopic mechanisms scale simultaneously to realize the expansion or contraction of the box volume and achieve the scaling in three dimensions. When the volume of the object to be stored is not very large, the scaling in only one dimension can meet the storage of the object. Two drive sources can be set, that is, two drive sources are respectively connected to two drive motors, and the two drive motors are arranged oppositely. One drive motor controls two transverse drive rods, and the other drive motor controls two longitudinal drive rods. According to the direction of the object placement, the scaling in one horizontal or vertical dimension is realized, so as to better meet the usage requirements in different occasions.

[0049] A first pulley 4 is provided at the end of the transverse drive rod, and a second pulley 5 is provided at the end of the longitudinal drive rod. The size of the first pulley 4 is smaller than that of the second pulley 5.

[0050] A sliding groove 11 is provided in the cross sliding groove 10. The transverse drive rod and the longitudinal drive rod are respectively inserted into the sliding groove 11. Third pulleys 7 and fourth pulleys 14 are provided on the sliding groove 11. The third pulleys 7 are in sliding fit with the longitudinal drive rod, and the fourth pulleys 14 are in sliding fit with the transverse drive rod.

[0051] At least one drive source 6 is provided. A single drive source can realize the simultaneous scaling in two horizontal and vertical dimensions and the three-dimensional simultaneous scaling when combined to form a polyhedron. When there are two drive sources, the two drive sources respectively control one dimension for scaling, and when the two drive sources work simultaneously, multi-dimensional scaling is realized.

[0052] The drive source 6 is connected to the output shaft of the drive motor 13. The drive motor 13 is a servo motor.

[0053] As Figure 7 and Figure 8 shown, a box is composed of a multi-dimensional synchronous telescopic mechanism. When the telescopic mechanisms are used to form a box, each telescopic mechanism forms a box surface of the box. The corner connecting piece 1 is replaced by a corner tee 15, and adjacent box surfaces are connected by the corner tee 15. The motors on each box surface are connected in parallel through power lines and are ensured to be powered simultaneously to realize the simultaneous telescoping of each telescopic mechanism, so as to realize boxes of different volumes.

[0054] In summary, by controlling the lateral drive rod or the longitudinal drive rod, one-dimensional scaling of the telescopic mechanism is achieved. By controlling the simultaneous movement of the lateral drive rod and the longitudinal drive rod, two-dimensional scaling of the telescopic mechanism is achieved. By combining the telescopic mechanisms to form a box body, with each telescopic mechanism serving as a box surface of the box body, when each telescopic mechanism moves simultaneously, three-dimensional scaling of the box body is achieved. The overall operation is convenient and space is saved.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
