Description

[Technical field]

[0001] The invention relates to a lifting table controller and a lifting table frame with outer wiring, belonging to the technical field of lifting table accessories. [Background technology]

[0002] Tables are daily furniture widely used by people in work, study and life. There are many types of existing tables, such as computer tables, study tables, office desks, etc. As people's quality of life continues to improve, the requirements for the comfort and convenience of tables are also getting higher and higher. Therefore, in order to meet the requirements of users of different heights, a height-adjustable lifting table has appeared on the market. In order to make it more convenient for people to operate, the lifting table in the existing technology has added an electric lifting function, that is, an electric lifting table.

[0003] The basic structure of the current electric lift table includes a table top, a crossbeam is arranged under the table top, and lifting columns are arranged on both sides of the table top. Usually, a control box is arranged in the crossbeam, and the control box is used to control the lifting columns on both sides. When the power interface is on the same side of the controller, the wiring of the power cord, manual control line and other wiring harnesses is in a messy state, which makes it easy for the wiring harnesses to be entangled with each other, thereby affecting the normal connection of the wiring harnesses and reducing the overall aesthetics. In the prior art, such as the European invention patent EP2452589B1, a controller with a guide groove is disclosed. The patent solves the above problem by setting a guide groove on the top of the controller to guide the wiring of the column power cord.

[0004] However, since the guide groove is located at the top of the controller, the height of the controller itself is greatly increased, making the controller thicker and heavier. In addition, since the controller is usually fixedly connected to the beam through its top, locating the guide groove at the top of the controller will affect the setting of the controller mounting components and increase the difficulty of loading and unloading the controller. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is a lifting table controller with outer wiring, which realizes the guidance of the wire harness without affecting the height of the controller itself.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A lifting table controller with outer wiring, the controller is arranged between two lifting columns, the controller controls the lifting and lowering of the lifting columns, a crossbeam for supporting and fixing is arranged between the lifting columns, the controller is arranged in the crossbeam, at least two line interfaces are arranged on a side of the controller close to one of the lifting columns, and a wiring channel for guiding a wiring harness is arranged on an outer side wall of the controller corresponding to the inner side wall of the crossbeam.

[0008] The beneficial effects of adopting the present invention are:

[0009] In the present invention, a wiring channel for guiding the wiring harness is provided on the outer wall of the controller corresponding to the inner wall of the beam. Providing the wiring channel on the outer wall of the controller can avoid increasing the height of the controller itself, making the controller appear lighter, reducing the volume of the controller exposed outside the beam, reducing the possibility of damage to the controller, and improving its overall aesthetics. At the same time, the actual space below the controller will not be reduced, which provides convenience for the design of the subsequent columns.

[0010] Secondly, since the controller is usually fixedly connected to the crossbeam through its top, the wiring channel is arranged on the outer wall of the controller, which can avoid conflict between the wiring channel of the controller and the installation components. At the same time, the wiring channel does not need to be specifically designed and manufactured to avoid the installation components, which reduces the restrictions on the wiring channel and makes its structure simpler.

[0011] Preferably, the wiring channel includes an open end, and the opening direction of the open end is upward. The open end can more conveniently install the wiring harness into the wiring channel, so that the wiring harness is not easy to escape from the wiring channel, thereby improving the stability of the wiring harness.

[0012] Preferably, the inner side wall of the cross beam blocks the open end, and the inner side wall of the cross beam blocks the open end so that the wiring harness will not escape from the wiring channel, thereby improving the stability of the wiring harness.

[0013] Preferably, the outer side wall of the controller is concave to form the wiring channel, and the wiring channel is formed by the concave outer side wall of the controller and will not affect the overall width of the controller.

[0014] Preferably, the wiring channel includes a baffle for limiting horizontal escape of the wiring harness.

[0015] Preferably, the controller comprises an upper shell and a lower shell, and the wiring channel is arranged on the outer side wall of the upper shell.

[0016] Preferably, the controller comprises an upper shell and a lower shell, the crossbeam comprises an inner groove for accommodating the controller, and the lower shell of the controller faces the top of the inner groove.

[0017] Preferably, the controller is provided with fixing holes for screws to pass through, and the controller is fixed by screws.

[0018] Preferably, the controller is provided with a cover plate for covering the fixing holes, and the fixing holes on the controller are shielded by the cover plate to prevent foreign objects from entering the fixing holes, while improving the aesthetics of the controller.

[0019] The present invention also discloses a lifting table frame, comprising a crossbeam, lifting columns installed on both sides of the crossbeam and a controller installed in the crossbeam, wherein the controller controls the lifting of the lifting columns, and the controller adopts any one of the controllers described above.

[0020] Other features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0029] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0030] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate orientation or position relationship are based on the orientation or position relationship shown in the drawings and are only for the convenience of describing the embodiments and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] Embodiment 1:

[0032] like Figures 1 to 4As shown, this embodiment shows a lifting table controller with an outer wiring, wherein the controller 1 is arranged between two lifting columns 3, and the controller 1 controls the lifting and lowering of the lifting columns 3, and a crossbeam 2 for supporting and fixing is arranged between the lifting columns 3 (refer to Figure 5 ), the controller 1 is arranged in the beam 2, and at least two line interfaces 103 are arranged on one side of the controller 1 close to one of the lifting columns 3, and a wiring channel 101 for guiding the wiring harness 13 is arranged on the outer wall of the controller 1 that contacts the inner wall of the beam 2.

[0033] In this embodiment, at least two line interfaces 103 are provided on the same side of the controller 1, including the line interfaces 103 of the lifting columns 3 on both sides of the controller 1. The outer wall of the controller 1 corresponding to the inner wall of the beam 2 is provided with a wiring channel 101 for guiding the wiring harness 13. The wiring channel 101 guides the wiring harness 13 of one of the lifting columns 3 to the other side of the controller 1. In addition, the wiring channel 101 is provided on the outer wall of the controller 1, which can avoid the increase of the height of the controller 1 itself, making the controller 1 appear lighter, reducing the volume of the controller 1 exposed outside the beam 2, reducing the possibility of damage to the controller 1, and improving its overall aesthetics. At the same time, the actual space below the controller 1 will not be reduced, which provides convenience for the design of the later columns.

[0034] Secondly, since the controller 1 is usually fixedly connected to the crossbeam 2 through its top, the wiring channel 101 is arranged on the outer wall of the controller 1, which can avoid the wiring channel 101 of the controller 1 from conflicting with the installation components. At the same time, the wiring channel 101 does not need to be specifically designed and manufactured to avoid the installation components, so that the wiring channel 101 has fewer restrictions and its structure can be simpler.

[0035] In order to facilitate the installation of the wiring harness 13, the wiring channel 101 in the present embodiment includes an open end, and the opening direction of the open end of the wiring channel 101 is upward. The wiring harness 13 can be directly loaded into the wiring channel 101 through the open end, making the installation of the wiring harness 13 more convenient. In addition, the upward opening direction of the open end constrains the wiring harness 13, which can prevent the wiring harness 13 from falling and improve the stability of the wiring harness 13.

[0036] In order to further improve the stability of the wiring harness 13, the inner wall of the beam 2 in this embodiment blocks the open end. By blocking the open end through the inner wall of the beam 2, the wiring harness 13 will not separate from the wiring channel 101 after the controller 1 is installed, thereby improving the stability of the wiring harness 13.

[0037] In addition, the wiring channel 101 includes a baffle 105 for limiting the horizontal detachment of the wiring harness 13. Under the action of the baffle 105, it is ensured that the wiring harness 13 will not automatically detach from the wiring channel 101. At the same time, the wiring channel 101 has a sufficient depth to accommodate multiple wiring harnesses 13, so that the wiring harnesses 13 in the controller 1 can be arranged more neatly and smoothly, and the phenomenon of entanglement between the wiring harnesses 13 can be avoided, thereby improving the safety and overall aesthetics of the wiring harness 13.

[0038] In order to keep the overall width of the controller 1 intact, the wiring channel 101 described in this embodiment is formed by the concave outer wall of the controller 1, so that the width of the controller 1 can correspond to the width inside the beam 2. When the internal width of the beam 2 remains unchanged, the controller 1 can have a large enough space, reducing the difficulty of designing the internal electrical components of the controller 1.

[0039] There may be different embodiments for the specific position of the wiring channel 101. In this embodiment, the controller 1 includes an upper shell 10 and a lower shell 11. The wiring channel 101 is arranged on the outer wall of the upper shell 10. Since some electrical components need to be installed inside the controller 1, the upper shell 10 of the controller 1 is provided with a cavity for accommodating the electrical components. Therefore, the height of the upper shell 10 of the controller 1 is much greater than the height of the lower shell 11 of the controller 1. Therefore, there is enough space on the outer wall of the upper shell 10 of the controller 1 for laying the wiring channel 101, and there is less restriction on the wiring channel 101.

[0040] Regarding the installation of the controller 1, the controller 1 in this embodiment includes an upper shell 10 and a lower shell 11, and the crossbeam 2 includes an inner groove for accommodating the controller 1. The lower shell 11 of the controller 1 faces the top of the inner groove. The controller 1 is provided with a fixing hole 102 for screws to pass through. The fixing hole 102 passes through the upper shell 10 and the lower shell 11 of the controller 1. The controller 1 is fixed by screws. The controller 1 can be fixed to the bottom of the table top, and of course it can also be fixed to the crossbeam 2. If it is fixed to the crossbeam 2, it is preferred to set a corresponding fixing plate on the crossbeam 2. In addition, in order to improve the aesthetics of the controller 1, the surface of the upper shell 10 of the controller 1 in this embodiment is provided with a cover plate 104 for covering the fixing hole 102. The cover plate 104 blocks the fixing hole 102 left on the surface of the controller 1 to prevent foreign matter from entering the fixing hole 102, while improving the overall aesthetics of the controller 1.
