Description

Technical Field

[0001] The utility model relates to the field of electronic devices, in particular to a fixed power-taking integrated connection structure and an information display screen. Background Art

[0002] Under the background of the increasingly mature industrial production level nowadays, in production and operation places such as convenience stores, banks, hospitals, offices, etc., there is a greater tendency to use electronic devices with display screens. The display screen can be used to display information, and the information can be changed according to needs. In the context of the increasingly reduced price cost, it gradually replaces traditional paper products for displaying information. Such an electronic device with a display screen can be an information display screen, which can display information such as product names, prices, discounts, etc. The basic components of the existing information display screen can include a display screen, a processor unit, and a power supply unit. Among them, the display screen is used to display information, the processor unit is used to control and transmit information to the display screen, and the power supply unit is used to supply power to the processor unit and the display screen. The existing power supply methods mainly include battery power supply and external power supply. The common external power supply generally needs to be connected through a power adapter and a power cord, and the display screen not only needs to be powered, but also needs to be fixed. Usually, brackets and tracks are used to fix the display screen. At this time, if the power cord is directly connected, it is less beautiful. Therefore, the existing technology adopts an integrated solution for fixing and power supply, and connects the information display screen to the track with a power supply structure through a connector to achieve power supply and fixation at the same time.

[0003] The applicant previously applied for a patent with the publication number CN114976796A and the title of an invention patent for an easily detachable track electrical connection structure and an information display screen. The inner-rail connection block and the information screen of this invention are respectively fixed by screws and powered through a power interface. In scenarios where it is not necessary to perform communication configuration on the information screen through the power interface, this fixing and power-taking method is relatively redundant and costly.

[0012] Further, it further includes a clamping mechanism, which is disposed on the connection block, and the connection block is clamped in the track through the clamping mechanism.

[0013] Different from the prior art, the above technical solution uses a connection block to be snap-connected to the track and obtain power. A first connection hole and a first electrical connection member are provided in the connection block, a second connection hole and a second electrical connection member are provided on the electrical device, and a conductive screw sequentially passes through the first connection hole and the second connection hole and is threadedly connected and fastened to a conductive nut.

[0034] Please refer to Figures 1 to 9 , this embodiment provides a fixed power-taking integrated connection structure, including a connection block 10, a conductive screw 20, a conductive nut 21, a first electrical connection member 22, and a second electrical connection member 23. The conductive screw 20, the conductive nut 21, the first electrical connection member 22, and the second electrical connection member 23 can all be made of metal conductive materials, such as iron, copper, etc. The connection block 10 is used to connect with the electrical device, that is, the electrical device can be first fixedly connected and electrically connected to the connection block 10, and then the connection block 10 is snap-connected and electrically connected to the rail 2 that plays a fixing role, so as to fix the electrical device below the rail 2 and obtain power. The inside of the connection block 10 is provided with a first electrical connection member 22 and a first connection hole 24. One surface of the electrical device connected to the connection block 10 is provided with a second connection hole 25. Refer to Figure 1For example 3, the second connection hole 25 is provided on the top surface of the display screen. The conductive screw 20 sequentially passes through the first connection hole 24 and the second connection hole 25 and is then threadedly connected and fastened to the conductive nut 21; one end of the first electrical connection member 22 is provided between the head of the conductive screw 20 and the first connection hole 24, and the other end is used for electrical connection with an external power supply device, where the external power supply device refers to devices such as the track 2 with a conductive strip, a power adapter, etc. that can provide power. One end of the second electrical connection member 23 is provided between the conductive nut 21 and the second connection hole 25, and the other end is used for electrical connection with the electrical device. It should be noted that the structures of the first electrical connection member 22 and the second electrical connection member 23 can be conductive wires or conductive elastic pieces. When a conductive wire is selected, the conductive wire can be wound around the screw and fixed by the fastening of the screw nut. When a conductive elastic piece is selected, a notch or hole for the screw to pass through can be provided at one end of the conductive elastic piece and fixed by the fastening of the screw nut.

[0035] The electrical device can be a speaker, a display screen, a lamp, etc., and the power supply device can be a storage battery, a wire, or the conductive strip 202 in the track 2. In this embodiment, the electrical device is a display screen and the power supply device is the power supply track 2 for illustration.

[0036] The connection block 10 is used for snap connection with the track 2. The connection block 10 and the track 2 can be snap-connected only for fixing purposes, and then power is obtained by externally connecting a wire to a power supply, or electrical connection is made while fixing. Specifically, a conductive strip 202 can be provided in the track 2, and the first electrical connection member 22 is provided inside the connection block 10. One end of the first electrical connection member 22 for electrical connection with an external power supply device extends outside the connection block 10, and the two are configured such that when the connection block 10 is snap-connected into the track 2, the first electrical connection member 22 contacts the conductive strip 202 to form an electrical connection.

[0037] Preferably, the first electrical connection member 22 is a conductive elastic sheet. One end of the first electrical connection member 22 is a sheet portion, and an opening not smaller than the first connection hole 24 is formed in the sheet portion. During assembly, one end of the first electrical connection member 22 is disposed above the first connection hole 24. The tail of the conductive screw 20 passes through the opening at one end of the first electrical connection member 22 and is inserted into the first connection hole 24, and then threaded and tightened. At this time, the screw head of the conductive screw 20 can tightly press one end of the first electrical connection member 22 to maintain a stable electrical connection. The other end of the first electrical connection member 22 can extend to the outer side of the upper surface or the front and rear surfaces of the connection block 10 and be electrically connected to the conductive strip 202 in the track 2, thereby completing the power-taking process in sequence from the conductive strip 202 in the track 2, the first electrical connection member 22, and the conductive screw 20. After passing through the first connection hole 24, the conductive screw 20 continues to be inserted into the second connection hole 25. The second electrical connection member 23 can be made of the same conductive elastic sheet as the aforementioned first electrical connection member 22 (i.e., a sheet portion with an opening at one end) and is disposed below the second connection hole 25, while the conductive nut 21 is disposed below one end of the second electrical connection member 23. After the conductive screw 20 passes through the second connection hole 25 and one end of the second electrical connection member 23 in sequence and is threadedly connected and tightened with the conductive nut 21, the conductive nut 21 can press one end of the second electrical connection member 23 to maintain a stable electrical connection. The other end of the second electrical connection member 23 can extend to the inside of the electrical device and be electrically connected to the conductive end. The conductive end is used to access the power supply and can be disposed on the circuit board. Thus, the power-taking process in sequence from the conductive screw 20, the second electrical connection member 23, and the electrical device is completed. Combining the above text, a structure of integrated fixing and power-taking connection can be formed.

[0038] This new type uses the connection block 10 to be snap-connected to the track 2 to obtain power. The first connection hole 24 and the first electrical connection member 22 are provided in the connection block 10, the second connection hole 25 and the second electrical connection member 23 are provided on the electrical device. The conductive screw 20 passes through the first connection hole 24 and the second connection hole 25 in sequence and is threadedly connected and tightened with the conductive nut 21, and the first electrical connection member 22 and the second electrical connection member 23 are respectively fixed in the connection block 10 and the electrical device. Through the cooperation of the conductive screw 20 and the conductive nut 21, the connection block 10 and the electrical device are fixed and powered, forming a structure of integrated fixed power-taking connection, without the need to additionally provide a power-taking terminal for the connection block 10 and a power-taking port for the electrical device, effectively saving the product cost.

[0039] In some embodiments, there is further a receiving groove 30, which is arranged below the second connection hole 25 and is used to receive and limit the conductive nut 21. The front side of the receiving groove 30 is open, and the conductive nut 21 can be snapped into the receiving groove 30. Preferably, the conductive nut 21 has at least one side plane, and the internal space of the receiving groove 30 is adapted to the conductive nut 21. After the conductive nut 21 is inserted into the receiving groove 30 from the front side opening, its side plane is in contact with the left, right or rear inner wall of the receiving groove 30. If only one side plane is in contact with one inner wall surface of the receiving groove 30, when the conductive screw 20 and the conductive nut 21 are rotated relatively for threaded connection, only a resistance needs to be given to the conductive nut 21 at the front side opening of the receiving groove 30 (for example, pressing with a finger), and then the conductive screw 20 can be screwed into the conductive nut 21. If two side planes are in contact with two inner wall surfaces of the receiving groove 30, the conductive screw 20 can be screwed into the conductive nut 21 without external force, which is easy and labor-saving and improves the assembly efficiency. On the other hand, the receiving groove 30 can also be used to pre-assemble the second electrical connection member 23. Only by making the second electrical connection member 23 into a structure matching the receiving groove 30, for example, the width of the second electrical connection member 23 is the same as or slightly smaller than the internal width of the receiving groove 30, the second electrical connection member 23 and the conductive nut 21 can be pre-loaded into the receiving groove 30, and then the conductive screw 20 is screwed into the conductive nut 21, improving the assembly efficiency.

[0040] Further, the second electrical connection member 23 is a metal wire, which is wound into a U shape, and the bottom of the U shape is inserted into the receiving groove 30. When the conductive screw 20 and the conductive nut 21 are rotated relatively for threaded connection, the conductive nut 21 moves upward and presses the metal wire. The metal wire can be made of conductive materials such as iron or copper. One end of the top of the U-shaped second electrical connection member 23 is electrically connected to the electrical device to provide power for the electrical device. Using a metal wire instead of a conductive elastic sheet can further save costs.

[0041] Further, a wire passing groove 301 is provided at the upper part of the front side of the receiving groove 30, and the metal wire can pass through the wire passing groove 301. The wire passing groove 301 can be an opening on the front side or a through groove, which can play a role in limiting the U-shaped conductive wire and improve the electrical connection stability.

[0042] Further, it further includes an angle adjustment connecting member 40. The upper part of the angle adjustment connecting member 40 is inserted into the inside of the connecting block 10 and is flip-connectable to the connecting block 10. The first connection hole 24 is provided on the angle adjustment connecting member 40. An opening for the angle adjustment connecting member 40 to pass through is formed on the bottom surface of the connecting block 10. The width of the opening in the flipping direction of the angle adjustment connecting member 40 should be greater than the width of the angle adjustment connecting member 40 to avoid being blocked when the angle adjustment connecting member 40 rotates. The angle adjustment connecting member 40 and the connecting block 10 can be hinged, and a damping member, such as rubber, can be provided at the hinge. A normal resistance is applied to the angle adjustment connecting member 40 through the damping member to fix its angle. When the angle needs to be adjusted, an external force greater than the resistance of the damping member is applied to rotate the angle adjustment connecting member 40 to the required position, and then the external force is removed. The normal resistance applied by the damping member will keep the angle adjustment connecting member 40 in the rotated position, thereby realizing the angle adjustment of the electrical device. The angle adjustment connecting member 40 and the connecting block 10 can also be connected by gear meshing. The rotation of the gear drives the rotation of the angle adjustment connecting member 40 to realize the angle adjustment of the electrical device.

[0043] The present invention also provides an information display screen, including a fixed power-taking integrated connection structure 1, a track 2, and an information screen 3. The fixed power-taking integrated connection structure 1 is the fixed power-taking integrated connection structure described in any one of the above embodiments. The track 2 is the external power supply device, and the information screen 3 is the electrical device. The connecting block 10 is placed in the track 2 and is electrically connected to the track 2 through the first electrical connection member 22. The information screen 3 is an existing screen for displaying content, such as an LCD or OLED screen.

[0044] Further, it further includes a clamping mechanism 4. The clamping mechanism 4 is arranged on the connecting block 10, and the connecting block 10 is clamped in the track 2 through the clamping mechanism 4. The clamping mechanism 4 can refer to the structure formed by the clamping member, movable member, etc. in Patent CN114976796A, and any structure in the prior art that can achieve the same or similar functions and effects is acceptable. The clamping mechanism 4 can only protrude from one side surface of the in-rail connecting block 10. In this case, the other side surface corresponding to the clamping mechanism 4 is closely attached to the inner wall surface of the other side of the track 2 to achieve clamping. The width inside the track 2 is slightly wider than the front and rear widths of the in-rail connecting block 10, so that the in-rail connecting block 10 is exactly located inside the track 2. In this way, as long as the clamping mechanism 4 on at least one side protrudes and is stuck in the card slot 201, the clamping of the in-rail connecting block 10 in the track 2 can be achieved. Preferably, there are two clamping mechanisms 4 on the front and rear two side surfaces of the in-rail connecting block 10. The two clamping blocks are respectively arranged at both ends of the in-rail connecting block 10 to avoid unstable shaking of the in-rail connecting block 10 after clamping, and the clamping is more stable. Preferably, the clamping mechanism 4 symmetrically protrudes from the two side surfaces of the in-rail connecting block 10, so there is no need to distinguish the installation direction, and the clamping can be carried out in both the correct and reverse installations, which is more convenient and fast. A card slot 201 is provided on the inner side wall of the track 2, and the clamping mechanism 4 can be clamped in the card slot 201 on the inner side wall of the track 2. The direction of the card slot 201 on the inner side wall of the track 2 extends parallel to the length direction of the track 2. Therefore, the clamping mechanism 4 can be clamped with the track 2 at any position, that is, the in-rail connecting block 10 can be installed at any position on the track 2.

[0045] It should be noted that although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, the changes and modifications made to the embodiments described in this article, or the equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
