Description

Technical Field

[0001] The utility model relates to the field of track power taking structures, in particular to a track power removing structure and an information display device with an improved service life. Background Art

[0002] Under the background of today's increasingly mature industrial production level, in production and operation places such as supermarkets, banks, hospitals, and offices, there is a greater tendency to use electronic devices with display screens. The display screens can be used to display information, and the information can be changed according to needs. In the context of the increasingly reduced price cost, they gradually replace traditional paper products for displaying information. Such electronic devices with display screens can be information display screens, which can display information such as product names, prices, discounts, etc. The basic components of existing information display screens generally 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. Existing power supply methods mainly include battery power supply and external power supply. 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 aesthetically pleasing. Therefore, the prior art adopts a scheme of integrating fixing and power supply, connecting the information display screen to a track with a power supply structure through a connecting piece to achieve power supply and fixing at the same time.

[0003] The applicant previously applied for a patent with the publication number CN114976796A, titled "An Easily Detachable Track Electrical Connection Structure and Information Display Device". In this invention, the conductive end is arranged in the middle of the top of the in-rail connection block, and the clamping member is arranged on the side surfaces of the two ends of the in-rail connection block. When the in-rail connection block is placed in the track, the clamping member and the conductive end are respectively subjected to opposite acting forces brought by the side wall and the top wall of the track. The horizontal distance between the clamping member and the conductive end is relatively long, and the torque is relatively large. Long-term stress may cause the in-rail connection block to produce bending deformation, resulting in poor contact between the conductive end and the conductive strip in the track, and inability to normally take power, so the service life of the power taking structure is not long. Utility Model Content

[0004] Therefore, it is necessary to provide a track power taking structure and an information display device with an improved service life to solve the problem that in the prior art, the conductive end of the in-rail connection block is arranged in the middle of the top of the in-rail connection block, and the clamping member is arranged on the side surfaces of the two ends of the in-rail connection block. When the in-rail connection block is placed in the track, the clamping member and the conductive end are respectively subjected to opposite acting forces brought by the side wall and the top wall of the track. Long-term stress may cause the in-rail connection block to bend, resulting in poor contact between the conductive end and the conductive strip in the track, and inability to normally take power, so the service life of the power taking structure is not long.

[0011] Further, the electrical device is an information screen, a speaker, or a lamp.

[0012] Further, the in-rail connection block includes a lower main body and an upper cover body. A damping portion is provided on the lower bottom surface of the upper cover body.

[0037] Please refer to Figures 1 to 10 , this embodiment provides an in-rail power-taking structure 1 with an increased service life, including an in-rail connection block 10, a clamping member 20, a conductive elastic sheet 40, and a device connection member 30; the clamping member 20 is respectively arranged on the side surfaces of both ends of the in-rail connection block 10, and the conductive elastic sheet 40 is arranged on the top surface of the in-rail connection block 10 and is respectively close to the clamping member 20; the in-rail connection block 10 is fixed in the track 2 through the clamping member 20; the device connection member 30 is arranged at the bottom of the in-rail connection block 10 and is used for fixedly connecting with an electrical device and forming an electrical connection, one end of the conductive elastic sheet 40 forms an electrical connection with the device connection member 30, and the other end is electrically connected to the conductive bar 22 in the track 2.

[0038] The clamping member 203 protrudes from the side surface of the in-rail connection block 10 and is used for clamping the inner side wall of the track 2. The clamping member 203 may only protrude from one side surface of the in-rail connection block 10. In this case, the other side surface corresponding to the clamping member 203 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-to-back width of the in-rail connection block 10, so that the in-rail connection block 10 is exactly located inside the track 2. As long as the clamping member 203 on at least one side protrudes and is stuck in the card slot 21, the in-rail connection block 10 can be clamped inside the track 2. Preferably, there are two clamping members 203 on the front and rear side surfaces of the in-rail connection block 10. The two clamping members are respectively arranged at both ends of the in-rail connection block 10 to avoid unstable shaking of the in-rail connection block 10 after clamping and make the clamping more stable. Preferably, the clamping members 203 symmetrically protrude from both side surfaces of the in-rail connection block 10, so there is no need to distinguish the installation direction, and clamping can be carried out whether it is installed correctly or reversely, which is more convenient and fast. The inner side wall of the track 2 is provided with a card slot 21. The clamping member 203 can be clamped in the card slot 21 on the inner side wall of the track 2. The direction of the card slot 21 on the inner side wall of the track 2 extends parallel to the length direction of the track 2. Therefore, the clamping member 203 can be clamped with the track 2 at any position, that is, the in-rail connection block 10 can be installed at any position on the track 2.

[0039] The conductive elastic sheet 40 is a metal elastic sheet, such as a copper sheet. A conductive strip 22 is arranged inside the track 2. When the in-rail connection block 10 is placed inside the track 2, the conductive elastic sheet 40 is electrically connected to the conductive strip 22. The clamping member 20 is a convex block protruding from the side surface of the in-rail connection block 10. The clamping member 20 can be fixed on the side surface of the in-rail connection block 10 and can be installed to slide in from one end entrance of the track 2, or the track 2 has a certain elasticity, and clamping can be achieved. The clamping member 20 can also be configured to be telescopic inside and outside the in-rail connection block 10. For the specific structure, reference can be made to Patent CN114976796A. A detachable clamping structure is formed by driving the clamping member 20 through a movable member.

[0040] Since the in-rail connection block 10 has a certain length, a plurality of the clamping members 20 are provided, and the plurality of the clamping members 20 are evenly distributed at both ends of the in-rail connection block 10. By clamping the clamping members 20 at both ends into the track 2, the in-rail connection block 10 can be stably placed into the track 2. Correspondingly, there are two conductive elastic sheets 40. The two conductive elastic sheets 40 can both be close to the clamping members 20 at the same end. In order to improve the structural stability and optimize the internal space of the in-rail connection block 10, the two conductive elastic sheets 40 can be respectively close to the two clamping members 20 at both ends. Preferably, in the direction perpendicular to the length of the track 2, the two conductive elastic sheets 40 and the two clamping members 20 at both ends are in the same plane. In this setting, there is no moment between the conductive elastic sheet 40 and the clamping member 20, which can ensure to the greatest extent that the in-rail connecting member between the two is less likely to bend, thereby ensuring the stable electrical connection between the conductive elastic sheet 40 and the conductive bar 22 in the track 2.

[0041] In this new type, the clamping members 20 are respectively arranged on the side surfaces of both ends of the in-rail connection block 10, and the conductive elastic sheets 40 are arranged on the top surface of the in-rail connection block 10 and are respectively close to the clamping members 20, so as to reduce the moment between the conductive elastic sheets 40 and the clamping members 20 on the in-rail connection block 10, reduce the influence on the connection between the conductive elastic sheets 40 and the conductive bar 22 in the track 2 caused by the bending of the in-rail connection block 10 itself during long-term use, avoid poor contact between the conductive elastic sheets 40 and the conductive bar 22 in the track 2, and improve the electrical connection stability.

[0042] In some embodiments, the device connecting member 30 and the in-rail connection block 10 are rotatably connected, and the rotatable connection methods include hinge connection, gear meshing connection and other methods. Considering the manufacturing cost, a pair of circular grooves can also be arranged in the in-rail connection block 10. The two ends of the device connecting member 30 are configured as cylinders and are respectively placed into the circular grooves. By limiting the top of the device connecting member 30, the device connecting member 30 can realize the rotation of the device connecting member 30 relative to the in-rail connection block 10 through the relative movement of the cylinders at both ends and the circular grooves. The line connecting the centers of the pair of circular grooves is collinear with the rotation axis of the device connecting member 30. Further, in order to provide damping by using the structure of the electrical connection member itself, on the one hand, the device connecting member 30 can be adjusted in angle in some use scenarios, and on the other hand, not too much cost is increased. The conductive elastic sheet 40 includes a first elastic sheet 405 and a second elastic sheet 406; the first elastic sheet 405 is fixed in the in-rail connection block 10 and is electrically connected to the conductive bar 22 in the track 2 at one end; the second elastic sheet 406 is fixed at the end of the rotation axis of the device connecting member 30, and one end of the second elastic sheet 406 is electrically connected to the electrical device; the other end of the first elastic sheet 405 and the other end of the second elastic sheet 406 exert elastic forces on each other to form damping. Refer to Figure 8, the other end of the first elastic piece 405 is a V / U-shaped elastic piece, and the other end of the second elastic piece 406 is configured as a protrusion. After pressing the device connecting block into the in-rail connecting block 10, the second elastic piece 406 extrudes the end of the first elastic piece 405 outward, so that the first elastic piece 405 obtains elastic potential energy. Furthermore, the first elastic piece 405 generates an elastic force on the second elastic piece 406, and this elastic force can play a certain damping role. The interaction force between the first elastic piece 405 and the second elastic piece 406 can make the device connecting piece 30 maintain its position after rotation. It should be noted that the damping magnitude obtained through this structure can be proportional to the elastic force magnitude between the first elastic piece 405 and the second elastic piece 406. In actual use, the damping magnitude can be set within a reasonable range. For example, when the device connecting block is connected to a relatively light-weight audio or lamp, after rotating the angle, the gravity brought by the self-weight of the audio or lamp is less than the resistance between the first elastic piece 405 and the second elastic piece 406, then the angle can be maintained; when the device connecting block is connected to a relatively heavy information screen 3, after rotating the angle, the gravity brought by the self-weight of the information screen 3 is greater than the resistance between the first elastic piece 405 and the second elastic piece 406, then it can automatically return to the vertical state.

[0043] In some embodiments, damping can also be added to other parts of the in-rail connecting block 10 to realize the angle adjustment of an electric device with a larger mass. Specifically, the in-rail connecting block 10 includes a lower main body 101 and an upper cover 102. The lower bottom surface of the upper cover 102 is provided with a damping portion 1021. The damping portion 1021 can be made of materials such as rubber or silica gel with a certain thickness. When the upper cover 102 is covered with the lower main body 101, the damping portion 1021 generates damping on the top of the device connecting piece 30. The principle is that the top of the device connecting piece 30 extrudes the damping portion 1021, and both the elastic restoring force and the surface friction force of the damping portion 1021 itself can bring resistance to the device connecting piece 30. When not applying a large enough external force to the device connecting piece 30, the resistance can prevent the device connecting piece 30 from rotating. By configuring a damping portion 1021 with a larger thickness, greater elasticity, and a larger surface friction coefficient, the angle adjustment of an electric device with a larger mass can be realized.

[0044] Furthermore, the lower bottom surface of the upper cover 102 is provided with a reinforcing rib 1022, and the damping portion 1021 is arranged at the lower edge of the reinforcing rib 1022. The reinforcing rib 1022 can increase the structural strength of the in-rail connecting block 10. By arranging the damping portion 1021 at the lower edge of the reinforcing rib 1022, the thickness of the damping portion 1021 can be reduced while ensuring the same damping, thereby reducing costs.

[0045] The present novelty also provides an information display device, including a track power-taking structure 1, a track 2, and an information screen 3. The track power-taking structure 1 is a track power-taking structure 1 for improving lifespan as described in any of the above embodiments. The in-track connection block 10 of the track power-taking structure 1 is disposed within the track 2 and electrically connected to the track 2. The device connection member 30 of the track power-taking structure 1 is fixedly connected and electrically connected to the information screen 3. The information screen 3 is an electronic display screen, and the information screen 3 further includes a circuit board (such as a PCB board). The circuit board is provided with a processor (which can be a single-chip microcomputer) and a power supply unit (such as a voltage conversion chip). The electronic display screen (such as a liquid crystal screen or an OLED screen, etc.) is connected to the processor, and the power supply unit is connected to the power supply terminals of the electronic display screen and the processor. The power supply unit is electrically connected to the track 2 through the track power-taking structure 1. The in-track connection block 10 and the track 2 can refer to the in-track connection block 10 in the patent with the publication number CN114976796A, but are not limited to the specific structure in this reference patent. Any structure in the prior art that can achieve the same or similar functions and effects can be adopted.
