Description

Technical Field

[0001] The present invention relates to the technical field of power-taking equipment, and in particular to a track power-taking device with adjustable angle. Background Art

[0002] When installing the rail power terminal, in order to adapt to the horizontal or vertical display mode of the terminal, the usual practice is to install the power supply track horizontally or vertically to enable the terminal to smoothly draw power. However, in some places, due to the limitations of installation conditions or installation space, the installation track cannot be rotated, making it difficult to switch the angle of power supply. Secondly, in order to allow the terminal to be tightly and firmly connected to the power supply track, the connecting power supply mechanism between the terminal and the track is usually tightly matched and not easy to disassemble to ensure that it is firmly fixed and will not vibrate, shake, or shift. At the same time, in order to facilitate the installation of the power supply mechanism, the device usually adopts a snap-on structure, which is easy to install but not easy to remove. Therefore, when switching the angle, it is very difficult to switch by removing the power supply mechanism. Usually, the angle switching is achieved by changing the angle of the power supply track. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a track power supply device with adjustable angle, so that the angle switching of the track power supply terminal is more convenient.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a track power supply device with adjustable angle, comprising a terminal fixing fastener and a power supply mechanism;

[0005] The power taking mechanism can be rotatably arranged on one side of the terminal fixing fastener;

[0006] The other side of the terminal fixing fastener away from the power taking mechanism is used to be fixedly arranged on the back side of the device to be powered;

[0007] The power taking mechanism always maintains an electrical connection with the device to be powered during the rotation process.

[0008] The beneficial effects of the present invention are as follows: the present invention provides a track power supply device with adjustable angle, comprising a terminal fixing fastener and a power supply mechanism; the power supply mechanism can be rotatably arranged on one side of the terminal fixing fastener; the other side of the terminal fixing fastener away from the power supply mechanism is used to be fixedly arranged on the back of the device to be powered; the power supply mechanism always maintains an electrical connection with the device to be powered during the rotation process.

[0016] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 5 , a track power supply device with adjustable angle, comprising a terminal fixing fastener and a power supply mechanism;

[0018] The power taking mechanism can be rotatably arranged on one side of the terminal fixing fastener;

[0019] The other side of the terminal fixing fastener away from the power taking mechanism is used to be fixedly arranged on the back side of the device to be powered;

[0020] The power taking mechanism always maintains an electrical connection with the device to be powered during the rotation process.

[0021] From the above description, it can be seen that the beneficial effects of the present invention are: the present invention provides a track power supply device with adjustable angle, including a terminal fixing clip and a power supply mechanism; the power supply mechanism can be rotatably arranged on one side of the terminal fixing clip; the other side of the terminal fixing clip away from the power supply mechanism is used to be fixedly arranged on the back of the device to be powered; the power supply mechanism always maintains an electrical connection with the device to be powered during the rotation process. When the device to be powered needs to switch the angle, since the power supply mechanism always maintains an electrical connection with the device to be powered and can rotate freely, the screen angle can be switched by directly rotating the device to be powered by the corresponding angle. This device can meet the normal power supply requirements of the device to be powered at various angles without changing the arrangement of the power supply track or removing the power supply mechanism.

[0022] Furthermore, it also includes a circuit board, two probes and two metal sheets;

[0023] The circuit board is fixedly arranged on a surface of the power taking mechanism close to the terminal fixing fastener;

[0024] The two probes are arranged at the bottom of the circuit board and are slidably electrically connected to the circuit board;

[0025] The two metal sheets are arranged on top of the circuit board, and the bodies of the two metal sheets are fixedly connected to the circuit board;

[0026] The two probes are electrically connected to the two metal sheets respectively through the circuit board;

[0027] The output ends of the two probes are electrically connected to the positive and negative electrodes of the device to be powered respectively;

[0028] The two metal sheets are electrically connected to the two metal conductors of the power supply track respectively.

[0029] As can be seen from the above description, the circuit board not only serves to fix the probe and the metal sheet, but also serves to electrically connect the metal sheet and the probe.

[0030] Furthermore, the geometric center of the circuit board coincides with the rotation axis of the power taking mechanism;

[0031] The two metal sheets are centrally symmetrical about the geometric center of the circuit board;

[0032] The two metal sheets are elastic.

[0033] As can be seen from the above description, the elasticity of the metal sheet is utilized to ensure the reliability of the contact between the metal sheet and the power supply track, thereby ensuring the stability of electrical conduction.

[0034] Furthermore, a conversion circuit is provided on a surface of the circuit board close to the terminal fixing fastener;

[0035] The conversion circuit includes a conductive contact and a conductive ring belt;

[0036] The conductive contact is arranged at the position where the geometric center of the circuit board is located;

[0037] The center of the conductive ring coincides with the location of the conductive contact;

[0038] One of the probes coincides with the geometric center of the circuit board; the other probe is spaced a preset distance from the geometric center of the circuit board;

[0039] The preset distance is equal to the radius of the conductive ring belt.

[0040] As can be seen from the above description, the arrangement of the conductive ring belt and the conductive contacts can better ensure that the power taking mechanism always maintains electrical connection with the device to be powered no matter how the device to be powered rotates.

[0041] Furthermore, the end of the probe is provided with an elastic telescopic structure.

[0042] As can be seen from the above description, the probe is configured as an elastically retractable structure in order to ensure that the probe is in contact with the conductive contact or the conductive ring belt, thereby ensuring the stability of the conduction.

[0043] Furthermore, the terminal fixing fastener is provided with a clearance hole for rotational engagement of the power taking mechanism;

[0044] A first limit buckle and a plurality of second limit buckles are provided on a surface of the power taking mechanism close to the terminal fixing buckle;

[0045] A plurality of the second limit buckles are arranged around the rotation axis of the power taking mechanism at intervals of preset angles;

[0046] The inner wall of the clearance hole is provided with an annular clearance groove for clamping the first limiting buckle and the second limiting buckle;

[0047] The annular relief groove is provided with a plurality of slots adapted to the first limiting buckle;

[0048] The plurality of slots are arranged at preset angles around the rotation axis of the power taking mechanism.

[0049] From the above description, it can be seen that the first limit buckle and multiple second limit buckles are respectively engaged with the annular clearance groove to realize axial positioning of the device to be powered and the power supply mechanism; the engagement of the first limit buckle and the slot realizes circumferential positioning of the device to be powered and the power supply mechanism, so that the device to be powered can remain stable after the angle conversion is completed.

[0050] Furthermore, the power taking mechanism is provided with a rotation limiting portion;

[0051] The rotation limiting portion is used for circumferential positioning of the power taking mechanism and the power supply track.

[0052] It can be seen from the above description that the setting of the rotation limiter is used to achieve a detachable connection between the power taking mechanism and the power supply track.

[0053] Furthermore, the cross section of the rotation limiting portion is spindle-shaped;

[0054] The shuttle-shaped rotation limiting portion limits the rotation angle of the power taking mechanism in the power supply track to 90 degrees.

[0055] It can be seen from the above description that the rotation limit portion with a shuttle-shaped cross section can ensure that the power taking mechanism can be connected to or removed from the power supply track by rotating 90 degrees.

[0056] How to use and working principle of this device: This device can be converted to any angle. Here we take the horizontal and vertical screen conversion as an example to illustrate the working principle.

[0057] First, the power supply mechanism is fixed to the device to be powered. The first and second limit snaps are engaged with the annular clearance groove on the terminal fixing snap. The first limit snap is engaged with the slot in the annular clearance groove, so that the power supply mechanism needs a certain force to rotate relative to the device to be powered in order to satisfy the first limit snap from the slot. After the above steps are completed, the connection direction of the two metal sheets on the power supply mechanism is parallel to the direction of the power supply track, and the power supply track is installed so that the rotation limit part on the power supply mechanism is engaged with the power supply track. Then, the power supply mechanism with the device to be powered is rotated 90 degrees as a whole (the rotation direction is determined by the position of the arc edge of the rotation limit part) so that the connection direction of the two metal sheets is perpendicular to the direction of the power supply track, that is, the metal sheets contact the metal conductors on the side walls of the power supply track to achieve power supply. When the device to be powered needs to be switched between landscape and portrait positions, the device to be powered is rotated 90 degrees (the rotation direction is the same as the rotation direction of the power supply mechanism when it is installed on the power supply track) to achieve the landscape and portrait switching.

[0058] During the switching process between landscape and portrait orientations of the device to be powered, the right-angled edge of the rotation limiter contacts the power rail, preventing relative rotation between the power supply mechanism and the power rail. This allows the first limiter to disengage from the slot, allowing the device to be powered to rotate. During this rotation, the conductive contacts and the conductive ring remain electrically connected to the two probes on the device to be powered, ensuring continuous power supply during the switching process.

[0059] When the power taking mechanism needs to be removed from the power supply track, it only needs to be rotated (the rotation direction is opposite to the rotation direction during installation) to remove it from the power supply track.
