[0045] The core of the present invention is to provide a mobile screen power supply base, which can realize the rapid installation of the battery box 3, and the operation is simple, convenient and fast. Another core of the present invention is to provide a display device including the mobile screen power supply base, which is easy to assemble.

[0046] Please refer to Figures 1 to 5 A power supply base for a mobile screen includes a base 1, a battery box 3 and a quick-release structure 5.

[0047] Specifically, the base 1 is provided with a limiting protrusion 11 connected to the outer end surface of the base 1, and a socket 12 and a card male socket 2 are provided on one side of the limiting protrusion 11. The battery box 3 is detachably arranged in the limiting protrusion 11. The battery box 3 is provided with a pluggable plug tongue 321 arranged on the socket 12. The battery box 3 is disassembled and installed by the cooperation of the plug tongue 321 and the socket 12. The battery box 3 is also provided with a card female socket 4 cooperating with the card male socket 2. The card male socket 2 is connected to the charging control board, and the card female socket 2 is connected to the charging control board through the card female socket 2. The socket 4 cooperates with the card male socket 2 to realize the circuit connection and disconnection of the battery box 3, and the battery box 3 provides power to the charging control board. When installing the battery box 3, the tongue 321 on the entire battery box 3 (with batteries inside) is inserted obliquely into the socket 12, and then rotated and lowered along the tongue 321. During the installation of the battery box 3, the card male socket 2 and the card female socket 4 are naturally inserted and engaged to complete the electrical connection. With this arrangement, the battery box 3 can be installed without disassembling the base 1.

[0048] The quick-release structure 5 is movably arranged on the base 1 and partially exposed on the outer end surface of the base 1. The quick-release structure 5 can be operated without disassembling the base 1. A guide hole 13 is arranged on the other side of the limiting protrusion 11, and a quick-release slot 322 corresponding to the guide hole 13 is arranged on the other side of the battery box 3. The quick-release structure 5 is pluggable and arranged in the quick-release slot 322. Through the cooperation of the quick-release structure 5, the guide hole 13 and the quick-release slot 322, the battery box 3 is effectively positioned after being installed, thereby preventing the battery box 3 from shaking during use.

[0049] When it is necessary to install the battery box 3, first operate the quick-release structure 5 to disengage the quick-release structure 5 from the quick-release slot 322, then insert the tongue 321 on the battery box 3 (with batteries inside) obliquely into the socket 12, and then rotate and lower it along the tongue 321. During the installation of the battery box 3, the card male seat 2 and the card female seat 4 are naturally inserted and engaged to complete the electrical connection. When the battery box 3 is installed in place, operate the quick-release structure 5 to insert the quick-release structure 5 into the quick-release slot 322, thereby achieving effective installation and fixation of the battery box 3; when it is necessary to remove the battery box 3, first operate the quick-release structure 5 to disengage the quick-release structure 5 from the quick-release slot 322, and then rotate the battery box 3 (with batteries inside) along the tongue 321 to disengage it from the limiting protrusion 11, until the tongue 321 can be taken out of the socket 12. During the removal of the battery box 3, the card male seat 2 and the card female seat 4 are naturally separated.

[0050] The power supply base of the mobile screen set up in the above manner can realize the fast and effective installation of the battery box 3 without disassembling the base 1. Compared with the existing disassembly and assembly methods, it is simple to operate, convenient for users to assemble, and improves the user experience.

[0051] In the above embodiment, the quick release structure 5 includes a quick release slider 51 and a quick release paddle 52. The quick release paddle 52 is movably arranged in a limiting groove on the outer end surface of the base 1. The quick release paddle 52 is connected to the quick release slider 51. The quick release slider 51 is provided with a quick release tongue 511 which is pluggable and arranged in the quick release slot 322.

[0052] It should be noted that by toggling the quick release paddle 52, the quick release slider 51 is driven to move synchronously, so as to realize the engagement and separation of the quick release slider 51 and the battery box 3. When the battery box 3 needs to be fixed, the quick release paddle 52 is toggled to make the quick release slider 51 move synchronously in the direction close to the battery box 3 until the quick release tongue 511 of the quick release slider 51 is inserted into the quick release slot 322. When the battery box 3 needs to be removed, the quick release paddle 52 is toggled to make the quick release slider 51 move synchronously in the direction away from the battery box 3 until the quick release tongue 511 of the quick release slider 51 is separated from the quick release slot 322.

[0053] Please refer to Figure 6 and Figure 7 The quick release paddle 52 includes a quick release lever position 521 and a paddle fixing buckle 522 disposed in the middle of the quick release lever position 521 . The quick release lever position 521 is movably disposed in the limiting groove, and the paddle fixing buckle 522 is clamped and connected with the clamping portion 512 of the quick release slider 51 .

[0054] It is understandable that when in use, the paddle fixing buckle 522 is driven to move synchronously by toggling the quick release handle 521, and the clamping portion 512 of the quick release slider 51 is driven to move synchronously by the paddle fixing buckle 522, thereby driving the quick release slider 51 to move synchronously. The quick release handle 521 is a sheet-like structure, and the moving stroke of the quick release handle 521 is limited by the limiting groove. The limiting groove is provided with a long hole for moving the paddle fixing buckle 522. By providing the long hole, the paddle fixing buckle 522 can be connected to the clamping portion 512 of the quick release slider 51.

[0055] In one embodiment, the quick-release slider 51 is provided with a spring fixing seat 513, and a spring 514 is provided in the spring fixing seat 513. The spring 514 is used to provide a pre-tightening force to move the quick-release slider 51 toward the quick-release slot 322. One end of the spring 514 abuts against the abutting portion in the spring fixing seat 513, and the other end of the spring 514 abuts against the spring seat 515 in the base 1.

[0056] It should be noted that the spring fixing seat 513 is configured as a U-shaped plate to form a U-shaped groove, so that the spring 514 can be compressed and extended under the limitation of the U-shaped groove.

[0057] When the battery box 3 needs to be removed, the quick-release dial position 521 is toggled to make the quick-release slider 51 move synchronously in the direction away from the battery box 3 until the quick-release tongue 511 of the quick-release slider 51 is disengaged from the quick-release slot 322. At the same time, the spring 514 in the quick-release slider 51 is compressed, and the battery box 3 can be removed at this time; when the battery box 3 needs to be fixed, the quick-release dial position 521 is released, and the paddle fixing buckle 522 is driven to move in the direction close to the battery box 3 under the action of the restoring force of the spring 514, and the paddle fixing buckle 522 drives the clamping portion 512 of the quick-release slider 51 to move synchronously, thereby driving the quick-release slider 51 to move synchronously, so that the quick-release tongue 511 of the quick-release slider 51 is inserted into the quick-release slot 322.

[0058] In another embodiment, the quick release slider 51 is provided with a fixing seat 516 , a snap-in protrusion is provided in the fixing seat 516 , a snap-in groove 517 cooperating with the snap-in protrusion is provided in the base 1 , and two snap-in protrusions are provided to limit the travel of the quick release slider 51 .

[0059] It can be understood that when using this type of quick-release slider 51, by toggling the quick-release dial position 521, the quick-release slider 51 is synchronously moved in a direction close to or away from the battery box 3 until the quick-release tongue 511 of the quick-release slider 51 is inserted into or disengaged from the quick-release slot 322, so as to achieve locking and unlocking of the battery box 3. When the quick-release dial position 521 is toggled to the position where the engaging protrusion and the engaging slot 517 are locked, it means that the quick-release tongue 511 of the quick-release slider 51 is fully inserted into the quick-release slot 322, so as to achieve positioning of the battery box 3, or it means that the quick-release tongue 511 of the quick-release slider 51 is fully disengaged from the quick-release slot 322, so as to achieve unlocking of the battery box 3.

[0060] Based on the above embodiment, a first fixed column 518 connected to the quick release slider 51 is provided in the base 1, and the quick release slider 51 is provided with a slide groove 519. The slide groove 519 is connected to the first fixed column 518 through a large cap screw. A second fixed column 6 for connecting the card male seat 2 is also provided in the base 1.

[0061] It should be noted that the quick release tongue 511 at the front end of the quick release slider 51 is inserted into the quick release slot 322, and the first fixing column 518 is inserted into the slide slot 519 of the quick release slider 51, so that the quick release slider 51 can slide on the base 1. The first fixing column 518 is higher than the quick release slider 51. At this time, it is locked to the first fixing column 518 by a large cap screw, which does not affect the sliding of the quick release slider 51 while limiting the freedom of the quick release slider 51 in the height direction. The card male socket 2 is screwed to the second fixing column 6, and the card male socket 2 is connected to the charging control board through electronic wires.

[0062] In the above embodiment, at least two quick-release structures 5 are provided.

[0063] It is understandable that there may be two or more quick-release structures 5, and there is no limitation on this. In the present embodiment, there are two quick-release structures 5, one of which is a quick-release structure 5 provided with a spring 514, and the other is a quick-release structure 5 provided with a snap-on protrusion.

[0064] The processing of the base 1 and the quick-release structure 5 includes: firstly, the card male seat 2 is screwed to the second fixing column 6, and the card male seat 2 is connected to the charging control board through electronic wires; then, the quick-release tongue 511 at the front end of one of the quick-release sliders 51 is inserted into the quick-release slot 322, and the first fixing column 518 is inserted into the slide groove 519 of the quick-release slider 51, so that the quick-release slider 51 can slide on the base 1, and the first fixing column 518 is higher than the quick-release slider 51, and is now screwed to the base 1 by a large cap screw. The first fixing column 518 can limit the freedom of the quick release slider 51 in the height direction without affecting the sliding of the quick release slider 51. The clamping protrusion on the quick release slider 51 and the clamping groove 517 on the base 1 can be locked and unlocked; then one end of the spring 514 is inserted into the spring seat 515, and the other end is inserted into the abutment of the spring fixing seat 513 at the tail of the other quick release slider 51. Since the abutment of the spring seats 515 and the spring fixing seat 513 on both sides are columnar structures, the spring 514 is inserted, and the spring fixing seat 513 is inserted into the spring 514. The seat 513 is formed into a U-shaped groove to protect the spring 514, so the spring 514 can be compressed at this time and ensure that the spring 514 will not collapse. After the compression stroke, the quick release tongue 511 is inserted into the quick release slot 322, and the first fixing column 518 is inserted into the slide groove 519 of the quick release slider 51. Similarly, the first fixing column 518 is higher than the quick release slider 51 and is locked on the first fixing column 518 by a large cap screw, which does not affect the sliding of the quick release slider 51 while limiting the freedom of the quick release slider 51 in the height direction. The slider 51 has no locking point structure, so the quick-release slider 51 can rebound when you release your hand after compression; then turn the back side over, pass the paddle fixing buckle 522 at the lower end of the quick-release lever position 521 through the limiting groove and the long hole of the base 1 and then engage with the engaging portion 512 of the quick-release slider 51, so that the extension and retraction of the quick-release slider 51 can be controlled by turning the quick-release lever position 521; finally, install the remaining base 1 structures that are not related to the removable battery one by one, thereby completing the assembly of the chassis part, and packing it separately from the whole machine and shipping it in an ordinary container.

[0065] As a preferred embodiment, the battery box 3 includes an upper box 31 and a lower box 32. The inner periphery of the upper box 31 is provided with a male buckle, and the outer periphery of the lower box 32 is provided with a female buckle that cooperates with the male buckle.

[0066] It should be noted that the battery box 3 is configured as an upper and lower box 32 structure to facilitate installation and removal of the battery pack 8. The lower box 32 is provided with a battery compartment to facilitate installation of the battery pack 8. An inclined surface is provided on one side of the upper box 31, and the inclined surface is used to contact the quick release tongue 511 of the quick release slider 51, and the head of the quick release tongue 511 is provided with a slope that fits the inclined surface.

[0067] In the above situation, an elastic arm 311 is provided on one side of the upper box 31, and the elastic arm 311 abuts against the inner wall of the limiting protrusion 11, a third fixing column 7 for fixing the card base 4 is provided on one side of the lower box 32, and a quick-release card slot 322 is provided on the other side of the lower box 32.

[0068] It is understandable that the elastic arm 311 is provided on the upper box 31 , and when the battery box 3 is installed, the battery box 3 and the limiting protrusion 11 can be limited and fixed, so as to prevent the battery box 3 from shaking in the limiting protrusion 11 .

[0069] The process of processing the battery box 3 includes: first, locking the card socket 4 on the third fixing column 7 by screws, and then placing the battery pack 8 into the lower box 32 of the battery box 3, connecting the card socket 4 to the port on the card socket 4 through electronic wires, and then buckling the upper box 31 of the battery box 3 on the lower box 32 of the battery box 3, and fixing them by buckling the male buckle on the upper box 31 with the female buckle on the lower box 32, thereby completing the assembly of the battery box 3, which can be shipped separately by a dangerous goods container.

[0070] The battery box 3 adopts a buckle and upper and lower boxes 32 structure, which is convenient for replacing battery packs 8 of different capacities and sizes in the factory. It is designed according to the largest battery pack 8, and the battery packs 8 of other specifications are fastened by replacing different pads. The battery box 3 does not need to be made into styles of different sizes, and the battery compartment of the lower box 32 of the battery box 3 does not need to be made into styles of different sizes. The card mother seat 4 is connected to the wire of the battery pack 8 through the terminal, which can reduce the differentiation of the battery pack 8 and share it with the existing battery pack 8 used for the non-removable battery mobile screen. There is no need for the battery pack 8 factory to customize the card mother seat 4 to be welded on the battery pack 8.

[0071] The process of assembling or disassembling the battery box 3 and the base 1 by the user end includes: first, toggle the quick-release paddle 52 (slider with locking point) to retract the quick-release slider 51. Due to the presence of the snap-in groove 517, the quick-release slider 51 does not rebound, ensuring that there is no contact during the installation of the battery box 3. Then, the plug tongue 321 on the entire battery box 3 (with batteries inside) is obliquely inserted into the socket 12 on the base 1, and then rotated and lowered along the plug tongue 321. At this time, the inclined surface on the battery box 3 contacts the slope of the quick-release tongue 511 on the quick-release slider 51 on the other side. Continuous pressing and lowering causes the quick-release slider 51 to rebound. After being placed in place, the quick-release tongue 511 rebounds into the quick-release slot 322 under the force of the spring 514 to lock the battery box 3. The battery compartment of the battery box 3 is clamped by the elastic arm 311 on the battery box 3 to prevent the battery compartment from shaking. During this process, the card male seat 2 on the base 1 and the card female seat 4 on the battery box 3 are naturally inserted and engaged to complete the electrical connection. Finally, the quick release paddle 52 (a slider with a locking point) is toggled to push the quick release tongue 511 into the quick release slot 322 , thereby achieving double locking of the battery box 3 .

[0072] When disassembling, first push the quick release paddle 52 (slider with locking point) to retract the quick release slider 51. Due to the presence of the snap-in groove 517, the quick release slider 51 does not rebound. Then push the other side of the quick release paddle 52 to push the spring 514 to complete the unlocking, and take out the battery box 3 through the hand-locking position.

[0073] In summary, the power supply base of the mobile screen provided by the present invention designs the power supply base of the mobile screen as a detachable battery structure, and the battery is separated from the whole machine for shipment, thereby reducing freight costs; the quick-release battery box 3 is installed with a fixed structure, which is detachable and convenient for users to assemble, without complicated installation operations, thereby improving user experience; the battery box 3 is in contact with the whole machine through a card-type socket 12, and the user does not need to plug in the wires, thereby improving user experience; the battery pack 8 is connected to the card-type socket 12 board through a seat, and battery packs 8 of different specifications can be replaced without additional customization of the battery, thereby reducing differentiation; the battery box 3 is compatible with a variety of battery packs 8, thereby improving the compatibility of the battery box 3 and reducing the differentiation between the battery compartment and the battery box 3.
