The first screw connects and fixes the adjustable frame 11 and the corner piece 12.

[0043] Please refer to Figure 2and Figure 7 , Figure 2 The frame shown is in its smallest, shrunk state. Figure 7 The frame 1 shown is in its maximum extended state. Frame 1 has four adjustment points (first adjustment structure 13), distributed clockwise or counterclockwise. When adjustment is needed, the first screw is loosened, and the relative position between the adjusting frame 11 and the corner piece 12 is moved to adjust the length and width of frame 1; after adjustment to the appropriate position, the first screw is tightened to lock it in place. During adjustment, the length or width of frame 1 can also be adjusted individually.

[0044] In other embodiments, the two adjustment points in the length direction of the frame 1 can also be symmetrically arranged along the length center axis, and the two adjustment points in the width direction of the frame 1 can also be symmetrically arranged along the width center axis; or, adjustment points are provided at both ends of the adjustment frame 1, and a total of 8 adjustment points are provided on the frame 1, which can also realize the adjustment of the length and width directions of the frame 1.

[0045] In other embodiments, the frame 1 includes four L-shaped structures, each L-shaped structure being integrally formed and connected to the aforementioned adjustable frame 11 and corner piece 12, which can also realize the adjustment of the length and width of the frame 1.

[0046] In other embodiments, other adjustment structures can also be provided at the adjustment point to achieve adjustment and fixed connection. For example, the adjustment frame 11 and the corner piece 12 can be connected by a screw and a nut, or the adjustment frame 11 and the corner piece 12 can be provided with a buckle and a slot, wherein the slot has multiple positions, and the buckle can be engaged in different positions, so as to achieve adjustment of specific length and width, and also meet certain usage requirements.

[0047] Please refer to Figure 9 In this embodiment, a limiting part 121 is provided on the corner piece 12. The limiting part 121 is located at the front corner of the corner piece 12, and the limiting part 121 has an edge-wrapping structure and extends inward. Preferably, the limiting part 121 and the corner piece 12 are an integral structure. The charging module 2 is installed on the back of the frame 1, and the charging module 2 and the limiting part 121 limit and fix the tablet computer 7 from both the front and rear sides.

[0048] In other embodiments, the limiting part 121 may also be provided on the adjusting frame 11, or simultaneously provided on the adjusting frame 11 and the corner piece 12, which can also serve as a limiting part.

[0049] In other embodiments, the limiting part 121 can be other structures, such as sheet-like structures with letters, numbers, or patterns, which can also serve as a limiting function and enhance the aesthetics.

[0050] Please refer to Figure 1 and Figure 8 In this embodiment, the charging module 2 includes a mounting base 21 and a charging conversion component 22. The mounting base 21 is a long strip structure that spans across the middle rear of the frame 1 along its width direction. The mounting base 21 and the limiting part 121 together limit the tablet computer 7. The mounting base 21 is adjustable and can be scaled along the width direction of the frame 1 to accommodate the scaling adjustment of the frame 1 in the width direction.

[0051] Mounting base 21 includes a first mounting base 211 and a second mounting base 212. A second adjustment structure 213 is provided between the first mounting base 211 and the second mounting base 212. The second adjustment structure 213 includes a second slot, a second threaded hole, and a second screw. The first mounting base 211 and the second mounting base 212 have complementary recessed platforms that are connected to the adjustment frame 11 and the corner piece 12. The recessed platform of the first mounting base 211 has a second slot, which is arranged along the width direction of the frame 1. The recessed platform of the second mounting base 212 has a second threaded hole, which is aligned with the second slot. A second screw is connected between the second threaded hole and the second slot, passing through the second slot from back to front and connecting to the second threaded hole. Similarly, the length direction (width direction of the frame 1) of the mounting base 21 can be adjusted by loosening and tightening the second screw.

[0052] The end of the first mounting base 211 furthest from the second mounting base 212 is connected to a long-side adjustable frame 11 on the frame 1, and the end of the second mounting base 212 furthest from the first mounting base 211 is connected to another long-side adjustable frame 11 on the frame 1. The second mounting base 212 and the adjustable frame 11 are fixedly connected, while the first mounting base 211 and the adjustable frame 11 are adjustable. Since the adjustment points of the two adjustable frames 11 in the length direction are located at the left and right ends respectively, the connection between the first mounting base 211 and the adjustable frame 11 needs to be set to be movable and adjustable along the length direction of the frame 1 so that the mounting base 21 can maintain its position during the scaling of the frame 1. Of course, setting the second mounting base 212 and the adjustable frame 11 to be adjustable can also achieve coordinated adjustment with the scaling of the frame 1. A third adjustment structure 214 is provided between the first mounting base 211 and the adjustable frame 11. The third adjustment structure 214 also includes a strip-shaped slot, screw hole, and screw, and its structure and function are the same as the first adjustment structure 13 and the second adjustment structure 213.

[0053] In other embodiments, if the adjustment points of the two long sides of the frame 1 are located at the same end, that is, symmetrically arranged along the length direction, there is no need to set an adjustable connection between the first mounting base 211 and the adjustment frame 11; a fixed connection is sufficient.

[0054] In this embodiment, the first mounting base 211 is relatively small and only serves to adjust the connection. The second mounting base 212 is relatively larger and also serves to mount the charging conversion assembly 22.

[0055] The charging conversion component 22 includes a circuit board 221, an input terminal 222, and an output terminal 223. A mounting cavity is provided on the second mounting base 212, and the circuit board 221 is concealed within this cavity. An opening is provided on the side of the mounting cavity, and the input terminal 222 and output terminal 223 are respectively installed at this opening. The input terminal 222 and output terminal 223 are electrically connected to the circuit board 221 and are exposed on the outside through the opening. The circuit board 221 has a charging conversion circuit capable of converting the voltage of the battery used in the video device to the voltage used by the tablet computer 7. The input terminal 222 includes a positive connection terminal and a negative connection terminal. The input terminal 222 serves as the input end of the charging conversion component 22, used for electrical connection with the battery used in the video device to obtain the electrical energy output by the battery. The output terminal 223 has interfaces such as TYPE-A and TYPE-C. The output terminal 223 serves as the output end of the charging conversion component 22, used for electrical connection with the tablet computer 7 via a data cable to transmit the converted electrical energy to the tablet computer 7. One or more output terminals 223 can be set. If multiple terminals are set, they can also charge other electronic devices at the same time.

[0056] In other embodiments, the output terminal 223 can also be a raised connection terminal disposed inside the frame 1. The raised connection terminal is connected to the circuit board 221 via a cable. The raised connection terminal can be directly inserted into the charging port of the tablet computer 7 to form an electrical connection. This structural solution can also realize the power supply to the tablet computer 7.

[0057] In this embodiment, the second mounting base 212 is provided with a mounting part 2121, which is located on the back of the second mounting base 212. The mounting part 2121 is a snap-fit ​​structure adapted to the battery of the video equipment. For example, the mounting part 2121 consists of two limiting strips with an inverted L-shaped cross-section, forming a centrally open slot. This mounting part 2121 can be used to insert an NP-F550 series battery 4, which is a conventional battery for video equipment. The input terminal 222 is located at the bottom of the slot and is used for electrical connection with the inserted video equipment battery.

[0058] Please refer to Figure 10 In other embodiments, the mounting part 2121 is configured as two symmetrically arranged right-angled triangular clips, with the hypotenuses of the two triangles facing each other to form a V-shaped latching part. This mounting part 2121 is used to insert a V-port battery 5, which is a conventional type of battery used in film and television equipment.

[0059] Please refer to Figure 11 In other embodiments, the second mounting base 212 is configured to be adapted to the Andon battery, and the mounting part 2121 is a gourd-shaped slot. The mounting part 2121 is used to snap the Andon battery 6, which is also a conventional battery for film and television equipment.

[0060] In other embodiments, the second mounting base 212 and the mounting part 2121 are configured with other structures for mounting batteries for other models and types of film and television equipment such as NP-FW50, NP-FZ100, and LP-E6.

[0061] In this embodiment, the second mounting base 212 is a detachable structure, and the second mounting base 212 that is compatible with different batteries for film and television equipment can be selected and installed, so that the protective frame can be adapted to different batteries for film and television equipment.

[0062] Please refer to Figure 5 and Figure 6 In this embodiment, the frame 1 is provided with several connecting parts 14, such as mounting holes that can be connected to film and television equipment or commonly used components of film and television equipment. These mounting holes are located in the middle of the top and bottom of the frame 1 (the middle of the two long sides). The connecting parts 14 allow the protective frame to be installed and fixed onto film and television equipment.

[0063] Please refer to Figure 3 and Figure 4 In this embodiment, the frame 1 is also provided with a clearance opening 15. There are multiple clearance openings 15. The clearance openings 15 are mainly used to avoid the power button, volume button, charging port, speaker and other functional components of the tablet computer 7, so as to prevent the frame 1 from blocking the functional components of the tablet computer 7.

[0064] Please refer to Figure 8 and Figure 9 In this embodiment, one or more flexible gaskets 3 are respectively provided on the inner sides of the frame 1 and the mounting base 21. The flexible gaskets 3 are made of flexible plastic or other materials. The flexible gaskets 3 are used to place the tablet computer 7 between the tablet computer 7 and the frame 1 and the mounting base 21 to avoid rigid contact between the frame 1 and the mounting base 21 and the tablet computer 7, and to avoid scratches or abrasions to the tablet computer 7. The number and size of the flexible gaskets 3 can be set according to the actual use needs. The flexible gaskets 3 can be fixed to the frame 1 and the mounting base 21 by means of adhesive bonding, heat sealing, etc.

[0065] The tablet computer protective frame provided in this embodiment can protect the tablet computer 7 and improve its drop resistance. Since the frame is equipped with a charging module 2, the charging conversion component 22 on the charging module 2 can convert the voltage input by the battery of the film and television equipment into the voltage adapted to the tablet computer 7, so that film and television workers can directly install the battery of the film and television equipment onto the protective frame to charge the tablet computer 7. In addition, the mounting part 2121 on the mounting base 21 can detachably install the battery of the film and television equipment, and the tablet computer 7 can be kept working for a long time by replacing the battery.
