[0045] An embodiment of the DIT film and television vehicle in this utility model:

[0046] In some embodiments, please refer to Figure 1 The DIT video production vehicle includes a vehicle body 11 and wheels 12 mounted on the bottom of the vehicle body 11, making the DIT video production vehicle easy to move. The top of the vehicle body 11 has a work surface for operators to operate equipment. Generally, the work surface at the top of the vehicle body 11 can hold a color mixing table, mouse, keyboard, etc.

[0047] The vehicle body 11 has mounting space 111 and mounting holes 112. In some embodiments, the height of the mounting space 111 may be, but is not limited to, twice the height of the server unit to accommodate several hardware devices within the mounting space 111. The server unit height referred to here is a dimensional unit defined and standardized by the Electronic Industries Alliance (EIA). In this standard, "U" comes from RU, short for Rack Unit, which is the basic unit of height for a rack (or cabinet). Each rack unit (1U) is 1.75 inches high, which is approximately 44.45 millimeters. However, in practical applications, to allow for mechanical tolerances and provide some space between panels, the height per 1U may typically be reduced by approximately 0.03 inches. Multiple mounting holes 112 are arranged vertically to accommodate the mounting of various hardware devices.

[0048] In some embodiments, please refer to Figure 2The vehicle body 11 is a cabinet-shaped structure with side panels, including two vehicle body units arranged vertically. For the sake of distinction, the two vehicle body units are distinguished as first and second. The upper one is the first vehicle body unit 113, and the lower one is the second vehicle body unit 114. The two vehicle body units can be detachably connected together. Furthermore, both vehicle body units have a top plate located at the top. The top plate of the first vehicle body unit 113 is the first top plate 115, and the top plate of the second vehicle body unit 114 is the second top plate 116.

[0049] exist Figure 2 In the first vehicle body unit 113, the first top plate 115 constitutes the work surface of the vehicle body 11. Each vehicle body unit has an installation space 111 and installation holes 112, and the height of the installation space 111 and the number of installation holes 112 of each vehicle body unit are sufficient to accommodate the installation of multiple hardware devices within it.

[0050] Since the two vehicle body units can be detachably connected together, the height of the vehicle body 11 can be changed by removing the first vehicle body unit 113. After the first vehicle body unit 113 is removed, the second top plate 116 of the second vehicle body unit 114 is configured as the work surface of the vehicle body 11.

[0051] Generally, DITs have two working postures: standing and sitting. To accommodate the height of both postures, the height of the first body unit 113 is lower than the height of the second body unit 114. Specifically, the difference between the height of the work surface for the standing posture and the height of the work surface for the sitting posture is equivalent to the height of the first body unit 113; the height of the second body unit 114 is equivalent to the height of the work surface for the sitting posture. Therefore, for DITs working in a standing posture, the first body unit 113 and the second body unit 114 are stacked together, and the first top plate 115 forms the work surface. For DITs working in a sitting posture, the first body unit 113 can be removed, and the second top plate 116 can be configured as the work surface.

[0052] In some embodiments, the height of the first vehicle unit 113 is 6U, and the height of the second vehicle unit 114 is 10U, where U refers to the height of the aforementioned server rack unit. Of course, those skilled in the art will understand that, since it is for personnel use, the heights of the first vehicle unit 113 and the second vehicle unit 114 can be adapted to increase or decrease.

[0053] In some other embodiments, the number of vehicle body units 11 may include three or more vehicle body units.

[0054] Please see Figure 2The side panel of the first body unit 113 is the first side panel 117, and the side panel of the second body unit 114 is the second side panel 118. The inner side of each side panel is a mounting space 111. For the detachable connection method between the first body unit 113 and the second body unit 114, please refer to [link to relevant documentation]. Figure 2 , Figure 3 and Figure 4 From a certain perspective, the first side plate 117 on the left side of the first vehicle body unit 113 has a groove, specifically a first groove 119. The opening of the first groove 119 faces left. On the side of the first groove 119 near the second vehicle body unit 114, there is a vehicle body connection hole on the connecting groove wall 1120. Correspondingly, the top of the second vehicle body unit 114 has a threaded hole. By inserting a threaded fastener 1121 into the vehicle body connection hole and screwing it into the threaded hole, the first vehicle body unit 113 and the second vehicle body unit 114 can be detachably connected.

[0055] Please see Figure 4 In some embodiments, a rivet nut 1134 is fixed to the lower side of the second top plate 116 on the top of the second body unit 114. Specifically, the flange at the top of the second side plate 118 is fitted to the lower side of the second top plate 116, and the rivet nut 1134 is riveted to the flange. The second top plate 116 has clearance holes, allowing a threaded fastener 1121, which passes through the body connection hole on the first body unit 113, to be screwed into the threaded hole of the rivet nut 1134. The threaded fastener 1121 can be a screw or a bolt. By engaging the threaded fastener 1121 with the rivet nut 1134, the first body unit 113 and the second body unit 114 are tightly connected.

[0056] By placing the detachable connection structure between the first vehicle body unit 113 and the second vehicle body unit 114 within the first groove 119, the external structure of the vehicle body 11 becomes simpler, improving the ease of use of the DIT film and television vehicle. Simultaneously, it ensures that operators can easily assemble and disassemble the first vehicle body unit 113 by tightening the threaded fasteners 1121 from the outside, eliminating the need for assemblies within the installation space 111. This ensures convenient assembly and disassembly of the vehicle body 11. Furthermore, the first groove 119, located on the first vehicle body unit 113, can serve as a leverage point for operators to move the first vehicle body unit 113, further enhancing its handling. In other embodiments, the first groove 119 can also be located on the second vehicle body unit 114, with a threaded hole at the bottom of the first vehicle body unit 113.

[0057] In other embodiments, for the detachable connection between the first vehicle body unit 113 and the second vehicle body unit 114, a downwardly extending pin can be provided at the bottom of the first vehicle body unit 113, and a socket can be provided at the top of the second vehicle body unit 114. The first vehicle body unit 113 can be detachably installed on the second vehicle body unit 114 by inserting the pin into the socket. Alternatively, both the first vehicle body unit 113 and the second vehicle body unit 114 can be provided with horizontally extending lugs, with connecting holes provided on the lugs. The detachable connection between the two vehicle body units can be achieved by cooperating with bolt and nut assemblies through the connecting holes.

[0058] Regarding the formation of the first groove 119, in some embodiments, the first side plate 117 has an opening, and the vehicle body 11 also includes a box 1128 and an annular member 1129. The box 1128 has a box opening on one side, and the annular member 1129 is located outside the first side plate 117 and surrounds the opening. The box opening of the box 1128 is aligned with the opening, and the box 1128 and the annular member 1129 are connected by screws. The box 1128 and the annular member 1129 clamp the first side plate 117, thereby forming the first groove 119.

[0059] Thus, the housing 1128 is detachably connected to the first side plate 117. If wear occurs at the point where the housing 1128 mates with the threaded fastener 1121, the detachable connection structure between the first vehicle body unit 113 and the second vehicle body unit 114 can be repaired by replacing the housing 1128. In some other embodiments, for the detachable connection of the housing 1128 to the first side plate 117, holes can be directly drilled around the opening in the first side plate 117, and screws can be inserted into these holes to connect the housing 1128 to the first side plate 117, thus achieving detachable installation of the housing 1128. Alternatively, the first groove 119 can be directly stamped into the first side plate 117.

[0060] Regarding the structure of the vehicle body 11, in some other embodiments, the vehicle body 11 can be a one-piece structure, that is, it is no longer divided into multiple vehicle body units. The vehicle body 11 may also have no side panels, with only the top panel forming the work surface, and the other parts being a frame structure.

[0061] Please see Figure 1 and Figure 5To enhance the storage capacity of the vehicle body 11, a storage panel 13 is also provided on the vehicle body 11. The storage panel 13 is movably installed on the side of the vehicle body 11, specifically at the bottom end of the second vehicle body unit 114. The storage panel 13 has an extended position and a retracted position during its travel. In its extended position, the storage panel 13 lies flat on the outside of the installation space 111, and its position is lower than the work surface, thus forming a support structure capable of supporting items on the outside of the installation space 111. The term "flat" here does not emphasize an absolutely horizontal posture of the storage panel 13, but rather that the storage panel 13 is in a posture that can serve as a support plate on which items can be placed, such as water cups or power supply boxes. Those skilled in the art will understand that due to processing and assembly errors, the storage panel 13 may have a certain degree of tilt, but this must be based on the premise that it can still fulfill its basic function of supporting items. A panel extension retaining structure is provided between the storage panel 13 and the vehicle body 11 to hold the storage panel 13 in its extended position.

[0062] When the shelf 13 is in its retracted position, as Figure 5 As shown, the storage panel 13 stands upright against the side of the vehicle body 11. Here, "against" means close to or near, indicating that the storage panel 13, when folded up from its unfolded state, converges towards the vehicle body 11 to reduce the size of the vehicle body 11 and facilitate its movement. It does not emphasize that the storage panel 13 is in direct contact with the vehicle body 11; that is, when the storage panel 13 is in its folded position, it can be close to the vehicle body 11 or there can be a gap between them. "Upright" does not emphasize absolute verticality relative to the horizontal direction, but rather describes the upright folding of the storage panel 13, achieving a reduction in the horizontal dimension of the vehicle body 11.

[0063] To ensure the storage panel 13 retains its function of holding items even when in the retracted position, in some embodiments, the storage panel 13 has a hook engagement structure that can engage with hooks when in the retracted position. This allows backpacks, handbags, and other items to be hung on the storage panel 13. To ensure stability, when the bottom end of the storage panel 13 is hinged to the vehicle body 11, and the storage panel 13 flips downwards from its retracted position to its unfolded position, a panel retraction retaining structure is provided between the storage panel 13 and the vehicle body 11 to constrain the storage panel 13 to its retracted position. This prevents the storage panel 13 from accidentally unfolding after items are hung on it. When the storage panel 13 is installed on the vehicle body 11 with its top hinged to the vehicle body 11 and flipped upwards from its retracted position to its unfolded position, a panel retraction retaining structure may or may not be provided between the storage panel 13 and the vehicle body 11.

[0064] For specific details regarding the hook-and-loop fit structure, please refer to some embodiments. Figure 6The hook-and-loop mechanism is a hole 131 on the shelf 13. When the shelf 13 is in the retracted position, the side of the shelf 13 facing the mounting space 111 has clearance space, which allows the head of the hook to pass through the hole 131 and be hung on the shelf 13. The hole 131 forms the hook-and-loop mechanism, enabling it not only to engage with a hook but also to bind and secure items to the shelf 13 by engaging with a rope. In other embodiments, the hook-and-loop mechanism can also be a hanging ring on the shelf 13.

[0065] In some embodiments, the shelf 13 can be a perforated board with multiple holes 131 arranged in a rectangular array. The holes 131 have a diameter of 10 mm, and the center-to-center distance between adjacent holes 131 is 16 mm. The shelf 13 may also have insertion holes 137 for straps to pass through. The straps are generally webbing with a larger width and a smaller thickness, so the insertion holes 137 are elongated holes or rectangular holes. In some embodiments, the insertion holes 137 are elongated holes with a length of 3.2 cm. Regarding the arrangement of the insertion holes 137, described with the shelf 13 in the unfolded position, it can have elongated insertion holes 137 that extend horizontally and / or elongated insertion holes 137 that extend front-to-back.

[0066] Regarding the formation of the clearance space, please refer to some embodiments. Figure 1 and Figure 5 The second side plate 118 also has a groove, which is named the second groove 1122. When the shelf 13 is in its retracted position, it is stored in the second groove 1122 and the opening of the second groove 1122 is sealed. The wall surface of the second groove 1122 opposite to its opening is the bottom of the groove. The space between the shelf 13 and the bottom of the second groove 1122 forms a clearance space.

[0067] When the storage plate 13 is in its retracted position, it is stored in the second groove 1122, making the outer structure of the vehicle body 11 simpler and reducing the risk of collision.

[0068] A panel retraction holding structure and an elastic pushing structure are provided between the vehicle body 11 and the storage panel 13. The panel retraction holding structure is used to constrain the storage panel 13 in its retracted position. The elastic pushing structure can pop the storage panel 13 out of the second groove 1122 after the panel retraction holding structure releases the constraint on the storage panel 13.

[0069] In some embodiments, please refer to Figure 6 and Figure 7The retractable retaining structure includes a latch 1123 located on the vehicle body 11 and a lock hole 132 located on the storage plate 13. The latch 1123 is movably mounted on the second side plate 118, which forms the mounting base for the latch 1123. The top groove wall of the second groove 1122 has a hole for the latch 1123 to extend into the second groove 1122. The latch 1123 can be inserted into the lock hole 132 during its active stroke and can also be withdrawn from the lock hole 132.

[0070] The plate retraction and retention structure also includes an elastic element, which is used to push the latch 1123 into the lock hole 132 and maintain its state. The latch 1123 has an operating part 11231 for manual operation, so that the latch 1123 can be manually driven to exit the lock hole 132.

[0071] Please see Figure 7 and Figure 11 The second side plate 118 also has a latch mounting groove 1181 for mounting the latch 1123. The latch 1123 is located in the latch mounting groove 1181 and can move up and down within the latch mounting groove 1181. The elastic element is a spring 1135 disposed between the latch 1123 and the groove wall of the latch mounting groove 1181.

[0072] Specifically, please refer to Figure 7 The second side plate 118 has an opening, and a lock frame 1136 is installed in the opening. For the specific structure of the lock frame 1136, please refer to [link / reference needed]. Figure 8 .

[0073] Please see Figure 9 A back plate 1124 is fixed to the inner side of the second side plate 118, and two stop pins 1125 are fixed on the back plate 1124. A lock frame 1136 is installed between the second side plate 118 and the back plate 1124. The lock frame 1136 has a lock frame flange 11361 located on the side of the second side plate 118 facing away from the back plate 1124. The lock frame 1136 and the back plate 1124 form a bolt mounting groove 1181. The lower end of the bolt mounting groove 1181 has a channel for the bolt 1123 to extend downward.

[0074] Please see Figure 10 The latch 1123 has protruding lugs 11232 on both sides and a spring mounting groove 11233 at the top, which is combined with... Figure 11 The lower end of the spring 1135 is inserted into the spring mounting groove 11233, and the upper end abuts against the upper side wall of the lock frame 1136. Two stop pins 1125 are located below the two lugs 11232, and by engaging with the lugs 11232, they limit the lower limit position of the downward movement of the latch 1123. In some other embodiments, the latch mounting groove 1181 can also be directly stamped into the second side plate 118. The elastic element can also be a rubber block.

[0075] To facilitate the insertion of the shelf 13 into the second groove 1122, a guide ramp 11234 is provided on the latch 1123. When the shelf 13 moves to the retracted position, the shelf 13 can push against the guide ramp 11234 to exert a pushing force on the latch 1123, forcing the latch 1123 to move away from the shelf 13. As the shelf 13 moves to the retracted position, after the lock hole 132 and the latch 1123 are aligned, the latch 1123 is inserted into the lock hole 132 under the pushing force of the elastic element, thus constraining the shelf 13 to its retracted position.

[0076] Please see Figure 7 The elastic push structure is a spring piece 1126 fixed on the second side plate 118. When the shelf 13 is in the retracted position, the spring piece 1126 is compressed and elastically deformed to store energy. When the manual drive lock tongue 1123 is withdrawn from the lock hole 132, the spring piece 1126 can push the shelf 13 out of the second groove 1122.

[0077] In some other embodiments, the elastic pushing structure can also be a torsion spring located at the hinge position between the shelf 13 and the second side plate 118. For the shelf retraction retaining structure, in other embodiments, the shelf 13 can also serve as the mounting base for the latch 1123, i.e., the latch 1123 is mounted on the shelf 13, and the lock hole 132 is located on the second side plate 118. Of course, the shelf retraction retaining structure can also include a stop rod rotatably mounted on the second side plate 118, the axis of rotation of the stop rod extending along the thickness direction of the second side plate 118, and the stop rod having a stop position for stopping the shelf 13 and a clearance position for allowing the shelf 13 to pass during its rotational stroke.

[0078] In some embodiments, please refer to Figure 1 and Figure 5 The bottom end of the shelf 13 is hinged to the second side plate 118. After the shelf 13 pops out from the second groove 1122, it swings downward to the unfolded position. The unfolded holding structure is a pull rod 14 connected between the shelf 13 and the second side plate 118, with one end of the pull rod 14 hinged to the second side plate 118. Please refer to [link / reference]. Figure 6 The shelf 13 has a front flange 133 with an elongated hole 134. The other end of the pull rod 14 is connected to the elongated hole 134 and can slide within it. When the shelf 13 reaches the unfolded position, the end of the pull rod 14 slides to the end of the elongated hole 134 near the second side plate 118. The end of the elongated hole 134 near the second side plate 118 has a slot 1341, and the end of the pull rod 14 is engaged in the slot 1341, so that the shelf 13 is stably held in its unfolded position.

[0079] In some other embodiments, the panel unfolding and retaining structure may also be a cable connected between the shelf 13 and the second side panel 118. The cable is long enough that it is straightened after the shelf 13 reaches its unfolded position. The cable may be a chain, wire rope, etc. The panel unfolding and retaining structure is not limited to the forms listed above, and may also be any other structure capable of holding the shelf 13 in its unfolded position.

[0080] The top of the storage panel 13 is hinged to the vehicle body 11. The storage panel 13 is folded up from its retracted position to its unfolded position. The unfolded panel holding structure is a support structure. Specifically, a support rod can be connected between the storage panel 13 and the second side panel 118. One end of the support rod is hinged to the second side panel 118, and the other end is slidably connected to the elongated hole 134 provided on the storage panel 13. This end has a locking structure to lock the support rod and the storage panel 13. After the storage panel 13 reaches the unfolded position, the support rod and the storage panel 13 are locked by the locking structure so that the storage panel 13 is supported in the unfolded position by the support rod.

[0081] In order to restrain the items on the shelf 13, in some embodiments, please refer to Figure 1 and Figure 2 A lug 1127 is fixed to the bottom of the second groove 1122. Please refer to [link / reference]. Figure 6 The top of the shelf 13 (the end furthest from the vehicle body 11 when in the unfolded position) has a rope connection hole 136, which allows items such as power boxes on the shelf 13 to be held in place by threading a connecting rope through the lug 1127 and / or the rope connection hole 136. In some embodiments, the rope is a strap, the lug 1127 is a U-shaped piece that forms an elongated hole with the bottom of the second groove 1122 to allow a cable tie to pass through, and the rope connection hole 136 is an elongated hole with a size adapted to the strap. The top of the shelf 13 also has a top flange 135, and a locking hole 132 is provided on the top flange 135.

[0082] When the storage panel 13 is in the retracted position, the storage panel 13 covers the two hanging ears 1127 on the bottom of the second groove 1122, thereby protecting the hanging ears 1127 and ensuring that the outer structure of the vehicle body 11 is as simple as possible to reduce the risk of collision.

[0083] In some other embodiments, the second side plate 118 of the vehicle body 11 may not have a second groove 1122. That is, the part of the second side plate 118 forming the side of the vehicle body 11 is a flat structure. When the storage plate 13 is in the retracted position, there is a certain gap between the storage plate 13 and the second side plate 118. The space formed by this gap constitutes the clearance space for the head of the clearance hook, and also avoids interference and collision between the storage plate 13 and the hanging ear 1127. Of course, the hanging ear 1127 can also be set in other positions, and when the storage plate 13 is in the retracted position, the storage plate 13 may not cover the hanging ear 1127.

[0084] Please see Figure 1 and Figure 5 In some embodiments, an extendable table 15 is also provided on the vehicle body 11. The extendable table 15 is movably installed on the side of the vehicle body 11. The extendable table 15 has an unfolded position and a retracted position during its movement. When in the unfolded position, the extendable table 15 is at the same height as the work surface, realizing the extension of the work surface, and office equipment can be placed on the extendable table 15. When in the retracted position, the extendable table 15 stands upright against the side of the vehicle body 11. There is a table unfolding retention structure between the extendable table 15 and the vehicle body 11 to keep the extendable table 15 in its unfolded position. A shelf 13 is located below the extendable table 15, and the bottom end of the shelf 13 is hinged to the vehicle body 11. The shelf 13 is flipped downwards from its retracted position to its unfolded position. This allows the installation position of the shelf 13 to be as low as possible, avoiding the impact of items placed on the shelf 13 on the unfolding and folding storage of the extendable table 15.

[0085] Both the first vehicle body unit 113 and the second vehicle body unit 114 have mounting structures for mounting the extension table 15, so that the extension table 15 can be mounted on the top side of the second vehicle body unit 114 after the first vehicle body unit 113 is removed.

[0086] In some embodiments, one end of the extendable table 15 is hinged to the vehicle body 11, and it can be folded up from its retracted position to its extended position. (See also...) Figure 5 The table unfolding and retaining structure includes a support member 1130 and a locking assembly 1131 connected between the extendable table 15 and the vehicle body 11. One end of the support member 1130 is hinged to the vehicle body 11, and the other end is connected to the extendable table 15 via the locking assembly 1131. The locking assembly 1131 is slidably engaged with the extendable table 15 and has an unlocked state and a locked state. When the locking assembly 1131 is in the locked state, it locks the extendable table 15. When the locking assembly 1131 is in the unlocked state, the extendable table 15 and the locking assembly 1131 can slide relative to each other. In some other embodiments, one end of the support member 1130 may be hinged to the extendable table 15, and the other end may be connected to the vehicle body 11 via the locking assembly 1131.

[0087] Please refer to the details. Figure 12 , Figure 13 and Figure 14 The locking assembly 1131 includes a main body 11311, a slider 11312, and a locking member 11313. The bottom of the extension table 15 has a slide groove 151. The slider 11312 slides in conjunction with the slide groove 151. The slide groove 151 has a structure with a large cavity and a small opening, which can prevent the slider 11312 from coming out of the slide groove 151. In some embodiments, the slide groove 151 adopts a dovetail structure, and the slider 11312 has a dovetail-shaped slider portion that cooperates with the slide groove 151.

[0088] Support member 1130 is hinged to main body 11311, and sliding member 11312 is fixedly installed on main body 11311. Please refer to [link / reference]. Figure 15 The sliding member 11312 has a groove 113121, which is used in conjunction with... Figure 12 and Figure 13 As can be seen, the locking member 11313 is installed in the groove 113121, the sliding member 11312 has a first clamping part 113122, and the locking member 11313 has a second clamping part 113131. The locking assembly 1131 and the extension table 15 can be relatively locked by the first clamping part 113122 and the second clamping part 113131 being relatively close to the edge 152 of the clamping groove 151.

[0089] Please see Figure 16 The main body 11311 has a main body groove 113111, see also Figure 12 and Figure 13 To drive the second clamping part 113131 towards the first clamping part 113122, a driving threaded component 11314 is provided. The head of the driving threaded component 11314 is disposed within the main body groove 113111. After the sliding member 11312 is fixed on the main body 11311, the head of the driving threaded component 11314 is constrained in the vertical direction between the sliding member 11312 and the main body 11311. Please refer to [link / reference]. Figure 15 The bottom of the groove 113121 of the sliding member 11312 has a through hole 113123 extending in the vertical direction. The rod of the driving threaded member 11314 extends through the through hole 113123 into the groove 113121 and engages with the locking member 11313. The locking member 11313 cannot rotate in the groove 113121, but can slide up and down. The locking member 11313 and the driving threaded member 11314 form a nut screw mechanism. Thus, by rotating the driving threaded member 11314, the locking member 11313 can be driven to move toward and away from the first clamping part 113122, thereby achieving clamping and releasing of the opening edge 152.

[0090] In order to drive the threaded part 11314 to rotate, the locking assembly 1131 also includes a drive wrench 11315. The head of the drive wrench 11315 is sleeved around the head of the threaded part 11314 and engages with the head of the threaded part 11314 to prevent rotation. Thus, the drive wrench 11315 can drive the threaded part 11314 to rotate forward and backward.

[0091] In some other embodiments, the table unfolding and retaining structure may also be a ratchet and pawl structure with an unlocking function disposed between the extendable table 15 and the vehicle body 11. Alternatively, the table unfolding and retaining structure may be a support rod disposed between the extendable table 15 and the vehicle body 11, with one end of the support rod hinged to the vehicle body 11, and a slot provided at the bottom of the extendable table 15. The position of the slot and the length of the support rod satisfy the following condition: after the extendable table 15 reaches its unfolded position, the other end of the support rod can be inserted into the slot at the bottom of the extendable table 15.

[0092] Please see Figure 17 Regarding the mounting holes 112 on the vehicle body 11, a mounting strip 1132 is fixedly installed on the vehicle body 11, and multiple mounting holes 112 are arranged vertically on the mounting strip 1132. For more reliable hardware mounting, please refer to [link / reference needed]. Figure 17 The mounting strip 1132 is a bent plate structure, having a first support plate portion 11321 and a second support plate portion 11322 with their plate surfaces perpendicular to each other. Both support plate portions have mounting holes 112. The mounting holes 112 on the first support plate portion 11321 are through in the front-back direction, which is defined as the first direction, and the mounting holes 112 in this direction are the first mounting holes. The mounting holes 112 on the second support plate portion 11322 are through in the left-right direction, which is defined as the second direction, and the mounting holes 112 in this direction are the second mounting holes.

[0093] Between the two support plate parts is a transition connecting plate part 11323, which is provided with a fixing hole 11324 for fixing the mounting strip 1132 to the vehicle body 11.

[0094] Based on the rectangular structure of the vehicle body 11, an installation strip 1132 is fixedly installed at each of the four corners of the vehicle body 11. That is, on a single side, two installation strips 1132 are installed at the front and back. In this way, when installing hardware equipment, multiple fixed installation points can be achieved at both the front and back ends of the hardware equipment.

[0095] The first mounting strip is located at the front right, the second mounting strip at the front left, the third mounting strip at the rear right, and the fourth mounting strip at the rear left. The two first support plate portions 11321 of the first and second mounting strips are located on opposite sides of their second support plate portions 11322. The two second support plate portions 11322 of the first and third mounting strips are located on opposite sides of their first support plate portions 11321. The two first support plate portions 11321 of the third and fourth mounting strips are located on opposite sides of their second support plate portions 11322. This allows for the selection of first mounting holes and / or second mounting holes on different mounting strips 1132 to form a mounting hole group for mounting the hardware device, depending on the structure of the hardware device to be installed.

[0096] For example, the first mounting holes on the first and second mounting strips can form a mounting hole group, connecting to the left and right ends of the hardware device; or the first mounting holes on the first mounting strip and the second mounting holes on the third mounting strip can form a mounting hole group, connecting to the front and rear ends of the hardware device; or the second mounting holes on the four mounting strips 1132 can connect to the four corners of the hardware device. Of course, the combination of mounting hole groups is not limited to those listed here. Depending on the structure of the hardware device to be installed, different mounting holes 112 on the mounting strips 1132 can be selected to form mounting hole groups.

[0097] For example, for relatively lightweight hardware devices to be installed, both sides of the device can be fixedly connected to the corresponding first mounting holes, typically secured with screws. For relatively heavy hardware devices, one end can be connected to the first mounting holes on the mounting strips 1132 on both sides of the front end of the mounting space 111, secured with screws, while the other end extends to the rear end of the mounting space 111 and connects to the second mounting holes on both sides of the rear end. It can be secured in the corresponding second mounting holes using retaining protrusions to complete the installation. In other embodiments, the number of mounting strips 1132 can be one, two, three, etc.

[0098] The hardware device can be installed on the vehicle body 11 via the mounting holes 112, either directly or indirectly. Direct installation involves aligning the mounting structure on the hardware device with the mounting holes 112 on the vehicle body 11 and securing the hardware device with bolts and nuts. For indirect installation, please refer to [reference needed]. Figure 1 and Figure 2 The mounting plate 1133 is fixedly installed in the mounting space 111 through the mounting hole 112, and then the corresponding hardware device is fixed on the mounting plate 1133. The mounting plate 1133 constitutes part of the hardware device.

[0099] Please see Figure 5The vehicle body 11 also includes a column 16 located at the rear of the vehicle body 11, with a handle 17 installed on the column 16 to facilitate moving the cabinet. An extension truss 18 is also installed on the column 16, on which photographic accessories can be mounted. A monitor 19 is also mounted on the column 16 via a bracket.

[0100] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
