[0022] A director's cart is a multi-functional trolley used on filming locations. It can hold various filming equipment, serve as a base for mounting camera equipment for mobile shooting, and also function as a workbench.

[0023] In order to reduce the overall height and prevent the director's vehicle from sliding relative to the transport vehicle during transportation, the wheels are usually removed and placed inside the vehicle body. However, since the wheels are difficult to fix inside the vehicle body, they may move and collide due to bumps during transportation, causing damage to the equipment.

[0024] This utility model proposes a wheel restraint device 100, referring to... Figures 1 to 2 The wheel restraint 100 is used to connect the wheel 300. The wheel 300 is provided with a quick-release structure 310. The wheel restraint 100 includes a base plate 110, which is arranged in a strip shape. The base plate 110 is provided with a first connecting part 111 for connecting with the vehicle body 200. At least one end of the base plate 110 protrudes from the surface and is provided with a connecting seat 112. The free end of the connecting seat 112 is provided with a second connecting part 1121 for detachably connecting with the quick-release structure 310.

[0025] In this embodiment, the base plate 110 serves as the main body of the wheel restraint device 100, acting as a connecting link between the wheel 300 and the vehicle body 200. The base plate 110 is strip-shaped, with its length typically several times its width. This slender geometry allows it to evenly distribute the load of the wheel 300 on the base plate 110, thus preventing the base plate 110 from detaching from the vehicle body 200. The base plate 110 has a first connecting portion 111 that connects to the vehicle body 200. The first connecting portion 111 can be a plug-in connector that plugs into the vehicle body 200, or a connecting lug 113 through which a threaded connector passes and is threadedly connected to the vehicle body 200. To ensure its strength, the base is entirely made of metal, such as aluminum alloy or stainless steel. The connecting seat 112 is a connecting structure disposed at at least one end of the base plate 110. Specifically, it can be a block-shaped solid structure or a plate-shaped hollow structure. The connection method between the connecting seat 112 and the base plate 110 can be welding or integral molding, without further limitation. The free end of the connecting seat 112, that is, the end of the connecting seat 112 away from the base plate 110, is provided with a second connecting part 1121. The second connecting part 1121 is used for detachable connection with the quick-release structure 310 of the wheel 300. The second connecting part 1121 is also made of metal, such as aluminum alloy or stainless steel. The second connecting part 1121 can be integrally molded with the connecting seat 112 through sheet metal processing, or it can be welded to the opposite sides of the connecting seat 112. It can be understood that the wheel restraint 100 can be an independent part, connected to the vehicle body 200 by welding or by screws; or it can be a structure integrally molded with the vehicle body 200.

[0026] The second connecting part 1121 cooperates with the quick-release structure 310 of the wheel 300. It can be a combination of threaded parts and threaded holes, a combination of snap-fit ​​parts and snap-fit ​​openings, or a combination of plug-in parts and plug-in openings. As long as the combination structure can realize the quick installation and connection of the second connecting part 1121 and the wheel 300, no further limitation is made here.

[0027] Handcarts, such as director's carts 1000, have wheels 300 attached to the bottom of the cart body 200 when in use, allowing the cart to be pushed for easy transport and enabling mobile shooting. When the handcart is in storage, the wheels 300 are detached from the bottom of the cart body 200. The wheel restraint 100 is installed inside the basket of the cart body 200 via the first connecting part 111. The detached wheels 300 are detachably connected to the second connecting part 1121 of the wheel restraint 100, fixing the wheels 300 to the basket and preventing them from swinging around inside the basket during transport or handling, thus avoiding collisions or damage to other equipment inside the basket.

[0028] This utility model's technical solution uses a wheel restraint device 100 to fix the wheel 300. The wheel restraint device 100 includes a base and two second connecting parts 1121. One side of the base has a first connecting part 111 for connecting with the vehicle body 200, and the other side of the base has a second connecting part 1121 for detachable connection with the quick-release structure 310 of the wheel 300. The wheel 300 is connected to the wheel restraint device 100 through the second connecting parts 1121, thereby connecting the wheel 300 to the vehicle body 200. The beneficial effect of this utility model is that by fixing the wheel 300 with the wheel restraint device 100, the wheel 300 is prevented from swinging around inside the vehicle body 200, colliding with or damaging other equipment inside the vehicle body 200.

[0029] In some embodiments, refer to Figure 1 and Figure 2 Both ends of the base plate 110 are provided with connecting seats 112.

[0030] In this embodiment, there are two connecting seats 112, which are respectively disposed at both ends of the base plate 110. Each connecting seat 112 has a second connecting part 1121 at its free end, and the two connecting seats 112 protrude in the same direction. The two connecting seats 112 are connected to the vehicle body 200 through the connection of the base plate 110, and are detachably connected to the quick-release structure 310 of the wheel 300 through the second connecting part 1121. Each end of the wheel restraint 100 can be connected to and accommodate one wheel 300. Common four-wheeled trolleys only need two wheel restraints 100 to accommodate all the wheels 300, which is convenient for installation and saves costs. The two connecting seats 112 have the same shape and the second connecting part 1121 on them also has the same structure. When the wheel 300 is installed on the second connecting part 1121, it is not necessary to distinguish which wheel 300 is connected to which second connecting part 1121, thus improving the efficiency of connection. The two connecting seats 112 can be symmetrically arranged at opposite ends of the base plate 110 with the central axis of the base plate 110 as the axis of symmetry, or they can be formed by translating the same shape. No further limitation is made here.

[0031] In some embodiments, refer to Figure 1 and Figure 2 The connecting seat 112 includes two side plates 1122 protruding from the surface and arranged opposite each other, and the second connecting part 1121 includes outwardly turned protrusions located on both sides of the free end of the side plates 1122.

[0032] In this embodiment, in order to reduce the overall material consumption of the wheel restraint device 100 and reduce production costs, the connecting seat 112 is two side plates 1122 located on opposite sides of the protruding surface of the base plate 110. The side plates 1122 are made of metal, such as aluminum alloy or stainless steel. The connection between the two side plates 1122 and the base plate 110 can be a welding connection, or the base plate 110 and the two side plates 1122 can be integrally formed by bending the two sides of the base plate 110. The two sides of the free end of the side plate 1122 form outward protrusions as the second connecting parts 1121. The outward protrusions on both sides are used to snap into the quick-release structure 310 of the wheel 300. The quick-release structure 310 of the wheel 300 is a quick-release interface. The quick-release interface of the wheel 300 can be snapped into the second connecting parts 1121 on both sides, i.e. the outward protrusions on both sides, through its own elastic deformation or movable structure, so as to fix the wheel 300 on the wheel restraint 100 and prevent the wheel 300 from shaking inside the vehicle body 200 when the vehicle is being transported or moved.

[0033] In some embodiments, refer to Figure 2 The connector 112 is set at an angle.

[0034] In this embodiment, the connecting seat 112 is inclined relative to the plane of the base plate 110, that is, the straight line of the opposite sides of the connecting seat 112 forms an angle with the perpendicular bisector of the base plate 110, and the angle is an acute angle. The inclined connecting seat 112 can save space in the length direction of the base plate 110, and more connecting seats 112 can be set in a limited space, thus achieving the effect of saving space.

[0035] In some embodiments, refer to Figure 2 The end face of the free end of the side plate 1122 is inclined relative to the surface plane.

[0036] In this embodiment, the end face of the free end of the side plate 1122 is inclined relative to the surface of the base plate 110. That is, the extended surface of the side plate 1122 away from the base plate 110 forms an angle with the plane of the base plate 110, specifically an acute angle. The inclined end face of the free end of the side plate 1122 saves space in the vertical direction, preventing the wheel restraint device 100 and the wheel 300 from occupying a large portion of the space inside the vehicle body 200, so that more photographic equipment can be accommodated inside the vehicle body 200.

[0037] In some embodiments, refer to Figure 1 A connecting beam 1123 is also provided between the two side plates 1122.

[0038] In this embodiment, a connecting beam 1123 is also provided between the two side plates 1122. The connecting beam 1123 is made of metal, such as aluminum alloy or stainless steel. The two ends of the connecting beam 1123 are respectively connected to the edges of the two side plates 1122. The specific connection method can be welding or plug-in connection, etc., which is not further limited here. The connecting beam 1123 specifically includes a first connecting beam 1123 and a second connecting beam 1123. The first connecting beam 1123 is located between two outward protrusions on the same side of the two side plates 1122, which can improve the strength of the two outward protrusions, thereby improving the strength of the second connecting part 1121, and finally improving the connection strength between the wheel restraint 100 and the quick-release structure 310 of the wheel 300, preventing the wheel 300 from falling off the wheel restraint 100 during transportation or handling, causing collision or damage to the equipment. The second connecting beam 1123 is positioned between the two side plates 1122 facing away from the bottom plate 110 to enhance the strength of the connecting seat 112 itself. Each side of the second connecting beam 1123 is connected to one side plate 1122. The connection method can be welding or plugging, and is not further limited here. The second connecting beam 1123 enhances the connection strength between the two side plates 1122, preventing deformation under pressure. Deformation would lead to an unstable connection between the quick-release structure 310 of the wheel 300 and the connecting seat 112, causing the wheel 300 to detach from the wheel restraint 100 during transportation or handling, resulting in collision or damage to the equipment.

[0039] To further enhance the strength of the base itself, in a preferred embodiment, two second connecting beams 1123 are spaced apart along the extension direction of the side plate 1122 away from the edge of the base plate 110, thereby preventing the two side plates 1122 from deforming under pressure and preventing the connection between the connecting seat 112 and the wheel 300 from failing. In another preferred embodiment, since the second connecting part 1121, i.e., the outwardly protruding part, is subjected to a large force when connected to the wheel 300, the two second connecting beams 1123 are respectively located near the two ends of the side plate 1122, which can enhance the overall strength of the second connecting part 1121, thereby preventing the connection between the second connecting part 1121 and the wheel 300 from failing.

[0040] In some embodiments, refer to Figure 1 and Figure 2 The base plate 110 has lugs 113 extending outward from both sides of its edge, and the first connecting part 111 is a screw through hole provided in the lug 113.

[0041] In this embodiment, the lug 113 is a connecting structure extending outward from one side edge of the base plate 110. The lug 113 allows the connection point to extend from the base plate 110, providing sufficient operating space for the installation, tightening, and disassembly of fasteners (such as bolts and nuts). The first connecting portion 111 is a screw through-hole formed on the lug 113. Threaded fasteners (such as bolts or nuts) pass through the first connecting portion 111 on the lug 113 and connect to the threaded connection hole on the vehicle body 200 to fix the wheel restraint 100 to the vehicle body 200. The lug 113 can be a separate part, welded to opposite sides of the base plate 110, or it can be an integral structure formed with the base plate 110 and / or the side plate 1122, formed by milling or other methods; no further limitations are made here.

[0042] In some embodiments, the lug 113 is formed by stamping a side plate 1122.

[0043] In this embodiment, the base plate 110, side plate 1122, and lug 113 are integrally formed from a single sheet metal. This integral forming provides higher connection strength between the base plate 110, side plate 1122, and lug 113, resulting in a more stable overall structure of the wheel restraint 100 and improved connection stability between the wheel restraint 100 and the wheel 300. Specifically, the processing method can be as follows: first, mill two lugs 113 on opposite sides of the two base plates 110, extending along the plane of the base plate 110; then, bend the opposite sides of the base plate 110 in the same direction to form the side plates 1122, thus completing the wheel restraint 100. Alternatively, the opposite sides of the base plate 110 can be bent in the same direction to form the side plates 1122, then two lugs 113 can be punched on the side plates 1122, and finally, the lugs 113 can be bent to be flush with the base plate 110, completing the processing of the wheel restraint 100.

[0044] This utility model further proposes a director vehicle 1000, as shown in the reference... Figures 3 to 5 It includes a vehicle body 200, multiple wheels 300 and multiple wheel restraints 100, the multiple wheels 300 being detachably connected to the vehicle body 200; the wheel restraints 100 are the wheel restraints 100 as described above.

[0045] In this embodiment, the vehicle body 200 is the main structure of the director's vehicle 1000, serving to house photographic equipment and connect shooting devices. The vehicle body 200 can be made of a sturdy and durable metal material, such as aluminum alloy or titanium alloy. The specific shape and structure of the vehicle body 200 should be determined according to actual needs. A wheel restraint 100 is provided on the vehicle body 200. The wheel restraint 100 can be integrally formed with the vehicle body 200 or can be a separate component, connected to the vehicle body 200 by screws or welding. Multiple wheels 300 are detachably installed on the bottom surface of the vehicle body 200, allowing the director's vehicle 1000 to be pushed, saving effort and enabling mobile shooting. The wheels 300 are detachably connected to the bottom surface of the vehicle body 200 via a quick-release structure 310, such as by snap-fit ​​or plug-in connection. Multiple wheel restraints 100 can be set independently of each other. The second connecting part 1121 on the connecting seat 112 of each wheel restraint 100 can be detachably connected to the quick-release structure 310 on the wheel 300. Each wheel restraint 100 can be installed in different positions on the vehicle body 200, making the installation method more flexible.

[0046] In some embodiments, refer to Figure 4 and Figure 5 The wheel 300 also includes a quick-release structure 310, which includes a fixing part 311 and a movable part 312 movably connected to the fixing part 311. The fixing part 311 and the movable part 312 can be snapped into the second connecting part 1121.

[0047] In this embodiment, a quick-release structure 310 is provided on the wheel 300 for detachable connection with the wheel restraint 100 and the vehicle body 200 of the director vehicle 1000, thereby improving the speed of disassembling and installing the wheel 300 and enhancing the ease of use of the director vehicle 1000. The quick-release structure 310 includes a fixing part 311 and a movable part 312 movably connected to the fixing part 311. The movable part 312 has an unlocked state away from the fixing part 311 and a clamping state close to the fixing part 311. When the movable part 312 is in the clamping state, the movable part 312 and the fixing part 311 are engaged with the second connecting part 1121 of the wheel restraint 100 or the connecting interface on the vehicle body 200 to connect the wheel 300 to the wheel restraint 100, thereby fixing the wheel 300. When the movable part 312 is switched to the unlocked state, it can be detached from the second connecting part 1121 of the wheel restraint 100 or the vehicle body 200, thus removing the wheel.

[0048] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model.
