Description

Technical Field

[0001] The present invention relates to the technical field of camera cars, and particularly to a track camera car and an adjustment system. Background Art

[0002] In the field of film and television shooting, track camera cars play an indispensable role in obtaining high-quality and diverse shooting pictures. It can provide a stable and smooth mobile shooting platform for cameras, helping directors to create rich and unique visual effect shots, greatly enhancing the artistic expressiveness and visual impact of film and television works.

[0003] Among them, the track camera car includes:

[0004] Tracks, which are arranged on the ground and at least two are provided along its own width direction;

[0005] A camera car, with at least two spaced rollers provided below it, at least one roller is provided on each track, and the rollers are in rolling connection with the tracks.

[0006] By the camera car running on the tracks, multi-angle and stable picture shooting can be achieved. According to different scene requirements, the tracks are divided into narrow gauge tracks and wide gauge tracks. Among them, the gauge is the distance between two tracks. Specifically, narrow gauge tracks are suitable for small indoor shooting scenes so that the camera car can flexibly shuttle in limited spaces. Wide gauge tracks are suitable for large outdoor shooting scenes, especially for shooting grand scenes, and can meet the shooting requirements of long distances and large amplitudes.

[0007] However, the existing track camera cars are only applicable to tracks of one gauge and cannot be applicable to tracks of various gauges. Therefore, for tracks of different gauges, camera cars adapted to their gauges need to be made, that is, the distance between adjacent rollers in each camera car corresponds to each gauge one by one. Making multiple camera cars not only increases the shooting cost, but also requires carrying multiple camera cars for shooting, increasing the difficulty of shooting. Summary of the Invention

[0008] In view of this, the present invention provides a track camera car and an adjustment system to solve the problem that the existing track camera cars cannot be applicable to tracks of various gauges, and for tracks of different gauges, camera cars adapted to their intervals need to be made, that is, multiple camera cars need to be made, which not only increases the shooting cost, but also requires carrying multiple camera cars for shooting, increasing the difficulty of shooting.

[0009] In a first aspect, the present invention provides a track camera car for use in cooperation with tracks. The tracks are provided with at least two along their own width direction. The track camera car includes:

[0010] A base;

[0011] Moving units are provided on the base, and at least two moving units are provided at intervals. At least one moving unit is provided on each of the tracks, and the moving units are in rolling connection with the tracks.

[0012] An adjustment unit is provided between the base and the moving units, and is at least used to adjust the distance between adjacent moving units along a first direction according to the gauge of the track.

[0013] Advantageous effects: By providing the adjustment unit, the adjustment unit can adjust the distance between adjacent moving units along the first direction, so that the moving units can be applicable to tracks with various gauges. When the gauge of the track changes, the adjustment unit adjusts the distance between adjacent moving units along the first direction to adapt to the gauge. There is no need to manufacture track camera cars adapted to various gauges in the related art, thereby improving the adaptability of the track camera car to different gauges, reducing the number of manufactured track camera cars, and further achieving the technical effect of saving shooting costs. At the same time, during the shooting process, only one track camera car needs to be carried to adapt to tracks with multiple gauges, reducing the number of track camera cars required to be carried during the shooting process, so as to achieve the technical effect of reducing the shooting difficulty.

[0014] In an optional implementation manner, the adjustment unit includes:

[0015] A first adjustment structure is provided on the base. The first adjustment structure is connected to each of the moving units and is used to adjust the distance between adjacent moving units along the first direction.

[0016] Advantageous effects: By providing the first adjustment structure, the user can drive the first adjustment structure to adapt the distance between adjacent moving units to the gauge along the first direction, thereby achieving the technical effect of improving the simplicity of adjusting the distance between adjacent moving units.

[0017] In an optional implementation manner, the first adjustment structure includes:

There are at least two moving units along the length direction of the track and at least two moving units along the width direction of the track. The adjusting unit is used to adjust the distance between adjacent moving units in the second direction according to the shape of the track, and the second direction forms an angle with the first direction.

[0022] Beneficial effects: The adjusting unit can adjust the distance between adjacent two moving units in the second direction according to the bending shape of the track, that is, the degree of bending of the track. When the moving unit needs to pass through a position with a large degree of bending of the track or a straight position, the adjusting unit can increase the distance between adjacent moving units parallel to the second direction, so that the moving unit can be arranged at the corner position of the base. It can not only pass through the bending position of the track smoothly, but also achieve the technical effect of improving the reliability of the support of the moving unit on the base, avoiding tipping over, and thus achieving the technical effect of improving the use safety of the track camera vehicle. When the moving unit needs to pass through a position with a small degree of bending of the track, the adjusting unit can reduce the distance between adjacent moving units parallel to the second direction, so that the adjusting unit can pass through the bending position of the track smoothly.

[0024] A second adjusting structure is arranged between the first adjusting structure and the base or on the side of the first adjusting structure away from the base. The second adjusting structure is used to adjust the distance between adjacent moving units in the second direction.

[0025] Beneficial effects: By setting the second adjusting structure, the user can adjust the distance between adjacent moving units parallel to the second direction through the second adjusting structure, thereby achieving the technical effect of improving the simplicity of using the track camera vehicle.

[0026] In an alternative embodiment, the track camera vehicle includes:

[0027] A lifting unit is arranged on the side of the base away from the moving unit;

[0028] A supporting unit is arranged on the lifting unit and is used to perform a supporting operation on the component to be supported.

[0029] Beneficial effects: The user can drive the lifting unit to adjust the height of the supporting unit, and further adjust the height of the component to be supported, so that the component to be supported can adapt to the height required for shooting, thereby achieving the technical effects of improving the adaptability and simplicity of using the track camera vehicle.

[0030] In an alternative embodiment, the support unit is rotatably connected to the lifting unit.

[0031] Beneficial effects: By arranging the support unit to be rotatably connected to the lifting unit, it is convenient to meet the requirement of rotational shooting according to actual needs.

[0032] In an alternative embodiment, the support unit includes:

[0033] A support frame, one end of which is connected to the lifting unit;

[0034] A support portion, which is rotatably connected to the other end of the support frame, and the support portion is used to accommodate the piece to be supported.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0061] The following will describe the embodiments of the present invention in conjunction with Figures 1 to 8 , to describe the embodiments of the present invention.

[0062] According to an embodiment of the present invention, on the one hand, there is provided an orbital camera vehicle for use in cooperation with an orbital track. At least two orbital tracks are provided along the width direction of the orbital track itself. The orbital camera vehicle includes:

[0063] A base 1;

[0064] A moving unit 2 is provided on the base 1, and at least two moving units 2 are provided at intervals. At least one moving unit 2 is provided on each orbital track, and the moving unit 2 is in rolling connection with the orbital track;

[0065] An adjustment unit 3 is provided between the base 1 and the moving unit 2, and is at least used to adjust the distance between adjacent moving units 2 along a first direction according to the gauge of the orbital track.

[0066] In the orbital camera vehicle of this embodiment, by providing the adjustment unit 3, the adjustment unit 3 can adjust the distance between adjacent moving units 2 along the first direction, so that the moving unit 2 can be applicable to orbital tracks of various gauges. When the gauge of the orbital track changes, the adjustment unit 3 adjusts the distance between adjacent moving units 2 along the first direction to adapt to the gauge, without the need to manufacture orbital camera vehicles adapted to various gauges in the related art, thereby improving the adaptability of the orbital camera vehicle to different gauges, reducing the number of manufactured orbital camera vehicles, and further achieving the technical effect of saving the shooting cost. At the same time, during the shooting process, only one orbital camera vehicle needs to be carried to adapt to orbital tracks of multiple gauges, reducing the number of orbital camera vehicles required to be carried during the shooting process, so as to achieve the technical effect of reducing the shooting difficulty.

[0067] Among them, in this embodiment, the gauge refers to the distance between two orbital tracks along the width direction of the orbital track, and the width direction of the orbital track is parallel to Figure 1 the Y-axis direction shown. The moving unit 2 is a structure including a roller assembly 204, and a groove matching the roller assembly 204 is provided in the orbital track, so that the moving unit 2 can roll along the length of the orbital track to drive the movement of the base 1 on the orbital track.

[0068] Specifically, in conjunction with Figure 6As shown, the moving unit 2 is a roller assembly 204 with a buffering function. The moving unit 2 includes a support base 201, a guiding part 202, an elastic part 203, and a roller assembly 204. A chute is provided inside the support base 201. One end of the guiding part 202 is slidably connected inside the chute, the other end of the guiding part 202 is connected to the roller assembly 204, one end of the elastic part 203 is connected to the support base 201, and the other end of the elastic part 203 is connected to the roller assembly 204.

[0069] Among them, the elastic part 203 can be a spring. The elastic part 203 is in a compressed state. When subjected to bumps or impact forces in other directions, since the elastic part 203 can expand and contract, the roller assembly 204 and the guiding part 202 can move reciprocally in the chute along Figure 6 the vertical direction shown, so that the elastic part 203 repeatedly stores and releases elastic potential energy, thereby playing a buffering role, and further achieving the technical effect of improving the stability and reliability of the use of the rail camera car.

[0070] As an alternative embodiment, it can also be that the moving unit 2 is a slider, and a slideway matching the slider is provided inside the rail, which can also enable the moving unit 2 to move along the length direction of the rail. Or, the moving unit 2 is only a roller assembly 204 without a buffering function.

[0071] Of course, in other embodiments, according to the different designs of the rail camera car, the specific structures of the moving unit 2 and the rail are adjusted. Or, the specific type of the elastic part 203 is adjusted.

[0072] In addition, as combined with Figure 8 shown, in this embodiment, 4 moving units 2 are provided and are respectively arranged at the turning positions close to the base 1. Among them, the connection line between any two adjacent moving units 2 is parallel to Figure 1 the X-axis or the Y-axis in

[0073] Of course, in other embodiments, according to the different designs of the rail camera car, the number and installation positions of the moving units 2 are adjusted.

[0074] In addition, as combined with Figure 3 shown, in this embodiment, the adjustment unit 3 includes:

[0075] A first adjustment structure 301, which is arranged on the base 1. The first adjustment structure 301 is connected to each moving unit 2, that is, connected to the support base 201 of the moving unit 2, and is used to adjust the distance between adjacent moving units 2 along the first direction.

[0076] Among them, in this embodiment, the first direction is parallel to the Y-axis direction shown in Figure 1 , that is, the horizontal direction shown in Figure 3 shown.

[0077] By providing the first adjustment structure 301, the user can drive the first adjustment structure 301 to move the adjacent distance of the unit 2 along the first direction to adapt to the gauge, thereby achieving the technical effect of improving the simplicity of adjusting the distance between adjacent moving units 2.

[0078] Specifically, as shown in Figure 3 , in this embodiment, the first adjustment structure 301 includes:

[0079] A first rotating part 3011, rotatably connected to the base 1. The first rotating part 3011 is provided with threads of a first rotation direction and threads of a second rotation direction, and the first rotation direction and the second rotation direction are opposite;

[0080] There are two sliding parts 3012. Each sliding part 3012 is provided with a threaded hole that matches the thread. The threaded hole of one sliding part 3012 is in transmission connection with the thread of the first rotation direction, and the threaded hole of the other sliding part 3012 is in transmission connection with the thread of the second rotation direction, and is used to move the two sliding parts 3012 along the direction of approaching or separating from each other as the first rotating part 3011 rotates.

[0081] Among them, the first rotating part 3011 is a transmission lead screw, and the sliding part 3012 is a lead screw nut. Through the threaded connection of the transmission lead screw and the lead screw nut, the rotation of the transmission lead screw can adjust the distance between the two sliding parts 3012.

[0082] Further, each sliding part 3012 extends along a direction parallel to the Figure 1 shown X-axis direction. Two moving units 2 are provided on one sliding part 3012, so that in this embodiment, by providing one first rotating part 3011 and two sliding parts 3012, the adjustment of the interval between two pairs of moving units 2 along the first direction can be realized.

[0083] Preferably, as shown in Figure 3 , a receiving cavity is provided on the base 1. The first rotating part 3011 and the sliding part 3012 are both arranged in the receiving cavity. The first adjustment structure 301 includes a driving part 3013, one end of which is arranged on the base 1, and the other end of the driving part 3013 penetrates into the receiving cavity and is fixedly connected to the first rotating part 3011 to drive the first rotating part 3011 to rotate counterclockwise or clockwise. Based on this, manual adjustment is not required, thereby achieving the technical effect of improving the simplicity of using the rail camera vehicle.

[0084] As a transformable embodiment, it is also possible that the first adjustment structure 301 does not include the driving part 3013. Or, the number of sliding parts 3012 corresponds one-to-one to the number of moving units 2. At this time, the number of the first rotating parts 3011 and the driving parts 3013 are both two. Or, the driving part 3013 is detachably connected to the first rotating part 3011.

[0085] Of course, in other embodiments, according to the different designs of the rail camera vehicle, the specific direction of the first direction, the number of the first adjustment structures 301, the specific structure of the first adjustment structures 301, the quantitative relationship between the first adjustment structures 301 and the moving units 2, the number of the first rotating parts 3011, the number of the sliding parts 3012, and the number of the driving parts 3013 are adjusted.

[0086] In addition, as shown in Figure 5 、 6 and 8, in this embodiment, the adjustment unit 3 is used to adjust the distance between adjacent moving units 2 along the second direction according to the bending shape of the rail, and the second direction forms an angle with the first direction. That is, the second direction refers to the direction parallel to the X-axis direction as shown in Figure 1 , that is, the second direction refers to the horizontal direction as shown in Figure 5 .

[0087] Among them, the bending shape of the rail refers to the degree of bending of the rail. That is to say, the rail is not limited to a straight line shape and there are turning positions. According to different scenes to be photographed, the turning radius is different. For a rail with a small turning radius, the distance between the rail camera vehicle along the X-axis direction parallel to that shown in Figure 1 should be correspondingly reduced. For a position with a large turning radius, although the distance can also be adapted, since the distance in the X-axis direction is small, it will also cause the problem of the rail camera vehicle being top-heavy and affecting the running stability of the rail camera vehicle.

[0088] In this application, by setting the adjustment unit 3, the adjustment unit 3 can adjust the distance between adjacent two moving units 2 along the second direction according to the bending shape of the rail, that is, the degree of bending of the rail. When the moving unit 2 needs to pass through a position with a large degree of bending of the rail or a straight line position, the adjustment unit 3 can increase the distance between adjacent moving units 2 parallel to the X-axis direction as shown in Figure 1 , so that the moving unit 2 can be arranged at the corner position of the base 1, which can not only smoothly pass through the bending position of the rail, but also achieve the technical effect of improving the reliability of the support of the moving unit 2 for the base 1, avoiding rollover, and thus achieving the technical effect of improving the use safety of the rail camera vehicle. When the moving unit 2 needs to pass through a position with a small degree of bending of the rail, the adjustment unit 3 can reduce the distance between adjacent moving units 2 parallel to the X-axis direction as shown in Figure 1The spacing in the X-axis direction shown, so that the adjustment unit 3 can smoothly pass through the curved position of the track.

[0089] In addition, in this embodiment, the adjustment unit 3 includes a second adjustment structure 302, which is arranged on the side of the first adjustment structure 301 away from the base 1, that is, combined Figure 5 As shown, the base 1 is arranged above the first adjustment structure 301, the second adjustment unit 3 is arranged below the first adjustment unit 3, and the second adjustment structure 302 is used to adjust the spacing of the moving unit 2 in the second direction. By setting the second adjustment structure 302, the user can, through the second adjustment structure 302, adjust the distance between adjacent moving units 2 along the Figure 1 X-axis direction shown, so as to achieve the technical effect of improving the simplicity of using the track camera vehicle.

[0090] Among them, combined Figures 1 to 5 As shown, the second adjustment structure 302 includes a first housing 3022 and a driving structure 3021. Two first housings 3022 are arranged at intervals in the Figure 1 Y-axis direction shown. Each first housing 3022 is provided with an installation cavity, and the number of installation cavities is the same as the number of driving structures 3021 arranged on the first housing 3022. Two driving structures 3021 are arranged on each first housing 3022, that is, two installation cavities are arranged on each first housing 3022, and the driving structure 3021 is arranged in the installation cavity.

[0091] Specifically, the length direction of the driving structure 3021 is arranged along the Figure 5 horizontal direction shown. The two driving structures 3021 are arranged back to back, that is, the fixed ends of the two driving structures 3021 are arranged close to each other, Figure 5 As shown, the telescopic end of the driving structure 3021 located at the left end is arranged away from the driving structure 3021 at the right end, Figure 5 The telescopic end of the driving structure 3021 located at the right end shown is arranged away from the driving structure 3021 at the left end.

[0092] Among them, the driving structure 3021 can be an electric push rod, so that the driving structure 3021 can adjust the position of the moving unit 2 along the Figure 5 horizontal direction shown, improve the adaptability of the spacing between adjacent moving units 2 in the second direction to different bending degrees of the track, and thus achieve the technical effect of improving the applicability of the track camera vehicle.

[0093] As a transformable embodiment, it is also possible that the second adjustment structure 302 is provided between the first adjustment structure 301 and the base 1. At this time, the first adjustment structure 301 includes a second housing. The number of the second housings is two, and each second housing is connected to the base 1 through the second adjustment structure 302. Among them, the fixed end of the second adjustment structure 302 is connected to the base 1, and the adjustment end of the second adjustment structure 302 is connected to the second housing. The number of the first rotating parts 3011 is two. One first rotating part 3011 and two sliding parts 3012 are provided in each second housing. Two sliding parts 3012 are threadedly connected to each first rotating part 3011. By driving the two second housings to move along Figure 1 the X-axis direction shown to realize the adjustment of the distance between adjacent adjustment structures in the second direction.

[0094] Of course, in other embodiments, according to the different designs of the rail camera vehicle, the number of the driving structures 3021, the orientation of the telescopic ends, and the number of the first housings 3022 are adjusted. For example, the number of the driving structures 3021 is set in one-to-one correspondence with the number of the second adjustment structures 302. Or, the specific structure of the second adjustment structure 302 is adjusted.

[0095] In addition, as shown in Figures 1 to 6 , in this embodiment, the rail camera vehicle includes:

[0096] A lifting unit 4, which is provided on the side of the base 1 away from the moving unit 2, that is, above the base 1 shown in Figure 2 ;

[0097] A supporting unit 5, which is provided on the lifting unit 4 and is used for supporting the piece to be supported.

[0098] Among them, the piece to be supported is a camera. The lifting unit 4 can be a hydraulic push rod, and multiple lifting units 4 can be provided. The multiple lifting units 4 are uniformly arranged in the circumferential direction.

[0099] Based on this, the user can drive the lifting unit 4 to realize the height adjustment of the supporting unit 5, and further realize the height adjustment of the piece to be supported, so that the piece to be supported can adapt to the height required for shooting, thereby achieving the technical effects of improving the adaptability and ease of use of the rail camera vehicle.

[0100] Specifically, the supporting unit 5 includes:

[0101] A support frame 501, one end of which is connected to the lifting unit 4;

[0102] A supporting part 502, which is rotatably connected to the other end of the support frame 501 and can rotate relative to the support frame 501. The supporting part 502 is used for supporting and fixing the piece to be supported.

[0103] Among them, in combination with Figure 3 As shown, a fixed cavity is provided inside the support frame 501. The support part 502 includes a first support member 5021, a second rotating part 5023, and a rotating rod 5024. The fixed end of the second rotating part 5023 is connected inside the fixed cavity, and the rotating end of the second rotating part 5023 is connected to one end of the rotating rod 5024. The other end of the rotating rod 5024 passes through the fixed cavity and is connected to the first support member 5021. The first support member 5021 is used to accommodate the member to be supported.

[0104] The second rotating part 5023 drives the rotating rod 5024 to rotate relative to the support frame 501, so that the first support member 5021 can rotate around the axis of the second rotating part 5023 accordingly, in order to meet the needs of rotating shooting according to actual requirements.

[0105] Specifically, the second rotating part 5023 is a motor, the rotating rod 5024 is a rotating shaft, and the first support member 5021 is a disc-shaped structure.

[0106] Preferably, in combination with Figure 3 As shown, the inner wall of the fixed cavity in contact with the rotating rod 5024 is provided with a groove, and a plurality of balls 5025 are provided in the groove. The rotating rod 5024 is in rolling connection with the balls 5025, which can reduce the friction force that the rotating rod 5024 needs to resist during rotation, thereby reducing the force required for the second rotating part 5023 to drive the rotating rod 5024 to rotate, and further achieving the technical effect of saving energy required when using the rail camera car. At the same time, it can also achieve the technical effect of improving the rotation smoothness of the rotating rod 5024.

[0107] Furthermore, the support part 502 includes a second support member 5022, which is arranged on the first support member 5021. Specifically, the second support member 5022 is arranged on a fixing plate. The fixing plate is provided with a sleeve hole and is sleeved on the rotating rod 5024, so that the second support member 5022 can rotate along with the rotating rod 5024, and the second support member 5022 is used to accommodate the user.

[0108] Among them, the second support member 5022 can be a chair. Based on this, the user can sit on the rail camera car for shooting, and the second support member 5022 can rotate synchronously with the member to be supported, which can not only improve the simplicity of using the rail camera car, but also achieve the technical effects of improving the labor-saving property of shooting and the shooting quality.

[0109] As a changeable implementation manner, it can also be that the support part 502 does not include the second support member 5022, or the specific structure of the second support member 5022 is adjusted. Or, the inner wall of the fixed cavity is not provided with the groove and the balls 5025, and the rotating rod 5024 and the balls 5025 are in sliding connection.

[0110] Of course, in other embodiments, according to the different designs of the rail camera vehicle, the types of the support members to be supported, the types, quantities, and arrangement modes of the lifting units 4 are adjusted.

[0111] In other embodiments, according to the different designs of the rail camera vehicle, the types of the second rotating part 5023 and the rotating rod 5024 and the shape of the first support member 5021 are adjusted.

[0112] As a transformable implementation manner, it may also be that the rail camera vehicle does not include the support unit 5.
