[0018] In order to make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] Please refer to Figures 1-4 As shown, in a first aspect, the present application provides a horizontal and vertical shooting switching device 1, which can effectively reduce or even avoid the possibility that the arc-shaped guide rail 30 rolls over and disengages from the support base 10 during the sliding process relative to the support base 10.

[0020] The horizontal and vertical shooting switching device 1 includes a support base 10, a cover plate 20, and an arc-shaped guide rail 30. The support base 10 is used to connect external devices. The cover plate 20 is connected to the support base 10, and an installation space is formed after the cover plate 20 and the support base 10 are installed. The arc-shaped guide rail 30 is used to connect the photographic device 2. The arc-shaped guide rail 30 is disposed through the installation space. The arc-shaped guide rail 30 is configured with a first side wall 31 and a second side wall 32 that are relatively arranged front and back, and a bottom wall 33 connected between the first side wall 31 and the second side wall 32. The first side wall 31 and the second side wall 32 have upper and lower surfaces that are relatively arranged. The upper surface abuts against the cover plate 20, and the lower surface abuts against the support base 10.

[0021] The following will Figures 1-9 expand and introduce the specific structure of the horizontal and vertical shooting switching device 1.

[0022] As Figures 1-2 shown, the horizontal and vertical shooting switching device 1 has a horizontal shooting state and a vertical shooting state; among them, the "horizontal shooting state" is understood as a usage mode in which the horizontal and vertical shooting switching device 1 can enable the photographic device 2 to perform horizontal shooting; the "vertical shooting state" is understood as a usage mode in which the horizontal and vertical shooting switching device 1 can enable the photographic device 2 to perform vertical shooting.

[0023] As Figures 3-4 shown, the horizontal and vertical shooting switching device 1 includes a support base 10, a cover plate 20, and an arc-shaped guide rail 30.

[0024] The support base 10 serves as a support structure of the horizontal and vertical shooting switching device 1 for supporting structural members such as the arc-shaped guide rail 30; the specific structure of the support base 10 will be expanded and introduced below.

[0025] The support base 10 is used to connect external components; among them, the external components can include, but are not limited to, a tripod or a stabilizer. The specific connection method between the support base 10 and the external components is not limited herein, and designers can make reasonable designs according to actual needs; for example, the support base 10 can be detachably connected to the external components by at least one of screwing, clamping, or plugging.

[0026] The cover plate 20 serves as a limiting structure of the horizontal and vertical shooting switching device 1 and is used in cooperation with the support base 10 to effectively reduce or even avoid the possibility that the arc-shaped guide rail 30 rolls over and detaches from the support base 10 during the sliding process relative to the support base 10.

[0027] The cover plate 20 is connected to the support base 10. The specific connection method between the cover plate 20 and the support base 10 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the cover plate 20 can be detachably connected to the support base 10 by at least one of screw connection, snap connection or plug connection, etc.; for another example, the cover plate 20 can also be non-detachably connected to the support base 10 by bonding, injection molding or 3D printing, etc.

[0028] An installation space is formed after the cover plate 20 and the support base 10 are installed; the installation space is an area formed by the cover plate 20 and the support base 10 jointly enclosing for installing the arc-shaped guide rail 30.

[0029] As Figures 3-4 shown, the arc-shaped guide rail 30 serves as a track structure of the horizontal and vertical shooting switching device 1 and is used to drive the photographic device 2 to slide along a preset track, so that the horizontal and vertical shooting switching device 1 can switch between the horizontal shooting state and the vertical shooting state. The arc-shaped guide rail 30 can be, but not limited to, circular arc-shaped or parabolic-like; among them, when the arc-shaped guide rail 30 is circular arc-shaped, the arc-shaped guide rail 30 can be, but not limited to, a quarter circular arc guide rail, a half circular arc guide rail, a three-quarter circular arc guide rail or a full circular arc guide rail, etc.

[0030] The arc-shaped guide rail 30 is used to connect the photographic device 2. The specific connection method between the arc-shaped guide rail 30 and the photographic device 2 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the horizontal and vertical shooting switching device 1 can further include a quick-release module 60, and the photographic device 2 is detachably connected to the arc-shaped guide rail 30 through the quick-release module 60. Since the quick-release module 60 is not the main innovation point of this application, the specific structure of the quick-release module 60 is not limited here, and the designer can directly adopt similar methods such as snap connection in related technologies to directly replace it according to actual needs.

[0031] The arc-shaped guide rail 30 is passed through the installation space to be clamped between the cover plate 20 and the support base 10.

[0032] The arc-shaped guide rail 30 is configured with a first side wall 31 and a second side wall 32 that are oppositely arranged front and back, and a bottom wall 33 connecting between the first side wall 31 and the second side wall 32; the first side wall 31 and the second side wall 32 have upper and lower surfaces that are oppositely arranged; the upper surface abuts against the cover plate 20; the lower surface abuts against the support base 10.

[0033] Based on the vertical and horizontal shooting switching device 1 in the embodiments of the present application, by designing the cover plate 20, the cover plate 20 is connected to the support base 10 to form an installation space, and the arc-shaped guide rail 30 passes through the installation space and is clamped between the cover plate 20 and the support base 10. The lower surfaces of the first side wall 31 and the second side wall 32 are in contact with the support base 10, and the upper surfaces of the first side wall 31 and the second side wall 32 are in contact with the cover plate 20. In this way, the cover plate 20 can play a limiting role on the arc-shaped guide rail 30, so as to effectively reduce or even avoid the possibility that the arc-shaped guide rail 30 rolls over and detaches from the support base 10 during the sliding process relative to the support base 10.

[0034] As Figure 3 and Figure 5 shown, the bottom wall 33 is configured with an arc-shaped through groove 331. The support base 10 includes a base body 11 and a connecting column 12; the top surface of the base body 11 is used to support the lower surfaces of the first side wall 31 and the second side wall 32; the connecting column 12 is vertically arranged on the top surface of the base body 11, and the connecting seat can pass through the arc-shaped through groove 331; the cover plate 20 is connected to the connecting column 12.

[0035] Among them, the base body 11 serves as the supporting main body of the support base 10; the specific shape of the base body 11 is not limited here, and designers can make reasonable designs according to actual needs; for example, the base body 11 can be, but not limited to, a cuboid shape or a quasi-cylindrical shape.

[0036] The connecting column 12 serves as the connecting main body of the support base 10; the number of the connecting columns 12 can be one or more (more than two). The specific connection method between the connecting column 12 and the base body 11 is not limited here, and designers can make reasonable designs according to actual needs; for example, the connecting column 12 can be, but not limited to, detachably connected to the base body 11 by at least one of screwing, clamping or plugging; again, for example, the connecting column 12 can also be, but not limited to, non-detachably connected to the base body 11 by gluing, injection molding or 3D printing. The specific connection method between the cover plate 20 and the connecting column 12 is not limited here, and designers can make reasonable designs according to actual needs; for example, the cover plate 20 can be, but not limited to, detachably connected to the connecting column 12 by at least one of screwing, clamping or plugging; again, for example, the cover plate 20 can also be, but not limited to, non-detachably connected to the connecting column 12 by gluing, injection molding or 3D printing.

[0037] By designing an arc-shaped through groove 331 on the bottom wall 33 of the arc-shaped guide rail 30, the connecting column 12 passes through the arc-shaped through groove 331 and is connected to the cover plate 20, so that the arc-shaped guide rail 30 is clamped between the cover plate 20 and the seat body 11, and the lower surfaces of the first side wall 31 and the second side wall 32 of the cover plate 20 abut against the top surface of the seat body 11. In this way, the cover plate 20 can restrict the arc-shaped guide rail 30, effectively reducing or even avoiding the possibility that the arc-shaped guide rail 30 rolls over and disengages from the support seat 10 during the sliding process relative to the support seat 10.

[0038] As Figure 3 and Figure 5 shown, the cover plate 20 has a curvature adapted to the arc-shaped guide rail 30. The cover plate 20 is connected to the free end of the connecting column 12. After the cover plate 20 is connected to the connecting column 12, an installation space is formed between the bottom surface of the cover plate 20 and the top surface of the seat body 11. By designing the cover plate 20 to have a curvature adapted to the arc-shaped guide rail 30, the upper surfaces of the first side wall 31 and the second side wall 32 of the arc-shaped guide rail 30 clamped between the cover plate 20 and the seat body 11 can be adapted and fitted to the bottom surface of the cover plate 20, increasing the contact area between the first side wall 31 and the second side wall 32 of the arc-shaped guide rail 30 and the cover plate 20, so as to ensure the movement stability of the arc-shaped guide rail 30 during the sliding process relative to the support seat 10.

[0039] The number of the connecting columns 12 is two; the cover plate 20 is connected to the two connecting columns 12 by screws. Among them, the two connecting columns 12 are symmetrically arranged about the central axis of the seat body 11. By designing two connecting columns 12, two support points are formed between the two connecting columns 12 and the cover plate 20, so as to enhance the connection stability between the cover plate 20 and the support seat 10; the cover plate 20 and the two connecting columns 12 are connected by screwing, so as to reduce the assembly difficulty between the cover plate 20 and the support seat 10.

[0040] As Figure 3 and Figure 5 shown, a bushing 13 is sleeved on the column body of the connecting column 12. The connecting column 12 passes through the arc-shaped through groove 331, so that the bushing 13 contacts the groove wall surface of the arc-shaped through groove 331, so as to avoid the direct contact between the connecting column 12 and the groove wall surface of the arc-shaped through groove 331, thereby avoiding the possibility of wearing the connecting column 12 due to direct contact with the connecting column 12 during the sliding process of the arc-shaped guide rail 30 relative to the support seat 10.

[0041] The bushing 13 can rotate around the axis of the connecting column 12. The connecting column 12 passes through the arc-shaped through groove 331, so that the bushing 13 is in contact with the groove wall surface of the arc-shaped through groove 331. When the arc-shaped guide rail 30 slides relative to the support base 10, the bushing 13 will rotate around the axis of the connecting column 12, so that when the arc-shaped guide rail 30 slides relative to the support base 10, rolling friction will be generated between the bushing 13 and the arc-shaped guide rail 30. On the one hand, this facilitates the sliding of the arc-shaped guide rail 30, and on the other hand, it can also reduce the wear degree of the mutual friction between the bushing 13 and the arc-shaped guide rail 30.

[0042] As Figures 5-9 shown, a jack 21 is provided in the middle of the cover plate 20; the horizontal and vertical shooting switching device 1 further includes a locking member 40 and a unlocking member 50; one end of the locking member 40 is slidably connected to the jack 21, a pressing portion 43 for pressing the bottom wall 33 is provided in the middle of the locking member 40, and the other end of the locking member 40 is connected to one end of the unlocking member 50; the unlocking member 50 is horizontally arranged, and the end of the unlocking member 50 away from the locking member 40 is exposed outside the seat body 11; the locking member 40 can move vertically under the drive of the unlocking member 50 to lock or unlock the arc-shaped guide rail 30.

[0043] The locking member 40 has a locking state and an unlocking state, and the unlocking member 50 can drive the locking member 40 to move vertically to switch the locking member 40 between the locking state and the unlocking state; in the locking state, the locking member 40 moves vertically downward to make the pressing portion 43 press the bottom wall 33 of the arc-shaped guide rail 30 to lock the arc-shaped guide rail 30 and realize the relative fixation of the position between the arc-shaped guide rail 30 and the support base 10; in the unlocking state, the locking member 40 moves vertically upward to make the pressing portion 43 disengage from the bottom wall 33 of the arc-shaped guide rail 30 to unlock the arc-shaped guide rail 30 and realize the relative change of the position between the arc-shaped guide rail 30 and the support base 10. At this time, the user can adjust the position of the arc-shaped guide rail 30 according to actual needs, so that the horizontal and vertical shooting switching device 1 can be switched between the horizontal shooting state and the vertical shooting state.

[0044] The pressing portion 43 is arranged in an inverted cone shape; the arc-shaped through groove 331 has a chamfer adapted to the pressing portion 43. Among them, the pressing portion 43 can be integrally formed with the locking member 40 by injection molding or 3D printing, but is not limited thereto. By designing the pressing portion 43 into an inverted cone shape and designing a chamfer on the groove wall surface of the arc-shaped through groove 331 that is adapted to the inverted cone-shaped pressing portion 43, the contact area between the pressing portion 43 and the groove wall surface of the arc-shaped guide rail 30 can be increased, so as to enhance the stability when the pressing portion 43 presses the arc-shaped guide rail 30.

[0045] As Figures 6-9 shown, the locking member 40 includes a pressing rod 41 and a connecting rod 42; the top of the pressing rod 41 is slidably connected to the jack 21; the pressing portion 43 is arranged in the middle of the pressing rod 41; one end of the connecting rod 42 is connected to the bottom of the pressing rod 41, and the other end of the connecting rod 42 is connected to the unlocking member 50.

[0046] Among them, the crimping part 43 can be integrally formed with the crimping rod 41 by, but not limited to, injection molding or 3D printing. The connection between the connecting rod 42 and the crimping rod 41 can be, but not limited to, a threaded connection.

[0047] By designing the crimping rod 41 and the connecting rod 42, the unlocking member 50 can drive the connected connecting rod 42 to move downward vertically. The movement of the connecting rod 42 drives the connected crimping rod 41 to move downward vertically. The movement of the crimping rod 41 drives the connected crimping part 43 to move downward vertically until the crimping part 43 presses against the bottom wall 33 of the arc-shaped guide rail 30 to lock the arc-shaped guide rail 30, realizing the relative fixation of the position between the arc-shaped guide rail 30 and the support base 10. By designing the crimping rod 41 and the connecting rod 42, the unlocking member 50 can drive the connected connecting rod 42 to move upward vertically. The movement of the connecting rod 42 drives the connected crimping rod 41 to move upward vertically. The movement of the crimping rod 41 drives the connected crimping part 43 to move upward vertically until the crimping part 43 disengages from the bottom wall 33 of the arc-shaped guide rail 30 to unlock the arc-shaped guide rail 30, realizing the relative change of the position between the arc-shaped guide rail 30 and the support base 10. At this time, the user can adjust the position of the arc-shaped guide rail 30 according to actual needs to switch the horizontal-vertical shooting switching device 1 between the horizontal shooting state and the vertical shooting state.

[0048] As Figures 6-9 shown, the unlocking member 50 includes a pushing block 51 and an unlocking rod 52; the pushing block 51 is arranged in the seat body 11, and the pushing block 51 is in inclined surface engagement with the seat body 11. The connecting rod 42 passes through the pushing block 51; the unlocking rod 52 is horizontally arranged, one end of the unlocking rod 52 is in contact with the pushing block 51, and the end of the unlocking rod 52 away from the pushing block 51 is exposed outside the seat body 11.

[0049] By designing the pushing block 51 and the unlocking rod 52, the unlocking rod 52 can push the pushing block 51 to move horizontally. The horizontal movement of the pushing block 51 drives the connecting rod 42 to move vertically downward through inclined plane engagement. The movement of the connecting rod 42 drives the crimping rod 41 connected thereto to move vertically downward. The movement of the crimping rod 41 drives the crimping part 43 connected thereto to move vertically downward until the crimping part 43 presses against the bottom wall 33 of the arc-shaped guide rail 30 to lock the arc-shaped guide rail 30, realizing the relative fixation of the position between the arc-shaped guide rail 30 and the support base 10. By designing the pushing block 51 and the unlocking rod 52, the unlocking rod 52 can push the pushing block 51 to move horizontally. The horizontal movement of the pushing block 51 drives the connecting rod 42 to move vertically upward through inclined plane engagement. The movement of the connecting rod 42 drives the crimping rod 41 connected thereto to move vertically upward. The movement of the crimping rod 41 drives the crimping part 43 connected thereto to move vertically upward until the crimping part 43 disengages from the bottom wall 33 of the arc-shaped guide rail 30 to unlock the arc-shaped guide rail 30, realizing the relative change of the position between the arc-shaped guide rail 30 and the support base 10. At this time, the user can adjust the position of the arc-shaped guide rail 30 according to actual needs so that the horizontal-vertical shooting switching device 1 can be switched between the horizontal shooting state and the vertical shooting state.

[0050] Please refer to Figures 1-2 As shown, in the second aspect, the present application proposes a photography system, which includes a photography device 2 and the above-mentioned horizontal-vertical shooting switching device 1.

[0051] Based on the shooting system in the embodiments of the present application, having the above-mentioned horizontal-vertical shooting switching device 1 can effectively reduce or even avoid the possibility that the arc-shaped guide rail 30 rolls over and disengages from the support base 10 during the sliding process relative to the support base 10.
