DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0030] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0031] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the electric photographic slide according to the embodiment of the present application includes a slide 10, on which is provided a power assembly 20, a locking assembly 30 and a movable slide 40, the power assembly 20 is transmission-connected with the slide 40 to drive the slide 40 to move along the slide 10, the power assembly 20 includes a power part 21 and a transmission member 22, the power part 21, the transmission member 22 and the slide 40 are transmission-connected in sequence, the locking assembly 30 includes a locking member 31, and the locking member 31 is movable to engage with or space the transmission member 22.

[0032] In detail, the slide 40 is used to install photographic equipment, and the power component 20 is connected to the slide 40 in a transmission manner, so that the power component 20 can provide power for the slide 40 to move on the slide rail 10, and the locking member 31 can move to engage with or space the transmission member 22. When the locking member 31 moves to a position engaged with the transmission member 22, the transmission member 22 is locked and the slide 40 cannot move. When the transmission member 22 moves to a position spaced from the transmission member 22, the power unit 21 can drive the transmission member 22 to move (the movement of the transmission member 22 includes at least one of translation and rotation) to drive the slide 40 to move (the movement of the slide 40 includes translation).

[0033] The power unit 21 may be a cylinder or an electric motor.

[0034] According to the electric photographic slide rail of the embodiment of the present application, the transmission member 22 can be locked or unlocked by controlling the movement of the locking member 31. The operation is simple and reliable, which improves the convenience of using the electric photographic slide rail and avoids the possibility of deformation of the slide rail 10 in the prior art.

[0035] like Figure 4 and Figure 5 As shown, according to the electric photographic slide of the embodiment of the present application, the locking assembly 30 also includes a first reset member 32, and the electric photographic slide also includes a shell 50. The power assembly 20, the first reset member 32 and the locking member 31 are all arranged in the shell 50, and the first reset member 32 is clamped between the locking member 31 and the shell 50. The first reset member 32 provides a force for the locking member 31 to engage with the transmission member 22.

[0036] In detail, the locking assembly 30 also includes a first reset member 32. The power assembly 20, the first reset member 32 and the locking member 31 are all arranged in the housing 50. The housing 50 can be used to fix and protect the power assembly 20, the first reset member 32 and the locking member 31. The first reset member 32 is clamped between the locking member 31 and the housing 50. The first reset member 32 provides the locking member 31 with a force for engaging with the transmission member 22. That is to say, when the locking member 31 is not subjected to other forces outside the first reset member 32, the locking member 31 is pressed against the transmission member 22 under the force of the first reset member 32, and engages with the transmission member 22. The transmission member 22 is engaged. When the locking member 31 needs to be spaced from the transmission member 22, a driving force needs to be applied to overcome the force of the first reset member 32 to move the locking member 31 to be spaced from the transmission member 22. At this time, the first reset member 32 is deformed and compressed or stretched. When the driving force disappears, the first reset member 32 resets and drives the locking member 31 to reset and lock with the transmission member 22. In this way, the first reset member 32 can be used to reduce the difficulty of locking or disengaging the locking member 31 from the transmission member 22, and improve the reliability of the engagement, thereby ensuring that the slide 40 is firmly locked by locking the transmission member 22 when the slide 40 does not need to move.

[0037] The first reset member 32 may be a spring, a spring, a rubber, a rubber band, etc. The spring includes a torsion spring, a tension spring, a compression spring, an air spring, etc., and a suitable structure may be selected according to actual needs, and this application does not limit this.

[0038] like Figure 2-Figure 5 As shown, in some embodiments, the electric photographic slide also includes a button assembly 60, which is movably disposed on the shell 50. The button assembly 60 includes a toggle member 61, which is movable between a first position and a second position. When the toggle member 61 is in the first position, the locking member 31 is engaged with the transmission member 22. When the toggle member 61 is in the second position, the locking member 31 and the toggle member 61 are stopped and spaced apart from the transmission member 22.

[0039] In detail, the electric photographic slide also includes a button assembly 60, which is movably arranged on the shell 50, that is, when a force is applied to the button assembly 60, the button assembly 60 can be pushed to move on the shell 50, and the toggle member 61 is movable between a first position and a second position, that is, applying a force to the button assembly 60 can push the toggle member 61 to move from the first position to the second position, or from the second position to the first position. When the driving force applied to the toggle member 61 is less than the force of the first reset member 32 to be overcome, under the push of the first reset member 32, the toggle member 61 moves from the first position to the second position, and the locking member 31 gradually approaches the transmission member 22 and finally engages with the transmission member 22. When the driving force applied to the toggle member 61 is greater than the force of the first reset member 32 to be overcome, the toggle member 61 pushes the locking member 31 to separate and space the transmission member 22.

[0040] According to the electric photographic slide rail of the embodiment of the present application, by applying force to the toggle member 61 to unlock the locking member 31, the difficulty of the user directly operating the locking member 31 can be reduced, and the user can also be prevented from directly touching the locking member 31.

[0041] Among them, when the toggle member 61 is in the first position, the locking member 31 is spaced apart from or in contact with the toggle member 61; when the toggle member 61 is in the first position, the locking member 31 is spaced apart from the toggle member 61 so that when the toggle member 61 is accidentally touched, it will not touch the locking member 31 due to the certain distance from the locking member 31, thereby improving safety and reliability.

[0042] like Figure 3 and Figure 5As shown, in some embodiments, a first locking groove and a second locking groove are provided on the shell 50, and the button assembly 60 includes a mating piece 62, which is connected to the toggle piece 61, and a locking portion 621 is provided on the mating piece 62. When the toggle piece 61 is in the first position, the locking portion 621 is clamped in the first locking groove, and when the toggle piece 61 is in the second position, the locking portion 621 is clamped in the second locking groove.

[0043] In detail, the matching piece 62 is connected to the toggle piece 61, and a locking portion 621 is provided on the matching piece 62. When the toggle piece 61 is in the first position, the locking portion 621 is clamped in the first locking groove. In this way, the toggle piece 61 is fixed at the first position by limiting the locking portion 621 by the first locking groove. When the locking portion 621 is disengaged from the first locking groove and the matching piece 62 is moved to drive the toggle piece 61 to the second position, the locking portion 621 is clamped in the second locking groove. In this way, the toggle piece 61 is fixed at the second position by limiting the locking portion 621 by the second locking groove.

[0044] The matching member 62 and the toggle member 61 may be fixedly connected or movably connected, and the present application does not impose any limitation thereto, as long as linkage can be achieved in the directions of the first position and the second position.

[0045] like Figure 6 As shown, in some embodiments, a sliding groove 53 extending along the first direction is provided on the shell 50, the matching piece 62 is slidably disposed in the sliding groove 53, a second reset piece 70 is clamped between the matching piece 62 and the toggle piece 61, and the first locking groove and the second locking groove are spaced apart along the first direction.

[0046] Specifically, when the locking portion 621 is stuck in the first locking groove, the matching piece 62 is pressed. Since the second reset piece 70 is sandwiched between the matching piece 62 and the toggle piece 61, the matching piece 62 can be compressed by pressing the second reset piece 70, thereby generating a displacement in the axial direction of the sliding groove 53, so that the locking portion 621 can be disengaged from the first locking groove. After the locking portion 621 is disengaged from the first locking groove, the matching piece 62 is moved along the sliding groove 53, and the movement of the matching piece 62 drives the toggle piece 61 to move, so that the toggle piece 61 is moved from the first locking groove to the second reset piece 70. The locking member 31 is moved from the first position to the second position. At this time, the locking member 31 is also spaced apart from the transmission member 22 under the action of the toggle member 61, and the matching member 62 is released. The matching member 62 pushes the locking portion 621 into the second locking groove under the resetting force of the second resetting member 70. In this way, the second resetting member 70 can simplify the difficulty of the locking portion 621 of the matching member 62 pushing into the locking groove (the first locking groove and the second locking groove) or out of the locking groove, thereby realizing the positioning of the matching portion at the corresponding first position and the second position, so that the toggle member 61 can be fixed at the first position or the second position.

[0047] The second reset member 70 may be a spring, a spring, a rubber, a rubber band, etc. The spring includes a torsion spring, a tension spring, a compression spring, an air spring, etc., and a suitable structure may be selected according to actual needs, and this application does not limit this.

[0048] like Figure 3 As shown, in some embodiments, one of the fitting member 62 and the locking member 31 is provided with a guide post 63 , and the other is provided with a guide groove 623 , and the guide post 63 passes through the guide groove 623 .

[0049] According to the electric photographic slide rail of the embodiment of the present application, a guide column 63 is provided on one of the matching member 62 and the locking member 31, and a guide groove 623 is provided on the other, and the guide column 63 is inserted into the guide groove 623. In this way, when the matching member 62 presses against the second reset member 70 and the second reset member 70 drives the matching member 62 to move in a direction away from the toggle member 61, it can ensure that the matching member 62 can move along a predetermined trajectory without shifting, thereby avoiding the possible jamming phenomenon when the second reset member 70 is shifted, and improving the reliability of the movement of the matching member 62.

[0050] like Figure 3 As shown, in some embodiments, a plurality of guide posts 63 are provided on the toggle member 61, and the plurality of guide posts 63 are arranged around the second reset member 70. At least one limiting portion 611 is also provided at the edge of the toggle member 61, and at least one mating groove 622 is provided on the mating member 62, and the limiting portion 611 can be movably located in the mating groove 622.

[0051] In detail, a plurality of guide posts 63 are provided on the toggle member 61, and the plurality of guide posts 63 are arranged around the second reset member 70, so that the mating member 62 can be guided in multiple directions, thereby ensuring the controllable extension and retraction of the second reset member 70 and avoiding sticking due to displacement; and by utilizing the limiting portion 611 and the mating groove 622, on the one hand, the stable movement of the mating member 62 can be further guaranteed, and on the other hand, when the toggle member 61 and the mating member 62 are assembled, it can also play a role in positioning and anti-mistake, thereby reducing the difficulty of assembling the toggle member 61 and the mating member 62.

[0052] like Figure 3 and Figure 5 As shown, in some embodiments, the button assembly 60 further includes a button 65, which is connected to the matching piece 62 for user operation.

[0053] like Figure 5As shown, in some embodiments, the locking member 31 includes a fixed end and a working end, the fixed end of the locking member 31 is rotatably connected to the shell 50, and the working end of the locking member 31 is provided with a guide slope 311, the guide slope 311 is used to cooperate with the toggle member 61, and the guide slope 311 is inclined in a direction gradually away from the fixed end of the locking member 31 toward a direction gradually approaching the transmission member 22.

[0054] Specifically, the fixed end of the locking member 31 is rotatably connected to the shell 50, which not only realizes the positioning and fixation between the locking member 31 and the shell 50, but also enables the locking member 31 to move only along a predetermined trajectory, thereby improving the locking or spacing movement efficiency and reliability between the locking member 31 and the transmission member 22; the working end of the locking member 31 is provided with a guide bevel 311, because when the toggle member 61 and the locking member 31 are stopped, the toggle member 61 stops on the guide bevel 311, and the locking member 31 is rotating and the toggle member 61 is moving up and down, and the movement trajectories of the two are different. The guide bevel 311 is inclined in the direction of gradually moving away from the fixed end of the locking member 31 toward the direction of gradually approaching the transmission member 22, which can ensure that the toggle member 61 can always push against the locking member 31 during the movement.

[0055] In some embodiments, the transmission member 22 is a gear structure, the transmission member 22 is provided with a plurality of first gear teeth, the locking member 31 is provided with a plurality of second gear teeth, and when the locking member 31 is engaged with the transmission member 22, the second gear teeth mesh with the first gear teeth.

[0056] According to the electric photographic slide rail of the embodiment of the present application, the transmission member 22 is set as a gear structure, and the first gear teeth on the transmission member 22 and the second gear teeth on the locking member 31 are engaged with each other, which can reduce the difficulty of engaging and disengaging the locking member 31 and the transmission member 22, while ensuring the reliability of the locking member 31 locking the transmission member 22.

[0057] In some embodiments, the transmission member 22 and the power unit 21 are connected to each other through a first transmission belt assembly, and the transmission member 22 and the slide 40 are connected to each other through a second transmission belt assembly.

[0058] According to the electric photographic slide rail of the embodiment of the present application, the transmission belt can realize transmission when the distance between the two axes is large, and the transmission is smooth, buffering and vibration absorption. Therefore, the first transmission belt assembly is used for transmission between the transmission member 22 and the output shaft of the power unit 21, and the position of the transmission member 22 and the position of the locking member 31 can be reasonably set. The transmission member 22 and the slide 40 are connected by the second transmission belt assembly, which can improve the reliability of the transmission connection between the transmission member 22 and the slide 40.
