Description

Technical Field

[0001] This disclosure relates to the field of support equipment technology, and in particular to a support device, a shooting system, and a vehicle. Background Technology

[0002] To improve shooting quality and meet the shooting needs from different angles, the shooting device can use a gimbal or other support equipment that can be adjusted in angle for support and stability.

[0003] In related technologies, in order to keep the shooting device stable, a continuous holding force needs to be provided by the driving device, which results in high power consumption and obvious heat generation problems for the driving device. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this disclosure provides a support device, a shooting system, and a vehicle.

[0005] According to a first aspect of the present disclosure, a support device is provided, comprising:

[0006] First support section;

[0007] The second support part is rotatably connected to the first support part;

[0008] A first driving device is used to drive the first support part and the second support part to rotate relative to each other;

[0009] A locking component is disposed between the first support portion and the second support portion;

[0010] The locking component has an unlocked state and a locked state. When the locking component is in the locked state, it is used to lock the relative positions of the first support part and the second support part, and the included angle between the first support part and the second support part is fixed at a preset angle.

[0011] In this embodiment, the angle between the first support and the second support is fixed by a locking component, eliminating the need for the first driving device to continuously operate and provide holding force. This reduces the power consumption of the first driving device, thereby improving the heat dissipation problem of the support device. Furthermore, the angle fixation is stable and reliable, improving the stability and reliability of the support device and enhancing the user experience.

[0012] In one possible implementation, the locking component is in an unlocked state, and the first support and the second support are able to rotate relative to each other.

[0013] In this embodiment of the disclosure, by switching the locking component to an unlocked state and a locked state, the angle between the first support part and the second support part can be adjusted and fixed, allowing the user to adjust the angle according to different usage scenarios, thereby increasing the flexibility of the support device and improving the user experience.

[0014] In one possible implementation, when the locking assembly is in a locked state and there is a rotational tendency between the first support portion and the second support portion in a first direction, the locking assembly is used to generate resistance in a second direction, the first direction being opposite to the second direction.

[0015] When the locking component is in the unlocked state, and the first support portion and the second support portion have a rotational tendency in the first direction, the resistance disappears.

[0016] In this embodiment of the present disclosure, by switching between the locked and unlocked states of the locking component, resistance in the opposite direction to the rotational trend between the first support and the second support is generated or eliminated, which can conveniently realize the angle adjustment and fixation between the first support and the second support, making the adjustment flexible and easy to control.

[0017] In one possible implementation, the locking assembly includes a first locking member and a second locking member. When the locking assembly is in a locked state, the first locking member and the second locking member are in contact with each other, and a frictional force is generated between the first locking member and the second locking member.

[0018] When the locking assembly is in the unlocked state, the first locking member and the second locking member are separated.

[0019] In this embodiment of the present disclosure, the locking assembly is configured as a first locking member and a second locking member that can move relative to each other, and the resistance is provided by the contact friction between the first locking member and the second locking member. There is no resistance when the first locking member and the second locking member are separated, which conveniently realizes the switching between the locking state and the unlocking state of the locking assembly. The structure is simple, easy to implement, and has high structural stability.

[0020] In one possible implementation, the support device further includes a second drive device, the output of which is connected to the locking assembly to drive the locking assembly to switch between the locked state and the unlocked state.

[0021] In this embodiment of the disclosure, by setting a second driving device to drive the locking component, the locking component can be controlled, eliminating the need for manual locking and unlocking, simplifying user operation and optimizing user experience.

[0022] In one possible implementation, the first locking member is fixedly connected to the first support portion, and the output end of the second driving device is connected to the second locking member via a transmission shaft;

[0023] When the locking assembly is in the locked state, the drive shaft extends toward the first locking member, the second locking member presses against the first locking member, and the first locking member and the second locking member are in contact with each other.

[0024] When the locking assembly is in the unlocked state, the drive shaft retracts in a direction away from the first locking member, and the second locking member separates from the first locking member.

[0025] In this embodiment of the present disclosure, the second driving device drives the second locking member through a transmission shaft. When the first locking member and the second locking member are in contact, they provide resistance. When the first locking member and the second locking member are separated, they do not provide resistance, thereby realizing the control of the locking assembly to adjust and fix the included angle between the first support and the second support.

[0026] In one possible implementation, the first locking member includes a first clutch plate, and the second locking member includes a second clutch plate.

[0027] In this embodiment of the present disclosure, frictional force can be generated and eliminated by means of a first clutch plate and a second clutch plate. The clutch plates are inexpensive, easy to purchase, and have a high coefficient of friction, stable frictional performance, and good wear resistance, making the locking and unlocking control of the locking structure more stable and reliable.

[0028] In one possible implementation, the locking assembly includes a damping portion disposed on a first surface of the first clutch plate and / or a second surface of the second clutch plate, the first surface being disposed opposite to the second surface.

[0029] In this embodiment of the present disclosure, the damping part is used to increase the roughness of the first surface and / or the second surface to increase the friction between the first clutch plate and the second clutch plate, thereby improving the locking reliability of the locking assembly.

[0030] In one possible implementation, the damping portion includes one or more of the following: rough particles, bumps, and stripes.

[0031] In this embodiment of the disclosure, the damping part can adopt a variety of combinations, and one or more of them can be selected to achieve the required friction force by designing the shape of the damping part.

[0032] In one possible implementation, the locking assembly includes a one-way transmission assembly, wherein when the one-way transmission assembly is driven along the first direction, the first support portion and the second support portion are able to rotate relative to each other;

[0033] When the unidirectional transmission assembly is subjected to an external force along the second direction, the relative positions of the first support and the second support are locked.

[0034] Wherein, the first direction is opposite to the second direction.

[0035] In this embodiment, the locking and unlocking of the locking component is achieved through a one-way transmission component. The structure is simple, the transmission is stable and controllable, which helps to improve the structural stability of the support equipment.

[0036] In one possible implementation, the second support portion is provided with a mounting portion for mounting the shooting device.

[0037] In this embodiment of the present disclosure, the shooting device is mounted on the second support part of the support device, which can support and stabilize the shooting device, prevent the shooting device from shaking during the shooting process, and thus improve the clarity of the captured image.

[0038] According to a second aspect of the present disclosure, a shooting system is provided, including a shooting device and a support device as described in the first aspect of the present disclosure, wherein the shooting device is fixed to a second support portion of the support device.

[0039] The shooting system of this embodiment is equipped with the above-mentioned support device. The support device fixes the included angle between the first support part and the second support part at a preset angle through a locking component, thereby fixing the shooting angle of the shooting device at the required angle to meet the user's shooting needs. At the same time, it does not require the continuous operation of the first driving device to achieve locking, reducing the power consumption of the first driving device, thereby reducing the overall power consumption of the shooting system, avoiding the heat generation problem caused by continuous operation, improving the reliability of the shooting system, and extending the service life of the shooting system.

[0040] According to a third aspect of the present disclosure, a vehicle is provided, including an on-board platform, the on-board platform being provided with support equipment as described in the first aspect of the present disclosure, or a shooting system as described in the second aspect of the present disclosure.

[0041] In this embodiment of the disclosure, the vehicle is equipped with the aforementioned support device or vehicle-mounted shooting system. The locking component fixes the included angle between the first support part and the second support part at a preset angle, which reduces power consumption while meeting the shooting requirements of different angles and avoids overheating caused by continuous operation of the drive device, thereby improving the user experience.

[0042] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0043] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

[0044] Figure 1 This is a schematic diagram of the structure of a support device in the locked state according to an exemplary embodiment.

[0045] Figure 2 This is a schematic diagram of the structure of a support device in the unlocked state according to an exemplary embodiment.

[0046] Figure 3 This is a schematic diagram of the structure of the first clutch plate according to an exemplary embodiment.

[0047] Figure 4 This is a schematic diagram of the structure of the second clutch plate according to an exemplary embodiment. Detailed Implementation

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0049] To improve shooting quality and meet the shooting needs from different angles, the shooting device can use a gimbal or other support equipment that can be adjusted in angle for support and stability.

[0050] In the supporting equipment of related technologies, since there is no separate locking structure, in order to keep the shooting device stable, the supporting equipment usually needs to continuously provide holding force through the driving device to achieve angle locking. That is, it needs to continuously supply power to the driving device. The driving device has high power consumption, resulting in obvious heat generation problems. The overall stability and reliability of the supporting equipment are also poor, and the user experience is not good.

[0051] To address the aforementioned technical problems, this disclosure provides a support device, a shooting system, and a vehicle. The support device uses a locking component to fix the angle between the first support part and the second support part, eliminating the need for a first driving device to continuously provide holding force, thus reducing the power consumption of the first driving device and improving the heat dissipation problem of the support device. Furthermore, the angle fixation is stable and reliable, improving the stability and reliability of the support device and enhancing the user experience.

[0052] According to an exemplary embodiment, such as Figures 1-4 As shown, this embodiment of the present disclosure provides a support device, which can be a gimbal and can be applied to various usage scenarios, such as vehicle-mounted gimbals, handheld gimbals, and outdoor gimbals. The support device includes a first support part 10, a second support part 20, and a first driving device 41. The first support part 10 and the second support part 20 are rotatably connected. The first driving device 41 is used to drive the first support part 10 and the second support part 20 to rotate relative to each other, so as to realize the angle adjustment of the support device.

[0053] The support device also includes a locking assembly 30. For example... Figure 1 As shown, the locking assembly 30 is disposed between the first support portion 10 and the second support portion 20. The first drive device 41 can have an operating state and a non-operating state. When the first drive device 41 is in the operating state, it provides power to drive the first support portion 10 and the second support portion 20 to rotate relative to each other. When the locking assembly 30 is in the locked state, it can be used to lock the relative position of the first support portion 10 and the second support portion 20, so that the included angle between the first support portion 10 and the second support portion 20 is fixed at a preset angle, without the need for the first drive device 41 to provide a holding force.

[0054] In this embodiment, the locking component 30 fixes the included angle between the first support portion 10 and the second support portion 20. The angle fixation is stable and reliable, and there is no need for the first driving device 41 to continuously provide holding force, which reduces the power consumption of the first driving device 41 and avoids the heat generation problem caused by continuous power supply to the first driving device 41. This improves the stability of the support device and extends the service life of the support device.

[0055] In some embodiments, the locking component 30 also has an unlocked state. For example... Figure 2 As shown, when the locking component 30 is in the unlocked state, the first driving device 41 can be in the working state, and the first support part 10 and the second support part 20 can be driven by the first driving device 41 to rotate relative to each other. By switching the locking component 30 to the unlocked state and the locked state, the angle between the first support part 10 and the second support part 20 can be adjusted or fixed, allowing users to adjust the angle according to different usage scenarios, increasing the flexibility of the support device and improving the user experience.

[0056] In some embodiments, when the locking component 30 is in the locked state, the first support portion 10 and the second support portion 20 have a rotational tendency in a first direction. The locking component 30 generates resistance in a second direction, which is opposite to the first direction, to prevent the relative movement tendency between the first support portion 10 and the second support portion 20, thus fixing their relative positions. When the locking component 30 is in the unlocked state, the first support portion 10 and the second support portion 20 have a rotational tendency in the first direction, the resistance disappears, and the first support portion 10 and the second support portion 20 can rotate relative to each other for angle adjustment. In the locked state, the locking component 30 generates resistance that prevents the relative movement tendency between the first support portion 10 and the second support portion 20. In the unlocked state, the resistance disappears. By switching between the locked and unlocked states of the locking component 30, resistance in the opposite direction to the rotational tendency between the first support portion 10 and the second support portion 20 is generated or eliminated. This allows for convenient angle adjustment and fixation between the first support portion 10 and the second support portion 20, providing flexible adjustment and easy control.

[0057] In some embodiments, such as Figures 1-2 As shown, the locking assembly 30 includes a first locking member 31 and a second locking member 32. Figure 1 As shown, when the locking assembly 30 is in the locked state, the first locking member 31 and the second locking member 32 are in contact with each other. The resistance includes the frictional force between the first locking member 31 and the second locking member 32. The frictional force generated by the contact connection between the first locking member 31 and the second locking member 32 prevents the relative movement tendency between the first support part 10 and the second support part 20, thereby achieving angle locking. Figure 2 As shown, when the locking assembly 30 is in the unlocked state, the first locking member 31 and the second locking member 32 are separated, the friction between them disappears, and there is no longer any resistance to the relative movement between the first support portion 10 and the second support portion 20. The first support portion 10 and the second support portion 20 can rotate relative to each other to achieve angle adjustment. By setting the locking assembly 30 to have a first locking member 31 and a second locking member 32 that can move relative to each other, and by using the contact friction between the first locking member 31 and the second locking member 32 to provide resistance, there is no resistance when the first locking member 31 and the second locking member 32 are separated. This conveniently realizes the switching between the locking state and the unlocked state of the locking assembly 30. The structure is simple, easy to implement, and has high structural stability.

[0058] In some embodiments, the first locking member 31 includes a first clutch plate, and the second locking member 32 includes a second clutch plate. The clutch plate is a structure that primarily functions through friction while also meeting structural performance requirements. Friction is generated by axial compression between the first and second clutch plates. When the first and second clutch plates separate, the friction disappears. The clutch plate is inexpensive, readily available, and possesses a high coefficient of friction, stable friction performance, and good wear resistance, making the locking and unlocking control of the locking assembly 30 more stable and reliable.

[0059] In some embodiments, the first clutch plate and the second clutch plate can be configured in various shapes. The first clutch plate and the second clutch plate can be circular, square, irregularly shaped, etc., and their shapes and sizes can be the same or different. For example, to improve the engagement effect between the first clutch plate and the second clutch plate, they can be configured as circles of equal size. Of course, those skilled in the art can also configure the first clutch plate and the second clutch plate in other shapes; the embodiments of this disclosure do not impose excessive limitations on the shape and size of the first clutch plate and the second clutch plate.

[0060] In some embodiments, such as Figures 1-4 As shown, the locking assembly 30 includes a damping portion 33. The damping portion 33 can be disposed on the first surface 311 of the first clutch plate (i.e., the first locking member 31) and / or the second surface 321 of the second clutch plate (i.e., the second locking member 32). The damping portion 33 is used to increase the roughness of the first surface 311 and / or the second surface 321 to increase the friction between the first clutch plate and the second clutch plate, thereby improving the locking reliability of the locking assembly 30. The first surface 311 and the second surface 321 are disposed opposite to each other, that is, the first clutch plate and the second clutch plate are stacked. The first surface 311 is the surface of the first clutch plate closest to the second clutch plate, and the second surface 321 is the surface of the second clutch plate closest to the first clutch plate. In one example, as... Figure 3 As shown, the first surface 311 of the first clutch plate is provided with a damping portion 33. In another example, as... Figure 4 As shown, the second surface 321 of the second clutch plate is provided with a damping portion 33. In yet another example, as... Figures 3-4 As shown, both the first surface 311 of the first clutch plate and the second surface 321 of the second clutch plate are provided with damping portions 33.

[0061] In some embodiments, the damping portion 33 includes one or more of the following: coarse particles, bumps, and stripes. In one example, such as... Figure 3As shown, the damping portion 33 is configured as coarse particles. In another example, the damping portion 33 of the first surface 311 is configured as bumps, and the damping portion 33 of the second surface 321 is configured as stripes. In yet another embodiment, as... Figure 4 As shown, the damping part 33 includes rough particles and stripes. The damping part 33 can be in various combinations, and one or more of them can be selected to achieve the required frictional force by designing the shape of the damping part 33.

[0062] Of course, it is understandable that when damping portions 33 are provided on both the first surface 311 of the first clutch plate and the second surface 321 of the second clutch plate, the shapes of the damping portions 33 can be the same or different, as long as they can improve the surface roughness and thus increase friction. This disclosure does not impose too many restrictions on this.

[0063] In some embodiments, the support device further includes a second drive unit 42. For example... Figures 1-2 As shown, the output terminal of the second drive device 42 is connected to the locking assembly 30 to drive the locking assembly 30 in... Figure 1 The locked state shown is the same as Figure 2 The system switches between the shown unlocked states. By setting the second drive device 42 to drive the locking component 30, the locking component 30 can be controlled, eliminating the need for manual locking and unlocking, simplifying user operation, and optimizing the user experience.

[0064] In one example, such as Figures 1-2 As shown, the first locking member 31 is fixedly connected to the first support portion 10. The output end of the second driving device 42 is connected to the second locking member 32 via a transmission shaft 421. The transmission shaft 421 can drive the second locking member 32 to move, causing the second locking member 32 to move closer to or further away from the first locking member 31. The second driving device 42 drives the second locking member 32 via the transmission shaft 421. The contact friction between the first locking member 31 and the second locking member 32 provides resistance. There is no resistance when the first locking member 31 and the second locking member 32 are separated, thereby realizing the control of the locking assembly 30 to adjust and fix the included angle between the first support portion 10 and the second support portion 20.

[0065] When the locking component 30 is in the locked state, such as Figure 1 As shown, the drive shaft 421 extends toward the first locking member 31 (that is... Figure 1(As shown in the horizontal leftward direction), the second locking member 32 is driven by the transmission shaft 421. The second locking member 32 presses against the first locking member 31 so that the first locking member 31 and the second locking member 32 come into contact and connect. Friction is generated between the first locking member 31 and the second locking member 32, which hinders the relative movement tendency between the first support part 10 and the second support part 20, thereby realizing the angle locking between the first support part 10 and the second support part 20.

[0066] When the locking component 30 is in the unlocked state, such as Figure 2 As shown, the drive shaft 421 retracts in a direction away from the first locking member 31 (i.e., Figure 2 (As shown in the horizontal rightward direction), the second locking member 32 and the first locking member 31 separate, the friction between them disappears, the first support part 10 and the second support part 20 are no longer subject to resistance, and they can rotate relative to each other to achieve angle adjustment.

[0067] In some embodiments, the second drive device 42 includes a VCM (Voice Coil Motor). VCM motors are called voice coil motors because their principle is similar to that of a loudspeaker. A VCM typically operates within a permanent magnetic field, controlling the stretching position of a spring plate by changing the magnitude of the DC current in the motor's coil, thereby driving up and down movement. It features high frequency response and high precision, and is widely used in applications where space is limited and high-precision control is required.

[0068] Of course, it is understood that the second drive device 42 can also be other types of drive devices such as servo motors and variable frequency motors. In addition, the type of the first drive device 41 can be the same as or different from the second drive device 42. This embodiment of the present disclosure does not impose any special restrictions on the specific types of the first drive device 41 and the second drive device 42.

[0069] In some embodiments, the first drive device 41 is connected to one of the first support portion 10 and the second support portion 20, and the output end of the first drive device 41 is connected to the other of the first support portion 10 and the second support portion 20, so as to drive the first support portion 10 and the second support portion 20 to rotate relative to each other through the first drive device 41.

[0070] In one example, such as Figures 1-2 As shown, the first drive device 41 is fixedly connected to the second support part 20. The output end of the first drive device 41 is connected to the first support part 10 through the rotating shaft 411. The first locking member 31, the second locking member 32 and the second drive device 42 all have hollow installation spaces 60 so that the rotating shaft 411 can pass through the installation space 60 and connect to the first support part 10.

[0071] In some embodiments, the locking assembly 30 includes a one-way transmission assembly (not shown in the figure). The one-way transmission assembly can be, for example, a one-way gear, a one-way bearing, or other transmission mechanism. When the one-way transmission assembly moves along a first direction, the first support portion 10 and the second support portion 20 can rotate relative to each other. When the one-way transmission assembly is subjected to an external force along a second direction, the one-way transmission assembly self-locks, locking the relative positions of the first support portion 10 and the second support portion 20. The first direction is opposite to the second direction. Locking and unlocking the locking assembly 30 through the one-way transmission assembly is simple in structure, provides stable and controllable transmission, and helps improve the structural stability of the support equipment.

[0072] In some embodiments, the second support portion 20 is provided with a mounting portion (not shown in the figure) for mounting the shooting device 50. The shooting device 50 can be an electronic device such as a mobile terminal, camera, or tablet computer that is detachably mounted on the second support portion 20, or it can be a camera or other component with shooting function that is fixed to the mounting portion of the second support portion 20. This embodiment does not impose too many limitations on this. The support device can serve as a support accessory for the shooting device 50, or the support device and the shooting device 50 can be combined into a whole shooting device with a support and stabilization function. By mounting the shooting device 50 through the second support portion 20 of the support device, the shooting device 50 can be supported and stabilized, preventing the shooting device 50 from shaking during the shooting process, thereby improving the clarity of the captured image.

[0073] According to an exemplary embodiment, such as Figures 1-4 As shown, this disclosure provides a shooting system, which includes a shooting device 50 and a supporting device as described in the above embodiments.

[0074] The support device includes a first support portion 10, a second support portion 20, and a first driving device 41. The first support portion 10 and the second support portion 20 are rotatably connected. The first driving device 41 drives the first support portion 10 and the second support portion 20 to rotate relative to each other. The support device also includes a locking assembly 30, which is disposed between the first support portion 10 and the second support portion 20. When the first driving device 41 is not in operation, the locking assembly 30 is in a locked state, and the locking assembly 30 is used to lock the relative position of the first support portion 10 and the second support portion 20, fixing the included angle between the first support portion 10 and the second support portion 20 at a preset angle. The shooting device 50 is fixed to the second support portion 20 of the support device, and the support device and the shooting device 50 together constitute a shooting system.

[0075] In the shooting system of this embodiment, since the supporting device fixes the included angle between the first supporting part 10 and the second supporting part 20 at a preset angle through the locking component 30, the shooting angle of the shooting device 50 can be fixed at the required angle to meet the user's shooting needs. At the same time, it is not necessary to continuously run the first driving device 41 to achieve locking, which reduces the power consumption of the first driving device 41, thereby reducing the overall power consumption of the shooting system, avoiding the heat generation problem caused by continuous operation, improving the reliability of the shooting system, and extending the service life of the shooting system.

[0076] According to an exemplary embodiment, such as Figures 1-4 As shown in the figure, this disclosure provides a vehicle (not shown), which includes an on-board platform. The on-board platform is equipped with the support equipment or shooting system described in the above embodiments. That is, the support equipment in this disclosure can be an on-board gimbal, and the shooting system can be an on-board shooting system.

[0077] In this embodiment of the disclosure, the vehicle is equipped with the aforementioned support device or vehicle-mounted shooting system. The locking component fixes the included angle between the first support part and the second support part at a preset angle, which reduces power consumption while meeting the shooting requirements of different angles and avoids overheating caused by continuous operation of the drive device, thereby improving the user experience.

[0078] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.
