Description

Technical Field

[0001] This invention belongs to the field of stabilizer technology, and particularly relates to a gimbal and stabilizer. Background Technology

[0002] A gimbal serves as a support platform for mobile devices with cameras, such as smartphones. It stabilizes and supports the device, controls its movement and shooting, thus providing a stable shooting environment. Gimbals are typically compatible with multiple brands and models of mobile devices.

[0003] Currently, gimbals on the market do not have radar for auxiliary distance measurement, which makes it easy for mobile devices to collide with objects around the gimbal or the gimbal itself during rotation. At the same time, the 360-degree rotation of the cantilever can easily cause the phone on the cantilever to hit the gimbal itself. Summary of the Invention

[0004] The main objective of this invention is to propose a gimbal and stabilizer that aims to solve the technical problem that mobile devices on the gimbal are prone to collisions during rotation in the prior art.

[0005] To achieve the above objectives, the present invention provides a gimbal comprising: a cantilever assembly for clamping a mobile device, the cantilever assembly having a cantilever hollow cavity; a protective shell having a base cavity; a drive mechanism including a drive component and a drive shaft, the drive component being installed in the base cavity, one end of the drive shaft being located in the cantilever hollow cavity and connected to the cantilever assembly, and the other end being drively connected to the drive component, the drive component being used to drive the drive shaft to rotate, causing the drive shaft to drive the cantilever assembly to rotate relative to the protective shell; and a radar module installed in the cantilever hollow cavity, the radar module being used for ranging and communicating with a control motherboard.

[0006] In this embodiment of the invention, the driving member is used to drive the driving shaft to rotate clockwise and counterclockwise. The driving shaft is provided with a limiting protrusion. The protective shell is provided with a rotation blocking step with a first blocking groove and a second blocking groove. The first blocking groove is used to limit the clockwise rotating limiting protrusion to a first position, and the second blocking groove is used to limit the counterclockwise rotating limiting protrusion to a second position, so that the cantilever assembly can reciprocate between the first position and the second position relative to the protective shell.

[0007] In this embodiment of the invention, the protective shell is provided with a movable groove, which is used to cooperate with the limiting protrusion guide, and the rotating blocking step is provided at the end of the movable groove.

[0008] In this embodiment of the invention, the gimbal further includes a flexible buffer ring sleeved outside the drive shaft. The inner circumference of the flexible buffer ring abuts against the drive shaft, and the outer circumference is in frictional rotational engagement with the protective shell. The flexible buffer ring is used to dampen and buffer the cantilever assembly through the drive shaft.

[0009] In this embodiment of the invention, the driving component is provided with a driving gear, the driving shaft is provided with a driven gear that meshes with the driving gear, the driving shaft is fitted with a rotary bearing, and the driven gear is provided with rotary bearings on both sides along the axial direction of the driving shaft. The outer ring of the rotary bearing is interference-fitted with the protective shell, and the inner ring of the protective shell is interference-fitted with the driving shaft.

[0010] In this embodiment of the invention, there are two rotary bearings, namely a large bearing and a small bearing. The small bearing is located close to the driving component, and the large bearing is located close to the cantilever assembly. The flexible buffer ring is located between the large bearing and the small bearing along the axial direction of the driving shaft.

[0011] In this embodiment of the invention, the radar module includes: a radar motherboard, installed in the hollow cavity of the cantilever; and a radar line, wherein the drive shaft is provided with a hollow wire passage for the radar line to pass through, one end of the radar line is located in the hollow cavity of the cantilever and connected to the radar motherboard, and the other end passes through the hollow wire passage and is used to connect to the control motherboard.

[0012] In this embodiment of the invention, the driving member is provided with a clearance groove on the side facing the hollow wire passage to avoid the radar line, so that the radar line can bend around the driving member. The gimbal also includes a wire protection sleeve disposed at the bend of the radar line, and the wire protection sleeve is confined within the hollow wire passage.

[0013] In an embodiment of the invention, the cantilever assembly includes a first cantilever and a second cantilever. The first cantilever includes a front cover plate and a first side plate, the front cover plate being connected to the drive shaft. The second cantilever covers the first cantilever and together with the first cantilever forms a hollow cavity in the cantilever. The second cantilever includes a rear cover plate and a second side plate. The rear cover plate is provided with a clearance hole for the drive shaft to pass through. The front cover plate and the rear cover plate are arranged opposite to each other along the axial direction of the drive shaft. And / or, the drive shaft passes through the protective shell through the outlet of the base cavity. The protective shell is provided with a limiting groove for a limiting spring, the limiting groove being located near the outlet. The spring is sleeved on the drive shaft and abuts against the protective shell along the axial direction of the drive shaft.

[0014] The present invention also proposes a stabilizer comprising a support frame and a gimbal as described above, the support frame being connected to the base and used to support the gimbal.

[0015] Through the above technical solutions, the gimbal provided in the embodiments of the present invention has the following beneficial effects: A radar module installed on the cantilever assembly enables auxiliary ranging for the gimbal. As the drive mechanism rotates the cantilever assembly relative to the protective shell, the radar module swings along with the cantilever assembly. The radar mainboard measures distances to obstacles around the cantilever assembly and transmits this distance information to the control mainboard via radar lines. The control mainboard determines if there is a collision risk with the mobile device held by the cantilever assembly. If a collision risk exists, the control mainboard shuts down the drive mechanism and issues a collision alarm, thus preventing a collision through the radar module's auxiliary ranging. The protective shell protects the drive mechanism's drive components and drive shaft, preventing interference from other components and ensuring smooth drive of the cantilever assembly. This guarantees the stable operation of the cantilever assembly, drive mechanism, and radar module. The gimbal in this invention, by adding a radar module for auxiliary ranging, avoids collisions between the gimbal and the mobile device during rotation. Furthermore, the protective shell protects the drive components and drive shaft from interference from external components, ensuring stable operation of the gimbal during rotation.

[0018] Explanation of reference numerals in the attached figures Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] The gimbal according to the present invention is described below with reference to the accompanying drawings.

[0021] like Figures 1 to 8 As shown, in an embodiment of the present invention, the gimbal 100 includes a cantilever assembly 1, a protective shell 2, a drive mechanism, and a radar module 5. The cantilever assembly 1 is used to clamp the mobile device and has a cantilever hollow cavity 11. The protective shell 2 has a base cavity 21. The drive mechanism includes a drive component 3 and a drive shaft 4. The drive component 3 is installed in the base cavity 21. One end of the drive shaft 4 is located in the cantilever hollow cavity 11 and connected to the cantilever assembly 1, and the other end is connected to the drive component 3. The drive component 3 is used to drive the drive shaft 4 to rotate, so that the drive shaft 4 drives the cantilever assembly 1 to rotate relative to the protective shell 2. The radar module 5 is installed in the cantilever hollow cavity 11 and is used for ranging and communicating with the control motherboard.

[0022] It should be noted that the gimbal 100 in this embodiment is mainly used as a stabilizer. The specific product type of mobile device to which the gimbal 100 and stabilizer can be applied is not limited, such as mobile phones, tablets, cameras, camcorders, and other types of portable shooting devices. The number, specific type, location, and arrangement of the cameras included in the mobile device are also not limited. For example, the mobile device can be a quad-camera phone, with four cameras arranged in a row on the back of the phone. The lenses of the four cameras are an ultra-wide-angle lens, a zoom lens, a viewfinder lens, and a depth-of-field assist lens, respectively. A radar window 12 is provided on the cantilever assembly 1 corresponding to the radar module 5. The radar module 5 can emit detection signals to the outside of the hollow cavity 11 of the cantilever through the radar window 12 to detect whether there are obstacles near the radar window 12.

[0023] A radar module 5 is installed on the cantilever assembly 1 to assist the gimbal 100 in ranging. During the rotation of the cantilever assembly 1 relative to the protective shell 2 driven by the drive mechanism, the radar module 5 swings along with the cantilever assembly 1. The radar mainboard 51 can measure the distance to obstacles around the cantilever assembly 1 and send the ranging information to the control mainboard via radar line 52. The control mainboard can determine whether there is a collision risk to the mobile device held by the cantilever assembly 1. If a collision risk exists, the control mainboard can shut down the drive component 3 and issue a collision alarm, thus avoiding a collision through the auxiliary ranging of the radar module 5. The protective shell 2 protects part of the structure of the drive component 3 and drive shaft 4 of the drive mechanism, preventing interference from other components and ensuring smooth driving of the cantilever assembly 1 by the drive shaft 4. This ensures the stable operation of the cantilever assembly 1, the drive mechanism, and the radar module 5. In this embodiment, the gimbal 100 is equipped with a radar module 5 for auxiliary ranging, which can prevent the gimbal 100 and the mobile device from colliding during rotation. At the same time, the protective shell 2 can protect the drive component 3 and drive shaft 4, preventing the drive mechanism from being interfered with by external components, and ensuring the smooth operation of the gimbal 100 during rotation.

[0024] It should be noted that the drive component 3 is used to drive the drive shaft 4 to rotate clockwise and counterclockwise. The drive shaft 4 is provided with a limiting protrusion 46. The protective shell 2 is provided with a rotation blocking step 22 having a first blocking groove 221 and a second blocking groove 222. The first blocking groove 221 is used to limit the clockwise rotating limiting protrusion 46 to a first position, and the second blocking groove 222 is used to limit the counterclockwise rotating limiting protrusion 46 to a second position, so that the cantilever assembly 1 can reciprocate between the first position and the second position relative to the protective shell 2.

[0025] like Figure 8 As shown, Figure 8 The cantilever assembly 1 in the first row of gimbals 100 is in the initial position, the cantilever assembly 1 in the second row of gimbals 100 is in the first position, and the cantilever assembly 1 in the third row of gimbals 100 is in the second position. The initial position of the cantilever assembly 1 can be vertical. The radar line 52 passes through the hollow drive shaft 4. The limiting protrusion 46 is directly above the drive shaft 4. The rotation blocking step 22 is set below the drive shaft 4. The first position of the cantilever assembly 1 can be a position rotated 140 degrees clockwise from the vertical position. The second position of the cantilever assembly 1 can be a position rotated 140 degrees counterclockwise from the vertical position. This allows the cantilever assembly 1 to rotate 140 degrees clockwise and counterclockwise respectively, enabling it to perform reciprocating rotational motions clockwise and counterclockwise during operation. This satisfies the shooting requirements while preventing the mobile device and the cantilever assembly 1 from colliding with other structures on the gimbal 100.

[0026] In this embodiment, the limiting protrusion 46 can be a rivet post. The protective shell 2 adds a rotating blocking step 22. When the limiting protrusion 46 rotates 140 degrees clockwise or counterclockwise, it will hit the first blocking groove 221 and the second blocking groove 222 of the rotating blocking step 22 respectively, so that the cantilever assembly 1 can no longer rotate. In this embodiment, the limiting protrusion 46 and the rotating blocking step 22 can achieve 140 degrees of rotation clockwise and counterclockwise, which not only meets the rotation requirements for shooting, but also avoids the mobile device from hitting the gimbal 100 itself. At the same time, the cantilever can only move back and forth, avoiding the situation where the cantilever assembly 1 rotates 360 degrees too much and twists and breaks the radar line 52, thus ensuring that the radar line 52 will not be twisted off.

[0027] In one embodiment, the protective shell 2 is provided with a movable groove 23, which is used to guide and cooperate with the limiting protrusion 46. A rotation blocking step 22 is provided at the end of the movable groove 23. In this embodiment, the movable groove 23 has an arc, and the rotation blocking step 22 is provided at the bottom of the movable groove 23. When the driving member 3 drives the driving shaft 4 and drives the cantilever assembly 1 to rotate relative to the protective shell 2, the limiting protrusion 46 on the driving shaft 4 guides and cooperates with the movable groove 23 during the rotation, so that the rotation trajectory of the driving shaft 4 is stable. When rotating to the first position or the second position, the rotation blocking step 22 provided at the bottom of the movable groove 23 can limit the limiting protrusion 46, avoiding the cantilever assembly 1 from over-rotating. The mechanical structure enables the cantilever assembly 1 to reciprocate, avoiding the situation where the cantilever assembly 1 rotates more than 360 degrees and twists and breaks the radar line 52, thus ensuring that the radar line 52 will not be twisted off.

[0028] like Figures 3 to 5 As shown, the gimbal 100 also includes a flexible buffer ring 6 sleeved on the drive shaft 4. The inner circumference of the flexible buffer ring 6 abuts against the drive shaft 4, and the outer circumference is in frictional rotational engagement with the protective shell 2. The flexible buffer ring 6 is used to dampen the cantilever assembly 1 through the drive shaft 4. A buffer limiting groove 45 for limiting the flexible buffer ring 6 can be provided on the outer side of the drive shaft 4. Part of the flexible buffer ring 6 protrudes from the buffer limiting groove 45. The flexible buffer ring 6 can be an O-ring rubber ring. The addition of a rubber ring between the drive shaft 4 and the protective shell 2 achieves a damping buffering effect, which can prevent the cantilever assembly 1 or the drive shaft 4 from shaking when the drive component 3 stops suddenly. The outer circumference of the flexible buffer ring 6 is in frictional rotational engagement with the protective shell 2, and the drive component 3 drives the drive shaft 4, which in turn provides power for the rotation of the cantilever assembly 1. In this embodiment, the rubber ring is fixed in the buffer limiting groove 45 and rotates in friction with the protective shell 2. The rubber ring achieves a damping effect between the large gear and the protective shell 2, preventing the cantilever from shaking when the motor stops suddenly.

[0029] In this embodiment of the invention, the driving component 3 is provided with a driving gear 31, and the driving shaft 4 is provided with a driven gear 42 that meshes with the driving gear 31. A rotary bearing 7 is sleeved on the driving shaft 4, and rotary bearings 7 are provided on both sides of the driven gear 42 along the axial direction of the driving shaft 4. The outer ring of the rotary bearing 7 is interference-fitted with the protective shell 2, and the inner ring of the protective shell 2 is interference-fitted with the driving shaft 4. In this embodiment, the driving component 3 is a geared motor that provides power to the entire assembly. The motor can be fixed to the protective shell 2 by multiple screws. The driving gear 31 can be a small gear, the driven gear 42 can be a large gear, and the driving shaft 4 is a hollow shaft with gears, such as... Figure 5 As shown, the driven gear 42 is positioned above the driving gear 31, and the drive shaft 4 extends in the front-to-back direction, making the drive mechanism compact. Rotary bearings 7 can be provided on both the front and rear sides of the driven gear 42. These bearings can fix the drive shaft 4 and the protective housing 2 relatively, while also ensuring that the drive shaft 4 can rotate smoothly relative to the protective housing 2.

[0030] The large gear can be made of stainless steel and is hollow to allow for wiring. The large gear rotates in conjunction with the small gear on the motor, thereby driving the drive shaft 4 to rotate relative to the protective shell 2. The limiting protrusion 46 can be set on the rear end face of the driven gear 42. During the rotation of the driven gear 42, the limiting protrusion 46 on the driven gear 42 cooperates with the protective shell 2 to limit the rotation angle.

[0031] like Figure 6 and Figure 7As shown, there are two rotary bearings 7, namely a large bearing 7a and a small bearing 7b. The small bearing 7b is located near the drive component 3, and the large bearing 7a is located near the cantilever assembly 1. The flexible buffer ring 6 is located between the large bearing 7a and the small bearing 7b along the axial direction of the drive shaft 4. In one embodiment, a large bearing 7a is provided at the front end of the rotary bearing 7, and a small bearing 7b is provided at the rear end. The cross-sectional dimension of the large bearing 7a is larger than that of the small bearing 7b. By assembling the front and rear ends of the drive shaft 4 with rotary bearings 7 of different cross-sectional dimensions, the assembly stability of the drive shaft 4 can be ensured, while also improving the structural compactness of the gimbal 100. Furthermore, the protective shell 2 can be provided with a first riveting groove 24 with a stepped cross-section for limiting the large bearing 7a, and a second riveting groove 25 with a stepped cross-section for limiting the small bearing 7b. The drive shaft 4 has corresponding first riveting grooves 24 and second riveting grooves 25. 5 is respectively provided with a third riveting groove 43 and a fourth riveting groove 44, which respectively limit the large bearing 7a and the small bearing 7b. The cross-section of the third riveting groove 43 and the fourth riveting groove 44 is stepped, so that the outer ring of the large bearing 7a is riveted to the protective shell 2 with an interference fit, and the inner ring of the large bearing 7a is riveted to the drive shaft 4 with an interference fit; the outer ring of the small bearing 7b is riveted to the protective shell 2 with an interference fit, and the inner ring of the small bearing 7b is riveted to the large gear with an interference fit, thereby improving the assembly stability between the protective shell 2, the drive shaft 4 and the rotary bearing 7.

[0032] In one embodiment, the radar module 5 includes a radar mainboard 51 and a radar line 52. The radar mainboard 51 is installed inside the hollow cavity 11 of the cantilever. The drive shaft 4 is provided with a hollow wire passage 41 for the radar line 52 to pass through. One end of the radar line 52 is located inside the hollow cavity 11 of the cantilever and connected to the radar mainboard 51, while the other end passes through the hollow wire passage 41 and is used to connect to the control mainboard. The radar module 5 installed on the cantilever assembly 1 enables auxiliary ranging of the gimbal 100. During the rotation of the cantilever assembly 1 relative to the protective shell 2 driven by the drive mechanism, the radar module 5 can swing together with the cantilever assembly 1. The radar mainboard 51 can measure the distance to obstacles around the cantilever assembly 1 and send the ranging information to the control mainboard through the radar line 52. The control mainboard can determine whether there is a collision risk to the mobile device held by the cantilever assembly 1. If there is a collision risk, the control mainboard can shut down the drive component 3 and issue a collision alarm, thus avoiding collision through the auxiliary ranging of the radar module 5. The protective shell 2 protects the drive components 3 and drive shaft 4 of the drive mechanism, preventing interference from other components. The hollow drive shaft 4 allows the radar wire 52 of the radar module 5 to connect to the control motherboard via the hollow wire passage 41. This allows the drive shaft 4 to drive the cantilever assembly 1 while simultaneously protecting the radar wire 52, preventing it from becoming entangled with other components and affecting the rotation of the cantilever assembly 1. It also prevents other components from cutting the radar wire 52, ensuring stable operation of the cantilever assembly 1, the drive mechanism, and the radar module 5. In this embodiment, the gimbal 100 uses the radar module 5 for auxiliary ranging, preventing collisions between the gimbal 100 and the mobile device during rotation. The protective shell 2 also protects the drive components 3 and drive shaft 4, preventing interference from external components. The hollow drive shaft 4 not only transmits power but also protects the radar wire 52, ensuring smooth operation of the gimbal 100 during rotation.

[0033] like Figure 4 and Figure 5 As shown, the drive component 3 has a clearance groove 32 on the side facing the hollow cable passage 41 to avoid the radar line 52, allowing the radar line 52 to bend and bypass the drive component 3. The gimbal 100 also includes a protective sleeve 8 at the bend of the radar line 52, which is confined within the hollow cable passage 41. In this embodiment, a protective sleeve 8 is added at the bend of the radar line 52. The rubber material of the protective sleeve 8 is used to protect the radar line 52, ensuring that the radar line 52 does not rub against the rubber protective sleeve 8 and thus does not damage the radar line 52. It also prevents the radar line 52 from being cut by the drive shaft 4. Furthermore, the top of the drive component 3 has a clearance groove 32, providing sufficient space 10 between the drive component 3 and the protective shell 2 to prevent the radar line 52 from being jammed by the protective shell 2 or the drive component 3 during the rotation of the cantilever assembly 1. Figure 4 As shown, the bottom of the clearance groove 32 is arc-shaped, which ensures that the radar line 52 will not be cut by the groove wall of the clearance groove 32.

[0034] like Figure 4 As shown, the cantilever assembly 1 includes a first cantilever 13 and a second cantilever 14. The first cantilever 13 includes a front cover plate 131 and a first side plate 132. The front cover plate 131 is connected to the drive shaft 4. The second cantilever 14 covers the first cantilever 13 and together with the first cantilever 13 forms a cantilever cavity 11. The second cantilever 14 includes a rear cover plate 141 and a second side plate 143. The rear cover plate 141 is provided with a clearance hole 142 for the drive shaft 4 to pass through. The front cover plate 131 and the rear cover plate 141 are arranged opposite each other along the axial direction of the drive shaft 4.

[0035] Understandably, countersunk screws can be used to fix the first cantilever 13 and the second cantilever 14, and countersunk screws can be used to fix the first cantilever 13 to the large gear; the first cantilever 13 can be made of aluminum alloy and can fix the radar module 5 and connect the mobile device; the second cantilever 14 can be made of aluminum alloy and can protect and cover the radar module 5; the radar module 5 can include a radar lens 53 set in the radar window 12. The radar lens 53 can be made of glass. The radar lens 53 can transmit radar laser while protecting the radar module 5. The radar module 5, fixed to the first cantilever 13, can realize the ranging function; the radar module 5 can be fixed to the first cantilever 13 with screws; the radar module 5 is fixed to the first cantilever 13 and rotates with the first cantilever 13. The limiting protrusion 46 is fixed to the large gear and rotates with the large gear to realize clockwise and counterclockwise rotation.

[0036] In this embodiment, the first side plate 132 and the second side plate 143 are both L-shaped plates. The front cover plate 131 and the rear cover plate 141 both extend in the left and right direction, so that the first cantilever 13 and the second cantilever 14 are both Z-shaped. The first cantilever 13 and the second cantilever 14 cooperate with each other and cover each other, which can ensure the structural stability of the cantilever assembly 1. The radar window 12 can be opened in the left and right direction on the side of the first side plate 132 away from the second side plate 143, and the radar window 12 is located below the front cover plate 131, which can avoid the drive shaft 4 while ensuring the structural compactness of the cantilever assembly 1. Furthermore, the drive shaft 4 passes through the outlet of the base cavity 21 and passes through the protective shell 2. The protective shell 2 is provided with a limiting groove 26 for the limiting spring 9. The limiting groove 26 is located near the outlet. The spring 9 is sleeved on the outside of the drive shaft 4 and abuts against the protective shell 2 along the axial direction of the drive shaft 4. In this embodiment, the retaining ring 9 can be an elastic component, capable of elastic deformation to fix the large gear inside the protective housing 2. The protective housing 2 can be made of aluminum alloy. In this embodiment, the cross-sectional dimension of the retaining ring 9 is larger than that of the large bearing 7a, which can prevent the drive shaft 4 from detaching from the protective housing 2 through the outlet.

[0037] In one embodiment, the assembly sequence of the gimbal 100 may be as follows: First, the flexible buffer ring 6 is placed inside the buffer limiting groove 45 of the drive shaft 4. The inner diameter of the flexible buffer ring 6 is smaller than the diameter of the buffer limiting groove 45, so that the flexible buffer ring 6 is tightly attached to the drive shaft 4. Then, the large bearing 7a is fixed to the front end of the drive shaft 4 by press riveting, so that the inner ring of the large bearing 7a is fixed together with the drive shaft 4. Then, the large bearing 7a is pressed and riveted into the protective shell 2. The outer ring of the large bearing 7a is stopped in the first riveting groove 24 of the protective shell 2. At the same time, the outer ring of the large bearing 7a is pressed and riveted together with the inner wall of the protective shell 2 through an interference fit, so that the outer ring of the large bearing 7a is fixed together with the protective shell 2. Insert the snap ring 9 into the limiting groove 26 of the protective shell 2 to prevent the drive shaft 4 from coming out of the protective shell 2; The small bearing 7b at the rear end is fixed to the drive shaft 4 by press riveting. The inner ring of the small bearing 7b is fixed to the drive shaft 4 by press riveting, and the outer ring of the small bearing 7b is fixed to the protective shell 2 by press riveting. Thus, the drive shaft 4 is connected to the protective shell 2 through two rotary bearings 7, and the drive shaft 4 and the protective shell 2 can rotate relative to each other through the two rotary bearings 7. First, put the protective sleeve 8 on the radar wire 52, and then pass the radar wire 52 through the hollow wire passage 41 of the drive shaft 4. Then, the radar lens 53 and the radar motherboard 51 are fixed to the first cantilever 13, and then the radar wire 52 is first inserted into the radar motherboard 51. Then fix the first cantilever 13 to the drive shaft 4; Then the second cantilever 14 is fixed to the first cantilever 13 to shield and protect the radar module 5. Finally, the drive component 3 can be fixed to the protective shell 2; The radar line 52 of the radar module 5 is connected to the control motherboard through the hollow drive shaft 4 and the cable protection sleeve 8, thereby realizing the auxiliary ranging of the radar module 5, and the hollow cable routing does not damage the cable.
