Description
Technical Field
[0001] This utility model relates to the technical field of gimbals, and more specifically, to a gimbal motor lock and a gimbal that is directly connected to a mobile phone. Background Technology
[0002] A gimbal motor consists of a rotor and a stator. The stator is composed of multiple coil windings that generate a rotating magnetic field when energized. The rotor is composed of multiple permanent magnet plates and rotates under the drive of the stator's magnetic field. When the motor is not in use, a motor lock is used to lock the rotor relative to the stator in a specific position to prevent rotation due to external forces or accidents. A common locking method is as follows: a mating port is provided on the rotor housing, and a locking structure is provided on the stator housing. When locked, the locking structure engages with the mating port on the rotor housing; when unlocked, the locking structure disengages from the mating port on the stator housing, thus unlocking the motor.
[0003] In existing technologies, a locking mechanism often uses a locking pin and a keyhole. Locking is achieved by manually pushing the locking pin into the keyhole, and unlocking is achieved by manually pushing the locking pin out of the keyhole. This locking structure has several drawbacks. First, it involves numerous components in the gimbal locking mechanism, occupying a large space and hindering miniaturization. Second, the manual operation of switching between locking and unlocking states can lead to misjudgment of the locking / unlocking direction, potentially damaging the locking structure.
[0004] In addition, direct-connection mobile phone gimbals are much smaller than ordinary handheld gimbals. Furthermore, direct-connection mobile phone gimbals have higher requirements for ease of operation compared to ordinary handheld gimbals. That is, direct-connection mobile phone gimbals place increasingly higher demands on the miniaturization of motors and motor locks, as well as ease of operation. The motor locks and motors commonly used in existing technologies are difficult to meet the needs of direct-connection mobile phone gimbals. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a gimbal motor lock and a gimbal that is directly connected to a mobile phone. The structure is simple, occupies little space, and can meet the requirements of miniaturization design and convenient operation.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A gimbal motor lock is provided, including a first limiting part disposed on the stator, a second limiting part disposed on the rotor, and a locking assembly movably connected to the rotor. A limiting groove is formed between the second limiting part and the locking assembly. When the rotor rotates relative to the stator until the first limiting part engages with the limiting groove, it switches to a locked state. When the rotor rotates relative to the stator until the first limiting part bypasses the locking assembly and disengages from the limiting groove, it switches to an unlocked state.
[0008] This utility model discloses a gimbal motor lock. A first limiting part and a second limiting part abut against each other to restrict the rotor's rotation relative to the stator in a first direction. The first limiting part abuts against the locking assembly to restrict the rotor's rotation relative to the stator in a second direction. The first and second directions are clockwise and counterclockwise, respectively. When the rotor rotates relative to the stator until the first limiting part engages with the limiting groove, it switches to a locked state. Because the locking assembly is movably connected to the rotor, the torque generated by the motor rotation compresses the locking assembly, causing it to move and allowing the first limiting part to pass over the locking assembly and disengage from the limiting groove, thus completing the unlocking process. This utility model's gimbal motor lock comprises only three components: a first limiting part, a second limiting part, and a locking assembly. It has fewer structural parts, a simpler structure, and occupies less space, meeting the requirements for miniaturization and convenient operation. Furthermore, this utility model uses motor torque to drive the gimbal motor to switch between the unlocked and locked states, avoiding the risk of damage to the locking structure due to misjudgment of the locking and unlocking directions that can occur with manual switching.
[0009] Furthermore, the first limiting part is a limiting block facing away from the motor axis, and the second limiting part is a limiting protrusion facing the motor axis. The upper and lower surfaces of the limiting block and the limiting protrusion are flush. The stator part where the first limiting part is located is inside the rotor part where the second limiting part is located. When the second limiting part and the locking assembly rotate with the rotor, the first limiting part can be engaged into the limiting groove or disengaged from the limiting groove.
[0010] Furthermore, a first transition surface is formed between the second limiting part and the inner circumferential surface of the rotor, and the first transition surface and a portion of the surface of the locking assembly form the groove wall of the limiting groove. The first transition surface guides the movement of the first limiting part, making its movement more stable.
[0011] Furthermore, the locking assembly includes a locking member and a driving member for moving the locking member between a locked position and an unlocked position, the driving member being connected between the rotor and the locking member. When the locking member is in the locked position, the first limiting part engages in the limiting groove, thereby achieving locking; when the locking member is in the unlocked position, the first limiting part, when rotating relative to the second limiting part and the locking assembly, can bypass the locking assembly and disengage from the limiting groove, thereby achieving unlocking.
[0012] Furthermore, the rotor has a rotor end cap at its end, and the locking member is radially telescopically connected to the rotor, while the locking member is radially slidably connected to the rotor end cap. This slidable connection between the locking member and the end cap facilitates stable movement of the locking member, allowing for stable switching between the locked and unlocked positions.
[0013] Furthermore, the locking element is a push lock, the driving element is a spring, the rotor has a first mounting groove, and the locking element has a second mounting groove opposite to the first mounting groove. The two free ends of the spring are respectively connected to the groove walls of the first and second mounting grooves. When the spring is in the reset state and the first limiting part is engaged in the limiting groove, one side of the first limiting part abuts against the second limiting part, and the other side of the first limiting part abuts against the stop surface of the locking assembly, thereby achieving locking. When unlocking is required, the first limiting part compresses the locking element with the movement of the motor, and the locking element compresses the spring. The spring compression causes the locking element to move away from the motor shaft in the radial direction of the motor, allowing the first limiting part to smoothly pass over the locking element.
[0014] Furthermore, the locking element is a push rod, and the driving element includes a first magnetic element disposed on the rotor and a second magnetic element disposed on the push rod. When the first magnetic element and the second magnetic element attract each other, the system switches to the unlocked state; when the first magnetic element and the second magnetic element repel each other, the system switches to the locked state. The position of the push rod is changed by the attraction or repulsion between the first magnetic element and the second magnetic element, thereby causing the push rod position to move between the unlocked position and the locked position.
[0015] Furthermore, it also includes a reset component disposed between the rotor and the locking component. The locking component is a push rod. The driving component includes a first magnetic component disposed on the rotor and a second magnetic component disposed on the push rod. When the first magnetic component and the second magnetic component attract each other, it switches to the unlocked state; under the action of the reset component, it switches to the locked state. In addition to using only the repulsive force between the first magnetic component and the second magnetic component for reset, a reset component such as a spring can also be used for reset.
[0016] Furthermore, the locking member is provided with a third limiting part, and the rotor or the rotor end cover is provided with a fourth limiting part. When switched to the unlocked state, the third limiting part and the fourth limiting part abut against each other to limit the position. The locking member is provided with a fifth limiting part, and the rotor end cover is provided with a sixth limiting part. When switched to the locked state, the fifth limiting part and the sixth limiting part abut against each other to limit the position. The abutment of the third and fourth limiting parts limits the unlocked position, and the abutment of the fifth and sixth limiting parts limits the locked position, which can effectively improve the stability of use.
[0017] This utility model also provides a gimbal that is directly connected to a mobile phone, including at least one motor equipped with a gimbal motor lock as described above.
[0018] This utility model relates to a gimbal that directly connects to a mobile phone. The mobile phone serves as the handle of the gimbal, and the mobile phone screen can be used as a monitor for synchronized and real-time viewing. It is small in size, compact in structure, easy to carry, and low in cost. Furthermore, the use of the above-mentioned gimbal motor lock can meet the requirements of miniaturization and convenient operation of gimbals that directly connect to mobile phones.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] The gimbal motor lock of this utility model has fewer structural parts, a simple structure, and occupies less space, which can meet the requirements of miniaturization design and convenient operation. Moreover, the gimbal motor lock of this utility model uses motor torque to drive the gimbal motor to switch between the unlocked and locked states, avoiding the risk of damage to the locking structure due to misjudgment of the locking and unlocking direction that occurs when manually driving the switching between the locking and unlocking states.

[0036] Example 1
[0037] like Figures 1 to 3The first embodiment of the gimbal motor lock 100 of this utility model is shown, including a first limiting part 110 disposed on the stator 200, a second limiting part 120 disposed on the rotor 300, and a locking assembly 130 movably connected to the rotor 300. A limiting groove 140 is formed between the second limiting part 120 and the locking assembly 130. When the rotor 300 rotates relative to the stator 200 until the first limiting part 110 engages with the limiting groove 140, it switches to the locked state. When the rotor 300 rotates relative to the stator 200 until the first limiting part 110 passes around the locking assembly 130 and disengages from the limiting groove 140, it switches to the unlocked state. Figure 1 , Figure 4-5 As shown.
[0038] The first limiting part 110 is a limiting block facing away from the motor axis, and the second limiting part 120 is a limiting protrusion facing the motor axis. The upper and lower surfaces of the limiting block and the limiting protrusion are flush. The stator 200 portion containing the first limiting part 110 is located inside the rotor 300 portion containing the second limiting part 120. When the second limiting part 120 and the locking assembly 130 rotate with the rotor 300, the first limiting part 110 can engage with or disengage from the limiting groove 140. Figure 1 , Figure 4 As shown. In order to enable the first limiting part 110 to better act on the locking component 130, in this embodiment, the upper surface of the locking component 130 can be set higher than the upper surfaces of the first limiting part 110 and the second limiting part 120, and the lower surface of the locking component 130 can be lower than the lower surfaces of the first limiting part 110 and the second limiting part 120, thereby maximizing the contact area between the first limiting part 110 and the locking component 130.
[0039] A first transition surface 150 is formed between the second limiting part 120 and the inner peripheral surface of the rotor 300. The first transition surface 150 and a portion of the surface of the locking assembly 130 form the groove wall of the limiting groove 140. Figure 4 As shown. The first transition surface 150 guides the movement of the first limiting part 110, making its movement more stable. Specifically, in this embodiment, the first transition surface 150 can be a smooth arc surface, allowing the first limiting part 110 to smoothly enter or exit the limiting groove 140. To facilitate processing, this embodiment provides a second transition surface 160 on the opposite side of the first transition surface 150, with the first transition surface 150 and the second transition surface 160 symmetrical to both sides of the second limiting part 120. The first transition surface 150 and the second transition surface 160 not only facilitate processing but also effectively prevent stress concentration.
[0040] The locking assembly 130 includes a locking member 131 and a driving member 132 for moving the locking member 131 between a locked position and an unlocked position. The driving member 132 is connected between the rotor 300 and the locking member 131. When the locking member 131 is in the locked position, the first limiting part 110 engages with the limiting groove 140, thereby achieving locking. When the locking member 131 is in the unlocked position, the first limiting part 110 can rotate relative to the second limiting part 120 and the locking assembly 130, thereby bypassing the locking assembly 130 and disengaging from the limiting groove 140, thereby achieving unlocking. In this embodiment, the driving member 132 is a unidirectional driving member that can drive the locking member 131 from the locked position to the unlocked position or from the unlocked position to the locked position, while the movement in the other direction is driven by the reset member. The driving member 132 can also be a bidirectional driving member 132 that can drive the locking member 131 from the locked position to the unlocked position and from the unlocked position to the locked position.
[0041] The rotor 300 has a rotor end cap 400 at its end. A locking member 131 is radially telescopically connected to the rotor 300, and radially slidably connected to the rotor end cap 400. This slidable connection allows the locking member 131 to move stably, enabling stable switching between locked and unlocked positions. Specifically, in this embodiment, a groove 410 is provided on the end cap. This groove 410 is not a through groove, but an open groove with one closed end, thus providing stable sliding while maintaining an aesthetically pleasing appearance.
[0042] In this embodiment, a first positioning structure and a second positioning structure with a concave-convex fit can be respectively provided on the opposite peripheral surfaces of the rotor 300 and the locking member 131. When the locking member 131 is in the unlocked position, the first positioning structure and the second positioning structure cooperate to position it.
[0043] The specific working principle of this embodiment is as follows:
[0044] The first limiting part 110 and the second limiting part 120 abut against each other to restrict the rotor 300 from rotating relative to the stator 200 in a first direction. The first limiting part 110 abuts against the locking component 130 to restrict the rotor 300 from rotating relative to the stator 200 in a second direction. The first direction and the second direction are clockwise and counterclockwise, respectively. When the rotor 300 rotates relative to the stator 200 to the point where the first limiting part 110 engages with the limiting groove 140, one side of the first limiting part 110 abuts against the second limiting part 120, and the other side of the first limiting part 110 abuts against the stop surface of the locking component 130. The gimbal 500 motor switches to the locked state. Since the locking component 130 is movably connected to the rotor 300, the motor rotates, and the stator 200 and the rotor 300 rotate relative to each other. The locking component 130 is squeezed or driven to move, allowing the first limiting part 110 to pass over the locking component 130 and disengage from the limiting groove 140. At this time, the unlocking is completed. The gimbal motor lock 100 in this embodiment includes only three components: the first limiting part 110, the second limiting part 120, and the locking component 130. It has fewer structural parts, a simpler structure, and occupies less space, which can meet the requirements of miniaturization design and convenient operation. Moreover, this utility model uses motor torque to drive the gimbal 500 motor to switch between the unlocked and locked states, avoiding the risk of damage to the locking structure due to misjudgment of the locking and unlocking directions that occurs when manually driving the switching between the locking and unlocking states.
[0045] Example 2
[0046] This embodiment is the second embodiment of the gimbal motor lock 100 of this utility model. This embodiment is similar to the first embodiment, except that a push lock is used as the locking element 131 and a spring is used as the driving element 132. Figure 2-3 As shown.
[0047] Specifically, the rotor 300 has a first mounting groove 310, and the push lock has a second mounting groove 133 opposite to the first mounting groove 310. The two free ends of the spring are connected to the groove walls of the first mounting groove 310 and the second mounting groove 133, respectively. The first mounting groove 310 and the second mounting groove 133 together form a receiving groove for the spring, which can guide the extension and contraction of the spring. When the spring is in the reset state and the first limiting part 110 is engaged in the limiting groove 140, one side of the first limiting part 110 abuts against the second limiting part 120, and the other side of the first limiting part 110 abuts against the stop surface of the locking assembly 130, thereby achieving locking. When unlocking is required, the first limiting part 110 compresses the push lock with the movement of the motor, and the push lock compresses the spring. The spring compression causes the push lock to move away from the motor shaft in the radial direction of the motor, and the first limiting part 110 can smoothly pass over the push lock, thereby achieving the switch from the locked state to the unlocked state. In this embodiment, the push lock is an F-structure, including a first crossbar, a second crossbar, and a vertical bar perpendicular to the first and second crossbars. The first crossbar slides at least partially within the slide groove 410.
[0048] The push lock is provided with a third limiting part 134, and the rotor 300 or rotor end cover 400 is provided with a fourth limiting part 320. When switched to the unlocked state, the third limiting part 134 and the fourth limiting part 320 abut and limit the movement. Specifically, in this embodiment, the positioning step at the corner of the second horizontal bar and the vertical bar can be used as the third limiting part 134, and the fourth limiting part 320 can be a positioning step provided on the rotor 300. The two positioning steps cooperate to limit the movement; or the end of the first horizontal bar can be used as the third limiting part 134, and the groove wall of the sliding groove 410 on the rotor end cover 400 can be used as the fourth limiting part 320. The third limiting part 134 and the fourth limiting part 320 abut and limit the movement. Of course, this utility model can also have the above two limiting forms at the same time, with multiple abutments to jointly achieve the limiting.
[0049] The push lock is provided with a fifth limiting part 135, and the rotor end cover 400 is provided with a sixth limiting part 420. When switched to the locked state, the fifth limiting part 135 and the sixth limiting part 420 abut and limit each other. The third limiting part 134 and the fourth limiting part 320 abut and limit the unlocked position, and the fifth limiting part 135 and the sixth limiting part 420 abut and limit the locked position, which can effectively improve the stability of use. Specifically, in this embodiment, the other end of the first crossbar can be used as the fifth limiting part 135, and the other groove wall of the slide groove 410 on the rotor end cover 400 can be used as the sixth limiting part 420. The fifth limiting part 135 and the sixth limiting part 420 abut against each other to achieve limiting. The cross section of the slide groove 410 is an elongated hole with semicircular ends. The cross sections of the first crossbar, the second crossbar, and the vertical bar are all cylindrical. When the first crossbar slides to the two ends of the slide groove 410, the first crossbar just fits against the two semicircular side walls of the two slide grooves 410.
[0050] The specific working principle of this embodiment is similar to that of Embodiment 1, except that:
[0051] When the spring is in the reset state and the first limiting part 110 is engaged in the limiting groove 140, one side of the first limiting part 110 abuts against the second limiting part 120 and the other side of the first limiting part 110 abuts against the stop surface of the locking assembly 130 to achieve locking. When unlocking is required, the first limiting part 110 presses the push lock with the movement of the motor, the push lock presses the spring, and the spring compression causes the push lock to move away from the motor shaft in the radial direction of the motor. The first limiting part 110 can smoothly pass over the push lock to achieve the switch from the locked state to the unlocked state.
[0052] Example 3
[0053] This embodiment is the third embodiment of the gimbal motor lock 100 of this utility model. This embodiment is similar to Embodiment 1 or Embodiment 2, except that the locking element 131 is a push rod, and the driving element 132 includes a first magnetic element 330 disposed on the rotor 300 and a second magnetic element disposed on the push rod. When the first magnetic element 330 and the second magnetic element attract each other, the system switches to the unlocked state; when the first magnetic element 330 and the second magnetic element repel each other, the system switches to the locked state. The position of the push rod is changed by the attraction or repulsion between the first magnetic element 330 and the second magnetic element, thereby causing the push rod position to move between the unlocked position and the locked position. Figure 6-7 As shown.
[0054] Specifically, in this embodiment, the first magnetic component 330 and the second magnetic component can be specifically configured as electromagnets. By changing the direction of the current in the electromagnet, the direction of the electromagnet's magnetic poles is changed, thereby changing the direction of the force between the first magnetic component 330 and the second magnetic component. The push rod can be configured as a T-shape rotated 90° clockwise, and the second magnetic component can be specifically configured on the crossbar of the push rod. The first magnetic component 330 is a U-shape rotated 90° clockwise, and the crossbar of the push rod slides within the U-shaped opening. In addition, in this embodiment, a first positioning structure and a second positioning structure with concave-convex cooperation can be provided on the opposing peripheral surfaces of the push rod and the first magnetic component 330. When the push rod is in the unlocked position, the first positioning structure and the second positioning structure cooperate to position it.
[0055] The specific working principle of this embodiment is similar to that of Embodiment 2, except that:
[0056] When the first magnetic component 330 attracts the second magnetic component, the system switches to the unlocked state; when the first magnetic component 330 repels the second magnetic component, the system switches to the locked state. The position of the push rod is changed by the attraction or repulsion between the first and second magnetic components, allowing the push rod to move between the unlocked and locked positions. This embodiment utilizes the change in the force between the first and second magnetic components to switch between the unlocked and locked positions. It can actively release the limiting effect of the limiting groove 140 on the first limiting part 110, allowing the first limiting part 110 to smoothly pass over the locking component 130 and switch to the unlocked state.
[0057] Example 4
[0058] This embodiment is the fourth embodiment of the gimbal motor lock 100 of this utility model. This embodiment is similar to embodiment three, except that it also includes a reset component disposed between the rotor 300 and the push rod. The locking component 131 is the push rod, and the driving component 132 includes a first magnetic component 330 disposed on the rotor 300 and a second magnetic component disposed on the push rod. When the first magnetic component 330 and the second magnetic component attract each other, the system switches to the unlocked state; under the action of the reset component, it switches to the locked state. Besides using only the repulsive force between the first magnetic component 330 and the second magnetic component for reset, a spring or other reset component can also be used. In this embodiment, the first magnetic component 330 and the second magnetic component can be either an electromagnet or a permanent magnet, or both can be electromagnets.
[0059] In this embodiment, the reset element can be a spring disposed between the rotor 300 and the push rod. When the first magnetic element 330 is energized, it attracts the push rod and compresses the spring. After the power is turned off, the spring resets and pushes the push rod toward the motor shaft. Alternatively, the reset element can be a reset magnet disposed on the rotor 300 on the side of the push rod opposite to the second magnetic element. The attraction of the reset magnet is less than the attraction of the electromagnet when it is energized. Therefore, after the electromagnet is de-energized, the reset magnet attracts the push rod to move toward the motor shaft.
[0060] The specific working principle of this embodiment is similar to that of Embodiment 3, except that:
[0061] When the first magnetic component 330 and the second magnetic component attract each other, they provide a force for the push rod to move radially along the rotor 300. For example, when unlocking, the electromagnet is energized and generates an attractive force that pulls the push rod away from the motor shaft, thus switching to the unlocked state. When locking, the electromagnet is de-energized, and the reset component provides a force for the push rod to move towards the motor shaft, so that a groove is formed between the push rod and the limit protrusion, i.e., the locked position, so as to lock the limit block in the groove.
[0062] Example 5
[0063] This embodiment is an example of a gimbal 500 directly connected to a mobile phone, including at least one motor equipped with a gimbal motor lock 100 as in any of the embodiments one to four. The gimbal 500 can be a three-axis gimbal 500, a two-axis gimbal 500, or a single-axis gimbal 500, as shown in the figures.
[0064] In this embodiment, the gimbal 500 may have a built-in battery 510, and the connection with the mobile phone is mainly used for data communication, such as... Figure 9 As shown; at this time, the battery 510 is designed as a square structure set at the bottom of the gimbal 500, thus forming a "7" shaped structure at the bottom of the gimbal 500. Its two inner sides are in close contact with the two adjacent sides of the mobile phone, which can help stabilize the connection between the mobile phone and the gimbal 500.
[0065] In this embodiment, the gimbal 500 can also be powered without a battery 510, via a mobile phone. In this case, the connection between the gimbal 500 and the mobile phone is used for both data communication and power supply. The connection between the mobile phone and the gimbal 500 can be a wired connection or a wireless connection via Wi-Fi, Bluetooth, or other wireless transmission methods. Figure 8 As shown; if data communication is established between the mobile phone and the gimbal 500, the gimbal 500 can be driven through the mobile phone interface, and the recordings from the gimbal 500 can be stored on the mobile phone for real-time viewing; among them, such as Figure 11 As shown, the mobile phone and the gimbal 500 are connected via a wired connection.
[0066] For the connection and fixation between the gimbal 500 and the mobile phone, a mounting platform 520 is provided at the bottom of the gimbal 500, and the battery 510 is located at the bottom of the mounting platform 520. In this embodiment, the following fixing methods are used, but not limited to:
[0067] The mounting platform 520 connects directly to the phone's USB-C port. This connection method enables both the structural connection between the phone and the gimbal 500 and the communication connection between them, making operation convenient and quick. This mounting method, combined with the contact friction between the battery 510 and the side of the phone, results in a compact structure and good stability.
[0068] Clamping blocks 530 are respectively provided on both sides of the mounting platform 520. The clamping blocks 530 are telescopically or rotatably connected to the mounting platform 520, and an elastic element that generates clamping force is provided between the clamping blocks 530 and the mounting platform 520. In this way, the gimbal 500 can be stably clamped to the mobile phone by clamping the two clamping blocks 530 to the two opposite sides of the mobile phone. Figure 10 As shown.
[0069] The two fixing methods mentioned above can be set individually or simultaneously. Combining the two fixing methods can achieve a stable PTZ 500 structure, which can effectively improve the user experience.
[0070] The gimbal 500 of this utility model directly connects to a mobile phone. The mobile phone serves as the handle of the gimbal 500, and the mobile phone screen can be used as a monitor for synchronized and real-time viewing of the screen. It is small in size, compact in structure, easy to carry, and low in cost. Furthermore, the use of the gimbal motor lock 100 can meet the miniaturization design requirements and convenient operation requirements of the gimbal 500 directly connected to the mobile phone.
