Embodiment 2

This embodiment is based on the first embodiment. Referring to FIG. 1 to FIG. 3, the driving member 30 may include a driving end 31 and a escaping portion 32. The driving end 31 is for abutting against the latching portion 12, and the escaping portion 32 is for accommodating the latching portion 12.

In the unlocked state, the catching portion 12 and the relief portion 32 are always aligned, and the driving end 31 relieves the latching portion 12. When the driving member 30 slides relative to the first body 10, the latching portion 12 can be detached from the escaping portion 32 and enter the mating portion 21 under the abutment of the driving end 31 to switch to the locked state.

It should be noted that the “unlocked state” described in this embodiment may refer to all states except the locked state, specifically including the state of the first body 10 and the second body 20 before relative installation, that is, preparation The state before the installation, such as the state of the second body 20 in FIG. 1 before being assembled to the first body 10; and the momentary unlocked state after the first body 10 and the second body 20 are switched to the unlocked state in the locked state. Of course, in other embodiments, the "unlocked state" corresponds to the "locked state", and there is an intermediate state between the "unlocked state" and the "locked state".

It can be understood that in this embodiment, the latching portion 12 and the relief portion 32 are always aligned. "Alignment" does not mean that the latching portion 12 matches the shape of the relief portion 32, but only refers to the positional correspondence.

More preferably, the relief portion 32 can be an annular groove, and the fitting portion 21 can also be an annular groove, thereby even the first body 10 The fitting position with the second body 20 is not determined in the circumferential direction, and the catching portion 12 can also be aligned with the relief portion 32 or the fitting portion 21.

Embodiment 3

The embodiment is based on the second embodiment. Further, an axial elastic member 50 may be disposed between the first body 10 and the driving member 30. The axial elastic member 50 is used to make the driving member relative to the card in the unlocked state. The holding portion 12 is axially positioned. It should be noted that since the first body 10 and the second body 20 are respectively a propeller and a motor, the axial direction in this embodiment refers to the direction of the central axis of rotation of the first body 10 and the second body 20. The axial elastic member 50 may be a cylindrical spring, a rubber block or other elastic device, and is not particularly limited in this embodiment.

Specifically, the first body 10 may include a mounting protrusion 111 for mounting the second body 20 to be inserted. The mounting convex portion 111 may have a cylindrical shape, and a through hole may be formed in the cylindrical wall of the cylindrical mounting convex portion, and the through hole forms an accommodating space for the holding portion 12 to be accommodated.

The mounting protrusion 111 may be integrally molded with the first body 10. Specifically, a mounting hole for mounting the mounting protrusion 111 may be formed in the first body 10. A guide passage 1111 for sliding the driving member 30 may be formed between the outer side wall of the mounting boss 111 and the inner wall of the mounting hole of the first body 10. The driving member 30 may be a columnar body, and a boss portion 33 having a larger cross section than the upper portion may be formed at a lower portion of the columnar body. The outer side surface of the boss portion 33 is engaged with the side wall of the guide passage 1111, and the relief portion 32 is formed on the inner side surface of the boss portion 33. The boss portion 33 at the bottom end of the relief portion 32 forms the above-described drive end 31.

A positioning flange 1112 is formed on the first body 10 and at an end of the mounting hole facing away from the mounting boss 111. A gap is also formed between the outer outer side of the driving member 30 and the hole wall of the mounting hole, and the axial elastic member 50 may be disposed in the gap and between the positioning flange 1112 and the boss portion 33 of the driving member 30.

Of course, the shape of the axial elastic member 50, the shape of the driving member 30, and the shape of the first body 10 are only preferred embodiments, and the present invention is not limited to the above embodiments, and those skilled in the art may Other similar structures that can implement the corresponding functions are designed, and the invention is not limited.

In this embodiment, the driving member 30 is pressed at a preset position by using the axial elastic member 50. In particular, the driving member 30 can be pressed at the position where the avoiding portion 32 and the holding portion 12 are aligned in the unlocked state. Keeping the position of the driving member 30 from swaying, such that when the second body 20 is assembled to the first body 10, and before the mating portion 21 of the second body 20 is aligned with the engaging portion 12 of the first body 10, The relief portion 32 can always be aligned with the catch portion 12 such that the catch portion 12 can be reliably held by the second body 20 into the escape portion 32 before switching to the locked state.

Embodiment 4

The embodiment is based on any of the above embodiments, and further, the locking device may further include a return elastic member 40. The return elastic member 40 is for driving the driving member 30 to slide relative to the first body 10 to effect switching from the unlocked state to the locked state. The reset elastic member 40 may specifically be a component that can store elastic potential energy under an external force, and may be, for example, a spring, a rubber, or the like. The driving member 30 is slidable relative to the first body 10 by the action of the return elastic member 40.

In the present embodiment, the return elastic member 40 may be disposed between the driving member 30 and the second body 20. In the unlocked state, the return elastic member 40 can be gradually compressed by the second body 20 until the second body 20 moves until the mating portion 21 is aligned with the catch portion 12, and the return elastic member 40 triggers the movement of the drive member 30. Specifically, before the second body 20 is mounted to the first body 10, the return elastic member 40 may be in a natural extension state or in a compressed state, and in the process of mounting the second body 20 to the first body 10, resetting The elastic member 40 can be continuously compressed or further compressed by the second body 20, and the return elastic member 40 can be disposed away from the second body 20 when the elastic potential energy stored by the elastic member 40 due to compression reaches a preset value. The direction releases the elastic potential energy, thereby driving the driving member 30 to move against the holding portion 12, so that the locking portion 12 enters the fitting portion 21 to achieve the locking between the first body 10 and the second body 20.

Of course, those skilled in the art can understand that the return elastic member 40 can be fixedly coupled with the driving member 30, or the reset elastic member 40 can be pressed only between the driving member 30 and the second body 20. Of course, when the return elastic member 40 is fixedly coupled to the driving member 30, the return elastic member 40 is not easily detached from the driving member 30, and the structure is more stable.

In particular, based on the third embodiment, before the second body 20 is mounted on the first body 10, the relief portion 32 on the driving member 30 is aligned with the latch portion 12 on the first body 10, and the reset elastic member 40 can be at In the naturally extended state or the compressed state, when the second body 20 is mounted to the first body 10, the second body 20 abuts against the return elastic member 40, and the return elastic member 40 is continuously compressed by the second body 20, when The elastic potential energy stored in the reset elastic member 40 is greater than the sum of the gravitational potential energy of the driving member and the elastic potential energy of the axial elastic member. At this time, the return elastic member 40 is elongated in a direction away from the second body 20, thereby driving the driving member 30. Moving, the driving end 31 of the driving member 30 abuts the latching portion 12, so that the latching portion 12 enters the mating portion 21 to achieve locking between the first body 10 and the second body 20, in this state, the axial direction The elastic member 50 is further compressed.

Of course, it should be noted that when the embodiment is based on the second embodiment, the reset elastic member 40 can only release the self-elastic potential energy against the gravitational potential energy of the driving member 30 to drive the driving member 30 to move.

In addition, please continue to refer to FIG. 1 to FIG. 3, the state shown in FIG. 1 is a locked state, in which the driving end 31 abuts the latching portion 12, and when the first body 10 and the second body are needed When the disassembly 20 is disassembled, the driving member 30 can be pressed in the mounting direction away from the second body 20, and the driving member 30 is moved to the escaping portion 32 to be aligned with the urging portion 12, and the axial elastic member 50 is in the previous locked state. When the operator presses the driving member 30, once the avoiding portion 32 is aligned with the holding portion 12, the first body 10 and the second body 20 are relatively detachable, and the elastic restoring force of the elastic member 50 in the axial direction is utilized. The axial elastic member 50 can automatically drive the first body 10 to be reversely popped in a direction away from the second body 20, thereby further reducing the operation difficulty of the operator when disassembling the first body 10 and the second body 20. More time and effort.

Embodiment 5

The embodiment is further optimized based on the fourth embodiment, and the reset elastic member 40 may include a compression elastic member 401 and an abutting member 402 disposed at a lower end of the compression elastic member 401. The abutting member 402 is for compressing the compression elastic member 401 under the abutting action of the second body 20. The abutting member 402 can form a larger contact area with the second body 20, so that the second body 20 can better transmit the abutting force to the compression elastic member 401, so that the entire return elastic member 40 Can be compressed more smoothly.

In this embodiment, especially when the compression elastic member 401 is a spring, the contact between the abutting member 402 and the second body 20 is more balanced than the spring directly contacting the second body 20, and the force of the return elastic member 40 is more balanced. The compression is more stable.

Embodiment 6

The embodiment is based on the first embodiment. Further, referring to FIG. 4 to FIG. 6 to the first body 10, the first body 10 may include a mounting protrusion 111, and the periphery of the mounting protrusion 111 is used for arranging the second body 20; the mating portion 21 may be The second body 20 is disposed on an inner side surface of the mounting convex portion 111. Specifically, an annular groove may be formed on the inner side surface of the second body 20, the annular groove forms the engaging portion 21, and after the second body 20 is mounted on the first body 10, the position of the engaging portion 21 and the holding portion The positions of 12 are aligned so that the catch portion 12 can be directly laterally snapped into the mating portion 21.

Example 7

The embodiment is based on the sixth embodiment. Further, the shape of the mounting protrusion 111 may be cylindrical in the shape of the sixth embodiment, and the driving member 30 may be slidably disposed in the inner cavity of the mounting protrusion 111. A through hole is formed in the mounting convex portion 111 along the thickness direction of the cylindrical wall, and the holding portion 12 is disposed in the through hole. Preferably, the inner cavity of the cylindrical mounting protrusion 111 can form a passage for the driving member 30 to slide, and at least part of the outer side wall of the driving member 30 can cooperate with the inner tube wall of the mounting protrusion 111 to guide the inner tube wall. Sliding in a predetermined direction, the structure is relatively simple and the performance is reliable.

Example eight

On the basis of the seventh embodiment, the driving member 30 may include a guiding portion 301 and a connecting portion 302 formed at the top of the guiding portion 301. The outer side of the guide section 301 can be engaged with the inner cavity of the mounting boss 111. A relief portion 32 is provided on the outer side surface of the guide segment 301, and the relief portion 32 can accommodate the latch portion 12. Specifically, the outer side surface of the guiding section 301 can cooperate with the inner side wall of the inner cavity of the mounting convex portion 111, and the driving member 30 is linearly moved under the guidance of the inner side wall of the mounting convex portion 111.

Before the second body 20 is mounted on the first body 10, the second body 20 cannot be mounted on the first body 10 due to the need to prevent the blocking of the latching portion 12, and therefore, before the second body 20 is mounted, the card is held. The portion 12 cannot protrude from the outer side surface of the first body 10. At this time, the operator can operate the driving member 30 such that the relief portion 32 of the driving member 30 is aligned with the holding portion 12 to provide a escaping space for the holding portion 12. The second body 20 can be set to the outside of the first body 10, and the second body 20 is set After being mounted on the first body 10, the position of the driving member 30 is adjusted, so that the driving member 30 can abut the holding portion 12, and the holding portion 12 enters into the engaging portion 21 on the second body 20, and the holding portion 12 Engagement with the mating portion 21, thereby ensuring reliable locking between the first body 10 and the second body 20.

The connecting section 302 can protrude from the mounting boss 111 to provide an operating position for operator operation. Specifically, the operator can drive the sliding of the driving member 30 by operating the connecting section 302.

Further, a driving end 31 connected to the relief portion 32 may be formed on the outer side surface of the guiding section 301. The driving end 31 is for abutting the catching portion 12 to enter a locked state. The driving end 31 can be directly formed by the outer side wall of the guiding section 301, and the entire guiding section 301 can have a cylindrical shape, and the relief portion 32 is opened on the cylindrical side wall. The relief portion 32 can be an annular groove. The driving end 31 may be formed at a position other than the escaping portion 32 on the guiding portion 301. For example, the upper end guiding portion of the escaping portion 32 and the lower end guiding portion of the escaping portion 32 may each form a driving end 31, specifically by the driving member 30. The direction of motion is determined. For example, if the driving member 30 needs to be moved up during the switching from the unlocked state to the locked state, the lower end guiding section of the relief portion 32 forms the driving end 31. Preferably, the driving end 31 and the latching portion 12 can be in point contact to minimize the friction between the latching portion 12 and the driving end 31, so that the operation is smoother. Of course, if the latching portion 12 and the driving end are not considered The contact between the driving end 31 and the holding portion 12 may not be a point contact, such as a surface contact or a line contact, which is not limited in this embodiment.

The portion 12 is axially positioned. It should be noted that since the hub and the motor are respectively a propeller and a motor, the axial direction in this embodiment refers to the direction of the hub and the central axis of rotation of the motor. The axial elastic member 50 may be a cylindrical spring, a rubber block or other elastic device, and is not particularly limited in this embodiment.

Specifically, the hub may include a mounting boss 111 for the power supply to be installed. Mounting projection Specifically, the cylinder 111 may have a cylindrical shape, and a through hole may be formed in the cylindrical wall of the cylindrical mounting protrusion, and the through hole forms an accommodating space for the holding portion 12 to be accommodated.

In particular, the driving member 30 can be pressed at the position where the avoiding portion 32 and the holding portion 12 are aligned in the unlocked state. The position of the driving member 30 is kept from swaying, so that the escaping portion 32 can always be with the accommodating portion 12 during the assembly of the motor to the hub, and before the mating portion 21 of the motor is aligned with the catch portion 12 of the hub. The alignment is such that the catch portion 12 can be reliably held by the motor into the relief portion 32 before switching to the locked state.

Example twenty two

The embodiment is based on any one of the nineteenth embodiment to the twenty-first embodiment. Further, the driving member 30 may further be provided with a reset elastic member 40. The return spring 40 is used to drive the drive member 30 to slide relative to the hub to effect switching from the unlocked state to the locked state. The reset elastic member 40 may specifically be a component that can store elastic potential energy under an external force, and may be, for example, a spring, a rubber, or the like. The drive member 30 is slidable relative to the hub by the return resilient member 40.

In the present embodiment, the return elastic member 40 may be disposed between the driving member 30 and the motor. In the unlocked state, the return elastic member 40 can be gradually compressed by the motor until the motor moves to the alignment portion 21 in alignment with the catch portion 12, and the return elastic member 40 triggers the movement of the drive member 30. Specifically, the return elastic member 40 may be in a natural extension state or in a compressed state before the motor is mounted to the hub. When the motor is mounted to the hub, the return elastic member 40 can be continuously compressed or further compressed by the motor, and the elastic member is reset when the elastic energy stored by the return elastic member 40 due to compression reaches a preset value. The elastic potential energy can be released in a direction away from the motor, thereby driving the driving member 30 to move against the latching portion 12, so that the latching portion 12 enters the mating portion 21 to achieve locking between the hub and the motor.

Of course, those skilled in the art can understand that the return elastic member 40 can be fixedly coupled with the driving member 30, or the reset elastic member 40 can be pressed only between the driving member 30 and the motor. Of course, when the return elastic member 40 is fixedly coupled to the driving member 30, the return elastic member 40 is not easily detached from the driving member 30, and the structure is more stable.

In particular, based on the twenty-first embodiment, before the motor is mounted on the hub, the relief portion 32 on the driver member 30 is aligned with the catch portion 12 on the hub, and the return resilient member 40 can be in a naturally elongated state or In the compressed state, when the motor is mounted to the hub, the motor abuts the return elastic member 40, and the return elastic member 40 is continuously compressed by the motor, and the elastic potential energy stored in the reset elastic member 40 is greater than the gravitational potential energy of the driving member. The sum of the elastic potentials of the axial elastic members, at this time, the return elastic member 40 is elongated in a direction away from the motor, thereby driving the driving member 30 to move, so that the driving end 31 of the driving member 30 abuts the holding portion 12, so that the card The holding portion 12 enters the fitting portion 21 to achieve locking between the hub and the motor, and in this state, the axial elastic member 50 is further compressed.

Of course, it should be noted that when the embodiment is based on the twentieth embodiment, the return elastic member 40 can only release the self-elastic potential energy against the gravitational potential energy of the driving member 30 to drive the driving member 30 to move.

In addition, please continue to refer to FIG. 1. The state shown in FIG. 1 is a locked state in which the driving end 31 abuts the latching portion 12, and when it is necessary to disassemble the hub and the motor, The driving member 30 is pressed away from the mounting direction of the motor, and the driving member 30 is moved to the escaping portion 32 to be aligned with the urging portion 12, and since the axial elastic member 50 is always in a compressed state in the previous locked state, when the operator presses the driving When the escaping portion 32 is aligned with the accommodating portion 12, the hub and the motor can be relatively disengaged. Under the elastic restoring force of the axial elastic member 50, the axial elastic member 50 can automatically drive the hub away from the motor. The direction is reversed, which further reduces the operator's difficulty in disassembling the hub and the motor, saving time and effort.

Example twenty-three

The embodiment is further optimized based on the twenty-second embodiment, and the reset elastic member 40 may include a compression elastic member 401 and a lower end of the compression elastic member 401. Abutting member 402. The abutting member 402 is for compressing the compression elastic member 401 under the action of the motor. The abutting member 402 can form a large contact area with the motor, so that the motor can better transmit the abutting force to the compression elastic member 401, so that the entire return elastic member 40 can be compressed more smoothly.

In this embodiment, especially when the compression elastic member 401 is a spring, the contact between the abutting member 402 and the motor is more balanced than that of the spring directly contacting the motor, and the compression of the elastic member 40 is more balanced, and the compression is more stable.

The accommodating space can move the accommodating portion 12 in the accommodating space by an external force, and has at least an opening that can engage a portion of the accommodating portion 12 outside the accommodating space to engage with the engaging portion 21. For example, the accommodation space may be a through hole 11 that is opened on the propeller.

Specifically, the holding portion 12 may be a rigid ball. Alternatively, the latching portion 12 is a rigid pin and has a curved guide surface at both ends of the rigid pin to reduce the friction between the latching portion 12 and the driving member 30, so that The latching portion 12 can be driven more easily by the driving member 30, so that the operation is smoother and the mounting between the propeller and the motor is convenient.

In the unlocked state, the catching portion 12 and the relief portion 32 are always aligned, and the driving end 31 relieves the latching portion 12. When the driving member 30 slides relative to the propeller, the catching portion 12 can be disengaged by the relief portion 32 and enter the mating portion 21 under the abutment of the driving end 31 to switch to the locked state.

It should be noted that the "unlocked state" described in this embodiment may refer to all states except the locked state, specifically including the state before the propeller and the motor shaft are relatively mounted, that is, the state before preparation for installation, The state of the motor shaft in Fig. 1 before being assembled to the propeller; and the momentary unlocked state after the propeller and the motor shaft are switched to the unlocked state in the locked state. Of course, in other embodiments, the "unlocked state" corresponds to the "locked state", and there is an intermediate state between the "unlocked state" and the "locked state".

It can be understood that in this embodiment, the latching portion 12 and the relief portion 32 are always aligned. "Alignment" does not mean that the latching portion 12 matches the shape of the relief portion 32, but only refers to the positional correspondence.

In the present embodiment, when in the unlocked state, in particular, in the state before the installation of the propeller and the motor shaft, the relief portion 32 is aligned with the catching portion 12, whereby when the motor shaft is assembled into the propeller, The holding portion 12 can be abutted into the relief portion 32 by the motor shaft, and the motor shaft can be directly installed into the propeller without requiring additional operation by the operator, and the operation is simple and convenient. When the motor shaft is inserted into the engaging portion 21 and the latching portion 12 is aligned, the driving member 30 can be moved such that the avoiding portion 32 is offset from the latching portion 12, and the driving end 31 is caused to abut the latching portion 12, and the latching portion 12 is caused to be engaged. The card is inserted into the engaging portion 21, and further, the propeller and the motor shaft are locked.

Example twenty seven

The embodiment is based on the twenty-sixth embodiment. Further, an axial elastic member 50 may be disposed between the propeller and the driving member 30, and the axial elastic member 50 is configured to relatively lock the driving member in the unlocked state. The portion 12 is axially positioned. It should be noted that since the propeller and the motor shaft are respectively a propeller and a motor, the axial direction in this embodiment refers to the direction of the central axis of rotation of the propeller and the motor shaft. The axial elastic member 50 may be a cylindrical spring, a rubber block or other elastic device, and is not particularly limited in this embodiment.

Specifically, the propeller may include a mounting protrusion 111 for the power supply shaft to be inserted through. The mounting convex portion 111 may have a cylindrical shape, and a through hole may be formed in the cylindrical wall of the cylindrical mounting convex portion, and the through hole forms an accommodating space for the holding portion 12 to be accommodated.

The mounting protrusion 113 may be integrally molded with the propeller, and specifically, a mounting hole for mounting the mounting protrusion 113 may be formed in the propeller. A guide passage 1111 for sliding the driving member 30 may be formed between the outer side wall of the mounting boss 113 and the inner wall of the mounting hole of the propeller. The driving member 30 may be a columnar body, and a boss portion 33 having a larger cross section than the upper portion may be formed at a lower portion of the columnar body. The outer side surface of the boss portion 33 is engaged with the side wall of the guide passage 1111, and the relief portion 32 is formed on the inner side surface of the boss portion 33. The boss portion 33 at the bottom end of the relief portion 32 forms the above-described drive end 31.

a positioning flange is formed on the propeller and at one end of the mounting hole facing away from the mounting protrusion 111 1112, a gap is further formed between the upper outer side of the driving member 30 and the hole wall of the mounting hole, and the axial elastic member 50 may be disposed in the gap and between the positioning flange 1112 and the boss portion 33 of the driving member 30. .

Of course, the above-mentioned arrangement of the axial elastic member 50, the shape of the driving member 30, and the shape of the propeller are only preferred embodiments, and the present invention is not limited to the above embodiments, and those skilled in the art can design according to actual conditions. Other similar structures that can implement the corresponding functions are not limited in the present invention.

In this embodiment, the driving member 30 is pressed at a preset position by using the axial elastic member 50. In particular, the driving member 30 can be pressed at the position where the avoiding portion 32 and the holding portion 12 are aligned in the unlocked state. The position of the driving member 30 is kept from swaying, and thus, the escaping portion 32 can always be with the accommodating portion 12 before the motor shaft is assembled to the propeller, and before the mating portion 21 of the motor shaft is aligned with the engaging portion 12 of the propeller. The alignment is such that the catch portion 12 can be reliably held by the motor shaft into the relief portion 32 before switching to the locked state.

Example twenty eight

The embodiment is based on the twenty-seventh embodiment. Further, the driving member 30 may further be provided with a reset elastic member 40. The return spring 40 is used to drive the drive member 30 to slide relative to the propeller to effect switching from the unlocked state to the locked state. The reset elastic member 40 may specifically be a component that can store elastic potential energy under an external force, and may be, for example, a spring, a rubber, or the like. The driving member 30 is slidable relative to the propeller by the return elastic member 40.

In the present embodiment, the return elastic member 40 may be disposed between the driving member 30 and the motor shaft. In the unlocked state, the return elastic member 40 can be gradually compressed by the motor shaft until the motor shaft is moved until the mating portion 21 is aligned with the catch portion 12, and the return elastic member 40 triggers the movement of the drive member 30. Specifically, the return elastic member 40 may be in a natural extension state or in a compressed state before the motor shaft is mounted to the propeller, and the return elastic member 40 may be abutted by the motor shaft during the mounting of the motor shaft to the propeller. Constantly compressed or further compressed, when the elastic potential energy stored by the return elastic member 40 due to compression reaches a preset value, the return elastic member 40 can release the elastic potential energy in a direction away from the motor shaft, thereby driving the driving member 30 to move. The latching portion 12 is abutted so that the latching portion 12 enters the mating portion 21 to achieve locking between the propeller and the motor shaft.

Of course, those skilled in the art can understand that the return elastic member 40 can be fixedly coupled with the driving member 30, or the return elastic member 40 can be pressed only between the driving member 30 and the motor shaft. Of course, when the reset elastic member 40 is fixedly coupled to the driving member 30, the reset elastic member 40 is not easy. The structure is more stable when it is detached from the driving member 30.

In particular, when the motor shaft is mounted on the propeller, the relief portion 32 on the drive member 30 is aligned with the catch portion 12 on the propeller, and the return elastic member 40 can be in a naturally elongated state or compressed, based on the twenty-seventh embodiment. In the state, when the motor shaft is mounted to the propeller, the motor shaft abuts the return elastic member 40, and the return elastic member 40 is continuously compressed by the motor shaft, and the elastic potential energy stored in the reset elastic member 40 is greater than the gravitational potential energy of the driving member. And the sum of the elastic potential energy of the axial elastic member, at this time, the return elastic member 40 is elongated in a direction away from the motor shaft, thereby driving the driving member 30 to move, so that the driving end 31 of the driving member 30 abuts the holding portion 12, The engagement portion 12 is caused to enter the fitting portion 21 to achieve locking between the propeller and the motor shaft, and in this state, the axial elastic member 50 is further compressed.

Of course, it should be noted that when the embodiment is based on the twenty-sixth embodiment, the reset elastic member 40 can only release the self-elastic potential energy against the gravitational potential energy of the driving member 30, and the driving member 30 is moved.

In addition, please continue to refer to FIG. 1. The state shown in FIG. 1 is a locked state in which the driving end 31 abuts the latching portion 12, and when the propeller and the motor shaft need to be disassembled, The driving direction of the driving member 30 is pressed away from the driving direction of the motor shaft, and the driving member 30 is moved to the escaping portion 32 to be aligned with the holding portion 12, and since the axial elastic member 50 is always in a compressed state in the previous locking state, when the operator presses The driving member 30, once the avoiding portion 32 is aligned with the holding portion 12, the propeller and the motor shaft can be relatively disengaged. Under the elastic restoring force of the axial elastic member 50, the axial elastic member 50 can automatically drive the propeller away from the motor shaft. The direction is reversed, which further reduces the operator's difficulty in disassembling the propeller and the motor shaft, saving time and effort.

Example twenty nine

The embodiment is further optimized based on the twenty-eighth embodiment of the embodiment. Specifically, the reset elastic member 40 may include a compression elastic member 401 and an abutting member 402 disposed at a lower end of the compression elastic member 401. The abutting member 402 is for compressing the compression elastic member 401 under the action of the abutment of the motor shaft. The abutting member 402 can form a large contact area with the motor shaft, so that the motor shaft can better transmit the abutting force to the compression elastic member 401, so that the entire return elastic member 40 can be compressed relatively smoothly.

In this embodiment, especially when the compression elastic member 401 is a spring, the contact between the abutting member 402 and the motor shaft is more balanced than that of the spring directly contacting the motor shaft, and the compression force is more balanced, and the compression is more stable. .

Specifically, the reset elastic member 40 may be in a natural extension state or in a compressed state before the propeller and the motor are installed, and the reset elasticity is performed when the other of the propeller and the motor is mounted to one of the propeller and the motor. The member 40 can be continuously compressed or further compressed by the other of the propeller and the motor. When the elastic potential energy stored by the return elastic member 40 due to compression reaches a preset value, the return elastic member 40 can be moved away from the propeller and the motor.

When the other of the propeller and the motor is mounted to one of the propeller and the motor, the other of the propeller and the motor abuts the return elastic member 40. The return elastic member 40 is continuously compressed by the other of the propeller and the motor. When the elastic potential energy stored by the return elastic member 40 is greater than the sum of the gravitational potential energy of the driving member and the elastic potential energy of the axial elastic member, at this time, The return elastic member 40 is elongated in a direction away from the other of the propeller and the motor, thereby driving the driving member 30 to move, so that the driving end 31 of the driving member 30 abuts the latching portion 12, so that the latching portion 12 enters the mating portion 21 The locking between the propeller and the motor is achieved, in which state the axial elastic member 50 is further compressed.

Of course, it should be noted that when the embodiment is based on the sixty-sixth embodiment, the reset elastic member 40 can only release the self-elastic potential energy against the gravitational potential energy of the driving member 30 to drive the driving member 30 to move.

In addition, please continue to refer to FIG. 1. The state shown in FIG. 1 is a locked state in which the driving end 31 abuts the latching portion 12, and when it is necessary to disassemble the propeller and the motor, it can be separated The mounting direction of the other of the propeller and the motor presses the driving member 30, and the driving member 30 moves to the escaping portion 32 to be aligned with the urging portion 12, and since the axial elastic member 50 is always in a compressed state in the previous locked state, When the operator presses the driving member 30, once the avoiding portion 32 is aligned with the holding portion 12, the propeller and the motor can be relatively disengaged. Under the elastic restoring force of the axial elastic member 50, the axial elastic member 50 can automatically drive the propeller and One of the motors is ejected in a reverse direction away from the other of the propeller and the motor, thereby further reducing the operator's difficulty in disassembling the propeller and the motor, saving time and effort.

The mounting convex portion 111 may have a cylindrical shape, and a through hole may be formed in the cylindrical wall of the cylindrical mounting convex portion, and the through hole forms an accommodating space for the holding portion 12 to be accommodated.

The mounting protrusion 111 may be integrally molded with one of the propeller and the motor. Specifically, one of the propeller and the motor may be formed with a mounting hole for mounting the mounting protrusion 111. A guide passage 1111 for sliding the driving member 30 may be formed between the outer side wall of the mounting boss 111 and the inner wall of the mounting hole of one of the propeller and the motor. The driving member 30 may be a columnar body, and a boss portion 33 having a larger cross section than the upper portion may be formed at a lower portion of the columnar body. The outer side surface of the boss portion 33 is engaged with the side wall of the guide passage 1111, and the relief portion 32 is formed on the inner side surface of the boss portion 33.

The position of the driving member 30 is kept free from swaying, so that when the other of the propeller and the motor is assembled to one of the propeller and the motor, and on the other of the propeller and the mating portion 21 of the motor and the propeller and the motor Before the latching portion 12 is aligned, the relief portion 32 can always be aligned with the latching portion 12 such that the latching portion 12 can be reliably held by the other of the propeller and the motor into the avoiding portion 32 before switching to the locked state. .

Example eighty three

The present embodiment is based on any one of the eighty to eighty-second embodiments. Further, the locking device may further include a return elastic member 40. The return elastic member 40 is for driving the drive member 30 to slide relative to one of the propeller and the motor to effect switching from the unlocked state to the locked state. The reset elastic member 40 may specifically be a component that can store elastic potential energy under an external force, and may be, for example, a spring, a rubber, or the like. The driving member 30 is slidable relative to one of the propeller and the motor by the return elastic member 40.

In the present embodiment, the return elastic member 40 may be disposed between the driving member 30 and the other of the propeller and the motor. In the unlocked state, the return elastic member 40 can be gradually compressed by the other of the propeller and the motor until the other of the propeller and the motor moves until the mating portion 21 is aligned with the latching portion 12, the reset elastic member 40 triggers the driving member 30. mobile. Specifically, the reset elastic member 40 may be in a natural extension state or in a compressed state before the propeller and the motor are installed, and the reset elasticity is performed when the other of the propeller and the motor is mounted to one of the propeller and the motor. The member 40 can be continuously compressed or further compressed by the other of the propeller and the motor. When the elastic potential energy stored by the return elastic member 40 due to compression reaches a preset value, the return elastic member 40 can be moved away from the propeller and the motor. The direction of the other one releases the elastic potential energy, thereby driving the driving member 30 to move against the holding portion 12, so that the engaging portion 12 enters the fitting portion 21 to achieve the locking between the propeller and the motor.

Of course, those skilled in the art can understand that the return elastic member 40 can be coupled to the driving member 30. The fixing members 40 may be fixedly coupled together, or the reset elastic member 40 may be press-fitted only between the driving member 30 and the other of the propeller and the motor. Of course, when the return elastic member 40 is fixedly coupled to the driving member 30, the return elastic member 40 is not easily detached from the driving member 30, and the structure is more stable.

In particular, when the other of the propeller and the motor is mounted to one of the propeller and the motor, the relief portion 32 on the drive member 30 and the catch portion on one of the propeller and the motor are based on the eighty-second embodiment. 12 alignment, the return elastic member 40 may be in a naturally extended state or a compressed state. When the other of the propeller and the motor is mounted to one of the propeller and the motor, the other of the propeller and the motor abuts the return elastic member 40. The return elastic member 40 is continuously compressed by the other of the propeller and the motor. When the elastic potential energy stored by the return elastic member 40 is greater than the sum of the gravitational potential energy of the driving member and the elastic potential energy of the axial elastic member, at this time, The return elastic member 40 is elongated in a direction away from the other of the propeller and the motor, thereby driving the driving member 30 to move, so that the driving end 31 of the driving member 30 abuts the latching portion 12, so that the latching portion 12 enters the mating portion 21 The locking between the propeller and the motor is achieved, in which state the axial elastic member 50 is further compressed.

Of course, it should be noted that when the embodiment is based on the eighty-first embodiment, the reset elastic member 40 can only release the self-elastic potential energy against the gravitational potential energy of the driving member 30, and the driving member 30 is moved.

In addition, please continue to refer to FIG. 1. The state shown in FIG. 1 is a locked state in which the driving end 31 abuts the latching portion 12, and when it is necessary to disassemble the propeller and the motor, it can be separated The mounting direction of the other of the propeller and the motor presses the driving member 30, and the driving member 30 moves to the escaping portion 32 to be aligned with the urging portion 12, and since the axial elastic member 50 is always in a compressed state in the previous locked state, When the operator presses the driving member 30, once the avoiding portion 32 is aligned with the holding portion 12, the propeller and the motor can be relatively disengaged. Under the elastic restoring force of the axial elastic member 50, the axial elastic member 50 can automatically drive the propeller and One of the motors is ejected in a reverse direction away from the other of the propeller and the motor, thereby further reducing the operator's difficulty in disassembling the propeller and the motor, saving time and effort.

Example eighty four

The embodiment is further optimized based on the eighty-third embodiment of the embodiment. Specifically, the return elastic member 40 may include a compression elastic member 401 and an abutting member 402 disposed at a lower end of the compression elastic member 401. The abutting member 402 is for compressing the compression elastic member 401 under the action of the other of the propeller and the motor. The abutting member 402 can form a large contact area with the other of the propeller and the motor, so that the other of the propeller and the motor can transmit the abutting force better. The elastic member 401 is compressed so that the entire return elastic member 40 can be compressed relatively smoothly.

In this embodiment, especially when the compression elastic member 401 is a spring, the contact of the abutting member 402 with the other of the propeller and the motor is restored to the elastic member 40 in a manner that the spring directly contacts the other of the propeller and the motor. The force is more balanced and the compression is more stable.
