Technical Field

[0001] The utility model relates to the field of kite wheels, in particular to an electric kite wheel capable of freely retracting and releasing lines. Background Art

[0002] The existing electric kite wheel needs to be manually switched when winding and releasing the line, and the motor needs to be separated from the line reel before winding the line. The steps are very troublesome. If the operation is improper, the motor is easily damaged, and the maintenance cost is high. The utility model provides an electric kite wheel technology that can freely reel in and release the line, which is more convenient and practical to operate and not easy to be damaged. Utility Model Content

[0003] The technical problem to be solved by the utility model is that, in view of the fact that the current electric kite wheel needs to be manually switched when winding and releasing the line, the steps are very troublesome. If the operation is improper, the motor is easily damaged and the maintenance cost is high. An electric kite wheel with free retractable line is provided.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions: an electric kite wheel with free retractable line, which includes:

[0005] Motor;

[0006] Rotating shaft;

[0007] A hand crank for manual reeling;

[0008] Coupling device;

[0009] A reel for storing kite lines;

[0010] transmission shaft;

[0011] The motor is connected to the rotating shaft, the rotating shaft drives the transmission shaft to rotate, the coupling device is installed on the transmission shaft, and the wire drum is installed on the coupling device; the hand crank is connected to the rotating shaft.

[0012] As a further optimization scheme of the utility model, it also includes a one-way rotation structure, the motor transmission is connected to the one-way rotation structure, and the one-way rotation structure drives the rotating shaft to rotate in one direction.

[0013] As a further optimization solution of the utility model, the coupling device is composed of a coupling member and a coupling push rod, and the coupling push rod controls the movement of the coupling member and thus controls the rotation of the wire drum.

[0014] To further optimize the solution, the coupling parts include a bushing, a friction plate, a pressure plate, and a reset part. The pressure plate and the friction plate are both sleeved on the transmission shaft, and the pressure plate drives the bushing to rotate through friction contact with the friction plate.

[0015] According to a further optimized solution, the transmission shaft is a flat shaft with at least one plane, and a shaft hole matching the transmission shaft is opened on the clamping plate, and the transmission shaft drives the clamping plate to rotate.

[0016] As a further optimization solution of the utility model, a through hole is provided on the friction plate, and the diameter of the through hole is larger than the diameter of the transmission shaft.

[0017] According to a further optimization scheme, the one-way rotating structure is a one-way bearing or a one-way ratchet.

[0018] According to a further optimization scheme, the one-way rotating structure is a one-way bearing, and the one-way bearing also includes a cutter and an external gear. The inner ring of the one-way bearing is fixed to the rotating shaft by a cutter, and the outer ring of the one-way bearing is fixed to the external gear by a cutter.

[0019] A further optimization scheme is that the one-way bearing or the one-way ratchet includes an outer ring, an inner ring, and a one-way piece for realizing one-way rotation of the outer ring and the inner ring, the one-way piece is obliquely installed between the inner ring and the outer ring, and the orientations of the one-way pieces are the same, and the length of the one-way piece is greater than the distance between the outer ring and the inner ring.

[0020] According to a further optimized solution, the reset element is arranged between the friction plate and the pressure plate.

[0021] Beneficial effects:

[0022] By setting a one-way rotating structure in the electric kite wheel, the problem that the existing electric kite wheel cannot be operated manually and electrically at the same time is solved. In an emergency, the line can be manually retrieved directly without switching on and off, avoiding major safety hazards.

[0023] By arranging a one-way piece in the one-way bearing and arranging clamping cuts inside and outside the one-way bearing, the inner ring and outer ring of the one-way bearing are respectively fixed to the rotating shaft and the external gear, so that the one-way bearing drives the rotating shaft to rotate under the drive, simplifies the one-way rotation structure, and facilitates the replacement of the one-way bearing.

[0024] By providing a coupling device, the problem of manually switching the switch when winding and releasing the line is solved, and the rotation of the wire drum can be achieved through the coupling device.

[0025] By arranging a reset piece between the friction plate and the pressing plate, it is ensured that no friction occurs between the friction plate and the pressing plate under normal conditions, thereby causing the wire drum to rotate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Example 1

[0033] like Figure 1 The electric kite wheel for freely retracting and releasing the line comprises a motor 1, a rotating shaft 2, a hand crank 3, a coupling device 4, a wire drum 5, and a transmission shaft 6, wherein the hand crank is used for manually reeling in the line, and the coupling device 4 is used for rotating the wire drum, wherein the motor 1 is transmission-connected to the rotating shaft 2, the rotating shaft 2 drives the transmission shaft 6 to rotate, the coupling device 4 is mounted on the transmission shaft 6, the wire drum 5 is mounted on the coupling device 4, and the hand crank 3 is transmission-connected to the rotating shaft 2.

[0034] The coupling device 4 is composed of a coupling member 41 and a coupling push rod 42. The coupling member 41 is rotated by turning the coupling push rod 42, thereby driving the wire drum to rotate.

[0035] like Figure 2 As shown, the coupling member 41 includes a sleeve 411, a friction plate 412, a clamping plate 413, and a reset member 414. The clamping plate 413 and the friction plate 412 are both sleeved on the transmission shaft 6. The clamping plate 413 can drive the friction plate 412 to rotate through friction contact. The friction plate 412 is fixed on the sleeve 411 and can drive the sleeve to rotate. The reset member 414 is arranged between the clamping plate 413 and the friction plate 412 to prevent the friction plate 412 and the clamping plate 413 from contacting each other under normal conditions. In this embodiment, the reset member is a spring.

[0036] In this embodiment, the transmission shaft is a flat shaft with at least one plane, and the pressing plate 413 is provided with an axial hole matching the transmission shaft 6, so that the transmission shaft can drive the pressing plate 413 to rotate, and the pressing plate 413 can move laterally on the transmission shaft. A through hole is provided on the friction plate 412, and the diameter of the through hole is larger than the diameter of the transmission shaft 6, so as to prevent the transmission shaft 6 from driving the friction plate to rotate.

[0037] During use, the friction plate 412 and the pressing plate 413 are in a separated state under normal conditions. When the wire drum needs to be rotated, the coupling push rod 42 is toggled so that the pressing plate approaches 413 and finally contacts the friction plate 413. The pressing plate 413 rotates under the drive shaft 6, and drives the friction plate 412 to rotate. The friction plate drives the coupling member 41 to rotate, and the coupling member 41 drives the wire drum to rotate. After use, the pressing plate 413 is reset by pulling back the coupling push rod 42 and under the action of the reset member 414.

[0038] Example 2

[0039] The electric kite wheel with free retractable line shown in Example 1 is different in that it also includes a one-way rotating structure 7, the motor 1 is connected to the one-way rotating structure 7, and the one-way rotating structure 7 drives the rotating shaft 2 to rotate in one direction. The one-way rotating structure 7 can be a one-way bearing or a one-way ratchet.

[0040] like Figure 3 As shown, in this embodiment, when the one-way rotating structure 7 is a one-way bearing 71, the one-way bearing 71 is fixed to the rotating shaft 2 or the rotating shaft 2 6 by arranging a cutter 711 and an outer gear 712 on the one-way bearing 71. The inner ring of the one-way bearing 71 is fixed to the rotating shaft 2 by the cutter 711, and the outer ring of the one-way bearing 71 is fixed to the outer gear 712 by the cutter 711. When the motor drives the outer gear to rotate unidirectionally in a certain direction, the shaft fixed to the inner ring of the one-way bearing 71 will also be driven to rotate, otherwise it will not rotate. Therefore, when the shaft also rotates unidirectionally in this direction, the outer gear 712 fixed to the outer ring of the one-way bearing 71 will not rotate. The one-way bearing can also use other one-way structures.

[0041] like Figure 4 As shown, when the one-way rotating structure 7 is a one-way ratchet, the one-way ratchet consists of a ratchet outer ring, a ratchet inner ring, and a one-way pawl. The one-way pawl is fixed to the ratchet inner ring, and the ratchet inner ring is relatively fixed to the rotating shaft 2. One-way rotation is achieved under the relative action of the one-way pawl and the teeth of the ratchet outer ring.

[0042] In addition to the one-way bearing or the one-way ratchet, to achieve one-way rotation, the one-way rotation structure 7 may also include an outer ring, an inner ring, and a one-way member for achieving one-way rotation of the outer ring and the inner ring. The one-way member is installed obliquely between the inner ring and the outer ring, and the directions of the one-way members are the same. The length of the one-way member is greater than the distance between the outer ring and the inner ring. This structure effectively prevents the reversal of the one-way rotation structure 7.

[0043] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
