Please select the most similar patent number from A, B, C and D. Which number is?
Disclosed are an electronic coil and an electronic expansion valve having same. The electronic coil comprises: a coil main body (10); a wire plug part (20), which is arranged on the coil main body (10), wherein the wire plug part (20) comprises a coil-connecting part (21) and a housing (22), a pin (23) is arranged on the coil-connecting part (21), and the housing (22) covers the coil-connecting part (21); a circuit board (30), wherein the circuit board (30) is arranged on the pin (23) in a penetrating manner; and a supporting part (40), which is arranged on the coil-connecting part (21), wherein the supporting part (40) is configured to be attached to at least part of the circuit board (30), and the supporting part (40) is used for supporting the circuit board (30), such that a gap is present between the coil-connecting part (21) and the circuit board (30). The technical solution can solve the technical problem of the poor welding performance of a circuit board of an electronic coil in the prior art.
A: A solenoid valve coil, comprising: a solenoid valve coil body (10); and a lead assembly (20). The lead assembly (20) comprises a connector (21) and a wire (22); the connector (21) comprises a wire passing hole (2121); an end portion of the wire (22) extends into the wire passing hole (2121) and can be electrically connected to the solenoid valve coil body (10); the wire (22) and an inlet of the wire passing hole (2121) are sealed. The solenoid valve coil can effectively solve the problem in the prior art that the sealing performance of coils is poor.
B: A bell assembly and a vehicle having same. The bell assembly is to be provided at a vehicle handlebar (40). The bell assembly comprises: a connection portion (10), wherein an insertion passage is arranged at the connection portion (10), such that the connection portion (10) can be sleeved onto the vehicle handlebar (40) by means of the insertion passage; a bell component (20) provided at the connection portion (10); and a first engagement portion (30) provided at the connection portion (10), wherein the first engagement portion (30) is positioned inside the insertion passage, such that when the connection portion (10) is sleeved onto the vehicle handlebar (40), the first engagement portion (30) is engaged with and positioned by a second engagement portion (41) of the vehicle handlebar (40). The invention can solve the technical problem in the art in which a bell assembly is not convenient to operate and use.
C: An image stabilization structure, an image stabilization system, and a photographic device. The image stabilization structure comprises a housing (10) and a base (20), the housing (10) covering the base (20) and forming an accommodating space with the base (20). Same further comprises a lens support body (30), a frame (40), a lateral magnet (50), a lateral coil (60), a magnetic attraction plate (70) and a plurality of balls (80), which are arranged in the accommodating space, wherein the lateral magnet (50) is arranged on one side of the lens support body (30); the lateral coil (60) is arranged on the frame (40) and corresponding to the lateral magnet (50) to enable the lens support body (30) to be movably arranged on the frame (40) in a Z-direction; the plurality of balls (80) are arranged between the frame (40) and the lens support body (30) to enable the lens support body (30) to smoothly slide relative to the frame (40); and the magnetic attraction plate (70) is arranged on the side of the lateral coil (60) that is away from the lateral magnet (50). The problem of the poor usage performance of photographic devices in the prior art is thus solved.
D: Provided are an anti-shake structure, anti-shake system, and camera apparatus; the anti-shake structure comprises an outer housing (10) and a base (20); the outer housing (10) is coveringly arranged on the base (20) and forms an accommodating space between it and the base (20); the anti-shake structure also comprises, arranged in the accommodating space: a lens support body (30), a frame (40), a plurality of driving magnets (50), a plurality of driving coils (60), a lateral magnet (70), a lateral coil (80), and a plurality of balls (90); the lateral magnet (70) is arranged on one side of the lens support body (30); the lateral coil (80) is arranged, corresponding to the lateral magnet (70), on the frame (40) such that the lens support body (30) is movably arranged on the frame (40) in the Z-direction; the plurality of balls (90) are arranged between the frame (40) and the lens support body (30), enabling the lens support body (30) to slide smoothly with respect to the frame (40); the driving magnet (50) is arranged on the side of the frame (40) away from the lens support body (30); the plurality of driving coils (60) are arranged corresponding to the plurality of driving magnets (50), and the driving coil (60) is arranged on the base (20), solving the problem in the prior art of poor anti-shake performance of camera apparatuses.
