Description

Technical Field

[0001] This utility model relates to the field of hub motor technology, specifically a hub motor. Background Technology

[0002] In-wheel motor technology, also known as wheel-mounted motor technology, is characterized by integrating the power unit, transmission unit, and braking unit into the wheel hub, which greatly simplifies the mechanical parts of electric vehicles. During the installation of the in-wheel motor, it is necessary to connect the wiring to the in-wheel motor, and the in-wheel motor itself is used in this process.

[0003] The existing technology has the following problems:

[0004] Hub motors require a power supply during use. When connecting to the power supply, the wires need to be extended into the interior of the hub motor. However, existing hub motors do not facilitate the wire lead-out operation, making it difficult to extend the wires into the interior of the hub motor for connection. Furthermore, it is not easy to seal the wires and hub motor after connection, which makes it easy for water to enter the interior of the hub motor through the wire connection during use. Utility Model Content

[0005] The purpose of this invention is to provide a hub motor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hub motor, comprising a hub motor body and an mounting assembly disposed on the hub motor body. The hub motor body is provided with a lead wire assembly and a mounting assembly. The lead wire assembly includes a fixed cylinder fixedly mounted on the rear side of the hub motor body. A lead wire groove is formed on the inner side of the fixed cylinder. Two sealing brackets are movably mounted on the inner side of the lead wire groove. A fixing ring is fixedly mounted on the outer periphery of the fixed cylinder. Multiple bolt posts are fixedly connected to one side of the fixing ring. Two fixing brackets are movably connected to the rear side of the fixing ring. The multiple bolt posts all penetrate the fixing brackets. The mounting assembly includes a rotating rod rotatably mounted on the front end of the hub motor body. The front end of the rotating rod is quadrilateral in shape. A fixing block is sleeved on the outer side of the rotating rod. The fixing block is fixedly connected to the rotating rod. A fixing plate is fixedly mounted on the front end of the fixing block.

[0007] By fitting the fixing block onto the outside of the rotating rod and then fixing the fixing plate to the front end of the fixing block, the hub and the hub motor body can be fixed together by fixing the hub and the mounting bolt. By inserting the wire from the rear end of the fixing cylinder and using the angle of the lead wire groove inside the fixing cylinder to guide the wire, the wire can be easily passed through the wiring hole into the hub motor body for electrical connection. By clamping the two sealing brackets on the outside of the wire and then inserting the sealing brackets into the lead wire groove, and by clamping the two fixing brackets around the wire and aligning the two fixing brackets with the fixing ring, the sealing brackets are gradually pushed into the lead wire groove by pushing the fixing brackets towards the fixing ring. The angle between the lead wire groove and the sealing bracket can seal the wiring point of the hub motor body. The hub motor body can drive the rotating rod to rotate, which in turn drives the fixing block to rotate. The fixing block can drive the brake disc and the fixing plate to rotate.

[0008] Preferably, the mounting assembly includes a mounting base fixedly mounted on the rear side of the hub motor body and multiple mounting bolts fixedly connected to the front side of the mounting plate. The mounting base is located below the mounting cylinder, and the mounting plate and the mounting block are fixed together by a second mounting bolt. The hub motor body can be mounted and fixed to the vehicle using the mounting base, the hub can be mounted on the mounting plate using the mounting bolts, and the mounting plate and the mounting block can be fixed together using the second mounting bolts.

[0009] Preferably, a caliper is fixedly mounted on the front side of the hub motor body. The caliper is located on one side of a fixed block, and a brake disc is fixedly connected to the periphery of the fixed block. One side of the brake disc extends into the inside of the caliper. When the fixed block is rotated by the rotating rod, the brake disc is simultaneously rotated. The caliper can clamp and rub the brake disc to achieve braking operation.

[0010] Preferably, both fixing brackets have multiple fixing holes on their inner sides, each fixing hole corresponding to a bolt post. The inner sides of both fixing brackets have slots, and each bolt post has a nut threaded onto its outer side. Each nut is located on the rear side of the fixing bracket. The bolt post can pass through the fixing holes, and when the nut is screwed onto the outer side of the bolt post, it compresses the fixing bracket, causing it to move towards the fixing ring.

[0011] Preferably, the hub motor body has a wiring hole corresponding to the lead wire groove on its rear side, and sealant is fixedly installed on the outer side of each sealing frame. Sealing grooves are formed on the inner sides of the two sealing frames, and these sealing grooves correspond to the wiring holes. The wiring holes allow wires to extend into the hub motor body for electrical connection, and the sealant seals the connection between the sealing frame, the lead wire groove, and the wires.

[0012] Preferably, the fixing block and the rotating rod are fixed together by a first fixing bolt, the first fixing bolt and the fixing block are threaded together, and the top of the rotating rod has a fixing groove corresponding to the first fixing bolt. By rotating the first fixing bolt, the bottom of the first fixing bolt extends into the fixing groove, thereby fixing the fixing block and the rotating rod together.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By configuring a fixed cylinder, a sealing frame, and the interplay between the fixed cylinder and the sealing frame, the wire is inserted from the rear end of the fixed cylinder. The wire is then guided through the lead-in groove inside the fixed cylinder, allowing it to easily pass through the wiring hole and enter the hub motor body for electrical connection. Two sealing frames are then positioned on the outside of the wire, inserting them into the lead-in groove. The fixed frame is then connected to the fixing ring, and the fixed frame pushes the sealing frame further into the lead-in groove. The angle between the lead-in groove and the sealing frame compresses the sealant, ensuring it fully adheres to the fixed cylinder and the wire, thus sealing the wiring connection of the hub motor body.
