Description

Technical Field

[0001] This utility model relates to a stator assembly, specifically a stator assembly for a pedal motor, and belongs to the field of stator assembly technology. Background Technology

[0002] An electric pedal is an intelligent pedal device installed on the foot pedal of a vehicle, designed to improve the convenience and comfort of the driver. This device is driven by a motor and has the function of automatically adjusting the height and width of the pedal, providing the driver with a more personalized driving experience. In the pedal motor, the stator is the stationary part of the motor, which consists of three parts: the stator core, the stator winding, and the frame. The stator is used to generate a rotating magnetic field.

[0003] However, most existing stator assemblies have various problems. For example, in the motor stator disclosed in announcement number CN102201709B, although multiple smaller magnets are used to form a magnetic pole, the magnets are easy to manufacture and the material utilization rate is high, in this technical solution and most current motor stator assemblies, the stator core is mostly directly cured into the inner cavity of the motor housing by hot pressing assembly or epoxy resin potting. When the stator is damaged or needs to be replaced due to other reasons, the entire motor assembly needs to be disassembled. At the same time, the motor housing needs to be heated to soften the curing agent, which can easily cause secondary damage to the windings. In addition, it is time-consuming and labor-intensive, and a lot of time is required during disassembly and assembly, which seriously affects work efficiency. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the purpose of this utility model is to overcome the aforementioned shortcomings in existing technologies by proposing a stator assembly for a pedal motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stator assembly for a pedal motor includes a motor housing, a limiting seat, a stator core, and a locking mechanism. The limiting seat is fixed to the inner wall of the motor housing, the stator core is held in the limiting seat, and the locking mechanism is disposed between the limiting seat and the stator core. The locking mechanism includes a positioning rod, a positioning hole, a sliding groove, a locking rod, a locking hole, and a linkage unit. The positioning rod is fixed to one end of the stator core. The positioning hole is recessed on one side of the limiting seat. The positioning rod and the positioning hole are arranged in a one-to-one correspondence. The positioning rod is slidably engaged in the positioning hole and has an installation cavity. The linkage unit is arranged in the installation cavity. The sliding groove is arranged on the outer wall of the positioning rod and communicates with the installation cavity. The locking rod is slidably engaged in the sliding groove. The locking hole is arranged on the limiting seat and communicates with the positioning hole. The locking rod is engaged in the locking hole.

[0006] As a further embodiment of this utility model: the linkage unit includes a push rod, a leaf spring, and a limiting plate. The push rod is slidably connected to the center of one end of the positioning rod, and part of it is located inside the mounting cavity and part of it is located outside the positioning rod and abuts against the positioning hole. The limiting plate is set inside the mounting cavity. One end of the leaf spring is fixed on the limiting plate, and the bottom of the locking rod is slidably connected to the leaf spring.

[0007] As a further improvement of this utility model: the end of the leaf spring away from the limiting plate is provided with an abutment end, the abutment end has an inclined structure, is compressed in the mounting cavity, and abuts against one end of the push rod.

[0008] As a further embodiment of this utility model: the linkage unit further includes a positioning nut and a return spring. The positioning nut is located at the center of the other end of the positioning rod, and the return spring is located in the mounting cavity. One end of the return spring abuts against the limiting plate, and the other end abuts against the positioning nut.

[0009] As a further improvement of this utility model: a screw hole is provided at one end of the positioning rod near the positioning nut, and the positioning nut is threaded into the screw hole.

[0010] As a further improvement of this utility model: a rectangular plate is provided at the connection end between the positioning rod and the stator core, and a screw is provided on the rectangular plate, and the screw is detachably screwed onto the stator core.

[0011] The beneficial effects of this utility model are: In this invention, a positioning rod is connected to a positioning hole, and a push rod abuts against the tail end of the positioning hole. This allows the push rod to slide within the positioning rod, simultaneously pushing the leaf spring and the limiting plate to move as a whole. When the abutting end moves to the slide groove, it is lifted by the spring force of the leaf spring, thereby driving the locking rod to move and engage in the locking hole. This achieves a quick locking effect on the limiting seat and the stator core. After locking, the abutting end is also engaged in the slide groove. Through the linkage mechanism of the slide rod and spring, workers can perform manual operation when disassembling and assembling the stator core, which is simple, efficient, and practical. It also avoids secondary damage to other components. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] like Figures 1 to 4 As shown, a stator assembly for a pedal motor includes a motor housing 1, a limiting seat 2, a stator core 3, and a locking mechanism 4. The limiting seat 2 is fixed to the inner wall of the motor housing 1, the stator core 3 is inserted into the limiting seat 2, and the locking mechanism 4 is disposed between the limiting seat 2 and the stator core 3. The locking mechanism 4 includes a positioning rod 41, a positioning hole 42, a sliding groove 43, a locking rod 44, a locking hole 45, and a linkage unit. The positioning rod 41 is fixed to one end of the stator core 3. The positioning hole 42 is recessed and set on one side of the limit seat 2. The positioning rod 41 and the positioning hole 42 are set one-to-one, and the positioning rod 41 is slidably engaged in the positioning hole 42. An installation cavity is set in the positioning rod 41. The linkage unit is set in the installation cavity. The sliding groove 43 is set on the outer wall of the positioning rod 41 and communicates with the installation cavity. The locking rod 44 is slidably engaged in the sliding groove 43. The locking hole 45 is set on the limit seat 2 and communicates with the positioning hole 42. The locking rod 44 is engaged in the locking hole 45. The linkage unit includes a push rod 46, a leaf spring 47, and a limiting plate 48. The push rod 46 is slidably connected to the center of one end of the positioning rod 41, and part of it is located inside the mounting cavity and part of it is located outside the positioning rod 41 and abuts against the positioning hole 42. The limiting plate 48 is set inside the mounting cavity. One end of the leaf spring 47 is fixed to the limiting plate 48. The bottom of the locking rod 44 is slidably connected to the leaf spring 47. The end of the leaf spring 47 away from the limiting plate 48 is provided with an abutting end 49. The abutting end 49 has a beveled structure and is compressed inside the mounting cavity and abuts against one end of the push rod 46. The linkage unit also includes a positioning nut 410 and a return spring 411. The positioning nut 410 is located at the center of the other end of the positioning rod 41, and the return spring 411 is located in the mounting cavity. One end of the return spring 411 abuts against the limit plate 48, and the other end abuts against the positioning nut 410.

[0016] In this utility model, the positioning rod 41 is connected to the positioning hole 42, and the push rod 46 abuts against the tail end of the positioning hole 42, thereby causing the push rod 46 to slide within the positioning rod 41 and simultaneously pushing the leaf spring 47 and the limiting plate 48 to move as a whole. When the abutting end 49 moves to the slide groove 43, the abutting end 49 is lifted under the action of the spring force of the leaf spring 47, thereby driving the locking rod 44 to move and engage in the locking hole 45, achieving a quick locking effect on the limiting seat 2 and the stator core 3. After locking, the abutting end 49 is also engaged in the slide groove 43. Through the linkage mechanism of the slide rod and spring, the operator can perform manual operation when disassembling and assembling the stator core 3, which is simple, efficient and practical, and can also avoid secondary damage to other components. Example 2

[0017] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes: A screw hole is provided at one end of the positioning rod 41 near the positioning nut 410. The positioning nut 410 is threaded into the screw hole. The screw hole allows the positioning nut 410 to be quickly installed and removed. At the same time, the compression of the return spring 411 can be adjusted through the positioning nut 410.

[0018] A rectangular plate 5 is provided at the connection end between the positioning rod 41 and the stator core 3, and a screw is provided on the rectangular plate 5. The screw is detachably screwed onto the stator core 3. The rectangular plate and the screw allow for quick assembly and disassembly between the positioning rod 41 and the stator core 3.

[0019] Working principle: When using this stator assembly, first place the stator core 3 in the limiting seat 2 and align the positioning rod 41 with the positioning hole 42. When the push rod 46 moves to the end of the positioning hole 42, the push rod 46 slides under pressure and simultaneously pushes the leaf spring 47 and the limiting plate 48 to move as a whole. When the abutment end 49 moves to the slide groove 43, the abutment end 49 is lifted under the action of the spring force of the leaf spring 47, thereby driving the locking rod 44 to move and engage in the locking hole 45, thus achieving the locking effect on the limiting seat 2 and the stator core 3. After locking, the abutment end 49 is also engaged in the slide groove 43. When it is necessary to disassemble the stator core 3, use an external tool to push the locking rod 44 through the locking hole 45. At this time, the locking rod 44 pushes the abutment end 49 to deform until it separates from the slide groove 43. At this time, the leaf spring 47 is reset under the action of the return spring 411, and the locking rod 44 is separated from the locking hole 45.
