Description

Technical Field

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

[0002] A pedal motor housing structure is a rigid outer shell assembly used to enclose and protect the core components of the pedal motor (such as stator, rotor, coil, etc.). It also undertakes the important functions of fixing the motor, connecting the pedal mechanism, and transmitting force. It is the basic structural carrier for the pedal motor to realize mechanical movement and power output. In terms of composition, it usually includes key parts such as main housing, end caps, and connection interfaces. The main housing is mostly a hollow cylindrical or box-shaped structure with reserved installation space inside to accommodate the core components of the motor.

[0003] However, most existing pedal motors have various problems. For example, in the motor disclosed in publication number CN217824917U for preventing loosening, although it achieves the effect of preventing bolt loosening and solves the problem of dirt clogging inside the threaded hole, and can also seal both ends of the threaded hole, in this technical solution and most current housing structures, the pedal motor housing structure mostly adopts a bolt and threaded hole connection method during assembly. Although this connection method can meet the basic requirements of housing assembly to a certain extent and achieve a stable connection of various motor components, it has revealed obvious defects in actual use: When the pedal motor is subjected to significant external force during operation, the screw holes on the housing are prone to stripping due to excessive stress. Once stripping occurs, existing solutions are often quite difficult. Common methods include re-tapping, installing wire thread inserts, filling and repairing, or replacing parts. When the stripping is minor, thread repair tools can be used to repair the damaged threads, or materials such as metal filler or strong adhesive can be filled into the screw hole. After curing, the hole can be re-drilled and tapped. Alternatively, simple methods such as wrapping Teflon tape or hemp fibers around the bolt can be used to increase friction and barely maintain the connection. However, these methods have limited effectiveness, and the strength of the repaired screw hole is difficult to restore to its initial state, and there is still a risk of stripping again in subsequent use. Utility Model Content

[0004] This utility model provides a significantly different solution to the problem of overly simplistic existing technical solutions. Specifically, the purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a housing structure for a pedal motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A housing structure for a pedal motor includes a housing shell, a motor housing, mounting holes, mating holes, and a connection locking mechanism. The housing shell is mounted on the motor housing. The mounting holes are recessed in the motor housing. The mating holes are through-holes located at the edge of the housing shell, and the mounting holes and mating holes are arranged in a one-to-one correspondence. The connection locking mechanism is located between the mounting holes and the mating holes. The connection locking mechanism includes a base, a clamping plate, a bolt, a limiting rod, and an abutment unit. The base is coaxially fixed in the mounting hole. The clamping plate is fixed at the edge of the base and is provided with multiple clamping plates at equal intervals. The limiting rod is coaxially fixed to one end of the bolt. Both the bolt and the limiting rod pass through the mating hole, and the limiting rod abuts against the inner side of the clamping plate. The outer wall of the clamping plate has a wedge-shaped structure, and the abutment unit abuts against the outer side of the clamping plate.

[0006] As a further embodiment of this utility model: the abutting unit abuts the abutting cylinder, one end of the abutting cylinder is provided with a thread and is engaged with a bolt through the thread, the other end of the abutting cylinder has a conical structure, and the inner wall of the conical end slides against the outer wall of the clamping plate.

[0007] As a further embodiment of this utility model: the bolt is threaded with a locking nut and a pressure nut, and a spring washer is sleeved on the outside of the bolt, the spring washer being located between the locking nut and the pressure nut.

[0008] As a further improvement of this utility model: a positioning rod is fixed inside the base, and a positioning hole is provided at the bottom of the limiting rod, with the positioning rod and the positioning hole being provided in a one-to-one correspondence.

[0009] As a further improvement of this utility model: the top of the abutment cylinder is provided with a tool docking groove, and the tool docking groove has a polygonal structure.

[0010] As a further improvement of this utility model: a protrusion is fixed to the top inner side of the clamping plate, and the protrusion is locked to the edge of the top of the limiting rod.

[0011] The beneficial effects of this utility model are: In this invention, a connecting locking mechanism is provided, which uses an abutment cylinder to press the clamping plate, causing the clamping plate to deform and clamp the limiting rod. This achieves a limiting and locking effect on one end of the bolt, allowing it to be fixed in the mounting hole. The locking nut then connects and locks the machine housing and motor housing, avoiding the problem of stripped threads caused by pre-drilling threads in the motor housing. When a bolt strips, the unique design of the clamping plate allows for direct removal and replacement of the stripped bolt. Compared to traditional structures that require re-drilling holes or replacing the entire machine housing, this process is significantly simplified. No complex machine housing repair work by professional technicians is needed; ordinary maintenance personnel can quickly replace the bolt, greatly saving maintenance time, reducing equipment downtime, and ensuring the pedal motor can quickly return to normal operation.

[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 5As shown, a housing structure for a pedal motor includes a housing 1, a motor housing 2, mounting holes 3, mating holes 4, and a connecting locking mechanism 5. The housing 1 is mounted on the motor housing 2. The mounting holes 3 are recessed on the motor housing 2. The mating holes 4 are through-holes located at the edge of the housing 1. The mounting holes 3 and mating holes 4 are arranged in a one-to-one correspondence. The connecting locking mechanism 5 is located between the mounting holes 3 and the mating holes 4. The connecting locking mechanism 5 includes a base 51, a clamping plate 52, a bolt 53, a limiting rod 54, and an abutting unit. The base 51 is coaxially fixed in the mounting hole 3. The clamping plate 52 is fixed at the edge of the base 51 and multiple clamping plates are equidistantly arranged. The limiting rod 54 is coaxially fixed to one end of the bolt 53. Both the bolt 53 and the limiting rod 54 pass through the docking hole 4, and the limiting rod 54 abuts against the inner side of the clamping plate 52. The outer wall of the clamping plate 52 has a wedge-shaped structure, and the abutting unit abuts against the outer side of the clamping plate 52. The abutting unit includes an abutting cylinder 55. One end of the abutting cylinder 55 is provided with a thread and is engaged with a bolt 53 through the thread. The other end of the abutting cylinder 55 has a tapered structure, and the inner wall of the tapered end slides against the outer wall of the clamping plate 52. Bolt 53 is threaded with a locking nut 56 and a pressure nut 7, and a spring washer 6 is sleeved on the outside of bolt 53, with the spring washer 6 located between the locking nut 56 and the pressure nut 7.

[0016] In this utility model, by setting a connecting locking mechanism 5, the clamping plate 52 is pressed by the abutment cylinder 55, causing the clamping plate 52 to deform and clamp the limiting rod 54, thereby achieving a limiting and locking effect on one end of the bolt 53, so that one end can be fixed in the mounting hole 3, and in conjunction with the locking nut 56, the housing 1 and the motor housing 2 are connected and locked, avoiding the situation of stripping the screw holes that are pre-drilled on the motor housing 2. When the bolt 53 strips, due to the unique design of the clamping plate 52, the stripped bolt 53 can be directly removed and replaced. Compared with the traditional structure of re-drilling holes or replacing the entire housing, the operation steps are greatly simplified. There is no need for professional technicians to perform complicated housing repair work. Ordinary maintenance personnel can quickly complete the bolt replacement, greatly saving maintenance time, reducing equipment downtime, and ensuring that the pedal motor can quickly resume normal operation. Example 2

[0017] like Figures 1 to 5 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes: A positioning rod 57 is fixed inside the base 51, and a positioning hole 58 is provided at the bottom of the limiting rod 54. The positioning rod 57 and the positioning hole 58 are set one-to-one. The positioning rod 57 and the positioning hole 58 limit the bolt 53 to prevent the bolt 53 from rotating when the abutment cylinder 55 rotates.

[0018] The top of the abutment cylinder 55 is provided with a tool docking groove 59. The tool docking groove 59 has a polygonal structure. The tool docking groove 59 enables external tools to quickly dock with the abutment cylinder 55 and drive the abutment cylinder 55 to rotate quickly.

[0019] A protrusion 510 is fixed to the top inner side of the clamping plate 52. The protrusion 510 is engaged with the top edge of the limiting rod 54, and the protrusion 510 achieves a further limiting and locking effect on the limiting rod 54.

[0020] Working principle: When using this pedal motor, first pass the bolt 53 and the limiting rod 54 through the docking hole 4 and insert them into the mounting hole 3, so that the limiting rod 54 is located inside the clamping plate 52. Then, connect the external tool with the tool docking groove 59, and drive the abutment cylinder 55 to rotate, so that the conical structure of the abutment cylinder 55 abuts against the clamping plate 52 and squeezes the clamping plate 52, so that its inner side abuts against the limiting rod 54. After locking the limiting rod 54, connect the locking nut 56 with the bolt 53 to lock the machine housing 1 and the motor housing 2.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
