Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, specifically a locking drive mechanism and an ignition switch assembly. Background Technology

[0002] In the field of motorcycle ignition switch assemblies, current locking mechanisms primarily employ a pin-shaft mechanism, where the pin disengages from or inserts into a pin slot, to unlock or lock the lock cylinder, as illustrated in the ignition switch lock disclosed in application number CN201822079043.X. The pin-shaft's actuation mainly relies on electromagnetic drive mechanisms or solenoid valves. However, electromagnetic drive mechanisms have numerous drawbacks. Their extremely complex structural design not only requires significant investment of manpower, resources, and time in manufacturing but also increases the probability of malfunctions. Once a malfunction occurs, repairs are difficult, further increasing operating costs. Solenoid valve actuation also suffers from high costs, which to some extent limits the overall cost-effectiveness of motorcycles.

[0003] Given the shortcomings of the existing technologies, developing a locking drive mechanism that is simple in structure, low in cost, and has a good modular design is of great practical significance. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a locking drive mechanism and an ignition switch assembly.

[0005] The technical solution adopted by this utility model is: a locking drive mechanism, comprising:

[0006] A base plate, wherein a shaft hole is provided on the base plate;

[0007] A cover body, wherein the base plate is fitted onto the cover body, and an installation cavity is formed between the base plate and the cover body;

[0008] An electric motor is fixedly installed in the aforementioned mounting cavity, and an output gear is fixedly installed on the output shaft of the motor.

[0009] The telescopic rod passes through the aforementioned shaft hole and engages with the shaft hole for telescopic cooperation. The end of the telescopic rod is provided with a driving tooth surface, which meshes with the output gear for transmission.

[0010] Furthermore, the bottom plate is provided with a boss on one side of the cover that can be embedded into the mounting cavity, and the cover is provided with a side step that abuts against one end of the bottom plate. Both the cover and the bottom plate are provided with fixing holes.

[0011] Furthermore, there is one fixing hole.

[0012] Furthermore, a mounting plate is provided on the side of the cover, and mounting holes are provided on the mounting plate.

[0014] Furthermore, a drive block is fixed to the end of the telescopic rod, and the drive tooth surface is disposed on the side of the drive block.

[0015] Furthermore, it also includes an upper spring and a lower spring, the upper spring being used to apply a downward elastic force to the telescopic rod, and the lower spring being used to apply an upward elastic force to the telescopic rod.

[0016] Furthermore, one end of the upper spring is connected to the top wall of the mounting cavity, and the other end is connected to the spring groove on the top of the drive block. The lower spring is fitted onto the telescopic rod, and one end of the lower spring abuts against the bottom surface of the drive block, while the other end abuts against the bottom plate.

After the locking drive mechanism is fixed to the assembly housing, the telescopic rod of the locking drive mechanism extends into the pin hole and connects with the pin.

[0018] The beneficial effects of this utility model are:

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0032] This utility model provides a locking drive mechanism.

[0033] In this embodiment, refer to Figure 1-5 The locking drive mechanism includes:

[0034] Base plate 1, wherein a shaft hole 2 is provided on the base plate 1;

[0035] The cover body 3, the bottom plate 3 is fitted onto the cover body, and the bottom plate and the cover body form an installation cavity 4;

[0036] Motor 5, the motor 5 is fixedly installed in the above-mentioned mounting cavity 4, and an output gear 6 is fixedly installed on the output shaft of the motor;

[0037] Telescopic rod 7 passes through the aforementioned shaft hole and engages with the shaft hole for telescopic cooperation. The end of the telescopic rod is provided with a drive tooth surface 8, which meshes with the output gear for transmission.

[0038] In the above technical solution, a shaft hole is provided on the base plate to form a mounting cavity with the cover. The motor is fixed inside the cavity, and an output gear is connected to the output shaft. The telescopic rod passes through the shaft hole, and the drive tooth surface on its end meshes with the output gear. When the motor runs, the output gear rotates, driving the telescopic rod to extend and retract along the shaft hole through meshing, thus realizing the driving function. The entire drive mechanism is designed as a whole, using a modular design, which reduces costs and is easier to implement compared to traditional electromagnetic drives.

[0039] Specifically, the bottom plate is provided with a boss 9 on one side of the cover that can be embedded into the mounting cavity, and the cover is provided with a side step 10 that abuts against one end of the bottom plate. Both the cover and the bottom plate are provided with fixing holes 11.

[0040] In this embodiment, a boss on one side of the base plate is embedded in the mounting cavity, and a side step on one side of the cover abuts against one end of the base plate. The two are fixed together by fixing holes. The boss and the mounting cavity work together to enhance structural stability, the side step restricts the displacement of the base plate, and the fixing holes are used to install fasteners (such as bolts) to secure the base plate and the cover. This optimizes the connection method between the base plate and the cover, improves the stability and reliability of the overall structure, reduces the risk of component loosening under vibration and other operating conditions, and extends the service life of the mechanism.

[0041] Specifically, there is one fixing hole.

[0042] In this embodiment, based on the limiting effect of the boss and the side step, the bottom plate and the cover can be stably connected through a single fixing hole, which reduces the number of parts, lowers production and processing costs, and reduces assembly errors that may be caused by multiple fixing holes, thereby improving assembly efficiency.

[0043] Specifically, the side of the cover is provided with a mounting plate 12, and the mounting plate 12 is provided with mounting holes 13.

[0044] In this embodiment, the mounting plate on the side of the cover has mounting holes for mounting the entire locking drive mechanism onto other components (such as the ignition switch assembly housing). The mechanism is securely installed by engaging the mounting holes with corresponding connectors (such as screws).

[0045] Specifically, the motor has positioning cut surfaces 14 on both sides, and the mounting cavity has positioning surfaces 15 on both sides that fit with the positioning cut surfaces.

[0046] In this embodiment, the positioning cut surfaces on both sides of the motor fit snugly against the positioning surfaces on both sides of the mounting cavity. During motor installation, the positioning cut surfaces mate with the positioning surfaces to accurately determine the motor's position, preventing the motor from shifting or rotating within the mounting cavity. No bolts are required for fixing, further simplifying the structure and reducing costs.

[0047] Specifically, a drive block 16 is fixed to the end of the telescopic rod, and the drive tooth surface is disposed on the side of the drive block.

[0048] In this embodiment, a drive block is fixed to the end of the telescopic rod, and the drive teeth are on the side of the drive block. When the motor drives the telescopic rod to extend or retract, the telescopic rod drives the drive block to move, and the teeth on the drive block mesh with the output gear to transmit power.

[0049] Specifically, it also includes an upper spring 17 and a lower spring 18. The upper spring is used to apply a downward elastic force to the telescopic rod, and the lower spring is used to apply an upward elastic force to the telescopic rod. One end of the upper spring is connected to the top wall of the mounting cavity, and the other end is connected to the spring groove 19 on the top of the drive block. The lower spring is fitted onto the telescopic rod, and one end of the lower spring abuts against the bottom surface of the drive block, and the other end abuts against the bottom plate.

[0050] In this embodiment, the upper and lower springs apply opposing elastic forces to the telescopic rod. One end of the upper spring is connected to the top wall of the mounting cavity, and the other end is connected to the spring groove on the top of the drive block; the lower spring is fitted onto the telescopic rod, with its two ends abutting against the bottom surface of the drive block and the base plate, respectively. The spring force keeps the telescopic rod in a specific position when stationary and also acts as a buffer and reset mechanism during motor drive, resulting in high mechanism efficiency and stability.

[0051] This application also provides an ignition switch assembly, including an assembly housing 20, a pin, and a locking drive mechanism as described in any of the above claims. The assembly housing is provided with a pin hole 21 corresponding to the pin. After the locking drive mechanism is fixed to the assembly housing, the telescopic rod of the locking drive mechanism extends into the pin hole and connects with the pin.

[0052] In this embodiment, the ignition switch assembly includes an assembly housing, a pin, and a locking drive mechanism. The locking drive mechanism is fixed to the assembly housing, and a telescopic rod extends into the pin hole and connects to the pin. A motor drives the telescopic rod to extend and retract, thereby moving the pin within the pin hole to unlock and lock the ignition switch. Applying the locking drive mechanism to the ignition switch assembly solves the problems of traditional pin-driven ignition switches, improves the reliability and maintainability of the ignition switch assembly, reduces costs, and provides a better solution for motorcycle ignition systems.

[0053] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
