Description

Technical Field

[0001] The utility model relates to the field of automobile anti-theft locks, in particular to an automobile pedal lock with good anti-pry performance. Background Art

[0002] In recent years, with the rapid development of the automotive industry and the socio-economic landscape, the number of cars in urban areas has increased, and the phenomenon of car theft has become increasingly serious. This has not only disrupted public order but also caused significant distress to numerous car owners. Consequently, a wide variety of car theft prevention products have flooded the market, including steering wheel locks that lock the steering wheel, anti-theft devices with electronic voice-activated alarms, and pedal locks. However, these steering wheel locks primarily utilize locks that hook onto the steering wheel at both ends. These locks offer extremely poor anti-theft performance, allowing thieves to quickly saw through the steering wheel or forcefully pry open the exposed lock head, rendering the lock's anti-theft function ineffective. Anti-theft devices with electronic voice-activated alarms are prone to generating noise that disturbs residents, making them unsuitable for market promotion. Pedal locks, on the other hand, offer numerous advantages, including structural strength, concealed design, and resistance to prying, thus securing the vehicle against theft by restricting the use of the brake, accelerator, or clutch pedals. These pedal locks offer numerous advantages, including high structural strength, a discreet design, and resistance to prying, making them highly popular.

[0003] However, although the existing automobile pedal lock structures on the market can provide consumers with basic anti-theft needs and are indeed progressive, in actual use, it is found that they still have many shortcomings in their own structure and performance. In particular, the opening of the clamp arm limit slot is too large and the structural strength is low. As a result, the hook of the inner telescopic component has a chance of falling out of the limit slot under the action of external force, resulting in a significant reduction in anti-theft performance.
