Description

Technical Field

[0001] This utility model belongs to the field of jack technology, specifically relating to an electric horizontal jack. Background Technology

[0002] With the upgrading of automotive aftermarket services and the rapid growth in demand for new energy vehicle repair, traditional manual mechanical horizontal jacks can no longer meet the needs of modern users in terms of efficiency, safety, and ease of use. Against this backdrop, electric horizontal jacks, with their advantages of automated lifting, labor-saving operation, and rapid response, are gradually replacing manual products and becoming the mainstream tool in automotive repair, 4S shops, roadside assistance services, and home garages. The industry as a whole is showing a clear trend towards electrification, intelligence, and modularization.

[0003] In recent years, domestic and foreign manufacturers have launched various electric jack products, continuously innovating in terms of drive methods, structural compactness, and human-machine interaction, significantly improving operational safety and user experience. Meanwhile, the industry generally uses rechargeable lithium batteries as the power source. However, existing electric horizontal jacks still have significant design flaws in their power system layout. Most products directly install the battery pack on or near the operating handle, aiming for the convenience of "integrated grip + power supply." Although this design seems compact, it exposes the following prominent problems in actual use: First, it leads to an unbalanced center of gravity, affecting stability. The horizontal jack body has a low, flat structure, requiring good ground contact and anti-tipping ability during operation. Placing the heavy battery pack at the high handle position causes the overall center of gravity to shift upwards and forwards, easily causing swaying or even tipping over, posing a safety hazard. Second, the user experience is poor. The battery pack increases the diameter and weight of the handle, making it difficult for users to grip, especially in scenarios requiring prolonged operation or frequent position adjustments, significantly increasing operator fatigue.

[0004] In summary, the inherent defects in the battery pack layout of existing electric horizontal jacks restrict their further improvement in safety, reliability, and user experience.

[0005] In view of the aforementioned problems, it is necessary to design an electric horizontal jack that can avoid the impact of the battery pack on stability and operability. To this end, the applicant has ingeniously designed this technical solution. Utility Model Content
