Description

Technical Field

[0001] The utility model relates to the technical field of automotive auxiliary equipment, specifically a rear - end booster. Background Technique

[0002] In the daily use of large vehicles such as heavy trucks and semi - trailers, large power support is often required during starting, going uphill or under heavy load. Traditional vehicles often have problems such as insufficient power, increased fuel consumption, and aggravated tire wear in these situations. To improve these problems, a variety of auxiliary devices have emerged on the market, but most of them have disadvantages such as complex structure, inconvenient installation, and high maintenance costs. Therefore, it is particularly important to develop a rear - end booster with a simple structure, convenient installation, and remarkable effect.

[0003] The booster with the reference publication number CN216374397U includes a bracket, an adsorbent a, an adsorbent b, and an adsorbent c. The bracket includes a hand - held crossbar, an arc - shaped rod a and an arc - shaped rod b fixedly connected to the hand - held crossbar. One end of the arc - shaped rod a is detachably connected to the adsorbent a. This booster realizes a three - positioning - point structure with the adsorbent a, the adsorbent b, and the adsorbent c respectively provided at the bottom of the bracket. Through three - point positioning, the stability of support and positioning is improved, and it can be well fixed on the rear - end windshield. The two adsorbents a and b on both sides can rotate a certain angle to adapt to the curvature of the windshield by using the sleeve waist - shaped hole mode. The middle adsorbent c can make this booster applicable to spherical or arc - shaped windshields and also play a role in supporting this booster, enabling this booster to bear a greater weight. According to the above, although this booster can be well applied, usually, each component of this booster is fixedly arranged, making it difficult to adjust telescopically according to the usage requirements, and thus difficult to be applied to different scenarios for operation and use, having certain limitations.
