AI Technical Summary
Existing urea pump protective sleeves have poor cushioning performance, weak low-temperature adaptability, and insufficient sealing, which makes them prone to collapse, cracking due to expansion force, and urea leakage. They are also not compatible with different models of urea pumps.
The design incorporates a main protective module, an elastic buffer module, and quick-release connecting components. The main protective module consists of arc-shaped protective plates spliced into a hollow, elliptical structure, equipped with sealing grooves and seals. The elastic buffer module absorbs vibration and expansion forces through elastic support bars and airbag components. The quick-release connecting components achieve stable locking through snap-fit and elastic buckles.
It achieves effective protection of urea pumps under vibration and low temperature conditions, prevents leakage, enhances structural stability and adaptability, and facilitates quick assembly and disassembly.

Abstract
Claims
1. A urea pump for a protective cover, characterized by: The system includes a main protective module (1), an elastic buffer module (2), and a quick-release connection assembly (3). The main protective module (1) is composed of multiple arc-shaped protective plates (11) spliced together by the quick-release connection assembly (3) to form an elliptical hollow structure. Each arc-shaped protective plate (11) has a sealing groove (12) on its inner side. The elastic buffer module (2) includes elastic support bars (21) distributed along the axis of the main protective module (1) and elastic airbag assemblies (22) symmetrically arranged on both sides of the inner wall of the main protective module (1). The elastic airbag assembly (22) includes an airbag body (221) fixed to the inner wall of the main protective module (1). The airbag body (221) is connected to an inflation / deflation valve (222). The quick-release connection assembly (3) includes a snap-fit protrusion (31) and a snap-fit groove (32) arranged on the side of the arc-shaped protective plate (11) and an elastic latch (33) for locking the spliced state.
2. A urea pump protection sleeve according to claim 1, characterized in that: The sealing groove (12) is provided with a sealing element (121) that is compatible with the arc-shaped protective plate (11).
3. A urea pump protection sleeve according to claim 1, characterized in that: The elastic support strip (21) is fixedly distributed along the inner wall of the main protection module (1), and its extension direction is parallel to the axis of the main protection module (1).
4. A urea pump protection sleeve according to claim 1, characterized in that: The airbag body (221) is fixedly connected to the inner wall of the main protection module (1), and the two elastic airbag components (22) are symmetrically distributed about the axis of the main protection module (1).
5. A urea pump protection sleeve according to claim 1, characterized in that: The inflation / deflation valve (222) extends through the side wall of the main protection module (1) to the outside.
6. A urea pump protection sleeve according to claim 1, characterized in that: The shape of the snap-fit protrusion (31) and the snap-fit groove (32) are adapted to each other. The snap-fit protrusion (31) can be embedded in the corresponding snap-fit groove (32) to form a splice. The elastic buckle (33) is set at the splice of the snap-fit protrusion (31) and the snap-fit groove (32).
7. A urea pump for a protective cover according to claim 6, characterized in that: The snap-fit protrusion (31) and snap-fit groove (32) are inverted trapezoidal structures.
