Description

Technical Field

[0001] This invention belongs to the field of battery swapping equipment for new energy heavy trucks, and in particular, a tipping mechanism for the cargo bed of a new energy heavy truck. Background Technology

[0002] New energy heavy-duty trucks use a battery box for vehicle functions. Existing battery boxes are generally installed at the lower front of the truck bed, with a certain gap between them in the vertical direction. Because the control module, sensor module, and other components of the battery box are all mounted on top, the battery box is susceptible to dust, rain, and snow, which can lead to malfunctions. Summary of the Invention

[0003] In view of the above, it is necessary to provide a new energy heavy truck bed flip-top mechanism and a new energy heavy truck, which aims to provide a cover for the battery box without changing the original vehicle structure. Compared to existing technologies, the aforementioned new energy heavy truck bed flipping mechanism and new energy heavy truck, by setting a tie rod between the cover plate and the vehicle's original telescopic rod, create a space between the cover plate and the truck bed that can cover the top of the battery box when the truck bed is flat, thus protecting the battery box. When the truck bed is raised by the telescopic rod, the tie rod, as the telescopic rod swings with the truck bed, causes the cover plate to flip towards the truck bed, without affecting the battery swapping operation space above the battery box.

[0010] The following detailed embodiments will further illustrate this disclosure in conjunction with the above-described drawings. Detailed Implementation

[0011] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this disclosure; the described embodiments are merely a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0012] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0013] In various embodiments, for ease of description and not limitation of this disclosure, the term "connection" used in the patent application specification and claims is not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0014] like Figure 1-4 The new energy heavy truck includes a vehicle body 10, a truck bed 20, a battery box 30, and a new energy heavy truck bed flip-top mechanism. The vehicle body 10, truck bed 20, and battery box 30 are original components of the new energy heavy truck. The new energy heavy truck bed flip-top mechanism is added to the existing new energy vehicle to cover the top of the battery box 30, preventing rain, snow, and dust from entering from the top of the battery box 30 and damaging it.

[0015] For ease of description, the end along the vehicle's forward direction is the vehicle's front, and the end opposite the front is the vehicle's rear. In this embodiment, the truck bed 20 is rotatably connected to the vehicle body 10 at the rear position via a hinge, and the front is connected to the vehicle body 10 via a telescopic rod 50, which can be a hydraulic rod. During operation, after the telescopic rod 50 extends, it lifts the truck bed 20 from the front; after retracting, the truck bed 20 flips to a position where it rests flat on the vehicle body 10. Furthermore, the top of the truck bed 20 extends outwards to the upper part of the battery box 30.

[0016] Since battery swapping equipment typically connects to the battery box 30 from above, sufficient space needs to be reserved above the battery box 30 for swapping operations. However, this limited space can also allow rain, snow, dust, and other contaminants to enter the top of the battery box 30. Therefore, in this embodiment, the battery box 30 is located at the head of the vehicle body 10 and below the truck bed 20. A new energy heavy-duty truck bed flap mechanism is located between the truck bed 20 and the battery box 30 to cover the top of the battery box 30, thus protecting it.

[0017] The new energy heavy-duty truck bed tipping mechanism includes a cover plate 40 and a tie rod 60. The cover plate 40 is located between the battery box 30 and the truck bed 20. The cover plate 40 is rotatably connected to the vehicle at its front end along the vehicle's travel direction and is located above the vehicle's battery box 30. The rear end of the cover plate 40 along the travel direction overlaps the vehicle. The cover plate 40 is located below the truck bed 20 and its width is greater than the width of the truck bed 20.

[0018] A pull rod 60 connects the telescopic rod 50 and the cover plate 40. One end of the pull rod 60 is rotatably connected to the cover plate 40 at a first connection point, and the other end is rotatably connected to the telescopic rod 50 of the vehicle for raising and lowering the truck bed 20 at a second connection point. The height of the first connection point is greater than that of the second connection point.

[0019] The new energy heavy truck bed tipping mechanism also includes a first connecting seat 61 located on the inner side of the cover plate 40 and a second connecting seat 21 connecting the truck bed 20. The cover plate 40 is hinged to the truck bed 20 via the first connecting seat 61 and the second connecting seat 21. It also includes a third connecting seat 62 located on the inner side of the cover plate 40, and the pull rod 60 is hinged to the truck bed 20 via the third connecting seat 62.

[0020] During operation, the telescopic rod 50 extends and pushes out the truck bed 20. As the truck bed 20 rotates, the telescopic rod 50 also swings. The telescopic rod 50 can then pull the cover plate 40 to rotate in the direction closer to the tail through the pull rod 60, thus avoiding interference with the battery swapping operation space of the battery swapping equipment.

[0021] The aforementioned new energy heavy truck bed flipping mechanism and new energy heavy truck, by setting a pull rod 60 between the cover plate 40 and the vehicle's original telescopic rod 50, when the truck bed 20 is in a flat state, the cover plate 40 and the truck bed 20 form a space that can cover the top of the battery box 30, providing protection for the battery box 30; when the truck bed 20 is raised by the telescopic rod 50, the pull rod 60 drives the cover plate 40 to flip towards the truck bed 20 as the telescopic rod 50 swings with the truck bed 20 being raised, without affecting the battery swapping operation space above the battery box 30.

[0022] In the several specific embodiments provided in this disclosure, it will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be embraced within this disclosure. Furthermore, it is clear that the word "comprising" does not exclude other units or steps, and the singular does not exclude the plural. Terms such as "first," "second," etc., are used to denote names and do not indicate any particular order.
