Description

Technical Field

[0001] The utility model relates to the field of fuel cells, and more specifically to a fuel cell heavy truck auxiliary device. Background Art

[0002] Hydrogen commercial vehicles usually have a voltage of 24V, and low-voltage batteries are usually 12V. The low-voltage electrical appliances of the entire vehicle require 24V. It is a better solution to achieve 24V by connecting 12V batteries in series. However, the batteries of hydrogen heavy trucks are often large and heavy. When fixing them, a support seat structure is set on the outside of the battery to cooperate with the bracket structure to achieve installation and fixation. For example, the Chinese utility model with application number 202121059915.1 proposes a battery fixing bracket for fuel cell hydrogen heavy trucks. When the device is in use, after the two batteries are placed in the base, the fixing parts are installed on the upper ends of the two fixing plates and fixed. The battery can be fixed in the bracket body, and then the bracket body is fixed to the body of the hydrogen heavy truck through multiple mounting parts.

[0003] When the above-mentioned fixing bracket device is used, there are the following problems:

[0004] It only has a basic fixing effect, and cannot provide good buffering protection for the battery after it is fixed. At the same time, when fixing, the battery can only be fixed by vertical covering and fixing the fixing parts at the upper position. When the battery itself is on the base, it has no fixing or limiting effect, and the fixing effect needs to be improved. At the same time, the fixing parts are set in a rectangular shape, and can only contact and fix with one side of the top of the battery. The contact range is small and the fixing effect is not good.

[0005] Therefore, the utility model proposes a fuel cell heavy truck auxiliary device. Utility Model Content

[0027] The following will be combined with the attached embodiment of the present utility model Figure 1-Figure 5 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0028] See also Figure 1-5 In an embodiment of the utility model, a fuel cell heavy truck auxiliary device includes a base 1 and side panels 2 on both sides thereof in the horizontal direction and a baffle 4 on one side thereof in the longitudinal direction. An upper fixing structure 3 is fixedly connected to the top of the side panel 2, and the upper fixing structure 3 is also located on the outside of the base 1. An inner limiting structure 5 is fixedly connected to the center of the surface of the base 1. Both side surfaces of the base 1 are fixedly connected to inner supporting structures 6. The side panels 2 and the baffle 4 are vertically raised along the edges of the base 1, and strip grooves are provided on the surface of the side panel 2.

[0029] In the embodiment of the utility model, the upper fixed structure 3 includes a matching upper fixed frame 7 and a telescopic rod 11 connected horizontally to its inner side, both ends of the telescopic rod 11 are fixedly connected with a fixing head 12 arranged inwardly in an "L" shape, and both sides of the surface of the upper fixed frame 7 are penetrated with a limit rod 9 protruding inward, and both ends of the upper fixed frame 7 are fixedly connected with a mounting head 10 protruding inward, and the inner side of the end corner of the upper fixed frame 7 is fixedly connected with a fixing seat 8. The upper fixed frame 7 is arranged in a triangular frame as a whole, and both ends are fixedly connected to the side plate 2 through the mounting head 10. The mounting head 10 is also embedded in the groove opened on the surface of the side plate 2. The limit rod 9 is evenly distributed in multiple groups along both sides of the upper fixed frame 7, and the inner end of the limit rod 9 is also matched with a damping pad. The mounting head 10 is used to achieve the effect of connecting and fixing the upper fixed structure 3 as a whole to the side plate 2, and the limit rod 9 on the surface of the triangular upper fixed frame 7 is used to press down and fix the battery placed on the inner side of the base 1 from the outer side.

[0030] The user embeds the installation head 10 into the groove on the surface of the side panel 2 and fixes the two with external screws. At this time, the connection and installation of the upper fixing frame 7 are completed. The two ends of the triangular upper fixing frame 7 are inclined in a plane, and the limiting rod 9 on the matching surface contacts the battery surface, which can effectively ensure the contact range with the battery surface, and then ensure the fixing effect of the battery. At the same time, the damping pad arranged at the inner end of the limiting rod 9 can reduce the vibration generated by the external battery.
