Description

Technical Field

[0001] The present invention relates to the technical field related to automobile chassis battery protection, and in particular to a hybrid automobile chassis battery protection armor. Background Art

[0002] A hybrid vehicle is a vehicle that uses unconventional automotive fuel as a power source, integrates advanced technologies in vehicle power control and driving, and has advanced technical principles, new technologies, and new structures. The battery of a hybrid vehicle is the starting battery for starting the engine, and is an indispensable component of the hybrid vehicle structure. When installing and using the chassis battery of a hybrid vehicle, protective armor is required to assist in use, for example: A new energy vehicle battery protective armor disclosed in publication number CN114142144A clamps the battery body between two shock-absorbing clamping mechanisms. The shock-absorbing clamping mechanisms are deformed by external impact and clamp the battery body at the same time, and release potential energy to the buffer mechanisms connected to the two ends. The protective armor has good shock-absorbing and buffering effects, can flexibly resist external impacts from all directions, and the protective performance is greatly improved. The above device uses the shock-absorbing clamping mechanism to treat the shock-absorbing effect of the battery body. However, in actual work, after the battery body is clamped by the clamping mechanism, the heat is only dissipated by the battery body's own properties, and the effect is still relatively poor. However, when used in combination with a fan, the heat circulation effect is poor due to the close clamping. Another example is the protective assembly for electric vehicle batteries disclosed in the publication number CN211789149U. When the protective assembly is assembled, an upper protective member, an electric vehicle battery, a lower protective member and a battery box are sequentially arranged from top to bottom. The battery box is used to accommodate the electric vehicle battery, and the electric vehicle battery is sandwiched between the lower protective member and the upper protective member in the up-down direction, so that the protective assembly can protect the battery and the electric vehicle. In addition, when the battery itself produces a fire or explosion due to thermal runaway, for example, the protective assembly can prevent the fire or explosion from being transmitted to the outside of the battery within a certain period of time, causing harm to other components of the electric vehicle. However, when the above device is assembled, there are other problems. First, when docking, the upper protective assembly and the lower protective assembly are used in combination to protect the battery. However, when the protective device is docked during use, it is only used for one type of battery. When other batteries are used, the upper protective assembly and the lower protective assembly need to be replaced. Therefore, there are still certain deficiencies when assembling.

[0003] Therefore, we proposed a hybrid vehicle chassis battery protection armor to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a hybrid vehicle chassis battery protection armor to solve the problem proposed in the above background technology that the battery protection armor currently on the market uses a shock-absorbing clamping mechanism to treat the battery body with a shock-absorbing effect. However, in actual work, after the battery body is clamped by the clamping mechanism, the heat is only dissipated by the battery body's own properties, and the effect is still relatively poor. However, when used in combination with a fan, the heat circulation effect is poor due to the close clamping. In addition, when docking, the upper protection component and the lower protection component are used together to protect the battery. However, when the protective device is used for docking, it is only used for one type of battery. When other batteries are used, the upper protection component and the lower protection component need to be replaced. Therefore, there are still certain deficiencies during assembly.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: A hybrid vehicle chassis battery protection armor, comprising a battery body, wherein the top of the battery body is provided with a plurality of wiring holes for easy connection; Also includes: Side wall protection plates, two groups of side wall protection plates are arranged at the left and right sides of the top of the bottom protection plate, main protection plates are arranged at the front and rear sides of the top of the bottom protection plate, and heat dissipation plates are arranged at the outer sides of the side wall protection plates to facilitate heat dissipation; The side wall protection plate and the main protection plate are assembled by a splicing frame, the splicing frame is fixed to the top position of the bottom protection plate by bolts, and four groups of splicing frames are provided, the outer side of the splicing frame is provided with a first slide groove and a second slide groove, and the side wall protection plate and the main protection plate are fixed with a first clip strip and a second clip strip; A splicing frame is provided with a set of fixing plates fixed at the bottom of the splicing frame, and a lifting frame designed above the fixing plates is fitted to the bottom side of the battery body, and there is a height gap between the fixing plates and the lifting frame.

[0009] As a preferred technical solution of the present application, a limiting card slot is provided on one side of the surface of the first card strip and the second card strip, and the limiting card slot forms a locking mechanism with the interior of the splicing frame through a limiting card column. The limiting card column extends into the interior of the limiting card slot, thereby ensuring that the first card strip and the first slide groove are limited.

[0013] As a preferred technical solution of the present application, both ends of the guide rod are fixed in grooves opened inside the splicing frame, and the outer side of the lifting frame extends out of the splicing frame to act on the bottom of the battery body, allowing the lifting frame to slide on the outer side of the guide rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the hybrid vehicle chassis battery protection armor is provided with a side wall protection plate, and convex points are provided on both the front and rear sides of the side wall protection plate and the main protection plate to reduce the contact area with the surface of the battery body, and ensure the rotation of the driving fan inside the battery body to perform heat dissipation treatment.

When the second extrusion plate descends, the two sets of matching racks fixed at the bottom of the second extrusion plate will drive the meshing connecting gears to rotate through the rotating rod, so that the movable racks can be raised, and the lifting frame can be raised through the guide rod, thereby ensuring the gap between the battery body and the lifting frame, and facilitating the circulation of gas. Furthermore, a main protective plate is provided, and an anti-collision strip is provided on the outer side of the main protective plate to protect the battery body.

[0015] 2. A rotating sleeve is provided. By rotating the rotating sleeve, the threaded rod of the rotating sleeve can be moved, so that the first extrusion plate and the second extrusion plate move inside the splicing frame. The horizontal plate is extruded by the movement of the first extrusion plate and the second extrusion plate, and the limit card column is driven by the horizontal plate to limit the position. The limit card column limits the limit card slot to prevent the side wall protection plate and the main protection plate from loosening; Furthermore, a first clamping strip and a first slide groove are provided. The length of the first clamping strip and the first slide groove is greater than the width of the side wall protection plate and the main protection plate. When the size of the battery body is too long, the side wall protection plate and the main protection plate are turned around for assembly, which can adapt to battery bodies of various sizes.
