Description

Technical Field

[0001] The utility model relates to the technical field of battery compartment installation and fixation, and particularly relates to a front-mounted installation structure of an assembled battery compartment for a hybrid vehicle. Background Art

[0002] In the road transportation industry, semi-trailers have always held an unshakable position, mainly used for transporting large-sized and difficult-to-dismantle goods. According to their different transportation functions, they can be divided into various models of vehicles, such as dump semi-trailers, low-bed semi-trailers, flatbed semi-trailers, container semi-trailers, etc. Among them, dump semi-trailers also include side-tipping trailers, rear-tipping trailers, etc. With the research and innovation of new energy, the above-mentioned various semi-trailers have all evolved into hybrid systems, with energy storage batteries installed in their body frames, which can quickly recover the braking kinetic energy during braking when the vehicle is running to form electric energy, and then use the electric energy as kinetic energy to assist the vehicle to move forward when going uphill or starting, so as to achieve the effect of fuel saving. However, the body of the rear-tipping trailer is relatively short, and there are many devices to be arranged on the frame, so there is no space in the middle of the frame for installing the battery compartment. At the same time, considering the weight distribution balance ratio in the total frame, it is necessary to set the energy storage battery at the front end of the frame. Therefore, a fixing structure is required for adaptive installation. The existing installation of the battery compartment usually directly welds the bracket to the body girder, which is prone to welding deformation, and the stress at the welding point is strong and easy to break, posing certain potential safety hazards.

[0028] The following further elaborates in detail on the specific implementation manners of the present utility model with reference to the drawings:

[0029] As Figure 1 and Figure 2 shown, an assembled front-mounted battery compartment structure for a hybrid vehicle is applied to a rear-tipping semi-trailer equipped with a hybrid system and is arranged at the front end of the gooseneck frame in the semi-trailer body frame. A front end plate 5 is fixedly installed at the front end of the main beam 1 in the semi-trailer gooseneck frame. With reference to Figure 3 shown, the front-mounted battery compartment structure 3 has two layers, including a battery compartment bracket 31, multiple vertical fixing columns 32 fixed above the battery compartment bracket 31, multiple support cross beams 33, and multiple supporting longitudinal beams 34. Among them, the battery compartment bracket 31 is used as the first-layer fixing structure and includes three mutually spaced and parallel support main beams 311 with their upper ends flush. The orthographic projection of each support main beam 311 is trapezoidal, narrower in the front and wider in the rear, and is made of U-shaped plates. An installation plate 312 is also fixedly installed at the rear end of the support main beam 311, perpendicular to the support main beam 311. Connection bolt holes are provided on the installation plate 312, and a reinforcing rib plate 314 is added between the installation plate 312 and the support main beam 311 to enhance the overall strength. The rear ends of the three support main beams 311 are all detachably and fixedly connected through bolts passing through the connection bolt holes on the installation plate 312 and the above-mentioned front end plate 5 and cooperating with corresponding nuts. Elastic washers are also sleeved on the corresponding bolts to prevent loosening due to vibration. The front ends of the three support main beams 311 are fixed by a secondary beam 313 to enhance the stability strength of the entire battery compartment bracket 31.

[0030] At the upper end surface of each of the above-mentioned support main beams 311, two vertical fixed columns 32 are welded and fixed. The two vertical fixed columns 32 both extend vertically upward perpendicular to the upper end surface of the support main beam 311, and the distance between the two is greater than the width of the battery compartment 2; on the side wall of the upper half of each vertical fixed column 32, two positioning and fixing holes are provided. A support cross beam 33 is erected between the two vertical fixed columns 32. Refer to Figure 4 As shown, the support cross beam 33 is an L-shaped plate, installed with the opening facing downwards. The two ends of its vertical plate are widened to increase the connection contact area. Connection holes corresponding to the above-mentioned positioning and fixing holes are provided on the widened vertical plate. The support cross beam 33 is detachably and fixedly connected to the vertical fixed column 32 through bolts passing through the connection holes and the positioning and fixing holes. The setting height of the lowermost positioning and fixing hole on the above-mentioned vertical fixed column 32 is greater than the height of a single-layer battery compartment 2. The three support cross beams 33 are fixedly installed flush on the corresponding vertical fixed columns 32 to form a second-layer battery compartment fixed installation structure.

[0031] Two supporting longitudinal beams 34 are installed across the three support main beams 311 and the three support cross beams 33. The two supporting longitudinal beams 34 are arranged at intervals, and their widths are the same as the width of the battery compartment 2; as Figure 5 shown, each supporting longitudinal beam 34 is selected as an L-shaped angle iron structure, and is fixedly installed with the opening facing upwards on the corresponding support main beam 311 or support cross beam 33. A connection through hole 37 for connecting and fixing the battery compartment 2 is provided on its bottom plate.

[0032] Combined with Figures 6 to 8 As shown, an outer cover 4 is also sleeved outside the above-mentioned battery compartment front installation structure 3. The outer cover 4 is a cavity structure formed by splicing multiple outer cover plates with rivets. At the same time, in order to increase its stability and strength, multiple arc-shaped reinforcing ribs 41 arranged along its curvature are fixedly provided on its inner side wall. Installation frames 42 are respectively fixedly installed on the inner sides of the front cover plate and the rear cover plate of the outer cover 4 for connection and fixation after the outer cover 4 is installed. Correspondingly, installation through holes 35 are provided on the side walls of the above-mentioned vertical fixed columns 32. When the outer cover 4 is sleeved outside the battery compartment installation structure, the outer cover 4 is connected and fixed to the front installation structure 3 by bolts passing through the corresponding installation frames 42 and the installation through holes; at the same time, in order to increase the installation stability of the outer cover 4, the lower end of the front cover plate of the outer cover 4 is bent inwards, and multiple bolt through holes 43 are provided on it. Correspondingly, multiple bolt holes are provided on the upper end surface of the above-mentioned auxiliary beam 313, and the fixation between the two is completed through the cooperation of bolts and nuts.

[0033] In order to strengthen the ventilation and heat dissipation of the energy storage battery, ventilation windows are provided on the front cover plate, left cover plate and right cover plate of the above-mentioned outer cover 4, and filter nets are installed on each ventilation window.

[0034] As a further optimized technical solution of the present utility model, in order to adapt to battery compartments 2 of different sizes and models, the above-mentioned supporting longitudinal beams 34 can be slidably adjusted and fixed relative to the supporting main beam 311 or the supporting cross beam 33, avoiding the need for disassembly and replacement each time. Refer to Figure 9 As shown, a plurality of guide plates 38 are fixedly provided below the bottom plate of the supporting longitudinal beam 34. The guide plates 38 are perpendicular to the supporting longitudinal beam 34. Every two adjacent guide plates 38 form a group, and the distance between the two guide plates 38 in the same group is equal to the width of the upper top plate of the supporting cross beam 33, which can define the synchronous sliding direction of the supporting longitudinal beam 34 and prevent deviation. Correspondingly, a plurality of positioning holes are provided on the supporting cross beam 33. When the two supporting longitudinal beams 34 are adjusted to the width of the battery compartment 2, the supporting longitudinal beam 34 and the supporting cross beam 33 are relatively fixed by positioning bolts.

[0035] Furthermore, when the battery compartment 2 is placed and fixed on the supporting longitudinal beam 34, the installation position of the battery compartment 2 is such that the side wall of the battery compartment 2 cannot be in contact with the side vertical fixing column 32. Therefore, a jack is provided on the side wall of the vertical fixing column 32 facing the battery compartment 2. A resilient screw is installed through the jack. An end plate is fixedly installed at the inner end of the resilient screw close to the battery compartment 2. A spring is sleeved on the resilient screw, and the spring is placed between the end plate and the vertical fixing column 32. At the same time, a thread is provided on the outer side of the outer end of the resilient screw, and a matching fastening nut is sleeved; a rubber elastic sheet is installed on the side of the end plate facing the battery compartment 2. The end plate is pressed against the side wall of the battery compartment 2 by the elastic force of the spring, squeezing and fixing the outside of the battery compartment 2 to achieve the purpose of ensuring the stable placement of the battery compartment 2 and offsetting the possible shaking of the battery compartment 2 during vehicle operation. The operation is simple and convenient.

[0036] The above-mentioned front-mounted installation structure 3 of the battery compartment can be provided with multiple layers according to actual installation requirements. Among them, the height of the vertical fixing column 32 can be replaced according to requirements, and the number of positioning and fixing holes provided on each vertical fixing column 32 is also correspondingly increased. The interval distance between two adjacent groups of positioning and fixing holes is slightly larger than the height of the battery compartment 2, which is convenient for the installation and fixing of the supporting cross beam 33. The structure of each layer is the same and is fixed by bolts, which is convenient for assembly and disassembly.
