Based on the above design concept, an exemplary structure of the protection device of the present embodiment is shown in fig. 4, wherein the protection cover 1 is box-shaped, and an opening of the protection cover is disposed downward to cover the battery pack body therein, so as to achieve a protection effect. Of course, according to the requirement of the electric quantity output of the battery pack body, a through hole for the wiring harness to pass through can be further formed on the side surface of the protective cover 1 according to the specific use requirement in the embodiment. In the embodiment, in order to facilitate the installation of the protective cover 1 on the vehicle body 4, the vertical plate 3 is further fixedly installed on the vehicle body 4, and the side surface of the protective cover 1 is installed on the vertical plate 3 through the insertion assembly and the positioning assembly. Here, the upright plate 3 has a simple structure, and the protection cover 1 can be conveniently mounted on the vehicle body 4.
In this embodiment, the socket is a slot formed on the vertical plate 3, and the insertion portion is an insertion block 2 formed on the side surface of the protection cover 1. The slots and the inserting blocks 2 are simple in structure and convenient to fix on the vertical plate 3 and the protective cover 1. In a specific structure, as shown in fig. 5, two outward turning plates 303 with an outward skimming function are arranged on the vertical plate 3, the two outward turning plates 303 extend along the height direction of the vertical plate 3, and the slot is formed by enclosing the two outward turning plates 303 and the vertical plate 3. Here, through setting up outer board 303 that turns over, not only can lead the cartridge of inserted block 2 in the slot, still can prevent effectively that inserted block 2 from deviating from in the slot. The outward turning plate 303 and the vertical plate 3 in this embodiment are integrally formed, for example, both the outward turning plates 303 are formed by stamping, and due to the forming of the outward turning plate 303, a punching hole 301 is further formed on the vertical plate 3. And the two outer turning plates 303 are arranged in a splayed manner. In this embodiment, the outward turning plate 303 and the vertical plate 3 are integrally formed, so that the strength of the vertical plate 3 can be significantly improved. In addition, in this embodiment, the top of the insertion block 2 is configured with the lapping boss 204 capable of lapping on the tops of the two outward turned edges to limit the insertion block 2 in the insertion process, and the insertion block is simple in structure and good in use effect.
The positioning portion in this embodiment is an elastic piece 302 fixedly connected to the vertical plate 3 and having a clamp head 3021 formed on the vertical plate 3, and the specific structure is shown in fig. 5, in order to avoid the structure of the elastic piece 302 affecting the insertion of the protective cover 1 into the slot, a through hole 304 is formed in the middle of the two outer turning plates 303, and the top end of the elastic piece 302 is fixedly connected to the upper side edge of the through hole 304 and can be placed in the through hole 304. As shown in fig. 2 and fig. 5, the above-mentioned clamp 3021 is formed by bending the free end of the elastic piece 302 away from the direction of the protection mask 1, so that the elastic piece 302 can be elastically deformed in the through hole 304 due to the insertion of the insertion block 2, and can be tightly abutted to the matching portion of the protection mask 1 due to the elastic retraction of the following clamping groove 202 in place, thereby positioning the protection mask 1. In addition, the elastic piece 302 and the vertical plate 3 are integrally formed, so as to improve the structural strength of the elastic piece 302.
Referring to fig. 6, the positioning and matching portion in this embodiment is a slot 202 formed on the insert block 2 corresponding to the elastic piece 302, specifically, as shown in fig. 7 and 9, the slot 202 has a cross-sectional shape of ">", and the clamp 3021 of the elastic piece 302 can be tightly clamped in the slot 202 to position the insert block 2, thereby realizing the clamping and positioning of the inserted shield 1. Further, a guide surface 203 inclined toward the upright plate 3 is provided at the bottom end of the insert block 2 so that the attached chuck 3021 can be smoothly inserted into the card slot 202. Here, the guide surface 203 improves the insertion effect of the insertion block 2, and has a simple structure and a good guide effect. In addition, still be provided with a plurality of lightening grooves 201 on inserted block 2, so set up, can alleviate protector's weight, and then reduction in production cost. In addition, the vertical plate 3 in this embodiment may be one instead of two, which are separately disposed on two opposite sides of the protection cover 1 in the figure, however, the number of the insertion components and the positioning components should match the number of the vertical plates 3.
When the plug-in mounting assembly and the positioning assembly are used, the bottom ends of the blocks are placed in the slots firstly, and the blocks slide downwards through the guide surfaces on the plug-in blocks 2. Then, with the insertion of the plug 2, the collet 3021 on the elastic piece 302 is pressed by the plug 2 to bend toward the inside of the through hole 304, and when the card slot 202 is positioned close to the collet 3021, the collet 3021 on the elastic piece 302 may bend toward the card slot 202. Finally, the clamp head 3021 is tightly abutted to the clamp groove 202, and the lap joint boss 204 on the insert block 2 is abutted to the outward turning plate 303 of the insert groove, so that the protective cover 1 is fixedly mounted on the vertical plate 3. The state after the installation is completed is still as shown in fig. 7 and 8.
When the protective cover 1 needs to be repaired and disassembled, the clamp head 3021 on the elastic sheet 302 can be removed from the clamp groove 202 by a repair tool such as a straight screwdriver, and then the protective cover 1 is pulled out from the clamp groove along the height direction of the protective cover 1, so that the protective cover 1 is separated from the vehicle body 4.
The portable battery replacement electric vehicle power battery pack supporting structure in the embodiment can install the protection cover 1 on the vehicle body 4 in a plug-in mounting mode through the plug-in mounting assembly, and supports the tight positioning of the protection cover 1 after the plug-in mounting through the positioning assembly, so that the protection cover 1 can be conveniently installed and disassembled, and meanwhile, through the support tight positioning of the positioning assembly, the vibration force applied to the protection cover 1 can be absorbed, and the stability of the protection cover 1 in working can be improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
