It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Please refer to Figures 1 - 4 , a low-voltage automotive starting power supply housing, comprising:

[0030] A bottom shell 100, an outer extension part 110 and an inner extension part 130 extending upward are provided at the open end of the bottom shell 100, a groove 140 is formed between the outer extension part 110 and the inner extension part 130, several snap plates 120 extend from the outer extension part 110, and several first snap parts 121 are provided on the snap plates 120;

[0031] A top cover 200, a nesting part 210 extending into the groove 140 is provided on the top cover 200, the nesting part 210 is adhesively connected to the bottom shell 100 through the groove 140, several second snap parts 220 are arranged near the nesting part 210 on the top cover 200, and the first snap parts 121 are snap-connected to the second snap parts 220.

[0032] The outer extension part 110 and the inner extension part 130 of the bottom shell 100 form a groove 140, the top cover 200 is nested with the groove 140 and adhesively connected through a sealant. The groove 140 can facilitate the storage of the sealant, and the first snap parts 121 on the snap plate are snap-connected to the second snap parts 220 on the top cover 200, so that the bottom shell 100 and the top cover 200 form a fast and stable connection, which is convenient to operate and has low cost.

[0033] Please refer to Figure 1 and Figure 2 , side extension parts 150 extending to the left and right are provided at the open end of the bottom shell 100, and diagonal braces 151 are provided between the side extension parts 150 and the side walls of the bottom shell 100. The setting of the side extension parts 150 can increase the width of the top cover 200 to facilitate the installation of components such as circuit boards in the top cover 200.

[0034] Please refer to Figures 1 - 3, honeycomb-shaped reinforcing rib groups 160 are provided on the front and rear surfaces of the bottom shell 100. By setting the reinforcing rib groups 160, while reducing the weight of the outer shell, the strength of the bottom shell 100 is ensured, heat dissipation is enhanced, and a shock-absorbing function is provided, which can better protect the power supply inside the bottom shell 100. Particularly, thinning grooves are provided on the front and rear surfaces of the bottom shell 100, and the reinforcing rib groups 160 are located in the thinning grooves and are connected to the convex walls forming the thinning grooves. Particularly, a nameplate area 162 is also provided on the front surface of the bottom shell 100. A LOGO can be formed in the nameplate area 162 or attached by bonding. The nameplate area 162 is located in the thinning groove. One side of the nameplate area 162 is connected to the convex wall of the thinning groove, and the other three sides are surrounded and connected by the reinforcing rib groups 160. Or, the nameplate area 162 is located in the middle of the thinning groove and is surrounded and connected by the reinforcing rib groups 160 on all sides.

[0035] Please refer to Figures 1 - 3 , the reinforcing rib groups 160 are composed of several regular polygon reinforcing ribs 161, and two adjacent regular polygon reinforcing ribs 161 share one side. It can be understood that the regular polygon reinforcing ribs 161 can be triangles, squares, regular pentagons, regular hexagons, etc.

[0036] Please refer to Figure 1 , Figure 2 and Figure 4 , the top cover 200 is provided with an avoidance groove 230 adapted to the buckle plate 120. By setting the avoidance groove 230, the outer surface after the docking of the buckle part and the bottom shell 100 is flat, and the appearance is beautiful.

[0037] Please refer to Figures 1 - 3 , the buckle plate 120 is trapezoidal. The connection strength of the bottom of the card plate is improved.

[0038] Please refer to Figure 3 and Figure 4 , the first buckle part 121 is a convex block, the second buckle part 220 is a card slot, and the convex block has a transition surface 221 that gradually thins downward. Particularly, the height of the convex block is lower than the depth of the card slot or is flush with the card slot. Or, the first buckle part 121 can also be a card slot, and the second buckle part 220 is a convex block. The transition surface 221 can be an inclined surface or a curved surface, which is specifically set according to needs.

[0039] Please refer to Figures 1 - 3, several lugs 170 are provided on two side surfaces of the bottom shell 100, and metal bushings are fixed inside the lugs 170. At least two of the metal bushings form a waist-shaped hole 172, a small round hole 174, or a large round hole 173. That is, the metal bushings form connection holes of different shapes, and the connection holes of different shapes can be used as adjustment holes, with strong adaptability and more convenience during installation. The metal bushings can avoid torque attenuation caused by long-term locking of bolts on plastics. If the metal bushings are not inlaid, and at the same time the power supply unit is fixed to the whole vehicle by bolts through the fixing mounting feet of the lugs 170, then with the long-term vibration and impact of the whole vehicle, due to the plastic deformation of the plastic, the screws squeeze the plastic lugs 170 for a long time, resulting in defects such as deformation of the screw parts of the lugs 170, and finally leading to attenuation or even failure of the fixing bolt torque. Particularly, four lugs 170 are provided, with 2 on each of the left and right sides of the bottom shell 100. The metal bushings inside the four lugs respectively form 1 small round hole 174, 1 waist-shaped hole 172, and 2 large round holes 173, mainly considering the four-hole position tolerances during the installation of the whole vehicle. The installation hole positions of the bottom plate sheet metal on the whole vehicle generally have large tolerances; through 1 small round hole 174 + 1 waist-shaped hole 172 + 2 large round holes 173, first install the small round hole 174 during installation, second install the waist-shaped hole 172, and finally install the remaining two large round holes 173; in this way, it can effectively avoid the problem that the hole positions are misaligned and cannot be installed due to the large tolerances of the installation hole positions of the bottom plate sheet metal of the whole vehicle.

[0040] Please refer to Figures 1 - 3 , the two ends of the lug 170 extend with inclined ribs 171 in the front-back direction. The strength of the lug 170 is strengthened by the inclined ribs 171.

[0041] Please refer to Figure 3 , the inner extension part 130 has several notches 131. When the top cover 200 and the bottom shell 100 are sealed and connected by sealant, the setting of the notches 131 can prevent the glue from overflowing to the outside, and the deliberately opened notches 131 allow the excess sealant to overflow inward.

[0042] Preferably, the bottom shell 100 is generally in the shape of a cuboid with an upward opening, and a buckle plate 120 is provided on each side of the open end of the bottom shell 100.

[0043] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, then the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, then the directional indications will also change accordingly.

[0044] In addition, if descriptions such as "first" and "second" are involved in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0045] In summary, a low-voltage automotive starting power supply housing provided by the present utility model has a groove formed by an outer extension part and an inner extension part of the bottom shell. The top cover is nested with the groove and adhesively connected through a sealant. The groove can facilitate the storage of the sealant, and the first buckle part on the clamping plate is buckled with the second buckle part on the top cover, enabling the bottom shell and the top cover to form a fast and stable connection, which is convenient to operate and has a low cost. Moreover, the strength of the housing and the convenience of installation are considered simultaneously.
