[0002] With the rapid development of the new energy vehicle industry, the demand for electricity in vehicles is also increasing, and consequently, the capacity and size of vehicle batteries are also increasing. In traditional vehicles, batteries are usually located in the engine compartment. However, with the increase in battery capacity and size, existing vehicles often choose to install batteries on the rear floor to ensure connection stability.

[0003] However, regarding the installation and fixation of batteries on the rear floor, most technologies use plastic trays fixed to the rear floor for installation and support. But this area is prone to deformation in high-speed rear-end collisions, and these technologies lack corresponding protective measures. Especially in rear-end collisions at 80 km / h, the battery is easily squeezed by the deformed rear panel, leading to cell deformation and even the risk of battery fire. Utility Model Content

[0004] In view of the above problems, this utility model provides a mounting and protective bracket for vehicle batteries, which can effectively improve the protection of batteries and reduce the probability of batteries being squeezed and deformed in rear-end collisions.

[0034] like Figures 1 to 3As shown, this embodiment provides a mounting and protective bracket for a vehicle battery, including a tray 1 and a baffle 2. The tray 1 is used to support the battery and is suitable for fixed connection with the vehicle floor. The baffle 2 is mounted on the tray 1 and includes a main body 21, a support 22, and a flange 23. The main body 21 is arranged with its normal direction facing the front-rear direction x. The two ends of the main body 21 distributed in the left-right direction y are bent forward along the front-rear direction x to form the support 22. The bottom of the main body 21 and the support 22 are bent horizontally to form the flange 23, and are connected to the tray 1 through the flange 23. The connection method includes, but is not limited to, bolt connection. The main body 21 and the support 22 at both ends form an installation space for placing the battery. The tray 1 is provided with a limiting component 11 for positioning and fixing the battery in the installation space. In this way, the baffle 2 can be installed around the rear end of the battery, and the main body 21 of the baffle 2 can effectively protect the battery in the event of a rear-end collision, preventing the deformed body sheet metal from directly squeezing the battery. At the same time, the support part 22 can provide effective support for the main body 21, and the flange part 23 can provide a stable connection between the main body 21 and the support part 22, so that the baffle 2 has high structural strength and good collision energy absorption effect, thereby effectively reducing the probability of the battery being squeezed and deformed in the event of a rear-end collision.

[0035] It is understood that the aforementioned limiting component 11 can be used to position and fix the battery by means of binding, snap-fitting, bolt connection, etc. The specific fixing method and corresponding implementation structure are existing technologies, and can be selected and set according to actual needs. No restrictions are imposed here and will not be elaborated further.

[0036] The aforementioned flange 23 can be bent outward in the horizontal direction (with the side where the installation space is located as the inside) to form a shape. That is, the bottom of the main body 21 bends backward in the front-back direction x, the bottom of the left support 22 bends to the left in the left-right direction y, and the bottom of the right support 22 bends to the right in the left-right direction y. The three flange sections 23 are connected to the left and right ends of the main body 21 as a whole, forming a U-shape. Bolt connection holes are opened on the flange 23 and the tray 1 respectively. The two are fixed together by bolt assembly to realize the fixed connection between the flange 23 and the tray 1. This avoids the flange 23 and its connection structure from interfering with the installation and fixation of the battery in the installation space, improves the space utilization of the installation protection bracket, and makes its structure compact.

[0037] The aforementioned baffle 2 can be integrally formed from aluminum alloy material through die casting, making the main body 21, support 22, and flange 23 a single unit. This reduces the number of connecting parts, improves the integration and structural strength of the baffle 2, and meets the lightweight requirements of the baffle 2. Similarly, the aforementioned tray 1 can also be an integrally formed cast aluminum part to ensure structural strength and meet lightweight requirements.

[0038] In some embodiments, such as Figures 1 to 3 As shown, the baffle 2 also includes a reinforcing part 24, which is at least partially located on the upper part of the main body 21 (the area near the upper end of the main body 21) and protrudes rearward from the main body 21 in the longitudinal direction x. In this way, in the event of a rear-end collision, the deformed body sheet metal (such as the rear panel) will first contact the reinforcing part 24, which will absorb some of the collision energy by absorbing the initial impact. Then, through the collapse of the reinforcing part 24, the collision energy absorption effect of the mounting protective bracket is improved, and the intrusion of the mounting protective bracket into the rear-end collision is reduced, thereby better protecting the battery.

[0039] Understandably, the reinforcing part 24 can be integrally formed with the main body 21, the supporting part 22, and the flanged part 23 using aluminum alloy material through die casting. The structure of the reinforcing part 24 is similar to that of an energy-absorbing box. There is a cavity between its interior or its collision contact surface and the main body 21. Its structure can withstand a certain impact load and collapses after the load exceeds the limit to absorb the energy generated by the collision. Furthermore, after the battery is fixed on the tray 1, the main body 21 and the battery can be spaced apart, thereby providing an energy-absorbing space between the main body 21 and the battery and reducing the damage to the battery caused by the collision deformation of the main body 21.

[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, the reinforcing part 24 is connected to the supporting part 22 on the side near the main body part 21, and corresponds to the supporting part 22 in the front-rear direction x. In this way, the supporting part 22 can provide sufficient support for the reinforcing part 24 in the front-rear direction x, ensuring that the reinforcing part 24 can deform fully, and can effectively transfer the collision energy to the tray 1 through the supporting part 22, thereby achieving the purpose of effectively absorbing the collision energy.

[0041] In some embodiments, such as Figures 1 to 3 As shown, the reinforcing part 24 is provided on at least one side of the main body 21 along the left-right direction y, and is offset from the main body 21 in the front-back direction x. This avoids direct impact on the main body 21, thereby reducing the impact force. Simultaneously, since the battery is installed within the installation space formed by the main body 21 and the support part 22, and the positive terminal of the battery is usually located on either side of the left-right direction y, and is connected to various connectors such as junction boxes, the reinforcing part 24 can be correspondingly positioned on the side where the positive terminal of the battery is located, preventing bolts and other parts protruding from the rear panel from damaging the connectors at the positive terminal of the battery.

[0042] In some embodiments, such as Figures 2 to 5As shown, the reinforcing part 24 includes a support plate 241, two side plates 242, and at least one rib 243. The support plate 241 is arranged in the normal direction of its surface toward the front-rear direction x, and is located behind the main body 21 in the front-rear direction x. In this way, the support plate 241 serves as a collision contact surface, and can be impacted before the main body 21 in a rear-end collision, thus absorbing some of the collision energy in advance. The two side plates 242 are both arranged in the normal direction of their surfaces toward the left-right direction y, and are respectively connected to the left and right sides of the support plate 241 in the left-right direction y. At the same time, one of the side plates 242 is connected to the main body 21 and is aligned with the support plate 241 in the front-rear direction x. Corresponding to the support part 22, the force transmission path can be optimized to the support part 22, and the support strength of the support plate 241 can be strengthened; the other side plate 242 extends downward along the height direction z to connect with the flange part 23, which can transmit the impact force downward to the pallet 1 and effectively bear the impact force; the rib plate 243 is arranged in the normal direction of the plate surface towards the left and right direction y, and is located between the two side plates 242 in the left and right direction y, and its two ends distributed in the front and rear direction x are respectively supported by the support plate 241 and the flange part 23, which can effectively improve the support strength of the support plate 241 and ensure that the impact force can be effectively transmitted to the pallet 1.

[0043] Furthermore, such as Figures 2 to 5 As shown, the lower part of the support plate 241 bends forward along the front-rear direction x and extends downward along the height direction z to connect with the flange 23. In this way, the support plate 241 can have lateral support distributed along the front-rear direction x at the bend, thereby improving the structural strength of the reinforcing part 24. At the same time, the support plate 241 forms a hollow space below the bend, which can meet the requirements of lightweighting and ensure effective demolding of the part during the die casting process, thus ensuring its structural strength and rigidity performance.

[0044] It is understandable that, based on the structural arrangement of the support plate 241 described above, the ribs 243 can be correspondingly distributed on the upper and lower sides of the lower part of the support plate 241, or correspondingly distributed on the front and rear sides of the lower part of the support plate 241, or correspondingly distributed on both the upper and lower sides and the front and rear sides of the lower part of the support plate 241. Specifically, as... Figures 2 to 5As shown, the ribs 243 in this embodiment are provided in five sets, including three sets of ribs 243 disposed on the front side of the support plate 241 and two sets of ribs 243 disposed on the rear side of the support plate 241. The support plate 241, after being bent, can be divided into a vertically arranged upper panel 2411, a horizontally arranged middle panel 2412, and a vertically arranged lower panel 2413. One set of the three sets of ribs 243 disposed on the front side of the support plate 241 is disposed on the upper part of the support plate 241 and is triangularly supported between the upper panel 2411 and the middle panel 2412 of the support plate 241. The other two sets are disposed at intervals on the support plate 241. The lower part of plate 241 is triangularly supported between the lower panel 2413 and the flange 23 of support plate 241. A set of ribs 243 on the upper part of support plate 241 corresponds to one set of ribs 243 on the lower part of support plate 241 in the front-rear x-direction. Two sets of ribs 243 on the rear side of support plate 241 are spaced apart on the lower part of support plate 241 and located in the hollow space below support plate 241. Their upper ends are connected to the middle panel 2412 of support plate 241, their lower ends are connected to the flange 23, and their front ends are connected to the lower panel 2413 of support plate 241. This arrangement ensures a continuous force transmission path for the ribs 243, providing effective support for support plate 241.

[0045] It is also understood that the embodiments described above with reference to the accompanying drawings are exemplary and intended to explain the arrangement of the reinforcing part 24, and should not be construed as limiting the present application. In other embodiments, the number, shape and size of the support plate 241, side plate 242 and rib plate 243 can be selected and arranged according to specific needs (such as the shape and size of the baffle 2), which will not be elaborated here.

[0046] In some embodiments, such as Figure 3 As shown, the main body 21 is arranged in a stepped manner along the left-right direction y. On the one hand, it can improve the deformation resistance of the main body 21 in the front-back direction x. On the other hand, it can leave an energy-absorbing space between the main body 21 and the battery, reducing the damage to the battery caused by the collision deformation of the main body 21.

[0047] Furthermore, such as Figure 3 As shown, after the main body 21 is arranged in a stepped shape, the position of the side of it closer to the reinforcing part 24 in the front-rear direction x is further back than the position of the side of it farther away from the reinforcing part 24 in the front-rear direction x. In this way, the connection node between the main body 21 and the reinforcing part 24 can be arranged relatively rearward in the front-rear direction x, so that the part of the reinforcing part 24 that protrudes backward from the main body 21 can be fully collapsed.

[0048] In some embodiments, such as Figure 2 and Figure 3As shown, the baffle 2 is also provided with several reinforcing ribs 25. One end of the reinforcing rib 25 extends along the height direction z and is disposed in the main body 21, while the other end of the reinforcing rib 25 extends along the front-rear direction x and is disposed in the flange 23. Specifically, the reinforcing rib 25 is triangular in shape, with its front right-angled side connected to the rear side of the main body 21 along the height direction z, and its lower right-angled side connected to the flange 23 along the front-rear direction x. Its hypotenuse serves as a diagonal brace supporting the main body 21 and the flange 23. By providing the reinforcing ribs 25, the structural strength of the baffle 2 can be improved, and the deformation resistance of the main body 21 can be enhanced.

[0049] Understandably, the extension lengths of the right-angled sides of the multiple reinforcing ribs 25 can be set at different heights according to requirements, so as to maximize the weight reduction while ensuring the strength of the baffle 2.

[0050] Furthermore, in high-speed rear-end collisions, besides the rear panel deforming and shifting forward, the rear floor also tends to fold downwards, potentially causing tray 1 to be pulled downwards and bend, causing the battery to detach from tray 1. In some embodiments, such as... Figure 1 and Figure 6 As shown, the tray 1 includes a base plate 12 and several legs 13. The base plate 12 is used to place the battery, and the aforementioned limiting component 11 for positioning and fixing the battery is set on the upper surface of the base plate 12. Several legs 13 are arranged around the circumference of the base plate 12 on the lower surface of the base plate 12. The legs 13 can support the tray 1, so that the tray 1 is spaced apart from the vehicle floor below. On the other hand, the legs 13 can be fixedly connected to the vehicle floor by bolts, so that the tray 1 is fixed on the vehicle floor. A side plate 14 is also connected between two adjacent legs 13. The upper end of the side plate 14 is connected to the lower surface of the base plate 12, which can improve the support stability of the legs 13 and the structural strength of the base plate 12. Among them, the lower end of the side plate 14 distributed along the front-rear direction x is curved upward. On the one hand, it can provide sufficient support for the tray 1 in the height direction z and the front-rear direction x, preventing the tray 1 from bending in the middle. On the other hand, it can effectively ensure the assembly gap between the battery and the bottom wiring harness.

[0051] In some embodiments, such as Figure 7As shown, the lower surface of the base plate 12 is also provided with several reinforcing ribs 15. The reinforcing ribs 15 include transverse reinforcing ribs 151, longitudinal reinforcing ribs 152, and diagonal reinforcing ribs 153. The transverse reinforcing ribs 151 extend along the left-right direction (y), and the longitudinal reinforcing ribs 152 extend along the front-back direction (x), with the transverse and longitudinal reinforcing ribs 151 and 152 perpendicularly intersecting each other. The diagonal reinforcing ribs 153 are inclined from back to front along the front-back direction (x) and from inside to outside along the left-right direction (y) (based on the overall outline of the base plate 12), and connect to the junction of the transverse and longitudinal reinforcing ribs 151 and 152. The arrangement of these reinforcing ribs 15 effectively improves the deformation resistance of the base plate 12, preventing shear failure during collisions that could affect the battery's trajectory.
