[0002] Vehicle batteries are usually placed on the floor of the front cabin or luggage compartment and connected to the vehicle body through a mounting bracket. With the continuous improvement of vehicle safety indicators, the existing battery mounting bracket structure can no longer meet the requirements. The main reason is that the battery is fixed to the mounting bracket by a hook rod connected to a pressure plate. When the vehicle is hit head-on, the battery may be directly impacted. At the same time, due to the large forward inertia of the battery in a head-on collision, the part where the mounting bracket is connected to the hook rod is instantly subjected to high-strength pulling force, which can easily cause the mounting bracket to break and fail, affecting the safety performance of the vehicle.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it may be directly on the other element or indirectly on the other element. It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0023] The terms "first" and "second" used in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0024] Please also read Figures 1 to 3 The battery mounting bracket provided by the utility model is now described. The battery mounting bracket includes a support plate 10 and a limiting frame 20; the support plate 10 is fixedly connected to the vehicle body and supports the battery along the front and rear direction of the vehicle body, and the edge areas of the support plate 10 on both sides along the width direction of the vehicle body are folded upward to form side guards 11, and the side guards 11 are connected to the battery pressure plate hook; the front end area of ​​the support plate 10 is folded upward to form a first flange 12; the limiting frame 20 blocks the front end of the battery and is connected to the first flange 12, and the two ends of the limiting frame 20 are respectively bent backward and connected to the two side guards 11.

[0025] It should be noted that in the present embodiment, both the support plate 10 and the limit frame 20 are die-cast or stamped as separate components, thereby simplifying the molding process and reducing the cost of mold design and development. At the same time, different materials and thicknesses of substrates can be selected for processing according to different parts, thereby controlling material costs while ensuring structural strength. For example, the support plate 10 can be stamped and made of 1.2 mm thick steel plate of HC340 / 590DP or HC340 / 590DH, and the limit frame 20 can be stamped and made of 1.5 mm thick steel plate of HC340 / 590DP or HC340 / 590DH, thereby meeting the installation and performance requirements of 70Ah / 72Ah large-capacity batteries. Of course, the material and thickness of the support plate 10 and the limit frame 20 can be adaptively adjusted according to the installation and performance requirements of the battery matching the vehicle model.

[0026] In this embodiment, after the processing of the support plate 10 and the limit frame 20 is completed, they can be connected by screwing, riveting or welding. Considering the connection reliability and process convenience, it is preferred to adopt the method of welding and fixing the two bent ends of the limit frame 20 to the two side flanges 11 on both sides of the support plate 10 respectively; specifically, the limit frame 20 can be a U-shaped component. During assembly, the limit frame 20 is straddled on both sides of the support plate 10, so that the bent parts at both ends thereof respectively form at least partial overlap with the two side flanges 11, and at least two welding points are arranged in the overlapping area. In addition, in order to ensure the convenience of assembly, the spacing between the bent ends of the limit frame 20 in the width direction of the vehicle body is greater than the outer side spacing of the two side flanges 11, so as to ensure that there is a movable gap of about 0.3mm between the limit frame 20 and the side flanges 11, thereby reducing the difficulty of assembly.

[0027] In this embodiment, the connection between the support plate 10 and the vehicle body can be screwed, riveted or welded. Considering the convenience of the later assembly process, it is preferred to use the method of welding the support plate 10 to the vehicle body, thereby saving the man-hours of assembling the support plate 10 on the vehicle body in the later stage, which is conducive to improving the assembly efficiency. Similarly, the connection between the limit frame 20 and the side guard 11 and the first flange 12 can also be screwed, riveted or welded. In this embodiment, the welding fixation method is also preferred.

[0028] It should be noted that sufficient assembly clearance should be reserved between the battery mounting bracket and the battery provided in this embodiment. Specifically, the spacing between the two side guard edges 11 should be greater than 6 mm of the width of the battery. Since the rear end of the battery is not constrained or limited, the front end of the battery is required to abut against the limit frame 20, thereby avoiding the battery from colliding with the limit frame 20 under the forward inertia force. The gap between the battery mounting bracket and its surrounding parts should be more than 5 mm. Considering the risk of pressing on the surrounding wiring harness when installing the battery, a safety gap of more than 10 mm should be ensured between the installation position of the battery and the surrounding wiring harness.

[0029] Compared with the prior art, the battery mounting bracket provided in the present embodiment adopts an integral structural mode formed by connecting the support plate 10 and the limiting frame 20, which can reduce the difficulty and cost of the processing technology, and can adaptively select the material characteristics of the support plate 10 and the limiting frame 20, and has high processing flexibility; the battery is placed between the two side guards 11 of the support plate 10 and the side guards 11 provide a connection point for the pressure plate hook, and the side guards 11 can be used to constrain the battery in the width direction of the vehicle body, thereby preventing the battery from falling off the support plate 10 when the vehicle collides sideways; the limiting frame 20 can block the front end of the battery, which can not only prevent the battery from falling off when the vehicle collides head-on The front end of the battery can be prevented from being damaged by collision, and the battery can be prevented from slipping off the front end of the support plate 10 under the forward inertia force. At the same time, the pulling force on the side guard edges 11 on both sides of the support plate 10 during a head-on collision can be reduced by the barrier effect on the battery, thereby avoiding the risk of breakage due to concentrated force on the bent part of the edge of the support plate 10, thereby improving the installation reliability of the battery and the collision safety performance of the vehicle; in addition, the first flange 12 formed by folding upward a local area of ​​the front end of the support plate 10 can not only form a barrier limit for the bottom of the front end of the battery, but also can improve the overall structural strength through the connection between the first flange 12 and the limit frame 20, thereby further improving the installation reliability of the battery.

[0030] In some embodiments, see Figure 1 and Figure 3 The front end portion of the support plate 10 is folded upward to form a second flange 13, the second flange 13 is blocked in front of the battery, and the second flange 13 and the first flange 12 are spaced apart along the width direction of the vehicle body, and the top end of the second flange 13 is folded forward to form an accessory mounting surface 131.

[0031] Since the battery needs to be connected to the wiring harness, wire clip or other accessories after installation, a second flange 13 is set at the front end of the tray 10 in this embodiment, and the top end of the second flange 13 is folded forward to form an accessory mounting surface 131. Not only can the accessory mounting surface 131 be used to provide an accessory mounting position for the battery and ensure that there is a sufficient safety distance between the accessory and the battery body, but the second flange 13 and the first flange 12 can also be used to provide a forward barrier limit for the bottom of the front end of the battery, thereby improving the installation reliability of the battery. The flange structure is also beneficial to improving the front end structural strength of the tray 10 and reducing the risk of deformation and breakage of the tray 10 due to stress.

[0032] Taking into account the specific shape of the front end of the battery, if the front end of the battery is a common flat end face structure, then the second flange 13 and the first flange 12 should both remain flush along the width direction of the vehicle body, thereby ensuring that both can simultaneously form an abutment limit to the front end of the battery; if the front end of the battery is a non-flat end face structure, then the second flange 13 and the first flange 12 should both be adaptively staggered along the width direction of the vehicle body, thereby ensuring that both can stably abut the front end of the battery, thereby ensuring the reliability of the front end limit of the battery.

[0033] In addition, in this embodiment, the portion of the limit frame 20 that blocks the front end of the battery is higher than the second flange 13, thereby forming a structure in which the second flange 13 abuts and limits the bottom of the front end of the battery, and the limit frame 20 abuts and limits the middle and upper area of ​​the front end of the battery, so that the front end of the battery can obtain stable limitation as a whole, thereby improving the installation reliability of the battery.

[0034] For some possible implementations, see Figure 1 and Figure 2 A reinforcing plate 30 is provided at the folded parts on both sides of the support plate 10. The middle part of the reinforcing plate 30 is bent and a first plate body 31 and a second plate body 32 are formed on both sides of the bent part respectively; wherein the first plate body 31 is fitted and fixed to the upper surface of the support plate 10, and the second plate body 32 is fitted and fixed to the side guard edge 11.

[0035] Since the two side edges of the support plate 10 are folded to form the side guard 11, the bending position is a relatively weak part and is also a part where the force is concentrated. Therefore, the risk of fracture is relatively high. At the same time, the side guard 11 is also prone to vibrate in the width direction of the vehicle body, thereby increasing the risk of fracture at the folded part of the support plate 10. Therefore, by providing reinforcing plates 30 at the bent parts on both sides of the support plate 10, a double-layer structure can be formed in this part, which can not only improve the structural strength of the joint parts of the two sides of the support plate 10 and the side guard 11, and reduce the risk of fracture at the folded part of the support plate 10, but also improve the stiffness of the side guard 11 along the width direction of the vehicle body, thereby avoiding the side guard 11 from vibrating in the width direction of the vehicle body, and further reducing the risk of fracture at the folded part of the support plate 10.

[0036] Specifically, the reinforcing plate 30 can be stamped from a 1.6 mm thick steel plate of HC340 / 590DP or HC340 / 590DH. In addition, a reinforcing rib 33 is provided at the bending portion of the reinforcing plate 30, one end of the reinforcing rib 33 extends to the middle of the first plate body 31, and the other end extends to the middle of the second plate body 32. The reinforcing rib 33 can be provided to improve the structural strength of the angle between the first plate body 31 and the second plate body 32, thereby improving the bonding strength between the side guard 11 and the folded area of ​​the edge of the support plate 10, preventing the side guard 11 from vibrating in the width direction of the vehicle body and affecting the life of the support plate 10, thereby ensuring the installation reliability of the battery.

[0037] As a modified embodiment of the above-mentioned support plate 10, please refer to Figure 1 and Figure 3 The support plate 10 has a plurality of recessed areas 14 spaced apart along the front-rear direction of the vehicle body, and the lower surface of each recessed area 14 forms a welding surface 141, which is attached to the vehicle body and welded and fixed to the vehicle body.

[0038] The recessed areas 14 arranged at intervals can form a wavy plate surface shape for the support plate 10, thereby improving the structural strength of the support plate 10. At the same time, the bottom surface of the recessed area 14 as the lowest surface of the support plate 10 can be attached to the vehicle body as a welding surface 141 and welded and fixed, and the area between adjacent recessed areas 14 is a relatively arched structure, so it can serve as a supporting area that directly contacts the bottom wall of the battery.

[0039] The method of welding and fixing the welding surface 141 to the vehicle body can directly weld the battery mounting bracket to the vehicle body when the vehicle body is assembled. Compared with the current method of screwing and fixing, it can not only save the time of reassembling the battery mounting bracket to the vehicle body at a later time, thereby simplifying the assembly process, but also help to improve the assembly position accuracy between the battery mounting bracket and the vehicle body.

[0040] In this embodiment, the formation of the recessed area 14 will inevitably form a vertical wall along the height direction of the vehicle body on the support plate 10. Considering the smooth demolding of the stamping process, the vertical walls on the front and rear sides of each recessed area 14 are designed with a demolding angle of 1° to 3°.

[0041] It should be noted that in order to improve the structural strength of the support plate 10, Figure 1 and Figure 3 As shown, a plurality of first reinforcing structures 15 that are convex upward and / or concave downward are distributed on the support plate 10. The convex or concave first reinforcing structures 15 can improve the board surface structural strength and bearing capacity of the support plate 10, thereby being able to use lighter and thinner materials to prepare the support plate 10 while meeting the strength requirements of the support plate 10, thereby facilitating weight reduction.

[0042] Specifically, considering that the recessed areas 14 extending along the width direction of the vehicle body and distributed at intervals in the front and rear on the support plate 10 are beneficial to improving the strength of the support plate 10 in the width direction of the vehicle body, the first reinforcing structure 15 can be set to extend along the front and rear direction of the vehicle body, thereby improving the structural strength of the support plate 10 in the front and rear direction of the vehicle body, and the two cooperate to improve the overall structural strength of the support plate 10.

[0043] Specifically, the first reinforcing structure 15 may be a concave long groove or a round cavity or an elongated round cavity, or a convex long rib or round rib, and the concave depth or convex height may be about 5 mm.

[0044] Optionally, in this embodiment, a first weight-reducing hole 151 or a drainage hole 152 is provided on the first reinforcing structure 15 that is recessed downward, and the boundary of the first weight-reducing hole 151 has a first reinforcing flange 1511. The shape of the first weight-reducing hole 151 should match the shape of the first reinforcing structure 15. On the basis of the first reinforcing structure 15 forming a structural reinforcement for the support plate 10, the first weight-reducing hole 151 can be provided to reduce the weight of the support plate 10, thereby promoting the achievement of lightweight indicators. At the same time, the first reinforcing flange 1511 is provided on the boundary of the first weight-reducing hole 151, thereby avoiding the boundary position of the first weight-reducing hole 151 from being torn by force, thereby increasing the effective service life of the support plate 10.

[0045] It should be explained that for the first reinforcing structure 15 with a smaller shape and a downward depression, a drainage hole 152 is opened (since the weight reduction effect of the small hole is not obvious, it is called a drainage hole 152) to avoid water accumulation in the depressed part, which of course also has a certain weight reduction effect; and for the first reinforcing structure 15 with a larger shape, a first weight reduction hole 151 is directly opened. Here, the first weight reduction hole 151 has a weight reduction effect and can also drain the depressed area 14.

[0046] For some possible implementations, see Figure 3 The limiting frame 20 blocks the front end of the battery to form a limiting portion 21, and the bending portions at both ends of the limiting frame 20 respectively form connecting portions 22; wherein the connecting portion 22 is overlapped and fixed to the side guard 11; the limiting portion 21 has a second reinforcing structure 211 extending along the width direction of the vehicle body, and the second reinforcing structure 211 has a plurality of second weight-reducing holes 212 spaced apart along its extending direction.

[0047] The second reinforcing structure 211 can be a rib protruding from the surface of the limiting portion 21 or a recessed groove, thereby improving the bearing capacity of the limiting portion 21 along the front-rear direction of the vehicle body, preventing the limiting portion 21 from bending forward due to the battery pressing against the limiting portion 21, thereby improving the isolation stability of the limiting portion 21 to the battery. In addition, on the basis of ensuring the strength of the limiting portion 21, the second weight-reducing hole 212 is opened on the second reinforcing structure 211 to reduce the weight of the limiting frame 20, thereby promoting the achievement of lightweight indicators.

[0048] The above-mentioned connecting portion 22 can be a structure whose width (dimension in the height direction) gradually increases from the back to the front. On the one hand, this can increase the front end dimension of the connecting portion 22, thereby improving the structural strength of the connection between the connecting portion 22 and the limiting portion 21. On the other hand, it can avoid the rear end of the connecting portion 22 overlapping the side guard 11 due to being too large and interfering with the installation of the pressure plate hook.

[0049] It is important to understand that see Figure 1 and Figure 3 In this embodiment, a hook hole 111 for connecting the pressure plate hook is provided on the side guard 11, and the boundary of the hook hole 111 has a second reinforcing flange 112. The hook hole 111 can be conveniently connected with the pressure plate hook by providing the hook hole 111, thereby improving the convenience of battery assembly and fixation. At the same time, in order to prevent the hook hole 111 from being torn due to force, the boundary of the hook hole 111 is provided with a second reinforcing flange 112. The boundary strength of the hook hole 111 is improved by the second reinforcing flange 112, thereby reducing the risk of the hook hole 111 being torn due to force, thereby improving the reliability of battery installation and fixation.

[0050] Based on the same inventive concept, Figures 1 to 3 It is understood that an embodiment of the present application also provides a vehicle, including the above-mentioned battery mounting bracket.

[0051] Compared with the prior art, the vehicle provided by this embodiment adopts the above-mentioned battery mounting bracket, which can not only prevent the front end of the battery from being damaged when the vehicle collides head-on, but also prevent the battery from slipping off the front end of the support plate 10 under the forward inertia force. At the same time, the limiting frame 20 can also reduce the pulling force on the side guard edges 11 on both sides of the support plate 10 during a head-on collision through the blocking effect of the battery, thereby avoiding the risk of fracture caused by concentrated force on the bent edge of the support plate 10, improving the overall structural strength and the installation reliability of the battery, and thus improving the collision safety performance of the vehicle.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
