Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a mounting bracket and a vehicle. Background Technology

[0002] In recent years, new energy vehicles have experienced rapid development. In the field of electric vehicles, batteries, as the power source, play an irreplaceable and crucial role. To integrate batteries into vehicles, corresponding mounting structures are typically installed on the vehicle based on the battery's structure and mounting point characteristics to meet the battery's installation requirements. Alternatively, corresponding mounting structures are fabricated on the battery based on the vehicle's structure and mounting point characteristics to meet the battery's installation requirements. This either increases the design and manufacturing complexity of the vehicle or the battery. Summary of the Invention

[0003] This application provides a mounting bracket and a vehicle, which reduces the design and manufacturing difficulties of the battery and the vehicle body while ensuring that the battery can be mounted on the vehicle.

[0004] In a first aspect, embodiments of this application provide a mounting bracket for mounting a battery to a vehicle body. The mounting bracket has a mounting portion for connecting the mounting bracket to the vehicle body.

[0005] In the above technical solution, the battery is installed on the vehicle body by setting a mounting bracket between the vehicle body and the battery. This allows for flexible design of the shape and structure of the mounting bracket based on the characteristics of the vehicle body and the battery, so as to meet the requirements that the battery can be mounted on the vehicle, thereby reducing the design and processing difficulty of the battery and the vehicle body.

[0006] In some embodiments, the mounting bracket includes two side brackets and a central bracket connecting the two side brackets, the two side brackets being adapted to be located on both sides of the vertical space where the longitudinal beams of the vehicle body are located.

[0007] In the above technical solution, since the mounting frame includes two side frame parts and a central frame part, the mounting frame has good structural strength and strong load-bearing capacity for the battery, which can improve the stability of the battery mounted on the vehicle. Moreover, since the mounting frame includes side frame parts located on both sides of the vertical space, the mounting frame can make full use of the space under the vehicle, which is beneficial for supporting batteries with larger capacities.

[0008] In some embodiments, at least a portion of the side frame is adapted to be above the lower end of the underbody longitudinal beam to be located to the side of the underbody longitudinal beam.

[0009] In the above technical solution, the side frame is not entirely lower than the longitudinal beam of the vehicle floor, which makes it easier to utilize the horizontal space on both sides of the longitudinal beam of the vehicle floor to set at least a part of the side frame, thereby improving space utilization.

[0010] In some embodiments, the side frame is adapted to be located between the vehicle body and the battery.

[0011] In the above technical solution, since at least part of the side frame is located between the vehicle body and the battery, it can be well hidden, thus protecting the battery and the vehicle body and reducing the probability of the part being eroded by mud and water or damaged by impacts from external objects, thereby improving the stability of the battery mounted on the vehicle.

[0012] In some embodiments, the side frame portion is adapted to extend along the length of the vehicle underbody longitudinal beam and is sandwiched between the battery and the side wall of the vehicle underbody longitudinal beam.

[0013] In the above technical solution, the side frame can be protected by the battery and the longitudinal beams of the vehicle floor, reducing the probability of the side frame being corroded by mud and water or damaged by impacts from external objects, and improving the stability of the battery mounted on the vehicle. Moreover, the side frame has a smaller dimension in the width direction of the longitudinal beams of the vehicle floor, reducing the risk of breakage of the side frame and the connection between the side frame and the center frame, thereby improving the structural reliability of the mounting bracket.

[0014] In some embodiments, the mounting portion includes a first mounting portion disposed on the side frame portion.

[0015] In the above technical solution, since the side frame is located on both sides of the vertical space where the longitudinal beam of the vehicle bottom is located, the first mounting part is set on the side frame. This means that the first mounting part can also be located on the outside of the longitudinal beam of the vehicle bottom. There is enough space here, which facilitates the connection between the first mounting part and the vehicle body, and also facilitates the flexible design of the first mounting part.

[0016] In some embodiments, the side frame includes a first extension that extends along the length of the vehicle underbody longitudinal beam and is sandwiched between the battery and the side wall of the vehicle underbody longitudinal beam, and a first mounting portion is disposed on the first extension and adapted to be connected to the side wall of the vehicle underbody longitudinal beam.

[0017] In the above technical solution, since the first mounting part is located on the first extension part sandwiched between the battery and the vehicle bottom longitudinal beam, the first mounting part can also be easily hidden and protected by the battery and the vehicle bottom longitudinal beam, thereby improving the connection reliability between the first mounting part and the vehicle bottom longitudinal beam.

[0018] In some embodiments, the first mounting portion is adapted to be connected to the sidewall of the longitudinal beam of the vehicle floor by a first fastener extending laterally.

[0019] The above technical solution simplifies the connection between the first mounting part and the vehicle body and improves the reliability of the connection. Furthermore, it simplifies the structure and processing of the side frame and the longitudinal beams of the vehicle floor, and improves the tightness of the fit between the side frame and the longitudinal beams of the vehicle floor.

[0020] In some embodiments, the first extension is provided with a plurality of first mounting portions, which are adapted to be spaced apart along the length direction of the longitudinal beam of the vehicle floor.

[0021] In the above technical solution, since multiple first mounting parts are spaced apart along the length of the vehicle bottom longitudinal beam, the space of the first extension can be fully utilized, and more first mounting parts can be set, which improves the connection reliability between the mounting bracket and the vehicle body. Furthermore, multiple first mounting parts are less likely to interfere with the vehicle bottom longitudinal beam when connected, which is beneficial to the connection operation.

[0022] In some embodiments, the mounting bracket includes a frame and mounting ears, the mounting ears being fitted to the frame and defining a first mounting portion.

[0023] In the above technical solution, since the first mounting part is defined by the mounting lugs assembled to the frame, the design and processing difficulty of the frame can be reduced, and the design and processing requirements of the first mounting part can be met.

[0024] In some embodiments, the mounting ears are detachably connected to the frame.

[0025] The above technical solution can meet the needs of disassembling and replacing the mounting ear, thus improving adaptability.

[0026] In some embodiments, the mounting bracket further includes a gasket that is detachably disposed between the mounting ear and the bracket body.

[0027] In the above technical solution, it is possible to choose whether to install a shim or what size shim to install, depending on the actual situation of the vehicle model and the actual situation of the mounting points on the vehicle body, so as to adapt to the installation needs of different vehicle models.

[0028] In some embodiments, the mounting portion includes a first connecting portion disposed on the side frame portion, the first connecting portion being used to connect the mounting bracket to the battery.

[0029] The above technical solution can improve the stability and reliability of the battery and mounting bracket, thereby improving the stability of mounting the battery in the vehicle, and also facilitates the connection between the first connecting part and the battery.

[0030] In some embodiments, the first connection is adapted to be located between the battery and the sidewall of the vehicle underbody longitudinal beam.

[0031] In the above technical solution, since the first connection part is located between the battery and the side wall of the longitudinal beam of the vehicle body, the first connection part can be well hidden, thus protecting the battery and the vehicle body, reducing the probability of the first connection part being eroded by mud and water or damaged by impacts from external objects, thereby improving the connection reliability between the battery and the mounting bracket, and facilitating battery replacement.

[0032] In some embodiments, the first connecting portion includes a plurality of sub-connecting portions, which are adapted to be spaced apart along the length direction of the longitudinal beam of the vehicle floor.

[0033] In the above technical solution, since multiple sub-connecting parts are spaced apart along the length of the vehicle bottom longitudinal beam, more space can be fully utilized to set more sub-connecting parts, thereby improving the connection reliability between the mounting bracket and the battery. Furthermore, multiple sub-connecting parts are less likely to interfere with the battery when connected or disconnected, which is beneficial for battery replacement operations.

[0034] In some embodiments, the first connection portion is adapted to be detachably connected to the battery.

[0035] In the above technical solution, since the first connecting part is adapted to be detachably connected to the battery, the battery can be replaced.

[0036] In some embodiments, the mounting bracket includes a frame and a connecting lock, the connecting lock being assembled to the frame and forming a first connecting part, the connecting lock having a locked state for locking the battery and an unlocked state for releasing the battery.

[0037] In the above technical solution, the first connecting part and the battery can be detachably connected, thereby enabling battery replacement. Furthermore, since the first connecting part is defined by a connecting lock assembled to the frame, different types of connecting locks can be selected or designed to meet the installation requirements of different batteries, simplifying the design and processing of the frame and satisfying the structural and dimensional requirements of the frame itself.

[0038] In some embodiments, at least a portion of the center frame is adapted to be located below the underbody longitudinal beams, and a clearance space with an open top is defined between the center frame and the side frame for circumventing the underbody longitudinal beams.

[0039] In the above technical solution, the mounting bracket can be fitted to the longitudinal beam of the vehicle bottom from bottom to top, thereby simplifying the installation of the mounting bracket to the vehicle body, improving assembly efficiency, and simplifying the processing of the longitudinal beam of the vehicle bottom.

[0040] In some embodiments, the central frame portion and both ends are respectively connected to the lower ends of the side frame portions on both sides.

[0041] The above technical solution simplifies the connection between the side frame and the center frame, and also increases the height of the side frame relative to the longitudinal beam of the vehicle floor, minimizing the space occupied by the side frame below the longitudinal beam of the vehicle floor.

[0042] In some embodiments, the midframe portion has an upper protrusion adapted to extend between the two longitudinal beams of the vehicle floor longitudinal beam, and a cavity formed below the upper protrusion is adapted to accommodate a portion of the battery.

[0043] In the above technical solution, since a portion of the battery can extend into the cavity formed below the upper convex part, and this portion is located between the two longitudinal beams of the vehicle bottom longitudinal beam, the space under the vehicle bottom can be fully utilized to install the battery, thereby increasing the battery capacity.

[0044] In some embodiments, the center frame has an clearance opening that is adapted to be spaced between the two longitudinal beams of the corresponding underbody longitudinal beam.

[0045] In the above technical solution, a portion of the battery can be inserted between the two longitudinal beams of the vehicle undercarriage by avoiding the opening, thereby making full use of the space under the vehicle to install the battery and increasing the battery capacity.

[0046] In some embodiments, the mounting portion includes a second mounting portion disposed on the center frame portion, the second mounting portion being adapted to be connected to the longitudinal beam under the vehicle.

[0047] In the above technical solution, by using the middle frame of the side frame connecting both sides to set up the second mounting part, the connection between the second mounting part and the longitudinal beam of the vehicle floor can be easily realized. By using the longitudinal beam of the vehicle floor to connect the mounting frame, the restrictions on vehicle models can be reduced and the applicability of the mounting frame can be improved.

[0048] In some embodiments, the second mounting portion is adapted to be connected to the bottom wall of the vehicle underbody longitudinal beam by a second fastener extending vertically.

[0049] The above technical solution simplifies the connection between the second mounting part and the longitudinal beam of the vehicle floor, and improves the reliability of the connection. Furthermore, it simplifies the structure and processing of the center frame and the longitudinal beam of the vehicle floor, and improves the tightness of the fit between the center frame and the longitudinal beam of the vehicle floor.

[0050] In some embodiments, the center frame includes two second extensions, which are adapted to be located below the two side longitudinal beams of the vehicle floor longitudinal beam and extend along the length direction of the vehicle floor longitudinal beam. The second extensions are provided with a plurality of second mounting portions, which are adapted to be spaced apart along the length direction of the vehicle floor longitudinal beam.

[0051] In the above technical solution, the connection between the second mounting part and the longitudinal beam of the vehicle bottom is realized, and the connection reliability between the mounting bracket and the vehicle body is improved.

[0052] In some embodiments, the mid-frame section is provided with a docking portion, which is adapted to be located between the two longitudinal beams of the vehicle under the longitudinal beam, and the docking portion is used to dock with the liquid passage and / or electrical circuit on the battery.

[0053] In the above technical solution, since the docking section is located on the central frame, which connects to the side frames on both sides, the central frame has strong stability, which improves the stability of the docking section and enhances the stability and reliability of the docking with the battery. Furthermore, because the docking section is located between the two longitudinal beams of the vehicle's underbody, it is protected by the underbody longitudinal beams, reducing the probability of damage from impacts and mitigating the problem of corrosion failure caused by mud and water, thus improving the reliability and stability of the docking. Moreover, the docking section does not occupy space outside the underbody longitudinal beams, saving space and increasing battery capacity.

[0054] In some embodiments, the bottom wall of the upper protrusion is provided with a docking portion, which is used to dock with the liquid passages and / or circuits on the battery.

[0055] The above technical solution simplifies the installation of the docking part, improves its stability, protects it, reduces the probability of damage from impacts, improves the problem of corrosion failure caused by mud and water, and enhances the reliability and stability of the docking.

[0056] In some embodiments, the mounting bracket includes a baffle disposed around the docking portion.

[0057] In the above technical solution, by setting a baffle on the mounting frame, the mating part can be protected by the baffle, reducing the probability of the mating part being damaged by bumps and collisions, and improving the problem of the mating part failing due to corrosion by mud and water.

[0058] In some embodiments, the mounting bracket has a mating portion for mating with the liquid and / or electrical circuits on the battery.

[0059] In the above technical solution, by setting a docking part on the mounting bracket, the docking requirements of the battery and the vehicle body's circuit and / or fluid circuit can be met through the structural design of the mounting bracket, thereby simplifying the structural design of the vehicle body and the battery.

[0060] In some embodiments, the mating surface of the mating part is arranged vertically downward, or inclined downward, or horizontally.

[0061] The above technical solution facilitates the connection between the battery and the docking part.

[0062] In some embodiments, the mounting bracket includes an integrally formed frame, which constitutes at least a portion of the side frame portion and at least a portion of the middle frame portion.

[0063] The above technical solution can improve the overall structural strength of the mounting bracket, thereby improving the stability and reliability of the battery mounted on the vehicle.

[0064] In some embodiments, the mounting bracket has a connecting portion for connecting the mounting bracket to the battery.

[0065] The above technical solution can improve the stability and reliability of the battery and mounting bracket, thereby improving the stability of mounting the battery in the vehicle.

[0066] In some embodiments, at least a portion of the connection is adapted to be located between the battery and the vehicle body.

[0067] In the above technical solution, at least some of the connection parts are concealed, making them less susceptible to damage from bumps or erosion by mud and water, thereby improving the reliability and stability of the connection between the mounting bracket and the battery, and improving the reliability and stability of the battery mounted on the vehicle.

[0068] In some embodiments, the connection is adapted to be located between the battery and the side wall of the longitudinal beam under the vehicle body.

[0069] In the above technical solution, the connection part is hidden, making it less susceptible to damage from bumps or corrosion from mud and water. Furthermore, the connection part has high precision, which is beneficial for the connection with the battery.

[0070] In some embodiments, at least a portion of the mounting portion is adapted to be located between the battery and the vehicle body.

[0071] In the above technical solution, at least some of the mounting parts are concealed, making them less susceptible to impact damage or corrosion from mud and water, thereby improving the reliability and stability of the connection between the mounting bracket and the vehicle body, and improving the reliability and stability of the battery mounted on the vehicle.

[0072] In some embodiments, at least a portion of the mounting bracket is adapted to be located between the battery and the vehicle body's underbody longitudinal beam, such that at least a portion of the mounting portion is adapted to be connected to the underbody longitudinal beam.

[0073] In the above technical solution, the mounting bracket and the longitudinal beam of the vehicle bottom can be reliably connected, and it can be installed on a variety of vehicle models, making it widely applicable.

[0074] Secondly, embodiments of this application provide a vehicle, including a vehicle body and the aforementioned mounting bracket, the mounting bracket being connected to the vehicle body.

[0075] In some embodiments, the vehicle body includes a longitudinal beam under the vehicle floor, and the vehicle includes a plurality of mounting brackets arranged sequentially along the length of the longitudinal beam under the vehicle floor.

[0076] In the above technical solution, the size of each mounting bracket can be relatively small, which can improve the shape accuracy of each mounting bracket, facilitate the connection between each mounting bracket and the vehicle body, and improve the structural strength of each mounting bracket, thereby improving the stability of the battery mounted on the vehicle.

[0077] In some embodiments, the vehicle also includes a battery that is mounted to the vehicle body via a mounting bracket.

[0078] In some embodiments, the vehicle body includes a longitudinal beam under the vehicle, the battery has a recess with an open top that accommodates the longitudinal beam under the vehicle, the battery includes battery cells disposed below and on both sides of the recess, and a mounting bracket is clamped between the recess and the longitudinal beam under the vehicle.

Detailed Implementation

[0093] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0094] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0095] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0096] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0097] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0098] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0099] In this application, "multiple" means two or more (including two).

[0100] In this application, the battery cell may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application are not limited to these. The battery cell may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited to these. Battery cells are generally divided into three types according to their packaging method: cylindrical battery cells, square battery cells, and pouch battery cells, and the embodiments of this application are not limited to these.

[0101] The battery mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. The battery in the embodiments of this application includes a housing for encapsulating one or more battery cells or multiple battery modules. The battery module is composed of multiple battery cells, and the housing is used to prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0102] In a battery, multiple battery cells can be connected in series, parallel, or a combination thereof. A combination thereof refers to multiple battery cells being connected in both series and parallel configurations. Multiple battery cells can be directly connected in series, parallel, or a combination thereof, and then the entire assembly of these cells is housed within a casing. Alternatively, a battery can consist of multiple battery cells first connected in series, parallel, or a combination thereof to form a battery module, and then these modules are connected in series, parallel, or a combination thereof to form a whole, housed within a casing. Furthermore, a battery can include other structures, such as a busbar component for electrical connection between multiple battery cells. In recent years, new energy vehicles have experienced rapid development. In the field of electric vehicles, batteries, as the power source, play an irreplaceable and crucial role. Inventors have discovered that to integrate batteries into vehicles, either a corresponding mounting structure is typically installed on the vehicle based on the battery's structure and mounting point characteristics to meet the battery's installation requirements, or a corresponding mounting structure is fabricated on the battery based on the vehicle's structure and mounting point characteristics. This either increases the design and manufacturing complexity of the vehicle or the battery itself.

[0103] Based on the above considerations, the inventors, after in-depth research, designed a mounting bracket for mounting batteries to the vehicle body. The mounting bracket has a mounting section for connecting the bracket to the vehicle body. By setting a mounting bracket between the vehicle body and the battery, the battery can be mounted onto the vehicle body. This allows for flexible design of the mounting bracket's shape and structure based on the characteristics of both the vehicle body and the battery, meeting the requirements for battery mounting in vehicles and thus reducing the design and manufacturing complexity of both the battery and the vehicle body.

[0104] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The battery 100 can be used to power the vehicle 1000; for example, the battery 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller and a motor. The controller is used to control the battery 100 to supply power to the motor, for example, to meet the power requirements of the vehicle 1000 during starting, navigation, and driving. In some embodiments of this application, the battery 100 can not only serve as the operating power source for the vehicle 1000 but also as the driving power source for the vehicle 1000, replacing or partially replacing gasoline or natural gas to provide driving power for the vehicle 1000.

[0105] Hereinafter, with reference to the accompanying drawings, a mounting bracket 300 according to an embodiment of the present application will be described.

[0106] like Figures 1-4As shown, the mounting bracket 300 is used to install the battery 100 to the vehicle body 200. The mounting bracket 300 has a mounting part 30 for connecting the mounting bracket 300 to the vehicle body 200.

[0107] It is worth noting that the connection method between the mounting part 30 and the vehicle body 200 is not limited. For example, in some embodiments, the mounting part 30 can be connected to the vehicle body 200 itself, such as by a rivet screw or a clip. In other embodiments, the mounting part 30 can be connected to the vehicle body 200 through a connector, such as a connecting hole or a rivet nut, and can be connected to the vehicle body 200 through a screw, bolt, or other connector.

[0108] It is worth noting that the connection between the mounting bracket 300 and the battery 100 is not limited. For example, in some embodiments, the mounting bracket 300 and the battery 100 can be directly or indirectly connected. In other embodiments, the mounting bracket 300 and the battery 100 may not be connected. For example, the mounting bracket 300 may only support and limit the battery 100 without being connected to the battery 100.

[0109] In the above technical solution, the battery 100 is installed on the vehicle body 200 by setting a mounting bracket 300 between the vehicle body 200 and the battery 100. This allows the mounting bracket 300 to be flexibly designed in terms of shape and structure according to the characteristics of the vehicle body 200 and the battery 100, so as to meet the requirements of connection, load-bearing capacity and space utilization, thereby reducing the design and processing difficulty of the battery 100 and the vehicle body 200 and making it highly adaptable.

[0110] In some embodiments, such as Figure 5 and Figure 6 As shown, the mounting bracket 300 includes two side bracket parts 10 and a central bracket part 20 connecting the two side bracket parts 10. The two side bracket parts 10 are located on both sides of the vertical space where the longitudinal beam 201 of the vehicle bottom of the vehicle body 200 is located.

[0111] It should be noted that the longitudinal direction of the undercarriage beam 201 in this article (e.g., Figure 1 and Figure 2 The first direction X shown is the front-rear direction of the vehicle body 200, and the width direction of the longitudinal beam 201 under the vehicle (e.g., the longitudinal direction of the vehicle body 200). Figure 2 The second direction Y shown is the left-right direction of the vehicle body 200, and the height direction of the longitudinal beam 201 under the vehicle (e.g.) Figure 2 The third direction Z shown in the diagram represents the vertical direction of the vehicle body 200. The longitudinal beam 201 under the vehicle described in this article can also be referred to as the automobile beam.

[0112] The "vertical space where the longitudinal beam 201 is located" refers to the space where the longitudinal beam 201 is located, as well as the space directly below and above it. Therefore, the two side frame parts 10 are located on both sides of the vertical space where the longitudinal beam 201 is located on the vehicle body 200, meaning that the side frame parts 10 are respectively provided on the left and right sides of the vertical space where the longitudinal beam 201 is located. That is, the side frame parts 10 are not required to be at the same height as the longitudinal beam 201. For example, the side frame parts 10 can be at the same height as the longitudinal beam 201, or the side frame parts 10 can be lower than the longitudinal beam 201, as long as the side frame parts 10 are located on the left and right sides of the vertical space where the longitudinal beam 201 is located.

[0113] In the above technical solution, since the mounting bracket 300 includes a side bracket portion 10 and a middle bracket portion 20, the mounting bracket 300 has good structural strength and strong load-bearing capacity for the battery 100, which can improve the stability of the battery 100 mounted on the vehicle 1000. Moreover, since the mounting bracket 300 includes side bracket portions 10 located on both sides of the vertical space where the longitudinal beam 201 of the vehicle bottom is located, the mounting bracket 300 can make full use of the space under the vehicle bottom, which is beneficial for supporting a battery 100 with a larger capacity.

[0114] In some embodiments, such as Figure 1 , Figures 5-7 As shown, at least a portion of the side frame portion 10 is higher than the lower end of the undercarriage longitudinal beam 201, so that at least a portion of the side frame portion 10 can be located to the side of the undercarriage longitudinal beam 201.

[0115] It should be noted that "the side of the longitudinal beam 201 under the vehicle" in this article refers to the left or right side of the longitudinal beam 201 under the vehicle at its horizontal height.

[0116] In the above technical solution, since the side frame part 10 is not lower than the bottom of the vehicle bottom longitudinal beam 201 as a whole, it is advantageous to use the horizontal space on both sides of the vehicle bottom longitudinal beam 201 to set up the side frame part 10, or even to set up the battery 100, thereby improving the space utilization rate.

[0117] In some embodiments, such as Figure 1 , Figures 5-7 As shown, at least a portion of the side frame 10 is located between the vehicle body 200 and the battery 100. That is, the side frame 10 may be located only partially between the vehicle body 200 and the battery 100, or the side frame 10 may be located entirely between the vehicle body 200 and the battery 100.

[0118] In the above technical solution, since at least part of the side frame 10 is higher than the lower end of the longitudinal beam 201 and located between the vehicle body 200 and the battery 100, it can be well hidden and not directly exposed to the outside, so as to obtain the protection of the battery 100 and the vehicle body 200, reduce the probability of this part being eroded by mud and water or damaged by impacts from external objects, and thus improve the stability of the battery 100 mounted on the vehicle 1000.

[0119] When the side frame 10 is entirely located between the vehicle body 200 and the battery 100, the entire side frame 10 can be protected by the battery 100 and the vehicle body 200, reducing the probability of the side frame 10 being corroded by mud and water or damaged by impacts from external objects, thereby improving the stability of the battery 100 mounted on the vehicle 1000.

[0120] In some embodiments, such as Figures 2-5 As shown, the side frame portion 10 is along the length direction of the longitudinal beam 201 of the vehicle floor (e.g., Figure 1 and Figure 2 As shown, it extends in the first direction (X), and the side frame portion 10 is sandwiched between the battery 100 and the side wall of the vehicle underbody longitudinal beam 201.

[0121] In the above technical solution, by setting the side frame portion 10 to extend along the length direction of the vehicle floor longitudinal beam 201, the side frame portion 10 can be sandwiched between the battery 100 and the side wall of the vehicle floor longitudinal beam 201. This allows the side frame portion 10 to be protected by the battery 100 and the vehicle floor longitudinal beam 201, reducing the probability of the side frame portion 10 being corroded by mud and water or damaged by impacts from external objects, and improving the stability of the battery 100 mounted on the vehicle 1000. Moreover, the side frame portion 10 has a smaller dimension in the width direction of the vehicle floor longitudinal beam 201, reducing the risk of breakage of the side frame portion 10 and the risk of breakage at the connection between the side frame portion 10 and the center frame portion 20, thereby improving the structural reliability of the mounting bracket 300.

[0122] Of course, this application is not limited to this. In other embodiments of this application, the side frame portion 10 may also be configured to extend in other directions, for example, at least a portion of the side frame portion 10 may extend along the width direction of the longitudinal beam 201 of the vehicle floor (e.g. Figure 2 The second direction (Y) shown in the figure extends, or extends obliquely in the width direction of the longitudinal beam 201 of the vehicle bottom, etc. In addition, in other embodiments of this application, the side frame portion 10 may also be clamped between the battery 100 and other positions of the vehicle body 200, such as clamped between the battery 100 and the chassis on both sides of the longitudinal beam 201 of the vehicle bottom, etc., which will not be described in detail here.

[0123] In some embodiments, the mounting portion 30 includes a first mounting portion 31 provided on the side frame portion 10. That is, at least one side frame portion 10 is provided with a first mounting portion 31, which is used to connect the mounting bracket 300 to the vehicle body 200.

[0124] In the above technical solution, since the side frame part 10 is located on both sides of the vertical space where the vehicle bottom longitudinal beam 201 is located, the first mounting part 31 is set on the side frame part 10, indicating that the first mounting part 31 can also be located on the outside (left and / or right) of the vehicle bottom longitudinal beam 201. The space here is relatively sufficient, which facilitates the connection between the first mounting part 31 and the vehicle body 200 on the one hand, and facilitates the flexible design of the first mounting part 31 on the other hand.

[0125] In some embodiments, such as Figures 2-4 As shown, the side frame portion 10 includes a first extension portion 11 extending along the length direction of the vehicle floor longitudinal beam 201 and sandwiched between the battery 100 and the side wall of the vehicle floor longitudinal beam 201. A first mounting portion 31 is provided on the first extension portion 11 and is adapted to be connected to the side wall of the vehicle floor longitudinal beam 201. In this embodiment, at least a portion of the side frame portion 10 is the first extension portion 11. When the entire side frame portion 10 is the first extension portion 11, the side frame portion 10 extends along the length direction of the vehicle floor longitudinal beam 201 and is sandwiched between the battery 100 and the vehicle floor longitudinal beam 201.

[0126] In the above technical solution, since the first mounting part 31 is provided on the first extension 11 sandwiched between the battery 100 and the vehicle bottom longitudinal beam 201, the first mounting part 31 can also be easily hidden and protected by the battery 100 and the vehicle bottom longitudinal beam 201, thereby improving the connection reliability between the first mounting part 31 and the vehicle bottom longitudinal beam 201.

[0127] In some embodiments, the first mounting portion 31 is connected to the side wall of the longitudinal beam 201 of the vehicle floor via a first fastener extending laterally. The specific type of the first fastener is not limited; for example, it can be a screw, bolt, rivet, etc.

[0128] In the above technical solution, since the first extension 11 is sandwiched between the battery 100 and the vehicle bottom longitudinal beam 201, the first mounting part 31 is connected to the side wall of the vehicle bottom longitudinal beam 201 by using the first fastener that extends laterally. The characteristics of the relative positional relationship between the first extension 11 and the vehicle bottom longitudinal beam 201 can be utilized to simplify the connection between the first mounting part 31 and the vehicle body 200 and improve the reliability of the connection between the first mounting part 31 and the vehicle body 200.

[0129] Furthermore, this connection method only requires drilling holes or installing nuts on the side walls of the first extension 11 and the longitudinal beam 201, eliminating the need for complex connecting seats or those requiring adjustment of the connection direction. This simplifies the structure and manufacturing of the first extension 11 and the longitudinal beam 201. Moreover, it improves the tightness of the fit between the first extension 11 and the longitudinal beam 201, saving space and facilitating the installation of a battery 100 with a larger capacity.

[0130] In some embodiments, such as Figures 2-4 As shown, the first extension 11 is provided with a plurality of first mounting portions 31 spaced apart along the length direction of the longitudinal beam 201 of the vehicle floor. In the above technical solution, since the plurality of first mounting portions 31 are spaced apart along the length direction of the longitudinal beam 201 of the vehicle floor, the space of the first extension 11 can be fully utilized, and a larger number of first mounting portions 31 can be provided, which improves the connection reliability between the mounting bracket 300 and the vehicle body 200. Furthermore, the plurality of first mounting portions 31 are less likely to interfere with the connection when connected to the longitudinal beam 201 of the vehicle floor, which is beneficial to the connection operation.

[0131] In some embodiments, such as Figure 5 As shown, the mounting bracket 300 includes a frame 40 and mounting ears 33. The mounting ears 33 are assembled to the frame 40 and define a first mounting portion 31.

[0132] In the above technical solution, since the first mounting part 31 is defined by the mounting ear 33 assembled to the frame 40, the design and processing requirements of the first mounting part 31 can be met by adjusting the shape and size of the mounting ear 33, which simplifies the design and processing of the frame 40 and meets the structural and dimensional requirements of the frame 40 itself.

[0133] It is worth noting that the structure of the frame 40 is not limited. For example, a part of the frame 40 can be at least part of the side frame 10, and the rest of the frame 40 can be at least part of the middle frame 20.

[0134] Of course, this application is not limited to this. For example, in other embodiments of this application, the first mounting part 31 can be directly machined on the frame 40, thereby reducing the assembly process.

[0135] In some embodiments, such as Figure 5 As shown, the mounting ear 33 is detachably connected to the frame 40. For example, if the mounting ear 33 is damaged or dirty, it can be removed for cleaning or replacement. Furthermore, if the mounting ear 33 is available in various sizes, different mounting ears can be used to adapt to the installation requirements of different vehicle models.

[0136] In some embodiments, such as Figure 5 As shown, the mounting bracket 300 also includes a gasket, which is detachably disposed between the mounting ear 33 and the bracket body 40. Therefore, depending on the actual vehicle model and the specific mounting points on the vehicle body 200, it is possible to choose whether to install a gasket, or to select the type of gasket, thus adapting to the installation requirements of different vehicle models.

[0137] For example, when the side frame portion 10 includes a first extension portion 11 extending along the length direction of the vehicle bottom longitudinal beam 201 and sandwiched between the battery 100 and the vehicle bottom longitudinal beam 201, and the first mounting portion 31 is provided on the first extension portion 11 and is adapted to be connected to the side wall of the vehicle bottom longitudinal beam 201, by providing shims of different specifications between the mounting ear 33 and the frame body 40, the mounting of vehicle bottom longitudinal beams 201 of different widths can be adapted, thereby improving the applicability of the mounting frame 300.

[0138] In some embodiments, such as Figure 5 As shown, each side frame portion 10 has a first mounting portion 31. Therefore, the mounting bracket 300 can be connected to the vehicle body 200 on both sides of the longitudinal beam 201 under the vehicle, thereby improving the reliability of the connection between the mounting bracket 300 and the vehicle body 200, and further improving the stability of mounting the battery 100 on the vehicle 1000.

[0139] It is worth noting that the structures of the first mounting parts 31 on the two side frame parts 10 can be the same or different, and the positions of the first mounting parts 31 on the two side frame parts 10 can be symmetrical or staggered. No restrictions or details are provided here.

[0140] In some embodiments, such as Figure 5 As shown, the mounting portion 30 includes a first connecting portion 50 provided on the side frame portion 10. The first connecting portion 50 is used to connect the mounting bracket 300 and the battery 100. That is, at least one side frame portion 10 has a first connecting portion 50, and the battery 100 is directly or indirectly connected to the first connecting portion 50 to realize the connection between the battery 100 and the mounting bracket 300.

[0141] In the above technical solution, by providing the first connecting part 50 to connect the battery 100, the stability and reliability of the cooperation between the battery 100 and the mounting bracket 300 can be improved, thereby improving the stability of mounting the battery 100 on the vehicle 1000. Furthermore, by providing the first connecting part 50, the mounting bracket 300 can mount the battery 100 without necessarily setting it to a bracket form that supports the battery 100. Of course, the mounting bracket 300 can also be set to a bracket form that supports the battery 100, thus enabling flexible configuration of the mounting bracket 300.

[0142] In addition, by placing the first connecting part 50 on the side frame part 10, since the side frame part 10 is located on both sides of the vertical space where the vehicle bottom longitudinal beam 201 is located, the first connecting part 50 can also be located on the outside (left and / or right) of the vehicle bottom longitudinal beam 201. The space here is relatively sufficient, which facilitates the connection between the first connecting part 50 and the battery 100 on the one hand, and facilitates the flexible design of the first connecting part 50 on the other hand.

[0143] In some embodiments, such as Figures 5-7As shown, the first connecting part 50 is located between the battery 100 and the side wall of the longitudinal beam 201 of the vehicle body 200.

[0144] In the above technical solution, since the first connecting part 50 is located between the battery 100 and the side wall of the longitudinal beam 201 of the vehicle body 200, the first connecting part 50 can be well hidden, thus protecting the battery 100 and the vehicle body 200, reducing the probability of the first connecting part 50 being eroded by mud and water or damaged by impacts from external objects, thereby improving the connection reliability between the battery 100 and the mounting bracket 300, and also facilitating the replacement of the battery 100.

[0145] Furthermore, since the first connecting part 50 is located between the battery 100 and the side wall of the longitudinal beam 201 of the vehicle body 200, the first connecting part 50 is close to the longitudinal beam 201. The deformation of the mounting bracket 300 at the position of the first connecting part 50 is relatively small, which can improve the positional accuracy of the first connecting part 50. Moreover, when the first connecting part 50 is provided on both sides of the longitudinal beam 201, the relative distance between the first connecting parts 50 on both sides of the longitudinal beam 201 is closer, and the relative positional accuracy of the first connecting parts 50 on both sides is higher. This makes it easier to align and connect the battery 100 with the first connecting part 50, thereby improving the assembly efficiency of the battery 100.

[0146] In some related technologies, mounting brackets used to install batteries onto vehicles employ battery swapping locks arranged around the battery. These locks are exposed, and during vehicle operation, mud, splashes of water, etc., can adversely affect them. After a period of operation, corrosion of the locks often renders them unusable for battery swapping. Furthermore, because the locks are positioned around the battery, the span between them is large, and the mounting bracket at the lock locations experiences relatively significant deformation, resulting in low fitting precision and impacting swapping efficiency. In some embodiments of this application, by placing all connecting parts between the battery 100 and the side wall of the vehicle's underbody longitudinal beam 201, the aforementioned technical problems can be effectively solved.

[0147] When the first connecting portion 50 is located between the battery 100 and the side wall of the longitudinal beam 201 of the vehicle body 200, in some embodiments, such as Figures 5-7 As shown, the first connecting portion 50 includes a portion along the length direction of the longitudinal beam 201 of the vehicle floor (e.g., Figure 1 and Figure 2 The first direction X) shown in the figure has a plurality of sub-connecting parts 51 spaced apart.

[0148] In the above technical solution, when the first connecting part 50 is located between the battery 100 and the side wall of the longitudinal beam 201 of the vehicle body 200, since multiple sub-connecting parts 51 are spaced apart along the length direction of the longitudinal beam 201, more space can be fully utilized, more sub-connecting parts 51 can be set, the connection reliability between the mounting bracket 300 and the battery 100 can be improved, and multiple sub-connecting parts 51 are less likely to interfere with the battery 100 when connected or disconnected, which is beneficial to the battery 100 replacement operation.

[0149] In some embodiments, the first connecting part 50 and the battery 100 may be detachably connected, thereby enabling the battery 100 to be replaced.

[0150] For example Figures 5-7 As shown, the mounting bracket 300 may include a bracket body 40 and a connecting lock 52. The connecting lock 52 is mounted on the bracket body 40 and constitutes a first connecting part 50. The connecting lock 52 has a locked state for locking the battery 100 and an unlocked state for releasing the battery 100. Thus, the first connecting part 50 and the battery 100 can be detachably connected, thereby enabling the replacement of the battery 100.

[0151] In the above technical solution, since the first connecting part 50 is defined by the connecting lock 52 assembled to the frame 40, different types of connecting locks 52 can be selected or designed to meet the installation requirements of different batteries 100, simplifying the design and processing of the frame 40 and meeting the structural and dimensional requirements of the frame 40 itself.

[0152] It is worth noting that the structure of the frame 40 is not limited. For example, a part of the frame 40 can be at least part of the side frame 10, and the rest of the frame 40 can be at least part of the middle frame 20.

[0153] Of course, this application is not limited to this. For example, in other embodiments of this application, the first connecting part 50 can be directly machined on the frame 40, thereby reducing the assembly process.

[0154] It should be noted that the specific structure and form of the connecting lock 52 are not limited; for example, it can be a snap-lock or a bolt lock. For instance, when the connecting lock 52 is a snap-lock, such as... Figure 5 As shown, the connecting lock 52 is housed within the frame 40, which has a hanging hole with an open bottom. The battery 100 may have a mounting pin, which is adapted to extend upward into the hanging hole and lock into the connecting lock 52, thereby facilitating the assembly of the battery 100 with the mounting bracket 300. Alternatively, if the connecting lock 52 is a bolt lock, it can be a bolt or nut extending vertically in the axial direction, adapted to engage with the nut or bolt on the battery 100, thus facilitating the assembly of the battery 100 with the mounting bracket 300. Further details are omitted here.

[0155] For example, the frame 40 may include two sheet metal parts welded together, with a storage cavity defined between the two sheet metal parts. The connecting lock 52 is set in the storage cavity. One sheet metal part has a fixing point and a hanging hole, and the other sheet metal part has a mounting part 30. The connecting lock 52 can be fixed to the fixing point using fasteners such as bolts. Then, the sheet metal part is welded to the other sheet metal part, and then the mounting bracket 300 is installed to the vehicle body 200 through the mounting part 30. Thus, the structure of the frame 40 is simple, and the position of the connecting lock 52 is concealed, which can improve the reliability of the connecting lock 52 and the effectiveness of battery swapping.

[0156] In addition, a water-blocking component, such as a waterproof curtain, can be installed at the hanging hole position. When the padlock pin is inserted into the hanging hole, the waterproof curtain can be opened, and when the padlock pin is removed from the hanging hole, the waterproof curtain can return to the state of blocking the hanging hole, thereby achieving a waterproof effect and further protecting the connecting lock 52.

[0157] In some embodiments, such as Figures 5-7 As shown, each side frame portion 10 has a first connecting portion 50. Therefore, the mounting bracket 300 and the battery 100 can be connected on both sides of the longitudinal beam 201 under the vehicle floor, thereby improving the reliability of the connection between the mounting bracket 300 and the battery 100, and further improving the stability of mounting the battery 100 on the vehicle 1000.

[0158] Of course, this application is not limited to this. For example, in other embodiments of this application, the mounting bracket 300 may also have other connecting parts for connecting the mounting bracket 300 and the battery 100, such as a second connecting part that extends into the interior of the longitudinal beam 201 of the vehicle floor, etc., which will not be described in detail here.

[0159] It is worth noting that the structures of the first connecting parts 50 on the two side frame parts 10 can be the same or different, and the positions of the first connecting parts 50 on the two side frame parts 10 can be symmetrical or staggered. No restrictions or details are provided here.

[0160] In some embodiments, such as Figures 5-7 As shown, at least a portion of the center frame 20 is located below the underbody longitudinal beam 201, and a clearance space 21 with an open top and used to avoid the underbody longitudinal beam 201 is defined between the center frame 20 and the side frame 10.

[0161] In the above technical solution, the mounting bracket 300 can be fitted to the longitudinal beam 201 from bottom to top, thereby simplifying the installation of the mounting bracket 300 onto the vehicle body 200, improving assembly efficiency, and simplifying the processing of the longitudinal beam 201. Furthermore, at least a portion of the side frame portion 10 can be higher than the lower end of the longitudinal beam 201, which facilitates the use of the horizontal space on both sides of the longitudinal beam 201 to install the side frame portion 10, and even the battery 100, thereby improving space utilization.

[0162] In some embodiments, such as Figure 5 and Figure 6 As shown, the middle frame 20 is connected to the lower ends of the side frame 10 on both sides.

[0163] In the above technical solution, on the one hand, it is beneficial to connect the side frame part 10 and the middle frame part 20, so that at least part of the side frame part 10 and at least part of the middle frame part 20 can be integrally formed, thereby improving the connection strength between the two. On the other hand, it is beneficial to increase the height of the side frame part 10 relative to the vehicle bottom longitudinal beam 201, so as to minimize the space occupied by the side frame part 10 in the vertical direction below the vehicle bottom longitudinal beam 201, thereby making use of the saved space to install the battery 100.

[0164] Of course, this application is not limited to this. The two ends of the middle frame portion 20 can also be connected to other positions of the side frame portion 10. For example, in other embodiments, the two ends of the middle frame portion 20 can also be connected to the upper end or middle of the side frame portion 10, etc., which will not be elaborated here. In addition, at least a portion of the side frame portion 10 and at least a portion of the middle frame portion 20 do not have to be integrally formed. For example, the side frame portion 10 and the middle frame portion 20 can be separate frames and assembled together, which is not limited here.

[0165] In some embodiments, such as Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the middle frame 20 has an upper protrusion 22 that extends between the two longitudinal beams 202 of the vehicle bottom longitudinal beam 201. The cavity formed below the upper protrusion 22 is suitable for accommodating a portion of the battery 100.

[0166] In the above technical solution, a portion of the battery 100 can extend into the cavity formed below the upper protrusion 22. This portion is located between the two longitudinal beams 202 on both sides of the vehicle undercarriage longitudinal beam 201, thereby making full use of the space under the vehicle to install the battery 100 and increasing the battery capacity of the battery 100.

[0167] In some embodiments, such as Figure 2 , Figure 5 , Figure 8 and Figure 9 As shown, the middle frame 20 has an clearance opening 23, which corresponds to the space between the two longitudinal beams 202 on both sides of the undercarriage longitudinal beam 201.

[0168] In the above technical solution, a portion of the battery 100 can extend into the space between the two longitudinal beams 202 of the vehicle undercarriage longitudinal beam 201 through the clearance opening 23, thereby making full use of the space under the vehicle to install the battery 100 and increasing the battery capacity of the battery 100. Moreover, the clearance opening 23 is easy to manufacture and has low cost.

[0169] In some embodiments, such as Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the middle frame 20 has an upper protrusion 22 and a clearance opening 23. At this time, a portion of the battery 100 can extend into the recess formed below the upper protrusion 22 through the clearance opening 23, so as to be located between the two longitudinal beams 202 on both sides of the vehicle under longitudinal beam 201. This allows the battery 100 to be installed in the vehicle under space in a way that can be fully utilized, thereby increasing the battery capacity of the battery 100.

[0170] For example, the middle frame portion 20 includes a first sub-frame 24 and a second sub-frame 25. The two ends of the first sub-frame 24 are respectively connected to the lower ends of the two side frame portions 10. The two ends of the second sub-frame 25 are respectively connected to the two ends of the first sub-frame 24. The second sub-frame 25 protrudes upward relative to the first sub-frame 24, forming an upper protrusion 22. An avoidance opening 23 is formed on the first sub-frame 24 and corresponds to the cavity below the upper protrusion 22. Therefore, the middle frame portion 20 has a simple structure and is easy to manufacture. Of course, this application is not limited to this; in other embodiments of this application, the middle frame portion 20 can also be configured as a one-piece molded part, etc., and no limitation is made here.

[0171] In some embodiments, such as Figure 5 As shown, the mounting section 30 includes a second mounting section 32 provided in the center frame section 20, and the second mounting section 32 is adapted to be connected to the undercarriage longitudinal beam 201.

[0172] In the above technical solution, by using the middle frame portion 20 of the side frame portion 10 connecting both sides to set the second mounting portion 32, the connection between the second mounting portion 32 and the vehicle bottom longitudinal beam 201 can be easily realized. By using the vehicle bottom longitudinal beam 201 to connect the mounting bracket 300, the restriction on vehicle models can be reduced and the applicability of the mounting bracket 300 can be improved.

[0173] Furthermore, when the mounting part 30 includes both the first mounting part 31 and the second mounting part 32, the mounting bracket 300 can be connected to the vehicle body 200 from different positions, thereby improving the reliability of the connection between the mounting bracket 300 and the vehicle body 200.

[0174] In some embodiments, the second mounting portion 32 is connected to the bottom wall of the longitudinal beam 201 of the vehicle floor via a second fastener extending vertically. The specific type of the second fastener is not limited; for example, it can be a screw, bolt, rivet, etc.

[0175] In the above technical solution, by using a second fastener that extends vertically to connect the second mounting part 32 to the bottom wall of the vehicle bottom longitudinal beam 201, the connection between the second mounting part 32 and the vehicle bottom longitudinal beam 201 can be simplified by taking advantage of the relative positional relationship between the center frame part 20 and the vehicle bottom longitudinal beam 201, and the connection reliability between the second mounting part 32 and the vehicle bottom longitudinal beam 201 can be improved.

[0176] Furthermore, this connection method only requires drilling holes or installing nuts on the bottom walls of the center frame 20 and the undercarriage longitudinal beam 201, eliminating the need for complex connecting seats or those requiring adjustment of the connection direction. This simplifies the structure and manufacturing of the center frame 20 and the undercarriage longitudinal beam 201. Moreover, it improves the compactness of the fit between the center frame 20 and the undercarriage longitudinal beam 201, saving space and facilitating the installation of batteries 100 with larger capacities.

[0177] In some embodiments, such as Figure 5 and Figure 6 As shown, the center frame 20 includes a second extension 26 located below the two side longitudinal beams 202 of the undercarriage longitudinal beam 201 and extending along the length direction of the undercarriage longitudinal beam 201. The second extension 26 is provided with a plurality of second mounting portions 32 spaced apart along the length direction of the undercarriage longitudinal beam 201. In other words, a second extension 26 is provided below the two side longitudinal beams 202 of the undercarriage longitudinal beam 201, and each second extension 26 is provided with a plurality of second mounting portions 32, so that the second mounting portions 32 can be connected to the bottom surface of each side longitudinal beam 202.

[0178] In the above technical solution, utilizing the structural characteristics of the vehicle underbody longitudinal beam 201, second extensions 26 are respectively provided below the two side longitudinal beams 202 of the vehicle underbody longitudinal beam 201, and second mounting parts 32 are provided on the second extensions 26. This allows for easy connection between the second mounting parts 32 and the two side longitudinal beams 202 of the vehicle underbody longitudinal beam 201. Furthermore, since multiple second mounting parts 32 are spaced apart along the length of the vehicle underbody longitudinal beam 201, the space of the second extensions 26 can be fully utilized, allowing for a greater number of second mounting parts 32. This improves the connection reliability between the mounting bracket 300 and the vehicle body 200. Additionally, the multiple second mounting parts 32 are less likely to interfere with the connection with the vehicle underbody longitudinal beam 201, facilitating the connection operation. Moreover, since the second extensions 26 on both sides are provided with second mounting parts 32, the connection reliability between the mounting bracket 300 and the vehicle underbody longitudinal beam 201 is improved, thereby enhancing the stability of mounting the battery 100 on the vehicle 1000.

[0179] In some embodiments, a portion of the battery 100 may be located below the longitudinal beam 201 of the vehicle floor. In this case, the second mounting portion 32 may be sandwiched between the battery 100 and the longitudinal beam 201 of the vehicle floor, thereby making it easy for the second mounting portion 32 to be hidden and protected by the battery 100 and the longitudinal beam 201 of the vehicle floor, and improving the connection reliability between the second mounting portion 32 and the longitudinal beam 201 of the vehicle floor.

[0180] Of course, this application is not limited to this. In other embodiments of this application, the second mounting part 32 can be connected to other positions of the longitudinal beam 201 through structural matching design of the underbody longitudinal beam 201 and the center frame part 20. For example, a crossbeam 203 connecting the two longitudinal beams 202 on both sides of the underbody longitudinal beam 201 can be provided, and the second mounting part 32 can be located below the crossbeam 203 and connected to the bottom surface of the crossbeam 203. Alternatively, the second mounting part 32 can also be connected to the inner side of the longitudinal beam 202 or the front and rear end faces of the crossbeam 203, etc., which will not be elaborated here.

[0181] In some embodiments, such as Figure 8 and Figure 10 As shown, the mounting bracket 300 has a docking part 60 for docking with the liquid passages and / or electrical circuits on the battery 100.

[0182] In the above technical solution, the mounting bracket 300 can connect to the electrical and / or fluid circuits on the vehicle body 200. A docking part 60 is provided on the mid-frame 20 to connect to the fluid and / or electrical circuits on the battery 100, thereby enabling current conduction, fluid conduction, or both between the vehicle body 200 and the battery 100. For example, when the docking part 60 enables current conduction, it can be used for current transfer between the vehicle 1000 and the battery 100, enabling the battery 100 to supply power to the vehicle 1000 and the vehicle 100 to control the battery 100. Similarly, when the docking part 60 enables fluid conduction, it can be used for heat transfer between the vehicle 1000's refrigerant system and the battery 100, thereby using the refrigerant system to regulate the temperature of the battery 100, improving the reliability and safety of the battery 100. Alternatively, the refrigerant system can absorb the waste heat from the battery 100 to meet the heat source requirements of the vehicle 1000's heat pump air conditioning system, etc., which will not be elaborated further here.

[0183] Therefore, by providing a docking part 60 on the mounting bracket 300, the docking requirements of the battery 100 and the vehicle body 200 can be met by designing the structure of the mounting bracket 300, thereby simplifying the structural design of the vehicle body 200 and the battery 100.

[0184] For example, in some embodiments, such as Figure 8 and Figure 10 As shown, the docking part 60 may include a first docking structure and a second docking structure. The first docking structure is used to dock with the circuit on the battery 100, and the second docking structure is used to dock with the liquid circuit on the battery 100. The relative positions of the first docking structure and the second docking structure are not limited; for example, they can be spaced apart horizontally, left-right, or front-back, so that the first docking structure and the second docking structure do not interfere with each other when docking separately.

[0185] It should be noted that the location of the docking part 60 is not limited and can be selected according to the shape of the mounting bracket 300.

[0186] For example, in some embodiments, such as Figure 8 and Figure 10 As shown, when the mounting bracket 300 includes side bracket portions 10 located on both sides of the vertical space where the longitudinal beam 201 of the vehicle body 200 is located, and a central bracket portion 20 connecting the side bracket portions 10 on both sides, the mating portion 60 can be provided on the central bracket portion 20, and combined with... Figure 3 and Figure 4 The docking part 60 is suitable for being located between the two longitudinal beams 202 on both sides of the longitudinal beam 201 of the vehicle bottom.

[0187] In the above technical solution, since the docking part 60 is located on the central frame part 20, which connects to the side frame parts 10 on both sides, the central frame part 20 has strong stability, which can improve the stability of the docking part 60 and enhance the stability and reliability of the docking between the docking part 60 and the battery 100. Furthermore, since the docking part 60 is located between the two longitudinal beams 202 of the vehicle undercarriage longitudinal beam 201, it is protected by the vehicle undercarriage longitudinal beam 201, reducing the probability of the docking part 60 being damaged by impacts, improving the problem of corrosion failure caused by mud and water, increasing the reliability and stability of the docking, and reducing the risk of electrical failures caused by mud and splashing water erosion. Moreover, the docking part 60 does not need to occupy space outside the vehicle undercarriage longitudinal beam 201, which helps save space and increase the capacity of the battery 100. Furthermore, placing the docking part 60 on the central frame part 20 does not interfere with the cooperation between the mounting bracket 300 and the vehicle undercarriage longitudinal beam 201, which is beneficial for the assembly of the mounting bracket 300 to the vehicle body 200.

[0188] like Figure 8 and Figure 10 As shown, the frame portion 20 has an upper protrusion 22 that extends between the two longitudinal beams 202 of the vehicle floor longitudinal beam 201. When the cavity formed below the upper protrusion 22 is suitable for accommodating a portion of the battery 100, the docking portion 60 can be provided on the bottom wall of the upper protrusion 22. Therefore, the docking portion 60 can be easily positioned between the two longitudinal beams 202 of the vehicle floor longitudinal beam 201, thus simplifying the installation of the docking portion 60.

[0189] For example, combining Figure 8As shown, the middle frame 20 includes a first sub-frame 24 and a second sub-frame 25. The two ends of the first sub-frame 24 are respectively connected to the lower ends of the two side frame parts 10. The two ends of the second sub-frame 25 are respectively connected to the two ends of the first sub-frame 24. The second sub-frame 25 protrudes upward relative to the first sub-frame 24 and forms an upper protrusion 22. The first sub-frame 24 has an avoidance opening 23. When the avoidance opening 23 is arranged in the space between the two longitudinal beams 202 of the vehicle bottom longitudinal beam 201, the docking structure on the battery 100 is suitable to extend into the cavity formed below the upper protrusion 22 through the avoidance opening 23.

[0190] In some embodiments, such as Figure 8 As shown, the mounting bracket 300 includes a baffle 251 disposed around the docking portion 60, where "around" refers to the horizontal periphery, such as the left and right sides, or the front and rear sides. Therefore, by providing the baffle 251 on the mounting bracket 300, the docking portion 60 is protected by the baffle 251, reducing the probability of the docking portion 60 being damaged by impacts and mitigating the problem of corrosion failure caused by mud and water.

[0191] The arrangement of the baffle 251 is not limited. For example, the baffle 251 can be part of the middle frame portion 20. Furthermore, the baffle 251 can be integrally formed with the upper protrusion 22. Alternatively, in other embodiments of this application, the baffle 251 can also be installed on the side frame portion 10 or the middle frame portion 20 by assembly, which is not limited here.

[0192] Of course, this application is not limited to this. In other embodiments of this application, when the mounting bracket 300 is in other forms, the docking part 60 can also be set in other positions of the mounting bracket 300. For example, the docking part 60 can be set on both sides of the longitudinal beam 201 of the vehicle bottom, etc., which will not be elaborated here.

[0193] In some embodiments, the mating surface of the mating portion 60 can be vertically downward. Therefore, as the battery 100 is raised, the mating portion 60 and the battery 100 can be mated together, facilitating the connection between the battery 100 and the mating portion 60. Furthermore, this mating method saves space for the movement of the battery 100.

[0194] In some embodiments, the mating surface of the mating portion 60 may be tilted downwards. Thus, as the battery 100 tilts upwards, the mating portion 60 and the battery 100 can be mated and engaged, thereby facilitating the mating of the battery 100 and the mating portion 60.

[0195] In some embodiments, the mating surface of the mating part 60 can be horizontally arranged. Thus, as the battery 100 is first lifted upward and then moved horizontally, the mating part 60 and the battery 100 can be mated and engaged, thereby facilitating the mating of the battery 100 and the mating part 60.

[0196] When the mounting bracket 300 includes side bracket portions 10 located on both sides of the vertical space where the longitudinal beam 201 of the vehicle body 200 is located, and a middle bracket portion 20 connecting the side bracket portions 10 on both sides, in some embodiments, the mounting bracket 300 may include an integrally formed frame, which constitutes at least a portion of the side bracket portion 10 and at least a portion of the middle bracket portion 20, thereby improving the overall structural strength of the mounting bracket 300, which is beneficial to improving the stability and reliability of the battery 100 mounted on the vehicle 1000.

[0197] Of course, this application is not limited to this. In other embodiments of this application, the side frame part 10 and the middle frame part 20 can also be set as separate structures and assembled and connected, which will not be elaborated here.

[0198] It should be noted that the form of the mounting bracket 300 is not limited to this. For example, the mounting bracket 300 may not be constructed in a shape that spans across the longitudinal beam 201 of the vehicle floor. For example, the mounting bracket 300 may be located entirely on the left side of the longitudinal beam 201 of the vehicle floor, or entirely on the right side of the longitudinal beam 201 of the vehicle floor, or entirely below the longitudinal beam 201 of the vehicle floor, etc., which will not be elaborated here.

[0199] In some embodiments of this application, the mounting bracket 300 has a connecting portion for connecting the mounting bracket 300 to the battery 100. The battery 100 and the connecting portion can be directly or indirectly connected to achieve the connection between the battery 100 and the mounting bracket 300.

[0200] In the above technical solution, by providing a connecting part to connect the battery 100, the stability and reliability of the cooperation between the battery 100 and the mounting bracket 300 can be improved, thereby improving the stability of mounting the battery 100 on the vehicle 1000. Furthermore, by providing the connecting part, the mounting bracket 300 can mount the battery 100 without necessarily having to be configured as a bracket supporting the battery 100. Of course, it can also be configured as a bracket supporting the battery 100, thus allowing for flexible configuration of the mounting bracket 300. It is understandable that if the bracket is tray-shaped, supporting the bottom of the battery and surrounding it, the bracket would occupy relatively more space.

[0201] It is worth noting that the location of the connecting part on the mounting bracket 300 is not limited. It can be specifically selected according to the structural characteristics of the mounting bracket 300 and its matching position with the vehicle body 200. For example, when the mounting bracket 300 is in the form of the above-mentioned side frame part 10 and center frame part 20, the connecting part may include the first connecting part 50 and / or the second connecting part mentioned above, but this application is not limited to this.

[0202] In some embodiments of this application, the connecting part and the battery 100 can be detachably connected. The structure of the connecting part is not limited; for example, it can be a snap-fit ​​lock or locking pin, or a threaded bolt or nut, etc., and no limitation is made here. In the above technical solution, since the connecting part and the battery 100 are detachably connected, the battery 100 can be replaced.

[0203] In some embodiments, at least a portion of the connection is located between the battery 100 and the vehicle body 200. Therefore, the location of at least a portion of the connection is concealed, making it less susceptible to damage from impacts or corrosion from mud and water, thereby improving the reliability and stability of the connection between the mounting bracket 300 and the battery 100, and enhancing the reliability and stability of the battery 100 mounted on the vehicle 1000.

[0204] In some embodiments, at least a portion of the mounting portion 30 is located between the battery 100 and the vehicle body 200. Therefore, the location of at least a portion of the mounting portion 30 is concealed, making it less susceptible to damage from impacts or corrosion from mud and water, thereby improving the reliability and stability of the connection between the mounting bracket 300 and the vehicle body 200, and enhancing the reliability and stability of the battery 100 mounted on the vehicle 1000.

[0205] It is worth noting that the mounting part 30 is not limited in its position on the mounting frame 300. It can be specifically selected according to the structural characteristics of the mounting frame 300 and its matching position with the vehicle body 200. For example, when the mounting frame 300 is in the form of the side frame part 10 and the middle frame part 20 mentioned above, the mounting part 30 may include the first mounting part 31 and / or the second mounting part 32 mentioned above, but this application is not limited to this.

[0206] In some embodiments, at least a portion of the mounting bracket 300 is located between the battery 100 and the underbody longitudinal beam 201 of the vehicle body 200, so that at least a portion of the mounting portion 30 can be connected to the underbody longitudinal beam 201.

[0207] In the above technical solution, the mounting bracket 300 and the longitudinal beam 201 of the vehicle bottom can be reliably connected, and it can be installed on a variety of vehicle models, making it widely applicable.

[0208] Furthermore, this application also proposes a vehicle 1000, including a vehicle body 200 and the aforementioned mounting bracket 300, with the mounting bracket 300 connected to the vehicle body 200. This reduces the design and manufacturing complexity of the battery 100 and the vehicle body 200, and facilitates meeting the requirements for mounting the battery 100 onto the vehicle 1000.

[0209] In some embodiments, such as Figures 1-3 As shown, the vehicle body 200 includes a bottom longitudinal beam 201, and the vehicle 1000 includes a plurality of mounting brackets 300 arranged sequentially along the length of the bottom longitudinal beam 201.

[0210] Therefore, the size of each mounting bracket 300 can be relatively small, which can improve the shape accuracy of each mounting bracket 300, facilitate the connection between each mounting bracket 300 and the vehicle body 200, and improve the structural strength of each mounting bracket 300, thereby improving the stability of the battery 100 mounted on the vehicle 1000.

[0211] It is worth noting that when there are multiple mounting brackets 300, multiple mounting brackets 300 can be used to install one battery 100 together, or each mounting bracket 300 can install one battery 100 separately. The setting can be determined according to the actual situation of the battery 100, and there is no restriction here.

[0212] In some embodiments, the vehicle 1000 further includes a battery 100, which is mounted to the vehicle body 200 via a mounting bracket 300. The structural form of the battery 100 is not limited; for example, in… Figures 1-3 In the example shown, the vehicle body 200 includes a chassis longitudinal beam 201, the battery 100 has a recess 101 with an open top that houses the chassis longitudinal beam 201, the battery 100 includes battery cells located below and on both sides of the recess 101, and a mounting bracket 300 is sandwiched between the recess 101 and the chassis longitudinal beam 201.

[0213] In the above technical solution, the battery 100 can make full use of the space to set more battery cells, thereby increasing the battery capacity of the battery 100. Moreover, the battery 100 and the vehicle under longitudinal beam 201 can protect the mounting bracket 300, making the mounting bracket 300 hidden and not easily damaged by bumps or corrosion by mud and water, thereby improving the reliability and stability of the battery 100 mounted on the vehicle 1000.

[0214] Of course, this application is not limited to this. In other embodiments of this application, the battery 100 may be configured in other shapes, such as being located only on one side or the bottom side of the longitudinal beam 201 of the vehicle floor, etc. There are no restrictions here.

[0215] Below, refer to Figures 1-4 as well as Figures 8-10 This application describes a mounting bracket 300 according to a specific embodiment.

[0216] The mounting bracket 300 is used to mount the battery 100 to the vehicle body 200. The mounting bracket 300 includes a side bracket portion 10 and a center bracket portion 20. The two side bracket portions 10 are located on both sides of the width of the vehicle under longitudinal beam 201, and the two ends of the center bracket portion 20 are respectively connected to the lower ends of the two side bracket portions 10, so as to form a clearance space 21 between the two side bracket portions 10 and the center bracket portion 20 for avoiding the vehicle under longitudinal beam 201 and with an open top.

[0217] The mounting bracket 300 has a mounting portion 30 for connection to the vehicle body 200. The mounting portion 30 includes a first mounting portion 31 located on the side wall of the side frame portion 10 facing the longitudinal beam 201 of the vehicle floor, and a second mounting portion 32 located on the bottom wall of the center frame portion 20 facing the longitudinal beam 201 of the vehicle floor. For example, the mounting portion 30 can be locked by cooperating with a locking mechanism on the vehicle body 200, or it can be connected to the vehicle body 200 by fasteners, etc.

[0218] The side of the side bracket 10 facing away from the side wall of the vehicle undercarriage longitudinal beam 201 has a connecting part for connecting to the battery 100. For example, the battery 100 has a recess 101 that avoids the vehicle undercarriage longitudinal beam 201, and the side wall of the recess 101 has a mounting pin. During installation, the mounting bracket 300 is first installed onto the vehicle undercarriage longitudinal beam 201, and then the battery 100 is lifted from bottom to top, so that the mounting bracket 300 extends into the recess 101 of the battery 100. The mounting pin can cooperate with the connecting part to realize the mounting of the battery 100 onto the mounting bracket 300.

[0219] Therefore, the mounting bracket 300 only occupies the space within the recess 101 of the battery 100, saving the volume and weight of the mounting bracket 300, improving the overall energy density. Furthermore, since both the mounting part 30 and the connecting part are located between the recess 101 of the battery 100 and the longitudinal beam 201 of the vehicle floor, the mounting part 30 and the connecting part have high precision, effectively improving installation efficiency, battery swapping efficiency, and battery swapping success rate.

[0220] Furthermore, the connecting part can be located between the recess 101 and the side wall of the vehicle bottom longitudinal beam 201, and the mounting part 30 can be located between the recess 101 and the vehicle bottom longitudinal beam 201, so that the battery 100 can block mud, splash water, etc., and prevent mud and splash water from contacting the mounting part 30 and the connecting part, thereby improving the reliability and service life of the mounting part 30 and the connecting part.

[0221] Furthermore, since the connecting part can be located between the recess 101 and the side wall of the longitudinal beam 201 of the vehicle bottom, the deformation of the mounting bracket 300 at this location is small, the spacing between adjacent connecting parts is small, the spacing between adjacent sub-connecting parts 51 in the connecting part is small, and the positional accuracy of the connecting part is high, thereby improving the battery swapping accuracy and battery swapping efficiency.

[0222] The mid-frame 20 has a docking part 60, the vehicle body has a first docking structure, and the battery 100 has a second docking structure. The docking part 60 docks with the first docking structure on one hand and with the second docking structure on the other hand, thereby realizing the current conduction and liquid circuit conduction between the battery 100 and the vehicle 1000, and the battery 100 can supply power to the vehicle 1000.

[0223] The middle part has an upper protrusion 22 that extends into the space between the two longitudinal beams 202 of the vehicle bottom longitudinal beam 201. The docking part 60 is provided on the upper protrusion 22, so that the docking part 60 can be located between the two longitudinal beams 202 of the vehicle bottom longitudinal beam 201. This position is relatively concealed, and the battery 100 and the vehicle bottom longitudinal beam 201 can block the erosion of mud and splash water, thereby reducing the risk of electrical failure and improving the reliability of water and electricity connection.

[0224] The docking part 60 is located on the bottom wall of the upper protrusion 22 with the docking surface facing down. When the battery 100 is lifted upward, docking can be completed smoothly, thereby improving the assembly efficiency of the battery 100.

[0225] Optionally, at least a portion of the side frame portion 10 and at least a portion of the center frame portion 20 are integrally formed, which makes the mounting bracket 300 structurally strong and can improve the stability and reliability of the battery 100 mounted on the vehicle 1000.

[0226] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0227] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
