Mounting frame and vehicle Technical Field

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

[0002] New energy vehicles have experienced rapid growth in recent years. Batteries, as the power source, play an irreplaceable and crucial role in electric vehicles. Previously, batteries could be mounted under the vehicle using a frame. However, due to the varying vehicle models, this required developing specialized frames for each model, resulting in high costs.

[0003] Summary of the Invention

[0004] The embodiments of the present application provide a mounting bracket and a vehicle, wherein the mounting bracket has good universal compatibility.

[0005] In a first aspect, an embodiment of the present application provides a mounting bracket for mounting a battery to a vehicle body. The mounting bracket is suitable for spanning the longitudinal beam of the vehicle body, and a avoidance cavity for avoiding the longitudinal beam is formed on the mounting bracket. The mounting bracket is configured so that the size of the avoidance cavity in the width direction of the longitudinal beam is adjustable.

[0006] In the above technical solution, by setting the mounting frame so that the size of the avoidance cavity in the width direction of the vehicle bottom longitudinal beam is adjustable, it can adapt to the avoidance requirements of vehicle bottom longitudinal beams of different widths, thereby improving the adaptability of the mounting frame to different vehicle models and increasing the scope of application of the mounting frame.

[0007] In some embodiments, the mounting frame includes two first frames, at least a portion of which is adapted to be higher than the lower end of the vehicle bottom longitudinal beam and located on the side of the vehicle bottom longitudinal beam, an avoidance cavity is formed between the two first frames, and the two first frames can move relative to each other along the width direction of the vehicle bottom longitudinal beam.

[0008] In the above technical solution, the size of the avoidance cavity formed between the two first frames in the width direction of the vehicle bottom longitudinal beam can be adjusted through the relative movement of the two first frames, so that the size of the avoidance cavity in the width direction of the vehicle bottom longitudinal beam can be simply and effectively adjusted, simplifying the structure of the mounting frame and reducing the difficulty of size adjustment.

[0009] In some embodiments, the two first frames are directly slidably matched so that the two first frames can move relative to each other along the width direction of the bottom longitudinal beam.

[0010] In the above technical solution, the structure of the mounting frame can be simplified, the parts of the mounting frame can be reduced, the assembly steps of the mounting frame can be simplified, and the assembly efficiency of the mounting frame can be improved.

[0011] In some embodiments, the first frame includes a sliding segment adapted to be located below the vehicle bottom longitudinal beam, and the two sliding segments of the first frame are slidably matched.

[0012] In the above technical solution, by arranging the sliding section below the vehicle bottom longitudinal beam, the vehicle bottom longitudinal beam can be avoided simply and effectively without the need for special processing of the vehicle bottom longitudinal beam.

[0013] In some embodiments, the two sliding sections are both in the shape of slats and are stacked, or the two sliding sections are slidingly matched through a sliding rail and sliding groove structure, or the two sliding sections are slidingly matched through a sleeve column structure.

[0014] In the above technical solution, the structure of the sliding section is simple, which is convenient for processing and assembly, and the two sliding sections in the shape of slats and stacked together occupy less space.

[0015] In some embodiments, at least one sliding segment has a limiting portion at one end close to the other first frame, and the limiting portion cooperates with the other sliding segment to limit the relative sliding direction of the two sliding segments and prevent the two sliding segments from separating.

[0016] In the above technical solution, by providing the limiting portion, the two sliding sections can be prevented from separating and disengaging, thereby improving the structural reliability of the mounting frame, saving parts, and facilitating assembly.

[0017] In some embodiments, each first frame includes a plurality of sliding segments, and the plurality of sliding segments are adapted to be spaced apart along a length direction of the vehicle bottom longitudinal beam.

[0018] In the above technical solution, the stability of the sliding fit of the two first frames can be improved, and the interval space between the sliding segments can be used to avoid part of the battery, so that part of the battery can extend above the sliding segment, thereby improving space utilization.

[0019] In some embodiments, the mounting frame further includes a second frame, and the two first frames are respectively slidably matched with the second frame, so that the two first frames can move relative to each other along the width direction of the vehicle bottom longitudinal beam.

[0020] In the above technical solution, by providing the second frame, each first frame is slidably matched with the second frame, which is conducive to adapting to the vehicle bottom longitudinal beam with a larger width.

[0021] In some embodiments, the mounting bracket further includes an adjusting mechanism, the two first brackets are connected via the adjusting mechanism, and the adjusting mechanism is adjustable along the width direction of the vehicle bottom longitudinal beam.

[0022] In the above technical solution, by providing an adjustment mechanism with adjustable size along the width direction of the vehicle bottom longitudinal beam to connect the two first frames, the relative movement of the two first frames along the width direction of the vehicle bottom longitudinal beam can be achieved by changing the size of the adjustment mechanism, which is conducive to simplifying the design and processing of the first frames.

[0023] In some embodiments, the mounting bracket further includes a locking assembly capable of switching between a locked state and an unlocked state, and the locking assembly is used to lock the relative positions of the two first brackets in the locked state.

[0024] In the above technical solution, the relative positions of the two first frames are locked by the locking assembly, which facilitates the assembly of the mounting frame to the vehicle body.

[0025] In some embodiments, each first rack has a mounting portion, and the mounting portion is used to connect the mounting rack to the vehicle body.

[0026] In the above technical solution, by arranging the mounting portion on the first frame, since the two first frames can move relative to each other along the width direction of the vehicle bottom longitudinal beam, the mounting portion can be adapted to be connected to the vehicle bodies of different models, thereby increasing the applicability of the mounting frame.

[0027] In some embodiments, the mounting portion includes a first mounting portion adapted to be located on a side of the bottom rail.

[0028] In the above technical solution, since the first mounting portion is located on the side of the vehicle bottom longitudinal beam, there is sufficient space there, which facilitates the connection between the first mounting portion and the vehicle body and facilitates the flexible design of the first mounting portion.

[0029] In some embodiments, the first mounting portion is adapted to be connected to the side wall of the bottom rail via a first fastener extending in the transverse direction.

[0030] The above technical solution simplifies the connection between the first mounting portion and the vehicle body and improves the reliability of the connection. It also simplifies the structure and processing of the mounting frame and the vehicle bottom rail and improves the compactness of the fit between the side frame portion and the vehicle bottom rail.

[0031] In some embodiments, a plurality of first mounting portions are provided on the first frame, and the plurality of first mounting portions are adapted to be spaced apart along the length direction of the vehicle bottom longitudinal beam.

[0032] In the above technical solution, since the multiple first mounting portions are arranged at intervals along the length direction of the vehicle bottom longitudinal beam, the lateral space of the vehicle bottom longitudinal beam can be fully utilized, and a larger number of first mounting portions can be arranged to improve the connection reliability between the mounting frame and the vehicle body. In addition, the multiple first mounting portions are less likely to interfere with the vehicle bottom longitudinal beam when connected, which is conducive to the connection operation.

[0033] In some embodiments, the mounting portion includes a second mounting portion adapted to be disposed below the bottom rail.

[0034] In the above technical solution, since the second mounting portion is located below the vehicle bottom longitudinal beam, the scope of application can be improved and installation can be achieved for various vehicle models.

[0035] In some embodiments, the second mounting portion is adapted to be connected to the bottom wall of the bottom rail via a second fastener extending in the vertical direction.

[0036] In the above technical solution, the connection between the second mounting portion and the vehicle bottom longitudinal beam can be simplified, and the reliability of the connection between the second mounting portion and the vehicle bottom longitudinal beam can be improved. In addition, the structure and processing of the mounting frame and the vehicle bottom longitudinal beam can be simplified, and the compactness of the mounting frame and the vehicle bottom longitudinal beam can be improved.

[0037] In some embodiments, a plurality of second mounting portions are provided on the first frame, and the plurality of second mounting portions are adapted to be spaced apart along the length direction of the vehicle bottom longitudinal beam.

[0038] In the above technical solution, since the multiple second mounting portions are arranged at intervals along the length direction of the vehicle bottom longitudinal beam, the space below the vehicle bottom longitudinal beam can be fully utilized, and a larger number of second mounting portions can be arranged, thereby improving the connection reliability between the mounting frame and the vehicle body. In addition, the multiple second mounting portions are less likely to interfere with the vehicle bottom longitudinal beam when connected, which is conducive to the connection operation.

[0039] In some embodiments, at least a portion of the mounting portion is adapted to be located between the battery and the vehicle body.

[0040] In the above technical solution, since at least part of the mounting portion is hidden, it is not easily damaged by bumps or corroded by mud and water, thereby improving the reliability and stability of the connection between the mounting frame and the vehicle body, and improving the reliability and stability of the battery mounted on the vehicle.

[0041] In some embodiments, each first rack has a connecting portion, and the connecting portion is used to connect the mounting rack to the battery.

[0042] In the above technical solution, by providing a connecting portion to connect the battery, the stability and reliability of the cooperation between the battery and the mounting bracket can be improved, thereby improving the stability of mounting the battery on the vehicle.

[0043] In some embodiments, the mounting frame further includes a third frame, the first frame cooperates with the third frame to be movable relative to the third frame along the width direction of the vehicle bottom longitudinal beam, and the third frame has a connecting portion for connecting the mounting frame to the battery.

[0044] In the above technical solution, the first frame can be adjusted to adapt to different widths of the vehicle bottom longitudinal beams, and by arranging the connecting part on the third frame, it can always be connected to batteries of the same specifications. In this way, the specifications of the batteries do not need to be changed according to the different widths of the vehicle bottom longitudinal beams, making the batteries more compatible.

[0045] In some embodiments, the third frame includes a side frame portion located on a side of each first frame away from the bottom longitudinal beam, and the connecting portion is provided on the side frame portion.

[0046] In the above technical solution, the movement of the first frame will not interfere with the side frame part, and thus will not affect the connecting part, thereby simplifying the structure of the mounting frame.

[0047] In some embodiments, at least a portion of the connection portion is adapted to be located between the battery and the vehicle body.

[0048] In the above technical solution, at least part of the connection part is hidden and not easily damaged by bumps or eroded by mud and water, thereby improving the reliability and stability of the connection between the mounting frame and the battery, and improving the reliability and stability of the battery mounted on the vehicle.

[0049] In some embodiments, the connection portion includes a first connection portion adapted to be located between the battery and a side wall of the bottom rail.

[0050] In the above technical solution, the first connecting part can be better hidden, thereby protecting the battery and the vehicle body, reducing the probability of the first connecting part being eroded by mud and water or damaged by collisions and bumps by foreign objects, thereby improving the connection reliability between the battery and the mounting bracket, and facilitating the removal and replacement of the battery.

[0051] In some embodiments, the first connection portion includes a plurality of sub-connection portions, and the plurality of sub-connection portions are adapted to be spaced apart along a length direction of the bottom longitudinal beam.

[0052] In the above technical solution, since multiple sub-connections are arranged at intervals along the length direction of the vehicle bottom longitudinal beam, the space can be fully utilized, and a larger number of sub-connections can be arranged to improve the connection reliability between the mounting frame and the battery. In addition, the multiple sub-connections are less likely to interfere with each other when connected to or disconnected from the battery, which is beneficial to the battery removal and replacement operation.

[0053] In some embodiments, the mounting bracket includes a connecting lock, the connecting lock constituting the connecting portion, the connecting lock having a locking state for locking the battery and an unlocking state for releasing the battery.

[0054] In the above technical solution, a detachable connection between the connecting portion and the battery can be achieved, thereby enabling the battery to be removed and replaced.

[0055] In some embodiments, the third frame has a docking portion for docking with a fluid path and / or an electrical path on the battery.

[0056] In the above technical solution, by providing a docking portion on the mounting frame, the mounting frame's structural design can meet the docking requirements between the battery and the vehicle's electrical and / or fluid circuits, thereby simplifying the structural design of the vehicle body and battery. Furthermore, since the docking portion is located on a third frame that does not require adjustment or movement, the docking portion's installation stability is improved, thereby facilitating greater stability and reliability in the docking between the docking portion and the battery.

[0057] In some embodiments, the third frame includes a side frame portion located on a side of each first frame away from the vehicle bottom longitudinal beam, and the third frame also includes a middle frame portion connecting the side frame portions on both sides, the middle frame portion includes an upper protrusion suitable for extending into between the two side longitudinal beams of the vehicle bottom longitudinal beam, and the docking portion is provided on the bottom wall of the upper protrusion.

[0058] In the above technical solution, because the docking portion is located on the center frame, which connects the side frames on both sides, the center frame is more stable, which can improve the stability of the docking portion, and thus improve the stability and reliability of the docking portion and the battery. Moreover, because the docking portion is located between the two side rails of the vehicle bottom longitudinal beam, the docking portion is protected by the vehicle bottom longitudinal beam, reducing the probability of damage to the docking portion from bumps and collisions, improving the problem of corrosion failure caused by mud and water, and improving the reliability and stability of the docking. Moreover, the docking portion does not need to occupy space outside the vehicle bottom longitudinal beam, which helps save space and increase battery capacity.

[0059] In some embodiments, an avoidance opening is formed on the mounting frame, and the avoidance opening is suitable for being arranged corresponding to the space between the longitudinal beams on both sides of the vehicle bottom longitudinal beam.

[0060] In the above technical solution, part of the battery can be extended into between the longitudinal beams on both sides of the vehicle bottom longitudinal beam through the avoidance opening, so that the battery can be arranged in the vehicle bottom space in full utilization and the battery capacity can be increased.

[0061] In a second aspect, an embodiment of the present application provides a vehicle, comprising a vehicle body and the above-mentioned mounting frame, wherein the mounting frame is connected to the vehicle body.

[0062] In some embodiments, the vehicle body includes a bottom longitudinal beam, and the vehicle includes a plurality of mounting brackets sequentially arranged along a length direction of the bottom longitudinal beam.

[0063] In the above technical solution, the size of each mounting bracket can be relatively small, thereby improving the shape accuracy of each mounting bracket, facilitating the connection between each mounting bracket and the vehicle body, and also facilitating improving the structural strength of each mounting bracket, thereby improving the stability of the battery mounted on the vehicle.

[0064] In some embodiments, the vehicle further comprises a battery, and the battery is mounted to the vehicle body via a mounting bracket.

[0065] In some embodiments, the vehicle body includes a bottom longitudinal beam, the battery has a recess with an open top that receives the bottom longitudinal beam, the battery includes battery cells disposed below and on both sides of the recess, and the mounting frame is clamped between the recess and the bottom longitudinal beam.

[0066] In the above technical solution, the battery can make full use of the space to set up more battery cells, thereby increasing the battery capacity. In addition, the battery and the vehicle bottom longitudinal beam can be used to protect the mounting frame, so that the position of the mounting frame is hidden and not easily damaged by bumps or erosion by mud and water, thereby improving the reliability and stability of the battery installed in the vehicle.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0081] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0082] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0083] In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to direct connection or indirect connection through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0084] In this application, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0085] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0086] The term "plurality" used in this application refers to two or more (including two).

[0087] In this application, battery cells 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 do not limit this. Battery cells may be cylindrical, flat, rectangular, or other shapes, etc., and the embodiments of this application do not limit this. Battery cells are generally divided into three types based on the packaging method: cylindrical battery cells, prismatic battery cells, and soft-pack battery cells, and the embodiments of this application do not limit this.

[0088] The battery referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. The battery in the embodiments of this application includes a housing for enclosing one or more battery cells or multiple battery modules. A battery module is composed of multiple battery cells. The housing is used to prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0089] In a battery, multiple battery cells can be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to multiple battery cells being connected both in series and in parallel. Multiple battery cells can be directly connected in series, in parallel, or in a hybrid configuration, and the entire structure of the multiple battery cells is then housed within a housing. Of course, a battery can also be constructed by first connecting multiple battery cells in series, in parallel, or in a hybrid configuration to form a battery module. The multiple battery modules are then connected in series, in parallel, or in a hybrid configuration to form a single structure, which is then housed within a housing. Furthermore, the battery may include other structures, such as a busbar assembly for electrically connecting multiple battery cells.

[0090] New energy vehicles have experienced rapid development in recent years. Batteries, as the power source, play an irreplaceable and important role in electric vehicles. The inventors discovered that while batteries in related technologies can be mounted on the underbody of a vehicle via a frame, this requires developing different frames for each vehicle model, resulting in high costs.

[0091] Based on the above considerations, the inventors, after in-depth research, have designed a mounting bracket for mounting a battery to a vehicle body. The bracket spans the vehicle's floor rails and is formed with a clearance cavity for clearing the floor rails. The bracket is configured so that the clearance cavity is adjustable in the width direction of the floor rails. By configuring the bracket so that the clearance cavity is adjustable in the width direction of the floor rails, the bracket can accommodate the clearance requirements of floor rails of varying widths, thereby improving the bracket's adaptability to different vehicle models and broadening its applicability.

[0092] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The battery 100 can be used to power the vehicle 1000. For example, the battery 100 can serve as an 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 power the motor, for example, for the starting, navigation and driving power requirements of the vehicle 1000. In some embodiments of the present application, the battery 100 can not only serve as the operating power source of the vehicle 1000, but also as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0093] Hereinafter, with reference to the accompanying drawings, a mounting bracket 300 according to an embodiment of the present application will be described.

[0094] As shown in Figures 1 to 6, the mounting bracket 300 is used to install the battery 100 on the vehicle body 200. The mounting bracket 300 spans the vehicle bottom longitudinal beam 201 of the vehicle body 200, and an avoidance cavity 10 is formed on the mounting bracket 300 for avoiding the vehicle bottom longitudinal beam 201. The mounting bracket 300 is configured so that the size of the avoidance cavity 10 in the width direction of the vehicle bottom longitudinal beam 201 is adjustable.

[0095] It is worth noting that the connection method between the mounting bracket 300 and the vehicle body 200 is not limited, and the connection relationship between the mounting bracket 300 and the battery 100 is not limited, as long as the battery 100 can be mounted on the vehicle body 200 via the mounting bracket 300. For example, in some embodiments, the mounting bracket 300 and the battery 100 can be directly or indirectly connected. For example, in other embodiments, the mounting bracket 300 and the battery 100 may not have a connection relationship. For example, the mounting bracket 300 may only support and limit the battery 100 without being connected to the battery 100.

[0096] It should be noted that the length direction of the vehicle bottom longitudinal beam 201 described herein (e.g., the first direction X shown in Figures 1-3 ) corresponds to the front-to-rear direction of the vehicle body 200, the width direction of the vehicle bottom longitudinal beam 201 (e.g., the second direction Y shown in Figures 2-3 ) corresponds to the left-right direction of the vehicle body 200, and the height direction of the vehicle bottom longitudinal beam 201 (e.g., the third direction Z shown in Figures 2-3 ) corresponds to the up-down direction of the vehicle body 200. The vehicle bottom longitudinal beam 201 described herein may also be referred to as an automobile beam.

[0097] The phrase "mounting bracket 300 spans the bottom longitudinal beam 201 of the vehicle body 200" means that the mounting bracket 300 extends from the left side of the bottom longitudinal beam 201 to the right side of the bottom longitudinal beam 201, thereby fully utilizing the space under the vehicle. The mounting bracket 300 includes a clearance cavity 10 for clearing the bottom longitudinal beam 201, thereby preventing interference between the mounting bracket 300 and the bottom longitudinal beam 201. This allows for flexible design of the relative position of the mounting bracket 300 and the bottom longitudinal beam 201, allowing the mounting bracket 300 to be flexibly configured in a variety of shapes.

[0098] In the above technical solution, the mounting frame 300 is configured such that the size of the avoidance cavity 10 in the width direction of the vehicle bottom longitudinal beam 201 is adjustable, that is, the left and right widths of the avoidance cavity 10 are adjustable, thereby being able to adapt to the avoidance requirements of vehicle bottom longitudinal beams 201 of different left and right widths, thereby improving the adaptability of the mounting frame 300 to different vehicle models and increasing the scope of application of the mounting frame 300.

[0099] It should be noted that the structure of the avoidance cavity 10 is not limited, for example, it can be open at the top or open at the bottom, etc.

[0100] In some embodiments, as shown in Figures 5-7, the mounting frame 300 includes two first frames 20, at least a portion of the first frames 20 is higher than the lower end of the vehicle bottom longitudinal beam 201 and is located on the side of the vehicle bottom longitudinal beam 201, and the avoidance cavity 10 is formed between the two first frames 20. The two first frames 20 can move relative to each other along the width direction of the vehicle bottom longitudinal beam 201.

[0101] It should be noted that the "lateral side of the vehicle bottom longitudinal beam 201" herein refers to the left or right side of the vehicle bottom longitudinal beam 201 in terms of horizontal height. In the above technical solution, the first frame 20 can be arranged in the space on both sides of the vehicle bottom longitudinal beam 201, thereby improving space utilization. In the above embodiment, only one of the first frames 20 can be movable along the width of the vehicle bottom longitudinal beam 201, or both first frames 20 can be movable along the width of the vehicle bottom longitudinal beam 201.

[0102] In the above technical solution, the relative movement of the two first frames 20 can make the size of the avoidance cavity 10 formed between the two first frames 20 adjustable in the width direction of the vehicle bottom longitudinal beam 201, thereby making it possible to simply and effectively adjust the size of the avoidance cavity 10 in the width direction of the vehicle bottom longitudinal beam 201.

[0103] Of course, the present application is not limited to this. In other embodiments of the present application, the size adjustment of the avoidance cavity 10 can also be achieved by other means. For example, the mounting frame 300 may include an expandable gasket. By regulating the expansion degree of the gasket, the size adjustment of the avoidance cavity 10 can be achieved, thereby simplifying the structure of the mounting frame 300 and reducing the difficulty of size adjustment.

[0104] In some embodiments, as shown in Figures 5-7 , the two first frames 20 are directly slidably engaged with each other, allowing relative movement along the width of the vehicle bottom longitudinal beam 201. This simplifies the structure of the mounting frame 300, reduces the number of components of the mounting frame 300, simplifies the assembly steps of the mounting frame 300, and improves the assembly efficiency of the mounting frame 300.

[0105] In some embodiments, as shown in Figures 4-7 , the first frame 20 includes a sliding section 21 located below the vehicle bottom longitudinal beam 201. The sliding sections 21 of the two first frames 20 are slidably engaged. Thus, by positioning the sliding section 21 below the vehicle bottom longitudinal beam 201, the vehicle bottom longitudinal beam 201 can be avoided simply and effectively without requiring special processing of the vehicle bottom longitudinal beam 201.

[0106] It is worth noting that the matching manner of the sliding sections 21 of the two first frames 20 is not limited.

[0107] For example, in some embodiments, as shown in FIG. 4 to FIG. 7 , the two sliding segments 21 are both in the shape of strips and are stacked.

[0108] In the above technical solution, by configuring the sliding segments 21 in a strip shape, the structure of the sliding segments 21 is simplified, making them easier to process and assemble. Furthermore, because the two sliding segments 21 are stacked, i.e., their thicknesses are aligned in the same direction, for example, vertically, the two sliding segments 21 occupy less space when combined, thereby improving the compactness of the mounting bracket 300, the battery 100, and the vehicle body 200.

[0109] For example, in some other embodiments of the present application, the two sliding sections 21 are slidably matched through a sliding rail and groove structure, that is, the two sliding sections 21 can also be one that defines a sliding rail and the other that defines a groove, and the sliding rail slides in the groove. For example, in some other embodiments of the present application, the two sliding sections 21 are slidably matched through a sleeve column structure, that is, the two sliding sections 21 can be one of a hollow guide column and the other a sliding column inserted into the guide column, etc., which will not be elaborated here.

[0110] In some embodiments, as shown in Figures 4 to 7, at least one sliding segment 21 has a limiting portion 22 at one end close to the other first frame 20, and the limiting portion 22 cooperates with the other sliding segment 21 to guide the relative sliding direction of the two sliding segments 21 and prevent the two sliding segments 21 from separating.

[0111] In the above embodiment, the limiting portion 22 on one sliding segment 21 cooperates with the other sliding segment 21 to limit the relative movement of the two sliding segments 21 in the width direction of the vehicle bottom longitudinal beam 201, and can prevent the two sliding segments 21 from separating along the length direction and height direction of the vehicle bottom longitudinal beam 201. It can also be used to limit the extreme position of the relative movement of the two sliding segments 21 along the width direction of the vehicle bottom longitudinal beam 201 to prevent the two sliding segments 21 from separating along the width direction of the vehicle bottom longitudinal beam 201.

[0112] In the above technical solution, by providing the limiting portion 22, the two sliding sections 21 can be prevented from separating and disengaging, thereby improving the structural reliability of the mounting frame 300, saving parts, and facilitating assembly.

[0113] Among them, the structure of the limiting part 22 is not limited. For example, the limiting part 22 can be a flange buckle structure. For example, the width of the distal end of the sliding section 21 stacked below extends out from both sides of the lower flange and is buckled upward to the top of the sliding section 21 above. At the same time, the width of the distal end of the sliding section 21 stacked above extends out from both sides of the upper flange and is buckled downward to the bottom of the sliding section 21 below. Therefore, the limiting is reliable, the structure is simple, and it is easy to assemble.

[0114] For another example, the limiting portion 22 can also be in the form of a pin, and a sliding groove extending along the width direction of the vehicle bottom longitudinal beam 201 is formed on the other sliding segment 21. The pin slides in the sliding groove, and a limiting structure is provided on one end of the pin passing through the other sliding segment 21 to prevent the two sliding segments 21 from separating along the length and height directions of the vehicle bottom longitudinal beam 201. It can also be used to limit the extreme position of the relative movement of the two sliding segments 21 along the width direction of the vehicle bottom longitudinal beam 201 to prevent the two sliding segments 21 from separating along the width direction of the vehicle bottom longitudinal beam 201.

[0115] Of course, the present application is not limited to this. For example, in other embodiments of the present application, an open ring or the like can be provided instead of the limiting portion 22. That is, after the two sliding segments 21 are fitted into place, the opening of the ring is opened and sleeved outside the two sliding segments 21, and then the opening of the ring is closed, thereby limiting the separation of the two sliding segments 21 in directions other than the sliding direction. This will not be elaborated here.

[0116] In some embodiments, each first frame 20 includes a plurality of sliding segments 21 spaced apart along the length direction of the bottom longitudinal beam 201 .

[0117] In the above technical solution, the two first frames 20 can achieve relative sliding through the cooperation of multiple groups of sliding segments 21, thereby improving the stability of the sliding cooperation of the two first frames 20 and improving the structural reliability of the mounting frame 300. In addition, the interval space between two adjacent sliding segments 21 along the length direction of the vehicle bottom longitudinal beam 201 can be utilized to avoid part of the battery 100, so that part of the battery 100 can extend above the sliding segment 21, thereby improving space utilization.

[0118] It should be noted that each first frame 20 can be a separate piece that is assembled and connected, or each first frame 20 can also be an integrally formed piece, which is not limited here.

[0119] Of course, the present application is not limited thereto. The two first frames 20 may not be directly slidably engaged with each other. For example, in some other embodiments of the present application, as shown in FIG8 , the mounting frame 300 may further include a second frame 30, and the two first frames 20 may be slidably engaged with each other to enable the two first frames 20 to move relative to each other along the width direction of the vehicle bottom longitudinal beam 201. The above technical solution is advantageously adapted to vehicle bottom longitudinal beams 201 having a wider width.

[0120] It is worth noting that, in this embodiment, the sliding cooperation mode and the limiting mode of the second frame 30 and the first frame 20 can refer to the sliding cooperation mode and the limiting mode of the two first frames 20 in the above embodiment, and will not be repeated here.

[0121] Of course, the present application is not limited to this. For example, in other embodiments of the present application, as shown in FIG9 , the mounting bracket 300 may further include an adjustment mechanism 40, and the two first brackets 20 are connected via the adjustment mechanism 40. The adjustment mechanism 40 is adjustable along the width direction of the vehicle bottom longitudinal beam 201. The above technical solution facilitates the simplification of the design and processing of the first bracket 20.

[0122] It is worth noting that the specific structure of the adjustment mechanism 40 is not limited. For example, it can be a gear rack mechanism, a ball screw mechanism, or a worm gear mechanism, etc. In addition, the adjustment mechanism 40 can be manually adjusted or driven. When it is driven, an electric drive source, a hydraulic drive source, or a pneumatic drive source can be set to drive the adjustment mechanism 40, which will not be elaborated here.

[0123] In some embodiments, the mounting bracket 300 further includes a locking assembly capable of switching between a locked state and an unlocked state, and the locking assembly is used to lock the relative positions of the two first brackets 20 in the locked state.

[0124] In the above technical solution, the relative position of the two first frames 20 is locked by the locking assembly, which facilitates the assembly of the mounting frame 300 to the vehicle body 200. For example, the relative position of the two first frames 20 can be adjusted first, then locked, and then assembled to the vehicle body 200, making assembly easier.

[0125] The specific structure of the locking assembly is not limited, for example, it can be manually locked, or driven locked, for example, it can be pin locked, or lock plug locked, etc.

[0126] Of course, the present application is not limited thereto. For example, when the first frame 20 is provided with a mounting portion 50 described later, the locking assembly may be eliminated to simplify the structure.

[0127] In some embodiments, as shown in FIG. 5 to FIG. 7 , each first frame 20 has a mounting portion 50 , and the mounting portion 50 is used to connect the mounting frame 300 to the vehicle body 200 .

[0128] It is worth noting that the connection method between the mounting portion 50 and the vehicle body 200 is not limited. For example, in some embodiments, the mounting portion 50 itself can be connected to the vehicle body 200, such as the mounting portion 50 being a rivet screw or a buckle, etc. In other embodiments, the mounting portion 50 can be connected to the vehicle body 200 through a connector, such as a connection hole or a rivet nut, and can be connected to the vehicle body 200 through a connector such as a screw or bolt.

[0129] In the above technical solution, by providing the mounting portion 50 on the first frame 20, the two first frames 20 can move relative to each other along the width direction of the vehicle bottom longitudinal beam 201. This allows the mounting portion 50 to adapt to different vehicle bodies 200, thereby increasing the applicability of the mounting frame 300. Furthermore, since each first frame 20 has a mounting portion 50 for connecting to the vehicle body 200, connection can be made on both sides, thereby improving the installation stability and reliability of the mounting frame 300.

[0130] In some embodiments, as shown in FIG. 5 to FIG. 7 , the mounting portion 50 includes a first mounting portion 51 located on a side of the bottom longitudinal beam 201 .

[0131] In the above technical solution, since the first mounting portion 51 is located on the side of the vehicle bottom longitudinal beam 201, there is sufficient space here, which facilitates the connection between the first mounting portion 51 and the vehicle body 200 on the one hand, and facilitates the flexible design of the first mounting portion 51 on the other hand.

[0132] In addition, when the first mounting portions 51 are provided on the first brackets 20 on both sides, the connection reliability between the mounting brackets 300 and the vehicle body 200 can be improved, thereby improving the stability of mounting the battery 100 on the vehicle 1000 .

[0133] For example, in some embodiments, the first mounting portion 51 can be clamped between the battery 100 and the side wall of the vehicle bottom longitudinal beam 201, so that the first mounting portion 51 can 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 portion 51 and the vehicle body 200.

[0134] 4-5 , the first mounting portion 51 is connected to the side wall of the vehicle bottom longitudinal beam 201 via a first fastener extending in the transverse direction. The first fastener may be any type, such as a screw, bolt, rivet, or the like.

[0135] In the above technical solution, since the first mounting portion 51 is located on the side of the vehicle bottom longitudinal beam 201, the first mounting portion 51 is connected to the side wall of the vehicle bottom longitudinal beam 201 by using a first fastener extending in the transverse direction. This can utilize the characteristics of the relative positional relationship between the first mounting portion 51 and the vehicle bottom longitudinal beam 201 to simplify the connection between the first mounting portion 51 and the vehicle body 200 and improve the reliability of the connection between the first mounting portion 51 and the vehicle body 200.

[0136] Furthermore, this connection method only requires drilling holes or installing nuts on the sidewalls of the mounting portion 50 and the vehicle bottom longitudinal beam 201, eliminating the need for complex connectors or adjustments to the connection direction. This simplifies the structure and processing of the mounting portion 50 and the vehicle bottom longitudinal beam 201. Furthermore, it improves the compactness of the mounting portion 50 and the vehicle bottom longitudinal beam 201, saving space and facilitating the installation of batteries 100 with higher capacity.

[0137] In some embodiments, as shown in Figures 4 and 5 , the first frame 20 is provided with a plurality of first mounting portions 51 spaced apart along the length of the vehicle bottom longitudinal beam 201. In the above technical solution, since the plurality of first mounting portions 51 are spaced apart along the length of the vehicle bottom longitudinal beam 201, the lateral space of the vehicle bottom longitudinal beam 201 can be fully utilized, a larger number of first mounting portions 51 can be provided, and the connection reliability between the mounting frame 300 and the vehicle body 200 is improved. Furthermore, the plurality of first mounting portions 51 are less likely to interfere with the vehicle bottom longitudinal beam 201 when connected, facilitating the connection operation.

[0138] In some embodiments, as shown in FIG. 4-FIG . 5 , the mounting portion 50 includes a second mounting portion 52 disposed below the bottom longitudinal beam 201 .

[0139] In the above technical solution, since the second mounting portion 52 is located below the vehicle bottom longitudinal beam 201 , the scope of application can be improved, and installation can be achieved for various vehicle models.

[0140] In addition, when the second mounting portion 52 is provided on the first brackets 20 on both sides, the connection reliability between the mounting bracket 300 and the vehicle body 200 can be improved, thereby improving the stability of mounting the battery 100 on the vehicle 1000 .

[0141] For example, in some embodiments, the second mounting portion 52 can be clamped between the battery 100 and the bottom wall of the vehicle bottom longitudinal beam 201, so that the second mounting portion 52 can be easily hidden and protected by the battery 100 and the vehicle bottom longitudinal beam 201, thereby improving the connection reliability between the second mounting portion 52 and the vehicle body 200.

[0142] In addition, when the mounting portion 50 includes both the first mounting portion 51 and the second mounting portion 52 , the mounting bracket 300 can be connected to the vehicle body 200 from different positions, thereby improving the connection reliability between the mounting bracket 300 and the vehicle body 200 .

[0143] 4-5 , the second mounting portion 52 is connected to the bottom wall of the vehicle bottom longitudinal beam 201 via a second fastener extending vertically. The second fastener may be any type, such as a screw, bolt, rivet, or the like.

[0144] In the above technical solution, by using a second fastener extending vertically to connect the second mounting portion 52 to the bottom wall of the vehicle bottom longitudinal beam 201, the characteristics of the relative positional relationship between the second mounting portion 52 and the vehicle bottom longitudinal beam 201 can be utilized to simplify the connection between the second mounting portion 52 and the vehicle bottom longitudinal beam 201 and improve the connection reliability of the second mounting portion 52 and the vehicle bottom longitudinal beam 201.

[0145] Furthermore, this connection method requires only drilling holes or installing nuts on the bottom walls of the mounting bracket 300 and the vehicle bottom rail 201. It eliminates the need for complex connectors or adjustments to the connection orientation, simplifying the structure and processing of the mounting bracket 300 and the vehicle bottom rail 201. Furthermore, it improves the compactness of the mounting bracket 300 and the vehicle bottom rail 201, saving space and facilitating the installation of batteries 100 with higher capacity.

[0146] In some embodiments, the first frame 20 is provided with a plurality of second mounting portions 52 spaced apart along the length direction of the vehicle bottom longitudinal beam 201 .

[0147] In the above technical solution, since the plurality of second mounting portions 52 are arranged at intervals along the length direction of the vehicle bottom longitudinal beam 201, the space below the vehicle bottom longitudinal beam 201 can be fully utilized, and a larger number of second mounting portions 52 can be provided, thereby improving the connection reliability between the mounting frame 300 and the vehicle body 200. In addition, the plurality of second mounting portions 52 are less likely to interfere with each other when connected to the vehicle bottom longitudinal beam 201, which facilitates the connection operation.

[0148] In some embodiments, at least a portion of the mounting portion 50 is located between the battery 100 and the vehicle body 200. Thus, at least a portion of the mounting portion 50 is concealed and 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 300 and the vehicle body 200 and the reliability and stability of the battery 100 mounted on the vehicle 1000.

[0149] In some embodiments, as shown in FIG. 2 , FIG. 3 and FIG. 5 , each first rack 20 has a connecting portion 60 , and the connecting portion 60 is used to connect the mounting rack 300 to the battery 100 .

[0150] In the above technical solution, by providing the connection portion 60 to connect the battery 100, the stability and reliability of the fit 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. In addition, when both the mounting portion 50 and the connection portion 60 are provided on the first bracket 20, the structure and processing of the mounting bracket 300 can be simplified.

[0151] Furthermore, by providing the connection portion 60, the mounting frame 300 can be used to mount the battery 100, eliminating the need for the mounting frame 300 to be configured as a bracket to support the battery 100. Alternatively, the mounting frame 300 can be configured as a bracket to support the battery 100, thereby enabling flexible configuration of the mounting frame 300. It is understood that if the bracket is in the shape of a tray, supported at the bottom of the battery and surrounding the battery, the bracket occupies relatively more space.

[0152] The battery 100 and the connecting portion 60 may be directly or indirectly connected to achieve connection between the battery 100 and the mounting bracket 300. In some embodiments of the present application, the connecting portion 60 and the battery 100 may be detachably connected. In the above technical solution, since the connecting portion 60 and the battery 100 are detachably connected, the battery 100 can be removed and replaced. The structure of the connecting portion 60 is not limited, and for example, it can be a snap-fit ​​snap lock or lock pin, or a threaded bolt lock or nut, etc., and is not limited here.

[0153] It is worth noting that the connection portion 60 is not limited to the location on the first frame 20 and can be selected based on the structural characteristics of the first frame 20 and the matching position with the vehicle body 200. Of course, the present application is not limited thereto, and the connection portion 60 may also not be located on the first frame 20.

[0154] For example, in some other embodiments of the present application, as shown in Figure 10, the mounting frame 300 may also include a third frame 70, the first frame 20 cooperates with the third frame 70 to move relative to the third frame 70 along the width direction of the vehicle bottom longitudinal beam 201, and the connecting portion 60 for connecting the mounting frame 300 and the battery 100 may also be provided on the third frame 70.

[0155] In the above technical solution, the first frame 20 can be adjusted to adapt to different widths of the vehicle bottom longitudinal beam 201, and by arranging the connecting portion 60 on the third frame 70, it can always be connected to the battery 100 of the same specification. In this way, the specifications of the battery 100 do not need to be changed according to the different widths of the vehicle bottom longitudinal beam 201, so that the battery 100 can be standardized in design and has good compatibility.

[0156] In some embodiments, as shown in Figure 10 , the third frame 70 includes a side frame portion 71 located on the side of each first frame 20 away from the bottom rail 201, and the connecting portion 60 is disposed on the side frame portion 71. That is, along the width direction of the bottom rail 201, the side frame portion 71 is located on the side of the first frame 20 away from the bottom rail 201. In this technical solution, the movement of the first frame 20 does not interfere with the side frame portion 71, thereby not affecting the connecting portion 60, thereby simplifying the structure of the mounting frame 300.

[0157] In some embodiments, at least a portion of the connection portion 60 is located between the battery 100 and the vehicle body 200. Thus, at least a portion of the connection portion 60 is concealed and 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 300 and the battery 100 and the reliability and stability of the battery 100 when mounted on the vehicle 1000.

[0158] In some embodiments, as shown in FIG. 3 to FIG. 5 , the connection portion 60 includes a first connection portion 61 located between the battery 100 and a side wall of the bottom longitudinal beam 201 of the vehicle body 200 .

[0159] In the above technical solution, since the first connecting portion 61 is located between the battery 100 and the side wall of the bottom longitudinal beam 201 of the vehicle body 200, the first connecting portion 61 can be better hidden, thereby protecting the battery 100 and the vehicle body 200, reducing the probability of the first connecting portion 61 being eroded by mud and water or damaged by collisions and bumps by foreign objects, thereby improving the connection reliability between the battery 100 and the mounting bracket 300, and facilitating the removal and replacement of the battery 100.

[0160] In addition, since the first connecting portion 61 is located between the battery 100 and the side wall of the bottom longitudinal beam 201 of the vehicle body 200, the first connecting portion 61 is close to the bottom longitudinal beam 201, and the deformation of the mounting frame 300 at the position of the first connecting portion 61 is relatively small, which can improve the position accuracy of the first connecting portion 61. Moreover, when the first connecting portion 61 is provided on both sides of the bottom longitudinal beam 201, the relative distance between the first connecting portions 61 on both sides of the bottom longitudinal beam 201 is relatively close, and the relative position accuracy of the first connecting portions 61 on both sides is high, which makes it easy to achieve alignment connection between the battery 100 and the first connecting portion 61, thereby improving the assembly efficiency of the battery 100.

[0161] In the related art, some mounting brackets for mounting batteries on vehicles have battery-changing locks arranged around the batteries. The battery-changing locks are exposed to the outside. During the operation of the vehicle, mud, splashing water, etc. will have adverse effects on the battery-changing locks. After the vehicle has been running for a period of time, the battery-changing locks are often corroded and cannot be replaced. In addition, since the battery-changing locks are arranged around the battery, the span between the battery-changing locks is large, and the deformation of the mounting bracket at the battery-changing lock is relatively large, the matching accuracy of the battery-changing locks is low, which affects the battery-changing efficiency. In some embodiments of the present application, the above-mentioned technical problems can be effectively solved by arranging all the connecting parts 60 between the battery 100 and the side wall of the vehicle bottom longitudinal beam 201, that is, all the connecting parts 60 are the first connecting parts 61.

[0162] In some embodiments, as shown in FIG. 3 to FIG. 5 , the first connection portion 61 includes a plurality of sub-connection portions 611 spaced apart from each other along the length direction of the bottom longitudinal beam 201 .

[0163] In the above technical solution, when the first connection portion 61 is located between the battery 100 and the side wall of the bottom longitudinal beam 201 of the vehicle body 200, since the multiple sub-connection portions 611 are arranged at intervals along the length direction of the bottom longitudinal beam 201, the space can be fully utilized, and a larger number of sub-connection portions 611 can be arranged to improve the connection reliability between the mounting bracket 300 and the battery 100. In addition, the multiple sub-connection portions 611 are less likely to interfere with each other when connecting or disconnecting with the battery 100, which is beneficial to the removal and replacement operation of the battery 100.

[0164] In some embodiments, as shown in Figures 3-5, the mounting bracket 300 includes a connection lock 62, which constitutes the connecting portion 60. The connection lock 62 has a locked state for locking the battery 100 and an unlocked state for releasing the battery 100. Thus, a detachable connection between the connecting portion 60 and the battery 100 can be achieved, thereby enabling the battery 100 to be removed and replaced.

[0165] In the above technical solution, since the connection portion 60 is defined by the connection lock 62 , different forms of connection locks 62 can be selected or designed to meet the installation requirements of different batteries 100 .

[0166] It should be noted that the specific structure and form of the connecting lock 62 are not limited, and may be, for example, a snap lock or a bolt lock. For example, when the connecting lock 62 is a snap lock, as shown in FIG5 , the connecting lock 62 is housed within the first frame 20, which has a bottom-open hanging hole. The battery 100 may have a hanging pin adapted to extend upwardly into the hanging hole and lockably engage with a lock core within the connecting lock 62, thereby facilitating assembly of the battery 100 with the mounting bracket 300. For another example, when the connecting lock 62 is a bolt lock, the connecting lock 62 may be a bolt or nut extending axially vertically, adapted to engage with a nut or bolt on the battery 100, thereby facilitating assembly of the battery 100 with the mounting bracket 300. This will not be described in detail herein.

[0167] For example, the first frame 20 may include two sheet metal parts connected by welding, and a storage cavity is defined between the two sheet metal parts. The connecting lock 62 is arranged in the storage cavity. A fixing point and a hanging hole are formed on one of the sheet metal parts, and a mounting portion 50 is provided on the other sheet metal part. The connecting lock 62 can be fixed to the fixing point by fasteners such as bolts, and then the sheet metal part is welded to the other sheet metal part, and then the first frame 20 is installed to the vehicle body 200 through the mounting portion 50. As a result, the structure of the first frame 20 is simple, and the position of the connecting lock 62 is concealed, which can improve the reliability of the connecting lock 62 and the effectiveness of battery replacement.

[0168] In addition, a water-blocking component, such as a waterproof curtain, can be provided at the hanging hole position. When the padlock pin is inserted into the hanging hole, the waterproof curtain can be opened. When the padlock pin leaves the hanging hole, the waterproof curtain can be restored to the state of covering the hanging hole, thereby achieving a waterproof effect and further protecting the connecting lock 62.

[0169] In some embodiments, as shown in FIG. 10 , when the mounting bracket 300 includes the third bracket 70 described above, the third bracket 70 may have a docking portion 80 for docking with the fluid path and / or circuit on the battery 100 .

[0170] In the above technical solution, the mounting bracket 300 can interface with the electrical circuits and / or fluid circuits on the vehicle body 200, and a docking portion 80 is provided on the third bracket 70 for interfacing with the fluid circuits and / or electrical circuits on the battery 100, thereby enabling electrical conduction, fluid conduction, or both electrical conduction and fluid conduction between the vehicle body 200 and the battery 100. For example, when the docking portion 80 achieves electrical conduction, it can be used to transfer current between the vehicle 1000 and the battery 100, enabling the battery 100 to power the vehicle 1000 and control the battery 100 by the vehicle 1000. For example, when the docking portion 80 achieves fluid conduction, it can be used to transfer heat between the vehicle 1000's coolant system and the battery 100, thereby utilizing the coolant system to regulate the battery 100's temperature to improve its operational reliability and safety, or utilizing the coolant system to absorb 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 further described here.

[0171] Thus, by providing the docking portion 80 on the mounting frame 300, the structural design of the mounting frame 300 can meet the requirements for docking the circuit and / or fluid circuits of the battery 100 with the vehicle body 200, thereby simplifying the structural design of the vehicle body 200 and the battery 100. Furthermore, because the docking portion 80 is provided on the third frame 70, which does not require adjustment or movement, the stability of the docking portion 80 can be improved, which facilitates improving the stability and reliability of the docking between the docking portion 80 and the battery 100.

[0172] It should be noted that the location of the docking portion 80 is not limited and can be selected according to the shape of the third frame 70 .

[0173] In some embodiments, as shown in Figure 10, the third frame 70 may include a side frame portion 71 located on a side of each first frame 20 away from the vehicle bottom longitudinal beam 201, and the third frame 70 also includes a middle frame portion 72 connecting the side frame portions 71 on both sides, and the middle frame portion 72 includes an upper protrusion 721 extending between the two side longitudinal beams 202 of the vehicle bottom longitudinal beam 201, and the docking portion 80 is arranged on the bottom wall of the upper protrusion 721.

[0174] In the above technical solution, since the docking portion 80 is located on the center frame portion 72 and connects the side frames 71 on both sides, the center frame portion 72 is more stable, which can improve the stability of the docking portion 80 and facilitate the stability and reliability of the docking portion 80 and the battery 100. Moreover, since the docking portion 80 is located between the two side rails 202 of the vehicle bottom rail 201, the docking portion 80 is protected by the vehicle bottom rail 201, reducing the probability of damage to the docking portion 80 from bumps and collisions, improving the problem of corrosion failure of the docking portion 80 due to mud and water, improving the reliability and stability of the docking, and reducing the risk of electrical failure caused by erosion of the docking portion 80 due to mud and splashing water. Moreover, the docking portion 80 does not occupy space outside the vehicle bottom rail 201, which helps save space and increase the capacity of the battery 100. Moreover, the location of the docking portion 80 on the center frame portion 72 does not interfere with the mating of the mounting frame 300 with the vehicle bottom rail 201, facilitating the assembly of the mounting frame 300 to the vehicle body 200.

[0175] In some embodiments, the vehicle bottom longitudinal beam 201 may further include a plurality of cross beams 203 located between the longitudinal beams 202 on both sides, and the upper protrusion 721 may extend between adjacent cross beams 203 .

[0176] In some embodiments, the docking surface of the docking portion 80 can be positioned vertically downward. Thus, as the battery 100 is lifted upward, the docking portion 80 can be docked with the battery 100, thereby facilitating docking of the battery 100 with the docking portion 80. Furthermore, this docking arrangement saves space for the battery 100 to move.

[0177] In some embodiments, the docking surface of the docking portion 80 can be tilted downward. Thus, as the battery 100 is tilted upward, the docking portion 80 and the battery 100 can be docked together, thereby facilitating the docking of the battery 100 with the docking portion 80.

[0178] In some embodiments, the docking surface of the docking portion 80 can be horizontally arranged. Thus, as the battery 100 is first lifted upward and then moved horizontally, the docking portion 80 and the battery 100 can be docked together, thereby facilitating the docking of the battery 100 with the docking portion 80.

[0179] In some embodiments, as shown in Figures 3-5, an avoidance opening 11 is formed on the mounting frame 300, and the avoidance opening 11 is set corresponding to the space between the longitudinal beams 202 on both sides of the vehicle bottom longitudinal beam 201. In the above technical solution, a part of the battery 100 can be extended into between the longitudinal beams 202 on both sides of the vehicle bottom longitudinal beam 201 through the avoidance opening 11, so that the battery 100 can be fully utilized to set the battery 100 in the space under the vehicle, thereby increasing the capacity of the battery 100.

[0180] For example, when the first frame 20 includes a sliding section 21 , the avoidance opening 11 may be formed between two sliding sections 21 adjacently disposed along the length direction of the bottom longitudinal beam 201 , thereby simplifying the structure of the mounting frame 300 .

[0181] In addition, the present application also provides a vehicle 1000, comprising a vehicle body 200 and the aforementioned mounting bracket 300, wherein the mounting bracket 300 is connected to the vehicle body 200. This facilitates application to various vehicle models.

[0182] In some embodiments, as shown in FIG. 1 to FIG. 3 , the vehicle body 200 includes a bottom longitudinal beam 201 , and the vehicle 1000 includes a plurality of mounting brackets 300 sequentially arranged along the length direction of the bottom longitudinal beam 201 .

[0183] As a result, the size of each mounting bracket 300 can be relatively small, thereby improving the shape accuracy of each mounting bracket 300, facilitating the connection between each mounting bracket 300 and the vehicle body 200, and also facilitating improving the structural strength of each mounting bracket 300, thereby improving the stability of the battery 100 mounted on the vehicle 1000.

[0184] It is worth noting that when there are multiple mounting racks 300, multiple mounting racks 300 can be used to jointly install one battery 100, or each mounting rack 300 can be used to install one battery 100 respectively. It can be set according to the actual situation of the battery 100 and is not limited here.

[0185] In some embodiments, vehicle 1000 further includes a battery 100, which is mounted to vehicle body 200 via a mounting bracket 300. The structural form of battery 100 is not limited. For example, in the example shown in Figures 1-3, vehicle body 200 includes a bottom longitudinal beam 201. Battery 100 has a recess 101 with an open top that receives bottom longitudinal beam 201. Battery 100 includes battery cells disposed below and on both sides of recess 101. Mounting bracket 300 is sandwiched between recess 101 and bottom longitudinal beam 201.

[0186] In the above technical solution, the battery 100 can make full use of the space to set up more battery cells, thereby increasing the capacity of the battery 100. In addition, the battery 100 and the vehicle bottom longitudinal beam 201 can be used to protect the mounting frame 300, so that the position of the mounting frame 300 is concealed and not easily damaged by bumps or erosion by mud and water, thereby improving the reliability and stability of the battery 100 when mounted on the vehicle 1000.

[0187] Of course, the present application is not limited thereto. In other embodiments of the present application, the battery 100 may also be configured in other shapes, such as being located only on one side or the bottom side of the vehicle bottom longitudinal beam 201 , etc., which is not limited here.

[0188] 1 to 7 , a mounting bracket 300 according to a specific embodiment of the present application will be described below.

[0189] The mounting frame 300 is used to install the battery 100 on the vehicle body 200. The mounting frame 300 includes two first frames 20 arranged in sequence along the width direction of the vehicle bottom longitudinal beam 201. The two first frames 20 define an avoidance cavity 10 for avoiding the vehicle bottom longitudinal beam 201. The first frame 20 includes a first portion 2a located on the side of the vehicle bottom longitudinal beam 201 and a second portion 2b located below the vehicle bottom longitudinal beam 201.

[0190] The first portions 2a of the two first frames 20 are located on either side of the width of the vehicle bottom longitudinal beam 201. Mounting portions 50 are provided on the sidewalls of the first portions 2a facing the vehicle bottom longitudinal beam 201 for connection to the vehicle body 200. For example, the mounting portions 50 can be locked with a locking mechanism on the vehicle body 200, or connected to the vehicle body 200 via fasteners.

[0191] The second portions 2 b of the two second frames 30 are slidably engaged beneath the vehicle bottom longitudinal beam 201 . When used on different vehicle models, the distance between the mounting portions 50 on the two first frames 20 can be adjusted simply by pulling the two first frames 20 outward or pushing them inward relative to each other. This allows the mounting portions 50 to be locked and fixed to the vehicle bottom longitudinal beam 201 to accommodate vehicle bottom longitudinal beams 201 of varying widths.

[0192] A connection portion 60 is provided on the side of the first portion 2a facing away from the vehicle's bottom rail 201, for connecting to the battery 100. For example, the battery 100 has a recess 101 that avoids the vehicle's bottom rail 201, and a mounting pin is provided on the sidewall of the recess 101. During installation, the mounting bracket 300 is first mounted to the vehicle's bottom rail 201. The battery 100 is then lifted upward, allowing the mounting bracket 300 to extend into the recess 101 of the battery 100. The mounting pin engages with the connection portion 60 to secure the battery 100 to the mounting bracket 300.

[0193] As a result, 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 and improving the overall energy density. Moreover, since the mounting portion 50 and the connecting portion 60 are both located between the recess 101 of the battery 100 and the vehicle bottom longitudinal beam 201, the mounting portion 50 and the connecting portion 60 have high precision, which effectively improves the installation efficiency, battery replacement efficiency and battery replacement success rate.

[0194] Optionally, at least part of the first portion 2 a of the first frame 20 and at least part of the second frame 30 are integrally formed, so that the first frame 20 has good structural strength and can improve the stability and reliability of the battery 100 mounted on the vehicle 1000 .

[0195] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0196] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
