[0004] This application also proposes a battery pack comprising the aforementioned battery tray.

[0005] This application also proposes a vehicle that includes the aforementioned battery pack.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] In a first aspect, embodiments of this application provide a battery tray, including a tray body, a first limiting structure, a second limiting structure, and a limiting member. The first limiting structure is provided at both ends of the tray body along a first direction; the second limiting structure is provided at one end of the tray body along a second direction; the limiting member is detachably provided at the other end of the tray body along the second direction; wherein the tray body, the first limiting structure, the second limiting structure, and the limiting member together define an installation space for installing a battery, and along the thickness direction of the tray body, at least one of the first limiting structure, the second limiting structure, and the limiting member has a flange extending toward the installation space at its end away from the tray body, and the first direction, the second direction, and the thickness direction of the tray body are perpendicular to each other.

[0008] The battery tray provided in this application embodiment defines an installation space by defining a tray body, a first limiting structure, a second limiting structure, and a limiting member. Along the thickness direction of the tray body, at least one of the first limiting structure, the second limiting structure, and the limiting member has a flange extending towards the installation space at its end furthest from the tray body. This flange can limit the battery in the first direction, the second direction, and the thickness direction of the tray body, preventing displacement of the battery on the battery tray and avoiding abnormal noise caused by battery displacement. Simultaneously, the detachable connection between the limiting member and the tray body allows the limiting member to be installed on the tray body after the battery is inserted. This satisfies the requirement that the battery tray limits the battery in the first direction, the second direction, and the thickness direction of the tray body while facilitating the assembly of the battery and the battery tray, making the assembly of the battery and the battery tray relatively simple and convenient.

[0009] In one possible implementation of this application, the limiting member is provided with a wire harness hole, which penetrates the limiting member along the thickness direction.

[0010] In one possible implementation of this application, the limiting member and the tray body are connected by fasteners.

[0011] In one possible implementation of this application, the limiting member includes a first plate and a second plate, one end face of the first plate in the thickness direction is fitted and connected to the pallet body; the second plate is disposed on the side of the first plate near the installation space, and there is an included angle between the second plate, the first plate and the pallet body.

[0012] In one possible implementation of this application, the first limiting structure includes a first limiting plate, which is connected to the tray body, and a limiting protrusion is provided on the side of the first limiting plate near the installation space.

[0013] In one possible implementation of this application, there are multiple limiting protrusions, and the multiple limiting protrusions are spaced apart along the second direction.

[0014] In one possible implementation of this application, the second limiting structure includes a third plate connected to the pallet body, with an included angle between the third plate and the pallet body, and the flange connected to the end of the third plate away from the pallet body, the flange extending toward the direction close to the mounting space.

[0015] In one possible implementation of this application, the tray body, the first limiting structure, and the second limiting structure are integrally formed.

[0016] Secondly, this application provides a battery pack, which includes a battery tray as described above. The tray body, the first limiting structure, the second limiting structure, and the limiting member together define an installation space, and the battery is disposed within the installation space.

[0017] The battery pack provided in this application defines an installation space by defining a tray body, a first limiting structure, a second limiting structure, and a limiting member. Along the thickness direction of the tray body, at least one of the first limiting structure, the second limiting structure, and the limiting member has a flange extending towards the installation space at its end furthest from the tray body. This flange can limit the battery in the first direction, the second direction, and the thickness direction of the tray body, preventing displacement of the battery on the battery tray and avoiding abnormal noise caused by battery displacement. Simultaneously, the detachable connection between the limiting member and the tray body allows the limiting member to be installed on the tray body after the battery is inserted. This satisfies the requirement that the battery tray limits the battery in the first direction, the second direction, and the thickness direction of the tray body, while facilitating the assembly of the battery and the battery tray, making the assembly of the battery and the battery tray relatively simple and convenient.

[0018] Thirdly, embodiments of this application provide a vehicle including the aforementioned battery pack.

[0019] The vehicle provided in this application defines an installation space by defining a tray body, a first limiting structure, a second limiting structure, and a limiting member. Along the thickness direction of the tray body, at least one of the first limiting structure, the second limiting structure, and the limiting member has a flange extending towards the installation space at its end furthest from the tray body. This flange can limit the battery in the first direction, the second direction, and the thickness direction of the tray body, preventing displacement of the battery on the battery tray and avoiding abnormal noises caused by battery displacement. Simultaneously, the detachable connection between the limiting member and the tray body allows the limiting member to be installed on the tray body after the battery is inserted. This satisfies the requirement that the battery tray limits the battery in the first direction, the second direction, and the thickness direction of the tray body, while facilitating the assembly of the battery and the battery tray, making the assembly of the battery and the battery tray relatively simple and convenient.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0030] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0031] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0032] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0033] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0034] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] This application provides a vehicle. It should be noted that the vehicle in this application can refer to a large vehicle, a small vehicle, a special-purpose vehicle, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, vehicles are equipped with batteries.

[0036] It should be noted that the type of power source for the vehicle is not limited in this embodiment. For example, when the vehicle is a gasoline vehicle, the battery is mainly used to provide power to the starter motor, thereby starting the internal combustion engine; in addition, the battery also provides power to the vehicle's lighting system, audio system, ignition system, etc.; when the vehicle is a hybrid or electric vehicle, the battery can serve as the vehicle's power source to enable the vehicle to move.

[0037] The battery tray 100 provided in this embodiment is used to fix the battery.

[0038] For example, in some electric vehicles, the battery is located at the bottom of the vehicle, and at least a portion of the battery tray 100 is welded to the vehicle floor.

[0039] Based on this, refer to Figure 1 This application embodiment also provides a battery tray 100, including a tray body 1, a first limiting structure 2, a second limiting structure 3, and a limiting member 4.

[0040] Reference Figure 1 and Figure 2 To better illustrate the battery tray 100 provided in this application embodiment, the tray body 1, the first limiting structure 2, the second limiting structure 3, and the limiting member 4 together define an installation space 11 for installing batteries. The tray body 1 is positioned along a first direction (e.g., ...). Figure 1 Both ends of the first direction shown are provided with a first limiting structure 2. The first limiting structure 2 can limit the battery in the battery tray 100 at both ends of the first direction to prevent the battery from coming out of the installation space 11 in the first direction.

[0041] Reference Figure 1 and Figure 3The second limiting structure 3 is provided on the tray body 1 along the second direction (e.g., Figure 1 At one end of the second direction shown, the second limiting structure 3 can provide a limit for the battery in the battery tray 100 at one end of the second direction, so as to prevent the battery from coming out of the mounting space 11 at one end of the second direction.

[0042] Reference Figure 1 and Figure 2 The limiting member 4 is detachably provided at the other end of the tray body 1 along the second direction. The limiting member 4 can limit the battery in the battery tray 100 at the other end of the second direction to prevent the battery from coming out of the mounting space 11 at the other end of the second direction.

[0043] Among them, along the thickness direction of the tray body 1 (e.g. Figure 1 As shown in the third direction, at least one of the first limiting structure 2, the second limiting structure 3, and the limiting member 4 has a flange 32 extending toward the mounting space 11 at its end away from the tray body 1. The first direction, the second direction, and the thickness direction of the tray body 1 are perpendicular to each other. It is understood that the flange 32 and the tray body 1 are disposed opposite to each other in the thickness direction of the tray body 1. The flange 32 and the tray body 1 can provide a limit for the battery in the battery tray 100 in the thickness direction of the tray body 1, preventing the battery from coming out of the mounting space 11 in the thickness direction of the tray body 1.

[0044] At this time, the battery can be limited in the first direction, the second direction and the thickness direction of the tray body 1 to prevent the battery from shifting on the battery tray 100 and to avoid abnormal noise caused by battery displacement.

[0045] Meanwhile, the detachable connection between the limiting member 4 and the tray body 1 allows the limiting member 4 to be installed on the tray body 1 after the battery is inserted into the tray body 1. This satisfies the requirement that the battery tray 100 limits the battery in the first direction, the second direction, and the thickness direction of the tray body 1, while also facilitating the assembly of the battery with the battery tray 100. The assembly of the battery with the battery tray 100 is relatively simple and convenient.

[0046] According to the embodiments of this application, the battery tray 100 defines an installation space 11 by defining the tray body 1, the first limiting structure 2, the second limiting structure 3, and the limiting member 4. Along the thickness direction of the tray body 1, at least one of the first limiting structure 2, the second limiting structure 3, and the limiting member 4 has a flange 32 extending towards the installation space 11 at its end furthest from the tray body 1. This flange can limit the battery in the first direction, the second direction, and the thickness direction of the tray body 1, preventing displacement of the battery on the battery tray 100 and avoiding abnormal noise caused by battery displacement. Simultaneously, the limiting member 4 is detachably connected to the tray body 1, allowing the limiting member 4 to be installed on the tray body 1 after the battery is inserted. This satisfies the requirement that the battery tray 100 limits the battery in the first direction, the second direction, and the thickness direction of the tray body 1, while facilitating the assembly of the battery with the battery tray 100. The assembly of the battery with the battery tray 100 is relatively simple and convenient.

[0047] In addition, in this embodiment, the number of first limiting structures 2 is not limited. There can be multiple first limiting structures 2, as long as the first limiting structures 2 are provided on both sides of the pallet body 1 in the first direction.

[0048] Additionally, it should be noted that in the embodiments of this application, flanging refers to the formation of a straight wall or flange at a certain angle along a closed or open curved edge on the planar or curved portion of the blank. According to the flanging direction: it can be divided into vertical flanging, horizontal flanging, and inclined flanging. According to the number of flanging surfaces: it can be divided into single-sided flanging, multi-sided flanging, and closed curve flanging. According to the deformation nature: it can be divided into elongation flanging and compression flanging. Elongation flanging includes elongation-type planar curve flanging and elongation-type curved surface flanging; compression flanging includes compression-type planar curve flanging and compression-type curved surface flanging. According to the flanging form: it can be divided into internal hole flanging and external edge flanging.

[0049] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The limiting member 4 is provided with a wiring hole 41, which extends through the limiting member 4 along its thickness direction. The wiring harness connected to the battery can pass through the wiring hole 41, which can make the battery wiring neatly arranged, thereby increasing overall safety, avoiding messy battery wiring, and reducing the difficulty of battery inspection and maintenance. At the same time, if the wiring is mixed together, there is a risk of short circuits caused by the insulation layer melting due to heat during long-term use. By setting the wiring hole 41, the risk of accidents can be minimized and the battery safety can be increased.

[0050] In some embodiments of this application, the limiting member 4 and the tray body 1 are connected by fasteners, making the connection between the limiting member 4 and the tray body 1 simple and reliable. At the same time, the limiting member 4 can be easily removed from the tray body 1, making it easier to remove the battery from the battery tray 100.

[0051] In some embodiments of this application, reference is made to Figure 1 The limiting member 4 includes a first plate 42 and a second plate 43. One end face of the first plate 42 in the thickness direction is fitted and connected to the tray body 1, so that the fitting surface between the limiting member 4 and the tray body 1 is large, and the connection between the limiting member 4 and the tray body 1 is more reliable. The second plate 43 is located on the side of the first plate 42 near the installation space 11. There is an angle between the second plate 43, the first plate 42 and the tray body 1. That is, the second plate 43 and the first plate 42 are formed into an L-shape on the head surface in the first direction. After the battery and the battery tray 100 are assembled, at least a portion of the second plate 43 can abut against the end face of the battery near the limiting member 4 in the second direction, thereby limiting the battery.

[0052] In some embodiments of this application, reference is made to Figure 1 The first limiting structure 2 includes a first limiting plate 21, which is connected to the tray body 1. A limiting protrusion 22 is provided on the side of the first limiting plate 21 closest to the installation space 11. After the battery and battery tray 100 are assembled, the free end of the limiting protrusion 22 can abut against the battery, thus limiting the battery's position. Simultaneously, by setting the limiting protrusion 22, the contact area between the first limiting plate 21 and the battery can be reduced, avoiding excessive frictional resistance between the first limiting plate 21 and the battery when the battery is installed in the installation space 11, and preventing damage to the battery.

[0053] Furthermore, referring to Figure 1 There are multiple limiting protrusions 22, which are spaced apart along the second direction. The first limiting structure 2 is formed into a W-shaped structure on the projection surface of the tray body in the thickness direction. This can minimize the contact area between the first limiting plate 21 and the battery, and further avoid excessive frictional resistance between the first limiting plate 21 and the battery when the battery is installed in the installation space 11, thus avoiding damage to the battery.

[0054] In some embodiments of this application, reference is made to Figure 1 and Figure 3 The second limiting structure 3 includes a third plate 31, which is connected to the tray body 1. There is an angle between the third plate 31 and the tray body 1. After the battery and the battery tray 100 are assembled, at least a portion of the third plate 31 can stop against the end face of the battery that is close to the second limiting structure 3 along the second direction, thereby limiting the battery.

[0055] Reference Figure 1 and Figure 3The flange 32 is connected to the end of the third plate 31 away from the tray body 1. The flange 32 extends toward the direction close to the installation space 11. After the battery and the battery tray 100 are assembled, at least a portion of the flange 32 can stop the battery along the thickness direction of the tray body 1 at the end face of the tray body 1, thereby limiting the position of the battery.

[0056] In some embodiments of this application, the tray body 1, the first limiting structure 2, and the second limiting structure 3 are integrally formed. For example, the tray body 1, the first limiting structure 2, and the second limiting structure 3 can be formed using a single stamping die to achieve the required contours, holes, surface treatments, etc., thereby ensuring high precision and repeatability of the product. Simultaneously, this simplifies the production process of the battery tray 100, reduces the number of steps and required equipment during production, and thus lowers the production cost of the battery tray 100.

[0057] Additionally, in some embodiments of this application, reference is made to Figures 1-3 The end of the tray body 1 away from the limiting member 4 in the thickness direction is provided with a protrusion 12. The free end face of the protrusion 12 can be used for welding connection with external electrical equipment, increasing the reliability of the battery tray 100 assembly with other components.

[0058] The battery pack provided in this application embodiment includes a battery and a battery tray 100. The tray body 1, the first limiting structure 2, the second limiting structure 3 and the limiting member 4 together define the installation space 11. The battery is placed in the installation space 11, and the battery can be limited in the first direction, the second direction and the thickness direction of the tray body 1 to prevent the battery from being displaced on the battery tray 100 and to avoid abnormal noise caused by battery displacement.

[0059] According to the battery pack of this application embodiment, the mounting space 11 is defined by the tray body 1, the first limiting structure 2, the second limiting structure 3, and the limiting member 4. Along the thickness direction of the tray body 1, at least one of the first limiting structure 2, the second limiting structure 3, and the limiting member 4 has a flange 32 extending towards the mounting space 11 at its end away from the tray body 1. This flange can limit the battery in the first direction, the second direction, and the thickness direction of the tray body 1, preventing displacement of the battery on the battery tray 100 and avoiding abnormal noise caused by battery displacement. Simultaneously, the limiting member 4 is detachably connected to the tray body 1, allowing the limiting member 4 to be installed on the tray body 1 after the battery is inserted. This satisfies the requirement that the battery tray 100 limits the battery in the first direction, the second direction, and the thickness direction of the tray body 1, while facilitating the assembly of the battery with the battery tray 100. The assembly of the battery with the battery tray 100 is relatively simple and convenient.

[0060] The vehicle provided in this application embodiment includes the battery pack described above.

[0061] According to the vehicle embodiment of this application, the installation space 11 is defined by the tray body 1, the first limiting structure 2, the second limiting structure 3, and the limiting member 4. Along the thickness direction of the tray body 1, at least one of the first limiting structure 2, the second limiting structure 3, and the limiting member 4 has a flange 32 extending towards the installation space 11 at its end away from the tray body 1. This flange can limit the battery in the first direction, the second direction, and the thickness direction of the tray body 1, preventing displacement of the battery on the battery tray 100 and avoiding abnormal noise caused by battery displacement. Simultaneously, the limiting member 4 is detachably connected to the tray body 1, allowing the limiting member 4 to be installed on the tray body 1 after the battery is inserted. This satisfies the requirement that the battery tray 100 limits the battery in the first direction, the second direction, and the thickness direction of the tray body 1, while facilitating the assembly of the battery with the battery tray 100. The assembly of the battery with the battery tray 100 is relatively simple and convenient.
