Summary of the Invention

[0004] In view of the above, this application provides a power consumption device and its mounting base that can extend the service life of the mounting base.

The battery cell may be in the shape of a cylinder, a flat body, a cuboid or other shapes, etc., but the embodiments of the present application are not limited thereto. Generally, battery cells are classified into three types: cylindrical battery cells, prismatic battery cells, and soft bag battery cells according to their packaging methods, but the embodiments of the present application are not limited thereto.

[0029] The battery described in the embodiments of the present application refers to a single physical module that includes one or more battery cells to provide a higher voltage and capacity. For example, the battery described in the present application may include a battery module or a battery pack, etc. Generally, a battery includes a housing for packaging one or more battery cells. The housing can prevent liquids and other foreign substances from affecting the charging or discharging of the battery cells.

[0030] When the battery is used in a power-consuming device, it is usually attached to the mounting base of the power-consuming device. The mounting base supports the battery and is used to electrically connect the battery and the related functional modules in the power-consuming device.

[0031] After the inventors discovered that the probability of damage to the battery support structure in the mounting base was high after the battery was mounted on the mounting base of the power consumption device, they conducted a comprehensive analysis and research on the structure of the mounting base of the power consumption device and the assembly method between the mounting base and the power consumption device. As a result, after the battery is mounted on the mounting base, the mounting base supports the battery in a cantilever support manner. When the power consumption device is in use, loads such as impacts and vibrations applied to the battery are transmitted to the mounting base. However, since the mounting base supports the battery in a cantilever manner, the mounting base receives a large bending load, significantly reducing the load capacity of the mounting base. When loads such as impacts and vibrations act frequently, there is a risk of support failure and damage to the mounting base, which seriously affects the service life of the mounting base and also causes a risk of the battery detaching from the mounting base.

[0032] Based on the above problems found, the inventors have improved the structure of the mounting base, and the technical solution described in the embodiments of the present application is suitable for the mounting base and the power consumption device using the mounting base.

[0033] The power consumption device may be a vehicle, a mobile phone, a portable device, a notebook computer, a ship, a spacecraft, an electric toy, an electric tool, etc. The vehicle may be an engine-driven vehicle, a natural gas vehicle or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle or a range extender vehicle, etc. The spacecraft includes airplanes, rockets, space planes, spaceships, etc. The electric toy includes fixed or mobile electric toys, such as game consoles, electric vehicle toys, electric boat toys, electric airplane toys, etc. The electric tool includes metal cutting electric tools, grinding electric tools, assembly electric tools and railway electric tools, such as electric drills, electric grinders, electric wrenches, electric drivers, electric hammers, impact drills, concrete vibrators and electric shears, etc. In the embodiments of the present application, it is not particularly limited to the above power consumption device.

[0034] In the following embodiments, for the sake of convenience of description, the case where the power consumption device is a vehicle will be described as an example. FIG. 1 is a schematic structural diagram of a vehicle 1 according to some embodiments of the present application. As shown in FIG. 1, a battery 2 is provided inside the vehicle 1.

[0035] The battery 2 may be provided at the bottom, head or tail of the vehicle 1. The battery 2 can supply power to the vehicle 1. For example, the battery 2 may be used as an operating power source for the vehicle 1.

[0036] The vehicle 1 may further include a controller 11 and a motor 12. The controller 11 is configured to control the battery 2 to supply power to the motor 12. For example, it is used for the operating power requirements during the startup, navigation and driving of the vehicle 1.

[0037] In some embodiments of the present application, the battery 2 is not only used as an operating power source for the vehicle 1, but also used as a driving power source for the vehicle 1, and can provide driving force for the vehicle 1 by replacing or partially replacing fuel or natural gas.

[0038] FIG. 2 is an exploded schematic diagram of the battery 2 according to some embodiments of the present application. As shown in FIG. 2, the battery 2 includes a housing 21 and a battery cell (not shown), and the battery cell is housed in the housing 21.

[0039] The housing 21 is for accommodating battery cells and may have various structures. In some embodiments, the housing 21 may include a first portion 211 and a second portion 212. The first portion 211 and the second portion 212 are coupled to each other, and an accommodation chamber 21a for accommodating the battery module 3 is defined by both the first portion 211 and the second portion 212. The first portion 211 has a hollow structure with one end being an opening, and the second portion 212 has a plate-like structure. The housing 21 having the accommodation chamber 21a may be formed by covering the opening side of the first portion 211 with the second portion 212. Both the first portion 211 and the second portion 212 have a hollow structure with one side being open, and the opening side of the first portion 211 is covered by the opening side of the second portion 212, whereby the housing 21 having the accommodation chamber 21a may be formed. Of course, the first portion 211 and the second portion 212 may have various shapes such as a cylindrical body or a rectangular parallelepiped.

[0040] When the first portion 211 is covered on the top of the second portion 212, the first portion 211 may be referred to as an upper cover, and the second portion 212 may be referred to as a lower housing 21.

[0041] In the battery 2, there may be one or a plurality of battery cells. When there are a plurality of battery cells, the plurality of battery cells may be connected in series, in parallel, or in series-parallel with each other. Series-parallel connection means that among the plurality of battery cells, some are connected in series and some are connected in parallel. After directly connecting a plurality of battery cells in series, in parallel, or in series-parallel to integrate them, the whole composed of the plurality of battery cells may be accommodated in the housing 21. Of course, a plurality of battery cells may be connected in series, in parallel, or in series-parallel to form the battery module 3, and the integrated product formed by connecting a plurality of battery modules 3 in series, in parallel, or in series-parallel may be accommodated in the housing 21.

[0042] Figure 3 is a schematic structural diagram of the battery module 3 shown in Figure 2.

[0043] In some embodiments, as shown in FIG. 3, there are a plurality of battery cells 31, and the plurality of battery cells 31 are connected in series, in parallel, or in series-parallel to form a battery module 3. Further, the plurality of battery modules 3 are connected in series, in parallel, or in series-parallel to be integrated and housed in a housing.

[0044] The plurality of battery cells 31 in the battery module 3 are electrically connected to each other by bus bars to realize parallel connection, series connection, or series-parallel connection of the plurality of battery cells 31 in the battery module 3.

[0045] As shown in FIGS. 4 to 6, the mounting base 4 of the power consumption device according to the embodiment of the present application is used to mount the battery 2, and the mounting base 4 includes a base body 41, a support assembly 42, and a locking mechanism 43. The support assembly 42 is provided on the base body 41, and the support assembly 42 includes a first support base 421 and a second support base 422 provided at intervals. The locking mechanism 43 is provided on the base body 41, and the locking mechanism 43 penetrates through a portion of the battery 2 that enters between the first support base 421 and the second support base 422 and is supported by the first support base 421 and the second support base 422, and includes a locking shaft 431 for fixing the battery 2.

[0046] Specifically, the mounting base 4 is attached to the power consumption device, is used to place and position the battery 2. Further, in order to electrically connect the battery 2 and related functional modules and enable the battery 2 to normally supply power to the power consumption device, other functional modules may be integrated on the mounting base 4. The specific form of the structure of the mounting base 4 is not limited, as long as the battery 2 can be mounted. Taking the case where the power consumption device is a vehicle as an example, the mounting base 4 may be fixed to the vehicle chassis.

[0047] The base body 41 may be structured such that it is connected to the power consumption device and integrated with functional modules such as control elements, may be a plate-like structure, or may be a structure formed by joining rod-like structures, and may be determined according to specific needs.

[0048] When the battery 2 is attached to the mounting base 4, the battery 2 is directly supported by the locking shaft 431 of the locking mechanism 43. The locking shaft 431 is supported between the first support base 421 and the second support base 422 of the support assembly 42, and the support portion of the locking shaft 431 with respect to the battery 2 is between the first support base 421 and the second support base 422. In this way, effective support is obtained on both sides of the support point of the locking shaft 431 with respect to the battery 2, and the locking shaft 431 is supported at two points. Compared with the technical solution where the locking shaft 431 is cantilever-supported, that is, only one side of the support portion of the locking shaft 431 with respect to the battery 2 is effectively supported and the other side is hanging, in the technical solution of two-point support, under the action of the same load such as impact and vibration, it is possible to make the support assembly 42 support the locking shaft 431 at two points, which can reduce the bending load borne by the locking shaft 431 more effectively.

[0049] The first support base 421 and the second support base 422 each have a support surface. Specifically, the support surface is a surface that engages with the locking shaft 431, and it may be a flat surface, a curved surface, or a cylindrical surface, and may be determined according to actual needs. The first support base 421 and the second support base 422 may each be independently provided on the base body 41, or both may be integrally connected and provided on the base body 41.

[0050] As a method for the locking shaft 431 to penetrate the battery 2, the locking shaft 431 may be provided through the sealing structure of the battery 2. For example, it may be provided through the sealed cylindrical surface of the battery 2, or it may be provided through the semi-sealed structure of the battery 2. For example, it may be provided through the semi-sealed semi-cylindrical surface of the battery 2. Specifically, it may be determined according to actual needs.

[0051] Optionally, a locking member 22 may be provided on the side of the battery 2 close to the mounting base 4, and the locking shaft 431 may be provided through the locking member 22 of the battery 2.

[0052] The support of the battery 2 by the lock shaft 431 may be either line contact or surface contact. The support position of the battery 2 by the lock shaft 431 may be the same or different in terms of the distances from the first support base 421 and the second support base 422. When the support position of the battery 2 by the lock shaft 431 is at the center between the first support base 421 and the second support base 422, the bending moments received on both sides of the lock shaft 431 become closer. Thus, it is understood that when the external load action is the same, the bending load received by the lock shaft 431 is minimized.

[0053] In the mounting base 4 according to the embodiment of the present application, the support assembly 42 includes a first support base 421 and a second support base 422 that jointly support the lock shaft 431, and the support position of the battery 2 by the lock shaft 431 is configured to be between the first support base 421 and the second support base 422. As a result, under the same load actions such as impact and vibration, the bending moment received by the lock shaft 431 is small, the load capacity of the lock shaft 431 is high, and the service life of the mounting base 4 is extended.

[0054] The support method of the lock shaft 431 by the first support base 421 and the second support base 422 may be surface contact, line contact, etc. As an example, when the part of the lock shaft 431 that contacts the first support base 421 or the second support base 422 is cylindrical, the corresponding part of the first support base 421 or the second support base 422 may be a plane, a semi-closed semi-cylindrical surface that engages with the lock shaft 431, or a closed cylindrical surface that engages with the lock shaft 431, etc. It is not limited here and may be determined according to actual needs.

[0055] In some preferred embodiments, as shown in FIG. 7, the first support base 421 has a first support hole 421a through which the lock shaft 431 is inserted.

[0056] When the power consumption device operates, the impact received by the battery 2 and the direction of the vibration load may be in various directions. Therefore, it is understood that the load direction of the locking shaft 431 by the battery 2 and the first support base 421 by the locking shaft 431 may also be in various directions. By configuring the first support base 421 to have the first support hole 421a, the first support base 421 can receive loads in various directions of the first support base 421 by the locking shaft 431, thereby further improving the load capacity of the mounting base 4.

[0057] In some embodiments, as shown in FIG. 7, the second support base 422 has a second support hole 422a through which the locking shaft 431 is inserted.

[0058] Similar to the case where the first support base 421 is provided with the first support hole 421a, by configuring the second support base 422 to have the second support hole 422a, the second support base 422 can further receive loads in various directions, thereby improving the load capacity of the mounting base 4.

[0059] In some embodiments, as shown in FIGS. 8 and 9, the locking shaft 431 is provided to be inclined in a direction approaching the battery in the extending direction of the locking shaft 431, and has an inclined section 4311 for engaging with the wedge 221 of the battery.

[0060] Specifically, the extending direction of the locking shaft 431 described in this specification is the direction in which the locking shaft 431 extends and is inserted into the battery and is supported by the first support base 421 and the second support base 422. The wedge 221 may be formed in a locking member 22 that engages with the locking shaft 431 in the battery and is a block for engaging with the inclined section 4311. By having the inclined direction of the wedge 221 opposite to the inclined direction of the inclined section 4311, the two can be well adhered to each other.

[0061] As can be understood, due to the deviation in the processing accuracy of the locking shaft 431 and the battery, after the locking shaft 431 is inserted into the battery, it is impossible to ensure that the locking shaft 431 is in good contact with the battery. By configuring the inclined section 4311 of the locking shaft 431 to engage with the wedge 221 of the battery, in the process of inserting the locking shaft 431 into the battery along the extending direction, by setting the specific extending length and distance of the locking shaft 431 according to the actual needs, it can be ensured that the locking shaft 431 is in good engagement with the battery. Thereby, the requirement for the processing accuracy of the engagement part between the battery and the locking shaft 431 can be reduced, and the production cost can be reduced.

[0062] The inclined section 4311 may be integrally formed and configured to have an appropriate inclination angle.

[0063] In some preferred embodiments, as shown in FIGS. 8 to 10, the inclined section 4311 includes a first sub-section 431a and a second sub-section 431b, and the first sub-section 431a and the second sub-section 431b are distributed in a stepped manner.

[0064] Specifically, the corresponding surfaces of the first sub-section 431a and the second sub-section 431b may be parallel to each other or may have different inclination angles. By providing the first sub-section 431a and the second sub-section 431b in a stepped manner, if the first sub-section 431a cannot engage with the wedge 221, by moving the locking shaft 431 a small distance in the extending direction, the second sub-section 431b can be engaged with the wedge 221. According to such a configuration, the difficulty of installing the battery 2 can be effectively reduced.

[0065] When battery positioning is required, the locking shaft 431 may be extended and moved along the extending direction and configured to be inserted into the battery. When it is necessary to remove the battery from the power consumption device, the locking shaft 431 may be retracted to release the locking action on the battery. Extending and moving the locking shaft 431 may be achieved manually or mechanically, but it is not limited here and may be determined according to actual needs.

[0066] In some embodiments, the locking mechanism 43 further includes a driving member 432 connected to the locking shaft 431 and configured to drive the locking shaft 431 to move.

[0067] Specifically, the driving member 432 can realize positioning the locking member 22 of the battery by driving the locking shaft 431 to extend and move along the extending direction. When it is necessary to remove the battery from the mounting base 4, the driving unit can drive the locking shaft 431 to retract to unlock the battery from the mounting base 4. By providing the driving member 432 for driving the locking shaft 431 to move, the movement of the locking shaft 431 can be made more labor-saving and easier.

[0068] As can be understood, the driving member 432 may have a structure such as an air cylinder, a hydraulic cylinder or a motor. As an example, the driving member 432 is a hydraulic cylinder, the locking shaft 431 is connected to the piston rod, and the extension or retraction of the piston rod can realize the positioning or release of the positioning of the battery by the locking shaft 431.

[0069] The locking shaft 431 may be exposed to the external environment, or a protective cover may be provided on the locking shaft 431 to protect the locking shaft 431.

[0070] In some preferred embodiments, the locking mechanism 43 further includes a sleeve 433 externally fitted on the locking shaft 431, and the locking shaft 431 can extend from the sleeve 433.

[0071] Specifically, when there is no need to support and position-regulate the battery, the lock shaft 431 is retracted into the sleeve 433, and when it is necessary to support the battery, it extends from the sleeve 433. By providing the sleeve 433, the lock shaft 431 is protected, and the risk that external particles, dust, etc. enter the expansion and contraction counterpart of the lock shaft 431 and cause the lock shaft 431 to get stuck can be reduced. Further, the sleeve 433 provides guidance for the movement of the lock shaft 431 during the movement process of the lock shaft 431, and the risk that the lock shaft 431 deviates can be reduced.

[0072] The sleeve 433 may be provided separately from the first support base 421 and the second support base 422, or may be provided connected to each other, but is not limited here.

[0073] In some preferred embodiments, the first support base 421 is connected to the sleeve 433, and the second support base 422 is connected to the first support base 421.

[0074] According to such a configuration, the first support base 421, the second support base 422, and the sleeve 433 are integrally connected and provided on the base body 41, thereby improving the integrity of the internal structure of the mounting base 4. By connecting these three, the movement accuracy of the lock shaft 431 can be improved, and the engagement accuracy between the lock shaft 431 and the battery can be improved.

[0075] Depending on the support method of the battery by the mounting base 4, the mounting base 4 may include one or a plurality of locking mechanisms 43. In embodiments where the mounting base 4 includes a plurality of locking mechanisms 43, the distribution forms of the plurality of locking mechanisms 43 are various. For example, they may be distributed in one row, or may be distributed in two rows or a plurality of rows. The load capacity of the mounting base 4 for the battery can be specifically set according to actual needs.

[0076] In some embodiments, as shown in FIGS. 11 and 12, the mounting base 4 includes a plurality of locking mechanisms 43, and the plurality of locking mechanisms 43 are provided on the base body 41 at intervals.

[0077] As can be understood, when the weight of the battery is constant, by providing a plurality of locking mechanisms 43, the load exerted by the battery on the mounting base 4 is shared by the plurality of locking mechanisms 43, so that the load of the battery received by one locking mechanism 43 can be reduced. According to such a configuration, the load capacity of the mounting base 4 can be improved, and the service life of the mounting base 4 can be extended.

[0078] In some embodiments, the battery is supported on the mounting base 4 along the first direction X. The battery has a first surface provided oppositely in the second direction Y and a second surface provided in the third direction Z, and the first surface is connected to the two second surfaces. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0079] Specifically, the first direction X may be the vertical direction, and the second direction Y and the third direction Z may be the horizontal directions. The locking shaft 431 may extend and move along the second direction Y, or may extend and move along the third direction Z, or may extend and move along other directions. When the mounting base 4 includes a plurality of locking mechanisms 43, the plurality of locking mechanisms 43 may be provided at intervals in the second direction Y, or may be provided at intervals in the third direction Z. The locking mechanisms 43 may be provided in pairs and may be provided on both sides of the battery along the second direction Y or the third direction Z, respectively.

[0080] In some preferred embodiments, the mounting base 4 includes two locking mechanisms 43, and the two locking mechanisms 43 are provided at intervals in the second direction Y. The axial direction of the locking shaft 431 is along the second direction Y, and the extending directions of the two locking shafts 431 are opposite.

[0081] According to such a configuration, the supporting forces of the battery by the two locking mechanisms 43 may be provided as symmetrically as possible with respect to the center of gravity of the battery. Thereby, the load balance of the battery with respect to the mounting base 4 is better achieved, and the overturning moment received by the battery can be reduced.

[0082] In some other embodiments, the mounting base 4 includes a plurality of pairs of locking mechanisms 43. Each pair of locking mechanisms 43 is provided at an interval in the second direction Y. The plurality of pairs of locking mechanisms 43 are provided at an interval in the third direction Z. The axial direction of the locking shaft 431 is along the second direction, and the extending directions of the locking shafts 431 of each pair of locking mechanisms 43 are opposite.

[0083] It should be noted that each locking mechanism 43 corresponds to one support assembly 42. Since a plurality of pairs of locking mechanisms 43 are provided, in order to support the locking shafts 431 of each locking mechanism 43, it is necessary to install a plurality of pairs of support assemblies 42.

[0084] As can be understood, by including a plurality of pairs of locking mechanisms 43 in the mounting base 4, the load capacity of the battery by the mounting base 4 can be improved, and the force received by the locking shaft 431 of each locking mechanism 43 can be reduced. By configuring the extending directions of the plurality of pairs of locking mechanisms 43 to be opposite, the balance of the forces received by the battery is better achieved.

[0085] In some embodiments, the mounting base 4 further includes a guiding and positioning mechanism 44 provided on the base body 41. The guiding and positioning mechanism 44 is used to guide the movement of the battery and position the battery.

[0086] Understandably, before the step of inserting the locking shaft 431 into the battery, it is necessary to position the battery at a predetermined position on the mounting base 4 to ensure the accuracy of the battery mounting position. Therefore, by providing the guiding and positioning mechanism 44, when the battery is placed on the mounting base 4, the moving direction of the battery can be guided, and the situation of repeatedly adjusting the position of the battery after it is placed on the mounting base 4 can be avoided. When the battery is placed at the desired position, the guiding and positioning mechanism 44 can easily position the battery and reduce the risk of misalignment occurring after the battery is placed on the mounting base 4. Therefore, by providing the guiding and positioning mechanism 44, the mounting accuracy and mounting efficiency of the battery can be effectively improved.

[0087] The specific structure of the guiding and positioning mechanism 44 is not limited. As long as it can provide guidance for the movement of the battery and can exert a certain positioning effect on the battery after the battery is placed at the desired position.

[0088] In some preferred embodiments, the guiding and positioning mechanism 44 includes a guide member 441 and a positioning pin 442. The guide member 441 has a guide surface 441a for guiding the movement of the battery. The positioning pin 442 is engaged with the positioning hole of the battery and is used to position the battery.

[0089] Specifically, the guide surface 441a may be an inclined surface provided to incline in the direction towards the mounting base 4. When the battery moves towards the mounting base 4, it can contact the guide surface 441a and move along the guide surface 441a. When the battery moves along the guide surface 441a, the positioning hole of the battery gradually engages with the positioning pin 442. After the battery moves to the desired position, the positioning pin 442 plays a role in positioning the battery. Therefore, by configuring the guiding and positioning mechanism 44 to include the guide member 441 and the positioning pin 442, the functions of guiding and positioning in the process of mounting the battery with a simple structure can be exerted.

[0090] The number of the guide members 441 and the positioning pins 442 is not limited. As an example, guide members 441 are provided at positions corresponding to the four opposite sides of the battery and the mounting base 4, and two positioning pins 442 are provided at positions corresponding to the diagonal lines opposite to each other between the battery and the mounting base 4, thereby making the guidance for the battery more accurate and further improving the mounting efficiency of the battery.

[0091] The power consumption device according to the embodiment of the present application includes a battery and a mounting base 4 according to any one of the above embodiments. A part of the battery enters between the first support base 421 and the second support base 422, and the lock shaft 431 penetrates through the part that enters between the first support base 421 and the second support base 422 of the battery and is supported by the first support base 421 and the second support base 422 to fix the battery.

[0092] Unless there is a contradiction, the embodiments and the configurations of the embodiments of the present application may be combined with each other.

[0093] It should be noted that the above embodiments are only used to explain the technical solution of the present application and do not limit it. Although the present application has been described in detail with reference to the foregoing embodiments, as can be understood by those skilled in the art, the technical solutions described in the foregoing embodiments can be modified or some of their technical features can be equivalently replaced, and these modifications or replacements do not cause the gist of the corresponding technical solutions to deviate from the gist and scope of the technical solutions of the embodiments of the present application.
