Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to battery devices, connectors and electrical equipment. Background Art

[0002] Connectors are used in power batteries, energy storage batteries, electronic appliances, mechanical devices and other fields to achieve electrical connections between batteries and between batteries and electrical devices. Batteries are usually electrically connected to other devices through connectors, so that the battery can power other devices or be charged by other devices.

[0003] The connector includes a connector cover and a connector base. When the connector cover and the connector base are docked, the docking is often not in place, resulting in a problem of a poor connection between the two. Utility Model Content

[0004] Based on this, it is necessary to provide a battery device, a connector and an electrical device that can accurately determine whether the connector cover and the connector seat of the connector are properly docked to avoid the connector cover and the connector seat being put into operation in a virtual connection state.

[0005] In a first aspect, the present application provides a battery device, including a box, a battery cell group and a connector, wherein the battery cell group is disposed in the box, and the connector is disposed on the box, wherein the connector includes:

[0006] Connector housing;

[0007] A connector cover body configured to mate with a connector seat body;

[0008] A locking member, disposed on the connector base and / or the connector cover, and used to lock the connector cover and the connector base after the connector cover and the connector base are mated in place; and

[0009] The elastic member is arranged on the connector seat and / or the connector cover, and is used to make the unlocked connector cover separate from the connector seat.

[0010] The battery device provided in the embodiment of the present application realizes electrical connection with the battery cell group in the box body by arranging a connector on the box body, and realizes electrical connection between the battery cell group and the external device through the connector. The connector includes a connector seat and a connector cover body, and the connector seat body and the connector cover body are matched to realize electrical connection inside the connector. By arranging a locking member, the connector seat body and the connector cover body matched in place are locked to prevent the connector seat body and the connector cover body from being disconnected. By arranging an elastic member, the connector cover body that is not locked by the locking member is separated from the connector seat body, so that it can be more intuitively observed that the connector cover body and the connector seat body are not docked in place, reminding the operator to continue the operation and insert the connector cover body into the connector seat body until the locking member locks the connector seat body and the connector cover body, so as to prevent the connector seat body and the connector cover body from being put into operation in a virtual connection state.

[0011] In some embodiments, the elastic member is sandwiched between the connector cover and the connector base, and is located on an end surface of the connector base and / or the connector cover that is perpendicular to the mating movement direction.

[0012] In the battery device provided in the embodiment of the present application, during the mating and moving process between the connector cover and the connector seat, the elastic member is triggered, thereby exerting a force on the connector cover to drive it away from the connector seat.

[0013] In some embodiments, the elastic member is constructed as an elastic member, which can apply an elastic force along the mating movement direction to the connector cover and / or the connector seat, and the elastic force is smaller than the locking force of the locking member on the connector cover and the connector seat.

[0014] In the battery device provided in the embodiment of the present application, the elastic member can exert an ejection force on the connector cover to eject the unlocked connector cover out of the connector seat. When the connector cover is locked in the connector seat, since the elastic force exerted by the elastic member on the connector cover is less than the locking force exerted by the locking member on the connector cover and the connector seat, the elastic member cannot eject the connector cover out of the connector seat, thereby keeping the connector cover and the connector seat in a docking state.

[0015] In some embodiments, a plurality of elastic members are provided, and all of the elastic members are spaced apart on the connector seat and / or the connector cover.

[0016] The battery device provided in the embodiment of the present application provides driving force to the connector seat and the connector cover through a plurality of elastic members to improve foolproof reliability.

[0017] In some embodiments, the elastic member is disposed on an end surface of the connector seat and / or the connector cover, the end surface has a plurality of corners, and the elastic member is disposed on at least some of the corners.

[0018] In the battery device provided in the embodiment of the present application, the range surrounded by the multiple elastic members is relatively large, and the ejection force on the connector cover is relatively uniform, which is conducive to the connector cover being relatively smoothly withdrawn from the connector seat.

[0019] In some embodiments, the elastic member includes:

[0020] A telescopic rod, a first end of which is connected to one of the connector base and the connector cover;

[0021] The telescopic driving member is used to drive the telescopic rod to extend so that the second end of the telescopic rod moves in a direction away from the first end.

[0022] In the battery device provided in the embodiment of the present application, when the second end of the telescopic rod moves in a direction away from the first end, it presses the connector seat or the connector cover to which the second end is facing, thereby driving the connector seat and the connector cover to move relative to each other, so as to push the connector cover out of the connector seat.

[0023] In some embodiments, the telescopic driving member is configured as a spring, and the first end and the second end of the telescopic rod are respectively provided with limiting protrusions, and the two ends of the spring are respectively abutted against the limiting protrusions of the first end and the second end.

[0024] The battery device provided in the embodiment of the present application limits the spring to a position sleeved on the outside of the telescopic rod, and utilizes the elastic force of the spring to drive the second end to move.

[0025] In some embodiments, the elastic member further comprises:

[0026] The guide sleeve is connected to the connector seat body or the connector cover body. The telescopic rod and the spring are partially confined in the guide sleeve, and the other parts extend out of the guide sleeve.

[0027] The battery device provided in the embodiment of the present application can provide limitation and guidance for the extension and contraction of the spring through the guide sleeve, thereby preventing the spring from being twisted when being compressed by the limiting protrusion.

[0028] In some embodiments, the locking member is configured as a snap-fit ​​member to snap-fit ​​and lock the connector base and the connector cover.

[0029] The battery device provided in the embodiment of the present application realizes a firm connection between the connector seat and the connector cover by adopting a clamping member.

[0030] In a second aspect, the present application further provides a connector, the connector comprising:

[0031] Connector housing;

[0032] A connector cover body configured to mate with a connector seat body;

[0033] A locking member, disposed on the connector base and / or the connector cover, and used to lock the connector cover and the connector base after the connector cover and the connector base are mated in place; and

[0034] The elastic member is arranged on the connector seat and / or the connector cover, and is used to make the unlocked connector cover separate from the connector seat.

[0035] In a third aspect, the present application also provides an electrical device, comprising the battery device as described above.

[0057] At present, judging from the development of the market situation, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars and other fields. With the continuous expansion of battery application areas, the market demand is also constantly expanding.

[0058] In battery systems in various fields, battery connectors are crucial components responsible for achieving electrical connections between batteries and between batteries and electrical devices. The connector includes a connector cover and a connector base. The docking reliability of the connector cover and the connector base directly affects the reliability of the electrical connection. Therefore, how to effectively improve the docking reliability of the connector cover and the connector base is an urgent problem to be solved in battery technology.

[0059] The inventor of the present application has noticed that the connector cover and the connector seat are generally docked by snap-fitting. During the docking process, whether the connector cover is plugged in is mainly judged by human visual observation, snap-fitting sound, and pulling back the connector cover, which places relatively high requirements on the technical specifications of the operator and the environment of the operation site. If the operator does not observe carefully, the pull-back force is insufficient, or the snap-fitting sound is muffled due to environmental operation, the judgment will be inaccurate. Therefore, the problem of the connector cover not being properly plugged into the connector seat often occurs, resulting in a virtual connection between the two, and then causing unreliable electrical connection.

[0060] After research, the inventor of the present application discovered that an elastic member can be provided between the connector cover and the connector seat. When the connector cover and the connector seat are not properly plugged in, the elastic member will limit the connector cover to stay in the connector seat, and it can be clearly observed that the connector cover and the connector seat are not docked, thereby reminding the operator to continue the operation and fully plug the connector cover into the connector seat to avoid the two being put into operation in a virtual connection state.

[0061] Based on such a design concept, the inventor of the present application has designed a battery device, including a box body, a battery cell group and a connector, wherein the battery cell group is arranged in the box body, and the connector is arranged on the box body. The connector includes a connector seat, a connector cover, a locking member and an elastic member, and the connector cover is configured to be matched with the connector seat. The locking member is arranged on the connector seat and / or the connector cover, and the locking member is used to lock the connector cover and the connector seat after the connector cover and the connector seat are matched in place. The elastic member is arranged on the connector seat and / or the connector cover, and is used to disengage the unlocked connector cover from the connector seat. By arranging the elastic member on the connector seat and / or the connector cover, the connector cover that is not locked by the locking member is disengaged from the connector seat, so that it can be more intuitively observed that the connector cover and the connector seat are not plugged in place.

[0062] The embodiment of the present application also provides an electric device, which provides electric energy through the above-mentioned battery device. The electric device can be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, etc. Among them, the electric toy can include a fixed or mobile electric toy, for example, a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc., and the spacecraft can include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0063] In some embodiments, the power-consuming device may be a vehicle. The vehicle may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery device is provided inside the vehicle, and the battery device may be provided at the bottom, head or tail of the vehicle. The battery device may be used to power the vehicle, for example, the battery device may be used as an operating power source for the vehicle. The vehicle may also include a controller and a motor, and the controller may be used to control the battery device to power the motor. For example, the battery device may be used for starting, navigating and operating power requirements of the vehicle during driving.

[0064] The structures of the battery device, connector and electrical equipment provided in the embodiments of the present application are described below in conjunction with the accompanying drawings.

[0065] Please refer to Figure 1 , Figure 1A schematic diagram of the structure of a vehicle 1000 provided for some embodiments of the present application. Taking the vehicle 1000 as an example, the electrical equipment may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery device 100 is provided inside the vehicle 1000, and the battery device 100 may be provided at the bottom, head or tail of the vehicle 1000. The battery device 100 may be used to power the vehicle 1000, for example, the battery device 100 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300, and the controller 200 is used to control the battery device 100 to power the motor 300, for example, for starting, navigating and driving the vehicle 1000.

[0066] In some embodiments, the battery device 100 can be used not only as an operating power source for the vehicle 1000 , but also as a driving power source for the vehicle 1000 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000 .

[0067] Please refer to Figure 2 , Figure 2 The schematic diagram of the structure of the battery device 100 provided in some embodiments of the present application. In some embodiments, the battery device 100 includes a box body 10 and a battery cell group 20 . The battery cell group 20 generally includes a plurality of battery cells. The battery cell group 20 is accommodated in the box body 10 .

[0068] The box 10 is used to provide a storage space for the battery cell group 20, and the box 10 can adopt a variety of structures. In some embodiments, the box 10 may include a first part 11 and a second part 12, the first part 11 and the second part 12 cover each other, and the first part 11 and the second part 12 jointly define a storage space for accommodating the battery cell group 20. The second part 12 may be a hollow structure with one end open, and the first part 11 may be a plate-like structure, and the first part 11 covers the open side of the second part 12, so that the first part 11 and the second part 12 jointly define a storage space; the first part 11 and the second part 12 may also be hollow structures with one side open, and the open side of the first part 11 covers the open side of the second part 12. Of course, the box 10 formed by the first part 11 and the second part 12 can be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0069] Please refer to Figure 2In the battery device 100, there may be multiple battery cell groups 20, and the multiple battery cell groups 20 may be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cell groups 20 are both connected in series and in parallel. The multiple battery cell groups 20 may be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cell groups 20 is accommodated in the box 10; of course, the battery device 100 may also be a battery module formed by connecting multiple battery cells in series, in parallel, or in mixed connection, and then the multiple battery modules are connected in series, in parallel, or in mixed connection to form a whole, and accommodated in the box 10. The battery device 100 may also include other structures, for example, the battery device 100 may also include a busbar component for realizing electrical connection between the multiple battery cell groups 20.

[0070] See also Figure 3 and Figure 4 , Figure 3 A schematic diagram of the structure of a connector 30 provided in some embodiments of the present application is shown; Figure 4 A schematic structural diagram of a connector seat 1 provided in some embodiments of the present application is shown.

[0071] The embodiment of the present application provides a battery device 100, including a box body 10, a battery cell group 20 and a connector 30, wherein the battery cell group 20 is arranged in the box body 10, and the connector 30 is arranged on the box body 10. The connector 30 includes a connector seat body 1, a connector cover body 2, a locking member 3 and an elastic member 4, wherein the connector cover body 2 is configured to be matched with the connector seat body 1. The locking member 3 is arranged on the connector seat body 1 and / or the connector cover body 2, and the locking member 3 is used to lock the connector cover body 2 and the connector seat body 1 after the connector cover body 2 and the connector seat body 1 are matched in place. The elastic member 4 is arranged on the connector seat body 1 and / or the connector cover body 2, and the elastic member 4 is used to make the unlocked connector cover body 2 detach from the connector seat body 1.

[0072] The battery device 100 proposed in the embodiment of the present application realizes electrical connection with the battery cell group 20 in the box body 10 by setting a connector 30 on the box body 10, and realizes electrical connection between the battery cell group 20 and the external device through the connector 30. The connector 30 includes a connector seat 1 and a connector cover 2, and the connector seat 1 and the connector cover 2 are matched to realize electrical connection inside the connector 30. By setting a locking member 3, the connector seat 1 and the connector cover 2 matched in place are locked to prevent the connector seat 1 and the connector cover 2 from being disconnected. By setting an elastic member 4, the connector cover 2 that is not locked by the locking member 3 is separated from the connector seat 1, so that it can be more intuitively observed that the connector cover 2 and the connector seat 1 are not docked in place, reminding the operator to continue the operation and insert the connector cover 2 into the connector seat 1 until the locking member 3 locks the connector seat 1 and the connector cover 2 to prevent the connector seat 1 and the connector cover 2 from being put into operation in a virtual connection state.

[0073] Specifically, the connector 30 can be used to achieve connection between battery cell groups 20, between battery cell groups 20 and other electrical components, or in any structure where electrical connection is required within the battery device 100.

[0074] In some embodiments, such as Figure 4 As shown, the elastic member 4 is sandwiched between the connector cover 2 and the connector base 1, and is located on the end surface of the connector base 1 and / or the connector cover 2 that is perpendicular to the mating movement direction. In this way, during the mating movement of the connector cover 2 and the connector base 1, the elastic member 4 will be triggered, thereby exerting a force on the connector cover 2 to drive it away from the connector base 1.

[0075] Optionally, the elastic member 4 can be arranged on the connector cover 2, and along with the connector cover 2, synchronously moves toward the connector base 1, gradually making the elastic member 4 abut against the connector base 1, so as to achieve the clamping of the elastic member 4 by the connector cover 2 and the connector base 1. It is understandable that the elastic member 4 can also be arranged on the connector base 1, and along with the matching action of the connector cover 2 and the connector base 1, the clamping of the elastic member 4 by the connector cover 2 and the connector base 1 can also be achieved. Alternatively, at least one elastic member 4 can be arranged on each of the connector base 1 and the connector cover 2.

[0076] In some embodiments, a plurality of elastic members 4 are provided, and all elastic members 4 are arranged at intervals on the connector base 1 and / or the connector cover 2. The plurality of elastic members 4 provide driving force to the connector base 1 and the connector cover 2 to improve foolproof reliability.

[0077] Exemplarily, the elastic member 4 is disposed on an end face of the connector housing 1 and / or the connector cover 2, the end face has a plurality of corners, and the elastic member 4 is disposed on at least some of the corners. In this way, the range surrounded by the plurality of elastic members 4 is larger, and the ejection force on the connector cover 2 is more uniform, which is conducive to the connector cover 2 being more smoothly withdrawn from the connector housing 1.

[0078] For example, the connector base 1 is provided with a plug-in slot 101 for accommodating the connector cover 2. The plug-in slot 101 is arranged in a rectangular shape and has four corners, and an elastic member 4 is arranged at each corner. The connector cover 2 has four corners correspondingly, and the elastic member 4 applies an ejection force to the four corners of the connector cover 2, so that it is easier to eject the connector cover 2 from the connector base 1. Of course, the elastic member 4 can also be arranged on the four corners of the connector cover 2, or a part of the multiple elastic members 4 can be arranged on the corners of the connector base 1, and another part of the elastic members 4 can be arranged on the corners of the connector cover 2. Preferably, the elastic member 4 on the connector base 1 and the elastic member 4 on the connector cover 2 are arranged in a staggered manner.

[0079] In some embodiments, the elastic member 4 can exert an elastic force on the connector cover 2 and / or the connector seat 1 along the mating movement direction, and the elastic force is smaller than the locking force of the locking member 3 on the connector cover 2 and the connector seat 1. In this way, the elastic member 4 can exert an ejection force on the connector cover 2 to eject the unlocked connector cover 2 out of the connector seat 1. When the connector cover 2 is locked in the connector seat 1, since the elastic force of the elastic member 4 on the connector cover 2 is smaller than the locking force of the locking member 3 on the connector cover 2 and the connector seat 1, the elastic member 4 will not be able to eject the connector cover 2 out of the connector seat 1, thereby keeping the connector cover 2 and the connector seat 1 in a docking state.

[0080] See also Figure 5 and Figure 6 , Figure 5 A schematic diagram of the structure of the elastic member 4 provided in some embodiments of the present application is shown; Figure 6 A schematic cross-sectional structure diagram of the elastic member 4 provided in some embodiments of the present application is shown.

[0081] In some embodiments, the elastic member 4 includes a telescopic rod 41 and a telescopic driving member 42, wherein the first end of the telescopic rod 41 is connected to one of the connector seat 1 and the connector cover 2. The telescopic driving member 42 is used to drive the telescopic rod 41 to extend so that the second end of the telescopic rod 41 moves in a direction away from the first end. In this way, when the second end of the telescopic rod 41 moves in a direction away from the first end, the connector seat 1 or the connector cover 2 facing the second end is pressed, thereby driving the connector seat 1 and the connector cover 2 to move relative to each other, so as to push the connector cover 2 out of the connector seat 1.

[0082] Further, the telescopic rod 41 includes a first rod 412 and a second rod 413, the first rod 412 and the second rod 413 are slidably sleeved, the end of the first rod 412 away from the second rod 413 is set as the above-mentioned first end, and the end of the second rod 413 away from the first rod 412 is set as the above-mentioned second end. A limiting member is arranged between the first rod 412 and the second rod 413 to limit the separation of the two through the limiting member. For example, the first rod 412 is arranged as a hollow structure with an open end, and a first limiting platform is arranged on the inner wall of the open end, the second rod 413 is slidably arranged in the first rod 412, and a second limiting platform is circumferentially arranged at one end of the second rod 413 located inside the first rod 412, and when the second rod 413 slides to the outside of the first rod 412, the first limiting platform blocks the second limiting platform to prevent the second rod 413 from completely sliding out of the first rod 412. Of course, other forms of limiting structures may also be used to prevent the second rod 413 from being separated from the first rod 412 , and the specific structural form of the limiting structure is not limited here.

[0083] Exemplarily, the telescopic driving member 42 is constructed as a spring, and the first end and the second end of the telescopic rod 41 are respectively provided with a limit protrusion 411, and the two ends of the spring are respectively abutted against the limit protrusions 411 at the first end and the second end. In this way, the spring is limited to a position sleeved on the outside of the telescopic rod 41, and the elastic force of the spring is used to drive the second end to move.

[0084] In some embodiments, the elastic member 4 further includes a guide sleeve 43, which is connected to the connector base 1 or the connector cover 2, and the telescopic rod 41 and the spring are partially limited in the guide sleeve 43, and the other part extends out of the guide sleeve 43. In this way, the guide sleeve 43 can provide limitation and guidance for the expansion and contraction of the spring, preventing the spring from being twisted when being compressed by the limiting protrusion 411.

[0085] Specifically, the guide sleeve 43 is configured to be cylindrical, the first end of the telescopic rod 41 is connected to the bottom of the guide sleeve 43, and one end of the telescopic driving member 42 abuts against the bottom of the guide sleeve 43, so that the guide sleeve 43 plays a role in limiting the telescopic driving member 42, thereby saving the need to provide a limiting protrusion 411 at the first end of the telescopic rod 41. The inner diameter of the guide sleeve 43 is slightly larger than the outer diameter of the telescopic driving member 42, so that the telescopic driving member 42 can freely extend and retract in the guide sleeve 43.

[0086] Optionally, the guide sleeve 43 is connected to the connector seat 1 or the connector cover 2 to achieve the installation of the telescopic rod 41 and the telescopic drive member 42.
