Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery device and electrical equipment. Background Technology

[0002] With the development of new energy technologies, batteries are being used more and more widely. Batteries are installed in electrical equipment to provide power. For example, batteries are used to power vehicles, requiring them to be installed in the vehicle. To facilitate quick positioning and installation, positioning structures, such as locating pins, are typically incorporated into the battery.

[0003] However, current positioning structures have certain installation requirements for the battery housing structure or the structure of the positioning pin itself, which limits the installation and use of the positioning structure. Utility Model Content

[0004] Therefore, it is necessary to provide a battery device and electrical equipment to address the problem that the current positioning structure has certain installation requirements on the battery housing structure or the positioning pin itself, which restricts the installation and use of the positioning structure.

[0005] In a first aspect, this application provides a battery device, including a housing, a fixing member, and a positioning pin. The housing has a first mounting hole. The fixing member is fixed in the first mounting hole and has a second mounting hole. The positioning pin includes an action section and a connecting section. The connecting section is accommodated in the second mounting hole and fixedly connected to the fixing member. One end of the action section connected to the connecting section is accommodated in the second mounting hole, and the other end of the action section opposite to the connecting section protrudes out of the second mounting hole and is used to connect with an external structure.

[0006] Therefore, the positioning pin is fixedly installed to the housing through the fastener, which not only allows the positioning pin to be adapted to housings of different structures through the fastener, but also eliminates the need for the positioning pin to be directly connected to the housing, enabling the installation of positioning pins of different diameters on the housing.

[0007] In some embodiments, a first thread is provided in the second mounting hole, and a second thread that mates with the first thread is provided on the outer surface of the connecting section.

[0008] By using the above structure to screw the connecting section and the fixing part together, a quick connection between the positioning pin and the fixing part can be achieved, so that the positioning pin is more stably set in the second mounting hole.

[0009] In some embodiments, the active section is provided with a constant diameter along the axial direction of the locating pin.

[0010] Therefore, the locating pin itself is not directly connected to the housing, but is fixedly connected to the housing through a fastener, so that the diameter of the active section can always be consistent inside and outside the second mounting hole, that is, it can be adapted to locating pins with smaller diameters.

[0011] In some embodiments, the connecting segments are of equal diameter along the axial direction of the locating pin; wherein the diameter of the active segment is equal to the diameter of the connecting segment; or the diameter of the active segment is larger than the diameter of the connecting segment. When the diameter of the active segment is equal to the diameter of the connecting segment, the diameter of the locating pin can be minimized, that is, it can accommodate locating pins with smaller diameters. When the diameter of the active segment is slightly larger than the diameter of the connecting segment, the active segment can further improve the overall support stability of the locating pin.

[0012] In some embodiments, the fastener is welded to the first mounting hole; and / or, the fastener is riveted to the first mounting hole; and / or, the fastener is screwed to the first mounting hole.

[0013] The above structure enables quick and stable installation of the fastener within the first mounting hole.

[0014] In some embodiments, in the opening direction of the first mounting hole, at least one end face of the fastener is flush with the surface of the housing.

[0015] The above structure allows the battery device to be used in electrical equipment with strict envelope structure limitations, and makes assembly easier.

[0016] In some embodiments, the locating pin further includes an anti-rotation section connected to one end of the actuating section away from the connecting section, and at least a portion of the outer peripheral surface of the anti-rotation section forms an anti-rotation plane, which is used to cooperate with the wall of the external locating hole to restrict the rotation of the locating pin.

[0017] With the above structure, when the positioning pin is inserted into the positioning hole, the anti-rotation plane can restrict the rotation of the positioning pin, thereby making the fit between the battery device and the electrical equipment more stable.

[0018] In some embodiments, the locating pin further includes a guide section connected to one end of the anti-rotation section away from the action section, and the diameter of the guide section gradually decreases from the end closer to the anti-rotation section to the end farther away from the anti-rotation section.

[0019] When the locating pin is inserted into the locating hole, the guide section enters the locating hole first, so that the locating pin can be inserted into the locating hole more smoothly under the guidance of the guide section.

[0020] In some embodiments, the enclosure includes interconnected enclosure walls and a mounting beam, a first mounting hole is provided in the mounting beam, and an active section is used to connect to the electrical main body of the electrical equipment.

[0021] Secondly, this application also provides an electrical device, including an electrical main body and a battery device as described above. The battery device is used to provide electrical energy to the electrical main body, and a positioning hole is provided on the electrical main body, with a positioning pin for insertion and engagement with the positioning hole.

[0022] The aforementioned battery device and electrical equipment first install the fixing component in the first mounting hole of the housing, and then fix the positioning pin in the second mounting hole of the fixing component. The fixing component is used to fix the positioning pin on the housing. In this way, the positioning pin can not only be adapted to housings with different structures, such as thin-walled housings, through the fixing component, but also the positioning pin does not need to be directly connected to the housing, enabling the installation of positioning pins of different diameters on the housing.

Detailed Implementation

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in other fields. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0040] A battery, also known as a battery pack, typically consists of a housing and one or more individual battery cells housed within it. Battery packs are widely used in various electrical devices, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft (e.g., aircraft, rockets, space shuttles, and spaceships). When a battery pack is used in a device, it needs to be stably installed. Taking a vehicle as an example, to facilitate quick and easy installation and prevent displacement during vehicle movement, a positioning structure is required on the housing. This structure aligns with positioning holes and other features on the vehicle, allowing for quick and stable installation.

[0041] Current positioning structures typically involve setting a protruding positioning pin on the housing and opening positioning holes at corresponding positions on electrical equipment such as vehicles. Inserting the positioning pin into the positioning holes allows for stable installation of the battery device on the electrical equipment.

[0042] However, the current positioning structure has certain installation requirements for the battery housing or the positioning pin itself. For example, different battery housings have different structures, including some thin-walled housings, that is, the housing walls are thin, which is not conducive to the direct installation of the positioning pins. Additional structures are needed to fix the positioning pins to the housing.

[0043] For example, the positioning holes on electrical equipment from different manufacturers are not the same size, meaning that different electrical equipment requires positioning pins of different diameters. However, current positioning structures are generally only suitable for larger diameter positioning pins; that is, they can only install larger diameter positioning pins on the enclosure, but cannot install smaller diameter positioning pins. This limits the installation and application scenarios of the positioning structure, failing to meet the needs of different electrical equipment.

[0044] Based on the above considerations, in order to address the problem that current positioning structures have certain installation requirements on the battery housing structure or the structure of the positioning pin itself, thus limiting the installation and use of the positioning structure, one or more embodiments of this application provide a battery device. First, a fixing member is installed in a first mounting hole in the housing, and then the positioning pin is fixed in a second mounting hole in the fixing member. The fixing member secures the positioning pin to the housing. In this way, the positioning pin can not only adapt to housings with different structures, such as thin-walled housings, through the fixing member, but also does not need to be directly connected to the housing, enabling the installation of positioning pins of different diameters on the housing.

[0045] It should be noted that the battery apparatus mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0046] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells. As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form a single module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0047] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.

[0048] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0049] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0050] See Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a battery device 100, including a housing 10, a fixing member 20, and a positioning pin 30. The housing 10 has a first mounting hole 11, the fixing member 20 is fixed in the first mounting hole 11, and the fixing member 20 has a second mounting hole 21. The positioning pin 30 includes an action section 31 and a connecting section 32. The connecting section 32 is accommodated in the second mounting hole 21 and fixedly connected to the fixing member 20. One end of the action section 31 connected to the connecting section 32 is accommodated in the second mounting hole 21, and the other end of the action section 31 opposite to the connecting section 32 protrudes out of the second mounting hole 21 and is used for connection with an external structure.

[0051] It should be noted that the battery device 100 may also include one or more battery cells 40. The housing 10 refers to a structure that can provide housing space for the battery cells 40 and provide a certain degree of protection for the battery cells 40. The housing 10 may include interconnected housing walls and mounting beams. A first mounting hole 11 is provided on the housing 10. Specifically, the first mounting hole 11 may be provided on the mounting beam of the housing 10. The first mounting hole 11 may be a through hole or a blind hole provided on the mounting beam.

[0052] The fastener 20 refers to a structure that can fix the housing 10 and the positioning pin 30 together. The size and shape of the fastener 20 are adapted to the first mounting hole 11 so as to fix the fastener 20 in the first mounting hole 11. The fastener 20 is provided with a second mounting hole 21. When the fastener 20 is provided in the first mounting hole 11, the second mounting hole 21 and the first mounting hole 11 are in the same direction, that is, the axial direction a of the first mounting hole 11 and the second mounting hole 21 are parallel to each other.

[0053] The positioning pin 30 refers to a structure that is fixed to the housing 10 by the fastener 20 and can be inserted into the external positioning hole on the electrical equipment to achieve quick and stable installation of the battery device 100 on the electrical equipment. Positioning holes are provided at corresponding positions on the electrical equipment, and the shape and size of the positioning holes match those of the positioning pin 30 to ensure better insertion and engagement.

[0054] Specifically, the positioning pin 30 includes an action section 31 and a connecting section 32. The action section 31 and the connecting section 32 are connected to each other. The connecting section 32 of the positioning pin 30 is inserted into the second mounting hole 21, and the connecting section 32 can be fixedly connected to the fastener 20, thereby realizing the fixed installation of the positioning pin 30.

[0055] One end of the functional segment 31 connected to the connecting segment 32 is also accommodated in the second mounting hole 21, while the other end extends in a direction away from the connecting segment 32 and protrudes out of the second mounting hole 21. In this way, a portion of the functional segment 31 protruding out of the second mounting hole 21 can be inserted into the positioning hole on the electrical device, thereby achieving the positioning of the battery device 100 on the electrical device.

[0056] Thus, the positioning pin 30 is fixedly installed to the housing 10 through the fastener 20, so that the positioning pin 30 can not only be adapted to housings 10 with different structures through the fastener 20, but also the positioning pin 30 does not need to be directly connected to the housing 10, enabling the installation of positioning pins 30 with different diameters on the housing 10.

[0057] Specifically, for current enclosure structures, the wall thickness of some thin-walled enclosures can reach 1.5mm. These thin-walled enclosures have a smaller volume, which is more conducive to improving the volumetric energy density of the battery device 100. The positioning pin 30 provided in this application can be applied to the aforementioned thin-walled enclosure with the aid of the fixing member 20, thus increasing the applicability of the positioning pin 30.

[0058] Furthermore, since the locating pin 30 does not need to be directly connected to the housing 10, it can be used for locating pins with smaller diameters, specifically locating pins with a diameter of 3mm, so that small-diameter locating pins can be stably connected to the housing.

[0059] In some embodiments, a first thread is provided in the second mounting hole 21, and a second thread that mates with the first thread is provided on the outer surface of the connecting section 32.

[0060] The connecting segment 32 and the fixing member 20 can be connected by threads. An internal thread (first thread) is provided in the second mounting hole 21, and an external thread (second thread) that mates with the internal thread is provided on the outer surface of the connecting segment 32. The connecting segment 32 is inserted into the second mounting hole 21, and the locating pin 30 is rotated to screw the second thread of the connecting segment 32 into the first thread in the second mounting hole 21, thereby achieving the fixed installation of the locating pin 30 within the second mounting hole 21.

[0061] Specifically, a first thread is provided in the second mounting hole 21. This can be achieved by directly opening the first thread on the hole wall of the second mounting hole 21 or by embedding a wire thread sleeve in the second mounting hole 21. Both methods can achieve threaded connection with the connecting section 32.

[0062] By screwing the connecting section 32 and the fixing member 20 together with the above structure, the positioning pin 30 and the fixing member 20 can be quickly connected, so that the positioning pin 30 is more stably set in the second mounting hole 21.

[0063] In some other embodiments, the connecting segment 32 and the fixing member 20 can also be connected in other ways. For example, a buckle can be provided on the outer surface of the connecting segment 32, and a groove can be provided on the wall of the second mounting hole 21 to achieve engagement between the two, so that the positioning pin 30 can be fixedly installed in the second mounting hole 21. Therefore, a fixed connection between the connecting segment 32 and the fixing member 20 can also be achieved by using a buckle connection or other connection methods, which will not be elaborated here.

[0064] In some embodiments, the active segment 31 is provided with a constant diameter along the axial direction a of the locating pin 30.

[0065] Specifically, when the positioning pin 30 is inserted into the second mounting hole 21, the axial direction a of the positioning pin 30 is parallel to the axial direction of the second mounting hole 21, which is the extension direction of the positioning pin 30.

[0066] Along the axial direction a of the locating pin 30, the diameter of the actuating segment 31 is equal. That is, the actuating segment 31 is a cylindrical structure with a constant diameter, and the diameter of the portion of the actuating segment 31 located inside the second mounting hole 21 is equal to the diameter of the portion located outside the second mounting hole 21. Therefore, the outer circumferential surface of the portion of the actuating segment 31 located inside the second mounting hole 21 is always in contact with the hole wall of the second mounting hole 21, and the actuating segment 31 does not contact the housing 10.

[0067] Therefore, the positioning pin 30 is not directly connected to the housing 10, but is fixedly connected to the housing 10 through the fastener 20, so that the diameter of the active section 31 inside and outside the second mounting hole 21 can always be consistent, that is, it can be adapted to positioning pins 30 with smaller diameters.

[0068] In some embodiments, the connecting section 32 is provided with a constant diameter along the axial direction of the locating pin 30. Specifically, the diameter of the functional section 31 is equal to the diameter of the connecting section 32, or the diameter of the functional section 31 is greater than the diameter of the connecting section 32.

[0069] Specifically, since the outer circumferential surface of the connecting section 32 is provided with a second thread, the diameter of the connecting section 32 refers to the maximum diameter of the connecting section 32, that is, the diameter of the protruding position of the second thread.

[0070] The diameter of the active segment 31 can be set to be equal to the diameter of the connecting segment 32, or it can be set to be larger than the diameter of the connecting segment 32. Where the diameter of the active segment 31 is larger than the diameter of the connecting segment 32, it means that the diameter of the active segment 31 is slightly larger than the diameter of the connecting segment 32.

[0071] When the diameter of the actuating segment 31 is equal to the diameter of the connecting segment 32, the diameter of the positioning pin 30 can be minimized, that is, it can accommodate positioning pins 30 with smaller diameters. When the diameter of the actuating segment 31 is slightly larger than the diameter of the connecting segment 32, the actuating segment 31 can further improve the overall support stability of the positioning pin 30.

[0072] like Figures 2-7 As shown, in some embodiments, the fastener 20 is welded to the first mounting hole 11. And / or, the fastener 20 is riveted to the first mounting hole 11. And / or, the fastener 20 is screwed to the first mounting hole 11.

[0073] Specifically, the fastener 20 can be fixed in the first mounting hole 11 by welding, by welding the outer surface of the fastener 20 to the hole wall of the first mounting hole 11, thereby fixing the fastener 20 in the first mounting hole 11.

[0074] The fastener 20 can also be fixed in the first mounting hole 11 by riveting or screwing, that is, the fastener 20 and the housing 10 are fixedly connected by rivets or screws.

[0075] With the above structure, the fastener 20 can be installed quickly and stably in the first mounting hole 11.

[0076] In some embodiments, in the opening direction of the first mounting hole 11, at least one end face of the fastener 20 is flush with the surface of the housing 10.

[0077] Specifically, when the fastener 20 is disposed in the first mounting hole 11, the fastener 20 has two end faces, an upper and a lower one. The upper end face of the fastener 20 can be flush with the upper surface of the housing 10, or the lower end face of the fastener 20 can be flush with the lower surface of the housing 10. Alternatively, the upper and lower end faces of the fastener 20 can be flush with the upper and lower surfaces of the housing 10, respectively.

[0078] When the fastener 20 is fixed in the first mounting hole 11 by welding, the upper and lower surfaces of the housing 10 and the welding position of the fastener 20 can be ground flat, so that the end face of the fastener 20 is flush with the housing 10.

[0079] The above structure makes the battery device 100 suitable for electrical equipment with strict envelope structure restrictions and makes it easier to assemble.

[0080] In some embodiments, the positioning pin 30 further includes an anti-rotation section 33, which is connected to one end of the action section 31 away from the connecting section 32, and at least a portion of the outer peripheral surface of the anti-rotation section 33 is formed with an anti-rotation plane 34, which is used to cooperate with the wall of the external positioning hole to restrict the rotation of the positioning pin 30.

[0081] Specifically, the actuating segment 31 extends toward the side opposite to the connecting segment 32 to form an anti-rotation segment 33, wherein the outer peripheral surface of the anti-rotation segment 33 is cut to form an anti-rotation plane 34. At the same time, a plane that mates with the anti-rotation plane 34 is provided on the wall of the positioning hole provided in the electrical equipment. When the anti-rotation segment 33 is inserted into the positioning hole, the anti-rotation plane 34 can fit against the plane on the wall of the positioning hole, thereby realizing the anti-rotation fit between the positioning pin 30 and the positioning hole.

[0082] With the above structure, when the positioning pin 30 is inserted into the positioning hole, the anti-rotation plane 34 can restrict the rotation of the positioning pin 30, thereby making the cooperation between the battery device 100 and the electrical equipment more stable.

[0083] like Figure 2 and Figure 8 As shown, in some embodiments, the positioning pin 30 further includes a guide section 35, which is connected to the end of the anti-rotation section 33 away from the action section 31. The diameter of the guide section 35 gradually decreases from the end closer to the anti-rotation section 33 to the end farther away from the anti-rotation section 33.

[0084] Specifically, the guide section 35 is located at the end of the positioning pin 30. When the positioning pin 30 is inserted into the positioning hole, the guide section 35 enters the positioning hole first, so that the positioning pin 30 can be inserted into the positioning hole more smoothly under the guidance of the guide section 35.

[0085] Furthermore, the outer peripheral surface of the guide section 35 is formed into a conical surface. When the positioning pin 30 is inserted into the positioning hole, the guide section 35 can play a good guiding role, so that the positioning pin 30 can be inserted into the positioning hole more smoothly.

[0086] like Figure 9 As shown, in some embodiments, the housing 10 includes a housing wall 12 and a mounting beam 13 connected to each other, a first mounting hole 11 is provided on the mounting beam 13, and the working section 31 is used to connect to the electrical main body of the electrical equipment.

[0087] Based on the same concept as the battery device 100 described above, this application also provides an electrical device, including an electrical user body and the battery device 100 as described above, wherein the battery device 100 is used to provide electrical energy to the electrical user body.

[0088] In some embodiments, a positioning hole is provided on the electrical main body, and the positioning pin 30 is used to engage with the positioning hole.

[0089] According to one or more embodiments, when this application is used, the fastener 20 is first placed in the first mounting hole 11 of the housing 10. The fastener 20 can be fixed in the first mounting hole 11 by welding or riveting.

[0090] Furthermore, the connecting section 32 of the positioning pin 30 is inserted into the second mounting hole 21 on the fixing member 20, so that the second thread of the connecting section 32 and the first thread in the second mounting hole 21 are screwed together, thereby realizing the fixed installation of the positioning pin 30 in the second mounting hole 21.

[0091] At this time, the functional section 31, the anti-rotation section 33, and the guide section 35 of the positioning pin 30 are all located outside the second mounting hole 21. During the process of installing the battery device 100 into the electrical appliance, the positioning pin 30 located outside the second mounting hole 21 is inserted into the positioning hole of the electrical appliance. Among them, the guide section 35 is inserted into the positioning hole first and plays a guiding role, so that the positioning pin 30 can be inserted into the positioning hole more smoothly.

[0092] Then, the anti-rotation plane 34 of the anti-rotation section 33 fits into the plane on the wall of the positioning hole, thereby preventing the positioning pin 30 from rotating within the positioning hole and making the positioning pin 30 more stably positioned within the positioning hole. In this way, the battery device 100 can be stably installed on the electrical equipment.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
