Description

Technical Field

[0001] This utility model belongs to the field of battery pack technology, and in particular relates to an overcurrent fuse protection nickel sheet and a battery pack. Background Technology

[0002] Battery pack overcurrent fuse refers to the fuse breaking the circuit by melting its internal fusible element when the current in the battery pack exceeds a set safety threshold, thereby preventing the current from continuing to flow and causing potential equipment damage or fire. During the operation of the battery pack, the continuous operation of the battery often leads to an increase in temperature, which increases the risk of overcurrent. This paper proposes a battery pack that can cool the battery. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an overcurrent fuse protection nickel sheet and battery pack, solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an overcurrent fuse protection nickel sheet and battery pack, comprising a base, vents, fan blades, and guide holes. Multiple vents are symmetrically fixedly connected to both sides of the base, and multiple fan blades are disposed within these vents, with the central axis of each fan blade parallel to the base. Multiple guide holes are arranged in a circular array on the base, and the guide holes communicate with the cavity of the base cavity. A connecting rod is also provided, with multiple arc blocks symmetrically fixedly connected to both sides of the connecting rod, and the arc blocks are attached to the battery.

[0005] Beneficial effects

[0006] This utility model provides an overcurrent fuse protection nickel sheet and battery pack, which has the following advantages compared with the prior art:

[0007] Since the batteries have been neatly arranged on the table before use, the user can bring the connecting rod close to the first row of batteries, ensuring that the symmetrically arranged arcs on it align with the batteries and apply appropriate pressure to prevent the neatly arranged batteries from scattering. This will also adhere the first row of batteries to the arcs. The user then attaches multiple rows of batteries sequentially to their corresponding connecting rods, followed by soldering nickel plates to the batteries to connect them. The user can then align the connecting rod with the square groove in the slot and press it down, causing it to be pressed into the slot. At this point, the ends of the batteries with soldered nickel plates are simultaneously inserted into the grooves, thus fixing the batteries to the base. The user then places the top plate on top of the batteries, aligning the positioning holes with the batteries. Because the diameter of the positioning holes is smaller than the batteries, the top plate can be used to... The battery is pressed firmly onto the base, ensuring it is vertically fixed and preventing tilting that could lead to poor heat dissipation. The user then places multiple nickel plates into nickel plate slots B. Since slots B connect horizontally and vertically adjacent slots, the nickel plates adhere to the slots and contact the battery. The user then solders these plates onto the battery, connecting both ends of the multiple batteries to complete the installation. During use, the user starts the motor, causing the fan blades fixed to the motor output shaft to rotate at a constant speed, generating negative pressure airflow. Because the base cavity has multiple guide holes, the airflow blows towards the battery. Simultaneously, since the battery is vertically mounted on the base, the airflow effectively cools the battery as a whole, preventing overheating and potential overcurrent melting during operation.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0014] Please see Figures 1-3 This invention provides an embodiment of an overcurrent fuse protection nickel sheet and battery pack, including a base 101, vents 201, fan blades 202, and flow guide holes 203. Multiple vents 201 are symmetrically fixedly connected to both sides of the base 101. Multiple fan blades 202 are disposed in the vents 201, and the central axis of the fan blades 202 is parallel to the base 101. Multiple flow guide holes 203 are arranged in a ring array on the base 101, and the flow guide holes 203 communicate with the cavity of the base 101.

[0015] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific base 101 described in the above embodiments. For example, the base 101 and other components are all made of plastic.

[0016] Specifically, the 101 is provided with a plurality of grooves 204, and the guide hole 203 surrounds the grooves 204. The nickel plate groove A205 is provided on the surface of the base 101, and the nickel plate groove A205 connects the plurality of grooves 204 to each other. The plurality of fan blades 202 are respectively fixedly connected to the output shaft of the motor 309, and the plurality of motors 309 are symmetrically fixedly connected to both sides of the 101.

[0017] Regarding the above examples, those skilled in the art should understand that the implementation of the above technical solutions is not limited to the specific nickel plate slots A205 and B209 described in the above embodiments. For example, the width of the nickel plate slots A205 and B209 should be slightly larger than the width of the nickel plate. The purpose of this setting is to facilitate the quick placement of the nickel plate into the nickel plate slots A205 and B209.

[0018] Specifically, a battery 206 is inserted into the groove 204, and the other end of the battery 206 is attached to the top plate 208 through a positioning hole 301. The diameter of the positioning hole 301 is smaller than the diameter of the battery 206, so that the top plate 208 can hold the battery 206.

[0019] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific groove 204 described in the above embodiments. For example, the inner wall of the groove 204 may be provided with a ring of anti-slip rubber. The purpose of this setting is to facilitate the increase of the stability of the connection between the groove 204 and the battery 206.

[0020] Specifically, the top plate 208 has multiple nickel plate slots B209, which connect adjacent positioning holes 301 in the horizontal and vertical directions. The base 101 cavity is fixedly connected with a partition plate 207 of the same height and length as the base plate 209.

[0021] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific partition 207 described in the above embodiments. For example, the partition 207 should be able to block the bottom cavity of the base 101. The purpose of this arrangement is to facilitate the uniform division of the bottom cavity of the base 101 into two sections through this arrangement, so as to avoid the fan blades 202 on both sides from affecting each other.

[0022] Specifically, the base 101 has multiple slots 302 symmetrically fixedly connected at both ends, and a connecting rod 303 is inserted into the slot 302. Multiple arc blocks 304 are symmetrically fixedly connected to both sides of the connecting rod 303.

[0023] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific arc block 304 described in the above embodiments. For example, the arc block 304 is provided with an adhesive layer. The purpose of this setting is to facilitate the adhesion of the battery 206 to the arc block 304 through the adhesive layer, so that the entire row of batteries 206 can be inserted into the base 101 in batches, thereby realizing rapid battery assembly.

[0024] Specifically, the arc block 304 is attached to the battery 206, and the arc blocks 304 provided on two adjacent connecting rods 303 can form a complete ring after docking.

[0025] Specifically, the base 101 is fixedly connected to the two sides of the sleeve 305, and the sleeve 305 is inserted into the tube 306. The other end of the tube 306 is fixedly connected to the top plate 208 to prevent the battery 206 from being laterally pressured.

[0026] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific sleeve 305 and insertion tube 306 described in the above embodiments. For example, the sleeve 305 and insertion tube 306 should be made of metal with high hardness. The purpose of this setting is to increase their load-bearing capacity through this setting, thereby avoiding deformation and squeezing of the battery 206.

[0027] Specifically, the sleeve 305 is threaded with a screw A307, which is used to abut against the insertion tube 306, and the slot 302 is threaded with a screw B308, which is used to abut against the connecting rod 303.

[0028] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific screws A307 and B308 described in the above embodiments. For example, the surfaces of screws A307 and B308 used to contact the insertion tube 306 and the connecting rod 303 can be set as relatively sharp protrusions. The purpose of this setting is to facilitate the increase of the stability of the connection.

[0029] In this embodiment of the invention, since the batteries 206 have been neatly arranged on the table before use, the user can bring the connecting rod 303 close to the first row of batteries 206, so that the multiple symmetrically arranged arc blocks 304 on it fit against the batteries 206, and apply appropriate pressure to ensure that the neatly arranged batteries 206 do not fall apart. At the same time, the first row of batteries 206 can be adhered to the arc blocks 304. Then, the user can attach multiple rows of batteries 206 to the corresponding connecting rods 303 in sequence, and then weld the nickel sheets to the batteries 206. This connects multiple batteries 206 together. The user then aligns the connecting rod 303 with the square groove in the slot 302 and presses it down, causing it to be pressed into the slot 302. Simultaneously, the ends of the batteries 206 with soldered nickel sheets are inserted into the grooves 204, thus fixing the batteries 206 onto the base 101. The user then places the top plate 208 on the batteries 206, aligning the positioning hole 301 with the battery 206. Since the diameter of the positioning hole 301 is smaller than that of the battery... Therefore, the top plate 208 can press multiple batteries 206 onto the base 101, ensuring that the batteries 206 are vertically fixed on the base 101 and preventing them from tilting, which would lead to poor heat dissipation. Then, the user should place multiple nickel plates into the nickel plate slots B209. Since the nickel plate slots B209 connect adjacent nickel plate slots B209 horizontally and vertically, the nickel plates will adhere to the nickel plate slots B209 and contact the batteries 206. The user then solders them onto the batteries 206, thus securing the multiple batteries 206 together. All ends are interconnected to complete the installation of battery 206. During use, the user should start motor 309, so that the fan blade 202 fixedly connected to the output shaft of motor 309 rotates at a constant speed, thereby generating negative pressure airflow. At this time, since the cavity of base 101 is only connected to multiple guide holes 203, the airflow blows from multiple guide holes 203 to battery 206. At the same time, since battery 206 is vertically set on base 101, the airflow can cool it as a whole, thereby avoiding the battery from overheating and melting due to overcurrent during operation.

[0030] Meanwhile, when the user places the top plate 208 on the battery 206, the multiple insertion tubes 306 fixed on both sides can be inserted into the sleeve 305 simultaneously. Then the user tightens the screw A307 to fix the insertion tubes 306 in the sleeve 305, thereby providing lateral pressure protection for the battery 206.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, 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 process, method, article, or apparatus.

[0032] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0033] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0034] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0035] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
