Description

Technical Field

[0001] This invention relates to the field of aluminum alloy forming and application technology, and in particular to an aluminum alloy profile and its application as a lithium battery tray. Background Technology

[0002] A lithium battery tray is a tray structure used to hold multiple lithium batteries, making it easier to store them. Most existing lithium battery trays are made of polymer plastic or metal plate. The lithium battery tray has multiple slots for holding lithium batteries, with one battery placed in each slot. This facilitates the movement of multiple lithium batteries, drying multiple lithium batteries in a drying chamber, or adding electrolyte to multiple lithium batteries.

[0003] Existing lithium battery trays are made in one piece. Due to the structure made of polymer plastic, they have poor air permeability and are prone to deformation after long-term use. On the other hand, the current metal plates are directly cast profiles or stamped to form fixing grooves for fixing batteries. The battery part located in the fixing groove has poor air permeability, which makes it difficult for lithium batteries to dry. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes an aluminum alloy profile and its application in lithium battery trays.

[0005] The present invention proposes an aluminum alloy profile, comprising a profile body, wherein the profile body has a receiving through hole along its length direction, the receiving through hole has at least three inner sides, and an adjustment channel is formed between any two adjacent inner sides, the adjustment channel being distributed along the length direction of the profile body;

[0006] A first vent hole is formed on the first sidewall of the profile body, and a second vent hole is formed on the second sidewall of the profile body. Both the first vent hole and the second vent hole are connected to the receiving through hole, and the first sidewall and the second sidewall are opposite to each other.

[0007] The first and second vents provide good heat dissipation, and the through-holes allow for the clamping of components that match the through-holes. Additionally, if the component to be clamped is smaller than the through-hole, an adjusting block can be installed in the adjusting channel to secure the component within the through-hole and prevent it from shaking.

[0008] To facilitate the placement of multiple aluminum alloy profiles, based on the above technical solution, as a further optimization of the present invention, the side of the first sidewall away from the receiving through hole has a locking protrusion, the locking protrusion is arranged along the length direction of the profile body, the first vent hole is opened on the locking protrusion, and the side of the second sidewall away from the receiving through hole has a locking groove, the locking protrusion and the locking groove are matched, the locking protrusion of one aluminum alloy profile matches the locking groove of another aluminum alloy profile, thereby realizing the fixation of two aluminum alloy profiles.

[0009] To facilitate the fixing of the cylindrical battery, as a further optimization of the present invention based on any of the above technical solutions, the inner surface is an arc surface, and the central axis of the arc surface coincides with the central line of the profile body, further increasing the stability of the connection.

[0010] To further enhance the heat dissipation effect, based on any of the above technical solutions, as a further optimization of the present invention, a heat dissipation channel is also included. The heat dissipation channel is opened along the length direction of the profile body, and the adjustment channel connects the heat dissipation channel and the receiving through hole.

[0011] Based on any of the above technical solutions, as a further optimization of the present invention, the heat dissipation channel has a partition plate, and the partition plate is opposite to the adjustment channel.

[0012] Based on any of the above technical solutions, as a further optimization of the present invention, a fixing groove is provided on the partition plate, the fixing groove being opposite to the adjustment channel and communicating with the heat dissipation channel.

[0013] A lithium battery tray includes a base plate on which a plurality of fasteners are fixed. The fasteners are made of aluminum alloy profiles as described in any of the above claims, and each fastener includes at least one set of first vent holes and at least one set of second vent holes. The receiving through holes are used to receive lithium batteries, and the first vent hole of one of any two adjacent fasteners communicates with the second vent hole of the other fastener.

[0014] Based on any of the above technical solutions, as a further optimization of the present invention, the first vent hole and the second vent hole are coaxial, ensuring that the first vent hole and the second vent hole of the two fasteners are connected.

[0015] Based on any of the above technical solutions, as a further optimized solution of the present invention, it also includes an outer frame, which is fixed on the base plate, and a receiving groove is formed between the outer frame and the base plate. The fastener is located in the receiving groove, and the horizontal width of the receiving groove is an integer multiple of the width of the aluminum alloy profile, and the vertical width of the receiving groove is an integer multiple of the vertical width of the aluminum alloy profile.

[0016] Based on any of the above technical solutions, as a further optimization of the present invention, the outer frame has a ventilation channel, and the outer frame has a first through hole and a second through hole, both of which are connected to the ventilation channel. The first ventilation hole or the second ventilation hole of the fastener that contacts the outer frame is connected to the first through hole.

[0017] In this invention, the proposed aluminum alloy profile and its application in a lithium battery tray include a base plate and fasteners fixed on the base plate. The fasteners are formed by transversely cutting the aluminum alloy profile. Each fastener has a receiving through hole that accommodates a lithium battery. The structure is simple. The arrangement of the first and second vent holes increases the connectivity of the receiving through holes on the lithium battery tray, which facilitates heat dissipation.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] Example 1

[0031] like Figure 1 As shown, an aluminum alloy profile includes a profile body, which is rectangular in shape and has a square cross-section along its length. The profile body has a receiving through hole 1 along its length, and the receiving through hole 1 has four inner sides. An adjustment channel 2 is formed between any two adjacent inner sides. The adjustment channel 2 is distributed along the length of the profile body. The four sides of the receiving through hole 1 are arc surfaces that match the outer wall of a cylindrical lithium battery. The central axis of the arc surface coincides with the centerline of the profile body.

[0032] A first vent hole 4 is opened on the first side wall of the profile body, and a second vent hole 5 is opened on the second side wall of the profile body. Both the first vent hole 4 and the second vent hole 5 are connected to the receiving through hole 1. The first side wall and the second side wall are opposite to each other. Multiple first vent holes 4 and multiple second vent holes 5 are opened, and the multiple first vent holes 4 and multiple second vent holes 5 are evenly distributed along the length direction of the profile body.

[0033] The side of the first sidewall away from the receiving through hole 1 has a locking protrusion 6, which is arranged along the length of the profile body. The first vent hole 4 is opened on the locking protrusion 6. The side of the second sidewall away from the receiving through hole 1 has a locking groove 7. The locking protrusion 6 matches the locking groove 7. The locking protrusion 6 of one aluminum alloy profile matches the locking groove 7 of another aluminum alloy profile, thereby realizing the fixation of the two aluminum alloy profiles.

[0034] The profile body also has heat dissipation channels 8, which are opened along the length of the profile body. There are four heat dissipation channels 8, which are distributed at the four corners of the profile body. One heat dissipation channel 8 is connected to an adjustment channel 2.

[0035] A partition plate 9 is provided inside a heat dissipation channel 8 along the length of the profile body. The partition plate 9 is fixed at the corner of the inner wall of the heat dissipation channel 8. The partition plate 9 is opposite to the adjustment channel 2. A fixing groove 90 is opened on the partition plate. The fixing groove 90 is opposite to the adjustment channel 2 and communicates with the heat dissipation channel 8.

[0036] like Figure 2-3 The lithium battery tray shown includes a base plate 10, a fastener 11, and an outer frame 12, wherein:

[0037] The outer frame 12 is fixed to the base plate 10 by welding or locking parts. The outer frame 12 and the base plate 10 form a receiving groove. Multiple fasteners 11 are provided, and the multiple fasteners 11 are distributed in multiple rows and columns in the receiving groove. Any two adjacent fasteners 11 are in contact with each other, and the outermost fastener 11 is in contact with the inner wall of the receiving groove.

[0038] The fastener 11 is formed by transverse cutting of the aforementioned aluminum alloy profile. Each fastener 11 has a receiving through hole 1, a first vent hole 4, a second vent hole 5, a heat dissipation channel 8, and a partition plate 9. Each fastener 11 also has a fastening protrusion 6 and a fastening groove 7. The fastening protrusion 6 and the fastening groove 7 of two adjacent fasteners 11 in the same row are matched. The first vent hole 4 and the second vent hole 5 of any two adjacent fasteners 11 are connected. The lithium battery is placed on the receiving through hole 1 of the fastener 11, and the outer wall of the lithium battery is in contact with the inner wall of the receiving through hole 1.

[0039] To further enhance stability, a vertical protrusion 123 is provided on one side wall of the receiving groove. The protrusion 123 matches the locking groove 7 of the fastener 11 that contacts the side wall. A locking groove 124 is vertically opened on the other side wall of the receiving groove. The locking groove 124 is opposite to the protrusion 123 and is used to match the locking protrusion 6 of the fastener 11 that contacts the side wall, further enhancing stability.

[0040] like Figure 3 As shown, the outer frame 12 has a ventilation channel 120, and the outer frame 12 has a first through hole 121 and a second through hole 122. The first through hole 121 and the second through hole 122 are both connected to the ventilation channel 120. The first ventilation hole 4 or the second ventilation hole 5 of the fastener 11 located on the side of the receiving groove is connected to the first through hole 121, thereby facilitating the heat dissipation of the lithium battery located in the receiving through hole 1.

[0041] Since the receiving through holes 1 for accommodating the battery are formed on the base plate 10 by fasteners 11, and multiple fasteners 11 are spliced ​​together to form a matrix of receiving through holes 1, the user can increase or decrease the number of fasteners 11 according to actual needs.

[0042] Furthermore, due to the setting of the adjustment channel 2, when the outer diameter of the lithium battery is equal to the diameter of the receiving through hole 1, the lithium battery can be directly placed in the receiving through hole 1. When the lithium battery is dried, the setting of the first vent hole 4, the second vent hole 5, the first through hole 121, the second through hole 122, the heat dissipation channel 8, the adjustment channel 2, and the venting channel 120 facilitates heat dissipation of the lithium battery. When the lithium battery is injected with electrolyte, a test paper can be placed in the adjustment channel 2 so that the test paper contacts the outer wall of the lithium battery located in the receiving through hole 1, thereby determining whether there is electrolyte on the outer wall of the lithium battery during the electrolyte injection process. When the high voltage of the lithium battery is leaking, the test paper can also be stuck in the adjustment channel 2 and made to contact the outer wall of the lithium battery located in the receiving through hole 1, thereby detecting whether there is leakage on the outer wall of the lithium battery. Specifically, the test paper can be stuck in the fixing groove 90.

[0043] During processing, the aluminum alloy profile is processed first, and then the aluminum alloy profile is cut horizontally. The cut section is perpendicular to the length direction of the aluminum alloy profile, which further increases the processing accuracy and processing efficiency.

[0044] Example 2

[0045] like Figure 4-5 The lithium battery tray shown in this embodiment differs from the previous embodiment in that it also includes adjustment blocks 3. The number of adjustment blocks 3 is the same as the number of adjustment channels 2. There are four adjustment blocks 3. Each adjustment block 3 is fixed in one adjustment channel 2. Preferably, the adjustment block 3 also has an extension strip 30, which is engaged with the fixing groove 90. The side of the adjustment block 3 away from the heat dissipation channel 8 is the adjustment clamping surface. An adjustment heat dissipation channel 13 is formed between any two adjacent adjustment clamping surfaces. One adjustment heat dissipation channel is opposite to and connected to the first vent 5, and another adjustment heat dissipation channel 13 is opposite to and connected to the second vent 6. The side wall of the adjustment block 3 has a groove 31. The adjustment heat dissipation channel 13 is connected to the heat dissipation channel 8 through the groove 31. The adjustment clamping surfaces of the four adjustment blocks 3 form an adjustment receiving through hole 14. The adjustment receiving through hole 14 is used to accommodate lithium batteries with smaller outer diameter walls than the receiving through hole 1, thereby realizing the accommodation of lithium batteries with different outer diameters and increasing the flexibility of the tray.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
