Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to cable fixing devices and integrated energy storage devices. Background Technology

[0002] In today's era, with the continuous progress and vigorous development of society, the intelligentization of many fields such as warehousing, home, and transportation is particularly noteworthy. Portable consumer electronics are showing an increasingly diversified trend, from the initial smartphones and tablets to today's new energy vehicles, smartwatches, and smart headphones. In the application of these electronic products, the battery, as the energy output terminal, undertakes the crucial task of providing a stable power supply to the devices. The cables inside the battery become an indispensable component connecting the various components within the battery compartment.

[0003] For integrated energy storage systems, the PCS (Power Conversion System) controls the charging and discharging process of the battery, performing AC-DC conversion, and can directly supply power to AC loads in the absence of a power grid. Isolating the PCS compartment and the battery compartment is a crucial part of energy storage system design. When cables pass between the PCS and battery compartments, appropriate cable routing and securing structures are required. In some technologies, these cable routing and securing structures are not tight enough, resulting in gaps. During battery thermal runaway, large amounts of high-temperature fumes are generated, which may contain corrosive gases and particulate matter. If these fumes enter the PCS compartment through these gaps, they can corrode or contaminate sensitive electronic components, leading to equipment failure, electrical short circuits, or even more serious accidents such as fires. Utility Model Content

[0004] Therefore, it is necessary to provide a cable fixing device and an integrated energy storage unit that provides stable cable fixing and strong sealing to address the above-mentioned technical problems.

[0010] In one embodiment, the first flexible member includes a protrusion that protrudes from the surface of the wire groove.

[0011] In one embodiment, the inner surface of the wire guide groove is arc-shaped, the center of the arc-shaped inner surface is inside the wire guide groove, and the protrusion is arranged circumferentially along the surface of the wire guide groove.

[0012] In one embodiment, the base includes a wire threading section, which has a bottom wall and a side wall forming the receiving groove. The bottom wall is disposed opposite to the groove opening, and the side wall has a wire passing outlet communicating with the wire passing groove.

[0013] In one embodiment, the first flexible member includes a protrusion protruding from the surface of the wire guide groove, and the edge of the wire guide outlet is lower than the top of the protrusion on the surface of the wire guide groove.

[0014] In one embodiment, the base further includes a cable retainer located at the cable outlet, the cable retainer being used to restrict the position of the cable accommodated in the cable channel.

[0015] In one embodiment, the cable clip includes a clip arm with a limiting outlet formed on the clip arm. The limiting outlet is flush with the upper edge of the base, and the size of the limiting outlet is smaller than the minimum size of the cable.

[0016] In one embodiment, the base includes a support portion whose width increases in the direction away from the cover, and / or the width of the threading portion increases in the direction away from the cover.

[0017] In one embodiment, the fixing device further includes a second flexible member disposed on one side of the cover facing the base. After the cover is connected to the base, the second flexible member can be deformed under force.

[0018] In one embodiment, the surface of the second flexible member is planar, or the surface of the second flexible member has at least one arcuate groove, and / or the second flexible member is made of silicone or rubber.

[0023] The aforementioned cable fixing device and energy storage unit, by incorporating a first flexible component, deforms within a receiving groove when the cover is pressed against the base. The cable groove adaptively adjusts according to the cable diameter, deforming to fit snugly against the cable's periphery, forming a continuous contact surface that wraps around the cable's circumference. The cable groove corresponds to the cable, securing it more stably while maintaining cable stability and preventing damage through elastic contact. The cover is snapped onto the base, facilitating cable installation and removal. The cable fixing device, located on the compartment wall of the energy storage unit, can fix the cable at a specific position on the compartment wall and seal it along the cable's outer circumference, creating a gapless connection to isolate the space on either side of the cable. When installed inside the battery, between the battery compartment and the power compartment, the cable fixing device secures and seals the cables passing through them, preventing the large amounts of high-temperature fumes generated during battery thermal runaway from entering the power compartment, avoiding corrosion or contamination of sensitive electronic components, and preventing more serious accidents such as equipment failure, electrical short circuits, and fires.

[0036] See Figure 1-4 , Figure 1-4 The diagram shows a structural schematic of a fixing device 100 in one embodiment of this application. The fixing device 100 provided in one embodiment of this application is located at the partition wall 10 between the battery compartment 1 and the power compartment 2 (which contains a PCS) of the integrated energy storage device, in order to fix the cable passing through the battery compartment 1 and the power compartment 2. The fixing device 100 can also be used in other equipment with high sealing requirements.

[0037] The fixing device 100 includes a base 110, a cover 120, and a first flexible member 130. The base 110 is disposed on the compartment wall 10. The base 110 and / or the cover 120 are provided with a receiving groove 1111, which has an open opening. The cover 120 is adapted to fasten the base 110, and after the cover 120 is connected to the base 110, the cover 120 is closed. The first flexible member 130 is disposed within the receiving groove 1111. The first flexible member 130 is provided with at least one cable passage groove 131 for placing cables. After the cover 120 is connected to the base 110, the first flexible member 130 can deform under force.

[0038] It should be noted that the receiving groove 1111 can be set on the base 110, or on the cover 120, or both.

[0039] An embodiment of this application also provides an integrated energy storage unit, which includes a compartment wall 10 and a sealing device 100. The compartment wall 10 is used to separate a battery compartment 1 and a power compartment 2. The fixing device 100 is disposed on the compartment wall 10, and the base 110 is disposed on the compartment wall 10.

[0040] The battery compartment is mainly used to house the battery cells, while the power compartment houses the power conversion device. The power conversion device and the battery cells can communicate and transmit power to each other, connected by signal lines and power lines. To prevent thermal runaway of the battery cells from affecting the normal operation of the power conversion device, battery compartment 1 and power compartment 2 must be isolated from each other, and the wiring points also need to be fixed and sealed.

[0041] The aforementioned fixing device 100 and energy storage unit, by setting a first flexible member 130, when the cover 120 is pressed onto the base 110, cause the first flexible member 130 to deform within the receiving groove 1111. The wire groove 131 adaptively adjusts according to the cable diameter, and then deforms to fit against the periphery of the cable, forming a continuous contact surface that wraps around the circumference of the cable. The wire groove 131 corresponds to the cable, fixing the cable more stably. While maintaining the stability of the cable fixation, the elastic contact avoids damage to the cable. The cover 120 is fastened to the base 110, which facilitates the installation and removal of the cable. The aforementioned fixing device 100 is installed on the compartment wall of the integrated energy storage unit. It can fix the cable at a specific position on the compartment wall 10 and seal it along the outer periphery of the cable. It is installed without gaps between the cable and the cable to isolate the space on both sides of the cable. The fixing device 100 is installed between the battery compartment 1 and the power compartment 2 to fix and seal the cable passing through the battery compartment 1 and the power compartment 2. This prevents a large amount of high-temperature smoke generated during battery thermal runaway from entering the power compartment 2, avoids corrosion or contamination of the sensitive electronic components of the power compartment 2, and prevents more serious accidents such as equipment failure, electrical short circuit and fire.

[0042] In one embodiment, the cover 120 is detachably connected to the base 110 or rotatably fastened to the base 110, so that the cover 120 and the base 110 form a separable and closable connection, which facilitates the disassembly and assembly and fixing of cables.

[0043] In one embodiment, the first flexible member 130 is made of silicone or rubber. Preferably, the rubber material can be nitrile rubber (NBR), silicone rubber, fluororubber (FKM), ethylene propylene diene monomer (EPDM), etc.

[0044] In one embodiment, the first flexible member 130 includes a protrusion 132 protruding from the surface of the cable tray 131. Specifically, at least one protrusion 132 is provided, and the top of the protrusion 132 has a protrusion height of 1-10 mm relative to the surface of the cable tray 131. The protrusion 132 can first contact the cable and undergo elastic deformation. After being squeezed, the protrusion 132 deforms and extends towards the periphery of the cable, which can fully fill the gap between the cable and the first flexible member 130. In particular, most cables have irregular shapes, and the protrusion 132 can fully adapt to the surface of the irregular shape. When the cable is further squeezed, the surface of the cable tray 131 also deforms, improving the sealing effect.

[0045] In one embodiment, the inner surface of the cable tray 131 is arc-shaped, with the center of the arc located inside the cable tray 131. The protrusion 132 is circumferentially arranged along the surface of the cable tray 131. The arc-shaped center of the cable tray 131 extends through the interior of the cable tray 131, causing the cable tray 131 to exceed half the circumference of the cable, thus fully enclosing most of the cable's outer circumference. The protrusion 132 is circumferentially arranged along the surface of the cable tray 131. When the protrusion 132 deforms, it extends laterally along the axial direction of the cable, widening its width to approach the width of the cable tray 131, ultimately filling the cable tray 131.

[0046] Specifically, the inner surface of the wire groove 131 is arc-shaped or elliptical. The protrusion 132 can extend parallel to the centerline of the arc-shaped wire groove 131, or it can be eccentrically positioned, or it can be spiral-shaped. There can be two or more protrusions 132, and the multiple protrusions 132, after deformation, are closer to the width of the wire groove 131.

[0047] In one embodiment, the first flexible member 130 is integrally formed and installed within a communicating receiving groove 1111. A plurality of wire-passing grooves 131 are formed on one side of the first flexible member 130. The multiple wire-passing grooves 131 have the same shape and size, or at least two of the multiple wire-passing grooves 131 have different shapes and sizes. In other embodiments, multiple first flexible members 130 are provided, each first flexible member 130 is sequentially installed within the receiving groove 1111, and the multiple wire-passing grooves 131 are respectively formed on one side of the multiple first flexible members 130.

[0048] In one embodiment, the base 110 includes a threading portion 111, which has a bottom wall and a side wall forming the receiving groove 1111. The bottom wall is disposed opposite to the groove opening, and the side wall has a thread outlet 1112 communicating with the thread passing groove 131. The groove opening is defined as the opening of the receiving groove 1111.

[0049] The cable outlet 1112 has the same shape as the cable groove 131. The cable outlet 1112 is located on both sides of the cable groove 131, that is, along the direction in which the cable passes (the axial direction of the cable groove 131). The sidewalls are located on both sides of the first flexible member 130 to limit the deformation direction of the first flexible member 130.

[0050] The bottom wall is stepped, with the height at both ends being higher than the height in the middle section, thus dividing the receiving groove 1111 into a first receiving portion 1113 and a second receiving portion 1114. The second receiving portion 1114 is located at both ends of the first receiving portion 1113, and the depth of the second receiving portion 1114 is less than the depth of the first receiving portion 1113. The upper edges of the first receiving portion 1113 and the second receiving portion 1114, together with the wire exit 1112, form the groove.

[0051] The first receiving portion 1113 accommodates multiple cable passage grooves 131 portions of the first flexible member 130. Corresponding to the receiving grooves 1111, the first flexible member 130 includes a middle portion 133 and end portions 134. The middle portion 133 forms the cable passage grooves 131 and is disposed in the first receiving portion 1113. The end portions 134 are located at both ends of the middle portion 133 and are disposed in the second receiving portion 1114. After the cover 120 is closed, the end portions 134 are compressed to make the positioning of the first flexible member 130 and the cable more stable.

[0052] Multiple wire outlets 1112 are spaced apart, and the sidewalls at the intervals between the wire outlets 1112 can abut against the lower side of the cover 120 after the cover 120 is closed, forming a closed structure. The multiple wire outlets 1112 are located in the first receiving part 1113.

[0053] In one embodiment, the edge of the wire outlet 1112 is lower than the top of the protrusion 132 on the surface of the wire channel 131, such that the protrusion 132 protrudes relative to the edge of the wire outlet 1112. Specifically, the edge of the wire outlet 1112 is lower than the entire protrusion 132, such that the edge of the wire outlet 1112 is lower than or flush with the surface of the wire channel 131. Alternatively, the edge of the wire outlet 1112 is lower than the highest point of the protrusion 132, and at least a portion of the protrusion 132 protrudes relative to the edge of the wire outlet 1112.

[0054] In one embodiment, the base 110 further includes a cable retainer 113 disposed at the cable outlet 1112, the cable retainer 113 being used to restrict the position of the cable accommodated in the cable channel 131. The cable can enter and pass through the cable retainer 113, but under certain circumstances, it can be restricted within the cable retainer 113. The cable retainer 113 can be located on the side of the base 110 facing the battery compartment 1, or on the side of the base 110 facing the power compartment 2, or cable retainers 113 can be provided on both sides of the base 110.

[0055] Specifically, the cable clip 113 includes a clip arm 1132, on which a limiting outlet 1131 is formed. The limiting outlet 1131 is flush with the upper edge of the base 110, and the width of the limiting outlet 1131 is less than the minimum width of the cable. After the cable is pressed into the clip arm 1132, the limiting outlet 1131 can prevent the cable from detaching, thereby securing the cable.

[0056] The upper edge of the base 110 is the upper edge of the side wall, which is also the upper edge of the cable tray 131. Specifically, the latch arm 1132 is located on the side of the side wall away from the first flexible member 130. A part of the latch arm 1132 encloses a channel matching the cable outlet 1112 for the cable to pass through, and the other part of the latch arm 1132 forms a limiting outlet 1131 at the upper edge of the base 110.

[0057] In one embodiment, the base 110 includes a support portion 112, the width of which increases in the direction away from the cover 120, and / or the width of the threaded portion 111 increases in the direction away from the cover 120. The support portion 112 connects to the compartment wall 10 and is disposed between the compartment wall 10 and the threaded portion 111, the width of which increases in the direction towards the compartment wall 10, and / or the width of the threaded portion 111 increases in the direction towards the compartment wall 10.

[0058] Specifically, the support part 112 and the wiring part 111 are integrally formed, and the base 110 has an overall trapezoidal shape. On the one hand, the widened base 110 can enhance the support stability of the base 110, and on the other hand, it is convenient to set a sealing layer on the outside of the fixing device 100. The support part 112 has a certain height, so that the wiring part 111 is at a certain distance from the compartment wall 10.

[0059] Furthermore, the support portion 112 includes a vertical wall 1121, a horizontal wall 1122, and a folded wall 1123. The vertical wall 1121 is perpendicular to the compartment wall 10, and the width of the vertical wall 1121 increases towards the compartment wall 10. The vertical wall 1121 is located between the threaded portion 111 and the compartment wall 10. The horizontal wall 1122 is perpendicular to the vertical wall 1121 and is located on both sides of the vertical wall 1121 in the width direction. The upper end of the horizontal wall 1122 extends and connects to the threaded portion 111, and the lower end of the horizontal wall 1122 abuts against the compartment wall 10. The folded wall 1123 is located on the side of the vertical wall 1121 away from the wire threading part 111. The folded wall 1123 is parallel to and abuts against the compartment wall 10. The folded wall 1123 is vertically arranged on the vertical wall 1121. The folded wall 1123 is provided with a through hole for installing a fastener to connect the support part 112 to the compartment wall 10.

[0060] In one embodiment, the fixing device 100 further includes a second flexible member 140, which is disposed on the cover 120 facing the receiving groove 1111. After the cover 120 is connected to the base 110, the second flexible member 140 can deform under force. After the cable is placed in the cable passage groove 131, the cover 120 is connected to the base 110. The cable is surrounded by the second flexible member 140 and the first flexible member 130. The second flexible member 140 and the first flexible member 130 deform under the compression of the cover 120, thus circumferentially sealing the cable.

[0061] Specifically, the second flexible member 140 is attached to one side of the cover 120 facing the base 110, or the cover 120 has a groove on one side facing the base 110, and the second flexible member 140 is disposed in the groove. At this time, at least a part of the second flexible member 140 needs to protrude out of the groove, or the second flexible member 140 is directly formed to one side of the cover 120 facing the base 110.

[0062] The second flexible member 140 is made of the same material as the first flexible member 130. In one embodiment, the second flexible member 140 is made of silicone or rubber. Preferably, the rubber material can be nitrile rubber (NBR), silicone rubber, fluororubber (FKM), ethylene propylene diene monomer (EPDM), etc. Preferably, the polyester material can be polytetrafluoroethylene (PTFE) or polyurethane (PU).

[0063] The second flexible member 140 can be an integral structure or a segmented structure. When the second flexible member 140 is an integral structure, its length is greater than or equal to the length of the first receiving portion 1113 of the base 110 (or the middle portion 133 of the first flexible member 130) to completely cover all the wire passage slots 131. When the second flexible member 140 is a segmented structure, there are multiple second flexible members 140, each matching one-to-one with a wire passage slot 131, and the length of each second flexible member 140 is greater than or equal to the width of the wire passage slot 131 to completely cover the wire passage slot 131.

[0064] In one embodiment, the surface of the second flexible member 140 is planar, or the surface of the second flexible member 140 has at least one arcuate groove.

[0065] Specifically, when the surface of the second flexible member 140 is planar, the cable is placed into the cable tray 131, and most of the cable is surrounded by the first flexible member 130. After the cover 120 is connected to the base 110, the second flexible member 140 and the first flexible member 130 are deformed under the pressure of the cover 120. The planar second flexible member 140 is squeezed out of the groove by the cable and deforms in the direction of filling the gap of the first flexible member 130. The planar second flexible member 140 can have a larger deformation to tightly seal the cable.

[0066] When the surface of the second flexible member 140 has a groove, the groove is correspondingly provided with the cable passage 131. The center of the arc-shaped groove is located outside the groove, and after the groove and the cable passage 131 are joined, the radial cross-sectional area of ​​the area enclosed by the groove and the cable passage 131 is smaller than the radial cross-sectional area of ​​the cable. When the cable is placed into the cable passage 131, most of the cable is surrounded by the first flexible member 130. After the cover 120 is connected to the base 110, the second flexible member 140 and the first flexible member 130 deform under the pressure of the cover 120 and deform in the direction of filling the gap of the first flexible member 130. The second flexible member 140 with the groove fits the outer periphery of the cable more closely, and can tightly seal the cable after deformation.

[0067] In one embodiment, the surface of the cover 120 facing the base 110 is provided with a connecting arm 123, and the end of the connecting arm 123 is provided with a hook 1231, which is used to engage and connect the base 110.

[0068] The cover 120 has a first side 121 and a second side 122. The first side 121 faces the base 110, and the second side 122 faces away from the base 110. The first side 121 has a fixing groove 1211 and / or a fixing hole 1212. The fixing groove 1211 has a recessed structure, and its shape matches the surface shape of the second flexible member 140 for mounting the second flexible member 140. The side of the second flexible member 140 facing away from the fixing groove 1211 protrudes from the edge of the fixing groove 1211 by 0-3mm. The fixing hole 1212 is located on one side or at the bottom of the fixing groove 1211. The two ends of the second side 122 have chamfered structures. The length of the cover 120 matches the length of the threaded portion 111, so that the second side 122 forms a smooth, continuous surface with the outer surface of the base 110, facilitating external sealing.

[0069] Specifically, the connecting arm 123 is located on the second side 122 and outside the fixing groove 1211. Multiple connecting arms 123 are provided, for example, four connecting arms 123, arranged in pairs. Each pair is located at both ends of the second side 122 of the cover 120, with the two connecting arms 123 in each pair symmetrically arranged. The connecting arms 123 are located on both sides of the second flexible member 140, perpendicular to the second side 122, and extend a certain distance.

[0070] The hook 1231 at the end of the connecting arm 123 is a protrusion on the inner surface of the connecting arm 123 (the surface facing the second flexible member 140). The hook 1231 engages with the lower edge of the wire threading part 111.
