Description

Technical Field

[0001] This disclosure relates to the field of battery pack technology, and in particular to a wire buckle structure and a battery pack. Background Technology

[0002] The battery pack casing has a hole through which the wiring harness is electrically connected to the battery pack, allowing the battery pack to conduct electricity externally through the wiring harness. At the same time, the location where the wiring harness passes through the hole needs to be sealed with glue.

[0003] However, due to the large number of wires in the wire harness, it is difficult to apply adhesive at the holes where the wire harness passes through, which increases the difficulty of the application process, and the adhesive strength at the holes is also poor. Summary of the Invention

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a wire clip structure and battery pack with lower adhesive application difficulty.

[0005] The purpose of this disclosure is achieved through the following technical solution: A snap-fit ​​structure for covering a housing, the snap-fit ​​structure comprising: Enclosure section; The branch section is connected to the enclosure section. At least two wire holes are formed on the outer periphery of the branch section. Each wire hole is used to pass through and snap onto an external cable. At least one of the enclosure section and the branch section is provided with a snap-fit ​​member, which is used to snap onto the snap-fit ​​hole of the housing when covered.

[0006] In one embodiment, there are two snap-fit ​​components, namely a first snap-fit ​​component and a second snap-fit ​​component. The first snap-fit ​​component is provided on the enclosure part, and the second snap-fit ​​component is provided on the dividing line part. The first snap-fit ​​component and the second snap-fit ​​component are respectively snapped into the snap-fit ​​hole.

[0007] In one embodiment, the enclosure portion and the dividing line portion are integrally formed.

[0008] In one embodiment, the cross-section of the wire hole is U-shaped.

[0009] In one embodiment, a material feeding groove is formed on the dividing section.

[0010] In one embodiment, a clearance opening is also formed on the enclosure portion, and the clearance opening is positioned directly opposite the first snap-fit ​​member.

[0011] In one embodiment, one side of the enclosure is fixedly connected to one side of the dividing line.

[0012] A battery pack, characterized in that it includes a housing, a cable assembly, a battery module, a sealing material, and a wire buckle structure as described in any of the above embodiments. The housing has a snap-fit ​​hole, the wire buckle structure covers the snap-fit ​​hole, and the snap-fit ​​member snaps into the snap-fit ​​hole. The cable assembly includes at least two external cables, and each through-hole is through which a first end of an external cable is snapped. The battery module is disposed inside the housing and is electrically connected to a second end of the cable assembly. The sealing material at least fills the area enclosed by the inner walls of each through-hole and the snap-fit ​​hole to seal each external cable.

[0013] In one embodiment, there are multiple external cables and multiple through holes, with each external cable corresponding to one of the multiple through holes and connected via a snap-fit ​​mechanism; and / or, The sealant is also used to fill the gap between the outer periphery of the wire-lock structure and the housing.

[0014] In one embodiment, there are multiple sealant components, each of which fills the area enclosed by the inner wall of the corresponding wire hole and the card hole.

[0015] Compared with the prior art, this disclosure has at least the following advantages: 1) In the above-mentioned wire buckle structure, since at least one of the enclosure part and the branch part is provided with a snap-fit ​​component, the snap-fit ​​component can snap into the snap-fit ​​hole when it is covered on the housing, so that the wire buckle structure is snapped onto the housing of the battery pack, which facilitates the assembly of the wire buckle structure and the battery pack and shortens the alignment time of the wire buckle structure and the battery pack pre-assembly alignment.

[0016] 2) Each wire hole is used to pass through and snap on external cables. Before the snap-fit ​​is snapped into the snap hole and covered by the housing, the external cables can be passed through and snapped into the corresponding wire hole one by one, so as to separate two adjacent external cables. The sealant is filled in the area enclosed by the inner wall of each wire hole and snap hole, which reduces the difficulty of the glue application operation and increases the sealing and bonding strength of a single external cable.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 4 In one embodiment, a wire fastener structure 10 is used to cover a housing 20a. The wire fastener structure 10 includes a retaining portion 100 and a branching portion 200. The branching portion 200 is connected to the retaining portion 100, and at least two wire through holes 210 are formed on the outer periphery of the branching portion 200. Each wire through hole 210 is used to pass through and snap onto an external cable 201b. At least one of the retaining portion 100 and the branching portion 200 is provided with a snap-fit ​​member 110, which is used to snap onto the snap-fit ​​hole 201a of the housing 20a when it is covered on the housing 20a.

[0023] During assembly, one end of the cable assembly 20b can be electrically connected to the battery pack 20. Specifically, one end of each external cable 201b in the cable assembly 20b is electrically connected to the battery pack 20. Then, the other end of each external cable 201b is passed through the corresponding wire hole 210 on the outer periphery of the branch section 200 to separate the external cable 201b and lock it into the wire hole 210. Then, the snap-fit ​​member 110 of the branch section is snapped into the snap hole 201a, and then the snap-fit ​​member 110 of the enclosure section 100 is snapped into place. The wire buckle structure 10 is attached to the snap hole 201a, allowing it to be fixed to the housing 20a, thus covering the housing 20a. Then, a sealant application operation can be performed at the location where the wire buckle structure 10 covers the housing 20a, that is, the sealant is filled into the area enclosed by the inner wall of each wire hole 210 and the snap hole 201a, so that the sealant fits and seals the gap between each external cable 201b and the wire hole 210, thereby seamlessly sealing and fixing the external cable 201b to the wire hole through the sealant, and finally completing the assembly between the wire buckle structure 10 and the battery pack 20.

[0024] The aforementioned wire buckle structure 10, since at least one of the enclosure portion 100 and the branch portion 200 is provided with a snap-fit ​​member 110, allows the snap-fit ​​member 110 to snap into the snap-fit ​​hole 201a when it is covered on the housing 20a, so that the wire buckle structure 10 snaps onto the housing 20a of the battery pack 20, which facilitates the assembly of the wire buckle structure 10 and the battery pack 20 and shortens the alignment time of the wire buckle structure 10 and the battery pack 20 during pre-assembly alignment.

[0025] Each wire hole 210 is used to pass through and snap on an external cable 201b. Before the snap-fit ​​member 110 snaps into the snap-fit ​​hole 201a and covers the housing 20a, the external cables 201b can be passed through and snapped into the corresponding wire hole 210 one by one, thereby separating two adjacent external cables 201b. The sealant is filled in the area enclosed by the inner wall of each wire hole 210 and the snap-fit ​​hole 201a, which reduces the difficulty of the glue application operation and increases the sealing and bonding strength of a single external cable 201b.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, there are two snap-fit ​​members 110, namely a first snap-fit ​​member 111 and a second snap-fit ​​member 112. The first snap-fit ​​member 111 is provided on the enclosure part 100, and the second snap-fit ​​member 112 is provided on the branching part 200. Both the first snap-fit ​​member 111 and the second snap-fit ​​member 112 are snapped into the snap-fit ​​hole. In this embodiment, when the wire buckle structure 10 is installed, the second snap-fit ​​member 112 is first snapped into the snap-fit ​​hole 201a to position the wire buckle structure 10 and ensure that the position of the wire buckle structure 10 is accurately installed. Then, the first snap-fit ​​member 111 is snapped into the snap-fit ​​hole 201a to complete the fixation of the wire buckle structure 10 on the housing 20a.

[0027] Furthermore, the first snap-fit ​​member 111 and the second snap-fit ​​member 112 are arranged opposite to each other. In this way, when the wire buckle structure 10 is installed on the housing 20a, the wire buckle structure 10 and the housing 20a can be accurately positioned, preventing misalignment during installation. In this embodiment, the first snap-fit ​​member 111 is located at the end of the enclosure portion opposite to the dividing line portion, and the second snap-fit ​​member 112 is located at the end of the dividing line portion opposite to the enclosure portion.

[0028] like Figure 2 As shown, in one embodiment, the end of the first snap-fit ​​member 111 away from the blocking portion 100 is provided with an inner flange 1111. Thus, when the first snap-fit ​​member 111 is snapped into the housing 20a, the inner flange 1111 positions the snap-fit ​​hole 201a, guiding the first snap-fit ​​member to smoothly snap into the inner wall of the housing 20a through the snap-fit ​​hole 201a, thereby improving the assembly guiding function of the snap-fit ​​structure 10 and thus increasing the assembly efficiency of the snap-fit ​​structure 10.

[0029] like Figure 6As shown, in one embodiment, the second snap-fit ​​member 112 has an outer flange 1121 at the end away from the branch section 200. Since the wire buckle structure 10 needs to be snapped into the housing 20a via the second snap-fit ​​member 112 before installation, the outer flange 1121 initially positions the wire buckle structure 10 into the snap hole 201a, preventing incorrect installation. Simultaneously, the outer flange 1121 enhances the support of the second snap-fit ​​member 112 within the snap hole 201a, further strengthening the stability of the wire buckle structure 10 and preventing it from wobbling within the housing 20a. Furthermore, when the second snap-fit ​​member 112 is snapped into the housing 20a, it improves the assembly guiding function of the wire buckle structure 10, guiding the first snap-fit ​​member 111 to smoothly slide into the snap hole 201a of the housing 20a, thereby improving the assembly efficiency of the wire buckle structure 10.

[0030] like Figure 6 As shown, in one embodiment, a snap-fit ​​groove 1122 is formed between the second snap-fit ​​member 112 and the outer flange 1121. Thus, when the second snap-fit ​​member 112 engages with the snap-fit ​​hole 201a, the snap-fit ​​groove 1122 forms an interference fit with the housing 20a, allowing the second snap-fit ​​member 112 to be securely positioned and assembled on the housing 20a. Furthermore, the dividing section 200 has an opening groove 1123 communicating with the snap-fit ​​groove 1122. The opening groove 1123 is correspondingly provided with the second snap-fit ​​member 112, facilitating the processing and forming of the second snap-fit ​​member 112 and reducing the forming difficulty of the wire buckle structure.

[0031] In one embodiment, the enclosure portion 100 and the branch portion 200 are integrally formed. This ensures the overall structural strength of the buckle structure 10 and also better seals the casing 20a of the battery pack 20.

[0032] See again Figure 2 In one embodiment, the cross-section of the wire hole 210 is U-shaped. In this way, the cross-section of the wire hole 210 can be smoothly transitioned to reduce sharp parts on the cross-section, avoid scratching the external cable 201b, and extend the service life of the external cable 201b.

[0033] Review Figure 2 In one embodiment, a material extraction groove 220 is formed on the wire divider 200. This reduces the material required for the wire clip structure 10, and also increases the elastic stress of the wire clip structure 10, resulting in a tighter connection between the wire clip structure 10 and the housing 20a. Simultaneously, during the sealant application operation, sealant can be applied along the edge of the material extraction groove 220 to the wire passage hole 210, resulting in a more uniform area of ​​sealant application.

[0034] Review Figure 2Furthermore, the end of the enclosure portion 100 away from the dividing portion 200 is provided with a limiting protrusion 130. After the wire buckle structure 10 is snapped and assembled into the housing 20a, the limiting protrusion 130 is limited and abuts against the outer wall of the housing 20a, so that the enclosure portion is better limited and assembled around the periphery of the buckle hole under the combined action of the limiting protrusion 130 and the first snap-fit ​​member, thereby preventing the wire buckle structure from moving on the housing 20a. At the same time, when the wire buckle structure 10 is glued, it can be effectively glued.

[0035] See again Figure 2 In one embodiment, the enclosure portion 100 also has a recess 120, which is positioned directly opposite the first snap-fit ​​member 111. When it is necessary to remove the fastener structure 10 from the housing 20a, the first snap-fit ​​member 111 is pressed through the recess 120, causing it to disengage from the snap hole 201a, thus facilitating the removal of the fastener structure 10 from the housing 20a. The number of recesses 120 corresponds to the number of first snap-fit ​​members 111.

[0036] In this embodiment, there are two clearance openings 120. Both clearance openings 120 are opened on the limiting protrusion 130, so that a gripping protrusion 121 is formed between the two clearance openings 120, so that the wire buckle structure 10 can be gripped on the gripping protrusion 121 when it is snapped and assembled onto the housing 20a, making it convenient for the operator to install the wire buckle structure onto the housing 20a.

[0037] See again Figure 2 In one embodiment, each gripping protrusion 121 clamps the housing 20a. This prevents the wire buckle structure 10 from shifting from the housing 20a and prevents the sealant on the wire hole 210 from falling off inside the housing 20a.

[0038] See again Figure 2 In one embodiment, the first snap-fit ​​member 111 and the gripping protrusion 121 are misaligned to form a snap-fit ​​area 140, so that the wire buckle structure 10 is effectively snapped and positioned with the inner wall of the snap hole of the housing 20a.

[0039] See Figure 7 In one embodiment, the wire divider 200 is further provided with a plurality of first reinforcing ribs 230, each first reinforcing rib 230 being disposed on the back side of the wire divider, wherein every two first reinforcing ribs 230 are disposed opposite each other on both sides of the wire hole 210. This makes the stress distribution of the wire buckle structure 10 more uniform, improves the bending and torsional deformation resistance of the wire divider 200, makes the structure of the entire wire buckle structure 10 more stable, and extends the service life of the wire buckle structure 10.

[0040] See again Figure 7In one embodiment, the connection between the two ends of each first reinforcing rib 230 and the branch portion 200 is also formed with an arc transition. When the buckle structure 10 is connected to the housing 20a, a sealant gap exists between the buckle structure 10 and the housing 20a, preventing excessive compression of the housing 20a by the buckle structure 10 and preventing deformation at the connection point between the buckle structure 10 and the housing 20a. Furthermore, when the buckle structure 10 is sealed with sealant, the sealant can enter through the wire-locking hole and form between the buckle structure 10 and the housing 20a, thereby increasing the sealing performance between them. Simultaneously, through the adhesive area of ​​the sealant with both the buckle structure 10 and the housing 20a, the sealant is effectively sealed and fixed between the buckle structure 10 and the housing 20a.

[0041] See again Figure 7 In one embodiment, the branch section 200 is further provided with a second reinforcing rib 240, which perpendicularly penetrates each of the first reinforcing ribs 230. This forms a truss structure with the first reinforcing ribs 230, improving the toughness and torsional resistance of the branch section 200 and preventing uneven stress distribution in certain areas. This prevents tearing of the branch section 200 caused by buckling of a single first reinforcing rib, and also protects the wire hole 210 from external pressure, ensuring it maintains its original shape. Simultaneously, the truss structure formed by the second reinforcing rib 240 and the first reinforcing rib 230 strengthens the rigidity of the wire fastener structure 10, allowing stress to redistribute through the truss structure. This prevents excessive stress concentration in the branch section 200, reduces fatigue cracks, and further extends the service life of the wire fastener structure 10.

[0042] See Figure 8 and Figure 9 Furthermore, a sealing edge 202a is provided on the housing 20a near the branch section 200 to better apply and cure the sealant between the branch section 200 and the housing 20a, thereby better sealing the wire harness at the snap-fit ​​joint between the wire buckle structure 10 and the housing 20a. It can also support and limit the cured sealant, so that the sealant is better formed between the branch section 200 and the housing 20a, and prevent the sealant from falling off from the branch section 200.

[0043] In this embodiment, the adhesive-blocking edge 202a is provided correspondingly to the outer periphery of the branch line portion 200, so that the wire passage hole on the outer periphery of the branch line portion 200 is better sealed with adhesive.

[0044] See again Figure 2In one embodiment, one side of the enclosure portion 100 is fixedly connected to one side of the branch portion 200, that is, the branch portion 200 protrudes from one side of the enclosure portion 100, and one end of the branch portion 200 extends beyond the enclosure portion 100. This allows the side of the branch portion 200 near the housing 20a to have a larger accommodating space, thereby allowing the sealant to be better formed between the branch portion 200 and the housing 20a.

[0045] Since one side of the enclosure 100 is fixedly connected to one side of the branch line 200, so as to better enclose and seal the wire hole with the glue-blocking edge 202a, when the wire buckle structure 10 is installed on the housing 20a, the user first holds the branch line 200 to snap the second snap-fit ​​member 112 onto the housing 20a, and then holds and snaps the first snap-fit ​​member 111 onto the snap hole 201a of the housing 20a.

[0046] It should be noted that when the external cable 201b is inserted into the cable passage hole 210, if the portion of the external cable 201b extending into the housing 20a is relatively long, the longer portion can be tucked into the receiving space. This allows the operator to easily apply sealant between the branch section 200 and the enclosure section 100. Simultaneously, the sealant can be applied to seal both the portion of the external cable 201b outside the housing 20a and the cable passage hole 210, and the sealant is further secured and fixed between the branch section and the housing 20a by the sealant-blocking edge, better preventing the sealant from falling off.

[0047] See also Figure 8 and Figure 9 In one embodiment, a limiting flange 203a is further provided on the housing 20a, wherein the limiting flange 203a abuts against the wire fastener assembly 10. This further enhances the stability of the wire fastener structure 10 on the housing 20a. Simultaneously, the limiting flange 203a prevents the wire fastener structure 10 from being over-installed, acting as a stop to prevent the wire fastener structure 10 from being trapped inside the housing 20a by external forces.

[0048] See again Figure 1 , Figure 1a and Figure 6This application also provides a battery pack 20, including a housing 20a, a cable assembly 20b, a battery module 20c, and a sealing material (not shown) and a wire buckle structure 10 in any of the above embodiments; the battery module 20c is disposed inside the housing 20a, the housing 20a has a snap hole 201a, the wire buckle structure 10 is disposed on the snap hole 201a, and the snap fastener 110 is snapped into the snap hole 201a; the cable assembly 20b includes at least two external cables 201b, one end of the external cables 201b is electrically connected to the battery module, and each wire through hole 210 passes through and snaps into the first end of the corresponding external cable 201b; the battery module 20c is disposed inside the housing, and the battery module 20c is electrically connected to the second end of the cable assembly 20b; the sealing material fills the area enclosed by each wire through hole 210 and the inner wall of the snap hole 201a to seal each external cable 201b.

[0049] During assembly, the battery pack 20 described above can be assembled by first connecting the second end of the external cable 201b to the battery module 20c, then threading the first end of the external cable 201b through and snapping it into the wire hole 210 to separate and fix the two adjacent external cables 201b. After that, sealant is filled into the area enclosed by the inner wall of the wire hole 210 and the snap hole 201a to seal the gap between the external cable 201b and the wire hole 210, and finally the assembly of the battery pack 20 is completed.

[0050] Review Figure 1a In one embodiment, there are multiple external cables 201b and multiple wire-through holes 210, with each external cable 201b corresponding to a specific wire-through hole 210 and connected via a snap-fit ​​connection; and / or, In one embodiment, the sealant is also used to fill the gap between the outer periphery of the wire buckle structure 10 and the housing 20a. In this way, the sealant seals the space between the wire buckle structure 10 and the housing 20a, preventing water from entering the battery pack 20 through the gap between the outer periphery of the wire buckle structure 10 and the housing 20a, thus avoiding damage to the battery pack 20.

[0051] In one embodiment, there are multiple sealing elements, each of which fills the area enclosed by the inner wall of the corresponding wire hole 210 and the locking hole 201a. This seals the gap between the external cable 201b and the wire hole 210, thus securing and sealing the external cable 201b.

[0052] Compared with the prior art, this disclosure has at least the following advantages: 1. Since at least one snap-fit ​​member 110 is provided on the enclosure part 100 and the branch line part 200, the snap-fit ​​member 110 can snap into the snap hole 201a when it is covered on the housing 20a, so that the wire buckle structure 10 is snapped onto the housing 20a of the battery pack 20, which facilitates the assembly of the wire buckle structure 10 and the battery pack 20 and shortens the alignment time of the pre-assembly alignment of the wire buckle structure 10 and the battery pack 20.

[0053] 2. Each wire hole 210 is used to pass through and snap on the external cable 201b. Before the snap-fit ​​part 110 is snapped into the snap-fit ​​hole and covered on the housing 20a, the external cables 201b can be passed through and snapped into the corresponding wire hole 210 one by one, so as to separate two adjacent external cables 201b. The sealant is filled in the area enclosed by the inner wall of each wire hole 210 and the snap-fit ​​hole 201a, thereby reducing the difficulty of the glue application operation and increasing the sealing and bonding strength of a single external cable 201b.

[0054] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
