Description

Technical Field

[0001] The present invention relates to the field of wire harness integrated boards, and specifically to a wire harness integrated board inside a battery pack with pre-installed guides. Background Art

[0002] During the installation process of the wire harness integrated board inside the battery pack, how to achieve precise, stable, and efficient installation of the CCS integrated busbar is a major challenge. Traditional installation methods lack effective pre-installed guides and reliable fixing structures. When installing the CCS integrated busbar, it is difficult to quickly and accurately position the CCS integrated busbar to the appropriate position, and installation deviations are likely to occur, resulting in low installation efficiency.

[0003] Moreover, relying only on simple connection methods, the connection between the CCS integrated busbar and the surrounding structures is not stable enough. During the use of the battery pack, affected by factors such as vibration, the CCS integrated busbar is prone to looseness, which in turn affects the connection stability of the wire harness inside the battery pack, and may even pose potential safety hazards, failing to meet the performance and safety requirements of the battery pack during actual use. Summary of the Invention

[0004] The purpose of the present invention is to provide a wire harness integrated board inside a battery pack with pre-installed guides to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A wire harness integrated board inside a battery pack with pre-installed guides includes a CCS integrated busbar and limiting strips supported on both sides of the CCS integrated busbar. Connection pieces are fixed at both ends of the CCS integrated busbar, fixing pieces are fixed on the surface of the limiting strips, positioning plugs are fixed on the surface of the fixing pieces, and the positioning plugs are inserted into the surface of the connection pieces; The height of the positioning plug is greater than the thickness of the connection piece, and stoppers are inserted on both sides of the positioning plug, and the stoppers block above the connection piece.

[0006] Preferably, the limiting strip has a "U" - shaped plate structure, and the two parallel side plates of the limiting strip are respectively pressed against the two side walls of the CCS integrated busbar.

[0007] Preferably, there are two fixing pieces, and the two fixing pieces are respectively distributed at both ends of the limiting strip. Edge grooves are opened on both sides of the fixing piece, through holes two are opened on the bottom surface of the edge groove, and anti - loosening screws are inserted into the through holes two.

[0008] Preferably, a reserved hole is opened on the surface of the connection piece, the reserved hole is an oblong hole, the positioning plug penetrates through the reserved hole, and the positioning plug is an oblong block.

[0009] Preferably, the positioning block has reserved slots on both sides, the bottom surface of the reserved slots and the top surface of the connecting piece are coplanar, one end of the stop block is inserted into the reserved slot, and a rubber support block is fixed between one end of the stop block and the reserved slot.

[0010] Preferably, the other end of the stop block has an inclined surface on the top surface. When the rubber support block is in the initial state, a pre-reserved groove is partially exposed on the inclined surface, and the width of the rubber support block is smaller than the width of the pre-reserved groove.

[0011] Preferably, the top surface of the positioning insert has a notch, the bottom surface of the notch and the top surface of the connecting piece are coplanar, and the bottom surface of the notch has a second through hole that penetrates the bottom surface of the fixing piece.

[0012] Preferably, a rubber pad is fixed to the bottom surface of the notch, the inner ring diameter of the rubber pad is larger than the diameter of the first perforation, and a reinforcing screw is inserted into the first perforation.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The present invention proposes a pre-installed guide for the internal wiring harness integration board of a battery pack. Two limiting strips are pre-fixed to the internal substrate of the battery pack, ensuring that the distance between the two limiting strips is equal to the board length of the CCS integrated busbar. When the CCS integrated busbar is pushed between the two limiting strips, it is precisely positioned by the two limiting strips, achieving initial positioning. This design provides clear guidance for the installation of the CCS integrated busbar, greatly improving the accuracy and efficiency of installation and reducing repeated adjustments caused by inaccurate positioning during the installation process.

[0014] The fixing plates on the surface of the limiting strip have side grooves on both sides, and two through holes are formed on the bottom surface of the side grooves. Anti-loosening screws are screwed onto the substrate surface through these through holes, firmly fixing the fixing plates to the substrate. Since the two fixing plates are distributed at both ends of the limiting strip, they simultaneously exert a traction force on the limiting strip, thus stably limiting it to the substrate. This installation method ensures that the limiting strip will not easily loosen during battery pack use, providing a reliable support and limiting foundation for the CCS integrated busbar.

[0015] The positioning block is taller than the connecting piece, and has stoppers on both sides. The connecting piece has a pre-drilled, elongated hole on its surface, through which the positioning block passes. Pre-drilled grooves are formed on both sides of the positioning block. One end of the stopper is inserted into the groove, and a rubber support is fixed between the stopper and the groove. The other end of the stopper has a beveled top surface. When the CCS integrated busbar is inserted between the two limiting strips, with the end of the connecting piece resting on the fixing piece and the positioning block passing through the pre-drilled hole, the connecting piece pushes the stopper into the groove along the bevel, causing the rubber support to deform elastically. When the bottom surface of the connecting piece overlaps the top surface of the fixing piece, the rubber support rebounds, pushing the stopper back, causing the stopper to block above the connecting piece, thus pre-fixing the end of the connecting piece to the fixing piece. This pre-fixing method is simple to operate and can quickly achieve initial fixation of the CCS integrated busbar without the use of complex tools, facilitating subsequent final fixation operations.

[0016] A notch is cut into the top surface of the positioning insert, and a second through hole is cut into the bottom surface of the notch, penetrating the bottom surface of the fixing plate. A rubber pad is fixed to the bottom surface of the notch, and the inner ring diameter of the rubber pad is larger than the diameter of the first through hole. A reinforcing screw is inserted into the first through hole. After pre-fixing, the reinforcing screw is screwed onto the substrate through the second through hole, which further reinforces the installation of the CCS integrated busbar on the substrate. The rubber pad not only acts as a buffer, reducing the impact of vibration on the connection, but also increases the friction at the connection point, making the connection of the reinforcing screw more stable. This effectively prevents the CCS integrated busbar from loosening due to vibration or other reasons during battery pack use, ensuring the stability and reliability of the wiring harness connection inside the battery pack.

Detailed Implementation

[0019] In order to clearly and completely describe the objectives, technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Please refer to Figures 1-5 , the present invention provides a technical solution: an internal wire harness integrated board of a battery pack with pre-installed guiding, including a CCS integrated busbar 1 and limiting strips 2 supported on both sides of the CCS integrated busbar 1. Connection pieces 101 are fixed at both ends of the CCS integrated busbar 1, and fixing pieces 3 are fixed on the surface of the limiting strips 2. Positioning inserts 301 are fixed on the surface of the fixing pieces 3, and the positioning inserts 301 are inserted into the surface of the connection pieces 101; the limiting strips 2 are in a "U"-shaped plate structure, and the two parallel side plates of the limiting strips 2 are respectively pressed against the two side walls of the CCS integrated busbar 1.

[0021] There are two fixing pieces 3, and the two fixing pieces 3 are respectively distributed at both ends of the limiting strips 2. Side grooves 306 are opened on both sides of the fixing pieces 3, and through holes two 307 are opened on the bottom surface of the side grooves 306. Anti-loosening screws 5 are inserted into the through holes two 307.

[0022] The two limiting strips 2 are pre-fixed on the internal substrate of the battery pack to ensure that the distance between the two limiting strips 2 is equal to the board length of the CCS integrated busbar 1. After the CCS integrated busbar 1 is pushed between the two limiting strips 2, the CCS integrated busbar 1 is limited by the two limiting strips 2 to achieve preliminary positioning; when installing the limiting strips 2, only need to pass the anti-loosening screws 5 through the through holes two 307 and then screw them on the surface of the substrate. At this time, the fixing pieces 3 are fixed on the substrate, and the two fixing pieces 3 simultaneously pull the limiting strips 2, so as to limit the limiting strips 2 on the substrate.

[0023] In order to fix the CCS integrated busbar 1 between the two limiting strips 2, it is proposed that: The height of the positioning block 301 is greater than the thickness of the connecting piece 101. Stops 4 are inserted into both sides of the positioning block 301, blocking the top of the connecting piece 101. A pre-drilled hole 102 is formed on the surface of the connecting piece 101. The pre-drilled hole 102 is an elongated oval hole, through which the positioning block 301 passes. The positioning block 301 is an elongated oval block. Pre-drilled grooves 305 are formed on both sides of the positioning block 301. The bottom surface of the pre-drilled groove 305 is coplanar with the top surface of the connecting piece 101. One end of the stop 4 is inserted into the pre-drilled groove 305, and a rubber support 4 is fixed between one end of the stop 4 and the pre-drilled groove 305. 01; The other end of the stop block 4 has a slope on the top surface. When the rubber support block 401 is in the initial state, the slope partially exposes the reserved groove 305. The width of the rubber support block 401 is smaller than the width of the reserved groove 305. The top surface of the positioning insert block 301 has a notch 302. The bottom surface of the notch 302 and the top surface of the connecting piece 101 are coplanar. The bottom surface of the notch 302 has a second through hole 307. The second through hole 307 penetrates the bottom surface of the fixing piece 3. A rubber pad 304 is fixed to the bottom surface of the notch 302. The inner ring diameter of the rubber pad 304 is larger than the hole diameter of the first through hole 303. A reinforcing screw 6 is inserted into the first through hole 303.

[0024] When the CCS integrated busbar 1 is inserted between the two limiting strips 2, the end of the connecting piece 101 is laid on the fixing piece 3, and the positioning block 301 passes through the reserved hole 102. During the falling process of the connecting piece 101, the connecting piece 101 pushes the stop 4 into the reserved groove 305 along the inclined surface. At this time, the rubber support block 401 is squeezed by the corresponding stop 4 and undergoes elastic deformation. When the bottom surface of the connecting piece 101 overlaps the top surface of the fixing piece 3, the stop 4 is above the connecting piece 101. That is, at this time, the rubber support block 401 rebounds and pushes the stop 4 back. The stop 4 blocks the top of the connecting piece 101, thereby pre-fixing the end of the connecting piece 101 on the fixing piece 3. Then, the reinforcing screw 6 is passed through the second through hole 307 and screwed onto the substrate. The reinforced CCS integrated busbar 1 is laid and installed on the substrate.

[0025] Instructions for using the battery pack internal wiring harness integration board with pre-installed guide: Two limiting strips 2 are pre-fixed to the internal substrate of the battery pack, ensuring that the distance between the two limiting strips 2 is equal to the board length of the CCS integrated busbar 1. When installing the limiting strips 2, anti-loosening screws 5 are used. The anti-loosening screws 5 are passed through the through hole 307 opened on the bottom surface of the side groove 306 of the fixing piece 3 and screwed onto the surface of the substrate. At this time, the fixing piece 3 is fixed on the substrate. Since the two fixing pieces 3 are respectively distributed at both ends of the limiting strip 2, the two fixing pieces 3 simultaneously pull the limiting strip 2, thereby limiting the limiting strip 2 on the substrate.

[0026] Push the CCS integrated busbar 1 between the two limit bars 2. Since the distance between the two limit bars 2 is equal to the board length of the CCS integrated busbar 1, the CCS integrated busbar 1 is limited by the two limit bars 2 to achieve preliminary positioning. At this time, the limit bar 2 is in a "匚"-shaped plate structure, and its two parallel side plates are respectively pressed against the two side walls of the CCS integrated busbar 1.

[0027] After the CCS integrated busbar 1 is inserted between the two limit bars 2, the end of the connecting piece 101 is laid on the fixing piece 3. Since the height of the positioning plug 301 is greater than the thickness of the connecting piece 101, the positioning plug 301 penetrates through the reserved hole 102 in the shape of an oblong hole opened on the surface of the connecting piece 101. During the falling process of the connecting piece 101, the connecting piece 101 squeezes the stop block 4 into the reserved grooves 305 opened on both sides of the positioning plug 301 along the inclined surface of the top surface of the other end of the stop block 4. At this time, the rubber support block 401 fixed between one end of the stop block 4 and the reserved groove 305 is elastically deformed by the corresponding stop block 4. When the rubber support block 401 is in the initial state, a part of the inclined surface leaks out of the reserved groove 305, and the width of the rubber support block 401 is smaller than the width of the reserved groove 305. After the bottom surface of the connecting piece 101 is lapped on the top surface of the fixing piece 3, the stop block 4 is above the connecting piece 101. At this time, the rubber support block 401 rebounds to push the stop block 4 to rebound, and the stop block 4 blocks above the connecting piece 101, thereby pre-fixing the end of the connecting piece 101 on the fixing piece 3.

[0028] A notch 302 is opened on the top surface of the positioning plug 301. The bottom surface of the notch 302 and the top surface of the connecting piece 101 are coplanar. A through hole two 307 is opened on the bottom surface of the notch 302, and the through hole two 307 penetrates through the bottom surface of the fixing piece 3. A rubber pad 304 is fixed on the bottom surface of the notch 302. The inner ring diameter of the rubber pad 304 is greater than the aperture of the through hole one 303. Pass the reinforcement screw 6 through the through hole two 307 and then screw it on the substrate to reinforce the laying and installation of the CCS integrated busbar 1 on the substrate.
