[0047] The cable protection box 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0048] like Figure 1 and Figure 2 As shown, the cable guard box 100 according to an embodiment of the present invention is used in a vehicle and includes a housing 10.

[0049] Specifically, see the attached document. Figure 2 and attached Figure 3 As shown, the housing 10 has a receiving cavity and a first through hole 21 and a second through hole 33 communicating with the receiving cavity. The first through hole 21 is located at the lower end of the housing 10 and runs along the vertical direction (e.g., ...). Figure 1 (As shown) extends, and the second through hole 33 is provided on the rear side of the housing 10 and along the front-rear direction (as shown). Figure 2As shown, the first wiring harness connector extending from the cab to the outside can be inserted into the receiving cavity through the second through hole 33 and fixed inside the receiving cavity. The second wiring harness connector outside the cab can be inserted into the receiving cavity through the first through hole 21 and plugged into the first wiring harness connector. Through the insertion of the first and second wiring harness connectors into the receiving cavity, the outer shell can completely cover the first and second wiring harness connectors, avoiding messiness of the wiring harness 200, improving the neatness of the wiring harness 200, and making the appearance of the wire protection box 100 simple, elegant and beautiful.

[0050] It should be noted that since the water ingress direction in the front engine compartment of a vehicle is mostly from top to bottom and from outside to inside, this utility model, by making the opening of the first through hole 21 face downwards and the opening of the second through hole 33 face backwards, can effectively improve the waterproof performance of the cable protection box 100, and play a protective and waterproof role for the first and second wire harness connectors, avoiding short circuits, corrosion, damage, etc. of the wire harness 200, and preventing more serious situations such as burning and fire, thus ensuring the reliability of the cable protection box 100 and improving the safety performance of the vehicle.

[0051] In existing technology, the wiring harness in the cab passes through the front bulkhead sheet metal of the vehicle body via a through-hole rubber sleeve, and then is connected in the front engine compartment using waterproof connectors. Generally, there are many wiring harnesses inside and outside the cab, requiring many large wiring harness connectors. Directly using waterproof connectors has several drawbacks: first, it leads to a scattered, messy, and unsightly layout in the front engine compartment; second, waterproof connectors are expensive, risky, and the fixing structure is too small for the connector body, resulting in unreliable fixing; third, it is not conducive to the expansion of subsequent functions; and fourth, the structure of waterproof connectors is relatively complex, making it inconvenient to troubleshoot and repair terminals and connectors.

[0052] The cable protection box 100 of this utility model can protect and waterproof the first and second wire harness connectors, thereby relatively reducing the requirements for waterproofing and sealing of the first and second wire harness connectors. It eliminates the need for waterproof connectors. Firstly, it relatively reduces the external packaging cost of the first and second wire harness connectors, allowing the wire harness 200 to be simply wrapped with tape, thus reducing the cost of the wire harness 200. Secondly, it makes the wiring in the front engine compartment neater, improving the aesthetics of the front engine compartment. Thirdly, it improves the reliability of the connection between the first and second wire harness connectors. Fourthly, it reduces the structural complexity of the first and second wire harness connectors, allowing for centralized placement of the wire harness connectors and facilitating troubleshooting and maintenance.

[0053] It should be noted that both the first via 21 and the second via 33 are in the left-right direction (e.g., Figure 1 The number and size of the multiple vias arranged on the surface (as shown) can be adjusted according to the user's actual needs.

[0054] Preferably, the first and second wire harness connectors can be selected from the same series of wire harness connectors. Different sheath fixing structures within the same series are similar, which can reduce mold complexity and mold repair costs. The fixing structure of the sheath can be selected with different codes and colors within the same series to prevent errors and facilitate the assembly of wire harness 200.

[0055] According to the embodiment of the present utility model, the cable protection box 100, by providing a first through hole 21 and a second through hole 33 on the housing 10, the first through hole 21 is provided at the lower end of the housing 10 and extends in the vertical direction, and the second through hole 33 is provided at the rear side of the housing 10 and extends in the front-back direction, can effectively improve the waterproof performance of the cable protection box 100, ensure the reliability of the cable protection box 100, improve the safety performance, and also play a protective and waterproof role for the first wire harness connector and the second wire harness connector. It relatively reduces the requirements for waterproof and sealing performance of the first wire harness connector and the second wire harness connector, eliminating the need to use waterproof connectors, thereby reducing costs, improving the neatness of the wire harness 200, improving the reliability of the connection between the first wire harness connector and the second wire harness connector, reducing structural complexity, and facilitating troubleshooting and maintenance.

[0056] In some embodiments of this utility model, reference is made to the appendix. Figure 2 and attached Figure 3 As shown, the housing 10 includes a body 1, a front cover 2, and a rear cover assembly 3. The body 1 is open on both sides along the front-rear direction. The front cover 2 is placed on the front side of the body 1, and a first through hole 21 is defined between the lower end of the front cover 2 and the lower end of the body 1. The rear cover assembly 3 is placed on the rear side of the body 1, and a second through hole 33 is provided on the rear cover assembly 3. By sealing the open openings on both sides of the body 1 along the front-rear direction by the front cover 2 and the rear cover assembly 3 respectively, the body 1, the front cover 2, and the rear cover assembly 3 can jointly define a receiving cavity. The separate design of the body 1, the front cover 2, and the rear cover assembly 3 allows the body 1, the front cover 2, and the rear cover assembly 3 to be processed separately and then connected, which facilitates the production and processing of the housing 10 and facilitates the placement and docking of the first wire harness connector and the second wire harness connector into the receiving cavity.

[0057] Further, see Appendix Figure 4As shown, the main body 1 has multiple partitions 14, including a first partition 141 and a second partition 142. The first partition 141 extends in the left-right direction, and the second partition 142 extends in the up-down direction. The first partition 141 and the second partition 142 are staggered, which can be used to divide the space inside the receiving cavity into multiple small compartments. The first wire harness connector can be inserted into the receiving cavity through the second through hole 33 and fixed in the small compartment. The second wire harness connector can be inserted into the receiving cavity through the first through hole 21 and directly plugged into the first wire harness connector. Optionally, the number and arrangement of the first partition 141 and the second partition 142 can be designed and adjusted according to the actual use to adapt to different types of wire harness connectors.

[0058] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 As shown, the rear cover assembly 3 includes a first rear cover 31 and a second rear cover 32. The first rear cover 31 is disposed on the rear side of the body 1 and connected to the body 1. The second rear cover 32 is detachably connected to the lower end of the first rear cover 31. The first rear cover 31 and the second rear cover 32 together define a second through hole 33. It can be understood that when assembling the first wire harness connector into the cable protection box 100, the first rear cover 31 is first fixed to the body 1, and then the first wire harness connector is passed through the second through hole 33 and fixed in the receiving cavity. After the wire harness 200 is arranged, the second rear cover 32 is assembled onto the first rear cover 31 from bottom to top, which facilitates the insertion of the first wire harness connector. It should be noted that the separate design of the first rear cover 31 and the second rear cover 32 allows for separate processing of the first rear cover 31 and the second rear cover 32 before connection, which facilitates the production and processing of the rear cover assembly 3 and makes it easier to place the first wire harness connector into the receiving cavity.

[0059] Preferably, refer to the appendix Figure 9 As shown, the upper side of the second rear cover 32 is provided with multiple reinforcing ribs 324. The multiple reinforcing ribs 324 are spaced apart in the left and right directions, which can increase the overall structural strength of the second rear cover 32 and ensure the reliability of the cable protection box 100.

[0060] In a further embodiment of this utility model, reference is made to the appendix. Figure 7 and attached Figure 9As shown, the rear surface of the first rear cover 31 has a first flange 311, and the rear surface of the second rear cover 32 has a second flange 321. Both the first flange 311 and the second flange 321 extend along the circumferential direction of the second through hole 33, and the first flange 311 and the second flange 321 together form a ring. The arrangement of the first flange 311 and the second flange 321 can guide and position the wire harness 200, ensuring the reliability and stability of the wire harness 200 fixation. Furthermore, after the wire harness 200 is installed, the first flange 311 is located on the upper side of the wire harness 200, which can provide a certain degree of rain protection for the wire harness 200, preventing short circuits, corrosion, damage, etc., and avoiding more serious situations such as burning and fire.

[0061] Further, see Appendix Figure 11 As shown, the first flange 311 is inclined downward in the direction from front to back. When rainwater, car wash water and other liquids drip onto the first flange 311, they can flow along the shape of the first flange 311 to the side away from the main body 1. This can prevent rainwater, car wash water and other liquids from entering the receiving cavity from above the wire protection box 100, avoid short circuits, corrosion and damage to the wire harness 200, and prevent more serious situations such as burning and fire, thus ensuring safety and reliability.

[0062] Furthermore, see the attached document. Figure 11 As shown, in the front-to-back direction, the length of the first flange 311 is greater than the length of the second flange 321. When rainwater, car wash water, or other liquids drip onto the first flange 311, they can flow along the first flange 311 to the side away from the main body 1. This prevents rainwater, car wash water, or other liquids from dripping from the first flange 311 onto the second flange 321, thereby preventing rainwater, car wash water, or other liquids from entering the receiving cavity. This prevents the wiring harness 200 from short-circuiting, corroding, or being damaged, and avoids more serious situations such as burning or fire, ensuring safety and reliability.

[0063] Optionally, refer to the appendix. Figure 9 As shown, a cable tie hole 325 is reserved on the second flange 321. When the wire harness 200 is not fixed as expected in the second through hole 33 (such as being easy to loosen and fall off, or moving around), a cable tie can be inserted into the cable tie hole 325 to lock the wire harness 200 a second time.

[0064] In a further embodiment of this utility model, reference is made to the appendix. Figure 7 and attached Figure 8As shown, a spring piece 331 is provided in the second through hole 33. The spring piece 331 is elastic and extends in an open ring along the circumferential direction of the second through hole 33, with the opening of the spring piece 331 facing downward. It can be understood that when the first wire harness connector is assembled into the cable protection box 100, the first wire harness connector is first passed through the second through hole 33 defined by the first rear cover 31 and fixed in the receiving cavity, and then the second rear cover 32 is assembled onto the first rear cover 31 from bottom to top. Therefore, preliminary positioning is required after the wire harness 200 is installed, otherwise it will affect the assembly of the second rear cover 32. The spring piece 331 can be used to pre-lock the rubber sleeve or other accessories on the wire harness 200 into the second through hole 33, which plays a pre-positioning role for the wire harness 200 and ensures the normal installation of the second rear cover 32.

[0065] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 and attached Figure 10 As shown, the cable protection box 100 also includes a through-hole accessory 20. The through-hole accessory 20 is disposed within the second through-hole 33 and sleeved on the wire harness 200. The through-hole accessory 20 has an open circular ring structure, which can be pre-installed on the wire harness 200. It is understood that due to factors such as different wire diameters of the wire harness 200 and different degrees of softness and hardness of the rubber sleeve used, the wire harness 200 may be in a movable state in the second through-hole 33. After the wire harness 200 is subjected to force, the rubber sleeve may come out of the second through-hole 33. By sleeved on the wire harness 200, the through-hole accessory 20 can be locked in the second through-hole 33 and cooperate with the spring piece 331, indirectly fixing the relative position of the wire harness 200 and the second through-hole 33, preventing the wire harness 200 from coming out of the second through-hole 33, and ensuring the reliability of the wire harness 200 and the first wire harness connector.

[0066] Optionally, the via fitting 20 can be designed as needed. By adjusting the structure of the inner wall of the via fitting 20, it can be adapted to various wire harness 200 sleeves, increasing the flexibility in actual use.

[0067] In a further embodiment of this utility model, reference is made to the appendix. Figure 7 and attached Figure 9 As shown, the first rear cover 31 and the second rear cover 32 are snapped together, which is simple to operate, easy to disassemble and assemble, reduces the difficulty of connecting the first rear cover 31 and the second rear cover 32, improves the assembly efficiency of the first rear cover 31 and the second rear cover 32, and reduces the assembly cost and maintenance cost of the cable protection box 100.

[0068] In a specific example, see Appendix Figure 7 and attached Figure 9As shown, the second rear cover 32 has a sliding groove 322 at both ends in the left-right direction, and the sliding groove 322 extends in the up-down direction. The outer wall surface of the sliding groove 322 has a protrusion 323. The first rear cover 31 has a slider 313 at both ends in the left-right direction. During the assembly of the first rear cover 31 and the second rear cover 32, the slider 313 slides from the upper end to the lower end of the sliding groove 322. The slider 313 is provided with a spring sheet structure, and the spring sheet structure has a positioning hole 314. When the first rear cover 31 and the second rear cover 32 are assembled in place, the protrusion 323 is engaged in the positioning hole 314 to realize the snap-fit ​​connection between the first rear cover 31 and the second rear cover 32.

[0069] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 As shown, the cable protection box 100 also includes a sealing ring 30. The sealing ring 30 is located between the front cover 2 and the body 1 and extends along the circumferential direction of the body 1. It can achieve a seal between the front cover 2 and the body 1, ensuring the airtightness of the cable protection box 100. This prevents rainwater, car wash water, and other liquids from flowing into the receiving cavity from the gap between the front cover 2 and the body 1, and prevents the wiring harness 200 from short-circuiting, corroding, or being damaged. It also prevents more serious situations such as burning and fire, ensuring the reliability of the cable protection box 100 and improving the safety performance of the vehicle.

[0070] It is understandable that the sealing ring 30 is located between the front cover 2 and the body 1. This could be achieved by having a third groove 23 on the side of the front cover 2 facing the body 1, extending along the circumferential direction of the front cover 2, with the sealing ring 30 located within the third groove 23 and directly abutting against the end face of the body 1 facing the front cover 2; or by having a fourth groove 15 on the side of the body 1 facing the front cover 2, extending along the circumferential direction of the body 1, with the sealing ring 30 located within the fourth groove 15 and directly abutting against the end face of the front cover 2 facing the body 1; or by having a third groove 23 and a fourth groove 15 on the sides of the front cover 2 and the body 1 facing each other, both extending along the circumferential direction of the body 1, with the sealing ring 30 located within both the third groove 23 and the fourth groove 15.

[0071] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6As shown, the main body 1 and the front cover 2 are connected by fasteners, which facilitates the disassembly and assembly of the main body 1 and the front cover 2, ensuring the reliability and stability of the cable protection box 100 assembly. Specifically, the side of the main body 1 facing the front cover 2 has multiple first mounting holes 11, which are spaced apart along the circumferential direction of the main body 1. The side of the front cover 2 facing the main body 1 has multiple second mounting holes 22, which are spaced apart along the circumferential direction of the front cover 2 and correspond one-to-one with the multiple first mounting holes 11. Fasteners pass through both the first mounting holes 11 and the second mounting holes 22 to connect the main body 1 and the front cover 2. Optionally, the fasteners are bolts.

[0072] Preferably, the plurality of first mounting holes 11 can be used in combination with round holes and oblong holes, which can reduce the accuracy requirements of the first mounting holes 11, reduce the assembly difficulty of the body 1 and the front cover 2, and facilitate the assembly of the cable protection box 100. Further, refer to the attached... Figure 4 As shown, a first steel sleeve 111 is embedded in the first mounting hole 11, and a second steel sleeve 221 is embedded in the second mounting hole 22, thereby strengthening the structure of the first mounting hole 11 and the second mounting hole 22 and preventing local damage when installing bolts.

[0073] Further, see Appendix Figure 3 Appendix Figure 4 and attached Figure 7 As shown, the main body 1 and the rear cover assembly 3 are snapped together, which is simple to operate, easy to disassemble and assemble, reduces the connection difficulty between the main body 1 and the rear cover assembly 3, improves the assembly efficiency of the main body 1 and the rear cover assembly 3, and reduces the assembly cost and maintenance cost of the cable protection box 100.

[0074] In a specific example, see Appendix Figure 4 and attached Figure 7 As shown, the outer peripheral wall of the main body 1 has eight slots 12, which are spaced apart along the circumferential direction of the main body 1. The outer peripheral wall of the first rear cover 31 has eight buckles 315, which are spaced apart along the circumferential direction of the first rear cover 31 and correspond one-to-one with the eight slots 12. Among them, three of the eight buckles 315 are located on the left side of the first rear cover 31, three are located on the right side of the first rear cover 31, and the remaining two are located on the upper side of the first rear cover 31.

[0075] In a further embodiment of this utility model, reference is made to the appendix. Figure 8As shown, one of the back cover assembly 3 and the body 1 has a first groove 312 and the other has a protrusion. The first groove 312 and the protrusion are respectively located on the side of the back cover assembly 3 and the body 1 facing each other. The first groove 312 extends along the circumferential direction of the back cover assembly 3, and the protrusion is disposed in the first groove 312 and extends along the circumferential direction of the body 1. Through the cooperation of the first groove 312 and the protrusion, a preliminary positioning function can be played when the back cover assembly 3 is assembled onto the body 1, which facilitates the installation of the back cover assembly 3 and the body 1.

[0076] It is understood that one of the back cover assembly 3 and the body 1 has a first groove 312 and the other has a protrusion. It is possible that the side of the back cover assembly 3 facing the body 1 has the first groove 312 and the side of the body 1 facing the back cover assembly 3 has the protrusion; or it is possible that the side of the back cover assembly 3 facing the body 1 has the protrusion and the side of the body 1 facing the back cover assembly 3 has the first groove 312. No further restrictions are imposed here.

[0077] In some embodiments of this utility model, reference is made to the appendix. Figure 6 As shown, a second groove 211 is provided on the inner wall of the first through hole 21. The second groove 211 extends along the circumferential direction of the first through hole 21. A rubber sleeve with a raised structure can be designed on the position of the wire harness 200 that mates with the first through hole 21. The mating of the second groove 211 and the rubber sleeve can ensure the installation and fixation of the wire harness 200, prevent the wire harness 200 from coming out of the first through hole 21, and ensure the reliability of the wire harness 200 and the second wire harness connector.

[0078] It should be noted that during the assembly of the cable protection box 100, firstly, the sealing ring 30 is inserted into the fourth groove 15 of the main body 1, the through hole accessory 20 is bundled onto the wire harness 200 in advance, and then the first wire harness connector is fixed in the receiving cavity. Subsequently, the first rear cover 31 is snapped onto the main body 1, and the first rear cover 31 is snapped onto the second rear cover 32. Then, the assembled main body 1, sealing ring 30, rear cover assembly 3 and through hole accessory 20 are fixed onto the bracket of the front engine compartment body. Then, the second wire harness connector is plugged into the already fixed first wire harness connector. Finally, the front cover 2 is screwed onto the main body 1 to complete the assembly of the cable protection box 100.

[0079] This utility model also proposes a vehicle having the cable protection box 100 described in the above embodiments.

[0080] like Figure 1 As shown, the vehicle according to this utility model embodiment includes a front engine compartment body and the aforementioned cable protection box 100.

[0081] Specifically, the front engine compartment body has a bracket, and the housing 10 is connected to the front engine compartment body by fasteners, which facilitates the disassembly and assembly of the cable protection box 100 and ensures the reliability and stability of the cable protection box 100 installation. (See attached reference.) Figure 4 As shown, the outer peripheral wall of the body 1 has multiple mounting lugs 13, which are spaced apart along the circumferential direction of the body 1. Each mounting lug 13 has a third mounting hole 131. Fasteners pass through the third mounting holes 131 to fix the housing 10 to the bracket, thereby fixing the housing 10 to the front engine compartment body. Optionally, the fastener is a bolt.

[0082] In a specific example, see Appendix Figure 4 As shown, the outer peripheral wall of the body 1 has four mounting lugs 13. Two of the four mounting lugs 13 are located on the left side of the body 1, and the other two are located on the right side of the body 1. The third mounting holes 131 on the two mounting lugs 13 located on the same side of the body 1 are a round hole and an oblong hole, respectively. By using the round hole and the oblong hole in combination, the accuracy requirement of the third mounting hole 131 can be reduced, the assembly difficulty of the cable protection box 100 can be reduced, and the installation of the cable protection box 100 can be facilitated. Further, refer to the attached... Figure 4 As shown, a third steel sleeve 132 is embedded in the third mounting hole 131, which can strengthen the structure of the third mounting hole 131 and prevent local damage when installing bolts.

[0083] Preferably, since the mounting lug 13 is the mounting point of the entire cable box 100 and needs to bear the weight of the entire cable box 100 and the wire harness 200, the structural strength of the mounting lug 13 can be improved by means of thickening the mounting lug 13 and reinforcing ribs 324.

[0084] In existing technologies, holes are typically drilled in the front bulkhead sheet metal of the vehicle body, and then the wiring box is directly installed on the front bulkhead sheet metal, with the wiring harness connector installed inside the wiring box. However, due to limitations in vehicle styling and component layout, many models cannot have large holes drilled in the body sheet metal to accommodate the wiring box, and drilling large holes also places higher demands on sealing and waterproofing. In contrast, this utility model uses fasteners to directly fix the wiring box 100 to the front engine compartment body, eliminating the need to drill large holes in the front bulkhead sheet metal. This makes assembly more convenient, layout more flexible, compatibility higher, and applicability stronger, allowing the wiring box 100 to be adapted to more vehicles. The wiring box 100 is expandable and platform-based, and it does not directly expose the components inside the front engine compartment after opening the vehicle's hood, resulting in better aesthetics and waterproofing.

[0085] According to the vehicle of this utility model embodiment, by providing the above-mentioned cable protection box 100, and by providing a first through hole 21 and a second through hole 33 on the housing 10, the first through hole 21 is provided at the lower end of the housing 10 and extends in the vertical direction, and the second through hole 33 is provided at the rear side of the housing 10 and extends in the front-rear direction, the waterproof performance of the cable protection box 100 can be effectively improved, the reliability of the cable protection box 100 can be guaranteed, and the safety performance can be improved. It also plays a protective and waterproof role for the first wire harness connector and the second wire harness connector, relatively reducing the requirements for waterproof and sealing performance of the first wire harness connector and the second wire harness connector, eliminating the need to use waterproof connectors, thereby reducing costs, improving the neatness of the wire harness 200, improving the reliability of the connection between the first wire harness connector and the second wire harness connector, reducing structural complexity, and facilitating troubleshooting and maintenance.

[0086] The wiring box 100 and other components and operations of the vehicle according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
