Description

Technical Field

[0001] This application belongs to the field of automotive body opening and closing technology, and specifically relates to a top and bottom door lock system with an emergency inward opening mechanism. Background Technology

[0002] Currently, most mainstream vehicles on the market with a trunk lid-top door feature a structure where the top door is the main door and the bottom door is the ballast door. These lid-top doors, referencing traditional SUV designs, typically include an emergency inward-opening lever. This is achieved by using the lock body's self-locking mechanism to disengage the lever and unlocking lever, along with an additional lever and push plate on the door panel. This design has a generally accepted value.

[0003] However, for a multi-purpose vehicle that has both a ground door and a pickup truck function, since the multi-purpose vehicle has both pickup truck and SUV functions, the ground door itself is a limiting condition for the main door (i.e., the ground door presses down on the ground door). Therefore, the rear compartment needs an emergency inward opening mechanism for the ground door to function as the main door, so that the ground door can realize emergency escape and maintenance functions.

[0004] Therefore, this application provides a top and bottom door lock system with an emergency inward opening mechanism. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] A top-and-bottom door lock system with an emergency inward opening mechanism includes a first emergency inward opening mechanism 1 for the top-and-bottom door system. The first emergency inward opening mechanism 1 includes a side panel assembly 11, a rear inner panel 12, a sill trim 13, a bottom door lock assembly 14, a bottom door lock buckle plate 15, and a double-lock cable assembly. The rear inner panel 12 is mounted on the side panel assembly 11. The sill trim 13 is mounted on the rear inner panel 12. Bottom door lock buckles 15 and bottom door lock assemblies 14 are mounted on both the driver's and passenger's sides of the side panel assembly 11, and are connected by a locking mechanism. The two ends of the double-lock cable assembly are respectively connected to the bottom door lock assemblies 14 on the driver's and passenger's sides of the side panel assembly 11. The double-lock cable assembly includes a first cable sleeve 3, a second cable sleeve 31, a third cable sleeve 32, and a first core wire 33. The second core wire 34, the third core wire 35, and the junction box assembly 36; the junction box assembly 36 is installed on the driver's side of the side panel assembly 11; one end of the junction box assembly 36 is connected to the first pull cable sleeve 3 via the main sleeve 51, and the other end of the junction box assembly 36 is connected to the second pull cable sleeve 31 and the third pull cable sleeve 32 via a pair of separate sleeves 56 respectively; a set of first buckles 37 and a set of second buckles 38 are installed on the side panel assembly 11 and the rear inner panel 12; lock body locking connectors 43 are installed on the ground door lock assemblies 14 on the driver's side and passenger side of the side panel assembly 11; waterproof corrugated pipes 44 are connected to the ends of the second pull cable sleeves 31 and the third pull cable sleeves 32 away from the junction box assembly 36 via lock body locking connectors 43; a die-cast ring 45 is fixed to the end of the waterproof corrugated pipe 44, such as Figure 17As shown; an L-shaped connector bracket 4 is installed on the driver's side of the side panel assembly 11; a sheath connector 41 is fixedly connected to the end of the first cable sleeve 3 away from the junction box assembly 36, and the sheath connector 41 is inserted into the opening of the L-shaped connector bracket 4 through an annular groove 42; an opening and closing plate 47 is installed on the driver's side of the side panel assembly 11; the first core wire 33 is interconnected with the second core wire 34 and the third core wire 35 through the junction box assembly 36; the first core wire One end of the first core wire 33 is fixedly connected to a pull ring 46, which is engaged with the anti-detachment ring of the opening and closing plate 47. The other end of the first core wire 33 passes through the sheath connector 41 and the first pull cable sleeve 3 and enters the junction box assembly 36. One end of the second core wire 34 enters the junction box assembly 36, and the other end of the second core wire 34 enters the second pull cable sleeve 31, then passes out of the second pull cable sleeve 31 and is inserted into the lock body connector 43 and the waterproof corrugated tube 44 before connecting with the die-cast ring 45. The die-cast ring 45 is connected to the switch of the ground door lock assembly 14 on the driver's side of the side panel assembly 11; one end of the third core wire 35 enters the junction box assembly 36, and the other end of the third core wire 35 enters the third pull cable sleeve 32, then passes through the third pull cable sleeve 32 and is inserted into the lock body clip connector 43 and the waterproof corrugated tube 44 before connecting with the die-cast ring 45. At the same time, the die-cast ring 45 is connected to the switch of the ground door lock assembly 14 on the passenger side of the side panel assembly 11; the L-shaped connector bracket 4 is made of SAPH440 with a thickness of 1.9-2.1mm; the sheath connector 41 is made of NBR; the first pull cable sleeve 3, the second pull cable sleeve 31, and the third pull cable sleeve 32 are all plastic-coated metal sheaths, with the middle metal material being SWRH62A and the plastic coating materials at both ends being PP and PE; the die-cast ring 45 is made of ZAMARK3; the waterproof corrugated tube 44 is made of EPDM. like Figure 1-7As shown in Figures 8 and 9, the first emergency inward opening mechanism 1 of the first ground door system is a lock system structure where the double-lock cable assemblies converge on the driver's side of the side panel assembly 11. In the first emergency inward opening mechanism 1 of the first ground door system, the junction box assembly 36 is installed on the driver's side of the side panel assembly 11. In case of emergency operation, the opening plate 47 can be opened directly, which drives the pull ring 46 to move. The pull ring 46 drives the first core wire 33 to tighten, and then drives the second core wire 34 and the third core wire 35 to tighten through the junction box assembly 36, thereby driving the ground door lock assemblies 14 on the driver's side and passenger side of the side panel assembly 11 to open, thus realizing emergency escape and maintenance functions. The first buckle 37 and the second buckle 38 can restrict and fix the second pull cable sleeve 31 and the third pull cable sleeve 32, which facilitates the second core wire 34 and the third core wire 35 in a predetermined position. The track is tightened, and because the sheath connector 41 is placed at the opening of the L-shaped connector bracket 4 through the annular groove 42, an interference fit is made to ensure the pull-out force of the sheath connector 41 and the L-shaped connector bracket 4. The tensile force of the first core wire 33 acts on the sheath connector 41 and the L-shaped connector bracket 4, effectively ensuring the tensile strength of the first core wire 33; the pull length at the pull ring 46 has a 30mm margin (it should not be too long, to avoid shaking and abnormal noise during the comprehensive road test of the whole vehicle), to avoid the tensile strength being concentrated on the anti-detachment ring after opening the opening and closing plate 47. After opening the opening and closing plate 47, the double lock can be opened directly with the pull ring 46. The anti-detachment ring at the lower end of the opening and closing plate 47 can ensure that the opening and closing plate 47 will not come off during the rotation process; the interference of the anti-detachment ring of the pull ring 46 and the opening and closing plate 47 is 0.5mm, ensuring that there will be no shaking or abnormal noise during the comprehensive road test of the whole vehicle; Figure 15 As shown, the L-shaped connector bracket 4 is made of SAPH440, which can withstand a tensile strength of 1000N and ensure waterproof sealing. Figure 16 As shown, the sheath connector 41 is an NBR, which has good static sealing performance; as Figure 18 As shown, the waterproof corrugated pipe 44 effectively prevents water from entering when the lock body connector 43 is facing upwards. Meanwhile, the die-cast ring 45 is made of ZAMARK material and is integrated with the waterproof corrugated pipe 44. The waterproof corrugated pipe 44 is plastic-coated on the die-cast ring 45 or installed as a single piece on the die-cast ring 45. The design interference between the waterproof corrugated pipe 44 and the die-cast ring 45 is 0.5mm on each side, ensuring waterproofing at the die-cast ring 45.

[0023] like Figure 22-27As shown, the junction box assembly 36 includes a bottom box 55 and a top box 5; a pair of split sleeves 56 are fixedly connected to the bottom end of the bottom box 55; a main sleeve 51 is fixedly connected to the top end of the top box 5; snap-fit ​​holes 57 are provided on the two side walls of the bottom box 55; oblique snap blocks 52 are fixedly connected to the two outer side walls of the top box 5; a sealing ring 54 is fitted onto the outer side wall of the top box 5 through an annular groove 53; a wire-jointing slider 6 slides through the gap in the inner wall of the top box 5; the top end of the wire-jointing slider 6 has a symmetrically distributed first upper circular groove 61 and second upper circular groove 64, and one side of the first upper circular groove 61 and second upper circular groove 64 is in a notch state; the bottom end of the wire-jointing slider 6 has a symmetrically distributed first lower circular groove 62 and second lower circular groove 65, and one side of the first lower circular groove 62 and second lower circular groove 65 is in a notch state; the first upper circular groove 61 and second upper circular groove 64 and the first lower circular groove 62 and second lower circular groove 65 are respectively... The upper and lower circular grooves are interconnected; the diameters of the first upper circular groove 61 and the second upper circular groove 64 are larger than the diameters of the first lower circular groove 62 and the second lower circular groove 65; the first cylindrical block 63 and the second cylindrical block 66 slide in the first upper circular groove 61 and the second upper circular groove 64 respectively; the second core wire 34 enters the first upper circular groove 61 through the sleeve 56 and the first lower circular groove 62 and is connected to the bottom end of the first cylindrical block 63; the third core wire 35 enters the second lower circular groove 65 through the sleeve 56 and the second lower circular groove 65 and is connected to the bottom end of the second cylindrical block 66; the bottom end of the wire combining slider 6 is provided with a first through hole 67, and the cross-section of the first through hole 67 is inverted T-shaped, and the third cylindrical block 68 slides in the lower wide hole of the first through hole 67; the first core wire 33 enters the lower narrow hole of the first through hole 67 through the main sleeve 51 and the upper narrow hole of the first through hole 67 and is connected to the top end of the third cylindrical block 68. During operation, one end of the second core wire 34 enters the bottom box 55 through a sleeve 56, and then the end of the second core wire 34 is fixed to the first cylindrical block 63. The first cylindrical block 63 is placed in the first upper circular groove 61 of the wire-joining slider 6, and the second core wire 34 is placed in the first lower circular groove 62. Similarly, one end of the third core wire 35 enters the bottom box 55 through another sleeve 56, and then the end of the third core wire 35 is fixed to the second cylindrical block 66. The second cylindrical block 66 is placed in the second upper circular groove 64 of the wire-joining slider 6, and the third core wire 35 is placed in the second lower circular groove 65. At the same time, the first core wire 34... 3. The wire enters the top box 5 through the main sleeve 51, and the first core wire 33 enters the lower wide hole of the first through hole 67 and is fixed to the third cylindrical block 68. At the same time, the wire combining slider 6 slides in the top box 5, and the sealing ring 54 is fitted in the annular groove 53 of the top box 5. Then, the top box 5 is inserted into the bottom box 55, and the inclined buckle 52 is inserted into the buckle hole 57, thereby completing the assembly of the junction box assembly 36. At the same time, the first core wire 33 can drive the wire combining slider 6 to drive the second core wire 34 and the third core wire 35 to move synchronously, thus completing the synchronous drive of the double lock. Meanwhile, the sealing ring 54 can play a waterproof role.

[0024] The second pull cable sleeve 31 and the third pull cable sleeve 32 are both fitted with a sponge tube 48 on the outside of the arc-shaped turning point when they are installed by a set of first buckles 37 and a set of second buckles 38; the sponge tube 48 is made of thermoplastic elastomer. The sponge tube 48 is made of PU, a thermoplastic elastomer, which can ensure that the first pull cable sleeve 3 and the second pull cable sleeve 31 are not contaminated during the wire threading process, and at the same time protect the first pull cable sleeve 3, the second pull cable sleeve 31 and the sheet metal of the side assembly 11 from being scratched.

[0025] The second emergency inward opening mechanism 2 of the second underground door system replaces the first emergency inward opening mechanism 1 of the first underground door system; the difference between the second emergency inward opening mechanism 2 of the second underground door system and the first emergency inward opening mechanism 1 of the first underground door system is that: the junction box assembly 36 is installed on the middle side wall of the rear inner panel 12, the top of the door sill trim 13 is connected to the cover plate 21 by a buckle, the sleeve connector 41 is installed on the inner side of the rear inner panel 12, and the top of the pull ring 46 is installed on the anti-detachment buckle of the cover plate 21; like Figure 10-14 As shown, the second day's emergency inward opening mechanism 2 of the ground door system is a lock system structure where the double-lock cable assembly converges at the rear floor. The core point is that the junction box assembly 36 is installed on the sheet metal of the rear inner panel 12. When an emergency opening is needed, the cover plate 21 is opened, and then the pull ring 46 is driven to open the switch components of the ground door lock assembly 14 on the driver's side and passenger side of the side panel assembly 11, thereby completing the emergency escape or maintenance function. At the same time, the junction box assembly 36 is fixed to the rear inner panel 12 by a buckle, and the sheath connector 4... 1. Fixed to the inside of the rear inner panel 12, the first pull cable sleeve 3 passes through the weight reduction hole of the rear inner panel 12 and emerges from the inside of the rear inner panel 12. Compared with the double lock pull cable assembly converging at the driver's side position of the side panel assembly 11, it reduces one protective sleeve connector 41 bracket; the pull ring 46 is through the sill trim 13 and the addition of an emergency inward opening cover 21, so that the cover 21 is engaged with the pull ring 46 through the anti-detachment locking ring. When the user operates, he directly lifts the cover 21 and drags the pull ring 46, and achieves synchronous unlocking through the double lock pull cable and the positioning locking point.

[0026] The internally designed emergency internally opening pull line assembly structure has two design forms: the double lock meeting point is in the side panel assembly 11 or the rear panel floor. That is, the first emergency internally opening mechanism 1 of the first ground door system and the second emergency internally opening mechanism 2 of the second ground door system. The selection is based on the actual lock system peripheral components.

[0027] like Figure 19-21As shown, the locking mechanism includes a locking mounting base plate 8 and a curved locking post 81; the curved locking post 81 is U-shaped, and both ends of the curved locking post 81 are riveted to the locking mounting base plate 8; the locking mounting base plate 8 is mounted on the door lock plate 15; the end of the curved locking post 81 away from the locking mounting base plate 8 is locked onto the door lock assembly 14; the locking mounting base plate 8 has X-axis and Z-axis adjustment scale lines 82; the U-shaped post of the curved locking post 81 has four or five bends; the locking mounting base plate 8 is made of SAPH440 or S355MC; the material of the curved locking post 81 is SCM435, the center distance of the curved locking post 81 is 21.5-22.5mm, and the diameter of the curved locking post 81 is 7.4-7.6mm; The latch mounting base plate 8 is made of SAPH440 or S355MC, and the bent lock pin 81 is made of SCM435. The center distance of the bent lock pin 81 is 21.5-22.5mm, and the diameter of the bent lock pin 81 is 7.4-7.6mm. The "U"-shaped body of the bent lock pin 81 has four or five bends. Both of these designs can meet the national standard's requirement of 1x lock pin load strength. Among them, the bent lock pin 81 with four bends has stronger latch load strength, but its disadvantage is that it cannot support most lock bodies, lock body sleeves, and lock pins. With a small gap (not meeting the 6mm gap requirement), the five-bend structure of the curved lock pin 81 can accommodate most lock bodies while meeting the national standard of 1 times the load strength, ensuring that the gap between the lock body sleeve and the lock pin is greater than 6mm. The connection between the curved lock pin 81 and the lock mounting base plate 8 is a press-fit connection, and the load strength of the curved lock pin 81 in the XYZ directions is ensured by the riveting height and riveting width.
