[0048] Please refer to Figures 1 to 7The utility model provides a safe escape side door lock catch, which comprises a base 10, an open lock ring 20, a lock rod 30, and an unlocking assembly 40. The base 10 is connected to a vehicle body. The first end 201 of the open lock ring 20 is fixedly connected to the base 10, and the second end 202 is connected to the base 10 to form a break 203 suitable for the passage of a lock tongue 60. The lock rod 30 is slidably arranged in the base 10 and is inserted into the second end 202 at one end. In the inserted state, the lock rod 30 and the open lock ring 20 form a closed lock hole 204 in the base 10. The unlocking assembly 40 is connected to an interior trim panel 70 of the vehicle door and has a pull wire 400 connected to the lock rod 30. The unlocking assembly 40 is used to drive the lock rod 30 to slide away from the second end 202 to open the break 203.

[0049] It should be noted that the open lock ring 20 in the embodiment can be a U-shaped structure with unequal lengths on both sides. The long side is fixedly connected to the base 10 by screwing or welding as the first end 201, and the end side is connected to the base 10 to form a break 203 as the second end 202. When the lock rod 30 is inserted into the second end 202 at the end, the break 203 is closed, thereby forming a closed lock hole 204 with the open lock ring 20. Under normal circumstances, the lock tongue 60 is extended to be inserted into the lock hole 204 to lock the vehicle door, and the lock tongue 60 is retracted to be pulled out of the lock hole 204 to unlock the vehicle door. When the vehicle door lock control fails and the lock tongue 60 cannot be actuated, the unlocking assembly 40 installed on the interior trim panel 70 of the vehicle door can be operated by the driver or passenger in the vehicle to pull the lock rod 30 away from the second end 202 through the pull wire 400 to open the break 203. At this time, when the vehicle door is opened, the lock tongue 60 is separated from the lock hole 204 through the break 203, thereby achieving emergency unlocking of the vehicle door.

[0050] It should be understood that the insertion and cooperation of the lock rod 30 and the second end 202 can improve the structural stability of the lock hole 204, avoid the bending and deformation of the lock rod 30 caused by the collision of the lock tongue 60 with the lock rod 30 under normal use conditions, and further prevent the vehicle door from being reliably locked. In addition, the lock rod 30 can be based on overall extension and retraction to close or open the break 203, or can be a two-segment hinged structure. One segment is in sliding cooperation with the base 10 and connected to the pull wire 400, and the other segment is in insertion cooperation with the second end 202. When the pull wire 400 pulls the lock rod 30 to move away from the second end 202, the hinged segment can freely swing. At this time, when the vehicle door is opened, the segment swings outward of the lock hole 204 under the pressing action of the lock tongue 60 to open the break 203, so that the lock tongue 60 is separated from the lock hole 204 to unlock the vehicle door.

[0051] Compared with the prior art, the safety escape side door lock catch provided by the embodiment utilizes the break 203 formed by the open lock ring 20 and suitable for the bolt 60 to pass through. Normally, the lock rod 30 is inserted into the second end 202 of the open lock ring 20 to close the break 203 and form the lock hole 204, at this time, the lock hole 204 and the bolt 60 normally cooperate to realize the door locking function. When the bolt 60 cannot act in an emergency, the unlocking assembly 40 installed on the vehicle door inner panel 70 can be operated to drive the pull wire 400 to move the lock rod 30, so that the lock rod 30 is separated from the second end 202 of the open lock ring 20 to open the break 203, so that the bolt 60 can pass through the break 203 to separate from the open lock ring 20 to realize unlocking. Compared with the prior art, the mode of driving the bolt 60 to move to realize emergency unlocking is more simple and compact, without the need to change the structure of the bolt, and is not limited by the complex structure and narrow space inside the side door. Therefore, the unlocking assembly 40 can be arranged on each side door of the vehicle. In a crisis situation where the side door cannot be opened, the driver or passenger can operate the unlocking assembly 40 to unlock the corresponding side door in the first time to escape from the vehicle, avoid delaying the escape opportunity, and thus improve the safety of the vehicle.

[0052] In some embodiments, referring to Figures 3 to 5 , the lock rod 30 includes a sliding section 31 and a swinging section 32. The sliding section 31 is slidably arranged in the base 10 and connected with the pull wire 400. One end of the swinging section 32 is hinged to the end of the sliding section 31 facing the break 203, and the other end is inserted into the second end 202. The sliding section 31 drives the swinging section 32 to separate from the second end 202 under the traction of the pull wire 400, so that the swinging section 32 has the freedom to swing to open the break 203.

[0053] When the bolt 60 cannot act and needs to be opened in an emergency, the driver or passenger in the vehicle operates the unlocking assembly 40 to drive the pull wire 400 to slide the sliding section 31 away from the second end 202, so that the swinging section 32 separates from the second end 202, and the swinging section 32 can freely swing around the hinge axis. During the process of opening the door, the bolt 60 collides with the swinging section 32 to make the swinging section 32 swing outward of the lock hole 204, so that the bolt 60 can move to the outside of the lock hole 204 through the break 203 to realize unlocking. Thus, the movement distance of the lock rod 30 can be greatly shortened during emergency unlocking, so as to reduce the requirement of the lock rod 30 for the movement space and improve the compactness of the structure.

[0054] In some possible implementations, referring to Figures 3 to 5 , the side of the base 10 away from the open lock ring 20 is provided with a sliding sleeve 11, and the sliding sleeve 11 is sleeved on the sliding section 31. The sliding sleeve 11 is provided with a first elastic member 12 inside, the first elastic member 12 is connected with the sliding section 31, and the first elastic member 12 is used to push the sliding section 31 to keep the swinging section 32 in the inserted state with the second end 202.

[0055] The connection reliability of the sliding section 31 can be improved by setting the sliding sleeve 11, and the first elastic member 12 such as a spring is arranged in the sliding sleeve 11 to form an elastic thrust force on the sliding section 31, the elastic thrust force is transmitted to the swinging section 32 to keep the swinging section 32 and the second end 202 in a reliable plug-in state, thereby improving the structural stability of the lock hole 204 in the normal use state.

[0056] It should be noted that, referring to Figure 4 and Figure 5 , the second end 202 is provided with a plug hole 205, the end face of the swinging section 32 facing the second end 202 is provided with a plug pin 321, the plug pin 321 is plug-in matched with the plug hole 205; the sliding section 31 is provided with a first stop ring 311 and a second stop ring 312 on both sides of the base 10, the sliding section 31 keeps the first stop ring 311 in abutment with the base 10 under the elastic force of the first elastic member 12, at this time the plug pin 321 is plugged into the plug hole 205, when the pull wire 400 overcomes the elastic force of the first elastic member 12 to move the sliding section 31 to the state that the second stop ring 312 is in abutment with the base 10, the plug pin 321 is disengaged from the plug hole 205.

[0057] In some embodiments, as shown in Figure 3 , the sliding sleeve 11 is connected with a pull rod mechanism 50, the pull wire 400 is connected with the sliding section 31 through the pull rod mechanism 50; wherein the pull rod mechanism 50 is used to guide the pull wire 400 to form an axial traction force on the sliding section 31.

[0058] Since the pull wire 400 is a flexible wire, and considering that the layout position of the unlocking assembly 40 on the door trim 70 needs to deviate from the slide rod, the pull wire 400 cannot form a direct axial force on the sliding section 31 when it is directly connected with the sliding section 31, which may cause the movement of the sliding section 31 by the pull wire 400 to be blocked. In order to avoid this situation, a pull rod structure is arranged between the sliding section 31 and the pull wire 400, and the pull rod mechanism 50 is used to guide the direction of the traction force of the pull wire 400 to an angle consistent with the axial direction of the sliding section 31, thereby improving the stability of the movement of the sliding section 31 by the pull wire 400.

[0059] As a specific embodiment of the above-mentioned pull rod mechanism 50, please refer to Figure 6 , the pull rod mechanism 50 includes a pull rod housing 51 and a pull rod shaft 52; wherein one side inner wall of the pull rod housing 51 is provided with a connecting sleeve 511, one end of the connecting sleeve 511 is sleeved on the sliding sleeve 11, and the other end forms a sliding hole 512, the other side inner wall of the pull rod housing 51 is provided with a guide hole 513 suitable for the pull wire 400 to pass through, and the guide hole 513 is aligned with the connecting sleeve 511; the pull rod shaft 52 is slidably arranged in the sliding hole 512, one end of the pull rod shaft 52 is connected with the sliding section 31, and the other end is connected with the pull wire 400.

[0060] The connecting sleeve 511 can be integrally formed on the side wall of the pull rod housing 51, and is fixed to the sliding sleeve 11 through the inner hole at one end of the connecting sleeve 511 as a mounting hole. The other end of the connecting sleeve 511 forms a sliding hole 512 with a smaller diameter than the mounting hole. The pull rod shaft 52 is in sliding fit with the sliding hole 512 and is pinned or screwed with the sliding section 31. The pull rod shaft 52 can also be regarded as an axial extension of the sliding section 31. The pull wire 400 is connected to the pull rod housing 51 and the pull rod shaft 52 under the guidance of the guide hole 513. In order to ensure that the pulling force of the pull wire 400 can drive the pull rod shaft 52 to move axially, a gap is provided between the end of the pull rod shaft 52 away from the sliding section 31 and the inner wall of the guide hole 513 of the pull rod housing 51. Thus, the pull wire 400 forms an angle consistent with the axial direction of the pull rod shaft 52 after passing through the guide hole 513, thereby ensuring the reliability and stability of the pull wire 400 in driving the pull rod shaft 52 to move, and further improving the stability of the pull rod shaft 52 in driving the sliding section 31 to move so that the swing section 32 is separated from the second end 202.

[0061] For example, referring to Figure 6 The end of the pull rod shaft 52 towards the sliding section 31 is provided with a slot 521, and the slot walls on both sides of the slot 521 are provided with spherical protrusions 522. The end of the sliding section 31 towards the pull rod shaft 52 is formed with a plug 313, and the side wall of the plug 313 is provided with a clamping hole 314. The plug 313 is inserted into the slot 521, and the spherical protrusions 522 are embedded in the clamping hole 314.

[0062] The pull rod shaft 52 and the sliding section 31 are connected by plug-in fit, which facilitates disassembly and assembly. The clamping fit of the spherical protrusions 522 and the clamping hole 314 can improve the plug-in reliability of the slot 521 and the plug 313. During installation, the pull rod shaft 52 is slid to a position outside the sliding hole 512, and then the plug 313 is inserted into the slot 521. After plug-in, the pull rod shaft 52 is slid to the port of the sliding hole 512 or inside the sliding hole 512. The inner wall of the sliding hole 512 can constrain the pull rod shaft 52 to prevent the slot 521 from opening under stress and causing the plug 313 to fall out of the slot 521. This not only facilitates disassembly and assembly, but also ensures the reliability of the connection.

[0064] The sliding cylinder 411 can be integrally formed in the unlocking housing 41, and the unlocking housing 41 is hiddenly installed on the inner surface of the door inner panel 70; the operating pull rod 42 is in sliding fit with the sliding cylinder 411 and penetrates the door inner panel 70 to be hingedly connected with the pull ring 421; when the pull ring 421 is pulled by the driver or passenger in the vehicle, the operating pull rod 42 moves axially to make the pull wire 400 obtain traction, so that the pull wire 400 drives the lock rod 30 to open the fracture 203 to unlock the door, which is simple and labor-saving; the unlocking housing 41 is hiddenly arranged on the surface of the door inner panel 70 facing the outside of the vehicle, and the pull ring 421 is hidden by the recess on the decorative cover 414, so that the unlocking housing 41 is not exposed to affect the appearance of the interior decoration; after the pull ring 421 is turned and hidden in the recess, the pull ring 421 can be clamped with the mouth of the recess, so that the pull ring 421 can not freely slide to produce abnormal sound, and the pull ring is not exposed to ensure the appearance of the door inner panel 70.

[0065] It should be understood that, please refer to Figure 7 In this embodiment, the unlocking housing 41 is provided with a through hole 412 suitable for the pull wire 400 to penetrate; at least two wire guide shafts 413 are arranged on the same side of the operating pull rod 42 in the unlocking housing 41, and one of the wire guide shafts 413 is aligned with the through hole 412; the pull wire 400 penetrates the through hole 412 and is sequentially wound around each wire guide shaft 413 to be connected with the operating pull rod 42.

[0066] Since the pull wire 400 needs to be connected with the lock rod 30 deviating from the axial direction of the operating pull rod 42, at least two wire guide shafts 413 are arranged in the unlocking housing 41 to bend and guide the pull wire 400, so that the axial movement of the operating pull rod 42 can form stable traction on the pull wire 400, and then the pull ring 421 can be pulled to drive the lock rod 30 to move through the pull wire 400, thereby improving the operation convenience and stability.

[0067] The guide shaft 413 can be a fixed shaft, and the pull wire 400 directly slides along the peripheral wall of the guide shaft 413 when the operating pull rod 42 moves; or the guide shaft 413 can be rotationally connected in the unlocking housing 41, and when the operating pull rod 42 moves, the pull wire 400 moves around the guide shaft 413 to drive the guide shaft 413 to passively rotate, thereby reducing the sliding abrasion of the guide shaft 413 to the pull wire 400; in addition, in order to improve the connection stability of the pull wire 400 on the guide shaft 413, the peripheral wall of the guide shaft 413 is provided with a ring groove suitable for embedding the pull wire 400.

[0068] Specifically, referring to Figure 7 In the embodiment, the part of the operating pull rod 42 extending out of the sliding cylinder 411 is provided with a limiting ring 422, and a second elastic member 43 is sleeved on the operating pull rod 42, and the second elastic member 43 is located between the limiting ring 422 and the inner wall of the unlocking housing 41, and is used for elastically pushing the limiting ring 422 to make the limiting ring 422 abut against the end of the sliding cylinder 411.

[0069] The second elastic member 43 can be a spring, which pushes the limiting ring 422 to make the limiting ring 422 abut against the end of the sliding cylinder 411 reliably, thereby avoiding the axial movement of the operating pull rod 42 during the driving of the vehicle; when it is necessary to urgently unlock the door, the driver in the vehicle only needs to pull the pull ring 421 to overcome the elastic force of the second elastic member 43 and drive the operating pull rod 42 to move axially, so that the pull wire 400 obtains traction to drive the locking rod 30 to move away from the second end 202, and after the unlocking is completed, the pull ring 421 is released to make the operating pull rod 42 automatically reset under the elastic force of the second elastic member 43, thereby improving the operation convenience.

[0070] Based on the same inventive concept, in combination with Figures 1 to 7 It is understood that the embodiments of the present application also provide a vehicle comprising the above-mentioned safety escape side door lock catch.
