Description

Technical Field

[0001] The present invention belongs to the technical field of door locks, and in particular relates to a door lock structure with self-priming and ice-breaking functions. Background Art

[0002] Cars are a means of transportation that people often use in their lives. In order to make customers more comfortable and convenient when using them and enhance their experience, it is particularly important to unlock electronic control switches and improve the mechanical structure to achieve convenient switching.

[0003] Most common vehicle doors in the automotive industry currently feature self-priming and ice-breaking functions, but the structures implementing these functions are often complex and unstable. For example, in a new side door lock transmission mechanism with electric opening, self-priming, and ice-breaking functions, Chinese patent No. CN202210805006.0 primarily uses an actuator to impart rotational force to a transmission gear. This gear's rotation drives the self-priming lever body to achieve self-priming and ice-breaking functions. However, it is clear from this process that the actuator needs to send a signal indicating forward or reverse rotation of the transmission gear (i.e., clockwise or counterclockwise rotation of gear 14) to drive the self-priming lever body to achieve self-priming or ice-breaking functions accordingly. Furthermore, the directions of rotation of the self-priming lever during self-priming and ice-breaking are exactly opposite. This structure requires the actuator to send different signals and use the self-priming lever to move in two directions to achieve different functions. Therefore, if the actuator receives an erroneous signal, the mechanism will not function properly, affecting the door's self-priming and ice-breaking functions and reducing the user experience. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: to propose a method in which the drive assembly rotates along the direction of the transmission assembly, so that the transmission assembly can realize the switching of the vehicle door from a semi-locked state to a fully locked state. The release assembly can also be used to push the transmission assembly through the ice-breaking rod during the rotation process to make it switch from a fully locked state to a semi-locked state, thereby completing the ice-breaking function of the vehicle door. Therefore, the drive assembly only needs one signal and moves in the same direction to realize the self-priming and ice-breaking functions of the vehicle door, thereby improving the stability of the vehicle door function and the customer experience of the door lock structure with self-priming and ice-breaking functions.

[0005] The technical solution adopted by the present invention to solve the technical problem is to propose a door lock structure with self-priming and ice-breaking functions, comprising: a mounting plate for mounting components;

[0027] In the above-mentioned door lock structure with self-priming and ice-breaking functions, an ice-breaking rod rivet is provided at one end of the ice-breaking rod away from the self-priming connecting rod, and a guide groove is provided on the base.

[0028] In the above-mentioned door lock structure with self-priming and ice-breaking functions, the interruption rod further includes:

[0029] A support surface and a disengagement surface, wherein the support surface is connected to the disengagement surface and is arranged at an angle thereto, the support surface is used to abut against the ice-breaking rod rivet, and the disengagement surface is used to disengage from the ice-breaking rod rivet, so that the ice-breaking rod rivet is located on the guide groove;

[0034] The induction switch is arranged on the bottom plate. The unlocking link is provided with an arc surface, which movably abuts against the induction switch and detects the rotation position of the pawl through the induction switch.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] (1) The present invention provides a door lock structure with self-priming and ice-breaking functions through a transmission component with a semi-locked state and a fully locked state. When the release component is in the first position, the release component is used to abut against the ice-breaking rod of the drive component, so that the ice-breaking rod and the transmission component are staggered. At this time, when the drive component is used to move for the first time along the direction of the transmission component, the drive component can drive the ice-breaking rod to move to the top of the transmission component, and the self-priming push rod on the drive component pushes the transmission component to rotate from the semi-locked state to the fully locked state, thereby realizing the self-priming function of the car door; when the release component is rotated to the second position, the release component no longer abuts against the ice-breaking rod, and also pushes the self-priming push rod away from the transmission component, that is, achieving the purpose of staggering, thereby making the door lock have a self-priming function; When the ice-breaking rod is breaking the ice, the self-priming push rod no longer applies thrust to the transmission assembly. At this time, the ice-breaking rod is located on the rotation path of the transmission assembly. Therefore, when the driving assembly moves for the second time along the direction of the transmission assembly, the driving assembly can drive the ice-breaking rod to push the transmission assembly from a fully locked state to a semi-locked state during the movement, thereby realizing the ice-breaking function. The driving assembly in this door lock structure only requires a rotation direction signal, and the self-priming push rod and the ice-breaking rod move along the same side during the process of completing self-priming and ice-breaking respectively, avoiding the phenomenon that the self-priming and ice-breaking functions cannot be realized normally due to erroneous signal transmission of the external actuator, ensuring the overall stability of the door lock structure, and improving the user experience.

[0037] (2) The snow load link is located between the base plate and the cover plate and is used to limit the pawl from approaching the lock tongue. That is, when the pawl is away from the lock tongue, the lock tongue is in the unlocked state. However, due to the cold weather and other reasons, the lock tongue is frozen and cannot be rotated from the fully locked state to the half-locked state to realize the door opening function. At this time, the snow load link limits the position of the pawl, ensuring that when the subsequent drive component breaks the ice by rotating the lock tongue through the ice-breaking rod, the pawl no longer limits the lock tongue, thereby ensuring that the door is smoothly opened when it is switched from the fully locked state to the half-locked state after the ice-breaking rod breaks the ice.

[0038] (3) The interruption rod is provided with a support surface and a disengagement surface. When the ice-breaking rod rivet on the ice-breaking rod is located on the support surface, the ice-breaking rod rivet is located between the support surface and the upper end surface of the guide groove, so that the ice-breaking rod is located above the lock tongue, achieving the purpose of staggered arrangement, ensuring that the driving component smoothly completes the lock tongue from half-locked to fully locked state through the self-priming push rod, and when the disengagement surface disengages from the ice-breaking rod rivet, the ice-breaking rod rivet is located in the guide groove. When the driving component drives the ice-breaking rod to move, the ice-breaking rod can rely on the ice-breaking rod rivet to move along the direction of the guide groove and push the lock tongue from fully locked to half-locked state, completing the ice-breaking function.

[0052] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0053] like Figures 1 to 6As shown, the present invention provides a door lock structure with self-priming and ice-breaking functions, comprising: a mounting plate 1 for mounting parts; a transmission assembly 2 rotatably arranged on the mounting plate 1, the transmission assembly 2 having a semi-locked state and a fully locked state; a driving assembly 3, which is hinged on the mounting plate 1 and movably arranged on one side of the transmission assembly 2, and a self-priming push rod 30 and an ice-breaking rod 31 that move synchronously are hinged on the driving assembly 3, the self-priming push rod 30 and the ice-breaking rod 31 are arranged at an angle, and the self-priming push rod 30 is used to push the transmission assembly 2 to switch from the semi-locked state to the fully locked state, and the ice-breaking rod 31 is used to push the transmission assembly When the cam 2 is in the fully locked state, the cam 2 is in the semi-locked state, and the cam 2 is in the fully locked state, the cam 2 is in the semi-locked state, and the cam 2 is in the fully locked state, the cam 2 is in the semi-locked state, and the cam 2 is in the semi-locked ... Figure 2 When the release assembly 4 is in the second position, the release assembly 4 is disengaged from the ice-breaking rod 31, and the drive assembly 3 is rotated in a direction close to the transmission assembly 2, so that the transmission assembly 2 is switched from the fully locked state to the semi-locked state.

[0054] Specifically, this solution realizes the self-priming and ice-breaking functions respectively by arranging the self-priming push rod 30 and the ice-breaking rod 31 on the same side on the driving component 3. When the driving component 3 drives the self-priming push rod 30 and the ice-breaking rod 31 to move along the same side direction, Figures 1 to 2 As shown, before the release assembly 4 makes any movement, one end of the release assembly 4 rests on the ice-breaking rod 31, so that the ice-breaking rod 31 is located in the direction of the transmission assembly 2, that is, Figure 2 The staggered arrangement shown, therefore Figure 2 In the state, if the driving component 3 drives the ice-breaking rod 31 and the self-priming push rod 30 to approach the transmission component 2 in the direction of the driving component 2, the ice-breaking rod 31 will not give the transmission component 2 a force to rotate because it is staggered with the transmission component 2, while the self-priming push rod 30 applies a driving force to the transmission component 2 during the movement, so that the transmission component 2 rotates and realizes the transition from a semi-locked state to a fully locked state during the rotation process (such as Figure 3 The position of the transmission assembly 2 shown in FIG); and after the release assembly 4 moves, it is in the position shown in FIG. Figure 4 The position shown in FIG. 4 is such that the release assembly 4 no longer abuts against the ice-breaking rod 31. Figure 5The ice-breaking rod 31 shown is on the rotation trajectory of the transmission component 2. When the driving component 3 drives the ice-breaking rod 31 and the self-priming push rod 30 to approach along the direction of the transmission component 2 again, the ice-breaking rod 31 can push the transmission component 2 from the fully locked state to the semi-locked state. At the same time, because one end of the release component 4 is rotating and disengaging from the ice-breaking rod 31, it also synchronously pushes the self-priming push rod 30 away from the transmission component 2, so as to avoid the driving component 3 driving the self-priming push rod 30 to move against the transmission component 2 and affect the normal ice-breaking operation of the ice-breaking rod 31.

[0055] In the above process of realizing the self-priming and ice-breaking functions, we can see that the driving component 3 moves in the same direction for the door lock structure whether it is self-priming or ice-breaking (i.e. Figure 2 The driving assembly 3 shown in the figure rotates in a clockwise direction), so the driving assembly 3 realizes that the external actuator (not shown in the figure) can complete the self-priming and ice-breaking functions by sending the same signal through the change of the door lock structure, avoiding the phenomenon that the command errors are easy to occur during the self-priming and ice-breaking processes controlled by multiple signals respectively, thereby ensuring that the customer's user experience is not affected.

[0056] The mounting plate 1 includes a base plate 10 and a cover plate 11 connected to each other. A lock tongue 20 and a pawl 21 are movably provided on the transmission assembly 2 and are located between the base plate 10 and the cover plate 11. When the lock tongue 20 rotates, it is used to push the pawl 21 to rotate, and the pawl 21 limits the lock tongue 20 to a semi-locked state and a fully locked state.

[0057] like Figures 2 to 3 As shown, the lock tongue 20 and the pawl 21 are both rotatably arranged on the bottom plate 10. Specifically, as shown in FIG. Figure 2 As shown, at this time, the ice breaking rod 31 is abutted by the release assembly 4 so that it is located above the lock tongue 20, that is, in a staggered arrangement state. When the driving assembly 3 moves along the Figure 2 When the self-priming push rod 30 rotates clockwise as shown, the self-priming push rod 30 is hinged to the ice-breaking rod 31 on the driving assembly 3, so the self-priming push rod 30 is rotated clockwise. Figure 2 The status shown moves to Figure 3 In the state shown, the self-priming push rod 30 also abuts against the lock tongue 20 during the movement, and then the lock tongue 20 is driven to rotate by the movement of the self-priming push rod 30, and finally the lock tongue 20 is converted from a semi-locked state to a fully locked state, realizing the self-priming function of the door lock.

[0058] Further, in Figure 2 The positions of the self-priming push rod 30 and the ice-breaking rod 31 are when the door is in a fully open state, and the positions of the lock tongue 20 and the pawl 21 in a semi-locked state are when the ice-breaking rod 31 is in a semi-locked state. Figure 2 The fully open state is Figure 3The middle position of the fully locked state is shown, and the self-priming push rod 30 is in a state where it abuts against the lock tongue 20 but does not apply a thrust thereto. The specific state diagram is not shown in the accompanying drawings. Therefore, when the door lock is in the process of changing from a semi-locked state to a fully locked state, that is, the car door is in the process of changing from half-open to closed, the self-priming function of the door lock is realized by the self-priming push rod 30.

[0059] A first locking surface 200 and a second locking surface 201 are provided on the lock tongue 20, and a locking arc surface 210 is provided on the pawl 21; when the lock tongue 20 is in a semi-locked state, the locking arc surface 210 abuts against the first locking surface 200; when the lock tongue 20 rotates from the semi-locked state to the fully locked state, the lock tongue 20 is used to push the pawl 21 to rotate relative to the base plate 10, so that the locking arc surface 210 abuts against the second locking surface 201 and limits the lock tongue 20 to the fully locked state.

[0060] Specifically, in the process of the self-priming push rod 30 abutting against and pushing the lock tongue 20 to rotate from the semi-locked state to the fully locked state, the pawl 21 is required to ensure the stability of the lock tongue 20 in the semi-locked state or the fully locked state. Figure 2 As shown, the locking arc surface 210 on the pawl 21 abuts against the first locking surface 200 of the lock tongue 20, thereby limiting the lock tongue 20 from rotating in the clockwise direction. Figure 2 When the lock tongue 20 rotates counterclockwise, the lock tongue 20 can push the pawl 21 to rotate in a direction away from the lock tongue 20 during the process of rotating from the semi-locked state to the fully locked state. Figure 2 As shown in the clockwise direction, when the second locking surface 201 is located above the locking arc surface 210, the pawl 21 can be rotated in the direction close to the lock tongue 20 to reset, and finally as shown in the Figure 3 The locking arc surface 210 on the pawl 21 abuts against the second locking surface 201 on the lock tongue 20, limiting the lock tongue 20 to a fully locked state.

[0061] Further, with respect to the reset of the pawl 21, as shown in FIG. Figure 2 The bottom plate 10 is provided with a torsion spring, one end of which is connected to the pawl 21, so that when the lock tongue 20 moves along the Figure 2 When the pawl 21 is rotated counterclockwise and pushed away in the clockwise direction, the torsion spring is in a contracted and tensioned state. When the second locking surface 201 on the lock tongue 20 rotates to be located above the clamping claw, the lock tongue 20 no longer applies a rotational force to the pawl 21, and the pawl 21 can be reset by relying on the torsion spring and rest against the lock tongue 20 again, completing the position limitation of the lock tongue 20 and ensuring the stability of the door lock structure when it is in a semi-locked state or a fully locked state.

[0062] The driving assembly 3 includes: a self-priming pull wire 32 for connecting the actuator; a self-priming connecting rod 33 rotatably arranged on the cover plate 11, the self-priming pull wire 32 is connected to the self-priming connecting rod 33, the self-priming push rod 30 and the ice-breaking rod 31 are located on the same side of the self-priming connecting rod 33, and the self-priming push rod 30 and the ice-breaking rod 31 both extend between the base plate 10 and the cover plate 11.

[0063] Similarly, for the movement of the driving component 3, the self-priming push rod 30 and the ice-breaking rod 31 are arranged on the same side of the self-priming connecting rod 33 and extend between the bottom plate 10 and the cover plate 11, which is conducive to pulling the self-priming pull line 32 through the external actuator, and the same signal can be used to make the self-priming push rod 30 and the ice-breaking rod 31 move in the same direction to realize the self-priming and ice-breaking functions respectively. Furthermore, in order to ensure that the self-priming connecting rod 33, the self-priming push rod 30 and the ice-breaking rod 31 in the driving component 3 can all be automatically reset after completing the specified action, so as to ensure the normal operation of the subsequent self-priming and ice-breaking functions of the door lock structure, Figure 1 As shown, torsion springs with the same functions as above are provided on the self-priming connecting rod 33, the self-priming push rod 30 and the ice-breaking rod 31. The torsion springs are used to achieve reset after the completion of their respective work, ensuring the smoothness and stability of the door lock structure function during the implementation process.

[0064] A first self-priming arc surface 300 is provided on the self-priming push rod 30 , and a second self-priming arc surface 202 is provided on the lock tongue 20 . The first self-priming arc surface 300 movably abuts against the second self-priming arc surface 202 .

[0065] like Figure 3 As shown, in the process of the self-priming push rod 30 giving the lock tongue 20 a rotational force, the first self-priming arc surface 300 on the self-priming push rod 30 will abut against the second self-priming arc surface 202 on the lock tongue 20 during the movement. Through the mutual abutment of the two self-priming arc surfaces, the lock tongue 20 is finally rotated from a semi-locked state to a fully locked state. It should be noted that it is precisely because the self-priming push rod 30 is in the Figure 2 Status moved to Figure 3 When in the state, the lock tongue 20 is switched to another state. In order to ensure that when the ice-breaking rod 31 breaks the ice on the lock tongue 20, the synchronously moving self-priming push rod 30 no longer applies thrust to the lock tongue 20. This is also the main reason for moving the self-priming push rod 30 in the direction away from the lock tongue 20 by the release component 4 mentioned above, ensuring that the ice-breaking rod 31 is not affected by the movement of the self-priming push rod 30 during the process of breaking the ice on the lock tongue 20.

[0066] The release assembly 4 includes: a snow-load link 40, which is rotatably arranged between the base plate 10 and the cover plate 11, and is used to limit the rotation of the pawl 21 along the direction of the lock tongue 20; an unlocking link 41 located on the side of the base plate 10 away from the cover plate 11, and the unlocking link 41 is connected to the pawl 21 and is coaxially arranged therewith; an interrupting rod 42, which is rotatably arranged on the base plate 10 and coaxially arranged with the lock tongue 20, and the interrupting rod 42 is movably abutted against the ice-breaking rod 31 and is used to push the self-priming push rod 30 away from the lock tongue 20; a connecting rod portion rotatably arranged on the base plate 10, and the rotation axis of the connecting rod portion is coaxially arranged with the rotation axis of the snow-load link 40, and one end of the connecting rod portion abuts against the unlocking link 41, and the other end of the connecting portion 43 is connected to the interrupting rod 42.

[0067] Specifically, the main function of the release assembly 4 is to make the ice breaking rod 31 in the ice breaking position, so as to ensure that the ice breaking function of the lock tongue 20 is achieved during the movement of the ice breaking rod 31. Figure 1 The figure shows the state of the release assembly 4 in the first position. Usually, after the door lock structure receives the door opening signal, the pawl 21 can be released. Figure 3 The position shown is rotated clockwise away from the locking tongue 20, and the pawl 21 pushes the snow load link 40 above it along the rotation process. Figure 3 Rotate counterclockwise, when the pawl 21 is in Figure 4 When the snow load link 40 is in the position shown, since the snow load link 40 is also provided with a torsion spring, the snow load link 40 can be reset to the position after the rotation by relying on the torsion spring. Figure 3 The position shown in the figure further restricts the movement of the clamping claw along the direction of the lock tongue 20, ensuring that the ice breaking rod can normally break the ice. At this time, if the car door is frozen, the lock tongue 20 cannot return to its original position naturally, and the electric release and ice breaking process can be started at this time:

[0068] Since the unlocking link 41 is connected to the pawl 21 and is coaxially arranged therewith, when the pawl 21 rotates to Figure 4 When the unlocking link 41 is in the position, the unlocking link 41 rotates synchronously with the pawl 21, that is, the unlocking link 41 rotates along the Figure 1 When the unlocking link 41 rotates, it pushes the connecting portion 43 to rotate, and finally drives the interrupting rod 42 to rotate along the unlocking link 41. Figure 1 Turn clockwise until Figure 5 In the position shown (i.e. the second position of the release assembly 4), during the rotation process, the interruption lever 42 is moved from Figure 1 The state of supporting the ice breaking rod 31 is shown to Figure 5 As shown in the state of being separated from the ice-breaking rod 31, the end of the self-priming push rod 30 close to the first self-priming arc surface 300 is pushed away from the lock tongue 20 to avoid the self-priming push rod 30 and the lock tongue 20 from contacting during the ice-breaking action, thereby affecting the normal realization of the ice-breaking function. At this time, the ice-breaking rod 31 is in Figure 4The position shown in FIG. 3 is that the ice breaking rod 31 is located on the rotation path of the lock tongue 20, and then the actuator drives the self-priming pull line 32 as shown in FIG. Figure 6 When moving to the left as shown, the ice-breaking rod 31 pushes the locking tongue 20 to rotate during the process of moving to the right, thereby achieving the purpose of breaking ice.

[0069] Further, along the icebreaker rod Figure 6 When moving to the right to perform the ice-breaking function, the ice-breaking rod rests against the lock tongue, causing the lock tongue to switch from a fully locked state to a semi-locked state. Preferably, during the process of the ice-breaking rod breaking ice, when the lock tongue rotates to the semi-locked state, the ice-breaking rod can continue to push the lock tongue to a position between the semi-locked state and the fully open state, that is, the car door is in a position close to the fully open position at this time, which is conducive to ensuring that the car door is accurately in the open state after the ice-breaking rod completes the ice-breaking function.

[0070] The connecting rod portion includes: an inner and outer conversion rod 430, which is rotatably arranged on the base plate 10 and coaxially arranged with the rotating axis of the snow load connecting rod 40, and a protrusion block 4300 is provided on the inner and outer conversion rod 430, and the protrusion block 4300 abuts on the unlocking connecting rod 41; an interrupt connecting rod 431, one end of the interrupt connecting rod 431 is hinged to the end of the inner and outer conversion rod 430 away from the protrusion block 4300, and the other end of the interrupt connecting rod 431 is connected to the interrupt rod 42.

[0071] Furthermore, for the connecting rod portion mentioned above, in this solution, by setting the inner and outer conversion rods 430 and the interruption connecting rod 431, the rotation force of the unlocking connecting rod 41 is finally transmitted to the interruption rod 42, so as to achieve the effect of electric release. Specifically, when the unlocking connecting rod 41 is rotated along the direction shown in FIG. Figure 1 When rotating counterclockwise, since the protruding block 4300 is located on the left side of the unlocking link 41, the unlocking link 41 can abut against the protruding block 4300 when rotating, thereby pushing the inner and outer conversion rod 430 along the inner and outer conversion rod 430. Figure 1 The interruption connecting rod 431 is connected to the inner and outer conversion rod 430 at one end and to the interruption rod 42 at the other end. Therefore, when the inner and outer conversion rod 430 rotates, the interruption connecting rod 431 can be used to push the interruption rod 42 from the inner and outer conversion rod 430 to the inner and outer conversion rod 430. Figure 1 Turn clockwise to the position shown Figure 5 The position shown in FIG. 2 is used to make the ice-breaking rod 31 be in a position where the locking tongue 20 can be broken into ice.

[0072] Preferably, in addition to the above-mentioned design method of setting the internal and external conversion rods 430 and the interrupt connection rod 431 to ultimately realize the rotation of the interrupt rod 42 to the desired position, but this design method is not one of the embodiments in this scheme, the transmission of gears meshing with each other can also be used to achieve the ultimate purpose of this scheme.

[0073] An ice-breaking rod rivet 310 is provided at one end of the ice-breaking rod 31 away from the self-priming connecting rod 33 , and a guide groove 100 is provided on the base. The ice-breaking rod rivet 310 passes through the guide groove 100 and is located above the self-priming push rod 30 .

[0074] In order to ensure the stability of the ice-breaking rod 31 during the ice-breaking operation, the ice-breaking rod rivet 310 on the ice-breaking rod 31 plays a role in adjusting the position of the ice-breaking rod 31. Figure 1 When the door is fully opened, the interruption rod 42 is supported on the ice breaking rod rivet 310, so that the ice breaking rod 31 is located as shown in FIG. Figure 2 As shown above the locking tongue 20, the purpose of staggered arrangement is achieved, and when the interruption rod 42 is as shown Figure 5 As shown in FIG, when the ice-breaking rod rivet 310 is separated, the ice-breaking rod rivet 310 is located on the guide groove 100. When the actuator gives the self-priming wire 32 a Figure 6 When the signal of left movement is shown, the ice-breaking rod 31 and the ice-breaking rod rivet 310 move to the right along the bottom contour of the guide groove 100, and finally the ice-breaking rod 31 abuts against the lock tongue 20 and pushes the lock tongue 20 along the bottom contour of the guide groove 100. Figure 6 Turn clockwise from full lock to half lock to complete the ice breaking function.

[0075] Furthermore, the guide groove 100 plays a guiding role when the ice-breaking rod 31 breaks ice. Figure 1 When the position is shown, the top of the interruption rod 42 and the top of the guide groove 100 form a space for the ice breaking rod rivet 310 to move, and then the self-priming push rod 30 is as shown. Figure 2 When moving toward the lock tongue 20 and resting against the lock tongue 20 to perform the self-priming function, the ice-breaking rod 31 can also rely on the ice-breaking rod rivet 310 to move between the interrupting rod 42 and the top of the guide groove 100, ensuring that the ice-breaking rod 31 is still above the lock tongue 20 during the movement, thereby avoiding the ice-breaking rod 31 affecting the normal self-priming push rod 30 to realize the self-priming function during the movement.

[0076] The interrupt rod 42 also includes: a support surface 420 and a disengagement surface 421, the support surface 420 is connected to the disengagement surface 421, and the support surface 420 and the disengagement surface 421 are set at an angle, the support surface 420 is used to abut against the ice-breaking rod rivet 310, and the disengagement surface 421 is used to disengage from the ice-breaking rod rivet 310, so that the ice-breaking rod rivet 310 is located on the guide groove 100; a driving surface 422, which is provided on the side of the interrupt rod 42 close to the self-priming push rod 30, and the self-priming push rod 30 is provided with a self-priming push rod rivet 301 close to the first self-priming arc surface 300, and the driving surface 422 is used to movably abut against the self-priming push rod rivet 301, so that the self-priming push rod 30 is away from the lock tongue 20.

[0077] Regarding how to realize the interruption rod 42 supporting or separating from the ice breaking rod rivet 310, specifically, as Figure 1 The interruption rod 42 is in the position shown in FIG. 4 , at which time the support surface 420 on the interruption rod 42 supports the ice-breaking rod rivet 310, so that the ice-breaking rod 31 is above the lock tongue 20. When the interruption rod 42 is rotated to Figure 5 When the locking bolt 20 is in the unlocked position, the locking bolt 20 is unlocked and the locking bolt 20 is unlocked. Figure 2 As shown in the initial position, when the ice-breaking rod 31 realizes the ice-breaking function, the self-priming push rod 30 moves in a path that is staggered with the lock tongue 20 when switching from the fully locked state to the semi-locked state, thereby ensuring the smoothness of the ice-breaking rod 31 in breaking the ice on the door lock.

[0078] A door lock structure with self-priming and ice-breaking functions according to the present invention also includes: an outward-opening link 5 rotatably set on the base plate 10, which is coaxially arranged with the snow-load link 40, and the outward-opening link 5 abuts against the inner-outer conversion rod 430; a coupling rod 6, which is rotatably set on the inner-outer conversion rod 430, and a fixed column 410 is provided on the unlocking link 41, and the coupling rod 6 movably abuts against the fixed column 410; an induction switch 7, which is set on the base plate 10, and a circular arc surface 411 is provided on the unlocking link 41, and the circular arc surface 411 movably abuts against the induction switch 7, and the rotation position of the pawl 21 is detected by the induction switch 7.

[0079] The movement of the release assembly 4 mainly realizes the structural principle of the door lock opening inward. When the user pulls the door handle from outside the door, the outward opening connecting rod 5 on the bottom plate 10 moves along the Figure 1 When the outer opening link 5 rotates clockwise, the inner and outer conversion rods 430 will be pushed to move synchronously in the clockwise direction. Since the coupling rod 6 is arranged on the inner and outer conversion rods 430, when the inner and outer rotation rods rotate, the coupling rod 6 is driven to rotate synchronously and abut against the fixing column 410 of the unlocking link 41, thereby causing the unlocking link 41 to move in the clockwise direction. Figure 1As shown in the counterclockwise direction, the arc surface 411 of the unlocking link 41 finally abuts against the induction switch 7. As mentioned above, the unlocking link 41 is connected to the pawl 21, and the rotation of the unlocking link 41 drives the pawl 21 to rotate synchronously, that is, the pawl 21 is in Figure 4 The position shown in FIG. 2 shows that the locking tongue 20 can also be rotated when it is not frozen. Figure 1 The position of the coupling rod 6 is such that the user can unlock the door by pulling the door handle. In addition, a movable locking block (not shown) is provided at the base, and when the end of the locking block is in the Figure 1 When the fixing rod is in the right position as shown, the user pulls the door handle, and the outer opening link 5 moves along the Figure 1 The coupling rod 6 rotates clockwise, and the coupling rod 6 abuts against the locking block around the connection between it and the inner and outer conversion rod 430, and moves downward along the locking block in the vertical direction. At this time, the coupling rod 6 and the fixed column 410 are staggered, that is, the coupling rod 6 no longer gives the unlocking link 41 a force to rotate, so the pawl 21 connected to the unlocking link 41 is still in the same position. Figure 2 The locking state of the lock tongue 20 is shown, thereby ensuring that the vehicle door is in a locked state.

[0080] Furthermore, the movement of the locking block can be driven by a motor, and the movement of the locking block is along Figure 1 The coupling rod 6 moves in the horizontal direction and is restrained by the locking block to abut against the fixing column 410 of the unlocking link 41, thereby ensuring that the door is in a locked state when the user pulls the door outer handle.

They will not be described one by one here. In this article, the position of the lock tongue 20 can be detected by a position sensor and an induction signal.
