Emergency door lock structure, stand structure assembly and vehicle

Abstract

This application provides an emergency door lock structure, a pillar structure assembly, and a vehicle, belonging to the field of automotive door lock technology. By placing the outward-opening handle and the door lock body within the internal space of the same vehicle pillar, the problems of large absolute elongation of the outward-opening cable, easy wear due to numerous bends, and easy jamming due to dynamic clearance are effectively improved, resulting in increased force transmission efficiency and a significantly reduced failure rate. By positioning the outward-opening handle above the door lock body, its height is increased, allowing rescue personnel outside the vehicle to operate the handle more conveniently without having to bend over at a large angle, thus improving ease of use. By setting the outward-opening pull member as an outward-opening cable and wrapping the outer periphery of the cable with a protective sleeve, the outward-opening pull member can bend flexibly, greatly increasing the degree of freedom in layout within a relatively confined space. Furthermore, the protective sleeve restricts the movement of the outward-opening cable, making its movement more stable.

Description

Technical Field

[0001] This application belongs to the field of automotive door lock technology, and more specifically, relates to an emergency door lock structure, a pillar structure assembly, and a vehicle. Background Technology

[0002] With the development of automotive intelligence, most car door lock systems are controlled by the Body Control Module (BCM) via electrical signals, forming a central locking system. When a vehicle is involved in a serious accident (such as a collision causing a power outage), the battery is completely dead, or the door lock motor or sensors malfunction, the electronic unlocking function will fail. In this situation, the external unlock cable provides a mechanical connection that does not rely on any electricity, ensuring the door can be manually unlocked and opened from the outside, which is crucial for post-accident rescue.

[0003] While meeting basic safety functions, the placement of car door locks varies depending on factors such as vehicle model positioning, ergonomics, and ease of operation. Some models install door locks on the side of the vehicle body (B-pillar, C-pillar, etc.), requiring the exterior door handle to connect to the side door lock via an outward-opening cable. However, the outward-opening cable cannot extend directly to the side door lock, often requiring it to travel a considerable distance around the door and body. During door opening and closing, the outward-opening cable experiences high wear and low force transmission efficiency, making it prone to jamming and other problems. This leads to malfunctions during the outward-opening unlocking process, affecting the reliability of emergency door opening. Utility Model Content

[0004] The purpose of this application is to provide an emergency door lock structure, a pillar structure assembly, and a vehicle, which aims to solve the problem that the existing outward-opening pull cable layout is unreasonable and prone to failure during use.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide an emergency door lock structure, including: The door lock body is located in the inner cavity of the vehicle body pillar and corresponds to the locking position of the door; An outward-opening handle is located on the outside of the vehicle body pillar; The outward-opening handle is connected to the door lock body via an outward-opening pull member, so that people outside the vehicle can release the locking state of the door lock body through the outward-opening handle.

[0006] In existing designs where door locks are integrated into the vehicle body, one end of the door handle is connected to the outward-opening cable. This cable extends along the space below the door glass to the hinge side of the door, then passes through the door and into the corresponding pillar. For example, if the door lock is located on the B-pillar, the cable extends longitudinally within the cavities of the inner and outer door panels, and then extends from the hinge side into the body space below the A-pillar. Subsequently, the cable extends downwards to the sill beam, and then rearwards within the sill beam to the B-pillar. Within the B-pillar's cavity, the cable extends upwards until it connects with the door lock inside the B-pillar. Therefore, the outward-opening cable needs to travel a considerable distance within the door and body; in some models, the cable length can even reach 4 to 5 meters.

[0007] The negative impact of this arrangement on the unlocking process is as follows: First, the longer the outward-opening cable, the greater its overall absolute elongation, the higher the lag in the unlocking action, and the lower the force transmission efficiency.

[0008] Secondly, the longer the external opening guy wire is, the more bends there are in the layout path. The external opening guy wire is prone to wear in the bends. In severe cases, the external opening guy wire breaks, which directly causes the external opening unlocking function to fail.

[0009] Third, the outward-opening cable needs to pass through the door and into the body, and the dynamic gap between the door and the body can easily cause the outward-opening cable to get stuck.

[0010] The factors mentioned above all negatively impact the smoothness and reliability of the door opening and unlocking process, resulting in a high failure rate.

[0011] Compared with the prior art, the solution shown in this application embodiment has both the outward opening handle and the door lock body installed on the vehicle body pillar. When in use, rescue personnel outside the vehicle can directly pull the outward opening handle from outside the vehicle, which will drive the door lock body to unlock through the outward opening pull component, thus completing the outward opening and unlocking function.

[0012] This application places the outward-opening handle and door lock body within the same interior space of the vehicle pillar. The outward-opening pull member does not need to travel a long distance within the door and body; it can extend directly within the interior cavity of the pillar along the layout path of the handle and lock body, significantly shortening its length and effectively reducing the number of bends. It can even be designed to extend in a straight line. Furthermore, this application avoids designs that penetrate the vehicle body through the door, and the dynamic gap between the door and body will not affect the outward-opening pull member.

[0013] Compared with the traditional outward-opening guy wire arrangement, this application effectively improves the problems of large absolute elongation of outward-opening guy wires, easy wear due to numerous bends, and easy jamming due to dynamic gaps, thereby improving force transmission efficiency and effectively reducing the failure rate.

[0014] In conjunction with the first aspect, in one possible implementation, the outward-opening handle is located above the door lock body.

[0015] In the above technical solution, while ensuring that the door lock body and the door lock position correspond, the height of the outward opening handle is raised, so that rescuers outside the vehicle can operate the outward opening handle more conveniently without having to bend over at a large angle, thereby improving the ease of use and thus improving rescue efficiency.

[0016] In conjunction with the first aspect, in one possible implementation, the outward-opening pulling member is an outward-opening pull wire, and the outer periphery of the outward-opening pull wire is wrapped with a protective sleeve.

[0017] In the aforementioned technical solution, the outward-opening pull member can bend flexibly, avoiding obstacles between the pull cable connection points on the outward-opening handle and the door lock body, finding the optimal extension path, and greatly increasing the degree of layout freedom in relatively confined spaces. Furthermore, when the outward-opening handle opens and closes the door, the outward-opening pull cable slides within the protective sleeve, preventing friction and damage to external metal parts. In addition, the protective sleeve also restricts the movement of the outward-opening pull cable, making its movement more stable.

[0018] In conjunction with the first aspect, in one possible implementation, the outward-opening handle includes: A handle base is fixed to the outer plate of the vehicle body pillar, and a base opening is formed through the handle base; The handle body has a drive swing arm on its inner side. The drive swing arm passes through the base opening from the outside to the inside and is rotatably connected to the handle base. A traction drive component is rotatably connected to the inner side of the handle base, and its rotation axis is perpendicular to the rotation axis of the drive swing arm. One end of the outward-opening traction component is connected to the traction drive component. The drive end of the drive arm can drive the pull drive component to rotate, so that the outward-opening pull component pulls the bolt of the door lock body.

[0019] In the above technical solution, the overall structure of the outward-opening handle is simple and compact. Through the cooperation between the outward-opening handle and the pull drive component, the drive process is simple, which can fully meet the drive requirements of the door lock body and has good reliability.

[0020] In some embodiments, a connecting arm is provided on the inner side of the handle base, the connecting arm is provided corresponding to the opening of the base, and is rotatably connected to the drive swing arm; The drive arm includes a first drive section and a second drive section connected to each other. The first drive section and the second drive section are set at an angle. The first drive section is also connected to the handle body. The second drive section can contact the traction drive component.

[0021] In the above technical solution, the first rotating shaft is moved rearward by connecting the arm to meet the assembly requirements with the drive swing arm. This also achieves a compact design for the handlebar base in both the inner and outer directions, preventing excessive thickness of the handlebar base from interfering with other components inside the vehicle body pillar. It also reduces the material usage of the handlebar base, achieving a lightweight and low-cost design. Furthermore, the segmented design of the drive swing arm makes its structural design more flexible and adaptable.

[0022] In some embodiments, an elastic reset member is provided between the pull drive member and the handle base, and the elastic reset member is configured with a preload to bring the drive end of the pull drive member closer to the door lock body.

[0023] The above technical solution achieves automatic reset of the outward-opening handle, making it more convenient to use. At the same time, it simplifies the adaptation structure between the drive arm and the traction drive component, allowing them to push each other stably, resulting in a simpler structure.

[0024] In some embodiments, the traction drive has a driven arm and a plurality of traction arms, the driven arm and the plurality of traction arms being spaced apart around the axis of rotation of the traction drive; The driving end of the driving arm contacts the driven arm, and the driven arm drives the traction drive component to rotate. The outward-opening traction member is connected to one of the traction arms.

[0025] In the above technical solution, an extended arm-like structure is used to accommodate the drive swing arm and the outward-opening traction component, reducing the material usage of the traction drive component and achieving a lightweight design. Furthermore, because multiple traction arms are provided, the traction drive component can be flexibly selected to connect to any traction arm based on installation requirements such as vehicle model, resulting in greater flexibility in traction drive component adaptation.

[0026] Secondly, this application embodiment also provides a pillar structure assembly, including a vehicle body pillar and the aforementioned emergency door lock structure, wherein the door lock body of the emergency door lock structure is disposed in the inner cavity of the vehicle body pillar, and the outward opening handle of the emergency door lock structure is disposed on the outer side of the vehicle body pillar.

[0027] Compared with the prior art, the solution shown in this application, by adopting the above-mentioned emergency door lock structure, effectively improves the smoothness of opening and unlocking from the outside, reduces the failure rate of the opening and unlocking process, and improves the safety and reliability of use.

[0028] In conjunction with the second aspect, in one possible implementation, the outer panel of the vehicle body pillar includes a lower extension of the outer panel of the roof and an upper extension of the outer panel of the sill beam, wherein the lower edge of the lower extension of the outer panel of the roof connects with the upper edge of the upper extension of the outer panel of the sill beam. The outward-opening handle is connected to the extension section of the outer plate of the sill beam; The main body of the door lock is located on the inner side of the extended section of the outer plate of the threshold beam, and is set to correspond to the connection gap between the lower extended section of the outer plate of the top cover and the upper extended section of the outer plate of the threshold beam.

[0029] In the above technical solution, the lower extension section of the roof outer panel is used to form the pillar outer panel, which improves the continuity between the pillar outer panel and the roof outer panel, thereby improving the aesthetics of the side structure design of the vehicle body, while also fully meeting the assembly requirements of the outward-opening handle.

[0030] Thirdly, embodiments of this application also provide a vehicle including the aforementioned pillar structure assembly.

[0031] Compared with the prior art, the solution shown in this application improves the smoothness of emergency unlocking by adopting the above-mentioned column structure assembly, and reduces the failure rate, which is conducive to improving the reliability and safety of the vehicle and also enhances the overall quality of the vehicle.

[0035] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0036] It should be noted that when a component is referred to as being "set on" another component, it can be directly on the other component or indirectly on that other component.

[0037] It should be noted that the terms "upper" and "lower" refer to the vertical direction of the vehicle body, "left" and "right" refer to the horizontal direction of the vehicle body, "front" and "rear" refer to the front and rear direction of the vehicle body, "inner" refers to the direction towards the passenger compartment, and "outer" refers to the direction away from the passenger compartment. Other directional terms, unless otherwise explicitly specified, where the use of terms such as "length," "width," "top," and "bottom" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] In existing designs where door locks are integrated into the vehicle body, one end of the door handle is connected to the outward-opening cable. This cable extends along the space below the door glass to the hinge side of the door, then passes through the door and into the corresponding pillar. For example, if the door lock is located on the B-pillar, the cable extends longitudinally within the cavities of the inner and outer door panels, and then extends from the hinge side into the body space below the A-pillar. Subsequently, the cable extends downwards to the sill beam, and then rearwards within the sill beam to the B-pillar. Within the B-pillar's cavity, the cable extends upwards until it connects with the door lock inside the B-pillar. Therefore, the outward-opening cable needs to travel a considerable distance within the door and body; in some models, the cable length can even reach 4 to 5 meters.

[0040] First, the outward-opening door cable undergoes a certain degree of elastic deformation under stress. When the outer door handle is pulled, the force is first used to stretch the cable, rather than immediately acting on the door lock. This results in a slight lag in the unlocking action, and this lag represents energy loss. The longer the outward-opening door cable, the greater its overall absolute elongation under the same pulling force (according to Hooke's Law, deformation is proportional to length), and the stronger the lag. Therefore, an excessively long outward-opening door cable directly affects the force transmission efficiency.

[0041] Secondly, due to the very compact space inside the car doors and body, and the fact that the outward-opening cable arrangement cannot obstruct the open space of the car body after the door is opened, the outward-opening cable cannot be laid out in a straight line; it usually has multiple bends and corners. Each time the outward-opening cable bends, the contact pressure and friction between the wire core and the sheath increase sharply, and the wear at the bend location also increases accordingly. This not only increases frictional resistance but also easily leads to wear and even breakage of the wire core, causing the outward-opening function to fail. Therefore, the more bends the outward-opening cable has, the higher the risk of wear and breakage.

[0042] Secondly, the dynamic clearance between the door and the body mainly refers to the actual fit clearance between the door and the body during movement (such as when opening and closing, when the body undergoes torsional deformation during driving, or when the door sags). When the clearance becomes smaller, it will squeeze or bend the outward opening cable; when the clearance becomes larger, it will overstretch the outward opening cable. If these changes exceed the design tolerance, the outward opening cable will be obstructed within the protective sleeve, resulting in jamming, making the outward opening handle heavy to operate or even completely stuck.

[0043] It is evident that the long-distance arrangement of the outward-opening cable has a negative impact on the smoothness and reliability of the outward-opening unlocking operation, resulting in a higher failure rate of the outward-opening door structure, which in turn affects the overall safety of the vehicle.

[0044] To resolve the above issues, please refer to the following: Figures 1 to 10 The emergency door lock structure provided in this application is described below. The emergency door lock structure includes a door lock body 100 and an outward-opening handle 200. The door lock body 100 is located within the inner cavity of the vehicle body pillar 400 and corresponds to the locked position of the vehicle door. The outward-opening handle 200 is located on the outer side of the vehicle body pillar 400. The outward-opening handle 200 is connected to the door lock body 100 via an outward-opening pull member 300, allowing personnel outside the vehicle to release the locked state of the door lock body 100 via the outward-opening handle 200.

[0045] In this embodiment, the door lock body 100 can be an existing vehicle door lock, and its specific structure will not be described in detail here. The outward opening pull member 300 can be a flexible member or a rigid member, as long as it can meet the requirements for pulling and unlocking the door lock body 100.

[0046] Figure 1 The image shows an example of an emergency door lock structure mounted on the left side of the vehicle. It should be understood that the emergency door lock structures on the left and right sides of the vehicle are symmetrically arranged, and the structure on the other side will not be described in detail here.

[0047] Compared with the prior art, the emergency door lock structure provided in this application sets both the outward opening handle 200 and the door lock body 100 on the vehicle body pillar 400. When in use, rescue personnel outside the vehicle can directly pull the outward opening handle 200 from outside the vehicle, and the door lock body 100 can be driven by the outward opening pull member 300 to unlock, thus completing the outward opening and unlocking function.

[0048] In this embodiment, the outward-opening handle 200 and the door lock body 100 are located within the same interior space of the vehicle pillar 400. The outward-opening pull member 300 does not need to travel a long distance within the door and body; it can extend directly within the interior cavity of the vehicle pillar 400 along the layout path of the outward-opening handle 200 and the door lock body 100. This significantly shortens the length of the outward-opening pull member 300, effectively reducing the number of turning areas, and even allowing for a straight-line extension design. Furthermore, this embodiment avoids the design of penetrating the vehicle body through the door, and the dynamic gap between the door and the body does not affect the outward-opening pull member 300.

[0049] Compared to traditional outward-opening cable arrangements, this embodiment effectively improves upon the problems of large absolute elongation of outward-opening cables, easy wear due to numerous bends, and susceptibility to jamming due to dynamic clearance, thereby improving force transmission efficiency and effectively reducing the failure rate. Furthermore, this embodiment makes full use of the vehicle's interior space, requiring no modifications to the door's internal structure, and significantly reducing the cost of arranging the emergency door lock structure.

[0050] In some embodiments of the spatial layout of the door lock body 100 and the outward-opening handle 200, see... Figures 1 to 4 The outward-opening handle 200 is located above the door lock body 100. In this embodiment, while ensuring that the door lock body 100 corresponds to the door lock position, the height of the outward-opening handle 200 is raised, so that rescuers outside the vehicle can operate the outward-opening handle 200 more conveniently without having to bend over at a large angle, thereby improving ease of use and thus improving rescue efficiency.

[0051] In practice, the outward-opening handle 200 and the door lock body 100 are aligned vertically in the front-rear direction, or they are staggered in the front-rear direction. The specific spatial layout of the two is determined according to the vehicle model and actual assembly requirements, and will not be listed here. Figure 2 and Figure 6 An embodiment is shown in which the door lock body 100 is located in front of the outward-opening handle 200.

[0052] In other embodiments of the spatial layout of the door lock body 100 and the outward-opening handle 200, the door lock body 100 is located above the outward-opening handle 200. This embodiment, while ensuring the door lock body 100 corresponds to the door lock position, lowers the height of the outward-opening handle 200. For adult users, whose arms are typically positioned to the side of their thighs when hanging naturally, a lower outward-opening handle 200 allows users to open the car door directly in a more relaxed posture, improving the smoothness of the user experience. For children, shorter adults, or wheelchair users, a lower outward-opening handle 200 is easier to reach and operate, increasing the vehicle's inclusivity and convenience.

[0053] In some implementations of the outward-opening tension member 300, see [link / reference]. Figure 4 , Figure 6 and Figure 7 The outward-opening pull member 300 is an outward-opening pull cable. This pull member 300 can bend flexibly, avoiding obstacles between the pull cable connection points on the outward-opening handle 200 and the door lock body 100, finding the optimal extension path. This greatly increases the flexibility of layout within a relatively confined space. Furthermore, unavoidable dimensional and assembly tolerances exist in automobile manufacturing. The flexible outward-opening pull cable has a certain length margin and adaptability, which can compensate for minor dimensional deviations generated during manufacturing and assembly, ensuring that the movement of the outward-opening handle 200 is effectively transmitted to the door lock body 100, without jamming or failure due to tolerances. In addition, the flexible outward-opening pull cable itself has damping characteristics, and the joints usually have rubber buffer pads, which can effectively absorb and dampen vibrations, significantly reducing the risk of abnormal noise and improving the vehicle's NVH performance.

[0054] Based on the outward-opening pull cable design, the pull cable is surrounded by a protective sleeve. During the opening process using the outward-opening handle 200°, the pull cable slides within the protective sleeve, preventing friction and damage to external metal parts. Furthermore, the protective sleeve also restricts the movement of the pull cable, making its movement more stable.

[0055] In practice, the protective sleeve can be made of materials such as polytetrafluoroethylene (PTFE) or nylon, as long as it meets the requirements for protection and assembly. The material for the external pull cord can be stainless steel, carbon fiber composite materials, etc.

[0056] In practice, if the outward-opening guy cable needs to bend, a steering pulley should be installed at the bend to provide tension to the outward-opening guy cable and prevent wear on the outward-opening guy cable.

[0057] In other implementations of the outward-opening pull member 300, the outward-opening pull member 300 is a rigid pull rod. The outward-opening handle 200 drives the pull rod to move linearly, thereby unlocking the door lock body 100. Using a pull rod reduces the force transmission loss between the outward-opening pull member 300 and the door lock body 100, resulting in higher unlocking control efficiency.

[0058] In some embodiments, see Figures 1 to 4 , Figures 6 to 10 The outward-opening handle 200 includes a handle base 210, a handle body 220, and a pull drive member 230. The handle base 210 is fixed to the outer plate of the body pillar 400, and a base opening 211 is formed through the handle base 210. A drive swing arm 240 is provided on the inner side of the handle body 220. The drive swing arm 240 passes through the base opening 211 from the outside to the inside and is rotatably connected to the handle base 210. The pull drive member 230 is rotatably connected to the inner side of the handle base 210, and the axis of rotation is perpendicular to the axis of rotation of the drive swing arm 240. One end of the outward-opening pull member 300 is connected to the pull drive member 230. The drive end of the drive swing arm 240 can drive the pull drive member 230 to rotate, so that the outward-opening pull member 300 pulls the latch of the door lock body 100. Specifically, the pivot between the drive arm 240 and the handle base 210 is designated as the first pivot 270, and the pivot between the traction drive component 230 and the handle base 210 is designated as the second pivot 280. In practice, the first pivot 270 extends vertically, and the second pivot 280 extends horizontally.

[0059] If outward unlocking is required, the handle body 220 is moved. The handle body 220 drives the drive arm 240 to rotate around the first pivot 270. The drive arm 240 pushes the pull drive component 230 to rotate around the second pivot 280. During rotation, the pull drive component 230 pulls the outward opening pull component 300, thereby pulling the bolt of the door lock body 100 to unlock. After unlocking, the handle body 220, drive arm 240, and pull drive component 230 gradually return to their initial state. The outward opening pull component 300 releases its pulling force on the bolt, and the bolt resets. The outward opening handle 200 of this embodiment has a simple and compact overall structure. Through the cooperation between the outward opening handle 200 and the pull drive component 230, the driving process is simple, which can fully meet the driving requirements of the door lock body 100 and has good reliability.

[0060] In some embodiments, see Figures 6 to 9A connecting arm 250 is provided on the inner side of the handle base 210. The connecting arm 250 is set corresponding to the base opening 211 and is rotatably connected to the drive swing arm 240. The drive swing arm 240 includes a first drive section 241 and a second drive section 242 connected to each other. The first drive section 241 and the second drive section 242 are set at an angle. The first drive section 241 is also connected to the handle body 220, and the second drive section 242 can contact the traction drive component 230. In this embodiment, the setting position of the first rotating shaft 270 is moved back by the connecting arm 250 to meet the assembly requirements with the drive swing arm 240. At the same time, it realizes the compact design of the handle base 210 in the inner and outer directions, avoids the excessive thickness of the handle base 210 from interfering with other components inside the body pillar 400, and also reduces the material usage of the handle base 210, achieving a lightweight and low-cost design. Furthermore, since the first drive segment 241 and the second drive segment 242 are set at an angle, the first drive segment 241 can better meet the adaptation requirements of the connecting arm 250, while the second drive segment 242 can effectively contact and adapt to the traction drive component 230. The segmentation of the drive swing arm 240 makes its structural design more flexible and more adaptable.

[0061] In practical implementation, to improve assembly reliability and operational stability, multiple base openings 211 are provided along the extension direction of the first rotating shaft 270, and a connecting arm 250 is provided on the upper and / or lower side of each base opening 211. Based on this, drive swing arms 240 are provided in a one-to-one correspondence with the base openings 211. The drive swing arms 240 that need to contact the traction drive component 230 adopt a segmented design with the first drive segment 241 and the second drive segment 242 cooperating. The remaining drive swing arms 240 do not require a segmented design, such as... Figure 9 As shown.

[0062] Optionally, the first drive section 241 is hinged to the connecting arm 250 near the second drive section 242 to extend the lever arm on the handle side, so that people outside the vehicle can turn the handle body 220 without applying too much force, making the opening and unlocking process smoother.

[0063] In some embodiments, see Figure 8 and Figure 9An elastic reset member 260 is provided between the pull drive member 230 and the handle base 210. The elastic reset member 260 is configured with a preload to bring the drive end of the pull drive member 230 closer to the door lock body 100. During the outward opening and unlocking process, the handle body 220 drives the drive swing arm 240 to rotate around the first pivot 270, and the drive swing arm 240 pushes the pull drive member 230 to rotate around the second pivot 280. The elastic reset member 260 deforms and its elastic potential energy increases. After the outward opening and unlocking process is completed, the person outside the vehicle removes the force applied to the handle body 220, and the elastic reset member 260 releases its elastic potential energy, causing the pull drive member 230 to reverse and reset. At the same time, the reverse rotation of the pull drive member 230 pushes the drive swing arm 240 and the handle body 220 to reset. This embodiment realizes the automatic reset of the outward opening handle 200, which is more convenient to use. At the same time, it simplifies the adaptation structure between the drive swing arm 240 and the pull drive member 230, which can be stably pushed against each other, making the structure simpler.

[0064] In addition, the elastic reset component 260 also requires the outward opening cable to have a certain amount of free extension and retraction during the design, with an extension and retraction stroke of about 20mm~30mm. This avoids the outward opening cable from getting stuck due to relative displacement (dynamic gap) between the vehicle body and the door caused by factors such as opening and closing the door and the torsion of the vehicle body during driving, thereby reducing the risk of wear and improving the reliability of use.

[0065] In practical implementation, the elastic reset element 260 is a torsion spring (such as...). Figure 8 and Figure 9 (As shown), tension springs, compression springs, etc., are not the only types mentioned here.

[0066] In some embodiments, see Figures 7 to 9 The traction drive component 230 has a driven arm 231 and multiple traction arms 232. The driven arm 231 and the multiple traction arms 232 are distributed at intervals around the rotation axis of the traction drive component 230, and the traction arms 232 form the driving end of the traction drive component 230. The driving end of the drive swing arm 240 contacts the driven arm 231 and drives the traction drive component 230 to rotate through the driven arm 231. The outward-opening traction component 300 is connected to one of the traction arms 232. This embodiment uses an extended arm-like structure to meet the adaptation of the drive swing arm 240 and the outward-opening traction component 300, reducing the material usage of the traction drive component 230 and achieving a lightweight design. At the same time, the setting position of the driven arm 231 and the multiple traction arms 232 can be more flexible, reducing the design difficulty of the traction drive component 230. Furthermore, since multiple towing arms 232 are provided, the traction drive component 230 can be flexibly selected to connect to which towing arm 232 according to the installation requirements such as vehicle model, making the traction drive component 230 more adaptable.

[0067] This embodiment exemplarily illustrates a scheme of setting two traction arms 232. It should be understood that the number and setting position of the traction arms 232 are determined according to actual installation requirements and are not limited here.

[0068] In some embodiments, see Figure 6 , Figure 8 and Figure 9 The free end of the driven arm 231 is bent to form a contact flange 2311, so as to increase the contact area between the driven arm 231 and the second drive section 242, thereby improving the reliability of the fit between the drive swing arm 240 and the traction drive member 230.

[0069] In some embodiments, see Figures 6 to 10 The end of the traction arm 232 is provided with a fixing member 2321 (e.g., a fixing clip) to connect with the outward-opening traction member 300.

[0070] Based on the same inventive concept, this application embodiment also provides a pillar structure assembly, including a vehicle body pillar 400 and the above-mentioned emergency door lock structure. The door lock body 100 in the emergency door lock structure is disposed in the inner cavity of the vehicle body pillar 400, and the outward opening handle 200 in the emergency door lock structure is disposed on the outer side of the vehicle body pillar 400.

[0071] Compared with the prior art, the column structure assembly provided in this application, by adopting the above-mentioned emergency door lock structure, effectively improves the smoothness of outward opening and unlocking, reduces the failure rate of the outward opening and unlocking process, and enhances the safety and reliability of use.

[0072] In some embodiments, see Figures 1 to 5 The outer panel of the vehicle body pillar 400 includes a lower extension section 410 of the roof outer panel and an upper extension section 422 of the sill beam outer panel. The lower edge of the lower extension section 410 of the roof outer panel connects with the upper edge of the upper extension section 422 of the sill beam outer panel. The outward-opening handle 200 is connected to the upper extension section 422 of the sill beam outer panel. The door lock body 100 is located on the inner side of the upper extension section 422 of the sill beam outer panel and is set corresponding to the connection gap between the lower extension section 410 of the roof outer panel and the upper extension section 422 of the sill beam outer panel. If the emergency door lock structure is set for the rear door, the lower extension section 410 of the roof outer panel corresponds to the rear quarter window area, which not only meets the needs of outward-opening rescue but also maintains the aesthetics of the vehicle body.

[0073] In this embodiment, the lower extension section 410 of the roof outer panel is integrally connected to the roof outer panel 500. The lower extension section 410 forms a pillar outer panel, improving the continuity between the pillar outer panel and the roof outer panel 500, thereby enhancing the aesthetics of the vehicle body side structure design. It also fully meets the assembly requirements of the outward-opening handle 200. Furthermore, the door lock body 100 is positioned within the space corresponding to the connection gap between the lower extension section 410 of the roof outer panel and the upper extension section 422 of the sill beam, bringing the outward-opening handle 200 closer to the door lock body 100 and minimizing the length of the outward-opening pull member 300.

[0074] In some embodiments, see Figure 5 The lower extension section 410 of the top cover outer plate has a handle mounting opening 411. The edge of the handle mounting opening 411 has a handle mounting lug 412. The handle mounting lug 412 can be connected to the handle base 210 by screws or other fasteners.

[0075] In some embodiments, the handle base 210 is provided with a mounting post, the mounting post having a screw hole, and the edge of the handle base 210 having a snap fastener. The snap fastener engages and positions with the edge of the handle mounting opening 411, and then locks with the handle mounting lug 412 through the screw hole on the mounting post.

[0076] In some embodiments, see Figures 1 to 5 The top of the lower extension section 410 of the roof cover is connected to the roof cover 500. The sill beam outer plate 420 includes the sill beam outer plate main body 421 and the sill beam outer plate extension section 422 located at the rear end of the sill beam main body 440. The door lock body 100 is located inside the sill beam outer plate extension section 422. The sill beam outer plate extension section 422 has a locking avoidance opening 430, which can cooperate with the locking point on the door to realize the locking and unlocking of the door.

[0077] Optionally, in some models, the front end of the sill beam outer panel body 421 is provided with a front upper extension section 423, making the sill beam outer panel 420 generally U-shaped, such as... Figure 1 As shown. Figure 1 The upper front extension 423 of the sill beam outer panel connects to the A-pillar, and the body pillar 400 formed by the lower extension 410 of the roof outer panel and the upper extension 422 of the sill beam outer panel is the B-pillar.

[0078] In some embodiments, see Figures 1 to 3The vehicle body also has a sill beam body 440, and the sill beam outer plate 420 is adapted to the shape of the sill beam body 440. The sill beam outer plate 420 and the sill beam body 440 are integrally formed hollow beams. The door lock body 100 is connected to the inner cavity of the sill beam body 440. The sill beam body 440 also has a locking avoidance opening 430. The locking avoidance opening 430 on the sill beam body 440 corresponds to the locking avoidance opening 430 on the sill beam outer plate 420. Figure 1 The example shown is a U-shaped sill beam body 440.

[0079] Optionally, the sill beam body 440 is provided with a door lock assembly hole 4401 for connecting the door lock body 100, and the sill beam outer plate 420 is provided with an assembly clearance hole 4201 corresponding to the door lock assembly hole 4401. The diameter of the assembly clearance hole 4201 is larger than the diameter of the door lock assembly hole 4401, so as to provide operating space for the assembly of the door lock body 100 and the sill beam body 440.

[0080] Based on the same inventive concept, this application also provides a vehicle including the above-described pillar structure assembly.

[0081] Compared with the prior art, the vehicle provided in this application improves the smoothness of emergency unlocking by adopting the above-mentioned pillar structure assembly, and reduces the failure rate, which is conducive to improving the reliability and safety of the vehicle and also enhances the overall quality of the vehicle.

[0082] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
