Description

Technical Field

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

[0002] Existing vehicle door lock reinforcement components must simultaneously meet the dual core requirements of strength and lightweighting. On the one hand, the reinforcement components must possess sufficient structural strength and fatigue resistance to withstand repeated impacts during the door lock opening and closing process, vibration loads during vehicle operation, and instantaneous forces in sudden collision scenarios, preventing door lock failure due to structural deformation or fracture, thereby avoiding safety hazards. On the other hand, as the requirements for driving range and energy consumption performance of new energy vehicles and energy-saving models continue to increase, vehicle lightweighting has become a core technological trend. As a non-load-bearing core component of the vehicle body, the weight optimization of the door lock installation reinforcement structure is of great significance for reducing vehicle energy consumption and improving driving range.

[0003] However, the design of vehicle door lock reinforcement components in existing technologies often fails to balance the requirements of strength and lightweighting. Traditional reinforcement components are mostly manufactured through stamping processes, and in order to increase local strength, additional reinforcing plates are usually added. Although the basic strength requirements are met, this results in a large weight for the reinforcement components, which cannot meet the development needs of vehicle lightweighting.

[0004] Another technology uses carbon fiber composites to replace traditional metal materials, but high-end composite materials such as carbon fiber have problems such as high cost, complex molding process, and poor compatibility with other parts of the vehicle body, making it difficult to achieve large-scale mass production. In addition, the structural design of some reinforcing components did not fully consider the synergy between door lock assembly precision and structural strength, which further limited the space for lightweight design while meeting assembly tolerance requirements. Utility Model Content

[0005] The purpose of this application is to provide a door lock mounting reinforcement structure, a door lock mounting assembly, and a vehicle, which aims to solve the problem that existing door lock mounting reinforcement structures cannot simultaneously meet the requirements of high strength and lightweight, while also being suitable for mass production.

[0006] In a first aspect, embodiments of this application provide a door lock mounting reinforcement structure, including: A reinforcing frame includes multiple reinforcing plates connected end-to-end, the multiple reinforcing plates enclosing a box-shaped structure with a buffer channel, and a fixing plate connected to the multiple reinforcing plates, the fixing plate covering the end of the buffer channel and used to provide a fixing position for the door lock mounting bracket; and The mounting mechanism includes a first mounting part and a second mounting part respectively connected to the reinforcing frame. The first mounting part is fixed to the vehicle body in the vertical direction, and the second mounting part is fixed to the vehicle body along a first path, which is parallel to the left-right or front-back direction.

[0007] The beneficial effects of the door lock mounting reinforcement structure provided in this application are as follows: Compared with the prior art, the reinforcement frame adopts a box-shaped structure with a buffer channel formed by multiple end-to-end reinforcing plates. The hollow buffer channel not only reduces the weight of the reinforcement frame, but also collapses to absorb energy after the door lock is subjected to force, effectively dispersing the forces under door lock opening and closing, vehicle vibration, and collision scenarios, avoiding deformation or fracture caused by local stress concentration, and improving the stability and reliability of the door lock assembly. Multiple reinforcing plates, in conjunction with the fixing plates located at the ends of the buffer channel, not only provide a fixing position for the door lock mounting frame, but also improve the overall strength and fatigue resistance through the mechanical properties of the box-shaped structure. At the same time, compared with the traditional plate structure, the box-shaped structure does not require additional reinforcing plates, reducing material usage while ensuring high strength, thus achieving structural lightweighting. Furthermore, the mounting mechanism is fixed to the vehicle body via a first mounting part along a vertical direction and a second mounting part along a first path parallel to the left-right or front-back direction, achieving fixation and limitation of the reinforcement frame in two directions, improving the stability of the reinforcement frame fixation. The overall structural design of this application is simple, does not require the use of expensive carbon fiber composite materials, has a simple molding process, and is suitable for large-scale mass production. It effectively solves the problem that existing door lock installation reinforcement structures cannot balance high strength, lightweight and mass production applicability.

[0008] In conjunction with the first aspect, in one possible implementation, the mounting mechanism includes a plurality of first mounting pieces spaced apart along a second path, and a plurality of second mounting pieces spaced apart along the second path, wherein the first mounting pieces form a first mounting portion, the second mounting pieces form a second mounting portion, and the second path is perpendicular to the first path.

[0009] In the above technical solution, multiple first mounting pieces are arranged along the second path to form multi-point force, which can make the fixing force of the first mounting part more uniform in the vertical direction, avoid installation loosening or structural damage caused by single-point force, and improve the stability of the connection with the vehicle body; multiple second mounting pieces are simultaneously distributed along the second path, and are fixed along the first path parallel to the left and right or front and back directions, forming a two-way multi-point installation structure together with the first mounting pieces, further enhancing the overall installation's vibration resistance and deformation resistance, and effectively dispersing the vibration force generated during vehicle driving and door lock operation.

[0010] In conjunction with the first aspect, in one possible implementation, the fixing plate includes a first fixing part and a second fixing part distributed at an angle, the first fixing part or the second fixing part being used to provide a fixing position for the door lock mounting bracket.

[0011] In the above technical solution, the first fixing part and the second fixing part are distributed at an angle, which improves the overall strength and deformation resistance compared with the flat structure. At the same time, it can also distribute the load transmitted to the first fixing plate during the opening and closing of the door lock and the shaking of the vehicle, avoid fatigue damage caused by the concentrated force of the flat structure, and further enhance the stability and service life of the door lock assembly.

[0012] In conjunction with the first aspect, in one possible implementation, the reinforcing plate has a weight-reducing hole communicating with the buffer channel.

[0013] In the above technical solution, the weight-reducing holes reduce the overall weight of the reinforcing frame without damaging its box-like structure, which is beneficial to achieving the vehicle's lightweight requirements. Simultaneously, the weight-reducing holes are connected to the buffer channel, guiding the load along the outer edge of the holes. Furthermore, the edge area of ​​the reinforcing plate is connected to adjacent reinforcing plates, resulting in greater structural strength and avoiding structural damage caused by concentrated load transfer.

[0014] In conjunction with the first aspect, in one possible implementation, the fixing plate has a lightweight hole communicating with the buffer channel.

[0015] In the above technical solution, the lightweight hole is connected to the buffer channel, which not only reduces the overall weight of the reinforcing frame and helps to meet the lightweight requirements of the whole vehicle, but also ensures that the fixing plate located in the surrounding area of ​​the lightweight hole can provide a fixing position for the door lock mounting bracket.

[0016] Secondly, embodiments of this application also provide a door lock mounting assembly, including the aforementioned door lock mounting reinforcement structure and a crossbeam connecting the first mounting portion and the second mounting portion.

[0017] The beneficial effects of the door lock mounting assembly provided in this application are as follows: Compared with the prior art, it adopts the aforementioned door lock mounting reinforcement structure. The crossbeam connects both the first and second mounting parts, constructing multiple force transmission paths from the reinforcement frame to the crossbeam. This allows the loads generated by door lock opening and closing, vehicle vibration, and collisions to be evenly and quickly distributed and transmitted, improving the overall structural strength, deformation resistance, and fatigue resistance. The reinforcement frame uses multiple end-to-end reinforcing plates to form a box-shaped structure with a buffer channel. The hollow buffer channel not only reduces the weight of the reinforcement frame but also collapses to absorb energy after the door lock is subjected to force, effectively dispersing the forces under door lock opening and closing, vehicle vibration, and collision scenarios, avoiding deformation or fracture caused by local stress concentration, and improving the stability and reliability of the door lock assembly. Multiple reinforcing plates, in conjunction with the fixing plates located at the ends of the buffer channel, not only provide a fixing position for the door lock mounting frame but also improve the overall strength and fatigue resistance through the stability of the box-shaped structure. At the same time, compared with the traditional plate structure, the box-shaped structure does not require additional reinforcing plates, reducing material usage while ensuring high strength, and achieving structural lightweighting. Furthermore, the installation mechanism is fixed to the vehicle body via a first mounting part along a vertical direction and a second mounting part along a first path parallel to the left-right or front-back direction, achieving fixation and limiting of the reinforcing frame in two directions, thus improving the stability of the reinforcing frame fixation. The overall structural design of this application is simple, eliminating the need for costly carbon fiber composite materials, simplifying the molding process, and adapting to the needs of mass production. It effectively solves the problem that existing door lock installation reinforcement structures struggle to balance high strength, lightweight design, and mass production applicability.

[0018] In conjunction with the second aspect, in one possible implementation, the crossbeam has multiple reinforcing cavities distributed from top to bottom.

[0019] In the above technical solution, multiple reinforcing cavities are arranged in layers along the vertical direction, which improves the bending stiffness and torsional strength of the crossbeam, effectively enhancing its load-bearing capacity and deformation resistance, and enabling it to more stably bear and distribute the load transmitted by the door lock. At the same time, multiple reinforcing cavities allow the crossbeam to form multiple force transmission paths when under stress, avoiding local stress concentration, further improving the structure's fatigue resistance, and extending the service life of the assembly.

[0020] In conjunction with the second aspect, in one possible implementation, the crossbeam includes: The beam structure has a continuous reinforced channel; A partition plate, disposed within the reinforcing channel and connected to the beam, divides the reinforcing channel from top to bottom into multiple independent reinforcing cavities; and A reinforcing plate is disposed within the reinforcing cavity and is set at an angle to the partition plate, the reinforcing plate dividing the reinforcing cavity into multiple independent compartments.

[0021] In the above technical solution, the reinforcing plate further divides the reinforcing cavity, forming a supporting structure within the cavity to enhance the strength and deformation resistance of the crossbeam, preventing deformation or fatigue cracking caused by uneven stress in a single cavity. Simultaneously, the reinforcing plate also increases the force transmission path, effectively dispersing localized concentrated loads generated by door lock opening and closing, vehicle vibration, and collisions, accelerating the transfer of loads to the vehicle body, and preventing crossbeam damage due to stress concentration.

[0022] In conjunction with the second aspect, in one possible implementation, the reinforcing plate, the first mounting portion, and the beam form a first force transmission path, the connection between the second mounting portion and the reinforcing plate corresponds to the end of the reinforcing plate, and the reinforcing plate and the reinforcing plate form a second force transmission path.

[0023] In the above technical solution, the first force transmission path stably transmits the load to the beam along the continuous structure and quickly disperses the load along the crossbeam to avoid local stress concentration; the second force transmission path directly introduces the load into the partition chamber inside the beam through the reinforcing plate to realize the directional transmission and step-by-step buffering of the load.

[0024] Thirdly, embodiments of this application also provide a vehicle including the aforementioned door lock mounting assembly.

[0025] The beneficial effect of the vehicle provided in this application is that, compared with the prior art, it adopts the above-mentioned door lock mounting assembly, which has similar technical effects to the above-mentioned door lock mounting assembly, and will not be described in detail here.

[0034] Please refer to the following: Figures 1 to 4The present application describes the door lock mounting reinforcement structure, door lock mounting assembly, and vehicle provided. The door lock mounting reinforcement structure includes a reinforcement frame 1 and a mounting mechanism 2. The reinforcement frame 1 includes multiple reinforcing plates 101 connected end-to-end, forming a box-shaped structure with a buffer channel. It also includes a fixing plate 102 connected to the multiple reinforcing plates 101, which covers the end of the buffer channel and provides a fixing position for the door lock mounting frame 4. The mounting mechanism 2 includes a first mounting part 201 and a second mounting part 202 respectively connected to the reinforcement frame 1. The first mounting part 201 is fixed to the vehicle body in a vertical direction, and the second mounting part 202 is fixed to the vehicle body along a first path parallel to the left-right or front-back direction.

[0035] Compared with the prior art, the door lock mounting reinforcement structure provided in this application uses multiple end-to-end reinforcing plates 101 to form a box-shaped structure with a buffer channel. The hollow buffer channel not only reduces the weight of the reinforcement frame 1, but also collapses to absorb energy after the door lock is subjected to force, effectively dispersing the forces under door lock opening and closing, vehicle vibration, and collision scenarios, avoiding deformation or fracture caused by local stress concentration, and improving the stability and reliability of the door lock assembly. The multiple reinforcing plates 101, together with the fixing plates 102 located at the ends of the buffer channel, not only provide a fixing position for the door lock mounting frame 4, but also improve the overall strength and fatigue resistance through the stability of the box-shaped structure. At the same time, compared with the traditional plate structure, the box-shaped structure does not require additional reinforcing plates, reducing material usage while ensuring high strength, and achieving structural lightweighting. In addition, the mounting mechanism 2 is fixed to the vehicle body through the first mounting part 201 along the vertical direction and the second mounting part 202 along a first path parallel to the left-right direction or the front-back direction, realizing the fixation and limiting of the reinforcement frame 1 in two directions, improving the stability of the reinforcement frame 1. The overall structural design of this application is simple, does not require the use of expensive carbon fiber composite materials, has a simple molding process, and is suitable for large-scale mass production. It effectively solves the problem that existing door lock installation reinforcement structures cannot balance high strength, lightweight and mass production applicability.

[0036] Optionally, the first fixing part 1021 and the second fixing part 1022 are welded, snapped, screwed or riveted to the vehicle body.

[0037] Optionally, multiple reinforcing plates 101 and fixing plates 102 are formed into plate-like structures by stamping, then bent into box-like structures, and finally fixed by welding.

[0038] Optionally, the first fixing part 1021 and the second fixing part 1022 are respectively provided with mounting holes. The fixing parts are first welded to the vehicle body, and then bolts are inserted into the through holes and mounting holes of the vehicle body to achieve locking. The dual fixing method improves the stability and reliability of the connection between the first fixing part 1021, the second fixing part 1022 and the vehicle body.

[0039] Optionally, the fixing plate 102 has a first positioning area 1024, which corresponds to the second positioning area on the door lock mounting bracket 4, thereby achieving the assembly positioning of the door lock mounting bracket 4. The first positioning area 1024 and the second positioning area can be inserted for positioning or docked for positioning. For example, the fixing plate 102 has a first positioning groove, and the door lock mounting bracket 4 has a second positioning groove, or the fixing plate 102 has a first positioning protrusion, and the door lock mounting bracket 4 has a second positioning protrusion. The first positioning groove or the first positioning protrusion forms the first positioning area 1024, and the second positioning groove or the second positioning protrusion forms the second positioning area. When the first positioning area 1024 and the second positioning area correspond to each other (dock), the positioning of the door lock mounting bracket 4 and the fixing plate 102 is completed. Alternatively, a positioning hole can be opened on the fixing plate 102, and the door lock mounting bracket 4 has a positioning block. The positioning hole forms the first positioning area 1024, and the positioning block forms the second positioning area. The positioning block is inserted into the positioning hole to achieve the positioning of the fixing plate 102 and the door lock mounting bracket 4.

[0040] Please see Figures 1 to 2 In some embodiments, the mounting mechanism 2 includes a plurality of first mounting pieces spaced apart along a second path and a plurality of second mounting pieces spaced apart along the second path, wherein the first mounting pieces form the first mounting portion 201 and the second mounting pieces form the second mounting portion 202, and the second path is perpendicular to the first path.

[0041] Multiple first mounting pieces are arranged along the second path to form multi-point force distribution, which makes the fixing force on the first mounting part 201 more uniform in the vertical direction, avoiding installation loosening or structural damage caused by single-point force, and improving the stability of the connection with the vehicle body. Multiple second mounting pieces are simultaneously distributed along the second path, and are fixed along the first path parallel to the left-right or front-back direction, forming a two-way multi-point installation structure together with the first mounting pieces. This further enhances the overall installation's vibration resistance and deformation resistance, and effectively disperses the vibration force generated during vehicle driving and door lock operation. At the same time, compared with setting multiple first mounting pieces or multiple second mounting pieces as an integral long strip structure, this solution reduces the weight of the overall structure while achieving multi-point installation, which is conducive to the lightweighting of the vehicle.

[0042] Please see Figures 1 to 2In some embodiments, in one possible implementation, the fixing plate 102 includes a first fixing part 1021 and a second fixing part 1022 distributed at an angle, the first fixing part 1021 or the second fixing part 1022 being used to provide a fixing position for the door lock mounting bracket 4.

[0043] The first fixing part 1021 and the second fixing part 1022 are arranged at an angle, which improves the overall strength and resistance to deformation compared to a flat structure. It also disperses the load transmitted to the first fixing plate 102 during door lock opening and closing and vehicle shaking, avoiding fatigue damage caused by concentrated stress in a flat structure, and further enhancing the stability and service life of the door lock assembly. Furthermore, this solution eliminates the need for additional reinforcing and force-transmitting components, simplifying the assembly process, reducing production and adaptation costs, and minimizing weight gain from redundant structures, thus balancing lightweight requirements with structural reliability.

[0044] Optionally, the included angle between the first fixing part 1021 and the second fixing part 1022 forms a reinforcing zone. The corresponding reinforcing plate 101 has a connecting part adapted to the reinforcing zone. The connecting part is inserted into the reinforcing zone and connected to the first fixing part 1021 and the second fixing part 1022. The connecting part is inserted into the reinforcing zone formed by the included angle, forming a multi-faceted fit with the first fixing part 1021 and the second fixing part 1022. This increases the contact area, which not only improves the reliability of the connection and effectively reduces the load per unit area, but also forms a continuous force transmission path. This allows the loads generated by door lock opening and closing, vehicle vibration, and collisions to be quickly transmitted to the vehicle body along the aforementioned force transmission path, accelerating the load dispersion speed, avoiding local stress concentration, and enhancing the stability and service life of the door lock assembly.

[0045] Please see Figures 1 to 2 In some embodiments, the reinforcing plate 101 has a weight-reducing hole 1011 communicating with the buffer channel.

[0046] The weight-reducing hole 1011 reduces the overall weight of the reinforcing frame 1 without compromising its boxed structure, thus facilitating the vehicle's lightweight design. Simultaneously, the weight-reducing hole 1011 connects to the buffer channel, guiding load transfer along its outer edge. Furthermore, the edge area of ​​the reinforcing plate 101 connects to adjacent reinforcing plates 101, resulting in high structural strength and preventing structural damage caused by concentrated load transfer. Moreover, the weight-reducing hole 1011 requires no complex manufacturing process and can be completed simultaneously with the stamping process of the reinforcing plate 101, without adding extra production steps or costs, thus balancing lightweight design, structural reliability, and the demands of mass production.

[0047] Optionally, the weight reduction hole 1011 is located in the middle area of ​​the reinforcing plate 101.

[0048] Please see Figures 1 to 2 In some embodiments, the fixing plate 102 has a lightweight hole 1023 communicating with the buffer channel.

[0049] The lightweight hole 1023 is connected to the buffer channel, which not only reduces the overall weight of the reinforcing frame 1, which is conducive to achieving the lightweight requirements of the whole vehicle, but also ensures that the fixing plate 102 located in the surrounding area of ​​the lightweight hole 1023 can provide a fixing position for the door lock mounting bracket 4.

[0050] Based on the same inventive concept, please refer to Figures 3 to 4 This application embodiment also provides a door lock mounting assembly, including the above-mentioned door lock mounting reinforcement structure, and a crossbeam 3 connected to the first mounting part 201 and the second mounting part 202.

[0051] The door lock mounting assembly provided by this utility model adopts the aforementioned door lock mounting reinforcement structure. The crossbeam 3 connects the first mounting part 201 and the second mounting part 202, constructing multiple force transmission paths from the reinforcement frame 1 to the crossbeam 3. This allows the loads generated by door lock opening and closing, vehicle vibration, and collisions to be evenly and quickly distributed and transmitted, improving the overall structural strength, deformation resistance, and fatigue resistance. The reinforcement frame 1 uses multiple end-to-end reinforcing plates 101 to form a box-shaped structure with a buffer channel. The hollow buffer channel not only reduces the weight of the reinforcement frame 1 but also collapses to absorb energy after the door lock is subjected to force, effectively dispersing the forces under door lock opening and closing, vehicle vibration, and collision scenarios, avoiding deformation or fracture caused by local stress concentration, and improving the stability and reliability of the door lock assembly. The multiple reinforcing plates 101, in conjunction with the fixing plates 102 located at the ends of the buffer channel, not only provide a fixing position for the door lock mounting frame 4 but also improve the overall strength and fatigue resistance through the stability of the box-shaped structure. Meanwhile, compared to traditional plate structures, the box-shaped structure eliminates the need for additional reinforcing plates, reducing material usage while maintaining high strength and achieving structural lightweighting. Furthermore, the mounting mechanism 2 is fixed to the vehicle body via a first mounting part 201 along a vertical direction and a second mounting part 202 along a first path parallel to the left-right or front-back direction, achieving fixation and limiting of the reinforcing frame 1 in two directions, thus improving the stability of the reinforcing frame 1. The overall structural design of this application is simple, eliminating the need for costly carbon fiber composite materials, simplifying the molding process, and adapting to mass production requirements. It effectively solves the problem that existing door lock installation reinforcement structures struggle to balance high strength, lightweighting, and mass production applicability.

[0052] It should be noted that the crossbeam 3 is located on the inner side of the upper edge of the opening of the vehicle's trunk (luggage compartment).

[0053] Please see Figures 3 to 4 In some embodiments, the crossbeam 3 has multiple reinforcing cavities distributed from top to bottom.

[0054] Multiple reinforcing cavities are arranged in layers along the vertical direction, which improves the bending stiffness and torsional strength of the crossbeam 3, effectively enhancing its load-bearing capacity and deformation resistance, and enabling it to more stably bear and distribute the load transmitted by the door lock. At the same time, multiple reinforcing cavities allow the crossbeam 3 to form multiple force transmission paths when under stress, avoiding local stress concentration, further improving the structure's fatigue resistance, and extending the service life of the assembly.

[0055] Please see Figures 3 to 4 In some embodiments, the crossbeam 3 includes a beam body 301, a partition plate 302, and a reinforcing plate 303. The beam body 301 has a through reinforcing channel. The partition plate 302 is disposed in the reinforcing channel and connected to the beam body 301. The partition plate 302 divides the reinforcing channel from top to bottom into multiple independent reinforcing cavities. The reinforcing plate 303 is disposed in the reinforcing cavity and is set at an angle to the partition plate 302. The reinforcing plate 303 divides the reinforcing cavity into multiple independent compartments 304.

[0056] The reinforcing plate 303 further divides the reinforcing cavity, forming a supporting structure within it to enhance the strength and deformation resistance of the crossbeam 3, preventing deformation or fatigue cracking caused by uneven stress in a single cavity. Simultaneously, the reinforcing plate 303 increases the force transmission path, effectively dispersing localized concentrated loads generated by door lock opening and closing, vehicle vibration, and collisions, accelerating the transfer of loads to the vehicle body, and preventing damage to the crossbeam 3 due to stress concentration.

[0057] Optionally, the reinforcing plate 303 is perpendicular to the partition plate 302.

[0058] Optionally, the reinforced cavity is provided with multiple reinforcing plates 303, the centers of the multiple reinforcing plates 303 intersect each other, and the opposite sides of each reinforcing plate 303 are connected to the partition plate 302 or the beam 301.

[0059] Please see Figures 3 to 4 In some embodiments, the reinforcing plate 101, the first mounting part 201 and the beam 301 form a first force transmission path, the connection between the second mounting part 202 and the reinforcing plate 101 corresponds to the end of the reinforcing plate 303, and the reinforcing plate 101 and the reinforcing plate 303 form a second force transmission path.

[0060] The first force transmission path stably transfers the load along the continuous structure to the beam 301 and rapidly disperses the load along the crossbeam 3, avoiding local stress concentration. The second force transmission path directly introduces the load into the partition chamber 304 inside the beam 301 through the reinforcing plate 303, achieving directional load transmission and step-by-step buffering. This solution avoids stress concentration caused by the low force transmission rate of a single path, improves the fatigue resistance and impact resistance of the door lock assembly, and enhances structural stability and service life. Furthermore, this solution requires no additional force transmission components, ensuring high-strength force transmission without increasing structural weight or production complexity, thus balancing lightweight requirements with applicability for large-scale mass production.

[0061] Based on the same inventive concept, this application also provides a vehicle. The vehicle includes the door lock mounting assembly described above.

[0062] The vehicle provided by this utility model adopts the aforementioned door lock mounting assembly. The crossbeam 3 connects the first mounting part 201 and the second mounting part 202, constructing multiple force transmission paths from the reinforcing frame 1 to the crossbeam 3. This allows the loads generated by door lock opening and closing, vehicle vibration, and collisions to be evenly distributed and transmitted within the assembly, significantly improving the overall structural strength, deformation resistance, and fatigue resistance. The reinforcing frame 1 is formed by multiple end-to-end reinforcing plates 101 enclosing a box-shaped structure with a buffer channel. The hollow buffer channel not only reduces the weight of the reinforcing frame 1 but also collapses to absorb energy after the door lock is subjected to force, effectively dispersing the forces under door lock opening and closing, vehicle vibration, and collision scenarios. This avoids deformation or fracture caused by local stress concentration, improving the stability and reliability of the door lock assembly. The multiple reinforcing plates 101, in conjunction with the fixing plates 102 located at the ends of the buffer channel, not only provide a fixing position for the door lock mounting frame 4 but also enhance the overall strength and fatigue resistance through the stability of the box-shaped structure. Meanwhile, compared to traditional plate structures, the box-shaped structure eliminates the need for additional reinforcing plates, reducing material usage while maintaining high strength and achieving structural lightweighting. Furthermore, the mounting mechanism 2 is fixed to the vehicle body via a first mounting part 201 along a vertical direction and a second mounting part 202 along a first path parallel to the left-right or front-back direction, achieving fixation and limiting of the reinforcing frame 1 in two directions, thus improving the stability of the reinforcing frame 1. The overall structural design of this application is simple, eliminating the need for costly carbon fiber composite materials, simplifying the molding process, and adapting to mass production requirements. It effectively solves the problem that existing door lock installation reinforcement structures struggle to balance high strength, lightweighting, and mass production applicability.

[0063] 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.
