Carriage handle assembly and vehicle

Abstract

The application provides a vehicle compartment handle assembly and a vehicle, and belongs to the technical field of vehicle handles. The vehicle compartment handle assembly comprises a base, a handle, and an opening rocker. When a user applies force to the driving part of the handle, the hinged part rotates around its own rotating shaft, drives the spherical or hemispherical rolling part on it to contact and apply force to the transmission part of the opening rocker. At this time, the rolling part rotates around its own spherical center, forms rolling friction between the two instead of traditional sliding friction. The friction of rolling friction is much smaller than that of sliding friction. Even if some dust and impurities invade, the wear degree of the transmission part and the hinged part can be greatly reduced, and the high-frequency abnormal sound problem caused by the double effects of insufficient lubrication and impurity invasion in the traditional structure is avoided.

Description

Technical Field

[0001] This application belongs to the field of vehicle handle technology, and more specifically, relates to a vehicle handle assembly and a vehicle. Background Technology

[0002] The cargo compartment handle, also known as the door opening handle, is a key functional component installed on the rear panel assembly of the cargo compartment. It is primarily used by the user to open the rear panel door from outside the vehicle. This assembly typically consists of an external handle body, an internal linkage mechanism (such as a rocker arm or cable), a lock cylinder, and a mounting base. By manipulating the handle, the user activates the internal linkage mechanism, releasing the door lock and allowing the rear panel of the cargo compartment to open smoothly.

[0003] The existing handle and internal rocker arm lack a long-term lubrication system for their transmission mating surfaces. After assembly, friction reduction relies solely on an initial small amount of grease, with no grease retention or replenishment mechanism. As opening and closing frequency increases, the grease is rapidly consumed, gradually leading to dry friction on the mating surfaces. Furthermore, when the vehicle travels on bumpy roads, dust and impurities accumulated inside the rear panel of the cargo box can easily penetrate the clearance between the handle and rocker arm, exacerbating wear and further compromising the residual lubrication. Since the handle directly rubs against both the rear panel sheet metal and the rocker arm, the rigid friction between the handle and the metal components, combined with insufficient lubrication and dust intrusion, generates high-frequency noise during each opening and closing operation.

[0004] After prolonged use, the mating surfaces of the handle and rocker arm experience significant increases in frictional resistance due to wear and dust accumulation. This results in persistent frictional noises between the handle and the sheet metal / rocker arm, which not only severely impacts the user's perception of the vehicle's performance but also accelerates the fatigue failure of the handle hinge components, shortens their lifespan, and increases the vehicle's subsequent maintenance costs. Utility Model Content

[0005] The purpose of this application is to provide a vehicle handle assembly and vehicle, which aims to solve the problem that long-term friction between the existing handle and rocker arm can easily cause continuous abnormal noise, affecting the comfort of vehicle use and shortening the service life of the handle.

[0006] In a first aspect, embodiments of this application provide a vehicle compartment handle assembly, including: A base for connecting to a vehicle door, the base having an installation through hole; The handle includes a drive unit and a hinge unit connected to the inner side of the drive unit, and a rolling part disposed on the hinge unit. The drive unit is located on the outer side of the base, and the hinge unit extends through the mounting hole into the inner side of the base and is hinged to the base. The rolling part is a spherical or hemispherical component that rotates around its own center. An opening rocker arm is located inside the base and rotatably connected to the base. The pivot of the hinge is perpendicular to the pivot of the opening rocker arm. The opening rocker arm has a transmission part that corresponds vertically to the rolling part. The driving part is subjected to force to rotate the hinge part, the rolling part applies force to the transmission part to drive the opening rocker arm to rotate, and at the same time the rolling part rotates on its own, generating rolling friction between the rolling part and the transmission part.

[0007] The beneficial effects of the vehicle handle assembly provided in this application are as follows: Compared with the prior art, when the user applies force to the drive part of the handle, the hinge part rotates around its own axis, causing the spherical or hemispherical rolling part on it to contact the transmission part of the opening rocker arm and apply force. At this time, the rolling part rotates around its own center, so that rolling friction is formed between the two instead of traditional sliding friction. Since the hinge part is inserted into the mounting through hole and the drive part is located on the outside of the base, the drive part and the hinge part can jointly seal the mounting through hole, improving the sealing performance of the base. Even when the vehicle is driving on bumpy roads, the probability of dust and impurities entering is reduced. In addition, the friction force of rolling friction itself is much smaller than that of sliding friction. Even if some dust and impurities enter, the wear on the transmission part and the hinge part can be greatly reduced, avoiding the high-frequency abnormal noise problem caused by insufficient lubrication and impurity intrusion in the traditional structure. Moreover, the rolling part and the transmission part form point contact, reducing the rigid friction loss between the handle and the base and the opening rocker arm, effectively delaying the fatigue failure rate of the hinge part, and significantly extending the service life of the entire handle assembly. This application optimizes the transmission friction, which not only improves the smoothness of the user's operation when opening the car door, but also eliminates friction noises during long-term use, improves the comfort and perceived quality of the vehicle, and reduces the need and cost of later maintenance due to component wear.

[0008] In conjunction with the first aspect, in one possible implementation, the vehicle handle assembly further includes a protective sleeve fitted over the hinge portion, the protective sleeve being used to prevent the hinge portion from rigidly contacting the transmission portion, and the protective sleeve having a clearance hole for avoiding the rolling portion.

[0009] In the above technical solution, the protective sleeve effectively prevents the hinge part from directly contacting the transmission part of the opening rocker arm, avoiding wear caused by rigid collision. The clearance holes on the protective sleeve precisely avoid the rolling part, allowing the rolling part to smoothly contact the transmission part and apply thrust during the rotation of the hinge part. This ensures that the rolling part rotates around its own center, forming rolling friction with the transmission part, thus ensuring the smoothness of the door opening operation.

[0010] In conjunction with the first aspect, in one possible implementation, the hinge portion has a receiving groove, the receiving groove is a hemispherical groove, a ball is rotatably disposed in the receiving groove, the ball forms the rolling portion, and the ball portion is located outside the receiving groove for contacting the transmission portion.

[0011] In the above technical solution, when the drive unit is subjected to force and drives the hinge unit to rotate, the balls in the receiving groove are partially exposed and contact the transmission part of the opening rocker arm. As the hinge unit rotates, the balls rotate within the receiving groove, transforming the sliding friction between the hinge unit and the transmission part into rolling friction between the balls and both. The hemispherical receiving groove stably limits the movement of the balls, ensuring that the balls always roll within a preset trajectory, avoiding abnormal wear caused by component misalignment during transmission, and reducing high-frequency abnormal noise caused by friction.

[0012] In conjunction with the first aspect, in one possible implementation, the opening of the rocker arm includes: A hinged plate, rotatably connected to the base; and Multiple transmission arms are radially connected to the hinge plate, and the free end of one of the transmission arms is bent to form a transmission area, which is used to contact the rolling part. The transmission arm having the transmission area forms the transmission part.

[0013] In the above technical solution, multiple transmission arms are integrated onto the hinge plate, allowing them to rotate synchronously with the hinge plate. This ensures the smoothness of the overall rotation of the rocker arm. The curved transmission area increases the contact area with the rolling part, creating a close contact and preventing slippage or deviation of the rolling part during force application, thus achieving stable force transmission. The curved transmission area can also distribute the pressure applied by the rolling part through structural optimization, reducing localized wear. Combined with the rolling friction characteristics of the rolling part, this further reduces component wear.

[0014] In conjunction with the first aspect, in one possible implementation, the base has a limiting plate on its inner side, the opening rocker arm has a limiting part corresponding to the limiting plate, when the handle is not under force, the limiting part abuts against the limiting plate, and when the handle is under force, the limiting part moves away from the limiting plate. The vehicle handle assembly also includes an elastic element, which is configured with a preload force to keep the limiting part abutting against the limiting plate.

[0015] In the above technical solution, when the handle is not under force, the preload of the elastic element ensures that the limiting part is stably abutted against the limiting plate, limiting the initial position of the opening rocker arm. This prevents the opening rocker arm from wobbling due to lack of restraint when the vehicle is bumpy, thus avoiding collisions with surrounding components and abnormal noise. When force is applied to the drive part of the handle, causing the hinge and rolling parts to drive the opening rocker arm to rotate, the limiting part will move away from the limiting plate, and the elastic element will deform and store force accordingly. When the force is stopped from the drive part, the elastic element releases the stored force, which will drive the limiting part to automatically reset and abut against the limiting plate again, causing the opening rocker arm and handle to return to their initial positions. This eliminates the need for manual reset and improves operational convenience.

[0016] In conjunction with the first aspect, in one possible implementation, the handle includes: The handle body is located on the outside of the base, and the handle body has a receiving groove, forming the drive part; A connecting arm, connected to the handle body, extends through the mounting hole into the inner side of the base; the handle body covers the mounting hole and, together with the connecting arm, isolates the mounting hole from the outside; the connecting arm is hinged to the base; and An extension arm is connected to the connecting arm and extends inward to the connecting arm. The extension arm and the connecting arm together form the hinge portion, and the rolling portion is connected to the extension arm.

[0017] In the above technical solution, the handle body is located on the outside of the base and covers the mounting hole of the base. Together with the connecting arm that extends through the mounting hole into the inside of the base, the two isolate the mounting hole from the external environment, effectively preventing rainwater, dust, mud, and other impurities from entering the base through the mounting hole. This prevents these impurities from adhering to the surfaces of transmission components such as the rocker arm and rolling part, avoiding transmission obstruction or accelerated component wear. The connecting arm and the extension arm extending inward together form a hinge, and the rolling part is connected to the extension arm, allowing the rolling part to precisely align with the transmission part of the rocker arm. When the connecting arm rotates with the handle body, the extension arm can drive the rolling part to contact and apply force to the transmission part, ensuring that power transmission remains consistent.

[0018] In conjunction with the first aspect, in one possible implementation, the inner plate of the base is provided with a plurality of mounting buckles, the plurality of mounting buckles being distributed along the circumference of the base, and the vehicle door handle assembly further includes a sealing strip surrounding the circumference of the base, the sealing strip engaging with the mounting buckles, and the sealing strip being used to seal the gap between the base and the vehicle door.

[0019] In the aforementioned technical solution, once the base and the car door are connected, the sealing strip tightly fills the gap between them. During vehicle operation, this effectively prevents rainwater, road mud, and dust from seeping into the base through the gap, thus avoiding transmission jamming or accelerated component wear, creating a clean and stable working environment for the internal transmission mechanism. It also reduces external noise entering the vehicle through the gap, improving the quietness of the ride. Furthermore, during repeated opening and closing of the car door, the base will vibrate slightly due to the force applied, and the elasticity of the sealing strip can buffer the vibration and impact between the base and the car door, reducing abnormal noises caused by rigid collisions.

[0020] In conjunction with the first aspect, in one possible implementation, the hinge portion has a plurality of sequentially distributed reinforcing ribs, with adjacent reinforcing ribs spaced apart.

[0021] In the above technical solution, when the user applies force to the drive part of the handle, causing the hinge part to rotate around the hinge point with the base, and drives the rocker arm to open through the rolling part, the hinge part needs to withstand the tension from the drive part, the reaction force transmitted by the rolling part, and the impact load when the vehicle is bumpy. The multiple sequentially distributed reinforcing ribs increase the strength of the hinge part and can disperse these forces, improve the overall structural rigidity and deformation resistance of the hinge part, avoid fatigue damage such as bending and breakage of the hinge part due to long-term stress, and ensure the stable and reliable power transmission process.

[0022] In conjunction with the first aspect, in one possible implementation, the inner plate of the base is provided with a connecting post, the connecting post has a connecting hole for connecting with the vehicle body, and the outer peripheral surface of the connecting post is provided with a plurality of radially distributed reinforcing plates.

[0023] In the above technical solution, the radially distributed reinforcing plates tightly connect the connecting column to the inner plate of the base, increasing the contact area between the connecting column and the base. This avoids breakage or loosening due to concentrated force when the connecting column is connected to the base through only a single root, ensuring the long-term stability of the connection between the base and the vehicle body, and preventing the base from shaking or shifting when the vehicle is bumpy.

[0024] Secondly, embodiments of this application also provide a vehicle including the passenger compartment handle assembly described in any of the above claims.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Specifically, the front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", and the bottom of the vehicle represents "down".

[0033] In addition, the front-rear direction of the vehicle body as defined in the embodiments of this application refers to the front-rear direction of the vehicle's forward direction during driving; the left-right direction of the vehicle body as defined refers to the left-right direction of the vehicle's forward direction during driving; and the up-down direction of the vehicle body as defined refers to the up-down direction of the vehicle's forward direction during driving.

[0034] Please refer to the following: Figures 1 to 4 The present application describes the vehicle door handle assembly and the vehicle provided. The vehicle door handle assembly includes a base 1, a handle 2, and an opening rocker arm 3. The base 1 is used to connect with the vehicle door and has a mounting through hole. The handle 2 includes a drive part 201 and a hinge part 202 connected to the inner side of the drive part 201, and also includes a rolling part 203 disposed on the hinge part 202. The drive part 201 is located on the outer side of the base 1, and the hinge part 202 extends through the mounting through hole into the inner side of the base 1 and is hinged to the base 1. The rolling part 203 is a spherical or hemispherical component that rotates around its own center. The opening rocker arm 3 is disposed on the inner side of the base 1 and is rotatably connected to the base 1. The rotation axis of the hinge part 202 is perpendicular to the rotation axis of the opening rocker arm 3, and the opening rocker arm 3 has a transmission part that corresponds vertically to the rolling part 203. When the drive unit 201 is subjected to force, the hinge unit 202 rotates. The rolling part 203 applies force to the transmission unit to drive the rocker arm 3 to rotate. At the same time, the rolling part 203 rotates on its own, generating rolling friction between the rolling part 203 and the transmission unit.

[0035] Compared with the prior art, the handle assembly provided in this application, when the user applies force to the drive part 201 of the handle 2, the hinge part 202 rotates around its own axis, causing the spherical or hemispherical rolling part 203 on it to contact the transmission part of the opening rocker arm 3 and apply force. At this time, the rolling part 203 rotates around its own center, so that rolling friction is formed between the two instead of traditional sliding friction. Since the hinge part 202 is inserted into the mounting through hole and the drive part 201 is located on the outside of the base 1, the drive part 201 and the hinge part 202 can jointly seal the mounting through hole, improve the sealing performance of the base 1, and reduce the probability of dust and impurities entering even when the vehicle is driving on a bumpy road. In addition, the friction force of rolling friction itself is much smaller than that of sliding friction. Even if some dust and impurities enter, the wear on the transmission part and the hinge part 202 can be greatly reduced, avoiding the high-frequency abnormal noise problem caused by insufficient lubrication and impurity intrusion in the traditional structure. Furthermore, the rolling part 203 forms point contact with the transmission part, reducing rigid frictional loss between the handle 2 and the base 1 and the opening rocker arm 3, effectively delaying the fatigue failure rate of the hinge part 202, and significantly extending the service life of the entire handle assembly. By optimizing the transmission friction form, this application not only improves the smoothness of the user's operation when opening the car door, but also eliminates frictional noises during long-term use, improving the comfort and perceived quality of vehicle use, while reducing the need and cost of later maintenance due to component wear.

[0036] It should be noted that in this application, "outer side" refers to the side of the base opposite to the opening rocker arm, while "inner side" is the opposite of "outer side". The solution in this application can be applied to the inner handle assembly or the outer handle assembly of a vehicle, without specific limitation.

[0037] It should be noted that, please participate Figure 3 When the rolling part 203 is a hemispherical component, when the driving part 203 is not under force, the plane of the transmission part in contact with the rolling part 203 is not perpendicular to the axis of rotation of the hinge part 202. Therefore, when the driving part 203 is under force, the rolling part 203 applies pressure to the transmission part and rotates around its own axis, thereby generating rolling friction.

[0038] Please see Figures 1 to 3 In some embodiments, the vehicle handle assembly also includes a protective sleeve 5 fitted over the hinge portion 202. The protective sleeve 5 is used to prevent the hinge portion 202 from rigidly contacting the transmission portion, and the protective sleeve 5 has a clearance hole for avoiding the rolling portion 203.

[0039] When force is applied to the drive part 201 of the handle 2, causing the hinge part 202 to rotate around the hinge point with the base 1, the protective sleeve 5 effectively prevents the hinge part 202 from directly contacting the transmission part of the opening rocker arm 3, avoiding wear caused by rigid collision between the two. It also mitigates the impact between components when the vehicle is bumpy, reducing the possibility of abnormal noise caused by rigid contact. The clearance hole on the protective sleeve 5 precisely avoids the rolling part 203, allowing the rolling part 203 to smoothly contact the transmission part and apply thrust during the rotation of the hinge part 202. This ensures that the rolling part 203 rotates around its own center, forming rolling friction with the transmission part, guaranteeing smooth door opening operation.

[0040] Optionally, the protective sleeve 5 is a flexible component, such as a rubber component or an EVA component.

[0041] Please see Figure 2 and Figure 4 In some embodiments, the hinge portion 202 has a receiving groove, which is a hemispherical groove. A ball is rotatably disposed in the receiving groove, forming a rolling portion 203. The ball portion is located outside the receiving groove for contacting the transmission portion.

[0042] When the drive unit 201 is subjected to force, it drives the hinge unit 202 to rotate. The balls in the receiving groove, being partially exposed, contact the transmission part of the opening rocker arm 3. As the hinge unit 202 rotates, the balls rotate within the receiving groove, transforming the sliding friction between the hinge unit 202 and the transmission part into rolling friction between the balls and both. Compared to sliding friction, rolling friction significantly reduces frictional force, thus decreasing wear between components. The hemispherical receiving groove stably limits the movement of the balls, ensuring they always roll within a preset trajectory, preventing abnormal wear caused by component misalignment during transmission, and reducing high-frequency noise generated by friction. Furthermore, the point contact between the balls and the transmission part reduces the contact area, and the ball rotation effectively cushions the impact between the hinge unit 202 and the transmission part during vehicle bumps, further protecting the mating surfaces, slowing down component fatigue failure, and extending the service life of the entire handle assembly.

[0043] Please see Figures 1 to 3 In some embodiments, the rocker arm 3 includes a hinge plate 301 and a plurality of transmission arms 302. The hinge plate 301 is rotatably connected to the base 1. The plurality of transmission arms 302 are radially connected to the hinge plate 301. The free end of one of the transmission arms 302 is bent to form a transmission area 3021. The transmission area 3021 is used to contact the rolling part 203. The transmission arm 302 with the transmission area 3021 forms a transmission part.

[0044] Multiple transmission arms 302 are integrated on the hinge plate 301 and can rotate synchronously with the hinge plate 301, ensuring the overall smooth rotation of the opening rocker arm 3. The curved transmission area 3021 increases the contact area with the rolling part 203, forming a close contact state and preventing the rolling part 203 from slipping or deviating during force application, thus achieving stable force transmission. The synchronous rotation of multiple radially distributed transmission arms 302 not only avoids lag in force transmission and enables the linkage of multiple locking mechanisms (such as side locks, center locks, etc.), but also simplifies the linkage structure inside the door by connecting different transmission arms 302 to corresponding pull cables or rods without the need for additional transmission components. In addition, the curved transmission area 3021 can disperse the pressure applied by the rolling part 203 through structural optimization, reducing local wear. Combined with the rolling friction characteristics of the rolling part 203, it further reduces component wear and extends the service life of the opening rocker arm 3.

[0045] It should be noted that at least two of the multiple transmission arms 302 are connected to the locking structure of the door via a connecting rod or a zipper to enable the opening or locking of the locking structure. The prior art's use of a transmission mechanism (opening rocker arm 3 and connecting rod or zipper) to link the handle 2 with the door locking structure is a conventional technique and not the focus of this application; therefore, it will not be elaborated upon further.

[0046] Please see Figure 1 and Figure 3 In some embodiments, the inner side of the base 1 has a limiting piece 104, and the opening rocker arm 3 has a limiting part 303 corresponding to the limiting piece 104. When the handle 2 is not under force, the limiting part 303 abuts against the limiting piece 104. After the handle 2 is under force, the limiting part 303 moves away from the limiting piece 104. The vehicle handle assembly also includes an elastic member, which is configured with a preload force to keep the limiting part 303 and the limiting piece 104 in abutment.

[0047] When the handle 2 is not under force, the preload of the elastic element ensures that the limiting part 303 is stably abutted against the limiting plate 104, limiting the initial position of the opening rocker arm 3. This prevents the opening rocker arm 3 from wobbling due to lack of restraint when the vehicle is bumpy, thus avoiding collisions with surrounding components and abnormal noises. When force is applied to the drive part 201 of the handle 2, driving the hinge part 202 and the rolling part 203 to rotate the opening rocker arm 3, the limiting part 303 will move away from the limiting plate 104, and the elastic element will deform and store force accordingly. When the force is stopped from the drive part 201, the elastic element releases the stored force, driving the limiting part 303 to automatically reset and re-abut against the limiting plate 104, causing the opening rocker arm 3 and the handle 2 to return to their initial positions. This eliminates the need for manual reset, improving operational convenience. In addition, the preload of the elastic element can also buffer the impact force during the rotation of the opening rocker arm 3, reducing rigid collisions when the limiting part 303 abuts against the limiting plate 104, reducing component wear, and extending the service life of the entire handle assembly.

[0048] Optionally, the elastic element is a torsion spring, with one end fixed to the base 1 and the other end fixed to the opening rocker arm 3.

[0049] Optionally, the rocker arm 3 has a fixing hole, and the end of the torsion spring is inserted into the fixing hole and engaged with the rocker arm 3.

[0050] Please see Figure 1 and Figure 2 In some embodiments, the handle 2 includes a handle body, a connecting arm, and an extension arm. The handle body is located on the outside of the base 1 and has a receiving groove 2011. The handle body forms a driving part 201. The connecting arm is connected to the handle body and extends into the inside of the base 1 through the mounting hole. The handle body covers the mounting hole and, together with the connecting arm, isolates the mounting hole from the outside. The connecting arm is hinged to the base 1. The extension arm is connected to the connecting arm and extends inward to the connecting arm. The extension arm and the connecting arm together form a hinge part 202. A rolling part 203 is connected to the extension arm.

[0051] The handle body is located on the outside of the base 1 and covers the mounting hole of the base 1. Together with the connecting arm that extends into the inside of the base 1 through the mounting hole, the two isolate the mounting hole from the external environment, effectively preventing rainwater, dust, mud and other impurities from entering the interior of the base 1 through the mounting hole. This prevents these impurities from adhering to the surfaces of transmission components such as the opening rocker arm 3 and the rolling part 203, avoiding transmission obstruction or accelerated wear of components, and providing a clean working environment for the internal transmission mechanism. The connecting arm and the extension arm extending inward together form the hinge part 202, and the rolling part 203 is connected to the extension arm, so that the rolling part 203 can accurately correspond to the transmission part of the opening rocker arm 3. When the connecting arm rotates with the handle body, the extension arm can drive the rolling part 203 to contact the transmission part and apply force, ensuring that the power transmission is not deviated and ensuring smooth door opening operation.

[0052] Optionally, the handle body, connecting arm, and extension arm can be integrated into a single component, improving overall strength.

[0053] Please see Figure 1 and Figure 3 In some embodiments, the inner plate of the base 1 is provided with a plurality of mounting buckles 101, which are distributed around the circumference of the base 1. The vehicle handle assembly also includes a sealing strip 4 surrounding the circumference of the base 1. The sealing strip 4 engages with the mounting buckles 101 and is used to seal the gap between the base 1 and the vehicle door.

[0054] The evenly distributed mounting clips 101 along the circumference provide a stable and balanced fixing force for the sealing strip 4, ensuring that the sealing strip 4 fits tightly against the edge of the base 1. This avoids the problem of local lifting and falling off caused by uneven fixing in traditional sealing structures, improving the reliability and efficiency of the sealing strip 4 assembly. After the base 1 is connected to the door, the sealing strip 4 will tightly fill the gap between them. During vehicle operation, it can effectively prevent rainwater, road mud and sand, and dust in the air from entering the inside of the base 1 through the gap, thereby preventing transmission jamming or accelerated component wear, creating a clean and stable working environment for the internal transmission mechanism; it can also reduce external noise entering the vehicle through the gap, improving the quietness of the vehicle ride. In addition, during the repeated driving of the handle 2 to open the door, the base 1 will vibrate slightly due to the force, and the elasticity of the sealing strip 4 can buffer the vibration impact between the base 1 and the door, reducing abnormal noises caused by rigid collisions. At the same time, through continuous sealing, it can delay the corrosion and aging of the connection between the base 1 and the door, further extending the service life of the entire handle assembly.

[0055] Optionally, the sealing strip 4 is a flexible component, such as a rubber component. The sealing strip 4 can be a ring structure with its ends connected, or it can be a strip structure that extends circumferentially along the base 1 and then joins its ends together.

[0056] Please see Figure 1 and Figure 3 In some embodiments, the hinge portion 202 has a plurality of sequentially distributed reinforcing ribs 2021, and adjacent reinforcing ribs 2021 are spaced apart.

[0057] When the user applies force to the drive unit 201 of the handle 2, causing the hinge unit 202 to rotate around the hinge point with the base 1, and driving the rocker arm 3 to move via the rolling part 203, the hinge unit 202 needs to withstand the tension from the drive unit 201, the reaction force transmitted by the rolling part 203, and the impact load from vehicle bumps. Multiple sequentially distributed reinforcing ribs 2021 increase the strength of the hinge unit 202 and can distribute these forces, improving the overall structural rigidity and deformation resistance of the hinge unit 202. This prevents fatigue damage such as bending and breakage of the hinge unit 202 due to long-term stress, ensuring stable and reliable power transmission. Simultaneously, the spacing design between adjacent reinforcing ribs 2021 enhances strength while avoiding excessive weight increase in the hinge unit 202, achieving structural lightweighting and reducing inertial resistance during handle 2 operation, making operation more effortless.

[0058] Please see Figure 1 and Figure 3 In some embodiments, the inner plate of the base 1 is provided with a connecting post 102, the connecting post 102 is provided with a connecting hole 1021, the connecting hole 1021 is used to connect with the vehicle body, and the outer peripheral surface of the connecting post 102 is provided with a plurality of radially distributed reinforcing plates 103.

[0059] The connecting holes 1021 on the connecting post 102 enable precise assembly and fixation of the base 1 to the vehicle body. The radially distributed reinforcing plates 103 tightly connect the connecting post 102 to the inner plate of the base 1, increasing the contact area between them. This prevents breakage or loosening due to concentrated stress when the connecting post 102 is connected to the base 1 via a single root, ensuring long-term stability of the connection between the base 1 and the vehicle body and preventing the base 1 from wobbling or shifting during vehicle travel. When force is applied to the handle 2, the hinge 202 drives the rolling part 203 to rotate the rocker arm 3. The tension and reaction forces generated during the transmission process are transmitted to the connecting post 102 through the base 1. The radially distributed reinforcing plates 103 evenly distribute these forces across various areas of the inner plate of the base 1, rather than concentrating them at the root of the connecting post 102. This effectively reduces local stress load and further enhances the fatigue strength of the connecting post 102, preventing deformation or damage due to long-term stress. Furthermore, the radial design of the reinforcing plate 103 not only enhances structural strength but also improves the overall rigidity of the base 1, reducing slight deformation of the base 1 under stress. This ensures that the fitting accuracy of transmission components such as the rocker arm 3 and the hinge 202 remains unaffected, guaranteeing smooth door opening operation at all times. With long-term use, this structure significantly slows down the aging and wear of the connecting column 102 and the base 1, extending the service life of the entire handle assembly.

[0060] Optionally, the connecting hole 1021 corresponds to the connecting position on the vehicle body to achieve connection with the vehicle body. For example, the vehicle body has mounting holes that form connecting positions, and bolts are inserted into the mounting holes and connecting holes 1021 to achieve a fixed connection. Alternatively, snap-fit ​​parts can be provided on the vehicle body, forming connecting positions, and inserted into the connecting holes 1021 to fix the base 1.

[0061] Based on the same inventive concept, this application also provides a vehicle. The vehicle includes the aforementioned passenger compartment handle assembly.

[0062] The vehicle provided by this utility model adopts the aforementioned handle assembly. When the user applies force to the drive part 201 of the handle 2, the hinge part 202 rotates around its own axis, causing the spherical or hemispherical rolling part 203 on it to contact the transmission part of the opening rocker arm 3 and apply force. At this time, the rolling part 203 rotates around its own center, so that rolling friction is formed between the two rather than traditional sliding friction. Since the hinge part 202 is inserted into the mounting through hole and the drive part 201 is located on the outside of the base 1, the drive part 201 and the hinge part 202 can jointly seal the mounting through hole, improving the sealing performance of the base 1. Even if the vehicle is driving on a bumpy road, the probability of dust and impurities entering can be reduced. In addition, the friction force of rolling friction itself is much smaller than that of sliding friction. Even if some dust and impurities enter, the wear on the transmission part and the hinge part 202 can be greatly reduced, avoiding the high-frequency abnormal noise problem caused by insufficient lubrication and impurity intrusion in the traditional structure. Furthermore, the rolling part 203 forms point contact with the transmission part, reducing rigid frictional loss between the handle 2 and the base 1 and the opening rocker arm 3, effectively delaying the fatigue failure rate of the hinge part 202, and significantly extending the service life of the entire handle assembly. By optimizing the transmission friction form, this application not only improves the smoothness of the user's operation when opening the car door, but also eliminates frictional noises during long-term use, improving the comfort and perceived quality of vehicle use, while reducing the need and cost of later maintenance due to component wear.

[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.
