Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile, especially relate to a vehicle-mounted article lifting mechanism, a vehicle door assembly and a vehicle. BACKGROUND

[0002] As a widely used means of transportation, the function and purpose of the automobile are constantly enriched and expanded. In recent years, with the upgrading of in-vehicle facilities such as car entertainment systems, the phenomenon of installing various articles in the car has gradually become popular. For example, in order to enrich the experience during driving and riding, the car may be equipped with a microphone for passengers to sing karaoke, or it may place umbrellas, water bottles and other articles. The provision of these articles enhances the added value of the car.

[0003] In the design of the storage of the vehicle-mounted article, it is necessary to take out conveniently when using and to store properly when not using to avoid occupying the space in the car. Therefore, the storage method of the article becomes one of the key points of the design. In order to realize this function, the design of the article lifting structure appears in the prior art. This structure allows the article to be raised when needed for the passenger to use, and to be lowered and hidden in the car when not in use, thereby balancing the convenience of use and the efficiency of space utilization.

[0004] However, the article lifting structure in the prior art adopts the mode of driving the rotation of the connecting rod by the motor, and realizes the lifting of the article by directly driving the guide rail to slide up and down through the connecting rod. Although this design can realize the lifting action, it has obvious defects: the connecting rod needs a large rotation amplitude to ensure that the guide rail has sufficient lifting stroke, and the rotation of the connecting rod needs to occupy a large space. This large space occupation limits the installation and layout of the article lifting structure in the limited space, especially in the limited space environment of the car interior, its installation and use are greatly limited. SUMMARY

[0081] The terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include one or more of the features.

[0082] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0083] In this application, the vehicle includes a vehicle body, a power assembly, and a vehicle information and entertainment system, etc. The vehicle information and entertainment system, as an important module to improve the driving and riding experience, integrates multimedia playback, navigation, communication, and intelligent interconnection and other functions. With the increasing demand for in-vehicle entertainment, the karaoke function has gradually become an important part of the vehicle entertainment system, and the microphone is equipped in the vehicle, which has become a kind of vehicle goods. The vehicle goods also include a water cup, an umbrella and other goods that are convenient to use in the vehicle, to meet the diversified needs of users during driving and riding.

[0084] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0085] With reference to all the drawings, in one illustrative embodiment of the vehicle-mounted article lifting mechanism of the present application, the vehicle-mounted article lifting mechanism comprises a housing 1, which serves as the mounting base of the mechanism. The vehicle body of the vehicle has a vehicle cabin, and the housing 1 can be arranged in the vehicle cabin.

[0086] With reference to Figures 3 to 5 In some embodiments, the vehicle-mounted article lifting mechanism further comprises a linkage rod 2, which is rotatably connected to the housing 1 at the middle part, so that the linkage rod 2 and the housing 1 form a lever mechanism, wherein the connecting point on the housing 1 serves as the fulcrum, and the two ends of the linkage rod 2 serve as the power end and the resistance end, respectively. A fulcrum shaft 101 is arranged on the housing 1, and the fulcrum shaft 101 penetrates the shaft hole of the linkage rod 2 to achieve the rotatable connection of the linkage rod 2.

[0087] With reference to Figures 2 to 5 And Figure 7 In some embodiments, the vehicle-mounted article lifting mechanism further comprises a first lifting seat 3, which is connected to the housing 1 and can slide up and down in the vertical direction on the housing 1. One end of the linkage rod 2 is movably connected to the first lifting seat 3. This connection allows the first lifting seat 3 to be lifted in the vertical direction under the driving of the linkage rod 2. Specifically, the first lifting seat 3 can be connected to the housing 1 through a slide rail, a slide groove or other guiding mechanism to ensure its smooth movement in the vertical direction. Since the linkage rod 2 is movably connected to the first lifting seat 3, when the linkage rod 2 rotates around the rotation center at the middle part, the lifting movement of one end of the linkage rod 2 will be transmitted to the first lifting seat 3 through the movable connection, thereby driving the first lifting seat 3 to slide up and down in the vertical direction. The rotation of the linkage rod 2 and the up-and-down sliding of the first lifting seat 3 will not interfere with each other.

[0088] With reference to Figures 3 to 5 In some embodiments, the vehicle-mounted article lifting mechanism further comprises a driving assembly 5, which is arranged on the housing 1, and one end of the linkage rod 2, which is away from the first lifting seat 3, is movably connected to the driving assembly 5. The driving assembly 5 is the power source of the entire vehicle-mounted article lifting mechanism, and its function is to drive the lifting of one end of the linkage rod 2 through the movable connection of the linkage rod 2, to drive the lifting of the first lifting seat 3 connected to the other end of the linkage rod 2 through the transmission of the linkage rod 2, and to realize the lifting of the vehicle-mounted article connected to the first lifting seat 3. The driving assembly 5 can be implemented in various ways, such as motor drive, hydraulic drive or pneumatic drive, etc.

[0089] With reference to Figures 4 to 5, further, the driving assembly 5 drives the linkage rod 2 to lift away from one end of the first lifting seat 3, so that when the driving assembly 5 drives the linkage rod 2 to lift away from one end of the first lifting seat 3, the linkage rod 2 rotates and drives the first lifting seat 3 at the other end and other structures connected with the first lifting seat 3 to descend; when the driving assembly 5 drives the linkage rod 2 to descend away from one end of the first lifting seat 3, the linkage rod 2 rotates and drives the first lifting seat 3 at the other end and other structures connected with the first lifting seat 3 to ascend. The first lifting seat 3 is used to lift or lower the vehicle-mounted articles, and the vehicle-mounted articles are other structures connected with the first lifting seat 3. The lifting action is realized based on the lever principle, and the lifting of the other end is realized by the driving control of one end of the linkage rod 2 by the driving assembly 5. Specifically, when the driving assembly 5 pushes one end of the linkage rod 2 to ascend, the linkage rod 2 rotates around the rotation center in the middle, and the other end thereof descends, thereby driving the first lifting seat 3 and the vehicle-mounted articles connected with the first lifting seat 3 to descend; conversely, when the driving assembly 5 pulls one end of the linkage rod 2 to descend, the other end of the linkage rod 2 ascends, thereby driving the first lifting seat 3 and the vehicle-mounted articles connected with the first lifting seat 3 to ascend. The structure design reduces the rotation radius of the linkage rod 2, and in the case of realizing the same lifting stroke, the linkage rod 2 occupies less moving space in the horizontal direction, thereby reducing the space required for the movement of the linkage rod 2 and reducing the structure volume of the vehicle-mounted article lifting mechanism. In addition, the linkage rod 2 sets the rotation center in the middle, the power arm and the resistance arm are relatively small, the linkage rod 2 is not easy to deform, the force transmission loss is small, the driving force received by the first lifting seat is ensured, and the vehicle-mounted articles can be quickly lifted.

[0090] Referring to Figures 1 to 5 In some embodiments, the vehicle-mounted article lifting mechanism further comprises a support 4 connected with the first lifting seat 3, and the support 4 is provided with a containing cavity for placing the vehicle-mounted articles. The containing cavity in the support 4 is designed to accommodate and firmly fix the vehicle-mounted articles, so as to ensure that the vehicle-mounted articles remain stable during lifting and do not fall off due to bumps during driving. The support 4 can be connected with the first lifting seat 3 by screw connection, buckle or other fixing methods, so that the vehicle-mounted articles placed in the support 4 can move synchronously with the first lifting seat 3. In use, the vehicle-mounted articles are placed or fixed in the containing cavity of the support 4, and the first lifting seat 3 drives the support 4 to move up and down along the vertical direction, thereby realizing the lifting of the vehicle-mounted articles.

[0091] Referring to Figure 1 , Figures 3 to 5 and Figure 8In some embodiments, the vehicle-mounted article lifting mechanism further comprises a second lifting seat 6. The introduction of the second lifting seat 6 provides better mechanical balance and motion control performance for the entire vehicle-mounted article lifting mechanism.

[0092] Further, the second lifting seat 6 is movably connected to the end of the linkage rod 2 away from the first lifting seat 3 and is slidably connected to the housing 1 in the vertical direction. This design enables the second lifting seat 6 to realize vertical lifting motion. Similar to the first lifting seat 3, the second lifting seat 6 can be connected to the housing 1 through a slide rail, a slide groove or other guiding mechanisms to ensure smooth movement in the vertical direction. By arranging the first lifting seat 3 and the second lifting seat 6 at both ends of the linkage rod 2, symmetrical force bearing of the double lifting seats is realized, i.e. the gravity of the lifting seats is borne by both ends of the linkage rod 2, avoiding the problem of linkage rod 2 unbalanced loading caused by unilateral force, thereby prolonging the service life of the entire mechanism.

[0093] Further, the driving assembly 5 is movably connected to the second lifting seat 6 to drive the lifting of the second lifting seat 6. The driving assembly 5 drives the lifting of the second lifting seat 6, which in turn drives the lifting of the first lifting seat 3 through the linkage rod 2. The driving assembly 5 can be realized by motor, hydraulic or pneumatic, etc., and is connected to the second lifting seat 6 through a transmission mechanism (such as gear, belt or screw), which can accurately control the lifting action of the second lifting seat 6.

[0094] When the end of the linkage rod 2 movably connected to the second lifting seat 6 rotates, displacement occurs in both the vertical and horizontal directions, so that the end of the linkage rod 2 is subjected to vertical reaction force and horizontal reaction force on the second lifting seat 6. Since the second lifting seat 6 is constrained to slide in the vertical direction and is supported by the housing 1 in the horizontal direction, the horizontal reaction force of the linkage rod 2 acts on the second lifting seat 6, and the housing 1 supports the second lifting seat 6 to offset the horizontal reaction force of the linkage rod 2. Further, the driving assembly 5 generates vertical force to drive the lifting of the second lifting seat 6. The structure of the driving assembly 5 is generally arranged vertically. Since the horizontal reaction force of the linkage rod 2 is offset by the support of the housing 1, the horizontal reaction force of the linkage rod 2 is prevented from being transmitted to the driving assembly 5, which avoids the bending deformation of the driving assembly 5 and prevents the lifting driving force acting on the second lifting seat 6 from being inclined relative to the vertical direction, thereby ensuring that the driving force generated by the driving assembly 5 is all vertically applied to the second lifting seat 6, ensuring smooth and rapid lifting of the second lifting seat 6.

[0095] Reference Figures 3 to 5In some embodiments, the driving assembly 5 comprises a rotary motor 501. The rotary motor 501 serves as the power source of the entire vehicle-mounted article lifting mechanism, and its role is to provide stable rotary power. The rotary motor 501 can be selected according to actual needs to select a model with appropriate power and speed to meet the movement requirements of the vehicle-mounted article lifting mechanism.

[0096] With reference to Figures 3 to 5 In some embodiments, the driving assembly 5 further comprises a screw rod 502. The screw rod 502 is connected with the rotary motor 501 and is driven to rotate by the rotary motor 501. The screw rod 502 is connected with the output shaft of the rotary motor 501 through a shaft coupling or other connection means to ensure efficient power transmission.

[0097] The screw rod 502 is threadedly connected with the second lifting seat 6. The second lifting seat 6 is provided with a threaded hole matched with the screw rod 502, and the rotation of the screw rod 502 is converted into the linear motion of the lifting seat through the threaded connection. Through the forward and reverse rotation control of the rotary motor 501, the forward and reverse rotation of the screw rod 502 can be realized, thereby driving the upward and downward movement of the second lifting seat 6, and further driving the upward and downward movement of the first lifting seat 3 through the linkage rod 2.

[0098] The threaded connection design not only improves the control accuracy of the lifting mechanism, but also maintains the second lifting seat 6 fixed in the vertical direction in the non-working state through the self-locking property of the threaded pair, and further supports the first lifting seat 3 in the vertical direction through the linkage rod 2, so that the vehicle-mounted article is kept stable on the first lifting seat 3, avoiding the accidental falling of the vehicle-mounted article and improving the safety. In order to avoid the screw rod 502 from rotating out of the threaded hole of the second lifting seat 6, a limiting nut 503 is fixedly installed at the end of the screw rod 502 away from the rotary motor 501.

[0099] With reference to Figures 4 to 5 In some embodiments, the linkage rod 2 is provided with a first sliding groove 201 and a second sliding groove 202 at both ends, respectively. The first sliding groove 201 and the second sliding groove 202 both penetrate the linkage rod 2 along a direction parallel to the rotation axis of the linkage rod 2. The first sliding groove 201 and the second sliding groove 202 have a certain length in the length direction of the linkage rod 2, which provides a movement space for the connecting structure of the first lifting seat 3 and the second lifting seat 6, and realizes the movable connection of the linkage rod 2 with the first lifting seat 3 and the second lifting seat 6.

[0100] Further, the first lifting seat 3 is provided with a first sliding rod 301, which is rotatable and slidable in the first sliding groove 201. The first sliding rod 301 can rotate in the first sliding groove 201, so that the linkage rod 2 can rotate relative to the first lifting seat 3 with the first sliding rod 301 as the axis. When the linkage rod 2 rotates, the first lifting seat 3 slides up and down, and the linkage rod 2 rotates relative to the first lifting seat 3 with the first sliding rod 301 as the axis. This structural design realizes the movable connection of the linkage rod 2 and the first lifting seat 3, so that when the linkage rod 2 rotates, the first sliding rod 301 slides in the first sliding groove 201, ensuring that the first sliding rod 301 drives the first lifting seat 3 to lift and lower, and the rotation of the linkage rod 2 and the lifting and lowering of the first lifting seat 3 do not interfere with each other, and the transmission is smooth.

[0101] Further, the second lifting seat 6 is provided with a second sliding rod 601, which is rotatable and slidable in the second sliding groove 202. Similar to the first lifting seat 3, the second sliding rod 601 can rotate in the second sliding groove 202, so that the linkage rod 2 can rotate relative to the second lifting seat 6 with the first sliding rod 301 as the axis. When the linkage rod 2 rotates, the second lifting seat 6 slides up and down, and the linkage rod 2 rotates relative to the second lifting seat 6 with the second sliding rod 601 as the axis. This structural design realizes the movable connection of the linkage rod 2 and the second lifting seat 6, so that the lifting and lowering of the second lifting seat 6 can drive the linkage rod 2 to rotate by sliding the second sliding rod 601 in the second sliding groove 202, and the rotation of the linkage rod 2 and the lifting and lowering of the first lifting seat 3 do not interfere with each other, and the transmission is smooth.

[0102] Further, the first sliding groove 201 and / or the second sliding groove 202 extends along the length direction of the linkage rod 2 to the end face of the linkage rod 2 in a direction away from the rotation center of the linkage rod 2, so that one end of the first sliding groove 201 and / or the second sliding groove 202 is open. This structural design not only reduces the material and weight of the linkage rod 2, but also reduces the cost, and makes the machining of the first sliding groove 201 and / or the second sliding groove 202 easier, and the first sliding rod 301 and / or the first sliding rod 301 can be assembled into the sliding groove from multiple directions, improving the assembly convenience.

[0103] In another embodiment, the first lifting seat 3 is connected to the linkage rod 2 through a first movable connecting rod, and the second lifting seat 6 is connected to the linkage rod 2 through a second movable connecting rod. The two ends of the first movable connecting rod are respectively connected to the first lifting seat 3 and the linkage rod 2, and the two ends of the second movable connecting rod are respectively connected to the second lifting seat 6 and the linkage rod 2. Both ends of the first movable connecting rod and both ends of the second movable connecting rod are connected in a hinged manner. This structure provides a movable connection between the lifting seat and the linkage rod 2 through a connecting rod transmission, so that when the lifting seat slides up and down, the linkage rod 2 is pushed and pulled through the movable connecting rod, thereby driving the lifting seat to drive the linkage rod 2. The rotating linkage rod 2 drives the lifting seat to slide up and down in the opposite direction in the same way, and the two ends of the movable connecting rod are hinged to link them to move and rotate together, avoiding interference between the rotation of the linkage rod 2 and the lifting of the lifting seat.

[0104] Referring to Figures 1 to 2 and Figure 9 In some embodiments, the housing 1 is provided with a first guide hole 102 and a second guide hole 103, both of which are vertically arranged. The first sliding rod 301 is slidingly connected in the first guide hole 102, and the second sliding rod 601 is slidingly connected in the second guide hole 103. When the first lifting seat 3 slides up and down, the first sliding rod 301 slides up and down in the first guide hole 102. When the second lifting seat 6 slides up and down, the second sliding rod 601 slides up and down in the second guide hole 103. This structure provides a precise vertical guide path for the first sliding rod 301 and the second sliding rod 601, thereby providing a precise vertical guide path for the first lifting seat 3 and the second lifting seat 6, ensuring that the sliding rod and the lifting seat move in the predetermined vertical direction during lifting. The vertically arranged guide holes can effectively limit the movement of the sliding rod and the lifting seat in the horizontal direction, avoiding the deviation of the sliding rod caused by the horizontal force generated when the linkage rod 2 rotates, thereby ensuring the linear lifting motion of the lifting seat. Since the lifting seat slides up and down vertically through the sliding rail, the guide hole cooperates with the sliding rod to limit the freedom of movement of the lifting seat in the horizontal direction, avoiding the generation of lateral force (horizontal force) on the sliding rail, reducing the wear of the sliding rail and improving the service life.

[0105] Referring to Figure 2 , Figure 4 and Figure 5 In some embodiments, the housing 1 is provided with a first mounting cavity 104 and a second mounting cavity 105, which are vertically arranged and have a top through the housing 1. This structure provides a mounting space 400 inside the housing 1, thereby achieving embedded installation and reducing the size of the structure.

[0106] Further, the first lifting seat 3 slides in the first installation cavity 104, and the second lifting seat 6 slides in the second installation cavity 105. By embedding the lifting seat in the installation cavity, the installation cavity guides and limits the lifting seat, and the movement of the lifting seat is strictly limited in the vertical direction, avoiding the lifting seat from deviating or shaking in the horizontal direction. The structure design embeds the first lifting seat 3 and the second lifting seat 6 in independent installation cavities, making the movement of the lifting seat in the vertical direction more stable. In addition, the cavity structure also provides rigid support, enhancing the mechanical strength of the lifting seat, so that it can resist external impact. Through the protection of the installation cavity, the intrusion of dust, liquid and other external impurities is isolated, ensuring that the lifting seat can operate stably in a complex vehicle environment.

[0107] Referring to Figures 3 to 6 In some embodiments, the shell 1 includes a skeleton 106. The skeleton 106 is provided with a first installation slot 1061 and a second installation slot 1062, both of which pass through the skeleton 106 from top to bottom. The skeleton 106 serves as a basic support structure and mainly plays a role in bearing and fixing various components. The first installation slot 1061 and the second installation slot 1062 provide installation space 400 for embedded installation of components.

[0108] Referring to Figure 3 And Figure 9 In some embodiments, the shell 1 further includes an outer shell 107, which is mounted on the skeleton 106. The outer shell 107 includes a first outer shell 1071 and a second outer shell 1072. The first outer shell 1071 and the second outer shell 1072 are respectively mounted on both sides of the skeleton 106. By fixing the first outer shell 1071 and the second outer shell 1072 on the skeleton 106, a complete shell 1 structure is formed. This split type outer shell 107 design not only facilitates assembly, but also allows individual disassembly and replacement of damaged components when needed, without the need to replace the entire shell 1.

[0109] Further, the first outer shell 1071 and the second outer shell 1072 respectively close both sides of the first installation slot 1061 to form the first installation cavity 104; and the first outer shell 1071 and the second outer shell 1072 respectively close both sides of the second installation slot 1062 to form the second installation cavity 105. Through this split type assembly method, the first installation cavity 104 and the second installation cavity 105 are accurately constructed at the corresponding positions of the skeleton 106, and the outer shell 107 can be removed to laterally open the installation slot, facilitating the installation and removal of the lifting seat.

[0110] In some embodiments, the linkage rod 2 is installed on the fulcrum shaft 101, and the fulcrum shaft 101 passes through the shaft hole of the linkage rod 2. The shell 107 is connected to the skeleton 106 laterally, so that the shell 107 is attached to the end of the fulcrum shaft 101 away from the skeleton 106, blocking the linkage rod 2 from being axially removed from the fulcrum shaft 101. As a cover of the shell 1, it can also limit the installation of the linkage rod 2 as a limiting structure. This structure design makes it easy to disassemble and install the linkage rod 2 laterally, improving the convenience of assembly and maintenance.

[0111] Further, the skeleton 106 is provided with a first installation slot 1061 and a second installation slot 1062, both of which pass through the top of the skeleton 106. The first installation slot 1061 and the second installation slot 1062 divide the skeleton 106 into three structural columns 1063, making the skeleton 106 in the shape of a mountain. This structure design enables the skeleton 106 to be manufactured by one-piece molding, reducing manufacturing costs.

[0112] The skeleton 106 is vertically provided with the first guide rail 1064 and the second guide rail 1065. The first lifting seat 3 and the second lifting seat 6 are respectively installed on the first guide rail 1064 and the second guide rail 1065. The first lifting seat 3 slides along the first guide rail 1064, and the second lifting seat 6 slides along the second guide rail 1065, achieving the vertical movement of the first lifting seat 3 and the second lifting seat 6. The cross section of the first guide rail 1064 and the second guide rail 1065 is T-shaped, and the first guide rail 1064 and the second guide rail 1065 are integrally arranged on the corresponding structural column 1063. The first lifting seat 3 and the second lifting seat 6 are both T-shaped sliding grooves 7, which cooperate with the guide rails to achieve the sliding of the lifting seats on the guide rails and embed the guide rails in the lifting seats. This structure design enables the guide rails to be processed integrally with the skeleton 106, reducing manufacturing costs. In addition, the guide rails are embedded in the lifting seats, and the two partially overlap in the horizontal direction, reducing the space occupation of the vehicle-mounted article lifting mechanism in the horizontal direction. The installation slot passes through the top of the skeleton 106. With the assembly of the T-shaped guide rail and the sliding groove 7, the lifting seat can be installed in the installation slot from top to bottom, and it can be assembled stably without lateral restriction of the shell 107, improving the convenience of assembly operation.

[0113] In some embodiments, the driving assembly 5 includes a linear motor. The linear motor is an electromagnetic device that directly converts electrical energy into linear motion mechanical energy, without the need for intermediate transmission mechanisms to achieve linear motion of objects, with the characteristics of high precision, high response speed and simple structure. The use of linear motors eliminates the complex structure of traditional mechanical transmission (such as screw, gear, etc.), reduces the mechanical transmission delay, and thus improves the lifting speed and response ability.

[0114] In some embodiments, the driving assembly 5 further comprises a lifting rod. The lifting rod is connected with the linear motor and is driven to lift by the motor. The lifting rod is provided with a lifting slide rod, and the linkage rod 2 is provided with a linkage sliding groove at an end away from the first lifting seat 3. The lifting slide rod is rotatably and slidably arranged in the linkage sliding groove. Similar to the movable connection between the lifting seat and the linkage rod 2, this design enables the linear motion of the lifting rod to be transmitted to the linkage rod 2 through the lifting slide rod, thereby driving the linkage rod 2 to rotate around its rotation center, and realizing the lifting of the first lifting seat 3. Through the cooperation of the lifting slide rod and the linkage sliding groove, efficient force transmission is ensured, and at the same time, a certain degree of rotational freedom is allowed to adapt to the rotational motion of the linkage rod 2.

[0115] Referring to Figures 4 to 5 In some embodiments, the end of the linkage rod 2 away from the first lifting seat 3 is located above the driving assembly 5. This structure design enables the driving assembly 5 and the end of the linkage rod 2 to be arranged in a stacked manner in the vertical direction, thereby reducing the space occupation in the horizontal direction and reducing the horizontal size of the vehicle-mounted article lifting mechanism.

[0116] Further, the distance from the end of the linkage rod 2 close to the first lifting seat 3 to the rotation center of the linkage rod 2 is a first distance, and the distance from the other end of the linkage rod 2 to the rotation center is a second distance. The first distance is greater than the second distance. Through this design, the end of the linkage rod 2 close to the first lifting seat 3 is the vehicle-mounted article end, and the other end of the linkage rod 2 is the driving end. The force arm of the vehicle-mounted article end is lengthened, and the force arm of the driving end is shortened. According to the principle of lever, the difference in the length of the force arm can realize the amplification of the lifting stroke. Under the small displacement of the driving assembly 5, the vehicle-mounted article end can obtain sufficient lifting stroke, i.e., the first lifting seat 3 has sufficient lifting stroke, thereby meeting the requirements of the lifting function in the vehicle-mounted scenario. The driving assembly 5 and the end of the linkage rod 2 can be arranged in a stacked manner in the vertical direction in a limited vertical space, thereby ensuring the small size of the lifting mechanism.

[0117] Further, when the vehicle-mounted article lifting mechanism includes a second lifting seat 6, the second lifting seat 6 is movably connected to the linkage rod 2 at an end away from the first lifting seat 3, and the second lifting seat 6 is slidably connected to the housing 1 in the vertical direction. The driving assembly 5 is movably connected to the second lifting seat 6 to drive the second lifting seat 6 to lift. At this time, the second lifting seat 6 is above the driving assembly 5, and the driving assembly 5 and the second lifting seat 6 are arranged in a stack from top to bottom, so that the driving assembly 5 occupies the space below the second lifting seat 6 inside the housing 1, and the vertical movement stroke of the second lifting seat 6 is smaller than that of the first lifting seat 3. The structure design of the linkage rod 2 lengthens the force arm at the vehicle-mounted article end and shortens the force arm at the driving end, so that the second lifting seat 6 with a shorter stroke can drive the first lifting seat 3 to lift with a relatively longer stroke through the linkage rod 2. The first lifting seat 3, the second lifting seat 6, and the driving assembly 5 fully use the vertical space of the housing 1, and improve the compactness of the vehicle-mounted article lifting mechanism, which is convenient for installation and layout in the limited space in the vehicle.

[0118] Referring to Figures 2 to 5 In some embodiments, the vehicle-mounted article lifting mechanism further includes an elastic member 8. The elastic member 8 is arranged in the housing 1 and connected to the first lifting seat 3. The arrangement of the elastic member 8 provides a buffering mechanism for the lifting mechanism, which can absorb the kinetic energy of the first lifting seat 3 when it is lowered, so as to avoid damage caused by hard collision. The elastic member 8 can be a spring, elastic rubber, or other elastic material, one end of which is fixed inside the housing 1, and the other end of which is connected to the first lifting seat 3.

[0119] Further, when the first lifting seat 3 is lowered, the elastic member 8 at least partially bears the weight of the first lifting seat 3 and other structures connected to the first lifting seat 3. When the elastic member 8 is an elastic compression member, the first lifting seat 3 will compress the elastic member 8 when it is lowered, and the elastic member 8 can generate elastic force during the compression process. When the elastic member 8 is an elastic stretching member, the first lifting seat 3 will stretch the elastic member 8 when it is lowered, and the elastic member 8 can generate elastic force during the stretching process. When the first lifting seat 3 is lowered to the lowest point of its lifting stroke, the elastic force can balance or even be greater than the gravity of the first lifting seat 3 and the vehicle-mounted articles connected to the first lifting seat 3. This design makes it easier for the first lifting seat 3 to be lifted by the driving assembly 5 when it needs to be lifted, so that the vehicle-mounted articles can reach the use position more quickly, and the response speed and user experience of the system are improved.

[0120] In addition, referring to all the drawings, the application also provides a vehicle-mounted article lifting mechanism, which includes a housing 1 as the installation basis of the mechanism. The vehicle body has a vehicle cabin, and the housing 1 can be arranged in the vehicle cabin.

[0121] In some embodiments, the vehicle-mounted article lifting mechanism further comprises a linkage rod 2, one end of which is rotatably connected to the housing 1, so that the linkage rod 2 and the housing 1 form a lever mechanism, with the connecting point on the housing 1 as the fulcrum. A fulcrum rotating shaft 101 is arranged on the housing 1, which penetrates the shaft hole of the linkage rod 2 to realize the rotatable connection of the linkage rod 2.

[0122] In some embodiments, the vehicle-mounted article lifting mechanism further comprises a first lifting seat 3, which is connected to the housing 1 and can slide up and down in the vertical direction on the housing 1. The linkage rod 2 is movably connected to the first lifting seat 3 at the end away from its rotating center. This connection allows the first lifting seat 3 to be lifted vertically by the linkage rod 2. Specifically, the first lifting seat 3 can be connected to the housing 1 through sliding rails, sliding grooves or other guiding mechanisms to ensure its smooth movement in the vertical direction. Since the linkage rod 2 is movably connected to the first lifting seat 3, when the linkage rod 2 rotates around its rotating center, the lifting movement of its one end will be transmitted to the first lifting seat 3 through the movable connection, thereby driving the first lifting seat 3 to slide up and down in the vertical direction. The rotation of the linkage rod 2 and the up-and-down movement of the first lifting seat 3 do not interfere with each other.

[0123] In some embodiments, the vehicle-mounted article lifting mechanism further comprises a driving assembly 5, which is arranged on the housing 1 and movably connected to the linkage rod 2. The driving assembly 5 is the power source of the entire vehicle-mounted article lifting mechanism. Its function is to drive the linkage rod 2 to rotate and lift by movably connecting the linkage rod 2, and to drive the first lifting seat 3 connected to the end of the linkage rod 2 to lift through the transmission of the linkage rod 2, thereby realizing the lifting of the vehicle-mounted articles connected to the first lifting seat 3. The driving assembly 5 can be realized in various ways, such as motor drive, hydraulic drive or pneumatic drive, etc.

[0124] In some embodiments, the driving assembly 5 drives the linkage rod 2 to lift, so that when the driving assembly 5 drives the linkage rod 2 to lift, the linkage rod 2 rotates and drives the first lifting seat 3 at one end and other structures connected with the first lifting seat 3 to lift; when the driving assembly 5 drives the linkage rod 2 to lower, the linkage rod 2 rotates and drives the first lifting seat 3 at one end and other structures connected with the first lifting seat 3 to lower. Due to the rotation connection of one end of the linkage rod 2 and the connection of the other end of the linkage rod 2 with the first lifting seat 3, the driving assembly 5 is connected in the middle of the linkage rod 2, and a proportional relationship is formed between the power arm and the resistance arm, so that the lifting stroke is amplified. One end of the linkage rod 2 connected with the first lifting seat 3 is the vehicle-mounted article end, and the other end of the linkage rod 2 is the driving end. Under the displacement of the driving assembly 5, the vehicle-mounted article end can obtain sufficient lifting stroke, which meets the demand for lifting function in the vehicle-mounted scene. In addition, the connection mode of the driving assembly 5 and the linkage rod 2 enables the driving assembly 5 and the linkage rod 2 to overlap to a certain extent in the horizontal direction. This design reduces the size of the vehicle-mounted article lifting mechanism in the horizontal direction, significantly reduces the volume of the entire mechanism, and makes it more suitable for installation and use in the limited space of the vehicle-mounted environment.

[0125] Referring to Figures 10 to 13 In addition, the present application also provides a vehicle door assembly, which comprises an outer panel 200. The outer panel 200 is an external cover of the vehicle door, usually made of metal (such as steel or aluminum) or composite material, with high strength and corrosion resistance. The outer panel 200 not only plays a role in protecting the internal structure of the vehicle door, but also bears an important function of vehicle appearance design, directly affecting the appearance and aerodynamic performance of the vehicle.

[0126] Referring to Figures 10 to 13 In some embodiments, the vehicle door assembly further comprises an inner panel 300. The inner panel 300 is an internal structural component of the vehicle door, usually made of metal material (such as high-strength steel), mainly playing a supporting and protecting role. It forms a complete frame of the vehicle door together with the outer panel 200, and forms a closed installation space 400 between the two, which is used to accommodate various functional components of the vehicle door, such as the glass lifter, the door lock mechanism, the sound insulation material, and the vehicle-mounted article lifting mechanism in the present application. The outer panel 200 is fixed with the inner panel 300 by welding, riveting or other connection methods, to form the main structure of the vehicle door together.

[0127] The vehicle-mounted article lifting mechanism 500 as described above is arranged in the installation space 400. By installing the vehicle-mounted article lifting mechanism 500 in the installation space 400 between the inner panel 300 and the outer panel 200, the integrated installation of the internal cavity of the vehicle door is realized. This design makes full use of the idle space inside the vehicle door, avoids occupying additional passenger compartment space, and thus improves the utilization efficiency of the internal space of the vehicle.

[0128] Referring to Figures 10 to 13 In some embodiments, the outer plate 200 includes a window frame portion 2001 and a door body portion 2002, and the inner plate 300 is connected to the door body portion 2002. The window frame portion 2001 of the outer plate 200 provides mounting and support functions for the vehicle door glass, and also constitutes the upper boundary of the vehicle door. The inner plate 300 is connected to the door body portion 2002, and together with the outer plate 200 forms the main structure of the vehicle door, and forms a closed mounting space 400 between them. This design not only ensures the structural strength of the vehicle door, but also provides a spatial basis for the integration of the vehicle-mounted object lifting mechanism.

[0129] Referring to Figures 10 to 13 In some embodiments, the inner plate 300 is provided with an opening 3001, and the first lifting seat 3 of the vehicle-mounted object lifting mechanism 500 can pass through the opening 3001 to lift and extend the other structure connected by the first lifting seat 3 to the window frame portion 2001 or lower and retract into the mounting space 400. Figures 10 to 12 When the first lifting seat 3 extends or retracts the microphone 100, the microphone 100 is the other structure connected by the first lifting seat 3.

[0130] By providing the opening 3001 on the inner plate 300, the vehicle-mounted object can be lifted and extended to the window frame portion 2001 when needed, facilitating the passenger to take and use; when not in use, the vehicle-mounted object can be lowered and stored in the mounting space 400, avoiding occupying the space inside the vehicle. This design makes the extension and retraction process of the vehicle-mounted object more smooth, and will not be hindered by the passengers inside the vehicle.

[0131] In addition, the application also provides a vehicle, which includes a vehicle body. The vehicle body is the core structure of the vehicle, including a chassis and a vehicle body cover. The chassis provides the basic support and driving function of the vehicle, and the vehicle body cover constitutes the appearance of the vehicle and protects the internal components. The vehicle further includes the vehicle door assembly as described above, which is installed on the vehicle body. By integrating the optimized vehicle door assembly into the vehicle, the vehicle has a hidden vehicle-mounted object lifting mechanism. This design enables the vehicle-mounted object to be hidden inside the vehicle door when not in use, avoiding occupying the space inside the vehicle, while being able to be quickly lifted and extended to the window frame portion 2001 when needed, facilitating the passenger to use. This hidden storage function not only improves the neatness and aesthetics of the vehicle, but also enhances the user experience of the vehicle entertainment and life functions.

[0132] Finally, it should be explained that: the embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to each other.
