[0002] In the process of people traveling, more and more attention is paid to the comfort of riding, and the comfort of riding is not only the size of the space, but also the comfort of the seat. In order to improve the comfort of the car, a cup holder, a small table board and a car refrigerator are provided on some cars, especially on the rear seats. The small table board is generally located at the rear position. Among them, the central armrest is mainly provided on business cars, SUVs and other vehicles. The conventional central armrest is generally single-function, and the most common one is to provide two holes on the central armrest as a cup holder, which has great limitations and poor aesthetics, and low technology.

[0003] At the same time, for business personnel or other personnel, a small table board is generally provided in the car, such as the patent application number "202321922187.1" and the patent name "a pull-out foldable automobile seat table board". In this structure, the following disadvantages exist: 1. The table board is arranged on the backrest of the front seat. When the user uses it, the rear seat needs to be as close as possible to the front seat to facilitate the use of the table board. This makes it difficult for the user behind the table board to lean against the backrest of the corresponding seat, and the comfort of use is poor. 2. Due to the limited size of the table board, if a notebook computer is used, the optimal angle between the screen and the keyboard panel after the notebook computer is unfolded will exceed 100 degrees. The front side of the table board is the backrest of the front seat. After the screen is placed on the backrest of the front seat, the space available for the notebook computer on the table board is small. The rear half of the notebook computer is in a suspended state and is prone to falling, especially when the keyboard is struck. 3.

[0070] Refrigerator:

[0071] Referring to Figures 1-6 The refrigerator 4 is provided with a refrigeration cavity 41, a refrigerator opening 42 communicating with the refrigeration cavity 41 is arranged on the front side wall of the refrigerator 41, an ice box door 43 is arranged at the refrigerator opening 42, a refrigerator door driving part 44 and a refrigerator door storage groove 45 communicating with the refrigerator opening 42 are arranged on the refrigerator 4, and the refrigerator door driving part 44 is configured to drive the refrigerator door 43 to move, so that the refrigerator door 43 is retracted into the refrigerator door storage groove 45 or extends out of the refrigerator door storage groove 45, and the refrigerator opening 42 is opened or closed.

[0072] The refrigerator 4 is arranged on the rear side wall of the handrail main body 1 below the front side, and the bottom plane of the refrigerator opening 42 is arranged above the top plane of the rear end of the handrail main body 1. The front side of the refrigerator 4 is provided with a downwardly extending mounting part 46, and the refrigerator 4 is connected with the rear side wall of the handrail main body 1 through the mounting part 46.

[0073] In this embodiment, since the armrest body serves as a hand support position on the upper surface of the car seat, the refrigerator door is directly arranged on the front side wall of the refrigerator in this way, so that the height of the refrigerator opening is more suitable for the user to directly sit on the seat to take and place articles from the refrigeration cavity, improving the convenience and comfort of use. At the same time, the refrigerator is directly fixed on the armrest body, which does not occupy the space of the seat and the foot position, and as much as possible does not occupy the use space of the passengers in the car, reduces the interference of the refrigerator on the passengers, and improves the comfort of use of the passengers. And when the car stops or starts, the position of the refrigerator is fixed, and the problem of movement or impact of the refrigerator does not occur, and the safety is better.

[0074] At the same time, in this embodiment, the refrigerator door storage groove and the refrigerator door driving part are also arranged, and the refrigerator door driving part is driven in an electric manner, so that the user does not need to manually open the refrigerator door, and the convenience and comfort of use are more, and the sense of technology is stronger. The arrangement of the refrigerator door storage groove and the opening and closing mode of the refrigerator door do not occupy the space outside the refrigerator, further reducing the limitation of the use space of the refrigerator, reducing the space occupation, and since the refrigerator door does not occupy more space in the car, the user can take and place articles without being interfered by the refrigerator door, and the taking and placing is also convenient. In order to facilitate the driving of the refrigerator door, a controller is arranged on the armrest body for controlling the work of the refrigerator door driving part, so as to drive the opening and closing of the refrigerator door, and the refrigerator door driving part is powered by the car.

[0075] Referring to Figures 2-4 As shown in the figure, the refrigerator door storage groove 45 is arranged below the refrigerator opening 42, and the refrigerator door driving part 44 is arranged in the refrigerator door storage groove 45.

[0076] In this embodiment, the refrigerator door storage groove is arranged below the refrigerator opening, and the refrigerator door storage groove is arranged in the mounting part. In this structure, if the armrest is the armrest of the front seat (middle island), the refrigerator will be arranged in the front middle part of the rear seat, without directly occupying the space of the rear seat, or between the two front seats. If the armrest is the armrest of the rear seat, for example, the central armrest, the refrigerator (car refrigerator) will be arranged in the trunk (structure connecting the rear space and the trunk), or between the two rear seats, without occupying the use space of the passengers. At the same time, in this way, the refrigerator door driving part drives the refrigerator door to rise and extend out of the refrigerator door storage groove, for closing the refrigerator opening, or drives the refrigerator door to descend and retract into the refrigerator door storage groove, for storing and hiding the refrigerator door, without occupying space alone, improving the space utilization rate, and being more beautiful.

[0077] When the refrigerator door driving part drives the refrigerator door to move downwards and open the refrigerator opening, the refrigerator door moves partially or entirely into the refrigerator door storage groove; meanwhile, in this embodiment, when the refrigerator door moves downwards, the top of the refrigerator door moves downwards to separate from the top of the refrigerator opening, which realizes the gradual opening of the refrigerator opening until the top of the refrigerator door is close to the bottom of the refrigerator opening, or the bottom of the refrigerator door retracts into the refrigerator door storage groove, which completely opens the refrigerator opening.

[0078] When the refrigerator door driving part drives the refrigerator door to close the refrigerator opening, the top of the refrigerator door extends out of the refrigerator door storage groove. Since the refrigerator door driving part is in the refrigerator door storage groove, when the refrigerator opening is completely closed (the top of the refrigerator door abuts against the top surface of the refrigerator opening), the bottom of the refrigerator door is still in the refrigerator door storage groove for connection with the refrigerator door driving part. During the closing process of the refrigerator door, the refrigerator door driving part drives the refrigerator door to move upwards, which makes the refrigerator door gradually move upwards to separate from the refrigerator door storage groove until the top of the refrigerator door abuts against the top surface of the refrigerator opening, which completely closes the refrigerator opening.

[0079] Referring to Figure 5 , 6 As shown in the figure, at least one rack 430 is arranged on the rear side wall of the refrigerator door 43, and the rack 430 extends along the moving direction of the refrigerator door 43. The refrigerator door driving part 44 comprises a refrigerator door driving motor 440 and a refrigerator door driving gear 441. The refrigerator door driving gear 441 is engaged with the rack 430, and the refrigerator door driving motor 440 is configured to drive the rotation of the refrigerator door driving gear 441, and drives the movement of the refrigerator door 43 through the rack 430.

[0080] Through the structure of the gear and the rack, the rotation of the refrigerator door driving gear is driven by the refrigerator door driving motor, and the upward and downward movement of the refrigerator door is driven through the engagement between the rack and the refrigerator door driving gear, which realizes the opening and closing of the refrigerator opening. The motor driving structure can utilize the power supply of the automobile to realize the electric opening and closing of the refrigerator door, which is more scientific and functional.

[0081] The refrigerator opening and the refrigerator door are in an arc structure. The arc structure is a structure in which the middle part protrudes forward. This structure of the refrigerator door enables the person inside the vehicle to better observe the articles in the refrigeration chamber, facilitates the taking and placing of the articles, and the arc structure is not only beautiful but also not easy to hurt the user and safer and more convenient to clean.

[0082] Referring to Figure 5 , 6 As shown in the figure, the two racks 430 are arranged at intervals, and the racks 430 extend from top to bottom;

[0083] The refrigerator door driving gears 441 are two, each of which is engaged with one of the racks 430;

[0084] A gear connecting shaft 442 is further provided, and the two refrigerator door driving gears 441 are respectively installed at two ends of the gear connecting shaft 442. The refrigerator door driving motor 440 is configured to drive the gear connecting shaft 442 to rotate.

[0085] In this embodiment, two racks are adopted, and the two racks are respectively arranged near the two side edges of the refrigerator door. When the refrigerator door driving gears drive the refrigerator door to move up and down, the forces on the two sides are symmetrical and balanced, so as to ensure the stability and smoothness of the refrigerator door during opening and closing, and prevent the occurrence of jamming.

[0086] In order to ensure that the refrigerator door driving motor can smoothly drive the gear connecting shaft to rotate, a worm wheel 443 is arranged on the gear connecting shaft 442, and a worm gear 444 is arranged on the output shaft of the refrigerator door driving motor 440. The worm wheel 443 is engaged with the worm gear 444.

[0087] Since the engagement between the refrigerator door driving gear and the rack is not particularly tight, or the gear connecting shaft will rotate at a small angle when it is not driven, the refrigerator door will shake slightly after being opened or closed due to the vibration of the vehicle during operation, resulting in noise. Therefore, a second coil spring 445 is further sleeved on the gear connecting shaft 442. One end of the second coil spring 445 is connected with the gear connecting shaft 442, and the other end of the second coil spring 445 is connected with the refrigerator 4. The second coil spring always gives the gear connecting shaft a force in one direction, so that the gear connecting shaft drives the refrigerator door driving gear to abut against the rack, thereby preventing the refrigerator door from shaking and other problems. Of course, the second coil spring can also not be provided, and some elastic members can be arranged on the refrigerator door to resist the opening of the refrigerator door, and the shaking or noise will not occur.

[0088] Referring to Figure 3 , 4 As shown in the figure, the inner wall of the refrigerator opening 42 is provided with a limiting groove 420, and the outer edge of the refrigerator door 43 is arranged in the limiting groove 420. The limiting groove is arranged to limit the movement track of the refrigerator door, and the bottom of the limiting groove is in communication with the refrigerator door receiving groove.

[0090] Referring to Figures 7-11As shown, the tray component 3 comprises a tray body 31 and a tray driving part 32, the tray driving part 32 is arranged below the tray body 31, the tray driving part 32 is configured to drive the tray body 31 to rise and fall;

[0091] When the tray driving part 32 drives the tray body 31 to fall to the lowest point, the tray body 31 is completely retracted in the tray component accommodating cavity 12, and the top surface of the tray body 1 is arranged flush with the top of the tray component accommodating cavity 12, or the top surface of the tray body 31 is arranged close to the top of the tray component accommodating cavity 12;

[0092] When the tray driving part 32 drives the tray body 31 to rise to the highest point, the top of the tray body 31 protrudes out of the tray component accommodating cavity 12 and is arranged above the top of the handrail body 31.

[0093] In this embodiment, when the tray component is not used, it is completely inside the handrail body, and because when the tray body falls to the lowest point, the top surface of the tray body is flush with the top of the tray component accommodating cavity or is arranged close to the top thereof (preferably the top surface of the tray body is flush with the top of the accommodating cavity, so that the top surface of the tray body serves as part of the top surface of the handrail body), so that there is no recess on the top of the handrail body, which does not affect the normal use of the handrail body as a handrail. When the tray body is needed, the tray driving part works to push the tray body to rise out of the tray component accommodating cavity (the rising height can be adjusted arbitrarily), so that the tray body can be normally used as a "small table board" or for normal storage. In the utility model, the electrically driven tray body moving mode is more advanced and has more technological sense.

[0094] Referring to Figures 7-11 As shown, the tray body 31 is connected with the tray driving part 32 through a tray support 33, and the bottom of the tray body 31 is rotationally connected with the top of the tray support 33 through a tray turntable 34.

[0095] The tray body is connected with the tray support and the tray driving part, the tray body serves as a supporting component, in order to facilitate the adjustment of the angle and position thereof, therefore, the tray body is rotationally connected with the top of the tray support through the tray turntable, especially if the tray body adopts a non-circular structure, so that the rotation angle of the tray body can be adapted to the best angle and position of the user, improving the comfort and convenience of the user; even if the tray body adopts a regular circular structure, the angle of the article placed on the tray body (such as a notebook computer) can be adjusted by rotating the angle of the tray body, so that the article is prevented from falling off the tray body by rotating the angle of the article.

[0096] If the tray body can only be connected with the tray turntable and the tray support through rotation, the tray body can only be above the armrest body when in use, and the use mode has certain limitations. Further, the bottom of the tray body 31 is slidably arranged on the tray turntable 34 through the slide rail 35. Therefore, through the arrangement of the slide rail, the tray body can be slid to the side of the tray support, i.e., to the side of the armrest body, so that it can be moved to the position of the car seat or directly face the user, improving the comfort of the user.

[0097] The slide rail is a damping slide rail. The tray turntable is rotationally connected with the tray support through a damping member. In this way, the tray body can be moved or rotated to any position and will stay at the position, preventing sudden movement and ensuring stability in use.

[0098] Referring to Figure 11 As shown, the tray body 31 includes a main tray 310 and side trays 311 respectively hingedly arranged on both sides of the main tray 310. The bottom of the main tray 310 is arranged on the tray turntable 34 (in this way, no slide rail is arranged) or is arranged on the tray turntable 34 through the slide rail 35 (in this way, a slide rail is arranged). The side trays 311 have an unfolded state and a folded state. In the folded state, the side trays 311 are flipped and rest on the top surface of the main tray 310. In the unfolded state, the side trays 311 are arranged beside the main tray 310. In the folded state, the tray body can be completely retracted into the tray component accommodating cavity.

[0099] The side walls of the side trays are hingedly connected with the side walls of the main tray. Due to the existence of the hinges, the side trays can be rotated towards the top of the main tray and rest on the main tray. When the side trays are unfolded by being flipped outwards, the side walls of the side trays can limit the side trays from being flipped downwards and further limit the flipping angle of the side trays. In the unfolded state of the side trays, the top surface of the side trays is flush with the top surface of the main tray. Further, in the unfolded state of the side trays, the top surface of the main tray and the top surface of the side trays can be provided with an anti-slip layer to prevent the materials placed on the top surface of the tray body from easily sliding and falling. In the folded state of the side trays, the top surface of the side trays faces downwards and rests on the top surface of the main tray. The existence of the side trays and the main tray can unfold the side trays when in use, so that the area of the tray body is larger and more articles can be placed thereon. Of course, according to actual conditions, the side trays can also not be unfolded when in use. When the tray body is not in use, the side trays can be directly folded and then normally accommodated in the tray component accommodating cavity. In this embodiment, the opening size of the top of the tray component accommodating cavity matches the size of the tray body after the side trays are folded, or is slightly larger. In this way, after the tray body is completely accommodated in the tray component accommodating cavity, the top of the tray component accommodating cavity is basically covered.

[0100] Referring to Figure 9 As shown, the tray support 34 is further provided with a storage groove 340, which is in communication with at least one side outer wall of the tray support 34.

In this way, after the tray driving part drives the tray main body to rise, the storage groove is exposed on the top of the handrail main body, and the user can put some articles into the storage groove. Alternatively, the tray support directly adopts a U-shaped structure or a box-shaped structure with an opening on one side, and the inside of the tray support forms the storage groove.

[0102] Referring to Figure 10 , 11 As shown, the tray driving part 32 comprises a tray driving motor 320 and a tray jacking frame 321, the top of the tray jacking frame 321 is connected with the bottom of the tray main body 31, the bottom of the tray jacking frame 321 is connected with the tray part accommodating cavity 12, the tray driving motor 320 is installed in the tray part accommodating cavity 12 or on the tray jacking frame 321, the working end of the tray driving motor 320 is provided with a screw rod 322 connected with the tray jacking frame 321, the tray driving motor 320 drives the screw rod 322 to extend and retract, and drives the top of the tray jacking frame 321 to rise or fall. The tray driving motor is powered by an external power supply mechanism, for example, the automobile powers the tray driving motor.

[0103] In the utility model, the tray jacking frame has multiple structures, the first kind: including two groups of side frames and an intermediate shaft, the middle parts of the two groups of side frames are rotationally connected with the intermediate shaft, the two groups of side frames are a first side frame and a second side frame, the bottom of the first side frame is rotationally installed on the bottom left side rotationally connected with the tray part accommodating cavity, the top of the first side frame is rotationally connected with the top right side of the tray support, the top of the second side frame is rotationally connected with the top left side of the tray support, and the bottom of the second side frame is slidingly connected with the bottom of the tray part accommodating cavity. The tray driving motor is rotationally installed on the bottom of the tray part accommodating cavity, its driving screw rod rotates (has a screw rod frame, the screw rod frame has a nut screw connected with the screw rod, and the tray driving motor drives the nut to rotate), and the top of the screw rod is rotationally connected with the second side frame, and the rotationally connected part is above the intermediate shaft. When the screw rod extends and retracts, the bottom of the second side frame is driven to be close to or away from the bottom of the first side frame, so that the tops of the two groups of side frames rise or fall.

[0104] The second structure of the tray jacking frame (adopted in the embodiment): referring to Figure 11As shown, the system includes a lower frame 3210, an upper frame 3211, and an intermediate frame 3212. The upper frame 3211 is fixedly mounted on the bottom surface of the pallet bracket 33. The left side of the lower frame 3210 is connected to the left side of the pallet component receiving cavity 12, and the middle part of the lower frame 3210 is connected to the pallet receiving cavity 12. The top of the intermediate frame is rotatably connected to the bottom of the lower frame, and the middle part of the intermediate frame is rotatably connected to the middle part of the lower frame. A screw bracket 323 is rotatably mounted on the right side of the lower frame. The screw bracket contains a nut that is screwed to the screw. The middle part of the screw 322 is screwed to the nut. The pallet drive motor 320 is mounted on the right side of the lower frame and drives the nut to rotate. The top of the screw is rotatably connected to the right end of the intermediate frame. When the pallet drive motor rotates the nut, it causes the screw to rise and fall relative to the nut. When the top of the screw rises, it causes the intermediate frame to rotate counterclockwise around the lower frame (the direction of rotation is shown in the diagram), causing the left end of the intermediate frame to fall, thereby causing the upper frame and pallet support to fall, thus lowering the pallet body. When the top of the screw falls, it causes the intermediate frame to rotate clockwise around the lower frame, causing the left end of the intermediate frame to rise, thereby pushing the upper frame and pallet support to rise, thus raising the pallet body.

[0105] Of course, the pallet lifting frame also has other structures. By extending and retracting the screw, the top of the pallet lifting frame can be moved upward. For example, the top of the pallet lifting frame is fixed to the pallet bracket, the bottom of the pallet lifting frame is slidably connected to the handrail body, the top of the screw is connected to the pallet lifting frame, and the pallet drive motor drives the screw to rise and fall, thereby pushing the pallet lifting frame to rise and fall.

[0107] See Figure 7 , 12 As shown in Figure 15, the cup holder component 2 includes a cup holder body 21 and a cup holder drive unit 22. The cup holder drive unit 22 is configured to drive the cup holder body 21 to rise and move above the top surface of the armrest body 1, or to descend and retract into the cup holder component receiving cavity 11.

[0108] A cup holder cover 23 is rotatably mounted on the armrest body 1. The cup holder drive unit 22 is driven by a counterweight to rotate the cup holder cover 23. When the cup holder body 1 is lowered to the storage position, the cup holder cover 23 rotates to the top of the cup holder body 21. When the cup holder body 21 is raised to the use position, the cup holder cover 23 rotates to the side of the cup holder body 21 or rotates into the cup holder component receiving cavity 11.

[0109] In this embodiment, the cup holder component accommodating cavity is used to accommodate the cup holder component and the cup holder cover plate, wherein the cup holder body top has a cup accommodating slot for placing and limiting the cup. When the cup holder body is not in use, the cup holder driving part drives the cup holder body to descend and retract into the accommodating cavity. At this time, the cup holder body descends to the lowest point and is completely in the cup holder component accommodating cavity. At this time, the cup holder body is in the storage position. Meanwhile, the cup holder cover plate is also driven to rotate above the cup holder body during this process. During this process, the cup holder cover plate is at the top of the cup holder component accommodating cavity, which is arranged in a flush manner with the top surface of the cup holder component accommodating cavity, or the top surface of the cup holder cover plate is slightly lower than the top surface of the cup holder component accommodating cavity. Preferably, the top surface of the cup holder cover plate is flush with the top surface of the cup holder component accommodating cavity. In this way, the cup holder component accommodating cavity can be covered and not exposed, and can be used as a support component of the handrail body. When the user uses the handrail body, the handrail body will not touch the hand, which is more stable. When the cup holder body is raised for use (when the cup holder body rises to the highest point, the cup holder body is in the use position and the top thereof is exposed above the top of the handrail body), the cup holder cover plate is rotated to the side of the raised cup holder body or into the cup holder component accommodating cavity, so as to expose the cup accommodating slot of the cup holder body top plate and not affect the normal placement of the cup. In this embodiment, when the cup holder body is extended to the use position, the cup holder cover plate is rotated into the cup holder component accommodating cavity.

In use, the cup holder driving motor drives the cup holder driving shaft to rotate. Due to the existence of the cam, the distance from the outer surface of the cam at different positions to the axis of the cup holder driving shaft is different, and the reset force of the elastic reset member always pulls the bottom of the cup holder body to move downward and abuts against the outer surface of the cam. When the cup holder driving shaft rotates, the cam rotates, so as to push the cup holder body to move upward. The elastic reset member pulls the cup holder body to move downward, so as to realize the stable upward movement and downward movement of the cup holder body. In particular, when the cup holder body moves upward to the predetermined position, the bottom of the cup holder body is supported by the cam, so as to prevent the cup holder body from moving downward due to the weight of the cup.
