[0035] Please refer to Figure 1 、 Figure 2 and Figure 6 , an access mechanism 11 provided by an embodiment of the present utility model is used for a vehicle-mounted refrigerator 1. The access mechanism 11 includes a base 111, an upper cover 112 and a driving assembly 113. The driving assembly 113 includes a driving member 1131 and a transmission assembly 1132. The upper cover 112 is slidably connected to the base 111. The driving member 1131 is connected to the upper cover 112 through the transmission assembly 1132 and is used to drive the transmission assembly 1132 to drive the upper cover 112 to slide and lock the upper cover 112. The driving member 1131 includes a self-locking gear.

[0036] Specifically, as Figure 6As shown in the figure, the in-vehicle refrigerator 1 includes an access mechanism 11, a drawer 12, and a box body 13. The access mechanism 11 is a mechanical device for the in-vehicle refrigerator 1, used to realize the access of the drawer 12 to and from the box body 13. Among them, the drawer 12 is arranged on the upper cover 112. When the driving member 1131 drives the transmission assembly 1132 to drive the upper cover 112 to slide, the drawer 12 slides along with the upper cover 112, thereby realizing the opening and closing of the drawer 12 of the in-vehicle refrigerator 1.

[0037] The base 111 is fixed inside the box body 13, and the upper cover 112 is slidably connected to the base 111, cooperating with the drawer 12 to realize the opening and closing function of the drawer 12. The driving member 1131 is fixedly connected to the base 111 and is connected to the upper cover 112 through the transmission assembly 1132, responsible for driving the sliding and locking of the upper cover 112. The transmission assembly 1132 transmits the power of the driving member 1131 to the upper cover 112, thereby controlling the sliding and locking of the upper cover 112.

[0038] The driving member 1131 includes a self-locking gear, and the driving member 1131 is a gear motor. The design of the gear is closely related to friction. The specific gear design enables the gear motor to have a certain self-locking ability, that is, through the friction of the gear system, the drawer 12 can be fixed to a certain extent, thereby preventing the output shaft of the gear motor from rotating under the influence of a slight external force. When the external force is large enough, the output shaft of the gear motor can rotate under the action of the external force to drive the upper cover 112 to slide, realizing the function of manually opening and closing the drawer 12 when the power is off. Exemplarily, the gear motor may include, but is not limited to, a DC motor, an AC motor, a stepper motor, a brushless DC motor, a servo motor, and a brushless servo motor, etc. Exemplarily, the specific gear design may be a helical gear or a bevel gear, etc.

[0039] In the above access mechanism 11, the upper cover 112 can be connected to the drawer 12. When the driving member 1131 is powered off, the self-locking gear can be unlocked, so that when the driving member 1131 is powered off, the user can manually open and close the drawer 12.

[0040] Optionally, the outer layer of the driving member 1131 is wrapped with a silica gel sleeve for reducing noise and waterproofing.

[0041] Further, in some embodiments, the self-locking gear includes a first gear and a second gear, the second gear is connected to the output shaft of the driving member 1131, and the first gear is meshed and connected to the second gear.

[0042] Specifically, when the driving member 1131 is powered on and the user inputs an instruction to open the vehicle or close the refrigerator on the vehicle, the first gear drives the second gear to rotate through meshing, thereby driving the output shaft of the driving member 1131 to rotate. When the driving member 1131 is powered off and the user manually opens or closes the refrigerator, the output shaft of the driving member 1131 drives the second gear to rotate. The second gear overcomes the frictional force between the first gear and the second gear under an external force and drives the first gear to rotate through meshing.

[0043] In the above embodiment, through the interaction between the first gear and the second gear, the vehicle-mounted refrigerator 1 can be electrically opened or closed when powered on, and can be manually opened or closed when powered off.

[0044] Further, please refer to Figure 1 , in an alternative embodiment, the base 111 is provided with a receiving groove 1111, and a part of the transmission assembly 1132 is received in the receiving groove 1111.

[0045] Specifically, the receiving groove 1111 refers to a groove or cavity provided on the base 111, and its shape and size are designed to match the transmission assembly 1132. The receiving groove 1111 is used to provide a suitable installation position for the transmission assembly 1132 so that it can be partially embedded inside the base 111.

[0046] In the above embodiment, by embedding a part of the transmission assembly 1132 into the receiving groove 1111 in the base 111, the overall volume occupied by the transmission assembly 1132 can be reduced, making the overall design of the access mechanism 11 more compact. Further, please refer to Figure 3 , in some embodiments, the transmission assembly 1132 includes a first wheel 11321, a transmission member 11322, and a second wheel 11323. The first wheel 11321 and the second wheel 11323 are rotatably provided on the base 111. The first wheel 11321 is connected to the output shaft of the driving member 1131. The transmission member 11322 is sleeved outside the first wheel 11321 and the second wheel 11323, and the upper cover 112 is fixed on the transmission member 11322.

[0047] Specifically, the first wheel 11321 rotates under the action of the output shaft of the driving member 1131, driving the transmission member 11322. The transmission member 11322 transmits power to the second wheel 11323 under the rotation of the first wheel 11321 to make the second wheel 11323 rotate, thereby realizing the overall movement of the transmission member 11322 driving the upper cover 112 to slide.

[0048] In the above embodiment, through the transmission of the transmission member 11322, the upper cover 112 is driven to slide, thereby realizing the opening and closing function of the drawer 12 of the vehicle-mounted refrigerator 1.

[0049] Further, in some embodiments, the transmission member 11322 includes one of a synchronous belt, a chain, or a rope.

[0050] Specifically, the transmission member 11322 can be implemented in various forms according to actual requirements and application environments to achieve the transmission function. In the above embodiments, the diverse design of the transmission member 11322 can improve the adaptability to different scenarios and enhance flexibility.

[0051] Further, please refer to Figure 3 , in some embodiments, the transmission assembly 1132 includes a pressing wheel 11324. The pressing wheel 11324 is rotatably provided on the base 111. The pressing wheel 11324 is provided between the first wheel 11321 and the second wheel 11323. The pressing wheel 11324 abuts against the outer side of the transmission member 11322 away from the upper cover 112.

[0052] Specifically, the pressing wheel 11324 abuts against the transmission member 11322 so that the transmission member 11322 is away from the bottom of the receiving groove 1111, so that when the transmission member 11322 moves, it is not affected by the bottom of the receiving groove 1111.

[0053] In the above embodiments, by the pressing wheel 11324 abutting against the outer side of the transmission member 11322 away from the upper cover 112, the transmission member 11322 is away from the bottom of the receiving groove 1111, thereby preventing damage or jamming of the transmission member 11322 caused by friction with the bottom of the receiving groove 1111 during the transmission process, and improving the transmission efficiency.

[0054] Further, please refer to Figure 3 , in some embodiments, a fixing member 11325 is provided on the transmission member 11322, and the fixing member 11325 is fixedly connected to the upper cover 112.

[0055] Specifically, the fixing member 11325 is fixedly connected to the transmission member 11322 and has two first through holes. The upper cover 112 is provided with second through holes corresponding to the two first through holes. Optionally, the connection between the fixing member 11325 and the upper cover 112 is fastened by inserting screws into the first through holes and the second through holes.

[0056] In the above embodiments, the upper cover 112 is fixedly connected to the transmission member 11322 through the fixing member 11325, ensuring that the upper cover 112 slides under the driving action of the transmission member 11322, thereby improving the transmission effectiveness of the transmission member 11322.

[0057] Further, please refer to Figure 1 , in an alternative embodiment, the feeding and discharging mechanism 11 includes a slide rail 1141 assembly. The slide rail 1141 assembly connects the upper cover 112 and the base 111.

[0058] Exemplarily, the slide rail 1141 assembly is disposed on both sides of the base 111 perpendicular to the sliding direction of the upper cover 112, and is detachably connected to the upper cover 112 to ensure that the upper cover 112 can slide smoothly along the slide rail 1141 assembly.

[0059] In the above embodiment, the slide rail 1141 assembly can effectively guide the sliding of the upper cover 112, reduce friction and jamming phenomena, thereby improving the stability and smoothness of the upper cover 112 during the sliding process.

[0060] Further, please refer to Figure 1 , in an alternative embodiment, the slide rail 1141 assembly includes a slide rail 1141 and a slide groove 1142. One of the slide rail 1141 and the slide groove 1142 is disposed on the upper cover 112, and the other is disposed on the base 111. The slide rail 1141 is in sliding fit with the slide groove 1142.

[0061] Exemplarily, the slide groove 1142 is fixed on both sides of the base 111 perpendicular to the sliding direction of the upper cover 112. The slide rail 1141 is provided with a buckle, and the upper cover 112 is provided with a slot corresponding to the buckle. The slide rail 1141 is connected to the upper cover 112 by snapping the buckle into the slot of the upper cover 112. After the slide rail 1141 and the upper cover 112 are connected, the driving member 1131 drives the upper cover 112 to slide through the transmission member 11322. At the same time, the upper cover 112 will drive the slide rail 1141 to slide in the slide groove 1142 through the buckle.

[0062] In an alternative embodiment, the slide groove 1142 is provided with a self-locking seat, the slide rail 1141 is provided with a self-locking piece, and a spring is connected between the self-locking seat and the self-locking piece.

[0063] Specifically, when the drawer 12 is in the closed state, the spring is in the natural state or the extended state.

[0064] In the above embodiment, through the spring force, the slide rail 1141 can be fixed to a certain extent, thereby fixing the drawer 12 by fixing the upper cover 112 to prevent the drawer 12 from being opened under the influence of slight external force. When the external force is large enough, for example, when the driving member 1131 drives or manually opens the drawer 12, the upper cover 112 will drive the slide rail 1141 to overcome the spring force, thereby realizing the opening function of the drawer 12.

[0065] Further, please refer to Figure 1 and Figure 4 , in an alternative embodiment, the access mechanism 11 includes a first limiting member 1121 and a second limiting member 1112 arranged along the sliding direction of the upper cover 112. The first limiting member 1121 is disposed on the upper cover 112, the second limiting member 1112 is disposed on the base 111, and the second limiting member 1112 and the first limiting member 1121 are cooperatively connected to limit the sliding stroke of the upper cover 112.

[0066] Specifically, two second limiting members 1112 are provided on the base 111. The first limiting member 1121 is a stopper fixed on the upper cover 112, and the second limiting member 1112 is a stopper fixed on the base 111. The two second limiting members 1112 are respectively arranged at both ends of the base 111. The first limiting member 1121 moves between the two second limiting members 1112 under the action of physical obstruction, thereby restricting the moving range of the upper cover 112 in the sliding direction.

[0067] In the above embodiment, the upper cover 112 moves within a certain sliding range through the first limiting member 1121 and the second limiting member 1112, ensuring that the upper cover 112 does not slide out of the box body 13, thereby avoiding the situation where the drawer 12 slides out of the box body 13.

[0068] Further, please refer to Figure 1 , in some embodiments, the access mechanism 11 includes an acceleration sensor 115. The acceleration sensor 115 is installed on the base 111. The acceleration sensor 115 is electrically connected to the driving member 1131. The acceleration sensor 115 is configured to detect the acceleration of the base 111, and the driving member 1131 is configured to lock the upper cover 112 when the acceleration of the base 111 is greater than or equal to a set value.

[0069] Specifically, during the driving process of the vehicle, there are extreme working conditions such as emergency braking (sudden braking), emergency acceleration or collision. The self-locking force of the slide rail 1141 or the motor is limited, and the drawer 12 may move due to excessive external force. Therefore, by introducing the acceleration sensor 115 to detect the acceleration of the base 111, that is, to detect the acceleration of the vehicle, when the acceleration is greater than or equal to the set value, the upper cover 112 is locked, thereby ensuring that the drawer 12 will not be displaced under extreme working conditions. Exemplarily, the set value can be 0.5g, where g is the gravitational acceleration constant, approximately 9.81m / s 2 .

[0070] In the above embodiment, by detecting the acceleration of the base 111 through the acceleration sensor 115 and locking the upper cover 112 when the acceleration is greater than or equal to the set value, it can be ensured that in the event of extreme working conditions, the drawer 12 is locked to prevent the drawer 12 from moving under the action of external force.

[0071] In an alternative embodiment, the acceleration sensor 115 may include, but is not limited to, a microelectromechanical system acceleration sensor, a uniaxial acceleration sensor, a triaxial acceleration sensor, a piezoelectric acceleration sensor, a capacitive acceleration sensor, an optical fiber acceleration sensor, and an inertial measurement unit, etc.

[0072] Optionally, there are multiple ways to lock the upper cover 112. In one embodiment, the driving member 1131 is a motor, and the motor is locked by short - circuiting the winding wires of the motor. Any external force attempting to rotate the output shaft of the motor will generate an induced current, which will flow in the short - circuit loop and generate an electromagnetic force opposite to the direction of the external force, thereby canceling out the external force and achieving locking. In one embodiment, the driving member 1131 is a motor, and a brake disc is connected to the output shaft of the motor. The brake disc clamps the output shaft of the motor through a braking device (such as an electromagnetic brake or a mechanical brake) to prevent the output shaft of the motor from rotating, thereby locking the upper cover 112.

[0073] Further, please refer to Figure 5 , in some embodiments, the acceleration sensor 115 includes a weight 1151 and a micro - switch 1152. The weight 1151 is movably arranged on the base 111, and the weight 1151 is configured to trigger the micro - switch 1152 to lock the upper cover 112 by the driving member 1131 when the acceleration of the base 111 is greater than or equal to a set value.

[0074] Specifically, during vehicle driving, in the case of extreme working conditions such as emergency braking (sudden braking), that is, when the acceleration of the base 111 is greater than or equal to the set value, the weight 1151 will impact the micro - switch 1152 under the action of inertia, thereby triggering the micro - switch 1152. After the system receives the switch signal sent by the micro - switch 1152, it generates a braking signal and sends it to the driving member 1131 to lock the upper cover 112 by the driving member 1131. Optionally, the system can be the system of the vehicle refrigerator 1 or the system of the vehicle. Exemplarily, the mass of the weight 1151 can be 20 g. The elastic force of the micro - switch 1152 can be 2 N.

[0075] Optionally, the number of micro - switches 1152 can be one or two. In one embodiment, the acceleration sensor 115 includes one micro - switch 1152, which is arranged on one side of the weight 1151. When the vehicle accelerates or decelerates emergently, the weight 1151 impacts the micro - switch 1152 under the action of inertia, thereby triggering the micro - switch 1152 to lock the upper cover 112 by the driving member 1131. In one embodiment, the acceleration sensor 115 includes two micro - switches 1152, which are arranged on both sides of the weight 1151. The weight 1151 impacts the micro - switch 1152 under the action of inertia, thereby triggering the micro - switch 1152 to lock the upper cover 112 by the driving member 1131.

[0076] In the above - mentioned embodiments, by detecting the acceleration of the base 111 through the weight 1151 and the micro - switch 1152 and locking the upper cover 112 when the acceleration is greater than or equal to the set value, it can be ensured that in the case of extreme working conditions, the drawer 12 is locked to prevent the drawer 12 from moving under the action of external force.

[0077] It is understandable that in some embodiments, the driving member 1131 includes a stall sensor. The stall sensor is configured to detect the stall state of the driving member 1131. During the sliding process of the driving member 1131 driving the upper cover 112, when the driving member 1131 is in a stall state, the driving member 1131 stops driving the upper cover 112 to slide.

[0078] Stall means that the driving member 1131 is in a state where it cannot continue to rotate during operation due to excessive load, mechanical jamming, or other reasons. At this time, the driving member 1131 is still powered on, but the output shaft does not rotate or rotates very slowly.

[0079] Due to the risk of pinching hands or the driving member 1131 being accompanied by excessive current consumption and overheating in the stall state, therefore, the driving member 1131 detects the stall state through the stall sensor and stops operating when a stall state occurs, thereby realizing the function of preventing pinching hands or protecting the driving member 1131. Optionally, the stall sensor can be an angle sensor, and the angle sensor is used to detect the rotation angle of the driving member 1131. The angle sensor can be one or several of a Hall sensor, a potentiometer, and an encoder.

[0080] In the above embodiments, by the stall sensor stopping the driving member 1131 from operating in a timely manner when detecting a stall state, the function of preventing pinching hands of the vehicle-mounted refrigerator 1 can be realized, the damage to the driving member 1131 can be reduced, and the service life of the driving member 1131 can be extended.

[0081] In one embodiment, during the process of opening or closing the drawer 12, the driving member 1131 drives the upper cover 112 to slide through the transmission assembly 1132 until the first limiting member 1121 abuts against the second limiting member 1112. At this time, the stall sensor detects that the driving member 1131 is in a stall state, and the driving member 1131 stops operating.

[0082] Please refer to Figure 6 , the vehicle-mounted refrigerator 1 according to the embodiment of the present invention includes a box body 13, a drawer 12, and the access mechanism 11 according to any of the above embodiments. The upper cover 112 of the access mechanism 11 is fixedly connected to the drawer 12, and the base 111 of the access mechanism 11 is fixedly connected to the box body 13. The driving assembly 113 drives the drawer 12 to enter or exit the box body 13 or locks the drawer 12 by driving or locking the upper cover 112, thereby realizing the opening, closing, and locking of the drawer 12 of the vehicle-mounted refrigerator 1.

[0083] The vehicle according to the embodiment of the present invention includes the vehicle-mounted refrigerator 1 according to any of the above embodiments.

[0084] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification. At the same time, other embodiments can be derived from the above embodiments, so that structural and logical substitutions and changes can be made without departing from the scope of the present disclosure.
