DETAILED DESCRIPTION

[0019] ​The technical solutions in the embodiments (or, modes of implementation) of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0020] If the present application embodiments involve directional indications or positional relationships (for example, up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between components in a certain posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. in the present application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0021] The present application provides a refrigerator unlocking device, a vehicle-mounted refrigerator and a vehicle, which will be described in detail below in conjunction with the accompanying drawings. The features in the following embodiments and modes of implementation can be combined with each other without conflict.

[0022] The present application embodiment provides a refrigerator unlocking device, which refers to Figures 1 to 6 The refrigerator unlocking device includes a key structure 10, a first wire harness 20, a controller 30 and an unlocking assembly 40.

[0023] The key structure 10 is used to generate a first unlocking signal after being pressed. At least part of the first wire harness 20 is set as a spring wire harness 221, the controller 30 is electrically connected with the key structure 10 through the first wire harness 20, and is used to generate an unlocking instruction according to the first unlocking signal, and the unlocking assembly 40 is electrically connected with the controller 30, and is used to unlock according to the unlocking instruction. The use process of the refrigerator unlocking device is as follows: the key structure 10 generates a first unlocking signal after being pressed, and transmits the first unlocking signal to the controller 30 through the first wire harness 20, the controller 30 generates an unlocking instruction in response to the first unlocking signal, and transmits the unlocking instruction to the unlocking assembly 40 through wired or wireless (such as Bluetooth, wifi, star flash, etc.), and the unlocking assembly 40 is unlocked in response to the unlocking instruction.

[0024] It is easy to understand that the key structure 10 with the entity has a clear pressing range and tactile feedback, and the user can perceive whether the key structure 10 is pressed through the sense of touch, and then determine whether the unlocking operation is successful, without relying on visual confirmation, which is especially suitable for scenes with relatively dim light (such as at night). In addition, at least part of the first wire harness 20 adopts a spring wire harness 221, which has the characteristics of stretching and contracting and is not limited by the fixed length of the cable. The drawer 72 and other load members of the vehicle-mounted refrigerator have linear displacement during opening and closing. The traditional fixed-length wire harness is prone to wear, breakage and other problems due to pulling, bending and other factors. In the present scheme, the spring wire harness 221 can stretch and contract with the drawer 72 and other load members, reducing the risk of damage to the first wire harness 20. For example, when the user pulls out the drawer 72, the spring wire harness 221 is elongated, and when the user retracts the drawer 72, the spring wire harness 221 is retracted. Moreover, the stretching and contracting characteristics of the spring wire harness 221 do not require a long redundant cable, which can be arranged compactly in the limited internal space of the vehicle-mounted refrigerator, avoiding messy cable accumulation and occupying storage space.

[0025] In some embodiments, the key structure 10 can include a key body and a trigger component located within the pressing stroke of the key body. The trigger component can be a trigger switch or a pressure sensor. When the user presses the key body, the trigger switch is closed or the pressure sensor detects pressure, thereby converting the user's pressing action into a first unlocking signal and sending it to the controller 30 through the first wire harness 20, so that the controller 30 performs subsequent actions. The key body can be built-in with a return spring, and the key body can automatically rebound to the initial position after being pressed, so that the user performs the next pressing action. It should be noted that the specific structure of the key body can refer to related technologies, and this specification does not make specific limitations.

[0026] In some embodiments, the refrigerator unlocking device further includes a touch structure for generating a second unlocking signal after being touched, and the controller 30 is electrically connected with the touch structure. The controller 30 is configured to generate an unlocking instruction according to the first unlocking signal or the second unlocking signal.

[0027] In this way, the user can use the touch structure or the key structure 10 to unlock according to his own needs and preferences. For example, in the case of driving, in a dim light environment, etc., the user can unlock by blind operation through the key structure 10. In the case of a stationary vehicle and good light, the user can unlock the refrigerator through the touch structure. In particular, when one of the key structure 10 and the touch structure is damaged, the user can achieve unlocking through the other one, which improves the reliability of the refrigerator unlocking device.

[0028] It should be noted that the touch structure can refer to related technologies, for example, the touch structure can be integrated into the display screen of the vehicle-mounted refrigerator, or the touch structure can be the central control screen of the vehicle or the terminal device of the user in some schemes. The controller 30 can be but is not limited to a single-chip microcomputer, a circuit board, etc., which can refer to related technologies. The present specification does not make specific limitations on this.

[0029] In some embodiments, the refrigerator unlocking device further comprises a wire harness support 50 extending along the length direction of the spring wire harness 221, and the spring wire harness 221 is accommodated in the wire harness support 50.

[0030] It is easy to understand that the spring wire harness 221 can be wound and hooked to the surrounding structure due to its telescopic characteristics, causing deformation, inability to rebound, and even damage. Therefore, the wire harness support 50 accommodates the spring wire harness 221 to isolate the spring wire harness 221 from the surrounding structure, preventing the spring wire harness 221 from being abraded, scratched, and the like. At the same time, the extension direction of the wire harness support 50 is consistent with the length direction (axial direction) of the spring wire harness 221, so that the spring wire harness 221 can normally stretch and retract, and play a normal electrical connection role.

[0031] Further, the wire harness support 50 comprises a support body 51 and a reinforcing structure 52, the support body 51 is a semi-enclosed structure, the spring wire harness 221 is located in the support body 51, and the reinforcing structure 52 is arranged on the outer wall of the support body 51. The reinforcing structure 52 can be integrally formed with the support body 51, but is not limited thereto.

[0032] Firstly, the semi-enclosed support body 51 can leave an opening for the spring wire harness 221 to be put in, taken out and maintained, thereby simplifying assembly. Secondly, the reinforcing structure 52 can improve the strength of the support body 51 and the impact resistance of the support body 51, adapt to the bumping of the vehicle during driving, and improve the service life.

[0033] Specifically, the reinforcing structure 52 comprises a plurality of reinforcing ribs, the reinforcing ribs are arranged at intervals along the length direction of the support body 51, and each reinforcing rib extends along the circumferential direction of the support body 51 to better reinforce the support body 51.

[0034] In some embodiments, the first wire harness 20 comprises a first portion 21, a second portion 22 and a third portion 23 connected in sequence, the first portion 21 is connected with the button structure 10, the second portion 22 comprises the spring wire harness 221, the second portion 22 is located in the wire harness support 50, and the third portion 23 is connected with the controller 30.

[0035] It is easy to understand that the connection section of the key structure 10 and the controller 30 needs stable connection, if the spring wire harness 221 is directly connected, the elastic deformation of the spring wire harness 221 is easy to cause the connection interface to be loose and the contact to be poor. Therefore, in the present scheme, only the second part 22 includes the spring wire harness 221, and the first part 21 connected with the key structure 10 and the third part 23 connected with the controller 30 can adopt a conventional wire harness to ensure the stability of the connection.

[0036] In some embodiments, the refrigerator unlocking device further comprises a first limiting piece 61, which is arranged at the connection between the first part 21 and the second part 22, and is used for limiting one end of the first part 21 close to the second part 22.

[0037] In this way, one end of the first part 21 is connected with the key structure 10, and the other end is limited by the first limiting piece 61, so that the first part 21 is limited between the controller 30 and the first limiting piece 61, reducing the risk of the first part 21 being separated from the key structure 10 due to pulling.

[0038] In the embodiment as shown in the drawings, the cable support is provided with a baffle 53 at the connection between the first part 21 and the second part 22, the baffle 53 is provided with a through hole, and the first wire harness 20 can pass through the through hole to pass through the baffle 53, wherein the first part 21 of the first wire harness 20 is located on one side of the baffle 53, the second part 22 is located on the other side of the baffle 53, the first limiting piece 61 is sleeved on the first wire harness 20 and abuts against the baffle 53. When the spring wire harness 221 of the second part 22 is stretched, the pulling force is transmitted to the first limiting piece 61 through the first wire harness 20, and then directly transmitted to the baffle 53 by the first limiting piece 61, most of the pulling force is offset at the baffle 53, and will not continue to be transmitted to pull the electrical connection point of the first part 21 and the key structure 10, thereby ensuring the connection reliability of the first wire harness 20 and the key structure 10.

[0039] In some embodiments, the refrigerator unlocking device further comprises a second limiting piece 62, which is arranged at the connection between the third part 23 and the second part 22, and is used for limiting one end of the third part 23 close to the second part 22.

[0040] In this way, one end of the third part 23 is connected with the controller 30, and the other end is limited by the second limiting piece 62, so that the third part 23 is limited between the controller 30 and the second limiting piece 62, reducing the risk of the third part 23 being separated from the key structure 10 due to pulling.

[0041] In some embodiments, the refrigerator unlocking device further comprises a second limiting piece 62, which is arranged at the connection between the third part 23 and the second part 22, and is used for limiting one end of the third part 23 close to the second part 22.

[0042] In the embodiment as shown, the refrigerator unlocking device is applied to the vehicle-mounted refrigerator, the vehicle-mounted refrigerator comprises a drawer 72 and a guide rail base 73 located at the bottom wall of the drawer 72, the second limiting member 62 is sleeved on the outer periphery of the third part 23 and abuts against the side of the guide rail base 73, so as to limit the third part 23 between the second limiting member 62 and the controller 30. Similarly, when the spring wire bundle 221 of the second part 22 is stretched, the pulling force is transmitted to the second limiting member 62 and then transmitted to the guide rail base 73 by the second limiting member 62, and most of the pulling force is offset at the guide rail base 73 and cannot continue to be transmitted to pull the electrical connection point between the third part 23 and the controller 30, so as to ensure the connection reliability of the first wire bundle 20 and the controller 30.

[0043] In some embodiments, the unlocking assembly 40 comprises an actuator 41 and a switch structure 42, the actuator 41 is electrically connected with the controller 30 and is used to unlock the switch structure 42 according to the unlocking instruction. The actuator 41 can be but is not limited to a motor and the like, and the actuator 41 comprises but is not limited to a lock tongue, a buckle and the like. The actuator 41 serves as a controlled driving unit and is responsible for receiving the unlocking signal of the controller 30 and converting it into a mechanical action to unlock the switch structure 42.

[0044] It should be noted that the actuator 41 and the switch structure 42 can refer to related technologies, and the present specification does not make specific limitations thereto.

[0045] In the second aspect, based on the same inventive concept, the embodiments of the present application also provide a vehicle-mounted refrigerator, which comprises the refrigerator unlocking device according to any one of the above embodiments or implementation manners.

[0046] In some embodiments, the vehicle-mounted refrigerator further comprises a cabinet 71 and a drawer 72, the drawer 72 is movably arranged in the cabinet 71 along a first direction, and the unlocking assembly 40 is used to lock or unlock the drawer 72 and the cabinet 71. The spring wire bundle 221 is fixedly connected with the drawer 72 and extends along the first direction.

[0047] In other words, the spring wire bundle 221 is directly fixedly connected with the drawer 72 and extends along the movement direction (the first direction) of the drawer 72. When the user pulls out or pushes in the drawer 72, the spring wire bundle 221 will naturally stretch or contract, and its deformation is synchronized with the movement of the drawer 72. In this way, the spring wire bundle 221 itself will not be subjected to additional torsion, bending or transverse pulling force, and it always stretches and contracts along the movement direction of the drawer 72, which is conducive to improving the service life.

[0048] Further, when the refrigerator unlocking device further comprises a wire bundle support 50, the wire bundle support 50 is detachably arranged at the bottom wall of the drawer 72, and the spring wire bundle 221 is accommodated between the wire bundle support 50 and the bottom wall of the drawer 72.

[0049] In this way, the spring wire harness 221 is clamped between the bottom wall of the drawer 72 and the wire harness support 50, which makes the spring wire harness 221 generally invisible to the user, improving the aesthetics of the drawer 72 during the pulling-out process. At the same time, the spring wire harness 221 will not interfere with the surrounding structure, burn, etc., improving the service life of the spring wire harness 221.

[0050] In some embodiments, the vehicle-mounted refrigerator further comprises a front panel 74 connected with the drawer 72, and the key structure 10 is embedded in the front panel 74. By embedding the key structure 10 in the front panel 74, the user can easily identify and press, simplifying the user's operation process. Specifically, the key structure 10 is embedded in the upper part of the front panel 74 to further facilitate user pressing.

[0051] In some embodiments, the front panel 74 comprises a decorative plate 741 and a skeleton 742, and the decorative plate 741 is located outside the skeleton 742 to shield the skeleton 742, playing an aesthetic role. The skeleton 742 is provided with a groove 7421 extending along the height direction of the skeleton 742, and the first part 21 of the first wire harness 20 is located in the groove 7421.

[0052] In this way, the groove 7421 provides a protective channel for the first part 21 of the first wire harness 20, protecting it from being squeezed and isolated from the external environment, which is conducive to aesthetics while avoiding being disturbed by impurities. At the same time, since the spring wire harness 221 of the second part 22 is arranged at the bottom of the drawer 72, the groove 7421 extends along the height direction of the skeleton 742, providing a path for the first part 21 to go, making the connection of the first part 21 and the second part 22 more convenient and natural.

[0053] In some embodiments, the cable support has an edge portion 54 on both sides, the edge portion 54 is provided with a gap 55, and the bottom of the drawer 72 is provided with a first buckle 721. The cable support has a first position and a second position. In the first position, the cable support is attached to the bottom of the drawer 72, and the first buckle 721 is located at the gap 55. In the second position, the cable support is attached to the bottom of the drawer 72, and the edge portion 54 is inserted into the first buckle 721. The cable support is switched between the first position and the second position by moving along its length direction.

[0054] In other words, in the first position, the first buckle 721 of the drawer 72 bottom is opposite and located at the notch 55 of the cable support edge portion 54. Therefore, the buckle and the notch 55 are in alignment, the locking function of the buckle is not triggered, and the cable support can be freely removed through the notch 55. In the second position, by sliding the cable support along its length direction, the solid portion of the edge portion 54 is inserted into or below the first buckle 721. The first buckle 721 clamps the edge portion 54, thereby locking the cable support on the drawer 72 bottom. The assembly worker or maintenance personnel only needs to lower the cable support with the notch 55 aligned with the buckle (first position), and then push it gently (slide to the second position) to complete the fastening, thereby improving the assembly efficiency and maintenance convenience.

[0055] Further, the bottom of the framework 742 is provided with a socket 7422, and the rear of the drawer 72 is provided with a second buckle. In the first position, the cable support is separated from the socket 7422 and the second buckle, and in the second position, one end of the cable support along its length direction is inserted into the socket 7422 of the framework 742, and the other end of the cable support along its length direction extends upward and is clamped and matched with the second buckle of the drawer 72.

[0056] In this way, one end of the cable support is inserted into the socket 7422 of the framework 742 of the front panel 74, and is fixed while facilitating the wiring of the first cable. The other end of the cable support is fixed by the second buckle of the drawer 72, so that both ends of the cable support are fixed, thereby improving the stability of the installation. Moreover, this fixing mode is compatible with the fixing mode of the first buckle 721 described above. When the cable support is slid along the length direction and locked into the first buckle 721 of the drawer 72 bottom, one end (close to the end of the front panel 74) of the cable support is inserted into the socket 7422 of the bottom of the framework 742 of the front panel 74, and the other end also forms a clamping and matching with the second buckle arranged at the rear of the drawer 72. The entire assembly process is very ingenious and simple.

[0057] In a third aspect, based on the same inventive concept, the embodiments of the present application also provide a vehicle, which comprises the vehicle-mounted refrigerator described in any of the above embodiments or implementation manners. The vehicle can be a sedan, a truck, a van, a sport utility vehicle, or any other type of vehicle. In one embodiment, the vehicle is a high-voltage traction battery electric vehicle, a hybrid electric vehicle, or a plug-in hybrid electric vehicle. In another embodiment, the vehicle is an autonomous vehicle, wherein the motor function of the vehicle is controlled without direct input from a human driver.

[0058] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
