[0036] In the related art, a refrigerator in a vehicle is usually arranged at the vehicle's passenger-side instrument panel, between the two front seats. Due to the structural requirements of the refrigerator itself, its structural stiffness is relatively large. When it is arranged at the vehicle's passenger-side instrument panel, when the vehicle brakes suddenly, the passengers in the back row will fall forward, and thus it is possible that their heads will hit the refrigerator, causing injury to the passengers in the back row and failing to meet the requirements of the rear passenger interior head impact regulation test. To solve this problem, this application particularly provides a vehicle-mounted refrigerator.

[0037] Figure 1 Shows the assembly when a vehicle-mounted refrigerator according to some embodiments is installed in a vehicle Figure 1 . Figure 2 Shows the assembly when a vehicle-mounted refrigerator according to some embodiments is installed in a vehicle Figure 2 . Figure 3 Shows a schematic structural diagram of a vehicle-mounted refrigerator according to some embodiments.

[0038] Refer to Figures 1 to 3 , a vehicle-mounted refrigerator 1, for installation in a vehicle, may include a housing 11. The housing 11 is configured as the outer shell structure of the vehicle-mounted refrigerator 1 for accommodating other related components of the vehicle-mounted refrigerator 1.

[0039] In some embodiments, the interior of the housing 11 is hollow, and a cavity is formed inside the housing 11, and the cavity provides an accommodation space. Among them, the housing 11 may be integrally in a rectangular columnar structure, so that the vehicle-mounted refrigerator 1 is integrally in a rectangular columnar structure, or the housing 11 may also be in a cylindrical structure, so that the vehicle-mounted refrigerator 1 is integrally in a cylindrical structure.

[0040] In some embodiments, the vehicle-mounted refrigerator 1 may include an inner liner 12. The inner liner 12 is arranged in the cavity, and the interior of the inner liner 12 is hollow to form a refrigeration cavity, and the items to be refrigerated are placed in the refrigeration cavity for low-temperature storage.

[0041] In some embodiments, there may be a gap between the inner container 12 and the inner wall of the housing 11, and a foaming layer 13 is formed between the inner container 12 and the inner wall of the housing 11. By forming the foaming layer 13, the inner container 12 is isolated from the outside world, improving the heat preservation effect of the refrigeration chamber inside the inner container 12. Among them, the foaming layer 13 is formed by injecting foaming material into the gap between the inner container 12 and the housing 11 through a foaming material injection device such as a foaming gun when manufacturing the vehicle-mounted refrigerator 1. The foaming layer 13 may be made of polyurethane resin material, having certain elasticity and heat preservation properties.

[0042] In some embodiments, the inner container 12 may be adapted to the shape of the housing 11. For example, if the housing 11 has a rectangular columnar structure, the inner container 12 also has an overall rectangular columnar structure.

[0043] In some embodiments, the vehicle-mounted refrigerator 1 may further include a refrigeration system. The refrigeration system may include a compressor, an evaporator and a condenser. The refrigeration system may be disposed in a compressor compartment provided at the inner bottom of the housing 11, making the vehicle-mounted refrigerator 1 a compressor-type refrigerator, which has the advantage of good refrigeration effect. The specific refrigeration principle will not be elaborated here.

[0044] In some embodiments, the refrigeration system may further include a semiconductor chip, which uses the Peltier effect of the semiconductor chip for refrigeration, having the advantages of compact structure and low cost. The specific refrigeration principle will not be elaborated here.

[0045] In some embodiments, the vehicle-mounted refrigerator 1 may be fixed in the vehicle. Specifically, the vehicle-mounted refrigerator 1 may be disposed at the passenger's instrument panel of the vehicle, between the two front seats 2, which is convenient for both the front-row passengers and the rear-row passengers to use.

[0046] In some embodiments, the vehicle-mounted refrigerator 1 may include two fixing parts 15. The two fixing parts 15 are respectively connected to opposite sides of the bottom of the housing 11. The fixing parts 15 may be strip-shaped and extend along the length direction of the housing 11. Fixing holes may be provided on the fixing parts 15. When the vehicle-mounted refrigerator 1 is installed in the vehicle, the vehicle-mounted refrigerator 1 may be fixedly connected to the vehicle chassis through the fixing holes to fix the vehicle-mounted refrigerator 1 on the vehicle chassis.

[0047] In some embodiments, the upper part of the housing 11 may partially protrude towards the rear side of the vehicle, so that there is a larger distance between the lower part of the housing 11 and the rear seat 2, providing a larger foot space for the rear-row passengers. And the upper part of the housing 11 protruding towards the rear side can increase the volume of the refrigeration chamber inside the vehicle-mounted refrigerator 1, allowing more items to be loaded.

[0048] Figure 4 Shows Figure 3 The partial enlarged view at A in Figure 5 Exemplarily shows a top view of a vehicle-mounted refrigerator according to some embodiments. Figure 6Exemplarily shown Figure 5 A cross-sectional view taken along the B-B direction in

[0049] Continuing to refer to Figures 4 to 6 , in some embodiments, in order to place the in-vehicle refrigerator 1 in the vehicle, especially when placed at the passenger dashboard, to meet the requirements of the convex head regulation in a passenger vehicle and reduce the injury suffered by a passenger when colliding with the in-vehicle refrigerator 1 during an emergency brake of the vehicle, on the height direction of the refrigerator, the outer sidewall of the housing 11 includes a plurality of first crush grooves 111 arranged at intervals. By arranging a plurality of crush grooves in the height direction of the refrigerator, it is guided that the refrigerator housing 11 has a certain degree of crush deformation tendency along the height direction of the refrigerator when being impacted, and the longitudinal stiffness of the refrigerator is reduced by using the formed crush grooves, and the energy absorption capacity of the refrigerator housing 11 is increased, thereby improving the buffer energy absorption effect of the refrigerator housing 11.

[0050] In some embodiments, the number of the first crush grooves 111 is set to be plural, which can increase the buffer energy absorption effect of the housing 11. At the same time, the groove depth of the first crush grooves 111 can be set deeper on the premise of meeting the structural strength of the housing 11.

[0051] In some embodiments, the plurality of first crush grooves 111 can be adjacent to each other in sequence along the height direction of the refrigerator, or can be arranged at intervals.

[0052] In some embodiments, on the height direction of the refrigerator, the outer sidewall of the housing 11 may include a plurality of first crush ribs 116 arranged at intervals. Any two adjacent first crush ribs 116 are connected by a first connecting rib 117, and the first connecting rib 117 is recessed into the cavity relative to the first crush rib 116, so that any two adjacent first crush ribs 116 and the first connecting rib 117 therebetween enclose to form the above-mentioned first crush groove 111. In this way, when a collision occurs, since the space between the two first crush ribs 116 is the first crush groove 111, the first crush ribs 116 can collapse into the first crush groove 111 along the height direction of the refrigerator, thereby orderly reducing the longitudinal stiffness of the housing 11. Referring to the design concept of the energy absorption box for a vehicle frontal collision, the energy absorption capacity of the housing 11 is increased, the peak value of the acceleration of the head during the passenger collision is reduced, so as to meet the requirements of the convex head collision regulation in a passenger vehicle, and the harm degree suffered by the passenger is reduced.

[0053] In some embodiments, the first crush rib 116 and the first connecting rib 117 can be integrally formed, which can improve the integrity of the housing 11, improve the structural strength of the housing 11 itself, and also facilitate simplifying the manufacturing process.

[0054] In some embodiments, when forming the first crushing groove 111, the housing 11 can be formed first so that the outer sidewall of the housing 11 is planar, and then the outer sidewall of the housing 11 is partially recessed into the cavity at intervals. The recessed part of the outer sidewall of the housing 11 forms the first connecting rib 117, and the non-recessed part of the housing 11 forms the first crushing rib 116.

[0055] Figure 7 An exemplary cross-sectional view of the housing in a vehicle-mounted refrigerator according to some embodiments is shown.

[0056] Continue to refer to Figure 7 , in some embodiments, an arc transition can be made between the first connecting rib 117 and the first crushing rib 116 so that the first crushing groove 111 can be an arc-shaped groove, so that when the first crushing rib 116 collapses towards the first crushing groove 111, it can collapse faster and the corresponding buffering effect of the arc-shaped groove is better.

[0057] In some embodiments, the longitudinal section of the first connecting rib 117 can be semi-circular, or can be an arc corresponding to other central angles, such as an arc corresponding to a 90-degree central angle.

[0058] In some embodiments, the longitudinal section of the first connecting rib 117 can be wavy. The wavy first connecting rib 117 folds more in the longitudinal direction of the vehicle-mounted refrigerator 1, and the buffering and energy absorption effect is also better.

[0059] In some embodiments, the housing 11 can include a bottom plate 112. The bottom plate 112 is in a flat plate shape and can be supported on the internal chassis of the vehicle to support the housing 11.

[0060] In some embodiments, the housing 11 can include sidewalls 113. The sidewalls 113 are connected to the edges of the bottom plate 112, and the sidewalls 113 extend upward to protrude from the bottom plate 112. The sidewalls 113 and the bottom plate 112 enclose a cavity, and the first crushing rib 116 and the first connecting rib 117 are formed on the sidewalls 113.

[0061] Among them, the top end of the sidewall 113 is provided with the first crushing rib 116. In this way, at least during a collision, the first crushing rib 116 at the top end of the sidewall 113 collapses first to buffer and absorb energy as soon as possible, thereby protecting the passengers. Further, the bottom end of the sidewall 113 is also provided with the first crushing rib 116, so that the first crushing rib 116 is arranged from the top end to the bottom end of the sidewall 113, so as to maximize the energy absorption capacity of the sidewall 113 by being covered with the first crushing rib 116.

[0062] In some embodiments, the side enclosure 113 may include two oppositely disposed first side plates 114 and two oppositely disposed second side plates 115. The two first side plates 114 and the two second side plates 115 are sequentially connected to enclose the side enclosure 113, making the side enclosure 113 as a whole in a rectangular columnar structure. When connecting, the first side plate 114 is connected to the adjacent second side plate 115, and the bottoms of the first side plate 114 and the second side plate 115 are both connected to the corresponding edges of the bottom plate 112. In some embodiments, the first side plate 114, the second side plate 115, and the bottom plate 112 may be integrally formed.

[0063] In some embodiments, first crush ribs 116 and first connecting ribs 117 may be provided on both the first side plate 114 and the second side plate 115 in the side enclosure 113, so that first crush grooves 111 are formed on both the first side plate 114 and the second side plate 115, thereby enabling the outer side walls of the housing 11 in different directions to have a certain degree of crush deformation tendency during a collision, and improving the overall buffer energy absorption effect of the housing 11.

[0064] In some embodiments, the first crush ribs 116 and the first connecting ribs 117 may also be partially not provided in the side enclosure 113. For example, when the vehicle-mounted refrigerator 1 is disposed at the vehicle's passenger-side instrument panel, the part of the side enclosure 113 facing away from the rear passengers may not be provided with the first crush ribs 116 and the first connecting ribs 117, while the parts of the side enclosure 113 facing the rear passengers and connected to the seat 2 are both provided with the first crush ribs 116 and the first connecting ribs 117, so as to perform crush energy absorption during a collision and protect the rear passengers.

[0065] In some embodiments, the first crush grooves 111 formed on the first side plate 114 and the first crush grooves 111 formed on the second side plate 115 are at least partially staggered in the height direction of the refrigerator, so as to reduce the longitudinal stiffness of the housing 11 during a collision while ensuring the structural strength of the housing 11. It can be understood that the corresponding first crush ribs 116 on the first side plate 114 and the second side plate 115 are partially at the same height and partially staggered in the height direction of the vehicle-mounted refrigerator 1.

[0066] In some embodiments, both ends of the first crush groove 111 formed on the first side plate 114 extend to the edges of the second side plate 115 on the corresponding side. Both ends of the first crush groove 111 formed on the second side plate 115 extend to the edges of the first side plate 114 on the corresponding side, so that when the first crush rib 116 collapses into the first crush groove 111, it can cause the first side plate 114 and the second side plate 115 to collapse downward as a whole, maximizing the energy absorption part of the side enclosure 113 and maximally increasing the energy absorption of the housing 11.

[0067] In some embodiments, the thickness of the housing 11, i.e., the thickness of the first side plate 114 and the second side plate 115, should not be too thick. If it is too thick, it will be difficult for the buffer to collapse and the buffer effect will be poor. Nor should it be too thin, otherwise the structural strength of the housing 11 itself will not be sufficient. In this embodiment, the housing 11 can be made of a galvanized sheet with a thickness of 0.6 mm to achieve a balance between strength and buffer effect.

[0068] Figure 8 An exemplary cross-sectional view of the foaming layer in a vehicle-mounted refrigerator according to some embodiments is shown.

[0069] Continue to refer to Figure 8 , in some embodiments, a plurality of second crush grooves 131 may be recessed on the outer sidewall of the foaming layer 13, and the second crush grooves 131 correspond to the first connecting ribs 117 one by one. When forming the first connecting ribs 117, the outer sidewall of the foaming layer 13 can be simultaneously recessed inward to form the second crush grooves 131, and the shapes of the second crush grooves 131 and the first connecting ribs 117 are adapted to each other, so that the foaming layer 13 with the second crush grooves 131 improves its buffer energy absorption effect in the height direction of the vehicle-mounted refrigerator 1.

[0070] It can be understood that the part of the outer sidewall of the foaming layer 13 corresponding to the first crush rib 116 protrudes outward compared with the second crush groove 131, and its shape is adapted to that of the first crush rib 116.

[0071] In some embodiments, along the height direction of the vehicle-mounted refrigerator 1, the outer sidewall of the inner liner 12 may include a plurality of second crush ribs arranged at intervals, and any two adjacent second crush ribs are connected by a second connecting rib, and the second connecting rib is recessed into the refrigeration cavity relative to the second crush rib. By forming the second crush ribs and the second connecting ribs on the inner liner 12 as well, a crush groove is also formed between the second crush ribs and the second connecting ribs, so as to cooperate with the housing 11 to jointly reduce the longitudinal stiffness of the vehicle-mounted refrigerator 1 during a collision.

[0072] It can be understood that the second crush ribs and the second connecting ribs can be integrally formed. The shape and structure of the second crush ribs and the second connecting ribs can be set with reference to the first crush rib 116 and the first connecting rib 117.

[0073] In this embodiment, the vehicle-mounted refrigerator 1 may further include a door body 14. The door body 14 is disposed at the top of the side wall 113 in an openable and closable manner to open or close the cavity. By providing the door body 14 at the top of the side wall 113, it is convenient for both the front-row passengers and the rear-row passengers to take the items in the vehicle-mounted refrigerator 1 at the same time. At the same time, setting the door body 14 at the top of the side wall 113 does not affect the arrangement of the first crush rib 116 on the side wall 113.

[0074] In some embodiments, the first crush rib 116 located at the top of the side wall 113 can be connected to the door body 14. Thus, when the door body 14 is impacted, the energy will be first transferred to the first crush rib 116 at the top, and the multi-stage first crush ribs 116 provided subsequently will gradually absorb energy and buffer the impact.

[0075] In some embodiments, the door body 14 can be rotatably connected to the top of the side wall 113 to open or close the cavity. One end of the door body 14 can be rotatably connected to the first side plate 114 or the second side plate 115. When it rotates to the horizontal plane, it just covers the top opening of the cavity, thereby closing the cavity.

[0076] In some embodiments, the door body 14 can also be slidably arranged along the horizontal direction at the top of the side wall 113. By translating the door body 14, the cavity can be exposed or closed.

[0077] In summary, in this embodiment, by providing the first crush rib 116 and the first connecting rib 117 on the housing 11, and cooperating with the second crush groove 131 provided on the foaming layer 13, it is possible to jointly guide the housing 11 of the vehicle-mounted refrigerator 1 to have a certain degree of crush deformation trend along the height direction of the vehicle-mounted refrigerator 1 when being impacted, so as to buffer and absorb energy, reduce the peak acceleration of the passenger's head collision, slow down the impact on the passenger, enable the vehicle-mounted refrigerator 1 to meet the requirements of the convex head collision regulation for passenger cars, and protect the safety of the passengers.
