Description

Title of the invention: Vehicle for transporting an air-conditioned container

[0001] The invention relates to a vehicle capable of transporting at least one container whose temperature inside said container can be modified, an assembly comprising such a vehicle and a container, as well as a container adapted to be transported by such a vehicle. The invention also relates to a method for loading a container into the vehicle.

[0002] Some vehicles include a cargo area in which objects such as containers can be temporarily placed. The cargo area is delimited by a floor and a roof (or roof panel), and optionally by two side walls, right and left. It will be understood that this type of cargo area can be located in a trunk, a cargo box, a trailer, or within the cargo space of a commercial vehicle.

[0003] Container immobilization within the loading area can be ensured by a strap immobilization device. A clamping device comprising rigid, vertically movable plates that press against at least one container to attempt to immobilize it within the loading area was also proposed in document FR2344420.

[0004] Furthermore, it may be necessary to maintain a specific temperature, for example, a cold temperature, for products stored in containers loaded in the loading area. For example, in the case of perishable foodstuffs, it is advantageous to be able to maintain the temperature inside the containers between 2°C and 6°C. For this purpose, a vehicle with a flatbed loading area, on which a container is mounted, has been proposed, for example, in document CN216184735. The container has an opening positioned opposite a ventilation vent located on the flatbed to supply air at a specific temperature to ventilate or cool the container's interior. The container is placed vertically on the flatbed, its position defined by centering pins.

[0005] The drawback of this solution is that it requires vertical loading of the container onto the platform, necessitating a loading area without a roof, and cannot be applied to a mobile container with wheels allowing it to be moved on the ground. Indeed, for such a container with wheels, only the wheels need to be in contact with the ground and the floor of a vehicle to allow its movement: it is not possible to ensure a connection with the ventilation opening. without leakage. Another disadvantage is that the container must have a precise and fixed dimension, and it is not possible to install a container of a different size.

[0006] The objective of the invention is to overcome these drawbacks. In particular, one of the aims of the invention is to provide a vehicle comprising a loading area suitable for receiving wheeled containers and means for connecting a connection system to an air conditioning system enabling the temperature inside the container to be modified.

[0007] This goal is achieved according to the invention, thanks to a vehicle comprising a loading platform suitable for receiving a container, a device for heating a heat transfer fluid, a device for distributing the heat transfer fluid, comprising at least one fluid distribution line from the heating device, connected to said heating device, to a connection fitting intended to be connected to a fitting located on a container loaded onto the platform, notable in that the connection fitting is movable between a connection position and a free position, and the vehicle comprises a means for moving the fitting between the connection position and the free position.

[0008] Advantageously, it is possible to load a container with wheels by rolling it onto the loading platform, thus ensuring contact with the ground and the platform only via the wheels, without being hindered by the freely positioned nozzle. This also allows the container to be supplied with heat transfer fluid to regulate its temperature by moving the nozzle to the connection position once the container is positioned on the platform. Another advantage is that it is possible to load containers of different sizes while still maintaining the ability to connect them to the heat transfer fluid distribution system using the movable nozzle.

[0009] In a particular embodiment of the invention, the heat transfer fluid is air. Preferably, the temperature control device is an air conditioning system.

[0010] Advantageously, the device can thus use ambient air. Furthermore, in the event of a leak due to a failure of the dispensing device or a poor connection between the nozzle and the container, there is no risk of pollution or danger to the user. In particular, if the loading tray is in a closed enclosure, in the event of a leak, only air will be diffused into said enclosure. Moreover, this eliminates the need for a shut-off valve at the nozzle to prevent leaks when the nozzle is not in the connected position.

[0011] In another embodiment of the invention, the distribution device comprises a pair of pipes intended to be connected to a container loaded onto the platform, the pair of pipes comprising a supply pipe and a return of the heat transfer fluid, each pipe having a movable supply nozzle, respectively a supply nozzle and a return nozzle.

[0012] Advantageously, efficient circulation of the heat transfer fluid in the container connected to the circulation device is achieved when each of the fittings is connected to said container, the fluid being sent into the container via the supply line and the supply fitting and exiting the container via the return fitting and the return line. Another advantage is that the heat transfer fluid can be recycled and then returned to the container, thus saving energy by reducing the need to maintain it at a given temperature.

[0013] In another embodiment, the vehicle includes a means for retaining a container loaded on the platform, said retaining means comprising a vertically movable support face between a non-locking position and a locking position in which the support face presses on a container arranged under said face, said support face being arranged opposite and at a distance from the platform, the vehicle further comprising a linking means between the retaining means and the connection tip so that the connection tip moves from the free position to the connection position when the support face moves from the non-locking position to the locking position.

[0014] Advantageously, therefore, it is not necessary to install a specific motorized device to move the connection tip, as the tip is moved by moving the locking means. It will be understood that the bearing face in the free position is located higher vertically than in the locked position.

[0015] In a preferred embodiment of the invention, the holding means comprises a movable plate at least along a vertical axis, arranged substantially parallel to the loading platform, opposite the loading surface and at a distance from it, and whose face turned towards said platform comprises the support face.

[0016] In a preferred embodiment of the invention, the tip is fixed to the plate so as to move with said plate between the free position and the connection position.

[0017] Thus advantageously, implementation is simplified because it is not necessary to create a specific device to move the nozzle, the movement of the nozzle being achieved by the movement of the plate.

[0018] The invention also relates to an assembly comprising a vehicle as described above and a container mounted on the vehicle's loading platform, the container having a connection fitting connected to the nozzle when said nozzle is in the connection position so as to allow a transfer of the heat transfer fluid into the container.

[0019] In a particular embodiment of the assembly, the nozzle is connected to the fitting when the bearing face is in contact with the container.

[0020] The invention also relates to a container comprising side walls, a lower wall and an upper wall forming between them a closed enclosure, wheels fixed to the lower wall so as to allow movement of the container on a surface, the upper wall being opposite the lower wall, remarkable in that it further comprises a circulation circuit of a heat transfer fluid so as to obtain a given temperature in the enclosure, a supply fitting disposed on the upper wall and suitable to be connected to a circulation circuit so as to allow the circulation circuit to be supplied with heat transfer fluid by said fitting when it is installed on a vehicle as described above.

[0021] The invention also relates to a method of loading a container into a vehicle as described above, comprising a step of loading the container onto the platform, a step of blocking the container by a holding means, a step of moving the nozzle from the free position to the connection position, so as to connect to the container fitting, a step of circulating the heat transfer fluid from the heating device to the container.

[0022] The invention will be better understood upon reading the following description, given solely by way of example and made with reference to the accompanying drawings, in which:

[0023] [Fig-1] represents a vehicle according to the invention in side view, showing the interior said vehicle at the level of a loading platform.

[0024] [Fig.2] represents a rear view of the vehicle in [Fig.1].

[0025] [Fig.3] is an enlarged view of [Fig.1] at the level of a container and its means maintenance.

[0026] [Fig.4] is a view of a fitting of a container according to the invention.

[0027] The drawings are schematic representations to facilitate understanding of the invention. The components are not necessarily shown to scale. The same reference numerals correspond to the same components from one figure to another.

[0028] The X-axis represents the longitudinal direction of the vehicle, the Y-axis the transverse direction, and the Z-axis the vertical direction. The forward, backward, up, and down directions are taken in the vehicle's frame of reference.

[0029] Figures 1 and 2 illustrate a vehicle 1 in a variant of the invention, comprising a loading platform 100 disposed behind a cab 101. The cab 101 is, for example, a passenger compartment of the vehicle 1 housing a driver of the vehicle 1. The loading platform 100 is disposed in a cargo space and forms a floor of said cargo space. The vehicle 1 has a roof 102, also known as the roof panel, disposed above the loading platform 100. The vehicle also has side walls 103 and 104, between the platform 100 and the roof 102. The cargo space is defined by these side walls 103, 104, the platform 100, and the roof 102. It can be closed by a rear wall 105 at the rear of the Vehicle 1. Access doors to the loading area are provided on one of the walls 102, 103, 104, or 105. The loading platform 100 and the loading area are arranged to accommodate containers 10. In Figures 1 and 2, several containers 10 are loaded onto the platform 100. The container 10 has side walls 12, a bottom wall, and a top wall 14 forming an enclosed space 13, and wheels 11 fixed to the bottom wall to allow the container 10 to be moved over a surface, with the top wall 14 opposite the bottom wall.

[0030] The vehicle 1 includes a device for heating a heat transfer fluid 5 and a device for distributing said heat transfer fluid 4. The distribution device 4 includes at least one distribution line 41a, 41b for the heat transfer fluid from the heating device 5 to a connection fitting 42a, 42b. The distribution line 41a, 41b is therefore connected to said heating device 5. The fitting 42a, 42b is intended to be connected to a fitting 15a, 15b located on the container 10 loaded onto the platform 100. The fitting 42a, 42b is movable between a connected position and a free position. The vehicle 1 includes a means 3 for moving the fitting 42a, 42b between the connected position and the free position.

[0031] When a container 10 is loaded onto the platform 100, i.e. moved to be placed on the platform 100, and the fitting 42a, 42b is in the connection position, said fitting 42a, 42b is connected to the fitting 15a, 15b so as to allow a passage of heat transfer fluid between the pipe 41a, 41b and the container 10. In other words, the heat transfer fluid moves between the pipe 41a, 41b and the container 10 by passing through the fitting 42a, 42b and the fitting 15a, 15b when the fitting 42a, 42b is connected to the fitting 15a, 15b. The temperature in enclosure 13 of the container can thus be regulated: for example, for perishable products, it can be kept at a cool temperature between 2°C and 6°C, or on the contrary, it can be chosen to be hot to keep prepared dishes warm.The connection between fitting 42a, 42b and fitting 15a, 15b is, for example, sealed to prevent leakage of the heat transfer fluid during its passage between fitting 42a, 42b and fitting 15a, 15b.

[0032] The fluid heating device 5 includes a means for circulating the fluid, not shown, towards the nozzle 42a, 42b, so as to circulate the fluid in the conduit 41a, 41b and thus supply the container with heat transfer fluid when the nozzle 42a, 42b is connected to the fitting 15a, 15b.

[0033] In the embodiment illustrated in the figures, the heat transfer fluid is air. The temperature-setting device 5 is, for example, an air conditioning system, such as a heat pump, and the means for circulating the fluid is a turbine. Alternatively, the air conditioning system may be a common air conditioning device with that of the vehicle cabin air conditioning 1. Alternatively, the heat transfer fluid may be a fluid other than air.

[0034] In the embodiment illustrated in the figures, the distribution device 4 comprises a pair of pipes 41a and 41b intended to be connected to the container loaded onto the platform 100. One of the pipes is a supply line 41a and the other a return line 41b for the heat transfer fluid. Each pipe 41a, 41b has a movable supply fitting 42a, 42b. The supply line 41a thus has a supply fitting 42a and the return line 41b has a return fitting 42b. The container 10 has two fittings 15a and 15b: a supply fitting 15a and a return fitting 15b. When the supply fittings 42a and return fittings 42b are in the connection position, they are connected respectively to the supply fittings 15a and return fittings 15b of the container 10.The connections of the supply fitting 42a to the supply fitting 15a and of the return fitting 42b to the return fitting 15b are, for example, sealed to prevent leaks of the heat transfer fluid.

[0035] The supply line 41a guides the heat transfer fluid, for example air, from the heat transfer fluid heating device 5 to the supply nozzle 42a, following arrow Fa, and thus supplies the container 10 via the connection between the supply nozzle 42a and the supply fitting 15a, when the supply nozzle 42a is in the connected position. Once the fluid has circulated in the container 10, it returns to the heating device 5 guided by the return line 41b, via the connection between the return nozzle 42b and the return fitting 15b.

[0036] Before loading a container 10 into the vehicle 1, the nozzles 42a, 42b are in a free position, in order to allow the container 10 to be moved onto the platform 100 and loaded onto said platform 100. Once the container 10 is correctly positioned on the platform 100, the nozzle(s) 42a, 42b are moved into their connection position so as to connect to the fitting(s) 15a, 15b of the container 10.

[0037] Some or all of the fittings 42a, 42b may have valves for closing said fitting(s) 42a, 42b and blocking the flow of the heat transfer fluid. For example, the valve(s) close the flow of the heat transfer fluid when the fitting(s) 42a, 42b are not in the connection position. This eliminates the risk of the heat transfer fluid escaping from the fitting(s) 42a, 42b when said fitting(s) 42a, 42b are not in the connection position.

[0038] In the embodiment shown in the figures, the vehicle 10 carries several containers 10. The distribution device 4 comprises several pipes 41a, 41b, for example several pairs of pipes 41a, 41b, each pair of pipes comprising a supply line 41a and a return line 41, with respectively a supply nozzle 42a and a return nozzle 42b, for supplying each of the containers 10 separately using each pair of lines 41a, 41b.

[0039] In order to ensure that the container(s) are correctly positioned on the platform 100, positioning means may be provided, for example at the level of the platform 100, such as rails 6 as illustrated in [Fig.2], and / or positioning wedges not shown.

[0040] To hold a container 10 in position once loaded onto the platform 100, the vehicle 1 includes a holding means 3. Said holding means 3 includes a support face 31 movable at least along a vertical axis between a non-locking position and a locking position. The support face 31 is positioned opposite and at a distance from the platform 100, so as to allow the installation of a container between the platform 100 and the support face 31. In the non-blocking position, the support face 31 is positioned at a height greater than the height of the container 10, relative to the platform 100, so as to allow the container 10 to pass between said support face 31 and the platform 100. In other words, in the non-blocking position, the support face 31 is sufficiently far from the platform 100 to allow the container 10 to pass between it and the platform 100 by rolling the container 10 on its wheels 6.

[0041] In the locked position, the support face 31 presses against the container 10 located beneath said support face 31, against the upper wall 14 of the container 10, and exerts pressure. This pressure holds the container in the vertical direction Z, longitudinal direction X, and transverse direction Y relative to the vehicle 1. In other words, to move from the free position to the locked position, the support face 31 moves vertically downwards towards the loading platform 100.

[0042] In order to allow the movement of the end piece(s) 42a, 42b simultaneously with the movement of the bearing face 31, the end piece(s) 42a, 42b are connected to the retaining means 3 by a linkage such that the connecting end piece(s) 42a, 42b move from the free position to the connected position when the bearing face 31 moves from the unblocked position to the blocked position. For example, the linkage may be a articulated connecting rod or a rigid connection.

[0043] In the embodiment shown in the figures, the retaining means 3 comprises a vertically movable plate 32, arranged substantially parallel to the loading platform 100, opposite and at a distance from the loading platform 100, and whose face facing said platform 100 comprises the support face 31, and a deployment system vertically displacing the plate 32. The plate 32 is fixed to the roof of the vehicle 100, or alternatively to a structural element of the vehicle 100 located above the container loaded onto the platform 100, via the system of Deployment 3. In the figures, the deployment system is a scissor-type mechanism that extends and retracts via an actuator (not shown). The actuator could be, for example, a worm gear connected to an electric motor or a hydraulic cylinder. Alternatively, the deployment system could be a cylinder or an inflatable bladder directly moving plate 32.

[0044] In another variant, the platform 32 includes a centering means cooperating with the container 10, so that when the platform 32 descends towards the container 10, the centering means ensures precise positioning of the container 10. For example, the platform 32 includes a conical element projecting from the support face 31 and fitting into a hollow shape of complementary shape disposed on the container 10.

[0045] Figure 3 illustrates another variant in which the centering means is achieved by dropped edges 33 arranged along opposite sides of the support face 31, oriented downwards and forming an open angle with the support face 31, so as to slide on the edges of the upper wall 14 of the container 10 and to center the container 10 during the descent of the platform 32 until the support face 31 is brought against the upper wall 14. Thus, the container 10, and more particularly its upper wall 14, is positioned precisely relative to the retaining means 3. By allowing precise positioning of the container 10, the connection of the end fitting(s) 42a, 42b to the fitting(s) 15a, 15b during their movement from the free position to the connection position is ensured without the need for a complex positioning device for the end fitting(s) 42a, 42b compared to fittings 15a, 15b.

[0046] In the embodiment shown in the figures, the end pieces 42a, 42b are fixed to the plate 32 so as to move with said plate 32. For example, one or all of the end pieces 42a, 42b pass through the plate 32 and open onto the support face 31. Alternatively, some or all of the end pieces 42a, 42b are fixed to one side of the plate 32, for example, to an edge of said plate 32. In another alternative, the plate 32 has an opening in its center, so as to have a frame shape, through which one or more of the end pieces 42a, 42b, fixed to said plate 32, pass. In these alternatives, the end piece(s) 42a, 42b connect to one or more of the fittings 15a, 15b when the plate 32 rests by its bearing face 31 on the upper wall 14 of the container 10.

[0047] As illustrated in [Fig. 1], the locking of the container 10 and the connection of one or more of the tips 42a, 42b on one or more of the fittings 15a, 15b of the container 10 are possible for containers 10 of different heights, the vertically movable plate 32 adjusting its displacement to the height of the container 10. Thus, the displacement of the tips 42a, 42b adapts to the height of the containers 10.

[0048] In the embodiment shown in the figures, the fitting(s) 15a, 15b are located on the upper wall 14 of the container 10 in order to allow connection with the or the tips 42a, 42b during the movement of said tips 42a, 42b with the movement of plate 32.

[0049] In an alternative not shown, the end piece(s) 42a, 42b are moved by a specific means of movement, independent of the holding means 3.

[0050] In another variant not shown, the fitting(s) 15a, 15b are on a different wall of the container 10 than the upper wall 14, for example on one of the side walls 12.

[0051] The container 10 includes a circulation circuit, not shown, for a heat transfer fluid so as to obtain a given temperature in the enclosure 13. For example, the circulation circuit may be one or more pipes passing through the upper wall 14 from the fitting(s) 15a, 15b, so as to allow the diffusion of the fluid into the enclosure 13, for example when the fluid is air. Alternatively, the circulation circuit is a pipe located within the thickness of one or more of the walls of the container 10, connected on one side to the supply fitting 15a and on the other to the return fitting 15b.

[0052] In another embodiment, a shut-off valve is provided on the fitting(s) 15a, 15b to prevent the heat transfer fluid from escaping the circulation circuit of the container 10, and thus maintain the temperature of the enclosure 13 of the container 10 for a longer period. In one embodiment, the valve opens automatically when the fitting 15a, 15b is connected to the nozzle 42a, 42b.

[0053] Figure 4 illustrates an embodiment of the valve in which said valve comprises a movable closing wall 16 between an open position and a closed position, and a return means 17 returning the closing wall 16 to its closed position. In the closed position, the closing wall 16 obstructs the passage of fluid through the fitting 15a, 15b: the valve is closed. In the open position, the closing wall 16 is moved so as not to obstruct the passage of fluid through the fitting 15a, 15b. For example, as illustrated in Figure 4, the closing wall 16 pivots about an axis, and a spring 17 exerts a force returning the closing wall 16 to the closed position. In the variant shown in Figure 4, the closing wall 16 pivots about an axis, and a spring 17 exerts a force returning the closing wall 16 to the closed position.[4] The closing wall 16 moves from the closed position to the open position pushed by the end piece 42a, 42b when it is connected to the fitting 15a, 15b: the end piece 42a, 42b enters the fitting 15a, 15b, and its tip comes into contact with the closing wall 16 and pushes it towards the open position. The closing wall 16 is, for example, made of an insulating material, such as expanded polystyrene foam.

[0054] In order to allow movement of the connection tip 42a, 42b, the supply line 41a, 41b is, for example, made of a flexible material. For example, it may include an expandable accordion-shaped segment. Alternatively, it may include several rigid segments articulated together. In another variant, the supply conduit 41a, 41b may include a telescopic segment.

[0055] The loading of the container 10 onto the loading platform 100 follows a loading process comprising a step of loading the container (10) onto the platform (100), in which the container 10 is brought onto the loading platform 100 in a given position by rolling it on its wheels 11, a step of blocking the container (10) by the holding means (3), a step of moving the nozzle(s) (42a, 42b) from the free position to the connection position, so as to connect the said nozzle(s) (42a, 42b) onto the fitting(s) (15a, 15b) of the container (10), a step of circulating the heat transfer fluid from the heating device (5) into the container (10) through the device in order to heat the enclosure 13 of the container 10.

[0056] In an embodiment of the method, the locking step of the container 10 is obtained by moving the bearing face 31 from the non-locking position to the locking position in which said face 31 is in contact with the container 10, for example against the upper wall 14 of the container 10, so as to block any movement of said container 10, the movement of the bearing face 31 generating the movement of the end piece(s) 42a, 42b from the free position to the connection position.

[0057] Figures 1 and 2 represent a so-called motor vehicle, that is to say, one comprising means of propulsion enabling it to move and a driver. Alternatively, the vehicle may be a trailer, or even an autonomous motor vehicle, that is to say, one not requiring a driver, or even a railway wagon.
