Description

Box and lid assembly in the vehicle's center console

Field of technology

The present invention relates to elements for ventilation and heat removal from boxes for wireless charging of portable electronic devices, especially in vehicles.

Current state of the art

In the current state of the art, box lids are used for wireless charging of portable electronic devices (e.g. mobile phones, tablets, etc.) indoors. During wireless inductive charging, the temperature of the entire storage area increases in closed boxes, which often leads to a safety shutdown of the portable electronic device due to exceeding its operating temperature.

Korean patent application KR 20160028764 A describes a device for storing and wirelessly charging portable electronic devices in a vehicle. This device includes a box with a storage space, e.g. in the shape of a vertical slot, an ultraviolet radiation source and a wireless charging unit located in the box, an anti-shock element at the bottom of the box, and an inwardly hinged lid with a stop to fix the position of the portable electronic device. There is also a light indicator, an information panel and a charging port around the box. In one embodiment, the portable electronic device is placed in the storage space vertically with one end overhanging the edge of the box, with the lid only partially flipped inward and a stop on this lid fixing the position of the portable electronic device. This can create space for partial ventilation of the storage space, but the disadvantage remains that the portable electronic device protrudes above the edge of the box and is thus exposed to the risk of mechanical damage.

The device for storage and wireless charging of portable electronic devices described in the international patent application WO 2016047862 A1 also works on a similar principle.

In US patent application US 2016344221 A1, a device for storage and wireless charging of portable electronic devices in a vehicle is also described. This device includes several spatially separated containers that can be closed with hinged or sliding lids. A wireless charging unit for a portable electronic device is arranged in one box, while the storage space for charging is provided with a retractable lid that can be in a fully retracted, partially retracted or fully retracted position. The disadvantage of this device is that when the lid is fully inserted, the temperature of the entire storage area increases in the box, thereby exceeding the operating temperature of the portable electronic device being charged. Similarly, with the lid partially closed, there is better ventilation and heat dissipation, but the portable electronic device is exposed to the risk of mechanical damage.

The disadvantage of current lid solutions is that they cannot ventilate the space of the box and remove the heat generated during wireless induction charging, but only serve as mechanical protection.

The essence of the invention

The aim of the invention is to provide such a box solution in the center console of the vehicle for wireless charging of portable electronic devices, which ensures both their mechanical protection and ventilation and removal of heat generated during charging from the box. This prevents both mechanical damage and exceeding the operating temperature of the portable electronic device being charged and the wireless charging unit itself.

The mentioned goal is achieved by the cover of the box in the center console of the vehicle for wireless charging of portable electronic devices, the essence of which is that this cover is provided with perforations for ventilation and heat removal from the box. The lid thus serves as a mechanical protection of the portable electronic device being charged, and at the same time there is effective ventilation and heat removal from the box during wireless charging.

Preferably, the lid includes a core and an outer surface arranged thereon, both of which are provided with perforations. At the same time, the perforations in the core are arranged exactly below the perforations in the outer surface, thereby achieving passages in the entire thickness of the lid. The number and dimensions of the perforations are given on the basis of tests for a specific box and wireless charging device. Perforations can create e.g. a logo design on the lid.

Advantageously, the outer surface also includes a gripping projection, with which it is possible to open or move the lid after grasping it, or to close or retract it. Advantageously, the lid is therefore hinged, i.e. equipped with a hinge or hinges, or retractable, i.e. equipped with e.g. guide grooves or other guide elements.

Advantageously, the outer surface or the grip projection itself is provided with a magnetic metal plate, which is used to arrest the lid in the fully unfolded position. The corresponding magnetic metal surface is then located in the space above the box.

Advantageously, the core is made of a hard polymeric material, e.g. polycarbonate (PC) or a copolymer of acrylonitrile, butadiene and styrene (ABS) or a combination thereof, and the outer surface is made of a soft, patterned polymeric material, e.g. thermoplastic olefin (TPO), especially a combination polypropylene (PP) and cross-linked poly(ethylene-propylene-diene) rubber (EPDM). The hard polymer core material provides the strong mechanical properties of the lid, while the soft polymer material provides the surface treatment of the lid, which can serve as a storage surface with anti-slip or non-wetting properties. The soft polymer material can be patterned.

Clarification of drawings

The essence of the invention is further clarified by examples of its implementation, which are described using the attached drawings, in which it shows:

Fig. 1 location of the perforated cover of the box for wireless charging of portable electronic devices in the center console of the vehicle;

Fig. 2 a perforated box lid in the flipped position with a portable electronic device in the box;

Fig. 3 is a perspective view of the perforated lid in a folded arrangement; and Fig. 4 is an exploded perspective view of the perforated lid.

Examples of implementation of the invention

The invention will be further explained by examples of implementation with reference to the respective drawings. Fig. 1 shows an example of the location of the perforated cover 3 of the box 1 for wireless charging of portable electronic devices 2 in the center console of the vehicle. The lid 3 is in the fully folded position and provides mechanical protection for the portable electronic device 2, wirelessly charged inside the box 1, and at the same time for the wireless charging unit itself.

- 2 CZ 310102 B6

In the folded position, only the outer surface 5 of the lid 3, provided with perforations 6 for ventilation and heat removal from the box 1, is visible. To open the lid 3, as shown in Fig. 2, it is advantageous to use the gripping protrusion 7 at one end of the outer surface 5 of the lid 3 .

Fig. 3 and 4 show the lid 3 itself in folded or in an exploded arrangement, which includes the core 4 in the lower part of the lid 3 and the outer surface 5 arranged on the core 4. Perforations 6 pass through the core 4 and the outer surface 5 for ventilation and heat removal from the box 1. For the opening of the lid 3, the core 4 is provided at one end by a pair of hinges 9 and the outer surface 5 is provided at the opposite end with a gripping projection 7. In this case, the outer surface 5, 10 or between the outer surface 5 and the core 4, a magnetic metal plate 8 is inserted to arrest the lid 3 in a fully unfolded position.

Industrial applicability

The above-described perforated lid of the box for wireless charging of portable electronic devices can be used mainly in vehicles, but the lid can also be used to cover other boxes or storage spaces in vehicles where ventilation and the removal of generated heat is desirable.
