[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] In the prior art, there is a helmet that uses a capacitor sheet to sense whether the rider is wearing a helmet; the capacitor sheet and the shielding sheet are respectively attached to the two sides of the inner lining layer. When the capacitor sheet and the shielding sheet are damaged and need to be replaced, they need to be torn off and re-pasted with new capacitor sheets and new shielding sheets. During the pasting, in order to ensure the detection function of the helmet, the pasted capacitor sheet and the shielding sheet need to be kept opposite to each other, which is extremely inconvenient and consumes a lot of time when re-replacing. Therefore, the utility model provides the following embodiments to solve the above problems.

[0027] Embodiment 1:

[0028] like Figure 1 and Figure 2 The helmet liner comprises: a liner body 1, on which a card slot 101 is provided; a card block 2, which is detachably arranged in the card slot 101; a capacitor sheet 3, which is arranged on a side of the card block 2 close to the card slot 101 and located in the card slot 101; and a shielding sheet 4, which is arranged on a side of the card block 2 away from the card slot 101 and is arranged opposite to the capacitor sheet 3.

[0029] In this embodiment, the helmet liner includes a liner body 1, a card block 2, a capacitor sheet 3 and a shielding sheet 4; wherein, a card slot 101 is provided on the liner body 1, and a plurality of card slots 101 can be provided. In this embodiment, two relatively distributed card slots 101 are provided on the outer side of the liner body 1, and a card block 2 is provided in each card slot 101, and a capacitor sheet 3 and a shielding sheet 4 are provided on opposite sides of each card block 2, and the capacitor sheet 3 and the shielding sheet 4 are arranged oppositely, and the side of the card block 2 provided with the capacitor sheet 3 is located in the card slot 101, and the side of the card block 2 provided with the shielding sheet 4 is located outside. In the utility model, the capacitor sheet 3 and the shielding sheet 4 are both arranged on the card block 2. When the capacitor sheet 3 and the shielding sheet 4 are damaged and need to be replaced, it is sufficient to directly replace a card block 2 with the capacitor sheet 3 and the shielding sheet 4 pasted thereon. That is, the capacitor sheet 3, the shielding sheet 4 and the card block 2 are integrated into one to make a standard part. When the capacitor sheet 3 and the shielding sheet 4 are damaged, they can be directly replaced with new standard parts. When replacing, it is only necessary to dismantle the old card block 2 and install the new standard part. The replacement is very quick and convenient.

[0030] As a further solution, the capacitor sheet 3 is arranged at one side of the card slot 101 and is arranged opposite to the shielding sheet 4. Specifically, in this embodiment, the capacitor sheet 3 is attached to the inner side of the card slot 101, and the shielding sheet 4 is arranged on the outer side of the card block 2, and the capacitor sheet 3 and the shielding sheet 4 are arranged opposite to each other. The capacitor sheet 3 and the shielding sheet 4 can not only be integrated on the card block 2, but also be arranged on the inner tank body 1 and the card block 2 respectively.

[0031] As a further solution, the capacitor sheet 3 and the shielding sheet 4 are detachably arranged on the card block 2. Specifically, the capacitor sheet 3 and the shielding sheet 4 are glued to both sides of the card block 2, that is, the capacitor sheet 3, the shielding sheet 4 and the card block 2 can be separated, and it is very convenient to recycle any one of them, for example, they can be glued with double-sided tape.

[0032] In this embodiment, the block 2 is engaged with the slot 101 or connected by screws. Specifically, the block 2 and the slot 101 are loosely fitted or fixedly connected by screws, which facilitates the later disassembly and fixing of the block 2.

[0033] As a further solution, when the block 2 is arranged in the slot 101, the outer side of the block 2 and the outer side of the inner liner body 1 are located on the same arc surface, that is, when the block 2 is embedded in the slot 101, the block 2 and the inner liner body 1 are integrated into one, and the block 2 will not be abrupt or concave on the inner liner body 1, which is beneficial to improving the overall structural strength of the inner liner body 1.

[0034] As a further solution, the capacitor sheet 3 and the shielding sheet 4 are both made of copper foil, which has good conductivity, low cost and good comprehensive performance.

[0035] In this embodiment, a mounting groove 5 for mounting a control module (not shown) is provided on the top of the outer side of the liner body 1. Specifically, a helmet liner provided by the utility model is used for a helmet with a function of checking whether a rider is wearing a helmet, so when a mounting groove 5 for mounting a control module is provided on the helmet liner, when the control module is installed in the mounting groove 5, the capacitor sheet 3 is connected to a capacitor detection device (not shown) in the control module, and the shielding sheet 4 is connected to a ground terminal of a control circuit board (not shown) in the control module, and whether the rider is wearing a helmet is determined by testing the change in the capacitance value.

[0036] As a further solution, the outer side of the helmet liner is provided with a plurality of reinforcing ribs 6. By providing the reinforcing ribs 6 on the outer side of the helmet liner, the structural strength of the helmet liner is enhanced, making the helmet more impact-resistant.

[0037] As a further solution, the thickness of the capacitor sheet 3 and the shielding sheet 4 is 0.01 mm-1 mm. Specifically, considering the detection function of the helmet and the cost problem, the thickness of the capacitor sheet 3 and the shielding sheet 4 is 0.02 mm or 0.03 mm.

[0038] Embodiment 2:

[0039] This embodiment also provides a safety helmet, which includes the helmet liner described in any one of the first embodiments.

[0040] In summary, the embodiment of the utility model provides a helmet liner, including: a liner body 1, on which a card slot 101 is provided; a card block 2, which is detachably arranged in the card slot 101; a capacitor sheet 3, which is arranged on a side of the card block 2 close to the card slot 101 and located in the card slot 101; a shielding sheet 4, which is arranged on a side of the card block 2 away from the card slot 101 and arranged opposite to the capacitor sheet 3. In the utility model, the capacitor sheet 3 and the shielding sheet 4 are both arranged on the card block 2. When the capacitor sheet 3 and the shielding sheet 4 are damaged and need to be replaced, a card block 2 with the capacitor sheet 3 and the shielding sheet 4 pasted thereon can be directly replaced, that is, the capacitor sheet 3, the shielding sheet 4 and the card block 2 are integrated into one body to form a standard part. When the capacitor sheet 3 and the shielding sheet 4 are damaged, they can be directly replaced with new standard parts. When replacing, only the old card block 2 needs to be disassembled and the new standard part needs to be installed. The replacement is very fast and convenient.
