Methods for fastening or coupling dissimilar materials to each other may include providing a first component with a first through hole and a second component with a second through hole that is at least partly aligned with the first through hole. A mixture including a first material and a second material may be injected into the aligned through holes of the first component and the second component. The mixture of the first material and the second material may expand in the through holes, e.g., due to a chemical reaction, thereby connecting the first component and the second component together.

A fastener includes an elongated shaft having a first end, a second end, and a shaft body, a head portion, and a threaded portion. At least one inner feed channel extends through the head portion and the shaft body and terminates proximal to the threaded portion. The fastener has a plurality of flutes formed along and circumferentially spaced around an outer surface of the shaft body and an outer surface of the head portion. Each flute has a first end and extends from a first location proximal to the threaded portion, along the outer surface of the shaft body, and radially outward along the outer surface of the head portion. The fastener further has one or more lateral feed channels formed laterally through the shaft body and connecting the inner feed channel to at least two opposing flutes on the outer surface of the shaft body.

Seal (3) comprising at least two deformable shells (1,1), each one of the shells containing a component and comprising a membrane, characterized in that bringing the component contained in one shell (1) into contact with the component contained in another shell (1) causes the mixture of the components to crosslink. Use of the seal for wedging electrochemical generators in position in a battery, particularly lithium generators.

A segment for an annular structure is disclosed. The segment includes an arcuate body extending between a first end and a second end. The segment includes a first plurality of interlocking portions extending from the first end and a second plurality of interlocking portions extending from the second end. Each interlocking portion includes a first leg and a second leg partially embedded in the arcuate body and a connecting portion connecting the first leg and the second leg, the connecting portion external to the arcuate body. The segment also includes a flange proximal to the first end and the second end of the arcuate body. Each flange includes a first spacing portion that extends radially outward from the outside surface and a second extending portion that extends distally from the main body portion.

An electric vehicle thermal management system and an electric vehicle using the thermal management system, wherein a passenger cabin is heated by the heat dissipated from a battery and/or a motor, and the battery and the electric motor are connected in different cooling paths. Heat is supplied to the passenger cabin by using the heat absorbed by cooling liquid from the battery and/or the motor, so that the electric power of the electric vehicle can be effectively utilized to increase the endurance mileage of the electric vehicle.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

A joined structure includes a joint section in which a plurality of tubular bodies formed of a ceramic-based composite material are joined to each other such that end surfaces of the tubular bodies abut each other via an intermediate material. The joint section is configured such that each of the end surfaces of the joined tubular bodies is inclined from one of an inner surface and an outer surface of the tubular body toward the other.

The present disclosure relates to a thermal dissipation system of an electric vehicle that includes: a heat exchanger arranged at the front part of the electric vehicle for providing heating or cooling to an air conditioning system of the electric vehicle; a first heat sink and a second heat sink, which are respectively arranged at the two sides of the front part of the heat exchanger; a number of rotatable and adjustable air deflectors for changing the flow direction of the air flowing through the heat dissipation system. Temperature sensors are included within the thermal dissipation system for sensing the working temperatures and the environmental temperatures of a battery pack and a motor of the electric vehicle. Opening and closing states of the air deflectors are adjusted in accordance with data provided by the temperature sensors.

A visual inspection method includes the following steps: (a) placing a material between a pair of parts, wherein at least one of the pair of parts defines at least one thru-hole sized to partly receive the material; (b) pressing the pair of parts together until the material is partly displaced into the thru-hole (or merely moving the pair of parts toward each other until the material is partly displaced into the thru-hole); and (c) visually inspecting the one thru-hole to verify that the material is partly disposed in the thru-hole after pressing the pair of parts together (or moving the pair of parts toward each other).

Vehicle operating systems for operating a vehicle having a driving seat for a vehicle driver and at least one passenger seat for passengers are described. The vehicle operating system may include one or more camera devices for shooting images of hand actions of the driver or images of hand actions of a passenger, and a storage device for storing operating signals corresponding to hand actions. A processing device may be configured to select the driver or the passengers as a gesture command operator, and to control the camera device to shoot hand action images of the selected gesture command operator. The command system may also be configured to convert the shot hand action images into corresponding operating signals according to hand action indicia stored in the storage device. The operating signals may be sent to execution devices, that execute the corresponding operations.
