This utility model relates to the field of testing device technology and discloses a testing device for an automotive cockpit controller, comprising: a main cabinet, which is divided into multiple functional layers along a first direction by partitions, the functional layers being suitable for testing at least one function of the automotive cockpit controller; and a darkroom connected to the main cabinet, the darkroom being suitable for forming a dark space; the main cabinet includes: a first side panel, the first side panel being suitable for mounting the object under test for testing in the darkroom. By dividing the main cabinet into multiple functional layers along the first direction, the parallel testing capability of multiple functions of the automotive cockpit controller is realized. This not only optimizes space utilization but also significantly improves testing efficiency, allowing different functional modules to be tested simultaneously, greatly shortening the overall testing cycle. The connection design of the darkroom provides a controllable dark environment for optically related tests, ensuring the reliability and consistency of test data.

This utility model discloses a connector disassembly and expansion pliers, belonging to the technical field of connector disassembly tools, aiming to solve the technical problems of easy damage and inconvenience of manual disassembly of connectors in the prior art. The connector disassembly and expansion pliers include handles, with a pair of handles. One end of each handle is bent towards each other and respectively provided with a first clamping arm and a second clamping arm. The ends of the handles facing the first and second clamping arms are hinged together. The opening and closing of the first and second clamping arms is controlled by the movement of the handles together or apart. This connector disassembly and expansion pliers, utilizing the synergistic action of the handles, first clamping arms, and second clamping arms, can apply force evenly, avoiding the problem of locking ring breakage due to improper force application. This improves the safety and reliability of connector disassembly and avoids the frequent occurrence of locking ring breakage due to uneven or excessive force when disassembling connectors manually in the past. Furthermore, it is easy to operate.

The utility model belongs to the technical field of motorcycle accessories, and particularly relates to a motorcycle handle which is characterized in that one end of a handlebar is a connecting end used for being connected with a motorcycle body, an anti-skid sleeve is arranged on the outer surface of the handlebar in a sleeving mode and used for improving the comfort degree and the anti-skid performance during holding, and a limiting disc is connected to one end of the handlebar in a threaded mode and used for axially limiting the anti-skid sleeve. The limiting assembly is arranged between the anti-skid sleeve and the limiting disc and used for preventing the anti-skid sleeve from rotating relative to the handlebar, the structure is convenient to assemble and disassemble, and later maintenance and component replacement are facilitated.

This utility model discloses a fully open wearable stereo earphone, including a charging case, an inner tray, earphone bodies, an earphone fixing assembly, and a circuit assembly. The charging case includes an upper box body with a lower box body disposed on the upper box body. The inner tray includes an upper cover, a lower cover and a bonding piece disposed below the upper cover, with the bonding piece fixed to the upper and lower cover respectively. The earphone body is disposed on the earphone fixing assembly, which includes a storage block. A first earphone chamber and a second earphone chamber communicating with the first earphone chamber are disposed on the upper surface of the storage block. The circuit assembly includes a protective shell, which is a cavity structure with an opening at the top and a hollow interior, and has a mounting groove. This fully open wearable stereo earphone adopts a healthy sound solution, combining a wide sound field and a free and comfortable listening experience without intruding into the ears with the convenience of earphones, and does not produce sound leakage.
