Description

Technical field

[0001] The utility model relates to a CAN bus equipment testing device. [Background Technology]

[0002] The CAN bus is a multi-master serial communication bus. Its basic design specifications require high bit rates, strong immunity to electronic interference, and the ability to detect any errors. The CAN bus is used in automotive electrical control systems, elevator control systems, safety monitoring systems, medical equipment, textile machinery, and ships. However, current CAN bus test equipment on the market lacks protective cases, leaving exposed interfaces and screens susceptible to scratching when the equipment is idle.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0004] The purpose of the present invention is to overcome the above problems. We provide a CAN bus equipment testing device, which solves the problem of equipment scratches.

[0005] To achieve the above-mentioned purpose, the utility model provides a CAN bus equipment testing device, which includes a test body and an outer cover. The side of the test body is provided with a CAN interface, a power interface, a data interface and an indicator light. The top surface of the test body is provided with a display screen and function keys. The outer cover is provided on the outer surface of the test body and covers at least the top surface and side surfaces of the test body. A first magnetic attraction part is provided in the outer cover, and a second magnetic attraction part that cooperates with the first magnetic attraction part for magnetic attraction is provided on the test body.

[0006] In one or more embodiments, a through hole is formed on the top surface of the outer cover for a finger to pass through, and the through hole is offset from the display screen and the function buttons.

[0007] In one or more embodiments, the through hole is located in the middle of the top surface of the outer cover, and the diameter of the through hole is 15MM-23MM.

[0008] In one or more embodiments, a cotton padding layer is provided on the inner side of the outer cover, and the cotton padding layer is adhesively fixed to the inner side of the outer cover.

[0009] In one or more embodiments, the outer cover is an integrally-molded plastic outer cover, and an outer side surface of the outer cover is provided with a concave anti-slip structure.

[0010] In one or more embodiments, the first magnetic attraction portion is disposed on the inner top surface of the outer cover, and the second magnetic attraction portion is disposed inside the test body. The first magnetic attraction portion and the second magnetic attraction portion are magnets.

[0011] Compared with the background technology, the present invention has the following effects: the test body is provided with an outer cover, and when the test body is idle or in storage, the outer cover protects important functional positions such as various interfaces and screens of the test body, thereby reducing the possibility of scratches on the test body.

Brief Description of the Drawings

[0014] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0015] See attached Figure 1-2 The present application provides a CAN bus device testing device, which includes a test body 1 and an outer cover 2. The side of the test body is provided with a CAN interface, a power interface 3, a data interface 4 and an indicator light 5, and the top surface of the test body is provided with a display screen and function buttons. The outer cover 2 is provided on the outer surface of the test body and at least covers the top surface and side surfaces of the test body 1. In this way, the CAN interface, power interface 3, data interface 4 and indicator light 5, display screen and function buttons and other structures are protected by the outer cover, which can avoid problems such as scratches, dust accumulation, and water ingress. A first magnetic attraction part 6 is provided in the outer cover 2, and a second magnetic attraction part 7 that cooperates with the first magnetic attraction part for magnetic attraction is provided on the test body. Through the cooperation of the first magnetic attraction part and the second magnetic attraction part, it is ensured that the outer cover and the test body are not easily separated.

[0016] The top surface of the outer cover 2 is provided with a through hole 8 for a finger to pass through. The through hole is offset from the display screen and function keys. Specifically, the through hole 8 is provided in the middle of the top surface of the outer cover 2. The diameter of the through hole is 15MM-23MM, preferably 15MM, 18MM and 20MM. Within this size range, a finger can pass through the through hole, and then the test body can be pushed out of the outer cover for use.

[0017] The inner side of the outer cover 2 is provided with a cotton pad layer 9, which is bonded and fixed to the inner side of the outer cover. The cotton pad layer can play a buffering role and avoid mutual friction and scratches between the test body and the outer cover, thereby protecting the test body.

[0018] The outer cover 2 is a plastic outer cover formed by injection molding. The plastic outer cover structure is light and low in cost. A concave anti-slip structure 10 is provided on the outer side of the outer cover.

[0019] The first magnetic attraction portion 6 is provided on the inner top surface of the outer cover 2, and the second magnetic attraction portion 7 is provided inside the test body 1 to prevent the second magnet from being exposed and affecting the aesthetics of the test body. The first magnetic attraction portion and the second magnetic attraction portion are magnets.
