Description
Technical Field
The utility model belongs to the technical field of the instrument is made, in particular to watchcase.
Background
The common measurement method is that an air pressure sensitive element is arranged in a corresponding instrument, a sensitive end of the air pressure sensitive element extends out of a meter shell of the instrument, is exposed in the environment to be measured to sense the air pressure, is converted into the size of an electric signal and then is connected into a machine core, and the electric signal is displayed after being processed and analyzed by the machine core.
Taking a sports watch as an example, the sports watch often integrates functions of time display, second reading, heart rate detection and the like, and some special people taking a mountain climber as an example often need the sports watch to have functions of guiding, altitude measurement, air pressure measurement and the like when wearing the sports watch, and in order to realize the function of air pressure measurement on the sports watch, watch manufacturers often adopt a method of arranging an air pressure sensor in the watch, forming a hole in a watch case, and extending a detection end of the air pressure sensor out of the hole to detect the ambient air pressure. For example, in chinese patent application with patent publication number "CN 209044314U", an intelligent barometer watch is disclosed, in which the following are clearly described: including upper cover subassembly, baroceptor subassembly, dust screen, waterproof rubber ring, sealing member, core and lower cover subassembly, the baroceptor subassembly is used for detecting external atmospheric pressure, is provided with the pilot hole on the upper cover subassembly, and baroceptor subassembly, waterproof rubber ring, dust screen and sealing member assemble in the pilot hole in proper order.
In the intelligence atmospheric pressure wrist-watch that discloses in the above-mentioned patent application document promptly with set up the baroceptor subassembly in the wrist-watch to the cooperation is provided with the form of pilot hole on the upper cover subassembly and realizes the atmospheric pressure and measure, when such form is applied to specific instrument, will have following defect: firstly, as for the air pressure sensor assembly, since the air pressure sensor assembly has a sensing device, it usually needs a relatively clean and dry working environment, but at the same time, in order to ensure that the sensing device in the air pressure sensor assembly can keep good interaction with the external atmospheric environment, and often needs to expose the sensing device in the air pressure sensor assembly, it can be seen in the technical solutions described in the above patent application documents that the air pressure sensor assembly is provided for detecting the external air pressure, and at the same time, a waterproof rubber ring and a dustproof net are provided on the outer side of the air pressure sensor assembly for protecting the air pressure sensor assembly, but it should be noted that the waterproof and dustproof functions provided by the waterproof rubber ring and the dustproof net are quite limited, and during long-term use, impurities such as water vapor, dirt or gravel still enter the watch case through the pores on the dustproof net and cover the air pressure sensor assembly, the sensitivity, precision and accuracy of the air pressure sensor component are affected over time, and even the air pressure sensor component fails; secondly, for the circuit layout in the instrument, as described in the above patent application document, in order to ensure that the air pressure sensor assembly can better interact with the external atmosphere, the air pressure sensor assembly is often arranged in the instrument at a position close to the watch case in the prior art, and further a flexible circuit is adopted to feed the electric signal of the air pressure sensor assembly into the mainboard, so that the layout mode not only causes space waste, but also causes the hidden trouble that the circuit is unstable due to the flexible circuit without a stable fixing mode, and if a user holds the instrument to move for many times, the flexible circuit inevitably has the danger of shaking, dislocation and even abrasion disconnection; finally, for the instrument watchcase, for adapting to the baroceptor subassembly and guaranteeing the work of its sensitive device, often need to correspond on the watchcase and set up the pilot hole, because baroceptor subassembly self structure is comparatively complicated, this pilot hole also often has comparatively meticulous, heavy and complicated assembly structure, consequently also is more severe to the processing technology demand of this pilot hole, the watchcase also often leads to fracture or deformation at this pilot hole department accumulated stress, the watchcase leaves weak link in this pilot hole department, will influence the normal use of whole watchcase when serious.
