[0055] refer to Figures 1-5 This application proposes a code table, which includes a housing 100, a main board 200 disposed within the housing 100, and a microphone element 220.

[0056] The outer shell 100 specifically includes an upper shell 120 and a lower shell 110, which are detachably connected. The lower shell 110 forms an upward-opening mounting cavity 101, and the upper shell 120 is connected to the lower shell 110.

[0057] A display screen is formed on the upper housing 120 to display parameters such as riding speed and riding time.

[0058] One end of the lower housing 110 is formed with an end face recess 111 extending toward the mounting cavity 101, and a through flow hole 112 is formed on the inner wall of the end face recess 111.

[0059] The end face recess 111 is specifically formed at one end of the lower housing 110 and is recessed inward.

[0060] The flow hole 112 is located inside the end face recess 111, which can better prevent wind and water, and avoid being touched or blocked.

[0061] Combination Figure 6 Specifically, the mounting cavity 101 is provided with a communicating cavity 151, the flow hole 112 is connected to the communicating cavity 151, and the microphone element 220 is connected to the communicating cavity 151.

[0062] The flow hole 112 is connected to the microphone element 220 in the mounting cavity 101 to realize the microphone element 220's sound recording function and realize the voice interaction function between the rider and the computer.

[0063] Microphone 220 is connected to motherboard 200. Microphone 220 is used to pick up sound through through-hole 112 and send the voice signal to motherboard 200. After the motherboard 200 acquires the audio signal and processes it, it outputs the corresponding command information to the display screen of upper housing 120 to realize the voice interaction function.

[0064] When the cycling computer is installed on a cycling device, the end of the computer with the end face recess 111 is close to the rider, which facilitates the collection of the rider's voice signals and helps to reduce the entry of dust and rainwater.

[0065] For details, please refer to the following: Figure 2 , Figure 4 A USB interface 114 is also provided on the inner wall of the end face recess 111, and an end cover 130 is provided on the end face recess 111, which covers the outside of the USB interface 114 and the flow hole 112.

[0066] In other words, the end cap 130 connected to the end face recess 111 protects the USB interface 114 and the flow hole 112. During riding, the end cap 130 always covers the outside of the USB interface 114 and the flow hole 112, reducing the entry of dust, rainwater and other pollutants.

[0067] When the computer needs to be charged, the end cover 130 is removed, exposing the USB interface 114 for connection to an external charging power source.

[0068] A battery 300 is installed in the inner cavity 101, and a USB interface 114 is connected to the battery 300 for charging the battery 300.

[0069] Combination Figure 13 In some embodiments of this application, the included angle α between the outer wall of the end cap 130 and the horizontal plane satisfies: 45° < α < 90°.

[0070] When the angle α between the outer wall of the end cap 130 and the horizontal plane is within the above range, the sound reception effect is not significantly lost, the odometer is more windproof, waterproof and dustproof, and water and dust do not easily accumulate inside the odometer.

[0071] To prevent the end cap 130 from covering the flow hole 112 and affecting the rider's voice interaction, the end cap 130 is also designed with a connecting area, which includes at least one grid hole 131 formed on the end cap 130.

[0072] In some embodiments of this application, the end cap 130 is provided with a plurality of grille holes 131 at intervals. Considering aesthetics and compatibility with the position of the flow hole 112, the grille holes 131 at least penetrate the portion corresponding to the flow hole 112.

[0073] The end cap 130 is also provided with a baffle 133, which is located inside the connecting area. The baffle 133 is specifically a protective mesh structure. While protecting the flow hole 112 and achieving protection against wind, dust and water, sound can pass through the baffle 133 and the grille hole 131 into the connecting inner cavity 151, which can achieve a good sound reception effect for the microphone element 220.

[0074] In other words, the grille hole 131 allows the rider's voice to be transmitted more directly into the microphone element 220, improving the sound reception; at the same time, it also ensures the structural strength of the corresponding position of the end cap 130, providing protection and enhancing the aesthetics.

[0075] Combination Figure 14 The grille hole 131 is an oblong hole structure formed on the end cap 130 at an incline. The angle β between the center line of the grille hole 131 and the horizontal plane satisfies: 45°<β<90°.

[0076] The aforementioned tilt angle of the centerline of the grille hole 131 helps to reduce water and dust accumulation inside the grille hole 131, and also provides good strength and ease of processing.

[0077] refer to Figures 7-9 In some embodiments of this application, the communicating cavity 151 may be integrally formed within the lower housing 110, or, for ease of processing, the communicating cavity 151 may be formed by a communicating member 150 assembled within the lower housing 110.

[0078] In other words, a connecting member 150 is provided in the mounting cavity 101, the connecting cavity 151 is formed in the connecting member 150, the main board 200 is located above the connecting member 150, and the microphone element 220 is mounted above the main board 200.

[0079] A sound hole 210 is provided on the motherboard 200 at a location corresponding to the position of the microphone element 220. The microphone element 220 is connected to the communicating cavity 151 through the sound hole 210.

[0080] A first connecting portion 152 is formed on the side wall of the connecting member 150 near the end face recess 111, and a second connecting portion is provided on the top of the connecting member 150. The flow hole 112 is connected to the connecting cavity 151 through the first connecting portion 152, and the microphone element 220 is connected to the connecting cavity 151 through the second connecting portion.

[0081] In some embodiments of this application, a plurality of support protrusions 115 are distributed on the side wall of the mounting cavity 101. The top height of the support protrusions 115 is flush with the upper end of the connecting member 150, and the main board 200 is supported on the connecting member 150 and the support protrusions 115.

[0082] To improve the sound reception effect, a first sealing part 170 is provided between the connecting part 150 and the inner wall of the end face recess 111. Specifically, the first sealing part 170 is located on the periphery of the first connecting part 152. A second sealing part 160 is provided between the connecting part 150 and the main board 200. The second sealing part 160 is located on the periphery of the second connecting part.

[0083] The first sealing part 170 and the second sealing part 160 are both made of PU foam sound insulation material such as foam, and are disposed on the periphery of the first connecting part 152 and the second connecting part.

[0084] That is, the first sealing part 170 is provided with an opening at the position corresponding to the first connecting part 152, and the second sealing part 160 is provided with an opening at the position corresponding to the second connecting part, so that the sound is transmitted to the microphone element 220 through the first connecting part 152, the connecting cavity 151 and the second connecting part in a more concentrated manner.

[0085] A waterproof and breathable component 180 is also provided between the inner wall of the first sealing part 170 and the end face recess 111 to prevent external water vapor from entering, while meeting the requirement of audio transmission. The waterproof and breathable membrane is a polymer material, which is an existing material technology and will not be described in detail here.

[0086] A detection element 230 is also provided in the connecting inner cavity 151. The detection element 230 is connected to the main board 200. The detection element 230 is used to detect the air pressure and / or temperature in the connecting inner cavity 151. The temperature, air pressure and other values ​​detected by the detection element 230 in the connecting inner cavity 151 can be displayed on the display screen of the upper housing 120 through the main board 200 for the user to observe.

[0087] refer to Figure 10 , Figure 11 The end cap 130 includes a protective housing and a sealing connection 132 disposed inside the protective housing.

[0088] The sealing connection portion 132 has a USB plug 1321 and a snap-fit ​​portion 1322 extending into the end face recess 111. The USB plug 1321 is used to connect into the USB interface 114, and the snap-fit ​​portion 1322 is connected to the limiting portion 141 to realize the detachable connection of the end cover 130 on the end face recess 111.

[0089] In some other embodiments, the inner side of the end cap 130 is also provided with a sealing connection part 132, and the sealing connection part 132 is provided with a USB plug 1321 and a snap-fit ​​part 1322. The USB plug 1321 is sealed on the USB interface 114, and the snap-fit ​​part 1322 is connected to the end face recess 111 through the adapter 140.

[0090] Specifically, a sound receiving area 1301 and a cover area 1302 are formed on the inner side of the end cover 130. A partition 133 is installed in the sound receiving area 1301, and a USB plug 1321 and a snap-fit ​​part 1322 are installed in the cover area 1302.

[0091] The USB plug 1321 and the partition 133 are located on both sides of the latching part 1322.

[0092] refer to Figure 12 The adapter 140 is fixed to the inner wall of the end face recess 111 by fasteners. A limiting part 141 is also formed on the adapter 140. The snap-fit ​​part 1322 is connected in the limiting part 141. A snap-fit ​​end 1323 is also formed at the end of the snap-fit ​​part 1322. The radial dimension of the snap-fit ​​end 1323 is larger than that of the snap-fit ​​part 1322.

[0093] An outwardly extending fixing part 113 is formed on the inner wall of the end face recess 111, a fixing hole is formed on the fixing part 113, and an internal thread is formed in the fixing hole.

[0094] The adapter 140 is detachably connected to the fixing hole by fasteners. Since the fixing part 113 extends to a certain length of the end face protrusion, an installation gap is formed between the adapter 140 and the inner wall of the end face recess 111.

[0095] The limiting part 141 is a limiting hole formed on the adapter 140. A cutout 142 is formed on the limiting hole. In order to facilitate the connection of the snap-fit ​​part 1322 to the limiting hole, the cutout 142 is designed to be located below the limiting hole.

[0096] Furthermore, guide surfaces that gradually narrow towards the limiting hole are formed on both sides of the cut 142. When the snap-fit ​​part 1322 is connected, it moves along the guide surface into the limiting hole, and the cut 142 opens until the snap-fit ​​part 1322 is connected into the limiting hole. Then, the cut 142 returns to the center under its own restoring force.

[0097] The end of the snap-fit ​​portion 1322 is formed with a snap-fit ​​end 1323. The radial dimension of the snap-fit ​​end 1323 is larger than that of the snap-fit ​​portion 1322 and the limiting hole. The snap-fit ​​portion 1322 is connected to the limiting hole, and the snap-fit ​​end 1323 extends into the installation gap.

[0098] When the end cap 130 is closed, the snap-fit ​​end 1323 and snap-fit ​​part 1322 move towards the inner wall of the end face recess 111 within the limiting hole until the USB plug 1321 is inserted into the USB interface 114.

[0099] Finally, refer to it again. Figure 2 When the end cover 130 is opened, the end cover 130 is pulled outward, the USB plug 1321 is moved out of the USB interface 114, and after the snap-fit ​​end 1323 contacts the inside of the adapter 140, the end cover 130 is flipped at an angle to expose the USB interface 114.

[0100] The end cap 130 is connected to the adapter 140 via the snap-fit ​​part 1322 to achieve a detachable connection of the end cap 130 on the end face recess 111; the USB interface 114 is located inside the end face recess 111, which helps to prevent rainwater, dust and other substances from entering the USB interface 114, and the USB interface 114 is covered with the end cap 130 to further protect the USB interface 114.

[0101] After the USB plug 1321 is removed from the USB interface 114, the snap-fit ​​end 1323 on the snap-fit ​​part 1322 is always connected to the adapter 140, so that the end cover is not lost and the user can operate more conveniently.

[0102] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0103] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
