Description

Technical Field

[0001] The utility model belongs to the technical field of code meters and relates to a side-button code meter. Background Art

[0002] Existing bicycle computers have their screens and buttons located on the top surface. This requires ample space for these, resulting in a large horizontal dimension and hindering miniaturization. Handlebars are often equipped with brake levers, speed regulators, grips, bells, and other components. Adding a computer to the limited space creates significant limitations on its size. Miniaturization of bicycle computers is a pressing need. Summary of the Invention

[0003] The utility model aims to solve the problems existing in the prior art and proposes a side-key code table, aiming to overcome the defect of the existing code table having a large horizontal size.

[0004] The utility model is achieved in this way:

[0005] A side-button code computer comprises a shell and a screen mounted on the upper end of the shell, wherein a main control board is provided in the shell, and is characterized in that the shell has a vertical mounting cavity, a key board is fixed in the vertical mounting cavity, the key board is electrically connected to the main control board, and side buttons are provided on the outer side wall of the vertical mounting cavity corresponding to the key board.

[0006] By shifting the buttons, which previously occupied the upper surface, to the side, the upper surface is dedicated solely to the screen, optimizing the use of the computer's internal space. This effectively addresses the issue of excessive lateral dimensions due to the concentration of buttons and screen on the upper surface. This design reduces the computer's lateral dimensions, making it adaptable to a wider range of installation environments.

[0007] Preferably, the bottom of the vertical mounting cavity has a first mounting groove, and the lower end of the key panel is embedded in the first mounting groove. The first mounting groove can accurately determine the position of the key panel in the vertical mounting cavity, prevent the key panel from deviating during the installation process, and ensure the accuracy of the corresponding settings of the side buttons and the key panel. After the lower end of the key panel is embedded in the mounting groove, the stability of the entire key system is enhanced to a certain extent. During bicycle riding, it is inevitable to encounter bumps and other situations, and this installation method can reduce the impact of vibration on the key panel, reduce the risk of loosening and displacement of the key panel, and ensure the continuous and stable operation of the code table button function.

[0008] Preferably, the upper edge of the vertical mounting cavity has a second mounting groove, the upper end of the keypad is wider than the lower end, and the upper end of the keypad is embedded in the second mounting groove, forming a double limit at the upper and lower ends.

[0009] Preferably, the upper end of the keypad protrudes above the main control board, and the protruding portion is fixed and electrically connected to the main control board via solder. Soldering secures and electrically connects the protruding portion to the main control board, utilizing the excellent electrical conductivity of solder to ensure stable and accurate transmission of electrical signals from the keypad to the main control board. Furthermore, as the solder cools and solidifies, it forms a strong metal connection, firmly bonding the keypad and main control board together and mechanically securing them, preventing them from separating due to vibration or external forces, and ensuring the stability and reliability of the entire circuit connection.

[0010] Preferably, the housing has an arc-shaped fixing portion, and the lower end of the vertical mounting cavity is arranged corresponding to the arc-shaped fixing portion. This can fully utilize the space of the arc-shaped fixing portion, making the overall volume of the computer smaller and reducing the material used for the housing.

[0011] Preferably, the housing has a main chamber, and the main control board is secured within the main chamber of the housing by screws. The screws pass through pre-set mounting holes on the main control board and screw into corresponding threaded holes in the main chamber of the housing. The friction and compressive force generated by tightening the screws tightly secure the main control board to the housing, ensuring that the main control board is fixed in place within the housing and is not easily displaced by external forces such as vibration and collision. Furthermore, the main chamber provides a relatively enclosed and protected space for the main control board, reducing the impact of the external environment on the main control board.

[0012] Preferably, a trigger through-hole is provided on the side wall of the vertical mounting cavity, and a trigger member passing through the trigger through-hole is provided between the side button and the key panel. The trigger through-hole is provided on the side wall of the vertical mounting cavity, providing a channel for the installation and movement of the trigger member. When the user presses the side button, the mechanical force generated by the side button is transmitted to the key panel via the trigger through-hole through the trigger member. As a force transmission medium, the trigger member accurately conveys the action of the side button to the key panel, thereby closing or disconnecting the corresponding circuit contacts on the key panel, generating electrical signal changes, and realizing the control of various functions of the code table.

[0013] Preferably, the housing is integrally formed. Compared to conventional multi-component assembly, integral molding avoids gaps between components and utilizes the integrity and continuity of the material itself to enhance the structural strength of the housing. This also reduces the number of molds and reduces production costs.

[0014] Preferably, the main control panel and the keypad are arranged perpendicular to each other, which effectively utilizes the three-dimensional space inside the housing, so that the overall volume of the computer can be further reduced while maintaining functional integrity.

[0015] Preferably, the keypad is provided with a first trigger position and a second trigger position distributed vertically, and the side buttons include an upper button and a lower button corresponding to the first trigger position and the second trigger position, respectively. For this type of dual-button code computer, providing a vertical mounting cavity to mount the vertically arranged keypad can better demonstrate the advantages of this structure.

[0016] The present invention has the following beneficial effects: by placing the buttons on the side, the overall horizontal size of the computer is reduced, achieving a miniaturized design. This not only meets the current trend of pursuing exquisite and compact products, but more importantly, it provides more options for handlebar-mounted computer installation, especially when handlebar space is limited.

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] This embodiment provides a code table, such as Figure 1-5As shown, it includes a shell 100 and a screen 200 installed at the upper end of the shell 100, a main control board 300 is provided in the shell 100, the shell 100 has a vertical installation cavity 110, a key board 400 is fixed in the vertical installation cavity 110, the key board 400 is electrically connected to the main control board 300, and a side button 500 is provided on the outer wall of the vertical installation cavity 110 and is corresponding to the key board 400.

[0025] By relocating the buttons, which previously occupied the upper surface, to the side, the upper surface is dedicated solely to the installation of the screen 200, thereby optimizing the use of the computer's internal space. This effectively solves the problem of excessive lateral dimensions being required when the buttons and screen 200 are concentrated on the upper surface. This design reduces the computer's lateral dimensions, making it adaptable to a wider range of installation environments.

[0026] like Figure 3 、 4 As shown, the bottom of the vertical mounting cavity 110 has a first mounting groove 120, into which the lower end of the keypad 400 is inserted. The first mounting groove 120 accurately determines the position of the keypad 400 within the vertical mounting cavity 110, preventing deviation of the keypad 400 during installation and ensuring the accuracy of the corresponding placement of the side buttons 500 and the keypad 400. The insertion of the lower end of the keypad 400 into the mounting groove enhances the stability of the entire keypad system. Bicycling inevitably involves bumps and other obstacles, and this mounting method can reduce the impact of vibration on the keypad 400, lowering the risk of loosening or displacement, and ensuring the continued stable operation of the computer's key functions. In other optional embodiments, the mounting groove can be provided at the lower end of the keypad 400, or simultaneously provided on the keypad 400, with the bottom of the vertical mounting cavity 110 having corresponding ribs that engage with the mounting groove of the keypad 400.

[0027] like Figure 2-4 As shown, the upper edge of the vertical mounting cavity 110 has a second mounting groove 130. The width of the upper end of the keypad 400 is greater than the lower end of the keypad 400, and the upper end of the keypad 400 is embedded in the second mounting groove 130. The upper end is embedded in the second mounting groove 130, forming a double limit at the upper and lower ends. In other optional embodiments, the second mounting groove 130 can also be omitted. The upper end of the keypad 400 abuts against the edge of the main control board 300, and the compressive force on the keypad 400 is transmitted to the main control board 300, which supports the keypad 400.

[0028] like Figure 2 、 5As shown, the upper end of the keypad 400 protrudes above the main control board 300, and the protruding portion is fixed and electrically connected to the main control board 300 via solder 310. Solder 310 secures and electrically connects the protruding portion to the main control board 300. The excellent conductivity of solder 310 ensures that electrical signals from the keypad 400 are stably and accurately transmitted to the main control board 300. Furthermore, during the cooling and solidification process, solder 310 forms a strong metal connection, firmly bonding the keypad 400 to the main control board 300 and mechanically securing them. This prevents them from separating due to vibration or external forces, ensuring the stability and reliability of the entire circuit connection. In other optional embodiments, the upper end of the keypad 400 can also be flush with or lower than the main control board 300, with the keypad 400 and main control board 300 spaced apart and electrically connected via wires.

[0029] like Figure 2 、 3 As shown, the housing 100 has an arcuate fixing portion 140, and the lower end of the vertical mounting cavity 110 is positioned corresponding to the arcuate fixing portion 140. This fully utilizes the space within the arcuate fixing portion 140, reducing the overall size of the computer and the material used in the housing 100. The arcuate fixing portion 140 cooperates with the arcuate buckle hinged thereon to secure the computer to the handlebars of a bicycle.

[0030] like Figure 2 As shown, the housing 100 has a main chamber 150, within which the main control board 300 is secured by screws. The screws pass through pre-set mounting holes in the main control board 300 and screw into corresponding threaded holes within the main chamber 150 of the housing 100. The friction and compressive force generated by tightening the screws securely fasten the main control board 300 to the housing 100, ensuring that the main control board 300 is securely positioned within the housing 100 and is not easily displaced by external forces such as vibration and collision. Furthermore, the main chamber 150 provides a relatively enclosed and protected space for the main control board 300, reducing the impact of the external environment on the main control board 300.

[0031] like Figure 3 、 4As shown, a trigger through-hole 160 is provided on the side wall of the vertical installation cavity 110, and a trigger member 161 passing through the trigger through-hole 160 is provided between the side button 500 and the key panel 400. The trigger through-hole 160 is provided on the side wall of the vertical installation cavity 110, providing a channel for the installation and movement of the trigger member 161. When the user presses the side button 500, the mechanical force generated by the side button 500 is transmitted to the key panel 400 through the trigger through-hole 160 through the trigger member 161. As a force conduction medium, the trigger member 161 accurately conveys the action of the side button 500 to the key panel 400, thereby closing or disconnecting the corresponding circuit contacts on the key panel 400, generating electrical signal changes, and realizing the control of various functions of the code table.

[0032] like Figure 4 As shown, the housing 100 is integrally formed. Compared to traditional multi-component assembly, integral molding avoids gaps between components and utilizes the integrity and continuity of the material itself to enhance the structural strength of the housing 100. It also reduces the number of molds and reduces production costs.

[0033] like Figure 3 、 5 As shown, the main control board 300 and the keypad 400 are arranged perpendicular to each other. This effectively utilizes the three-dimensional space within the housing 100, allowing the computer to further reduce its overall size while maintaining its functional integrity. In other optional embodiments, when the main control board 300 is horizontal, the angle between the keypad 400 and the vertical plane can be within a range of less than 30 degrees, placing the keypad 400 in a relatively tilted position.

[0034] like Figure 1-3 As shown, the keypad 400 is provided with a first trigger position 410 and a second trigger position 420, distributed vertically. The side button 500 includes an upper button 510 and a lower button 520 corresponding to the first trigger position 410 and the second trigger position 420, respectively. For this dual-button computer, providing a vertical mounting cavity 110 to accommodate the vertically mounted keypad 400 can further demonstrate the advantages of this structure. In other optional embodiments, the keypad 400 can also be provided with only one trigger position or more than two trigger positions.
