Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a real-time speed display device for bicycles. Background Technology

[0002] In nighttime or low-light environments, such as dusk, dawn, rainy days, and foggy days, the driver's vision is limited. The bicycle taillight can reflect the lights of vehicles behind or emit its own light, making the bicycle stand out against the dark background. This allows the driver to see the bicycle clearly from a distance, giving them enough time to react and take measures such as braking or swerving, effectively avoiding collisions.

[0003] At the same time, when multiple bicycles are traveling side by side or mixed with other vehicles, the taillights can help people behind quickly and accurately identify a specific bicycle, making it easier to track and maintain a safe distance.

[0004] However, existing taillights are all installed using a single clamping method. While this method is simple, the taillights are susceptible to vibration, impact, and load during use, which can cause them to detach or tilt, thus affecting their performance. In addition, existing taillights do not have a bicycle speed display function, so riders behind cannot directly observe the speed of the bicycle in front while the cyclists are riding in a convoy, resulting in poor safety.

[0005] Therefore, it is necessary to design a bicycle real-time speed display device that is easy to install and can display the vehicle's speed. Utility Model Content

[0006] To address the aforementioned problems, this invention proposes a real-time speed display device for bicycles to more accurately resolve these issues.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model proposes a real-time speed display device for bicycles, including a clamping member at the seat arch of the bicycle saddle, a suspension member hinged to the clamping member, and a lamp body connected to the suspension member. The clamping member includes a fixed seat and a movable seat disposed on the top of the fixed seat and threadedly connected to the fixed seat. Two inner grooves are formed on the surfaces of the movable seat and the fixed seat opposite each other. A pad is movably connected in the inner groove. Both the movable seat and the fixed seat are T-shaped. Two curved ends are provided on one side of the fixed seat. A hinge hole is formed on each of the two curved ends. A hinge shaft that mates with the hinge hole is provided between the two curved ends. The suspension member includes a plate body, a hinge end disposed at the rear end of the plate body and mates with the hinge end, and two suspension ends disposed at the front end of the plate body and arranged in an L-shape. A suspension groove that mates with the suspension ends is provided at the rear end of the lamp body. One end of the suspension groove is closed.

[0009] Furthermore, the lamp body includes a housing, a receiving cavity formed on the housing, and a transparent cover disposed at the front end of the housing and engaging with the housing.

[0010] Furthermore, the present invention includes a storage battery, a GNSS dual-mode speed measurement module, a microprocessor, and an LED analog digital display screen disposed within the cavity, wherein the storage battery is electrically connected to the GNSS dual-mode speed measurement module, the microprocessor, and the LED analog digital display screen.

[0011] Furthermore, the present invention provides an inner groove on one side of the outer shell, and a charging interface connected to the battery is located inside the inner groove. A sealing gasket for sealing the charging interface is movably connected inside the inner groove.

[0012] Furthermore, the fixed seat has a first internal threaded hole through its center, and the movable seat has a second internal threaded hole through its center that is directly opposite the first internal threaded hole. The first internal threaded hole and the second internal threaded hole are internally threaded with screws.

[0013] Furthermore, the fixed seat has protruding limiting posts on the top and on both sides of the first internal thread hole, and the movable seat has insertion grooves on the bottom and on both sides of the second internal thread hole that cooperate with the protruding limiting posts.

[0014] The beneficial effects of this utility model are:

[0015] The advantage of using a T-shaped design for both the fixed and movable seats is that it allows for a clamping groove between them. This groove facilitates the installation of the light body onto the bicycle saddle arch. After the fixed and movable seats are connected, screws can be used to increase the stability of the connection and enhance the gripping stability of the clamping groove on the bicycle saddle arch. The clamping and screw self-locking mechanism between the fixed and movable seats and the bicycle saddle arch maintains stability under vibration, impact, and load changes, preventing loosening or detachment. This ensures the bicycle taillight remains in the correct position during riding, preventing it from being affected by shaking and providing reliable safety. Furthermore, this connection method allows users to fine-tune the taillight's position within a certain range to accommodate different bicycle models and individual rider needs.

[0016] The installation of the hanging end and hanging slot allows users to install the lamp body by hanging. The advantage of the hanging installation method is that it not only makes it easy for users to install and remove the lamp body, but also makes it easy for users to store and carry the lamp body and spare lamp body, so that users can directly replace the lamp body after it is damaged.

[0017] The GNSS dual-mode speed measurement module can simultaneously receive signals from BeiDou and GPS satellites. The data measured by the GNSS dual-mode speed measurement module is transmitted to the microprocessor, which analyzes and processes the data in real time, converting it into metric or imperial data as set by the user, and sending instructions to the LED analog digital display screen. The LED analog digital display screen will then display the corresponding status according to the received instructions. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example

[0027] refer to Figure 1-6 A real-time speed display device for bicycles includes a clamping member 1 attached to the saddle arch of the bicycle seat, a suspension member 2 hinged to the clamping member 1, and a lamp body 3 connected to the suspension member 2. The clamping member 1 includes a fixed base 11 and a movable base 12 disposed on the top of the fixed base 11 and threadedly connected to the fixed base 11. Two inner grooves 13 are formed on the surfaces of the movable base 12 opposite to the fixed base 11, and a pad 14 is movably connected in the inner grooves 13. Both the movable base 12 and the fixed base 11 are T-shaped. The fixed base 11 has two curved ends 111 on one side, and each of the two curved ends 111 has a hinge hole 112. A hinge shaft that mates with the hinge hole 112 is provided between the two curved ends. The suspension member 2 includes a plate 21, a hinge end 23 that is provided at the rear end of the plate 21 and mates with it, and two suspension ends 22 that are provided at the front end of the plate 21 and are arranged in an L shape. The rear end of the lamp body 3 has a suspension groove 31 that mates with the suspension end 22. One end of the suspension groove 31 is closed.

[0028] The advantage of using a T-shaped design for both the fixed seat 11 and the movable seat 12 is that it allows for a clamping groove between them. This groove facilitates the installation of the light body 3 onto the bicycle saddle arch. Furthermore, after the connection is complete, the screw 122 can be used to increase the stability of the connection and enhance the clamping grip on the bicycle saddle arch. The clamping and screw 122 self-locking mechanism between the fixed seat 11 and the movable seat 12 and the bicycle saddle arch maintains stability under vibration, impact, and load variations, preventing loosening or detachment. This ensures the bicycle taillight remains in the correct position during riding, preventing any impact on its warning effect and providing reliable safety. This connection method also allows users to fine-tune the taillight's position within a certain range to accommodate different bicycle models and individual rider needs.

[0029] The setting of the suspension end 22 and the suspension groove 31 makes it convenient for users to install the lamp body 3 by suspension. The advantage of the suspension installation method is that it not only makes it convenient for users to install and disassemble the lamp body 3, but also makes it convenient for users to store and carry the lamp body 3 and the spare lamp body 3, so that users can directly replace the lamp body 3 after it is damaged.

[0030] In this embodiment, the advantage of closing one end of the suspension groove 31 is that it can limit the installation range of the lamp body 3, thereby ensuring the stability of the lamp body 3 during use.

[0031] like Figure 5 and Figure 6 As shown, the lamp body 3 includes a housing 32, a receiving cavity 33 opened on the housing 32, and a transparent cover 34 disposed at the front end of the housing 32 and engaged with the housing 32;

[0032] The cavity 33 contains a battery 4, a GNSS dual-mode speed measurement module 5, a microprocessor 6, and an LED analog digital display screen 7. The battery 4 is electrically connected to the GNSS dual-mode speed measurement module, the microprocessor 6, and the LED analog digital display screen 7.

[0033] The housing 32 and the transparent cover 34 can protect the battery 4, the GNSS dual-mode speed measurement module 5, the microprocessor 6 and the LED analog digital display screen 7.

[0034] The GNSS dual-mode speed measurement module 5 is configured to simultaneously receive signals from BeiDou and GPS satellites. Based on the original Doppler method or the inter-epoch pseudorange difference method, it calculates the real-time speed of the bicycle. The data measured by the GNSS dual-mode speed measurement module 5 is transmitted to the microprocessor 6, which performs real-time analysis and processing of the data and sends commands to the LED analog-digital display screen 7. The LED analog-digital display screen 7 then operates in different states depending on the received commands, such as:

[0035] When the speed stabilizes or increases: the microprocessor 6 sends the speed data to the LED analog digital display screen 7, which displays the real-time speed data and remains constantly lit.

[0036] When the speed decreases slowly: the LED analog digital display screen 7 remains constantly lit, and the LED analog digital display screen 7 displays the real-time decreasing speed.

[0037] When the speed drops rapidly beyond a preset threshold (e.g., 5 m / s) 2 At this time: the microprocessor 6 issues a command to make the LED light analog digital display screen 7 enter a high-brightness, rapid flashing mode to warn cyclists behind to slow down or avoid it in time;

[0038] In this embodiment, the LED light analog digital display screen 7 can display, flash, and illuminate the bicycle speed according to instructions issued by the microprocessor 6;

[0039] In this embodiment, the battery 4 provides power to the GNSS dual-mode speed measurement module 5, the microprocessor 6, and the LED analog digital display screen 7, thereby ensuring the operation of the GNSS dual-mode speed measurement module 5, the microprocessor 6, and the LED analog digital display screen 7.

[0040] like Figure 5 As shown, a recessed groove 35 is provided on one side of the outer casing 32. A charging interface 36 connected to the battery 4 is located in the recessed groove 35. A sealing gasket 37 for sealing the charging interface 36 is movably connected in the recessed groove 35. The charging interface 36 can be connected to an external power source to ensure that the battery 4 can be charged. The sealing gasket 37 can seal the unused charging interface 36, thus protecting the charging interface 36.

[0041] like Figure 3 and Figure 4As shown, a first internal threaded hole 113 is provided through the middle of the fixed base 11, and a second internal threaded hole 121 is provided through the middle of the movable base 12, which is directly opposite to the first internal threaded hole 113. A screw 122 is internally threaded into the first internal threaded hole 113 and the second internal threaded hole 121. The screw 122 can pass through the first internal threaded hole 113 and the second internal threaded hole 121, thereby completing the fixing of the fixed base 11 and the movable base 12 and ensuring the installation of the equipment.

[0042] like Figure 3 and Figure 4 As shown, the top of the fixed base 11 and the two sides of the first internal threaded hole 113 are provided with protruding limiting posts 114, and the bottom of the movable base 12 and the two sides of the second internal threaded hole 121 are provided with insertion grooves 123 that cooperate with the protruding limiting posts 114. The cooperation between the protruding limiting posts 114 and the insertion grooves 123 can initially fix the movable base 12 above the fixed base 11, thereby facilitating the installation of the screws 122 by the workers.

[0043] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.

[0044] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
