[0038] In the description of the present invention, it should be understood that the terms "first," "second," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0039] The present invention provides a control box 10 for a shared two-wheeled vehicle. Figure 1 and Figure 2 The control box 10 of the present invention includes a base assembly and a top shell 12. The base assembly is mounted on a two-wheeled vehicle and serves as a support structure for the other components of the control box 10. The base assembly includes a bottom shell 11, and a top shell 12 is mounted on the bottom shell 11 and connected to the top shell 12 to form a housing cavity. The housing cavity is used to accommodate the other components of the control box 10 and provide protection.

[0040] Figure 3 、 Figure 4 and Figure 5 1 is a schematic diagram of the structure of the control box 10 of this embodiment observed from different angles after removing the top shell 12. Figure 3-Figure 5 The bottom case 11 has a device mounting area 111 on one end facing the top case 12. This area provides mounting locations for one or more electrical components of the control box 10. The control box 10 includes an antenna bracket 13, multiple antennas, and a control circuit board 15. These antenna brackets 13 and control circuit board 15 are located within the housing cavity and connected to the bottom case 11. The antenna bracket 13 serves as a support and positioning structure for the multiple antennas within the control box 10. The antennas are electrically connected to corresponding functional circuits on the control circuit board 15 to implement the corresponding signal transmission and reception functions.

[0041] Figure 6 This is a schematic diagram of the structure of the antenna bracket of the embodiment of the utility model. Figure 3-Figure 6 The antenna bracket 13 has a supporting portion 131 and a raised portion 132. The supporting portion 131 is used to connect with the bottom shell 11, for example, referring to Figure 3The support portion 131 may be provided with a plurality of through-holes, and the device mounting area 111 may be provided with a support platform corresponding to the support portion 131. The support portion 131 may be fixed to the corresponding support platform by bolts passing through the through-holes in the support portion 131, thereby securing the antenna bracket 13 to the bottom shell 11. The raised portion 132 is raised relative to the support portion 131 in a direction away from the bottom shell 11. A plurality of mounting surfaces for mounting antennas are provided on the side of the raised portion 132 facing away from the bottom shell 11. The plurality of antennas in the control box 10 are respectively arranged on the corresponding mounting surfaces. The antennas are arranged on the surface of the raised portion 132 facing away from the bottom shell 11, so that when the control box 10 is installed on the two-wheeled vehicle, the radiating surface of the antenna can face the side away from the vehicle frame 20, which is conducive to ensuring the antenna's signal transmission and reception effect. Preferably, the top shell 12 is made of a non-conductive material, such as a non-conductive plastic material, to avoid interference with the antenna's signal transmission and reception.

[0042] The multiple antennas of the control box 10 include a positioning antenna 141, which is electrically connected to the control circuit board 15 and is used to realize the satellite positioning function. The positioning antenna 141 can be an antenna for realizing positioning based on one or more satellite positioning systems such as the Global Positioning System (GPS), the Beidou Satellite Navigation System, the GLONASS Satellite Navigation System (Glonass), and the Galileo Satellite Navigation System (Galileo satellite navigation system). In an embodiment of the present invention, preferably, the positioning antenna 141 is a single dual-frequency GNSS antenna. GNSS (Global Navigation Satellite System) refers to all satellite navigation systems, including global, regional and enhanced ones, such as GPS, Glonass, Galileo, Beidou Satellite Navigation System, and related enhancement systems, such as the Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay System (EGNOS) and the Multifunctional Transport Satellite Augmentation System (MSAS), etc., and also covers other satellite navigation systems under construction and to be constructed. The single-chip dual-frequency GNSS antenna covers two different frequency bands on a single chip. While reducing the size of the positioning antenna 141, it can ensure a large number of satellite searches and high positioning accuracy, and can maintain good positioning effects even in complex environments surrounded by high-rise buildings in cities.

[0043] The raised portion 132 has a first mounting surface 1321 on the side facing away from the bottom housing 11. The positioning antenna 141 is mounted on the first mounting surface 1321. For example, the positioning antenna 141 can be secured to the first mounting surface 1321 by fasteners, adhesive bonding, or other means. The antenna bracket 13 is structured so that when the control box 10 is mounted on the two-wheeled vehicle, the positioning antenna 141 faces upward. In this embodiment, "positioning antenna 141 faces upward" means that the radiating surface of the positioning antenna 141 faces directly above or diagonally above the vehicle. In other words, the positioning antenna 141 is mounted on the vehicle with its radiation surface facing the sky. This helps ensure the signal transmission and reception performance of the positioning antenna 141, thereby ensuring the response speed and positioning accuracy of the satellite positioning function of the control box 10. Preferably, the first mounting surface 1321 is configured so that when the control box 10 is mounted on the two-wheeled vehicle, the angle between the positioning antenna 141 and the horizontal plane is less than 20°, thereby further ensuring the signal transmission and reception performance of the positioning antenna 141.

[0044] In a feasible implementation, a first angle is defined between the first mounting surface 1321 and the bottom shell 11, and the first angle is an acute angle, that is, the first mounting surface 1321 and the bottom shell 11 are arranged to be relatively inclined. When the control box 10 is installed on the two-wheeled vehicle at an angle, the first angle between the first mounting surface 1321 and the bottom shell 11 can enable the positioning antenna 141 installed on the first mounting surface 1321 to be lifted to a certain angle relative to the bottom shell 11, thereby adjusting the placement angle of the radiation surface of the positioning antenna 141. The specific size of the first angle is set according to the installation position and placement posture of the control box 10 on the two-wheeled vehicle, so that when the control box 10 is installed at a predetermined position on the two-wheeled vehicle, the angle between the positioning antenna 141 and the horizontal plane is within a preset angle range.

[0045] In addition to the positioning antenna 141, the multiple antennas of the control box 10 may also include other types of antennas, which can be selected based on the needs of the application scenario of the control box 10. In some embodiments, the control box 10 includes a short-range communication antenna 142, which is electrically connected to the control circuit board 15 for implementing short-range wireless communication. The short-range communication antenna 142 can be, for example, a Bluetooth antenna, an NFC antenna, a Wi-Fi antenna, or other antennas for short-range wireless communication. In this embodiment, the short-range communication antenna 142 can be a Bluetooth antenna.

[0046] Reference Figure 3-Figure 5The raised portion 132 includes multiple mounting surfaces facing away from the bottom shell 11, including a second mounting surface 1322. The short-range communication antenna 142 is located on this second mounting surface 1322. The first mounting surface 1321 and the second mounting surface 1322 are tilted at a certain angle, so that the radiation surface of the short-range communication antenna 142 and the radiation surface of the positioning antenna 141 face different directions, which helps prevent signal interference between them. In this embodiment, the antenna bracket 13 is configured so that when the control box 10 is mounted on the two-wheeled vehicle, the short-range communication antenna 142 faces the rear of the two-wheeled vehicle. In this embodiment, "the short-range communication antenna 142 faces the rear of the two-wheeled vehicle" means that the radiation surface of the short-range communication antenna 142 faces directly behind or diagonally behind the two-wheeled vehicle. In some application scenarios, the short-range communication antenna 142 can establish a communication connection with wireless road studs installed on the road to facilitate parking and parking management for two-wheeled vehicles. Optionally, the wireless road stud is a Bluetooth road stud, and the short-range communication antenna 142 accordingly includes a Bluetooth antenna. Preferably, the first mounting surface 1321 is positioned so that when the control box 10 is mounted on a two-wheeled vehicle, the radiation surface of the short-range communication antenna 142 is substantially parallel to the axle of the rear wheel of the two-wheeled vehicle. This arrangement is advantageous in maintaining the left-right symmetry of the signal radiation of the short-range communication antenna 142 relative to the two-wheeled vehicle, so that when the two-wheeled vehicle is parked, the short-range communication antenna 142 can communicate with the wireless road spikes to accurately determine the parking position and posture of the two-wheeled vehicle.

[0047] In some embodiments, reference Figure 5 The control box 10 also includes a mobile communication antenna 143, which is electrically connected to the control circuit board 15 and is used to implement wireless communication with the server. The mobile communication antenna 143 can be, for example, a 2G antenna, a 3G antenna, a 4G antenna, a 5G antenna, or another type of mobile communication antenna 143. In this embodiment, the mobile communication antenna 143 can be an LTE antenna. The plurality of mounting surfaces of the raised portion 132 facing away from the bottom case 11 include a third mounting surface 1323, on which the mobile communication antenna 143 is disposed. The third mounting surface 1323 is tilted relative to the first mounting surface 1321 and the second mounting surface 1322, respectively. That is, the first mounting surface 1321, the second mounting surface 1322 and the third mounting surface 1323 are tilted relative to each other, so that the radiation surface of the positioning antenna 141, the radiation surface of the short-range communication antenna 142 and the radiation surface of the mobile communication antenna 143 are staggered and face different directions, which is beneficial to prevent signal interference between the positioning antenna 141, the short-range communication antenna 142 and the mobile communication antenna 143.

[0048] The specific location of the third mounting surface 1323 can be set based on the signal radiation requirements of the mobile communication antenna 143. Optionally, in one embodiment, the raised portion 132 of the antenna bracket 13 has a shape similar to a triangular prism, with one side of the triangular prism facing the bottom housing 11, and the other two sides corresponding to the first mounting surface 1321 and the second mounting surface 1322, respectively. The third mounting surface 1323 is located on one of the bottom surfaces of the triangular prism. This allows the mobile communication antenna 143 to be positioned laterally when mounted on the two-wheeled vehicle, reducing signal interference with the positioning antenna 141 and the short-range communication antenna 142.

[0049] Optionally, the area of the first mounting surface 1321 is larger than the areas of the second mounting surface 1322 and the third mounting surface 1323. Since the positioning antenna 141 has higher requirements for the installation angle and is relatively large to ensure positioning accuracy, the larger surface area of the antenna bracket 13 can be provided for the installation of the positioning antenna 141, while the short-range communication antenna 142 and the mobile communication antenna 143 are arranged on the second mounting surface 1322 and the third mounting surface 1323, which are smaller than the first mounting surface 1321. This can rationally allocate the surface space of the raised portion 132, which helps to reduce the overall volume of the antenna bracket 13, thereby ensuring a smaller overall volume of the control box 10.

[0050] In some embodiments, reference Figure 3 、 Figure 5 and Figure 7 The control circuit board 15 is fixed to the side of the antenna bracket 13 opposite to the bottom shell 11 and connected to the antenna bracket 13. For example, the control circuit board 15 can be fixedly connected to the antenna bracket 13 by screws. The contour shape of the side of the antenna bracket 13 opposite to the device mounting area 111 can be adapted to the control circuit board 15 so that the antenna bracket 13 can better support the control circuit board 15. When assembling the control box 10, the control circuit board 15 can be connected to the antenna bracket 13 first, and then the antenna bracket 13 can be buckled onto the device mounting area 111 of the bottom shell 11 and the antenna bracket 13 can be fixed to the bottom shell 11. In this way, the control circuit board 15 can be fixed between the antenna bracket 13 and the bottom shell 11, which can provide a certain degree of protection for the control circuit board 15.

[0051] In this embodiment, the control circuit board 15 has a grounding structure, and the antenna bracket 13 is connected to the grounding structure via a conductive material (not shown). The specific form of the grounding structure and the conductive material can be selected based on actual needs. For example, the grounding structure can be a dedicated grounding layer on the control circuit board 15 or other conductive structure connected to the grounding layer. The conductive material can be conductive metal, conductive rubber, conductive foam, or other conductive materials. In one embodiment, the control circuit board 15 has a grounding surface on the side opposite the antenna bracket 13. This grounding surface serves as the grounding structure of the control circuit board 15, and the conductive material can be disposed between the antenna bracket 13 and the grounding surface. For example, the conductive material can be conductive foam, which fills the gap between the edge of the antenna bracket 13 and the control circuit board 15, with one side abutting the antenna bracket 13 and the other side abutting the grounding surface. Thus, the conductive material grounds the antenna bracket 13, thereby reducing electromagnetic interference to the antenna mounted on the antenna bracket 13.

[0052] The antenna and the control circuit board 15 can be electrically connected to achieve feeding. In one embodiment, at least one of the positioning antenna 141, the short-range communication antenna 142 and the mobile communication antenna 143 can be fed by the feeder 161. The raised portion 132 has a through opening, the position of the opening corresponds to the position of the antenna fed by the feeder 161, and the feeder 161 passes through the opening to achieve electrical connection between the control circuit board 15 located on the opposite side of the antenna bracket 13 and the bottom shell 11 and the corresponding antenna. In this embodiment, the positioning antenna 141 can be fed by the feeder 161. Figure 3 and Figure 4 The short-distance communication antenna 142 is electrically connected to the control circuit board 15 through the feeder 161 , so that the control circuit board 15 feeds power to the short-distance communication antenna 142 .

[0053] In one embodiment, reference Figure 5 The control circuit board 15 has an interface 151 for feeding the antenna on the side facing away from the bottom shell 11. The edge of the control circuit board 15 protrudes from the edge of the antenna bracket 13, and the interface 151 is also exposed from the edge of the antenna bracket 13. The control box 10 also includes a feeding spring 162. At least one of the short-range communication antenna 142 and the mobile communication antenna 143 is electrically connected to the interface 151 through the feeding spring 162. For example, referring to Figure 5 The mobile communication antenna 143 is electrically connected to the control circuit board 15 through the feeding spring 162. The control circuit board 15 is provided with an interface 151 at positions corresponding to the mobile communication antenna 143. The feeding spring 162 is connected between the mobile communication antenna 143 and the interface 151.

[0054] Reference Figure 1 、 Figure 3-Figure 4as well as Figures 8-10 In some embodiments, the base assembly further includes a protective shell 18. The protective shell 18 has a mounting groove 181, into which the bottom shell 11 is mounted. The sidewalls of the mounting groove 181 are configured to at least partially obstruct the seam between the top shell 12 and the bottom shell 11, thereby providing better protection. Optionally, the sidewalls of the mounting groove 181 are configured to be higher than the position of the control circuit board 15 within the mounting groove 181, thereby providing better protection for the control circuit board 15.

[0055] In some embodiments, the base assembly can be at least partially made of metal. For example, the end surface of the bottom shell 11 opposite the support portion 131 or the protective shell 18 can be made of metal, and a certain distance is maintained between the metal material in the base assembly and the antenna on the antenna bracket 13. As a result, the metal material in the base assembly can act as a reflector, thereby enhancing the radiation of the antenna in certain directions. For example, for the positioning antenna 141, the angle between the positioning antenna 141 and the end surface of the base assembly is relatively small, and the metal material of the base assembly acts as a reflector, which helps to improve the satellite search speed and positioning accuracy of the positioning antenna 141.

[0056] The protective shell 18 has a third connecting structure 183 and a fourth connecting structure 184. The protective shell 18 is fixedly connected to the bottom shell 11 via the third connecting structure 183, and the fourth connecting structure 184 is used to fix the protective shell 18 to the frame 20. In this embodiment, the third connecting structure 183 is a through-hole extending through the bottom of the mounting slot 181. A threaded hole corresponding to the third connecting structure 183 is provided on the side of the bottom shell 11 opposite the bottom of the mounting slot 181. The bottom shell 11 can be secured to the protective shell 18 by sequentially passing bolts through the third connecting structure 183 and the threaded holes corresponding to the third connecting structure 183 in the bottom shell 11 and tightening them. The fourth connecting structure 184 can be a hole, and bolts can be passed through the fourth connecting structure 184 and the corresponding structure on the frame 20 of the two-wheeled vehicle to lock the protective shell 18 to the frame 20.

[0057] In this embodiment, the bottom shell 11 has a protrusion 115 on the side opposite to the top shell 12. Figure 10 As shown, a mounting hole 182 corresponding to the protrusion 115 is formed at the bottom of the mounting groove 181, and the protrusion 115 passes through the mounting hole 182. Optionally, the mounting hole 182 is a through hole.

[0058] In an optional embodiment, the protrusion 115 includes a battery slot 116, and the control box 10 also includes a battery 19, which is removably installed in the battery slot 116. The battery slot 116 is provided with a battery interface that is electrically connected to the control circuit board 15. When the battery 19 is installed in the battery slot 116, it is electrically connected to the battery interface, thereby achieving an electrical connection with the control circuit board 15. The protrusion 115 is provided through the mounting hole 182 and protrudes from the protective shell 18, so that the battery slot 116 is exposed outside the protective shell 18, facilitating the installation and removal of the battery 19.

[0059] In an alternative embodiment, the bottom housing 11 has a through-hole 118 that communicates with the mounting hole 182. The control box 10 further includes a cable 193. One end of the cable 193 is disposed within the accommodating cavity and electrically connected to the control circuit board 15. The other end of the cable 193 passes through the base assembly via the cable 193 and the mounting hole 182, thereby electrically connecting the control box 10 to other structures on the two-wheeled vehicle. For example, the cable 193 can electrically connect the control circuit board 15 to a lock body 40 provided on the two-wheeled vehicle for locking the two-wheeled vehicle.

[0060] In an optional embodiment, the protrusion 115 has a sound hole 117 that communicates with the accommodating cavity, and the control box 10 further includes a speaker 192. Speaker 192 is disposed within the accommodating cavity at a position opposite to sound hole 117. For example, it can be fixed to the bottom housing 11 at a position corresponding to sound hole 117. The sound-emitting structure of speaker 192 is opposite to sound hole 117, and can play a predetermined sound through sound hole 117 to provide a prompt or other effect.

[0061] In the embodiment of the present invention, the top shell 12 and the bottom shell 11 are sealed by a sealing structure to prevent liquid or dust from entering the accommodating cavity and causing damage to the control circuit board 15, antenna and other components in the accommodating cavity. Figure 11 This is a schematic diagram of the internal structure of the top shell of the control box of the embodiment of the present utility model. Figure 3 and Figure 11In this embodiment, the bottom shell 11 has a first connection end surface 112, which is arranged on the periphery of the device mounting area 111, and the top shell 12 has a second connection end surface 121 opposite to the first connection end surface 112. When the top shell 12 is snapped onto the bottom shell 11, the first connection end surface 112 and the second connection end surface 121 are connected. The bottom shell 11 also has a flange 113, which surrounds the periphery of the device mounting area 111 and is located between the first connection end surface 112 and the device mounting area 111, and can prevent liquid from entering the device mounting area 111. The second connection end surface 121 has a sealing groove 122 that matches the contour of the flange 113. When the top shell 12 is snapped onto the bottom shell 11, the sealing groove 122 is located on the outside of the flange 113. The control box 10 also includes a sealing ring 17, which is arranged in the sealing groove 122 and partially protrudes from the sealing groove 122. When the top shell 12 and the bottom shell 11 are connected, the sealing ring 17 is arranged on the outer periphery of the flange 113 and abuts against the first connecting end face 112, thereby filling the gap between the top shell 12 and the bottom shell 11 to achieve a good sealing effect.

[0062] The first connection end surface 112 is provided with a first connection structure 114, and the second connection end surface 121 is provided with a second connection structure 123 corresponding to the first connection structure 114. The second connection structure 123 is disposed outside the sealing groove 122. The first connection structure 114 and the second connection structure 123 are used to secure the top shell 12 to the bottom shell 11. In this embodiment, the first connection structure 114 may include a plurality of through holes, and the second connection structure 123 may include a threaded hole. Bolts pass through the first connection structure 114 and then connect and lock with the second connection structure 123 to secure the top shell 12 to the bottom shell 11.

[0063] Reference Figure 2 and Figure 8 The center of the top shell 12 bulges relative to the edge, away from the bottom shell 11. In other words, the center of the top shell 12 bulges relative to the second connection end surface 121, away from the bottom shell 11, forming a hood-like structure. The shape and height of the bulge in the center of the top shell 12 can be designed based on the components mounted on the component mounting area 111. For example, the shape can be similar to that of the antenna bracket 13, but slightly larger. This ensures that the accommodating cavity has sufficient space for components such as the control circuit board 15, the antenna bracket 13, and the antenna, while also reducing the overall volume of the control box 10.

[0064] In some embodiments, the top shell 12 has a first slanted wall 125, and the first slanted wall 125 is spaced apart and arranged opposite to the first mounting surface 1321. Optionally, the first slanted wall 125 and the first mounting surface 1321 can be substantially parallel, so that when the control box 10 is mounted on the two-wheeled vehicle, the angle of the positioning antenna 141 can be determined by observing the angle of the first slanted wall 125. Figure 1 and Figure 9 An information carrier 126 is provided on the first inclined wall 125. The information carrier 126 is a machine-readable mark such as a QR code or a bar code, which is used for users to scan with a smart terminal to identify and use the two-wheeled vehicle.

[0065] Refer again Figure 11 The inner surface of the top shell 12 is provided with multiple reinforcing ribs 124. The number and location of these ribs 124 can be selected based on the required structural strength of each part of the top shell 12 to ensure that the required structural strength is met. At least one rib 124 is positioned opposite the antenna bracket 13, and a certain gap is provided between the rib 124 and the antenna mounted on the antenna bracket 13 to prevent compression of the positioning antenna 141, the short-range communication antenna 142, or other antennas, which could affect their performance. This also allows for deformation of the top shell 12 in the event of impact or temperature fluctuations.

[0066] The embodiment of the present invention further provides a two-wheeled vehicle, which can be used in the application scenario of shared vehicles. The two-wheeled vehicle can be in the form of a bicycle, an electric bicycle or other two-wheeled vehicles. Figure 12 The structure of the two-wheeled vehicle of this embodiment is schematically shown. Figure 12 The two-wheeled vehicle includes a vehicle body, which includes a frame 20 and two wheels 30 rotatably arranged on the frame 20, the two wheels being a front wheel and a rear wheel. Figures 1 to 11 In at least some of the embodiments described herein, the control box 10 is disposed on the vehicle body, for example, it may be mounted at a predetermined position on the vehicle frame 20 .

[0067] When the control box 10 is mounted on the vehicle frame 20, the radiation surface of the positioning antenna 141 faces upward or obliquely upward to ensure the positioning accuracy of the control box 10. For example, the first oblique wall 125 of the top shell 12 is substantially parallel to the radiation surface of the positioning antenna 141 disposed on the first mounting surface 1321 of the antenna bracket 13. Figure 10 , the first inclined wall 125 faces the upper rear of the two-wheeled vehicle, so it can be seen that the positioning antenna 141 also faces the upper rear of the two-wheeled vehicle. Optionally, the short-range communication antenna 142 faces the rear of the two-wheeled vehicle and is substantially parallel to the axle of the rear wheel of the two-wheeled vehicle, for example, referring to Figure 12 The short-range communication antenna 142 is perpendicular to the drawing and slightly downward toward the rear of the two-wheeled vehicle. Optionally, the mobile communication antenna 143 can be oriented toward the side of the two-wheeled vehicle to separate and stagger the short-range communication antenna 142 and the positioning antenna 141 to reduce signal interference.

[0068] The control box 10 is used to implement signal exchange between the two-wheeled vehicle and external devices (such as a server and / or user terminal) and control other devices on the two-wheeled vehicle. The two-wheeled vehicle also includes a lock body 40 for locking the two-wheeled vehicle. The lock body 40 locks the two-wheeled vehicle by locking the wheels 30, the frame 20, or other means. In some application scenarios, the lock body 40 and the control box 10 are respectively arranged at different positions on the frame 20. The control box 10 and the lock body 40 are spaced apart and communicated with each other via a wired or wireless manner. Signals are exchanged between the control box 10 and the lock body 40 to enable the control box 10 to control the lock body 40 and obtain its status.

[0069] The frame 20 includes a center tube 21, which is used to mount a seat tube. In some embodiments, the frame 20 also includes a fixing base 22 fixed to the rear side of the center tube 21, and the fixing base 22 is inclined rearward and downward from the center tube 21. The control box 10 is fixed to the fixing base 22. For example, the protective shell 18 can be connected to the fixing base 22 via a fourth connecting structure 184. The end surfaces of the bottom shell 11 and the fixing base 22 are substantially parallel, and the angle between the first mounting surface 1321 and the fixing base 22 is substantially equal to the first angle between the first mounting surface 1321 and the bottom shell 11. Optionally, the angle between the radiation surface of the positioning antenna 141 and the horizontal plane can be between 10° and 20°, which can avoid the seat cushion on the seat tube and achieve a better positioning effect for the positioning antenna 141. The fixing base 22 can also have a receiving groove for accommodating the protrusion 115 of the bottom shell 11 to protect the protrusion 115.

[0070] In one embodiment, the fixing base 22 is made of a metal material. For example, the fixing base 22 can be a metal casting or a metal stamping, and can be fixed to the middle tube 21 by welding. With this arrangement, on the one hand, a certain distance is maintained between the fixing base 22 and the antenna on the antenna bracket 13, which can act as a reflector and improve the antenna's radiation effect. For example, because the fixing base 22 is located below the positioning antenna 141, the signal transmission and reception capabilities of the positioning antenna 141 can be enhanced. On the other hand, it also helps to improve the structural strength of the fixing base 22 and ensure the installation stability of the control box 10.

[0071] The present invention provides a control box 10 and a two-wheeled vehicle. An antenna bracket 13 is provided within the control box 10. A raised portion 132 of the antenna bracket 13 includes a first mounting surface 1321, a second mounting surface 1322, and a third mounting surface 1323, each of which is arranged at an angle relative to the other. A positioning antenna 141 is positioned on the first mounting surface 1321, a short-range communication antenna 142 is positioned on the second mounting surface 1322, and a mobile communication antenna 143 is positioned on the third mounting surface 1323. The angle of the first mounting surface 1321 is such that, when the control box 10 is mounted on the two-wheeled vehicle, the positioning antenna 141 faces upward, facilitating satellite positioning search speed and accuracy. Furthermore, the antenna bracket 13 allows the positioning antenna 141, short-range communication antenna 142, and mobile communication antenna 143 to face different directions, thereby minimizing signal interference among the positioning antenna 141, short-range communication antenna 142, and mobile communication antenna 143, thereby ensuring effective signal transmission and reception for each antenna.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to fall within the scope of protection of the present invention.
