Description

Technical Field

[0001] This utility model relates to the field of vehicle-related technology, and more specifically, to a ball bag car. Background Technology

[0002] In existing golf cart designs, the way the cart follows the player typically relies on visual recognition systems or fixed-position wireless positioning technologies, such as capturing player location information via cameras or using Ultra-Wide Band (UWB) positioning technology. While visual recognition methods are intuitive and accurate, their effectiveness is greatly limited by environmental factors. For example, on a golf course, factors such as vegetation obstruction, changes in lighting, and weather conditions can cause cameras to fail to continuously track players, especially when the player is behind or to the side of the cart. Furthermore, camera systems are costly to maintain and require regular cleaning to ensure their performance.

[0003] On the other hand, using fixed UWB base stations for location detection also has significant limitations. UWB technology, due to its high accuracy and low latency, shows great potential in golf cart following scenarios. However, when a UWB base station is fixed to the golf cart, its scanning range is limited, generally only covering a fan-shaped area at a certain angle in front of the cart (usually 60° to the left and right of the cart's centerline). Once the player moves out of this range, the base station cannot detect the UWB tag on the player, resulting in loss of the tracking target and thus interrupting the golf cart's following function.

[0004] As a result, existing ball bag car following systems face the problem of frequent target loss due to visual obstruction or limited wireless signal reception range. This not only reduces the reliability of ball bag car following but also seriously affects the user experience. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a ball bag car.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A ball-shaped vehicle includes a frame and a position detection device. The position detection device includes a circuit board, a rotating mechanism, and a base station. The circuit board is mounted on the frame. The rotating mechanism includes a fixed part and a rotating part rotatably mounted on the fixed part. The fixed part is disposed on the surface of the circuit board. The base station is disposed on the rotating part and rotates with the rotating part. The base station is used to acquire the position information of the object to be detected. Both the rotating mechanism and the base station are electrically connected to the circuit board. This application uses a base station set on the circuit board to realize position information detection. By setting a rotating mechanism between the circuit board and the base station, the base station can rotate with the rotating mechanism. The rotating base station can expand the detection range, avoid the occurrence of detection blind spots, and thus improve the accuracy of position detection of the ball-shaped vehicle, which is beneficial to improving the user experience.

[0008] In some embodiments, the base station is disposed on the end face of the rotating part away from the circuit board, and the base station has a base station antenna surface disposed vertically. This application disposes the base station on the end face of the rotating part away from the circuit board, avoiding interference from the rotation mechanism during position detection, thereby improving the accuracy of base station position detection. Furthermore, this application uses a vertically disposed base station antenna surface, which helps optimize the directionality of signal reception and transmission, improving base station detection accuracy.

[0009] In some embodiments, the end face of the rotating part away from the circuit board is parallel to the circuit board; and / or the end face of the rotating part away from the circuit board is parallel to the horizontal plane, and the base station antenna surface is perpendicular to the end face of the rotating part away from the circuit board. The rotating part in this application has its end face parallel to the circuit board, thus providing a support surface for the base station installation and improving the stability of the base station installation; the rotating part in this application has its end face parallel to the horizontal plane, which allows the circuit board to be set vertically, facilitating installation and fixation, and improving the accuracy and reliability of position detection.

[0010] In some embodiments, the position detection device further includes a connector. The base station is fixedly connected to the rotating part via the connector. The connector includes a first plate segment and a second plate segment. The first plate segment is disposed on the end face of the rotating part away from the circuit board. The second plate segment is bent from the first plate segment. The base station is connected to the second plate segment and is in contact with at least a portion of the second plate segment. The base station is connected to the rotating part via the connector, which facilitates the assembly and disassembly of the base station, improving the flexibility of use. The connector also improves the stability of the base station installation. Specifically, the bent structure of the first and second plate segments allows for the positioning of the base station and the rotating part while ensuring that the antenna surface of the base station is vertically aligned, unaffected by the rotating part, thereby improving the accuracy of the base station's position detection.

[0011] In some embodiments, a clearance area is formed at the center of the circuit board surface, and the fixing part is disposed in the clearance area. The clearance area in this application is used to provide installation space. By disposing the fixing part of the rotating mechanism in the clearance area, it is beneficial to increase the stability of the rotating mechanism's positioning and installation. The setting of the clearance area avoids interference from other electronic components on the circuit board to the rotating mechanism, thereby improving the integration and functional stability of the device.

[0012] In some embodiments, the circuit board has multiple positioning holes, and the position detection device further includes fasteners that pass through the positioning holes. The circuit board is connected to the fixing part through the fasteners. This application uses fasteners to enable the fixing part to be detachably mounted on the circuit board, which improves the flexibility of the structural arrangement and also ensures the stability of the connection between the fixing part and the circuit board.

[0013] In some embodiments, the rotating mechanism further includes a drive component electrically connected to the circuit board. The drive component is disposed on the fixed portion, and its drive end is drivenly connected to the rotating portion. The drive component provides driving force for the rotating portion to rotate in a first direction and a second direction opposite to the rotation direction. The principle of this design is that the use of the drive component provides power to the rotating mechanism, ensuring that the base station can quickly and accurately adjust its orientation to be suitable for detecting position information at different locations.

[0014] In some embodiments, the rotating mechanism is a gimbal; and / or the fixed part and the rotating part are coaxial cylindrical structures, with the base station disposed on the end face of the rotating part away from the circuit board, and the axes of the base station and the rotating mechanism are spaced apart and parallel. The rotating mechanism of this application can be a gimbal, which drives the base station to rotate omnidirectionally, thereby adjusting the position of the base station and improving the accuracy of base station detection; simultaneously, the cylindrical fixed part and rotating part structure facilitates the rotating part to drive the base station to rotate omnidirectionally under the action of the driving component, making the base station suitable for position detection at all angles.

[0015] In some embodiments, the position detection device further includes a base plate and a housing. The base plate is fixedly mounted on the vehicle frame, and the housing is detachably mounted on the base plate. The base plate and housing cooperate to form a sealed protective cavity. The circuit board, rotating mechanism, and base station are disposed inside the protective cavity, and the circuit board is detachably mounted on the base plate. This application uses a base plate and housing to form a sealed protective cavity to protect the circuit board, rotating mechanism, and base station inside the protective cavity from the influence of external environmental factors, making it suitable for different usage environments and improving the stability of the circuit board, rotating mechanism, and base station in use.

[0016] In some embodiments, the vehicle also includes two pairs of wheels arranged in a pair, with the two wheels respectively disposed on both sides of the frame. The position detection device is located on the central axis of the frame, perpendicular to the line connecting the centers of the two wheels. By placing the position detection device on the central axis of the frame, this application optimizes the layout of the device, thereby ensuring that the base station can perform real-time position detection around the frame and ensuring the accuracy and stability of the position detection.

[0017] This utility model has the following beneficial effects:

[0018] This application uses a base station set on a circuit board to detect position information. By setting a rotating mechanism between the circuit board and the base station, the base station can rotate with the rotating mechanism. The rotating base station can expand the detection range, avoid the occurrence of detection blind spots, and thus improve the accuracy of the ball bag car's position detection, which is conducive to improving the user experience.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0033] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0034] To address the frequent target loss issues in existing ball bag car following systems caused by visual obstruction or limited wireless signal reception range, which not only reduces the reliability of ball bag car following but also seriously affects the user experience, this utility model provides a ball bag car.

[0035] like Figure 1 As shown, the golf bag vehicle includes a frame 10 and a position detection device, wherein the position detection device is mounted on the frame 10 and is used to acquire the position information of the object to be detected, such as the position information of a player on a golf course.

[0036] Specifically, the ball bag car also includes two pairs of running wheels 20, which are respectively set on both sides of the frame 10. The line connecting the central axis of the frame 10 and the center of the two running wheels 20 is perpendicular, and the position detection device is located on the central axis.

[0037] In this embodiment, by placing the position detection device on the central axis of the frame 10, the layout of the device is optimized, thereby ensuring that the base station 330 can perform real-time position detection around the frame 10 and ensuring the accuracy and stability of the position detection. The line connecting the central axis of the frame 10 and the centers of the two wheels 20 intersects in an area. The position detection device can be located at this intersection or outside the intersection. In this application, the position detection device is located in the area between the wheels 20 and the handlebars of the frame 10.

[0038] like Figures 2 to 4 As shown, the position detection device includes a circuit board 310, a rotating mechanism 320, and a base station 330. The circuit board 310 is mounted on the vehicle frame 10, and the base station 330 is mounted on the circuit board 310 via the rotating mechanism 320. The rotating mechanism 320 enables the base station 330 to rotate relative to the circuit board 310. The base station 330 can achieve omnidirectional detection through rotation to obtain the position information of the object to be detected.

[0039] The use of base station 330 can avoid the problem in existing technologies where cameras are blocked by grass, mud, etc., during location detection, resulting in the inability to detect the location information of the object to be detected.

[0040] Specifically, the rotating mechanism 320 includes a fixed part 321 and a rotating part 322 rotatably disposed on the fixed part 321. The fixed part 321 is disposed on the surface of the circuit board 310. The base station 330 is disposed on the rotating part 322 and rotates with the rotating part 322. The base station 330 is used to acquire the position information of the object to be detected. The rotating mechanism 320 and the base station 330 are both electrically connected to the circuit board 310. The position information acquired by the base station 330 is fed back to the circuit board 310. The circuit board 310 controls the base station 330 to detect the position information of the object to be detected. The circuit board 310 controls the rotating mechanism 320 to rotate, thereby driving the base station 330 to rotate.

[0041] This application uses a base station 330 set on a circuit board 310 to detect position information. By setting a rotating mechanism 320 between the circuit board 310 and the base station 330, the base station 330 can rotate with the rotating mechanism 320. The rotating base station 330 can expand the detection range, avoid the occurrence of detection blind spots, and thus improve the accuracy of the ball bag car's position detection, which is conducive to improving the user experience.

[0042] In this embodiment, the rotating mechanism 320 is disposed on the surface of the circuit board 310, and an avoidance area 311 is formed at the center of the surface of the circuit board 310, and the fixing part 321 is disposed in the avoidance area 311.

[0043] The clearance area 311 in this application is used to provide installation space. By setting the fixing part 321 of the rotating mechanism 320 in the clearance area 311, it is beneficial to increase the stability of the positioning and installation of the rotating mechanism 320. The setting of the clearance area 311 avoids interference from other electronic components on the circuit board 310 to the rotating mechanism 320, and improves the integration and functional stability of the device.

[0044] like Figure 3 and Figure 4 As shown, the circuit board 310 has multiple positioning holes, and the position detection device also includes fasteners that pass through the positioning holes. The circuit board 310 is connected to the fixing part 321 through the fasteners.

[0045] The fasteners are set one-to-one with the positioning holes. The number of positioning holes can be 2, 3, 4, 5, 6, etc. The specific number and setting position can be adapted according to the actual scenario.

[0046] Fasteners can be structural components such as screws, and the circuit board 310 and the fixing part 321 are fixed by screws.

[0047] Specifically, this application uses fasteners to make the fixing part 321 detachably mounted on the circuit board 310, which improves the flexibility of the structural setup and also ensures the stability of the connection between the fixing part 321 and the circuit board 310.

[0048] Of course, it is not limited to using fasteners to achieve a detachable connection between the fixing part 321 and the circuit board 310. It can also be fixed by snap-fitting. For example, a slot can be provided on one of the fixing part 321 and the circuit board 310, and a buckle can be provided on the other. The detachable connection can be achieved by the snap-fitting structure of the slot and the buckle.

[0049] In this embodiment, the detachable connection described above is not limited to the method of bonding; the fixing part 321 can also be fixedly disposed on the circuit board 310 by means of bonding or other methods.

[0050] like Figure 3 and Figure 4 As shown, the base station 330 is disposed on the end face of the rotating part 322 that is away from the circuit board 310.

[0051] This application places the base station 330 on the end face of the rotating part 322 away from the circuit board 310, which avoids the problem of the rotating mechanism 320 interfering with the position detection during the position detection process of the base station 330, thereby improving the accuracy of the position detection of the base station 330.

[0052] In this embodiment, the end face of the rotating part 322 facing away from the circuit board 310 is parallel to the circuit board 310. The rotating part 322 adopted in this application has an end face facing away from the circuit board 310 that is parallel to the circuit board 310, thereby providing a support surface for the installation of the base station 330 and improving the stability of the installation of the base station 330.

[0053] In this embodiment, the base station 330 has a base station antenna surface 331, which is arranged in a vertical direction.

[0054] In this application, the base station antenna surface 331 is set vertically, which is beneficial to optimize the directionality of signal reception and transmission and improve the detection accuracy of base station 330.

[0055] Specifically, the end face of the rotating part 322 away from the circuit board 310 is parallel to the horizontal plane, and the base station antenna surface 331 is perpendicular to the end face of the rotating part 322 away from the circuit board 310.

[0056] The rotating part 322 of this application has its end face away from the circuit board 310 parallel to the horizontal plane. This allows the circuit board 310 to be set vertically, which facilitates installation and fixation, and helps to improve the accuracy and reliability of position detection.

[0057] like Figure 3 and Figure 4 As shown, the position detection device also includes a connector 340, through which the base station 330 is connected to the rotating part 322.

[0058] The base station 330 is connected to the rotating part 322 via the connector 340, which ensures a stable connection between the base station 330 and the rotating mechanism 320, while facilitating the installation and disassembly of the base station 330 and improving the maintainability and flexibility of the device.

[0059] Specifically, the connector 340 includes a first plate segment 341 and a second plate segment 342. The first plate segment 341 is disposed on the end face of the rotating part 322 away from the circuit board 310. The second plate segment 342 is bent and disposed with the first plate segment 341. The base station 330 is connected to the second plate segment 342 and is in contact with at least a portion of the second plate segment 342.

[0060] The first plate segment 341 and the second plate segment 342 are both plate structures. The first plate segment 341 and the end face of the rotating part 322 form a surface-to-surface fit structure, which helps to increase the contact area and thus improve the stability of the structure installation. The surface-to-surface fit structure between the second plate segment 342 and the base station 330 helps to increase the contact area and thus improve the stability of the structure installation.

[0061] The first plate segment 341 and the end face of the rotating part 322 are positioned and connected by fasteners such as bolts, and the second plate segment 342 and the base station 330 are positioned and connected by fasteners such as bolts.

[0062] The connector 340 of this application includes a first plate segment 341 and a second plate segment 342 with a bent structure. Specifically, the first plate segment 341 and the second plate segment 342 are arranged vertically, the first plate segment 341 is arranged in the horizontal direction, and the second plate segment 342 is arranged in the vertical direction.

[0063] The connector 340 of this application can locate the base station 330 and the rotating part 322, and at the same time, it can make the antenna surface of the base station 330 vertically set, unaffected by the rotating part 322, thereby improving the position detection accuracy of the base station 330.

[0064] In this embodiment, the rotating mechanism 320 can be a gimbal, which drives the base station 330 to rotate in all directions, thereby adjusting the position of the base station 330 and improving the detection accuracy of the base station 330.

[0065] like Figure 3 and Figure 4 As shown, the rotating part 322 of the rotating mechanism 320 is disposed on the side of the fixed part 321 away from the circuit board 310 and can be rotatably connected to the fixed part 321.

[0066] Specifically, the rotating mechanism 320 also includes a drive component electrically connected to the circuit board 310. The drive component is disposed on the fixed part 321, and its drive end is drivenly connected to the rotating part 322. The drive component provides driving force for the rotating part 322 to rotate in a first direction and a second direction opposite to the rotation direction. The principle of this design is that by using the drive component, power is provided to the rotating mechanism 320, ensuring that the base station 330 can quickly and accurately adjust its direction to be suitable for detecting position information at different locations.

[0067] The driving component can be a motor.

[0068] In this embodiment, the driving component can drive the rotating part 322 to rotate in two directions, which is beneficial for rapid positioning. Furthermore, this application uses a driving component to drive the rotating part 322 to rotate. The driving component can drive the rotating part 322 to rotate 180°, 360°, 720°, etc., in either the first or second direction. The specific angle can be adaptively set as needed; that is, the rotation angle range of the rotating part 322 in this application can be greater than 360°. In this embodiment, when the position detection device is triggered to detect the position information of the object to be detected, the rotating part 322, under the action of the driving component, drives the base station 330 to rotate on the horizontal plane, for example, by 360°, to detect the position of the object to be detected and feed the position information back to the circuit board 310.

[0069] like Figure 3 and Figure 4 As shown, the fixed part 321 and the rotating part 322 are coaxial cylindrical structures.

[0070] This application adopts a cylindrical fixed part 321 and a rotating part 322 structure, which facilitates the rotating part 322 to drive the base station 330 to rotate in all directions under the action of the driving member, so that the base station 330 is suitable for position detection at all angles.

[0071] Specifically, the base station 330 is disposed on the end face of the rotating part 322 away from the circuit board 310, and the axes of the base station 330 and the rotating mechanism 320 are spaced apart and parallel.

[0072] In this embodiment, the base station 330 and the rotating mechanism 320 are spaced apart and arranged in parallel so that the base station antenna surface 331 of the base station 330 can be close to the edge of the rotating part 322, so as to better detect the environment and improve the detection accuracy and stability.

[0073] In this embodiment, the position detection device further includes a base plate 350 and a housing 360. The base plate 350 is fixedly mounted on the vehicle frame 10, and the housing 360 is detachably mounted on the base plate 350. The base plate 350 and the housing 360 cooperate to form a sealed protective cavity. The circuit board 310, the rotating mechanism 320 and the base station 330 are disposed inside the protective cavity, and the circuit board 310 is detachably mounted on the base plate 350.

[0074] This application uses a base plate 350 and a housing 360 to form a sealed protective cavity to protect the circuit board 310, rotating mechanism 320 and base station 330 inside the protective cavity from the influence of external environmental factors, so as to be suitable for different usage environments, and at the same time improve the stability of the use of the circuit board 310, rotating mechanism 320 and base station 330.

[0075] The base plate 350 can be installed onto the frame 10 using bolts or other fasteners to facilitate independent assembly and disassembly of the base plate 350.

[0076] In this embodiment, the outer casing 360 and the base plate 350 are detachably connected by fasteners such as snap-fit ​​or bolts, which facilitates the separation of the outer casing 360 from the base plate 350 when modifying or repairing or replacing the base station 330, the circuit board 310 and the rotating mechanism 320.

[0077] This utility model has the following beneficial effects:

[0078] This application uses a base station 330 set on a circuit board 310 to detect position information. By setting a rotating mechanism 320 between the circuit board 310 and the base station 330, the base station 330 can rotate with the rotating mechanism 320. The rotating base station 330 can expand the detection range, avoid the occurrence of detection blind spots, and thus improve the accuracy of the ball bag car's position detection, which is conducive to improving the user experience.
