Abstract
Description
Technical Field
[0001] This invention relates to the technical field of vehicle accessories, and in particular to a clamp-on carrying rack connection device that can be installed on a trailer ball at the rear of a vehicle. Such devices are mainly used to connect various vehicle carrying racks, such as bicycle racks, luggage racks, or other outdoor sports equipment racks. Background Technology
[0002] Most vehicle carrier racks currently on the market require an additional special bracket to be installed at the rear of the vehicle, and the installation process is cumbersome and time-consuming. Although some carrier racks can be directly installed on the vehicle's original tow hook, these products are usually complex in structure, making them inconvenient to install and prone to loosening during use, posing a safety hazard.
[0003] In addition, most existing carrying rack connection devices adopt a fixed design, which lacks flexibility. When it is necessary to open the rear compartment of the vehicle, the carrying rack often needs to be completely removed, causing many inconveniences in use. Even if some products have a rotating function, their rotating structure is often relatively fragile and lacks a reliable fixing mechanism, making them prone to shaking or deformation during use.
[0004] Furthermore, traditional carrying rack connectors typically require specialized tools to install or remove, which is quite inconvenient for the average user. Additionally, these connectors are often heavy, making them difficult to move and store, further complicating their use. Summary of the Invention
[0005] The purpose of this invention is to provide a clamp-type carrying rack connection device that can be quickly and securely installed on a trailer ball at the rear of a vehicle.
[0006] To achieve the above objectives, the present invention provides a ball-clamping carrying rack connection device, which can be connected to a trailer ball at the rear of a vehicle. It includes: a rotating arm bracket comprising: a first rotating arm with a trailer ball connecting seat at its bottom for connecting to the trailer ball; a second rotating arm, one end of which is rotatably connected to the first rotating arm, and the other end having a connecting seat, the top surface of which has a top abutment portion and several fixing holes on its sides; the first and second rotating arms being rotatably extended relative to each other to a preset angle; and a opposing connecting seat with a positioning crossbar, and several fixing holes on both sides of the opposing connecting seat for at least one fixing screw and one fixing pin to detachably pass through; wherein the opposing connecting seat abuts against the top abutment portion on the connecting seat via the positioning crossbar, and the fixing screw and the fixing pin pass through the fixing holes and the fixing holes respectively, thereby fixing the opposing connecting seat to the connecting seat.
[0007] In one embodiment, the opposing coupling includes two symmetrically arranged baffles, the fixing holes are formed on one side of the baffles, and the positioning crossbar is disposed between the two baffles, so that there is a gap between the two baffles. After the opposing coupling is connected to the coupling, the two baffles are respectively fixed to the outside of the coupling through the fixing screw and the fixing pin.
[0008] In one embodiment, the coupling seat further includes a fixed protrusion tube, which is tightly covered by the two baffles after the opposite coupling seat is connected to the coupling seat.
[0009] In one embodiment, the first rotating arm further includes a support leg that can rotate relative to the first rotating arm to a vertical or parallel position.
[0010] In one embodiment, the first rotating arm further includes a set of auxiliary pulleys located at the bottom.
[0011] In one embodiment, the second rotating arm further includes a fixing member disposed on a socket of the second rotating arm, and the first rotating arm is formed with a first through hole and the second rotating arm is formed with a second through hole. When the first rotating arm and the second rotating arm are closed relative to each other, the first through hole and the second through hole overlap, so that the fixing member can pass through the first through hole and the second through hole simultaneously.
[0012] In one embodiment, the preset angle is between 0 degrees and 180 degrees.
[0013] In one embodiment, the trailer ball connector includes a recessed port for accommodating the trailer ball.
[0014] In one embodiment, the opposing coupling can be detachably connected to a vehicle frame.
[0015] In one embodiment, the opposing coupling is integrally formed with a vehicle frame.
[0016] In one embodiment, the second rotating arm is provided with a hanging ring, and a transverse support extends from the bottom of one end of the first rotating arm. When the preset angle between the first rotating arm and the second rotating arm is 0 degrees, the transverse support can pass through the hanging ring, so that the first rotating arm is supported by the hanging ring.
[0017] In one embodiment, the support bracket further includes a first support tube, a second support tube, and a positioning member. The first support tube can be accommodated inside the second support tube. The outside of the first support tube is provided with a positioning hole, and the outside of the second support tube is provided with a positioning groove relative to the positioning hole. The positioning groove forms a plurality of positioning slots. Attached Figure Description

[0050] The terms "first" and "second," etc., used in the specification and accompanying drawings of this invention are for distinguishing different objects, not for describing a specific order. The invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0051] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0052] Please refer to Figure 1 The figure shows a three-dimensional structural schematic of the ball-clamping carrying rack connecting device 10 of the present invention. As shown, the ball-clamping carrying rack connecting device 10 mainly includes a rotating arm bracket 101 and a corresponding coupling seat 102. Normally, the rotating arm bracket 101 and the corresponding coupling seat 102 are integrated. The rotating arm bracket 101 includes a first rotating arm 1011 and a second rotating arm 1012, which are connected by a pivot joint. Please refer to the accompanying documentation. Figure 2 This is another schematic diagram of the ball-clamping carrying frame connection device, as shown below. Figure 2 As shown, the bottom of the first rotating arm 1011 is provided with a trailer ball connector 1013, which is used to connect with the trailer ball of a vehicle; please refer to the accompanying documentation. Figure 3 This is an exploded view of the components of the ball-clamping carrying frame connecting device, such as... Figure 3 As shown, the other end of the second rotating arm 1012 is provided with a connecting seat 1014, the top surface of the connecting seat 1014 is formed with a backing portion 1015, and the side of the connecting seat 1014 is provided with several fixing through holes 1016; please refer to the accompanying document. Figure 4 This is a schematic diagram of the unfolded swivel arm support (I), as shown below. Figure 4As shown, one end of the second rotating arm 1012 is rotatably connected to the first rotating arm 1011, meaning that the first rotating arm 1011 and the second rotating arm 1012 can rotate and open relative to each other, allowing the first rotating arm 1011 and the second rotating arm 1012 to rotate and unfold relative to each other to a preset angle A. The opening and closing angle state of the preset angle A is as follows: Figure 5 As shown, Figure 5 This is a schematic diagram (II) of the unfolded swivel arm support. Figure 4 and Figure 5 It is understood that the preset angle A of the first rotating arm 1011 and the second rotating arm 1012 constituting the rotating arm support 101 is between 0 degrees and 180 degrees, that is, the first rotating arm 1011 and the second rotating arm 1012 can be unfolded as follows: Figure 4 The 180-degree posture can also be like... Figure 5 The first rotating arm 1011 and the second rotating arm 1012 can rotate and unfold 90 degrees relative to each other, and of course, the first rotating arm 1011 and the second rotating arm 1012 can also be closed.
[0053] like Figure 3 and 4 As shown, the other end of the second rotating arm 1012 is provided with a connecting seat 1014. The top surface of the connecting seat 1014 is formed with a backing portion 1015, and the side of the connecting seat 1014 is provided with several fixing through holes 1016. One end of the second rotating arm 1012 is rotatably connected to the first rotating arm 1011, that is, the first rotating arm 1011 and the second rotating arm 1012 can rotate and open relative to each other, so that the first rotating arm 1011 and the second rotating arm 1012 can rotate and unfold relative to each other to a preset angle A. The opening and closing angle state of the preset angle A is as follows. Figure 5 As shown, by Figure 4 and Figure 5 It is understood that the preset angle A of the first rotating arm 1011 and the second rotating arm 1012 constituting the rotating arm support 101 is between 0 degrees and 180 degrees, that is, the first rotating arm 1011 and the second rotating arm 1012 can be unfolded as follows: Figure 4 The 180-degree posture can also be like... Figure 5 The first rotating arm 1011 and the second rotating arm 1012 can rotate and unfold 90 degrees relative to each other, and of course, the first rotating arm 1011 and the second rotating arm 1012 can also be closed.
[0054] Please see again Figures 1 to 3A positioning crossbar 1021 is provided near the top of the opposing coupling seat 102, and multiple fixing holes 1022 are provided on both sides of the opposing coupling seat 102. These fixing holes 1022 allow at least one fixing screw 1023 and a fixing pin 1024 to pass through detachably. When the rotating arm bracket 101 is to be engaged with the opposing coupling seat 102, the positioning crossbar 1021 of the opposing coupling seat 102 is pre-pressed against the abutment part 101 on the coupling seat 1014. 5. The positioning crossbar 1021 and the top abutment 1015 are pre-engaged to facilitate smoother assembly of subsequent components. When the positioning crossbar 1021 and the top abutment 1015 are pre-engaged, the fixing screws 1023 and fixing pins 1024 pass through the fixing holes 1022 and fixing through holes 1016 respectively for locking, thus fixing the opposing coupling seat 102 to the coupling seat 104 to form a single unit. The completed assembly is as follows: Figure 1 As shown.
[0055] Please see again Figure 3 In one embodiment, the opposing coupling seat 102 further includes two symmetrically arranged baffles (1025, 1025'). One side of each baffle (1025, 1025') has fixed holes 1022, and the positioning crossbar 1021 is disposed between the two baffles (1025, 1025'), creating a gap between them. After the opposing coupling seat 102 is engaged with the coupling seat 1014, the two baffles (1025, 1025') are fixed to the outside of the coupling seat 1014 via the fixing screws 1023 and the fixing pins 1024, respectively, so that the two baffles (1025, 1025') cover the outside of the coupling seat 1014 (e.g., ...). Figure 1 (As shown).
[0056] Please see again Figure 1 and Figure 3 In one embodiment, the coupling seat 1014 further includes a fixed protrusion tube 1017, which is a tube that protrudes laterally relative to the coupling seat 1014. After the relative coupling seat 102 and the coupling seat 1014 are coupled, the fixed protrusion tube 1017 is automatically engaged between the two baffles (1025, 1025') to be tightly covered by the two baffles (1025, 1025'). Its function is to reduce the gap generated between the coupling seat 1014 and the relative coupling seat 102 after coupling, avoid the swaying of the swivel arm bracket 101 and the relative coupling seat 102 after coupling, and increase the overall structural stability.
[0057] Please see Figures 6 to 9In one embodiment, the second rotating arm 1012 further includes a fixing member 103, which is disposed on a socket 10121 of the second rotating arm 1012. Normally, the fixing member 103 is assembled in the socket 10121 for easy access by the user. The first rotating arm 1011 has a first through hole 10111, and the second rotating arm 1012 has a second through hole 10122 relative to the first through hole 10111. When the first rotating arm 1011... When the first rotating arm 1011 and the second rotating arm 1012 are closed relative to each other (i.e., when the preset angle A is 0 degrees), the first through hole 10111 and the second through hole 10122 will be concentric and overlapped, allowing the user to lock the first rotating arm 1011 and the second through hole 10122 by passing the fastener 103 through the first through hole 10111 and the second through hole 10122 at the same time, thereby fixing the first rotating arm 1011 and the second rotating arm 1012 so that they cannot be unfolded, thus preventing the rotating arm bracket 101 from being unfolded at will when not in use, which would cause inconvenience.
[0058] Please see Figures 10 to 12 In one embodiment, the first rotating arm 1011 further includes a support leg 1018, which is fixed by a rotating member 10181, so that the support leg 1018 is rotatably coupled to the first rotating arm 1011. The support leg 1018 can rotate relative to the first rotating arm 1011 to a vertical or parallel position. Under normal conditions, when not in use, the support leg 1018 is stored parallel to the first rotating arm 1011 (e.g., ...). Figure 2 (As shown); When the support leg 1018 is to be placed on the ground, the rotating part 10181 is first loosened by rotation, and the direction of loosening is as follows: Figure 10 As indicated by the arrow, at this point, the support leg 1018 can function as... Figure 11 As shown, it moves further forward and rotates to stand on the ground, so that the support leg 1018 can be perpendicular to the first rotating arm 1011, and the support leg 1018 stands on the ground as shown. Figure 12 As shown, by Figure 12 It is understood that when the first rotating arm 1011 and the second rotating arm 1012 are extended, they are supported on the ground by the support leg 1018, which can effectively provide sufficient support for the first rotating arm 1011 and the second rotating arm 1012, and prevent the rotating arm support 101 from tipping over when it is extended.
[0059] Please refer to the following: Figure 13 and Figure 14In one embodiment, the support bracket 1018 further includes a first support tube 10182, a second support tube 10183, and a positioning member 10184. The diameter of the first support tube 10182 is smaller than the inner diameter of the second support tube 10183, so that the first support tube 10182 can be accommodated in the internal space of the second support tube 10183, allowing the first support tube 10182 and the second support tube 10183 to extend and retract relative to each other. Furthermore, the outside of the first support tube 10182 is provided with a positioning hole 10185, and the outside of the second support tube 10183 is provided with a positioning groove 10186 relative to the positioning hole 10185. The positioning groove 10186 forms a plurality of positioning slots 10187 arranged sequentially and at equal distances, and these positioning slots 10187 are interconnected. The positioning element 10184 has a positioning rod 10188 and at least one positioning protrusion 10189 that can correspondingly engage with the positioning slot 10187, and preferably, the number of positioning protrusions 10189 is two. Figure 13 and Figure 14 It can be seen that when the positioning member 10184 is combined with the second support tube 10183, the positioning rod 10188 can be inserted into the positioning hole 10185, and the positioning protrusion 10189 can be inserted into the positioning slot 10187, so that the positioning member 10184 is combined with the outside of the second support tube 10182, and the combined state is as follows. Figure 12 As shown. Please also refer to... Figure 13 and Figure 14 When the first support tube 10182 and the second support tube 10183 of the support bracket 1018 are to be extended or retracted, since the positioning member 10184 is normally fixed to the outside of the second support tube 10183, the positioning protrusion 10189 of the positioning member 10184 must be disengaged from the positioning slot 10187 of the second support tube 10183 beforehand. However, the positioning rod 10188 is still inserted in the positioning hole 10185 of the first support tube 10182. At this time, the second support tube 10183 can be extended or retracted according to the user's required height. The length of the first support tube 10182 can be adjusted vertically, or the height of the first support tube 10182 can be adjusted vertically relative to the second support tube 10183. This is not a limitation. After determining the adjustment length, the positioning protrusion 10189 of the positioning member 10184 is then engaged into one of the positioning slots 10187, so that the second support tube 10183 is fixed by the positioning member 10184. The states of the first support tube 10182 and the second support tube 10183 before and after height adjustment are as follows: Figure 15 and Figure 16 As indicated by the arrow in the figure, the first support tube 10182 and the second support tube 10183 can adjust the overall length of the support leg 1018 after relative extension and retraction.
[0060] Please see again Figure 2 In one embodiment, the first rotating arm 1011 further includes a set of auxiliary pulleys 1019 located at the bottom. The auxiliary pulleys 1019 can be used to move the entire ball-clamping carrying frame connection device 10 by pushing, so that the user can install the ball-clamping carrying frame connection device 10.
[0061] Please see Figure 17 The figure shows a schematic diagram of the connection between the relative coupling seat 102 and the vehicle carrier frame. As shown, the relative coupling seat 102 can be detachably connected to a vehicle carrier frame 13, or the relative coupling seat 102 can be integrally formed with the vehicle carrier frame 13. Furthermore, the relative coupling seat 102 can be connected to or assembled with any type of external device, such as a trailer, etc., without limitation. After the relative coupling seat 102 is connected to the vehicle carrier frame 13, it can be assembled with the swing arm bracket 101.
[0062] Please see again Figures 18 to 19 ,like Figure 18 As shown, the trailer ball connector 1013 includes a connector 10131, which is recessed to accommodate a trailer ball 11 located at the rear of a vehicle 12. The trailer ball 11 is spherical and is normally connected to the rear of the vehicle 12, protruding from the rear end of the vehicle 12 chassis. Following this, after the trailer ball connector 1013 accommodates the trailer ball 11 through the connector 10131, the trailer ball connector 1013 can then be operated to tighten the trailer ball 11. Please refer to [further details omitted]. Figure 16 After the trailer ball connector 1013 and the trailer ball 11 are connected, it is as follows: Figure 20 As shown, the ball-clamp carrying rack connecting device 10 and the vehicle carrying rack 13 are normally fixed to the rear of the vehicle 12. When the user wants to open the rear compartment of the vehicle 12, the first rotating arm 1011 and the second rotating arm 1012 can be extended to the desired preset angle A, for example... Figure 21 As shown, the preset angle A of the first rotating arm 1011 and the second rotating arm 1012 is 90 degrees to facilitate the user's access to items in the trunk of the vehicle 12. The first rotating arm 1011 and the second rotating arm 1012 can also be... Figure 22 As shown, the preset angle A of the unfolded shape is 180 degrees.
[0063] Please see Figure 6 and Figure 23The second rotating arm 1012 is provided with a hanging ring 10123. When the preset angle A of the first rotating arm 1011 and the second rotating arm 1012 is 0 degrees, a horizontal support 10112 extending from the bottom of one end of the first rotating arm 1011 can pass through the hanging ring 10123, so that the first rotating arm 1011 and the second rotating arm 1012 can achieve a tight fit. This prevents the gap between the first rotating arm 1011 and the second rotating arm 1012 from becoming larger and larger due to external vibration or other forces when folding, thus avoiding damage.
[0064] Please see Figures 24 to 26 The relative coupling seat 102 of the present invention can be combined with the coupling seat 1014 in different orientations, and the assembled state is as follows. Figure 24 and Figure 25 As shown, the assembled state of the relative coupling seat 102 and the coupling seat 1014 is different from that shown. Figure 2 The relative coupling seat 102 and the coupling seat 1014 are assembled in the form of... Figure 24 The assembly method mainly allows the car carrier frame 13 to be upright relative to the ball-type car carrier connecting device 10, and the upright state of the car carrier frame 13 is as follows: Figure 26 As shown, the bicycle rack 13 is designed to facilitate storage when not in use, thus avoiding any impact on driving safety.
[0065] Please see Figures 27 to 30 As shown in the figure, the bicycle carrier 13 is equipped with a warning module 131, and the warning module 131 is movably connected to a corresponding connecting frame 133 of the bicycle carrier 13 body through a connecting frame 132. The connecting frame 132 is provided with a first fixing hole 1321, while the corresponding connecting frame 133 is provided with a second fixing hole 1331 and a third fixing hole 1332. Figure 27 and Figure 28 As shown, the connecting frame 132 and the opposing connecting frame 133 are connected by a shaft 134, allowing the connecting frame 132 and the opposing connecting frame 133 to rotate relative to each other. A fixing rod 135 can also limit the movement between the connecting frame 132 and the opposing connecting frame 133. Figure 26 As shown, the fixing rod 135 can pass through the first fixing hole 1321 and the second fixing hole 1331 to form a first mode between the connecting bracket 132 and the opposing connecting bracket 133. This first mode is mainly used when the vehicle is in motion. For example... Figure 27As shown, the fixing rod 135 can also be removed, allowing the warning module 131 to rotate downwards relative to the body of the vehicle carrier 13 to form a second mode. The fixing rod 135 is then passed through the first fixing hole 1031 and the third fixing hole 1332 for fixation, preventing the connecting frame 132 and the opposing connecting frame 133 from rotating relative to each other due to the fixing rod 135. See also... Figure 28 and Figure 29 The bottom of the carrying frame 13 is provided with a fixed long screw 135 that can move back and forth. One end of the fixed long screw 135 is formed with a threaded section 1351, while the other end is exposed in the second mode. Please refer to the accompanying documentation. Figures 6 to 9 as well as Figures 29 to 30 When the first through hole 10111 and the second through hole 10122 are concentric and overlap, the user can rotate the end of the fixed long screw 135 away from the threaded section 1035 in the second mode, so that the threaded section 1351 of the fixed long screw 135 can pass through the first through hole 10111 and the second through hole 10122 at the same time to complete the locking, thereby fixing the first rotating arm 1011 and the second rotating arm 1012 so that they cannot be unfolded, thus avoiding the inconvenience caused by the rotating arm bracket 101 being arbitrarily unfolded when combined with the vehicle frame 13.
[0066] In summary, this invention provides an intelligent power monitoring and automatic charging management system and method. Through the coordinated operation of the vehicle controller, automatic voltage detection system, power distribution system, and high-voltage power supply conversion system, it realizes real-time monitoring and automatic charging management of the battery system, improves the efficiency and reliability of the vehicle power system, and takes into account user experience and safety. This proves that this invention can effectively improve the problem of conventional battery systems running out of power, and meets the requirements for an invention patent application.
