Description

Technical Field

[0001] This application relates to the field of automotive parts, and in particular to a movable loading device and trunk system. Background Technology

[0002] In some vehicles (such as SUVs, RVs, or MPVs), a movable loading device may be installed at the bottom of the trunk to assist users in accessing items. The bottom of the trunk typically also includes storage compartments for items such as spare tires and tools. In existing technology, the presence of this movable loading device can hinder users' ability to access items in the storage compartments. Utility Model Content

[0003] This application provides a movable loading device and a trunk system that can solve the technical problem in the prior art where the setting of the movable loading device affects the user's ability to retrieve and place items in the storage compartment.

[0004] To solve the above-mentioned technical problems, in a first aspect, this application adopts a technical solution as follows: providing a movable loading device for use in a trunk system, comprising: a base assembly; a drive assembly fixed to the base assembly; a support frame assembly drivenly connected to the drive assembly, wherein the support frame assembly is movable relative to the base assembly under the drive of the drive assembly; and a loading tray assembly for loading items, wherein the loading tray assembly is disposed on the support frame assembly and hinged to the support frame assembly, so that the loading tray assembly can move with the support frame assembly and can be flipped relative to the support frame assembly.

[0005] In some embodiments, the movable loading device further includes a support rod, one end of which is connected to the support frame assembly and the other end of which is connected to the loading tray assembly; wherein, driven by the support rod, the loading tray assembly is capable of rotating relative to the support frame assembly.

[0006] In some embodiments, the strut is an electric strut.

[0007] In some embodiments, the movable loading device further includes a first mounting bracket and a second mounting bracket, the first mounting bracket being fixed to the tray assembly, the second mounting bracket being fixed to the loading tray assembly, one end of the support rod being ball-jointed to the first mounting bracket, and the other end of the support rod being ball-jointed to the second mounting bracket.

[0008] In some embodiments, the movable loading device further includes a balance bar, one end of which is connected to the support frame assembly and the other end of which is connected to the loading tray assembly. In a first direction, the balance bar and the support rod are spaced apart. The balance bar can assist the support rod in opening or closing the loading tray assembly, and the loading tray assembly can be suspended under the action of the balance bar.

[0009] In some embodiments, the balance bar is a gas spring.

[0010] In some embodiments, the movable loading device further includes a third mounting bracket and a fourth mounting bracket, the third mounting bracket being fixed to the support frame assembly, the fourth mounting bracket being fixed to the loading tray assembly, one end of the balance bar being ball-jointed to the third mounting bracket, and the other end of the balance bar being ball-jointed to the fourth mounting bracket.

[0011] In some embodiments, the movable loading device further includes a limiting block and a locking rod. The limiting block is fixed to the base assembly, and the locking rod includes a locking hook, a first hinge, and a first operating part. The first hinge is connected between the locking hook and the first operating part and is hinged to the tray assembly. When the loading tray assembly is not rotated relative to the tray assembly, the loading tray assembly acts on the first operating part, causing the locking rod to be in an unlocked state. When the loading tray assembly is rotated relative to the tray assembly, the locking hook can rotate around the first hinge to hook the limiting block, thereby being in a locked state.

[0012] In some embodiments, the loading tray assembly is provided with a locking grid, and the movable loading device further includes a combination locking device fixed to the base assembly, the combination locking device being used to lock or unlock the locking grid.

[0013] Secondly, another technical solution adopted in this application is: providing a trunk system, including: a trunk; a movable loading device disposed in the trunk, wherein, in a third direction, there is a gap between the loading tray assembly in the movable loading device and the rear panel of the trunk, wherein the gap is greater than 5mm, the loading surface of the loading tray assembly is higher than the rear panel, and the distance between the loading surface of the loading tray assembly and the rear panel is greater than or equal to 20mm and less than or equal to 30mm; wherein, the movable loading device is the movable loading device described in the first aspect.

[0014] The beneficial effects of this application are as follows: Unlike existing technologies, the movable loading device provided in this application is applied to a trunk system and includes: a base assembly; a drive assembly fixed to the base assembly; a support frame assembly driven by the drive assembly, the support frame assembly being able to move relative to the base assembly under the drive of the drive assembly; and a loading tray assembly for loading items, the loading tray assembly being disposed on the support frame assembly and hinged to the support frame assembly, allowing the loading tray assembly to extend or retract along with the support frame assembly and also to flip relative to the support frame assembly. In the technical solution of this application, under the drive of the drive assembly, the loading tray assembly can move along with the support frame assembly to deliver or return items placed on it to the trunk, thereby facilitating user access to items; the loading tray assembly is hinged to the support frame assembly, allowing the loading tray assembly to also flip relative to the support frame assembly, so that when there are no items on the loading tray assembly, items can be accessed and placed in the storage compartment by flipping the loading tray assembly. In this way, the mobile loading device makes it convenient for users to pick up and put down the items placed on it, without affecting the user's ability to retrieve and put down the items in the storage compartments.

[0037] In this application, the first direction refers to the direction of the Y-axis, the second direction refers to the direction of the X-axis, and the third direction refers to the direction of the Z-axis. The X-axis, Y-axis, and Z-axis are all perpendicular to each other.

[0038] The movable loading device provided in this application is applied to a trunk system and includes: a base assembly; a drive assembly fixed to the base assembly; a support frame assembly driven by the drive assembly, the support frame assembly being movable relative to the base assembly under the drive of the drive assembly; and a loading tray assembly for loading items, the loading tray assembly being disposed on the support frame assembly and hinged to the support frame assembly, allowing the loading tray assembly to move with the support frame assembly and to flip relative to the support frame assembly. In the technical solution of this application, under the drive of the drive assembly, the loading tray assembly can move with the support frame assembly to deliver or return items placed on it to the trunk, thereby facilitating user access to items; the loading tray assembly is hinged to the support frame assembly, allowing the loading tray assembly to also flip relative to the support frame assembly, so that when there are no items on the loading tray assembly, items can be placed in the storage compartment by flipping the loading tray assembly. In this way, the movable loading device facilitates user access to items placed on it without affecting the user's access to items in the storage compartment.

[0039] Please see Figure 1 and Figure 2 .in, Figure 1 This is a schematic diagram of the structure of a vehicle with the movable loading device in an extended state, according to some embodiments of this application. Figure 2 This is a structural schematic diagram of a vehicle with the movable loading device in a flipped state, as provided in some embodiments of this application. The vehicle 1000 provided in this application is equipped with a trunk system 300. The trunk system 300 provided in this application includes, but is not limited to, a trunk 200 and a movable loading device 100. The movable loading device 100 is installed inside the trunk 200. In a third-party direction, there is a gap between the loading tray assembly 108 in the movable loading device 100 and the rear panel of the trunk 200. This gap is greater than 5mm to ensure that the loading tray assembly 108 can still move freely without interfering with the rear panel when carrying items. The loading surface of the loading tray assembly is higher than the rear panel, and the distance between the loading surface of the loading tray assembly 108 and the rear panel is greater than or equal to 20mm and less than or equal to 30mm, to ensure the loading space of the trunk 200, while also reserving necessary movement space for the flipping operation of the loading tray assembly 108. In this way, not only is the space utilization of the trunk 200 improved, but the smoothness and stability of the loading tray assembly 108 during movement are also ensured.

Figure 10 yes Figure 3 A partially enlarged schematic diagram of the mobile loading device at area A. Figure 11 yes Figure 3 A partially enlarged schematic diagram of the movable loading device at region B. The movable loading device 100 provided in this application is applied to a trunk system 300. The movable loading device 100 includes, but is not limited to, a base assembly 101, a support frame assembly 102, a drive assembly 103, a drive rod 104, at least one reel 105, at least one guide wheel 106, and at least one pull rope 107. The support frame assembly 102 is movably connected to the base assembly 101. The drive assembly 103 is fixed to the base assembly 101 to provide power to the movable loading device 100. The support frame assembly 102 is drivenly connected to the drive assembly 103. Specifically, the drive rod 104 is drivenly connected to the output end of the drive assembly 103 to transmit the power of the drive assembly 103 to the reel 105. The reel 105 is drivenly connected to the drive rod 104 to achieve the winding and unwinding of the pull rope 107 through the rotation of the reel 105. The guide wheel 106 is rotatably connected to the base assembly 101, and provides guidance for the pull rope 107 to ensure that the pull rope 107 moves along a preset path. One end of the pull rope 107 is connected to the support frame assembly 102 at a first connection position, and the other end of the pull rope 107 is connected to the support frame assembly 102 at a second connection position. The pull rope 107 can start from the first connection position, wind around the winding wheel 105 several times, and then be guided by the guide wheel 106 to reach the second connection position. In this embodiment, the support frame assembly 102 can extend or retract relative to the base assembly 101 under the drive of the drive assembly 103, thereby facilitating the user to pick up and put down items and increasing user comfort.

[0041] In this embodiment, there are two reels 105, two guide wheels 106, and two pull ropes 107. One end of the drive rod 104 is connected to one reel 105, and the other end of the drive rod 104 is connected to the other reel 105, so that the support frame assembly 102 is subjected to uniform force during the extension or retraction relative to the base assembly 101, avoiding tilting or jamming caused by uneven force on one side. One pull rope 107 can start from a first connection position, wind around a reel 105 several times, and then be guided by a guide wheel 106 to reach a second connection position. The other pull rope 107 can start from another first connection position, wind around another reel 105 several times, and then be guided by another guide wheel 106 to reach another second connection position. In this way, greater pulling force can be provided, so that the pull rope 107 can precisely control the movement of the tray assembly 102 under the drive of the reel 105, ensuring that when a lot of items are placed on the tray assembly 102, it can still be stably extended or retracted relative to the base assembly 101.

[0042] Furthermore, the support frame assembly 102 includes, but is not limited to, a first base plate 1021, at least one first connector 1022, and at least one second connector 1023. One end of the pull rope 107 is engaged with the first connector 1022, and the other end is engaged with the second connector 1023. Specifically, the first connector 1022 is fixed to the first base plate 1021. The second connector 1023 is fixed to the first base plate 1021. The first connector 1022 and the second connector 1023 are located on the same side of the first base plate 1021, ensuring that the two connection points of each pull rope 107 with the support frame assembly 102 are in the same plane. This guarantees that the pull rope 107 experiences uniform force during movement and prevents it from becoming skewed or jammed. The first connector 1022 is closer to the reel 105 than the second connector 1023. One end of the pull rope 107 is connected to the first connector 1022 at the first connection position, and the other end of the pull rope 107 is connected to the second connector 1023 at the second connection position.

[0043] Understandably, given the two pull ropes 107 in this embodiment, two first connectors 1022 and two second connectors 1023 can be correspondingly provided. Specifically, along the length of the first base plate 101, one first connector 1022 is located at one end of the first base plate 1021, and the other first connector 1022 is located at the other end of the first base plate 1021. Along the length of the first base plate 101, one second connector 1023 is located at one end of the first base plate 1021, and the other second connector 1023 is located at the other end of the first base plate 1021. One end of one pull rope 107 is engaged with a first connector 1022, and the other end is engaged with a second connector 1023. One end of another pull rope 107 is engaged with another first connector 1022, and the other end is engaged with another second connector 1023.

[0044] Furthermore, the support frame assembly 102 also includes at least two first helical springs 1024 and at least two spring seats 1025 with capped edges. A first connector 1022 is provided with a first open slot 1022a. A second connector 1023 is provided with a second open slot 1023a. The pull rope 107 includes a rope body 1071 and two capped cylindrical ends 1072. The pull rope 107 can apply traction to the support frame assembly 102, converting the rotational motion of the reel 105 into the telescopic motion of the support frame assembly 102. One cylindrical end 1072 is connected to one end of the rope body 1071, and the other cylindrical end 1072 is connected to the other end of the rope body 1071. One spring seat 1025 and one cylindrical end 1072 are disposed in the first open slot 1022a, and the other spring seat 1025 and the other cylindrical end 1072 are disposed in the second open slot 1023a. In this configuration, one end of a first helical spring 1024 is fitted onto a spring seat 1025, and the other end is fitted onto a cylindrical end 1072. The first helical spring 1024 is pre-compressed between the cap edge of the spring seat 1025 and the cap edge of the cylindrical end 1072. Another first helical spring 1024 is fitted onto another spring seat 1025, and the other end is fitted onto another cylindrical end 1072. This second first helical spring 1024 is pre-compressed between the cap edge of the other spring seat 1025 and the cap edge of the other cylindrical end 1072. Understandably, the restoring force of the first helical spring 1024 keeps the pull rope 107 taut, allowing it to respond instantly to the rotation of the winding wheel 105 and pull the support frame assembly 102, while ensuring the smooth movement of the support frame assembly 102.

[0045] In this embodiment, the first connector 1022 has a first engaging portion 1022b at one end facing the reel 105. The base assembly 101 has a second engaging portion 1011. The first engaging portion 1022b engages with the second engaging portion 1011, allowing the first connector 1022 to be detachably connected to the base assembly 101. Specifically, when the reel 105 rotates forward, under the traction of the pull rope 107, the first engaging portion 1022b and the second engaging portion 1011 can disengage from each other, and the support frame assembly 102 extends relative to the base assembly 101. When the reel 105 rotates in the reverse direction, under the traction of the pull rope 107, the first engaging portion 1022b and the second engaging portion 1011 engage with each other, and the support frame assembly 102 retracts relative to the base assembly 101. It should be noted that in this embodiment, forward rotation can refer to clockwise rotation or counterclockwise rotation, and reverse rotation is the rotation direction opposite to forward rotation. For example, when the forward rotation is clockwise, the reverse rotation is counterclockwise; when the forward rotation is counterclockwise, the reverse rotation is clockwise.

[0046] Furthermore, the support frame assembly 102 also includes an elastic limiting pad 1026. One end of the elastic limiting pad 1026 is provided with a third locking portion 1026a. The other end of the elastic limiting pad 1026 is provided with a fourth locking portion 1026b. The third locking portion 1026a engages with the first locking portion 1022b, so that the elastic limiting pad 1026 is fixedly connected to the first connecting member 1022, ensuring that the elastic limiting pad 1026 can move synchronously with the support frame assembly 102 and avoid falling off. The fourth locking portion 1026b engages with the second locking portion 1011, so that the elastic limiting pad 1026 is detachably connected to the base assembly 101. Specifically, when the winding reel 105 rotates in the forward direction, under the traction force of the pull rope 107, the second locking portion 1011 and the fourth locking portion 1026b can disengage from each other, and the support frame assembly 102 extends relative to the base assembly 101. When the reel 105 rotates in the reverse direction, under the traction of the pull rope 107, the second locking part 1011 and the fourth locking part 1026b engage with each other, and the support frame assembly 102 retracts relative to the base assembly 101. Understandably, by providing an elastic limiting pad 1026 between the first locking part 1022b and the second locking part 1011, direct collision between the support frame assembly 102 and the base assembly 101 can be prevented. This provides flexible buffering when the support frame assembly 102 approaches the base assembly 101, absorbing some vibration and impact energy, thereby reducing noise and wear between the support frame assembly 102 and the base assembly 101.

[0047] Furthermore, the base assembly 101 also includes a first frame assembly 1012, at least one slide rail 1013, and at least one slider 1014. The slide rail 1013 is fixed to the first frame assembly 1012 and extends along a second direction, providing a sliding path for the slider 1014. The slider 1014 is slidably connected to the slide rail 1013. The support frame assembly 102 is fixed to the slider 1014 to ensure the synchronization of movement between the support frame assembly 102 and the slider 1014, and to avoid relative displacement between the support frame assembly 102 and the slider 1014. In this way, the support frame assembly 102 can reciprocate linearly along the slide rail 1013 under the drive of the slider 1014, thereby realizing the extension and retraction of the support frame assembly 102 relative to the base assembly 101.

[0048] In this embodiment, two slide rails 1013 and two sliders 1014 are provided. The two slide rails 1013 are spaced apart along a first direction, thereby providing double-sided support for the support frame assembly 102 and enhancing stability. One slider 1014 is slidably connected to one slide rail 1013, and the other slider 1014 is slidably connected to the other slide rail 1013, ensuring the independence and stability of the movement of the two sliders 1014. This allows the other slider 1014 to continue guiding the support frame assembly 102 even if one slider 1014 fails. In the first direction, one end of the support frame assembly 102 is fixed to one slider 1014, and the other end is fixed to the other slider 1014. This further strengthens the connection stability between the support frame assembly 102 and the sliders 1014, improves the smoothness of the movement of the support frame assembly 102 relative to the base assembly 101, and also distributes the load to extend the service life of the slide rails 1013 and sliders 1014.

[0049] Further, the first frame assembly 1012 includes, but is not limited to, a first profile 1012a, a second profile 1012b, a second base plate 1012c, and a third base plate 1012d. In a second direction, the second base plate 1012c and the third base plate 1012d are spaced apart, providing a stable mounting reference for the first profile 1012a and the second profile 1012b. Both the second base plate 1012c and the third base plate 1012d extend along a first direction. The first profile 1012a and the second profile 1012b are spaced apart in the first direction. The first profile 1012a and the second profile 1012b extend along a second direction. The first profile 1012a is fixed between the second base plate 1012c and the third base plate 1012d. The second profile 1012b is fixed between the second base plate 1012c and the third base plate 1012d. One slide rail 1013 is fixed to the first profile 1012a, and another slide rail 1013 is fixed to the second profile 1012b. The base assembly 101 also includes several support wheel assemblies 1015. The several support wheel assemblies 1015 are fixed to the third base plate 1012d, providing movable support for the loading tray assembly 108, facilitating the adjustment of the position of the tray frame assembly 102 in the trunk. In this embodiment, the rollers of the support wheel assembly 1015 abut against the loading tray assembly 108, providing guidance and support for the extension and retraction of the loading tray assembly 108 relative to the base assembly 101.

[0050] Further, the drive assembly 103 includes a geared motor 1031, an output gear 1032, a first double gear 1033, and a drive gear 1034. Specifically, the geared motor 1031 has a planetary gear reducer. The output end of the geared motor 1031 is connected to the output gear 1032. The output gear 1032 meshes with the large teeth of the first double gear 1033, and the small teeth of the first double gear 1033 mesh with the drive gear 1034, thereby amplifying the torque output by the geared motor 1031, reducing the speed of the drive gear 1034, and thus improving the motion stability of the loading tray assembly 108. The drive gear 1034 is connected to the drive rod 104. In this embodiment, the drive gear 1034 transmits the torque output by the geared motor 1031 to the drive rod 104, and the drive rod 104 synchronously drives the winding reel 105 to rotate, so as to realize the extension or retraction of the support frame assembly 102 relative to the base assembly 101.

[0051] In this embodiment, the pull rope 107 is preferably a steel wire rope to ensure that it has sufficient toughness to withstand the large tensile force during the extension and retraction of the support frame assembly 102, avoiding the risk of breakage and enabling the pull rope 107 to stably pull the support frame assembly 102 relative to the base assembly 101. At the same time, the steel wire rope has a certain rigidity, making it less prone to deformation or knotting during winding and releasing relative to the reel 105, thus ensuring the smoothness and reliability of the extension and retraction movement of the support frame assembly 102 relative to the base assembly 101.

[0052] Furthermore, the movable loading device 100 provided in this application also includes a loading tray assembly 108. The loading tray assembly 108 is used for loading items. The loading tray assembly 108 is disposed on the tray assembly 102, allowing the loading tray assembly 108 to move with the tray assembly 102, facilitating the user's placement and removal of items. The loading tray assembly 108 is hinged to the tray assembly 102, allowing the loading tray assembly 108 to rotate relative to the base assembly 101.

[0053] Specifically, in this embodiment, two first connectors 1022 are provided. Each first connector 1022 has a hinge hole 1027. The hinge hole 1027 of one first connector 1022 and the hinge hole 1027 of the other first connector 1022 are located on the same central axis. The loading tray assembly 108 is hinged to the support frame assembly 102 through the hinge hole 1027, allowing the loading tray assembly 108 to rotate relative to the support frame assembly 102.

[0054] In this embodiment, the loading tray assembly 108 includes, but is not limited to, the second frame assembly 1081 and the tray 1082. The tray 1082 is used to support items. The tray 1082 is fixed to the second frame assembly 1081.

[0055] Furthermore, the second frame assembly 1081 includes a third profile 1081a and a fourth profile 1081b. In a first direction, the third profile 1081a and the fourth profile 1081b are spaced apart. Both the third profile 1081a and the fourth profile 1081b extend along a second direction. A support plate 1082 is fixed between the third profile 1081a and the fourth profile 1081b. In this way, the support plate 1082 can be provided with double-sided support, enhancing its load-bearing capacity.

[0056] Furthermore, the loading tray assembly 108 also includes a plurality of anti-slip decorative strips 1083. The plurality of anti-slip decorative strips 1083 are disposed on the loading surface of the pallet 1082 to increase the coefficient of friction of the loading surface of the pallet 1082, prevent items from slipping when the vehicle 1000 is moving or when the loading tray assembly 108 moves relative to the chassis assembly, and also improve the overall aesthetics of the loading tray assembly 108.

[0057] In some other embodiments, please refer to Figure 9The loading tray assembly 108 also includes a limiting rod 1084, a first mounting base 1085, and a second mounting base 1086. The first mounting base 1085 is fixed to a third profile 1081a. The second mounting base 1086 is fixed to a fourth profile 1081b. The limiting rod 1084 spans the pallet 1082 along a first direction and is fixed to the first mounting base 1085 and the second mounting base 1086, so that the limiting rod 1084 can form a support structure along the first direction on the loading surface of the pallet 1082, effectively preventing excessive sliding or displacement of items due to bumps or sudden stops during vehicle 1000 operation. In this way, the limiting rod 1084 can work together with the anti-slip decorative strip 1083 to prevent items placed on the cargo surface from falling off or from excessively shifting relative to the pallet 1082 when the vehicle 1000 is moving or the loading tray assembly 108 moves relative to the base plate assembly, thereby improving cargo safety. At the same time, the limiting rod 1084 also protects the anti-slip decorative strip 1083 set on the surface of the pallet 1082, preventing wear or damage to the anti-slip decorative strip 1083 due to excessive slippage of items.

[0058] Furthermore, the second frame assembly 1081 also includes a first guide rail 1081c and a second guide rail 1081d. The first guide rail 1081c is built into the third profile 1081a. The second guide rail 1081d is built into the fourth profile 1081b. A first mounting base 1085 is slidably connected to the first guide rail 1081c. A second mounting base 1086 is slidably connected to the second guide rail 1081d. Through the sliding of the first mounting base 1085 on one guide rail, the second mounting base 1086 simultaneously slides on the second guide rail 1081d. In this way, the user can flexibly adjust the position of the limiting rod 1084 according to the shape and size of the items loaded on the loading tray to achieve the best limiting effect and improve the space utilization of the movable loading device 100.

[0059] Furthermore, both the first guide rail 1081c and the second guide rail 1081d are provided with several locking positions. These locking positions are evenly distributed along the second direction on the first guide rail 1081c and the second guide rail 1081d. The first mounting base 1085 is engaged with the first guide rail 1081c via the locking positions. The second mounting base 1086 is engaged with the second guide rail 1081d via the locking positions. The user can quickly engage the first mounting base 1085 and the second mounting base 1086 with the desired locking positions, or release them from the locking positions, to precisely adjust the position of the limiting rod 1084. In this way, multiple position options are provided to the user to adapt to the limiting requirements of items of different sizes.

[0060] Furthermore, the second frame assembly 1081 also includes a fifth profile 1081e, a sixth profile 1081f, a first corner connector 1081g, a second corner connector 1081h, a third corner connector 1081j, and a fourth corner connector 1081k. In the second direction, the fifth profile 1081e and the sixth profile 1081f are spaced apart. Both the fifth profile 1081e and the sixth profile 1081f extend along the first direction. The fifth profile 1081e is connected to the third profile 1081a via the first corner connector 1081g. The fifth profile 1081e is also connected to the fourth profile 1081b via the second corner connector 1081h. The sixth profile 1081f is connected to the third profile 1081a via the third corner connector 1081j. The sixth profile 1081f is also connected to the fourth profile 1081b via the fourth corner connector 1081k. In this way, the overall structural strength and stability of the frame are enhanced, thereby improving the load-bearing capacity of the loading disk assembly 108.

[0061] In this embodiment, both the first corner connector 1081g and the second corner connector 1081h are provided with hinge holes 1027. Specifically, the first corner connector 1081g is hinged to the first connector 1022 through the hinge hole 1027. The second corner connector 1081h is hinged to the second connector 1023 through the hinge hole 1027. It can be understood that the hinge holes 1027 provided on the first corner connector 1081g and the second corner connector 1081h correspond to the hinge holes 1027 provided on the first connector 1022 and the second connector 1023. At least one hinge shaft is inserted into the hinge hole 1027 to ensure that the loading tray assembly 108 rotates around the same axis.

[0062] Furthermore, the loading tray assembly 108 also includes a handle assembly 1089b. Specifically, the handle assembly 1089b is fixed to the tray 1082. In this embodiment, the handle assembly 1089b is installed at one end of the tray 1082 near the sixth profile 1081f to facilitate manual operation. In the event of a power outage or damage to the drive assembly 103, or other situations where the loading tray assembly 108 cannot be driven electrically, the user can manually pull the loading tray assembly 108 using the handle assembly 1089b to extend and retract the loading tray assembly 108 relative to the base assembly 101 and flip it relative to the tray frame assembly 102.

[0063] Furthermore, the movable loading device 100 also includes a support rod 109. One end of the support rod 109 is connected to the support frame assembly 102, and the other end of the support rod 109 is connected to the loading tray assembly 108. Driven by the support rod 109, the loading tray assembly 108 can rotate relative to the support frame assembly 102. In this embodiment, the support rod 109 is preferably an electric support rod. Specifically, under electric drive, the support rod 109 performs a telescopic movement, and the end of the support rod 109 connected to the loading tray assembly 108 pushes the loading tray assembly 108 to rotate around the hinge hole 1027. By providing an electric support rod, the user does not need to manually operate the loading tray assembly 108, thus improving the convenience of user operation.

[0064] Furthermore, the movable loading device 100 also includes a first mounting bracket 110 and a second mounting bracket 111. The first mounting bracket 110 is fixed to the support frame assembly 102. The second mounting bracket 111 is fixed to the loading tray assembly 108. One end of the support rod 109 is ball-jointed to the first mounting bracket 110. The other end of the support rod 109 is ball-jointed to the second mounting bracket 111. In this way, the support rod 109 can rotate in multiple directions, allowing the support rod 109 to freely adjust its angle during the flipping process, avoiding jamming or interference, thereby ensuring that the loading tray assembly 108 can perform a smooth flipping action.

[0065] Furthermore, the movable loading device 100 also includes a balance bar 112. One end of the balance bar 112 is connected to the support frame assembly 102, and the other end is connected to the loading tray assembly 108, working together with the support rod 109 to support the loading tray assembly 108 and improve the overall stability of the tilting mechanism. In the first direction, the balance bar 112 and the support rod 109 are spaced apart. The balance bar 112 can assist the support rod 109 in opening or closing the loading tray assembly 108, and under the action of the balance bar 112, the loading tray assembly 108 can be suspended at any position during the tilting process. In this embodiment, the balance bar 112 is preferably a gas spring, which can absorb some vibration and impact during the tilting process of the loading tray assembly 108. Of course, in some other embodiments, a mechanical spring can also be provided inside the balance bar 112.

[0066] Furthermore, the movable loading device 100 also includes a third mounting bracket 113 and a fourth mounting bracket 114. The third mounting bracket 113 is fixed to the support frame assembly 102, and the fourth mounting bracket 114 is fixed to the loading tray assembly 108. The third mounting bracket 113 and the fourth mounting bracket 114 provide a stable mounting position for the balance bar 112. One end of the balance bar 112 is ball-jointed to the third mounting bracket 113. The other end of the balance bar 112 is ball-jointed to the fourth mounting bracket 114. In this way, the balance bar 112 can rotate in multiple directions, allowing it to freely adjust its angle during the flipping process, avoiding jamming or interference with other components, thereby ensuring smooth flipping action and improving the user's operating experience.

[0067] The movable loading device 100 also includes a limiting block 115 and a locking rod 116. The limiting block 115 is fixed to the base assembly 101. The locking rod 116 includes a locking hook portion 1161, a first hinge portion 1162, and a first operating portion 1163. The first hinge portion 1162 connects the locking hook portion 1161 and the first operating portion 1163. The first hinge portion 1162 is hinged to the support frame assembly 102. When the loading tray assembly 108 is not flipped relative to the support frame assembly 102, the loading tray assembly 108 acts on the first operating portion 1163, causing the locking rod 116 to be in an unlocked state. This allows the loading tray assembly 108 to extend or retract directly relative to the base assembly 101 with the support frame assembly 102 in non-flipped scenarios, meeting the user's needs in different scenarios. When the loading tray assembly 108 is flipped relative to the support frame assembly 102, the locking hook portion 1161 can rotate around the first hinge portion 1162 and hook onto the limiting block 115, thereby entering a locked state. In the locked state, the locking rod 116, through the cooperation of the locking hook portion 1161 and the limiting block 115, fixes the support frame assembly 102 onto the base assembly 101, preventing the support frame assembly 102 from moving along the slide rail 1013 during the flipping of the loading tray assembly 108. In this way, the movable loading device 100 of this embodiment not only achieves the stability and safety of the loading tray assembly 108 in different states, but also significantly improves the user's operational convenience.

[0068] Furthermore, the movable loading device 100 also includes a cover curtain assembly 117. The cover curtain assembly 117 is fixed to the base assembly 101. The drive assembly 103 is located between the cover curtain assembly 117 and the frame assembly 102. The cover curtain assembly 117 includes a roller blind 1171. The fixing strip of the roller blind 1171 is fixed to the side of the frame assembly 102 near the winding reel 105. The roller blind 1171 can extend and retract with the extension and retraction of the frame assembly 102, so that the roller blind 1171 automatically unfolds when the frame assembly 102 extends to cover the items loaded at the bottom of the frame assembly 102 and protect the user's privacy.

[0069] In this embodiment, the process of the loading tray assembly 108 extending relative to the base assembly 101 is as follows: the locking rod 116 and the limiting block 115 are in the unlocked state, the driving assembly 103 drives the winding wheel 105 to rotate through the driving rod 104, the end of the pull rope 107 connected to the second connecting member 1023 is gradually wound up to the winding wheel 105 through the guide wheel 106, the end of the pull rope 107 connected to the first connecting member 1022 is gradually released, under the traction of the pull rope 107, the support frame assembly 102 moves along the slide rail 1013, and the loading tray assembly 108 gradually extends out of the base assembly 101 under the drive of the support frame assembly 102, while the roller curtain 1171 also unfolds as the support frame assembly 102 extends. The process of the loading tray assembly 108 retracting relative to the base assembly 101 is the reverse of the extension process.

[0070] The process of the loading tray assembly 108 flipping relative to the support frame assembly 102 is as follows: The support rod 109 is activated, and under the thrust applied by the support rod 109, the loading tray assembly 108 is pushed to rotate around the hinge hole 1027. The balance bar 112 (a gas spring in this embodiment) operates simultaneously with the support rod 109, providing auxiliary thrust to help the loading tray assembly 108 flip more smoothly. When the loading tray assembly 108 detaches from the base assembly 101 and begins to flip, the locking hook 1161 rotates around the first hinge 1162 under the action of gravity, hooking the limiting block 115, causing the locking rod 116 to enter the locked state, fixing the support frame assembly 102 to the base assembly 101. The loading tray assembly 108 can then complete the flipping under the action of the support rod 109, and can be suspended at any position during the flipping process under the action of the balance bar 112.

[0071] Please refer to the following: Figures 12-16 . Figure 12 This is an exploded view of a combination lock device provided in some embodiments of this application. Figure 13 This is a schematic diagram of the structure of the rotary latch provided in some embodiments of this application. Figure 14 This is a schematic diagram of the locking mechanism provided in some embodiments of this application. Figure 15 This is a schematic diagram of the structure of the telescopic seat provided in some embodiments of this application. Figure 16 This is a schematic diagram of the translational locking tongue provided in some embodiments of this application. The movable loading device 100 provided in this embodiment also includes a combination locking device 118. The combination locking device 118 is fixed to the base assembly 101. Accordingly, please refer to Figure 8 In this embodiment, the loading tray assembly 108 further includes a locking gate 1089a. The locking gate 1089a is fixed to the side of the pallet 1082 facing away from the loading surface, providing a locking interface for the combination locking device 118 and cooperating with it. Specifically, the combination locking device 118 is used to lock or unlock the locking gate 1089a to achieve locking and unlocking of the loading tray assembly 108.

[0072] The combination lock device 118 is an integrated manual and automatic combination lock device. That is, the combination lock device 118 provided in this embodiment can achieve automatic locking and unlocking via electric means or manual means. In this embodiment, the automatic locking or unlocking function can be automatically triggered when the vehicle 1000 starts or the loading tray assembly 108 is in place, reducing the user's operational burden. Manual locking or unlocking can provide an emergency locking and unlocking method in case the automatic lock fails.

[0073] Specifically, the combination lock device 118 provided in this embodiment includes, but is not limited to, a fifth mounting bracket 1181, a rotating bolt 1182, a locking catch 1183, a driver 1184, and a sliding bolt 1185. The rotating bolt 1182 is hinged to the fifth mounting bracket 1181, allowing the rotating bolt 1182 to rotate relative to the fifth mounting bracket 1181 for locking and unlocking the lock gate 1089a. The fifth mounting bracket 1181 is fixedly connected to the third base plate 1012d of the base assembly 101. The locking catch 1183 is hinged to the fifth mounting bracket 1181, allowing the locking catch 1183 to rotate relative to the fifth mounting bracket 1181 for easy engagement with the rotating bolt 1182. Specifically, the locking catch 1183 can lock the rotating bolt 1182 when it has rotated to its designated position, preventing accidental rotation of the rotating bolt 1182 and ensuring a stable locking state. The actuator 1184 is fixed to the fifth mounting bracket 1181 to provide electric driving force, enabling the automatic unlocking and locking functions of the combination lock device 118. The sliding bolt 1185 is drive-connected to the actuator 1184. The actuator 1184 provides driving force, driving the sliding bolt 1185 to reciprocate linearly in a direction perpendicular to the loading tray assembly 108. Driven by the actuator 1184, the sliding bolt 1185 can act on the locking latch 1183 to release the rotating bolt 1182, thereby allowing the locking gate 1089a to disengage from the rotating bolt 1182, thus achieving unlocking. This method avoids accidental unlocking and improves the stability of the movable loading device 100 in the locked state.

[0074] The rotating latch 1182 includes at least a first engaging portion 1182a, a locking groove 1182b, and a second hinge portion 1182c. The rotating latch 1182 is hinged to the fifth mounting bracket 1181 via the second hinge portion 1182c, forming a rotation fulcrum. The first engaging portion 1182a and the locking groove 1182b are formed on the periphery of the second hinge portion 1182c. The locking groove 1182b is used to engage with the lock gate 1089a. Specifically, in the locked state, the lock gate 1089a is placed within the locking groove 1182b. The locking catch 1183 includes at least a second engaging portion 1183a, a second operating portion 1183b, and a third hinge portion 1183c. The third hinge portion 1183c connects the second engaging portion 1183a and the second operating portion 1183b. The locking buckle 1183 is hinged to the fifth mounting bracket 1181 via the third hinge portion 1183c. The first engaging portion 1182a is used to cooperate with the second engaging portion 1183a of the locking buckle 1183 to realize the locking function.

[0075] When the locking gate 1089a acts on the locking groove 1182b, specifically, after the locking gate 1089a enters the locking groove 1182b, the locking gate 1089a can push the rotating bolt 1182 to rotate until the first engaging part 1182a and the second engaging part 1183a are engaged, completing the locking action. At this time, the rotating bolt 1182 is locked by the locking catch 1183 and cannot rotate back. In this way, the movement of the loading tray assembly 108 can be restricted, preventing it from accidentally flipping or extending during the driving of the vehicle 1000, thus improving system safety.

[0076] In the locked state, the second engaging part 1183a engages with the first engaging part 1182a of the rotating latch 1182, preventing the rotating latch 1182 from rotating. When unlocking is required, the translational latch 1185, driven by the actuator 1184, pushes the second operating part 1183b, causing the locking latch 1183 to rotate around the third hinge part 1183c until the second engaging part 1183a releases the first engaging part 1182a. At this time, the loading tray assembly 108 can rotate or extend relative to the base assembly 101 until the locking gate 1089a disengages from the locking groove 1182b, thereby unlocking. In this way, accidental unlocking is avoided, and the stability of the movable loading device 100 in the locked state is improved.

[0077] Furthermore, the combination lock device 118 also includes a first torsion spring 1186 and a second torsion spring 1187 to further enhance the automatic reset capability and operational reliability of the combination lock device 118. Specifically, the second hinge portion 1182c is hinged to the fifth mounting bracket 1181 via a first rotating shaft 1188a, the first torsion spring 1186 is sleeved on the rotating shaft, and one torsion arm of the first torsion spring 1186 acts on the rotating bolt 1182. In this way, after the rotating bolt 1182 completes the unlocking action, it can automatically reset to the initial position under the elastic force of the first torsion spring 1186, without relying on external driving force or manual operation, thereby improving the automation level of the combination lock device 118. At the same time, the second torsion spring 1187 is sleeved on the third hinge portion 1183c of the locking latch 1183, and one torsion arm of the second torsion spring 1187 acts on the second operating portion 1183b of the locking latch 1183. In this way, it can be ensured that after the translational locking tongue 1185 is released, the locking latch 1183 can be dynamically reset to its initial position under the elastic force of the second torsion spring 1187. This ensures that the locking latch 1183 can lock the rotating locking tongue 1182 during the next locking process, avoiding locking failure caused by the locking latch 1183 not resetting in time. At the same time, under the bumpy or vibrating environment of the vehicle 1000, the first torsion spring 1186 and the second torsion spring 1187 can ensure that the rotating locking tongue 1182 and the locking latch 1183 always remain in the set position, preventing unlocking action caused by inertial force or external impact.

[0078] Furthermore, the driver 1184 includes, but is not limited to, a housing 1184a, a motor 1184b, a transmission assembly 1184c, and a telescopic base 1184d. The driver 1184 is fixed to the fifth mounting bracket 1181. Specifically, the housing 1184a is fixed to the fifth mounting bracket 1181. The motor 1184b is fixedly mounted inside the housing 1184a. The input end of the transmission assembly 1184c is connected to the output end of the motor 1184b to convert the high-speed, low-torque power output by the motor 1184b into low-speed, high-torque power suitable for driving the locking latch 1183 and rotating the locking tongue 1182, thereby ensuring the stability of the driving process. The telescopic base 1184d is connected to the output end of the transmission assembly 1184c, allowing the telescopic base 1184d to perform linear reciprocating motion under the drive of the transmission assembly 1184c. In this embodiment, the sliding latch 1185 is slidably connected to the telescopic seat 1184d, and the sliding latch 1185 can move in the same direction as the telescopic seat 1184d. It can be understood that in this embodiment, the transmission assembly 1184c is driven by the motor 1184b, and the transmission assembly 1184c then drives the telescopic seat 1184d and the sliding latch 1185 to move in the same direction. Users can control the forward and reverse rotation of the output shaft of the motor 1184b to automatically lock or unlock the loading tray assembly 108, improving ease of use.

[0079] Furthermore, the transmission assembly 1184c includes, but is not limited to, a worm gear 1184e, a second double gear 1184f, and a screw gear 1184g. The worm gear 1184e is connected to the output shaft of the motor 1184b. The large tooth of the second double gear 1184f meshes with the worm gear 1184e, and the gear portion of the screw gear 1184g meshes with the small tooth of the second double gear 1184f. The screw portion of the screw gear 1184g meshes with the telescopic seat 1184d to convert the rotational motion of the screw gear 1184g into the linear motion of the telescopic seat 1184d. Specifically, the high-speed, low-torque driving force output by the motor 1184b is transmitted to the screw gear 1184g after the speed is reduced and the torque is increased by the double gear, so as to drive the screw gear 1184g to rotate, thereby driving the telescopic seat 1184d to make linear motion along the axial direction of the screw part of the screw gear 1184g, so that the telescopic seat 1184d drives the translational locking tongue 1185, and then drives the locking buckle 1183.

[0080] Furthermore, the telescopic seat 1184d includes at least a connected sliding part 1184h and a threaded part 1184j. The threaded part 1184j meshes with the screw portion of the screw gear 1184g to convert the rotational motion of the screw gear 1184g into the linear reciprocating motion of the telescopic seat 1184d. Simultaneously, the thread itself has a self-locking characteristic, ensuring that when the motor 1184b stops working, the telescopic seat 1184d can stably remain in its current position without displacement due to external forces, thus guaranteeing the stability of the unlocked or locked state. The sliding part 1184h has a strip-shaped through hole 1184k extending along the movement direction of the telescopic seat 1184d. The sliding latch 1185 passes through the strip-shaped through hole 1184k, forming a sliding fit with the telescopic seat 1184d, allowing the sliding latch 1185 to move along the length of the strip-shaped through hole 1184k.

[0081] Furthermore, the sliding joint 1184h is also provided with a circular through hole 1184m. The sliding latch 1185 is cross-shaped in overall shape. The sliding latch 1185 passes through both the strip-shaped through hole 1184k and the circular through hole 1184m.

[0082] Furthermore, the actuator 1184 also includes a second helical spring 1184n. The second helical spring 1184n is pre-compressed between the fifth mounting bracket 1181 and the translational locking tongue 1185. In some embodiments, the fifth mounting bracket 1181 is provided with a guide post, and the second helical spring 1184n is sleeved on the guide post, thereby providing stable support and guidance for the second helical spring 1184n, ensuring that the second helical spring 1184n moves in a straight line during compression and extension, and avoiding the spring from deflecting or twisting when under force. In this embodiment, by providing the second helical spring 1184n, it can play a role in buffering and resetting during the movement of the translational locking tongue 1185.

[0083] In this embodiment, the loading tray assembly 108 further includes a positioning strip 1087 and a positioning hole 1088. The positioning strip 1087 is fixed to the side of the pallet 1082 facing away from the surface of the load. The positioning hole 1088 is disposed on the side of the pallet 1082 facing away from the surface of the load. In the second direction, the positioning strip 1087 and the positioning hole 1088 are distributed along the same straight line. When the combination lock device 118 is unlocked, the loading tray assembly 108 extends relative to the base assembly 101 under the drive of the drive assembly 103. When the loading tray assembly 108 extends to near the preset position, the motor 1184b is reset in advance. When the loading tray assembly 108 extends to the preset position, the translational locking tongue 1185 enters the hole of the positioning strip 1087. At this time, the drive assembly 103 stops operating, locking the loading tray assembly 108 in the preset extended position. In other embodiments, the positioning strip 1087 may have multiple holes, and the translational locking tongue 1185 can engage with each of these holes to lock the loading tray assembly 108 in multiple different extended positions, improving the user experience. Specifically, when the loading tray assembly 108 retracts or flips to its initial position, the locking gate 1089a acts on the locking groove 1182b, causing the rotating locking tongue 1182 to rotate until the first engaging part 1182a engages with the second engaging part 1183a, thereby locking the rotating locking tongue 1182 with the locking catch 1183. Simultaneously, the driver 1184 drives the translational locking tongue 1185 to insert into the positioning hole 1088, completing the double locking at the initial position. In this case, the positioning hole 1088 also serves as a clearance mechanism. When the loading tray assembly 108 needs to extend or flip from its initial position, the translational locking tongue 1185 first moves to disengage from the positioning hole 1088, and then moves to abut against the second operating part 1183b, causing the locking latch 1183 to rotate away from the first engaging part 1182a, thereby allowing the locking gate 1089a to disengage from the locking groove 1182b. When the loading tray assembly 108 extends relative to the base assembly 101, the loading tray assembly 108 can only be locked by the positioning strip 1087 on the loading tray assembly 108.

[0084] Furthermore, the combination lock device 118 also includes a second rotating shaft 1188b, a manual unlocking lever 1189a, a manual unlocking transmission shaft 1189b, and a manual unlocking handle assembly 1189c. The third hinge portion 1183c is hinged to the fifth mounting bracket 1181 via the second rotating shaft 1188b. The manual unlocking lever 1189a can abut against the second operating portion 1183b. The manual unlocking transmission shaft 1189b is drive-connected to the manual unlocking lever 1189a. Simultaneously, the manual unlocking transmission shaft 1189b is rotatably connected to the second rotating shaft 1188b. The manual unlocking handle assembly 1189c is drive-connected to the manual unlocking transmission shaft 1189b. In this manner, in the event of a failure of the actuator 1184 or other emergency, the user can manually unlock the movable loading device 100.

[0085] The manual unlocking process is as follows: the user operates the manual unlocking lever assembly 1189c, causing the manual unlocking lever 1189a to swing and apply force to the second operating part, so that the locking buckle 1183 rotates away from the first fastening part 1182a, thereby allowing the locking gate 1089a to disengage from the locking groove 1182b, thus achieving manual unlocking.

[0086] The manual unlocking process can also be as follows: the user operates the manual unlocking handle assembly 1189c, causing the manual unlocking lever 1189a to swing and apply force to the translational locking tongue 1185, causing the translational locking tongue 1185 to disengage from the hole on the positioning strip 1087.

[0087] The manual unlocking process can also be as follows: the user operates the manual unlocking lever assembly 1189c, causing the manual unlocking lever 1189a to swing and apply force to the translational locking tongue 1185, which further compresses the second helical spring 1184n until the translational locking tongue 1185 disengages from the hole on the positioning strip 1087 and acts on the second operating part 1163, causing the locking buckle 1183 to rotate away from the first fastening part 1182a, thereby allowing the locking gate 1089a to disengage from the locking groove 1182b to achieve manual unlocking.

[0088] The movable loading device 100 provided in this application is applied to a trunk system 300 and includes: a base assembly 101; a drive assembly 103 fixed to the base assembly 101; a tray assembly 102 drivenly connected to the drive assembly 103, the tray assembly 102 being able to move relative to the base assembly 103 under the drive of the drive assembly 103; and a loading tray assembly 108 for loading items, the loading tray assembly 108 being disposed on the tray assembly 102 and hinged to the tray assembly 102, so that the loading tray assembly 108 can move with the tray assembly 102 and can be flipped relative to the tray assembly 102. In the technical solution of this application, driven by the drive component 103, the loading tray assembly 108 can move along with the tray frame assembly 102 to deliver or return items placed on it to the trunk, thereby facilitating the user's retrieval of items. The loading tray assembly 108 is hinged to the tray frame assembly 102, allowing the loading tray assembly 108 to also rotate relative to the tray frame assembly 102. This enables the user to retrieve or place items in the storage compartment when there are no items on the loading tray assembly 108. In this way, the movable loading device 100 facilitates the user's retrieval of items placed on it without affecting the user's ability to retrieve or place items in the storage compartment.
