Description

Technical Field

[0001] The present disclosure relates to a vehicle trunk and a vehicle, belonging to the technical field of vehicles and vehicle accessories. Background Art

[0002] In the field of vehicle technology, the design of storage space has always been a key factor affecting the user experience. With the rapid popularization of electric vehicles, there are significant differences in their powertrain architectures compared to traditional fuel vehicles. Thanks to the elimination of the internal combustion engine and its associated components in electric vehicles, a large amount of idle space has been released in the vehicle's front compartment, enabling the realization of a new storage structure, the front trunk. The emergence of the front trunk not only expands the storage area for users but also meets their diverse storage needs for personal items, charging devices, emergency tools, etc. At the same time, the traditional rear trunk, as the core storage space that has continued to this day, still plays an important role in scenarios such as loading large luggage and household items. The two together constitute an important part of the modern vehicle storage system.

[0003] However, in the actual use process, there are many technical problems in the existing vehicle storage space. When the total amount of items loaded in the vehicle's front trunk and rear trunk exceeds the normal carrying capacity of the human hands, users face significant operational difficulties in the process of taking and placing items. When the storage box is loaded with items reaching or exceeding the normal carrying capacity of the human hands, it is difficult for users to complete the operation of taking and placing items at one time. For example, after a user stores various items such as work documents, shopping bags, and fitness equipment in the vehicle storage box, they cannot carry all the items at one time when leaving the vehicle and can only make multiple round trips to carry them, which greatly reduces the efficiency of taking and placing items.

[0004] In addition, in the scenario of placing items, after users purchase a large number of items such as food, beverages, and daily necessities, due to the limited carrying capacity of their hands, it is difficult to place all the items in the vehicle storage box at one time. At the same time, when users carry items with both hands, their actions will be restricted. For example, they cannot easily operate the parking lot exit gate, elevator buttons, and complete actions such as opening the door and taking the key, which affects the normal travel of users, poses potential safety hazards, and reduces the user experience. Summary of the Invention

[0005] In order to solve the above technical problems of the traditional vehicle trunk including the front and rear trunks, the present disclosure proposes a detachable and portable vehicle trunk, which greatly facilitates the operation of users to take, place, and carry items into and out of the trunk, achieving time-saving, labor-saving, and efficiency improvement.

[0006] Specifically, the first aspect of the present disclosure provides a vehicle luggage box, comprising: an outer box body, the outer box body being arranged on the vehicle body as the main body of the vehicle luggage box, and an inner box body, the inner box body being embedded in the inner side of the outer box body in a removable manner, so as to have a first state of being embedded in the inner side of the outer box body and a second state of being removed from the outer box body. One side of the inner box body has a retracted portion retracted toward the inside and a roller unit arranged in the retracted portion, so that in the first state, the roller of the roller unit is accommodated in the inside of the retracted portion and is sandwiched between the inner box body and the outer box body, and in the second state, the roller of the roller unit extends out from the retracted portion and is stuck in the extended state. One of the lower surface of the inner box body and the bottom surface of the outer box body is provided with a positioning protrusion, and the other is provided with a positioning recess matched with the positioning protrusion.

[0007] According to the vehicle luggage box with the above structure, the outer box body and the removable inner box body cooperate with the indentation part and the roller unit on the side of the inner box body to achieve the dual technical effects of space utilization and convenient transportation. In the first state, the roller unit is stored in the indentation part and sandwiched between the inner and outer boxes, without occupying additional storage space, ensuring that the inner box body and the outer box body are tightly fitted, maintaining the compactness of the overall structure of the luggage box, and effectively utilizing the vehicle space; in the second state, the roller of the roller unit extends from the indentation part and is locked, and the user can easily pull the inner box body to convert the heavy loaded items into rolling friction, greatly reducing the transportation resistance, solving the problem of limited carrying capacity and inconvenience of the user's hands when carrying heavy objects, and significantly improving the efficiency and convenience of taking and placing items. At the same time, the design of the indentation part to store and extend the roller avoids interference and wear of the roller when not in use, and avoids accidental retraction of the roller when in use, thereby improving the service life of the roller unit and the overall reliability of the luggage box. In addition, through the cooperation of the positioning protrusions and the positioning recesses between the inner box and the outer box, the position of the inner box relative to the outer box can be reliably positioned, and even if the vehicle vibrates during movement, there will be no misalignment or shaking between the two.

[0008] Preferably, in the vehicle trunk described in the first aspect, the roller unit includes: the roller, a roller mounting plate on which the roller is mounted, a spring sandwiched and mounted between the roller mounting plate and the bottom surface of the retracted portion, a storage hole arranged in the side surface of the retracted portion, and a limit block cooperating with the storage hole; wherein the limit block can switch between a storage position stored in the storage hole and a protruding position protruding from the storage hole, so that in the first state, the limit block is in the storage position, and in the second state, the limit block is in the protruding position to limit the movement of the roller mounting plate toward the retracted portion.

[0009] According to the vehicle luggage box having the above structure, the flexible switching and stable locking of the roller state can be achieved simply through the coordinated work of the roller, the roller mounting plate, the spring, the storage hole and the limit block. The spring clip is placed between the roller mounting plate and the bottom surface of the indentation to provide elastic support for the roller. In the first state, the limit block is stored in the storage hole, and the roller mounting plate is compressed and stored in the indentation under the action of the spring, so that the roller is hidden in the side of the inner box body, without affecting the tight fit between the inner box body and the outer box body, thereby ensuring the integrity and structural compactness of the storage space of the suitcase; when the inner box body is moved out to the second state, the roller extends out of the indentation under the action of the spring elastic force, and the limit block switches to a protruding position, restricting the movement of the roller mounting plate toward the indentation, and stably locking the roller in the extended state, so that the inner box body can be easily moved by the roller, effectively reducing the difficulty of users carrying heavy objects, and improving the convenience and efficiency of taking and placing items. At the same time, the limiting function of the limit block prevents the roller from accidentally retracting during use, thereby ensuring the stability and safety of the carrying process, and enhancing the practicality and reliability of the suitcase.

[0010] Preferably, in the vehicle luggage box of the first aspect, the inner box body comprises: a main body portion with an opening at the top; a cover portion for covering the opening of the main body portion from the top; a hinge portion connected between one end of the cover portion and the main body portion, so that the cover portion can be opened and closed relative to the main body portion; and a locking portion arranged between the other end of the cover portion and the main body portion, so that the cover portion can be locked to the main body portion, wherein the cover portion comprises: a first cover, which is arranged on the side of the hinge portion and is in the shape of a hollow plate, thereby having a hollow inner cavity; a slide groove portion, which is arranged on the first end of the hinge portion and is in the shape of a hollow plate, thereby having a hollow inner cavity; and a slide groove portion. A cover is provided through the upper surface thereof and extends in a straight line along a sliding direction perpendicular to the rotating axis of the hinge portion; a second cover is provided on the locking portion side and is in the shape of a flat plate, and an end of the second cover on the side opposite to the locking portion is accommodated in the hollow inner cavity of the first cover; and a slider portion is provided protrudingly on the upper surface of the second cover and is inserted into and protrudes from the slide groove portion, wherein, as the slider portion moves along the slide groove portion in the sliding direction, the second cover enters into or moves out of the hollow inner cavity of the first cover.

[0011] According to the vehicle trunk with the above structure, its cover plate part can realize flexible expansion of the storage space and convenient closing. The settings of the hinge part and the locking part enable the cover plate part to be opened and closed stably and locked firmly to the body part, ensuring the safety of storing items in the inner box. With the hollow structure and the chute part of the first cover, in combination with the accommodating and inserting method of the second cover and the sliding guiding function of the slider part, users can, according to the actual storage needs, slide the slider part along the chute part to flexibly adjust the position of the second cover, realizing the telescopic movement of the second cover in the hollow inner cavity of the first cover, enhancing the adaptability of the inner box to items of different sizes, and improving the space utilization rate and the convenience of use of the vehicle trunk. For example, when small items need to be taken or placed, only need to retract the second cover into the hollow inner cavity of the first cover, without opening the cover plate part as a whole, and items can still be placed on the upper part of the first cover, which is convenient to operate; when large items need to be stored, rotate the cover plate part of the second cover inside the first cover around the hinge part, so that the entire opening of the body part of the inner box can be exposed, facilitating the placement of items. Moreover, since the second cover is retracted inside the first cover, even when rotating around the hinge part, the rotation radius is very small, and the requirement for the operation space is low.

[0012] Preferably, in the vehicle trunk described in the first aspect, the locking part of the inner box includes: a locking protrusion provided on the second cover, which protrudes from the edge of the second cover toward the body part side; and a locking recess provided on the body part, and the locking protrusion can be engaged with the locking recess; wherein, a cut groove part is provided at the end of the first cover on the side opposite to the hinge part, and when the second cover enters the hollow inner cavity of the first cover, the locking protrusion on the second cover is received in the cut groove part.

[0013] According to the vehicle trunk with the above structure, the cooperation between the locking protrusion and the locking recess in the locking part can, when the cover plate part closes the inner box, firmly lock the cover plate through the engaging structure, preventing the cover plate from accidentally opening during transportation and ensuring the safety of storing items; in addition, through the cut groove part, when the second cover is retracted into the hollow inner cavity of the first cover, the locking protrusion can be received therein, avoiding the interference caused by the protrusion being exposed, which not only ensures the flatness of the overall structure of the inner box, facilitating users to quickly and smoothly take and place small items, but also can, when needed, slide the second cover to disengage the locking protrusion from the cut groove part and cooperate with the locking recess to realize the closing of the cover plate part for large items, enhancing the convenience and reliability of taking and placing items of different sizes in the inner box.

[0014] Preferably, in the vehicle trunk described in the first aspect, the other side of the inner box opposite to the one side has: a second indentation part that indents inward; and a pull ring part that is installed in the indentation part in a foldable manner. In addition, a pair of foldable handles are provided on the upper surface of the body part of the inner box on both sides opposite to each other.

[0015] According to the vehicle trunk with the above structure, the second indentation part and the foldable pull ring part provided on the side of the inner box body opposite to the indentation part provide a more convenient operation method for the user. When the inner box body is in the storage state, the pull ring part is folded and stored in the second indentation part, without occupying extra space, ensuring the overall regularity of the inner box body, facilitating the fitting with the outer box body and the placement of other items; through the handle above the main body part, when it is necessary to take in and out items, especially when moving the inner box body out of the outer box body for carrying, a pair of handles are unfolded, and the user can more labor-savingly pull or lift the inner box body through the handles. After the inner box body is taken out, the pull ring part is lifted, so that in the state where the rollers contact the ground, the inner box body can be effectively pushed by holding the pull ring part, effectively relieving the pressure borne by both hands, solving the problem that it is difficult to carry heavy items, making the process of taking in and out items easier and more efficient, and improving the convenience and comfort of using the vehicle trunk.

[0016] Preferably, in the vehicle trunk described in the first aspect, the main body part of the inner box body is configured to include an upper main body and a lower main body that can move relative to each other in the height direction. Among them, a groove part is provided on the peripheral wall of one of the upper main body and the lower main body, and the groove part recesses from the end of the peripheral wall facing the other of the upper main body and the lower main body and extends along the height direction; the peripheral wall of the other of the upper main body and the lower main body is inserted into the groove part. Among them, a plurality of positioning holes arranged in the height direction are provided on the peripheral wall where the groove part is formed, and the positioning holes penetrate from the inner surface of the peripheral wall to the groove part, so as to communicate with the groove part; among them, a recessed part, a spring connected to the bottom surface of the recessed part, and a positioning block connected to the end of the spring are provided on the inner surface of the peripheral wall inserted into the groove part. Among them, in the free state of the spring, the positioning block is stuck in the positioning hole, and the upper main body and the lower main body are stuck in the height direction; in the state where the spring is compressed under pressure, the positioning block is accommodated in the recessed part and thus completely disengages from the positioning hole, and the locking is released, and the upper main body and the lower main body can move relative to each other in the height direction until the positioning block is stuck in another positioning hole.

[0017] According to the vehicle luggage box with the above structure, the upper body and the lower body of the inner box body are relatively movable, and the groove part, the positioning hole, the recessed part, the spring and the positioning block are linked, which significantly improves the flexibility and adaptability of the storage space. When taking and placing items, when the user needs to store large or high items, by pressing the positioning block to compress the spring, the positioning block will be disengaged from the positioning hole, and the locking state of the upper and lower bodies will be released, and the upper body can be moved up in the height direction to expand the height of the inner box and easily accommodate large items; when storing small items, the upper body can be moved down to reduce the space of the inner box to prevent the items from shaking in the box. The cooperation of multiple arranged positioning holes and the positioning blocks can realize multi-level adjustment of the inner box height and accurately adapt to items of different sizes. At the same time, when the spring is free, the positioning block locks the positioning hole to ensure that the height of the inner box is fixed and prevent accidental changes in the height of the box during the process of taking and placing items. This not only improves the stability of item storage, but also facilitates users to quickly adjust the storage space according to actual needs, greatly improving the convenience and practicality of using the vehicle trunk.

[0018] Preferably, in the vehicle trunk of the first aspect, when the positioning block is locked with the first positioning hole which is the closest positioning hole to the cover plate among the plurality of positioning holes, the upper surface of the inner box is flush with the upper surface of the outer box.

[0019] According to the vehicle luggage box with the above-mentioned structure, in the storage state, the surfaces of the inner box body and the outer box body can be made flat and uniform, avoiding obstacles in taking and placing items due to height differences, making it convenient for users to quickly stack and store items and improving the smoothness of operation; in addition, the flat surface helps to optimize the space layout in the vehicle, reduce space waste, and facilitate the placement and fixation of other items, while also making the overall appearance of the luggage box more regular and beautiful.

[0020] Preferably, in the vehicle luggage box of the first aspect, positioning ribs are provided on the outer surface of the main body of the inner box body, and the positioning ribs protrude from the outer surface and extend along the height direction.

[0021] According to the vehicle luggage box having the above structure, the positioning ribs are arranged to enhance the contact friction between the inner box body and the outer box body, thereby preventing the inner box body from shaking and shifting due to bumps during driving, thereby ensuring the stability of the stored items.

[0022] Preferably, in the vehicle trunk of the first aspect, the vehicle trunk includes: a front trunk and / or a rear trunk.

[0023] According to the vehicle luggage box having the above-mentioned structure, it is commonly used in the front trunk and the rear trunk, which greatly improves the practicality and convenience of the front trunk and the rear trunk, and significantly optimizes the user's storage experience.

[0024] The second aspect of the present disclosure provides a vehicle, which includes the vehicle trunk described in the first aspect.

[0025] Since the vehicle in the second aspect adopts the vehicle trunk in the first aspect, corresponding various technical effects can also be achieved.

[0026] The vehicle trunk and vehicle according to the present disclosure have been generally described above. Details will be described below with reference to the accompanying drawings for easier understanding. BRIEF DESCRIPTION OF THE DRAWINGS

[0103] Hereinafter, the technical solutions of the present invention will be described more clearly by describing the specific embodiments of the present invention with reference to the accompanying drawings.

[0104] It should be noted that the drawings in the present invention are only schematic diagrams simply shown to clearly illustrate the parts related to the solution of the present invention, and do not show some non-essential parts that may exist. Therefore, these drawings should not be construed as limiting the present invention, and they may be different from the actual structure during use. Additionally, it should also be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., which may represent orientations or positions in the following description, are for the purpose of convenient explanation and are not restrictive. Similarly, for the sake of clarity and conciseness, the descriptions of well-known functions and structures are omitted below.

[0105] The vehicle trunk 1 of this embodiment is a storage space and is applicable to the front trunk and the rear trunk of the vehicle.

[0106] As Figures 1 - 11 shown, the vehicle trunk 1 of this embodiment includes an inner box body 100 and an outer box body 200. The outer box body 200 is provided as the main body of the vehicle trunk 1 on the vehicle body and can be regarded as a part of the vehicle body in a certain sense, and is also the main body of the traditional vehicle trunk without an inner box body. The inner box body 100 is a part independent of the outer box body 200, and it is installed inside the outer box body 200 in a removable manner, so as to have a first state ([ Figures 1 - 11 ) of being installed inside the outer box body 200 and a second state ([ Figures 12 - 22 ) of being removed from the outer box body 200.

[0107] As Figure 4 , Figure 6 , Figure 7 , Figure 8 etc. shown, one side of the inner box body 200 has an indented portion 130 that indents inward and a roller unit 140 provided on the indented portion 130. The roller unit 140 includes: a roller 141, a roller mounting plate 142 for mounting the roller 141, a spring 143 sandwiched and mounted between the roller mounting plate 142 and the bottom surface of the indented portion 130, a receiving hole 144 provided in the side surface of the indented portion 130, and a limiting block 145 that cooperates with the receiving hole 144. Regarding the limiting block 145, it can switch between a receiving position ([ Figure 7 ) of being received in the receiving hole 144 and a protruding position ([ Figure 23 ) of protruding from the receiving hole 144, so that in the first state of the inner box body 100, the limiting block 145 is in the receiving position, and the roller 141 of the roller unit 140 is received inside the indented portion 130 and is sandwiched between the inner box body 100 and the outer box body 200 (see Figure 7) and in the second state of the inner box body 100, the limit block 145 is in a protruding position to limit the movement of the roller mounting plate 142 pushed outwards from the retraction part 130 due to the elastic force of the spring 143 towards the retraction part 130, thereby clamping the roller 141 of the roller unit 140 in the extended state.

[0108] According to the vehicle trunk 1 of the present embodiment, through the outer box body 200 and the removable inner box body 100, in cooperation with the retraction part 130 on the side of the inner box body 100 and the roller unit 140, the dual technical effects of space utilization and convenient handling are achieved. In the first state, that is, when the inner box body 100 is used in a state of being fitted inside the outer box body 200, the roller unit 140 is received in the retraction part 130 and clamped between the inner and outer box bodies 100 and 200, without occupying additional storage space, ensuring the tight fit between the inner box body 100 and the outer box body 200, maintaining the overall structural compactness of the vehicle trunk 1, and effectively utilizing the vehicle space; in the second state, that is, when the inner box body 100 is removed from the outer box body 200 for separate use, the roller 141 of the roller unit 140 extends from the retraction part 130 and is clamped. The user can easily pull the inner box body 100, converting the heavy loaded items into rolling friction, greatly reducing the handling resistance, solving the problem that the user's hands have limited bearing capacity and inconvenient movement when handling heavy objects, significantly improving the efficiency of taking and placing items and the usability, and at the same time, the design of receiving (first state) and extending and clamping (second state) of the roller 141 by the retraction part 130 avoids the interference and wear of the roller 141 in the non-use state, as well as the accidental retraction of the roller 141 in the use state, improving the service life of the roller unit 140 and the overall usability reliability of the vehicle trunk 1.

[0109] In addition, for the roller unit 140 of the embodiments of the present disclosure, through the cooperative work of the roller 141, the roller mounting plate 142, the spring 143, the receiving hole 144, and the limiting block 145, the flexible switching and stable locking of the state of the roller 141 can be achieved. The spring 143 is clamped between the roller mounting plate 142 and the bottom surface of the indentation portion 130 to provide an elastic supporting force for the roller 141. In the first state, the limiting block 145 is received in the receiving hole 144, and the spring 143 is subjected to the extrusion force from the outer box body 200. Thus, the roller mounting plate 142 is compressed and received in the indentation portion 130 under the action of the spring, so that the roller 141 is hidden on the side of the inner box body 100, without affecting the tight fitting between the inner box body 100 and the outer box body 200, and ensuring the integrity of the storage space and the structural compactness of the luggage. When the inner box body 100 is moved out to the second state, the spring 143 is no longer restricted by the outer box body 200 and extends in the direction of elastic recovery. Thus, the roller 141 extends out of the indentation portion 130 under the elastic force of the spring 143. At this time, the limiting block 145 can be switched to the protruding position by operating the limiting block control portion 146 (to be described later), restricting the movement of the roller mounting plate 142 towards the indentation portion 130, and stably locking the roller 141 in the extended state, enabling the inner box body 100 to be easily moved through the rollers, effectively reducing the difficulty for the user to carry heavy objects, improving the convenience and efficiency of taking and placing items. At the same time, the limiting function of the limiting block 145 prevents the roller from accidentally retracting during use, ensuring the stability and safety of the handling process, and enhancing the practicability and reliability of the luggage.

[0110] As Figures 1 - 23 shown, the inner box body 100 of the embodiments of the present disclosure includes: a main body portion 110 with an opening at the top; a cover plate portion 120 for covering the opening of the main body portion 110 from above; a hinge portion 126 connected between one end of the cover plate portion 120 and the main body portion 110, enabling the cover plate portion 120 to open and close relative to the main body portion 110; and a locking portion 127 provided between the other end of the cover plate portion 120 and the main body portion 110, enabling the cover plate portion 120 to be locked to the main body portion 110. In this embodiment, to prevent the internal items from causing a large impact on the cover plate portion 120 during the movement of the inner box body 100, resulting in its deformation or damage, a material with a relatively high hardness can be selected to make the top cover plate, such as: glass fiber reinforced material (GFRP), etc. At the same time, a material with a buffer and energy absorption effect can be attached to the inner surface of the cover plate portion 120. In addition, as Figure 1 , Figure 2 , Figure 8 shown, in this embodiment, the locking portion 127 of the inner box body 100 is provided with 2, but the number is not limited. For example, it can also be more than 2, and of course, it can also be set to 1. However, to ensure the fastening strength, more than 2 is preferred.

[0111] As shown in the figure, in this embodiment, the cover plate portion 120 includes: a first cover 121 which is arranged on the hinge portion 126 side and is a hollow plate shape, thus having a hollow inner cavity; a chute portion 122 which is arranged through the upper surface of the first cover 121 and extends linearly along a sliding direction perpendicular to the rotation axis of the hinge portion 126; a second cover 124 which is arranged on the locking portion 127 side and is a flat plate shape, and an end portion of the second cover 124 on the side opposite to the locking portion 127 side is accommodated in the hollow inner cavity of the first cover 121; and a slider portion 125 which protrudes from the upper surface of the second cover 124 and is inserted into the chute portion 122 of the first cover 121 and protrudes from the chute portion 122. Wherein, as the slider portion 125 moves along the chute portion 122 in the sliding direction, the second cover 124 enters or exits from the hollow inner cavity of the first cover 121. As Figure 1 shown, a cut groove portion 123 is further arranged at the end of the first cover 121 on the side opposite to the hinge portion 126, and the position of the cut groove portion 123 is consistent with the position of the locking portion 127.

[0112] As Figure 1 , Figure 2 , Figure 8 , Figure 9 and so on shown, the locking portion 127 includes: a locking protrusion 128 arranged on the second cover 124, and the locking protrusion 128 protrudes from the edge of the second cover 124 towards the main body portion 110 side; and a locking recess 129 arranged on the main body portion 110, and the locking protrusion 128 can be locked in the locking recess 129. The locking structure of the locking protrusion 128 and the locking recess 129 can adopt the design of a snap lock, which is convenient for the user to manually open and lock. The cut groove portion 123 on the first cover 121 matches the shape and position of the locking protrusion 128, so that when the second cover 124 enters the hollow inner cavity of the first cover 121, the locking protrusion 128 on the second cover 124 is received in the cut groove portion 123. Through the cut groove portion 123, it is avoided that when the second cover 124 is pushed backward into the first cover 121, the locking protrusion 128 interferes with the edge of the first cover 121, resulting in the second cover 124 not being able to be completely pushed in.

[0113] In the vehicle trunk 1 of this embodiment, its cover plate portion 120 can achieve flexible expansion of the storage space for items and convenient enclosure. The settings of the hinge portion 126 and the locking portion 127 enable the cover plate portion 120 to be stably opened and closed and firmly locked to the main body portion 110, ensuring the storage safety of the inner box body 100; the hollow structure of the first cover 121 and the chute portion 122, in combination with the accommodating insertion method of the second cover 124 and the sliding guiding function of the slider portion 125, allow users to flexibly adjust the position of the second cover 124 according to actual storage needs by pushing the slider portion 125 to slide along the chute portion 122, realizing the telescopic movement of the second cover 124 within the hollow inner cavity of the first cover 121, enhancing the adaptability of the inner box body 100 to items of different sizes, and improving the space utilization rate and use convenience of the vehicle trunk. For example, when smaller items need to be taken or placed, the second cover 124 can be simply retracted into the hollow inner cavity of the first cover 121 without the need to open the entire cover plate portion 120, and items can still be placed on the upper part of the first cover 121, which is convenient to operate; when larger items need to be stored, the cover plate portion 120 of the second cover 124 inside the first cover 121 rotates around the hinge portion 126, so that the entire opening of the main body portion 110 of the inner box body 100 can be exposed, facilitating the placement of items. Moreover, since the second cover 124 is retracted inside the first cover 121, even when rotating around the hinge 126 portion, the rotation radius is very small, and the requirement for the operating space is low.

[0114] In addition, in the vehicle trunk 1 of this embodiment, the cooperation between the locking protrusion 128 and the locking recess 129 in the locking portion 127 can firmly lock the cover plate portion 120 through the latching structure when the cover plate portion 110 encloses the inner box body 100, preventing the cover plate portion 120 from accidentally opening during item transportation and ensuring the storage safety of items; the design of the cut groove portion 123 enables the locking protrusion 128 to be received therein when the second cover 124 is retracted into the hollow inner cavity of the first cover 121, avoiding interference caused by the protrusion being exposed. This not only ensures the flatness of the overall structure of the inner box body 100, facilitating users to quickly and smoothly take and place small items, but also enables the locking protrusion 128 to be disengaged from the cut groove portion 123 and cooperate with the locking recess 129 by sliding the second cover 124 when needed, realizing the enclosure of the cover plate portion 120 for large items, and enhancing the convenience and reliability of the inner box body 100 when taking and placing items of different sizes.

[0115] As Figure 4 、 Figures 18 - 19 、 Figures 21 - 22 shown, in the vehicle trunk 1 of this embodiment, the other side of the inner box body 100 opposite to the one side (i.e., the side forming the indentation portion 130 to accommodate the roller unit 140) has: a second indentation portion 160 that indents inward; and a pull ring portion 161 that is installed in the indentation portion 160 in a foldable manner. In addition, as Figures 1 - 5 、 Figures 8 - 11As shown in etc., a pair of foldable top handles 111 are provided on the upper surface of the main body portion 110 of the inner box body 100 on both sides opposite to each other.

[0116] The second indentation portion 160 and the foldable pull ring portion 161 provided on the other side of the inner box body 100 opposite to the indentation portion provide a more convenient operation method for the user. When the inner box body 100 is in the storage state, the pull ring portion 161 is folded and stored in the second indentation portion 160, without occupying extra space, ensuring the overall regularity of the inner box body 100, facilitating the fitting with the outer box body 200 and the placement of other items; in addition, through the pair of top handles 111 on the upper side of the main body portion 110, when it is necessary to take or place items, especially when moving the inner box body 100 out of the outer box body 200 for handling, the pair of top handles 111 are unfolded, and the user can more easily pull or lift the inner box body 100 through the top handles 111. After the inner box body 100 is taken out, the pull ring portion 161 is lifted, so that in the state where the rollers 141 are in contact with the ground, the inner box body 100 can be effectively pushed by holding the pull ring portion 161 by hand, effectively relieving the pressure borne by both hands, solving the problem of difficult handling of heavy items, making the process of taking and placing items more relaxed and efficient, and improving the convenience and comfort of using the vehicle trunk.

[0117] As Figure 4 、 Figure 5 、 Figure 10 、 Figure 11As shown in the figure, in the vehicle trunk 1 of the present embodiment, the main body portion 110 of the inner box body 100 is configured to include an upper main body 170 and a lower main body 180 that can move relative to each other in the height direction. The peripheral wall of one of the upper main body 170 and the lower main body 180, specifically the peripheral wall of the upper main body 170 in this embodiment, is provided with a groove portion 171. The groove portion 171 is recessed inward from the end of the peripheral wall of the upper main body 170 facing the lower main body 180 and extends along the height direction; the peripheral wall of the lower main body 180 is inserted into the groove portion 171. The peripheral wall of the upper main body 170 where the groove portion 171 is formed is provided with a plurality of positioning holes 172 arranged in the height direction as shown in the figure. The positioning holes 172 penetrate from the inner surface of this peripheral wall to the groove portion 171, so as to communicate with the groove portion 171. The positioning holes 172 are exemplified as 2 in this embodiment, but this is not restrictive, and there may be more than 3, and the distance between the positioning holes 172 can also be adjusted as needed. An indentation portion 181 is provided on the inner surface of the peripheral wall of the lower main body 180 inserted into the groove portion 171, a spring 182 connected to the bottom surface of the indentation portion 181, and a positioning block 183 connected to the end of the spring 182. Among them, in the free state of the spring 182, the positioning block 183 is locked in the positioning hole 172, and the upper main body 170 and the lower main body 180 are locked in the height direction; in the state where the positioning block 183 is pressed toward the indentation portion 181 so that the spring 182 is compressed under pressure, the positioning block 183 is accommodated in the indentation portion 181 and thus completely disengages from the positioning hole 172, so that the locking between the upper main body 170 and the lower main body 180 is released, and the upper main body 170 and the lower main body 180 can move relative to each other in the height direction until the positioning block 183 is locked in another positioning hole 172.

[0118] In the vehicle trunk 1 of this embodiment, different from the conventional trunk with a fixed capacity, the upper body 170 and the lower body 180 of the main body 110 of the inner box body 100 of the vehicle trunk 1 in this embodiment are connected by a relatively movable structure, and in cooperation with the linkage of the groove portion 171, the positioning hole 172, the recessed portion 181, the spring 182 and the positioning block 183, the flexibility and adaptability of the storage space are significantly improved. When taking and placing items, when the user needs to store large or tall items, by pressing the positioning block 182 to compress the spring 182, the positioning block 183 is disengaged from the positioning hole, and the locking state of the upper and lower bodies 170 and 180 is released, and the upper body 170 can be moved upward in the height direction to increase the height of the inner box body 100 and easily accommodate large items; when storing small items, the upper body 170 can be moved downward again to reduce the space of the inner box body and return it to the default height consistent with the outer box body 200. Even the upper body 170 can be moved downward continuously so that the inner box body 100 is lower than the outer box body to prevent the items from shaking in the box. The locking cooperation between the plurality of arranged positioning holes 172 and the positioning block 183 can realize multi-stage adjustment of the height of the inner box body, accurately adapt to different sizes of items. At the same time, in the free state of the spring 182, the positioning block 183 locks the positioning hole 172 to ensure that the height of the inner box body 100 is fixed and prevent accidental changes in the height of the box body during the process of taking and placing items. This not only improves the stability of item storage but also facilitates the user to quickly adjust the storage space according to actual needs, greatly enhancing the convenience and practicality of using the vehicle trunk.

[0119] Regarding the cooperation between the positioning hole 172 and the positioning block 183 between the upper body 170 and the lower body 180, as Figure 5 shown, in this embodiment, in the state where the positioning block 183 is locked with the first positioning hole 172 which is the closest to the cover plate portion 120 among the plurality of positioning holes 172, that is, the uppermost positioning hole 172, the upper surface of the inner box body 100 is flush with the upper surface of the outer box body 200. Accordingly, in the storage state, the surfaces of the inner box body 100 and the outer box body 200 can be made flat and unified, avoiding obstacles to item taking and placing caused by height differences, facilitating the user to quickly stack, store and retrieve items, and improving the operation fluency; in addition, the flat surface helps to optimize the layout of the vehicle interior space, reduce space waste, facilitate the placement and fixation of other items, and at the same time make the overall appearance of the trunk more regular and beautiful.

[0120] However, the cooperation between the positioning hole 172 and the positioning block 183 described above is not restrictive. When there are more than three positioning holes 172, it does not have to be the uppermost first positioning hole 172. When, for example, the lower second positioning hole or the like engages with the positioning block 183, the upper surface of the inner box body 100 can be flush with the upper surface of the outer box body 200. In this case, it is also possible to further lower the upper body 170 of the inner box body 100 relative to the lower body 180 so that the inner box body 100 can be lower than the outer box body 200.

[0121] As Figure 12 shown, etc., a positioning rib 190 is provided on the outer surface of the main body portion 110 of the inner box body 100 of the vehicle trunk 1 of this embodiment. The positioning rib 190 protrudes from the outer surface and extends along the height direction. Due to the arrangement of the positioning rib 190, the contact friction force between the inner box body 100 and the outer box body 200 is enhanced, preventing the inner box body 100 from shaking and shifting due to bumps during driving and ensuring the stability of article storage.

[0122] As Figure 17 , Figure 21 , Figure 29 shown, etc., a positioning protrusion 150 is provided on the lower surface of the inner box body 100. Correspondingly, a positioning recess 210 that cooperates with the positioning protrusion 150 is provided on the bottom surface of the outer box body 200. Through the cooperation between the positioning protrusion 150 and the positioning recess 210 between the inner box body 100 and the outer box body 200, the position of the inner box body 100 relative to the outer box body 200 can be reliably positioned, and even during vibrations during vehicle travel, etc., there will be no misalignment or shaking between the two.

[0123] In addition, instead of the above arrangement of this embodiment, it is also possible that a positioning recess is provided on the lower surface of the inner box body 100, and correspondingly, a positioning protrusion that cooperates with the positioning recess is provided on the bottom surface of the outer box body 200. In addition, the shapes of the positioning recess and the positioning protrusion are not limited to the cross shape in the figure and can also be other shapes, preferably shapes that can limit the position in both the front-rear and left-right directions.

[0124] Next, with reference to the attached Figure 2 , Figure 14 , Figure 20 , Figures 24 - 28 the stopper control portion 146 for controlling the movement of the stopper 145 of the roller unit 140 of this embodiment will be described. The stopper control portion 146 includes a slide switch 60, a slide piece 61, a stopper link chute 62, a slide piece card slot 63, a stopper main link 64, an anti-slip strip 65, a lateral link 66, a stopper sub-link 67, a fixed shaft 68, and a flexible link 69, wherein the ends of the stopper main link 64 and the flexible link 69 are connected to the stopper 145.

[0125] As shown in the figure, in this embodiment, the number of the sliding pieces 61 and the sliding piece slots 63 is both two, which are respectively arranged on both sides of the sliding switch 60 for guiding and restricting the movement of the sliding switch 60 in the vertical direction. In addition, the damping during the sliding process can be adjusted by designing the dimensional tolerances of the sliding pieces 61 and the sliding piece slots 63, so as to prevent the sliding switch 60 from sliding randomly. The anti-slip strip 65 is arranged on the lower side of the sliding switch 60 to prevent the sliding switch 60 from sliding back by itself after being pushed in one direction. The flexible link 69 connected to the limit block sub-link 67 via the fixed shaft 68 is mainly used to compensate for the variable distance between the lower end of the limit block sub-link 67 and the slider switch 60 when the limit block sub-link 67 makes a circular motion around the fixed shaft 68, that is: the thrust during the rotation of the limit block sub-link 67 can be better converted into the linear motion of the limit block 145.

[0126] Next, the operation mode of the limit block control mechanism 146 will be described. In the first aspect, when the inner box body 100 does not need to use the towing mode, that is, when the rollers 141 do not need to be extended, as shown in Figure 24 and Figure 27 , the slider switch 60 can be pushed along the limit block link chute 62 in a direction away from the roller 141 (the sliding piece 61 also slides along the sliding piece slot 63 accordingly). At this time, the slider switch 60 will drive the lower limit block main link 64 together with the limit block 145 connected below it to move (see Figure 25 ), so that the limit block 145 is retracted into the receiving hole 144. At the same time, the limit block main link 64 can drive the limit block sub-link 67 to rotate around the fixed shaft 68 through the lateral link 66, that is, the limit block sub-link 67 above the fixed shaft 68 will be pulled to move towards the roller 141, while the flexible link 69 below the fixed shaft 68 will move away from the roller 141 together with the limit block 145 connected below it, that is, the limit block 145 is also retracted into the receiving hole 144. On the other hand, when the inner box body 100 is taken out and the rollers 141 need to be used for the towing mode, at this time, the roller mounting plate 142 has been pushed outside the body part 110 under the action of the internal spring 143. In order to prevent the rollers 141 from being pushed back due to external forces, the sliding switch 60 needs to be manually pushed in a direction close to the roller 141. The operation mode of its internal link mechanism is the reverse movement of the first aspect described above, so that each limit block 145 can be moved out of the receiving hole 144 and fixed to the roller mounting plate 142, which will not be elaborated here.

[0127] The vehicle trunk 1 of the embodiments of the present disclosure has been described in detail above. It changes the traditional single storage structure into a double-layer detachable structure. Thus, when the occupant needs to carry multiple items on and off the vehicle at the same time, the inner box body 100 as the inner layer structure can be manually taken out as a whole and can be towed with one hand, which is convenient and labor-saving, improving the vehicle use experience of the occupant. In addition, the vehicle trunk of the present disclosure has relatively small changes to the structural design of current mass-produced vehicles, is easy to achieve mass production, and has a relatively low manufacturing cost.

[0128] Next, several typical usage scenarios of the vehicle trunk 1 of the embodiments of the present disclosure will be described for easier understanding.

[0129] <Normal usage scenario>

[0130] Referring to Figure 1 , during normal use, the inner box body 100 is placed inside the outer box body 200, and the cover plate portion 120 entirely seals the opening of the main body portion 110 of the inner box body 100, and the upper handle 111 folds down from the Figure 1 upright state and fits against the top surface of the inner box body.

[0131] At this time, items can be accommodated inside the inner box body 100, and at the same time, items can also be placed on the cover plate portion 120 of the inner box body 100.

[0132] <Usage scenario for taking and placing small items in the inner box body 100, etc.>

[0133] Referring to Figure 8 , when taking and placing small items in the inner box body 100, the slider portion 125 on the second cover 124 can be pushed so that the second cover 124 is received in the hollow space of the first cover 121. Thus, only the upper end opening of the main body portion 110 of the inner box body 100 needs to be semi-opened, and small items can be easily taken and placed, with simple operation. At this time, items can still be placed on the first cover 121 in the closed state.

[0134] <Usage scenario for taking and placing large items in the inner box body 100, etc.>

[0135] Referring to Figure 9 , when taking and placing large items in the inner box body 100, the cover plate portion 120 in which the second cover 124 is received in the hollow space of the first cover 121 can be rotated around the hinge portion 126. Thus, the upper end opening of the main body portion 110 of the inner box body 100 is fully opened, and large items can be easily taken and placed. At this time, since the flipped cover plate portion 120 can be in a state where the second cover is received inside the first cover, that is, the size of the flipped cover plate portion 120 is only the size of the first cover 121, the required flipping space is reduced. Even when the space above the cover plate portion 120 is limited or the operating space is limited, the cover can be easily flipped.

[0136] <Usage Scenario of Insufficient Storage Space in Inner Box 100>

[0137] Reference Figure 10 When the storage space in the inner box 100 is insufficient, the positioning block 183 can be pressed to both sides to make it enter the recessed part 181. At this time, the locking between the upper body 170 and the lower body 180 is released. The upper body 170 is moved upward relative to the lower body 180 until the positioning block 183 enters the required positioning hole 172 to lock the upper body 170 and the lower body 180 together again. Accordingly, the depth of the inner box 100 becomes deeper, increasing the storage space and solving the problem of insufficient storage space.

[0138] <Usage Scenario of Using Inner Box 100 Alone>

[0139] When it is necessary to carry the items in the inner box 100 from the vehicle to other places, etc., the inner box 100 can be taken out of the outer box 200 and the inner box 100 can be used alone for carrying the items.

[0140] At this time, as Figure 1 shown, first, check whether the locking part 127 between the cover part 120 and the body part 110 is reliably locked so that the locking part 127 is in a reliably locked state. Then, stand up the top handle 111 from the folded state. The user holds the top handle 111 with both hands, lifts the inner box 100 to disengage it from the outer box 200, and moves the inner box 100 out of the vehicle. The inner box 100 becomes an independently used storage box as Figures 12 - 23 shown.

[0141] At this time, since the spring 143 of the roller unit 140 is no longer restricted by the outer box 200, the spring 143 extends from the compressed state, and the roller 141 extends out of the outside of the body part 110. Next, operate the slide switch 60 of the limit block control part 146 and slide it in the direction of the roller 141, driving the limit blocks 145 to respectively change from the stored state stored in the corresponding storage holes 144 to the Figure 23 shown protruding state and engaging with the roller mounting plate 142 to prevent the roller 141 from retracting.

[0142] At this point, place the roller 141 on the ground position and stand up the pull ring part 161 in the second indentation part 160. Thus, the user can hold the pull ring part 161 and use the rolling friction between the roller 141 and the ground to tow the inner box 100, easily realizing the carrying of the items.

[0143] When it is necessary to carry items from other places to the vehicle, similar to the above operation, the items can be first placed in the inner box body 100, then towed to the vehicle, and then the sliding switch 60 of the limit block control part 146 is operated to slide it in a direction away from the roller 141, driving the limit blocks 145 to be respectively received in the corresponding receiving holes 144, releasing the clamping of the roller mounting plate 142. Then, by holding the top handle 111 by hand, the inner box body 100 is placed inside the outer box body 200, and the items can also be easily carried.

[0144] <Usage scenario of using the outer box body 200 alone>

[0145] When the inner box body 100 is used outside the vehicle, the outer box body 200 can also store items in the same way as a traditional single-vehicle trunk.

[0146] The above specific implementation manners do not constitute a limitation on the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
