Description
Technical Field
[0001] The present application relates to the technical field of vehicle trunks, and in particular to a vehicle modular trunk system. Background Art
[0002] A car trunk is a multifunctional storage and expansion device used inside the rear compartment of a car. After installing the car trunk, the originally irregular and underutilized space can be made regular, and at the same time, items can be stored inside the trunk, effectively avoiding damage to items caused by bumpy driving. Most car trunks generally adopt an upper and lower layered structure to meet the needs of different users. At the same time, in order to ensure the stability of the connection between the boxes, adjacent upper and lower boxes are equipped with a locking structure to achieve a stable connection.
[0003] The locking structure in the prior art usually uses a lock tongue and a spring for locking. When locking, the upper box is placed on the lower box, and the spring is compressed with the help of the protrusion of the lower box. At this time, the lock tongue bounces into the lock hole under the elastic force of the locking spring; when unlocking, the user needs to overcome the weight of the upper box and the items inside to make the lock tongue pop out. This unlocking process is relatively laborious for the user, especially when heavy items are placed in the trunk of the car. The user needs to apply greater force to unlock, which makes unlocking more difficult and reduces the convenience of the user when unlocking, which is obviously insufficient. Utility Model Content
[0004] In order to reduce the difficulty of unlocking a vehicle trunk and improve user convenience, the present application provides a vehicle modular trunk system.
[0005] The present application provides a vehicle-mounted modular trunk system that adopts the following technical solutions:
[0006] The lock assembly comprises a first locking box and a second locking box, wherein the locking box has a first locking slot and a second locking block that engages with the locking slot. The lock assembly comprises a lock box arranged on the first locking box, a lock slot is provided inside the lock box, a lock block is provided on the second locking box and engages with the lock slot, a receiving slot is provided on the lock block, an inner side wall of the receiving slot is provided with a sliding slot along the horizontal direction, and a lock tongue is slidably connected to the sliding slot, the lock slot has a snapping slot that engages with the lock tongue, and a spring is provided in the receiving slot, one end of the spring is provided on the lock tongue, and the other end is provided on the inner side wall of the receiving slot. When the spring is in a natural state, the lock tongue is engaged in the snapping slot, and a pulling assembly is provided in the lock block to pull the lock tongue in a horizontal direction.
[0007] By adopting the above technical solution, when unlocking, the user pulls the lock tongue horizontally by pulling the assembly to move it in the direction away from the card slot. When the lock tongue is completely out of the card slot, the user slightly lifts the second box body upwards to make the lock block out of the lock slot. At this time, the first box body and the second box body are unlocked. This arrangement allows the user to only pull the lock tongue horizontally by pulling the assembly when unlocking. The unlocking process does not require the user to overcome gravity to do work to make the lock block pop out. The entire unlocking process is no longer hindered by gravity, which effectively reduces the difficulty of unlocking the car trunk and improves user convenience.
[0008] Optionally, the pulling assembly includes a pulling frame hinged on the locking tongue, the rotating shaft of the pulling frame is rotatably connected in the accommodating groove, a drawstring is provided on the pulling frame, and a through hole for the drawstring to pass through is opened on the second box body.
[0009] By adopting the above technical solution, when unlocking, the user pulls the drawstring in the direction away from the second box body, the drawstring drives the pulling frame to rotate, and the pulling frame drives the lock tongue to move until it disengages from the card slot. The setting of the pulling assembly allows the user to unlock the lock block from the outside, which is convenient for the user to operate. At the same time, the pulling frame, drawstring and lock tongue constitute a lever-like system. The longer drawstring can effectively reduce the force applied by the user to pull the lock tongue out of the card slot, thereby further reducing the difficulty of unlocking the car trunk and improving the convenience of the user.
[0010] Optionally, a guide column is provided on the lock tongue, and the spring is sleeved on the outer surface of the guide column.
[0011] By adopting the above technical solution, the setting of the guide column ensures that the spring can accurately extend and retract along the axial direction of the guide column, guiding the elastic force of the spring, thereby ensuring that the lock block maintains a linear motion state in and out of the card slot when unlocking and locking, preventing the lock block from deflecting or getting stuck, thereby ensuring the smooth progress of the entire locking and unlocking action.
[0012] Optionally, a limiting column coaxially arranged with the guide column is provided in the accommodating groove, and one end of the spring away from the guide column is sleeved on the outer surface of the limiting column. When the locking tongue is disengaged from the clamping groove, the end of the guide column abuts against the limiting column.
[0013] By adopting the above technical solution, the expansion and contraction range of the spring is effectively limited through the cooperation of the limit column and the guide column, avoiding excessive expansion and contraction of the spring beyond the normal working range due to factors such as excessive external force, resulting in deformation and elastic failure, thereby improving the service life of the spring in frequent use environments.
[0014] Optionally, the cross-section of the locking groove is V-shaped, and when the locking block is clamped inside the locking groove, the outer surface of the locking block fits tightly against the inner side wall of the locking groove.
[0015] By adopting the above technical solution, the V-shaped lock groove guides the movement of the lock block. When the lock block is inserted into the lock groove, the lock block naturally slides along the V-shaped side wall of the lock groove and finally abuts against the bottom wall inside the lock groove. The friction between the lock block and the lock groove is increased by the V-shaped inclined surface, thereby improving the locking effect of the locking assembly. At the same time, when the vehicle is bumpy, the contact force between the lock block and the lock groove can be evenly dispersed along the V-shaped side wall, avoiding stress concentration and causing damage to the lock box, thereby improving the stability of the locking assembly.
[0016] Optionally, a first mounting groove for installing the lock box is provided on the first box body, and the bottom surfaces at two opposite ends of the lock box are fixedly connected to the outer surface of the first box body by welding; a second mounting groove for installing the lock block is provided on the second box body, and the opposite end surfaces of the lock block are fixedly connected to the outer surface of the second box body by welding.
[0017] By adopting the above technical solution, the opening of the first mounting groove and the second mounting groove provides a specific installation position for the lock block and the lock box, while reducing the space occupied by the lock block and the lock box, thereby improving the space utilization inside the first box body and the second box body. At the same time, the structural strength of the locking assembly on the trunk box body is improved by installing the lock block and the lock box by welding, ensuring that the locking assembly will not malfunction due to loose connection during long-term use, thereby effectively ensuring the stability of the connection of the locking assembly.
[0018] Optionally, the locking block includes a base plate, a cover plate and a mounting plate, the accommodating groove is opened on the surface of the base plate, the cover plate is detachably connected to the base plate by bolts, the sliding groove is formed by the bottom surface of the cover plate and the bottom wall of the accommodating groove, the mounting plate and the base plate form an avoidance groove for the pulling frame to rotate, and the mounting plate is detachably connected to the base plate by bolts.
[0019] By adopting the above technical solution, the arrangement of the cover plate, base plate and mounting plate realizes the modular production of the lock block, thereby improving the flexibility of the lock block production. At the same time, when the internal structure of the lock block fails, the maintenance personnel can remove the bolts to separate the cover plate or mounting plate from the base plate, directly exposing the internal components. The maintenance personnel can easily replace or repair the damaged parts, thereby reducing the cost and time of maintenance.
[0020] Optionally, a rough layer is provided on the outer surface of the drawstring.
[0021] By adopting the above technical solution, the friction between the user's hand and the drawstring is increased by the rough layer, thereby reducing the possibility of slipping during the pulling process.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The present application provides a locking assembly and a pulling assembly. When unlocking, the user pulls the lock tongue horizontally by the pulling assembly to move it in a direction away from the engaging groove. When the lock tongue is completely out of the engaging groove, the user slightly lifts the second box upward to disengage the lock block from the lock groove. At this time, the first box and the second box are unlocked. This arrangement allows the user to unlock by only pulling the lock tongue horizontally by the pulling assembly. The unlocking process does not require the user to overcome gravity to make the lock block pop out. The entire unlocking process is no longer hindered by gravity, which effectively reduces the difficulty of unlocking the car magic box and improves user convenience.
[0024] 2. This application provides a guide post and a limit post. The guide post ensures that the spring can accurately extend and retract along the axis of the guide post, guiding the elastic force of the spring. The cooperation between the limit post and the guide post effectively limits the extension and retraction range of the spring, preventing excessive extension and retraction of the spring beyond the normal operating range due to factors such as excessive external force, resulting in deformation and elastic failure. This extends the service life of the spring under frequent use.
[0025] 3. This application provides a modular locking block. When a fault occurs in the internal structure of the locking block, maintenance personnel can remove the bolts and separate the cover plate or mounting plate from the base plate, directly exposing the internal components. Maintenance personnel can easily replace or repair the damaged parts, reducing maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-6 This application is described in further detail.
[0034] An embodiment of the present application discloses a vehicle-mounted modular trunk system.
[0035] Reference Figure 1 A vehicle-mounted modular trunk system includes a first box body 1 and multiple second boxes 2. In this embodiment, the number of second boxes 2 is two, and the second boxes 2 are arranged above the first box body 1. The first box body 1 and each second box body 2 are connected through multiple locking components 3. In this embodiment, the number of locking components 3 is four, and the four locking components 3 are respectively arranged at the four corners of the second box body 2.
[0036] In order to meet the diverse usage needs of users, users can set a first box body 1 on two second box bodies 2 through the locking component 3, and at the same time, a second box body 2 can be set separately on each second box body 2. In this embodiment, two second boxes 2 are stacked on a first box body 1 as an example. At the same time, users can install modules such as refrigerators, insulation boxes, and storage baskets on the surface of the first box body 1 or the second box body 2.
[0037] Reference Figure 2 and Figure 3 The locking assembly 3 includes a lock box 31 welded on the surface of the first box body 1 facing the second box body 2, a first installation groove 101 for installing the lock box 31 is opened on the first box body 1, a lock groove 4 is opened inside the lock box 31, and a lock block 32 that engages with the lock groove 4 is welded on the surface of the second box body 2 facing the first box body 1, and a second installation groove 201 for installing the lock block 32 is opened on the second box body 2.
[0038] Reference Figure 2 and Figure 3 The cross section of the locking groove 4 is V-shaped. When the locking block 32 is clamped inside the locking groove 4, the outer surface of the locking block 32 fits tightly against the inner wall of the locking groove 4.
[0039] When locking, the second box body 2 is placed above the first box body 1 and ensure that the locking block 32 is aligned with the locking groove 4. Then the user cancels the force on the second box body 2. During the process of inserting the locking block 32 into the locking groove 4, the locking block 32 naturally slides along the V-shaped side wall of the locking groove 4 and finally abuts against the inner bottom wall of the locking groove 4. The friction between the locking block 32 and the locking groove 4 is increased by the V-shaped inclined surface, thereby improving the locking effect of the locking assembly 3. At the same time, when the vehicle is bumpy, the contact force between the locking block 32 and the locking groove 4 can be evenly dispersed along the V-shaped side wall, avoiding stress concentration and causing damage to the lock box 31, thereby improving the stability of the locking assembly 3.
[0040] Reference Figure 3 and Figure 4 The lock block 32 is provided with a receiving groove 5, and the inner wall of the receiving groove 5 is provided with a sliding groove 51 along the horizontal direction. The sliding groove 51 is slidably connected to the lock tongue 33. The inner wall of the lock groove 4 is provided with a clamping groove 41 that is engaged with the lock tongue 33. A spring 34 is provided inside the receiving groove 5, and one end of the spring 34 is fixedly connected to the outer surface of the lock tongue 33, and the other end is fixedly connected to the inner wall of the receiving groove 5. In the natural state of the spring 34, the lock tongue 33 is clamped in the clamping groove 41, and a pulling component 6 for pulling the lock tongue 33 in the horizontal direction is provided in the lock block 32.
[0041] Reference Figure 3 and Figure 4 The pulling assembly 6 includes a pulling frame 61 hinged on the outer surface of the lock tongue 33, and the rotating shaft of the pulling frame 61 is rotatably connected between the opposite inner walls of the accommodating groove 5. The end of the pulling frame 61 is fixedly connected with a drawstring 62. A penetration hole 202 for the drawstring 62 is opened on the second box body 2. The pulling end of the drawstring 62 extends through the penetration hole 202 to the outer surface of the second box body 2. The outer surface of the drawstring 62 is provided with a rough layer. In this embodiment, the rough layer is a hard velvet layer. The rough layer increases the friction between the user's hand and the drawstring 62, thereby reducing the possibility of slipping during the pulling process.
[0042] When locking, the user first aligns the locking block 32 on the second box body 2 with the locking groove 4 on the first box body 1, and then cancels the force applied to the second box body 2. Under the guidance of the V-shaped locking groove 4, the weight of the second box body 2 pushes the locking tongue 33 to move away from the engaging groove 41. At this time, the spring 34 is compressed. When the end of the locking block 32 abuts against the inner bottom wall of the locking groove 4, the locking tongue 33 aligns with the engaging groove 41, the pressure on the spring 34 disappears, and the spring 34 resets to drive the locking block 32 to engage inside the engaging groove 41. At this time, the locking work of the first box body 1 and the second box body 2 is completed;
[0043] When unlocking, the user pulls the drawstring 62 in the direction away from the second box body 2, and the drawstring 62 drives the lock tongue 33 to move in the direction away from the engaging groove 41 through the pulling frame 61. When the lock tongue 33 is completely out of the engaging groove 41, the user slightly lifts the second box body 2 upward to make the lock block 32 out of the lock groove 4. At this time, the first box body 1 and the second box body 2 are unlocked. This arrangement allows the user to only pull the lock tongue 33 in the horizontal direction by pulling the pulling assembly 6 when unlocking. The unlocking process does not require the user to overcome gravity to do work to make the lock block 32 pop out. The entire unlocking process is no longer hindered by gravity, which effectively reduces the difficulty of unlocking during vehicle running-in and improves the convenience of the user. At the same time, the pulling frame 61, the drawstring 62 and the lock tongue 33 constitute a lever-like system. The longer drawstring 62 can effectively reduce the force applied by the user to pull the lock tongue 33 out of the engaging groove 41, thereby further reducing the difficulty of unlocking the vehicle trunk and improving the convenience of the user.
[0044] Reference Figure 4 and Figure 5 The end of the lock tongue 33 away from the sliding groove 51 is fixedly connected to the guide column 7, and the inner side wall of the accommodating groove 5 away from the sliding groove 51 is fixedly connected to the limiting column 8. The axes of the limiting column 8 and the guide column 7 are on the same straight line. A spring 34 is provided inside the accommodating groove 5, and the spring 34 is sleeved between the limiting column 8 and the guide column 7. Under the restriction of the guide column 7 and the limiting column 8, the expansion and contraction range of the spring 34 is limited, which avoids the excessive expansion and contraction of the spring 34 due to factors such as excessive external force and exceeds the normal working range, resulting in deformation and elastic failure, thereby improving the service life of the spring 34 under frequent use environments.
[0045] During the unlocking and locking process, the guide column 7 and the limit column 8 effectively ensure that the spring 34 can accurately extend and retract along the axial direction of the guide column 7, guiding the elastic force of the spring 34, thereby ensuring that the lock block 32 maintains a linear motion state in and out of the card slot 41 when unlocking and locking, preventing the lock block 32 from deflecting or getting stuck.
[0046] Reference Figure 5 and Figure 6 The locking block 32 includes a base plate 321, a cover plate 322 and a mounting plate 323. The accommodating groove 5 is opened on the surface of the base plate 321. The cover plate 322 is detachably connected to the base plate 321 by bolts 9. The sliding groove 51 is formed by the bottom surface of the cover plate 322 and the inner side wall of the accommodating groove 5. The mounting plate 323 and the base plate 321 form an avoidance groove for the rotation of the rotating shaft part of the pulling frame 61. The mounting plate 323 is detachably connected to the base plate 321 by bolts 9.
[0047] The arrangement of the cover plate 322, the base plate 321 and the mounting plate 323 realizes the modular production of the locking block 32 and improves the flexibility of the production of the locking block 32. At the same time, when a component inside the locking block 32 fails, the maintenance personnel can remove the bolts 9 to separate the cover plate 322 or the mounting plate 323 from the base plate 321, directly exposing the internal components. The maintenance personnel can easily replace or repair the damaged components, reducing the cost and time of maintenance.
[0048] The implementation principle of the vehicle-mounted modular trunk system of the present application embodiment is as follows: when locking, the user first aligns the locking block 32 on the second box body 2 with the locking groove 4 on the first box body 1, and then cancels the force applied to the second box body 2. Under the guidance of the V-shaped locking groove 4, the weight of the second box body 2 pushes the locking tongue 33 to move away from the engaging groove 41. At this time, the spring 34 is compressed. When the end of the locking block 32 abuts against the inner bottom wall of the locking groove 4, the locking tongue 33 aligns with the engaging groove 41, the pressure on the spring 34 disappears, and the spring 34 resets to drive the locking block 32 to engage inside the engaging groove 41. At this time, the locking work of the first box body 1 and the second box body 2 is completed;
[0049] When unlocking, the user pulls the drawstring 62 in the direction away from the second box body 2, and the drawstring 62 drives the lock tongue 33 to move in the direction away from the card slot 41 through the pulling frame 61. When the lock tongue 33 is completely out of the card slot 41, the user slightly lifts the second box body 2 upward to make the lock block 32 out of the lock slot 4. At this time, the first box body 1 and the second box body 2 are unlocked. This arrangement allows the user to only pull the lock tongue 33 in the horizontal direction by pulling the component 6 when unlocking. The unlocking process does not require the user to overcome gravity to do work to make the lock block 32 pop out. The entire unlocking process is no longer hindered by gravity, which effectively reduces the difficulty of unlocking during vehicle-mounted running-in and improves user convenience.
[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
