Detailed Implementation

[0048] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0049] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0050] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0051] In this paper, the first direction Z, the second direction X, and the third direction Y are the directions that intersect each other.

[0052] This disclosure provides a vehicle. The vehicle can be a new energy vehicle, a hybrid vehicle, a traditional fuel vehicle, or other types of vehicles. The vehicle may include a body and a roof unit. The body has an interior roof with a roof panel. The roof unit can be mounted to the roof panel using fasteners (e.g., bolts, nails, pins, etc.) for placing objects, thereby improving the utilization of the vehicle's interior space.

[0053] See Figures 1-9 The top cabinet device may include a cabinet body 1, a fixing component 2, and a locking component 3. The fixing component 2 includes a connecting plate 21 and a fixing plate 22, which are fixedly connected to the connecting plate 21 and the top plate via bolts, welding, or other methods. The cabinet body 1 is movably mounted on the fixing plate 22 and has a storage cavity for placing items. The cabinet body 1 has an opening end that can move towards or away from the top plate. The locking assembly 3 is located at the opening end and includes a locking seat 31, a locking element, an operating element, and a stop bar 32. The locking seat 31 is installed at the opening end by bolt connection. The locking element includes a fixed locking tongue 33 and a movable locking tongue 34. The fixed locking tongue 33 is fixed to the locking seat 31. The stop bar 32 is connected to the connecting plate 21 and has a gap between it and the connecting plate 21. The movable locking tongue 34 has a locked state and an unlocked state. The operating element can drive the movable locking tongue 34 to move so that in the locked state, the movable locking tongue 34 and the fixed locking tongue 33 are connected to form a locking space, and the stop bar 32 passes through the locking space. In the unlocked state, the movable locking tongue 34 and the fixed locking tongue 33 are separated.

[0054] Thus, when the cabinet 1 needs to be opened while it is locked, the movable latch 34 can be driven to move by the operating component, so that the movable latch 34 is separated from the fixed latch 33. At this time, the movable latch 34 is in the unlocked state, and the movable latch 34 and the fixed latch 33 cannot form a locking space. Therefore, the movement of the stop bar 32 cannot be restricted. The opening end can move away from the top plate under the action of gravity or the action of human hand pulling until the cabinet 1 is opened to a suitable angle and then stops moving, so as to realize the opening of the cabinet 1 and facilitate the storage of items into the storage cavity. When cabinet 1 needs to be closed, the movable latch 34 can be driven to move by the operating component, so that the movable latch 34 is separated from the fixed latch 33. At this time, the movable latch 34 is in the unlocked state, and the movable latch 34 and the fixed latch 33 cannot form a locking space. A person can apply force to cabinet 1, so that the opening end moves towards the top plate until the stop bar 32 passes through the gap between the movable latch 34 and the fixed latch 33 and is located between the fixed latch 33 and the movable latch 34. At this time, the movable latch 34 and the fixed latch 33 are connected and form a locking space, so that the movable latch 34 is in the locked state, thereby restricting the movement of the stop bar 32, realizing the closure of cabinet 1, and preventing items in the storage cavity from falling out. The movable locking tongue 34 and the fixed locking tongue 33 form a locking space, allowing the stop bar 32 to pass through the locking space. Since the stop bar 32 is fixedly connected to the connecting plate 21, the cabinet 1 cannot move freely, so as to lock the cabinet 1 at once, which improves the stability and safety of the top cabinet device, thereby improving the reliability of the vehicle, facilitating the storage of items, and improving the utilization rate of the vehicle's internal space.

[0055] In one embodiment of this disclosure, the operating component can be manually operated by a person or automatically driven by a driving component, such as a motor or cylinder.

[0056] In one embodiment of this disclosure, when the movable latch 34 is in the locked state, the top plate contacts the cabinet 1, and the items in the storage cavity cannot fall out. It should be noted that the locked state refers to the state in which the movable latch 34 is in contact with the fixed latch 33 and forms a locking space, and the state in which the movable latch 34 is when the stop bar 32 passes through the locking space.

[0057] In one embodiment of this disclosure, the connection between the movable latch 34 and the fixed latch 33 can be understood as the movable latch 34 and the fixed latch 33 abutting against each other, or the movable latch 34 and the fixed latch 33 contacting each other.

[0058] In one embodiment of this disclosure, the number of fixing plates 22 can be multiple. For example, the number of fixing plates 22 can be two, three, four, five, etc., depending on specific needs, and is not limited herein. In one example, see [link to example]. Figure 4The number of fixing plates 22 can be two, which are spaced apart along the second direction X and symmetrically arranged about the plane formed by the first direction Z and the third direction Y. The cabinet body 1 is located between the two fixing plates 22, and the connecting plates 21 are fixedly connected to the two fixing plates 22 respectively. In this way, the stability of the top cabinet device can be improved by using two fixing plates 22.

[0059] In one embodiment of this disclosure, see Figure 2 , Figure 3 A protective plate 23 is bolted to the side of the fixed plate 22 away from the cabinet 1. The protective plate 23 can cover the side of the fixed plate 22 away from the cabinet 1 to provide protection and decoration for the fixed plate 22.

[0060] In one embodiment of this disclosure, see Figure 2 The fixed plate 22 may have a connector 24 on the side near the top plate. One end of the connector 24 is connected to the fixed plate 22 by bolts, and the other end can be connected to the top plate by bolts or snap-fit, so as to facilitate the connection between the top cabinet device and the top plate.

[0061] In one embodiment of this disclosure, see Figure 2 , Figure 5 The cabinet 1 includes a base plate 11 and side plates 12. The side plates 12 are connected to and surround the base plate 11, and the storage cavity is formed by the base plate 11 and the side plates 12. For example, the cabinet 1 is a lidless cube. The side plates 12 may include a left side plate, a right side plate, a front side plate, and a rear side plate. The left side plate, right side plate, front side plate, and rear side plate are integrally connected to the base plate 11, and the left side plate, right side plate, front side plate, and rear side plate are connected sequentially. The left side plate and right side plate are spaced apart along a second direction X, and the front side plate and rear side plate are spaced apart along a third direction Y to form the storage cavity of the cabinet 1. The connecting plate 21 is located on the side plate 12 away from the base plate 11.

[0062] In one embodiment of this disclosure, the storage cavity of the cabinet 1 is provided with a reinforcing beam 13, which surrounds the storage cavity. For example, see... Figures 2-5 There are four reinforcing beams 13, which are connected sequentially to form a rectangular closed shape. The four reinforcing beams 13 are each connected to the inner wall of the cabinet 1 by bolts. In this way, the reinforcing beams 13 increase the overall structural strength of the cabinet 1, thereby improving the stability and reliability of the top cabinet assembly.

[0063] In one embodiment of this disclosure, see Figure 2 , Figure 4The cabinet 1 is connected to the fixed plate 22 via the guide assembly 4 and can move along a specified trajectory. The specified trajectory can be a straight line trajectory, a curved trajectory, a broken line trajectory, or a combination of straight lines and curves. In this way, the guide assembly 4 can guide the movement trajectory of the cabinet 1, so that the cabinet 1 can open smoothly and improve the stability of the top cabinet device.

[0064] In one embodiment of this disclosure, see Figure 2 , Figure 4 The guide component 4 includes a first guide rail 41 and a first sliding part 42 that slidably engages with the first guide rail 41. The first guide rail 41 extends along a designated trajectory. The first guide rail 41 is located on one of the cabinet body 1 and the fixed plate 22, and the first sliding part 42 is located on the other of the cabinet body 1 and the fixed plate 22. In one example, the first guide rail 41 is located on the cabinet body 1, and the first sliding part 42 is located on the fixed plate 22. In another example, the first guide rail 41 is located on the fixed plate 22, and the first sliding part 42 is located on the cabinet body 1. Thus, the sliding engagement between the first sliding part 42 and the first guide rail 41 facilitates the opening and closing of the cabinet body 1 and improves the stability of the cabinet body 1's movement.

[0065] In one embodiment of this disclosure, see Figure 4 A first guide rail 41 is disposed on the side plate 12. The first guide rail 41 has a sliding groove structure and includes a straight portion 411 and a curved portion 412. The straight portion 411 extends in the third direction Y, and the curved portion 412 bends toward the connecting plate 21. The curved portion 412 is located on the side of the straight portion 411 away from the opening end and bends away from the straight portion 411. A first sliding portion 42 is disposed on the side of the fixing plate 22 near the side plate 12 and passes through the first guide rail 41. The first sliding portion 42 has a columnar structure to facilitate a smooth transition from the straight portion 411 to the curved portion 412. In one example, the first sliding portion 42 has a screw structure to facilitate the installation of the first sliding portion 42 with the fixing plate 22 and to facilitate quick engagement between the first sliding portion 42 and the first guide rail 41. Thus, when opening cabinet 1, the opening end can be pulled along the third direction Y first. Due to the action of the first guide rail 41, cabinet 1 is first translated by one end distance under the guidance of the straight part 411, and then rotated under the guidance of the curved part 412, so as to facilitate the smooth opening of cabinet 1, prevent cabinet 1 from moving randomly, and improve the safety and reliability of cabinet 1.

[0066] In one embodiment of this disclosure, see Figure 4The guide component 4 may further include a second guide rail 43 and a second sliding part 44 that slidably engages with the second guide rail 43. The second guide rail 43 extends in a third direction Y and is located on the side of the first guide rail 41 away from the top plate, and on the side of the first guide rail 41 away from the opening end. The second guide rail 43 is located on one of the cabinet body 1 and the fixed plate 22, and the second sliding part 44 is located on the other of the cabinet body 1 and the fixed plate 22. In one example, the second guide rail 43 is located on the cabinet body 1, and the second sliding part 44 is located on the fixed plate 22. In another example, the second guide rail 43 is located on the fixed plate 22, and the second sliding part 44 is located on the cabinet body 1. Thus, by sliding the second sliding part 44 with the second guide rail 43, the second sliding part 44 supports the cabinet body 1 during the opening and closing process, thereby improving the stability of the cabinet body 1.

[0067] In one embodiment of this disclosure, see Figure 4 The second guide rail 43 is disposed on the fixed plate 22. The second guide rail 43 has a sliding groove structure and extends along the third direction Y. It is located on the side of the first guide rail 41 away from the top plate and on the side of the first guide rail 41 away from the opening end. The second sliding part 44 is disposed on the side of the side plate 12 near the fixed plate 22 and passes through the second guide rail 43. The second sliding part 44 has a columnar structure so that when the first sliding part 42 is in the bent part 412, the second sliding part 44 can rotate in the guide rail to prevent jamming. In one example, the second sliding part 44 has a screw structure to facilitate the installation of the second sliding part 44 with the fixed plate 22 and to facilitate quick engagement between the second sliding part 44 and the second guide rail 43.

[0068] In one embodiment of this disclosure, see Figure 4 , Figure 5 A gear 121 is rotatably connected to the side plate 12 near the fixed plate 22. The fixed plate 22 is provided with a rack 221 extending in the third direction Y. When the first sliding part 42 is located in the straight part 411, the rack 221 meshes with the gear 121; when the first sliding part 42 is located in the curved part 412, the rack 221 disengages from the gear 121. In this way, through the meshing of the gear 121 and the rack 221, during the opening of the cabinet 1, the gear 121 and the rack 221 provide damping for the cabinet 1, preventing the cabinet 1 from being subjected to excessive force and causing a large impact on the first guide rail 41 and the second guide rail 43, thereby improving the service life of the top cabinet device.

[0069] In one embodiment of this disclosure, see Figure 4The side plate 12 has a receiving groove extending in the third direction Y. The receiving groove is located on the side of the second guide rail 43 away from the top plate, and the rack 221 is integrally connected to the side wall of the receiving groove away from the second guide rail 43. The gear 121 is located in the receiving groove and meshes with the rack 221. There is a gap between the side wall of the receiving groove opposite to the rack 221 and the gear 121. In this way, when the first sliding part 42 slides along the curved part 412, the gear 121 and the rack 221 can disengage, preventing the cabinet 1 from jamming and facilitating the smooth opening of the cabinet 1.

[0070] In one embodiment of this disclosure, see Figure 8 , Figure 9 The locking seat 31 has a placement cavity 311 extending along the first direction Z. A portion of the movable locking tongue 34 is located in the placement cavity 311 and can slide along the first direction Z. The operating member and the opening end are rotatably connected about the straight line containing the second direction X, and the movable locking tongue 34 can be in the unlocked state. In this way, the compactness of the locking assembly 3 can be improved and the space occupied by the locking assembly 3 can be reduced.

[0071] In one embodiment of this disclosure, see Figure 7 , Figure 8 , Figure 13 , Figure 14 The locking assembly 3 also includes an elastic element 35, which can be a spring, torsion spring, elastic sheet, or other structure. The elastic element 35 is located in the placement cavity 311 and can apply a force to the movable locking tongue 34 to move towards the connecting plate 21. In this way, the elastic element 35 allows the movable locking tongue 34 to mate with the fixed locking tongue 33 to form a locking space, facilitating the reset of the movable locking tongue 34.

[0072] In one embodiment of this disclosure, see Figure 8 , Figure 14 The movable latch 34 has a mounting groove 341, and the end of the elastic member 35 away from the bottom of the placement cavity 311 is disposed in the mounting groove 341. In this way, the mounting groove 341 helps to improve the connection strength between the elastic member 35 and the movable latch 34.

[0073] In one embodiment of this disclosure, see Figure 8 A fixing post 312 is integrally connected to the bottom of the placement cavity 311. The fixing post 312 extends along the first direction Z, and the elastic element 35 is sleeved on the fixing post 312. In this way, the fixing post 312 can prevent the elastic element 35 from shaking randomly, thus improving the stability of the elastic element 35.

[0074] In one embodiment of this disclosure, see Figure 9 , Figure 11The locking seat 31 has a guide groove 313 that extends along the first direction Z and communicates with the placement cavity 311. In one example, there are two guide grooves 313 arranged in parallel. In another example, there may be one guide groove 313. The movable locking tongue 34 is integrally connected to a guide block 342, which slides with the guide groove 313. Thus, the sliding engagement between the guide block 342 and the guide groove 313 facilitates the guidance of the movable locking tongue 34 along the first direction Z, thereby improving the stability of the locking assembly 3.

[0075] In one embodiment of this disclosure, see Figure 8 , Figure 9 , Figure 12 The operating components include an operating plate 36 and an abutment portion 361 located on the side of the operating plate 36 near the locking seat 31. The operating plate 36 and the locking seat 31 are rotatably connected about the line containing the second direction X. The abutment portion 361 extends into the placement cavity 311 and can rotate with the operating plate 36 to apply a force away from the connecting plate 21 to the movable locking tongue 34. In this way, a person can rotate the operating plate 36 with a small force, which can drive the abutment portion 361 to rotate, so that the abutment portion 361 applies a force away from the connecting plate 21 to the movable locking tongue 34, so that the movable locking tongue 34 separates from the fixed locking tongue 33, and puts the movable locking tongue 34 in the unlocked state. This facilitates the unlocking and opening of the cabinet 1, and the operation is simple and labor-saving.

[0076] In one embodiment of this disclosure, see Figure 8 , Figure 13 The movable locking tongue 34 has a groove 343 extending in the first direction Z on the side near the operating plate 36. The abutment portion 361 extends into the groove 343 and abuts against the movable locking tongue 34. In this way, the groove 343 can make the abutment portion 361 and the movable locking tongue 34 fit more stably, preventing the movable locking tongue 34 from disengaging from the abutment portion 361.

[0077] In one embodiment of this disclosure, see Figure 9 , Figure 10 , Figure 12 The operating plate 36 has a baffle 362 on the side near the locking seat 31, and the locking seat 31 has a stop 314 on the side near the operating plate 36. In the locked state, the stop 314 abuts against the baffle 362. Thus, when the movable latch 34 is reset under the action of the elastic member 35, it abuts against the baffle 362 through the stop 314, preventing excessive movement of the movable latch 34 and improving the reliability of the locking assembly 3.

[0078] In one embodiment of this disclosure, see Figure 9 , Figure 10The fixed latch 33 includes a fixed part 331 and a bent part 332 integrally connected. The end of the fixed part 331 away from the bent part 332 is fixedly connected to the locking seat 31. The bent part 332 bends toward the movable latch 34, and the movable latch 34 can connect with the side of the bent part 332 away from the fixed part 331.

[0079] In one embodiment of this disclosure, see Figure 6 , Figure 7 , Figure 8 The locking assembly 3 also includes a protective housing 37, which is fixedly connected to the opening end. The locking seat 31, the movable bolt 34, and the fixed bolt 33 are located inside the protective housing 37. In this way, the protective housing 37 can provide protection for the locking seat 31, the movable bolt 34, and the fixed bolt 33.

[0080] The working principle of the top cabinet device according to the present disclosure will be explained below.

[0081] In the locked state, when cabinet 1 needs to be opened, the operator can rotate the control panel 36. The control panel 36 drives the abutment part 361 to rotate synchronously. The abutment part 361 applies a force to the movable latch 34 to move away from the connecting plate 21, so that the movable latch 34 moves away from the connecting plate 21 under the action of the guide block 342, compressing the elastic element 35 to separate the movable latch 34 from the fixed latch 33. At this time, the movable latch 34 is in the unlocked state. The movable latch 34 and the fixed latch 33 cannot form a locking space, so the movement of the stop bar 32 cannot be restricted. The opening end can move along the first guide rail 41 and the second guide rail 43 under the action of gravity or the action of the operator's pulling force until the first sliding part 42 is located at the end of the curved part 412 away from the straight part 411. The cabinet 1 is opened to a suitable angle and stops moving, so as to realize the opening of the cabinet 1 and facilitate the storage of items into the storage cavity. During the opening of cabinet 1, gear 121 meshes with rack 221 and rotates on rack 221, which can buffer the force on cabinet 1 during opening, avoid cabinet 1 from having a large impact on first guide rail 41 and second guide rail 43, and improve the stability and service life of top cabinet device.

[0082] When cabinet 1 needs to be closed, the operator can rotate the control panel 36. The control panel 36 drives the abutment part 361 to rotate synchronously. The abutment part 361 applies a force to the movable locking tongue 34 to move away from the connecting plate 21, causing the movable locking tongue 34 to move away from the connecting plate 21 under the action of the guide block 342. This compresses the elastic element 35, separating the movable locking tongue 34 from the fixed locking tongue 33. The movable locking tongue 34 and the fixed locking tongue 33 can no longer form a locking space, and the operator can apply force to cabinet 1, causing cabinet 1 to move along the first guide rail 41 and the second guide rail 43. When the stop bar 32 passes through the gap between the movable latch 34 and the fixed latch 33 and is located between the fixed latch 33 and the movable latch 34, and the first sliding part 42 is located at the end of the straight part 411 away from the curved part 412, the operator releases the operating plate 36. Under the action of the elastic member 35, the movable latch 34 moves closer to the connecting plate 21 until the movable latch 34 connects with the fixed latch 33 and forms a locking space, so that the movable latch 34 is in a locked state to restrict the movement of the stop bar 32, realize the closing of the cabinet 1, and prevent the items in the storage cavity from falling out. During the process of the elastic element 35 pushing the movable locking tongue 34 to move, since the human hand does not apply force to the operating plate 36, the movable locking tongue 34 will cause the abutment part 361 to rotate. The abutment part 361 drives the operating plate 36 to rotate synchronously, and the operating plate 36 drives the baffle 362 to rotate synchronously. The direct stop block 314 abuts against the baffle 362, so that the movable locking tongue 34 stops moving, preventing the movable locking tongue 34 from moving excessively and disengaging from the placement cavity 311, thus improving the practicality of the locking assembly 3.
