[0043] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0044] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0045] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0046] Due to the presence of the lock body, lock core and lock buckle, traditional boxes often open in a direction away from the driver and passengers for ease of operation and passenger comfort. The problem is that the box needs to be opened at the rear of the car, and when there are passengers, the full-angle opening of the box cover requires the passengers to get off the car or maintain a specific posture. Based on the above problems, this patent aims to propose an embedded keyless opening structure. Since there is no external lock body, lock core and lock buckle, the opening direction of the box no longer needs to be restricted to the back of the driver and passengers. The specific implementation is as follows:

[0047] See also Figure 1-Figure 2 In an embodiment of the utility model, a tail box is proposed, including a box body 1 and a tail board 2, wherein the box body 1 can be detachably mounted on the tail board 2, and a mounting member 3 is provided at the bottom of the tail board 2, and the mounting member 3 is used to fix the tail board 2 on the vehicle body.

[0048] See also Figure 1-Figure 3 , Fig.10The detachable connection method of the box body 1 and the tail board 2 includes: the box body 1 and the tail board 2 are connected by a connecting component, wherein the connecting component includes:

[0049] At least four clamping columns 107 formed on the box body 1 and mounting holes 205 formed on the tail plate 2 and engaged with the clamping columns 107;

[0050] It also includes a second lock body 202 installed inside the tailgate 2 and a second lock buckle 106 detachably installed on the box body 1, wherein the second lock buckle 106 can pass through a through slot 206 formed on the tailgate 2 and be locked into the second lock body 202 when the box body 1 and the tailgate 2 move laterally.

[0051] The mounting hole 205 is a strip-shaped mounting hole, which is formed with an insertion position and a clamping position. A limit clamp 2051 is provided at the clamping position of the mounting hole 205 . An annular groove 1071 which is clamped and matched with the limit clamp 2051 is formed on the clamping column 107 .

[0052] In combination with the above features, the present embodiment describes in detail the specific connection method between the box body 1 and the tail plate 2, as follows:

[0053] After the tail plate 2 is fixed to the vehicle body, the four clamping columns 107 and the second lock buckle 106 on the box body 1 are inserted into the corresponding mounting holes 205 and the through grooves 206. At this time, the clamping column 107 is located at the insertion position, and the second lock buckle 106 is located at the inner side of the tail plate 2 and at the front end of the second lock body 202. At this time, the second lock body 202 is in the open state, and then the box body 1 is manually pushed to make the clamping column 107 slide from the insertion position to the clamping position, and the second lock buckle 106 moves toward the second lock body 202. When the clamping column 107 moves to the end of the stroke, the limiting clamping member 2051 is clamped into the annular groove 1071, and the second lock buckle 106 squeezes the second lock body 202, so that the second lock body 202 reaches the locked state, so as to lock the second lock buckle 106, thereby realizing the installation of the box body 1 and the tail plate 2. When it needs to be disassembled, it is only necessary to drive the second lock body 202 to the unlocked state.

[0054] It should be noted that when the second lock buckle 106 is locked into the second lock body 202, the lateral and longitudinal limitation of the box body 1 and the tail plate 2 is achieved, and the longitudinal limitation of the box body 1 and the tail plate 2 is further achieved by the set limiting card 2051 and the annular groove 1071, thereby improving the stability of the connection between the box body 1 and the tail plate 2.

[0055] Preferably, the tailgate 2 described above is composed of two shell structures, namely an upper shell and a lower shell, and the upper shell is detachably connected to the lower shell. Of course, the detachable connection method includes but is not limited to bolt connection. After the upper shell is connected to the lower shell, an installation cavity is formed on the inner side thereof, and the second lock body 202 is arranged in the installation cavity. When the second lock buckle 106 is inserted into the installation cavity, it is connected to the second lock body 202, thereby realizing the hidden setting of the second lock body 202 and the connection with the second lock buckle 106, which plays a certain protective role and eliminates the possibility of arbitrary human damage.

[0056] For further information, see Fig.11 , the second lock body 202 includes:

[0057] A second bracket 2021 is installed in the tail plate 2. Preferably, the second bracket 2021 is integrally formed with the tail plate 2, or

[0058] The second bracket 2021 can be detachably mounted in the tail plate 2, and the detachable mounting includes but is not limited to screw fixing;

[0059] A second movable limiting member 2022 rotatably mounted on the second bracket 2021 , wherein a second limiting groove 20221 is formed on the second movable limiting member 2022 ;

[0060] A second movable lock 2024 is rotatably mounted on the second bracket 2021, and a second limiting protrusion 20242 is formed on the second movable lock 2024. When the second lock body 202 reaches a locked state, the second limiting protrusion 20242 is placed in the second limiting groove 20221. The second movable lock 2024 is also formed with a second locking groove 20241 for the second lock buckle 106 to be placed therein;

[0061] The fourth spring 2023 connects the second movable limiting member 2022 and the second movable lock 2024 .

[0062] The second limiting groove 20221 and the second limiting protrusion 20242 are both arranged in an arc-shaped structure. When the second limiting protrusion 20242 is inserted into the second limiting groove 20221, the second movable lock 2024 is subjected to force, and the second movable limiting member 2022 has a tendency to rotate toward the second movable lock 2024.

[0063] In this embodiment, the fourth spring 2023 is installed between the second movable limiting member 2022 and the second movable lock 2024, so that the second movable limiting member 2022 and the second movable lock 2024 have a tendency to rotate towards each other. When the second movable limiting member 2022 is subjected to a force away from the second movable lock 2024, the second movable lock 2024 is also rotated in the rotation direction of the second movable limiting member 2022 under the elastic force of the fourth spring 2023. Since the second movable limiting member 2022 and the second movable lock 2024 are at different rotation centers, the second limiting member 2022 and the second movable lock 2024 are The protrusion 20242 and the second limiting groove 20221 are gradually separated until the second limiting protrusion 20242 is completely separated from the second limiting groove 20221. At this time, the second lock body 202 reaches the unlocked state. When the force of the second movable limiting member 2022 is removed, the second movable limiting member 2022 and the second movable lock 2024 rotate toward each other again under the reset force of the fourth spring 2023. However, at this time, the second limiting protrusion 20242 abuts against the side wall of the second movable limiting member 2022 and cannot enter the second limiting groove 20221 again, and is always in the unlocked state.

[0064] When the second lock buckle 106 moves toward the second lock body 202, it first enters the second lock groove 20241 and then generates an extrusion force on the second movable lock 2024. The second movable lock 2024 has a force to rotate toward the locked position, thereby squeezing the second movable limiting member 2022, so that the fourth spring 2023 is stretched until the second limiting protrusion 20242 is re-engaged in the second limiting groove 20221 to achieve a locked state.

[0065] See also Figure 10-11 A first driving source 203 is also provided on the inner side of the tail plate 2, and an output end of the first driving source 203 is connected to the second movable limiting member 2022 through a connecting member, so as to drive the second movable limiting member 2022 to rotate in a direction away from the second movable lock 2024.

[0066] Exemplary, in a specific implementation manner, the above-mentioned first driving source 203 is a first motor installed in the tailgate 2, a rotating wheel is fixed on the output shaft of the first motor, and the connecting member is a flexible connecting rope, one end of the flexible connecting rope is fixed on the rotating wheel, and the other end is fixed to the second movable limiting member 2022. When the first motor is working, it drives the rotating wheel to rotate, and when the rotating wheel rotates, the connecting rope is wound, thereby driving the second movable limiting member 2022 to rotate to meet the driving requirements.

[0067] Exemplarily, in a specific implementation manner, the first driving source 203 is an electric telescopic rod installed in the tailgate 2, and the connecting member is a flexible connecting rope, one end of the flexible connecting rope is fixed to the movable end of the electric telescopic rod, and the other end is fixed to the second movable limiting member 2022. When the electric telescopic rod performs a telescopic action, the second movable limiting member 2022 is driven to rotate to meet the driving requirements.

[0068] The above exemplary implementations are merely examples. In the specific implementation process, other structures may also be adopted, and this embodiment does not specifically limit this.

[0069] In order to facilitate the separation of the box body 1 and the tail plate 2, at least two embedded grooves 209 are formed on the inner side of the tail plate 2. An extrusion piece 207 is slidably arranged on the inner side of the embedded groove 209. One end of the extrusion piece 207 passes through the end of the embedded groove 209, and a fifth spring 208 is installed between the other end and the inner wall of the embedded groove 209. When the clamping column 107 moves to the clamping position, the extrusion piece 207 is squeezed, so that the fifth spring 208 is compressed. In the locked state with the second lock body 202, the fifth spring 208 remains compressed after being compressed. When the box body 1 needs to be removed, the fifth spring 208 releases its elastic potential energy only after the second lock body 202 reaches the unlocked state, thereby pushing the card column 107 and the box body 1 connected to the card column 107 as a whole until the card column 107 moves to the insertion position. At the same time, the extrusion piece 207 cooperates with the action of the fifth spring 208 to avoid the situation where the second lock buckle 106 cannot be separated from the second lock body 202.

[0070] As another embodiment of the present invention, please refer to Figure 1-Figure 9 , a key-free opening structure is also proposed, which is arranged on a box body 1, and the box body 1 includes a box box 102 and a box cover 101 hinged to the box box 102, specifically:

[0071] The key-free opening structure includes:

[0072] A first lock buckle 103 is installed in the box cover 101;

[0073] A first lock body 104 is installed in the box 102 and is used for the first lock buckle 103 to be locked into the first lock body 104 when the box cover 101 is covered on the box 102;

[0074] The slider assembly 105 is installed at the bottom of the box 102 and connected to the first lock body 104 through a pull rope. When the slider assembly 105 is triggered to move, the pull rope drives the first lock body 104 to move to release the locked state.

[0075] The box cover 101 and the box 102 include but are not limited to the box structure and box cover structure of the trunk, the box structure and box cover structure of the seat box, etc.

[0076] As can be seen from the above, the first lock buckle 103 and the first lock body 104 are both arranged on the inner side of the box body 1, and the opening direction of the box body 1 is no longer restricted by the passengers. There is no need to face away from the driver. The opening direction faces the driver and there is no need to go around the back of the car to open it. At the same time, the risk of the external lock being damaged can be eliminated to a certain extent.

[0077] For further information, see Figure 5-Figure 8 , the first lock body 104 includes:

[0078] A first bracket 1041 mounted on the inner wall of the box 102;

[0079] A first movable stopper 1042 rotatably mounted on the first bracket 1041 and connected to one end of the pull rope, wherein a first stopper groove 10421 is formed on the first movable stopper 1042;

[0080] A first movable lock 1044 is rotatably mounted on the first bracket 1041, and a first limiting protrusion 10442 is formed on the first movable lock 1044. When the first lock body 104 reaches a locked state, the first limiting protrusion 10442 is placed in the first limiting groove 10421;

[0081] The first spring 1043 connects the first movable limiting member 1042 and the first movable lock 1044 .

[0082] The first movable lock 1044 is also formed with a first locking groove 10441 for the first locking buckle 103 to be inserted into.

[0083] The first limiting groove 10421 and the first limiting protrusion 10442 are both arranged in an arc-shaped structure. When the first limiting protrusion 10442 is inserted into the first limiting groove 10421, the first movable lock 1044 is subjected to force, and the first movable limiting member 1042 has a tendency to rotate toward the first movable lock 1044.

[0084] The first lock body 104 described above has the same structure as the second lock body 202 described above, so the specific principle of the first lock body 104 will not be described in detail in this embodiment.

[0085] For further information, see Figure 3 , Fig. 9The slider assembly 105 includes a card box 1054 installed at the bottom of the box 102, and a receiving cavity is formed in the card box 1054; it also includes an installation box 1051 that is inserted into the receiving cavity, and a movable block 1052 is slidably installed in the installation box 1051, and an elastic reset member is provided between the movable block 1052 and the installation box 1051. Preferably, the elastic reset member includes a second spring 1053, and an extension column is formed at the end of the movable block 1052, and the extension column passes through the installation box 1051. The second spring 1053 is sleeved on the extension column, and the movable block 1052 is connected to the pull rope.

[0086] In this embodiment, the movable block 1052 is connected to the first movable limiter 1042 through a pull rope. When the movable block 1052 is subjected to force, it slides relative to the installation box 1051 and the card box 1054, thereby unlocking the first lock body 104 by pulling the rope. At the same time, the second spring 1053 is squeezed, so that the second spring 1053 reserves elastic potential energy. When the movable block 1052 loses its force, the second spring 1053 releases its elastic potential energy, thereby resetting the movable block 1052.

[0087] Preferably, a slide groove 10511 is formed on the installation box 1051, and a slider 10521 capable of directional sliding in the slide groove 10511 is formed on the movable block 1052. The sliding stability of the movable block 1052 is ensured by the sliding cooperation between the slider 10521 and the slide groove 10511.

[0088] The movable block 1052 is arranged in an L-shaped structure, and a section thereof perpendicular to the bottom of the box 102 passes through the through slot 10541 formed on the card box 1054, and can slide along the length direction of the through slot 10541. On this basis, the utility model also proposes a driving method for driving the directional movement of the movable block 1052, which is as follows:

[0089] This drive mode is implemented by active drive components, see Fig.10 , Fig.12 and Fig.13 The active driving member includes a mounting seat 2011 mounted in the tail plate 2 and an active movable member 2013 slidably mounted on the mounting seat 2011. The active movable member 2013 is arranged in an L-shaped structure, and a section thereof perpendicular to the tail plate 2 passes through the tail plate 2 and abuts against the movable block 1052. Preferably, an extension column is formed at one end of the active movable member 2013, the extension column passes through the mounting seat 2011, and a third spring 2012 is sleeved on the extension column, and two ends of the third spring 2012 abut against the active movable member 2013 and the mounting seat 2011 respectively;

[0090] It also includes a second driving source 204 installed in the tail board 2, and the movable end of the second driving source 204 is connected to the active movable part 2013 through a flexible connecting rope.

[0091] When the second driving source 204 is working, the active movable part 2013 is driven to move horizontally through the flexible connecting rope, and at the same time the third spring 2012 is squeezed, so that the third spring 2012 is compressed to store elastic potential energy. When the active movable part 2013 moves, the movable block 1052 is squeezed to move, thereby providing a force on the movable block 1052. When the second driving source 204 removes the driving force, the third spring 2012 is reset, thereby pushing the active movable part 2013 to the initial position.

[0092] Exemplarily, in a specific implementation manner, the second driving source 204 is a second motor installed in the tailgate 2, a rotating wheel is fixed on the output shaft of the second motor, one end of a flexible connecting rope is fixed on the rotating wheel, and the other end is fixed to the active movable part 2013, when the first motor is working, the rotating wheel is driven to rotate, and when the rotating wheel rotates, the connecting rope is wound, thereby driving the active movable part 2013 to rotate, so as to meet the driving requirements.

[0093] Exemplarily, in a specific implementation, the second driving source 204 is an electric telescopic rod installed in the tailgate 2, one end of the flexible connecting rope is fixed to the movable end of the electric telescopic rod, and the other end is fixed to the active movable part 2013. When the electric telescopic rod performs a telescopic action, the active movable part 2013 is driven to rotate to meet the driving requirements.

[0094] The above exemplary implementations are merely examples. In the specific implementation process, other structures may also be adopted, and this embodiment does not specifically limit this.

[0095] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0096] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
