[0052] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. The same components are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0053] like Figure 1 The figure shows a system schematic diagram of a vehicle trunk depth adjustment system according to an embodiment of the present invention, comprising: a trunk body 1, a trunk front wall 2, a driving module 3, an image recognition device 4 and a controller (not shown in the figure), the trunk front wall 2 and the image recognition device 4 are accommodated in the trunk body 1, the trunk body 1 is provided with an opening 11, the image recognition device 4 is communicatively connected to the input end of the controller, the output end of the controller is communicatively connected to the driving module 3, the driving module 3 is connected to the trunk front wall 2, and under the control of the controller, drives the trunk front wall 2 to move toward or away from the opening 11.

[0054] Specifically, an opening 11 is formed at the end of the trunk body 1 .

[0055] In some embodiments, a trunk sill plate 12 is fixedly mounted on the end of the trunk body 1 , and a tailgate 13 is mounted on the opening 11 .

[0056] The trunk body 1 contains a trunk front wall 2 and an image recognition device 4 .

[0057] The two sides of the trunk front wall 2 are respectively fixedly connected to the two side support plates 21. The front of the trunk box body 1 is a rear seat, such as a second row of seats. The height of the trunk front wall 2 is lower than the rear seat backrest 7 or the coat rack. The top of the rear seat backrest 7 is installed with a rear seat headrest 8.

[0058] The trunk front wall 2 is connected to the driving module 3 , and the driving module 3 is controlled by a controller. The controller controls the driving module 3 to drive the trunk front wall 2 to move toward or away from the opening 11 according to the signal of the image recognition device 4 or other signals in the vehicle.

[0059] The trunk depth refers to the size of the trunk along the front-to-back direction of the vehicle. More specifically, the distance between the trunk front wall 2 and the opening 11 is the trunk depth. Preferably, the distance between the trunk front wall 2 and the trunk sill plate 12 is the trunk depth. By adjusting the distance between the trunk front wall 2 and the opening 11, the trunk depth can be adjusted.

[0060] The image recognition device 4 is a camera installed in the trunk box 1. In some embodiments, the image recognition device 4 is a binocular camera installed on the top inner plate of the trunk box 1.

[0061] The image recognition device 4 is in communication with the controller, and the controller obtains the image in the trunk box 1 taken by the image recognition device 4, and uses the existing 3D recognition system and the existing neural network deep learning technology to recognize the image in the trunk box 1. Its functions are:

[0062] 1. After the tailgate is opened, it is used to identify the trunk depth change program start gesture: when the user needs the trunk depth to be reduced, the camera collects the customer's specific gesture image and is recognized by the 3D recognition system. At this time, the trunk depth change program is started, and the trunk front wall 2 moves toward the rear of the vehicle (i.e., toward the opening 11);

[0063] 2. Used to collect the distribution image of items in the trunk, and the 3D recognition system identifies the front-to-back distance between the item and the opening 11 (preferably the front-to-back distance between the item and the trunk sill 12), and then converts it into the rearward movement stroke of the trunk front wall 2 to prevent the stored items from hitting the trunk sill;

[0064] 3. When the user needs to customize the trunk depth, it is used to collect the position image of the user's hand. The 3D recognition system analyzes, stores and memorizes the position of the hand and calculates the rearward movement of the front wall 2 of the trunk to meet the personalized needs of different percentiles for the depth of picking and placing.

[0065] The vehicle trunk depth adjustment system of the present invention controls the driving module through a controller to drive the front wall of the trunk to move towards or away from the trunk box opening, thereby being able to adjust the trunk depth according to user needs and providing convenience to the user.

[0066] In one embodiment, it also includes a trunk floor located at the bottom of the trunk body 1, the trunk floor includes a trunk depth adjustment floor 5 and a trunk height adjustment floor 6, the trunk front wall 2 is fixedly connected to the trunk depth adjustment floor 5, and the driving module 3 includes a depth-direction telescopic mechanism for driving the trunk depth adjustment floor 5 to move toward or away from the opening 11, and a height-direction telescopic mechanism for driving the trunk height adjustment floor 6 to move up and down in the height direction of the trunk body 1.

[0067] Specifically, the trunk floor includes a trunk depth adjustment floor 5 fixedly connected to the trunk front wall 2 and a trunk height adjustment floor 6 near the opening 11. The trunk floor is composed of a plurality of floor units.

[0068] In some embodiments, the trunk floor includes multiple floor units. When the trunk depth is not adjusted, one or more continuous floor units near the opening 11 or near the trunk threshold 12 are combined into a trunk height adjustment floor 6, and the remaining floor units are combined into a trunk depth adjustment floor 5. The trunk front wall 2 is fixedly connected to the trunk depth adjustment floor 5.

[0069] The driving module 3 includes a depth-direction telescopic mechanism for driving the trunk depth-adjusting bottom plate 5 to move toward or away from the opening 11 , and a height-direction telescopic mechanism for driving the trunk height-adjusting bottom plate 6 to move up and down in the height direction of the trunk box body 1 .

[0070] Preferably, the driving module 3 is an electric telescopic control module, comprising an electric telescopic rod device in the depth direction and an electric telescopic rod device in the height direction, wherein the electric telescopic rod device in the depth direction serves as a depth direction telescopic mechanism, and the electric telescopic rod device in the height direction serves as a height direction telescopic mechanism.

[0071] In some embodiments, one end of the electric telescopic rod device in the depth direction is fixed to the vehicle body, and the electric telescopic rod of the electric telescopic rod device in the depth direction is fixedly connected to the trunk front wall 2 or the trunk depth adjustment base plate 5. The extension of the electric telescopic rod of the electric telescopic rod device in the depth direction will drive the trunk depth adjustment base plate 5 together with the trunk front wall 2 to move toward the opening 11, and the contraction of the electric telescopic rod of the electric telescopic rod device in the depth direction will drive the trunk depth adjustment base plate 5 together with the trunk front wall 2 to move away from the opening 11.

[0072] In some embodiments, one end of the height direction electric telescopic rod device is fixed to the bottom of the trunk height adjustment bottom plate 6, and the electric telescopic rod of the height direction electric telescopic rod device is fixedly connected to the trunk height adjustment bottom plate 6. The electric telescopic rod of the height direction electric telescopic rod device contracts to drive the trunk height adjustment bottom plate 6 to move downward, and the electric telescopic rod of the height direction electric telescopic rod device extends to drive the trunk height adjustment bottom plate 6 to move upward.

[0073] Therefore, the initial state of the trunk is Figure 2-3 As shown, the driving module 3, the tailgate 13 and the trunk sill plate 12 are not shown. Figure 4-5 As shown, the electric telescopic rod of the electric telescopic rod device in the height direction is retracted, driving the bottom plate unit to move downward, wherein the drive module 3, the tailgate 13 and the trunk sill plate 12 are not shown. Figure 6-7 As shown, the extension of the electric telescopic rod of the electric telescopic rod device in the depth direction drives the trunk depth adjustment base plate 5 together with the trunk front wall 2 and the support plates 21 on both sides of the trunk front wall 2 to move backward, wherein the drive module 3, the tailgate 13 and the trunk sill plate 12 are not shown.

[0074] In this embodiment, by providing a trunk height adjustment bottom plate and a trunk depth adjustment bottom plate, the front wall of the trunk and the trunk depth adjustment bottom plate move simultaneously, ensuring that the objects in the trunk move as a whole and maintain their positions unchanged during the change of the trunk depth.

[0075] like Figure 8 The flowchart of the adjustment method of the vehicle trunk depth adjustment system as described above is shown in one embodiment of the present invention, including:

[0076] Step S801, in response to a depth adjustment request, obtaining a required depth defined by a user;

[0077] Step S802, determining the adjustment depth according to the required depth;

[0078] Step S803, controlling the trunk front wall 2 to move toward the opening 11 to the adjustment depth;

[0079] Step S804 , when the image recognition device 4 recognizes the depth reset gesture, the trunk front wall 2 is controlled to move away from the opening 11 to an initial depth.

[0080] Specifically, the present invention can be applied to electronic devices with processing capabilities, such as the controller of the aforementioned vehicle trunk depth adjustment system.

[0081] When a depth adjustment request is detected, step S801 is triggered, and in response to the depth adjustment request, a user-defined required depth is obtained.

[0082] In some embodiments, when the tailgate is opened, the depth adjustment request is triggered, that is, when the tailgate is opened, step S801 is triggered, and in response to the depth adjustment request, the required depth defined by the user is obtained.

[0083] Then, step S802 is executed to determine the adjustment depth according to the required depth.

[0084] In some embodiments, the desired depth is used as the adjustment depth.

[0085] In some embodiments, the desired depth is combined with other parameters to determine the adjustment depth.

[0086] Then, step S803 is executed to control the trunk front wall 2 to move toward the opening 11 to the adjusted depth.

[0087] Specifically, the driving module 3 drives the front wall 2 of the trunk to move toward the opening 11 to the adjusted depth.

[0088] Then, after taking the object, the user uses a specific depth reset gesture in the trunk box 1 to trigger step S804. When the image recognition device 4 recognizes the depth reset gesture, the trunk front wall 2 is controlled to move away from the opening 11 to the initial depth.

[0089] Specifically, when the user needs to reset the trunk, a specific gesture is used, the gesture is captured by the image recognition device 4, and recognized by the 3D recognition system. When the depth reset gesture is recognized, the driving module 3 drives the trunk front wall 2 to move away from the opening 11 to the initial depth, for example, driving the trunk front wall 2 to move to the front end of the trunk body 1, and the trunk returns to its initial state.

[0090] In this embodiment, when a user takes or places small-sized items, the depth of the trunk becomes shorter, making it easier to take or place items. After taking or placing items, the depth of the trunk returns to its original position without affecting the taking or placing of other items.

[0091] like Fig. 9 The flowchart of the adjustment method of a vehicle trunk depth adjustment system in another embodiment of the present invention includes:

[0092] Step S901, responding to a depth adjustment request.

[0093] Step S902: if there is a pre-saved requirement depth, obtaining the pre-saved requirement depth;

[0094] If the required depth is not saved, a human gesture in the trunk is detected. When the image recognition device 4 recognizes that the human gesture is a depth change gesture, the distance between the human gesture in the trunk body 1 and the opening 11 of the trunk body 1 is taken as the required depth and saved.

[0095] Step S903, obtaining a distribution image of the trunk items in the trunk box body 1 recognized by the image recognition device 4;

[0096] According to the distribution image, determining the shortest distance between the trunk object and the opening 11 as the object depth;

[0097] When the object depth is less than the required depth, determining the adjusted depth to be the object depth;

[0098] When the object depth is greater than or equal to the required depth, the adjusted depth is determined to be the required depth.

[0099] Step S904 , controlling the trunk front wall 2 to move toward the opening 11 to the adjustment depth.

[0100] Step S905, when it is detected that the distribution image of the trunk objects changes, updating the object depth according to the changed distribution image;

[0101] updating the adjustment depth according to the updated depth of the object;

[0102] The trunk front wall 2 is controlled to move toward the opening 11 to the updated adjustment depth.

[0103] Step S906 , when the image recognition device 4 recognizes the depth reset gesture, the trunk front wall 2 is controlled to move away from the opening 11 to an initial depth.

[0104] Specifically, when the user needs to adjust the depth of the trunk, a depth adjustment request is generated, and step S901 is executed to respond to the depth adjustment request.

[0105] Among them, the depth adjustment request can be triggered by the tailgate opening event, or by the user clicking the depth adjustment button in the vehicle computer, or by the user operating the depth adjustment button in a mobile phone that is connected to the vehicle for communication.

[0106] After responding to the depth adjustment request, it is determined whether there is a pre-saved required depth, and step S902 is performed. If there is a pre-saved required depth, the pre-saved required depth is obtained;

[0107] If the required depth is not saved, a human gesture in the trunk is detected. When the image recognition device 4 recognizes that the human gesture is a depth change gesture, the distance between the human gesture in the trunk body 1 and the opening 11 of the trunk body 1 is taken as the required depth and saved.

[0108] The required depth may be a predefined depth or a depth preset by the system.

[0109] In some embodiments, after the tailgate is opened, if there is a pre-saved required depth, the pre-saved required depth is obtained from the memory. If the required depth is not saved, the image recognition device 4 detects the human gesture in the trunk, and when the 3D recognition system recognizes that the human gesture is a depth change gesture, the distance between the human gesture in the trunk box 1 and the opening 11 of the trunk box 1 is taken as the required depth and saved.

[0110] After the required depth is determined, step S903 is executed to obtain a distribution image of the trunk items in the trunk box body 1 recognized by the image recognition device 4;

[0111] According to the distribution image, determining the shortest distance between the trunk object and the opening 11 as the object depth;

[0112] When the object depth is less than the required depth, determining the adjusted depth to be the object depth;

[0113] When the object depth is greater than or equal to the required depth, the adjusted depth is determined to be the required depth.

[0114] Specifically, the image recognition device 4 of the trunk top interior panel collects the trunk item distribution image, and the 3D recognition system recognizes the shortest distance between the trunk item and the opening 11 as the item depth. Preferably, the 3D recognition system recognizes the shortest distance between the trunk item and the trunk sill plate 12 as the item depth.

[0115] In some embodiments, the shortest distance between the trunk item and the opening 11 is converted into the number of floor units without items stored therein, thereby calculating the maximum travel of the trunk depth without the items hitting the rocker panel.

[0116] Then, the item depth is compared with the required depth to determine whether the item depth can meet the required depth of the user's needs. When the item depth is greater than or equal to the required depth, the required depth can be met, and the adjusted depth is determined to be the required depth. When the item depth is less than the required depth, the required depth cannot be met, and the adjusted depth is determined to be the item depth.

[0117] Then, step S904 is executed to control the trunk front wall 2 to move toward the opening 11 to the adjustment depth.

[0118] Specifically, the control driving module 3 drives the trunk front wall 2 to move to the rear of the vehicle to the adjusted depth.

[0119] Specifically, when the item depth is greater than or equal to the required depth, the required depth can be met, and the adjustment depth is determined to be the required depth, and the control driving module 3 drives the trunk front wall 2 to move to the rear of the vehicle to the required depth. When the item depth is less than the required depth, the required depth cannot be met, and the adjustment depth is determined to be the item depth, and the control driving module 3 drives the trunk front wall 2 to move to the rear of the vehicle to the item depth, that is, the maximum achievable position.

[0120] When the object near the rocker panel is taken out, the distribution image of the trunk object changes, which triggers the execution of step S905. When the distribution image of the trunk object changes, the object depth is updated according to the changed distribution image.

[0121] updating the adjustment depth according to the updated depth of the object;

[0122] The trunk front wall 2 is controlled to move toward the opening 11 to the updated adjustment depth.

[0123] If the updated item depth is greater than or equal to the required depth, the required depth can be met, and the adjusted depth is determined to be the required depth, and the control driving module 3 drives the trunk front wall 2 to move to the rear of the vehicle to the required depth. If the updated item depth is less than the required depth, the required depth cannot be met, and the adjusted depth is determined to be the updated item depth, and the control driving module 3 drives the trunk front wall 2 to move to the rear of the vehicle to the item depth.

[0124] In some embodiments, the number of floor units included in the trunk depth adjustment floor 5 is determined according to the hand length of a certain percentile of the population.

[0125] Since the number of bottom plate units included in the trunk depth adjustment bottom plate 5 limits the length of the trunk depth adjustment bottom plate 5 along the front-rear direction of the vehicle, that is, limits the maximum adjustable length of the trunk front wall 2, it is determined according to the hand length of a certain percentile population to meet the needs of more users, so that most users can determine the required depth by adjusting the position of their hands.

[0126] When the user needs to reset the trunk, the user uses a specific depth reset gesture in front of the image recognition device 4, which is recognized by the 3D recognition system and triggers step S906. When the image recognition device 4 recognizes the depth reset gesture, the trunk front wall 2 is controlled to move away from the opening 11 to the initial depth.

[0127] This embodiment recognizes user gestures through an image recognition device, determines the required depth defined by the user based on the user gestures, and simultaneously determines the item depth of the trunk objects by identifying the distribution of items in the trunk. By comparing the item depth with the required depth, damage to objects in the trunk during trunk depth adjustment is avoided.

[0128] In one embodiment, the vehicle trunk depth adjustment system further includes a trunk floor located at the bottom of the trunk body 1, the trunk floor includes a trunk depth adjustment floor 5 and a trunk height adjustment floor 6, the trunk front wall 2 is fixedly connected to the trunk depth adjustment floor 5, the driving module 3 includes a depth direction telescopic mechanism for driving the trunk depth adjustment floor 5 to move toward or away from the opening 11, and a height direction telescopic mechanism for driving the trunk height adjustment floor 6 to move up and down in the height direction of the trunk body 1;

[0129] The controlling the trunk front wall 2 to move toward the opening 11 to the adjustment depth includes:

[0130] Controlling the height-direction telescopic mechanism to drive the trunk height-adjusting bottom plate 6 to move downward;

[0131] Control the depth direction telescopic mechanism to drive the trunk depth adjustment bottom plate 5 to drive the trunk front wall 2 to move toward the opening 11 to the adjustment depth;

[0132] The controlling the trunk front wall 2 to move away from the opening 11 to an initial depth includes:

[0133] Control the depth direction telescopic mechanism to drive the trunk depth adjustment bottom plate 5 to drive the trunk front wall 2 to move away from the opening 11 to an initial depth;

[0134] The height-direction telescopic mechanism is controlled to drive the trunk height-adjusting bottom plate 6 to move upward to be in the same plane as the trunk depth-adjusting bottom plate 5 .

[0135] Specifically, when it is necessary to control the trunk front wall 2 to move toward the opening 11 to an adjusted depth, as shown in FIG. Figure 4 and Figure 5 As shown, the height adjustment bottom plate 6 of the trunk is first driven downward by the height direction telescopic mechanism, and then Figure 6 and Figure 7 As shown, the trunk depth adjustment bottom plate 5 is driven to drive the trunk front wall 2 and the two side support plates 21 to move to the adjustment depth in the direction close to the opening 11 through the depth direction telescopic mechanism. When the trunk is reset, the depth direction telescopic mechanism is controlled to drive the trunk depth adjustment bottom plate 5 to drive the trunk front wall 2 and the two side support plates 21 to move forward to the initial depth. In some embodiments, the initial depth is the front end of the trunk body 1. Then, the height direction telescopic mechanism is controlled to drive the trunk height adjustment bottom plate 6 to move up to the original height position, and be located in the same plane as the trunk depth adjustment bottom plate 5.

[0136] In this embodiment, by providing a trunk height adjustment bottom plate and a trunk depth adjustment bottom plate, the front wall of the trunk and the trunk depth adjustment bottom plate move simultaneously, ensuring that the objects in the trunk move as a whole and maintain their positions unchanged during the change of the trunk depth.

[0137] like Fig.10 The workflow of image recognition of the best embodiment of the present invention is shown, including:

[0138] Step S1001, the image recognition device 4 collects: human gestures, finger positions, and images of the placement and distribution of items in the trunk;

[0139] Step S1002, the 3D recognition system analysis and calculation platform performs analysis and calculation on the collected image;

[0140] Step S1003 , the driving module 3 of the trunk depth adjustment system receives a signal.

[0141] Specifically, in this embodiment, a 3D recognition system is used and a neural network deep learning technology is applied. The analysis and calculation platform analyzes the human gestures, finger positions and the distribution images of the items in the trunk collected by the camera, determines when to start the trunk depth change program and calculates the trunk depth change displacement, and transmits the signal to the driving module 3.

[0142] like Fig.11 The flowchart of the trunk depth adjustment and depth position memory of the best embodiment of the present invention is shown, including:

[0143] Step S1101, the user sends a trunk depth change gesture;

[0144] Step S1102, the image recognition device 4 collects gesture images;

[0145] Step S1103, the 3D recognition system recognizes the gesture, memorizes the trunk depth required by the user, and recognizes and calculates the trunk depth change range;

[0146] Step S1104, the driving module 3 is started;

[0147] Step S1105, the trunk height adjustment bottom plate 6 is lowered, and the trunk front wall 2 and the trunk depth adjustment bottom plate 5 are moved backward;

[0148] Step S1106, the user takes or places an item;

[0149] Step S1107, the image recognition device 4 collects a trunk reset gesture image;

[0150] Step S1108, the trunk is reset.

[0151] In this embodiment, when the user needs to change the depth of the trunk, the user can put his hand deep into the trunk and use a specific gesture at the required depth position, fixed on the top inner plate of the trunk body 1, and the binocular camera of the image recognition device 4 captures the gesture, and the system starts the depth change program and the depth position memory function.

[0152] Specifically, the image recognition device 4 collects the trunk item distribution image, and the 3D recognition system recognizes the depth position of the front of the finger in the trunk, and the distance between the trunk item and the trunk threshold plate 12. This distance is converted into the number of floor units without items stored, so that the maximum travel of the trunk depth that can be changed without the items hitting the threshold plate can be calculated. This travel is compared with the depth position of the front of the finger in the trunk, so as to determine whether the movable travel can meet the depth position required by the user.

[0153] The depth position of the frontmost finger in the trunk is the required position, and the shortest distance between the trunk item and the trunk threshold plate 12 is the item depth.

[0154] If the required depth can be met, the driving module 3 is started to move the required trunk height adjustment bottom plate 6 downward, and the trunk depth adjustment bottom plate 5, the trunk front wall 2 and the support plates 21 on both sides of the front wall are moved back to the required depth;

[0155] If the required depth cannot be met, the trunk height adjustment bottom plate 6 that can be moved downward is moved downward, and the trunk depth adjustment bottom plate 5, the trunk front wall 2 and the support plates 21 on both sides of the front wall are moved backward to the maximum achievable position, that is, the item depth position. When the items near the trunk threshold plate 12 are taken out, the trunk depth adjustment bottom plate 5, the trunk front wall 2 and the support plates 21 on both sides of the front wall are continued to be moved backward to the required depth. At the same time, the 3D recognition system memorizes and stores the user's required depth position, that is, the required depth.

[0156] When the user needs to reset the trunk, a specific gesture is used, which is recognized by the 3D recognition system. The driving module 3 drives the bottom trunk depth adjustment base plate 5, the trunk front wall 2 and the support plates 21 on both sides of the front wall to move forward to the front end, and drives the trunk height adjustment base plate 6 to be lifted to the original height position, so that the trunk returns to its initial state.

[0157] In the present invention, when the user opens the trunk again, the 3D recognition system receives the trunk opening signal, retrieves the last stored user required trunk depth position, that is, the required depth, and the driving module 3 drives the trunk depth adjustment base plate 5, the trunk front wall 2 and the support plates 21 on both sides of the front wall to move back to the required depth.
