[0040] In the description of the present invention, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figures 1 to 3 As shown, the present application provides an adaptive handle for an electric suitcase, including a handle body 1 and an adjustment structure 2, the adjustment structure 2 includes a detection member 21 and a control module 22, the control module 22 can receive the signal of the detection member 21 and control the movement of the suitcase; the detection member 21 is provided with a slider 211 that can move relative to the detection member 21, and the detection member 21 can detect the relative position of the slider 211 on the detection member 21; the handle body 1 is also slidably connected to a first slider 3, the side of the first slider 3 close to the handle body 1 is connected to the slider 211, and the first slider 3 can drive the slider 211 to move.

[0042] In the present application, the first slide plate 3 drives the slider 211 to move, and then the relative position of the slider 211 on the detection member 21 is detected by the detection member 21 to determine the relative position between the user and the suitcase, thereby controlling the moving speed of the suitcase to ensure that the suitcase can move with the user, giving the user a better user experience.

[0043] The detection member 21 may also be a sliding potentiometer, and the slider 211 may change the resistance value of the sliding potentiometer connected to the control module 22, thereby changing the moving speed of the suitcase.

[0044] In other embodiments, the detection element 21 may also be a distance meter, which measures the distance moved by the slider 211 to determine the relative position between the suitcase and the user, thereby controlling the moving speed of the suitcase through the control module 22 .

[0045] An installation cavity is defined in the handle body 1 , and an installation groove 12 penetrating to the outside of the handle body 1 is defined on the inner wall of the installation cavity; a detection member 21 is embedded in the installation groove 12 , and a control module 22 is installed in the installation cavity.

[0046] Through the installation cavity, the adjustment structure 2 is integrated into the handle body 1 without affecting the overall structural strength of the handle body 1, which has better aesthetics; and when the user is pulling the suitcase, the hand is always on the handle. Integrating the adjustment structure 2 into the handle body 1 not only does not affect the user's grip feeling, but also can better judge the relative position between the user and the suitcase, ensuring a better user experience.

[0047] A plurality of concave curved grooves 31 arranged in a straight line are provided on the side of the first slide plate 3 facing away from the handle body 1 , and any two adjacent concave curved grooves 31 are connected by a convex transition curved surface portion 32 .

[0048] The concave curved groove 31 and the transition curved surface portion 32 provide a design that is more suitable for hand holding, allowing users to have a better grip and improving the user experience.

[0049] The handle body 1 is also connected to a second slide plate 4 , and two sides of the second slide plate 4 are connected to two sides of the first slide plate 3 , and the handle body 1 is wrapped between the second slide plate 4 and the first slide plate 3 .

[0050] The handle body 1 is wrapped by the first slide plate 3 and the second slide plate 4 , and the user holds the first slide plate 3 and the second slide plate 4 , so that the first slide plate 3 and the second slide plate 4 can move relative to the handle body 1 better.

[0051] In this embodiment, at least one of the first slide plates 3 and 4 is also connected to a return spring, and the middle part of the return spring is fixed to the handle body 1, so after the user lets go, the first slide block 3 and the second slide block 4 can automatically return to their initial positions, and the suitcase stops moving.

[0052] A pressing block 5 is also connected to the handle body 1, and the pressing block 5 is used to control the telescopic rod; the pressing block 5 is installed in the installation cavity, and the top of the installation cavity is provided with a through hole 13 that penetrates to the outside of the handle body 1, and a pressing portion 51 is provided on the pressing block 5, and part of the pressing portion 51 is located in the through hole 13.

[0053] The top surface of the pressing block 5 is higher than the top surface of the handle body 1. The second slide plate 4 is provided with a slide groove 41 for embedding the pressing block 5. The pressing block 5 can limit the moving stroke of the second slide plate 4, thereby avoiding excessive movement of the first slide plate 3 and the second slide plate 4, and ensuring that the slider 211 moves within the limited range of the detection member 21.

[0054] like Figure 4 As shown, a method for controlling movement of an electric luggage case is also provided according to the structure of the adaptive handle, comprising the following steps:

[0055] In response to a movement instruction of the electric trunk, movement information and preset information of the electric trunk are acquired, and a rotation speed of a driving motor is adjusted based on the movement information and the preset information, wherein the preset information includes preset movement control information of the electric trunk;

[0056] Acquire the relative position information between the electric suitcase and the user in real time, determine the relative position relationship between the electric suitcase and the user, and adjust the movement of the electric suitcase according to the relative position information;

[0057] A stop acceleration condition is formed based on preset movement control information of the electric trunk, and whether the movement of the electric trunk meets the demand is determined according to the stop acceleration condition.

[0058] The movement of the electric suitcase is controlled according to the relative position relationship between the electric suitcase and the user, ensuring that the electric suitcase can actively adapt to the user's walking, avoiding the user having to chase the suitcase or slow down to walk with the suitcase, and providing a better user experience.

[0059] Further, in another embodiment, in response to the movement instruction of the electric luggage case, obtaining the movement information and preset information of the electric luggage case, and adjusting the speed of the driving motor based on the movement information and the preset information, the method includes:

[0060] Detecting that the slider moves on the detection piece, obtaining the slider's stop position and recording the position as w;

[0061] The current moving state of the electric suitcase is obtained. If the electric suitcase is in a stationary state, the speed curve in the preset information is obtained, and the speed v is obtained on the speed curve corresponding to the stop position of the slider, and the electric suitcase is controlled to accelerate to the speed v. In the process of the electric suitcase moving from stationary to starting, the preset speed v is first obtained according to the position of the slider after movement, and the electric suitcase is directly accelerated to v according to the preset starting acceleration curve, thereby improving the reaction speed of the electric suitcase, reducing the time for users to wait for the electric suitcase to start, and providing users with a better user experience.

[0062] Among them, the speed curve includes the original speed curve and the optimized speed curve. The original speed curve is the speed curve obtained by the tester based on the analysis of test subjects of different heights. The original speed curve is only called when it is used for the first time; the optimized speed curve is obtained by optimizing the original speed curve based on the data collected each time the user uses it. It can better fit the user's usage habits. The electric suitcase can follow the user with a shorter reaction time and provide a better user experience.

[0063] If the electric trunk is in a uniform moving state, the acceleration curve in the corresponding area in the preset information is obtained, and the acceleration a is obtained on the acceleration curve corresponding to the position of the slider, and the electric trunk is controlled to move at the acceleration a.

[0064] Among them, the acceleration curve includes the original acceleration curve and the optimized acceleration curve. The original acceleration curve is the speed curve obtained by the tester based on the analysis of test subjects of different heights. The original acceleration curve is only called when it is used for the first time; the optimized acceleration curve is obtained by optimizing the original acceleration curve based on the data collected each time the user uses it. It can better fit the user's usage habits. The electric suitcase can accelerate with a shorter reaction time to keep up with the user and provide a better user experience.

[0065] Before the real-time acquisition of the relative position information between the electric luggage case and the user, the following steps are included:

[0066] A stop movement zone is set on the detection member, and two sides of the stop movement zone are defined as a first direction and a second direction, a first direction deceleration zone, a first direction uniform speed zone and a first direction acceleration zone are sequentially provided in the first direction of the stop movement zone along a direction away from the stop movement zone, and a second direction deceleration zone, a second direction uniform speed zone and a second direction acceleration zone are sequentially provided in the second direction of the stop movement zone along a direction away from the stop movement zone;

[0067] Based on the preset movement control information of the electric trunk, the accelerations of different positions of the first direction deceleration zone, the first direction acceleration zone, the second direction deceleration zone, and the second direction acceleration zone are set.

[0068] The initial position of the slider is located at the center of the detection part, so the slider can slide in two directions. It can adapt to whether the user pulls the electric suitcase with his left hand or right hand, which improves the versatility of the application. Users do not need to cater to the electric suitcase in order to use the electric suitcase, giving users a better user experience.

[0069] By setting a stop movement zone on the detection piece, and the position of the stop movement zone is located at the center of the detection piece; when the user is not using the electric suitcase, the slider is located in the stop movement zone, and the electric suitcase is in a stationary state; when the user suddenly lets go of the slider during the use of the electric suitcase, the slider will return to the stop movement zone under the action of the return spring and stop driving the electric suitcase, so that the electric suitcase will stop naturally under the action of friction, and the effect of stopping when the hands are released is achieved with a simple structure. The electric suitcase will not continue to drive forward, which has better safety; and the movement of the electric suitcase is not intervened by deceleration or braking, which can prevent the electric suitcase from tipping over, ensuring that users have a better use experience.

[0070] The step of acquiring the relative position information between the electric suitcase and the user in real time, determining the relative position relationship between the electric suitcase and the user, and adjusting the movement of the electric suitcase according to the relative position information includes:

[0071] The position of the slider on the detection part is obtained in real time, and the relative position of the user and the electric luggage case is analyzed according to the slider in different areas, and the acceleration direction of the electric luggage case is controlled according to the analysis results;

[0072] Based on the analysis result of the relative position between the user and the electric luggage case, the acceleration magnitude of the electric luggage case is adjusted.

[0073] In this embodiment, the position of the slider on the detection member can be accurately obtained through the change of the resistance value, thereby ensuring high detection accuracy, being able to respond to the speed change of the user in a shorter time, and better realizing the function of following the user.

[0074] Wherein, in analyzing the relative position of the user and the electric luggage case according to the slider in different areas, it includes

[0075] When the slider is in the first direction acceleration zone or the second direction acceleration zone, the electric luggage case is located behind the user in the user's forward direction relative to the user, and the electric luggage case is controlled to accelerate along the user's forward direction;

[0076] When the slider is in the first direction deceleration zone or the second direction deceleration zone, the electric luggage case is located ahead of the user in the user's forward direction relative to the user, and the electric luggage case is controlled to decelerate along the user's forward direction;

[0077] When the slider is in the first direction uniform speed zone or the second direction uniform speed zone, the electric suitcase is located behind the user in the user's forward direction relative to the user, and the electric suitcase is controlled to accelerate along the user's forward direction.

[0078] When the user is using the electric suitcase, the slider is first located in the first direction acceleration zone or the second direction acceleration zone, and the electric suitcase accelerates first; during the acceleration process, the slider will gradually approach the first direction uniform speed zone or the second direction uniform speed zone. When the slider enters the first direction uniform speed zone or the second direction uniform speed zone, the motor stops accelerating and maintains the current speed, so that the electric suitcase moves forward at a uniform speed; when the user's speed changes during walking, the slider will separate from the first direction uniform speed zone or the second direction uniform speed zone. If the user accelerates, the slider enters the first direction acceleration zone or the second direction acceleration zone, and the motor accelerates to keep up with the user's movement; if the user decelerates, the slider enters the first direction deceleration zone or the second direction deceleration zone, and the motor decelerates to avoid pulling the user forward. During the deceleration process, the slider will gradually approach the first direction uniform speed zone or the second direction uniform speed zone. When the slider enters the first direction uniform speed zone or the second direction uniform speed zone, the motor stops decelerating and maintains the current speed, so that the electric suitcase moves forward at a uniform speed.

[0079] Adjusting the acceleration of the electric suitcase based on the analysis result of the relative position between the user and the electric suitcase includes:

[0080] When the slider is in the first direction uniform speed zone or the second direction uniform speed zone, the acceleration of the electric luggage box is adjusted to 0;

[0081] When the slider is in any of the first direction acceleration zone, the second direction acceleration zone, the first direction deceleration zone, and the second direction deceleration zone, the acceleration curve in the corresponding area in the preset information is obtained, and the acceleration a is obtained on the acceleration curve corresponding to the slider position, and the electric suitcase is controlled to move at the acceleration a.

[0082] Among them, the curve of the acceleration curve near the first direction uniform speed zone or the second direction uniform speed zone is relatively gentle, and the acceleration gradually changes to 0, avoiding the feeling of sudden speed change due to the acceleration becoming 0 when the slider enters the first direction uniform speed zone or the second direction uniform speed zone, optimizing the user experience, reducing the wear on the motor, and extending the service life.

[0083] The forming of the stop acceleration condition based on the preset movement control information of the electric trunk and judging whether the movement of the electric trunk meets the demand according to the stop acceleration condition includes:

[0084] The stopping acceleration condition includes detecting that the position of the slider is located in the first direction uniform speed zone or the second direction uniform speed zone, and recording the current motor speed b, obtaining the moving speed v1 of the electric suitcase based on the motor speed b, and then adding the moving speed v1 of the electric suitcase and the slider stop position w to the speed curve in the preset information to form a new speed curve.

[0085] When the slider enters the first direction uniform speed zone or the second direction uniform speed zone, it means that the moving speed of the electric suitcase and the user are close to or equal, so the current motor speed is maintained to follow the user's movement at a uniform speed to give the user a better user experience; the newly recorded motor speed b is calculated to obtain the moving speed v1, and the speed curve is updated corresponding to the slider stop position w, so that the speed curve can better fit the user's usage habits and provide a better user experience.
