Description

Technical Field

[0001] The present invention relates to a handle of a luggage case, and particularly to a handle of a luggage case with a weighing component. Background Art

[0002] The Chinese invention patent application (patent application number: 201610427024.4, authorization announcement number: CN 105901889 B, name: luggage case handle with built-in weighing sensor) filed by the applicant with the State Intellectual Property Office on June 15, 2016 discloses a technical solution of a luggage case handle with a weighing sensor. In this solution, the weighing sensor is arranged on the lower surface of the middle part of the handle. Specifically, a concave cavity is provided in the middle of the bottom surface of the handle of the handle, and a long strip-shaped fixing seat made of a hard material is fixedly connected in the cavity. A weighing sensor is fixedly connected to the bottom surface of the fixing seat. The weighing sensor is fixed on the handle through the connection of its fixed end with the fixing seat. A rigid and closed lifting sleeve is fixedly connected to the loading end of the weighing sensor. The lifting sleeve surrounds the handle, the fixing seat and the weighing sensor, and its two ends are separated from the corresponding lifting components. At present, a large number of soft luggage cases and soft handles exist in the market and are developed and sold by manufacturers in large quantities.

[0003] Although the above solution has a better effect in terms of accurate weighing, it still has the following deficiencies:

[0004] 1. The lifting sleeve is arranged in the middle part of the handle. From the perspective of consumers, the appearance is not simple and the experience is not ideal.

[0005] 2. The structure is relatively complex, and the weighing sensor needs to be matched with a specially shaped fixing plate and lifting sleeve.

[0006] 3. The two force-bearing handle feet for connecting the luggage case on the handle are connecting blocks symmetrically arranged inside the left and right ends of the handle. The connecting block is fixedly connected to the handle, and its structure results in a longer length of the handle. If the length of the handle is reduced, the space for accommodating the palm becomes smaller.

[0007] 4. When the palm holds the lifting sleeve and lifts the luggage case upward, the position of the palm will have a certain influence on the weighing. That is, when the palm is in the central area of the lifting sleeve and in a position deviating from the central area, the weight of the luggage case measured by the weighing sensor is slightly deviated. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a weighing component and a luggage case handle for a luggage case handle with a shorter handle, higher weighing accuracy and better appearance experience.

[0009] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0010] The weighing component used on the handle of a luggage case of the present invention includes a weighing position frame with open upper and lower end faces, a load-bearing frame respectively installed in the weighing position frame, and a weighing sensor fixed to the bottom of the weighing position frame. The load-bearing frame is fixedly connected to the gravity loading end of the weighing sensor. It is characterized in that: the load-bearing frame is composed of a top frame plate and a bottom frame plate which are combined into a closed-loop structure through a male-female clamping structure and arranged up and down. On the inner lower surface of the top frame plate, there are downwardly extending force-bearing columns. Correspondingly, on the inner upper surface of the bottom frame plate, there are positioning holes for inserting the lower ends of the force-bearing columns. The bottom frame plate is composed of a lower connecting plate and a force-transmitting bow plate arranged on the upper surface of the outer side of the lower connecting plate and extending upward. Correspondingly, on the lower surface of the top frame plate, there are positioning screw holes for positioning the upper part of the force-transmitting bow plate thereon.

[0011] The force-transmitting bow plate is composed of an upper connecting plate and a relay plate. The outer end of the upper connecting plate is connected to the outer end of the lower connecting plate through the relay plate. A space is formed between the upper connecting plate and the lower connecting plate to accommodate a hanging ring member arranged at the end of the handle of the luggage case. The hanging ring member is sleeved on the force-bearing column and can reciprocate from the outside to the inside in the space.

[0012] At the position corresponding to the force-bearing column on the inner upper surface of the lower connecting plate, there is a convex platform extending upward. The top surface of the convex platform is an arc surface extending upward from the outside to the inside. The positioning hole is arranged in the center of the convex platform. Correspondingly, the surface shape of the peripheral area of the upper end of the force-bearing column on the top frame plate is also an arc surface extending in the same direction as the arc surface on the convex platform.

[0013] On the inner lower surface of the top frame plate, there is an upper surrounding wall with a closed inner structure and an open outer structure. The positioning screw hole is arranged in the area surrounded by the upper surrounding wall. The inner end of the upper connecting plate is embedded in the upper surrounding wall. The upper connecting plate is fixedly connected to the top frame plate by sequentially passing screws through the fixing holes arranged on the upper connecting plate and the positioning screw holes.

[0014] On the inner lower surface of the lower connecting plate, there is a lower surrounding wall with a closed inner structure and an open outer structure. The lower surrounding wall surrounds and penetrates the loading through hole of the lower connecting plate. The gravity loading end is embedded in the lower surrounding wall. The loading screw is sequentially passed through the force-bearing hole on the gravity loading end and the loading through hole and screwed into the loading screw hole arranged at the lower end of the force-bearing column.

[0015] The weighing sensor has a rectangular frame shape, and the strain gauge sensor is placed inside the rectangular frame. The fixed end on the strain gauge sensor is fixedly connected to the outer frame edge of the rectangular frame. The gravity loading end on the strain gauge sensor extends inward and is suspended inside the rectangular frame. This gravity loading end is fixedly connected to the inner lower surface of the lower connecting plate above it. The four corners of the rectangular frame are fixedly connected to the bottom frame of the weighing position frame by screws.

[0016] On the inner and outer sides outside the weighing position frame, there are respectively connecting and fixing columns that can fix the weighing position frame on the top plate of the luggage.

[0017] The luggage handle includes weighing components installed at both ends of the luggage handle, a display screen for displaying the weight of the luggage through the weighing components, and a control circuit board connected between the weighing sensor of the weighing components and the display screen. It is characterized in that: the weighing components are the weighing components of the present invention.

[0018] The force-bearing hanging parts connected to the weighing components at both ends of the luggage handle are hanging ring parts that are inclined from top to bottom and from inside to outside on the handle of the handle. There are long strip through holes extending from inside to outside on the hanging ring parts, and the long strip through holes are sleeved on the force-bearing columns on the weighing components.

[0019] The outer end of the hanging ring part extends outward beyond the handle.

[0020] Compared with the prior art, the luggage handle of the present invention has the following advantages: 1. Since the hanging ring parts are inclined and stored inside the weighing position frame when the luggage is not lifted, the length of the luggage handle can be made shorter; 2. When the luggage is lifted upward, the force-bearing columns apply an upward pulling force to the gravity loading end of the weighing sensor. Since the top frame plate and the bottom frame plate form a stable and reliable closed-loop structure, the outer end of the lower connecting plate of the bottom frame plate is pressed against the fixed end of the gravity sensor by the force-bearing columns under the force in the obliquely upward direction, causing the strain gauge sensor of the weighing sensor to deform and output a signal; 3. By using the back seat plate fixedly connected to the top surface of the luggage and the weighing position frame embedded in the back seat plate, the appearance of the luggage is simple and neat, enhancing the user experience.

Detailed implementation manners

[0032] As Figures 1 - 9 shown, the weighing component used on the handle 1 of the present invention is hidden and installed on the top plate of the luggage. The top plate of the luggage is preferably the back plate seat 11 which is installed and fixedly connected to the top of the luggage and has an integral structure. The back plate seat 11 is provided with a plurality of installation positions for accommodating different components. When the user lifts the luggage (including a suitcase, a travel case and a handbag with a hard top plate), the weighing component can display the weight of the luggage sensed and measured by it on the display screen 61 provided near the handle 1 of the luggage.

[0033] I. Weighing component

[0034] As Figure 2 shown, the weighing component includes a weighing position frame 2, a load-bearing frame 3, a load cell 7, a control circuit board 63, a display screen 61, and a battery 64.

[0035] 1. Weighing position frame 2

[0036] As shown Figure 1 , Figure 2 , Figure 9 , there are two, respectively arranged on both sides of the handle 1. Preferably, they are injection molded parts. Their outer contour is a rectangular frame body, and their top and bottom end faces are open (see Figure 3 , Figure 6 , Figure 8 ). There is an annular edge around the top end face of the weighing frame 2, and this annular edge is used to snap and install the weighing frame 2 on the backplane seat 11. The left and right side faces of the weighing frame 2 are closed surfaces, and its front and rear side faces are preferably open, which is convenient for observing when installing the load-bearing frame 3 inside. Connecting and fixing columns 21 are provided on the outer sides of the left and right side walls (the outer here refers to outside the frame body of the weighing frame 2), and screw holes are provided on the bottom end faces of the connecting and fixing columns 21. When the weighing frame 2 is installed in the corresponding installation position on the backplane seat 11 in an embedded manner, screws are passed upward through the backplane seat 11 from below the backplane seat 11 and screwed into the screw holes, thereby fixing the weighing frame 2 on the luggage.

[0037] 2. Plate position frame 6

[0038] As shown Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8 , Figure 9 , there is one, preferably an injection molded part. Bounded by the weighing frame 2, it is arranged on the side of the weighing frame 2 away from the center of the handle 1. Its outer contour is also a rectangular frame body. The plate position frame 6 and the weighing frame 2 can be an integral structure or a separated structure. The display screen 61, control circuit board 63, battery 64 and battery compartment 65 are all installed in the plate position frame 6. A face sticker 62 for preventing water vapor and dust from contaminating the surface of the display screen 61 is provided on the top surface of the display screen 61. Similarly, the plate position frame 6 is fixedly installed in the installation position designed for the plate position frame 6 on the backplane seat 11 in an embedded manner.

[0039] 3. Load-bearing frame 3

[0040] As shown Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , the load-bearing frame 3 can be made of metal materials such as stainless steel and alloy steel, and is preferably made of hard plastic materials. It is installed inside the frame body of the weighing frame 2.

[0041] It is composed of a top frame plate 4 and a bottom frame plate 5 arranged below the top frame plate 4. The top frame plate 4 and the bottom frame plate 5 are combined up and down through a male-female snap-fit structure to form a closed-loop structure.

[0042] 1) Top frame plate 4

[0043] An integral structure, which is composed of a top flat plate 41, a downward convex platform 42 extending downward from the bottom surface of the top flat plate 41, and a stress column 46 provided on the inner lower surface of the downward convex platform 42 (inside the frame of the weighing position frame 2, the direction pointing to the center of the handle 1 is the inner side, and the direction away from the center of the handle 1 is the outer side, the same below) and continuing to extend downward. A loading screw hole 75 is provided on the lower end surface of the stress column 46. The length of the stress column 46 is determined by the size of the handle 1 selected according to the size of the luggage used. In the present invention, its length range is preferably 20 mm - 40 mm, and the single value is preferably 26 mm and 29 mm.

[0044] An upper surrounding wall 43 with a closed inner structure and an open outer structure is provided beside the outer side of the downward convex platform 42, and a positioning screw hole 44 is provided in the area enclosed by the upper surrounding wall 43.

[0045] The surface shape of the peripheral area of the downward convex platform 42 where the stress column 46 is located is an arc surface 45 extending upward from the outer side to the inner side.

[0046] 2) Bottom frame plate 5

[0047] An integral structure, which is composed of a lower connecting plate 51 and a force - transmitting bow - shaped plate 52 provided on the outer upper surface of the lower connecting plate 51 and extending upward. Correspondingly, a positioning screw hole 44 for positioning the upper part of the force - transmitting bow - shaped plate 52 is provided on the lower surface of the top frame plate 4.

[0048] The force - transmitting bow - shaped plate 52 is composed of an upper connecting plate 521 and a relay plate 522. The outer end of the upper connecting plate 521 is connected to the outer end of the lower connecting plate 51 through the relay plate 522. A space for accommodating a hanging ring member 13 provided at the end of the luggage handle 1 is formed between the upper connecting plate 521 and the lower connecting plate 51. The hanging ring member 13 is provided with a long strip through - hole 14, which is sleeved on the stress column 46 and can reciprocate from the outer side to the inner side in the space.

[0049] An upward convex platform 511 extending upward is provided at the position corresponding to the upper and lower positions of the stress column 46 on the inner upper surface of the lower connecting plate 51. The top surface shape of the upward convex platform 511 is an arc surface 45 extending in the same direction as the arc surface 45 on the downward convex platform 42. A positioning hole 512 sunken downward is provided at the center of the upward convex platform 511. A loading through - hole penetrating the lower connecting plate 51 is provided at the bottom of the hole. The diameter of the loading through - hole is smaller than the inner diameter of the positioning hole 512. The lower end of the stress column 46 is inserted into the positioning hole 512.

[0050] A fixing hole 523 is provided at the inner end of the upper connecting plate 521. The inner end of the upper connecting plate 521 is embedded in the upper surrounding wall 43 of the top frame plate 4. The upper surrounding wall 43 restricts the inner end of the upper connecting plate 521 from shifting forward, backward, and inward in the horizontal plane (taking Figure 1 the paper surface direction as an example, the direction pointing to the observer is forward, and the direction away from the observer is backward, the same below). The upper connecting plate 521 can be fixedly connected to the top frame plate 4 by sequentially passing screws through the fixing hole 523 and the positioning screw hole 44.

[0051] The above structure can combine the top frame plate 4 and the bottom frame plate 5 into a stable and reliable closed-loop structure. In addition, the channel formed by the two arc surfaces 45 extending upward on the downward convex platform 42 and the upward convex platform 511 enables the hanging ring member 13 to be made into an arc-shaped member. When lifting the luggage, the pulling-out trajectory of the hanging ring member 13 is arc-shaped. When putting down the luggage, the hanging ring member 13 can be hidden in the space enclosed by the top frame plate 4 and the bottom frame plate 5.

[0052] On the inner lower surface of the lower connecting plate 51, a lower surrounding wall 513 with a closed inner structure and an open outer structure is provided. The lower surrounding wall 513 surrounds the loading through hole.

[0053] 4. Weighing sensor 7

[0054] As Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 shown, the outer shape of the weighing sensor 7 is a rectangular frame 71. The rectangular frame 71 is made of steel material. On the outer frame edge of the rectangular frame 71, a suspended plate 72 extending into the rectangular frame 71 and integrated with the rectangular frame 71 is provided. At the four corners of the rectangular frame 71, screw holes 75 are provided. At the inner end of the suspended plate 72, a force-receiving hole 74 is provided. One half-bridge strain gauge sensor 73 of the weighing sensor 7 is mounted on the lower surface of the suspended plate 72 (the other half-bridge strain gauge sensor 73 of the weighing sensor 7 is installed on the bottom frame arranged in another weighing position frame 2).

[0055] The fixed end of the strain gauge sensor 73 (preferably a resistive strain gauge) of the weighing sensor 7 is placed on the outer side of the suspended plate 72, and the gravity loading end of the strain gauge sensor 73 is placed on the inner side of the suspended plate 72. The inner end of the suspended plate 72 is embedded in the lower surrounding wall 513. The lower surrounding wall 513 restricts the suspended plate 72 from shifting forward, backward, and inward in the horizontal plane.

[0056] The rectangular frame 71 is fixedly connected to the bottom frame of the weighing frame 2 by screws passing through the screw holes 75 at the four corners of the rectangular frame 71; the inner end of the suspended plate 72 is fixed to the bottom frame plate 5 by screws sequentially passing through the force holes 74 and the loading through holes and screwed into the loading screw holes 75, so that the gravity loading end is fixed together with the force receiving column 46.

[0057] Two half-bridge strain gauge sensors 73 are grouped by wires according to a Wheatstone bridge (also known as a Wheatstone bridge) and electrically connected to the control circuit board 63.

[0058] In the above structure, the contact point between the gravity loading end and the force receiving column 46 can be made smaller. A smaller contact point can reduce the weighing error caused by the deviation of the force application direction when lifting the luggage by hand, resulting in the offset of the force receiving point of the strain gauge sensor 73. Therefore, the present invention adopts a smaller contact point, which can greatly improve the weighing accuracy.

[0059] II. Luggage handle 1

[0060] As Figure 1 、 Figure 2 、 Figure 9 shown, it includes a handle 12 held by hand when lifting the luggage, force receiving hanging parts and a weighing assembly arranged at both ends of the handle 12 and connected to the weighing frame 2. The weighing assembly is the weighing assembly described above in the present invention.

[0061] The handle 12 can be made of plastic material. The present invention preferably uses a soft plastic material. The force receiving hanging part is the hanging ring part 13, which is an integral structure with the handle 12. The upper end of the hanging ring part 13 is placed inside the handle 12, and its shape is designed to be inclined from top to bottom and from inside to outside. The outer end of the hanging ring part 13 extends outside the handle 12. This structure can make the length of the handle 12 shorter. When the luggage is not lifted, the force receiving hanging ring part 13 is hidden and stored in the space between the top frame plate 4 and the bottom frame plate 5 inside the weighing frame 2. At this time, the distance between the handle 12 and the top surface of the luggage is also shorter. Therefore, the handle 12 of the present invention can be made smaller and can also have an almost straight-line outer shape.

[0062] The hanging ring part 13 is provided with a long strip through hole 14 extending from inside to outside, and the long strip through hole 14 is sleeved on the force receiving column 46 on the weighing assembly.

[0063] III. Force analysis when lifting the luggage upward

[0064] 1. Since the force receiving column 46 is fixedly connected to the gravity loading end, when the luggage is lifted upward, the hanging ring part 13 pulls up the force receiving column 46, causing the gravity loading end to shift upward. At this time, the strain gauge sensor 73 deforms and outputs a weighing signal.

[0065] 2. Since the top frame plate 4 and the bottom frame plate 5 form a stable and reliable closed-loop structure, when the luggage is lifted upward, the hanging ring member 13 pulls the force-bearing column 46 upward and causes an external force acting upward on the gravity loading end. When the force-bearing column 46 is pulled obliquely upward, it drives the outer end of the lower connecting plate 51 to press against the outer end of the suspended plate 72, that is, against the fixed end of the strain gauge sensor 73. In this way, the strain gauge sensor 73 deforms and outputs an electrical signal with a changed resistance value.
