Description

Technical Field

[0001] The utility model relates to the technical field of weighing instrument accessories, in particular to a camera linkage flipping structure and a weighing device with the flipping structure. Background Art

[0002] Traditional AI scales are electronic scales combined with artificial intelligence technology, which are widely used in commercial environments, such as supermarkets or fresh food markets, to achieve rapid and accurate identification and weighing of goods. Such scales are usually equipped with cameras and advanced software algorithms, and can identify various fruits, vegetables and other goods placed on them.

[0003] However, there are some deficiencies in the design of existing electronic scales, especially regarding the stability of the vertical rod: Most electronic scales on the market currently have a vertical rod structure for installing devices such as cameras. The folding stability of the vertical rod mainly depends on the torque of the rotating shaft itself to maintain, but the damping effect provided by this torque is limited, and it is prone to tipping when subjected to external forces, thus increasing the risk of damage to important components such as cameras.

[0004] In order to improve this situation, the applicant previously proposed a weighing device that is easy to use (Chinese Patent Publication No. CN116818076A). This device effectively prevents the problem of its forward tipping when the vertical rod is in a vertical state by adding a first limiting component.

[0005] Although the above solution solves the problems of the stability of the vertical rod and the convenience of use to a certain extent, the new problems derived therefrom cannot be ignored: Specifically, after the vertical rod is manually erected, the camera module needs to be manually rotated to adjust to the best irradiation position at the center of the weighing pan. Since manual adjustment often has certain errors, it is difficult to ensure that the camera is accurately aligned with the center of the weighing pan, which is likely to affect the accuracy of AI recognition.

[0006] In view of this, the inventor specifically designed a camera linkage flipping structure and a weighing device with the flipping structure, and this case was thus generated. Summary of the Utility Model

DETAILED DESCRIPTION

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] The utility model specifically implements a camera linkage flipping structure and a weighing device with the flipping structure. The camera linkage flipping structure and the weighing device will be described respectively through two specific implementation methods below.

[0048] Embodiment 1

[0049] See also Figures 1 to 11 , is a camera linkage flip structure as the best embodiment of the utility model, comprising:

[0050] The vertical rod 10 is columnar, and the bottom of the vertical rod 10 is pivotally connected to the scale body 70 through a damping rotation structure so that the top of the vertical rod 10 forms a free end that can be flipped relative to the scale body 70;

[0051] The linkage mechanism 20 is disposed in the vertical rod 10 and has an extended state and a retracted state as the vertical rod 10 turns over;

[0052] The trigger structure 30 is in transmission connection with the linkage mechanism 20, and is used to switch the linkage mechanism 20 between the extended state and the retracted state as the upright 10 turns over;

[0053] The flip member 40, the middle of which is rotatably connected to the free end of the top of the upright pole 10 so that the top and bottom of the flip member 40 respectively form an upper swing end and a lower swing end (not shown in the figure) that can rotate and swing around the middle of the flip member 40;

[0054] The camera assembly 50 has a bottom portion rotatably connected to the upper swing end of the top of the flip member 40 via a connecting member 51;

[0055] The contact structure 60 is provided at the free end of the top of the vertical pole 10, and is used to movably contact the connecting member 51 with the swing of the camera assembly 50 so that the connecting member 51 drives the camera to swing at a fixed angle around the rotation axis between the camera assembly 50 and the upper swing end;

[0056] Among them, the lower swinging end of the flipping member 40 drives the connecting linkage mechanism 20 to rotate with the flipping of the vertical pole 10 so that the connecting member 51 drives the camera assembly 50 to swing in the direction close to or away from the contact structure 60. When the vertical pole 10 is flipped up relative to the scale body 70, the linkage mechanism 20 is in an extended state.

[0057] Specifically, Figure 2 , 3 As shown in , 4, the vertical rod 10 as a whole is a shell with a hollow interior, and the inner side of the shell forms a mounting cavity 11, the linkage mechanism 20 includes a connecting seat 21, an upper connecting rod 22 and a lower connecting rod 23, the middle part of the connecting seat 21 is rotatably connected to the inner wall of the mounting cavity 11 so that its two ends form a first swing end 211 and a second swing end 212 that can rotate and swing up and down around its rotation axis, the lower end of the upper connecting rod 22 is rotatably connected to the first swing end 211, and the upper end of the lower connecting rod 23 is rotatably connected to the second swing end 212.

[0058] Specifically, the cross-section of the connecting seat 21 is spindle-shaped, and hinge slots 213 are symmetrically formed at both ends thereof. The lower end of the upper connecting rod 22 and the upper end of the lower connecting rod 23 are pivotally connected to the two hinge slots 213 through a fourth hinge shaft (not shown in the figure). The middle of the connecting seat 21 is pivotally connected between two opposite side walls of the installation cavity 11 through a fifth hinge shaft 214. In this embodiment, the fifth hinge shaft 214 is pivotally connected between the inner side walls of the two installation cavities 11 parallel to the rotation axis of the vertical rod 10. Thus, when the lower end of the lower connecting rod 23 cooperates with the triggering structure 30 to move up and down, the second swing end 212 of the connecting seat 21 hinged to the lower connecting rod 23 rotates up and down around the fifth hinge shaft 214 following the up and down movement of the lower connecting rod 23. Furthermore, the first swing end 211 at the other end of the connecting seat 21 drives the upper connecting rod 22 to achieve an up and down movement state opposite to that of the lower connecting rod 23, that is, to switch between the extended state and the retracted state. The extended state corresponds to the downward movement of the lower connecting rod 23, driving the upper connecting rod 22 to move upward relatively to achieve the extended state, and the retracted state corresponds to the upward movement of the lower connecting rod 23, driving the upper connecting rod 22 to move downward to achieve the retracted state.

[0059] Further, as Figure 3 shown, in order to facilitate the installation of the camera assembly 50 and the convenient connection with the linkage mechanism 20, an installation groove 12 is formed by recessing downward at the upper end of the vertical rod 10. In this embodiment, the cross-section of the installation groove 12 is L-shaped, that is, it is only open on one side facing the top of the vertical rod 10. The top end of the vertical rod 10 is semi-cylindrical, and the installation groove 12 is open in one of the horizontal directions facing the top of the vertical rod 10. This opening direction enables the installation groove 12 to face the weighing instrument main body 70 when the vertical rod 10 is folded on the weighing instrument main body 70. Thus, the opening of the installation groove 12 facing the opening direction enables the camera assembly 50 to rotate and fold in the direction of its opening.

[0060] Specifically, as Figure 3 、 7As shown, a connecting hole 13 which is connected to the installing cavity 11 is provided at the bottom of the installing groove 12, and a hinge seat 14 is provided at the bottom of the installing groove 12 and located at the position of the connecting hole 13. The middle part of the flip member 40 is hingedly connected to the hinge seat 14, and the upper end of the upper connecting rod 22 is rotatably connected to the connecting piece 24, and the other end of the connecting piece 24 is rotatably connected to the lower swinging end of the flip member 40. Therefore, when the upper connecting rod 22 extends upward along with the flipping of the main body of the vertical rod 10, the top end of the upper connecting rod 22 moves toward the connecting hole 13, and through the connecting rod action of the connecting piece 24, the lower swinging end of the flip member 40 is pushed toward one side of its rotation axis, so that the upper swinging end of the flip member 40 is flipped relative to the rotation axis of the flip member 40 and deflected to the other side opposite to the lower swinging end, thereby realizing the upper swinging The first flipping of the camera assembly 50 connected to the moving end, and in this embodiment, the lower end of the connecting piece 24 is arranged on the side deviating from the center of the upper connecting rod 22, and when the connecting piece 24 is pushed up to the highest position with the upper connecting rod 22, the lower swing end of the flip member 40 is flipped 90° around its rotation axis relative to its initial position to provide an initial upward angle, so that the lower swing end of the flip member 40 can always flip and swing to one side, and the swinging side is set to swing toward the side wall of the mounting groove 12, so that the camera assembly 50 can swing toward the opening side of the mounting groove 12, thereby providing a space concession basis and an action connection basis for the first rotation of the camera assembly 50, facilitating the first 90° rotation of the camera assembly 50.

[0061] Preferably, Figure 4 , 6 As shown, a rotating shaft 15 is provided at the bottom of the vertical rod 10, and a connecting shaft 16 is vertically fixed at one end of the rotating shaft 15. The trigger structure 30 includes a trigger turntable 31 rotatably provided on the scale body 70 and located below the rotation connection position of the vertical rod 10, a first linkage rod 32 and a second linkage rod 33. The first linkage rod 32 and the second linkage rod 33 are both L-shaped, the upper end of the first linkage rod 32 is hinged to the lower end of the lower connecting rod 23, and the upper end of the second linkage rod 33 is hinged to the lower end of the connecting shaft 16. The other ends of the first linkage rod 32 and the second linkage rod 33 are both movably hinged to the circumferential edge of the trigger turntable 31 and are located in a close position so that when the trigger turntable 31 rotates, the upper ends of the first linkage rod 32 and the second linkage rod 33 move upward or downward synchronously.

[0062] Specifically, in this embodiment, the trigger turntable 31 is fixed to the inner side of the scale body 70 through a turntable seat 34 and is located below the rotation connection position between the vertical rod 10 and the scale body 70. The first linkage rod 32 and the second linkage rod 33 are both L-shaped rods, and their bent parts are located at the lower ends. The upper ends of the first linkage rod 32 and the second linkage rod 33 are respectively hinged to the lower end of the lower connecting rod 23 and the end of the shaft member 15 through a rotating shaft, wherein the end of the shaft member 15 can rotate with the rotation of the vertical rod 10, so that the connecting shaft 16 swings around its rotation axis following the rotation of the vertical rod 10. The lower ends of the first linkage rod 32 and the second linkage rod 33, that is, the bent parts of the two The ends of the first linkage rod 32 and the second linkage rod 33 are directly inserted into the end surface of the trigger turntable 31 and are located at a position close to the trigger turntable 31. Therefore, when the trigger turntable 31 rotates, the lower ends of the first linkage rod 32 and the second linkage rod 33 can achieve the same upward and downward movement directions, thereby driving the lower connecting rod 23 at the upper end to achieve synchronous upward or downward movement with the end of the connecting shaft 16. The hinge direction of the first linkage rod 32 and the second linkage rod 33 and the lower connecting rod 23 and the connecting shaft 16 is the same as the rotation direction of the vertical rod 10, and the direction in which the bent parts of the lower ends of the first linkage rod 32 and the second linkage rod 33 are inserted into the trigger turntable 31 is also the same as the rotation direction of the vertical rod 10. The purpose of the above design is that Figure 9 As shown, when the vertical pole 10 is in the initial state, that is, the state that it is not flipped up, the rotating shaft member 15 drives the connecting shaft 16 to swing to a horizontal state away from the camera assembly 50. At this time, under the pull of the lower end of the connecting shaft 16, the trigger turntable 31 rotates upward, thereby driving the lower end of the first linkage rod 32 to rotate upward synchronously, and then the upper end of the first linkage rod 32 pushes up the bottom of the lower connecting rod 23, and the bottom of the lower connecting rod 23 drives the upper connecting rod 22 to move downward around the connecting seat 21, and the upper end of the upper connecting rod 22 straightens the camera assembly 50 by pulling down the flip member 40, thereby restoring the initial parallel state of the camera assembly 50 and the vertical pole 10; Figure 10 As shown, when the vertical pole 10 is flipped up, the rotating shaft 15 drives the connecting shaft 16 to swing to a vertical state away from the camera assembly 50, and the second linkage rod 33 moves downward following the downward swing of the connecting shaft 16, so that its lower end drives the trigger turntable 31 to rotate downward, and simultaneously drives the first linkage rod 32 to move downward, thereby causing the lower connecting rod 23 to move downward, and the upper connecting rod 22 moves upward around the connecting seat 21 relative to the lower connecting rod 23, lifting the flipping member 40 to make it in a horizontal state, thereby driving the camera assembly 50 to flip to the first horizontal state, and subsequently through the contact structure 60 with the camera assembly 50, it is fixed to swing at a certain angle, thereby realizing automatic and fixed-angle flipping of the camera assembly 50.

[0063] Thus, by triggering the cooperation between the rotary disk 31 and the vertical rod 10 to rotate, the linkage mechanism 20 can be transformed between the extended state and the retracted state as the vertical rod 10 flips, automatically realizing the flipping of the camera assembly 50 without manual intervention and adjustment.

[0064] Preferably, as Figure 7 , 8 , as shown in FIGS. 11, the flipping member 40 includes a flipping main body 41 in the shape of a square column and a rotating shaft end 42 in the shape of a cylinder provided at one axial end of the flipping main body 41. The connecting member 51 includes a sleeve portion 511 in the shape of a cylinder and a connecting portion 512 provided at the upper end of the sleeve portion 511. A sleeve hole 513 that can be rotatably sleeved with the rotating shaft end 42 is formed at the lower end of the sleeve portion 511, and the connecting portion 512 is detachably fixed to the lower end of the camera assembly 50.

[0065] Specifically, an arc-shaped deflection groove 514 distributed circumferentially around it is provided on the circumferential side of the sleeve portion 511 and in the direction close to the contact structure 60. The contact structure 60 is a contact shaft in the shape of a rod and erected on the mounting groove 12. The contact shaft is provided on the rotational swing path of the arc-shaped deflection groove 514 so that when the vertical rod 10 flips, the contact shaft penetrates into the arc-shaped deflection groove 514, thereby realizing a fixed deflection angle of the camera assembly 50 around the rotating shaft end 42.

[0066] Furthermore, two contact surfaces 515 distributed radially along the sleeve portion 511 are formed on both sides of the arc-shaped deflection groove 514. The contact shaft includes a columnar base portion 61 and a contact portion 62 protruding coaxially from the center of the upper end of the base portion 61.

[0067] In this embodiment, the base portion 61 and the contact portion 62 are arranged on the opening side of the mounting groove 12 and biased towards one side of the center position of the weighing instrument main body 70 for weighing. When the vertical rod 10 is turned up, the sleeve portion 511 drives the camera assembly 50 to achieve the first 90° flip. During the flipping process, the sleeve portion 511 flips with the flipping member 40 until the contact portion 62 is inserted into the arc-shaped deflection groove 514. The contact surface 515 on the side of the arc-shaped deflection groove 514 close to the weighing center position of the weighing instrument main body 70 first contacts the contact portion 62. As the sleeve portion 511 continues to swing downward, the contact portion 62 restricts the movement trajectory of the arc-shaped contact portion 62, causing the sleeve portion 511 to deflect around the rotating shaft end 42 towards the weighing center position of the weighing instrument main body 70, realizing the second flip of the camera assembly 50.

[0068] In this embodiment, the base portion 61, the contact portion 62, and the arc-shaped deflection groove 514 on the sleeve portion 511 are arranged such that when the camera assembly 50 reaches the position of the first 90° flip, they simultaneously deflect 30° towards the direction of the weighing center position of the weighing instrument main body 70, so that the camera module of the camera assembly 50 is exactly aligned with the weighing center position of the weighing instrument main body 70, realizing a more accurate automatic alignment.

[0069] In addition, as an adjustable part, the second yaw angle of the camera assembly 50 can be adaptively adjusted according to the weighing center position of the weighing instrument main body 70. The positions, orientations, etc. of the arc-shaped deflection grooves 514 on the adjustment base 61, the contact part 62, and the bushing part 511 are adjusted so that the camera assembly 50 finally aligns with the weighing center position, which is not limited herein.

[0070] Preferably, as Figure 7 shown, there are two hinge seats 14, which are symmetrically distributed on both sides of the communication hole 13. First hinge holes 141 are opened at the upper ends of the two hinge seats 14 and are located on the same straight line. A rotation hole 43 in the same direction as the first hinge holes 141 is formed through the middle of the flipping member 40. The rotation hole 43 is pivotally connected to the two first hinge holes 141 through a first hinge shaft 44.

[0071] Furthermore, a second hinge hole 45 parallel to the connecting line direction of the two first hinge holes 141 is formed through the lower end of the flipping main body 41. A third hinge hole 221 parallel to the second hinge hole 45 is formed through the upper end of the upper connecting rod 22. There are two connecting pieces 24, which are parallelly distributed on both sides of the second hinge hole 45 and the third hinge hole 221. The upper and lower ends of the two connecting pieces 24 are pivotally connected to the flipping main body 41 and the upper connecting rod 22 respectively through a second hinge shaft and a third hinge shaft (not shown in the figure).

[0072] Thus, through the above-mentioned first hinge holes 141, rotation holes 43, first hinge shafts 44, second hinge holes 45, third hinge holes 221, second hinge shafts, and third hinge shafts, the pivotal connection between the upper connecting rod 22, the flipping member 40, and the connecting pieces 24 can be conveniently realized, so that the flipping member 40 can adaptively flip and yaw following the extension state and retraction state changes of the linkage mechanism 20, which is convenient for realizing the stable rotation process of the camera assembly 50.

[0073] Embodiment 2

[0074] As Figure 12 shown, a weighing device with a camera linkage flipping structure includes a weighing instrument main body 70 and a camera linkage flipping structure rotatably connected to the bottom of the weighing instrument main body 70.

[0075] Specifically, in this embodiment, a weighing pan 71 is provided on the upper end surface of the weighing instrument main body 70, and a rectangular area 72 adapted to the vertical rod 10 is reserved for installing the vertical rod 10. The lower end of the vertical rod 10 is rotatably connected to one end of the rectangular area 72 in the length direction through a damping member. Thus, when the vertical rod 10 is completely folded and flipped, it can just be hidden in the rectangular area 72. The trigger turntable 31 and the turntable seat 34 are arranged below the rectangular area 72 of the weighing instrument main body 70 and below the hinge position of the vertical rod 10.

[0076] Combination Figure 2 , 3 In order to achieve smooth linkage between the first linkage rod 32, the second linkage rod 33 and the trigger turntable 31, a corresponding slot 73 can be used to make room on the end surface of the scale body 70, and an arc-shaped making room 17 is opened at the lower end of the vertical rod 10 and on the side close to the holding area.

[0077] The beneficial effects of the utility model are as follows:

[0078] The utility model realizes the flipping control of the flipping member 40 through the linkage mechanism 20 and the trigger structure 30 inside the vertical pole 10, thereby realizing the flipping linkage of the camera assembly 50. When the vertical pole 10 is manually lifted, the camera module can automatically rotate to the preset optimal irradiation position without additional manual adjustment, ensuring that the camera can be accurately aligned with the center of the scale pan each time it is used.

[0079] The camera module in the present invention realizes two rotations through the linkage structure. First, it follows the flip member 40 to realize a 90-degree flip relative to the vertical pole 10. Then, under the action of the contact structure 60, the camera assembly 50 rotates about 30 degrees around the upper swing end of the upper end of the flip member 40 toward the scale plate. This ensures that the camera can identify the goods at a specific and consistent angle. In addition, it can eliminate the step of manually adjusting the camera angle each time it is used, avoids the angle deviation caused by manual adjustment, reduces the operation time, and improves the work efficiency during the weighing process.

[0080] In summary, the utility model enables the camera module to automatically rotate to the optimal position through the linkage flip structure, which not only improves the consistency and accuracy of AI electronic scale recognition, but also simplifies the operation process and greatly improves the working efficiency of the weighing device.

[0081] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
