[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application 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 application and are not used to limit the present application.

[0029] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0030] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0031] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0032] In the related art, in applications where the bin body and the cover body are opened by rotating, the bin body and the cover body are usually connected in a freely rotating manner, so that the rotation of the cover body is not restricted. Therefore, when the cover body is opened, the cover body is closed with the bin body due to its own gravity, which affects the use. For example, when applied to a handheld printer, the automatic closing of the cover body will cause the paper to deform, and cause problems such as pinching the hands and affecting the paper placement during operation. In order to solve the above technical problems, the utility model provides a cover opening detection device.

[0033] In order to solve the above problems, this application discloses the following technical solutions.

[0034] A device for preventing a cover from automatically resetting after opening, comprising a cover, a bin and a rotating body; the first end of the rotating body is connected to the cover; the second end of the rotating body is rotatably connected to the bin; the rotating body is used to drive the cover to open and close relative to the bin; a limiting portion is provided at the second end of the rotating body; a limiting member is provided on the bin in the direction in which the rotating body rotates when opening the cover, and the limiting member is used to engage with the limiting portion when the cover is opened.

[0035] From the above description, it can be seen that the beneficial effect of the utility model is that a rotatable connection is formed between the cover body and the warehouse body through the rotating body, and a limit part is set at the second end of the rotating body, and a limit piece cooperating with the limit part is set on the warehouse body, so that after the cover body is rotated by the rotating member to complete the opening action, the limit piece and the limit part on the rotating body form a snap fit, so that the cover body cannot release the snap fit between the limit piece and the limit part when it is only subjected to its own gravity, thereby avoiding automatic resetting of the cover body during the opening process, and it is easy to use.

[0036] In one embodiment of the present application, the contact surface between the limiting member and the limiting portion is a curved surface.

[0037] It can be seen from the above description that by making the contact surface between the limiting member and the limiting portion an arc surface, the clamping fit between the limiting member and the limiting portion can be released only when further external force is applied to the cover body.

[0038] In one embodiment of the present application, the warehouse body is provided with an avoidance groove, which corresponds to the position of the second end of the rotating body; the depth of the avoidance groove is greater than the height of the limiting part, so that the limiting part can rotate in the avoidance groove.

[0039] It can be seen from the above description that by providing an avoidance groove on the bin body, the limiting part can rotate in the avoidance groove, thereby avoiding the problem that the limiting part and the bin body cannot rotate smoothly due to the protrusion of the limiting part.

[0040] In one embodiment of the present application, the limiting member is disposed at a first end of the avoidance groove; the first end of the avoidance groove is close to an opening end of the cover body.

[0041] It can be seen from the above description that by arranging the limiting member at the first end of the avoidance groove, the limiting portion can be effectively engaged with the limiting member after being separated from the avoidance groove.

[0042] In one embodiment of the present application, a side of the limiting member close to the avoidance groove is an arc-shaped surface.

[0043] From the above description, it can be seen that by setting the side of the limiting member close to the avoidance groove as an arc surface, the limiting part can be more easily rotated through the front end of the limiting part, thereby forming a snap fit with the rear end or top of the limiting part.

[0044] In one embodiment of the present application, a side of the limiting member close to the avoidance groove is an arc-shaped surface.

[0045] From the above description, it can be seen that by making the side of the limit member away from the avoidance groove into a plane, when the limit part passes over the front end of the limit part, it can form an effective snap-fit ​​with the rear end or top end of the limit part, thereby preventing the cover body from releasing the snap-fit ​​between the limit part and the limit member due to its own weight.

[0046] In one embodiment of the present application, the bottom surface of the avoidance groove is an arc surface, and its curvature is adapted to the curvature of the first end of the rotating body.

[0047] It can be seen from the above description that by setting the avoidance groove as an arc groove that matches the curvature of the first end of the rotating body, the limit portion is prevented from contacting the avoidance groove during the rotation process, making the rotation process more stable.

[0048] In one embodiment of the present application, the first end of the rotating body is circular, a rotating axis is disposed at the center of the circle, and the limiting portion is disposed on the circumference of the circle.

[0049] From the above description, it can be seen that by setting the first end of the rotating body to a circle and setting the limiting part on the circumferential side of the circle, the limiting part rotates simultaneously when the first end rotates, so that when the limiting part rotates to the position where the limiting member is located, a snap-fit ​​is achieved.

[0050] In one embodiment of the present application, the warehouse body is provided with a rotating frame; the rotating shaft is mounted on the rotating frame.

[0051] From the above description, it can be seen that by arranging a rotating frame on the warehouse body and a rotating shaft on the rotating body, the rotational connection between the rotating body and the warehouse body is realized by arranging the rotating shaft on the rotating frame; at the same time, since the rotating frame is semi-open, the rotating shaft has a certain displacement margin, so that when the limiting part rotates to a position cooperating with the limiting member, the rotating shaft can be slightly displaced, thereby realizing the snap-fitting of the limiting part with the limiting member.

[0052] In one embodiment of the present application, a fixing buckle is provided at the first end of the rotating body; a fixing hole is provided on the cover body, and the first end of the rotating body is connected to the cover body through the cooperation of the fixing buckle and the fixing hole.

[0053] It can be seen from the above description that the detachable connection between the rotating body and the cover body is achieved through the fixing buckle and the fixing hole, so that when the limiting part of the rotating body is worn, it can be easily replaced.

[0054] Another embodiment of the utility model provides an electronic device, including the above-mentioned device for preventing the cover from automatically resetting after opening. The electronic device may include PDA (Personal Digital Assistant), handheld electronic device, POS device, handheld payment terminal and other devices. For example, when the electronic device is a POS machine, the POS machine includes an operating terminal and an upper cover rotatably connected to the operating terminal; wherein the upper cover serves as a cover body and the operating terminal serves as a compartment body, and the two are rotatably connected through a rotating body.

[0055] The device and electronic device for preventing the cover from automatically resetting after opening the cover provided by the utility model can be applied to the scene of a handheld printer, and are described below through specific implementation methods:

[0056] Embodiment 1

[0057] Please refer to Figure 1 , a device to prevent the cover 1 from automatically resetting after opening, comprising the cover 1, the bin 2 and the rotating body 3; the first end of the rotating body 3 is connected to the cover 1; the second end of the rotating body 3 is rotatably connected to the bin 2; the rotating body 3 is used to drive the cover 1 to open and close the cover relative to the bin 2; the second end of the rotating body 3 is provided with a limiting portion 31; the bin 2 is provided with a limiting member 21 in the direction of rotation of the rotating body 3 along the opening of the cover, and the limiting member 21 is used to engage with the limiting portion 31 when the cover 1 is opened, so as to avoid the cover 1 automatically resetting and closing with the bin 2 during the opening process, causing problems such as pinching the hand and paper jams to affect the operation. At the same time, the contact surface between the limiting member 21 and the limiting portion 31 is an arc surface, so that the engaging fit between the limiting member and the limiting portion can be released only when an external force is applied to the cover.

[0058] Please refer to Figure 2 , the first end of the rotating body 3 is circular, and a rotating shaft 32 is arranged at the center of the circle, and a limiting portion 31 is arranged on the circumference of the circle; wherein the rotating shaft 32 can be arranged on the center of the outer side or the center of the inner side of the rotating body 3; at the same time, the abutting surface between the limiting portion 31 and the limiting member 21 is an arc surface. In an optional embodiment, the cover body 1 can be integrally formed with the rotating body 3; that is, the first end of the rotating body 3 and the cover body 1 are integral, so that the rotation of the cover body 1 is more stable. In another optional embodiment, the cover body 1 and the rotating body 3 are separately formed. Figure 1 as well as Figure 2 As shown, a fixing buckle 33 is provided at the first end of the rotating body 3, and a fixing hole 11 is provided on the cover body 1. The fixing buckle 33 cooperates with the fixing hole 11 to achieve a fixed connection between the first end of the rotating body 3 and the cover body 1, so that when the limiting part 31 of the rotating body 3 is worn, it can be easily replaced.

[0059] Please refer to Figure 3 as well as Figure 4The bin body 2 is provided with an avoidance groove 22, which corresponds to the position of the second end of the rotating body 3; the depth of the avoidance groove 22 is greater than the height of the limiting portion 31, so that the limiting portion 31 can rotate in the avoidance groove 22; at the same time, the limiting member 21 is provided at the first end of the avoidance groove 22; the first end of the avoidance groove 22 is close to the opening end of the cover body 1. That is, when the limiting portion 31 of the rotating body 3 moves toward the direction of the limiting member 21, the cover body 1 is in the process of opening the cover. By providing the avoidance groove 22, it is avoided that the limiting portion 31 interferes with the bin body 2 due to the protrusion of the limiting portion 31, and cannot rotate smoothly.

[0060] The warehouse body 2 is also provided with a rotating frame 23; the rotating shaft 32 is mounted on the rotating frame 23. Figure 4 As shown, taking the case where the rotating shaft 32 is arranged on the center of the circle inside the rotating body 3 as an example, the rotating frame 23 is also arranged on the inner side of the avoidance groove 22, so that the limiting portion 31 on the rotating body 3 forms a match with the avoidance groove 22, and the rotating shaft 32 also forms a match with the rotating frame 23. If the rotating shaft 32 is arranged on the center of the circle outside the rotating body 3, the rotating frame 23 is arranged on the outer side of the avoidance groove 22. Among them, the rotating frame 23 is half-open, so that the rotating shaft 32 has a certain displacement margin, so that when the limiting portion 31 rotates to the position that cooperates with the limiting member 21, the rotating shaft 32 can be slightly displaced to achieve the clamping fit between the limiting portion 31 and the limiting member 21.

[0061] In an optional embodiment, the limiting member 21 is a right-angled trapezoidal structure. Figure 3 as well as Figure 4 As shown, the right-angled side of the stopper 21 is arranged on the bin body 2; the height of the side close to the avoidance groove 22 is lower than the height of the side away from the avoidance groove 22; wherein, the bottom surface of the avoidance groove 22 is an arc surface, and its curvature is adapted to the curvature of the first end of the rotating body 3. At the same time, the side of the stopper 21 close to the avoidance groove 22 is an arc surface, and the side of the stopper 21 away from the avoidance groove 22 is a plane, that is, the two bottom surfaces of the stopper 21 are connected by the arc surface.

[0062] Please refer to Figure 1 as well as Figure 6 In the initial state, the cover body 1 and the bin body 2 are covered, and the limiting portion 31 is located in the avoidance groove 22. When the cover is opened, the limiting portion 31 moves in the avoidance groove 22 along the direction of the limiting member 21. When the limiting portion 31 is separated from the avoidance groove 22 and moves to the top or rear end of the limiting member 21, the limiting portion 31 and the limiting member 21 are snap-fitted, and the cover is completely opened at this time, and it will not automatically reset. At the same time, the contact surface between the limiting member and the limiting portion is an arc surface in the present application. Therefore, as long as an external force is applied to the cover body 1, the snap-fit ​​between the limiting member 21 and the limiting portion 31 can be released, and the process of closing the cover can be completed.

[0063] Embodiment 2

[0064] An electronic device includes the device for preventing the cover body 1 from automatically resetting after opening the cover in Embodiment 1. For example, in a specific application scenario, the device for preventing the cover body 1 from automatically resetting after opening the cover in Embodiment 1 is used as a handheld printer.

[0065] Please refer to Figure 4 The cover 1 and the bin 2 are both parts of the handheld printer; the cover 1 of the device is the paper bin cover of the handheld printer; and the bin 2 is the paper bin of the handheld printer. Figure 4 As shown, the printer is in the cover-opening state, at which the limiting portion 31 on the rotating body 3 and the limiting member 21 on the housing 2 form a snap fit, so that the cover 1 cannot slide the limiting portion 31 into the avoidance groove 22 under the action of its own gravity, thereby preventing the cover 1 from automatically resetting during the cover-opening process. When the cover needs to be closed, the cover 1 needs to be pressed by external force to close the cover 1 with the housing 2.

[0066] Please refer to Figure 5 For example, when the electronic device is a POS machine, the POS machine includes an operation terminal and a printer connected to the operation terminal, so that a printing operation can be performed during the use of the POS machine.

[0067] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
