[0048] In order to make the objects, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in conjunction with the accompanying drawings.

[0049] The following description refers to the accompanying drawings. Unless otherwise indicated, like numbers in the various drawings of the drawings denote like or similar elements. The following description, given together with the accompanying drawings, is a description of exemplary embodiments of the present application and does not represent all embodiments in accordance with the present application. Rather, they are merely examples of apparatuses and methods in accordance with some aspects of the present application as detailed in the appended claims.

[0050] In the related art, a printer generally comprises a body and a cover, one end of the cover is rotatably connected with the body, and the other end is provided with a limiting structure. When the cover is closed with the body, the limiting structure is used to limit and fix the cover and the body. In order to improve the stability of the cover, a plurality of limiting structures are generally arranged along the rotation axis direction of the cover to limit together.

[0051] When a plurality of limiting structures limit together, the stability of the cover can be improved. However, in the process of opening and closing the cover, the stress sequence, size, direction and the like of different parts may not be consistent, which can easily cause the limiting structures of different parts to be out of synchronization when limiting and releasing the limit, thereby causing the opening and closing operation of the cover to be not smooth.

[0052] To solve the above problems, the present application provides a printer, a plurality of limiting members are arranged on the body in a spaced manner, and when the cover is closed with the body, the plurality of limiting members are connected with the cover for limiting. On this basis, the plurality of limiting members are connected through a linkage assembly, so that the plurality of limiting members can be connected or separated with the cover synchronously, thereby making the limiting and releasing of the limiting of different parts be synchronized, and further making the cover be able to be closed and opened more smoothly.

[0053] Referring to Figure 1 and Figure 2 , the printer 1 of the embodiments of the present application comprises a body 10, a cover 20 and a clamping structure 30.

[0054] Referring to Figure 3 and Figure 4 The shape, size and material of the body 10 and the cover 20 are not limited and can be adjusted according to design requirements.

[0055] The cover 20 is movably connected to the body 10 and can be covered with the body 10. For example, the cover 20 is clamped with the body 10. For another example, one end of the cover 20 is rotatably connected with the body 10, and the other end is clamped with the body 10. The cover 20 is provided with a matching part 21, and the matching part 21 has a first matching part 211 and a second matching part 212, both of which are used for limiting cooperation with the body 10.

[0056] In combination Figure 2 , Figure 4 to Figure 6 The clamping structure 30 includes a first limiting part 31, a second limiting part 32 and a linkage assembly 33. The first limiting part 31 and the second limiting part 32 are spaced apart on the body 10, the first limiting part 31 can be limitedly matched with the first matching part 211, and the second limiting part 32 can be limitedly matched with the second matching part 212, so as to limit and fix the cover 20 and the body 10 when the cover 20 is covered with the body 10.

[0057] The linkage assembly 33 connects the first limiting part 31 and the second limiting part 32, and the linkage assembly 33 can drive the first limiting part 31 and the second limiting part 32 to move synchronously, so that the first matching part 211 and the first limiting part 31 are limitedly matched at the same time, the second matching part 212 and the second limiting part 32 are limitedly matched, and the first matching part 211 and the first limiting part 31 are released from the limitation at the same time, and the second matching part 212 and the second limiting part 32 are released from the limitation. In this way, the first limiting part 31 and the second limiting part 32 can be connected or separated from the cover 20 synchronously, so that the limitation and release of different parts are synchronized, and the cover 20 can be more smoothly covered and opened.

[0058] In some embodiments, the first limiting part 31 and the second limiting part 32 are spaced apart along a first direction X1. One end of the cover 20 is rotatably connected with the body 10 along a second direction X2, and the other end is provided with the matching part 21. Wherein, the first direction X1 intersects with the second direction X2.

[0059] It can be understood that since the cover 20 is rotatably connected with the body 10, the position of the cover 20 will change during opening and covering, therefore, the second direction X2 will change with the position change of the cover 20. However, the included angle between the second direction X2 and the first direction X1 does not change with the position change of the cover 20. For example, the included angle between the second direction X2 and the first direction X1 is a right angle.

[0060] Based on this, since one end of the cover 20 is rotationally connected with the body 10, the cover 20 is connected with the body 10 in both the open state and the closed state, and the cover 20 can be prevented from being lost after being opened. At the same time, the matching part is arranged at the other end of the cover 20, that is, the distance between the matching part and the rotationally connected part is far, and the moment is long, so that the cover 20 is more labor-saving in the opening and closing process. Furthermore, since the first limiting part 31 and the second limiting part 32 are arranged along the first direction X1, for example, the width direction or the length direction of the cover 20, different parts of the cover 20 in the width direction can be limited, so as to improve the stability of the cover 20 in the closed state.

[0061] In combination Figure 2 , Figure 5 and Figure 6 , in some embodiments, the linkage assembly 33 includes a third limiting part 331, a fourth limiting part 332, and a fifth limiting part 333. The third limiting part 331 is connected with the first limiting part 31, the fourth limiting part 332 is connected with the second limiting part 32, and the two ends of the fifth limiting part 333 are fixedly connected with the third limiting part 331 and the fourth limiting part 332, respectively. The fifth limiting part 333 is movable relative to the body 10 to drive the first limiting part 31 and the second limiting part 32 to move synchronously relative to the body 10.

[0062] Based on this, in the process of opening and closing the cover 20, when one of the first limiting part 31 and the second limiting part 32 is moved relative to the matching part 21 under the action of force, the linkage assembly 33 drives the other of the first limiting part 31 and the second limiting part 32 to move relative to the matching part 21, so that the cover 20 can be more smoothly closed and opened.

[0063] In some embodiments, the third limiting part 331 is slidingly connected with the first limiting part 31, the fourth limiting part 332 is slidingly connected with the second limiting part 32, and the third limiting part 331 and the fourth limiting part 332 are rotationally connected with the body 10. In this way, in the process of driving the first limiting part 31 and the second limiting part 32 to move synchronously by the linkage assembly 33, the relative positional relationship between the third limiting part 331 and the first limiting part 31 and between the fourth limiting part 332 and the second limiting part 32 can be flexibly adjusted along with the movement process, so that the movement of the first limiting part 31 and the second limiting part 32 is more flexible.

[0064] In some embodiments, the third limiting piece 331 is fixedly connected with the first limiting piece 31, the fourth limiting piece 332 is fixedly connected with the second limiting piece 32, the third limiting piece 331 is rotatably connected with the fuselage 10, and the fourth limiting piece 332 is rotatably connected with the fuselage 10. In this way, during the process of the linkage assembly 33 driving the first limiting piece 31 and the second limiting piece 32 to move synchronously, the relative position relationship between the third limiting piece 331 and the fuselage 10 and between the fourth limiting piece 332 and the fuselage 10 can be flexibly adjusted along with the movement process, so that the movement of the first limiting piece 31 and the second limiting piece 32 is more flexible.

[0065] In some embodiments, the first limiting piece 31 and the second limiting piece 32 are arranged at intervals along the first direction X1, and the extension direction of the fifth limiting piece 333 is parallel to the first direction X1. In this way, the distance between the fifth limiting piece 333 and the first limiting piece 31 and the distance between the fifth limiting piece 333 and the second limiting piece 32 are equal, so that the force distribution of the fifth limiting piece 333 on the first limiting piece 31 and the second limiting piece 32 is more uniform, thereby making the movement of the first limiting piece 31 and the second limiting piece 32 more synchronous.

[0066] In some embodiments, the first limiting piece 31 and the second limiting piece 32 are respectively located on both sides of the virtual axis L and are mirror-symmetric, the third limiting piece 331 and the fourth limiting piece 332 are respectively located on both sides of the virtual axis L and are mirror-symmetric, and the central axis of the fifth limiting piece 333 is collinear with the virtual axis L. In this way, the moment of force between the first limiting piece 31 and the third limiting piece 331 and the moment of force between the second limiting piece 32 and the fourth limiting piece 332 are equal, and the moment of force between the third limiting piece 331 and the fifth limiting piece 333 and the moment of force between the fourth limiting piece 332 and the fifth limiting piece 333 are equal, so that the force on the first limiting piece 31 and the second limiting piece 32 is more balanced, thereby making the movement of the first limiting piece 31 and the second limiting piece 32 more synchronous.

[0067] Optionally, the first limiting piece 31 and the second limiting piece 32 are the same in shape and the same in material, and the third limiting piece 331 and the fourth limiting piece 332 are the same in shape and the same in material. In this way, the force during the movement of the first limiting piece 31 and the second limiting piece 32 is more balanced.

[0068] In combination Figure 2 and Figure 6In some embodiments, the printer 1 further comprises a resetting assembly 40 arranged at at least one of the first limiting member 31, the second limiting member 32 and the linkage assembly 33 to drive the first limiting member 31 and the second limiting member 32 to reset after the external force driving the first limiting member 31 and the second limiting member 32 to move relative to the body 10 disappears. In this way, the position change of the first limiting member 31 and the second limiting member 32 caused by the action of opening the cover 20 can be automatically eliminated after the cover 20 is opened, thereby simplifying the operation steps of the user to close the cover 20 and improving the user experience.

[0069] In some embodiments, the resetting assembly 40 comprises a first elastic member (not shown in the figure), such as a spring. The first limiting member 31 and the body 10 are respectively connected to two ends of the first elastic member and compress the first elastic member. In this way, the resetting of the first limiting member 31 is realized through the first elastic member, and the second limiting member 32 can also be reset, which is simple in structure and low in cost.

[0070] In some embodiments, the resetting assembly 40 comprises a second elastic member (not shown in the figure), such as a spring. The second limiting member 32 and the body 10 are respectively connected to two ends of the second elastic member and compress the second elastic member. In this way, the resetting of the second limiting member 32 is realized through the second elastic member, and the first limiting member 31 can also be reset, which is simple in structure and low in cost.

[0071] Reference Figure 6 In some embodiments, the resetting assembly 40 comprises a third elastic member 41, and the linkage assembly 33 and the body 10 are respectively connected to two ends of the third elastic member 41 and compress the third elastic member 41. In this way, the resetting of the first limiting member 31 and the second limiting member 32 is realized through the third elastic member 41, which is simple in structure and low in cost.

[0072] Optionally, the first elastic member, the second elastic member and the third elastic member 41 can exist simultaneously, or two of them can exist simultaneously, or one of them can exist alone. When the first elastic member, the second elastic member and the third elastic member 41 exist simultaneously, the first limiting member 31, the second limiting member 32 and the linkage assembly 33 can all be subjected to elastic restoring force, so that the resetting effect is better. When two of the first elastic member, the second elastic member and the third elastic member 41 exist simultaneously, for example, when the first elastic member and the second elastic member exist simultaneously, the resetting effect is better, and the overall structure is simplified. When one of the first elastic member, the second elastic member and the third elastic member 41 exists alone, the overall structure is simpler.

[0073] Optionally, the third elastic member 41 is provided with two, and the two third elastic members 41 are connected to the third limiting member 331 and the fourth limiting member 332 respectively. In this way, the third limiting member 331 and the fourth limiting member 332 can be subjected to more balanced elastic force, so that the first limiting member 31 and the second limiting member 32 are subjected to more balanced force, and thus the first limiting member 31 and the second limiting member 32 can be better synchronized to reset.

[0074] With reference to Figure 6 In some embodiments, at least one of the first limiting member 31, the second limiting member 32 and the linkage assembly 33 is provided with a positioning structure 42, and the corresponding reset assembly 40 is inserted and positioned with the positioning structure 42. For example, the third limiting member 331 and the fourth limiting member 332 are both provided with a slot, and the reset assembly 40 includes two springs which are respectively inserted into the slot of the third limiting member 331 and the slot of the fourth limiting member 332. In this way, under the positioning action of the positioning structure 42, the installation of the reset assembly 40 is more convenient and fast, and the force direction of the reset assembly 40 is not easy to be inclined, so that the reset assembly 40 can more effectively play a reset role.

[0075] Optionally, the body 10 is provided with a limiting column, and one end of the spring is sleeved on the limiting column. In this way, the stability of the spring can be further improved, so that it can more effectively play a reset role.

[0076] Optionally, the limiting column is provided with a reinforcing rib, so as to improve the structural strength thereof.

[0077] Optionally, a plurality of reinforcing ribs, for example, two, three or four reinforcing ribs, are circumferentially spaced apart on the limiting column, so as to further improve the structural strength thereof.

[0078] Further, the plurality of reinforcing ribs are uniformly spaced apart along the circumference of the limiting column. In this way, on the one hand, the structural strength of the limiting column is higher, and on the other hand, when the spring is sleeved on the limiting column, the radial force between the spring and the limiting column is more evenly distributed.

[0079] In combination Figure 2 , Figure 6 to Figure 8 In some embodiments, the body 10 has opposite inner and outer sides, and the linkage assembly 33 is arranged on the inner side. In this way, the linkage assembly 33 is hidden in the inner side, so as to improve the safety performance of the printer 1.

[0080] The body 10 is provided with an operating member 11, and the linkage assembly 33 is provided with a transmission member 12 opposite to the operating member 11. One end of the operating member 11 is exposed to the outside, and the other end extends into the inner side and can be moved under the action of an external force and generate a pressing force on the transmission member 12, so as to drive the first limiting member 31 and the second limiting member 32 to be synchronized with the cover 20. In this way, the user's operation of opening the cover 20 is more convenient.

[0081] In some embodiments, the operation member 11 is provided with a first abutting surface 111 facing the transmission member 12, and the transmission member 12 is provided with a second abutting surface 121 facing the operation member 11. The first abutting surface 111 and the second abutting surface 121 are both configured as non-planar surfaces, and the first abutting surface 111 and the second abutting surface 121 can be adapted to each other. By configuring the first abutting surface 111 and the second abutting surface 121 as non-planar surfaces, the contact area between the first abutting surface 111 and the second abutting surface 121 is increased, so that when the first abutting surface 111 and the second abutting surface 121 abut against each other, the friction between the first abutting surface 111 and the second abutting surface 121 is larger, thereby more effectively avoiding the first abutting surface 111 and the second abutting surface 121 from slipping and dislocating, and further making the cover opening operation more sensitive.

[0082] Optionally, one of the first abutting surface 111 and the second abutting surface 121 is configured as a concave surface, and the other is configured as a convex surface, so that the first abutting surface 111 and the second abutting surface 121 can stably abut against each other.

[0083] Optionally, the first abutting surface 111 and the second abutting surface 121 are both configured as curved surfaces, such as arc surfaces. In this way, the stability of the abutment between the first abutting surface 111 and the second abutting surface 121 is improved, and the structure is simplified.

[0084] Optionally, the first abutting surface 111 and the second abutting surface 121 are both configured as non-planar surfaces composed of multiple planar surfaces, such as V-shaped surfaces composed of two planar surfaces. In this way, the stability of the abutment between the first abutting surface 111 and the second abutting surface 121 is improved, and the structure is simplified.

[0085] In combination with Figure 3 , Figure 4 and Figure 9 , in some embodiments, the printer 1 further comprises an elastic driving member 50, such as a torsion spring, connected to the body 10 and the cover 20. The elastic driving member 50 is configured to drive the cover 20 to open after the first limiting member 31 and the second limiting member 32 are separated from the cover 20. In this way, after the first limiting member 31 and the second limiting member 32 are synchronously separated from the cover 20, the cover 20 can be automatically popped up under the action of the elastic driving member 50, thereby simplifying the operation steps of the user.

[0086] In combination with Figure 2 , Figure 10 , Figure 11 , in some embodiments, the printer 1 further comprises a limiting frame 60 for limiting at least one of the first limiting member 31, the second limiting member 32, and the linkage assembly 33 to limit it from deviating from a preset range of motion. In this way, during the opening and closing of the cover 20, the first limiting member 31, the second limiting member 32, and the linkage assembly 33 can move within the preset range of motion, thereby avoiding situations such as jamming and disengagement.

[0087] In combination with Figure 6 , Figure 10 and Figure 11In some embodiments, the first limiting member 31 and the second limiting member 32 are spaced apart along the first direction X1. The linkage assembly 33 comprises a third limiting member 331, a fourth limiting member 332 and a fifth limiting member 333 connected in sequence, the third limiting member 331 and the fourth limiting member 332 are spaced apart along the first direction X1, and the fifth limiting member 333 extends along the first direction X1. The first limiting member 31 is connected to the third limiting member 331 along the third direction X3, and the second limiting member 32 is connected to the fourth limiting member 332 along the third direction X3. The limiting frame 60 has a first side 61 and a second side 62 opposite along the fourth direction X4; the first limiting member 31 and the second limiting member 32 are located on the first side 61, and the fifth limiting member 333 is located on the second side 62; the third limiting member 331 and the fourth limiting member 332 both penetrate the limiting frame 60, and each of the third limiting member 331 and the fourth limiting member 332 has a part on the first side 61 and another part on the second side 62. The first direction X1, the third direction X3 and the fourth direction X4 intersect with each other, for example, the first direction X1, the third direction X3 and the fourth direction X4 are perpendicular to each other. In this way, the relative movement of the first limiting member 31, the second limiting member 32, the third limiting member 331, the fourth limiting member 332 and the fifth limiting member 333 along the three-dimensional space is limited by the limiting frame 60.

[0088] Specifically, since the third limiting member 331 and the fourth limiting member 332 both penetrate the limiting frame 60, and the third limiting member 331 and the fourth limiting member 332 are spaced apart along the first direction X1, the third limiting member 331 and the fourth limiting member 332 cannot move out of the preset movement range along the first direction X1, so that the first limiting member 31 connected to the third limiting member 331 and the second limiting member 32 connected to the fourth limiting member 332 cannot move out of the preset movement range along the first direction X1.

[0089] In addition, since the third limiting member 331 and the fourth limiting member 332 both penetrate the limiting frame 60, and each of the third limiting member 331 and the fourth limiting member 332 has a part on the first side 61 of the limiting frame 60 along the fourth direction X4 and another part on the second side 62 of the limiting frame 60 along the fourth direction X4, the third limiting member 331 and the fourth limiting member 332 cannot move out of the preset movement range along the fourth direction X4.

[0090] Optionally, the limiting frame 60 is provided with two mounting holes extending along the first direction X1 and spaced apart along the first direction X1, and the fifth limiting member 333 is configured in a cylindrical shape, and the two ends of the fifth limiting member 333 are respectively inserted into the two mounting holes of the limiting frame 60. In this way, the limiting frame 60 can limit the movement of the fifth limiting member 333, so that the first limiting member 31, the second limiting member 32, the third limiting member 331 and the fourth limiting member 332 cannot move out of the preset movement range along the third direction X3.

[0091] Optionally, the limiting frame 60 is provided with a limiting column, and the reset assembly 40 comprises a spring which is sleeved on the limiting column, so as to improve the stability of the spring and make the reset function more effective.

[0092] In some embodiments, the first limiting piece 31 is provided with a first clamping groove 311, and the second limiting piece 32 is provided with a second clamping groove 321. The cooperation piece 21 is a connecting shaft, the first cooperation part 211 and the second cooperation part 212 are respectively located at two ends of the connecting shaft, the first cooperation part 211 can be clamped in the first clamping groove 311, and the second cooperation part 212 can be clamped in the second clamping groove 321. In this way, the covering process of the cover body 20 and the machine body 10 is more simple, and the limiting effect is stable when the cover body 20 is covered.

[0093] In some embodiments, the first limiting piece 31 is configured to rotate relative to the machine body 10 when subjected to the action force of the connecting shaft, and change the orientation of the first clamping groove 311, so that the connecting shaft can be clamped into or out of the first clamping groove 311. In this way, the first limiting piece 31 can more flexibly adjust the orientation according to the force condition, so that the clamping process between the first limiting piece 31 and the connecting shaft is more smooth, and the covering process of the cover body 20 is more smooth.

[0094] In some embodiments, the second limiting piece 32 is configured to rotate relative to the machine body 10 when subjected to the action force of the connecting shaft, and change the orientation of the second clamping groove 321, so that the connecting shaft can be clamped into or out of the second clamping groove 321. In this way, the second limiting piece 32 can more flexibly adjust the orientation according to the force condition, so that the clamping process between the second limiting piece 32 and the connecting shaft is more smooth, and the covering process of the cover body 20 is more smooth.

[0095] Reference Figure 11 In some embodiments, the first limiting piece 31 is provided with a first guide surface 312 located at the edge of the first clamping groove 311, and the first guide surface 312 is configured to change the orientation when the connecting shaft moves towards the first clamping groove 311, so as to guide the connecting shaft into the first clamping groove 311. In this way, the connecting shaft is more smoothly guided into the first clamping groove 311 by the guiding action of the first guide surface 312, so that the covering process of the cover body 20 is more smooth.

[0096] In some embodiments, the second limiting piece 32 is provided with a second guide surface (not shown in the figure) located at the edge of the second clamping groove 321, and the second guide surface is configured to change the orientation when the connecting shaft moves towards the second clamping groove 321, so as to guide the connecting shaft into the second clamping groove 321. In this way, the connecting shaft is more smoothly guided into the second clamping groove 321 by the guiding action of the second guide surface, so that the covering process of the cover body 20 is more smooth.

[0097] In combination Figure 4 And Figure 6In some embodiments, the main body 10 is provided with a paper bin, and the printer 1 further comprises a printing roller 70, when the cover 20 is covered with the main body 10, the printing roller 70 is located at a paper outlet of the paper bin to define a paper outlet direction of the paper bin. Wherein, the printing roller 70 is sleeved on the connecting shaft, and the printing roller 70 can rotate around the axis of the connecting shaft relative to the cover 20. In this way, the printing roller 70 and the connecting shaft occupy less space, and the connection structure among the printing roller 70, the connecting shaft and the cover 20 is simplified.
