It can be appreciated that the electrical connector 420 is made of conductive metal, the contact portion 421 protrudes toward the mounting cavity 101 relative to the swinging member 410, the contact portion 421 may have a contact electrically connected to a chip contact, when the cover 200 covers and closes the mounting cavity 101, the cover 200 may abut against the swinging member 410 and force the swinging member 410 to swing toward the mounting cavity 101, so that the contact portion 421 enters the mounting cavity 101, and the contact of the contact portion 421 may contact the chip contact, thereby realizing the electrical connection between the electrical connector 420 and the chip contact.

It should be noted that, the swinging member 410 may have a rod-shaped structure, and one end of the swinging member 410 may be used as a rotation center of the swinging member, and when the swinging member 410 rotates, a track surface covered by the swinging member 410 is an arc surface, and a moving distance of the electrical connection member 420 relative to the mounting cavity 101 depends on a rotation amplitude of the swinging member 410 and a distance between the electrical connection member 420 and the rotation center of the swinging member 410. The specific structure and installation manner of the swing member 410 will be described in detail.

Fig. 7 is a schematic structural diagram of a swinging member in a printing apparatus according to an embodiment of the present utility model, fig. 8 is a schematic assembly diagram of the swinging member on a device main body in the printing apparatus according to the embodiment of the present utility model, and fig. 9 is a side view of the assembly of the swinging member on the device main body in the printing apparatus according to the embodiment of the present utility model.

Referring to fig. 7 to 9, and referring to fig. 2 to 6, in one possible implementation manner, the apparatus main body 100 may include a fixed base 120, a first end of the swinging member 410 may be rotatably connected to the fixed base 120, a second end of the swinging member 410 may extend toward the cover 200, and the cover 200 may be abutted to or separated from the second end of the swinging member 410 by opening and closing the cover relative to the apparatus main body 100, so that the swinging member 410 rotates relative to the fixed base 120.

Wherein, the opening of the installation cavity 101 may be disposed upward, and the case cover 200 may be disposed above the apparatus body 100 to be opposite to the opening of the installation cavity 101. The swinging member 410 may be approximately vertically disposed at a side of the installation cavity 101 and located at an outer side of the installation cavity 101, the first end of the swinging member 410 is a lower end of the swinging member 410, the fixed base 120 may be fixedly connected to the apparatus main body 100 by a fastener such as a screw, and the first end of the swinging member 410 is connected to the fixed base 120 by a rotating shaft, so as to implement reciprocating swinging of the swinging member 410 along a specific track on the apparatus main body 100 along with opening and closing of the cover 200.

It will be appreciated that when the cover 200 abuts the second end of the swinging member 410, the cover 200 forces the swinging member 410 to swing toward the direction of the mounting cavity 101, and when the cover 200 is opened, the cover 200 is separated from the swinging member 410, and the swinging member 410 can be reset by other driving forces, and the driving force providing components include, but are not limited to, active driving units such as a motor, and components providing thrust such as a spring.

In some embodiments, the second end of the swinging member 410 has a pushing portion 411, and when the cover 200 abuts against the pushing portion 411, the cover 200 may apply a pushing force to the pushing portion 411 to rotate the swinging member 410 toward the mounting cavity 101, that is, a downward force when the cover 200 is closed may cause the swinging member 410 to generate a torque that rotates toward the mounting cavity 101.

Since the mounting mode and the opening and closing mode of the cover 200 with respect to the apparatus main body 100 may be rotational opening and closing or may be detachable mounting, the movement track of the cover 200 during opening and closing may be an arc line, a straight line, or a combination of an arc line and a straight line implemented by a link mechanism, and the movement track of the swinging member 410 may be an arc line rotating around the first end rotation axis thereof, so that when the cover 200 generates thrust to the thrust pushing portion 411, the cover 200 may slide with respect to the thrust pushing portion 411, that is, the thrust pushing portion 411 may perform a guiding function on the relative movement of the housing and the swinging member 410.

For example, the housing cover 200 may be provided with an abutting portion 210, the pushing portion 411 has a pushing surface 4111, the abutting portion 210 abuts against the pushing surface 4111, and the pushing surface 4111 has an inclination angle with respect to the opening and closing direction of the housing cover 200, so that when the housing cover 200 abuts against the pushing portion 411, the pushing direction of the housing cover 200 against the pushing portion 411 may have an included angle with the pushing surface 4111, and further, a component force of the pushing force of the housing cover 200 against the pushing portion 411 in a direction perpendicular to the surface direction of the pushing surface 4111 may push the swing member 410 to rotate.

It should be noted that, the pushing portion 411 may have a certain inclination angle with respect to the main structure of the swinging member 410, and the pushing portion 411 may be bent at a certain angle with respect to the main structure of the swinging member 410 toward the direction of the safety cavity, so that when the cover 200 abuts against the pushing surface 4111 of the pushing portion 411 to generate a pushing force, an extension line of the pushing force may not pass through the rotation center of the swinging member 410, that is, in the process of pushing the swinging member 410 by the cover 200 to rotate, the rotation center of the swinging member 410 is always spaced from the extension line of the pushing force, so that the pushing force of the cover 200 to the swinging member 410 may form a torque, and the occurrence of a locking condition is prevented.

The structure of resetting the swinging member 410 to separate the electrical connector 420 from the chip contacts when the cover 200 is opened with respect to the apparatus main body 100 will be described in detail.

Referring to fig. 1 to 9, in one possible implementation, the electrical connection assembly 400 may further include a first elastic member 430, where the first elastic member 430 is located between the apparatus main body 100 and the swinging member 410, and the first elastic member 430 may apply a pushing force to the swinging member 410 to rotate the swinging member 410 in a direction away from the mounting cavity 101.

One end of the first elastic member 430 may abut against the apparatus main body 100, for example, the first elastic member 430 may abut against an outer sidewall of the side plate 110, the other end of the first elastic member may abut against the swinging member 410, a limiting portion may be disposed on the swinging member 410, and one end of the first elastic member 430 abutting against the swinging member 410 may be engaged with the limiting portion. For example, the limiting portion may be a groove of the swinging member 410 facing one side surface of the mounting cavity 101, the groove is provided with a positioning column, and an end portion of the first elastic member 430 may be sleeved on the positioning column and clamped with a circumferential groove wall of the groove, so as to ensure reliability of connection between the first elastic member 430 and the swinging member 410.

It will be appreciated that the position where the first elastic member 430 abuts on the swinging member 410 and the position where the cover 200 abuts on the swinging member 410 may be located on the same side of the rotation center of the swinging member 410, and the surface where the pushing surface 4111 abuts on the swinging member 410 and the first elastic member 430 are located on opposite sides of the swinging member 410, so that the torque generated by the pushing force of the first elastic member 430 on the swinging member 410 is opposite to the torque generated by the pushing force on the swinging member 410 when the cover 200 is closed, and when the cover 200 is opened, and the cover 200 is separated from the pushing portion 411, the swinging member 410 may be reset by pushing the pushing force of the swinging member 410 by the first elastic member 430, so that the electrical connector 420 is separated from the chip contact, and the contact portion 421 exits the mounting cavity 101.

For example, the first elastic member 430 may be a spring, which may be a compression spring, and when the cover 200 is closed, the cover 200 forces the swing member 410 to rotate, so that the swing member 410 compresses the spring, and when the cover 200 is opened, the spring rebounds to push the swing member 410 to return. The first elastic member 430 may also be made of other elastic materials or components, which are not particularly limited in the embodiment of the present utility model.

In some embodiments, the electrical connector 420 may include a second elastic member 422, where the device body 100 is provided with an electrical connection substrate 130, the electrical connection substrate 130 is located on a side of the fixed base 120 away from the swinging member 410, a first end of the second elastic member 422 is connected to the electrical connection substrate 130, and a second end of the second elastic member 422 is connected to the swinging member 410; the second elastic member 422 applies a pushing force to the swinging member 410 toward the mounting chamber 101.

It can be understood that the electrical connector 420 has elasticity, so that after the cover 200 is covered, the electrical connector 420 can ensure the reliability of the contact between the electrical connector 420 and the chip contact through self elasticity, and the electrical connection substrate 130 can be fixedly arranged on the device main body 100, so that the first end of the electrical connector 420 is fixed relative to the device main body 100, and the second end of the electrical connector 420 moves along with the rotation of the swinging member 410, therefore, as the cover 200 is opened and closed, the swinging member 410 swings reciprocally, the electrical connector 420 needs to stretch and contract, and the main body structure of the electrical connector 420 is formed through the second elastic member 422, so that the reliability of the electrical connection performance of the electrical connector 420 can be always maintained in the process of entering the mounting cavity 101 to contact with the chip contact and pushing out the mounting cavity 101.

The second elastic member 422 may be a contact wire spring, so that the second elastic member 422 may have good electrical conductivity while having good expansion and contraction properties, so as to realize transmission of electrical signals between the chip contacts and the electrical connection substrate 130.

In some embodiments, the second elastic members 422 may be plural, and the plural second elastic members 422 are arranged at intervals along the height direction of the swing member 410. The end of each second elastic member 422 has a contact portion 421 connected thereto so that each second elastic member 422 can make a contact between the electrical connector 420 and the chip contact. The number of the second elastic members 422 may be two, three, four, or more, which is not particularly limited in the embodiment of the present utility model.

It is understood that the torque generated by the thrust of the first elastic member 430 to the swing member 410 may be greater than the sum of the torques generated by the thrust of the plurality of second elastic members 422 to the swing member 410. When the cover 200 is opened relative to the apparatus main body 100 and the cover 200 is separated from the swinging member 410, the first elastic member 430 is required to push the swinging member 410 to swing away from the mounting cavity 101, and in this process, the swinging member 410 drives the electrical connection member 420 to move out of the mounting cavity 101, so that the second elastic member 422 is compressed, and therefore, the torque formed by the thrust of the second elastic member 422 to the swinging member 410 is greater than the sum of the torques formed by the thrust of the plurality of second elastic members 422 to the swinging member 410, so that the smoothness of resetting the swinging member 410 can be improved.

It should be noted that, the printing apparatus 10 provided in the embodiment of the present utility model includes an apparatus main body 100, a cover 200, and an electrical connection assembly 400, where the apparatus main body 100 and the cover 200 enclose a mounting cavity 101 for mounting the cartridge 300, the cover 200 can open or cover the opening of the mounting cavity 101 with respect to the apparatus main body 100, the cartridge 300 is detachably disposed in the mounting cavity 101, the electrical connection assembly 400 is disposed at a side of the mounting cavity 101, the electrical connection assembly 400 includes a swinging member 410 and an electrical connection member 420 for electrically connecting with a chip contact of the cartridge 300, the electrical connection member 420 is connected with the swinging member 410, and the swinging member 410 is rotationally connected with the apparatus main body 100; when the cover 200 is covered, the cover 200 is abutted against the swinging member 410, so that the swinging member 410 drives the electric connecting member 420 to rotate to a position capable of contacting with the chip, and when the cover 200 is opened, the cover 200 is separated from the swinging member 410, so that the swinging member 410 drives the electric connecting member 420 to rotate to a position at least partially separated from the chip, thereby avoiding dust generated by extrusion friction between the chip and the electric connecting member 420, and simultaneously avoiding the electric connecting member 420 from being stained with carbon powder in the selenium drum 300, and reliable electric connection between the electric connecting member 420 and the chip can be realized.
