[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0058] According to the first aspect of the present application, referring to Figures 1 to 7The present application provides a locking device 100, which is used to lock the base 200 and the part to be locked 300, thereby ensuring the relative fixation of the positions of the base 200 and the part to be locked 300, avoiding relative displacement between the two and shaking of the part to be locked 300.

[0059] refer to Figures 1 to 5 The locking device 100 includes a locking member 110 and an unlocking member 120 , which are arranged between a base 200 and a member to be locked 300 .

[0060] The locking member 110 is formed or connected to one of the base 200 and the member to be locked 300, and the contact member is formed or connected to the other of the base 200 and the member to be locked 300. The locking member 110 is used to apply a locking force to the other of the base 200 and the member to be locked 300, so that the locking member 110 can be maintained in a locked position relative to the base 200. The unlocking member 120 is used to apply an unlocking force to one of the base 200 and the member to be locked 300, and the unlocking force is used to overcome the locking force, so that the member to be locked 300 can be allowed to rotate relative to the base 200 and rotate a certain angle to a required position.

[0061] In some embodiments, when the locking member 110 is formed or connected to the base 200 and the member to be locked 300, the unlocking member 120 is formed or connected to the base 200 and the member to be locked 300, and the locking member 110 located on the base 200 applies a locking force to the member to be locked 300 to keep the base 200 and the member to be locked 300 in the locked position.

[0062] When the unlocking member 120 located at the member to be locked 300 applies an unlocking force to the base 200 that can overcome the locking force, the member to be locked 300 can rotate relative to the base 200 .

[0063] In some embodiments, when the locking member 110 is formed or connected to the base 200 and the member to be locked 300, the unlocking member 120 is formed or connected to the base 200 and the member to be locked 300, and the locking member 110 located on the member to be locked 300 applies a locking force to the base 200 to keep the base 200 and the member to be locked 300 in the locked position.

[0064] When the unlocking member 120 on the base 200 applies an unlocking force capable of overcoming the locking force to the member to be locked 300 , the member to be locked 300 can rotate relative to the base 200 .

[0065] Through the above technical scheme, the locking member 110 and the unlocking member 120 are used to lock the member 300 to be locked and the base 200 and to rotate the two relative to each other. When the user does not need to use the member 300 to be locked, the member 300 to be locked is maintained in the locked position relative to the base 200, and the member 300 to be locked is prevented from being displaced relative to the base 200. When the member 300 to be locked needs to be rotated relative to the base 200, the unlocking member 120 is used to apply an unlocking force that overcomes the locking force to allow the member 300 to be locked to rotate relative to the base 200, which is convenient for users to use and prevents the member 300 to be locked from shaking or moving slightly on its own during the movement of the vehicle 1, thereby playing the role of fixing the locking member 110. The locking device 100 of the present application has a simple structure and is easy to operate.

[0066] In some embodiments, reference Figure 1 and Figure 2 , the locking member 110 is fixedly connected to the base 200 , and the unlocking member 120 is fixedly connected to the member to be locked 300 .

[0067] Adsorption is used to allow the locking member 110 to apply a locking force to the member to be locked 300 , which can further improve the locking effect, thereby further improving the locking between the base 200 and the member to be locked 300 .

[0068] In some embodiments, the base 200 and the part to be locked 300 have a accommodating space, the locking part 110 is set in the accommodating space of the base 200, the unlocking part 120 is set in the accommodating space of the locking part 110, and the locking part 110 applies a locking force to the part to be locked 300 by adsorbing the unlocking part 120.

[0069] The locking member 110 can be bonded to the accommodation space of the base 200, or connected to the accommodation space of the base 200 by fasteners. Similarly, the unlocking member 120 can be bonded to the accommodation space of the locking member 110, or connected to the accommodation space of the member to be locked 300 by fasteners.

[0070] It should be noted that when the locking member 110 and the unlocking member 120 are arranged in the accommodating space of the base 200 and the member to be locked 300, the adsorption of the locking member 110 and the unlocking member 120 still exists, and parts of the base 200 and the member to be locked 300 are located between the locking member 110 and the unlocking member 120, and the overall appearance is more beautiful.

[0071] Of course, without considering aesthetics, the unlocking member 120 and the locking member 110 can also be set on two opposite sides of the base 200 and the member to be locked 300, and the unlocking member 120 and the locking member 110 can also lock the base 200 and the member to be locked 300.

[0072] In some embodiments, reference Figures 3 to 5 The locking member 110 includes a magnetic portion 111, and the unlocking member 120 includes a contact portion 121. The magnetic portion 111 and the contact portion 121 are adsorbed and connected, thereby achieving adsorption of the locking member 110 and the contact member.

[0073] The contact portion 121 is made of a material with a certain magnetic conductivity, such as iron, nickel, cobalt, steel, magnet, etc., so that the magnetic field portion can adsorb the contact portion 121.

[0074] By utilizing the magnetic field portion of the locking member 110 to adsorb the contact portion 121 , the locking effect can be achieved without too many transmission members and parts, which can effectively reduce product cost and product quality.

[0075] In some examples, the portion of the contact portion 121 facing the magnetic portion 111 is configured as a surface, which can increase the adsorption area between the contact portion 121 and the magnetic portion 111 and ensure the adsorption effect.

[0076] In some embodiments, referring to the figure, the magnetic portion 111 has a first magnetic field, and under the effect of the first magnetic field, the magnetic portion 111 can adsorb the contact portion 121 of the unlocking member 120 .

[0077] The unlocking member 120 further includes a releasing portion 122 , which is connected to the contact portion 121 . The releasing portion 122 has a second magnetic field, and a magnetic field direction of the second magnetic field is opposite to a magnetic field direction of the first magnetic field.

[0078] Since the magnetic field direction of the second magnetic field is opposite to that of the first magnetic field, the release part 122 will repel the magnetic part 111, and the release part 122 is connected to the contact part 121. Therefore, after the release part 122 repel the magnetic part 111, the contact part 121 will be driven to move in a direction away from the magnetic part 111, thereby overcoming the locking force applied by the locking member 110 to the base 200, so that the contact part 121 is separated from the magnetic part 111.

[0079] In some embodiments, the contact portion 121 and the release portion 122 form a movable connection.

[0080] refer to Figure 4 The contact part 121 includes an integrally formed transverse structure and a vertical structure, wherein the transverse structure is the part where the contact part 121 adsorbs the magnetic part 111 , and the vertical structure is the part where the contact part 121 connects the release part 122 . The contact part 121 supports the release part 122 .

[0081] The release portion 122 is provided with an axial hole for movably connecting with the vertical structure, and the axial hole is plugged into the vertical structure to complete the connection between the contact portion 121 and the release portion 122 .

[0082] When the shaft hole retreats backward along the vertical structure, the release portion 122 can be separated from the contact portion 121 .

[0083] refer to Figure 4 The vertical structure is cylindrical and the horizontal structure is disc-shaped, and the two are formed in one piece.

[0084] In some embodiments, at least a portion of the release portion 122 is constructed as an inductor. When the inductor is energized, it generates a second magnetic field opposite to the first magnetic field of the magnetic portion 111, thereby applying an unlocking force to the locking member 110 located on the member to be locked 300.

[0085] In some embodiments, the release portion 122 is constructed as an energized solenoid, which is sleeved on the cylinder of the contact portion 121 .

[0086] In some embodiments, at least a portion of the locking member 110 is constructed as a magnetic body, and the magnetic body and the magnetic portion 111 can be close to and attracted to each other.

[0087] The magnetic body may be a permanent magnet, and the permanent magnet is used to adsorb the magnetic part 111 , which has a simple and convenient structure.

[0088] In some embodiments, the contact portion 121 may also be constructed as a magnetic body, and the two magnetic poles of the two magnetic bodies are in opposite directions to achieve an adsorption effect.

[0089] When the adsorption effect needs to be released, the release unit 122 is energized to generate a magnetic field with a direction opposite to that of the magnetic fields of the two magnetic bodies, thereby separating the two magnetic bodies.

[0090] In some embodiments, the locking device 100 further includes a switch element 130 , which is disposed between the release portion 122 and the power source, and is used to conduct or cut off the electrical connection between the contact portion 121 and the power source.

[0091] The switch element 130 is a common switch in a circuit, and can play the effect of conducting or cutting off the electrical connection between the contact portion 121 and the power source, and its specific structure is not limited.

[0092] The switch member 130 can be connected to the base 200 together with the locking member 110. After the user presses the switch member 130, the unlocking member 120 will be energized, thereby applying an unlocking force to the magnetic part 111 on the locked member 300, so that the contact part 121 is separated from the magnetic part 111, thereby achieving the effect that the locked member 300 can rotate relative to the base 200.

[0093] According to the second aspect of the present application, reference Figure 1, a vehicle-mounted device 10 is provided, comprising a base 200 and a member to be locked 300 which are rotatably connected, and a locking device 100, the locking device 100 is used to lock the base 200 and the member to be locked 300, and the locking device 100 is the locking device 100 as described above.

[0094] The member to be locked 300 fits the base 200 so that the member to be locked 300 is located at a locking position relative to the base 200 .

[0095] The base 200 includes an installation groove, and the locked member 300 is rotatably connected to the base 200 and can be rotated into the installation groove so that the locked member 300 and the base 200 are fitted together. At this time, the locking member 110 can apply a locking force to the unlocking member 120 on the locked member 300, so that the locked member 300 and the base 200 remain in the locked position.

[0096] The base 200 can be connected to the vehicle 1, for example, the vehicle, at the middle roof position of the rear row, and the locking member 300 is constructed as a display screen, and the locking device 100 is used to lock the display screen and the base 200, thereby preventing the display screen from shaking after being stored.

[0097] Alternatively, the base 200 may be connected to the front side of the passenger seat of the vehicle 1 , the member 300 to be locked is configured as a vanity mirror, and the locking device 100 is used to lock the vanity mirror and the base 200 .

[0098] In some embodiments, a locking device 100 may be arranged between the base 200 and the part to be locked 300, or two or more locking devices may be arranged. A locking device 100 may be arranged on one side close to the rotation axis of the part to be locked 300, or a locking device 100 may be arranged on one side of the rotation axis of both the base 200 and the part to be locked 300.

[0099] When the locking member 300 is required to be used, the locking member 300 will rotate relative to the base 200 and rotate a certain angle to a required position.

[0100] In some embodiments, reference Figure 1 and Figure 2 The vehicle-mounted device 10 also includes a flip driving device 400. The driving force for the locked member 300 to rotate relative to the base 200 comes from the flipping force provided by the flip driving device 400. The flip driving device 400 is arranged on the base 200, and the power output shaft of the flip driving device 400 is connected to the locked member 300 to prevent rotation. When the locked member 300 needs to rotate a certain angle, the power output shaft of the flip driving device 400 is used to apply a flipping force to the locked member 300, so that the locked member 300 can rotate relative to the base 200.

[0101] The flipping drive device 400 can use a driving motor, which is arranged on the base 200, and the power output shaft of the flipping drive motor extends into the accommodating groove 20a and is connected to the locking member 300 for rotation prevention. The power output shaft of the flipping drive motor rotates to apply a flipping force to the locking member 300, so that the locking member 300 can rotate relative to the base 200.

[0102] After the member 300 to be locked is rotated relative to the base 200 into the receiving groove 20 a , the member 300 to be locked fits with the bottom of the receiving groove 20 a .

[0103] Alternatively, refer to Figure 6 The flip driving device 400 can also be manually rotated to drive the first mounting bracket connected to the to-be-locked member 300 to rotate, thereby driving the to-be-locked member 300 to rotate relative to the base 200.

[0104] In some embodiments, the vehicle-mounted device 10 further includes an angle measuring device 500, which is disposed on the base 200 and is used to detect a rotation angle reference of the locking member 300 relative to the base 200. Figure 7 The angle measuring device 500 includes an angle measuring sensor 520 and a second mounting bracket 510 , and the second mounting base plate rotates as the locking member 300 rotates.

[0105] The angle measurement sensor 520 measures the rotation angle of the locking member 300 relative to the base 200 .

[0106] According to the third aspect of the present application, reference Figure 8 , a vehicle 1 is provided, which includes the above-mentioned vehicle-mounted device 10. The vehicle 1 has all the beneficial effects of the above-mentioned vehicle-mounted device 10, which will not be repeated in this application.

[0107] The vehicle 1 may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this application does not make any specific limitation on this.
