Specific embodiments

[0048] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0049] The lock core 3, the carding assembly, the vehicle body floor and the vehicle according to embodiments of the present application will be described below with reference to Figs. 1-8.

[0050] The lock core 3 according to embodiments of the present application comprises a first shaft section 31 and a second shaft section 32 connected together. The first shaft section 31 is adapted to be slidingly fitted in the through hole 211 of the carding member 21, which comprises a clamping jaw 212 and a protrusion 213. The clamping jaw 212 forms part of the wall surface of the through hole 211, and the protrusion 213 is arranged on the side of the clamping jaw 212 facing the axis of the through hole 211. The first shaft section 31 can be in sliding contact with the protrusion 213 to facilitate the protrusion 213 and the clamping jaw 212 to move radially outward along the through hole 211, and the protrusion 213 can be resiliently returned to the original position when the second shaft section 32 is radially opposite to the protrusion 213 in the through hole 211.

[0051] According to the lock cylinder 3, the diameter of the first shaft section 31 is greater than the diameter of the second shaft section 32, and the first shaft section 31 is slidingly fitted in the through hole 211 of the clamping piece 21, wherein 0.5d1>d0 is set, when the first shaft section 31 slides relative to the clamping piece 21, the first shaft section 31 can be in sliding contact with the protrusion 213, and then the protrusion 213 and the clamping jaw 212 are moved outward along the radial direction of the through hole 211, at this time, the moving clamping jaw 212 can be clamped into the clamping groove 1111 on the inner wall surface of the clamping hole 111 of the vehicle body floor, so as to realize the clamping of the clamping piece 21 and the clamping hole 111 of the vehicle body floor. When the first shaft section 31 is away from the protrusion 213 and the second shaft section 32 is opposite to the protrusion 213 in the radial direction of the through hole 211, the second shaft section 32 does not interfere with the protrusion 213, and then the protrusion 213 and the clamping jaw 212 can be reset, so that the clamping jaw 212 is separated from the clamping groove 1111, and the clamping piece 21 is separated from the vehicle body floor. That is, only by sliding the lock cylinder 3 in the through hole 211, the installation and disassembly of the clamping piece 21 on the vehicle body floor can be completed, and the clamping piece 21 is convenient to disassemble on the vehicle body floor.

[0052] In some embodiments, as shown in FIG. 8, the diameter of the first shaft section 31 is d1, the diameter of the second shaft section 32 is d2, the minimum distance between the outer surface of the protrusion and the axis of the through hole 211 is d0, and 0.5d1>d0>0.5d2. The lock cylinder 3 further comprises a third shaft section 33 connected to one end of the second shaft section 32 away from the first shaft section 31, and the diameter of the third shaft section 33 is d3, and 0.5d3>d0.

[0053] At this time, when the lock cylinder 3 moves to the second shaft section 32 opposite to the protrusion 213 in the radial direction of the through hole 211, under the interference of the protrusion 213, the first shaft section 31 and the third shaft section 33 of the lock cylinder 3 will not be pulled out of the through hole 211 without external force, thereby effectively avoiding the lock cylinder 3 from being completely separated from the clamping piece 21 to cause the loss of the piece.

[0054] Specifically, the diameter of the first shaft section 31 is equal to the diameter of the third shaft section 33.

[0055] In some embodiments, as shown in FIGS. 6-8, the lock cylinder 3 further comprises a frustum section 34 connected to one end of the first shaft section 31 away from the second shaft section 32, the maximum diameter of the frustum section 34 is equal to the diameter of the first shaft section 31, and the diameter of the frustum section 34 gradually decreases away from the first shaft section 31.

[0056] At this time, the minimum diameter of the frustum segment 34 is smaller than the diameter of the through hole 211, and the insertion operation of the lock cylinder 3 into the through hole 211 is facilitated by the frustum segment 34. Meanwhile, when the first shaft segment 31 moves towards the direction close to the protrusion 213, the outer peripheral surface of the frustum segment 34 first slides with the protrusion 213, and under the transition of the frustum segment 34, the pawl 212 can be more reliably pressed to move radially outward of the through hole 211.

[0057] The clamping assembly according to the embodiments of the present application comprises the clamping piece 21 and the lock cylinder 3 as in the above embodiments, the lock cylinder 3 is movably connected with the clamping piece 21, and the clamping piece 21 can be clamped with the clamping hole 111 on the vehicle body floor when the lock cylinder 3 moves to a set position relative to the clamping piece 21, and the clamping piece 21 can be disengaged from the clamping hole 111 when the lock cylinder 3 moves to other positions relative to the clamping piece 21.

[0058] According to the clamping assembly of the embodiments of the present application, the installation and disassembly of the clamping piece 21 on the vehicle body floor can be completed by moving the lock cylinder 3 relative to the clamping piece 21, and the disassembly of the clamping piece 21 on the vehicle body floor is facilitated.

[0059] In some embodiments, as shown in FIGS. 6 and 7, the wall surface of the clamping hole 111 is provided with a clamping groove 1111. The clamping piece 21 is fitted in the clamping hole 111 and has an initial position and a pressed position, the clamping piece 21 is slidable relative to the clamping hole 111 in the initial position, and at least part of the clamping piece 21 is fitted in the clamping groove 1111 in the pressed position. When the clamping piece 21 is in the pressed position, the lock cylinder 3 can prevent the clamping piece 21 from resetting to the initial position.

[0060] That is, the clamping piece 21 is connected with the lock cylinder 3 to make at least part of the clamping piece 21 fit in the clamping groove 1111, so as to realize the clamping of the clamping piece 21 with the corresponding clamping hole 111. When it is necessary to dismount the clamping piece 21, the lock cylinder 3 is only needed to be dismounted from the clamping piece 21, so that the lock cylinder 3 releases the compression on at least part of the clamping piece 21, and at least part of the clamping piece 21 is disengaged from the clamping groove 1111, so as to facilitate the clamping piece 21 to be disengaged from the clamping hole 111 as a whole, and the disassembly of the functional module 2 where the clamping piece 21 is located is rapid, and the user experience is high.

[0061] Specifically, as shown in FIG. 2, the first mounting hole 11 and the second mounting hole 12 each comprise two clamping holes 111, and the functional module 2 comprises two clamping pieces 21, and the two clamping pieces 21 are clamped with the two clamping holes 111 respectively.

[0062] In some embodiments, as shown in FIGS. 3-8, the clamping hole 111 penetrates the plate body 1 of the vehicle body floor in a first direction, the clamping piece 21 has a through hole 211 penetrating the clamping piece 21 in the first direction, the clamping piece 21 includes at least two clamping claws 212, the at least two clamping claws 212 are arranged at intervals along the circumference of the through hole 211 and form part of the wall surface of the through hole 211, the clamping claws 212 have an initial position and a pressed position, and the clamping claws 212 are fitted in the clamping groove 1111 in the pressed position. The lock core 3 is slidably fitted in the through hole 211, and at least part of the lock core 3 is clamped between the at least two clamping claws 212 when the clamping claws 212 are in the pressed position.

[0063] That is, when the at least two clamping claws 212 of the clamping piece 21 are fitted in the clamping hole 111, the clamping piece 21 is clamped in the clamping hole 111 by inserting the lock core 3 into the through hole 211 and pressing the clamping claws 212 to deform the clamping claws 212 at least partially and press the clamping claws 212 into the clamping groove 1111, thereby achieving the clamping of the clamping claws 212 and the clamping hole 111. At this time, when it is necessary to remove the clamping piece 21, the lock core 3 is only needed to be moved so that the lock core 3 releases the pressure on the clamping claws 212, and the clamping claws 212 will rebound to the initial position, and the clamping claws 212 can be directly pulled out of the clamping hole 111, so that the disassembly of the functional module 2 where the clamping piece 21 is located is rapid, and the user experience is high.

[0064] Specifically, the clamping claws 212 can be two, three or four. When the clamping claws 212 are four, the four clamping claws 212 are arranged at equal intervals along the circumference of the through hole 211. The opening of the clamping groove 1111 is formed on the bottom surface of the plate body 1, the clamping groove 1111 is a ring-shaped groove 311, and the bottom surface of the clamping groove 1111 is a limiting surface for preventing the clamping claws 212 from being pulled out of the clamping groove 1111. When the clamping claws 212 are clamped with the clamping hole 111, the part of the functional module 2 where the clamping piece 21 is located is in abutment with the top surface of the plate body 1.

[0065] In some embodiments, as shown in FIG. 7, the lock core 3 has a clamping position and an unlocking position, and the lock core 3 can drive the clamping claws 212 to move outward in the radial direction of the through hole 211 when the lock core 3 is moved from the unlocking position to the clamping position, and the clamping claws 212 are fitted in the clamping groove 1111 when the lock core 3 is in the clamping position.

[0066] That is, when the lock core 3 slides in the axial direction of the through hole 211 from the unlocking position to the clamping position, the lock core 3 and the clamping claws 212 slide relative to each other, the clamping claws 212 are deformed outward in the radial direction of the through hole 211 under the pressure of the lock core 3, and part of the clamping claws 212 are fitted in the clamping groove 1111 when the lock core 3 is in the clamping position, so as to complete the clamping of the clamping claws 212 and the clamping hole 111. That is, the clamping and unlocking of the clamping piece 21 and the clamping hole 111 can be achieved only by sliding the lock core 3 in the through hole 211, and the disassembly of the functional module 2 on the plate body 1 is convenient.

[0067] In some embodiments, as shown in FIGS. 6-8, each claw 212 is provided with a protrusion 213 on one side of the axis of the through hole 211, the protrusion 213 is located in the through hole 211 when the claw 212 is in the initial position, and the lock core 3 comprises a first shaft section 31 which is slidingly fitted in the through hole 211. When the lock core 3 is in the clamping position, the first shaft section 31 is clamped between the at least two protrusions 213, and the claw 212 is in the pressed position. When the lock core 3 is in the unlocking position, the claw 212 is in the initial position.

[0068] When the first shaft section 31 slides in the through hole 211 to the unlocking position, the first shaft section 31 is arranged in the first direction with the protrusions 213 and the claws 212, and the claws 212 remain in the initial position. When the first shaft section 31 moves from the unlocking position to the clamping position, the first shaft section 31 slidingly fits with the protrusions 213, and the first shaft section 31 pushes the protrusions 213 to move outward along the radial direction of the through hole 211 until the first shaft section 31 moves to the clamping position, and the part of the claw 212 connected with the protrusion 213 extends into the clamping groove 111 under the pressure of the protrusion 213, thereby completing the clamping of the claw 212 with the clamping hole 111 and the installation of the functional module 2 on the plate body 1. At this time, the functional module 2 can be detached only by moving the first shaft section 31 to the unlocking position in the opposite direction.

[0069] In some embodiments, as shown in FIGS. 6 and 7, the peripheral surface of the first shaft section 31 is provided with an annular groove 311, and at least part of the at least two protrusions 213 fits in the annular groove 311 when the lock core 3 is in the clamping position.

[0070] The cooperation of at least part of the protrusions 213 with the annular groove 311 makes the force required for the first shaft section 31 to move from the clamping position to the unlocking position greater, thereby effectively avoiding the functional module 2 from being mistakenly detached from the plate body 1 due to the mistaken switching of the first shaft section 31 to the unlocking position, and improving the installation reliability of the functional module 2 on the plate body 1.

[0071] In some embodiments, as shown in FIG. 8, the outer peripheral surface of the lock core 3 is provided with an avoiding groove 321 which is engaged with the first shaft section 31, and the protrusion 213 can fit in the avoiding groove 321 to facilitate the resetting of the claw 212 to the initial position.

[0072] That is, when the lock core 3 slides to the position where the avoiding groove 321 is opposite to the protrusion 213, the protrusion 213 fits in the avoiding groove 321, and the claw 212 rebounds to the initial position. At this time, the claw 212 can be directly pulled out of the clamping hole 111, thereby achieving the disassembly of the functional module 2.

[0073] In some embodiments, as shown in FIG. 8, the lock core 3 further comprises a second shaft segment 32 and a third shaft segment 33 connected in sequence, the second shaft segment 32 is connected to the first shaft segment 31 at an end away from the third shaft segment 33, the third shaft segment 33 has a diameter larger than that of the second shaft segment 32 and equal to that of the first shaft segment 31, the end surface of the first shaft segment 31 facing the third shaft segment 33, the end surface of the third shaft segment 33 facing the first shaft segment 31 and the outer peripheral surface of the second shaft segment 32 jointly define an avoiding groove 321.

[0074] That is, when the first shaft segment 31 is in the unlocking position, the protrusion 213 is located in the avoiding groove 321 between the first shaft segment 31 and the third shaft segment 33, and under the limiting of the first shaft segment 31 and the third shaft segment 33, the lock core 3 will not be separated from the through hole 211 when the functional module 2 is detached, thereby effectively reducing the risk of losing the lock core 3.

[0075] In some embodiments, as shown in FIG. 6, the lock core 3 further comprises a frustum segment 34 connected to the first shaft segment 31 at an end away from the avoiding groove 321, the frustum segment 34 has a maximum diameter equal to that of the first shaft segment 31, and the diameter of the frustum segment 34 gradually decreases in a direction away from the first shaft segment 31, the outer peripheral surface of the frustum segment 34 is in sliding fit with the protrusion 213 to facilitate the movement of the pawl 212 between the initial position and the stressed position.

[0076] At this time, the minimum diameter of the frustum segment 34 is smaller than the diameter of the through hole 211, and the insertion of the lock core 3 into the through hole 211 is facilitated. Meanwhile, when the first shaft segment 31 moves towards the clamping position, the outer peripheral surface of the frustum segment 34 is more easily in sliding fit with the protrusion 213, so as to more reliably achieve the compression of the pawl 212 towards the stressed position.

[0077] As shown in FIG. 8, when the pawl 212 is in the initial position, the protrusion 213 has a first guide inclined surface 2131 and a second guide inclined surface 2132 opposite along the axial direction of the through hole 211, and the first shaft segment 31 is in sliding fit with any one of the first guide inclined surface 2131 and the second guide inclined surface 2132 to facilitate the movement of the pawl 212 between the initial position and the stressed position. Thus, it is ensured that the first shaft segment 31 moves between the clamping position and the unlocking position, and the switching of the pawl 212 between the initial position and the stressed position is more reliably achieved.

[0078] In some embodiments, as shown in FIG. 4, the clamping piece 21 further comprises a substrate 214 having a first surface 2141 and a second surface 2142 opposite to each other in the first direction, the through hole 211 penetrates the substrate 214, and the clamping jaw 212 is arranged on the first surface 2141 of the substrate 214. The substrate 214 is connected with the body 22 of the functional module 2, the body 22 has a third surface 221 opposite to the second surface 2142 in the first direction and spaced apart from the second surface 2142, and the third surface 221 and the second surface 2142 form a relief space 222 for inserting the lock cylinder 3 into the through hole 211.

[0079] The design of the relief space 222 facilitates the user to insert the lock cylinder 3 into the through hole 211 from the second surface 2142. Meanwhile, the design of the third surface 221 also avoids the direct exposure of the through hole 211 to the outside, thereby effectively avoiding the mistaken touch of the lock cylinder 3 in the through hole 211 to cause the clamping jaw 212 to release the clamping with the clamping hole 111, and further ensuring the installation reliability of the functional module 2 on the panel body 1.

Moreover, when the auxiliary instrument panel is not used, the auxiliary instrument panel can be detached from the panel body 1, and the first mounting hole 11 and the second mounting hole 12 vacated will not occupy the vehicle interior space, and can be connected with other functional modules 2, so that the utilization rate of the vehicle interior space is high.

[0082] It should be noted that the number of the first mounting hole 11 and the second mounting hole 12 is not limited in the embodiment, and can be one or more. In addition, the above-mentioned multiple scene use requirements refer to the different positions of the auxiliary instrument panel installed on the panel body 1, which can play different functions to adapt to different scene requirements.

[0083] In addition, after the user detaches the auxiliary instrument panel, other functional modules 2 such as table plates, refrigerators, etc. can be installed at the first mounting hole 11 and the second mounting hole 12.

In other words, on the basis that the number of clamping holes 111 is certain, the total number of the first mounting hole 11 and the second mounting hole 12 is more, and the space utilization rate in the vehicle body is higher.

[0086] Alternatively, any clamping hole 111 in the first mounting hole 11 and any clamping hole 111 in the second mounting hole 12 are arranged at intervals. That is, the first mounting hole 11 and the second mounting hole 12 are independently provided and do not share the clamping hole 111, the independence of the first mounting hole 11 and the second mounting hole 12 is stronger, and the first mounting hole 11 and the second mounting hole 12 can be respectively processed and formed and respectively connected with different sub-instrument panels, and the processing difficulty of the first mounting hole 11 and the second mounting hole 12 is lower.
