Furthermore, terms as defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense unless expressly defined in this specification.

[0016] 1 to 4, a side impact protection block 100 according to an embodiment of the present disclosure and a mounting base 5 cooperating with the side impact protection block 100 are shown in schematic form. Referring to FIG. 32, the side impact protection block 100 and the mounting base 5 are configured to be mounted on a side wing 91 of a child safety seat 9. The child safety seat 9 is mounted in a vehicle, such as an automobile. In the following description, the child safety seat 9 mounted in the vehicle is taken as an example. During sudden braking of the vehicle or an accidental collision, the side impact protection block 100 comes into contact with the inner side wall of the vehicle, thereby suppressing and cushioning the lateral movement of the child safety seat 9, thereby enhancing the protection of a child or infant riding in the child safety seat 9. Referring to FIG. 33, the mounting base 5 is fixedly disposed on the side wing 91 of the child safety seat 9, and the side impact protection block 100 is detachably attached to the mounting base 5.

[0017] The side impact protection block 100 includes a housing 1, a button 2, and a locking member 3, and the number of the button 2 and the locking member 3 is not limited to one. The housing 1 includes an upper wall 11, a side wall 12 connected to the upper wall 11, and a bottom wall 13 connected to the side wall 12. The upper wall 11 includes a side impact contact surface 110, which is configured to impact the inner side wall of the vehicle when the child safety seat 9 tends to move laterally, thereby limiting the lateral movement of the child safety seat 9. It should be understood that since the child safety seat 9 is usually mounted on the side of the rear seat of the vehicle, only the side impact protection block 100 on one side of the child safety seat 9 plays a role in preventing lateral movement. The side impact protection block 100 is detachably connected to the mounting base 5, so that two mounting bases 5 are provided on both side wings 91 of the child safety seat 9, and the side impact protection block 100 is mounted on the mounting base 5 on either side of the child safety seat 9 as required. In the illustrated embodiment, side impact contact surface 110 is a relatively smooth, arcuate surface, however, in other embodiments, the shape of side impact contact surface 110 is planar as long as it serves to contact the inside of the vehicle to prevent lateral movement.

[0018] Referring to FIG. 1, a button 2 is disposed on a side wall 12 of a housing 1. A locking member 3 is disposed on the side wall 12 of the housing 1 and includes a locking portion. The button 2 is pressed by a pressing force and is operably connected to the locking member 3, and the locking member 3 has a locked state and an unlocked state. An operable connection in the present disclosure includes, but is not limited to, a direct connection, an indirect connection, a fixed connection, a pivot connection, an abutting contact, and the like. Two components being operably connected means that the operation of one component causes the operation of the other component.

[0019] 2 to 4, in this embodiment, the locking member 3 includes a first elastic arm 31 integrally formed with the side wall 12. A first end 3101 of the first elastic arm 31 adjacent to the top wall 11 is a connected end, and a second end 3102 of the first elastic arm 31 adjacent to the bottom wall 13 is a free end. The locking part includes a first hook 3a1 disposed at the free end. The button 2 is disposed at a middle portion of the first elastic arm 31. For example, the button 2 is integrally formed with the first elastic arm 31, or the button 2 is attached to a middle portion of the first elastic arm 31. In this way, when no pressing force is applied, the button 2 is in an initial position, and the first hook 3a1 of the first elastic arm 31 is in a locked state. When the button 2 is pressed by a pressing force and moves from the initial position to the pressed position, the first elastic arm 31 is elastically deformed and driven by the button 2, and the first hook 3a1 moves toward the interior 10 of the housing 1, switching from the locked state to the unlocked state. When the pressing force is removed, the first elastic arm 31 elastically restores its original state, the button 2 elastically returns to the initial position, and the first hook 3a1 elastically returns to the locked state.

[0020] 3 and 4, the mounting base 5 is formed with a mounting groove 50 configured to partially accommodate the housing 1 of the side impact protection block 100. It should be understood that at least a portion of the bottom wall 13 and the side wall 12 of the housing 1 are accommodated in the mounting groove 50. The side wall 501 of the mounting groove 50 is provided with a locking hole 5011, which is configured to receive the locking portion of the locking member 3. More specifically, in this embodiment, the locking hole 5011 is configured to receive the first hook 3a1 of the first elastic arm 31.

[0021] 2, when the side impact protection block 100 needs to be attached to the mounting base 5, the button 2 is pressed to elastically deform the first elastic arm 31 and switch the first hook 3a1 to the unlocked state. The side impact protection block 100 is then inserted into the mounting groove 50 in the direction indicated by the arrow P, and the first hook 3a1 also enters the mounting groove 50. It should be understood that the first hook 3a1 has a wedge-shaped surface, allowing the side impact protection block 100 to be inserted into the mounting groove 50 without the button 2 being actively pressed.

[0022] 4, when the side impact protection block 100 is inserted into a predetermined position, the pressing force on the button 2 is removed, the first elastic arm 31 elastically restores its original position, the first hook 3a1 is switched to a locked state and locked into the locking hole 5011 provided in the side wall 501 of the mounting groove 50, and the button 2 elastically returns to its initial position, preventing the side impact protection block 100 from accidentally falling off from the mounting groove 50. When it is necessary to remove the side impact protection block 100 from the mounting groove 50, a pressing force is applied to the button 2 to elastically deform the first elastic arm 31 again, disengaging the first hook 3a1 from the locking hole 5011, allowing the side impact protection block 100 to be freely removed from the mounting groove 50.

[0023] The side impact protection block 100 has a simple structure, is low cost, and is easy to attach to and detach from the mounting base 5. Therefore, a consumer may optionally provide one or more side impact protection blocks 100 on the child safety seat 9 so that they can be replaced as needed.

[0024] 2 to 4, in some embodiments, the housing 1 includes a first housing part 101 and a second housing part 102. The first housing part 101 is a hollow structure having an opening at its bottom. The top wall 1011 of the first housing part 101 forms the top wall 11 of the housing 1, and the side impact contact surface 110 is located on the top wall 1011 of the first housing part 101. The side wall 1012 of the first housing part 101 forms the side wall 12 of the housing 1. The first elastic arm 31 is integrally formed with the side wall 1012 of the first housing part 101. The second housing part 102 is assembled to the bottom opening of the first housing part 101. The bottom wall 1023 of the second housing part 102 seals the bottom opening of the first housing part 101 and forms the bottom wall 13 of the housing 1. The second housing part 102 further includes a first rib plate set 1021 extending from a bottom wall 1023 of the second housing part 102 into the first housing part 101, and the first rib plate set 1021 has the effect of reinforcing the structural strength of the first housing part 101. The first rib plate set 1021 includes a first limiting plate 10211 corresponding to the first elastic arm 31, and the first limiting plate 10211 effectively prevents the first elastic arm 31 from being damaged due to excessive pressure.

[0025] In another embodiment, the housing 1 does not include the second housing part 102. In this case, the bottom wall of the first housing part 101 forms the bottom wall 13 of the housing 1, and the bottom wall of the first housing part 101 is openable and closable.

[0026] 1 to 4, in some embodiments, the mounting base 5 includes an end cap 51. When the side impact protection block 100 is not attached to the mounting groove 50, the end cap 51 is configured to block the opening of the mounting groove 50, and the end cap 51 is supported at the opening of the mounting groove 50 by, for example, at least one fourth elastic member 53 in the mounting groove 50. When the side impact protection block 100 is attached to the mounting groove 50, the end cap 51 receives a pressing force from the bottom wall 13 of the housing 1 and compresses the fourth elastic member 53. When the end cap 51 moves toward the bottom 502 of the mounting groove 50, the locking hole 5011 of the side wall 501 of the mounting groove 50 is exposed and locked with the locking portion of the locking member 3 of the side impact protection block 100 (more specifically, the first hook 3a1 of the first elastic arm 31).

[0027] 3, in some embodiments, the end cap 51 includes one or more third elastic arms 511. The third elastic arms 511 include hooks 511a. The side wall 501 of the mounting groove 50 is provided with one or more second slide holes 5012. The hooks 511a engage with the lock ends 5012a of the second slide holes 5012 to fix the end cap 51 in a position that blocks the opening of the mounting groove 50. When the end cap 51 is subjected to a pressing force, the hooks 511a move along the second slide holes 5012, and the side impact protection block 100 is inserted into the mounting groove 50, exposing the lock holes 5011 to cooperate with the locking portions of the locking members 3.

[0028] In some embodiments, the fourth resilient member 53 includes two spaced apart springs to provide sufficient support for end caps 51 having a larger area. In other embodiments, the fourth resilient member 53 includes one spring or multiple springs.

[0029] In some embodiments, the locking hole 5011 is aligned with the locking end 5012a of the second slide hole 5012, which is beneficial to simplify the manufacturing process.

[0030] 5 to 10, which are schematic diagrams illustrating a side impact protection block 100 and a mounting base 5 cooperating with the side impact protection block 100 according to another embodiment of the present disclosure. The main difference between this embodiment and the previous embodiment lies in the structure of the side impact protection block 100. The structures of the mounting bases 5 are similar to each other, so the details will not be repeated here.

[0031] 5 and 6, similar to the previous embodiment, the housing 1 includes a top wall 11, a side wall 12, and a bottom wall 13. The top wall 11 includes a side impact contact surface 110. The button 2 is disposed on the side wall 12 of the housing 1 and is switchable between an initial position and a pressed position. The locking member 3 is disposed within the housing 1 and includes a locking portion. The button 2 is operably connected to the locking member 3 such that the locking portion of the locking member 3 can be switched between a locked state and an unlocked state.

[0032] Referring to FIG. 7, the housing 1 includes a third housing part 103 and a fourth housing part 104. The third housing part 103 is a hollow structure having an opening at the bottom. The top wall 1031 of the third housing part 103 forms the top wall 11 of the housing 1, the side impact contact surface 110 is located on the top wall 1031 of the third housing part 103, and the side wall 1032 of the third housing part 103 forms the side wall 12 of the housing 1. The fourth housing part 104 is assembled to the bottom opening of the third housing part 103. The bottom wall 1043 of the fourth housing part 104 closes the bottom opening of the third housing part 103 and forms the bottom wall 13 of the housing 1. The fourth housing portion 104 further includes a second set of rib plates 1042 extending from a bottom wall 1043 of the fourth housing portion 104 into the interior of the third housing portion 103, the second set of rib plates 1042 having the effect of reinforcing the structural strength of the third housing portion 103.

[0033] 5, 7 and 8, the button 2 is disposed in a button hole 120 provided in a side wall 1032 of the third housing portion 103, and at least a portion of the hole wall of the button hole 120 is formed by the side wall 1032. The button 2 includes an outer end 21 configured to withstand a pressing force and an inner end 22 located in the interior 10 of the housing 1. In some embodiments, the side wall 1032 includes a first hole segment 120a configured to slidably fit with the button 2, and the second rib plate set 1042 includes an annular extension plate 10421 that defines a second hole segment 120b that slidably fits with the button 2, and the first hole segment 120a communicates with the second hole segment 120b to form the button hole 120. In some other embodiments, the annular extension plate 10421 is not disposed on the second set of rib plates 1042 but is integrally formed with the side wall 1032 .

[0034] 9 and 10, two locking members 3 are disposed inside 10 of housing 1, and the two locking members 3 are disposed substantially symmetrically inside 10 of housing 1 and operably connected to the same button 2. A first end 301a of the locking member 3 is in contact with the inner end 22 of the button 2. An abutment surface for abutting the first end 301a of the inner end 22 of the button 2 is an inclined surface 220, and the inclined surface 220 faces the upper wall 1031 of the third housing part 103. An intermediate part of each locking member 3 is pivotally connected to the housing 1 via a first pin shaft 391. The first pin shaft 391 is attached, for example, to a hole 10420 (see FIG. 7) of the second rib plate set 1042. The locking part includes a second hook 3a2 located at the second end 302a of the locking member 3, and the second hook 3a2 is bent toward the side wall 12.

[0035] In some embodiments, the locking member 3 is substantially L-shaped and includes a first arm 301, a corner portion 303, and a second arm 302, which are connected in sequence. The free end of the first arm 301 forms a first end portion 301a of the locking member 3, and a first pin shaft 391 is disposed on the corner portion 303. The free end of the second arm 302 forms a second end portion 302a of the locking member 3. The locking member 3 of this configuration has a smaller volume and a more streamlined structure.

[0036] The side wall 1032 of the third housing part 103 includes a first through hole 1201 that allows the second hook 3a2 to extend therethrough. A first elastic member 41 is further disposed in the interior 10 of the housing 1. Referring to Figs. 8 and 9, when the button 2 is in the initial position, the tip region of the inclined surface 220 abuts against the first end 301a of the locking member 3, and the first elastic member 41 acts on the locking member 3 to maintain the second hook 3a2 in a locked state in which it extends from the first through hole 1201. In this case, the second hook 3a2 is locked in the locking hole 5011 of the mounting base 5, and the side impact protection block 100 does not come out of the mounting groove 50. 8 and 10, when the outer end 21 of the button 2 receives a pressing force, the button 2 is switched from the initial position to the pressed position, and the inclined surface 220 of the button 2 presses the first arm 301, causing the locking member 3 to pivot about the first pin shaft 391 and overcome the biasing force of the first elastic member 41, and the second hook 3a2 is switched to an unlocked state in which it is retracted from the first through-hole 1201. At this time, the side impact protection block 100 can be easily removed from the mounting groove 50.

[0037] It should be understood that when the side impact protection block 100 needs to be inserted into the mounting groove 50, the button 2 is pressed to put the second hook 3a2 of the locking member 3 into an unlocked state, and then the side impact protection block 100 is inserted into the mounting groove 50 in the direction shown by arrow P in Figure 6. When the pressing force is released, the second hook 3a2 is locked in the locking hole 5011. Because the second hook 3a2 has a wedge-shaped surface, the side impact protection block 100 can also be inserted into the mounting groove 50 without actively pressing the button 2.

[0038] 7, 9, and 10, in some embodiments, the first elastic member 41 includes a reset strip connected to the second arm 302 of the locking member 3, and a limiting wall 10422 in contact with the reset strip is disposed in the interior 10 of the housing 1. When the button 2 is pressed to the pressed position, the locking member 3 is pivoted by the action of the inclined surface 220, and not only is the second hook 3a2 switched from the locked state to the unlocked state, but the reset strip is also elastically deformed. When the button 2 elastically returns to the initial position, the reset strip automatically elastically restores while driving the locking member 3 to pivot about the first pin shaft 391, and the second hook 3a2 elastically returns to the locked state and maintains the locked state.

[0039] In some embodiments, a free end of the reset piece is in contact with the limiting wall 10422, and the other end of the reset piece opposite the free end extends to the locking member 3. That is, the reset piece and the corresponding locking member 3 are integrally formed. The limiting wall 10422 is formed by a wall of a portion of a rib plate of the second rib plate set 1042.

[0040] The movement direction of the button 2 is substantially parallel to the extension direction of the first pin shaft 391, which is convenient for manufacturing. In this embodiment, the inclined surface 220 is formed on the inner end 22 of the button 2 to bias each locking member 3 to rotate, but in another embodiment, the inclined surface is disposed on the first end 301a of the locking member 3, or on both the inner end 22 of the button 2 and the first end 301a of the locking member 3. Therefore, when the button 2 is pressed from the initial position to the pressed position, the inner end 22 of the button 2 and the first end 301a of the locking member 3 rotate the locking member 3 through contact of the inclined surface, and the second hook 3a2 is switched from the locked position to the unlocked position.

[0041] In this embodiment, the first elastic member 41 is described as a reset piece, but in another embodiment, the first elastic member 41 also includes other implementations. For example, the first elastic member 41 is a spring disposed between the second arm 302 and the limiting wall 10422, or a torsion disposed between the first pin shaft 391 and the locking member 3.

[0042] In some embodiments, a first movement limiting structure 201 is disposed between the button 2 and the housing 1, and the first movement limiting structure 201 is configured to limit the stroke of the button 2 between an initial position and a pressed position, and also prevents the button 2 from being dislodged from the button hole 120. There are many embodiments of the first movement limiting structure 201. For example, referring to FIG. 7 and FIG. 8, the first movement limiting structure 201 includes a limiting hole 2010 and a second elastic arm 2012. The limiting hole 2010 is formed in the hole wall of the button hole 120, for example, in the annular extension plate 10421 (the second hole segment 120b of the button hole 120 is defined by the annular extension plate 10421). The second elastic arm 2012 is integral with the button 2. A first end 2012a of the second elastic arm 2012 adjacent to the outer end 21 of the button 2 is a connected end, and a second end 2012b of the second elastic arm 2012 adjacent to the inner end 22 of the button 2 is a free end. The second end 2012b of the second elastic arm 2012 includes a boss 20121 that slidably cooperates with the limiting hole 2010, and the end of the limiting hole 2010 limits the sliding position of the boss 20121, thereby limiting the stroke of the button 2.

[0043] 8, in some embodiments, the second elastic member 42 is disposed between the button 2 and the housing 1 to maintain the button 2 in the initial position. The second elastic member 42 allows the button 2 to elastically return to the initial position from the pressed position. It should be understood that in some embodiments, the second elastic member 42 is omitted. When the lock member 3 pivots about the first pin shaft 391 due to the elastic recovery action of the first elastic member 41, the first arm 301 presses the inclined surface 220 to push the button 2 to the initial position of the elastic return.

[0044] The second elastic member 42 is a spring. In some embodiments, a groove 20 is disposed in the middle portion of the button 2 and configured to accommodate the second elastic member 42, and an outer end 20a of the groove 20 limits the outer end of the second elastic member 42. A protrusion 1200 configured to abut against an inner end of the second elastic member 42 is provided on the hole wall of the button hole 120. It should be understood that the protrusion 1200 does not affect the movement of the button 2 between the initial position and the pressed position. In this way, when the button 2 is pressed to the pressed position, the second elastic member 42 is compressed between the outer end 20a of the groove 20 and the protrusion 1200 (the wall of the groove 20 includes an opening for the protrusion 1200 to protrude into the groove 20). When the pressing force applied to the button 2 is removed, the second elastic member 42 automatically elastically restores and drives the button 2 to elastically return to the initial position. In some embodiments, the protruding portion 1200 further includes a protruding post 1200a, and an inner end of the second resilient member 42 is sleeved onto the protruding post 1200a.

[0045] In this embodiment, two locking members 3 are operably connected to the same button 2, however, in another embodiment, one button 2 is configured to be operably connected to one locking member 3.

[0046] 11 to 19, there is shown a schematic diagram of a side impact protection block 100 and a mounting base 5 cooperating with the side impact protection block 100 according to another embodiment of the present disclosure. This embodiment is similar to the previous embodiment, but has slightly different structures of the housing 1, the button 2, the locking member 3, and the mounting base 5. For the structures and connection relationships of the components in this embodiment, please refer to the descriptions in the previous embodiment to the extent that no contradiction occurs.

[0047] 13 and 14, in this embodiment, the housing 1 similarly includes a third housing part 103 and a fourth housing part 104. The third housing part 103 is hollow and has an opening at its bottom. The top wall 1031 of the third housing part 103 forms the top wall 11 of the housing 1, the side impact contact surface 110 is located on the top wall 1031 of the third housing part 103, and the side wall 1032 of the third housing part 103 forms the outer side wall of the housing 1. The fourth housing part 104 is assembled to the bottom opening of the third housing part 103. The bottom wall 1043 of the fourth housing part 104 covers the bottom opening of the third housing part 103 and forms the bottom wall 13 of the housing 1.

[0048] 17, the fourth housing part 104 further includes a recess 10430 extending from a middle portion of the bottom wall 1043 toward the top wall 1031 of the third housing part 103 such that the bottom wall 1043 has a generally annular shape. The recess 10430 includes the top wall 10431 and a side wall 10432, which forms an inner side wall of the housing 1. It should be understood that in this embodiment, the side wall 12 of the housing 1 includes the side wall 1032 of the third housing part 103 and the side wall 10432 of the recess 10430. Referring to FIG. 13, the fourth housing part 104 further includes a second set of rib plates 1042 extending from the bottom wall 1043 to the inside of the third housing part 103, which is configured to reinforce the structural strength of the third housing part 103. The recesses 10430 are connected to a second set of rib plates 1042 on a surface of the interior 10 of the housing 1 .

[0049] 14, the button 2 is slidably received in the buttonhole 120. The buttonhole 120 includes a first hole segment 120a defined in the sidewall 1032 and a second hole segment 120b defined by an annular extension plate 10421 of the second rib plate set 1042. The first hole segment 120a communicates with the second hole segment 120b to form the buttonhole 120. An outer end 21 of the button 2 is configured to withstand a pressing force. An inner end 22 of the button 2 extends into the interior 10 of the housing 1 defined by the third housing portion 103 and the fourth housing portion 104.

[0050] 15 and 16, two locking members 3 are disposed inside 10 of housing 1, and the two locking members 3 are disposed substantially symmetrically inside 10 of housing 1 and operably connected to the same button 2. Each locking member 3 includes a first arm 301, a corner portion 303, and a second arm 302 connected in sequence. A free end of the first arm 301, which is a first end portion 301a of the locking member 3, contacts an inner end 22 of the button 2. A contact surface of the inner end 22 of the button 2 for contacting with the free end 301a of the first arm 301 is an inclined surface 220, and the inclined surface 220 faces in a direction away from the upper wall 1031 of the third housing part 103. The corner portion 303 is located in a middle portion of the locking member 3 and is pivotally connected to the housing 1 via a first pin shaft 391. The first pin shaft 391 is attached, for example, to a hole 10420 (see FIG. 13) of the second rib plate set 1042. The locking portion includes a second hook 3a2 located at the free end of the second arm 302 (i.e., the second end 302a of the locking member 3), the second hook 3a2 being bent towards the side wall 10432.

[0051] The first through hole 1201 is formed in a side wall 10432 of the recess 10430. A first elastic member 41 is further disposed in the interior 10 of the housing 1, and the first elastic member 41 is a reset piece integrally formed with the first arm 301 of the locking member 3. One end of the reset piece is connected to, for example, the free end 301a of the first arm 301, and the other end of the reset piece is in contact with, for example, a limiting wall 10422 of the interior 10 of the housing 1. The limiting wall 10422 is formed by a partial wall of a rib plate of the second rib plate set 1042 or a partial surface of the recess 10430 of the interior 10 of the housing 1. The first elastic member 41 is configured to act on the locking member 3 to maintain the second hook 3a2 in a locked state extended from the first through hole 1201.

[0052] 12, 18 and 19, in this embodiment, a protrusion 55 for insertion into the recess 10430 of the fourth housing part 104 is disposed in the mounting groove 50 of the mounting base 5, and the protrusion 55 has a hollow structure. The side wall 501 of the mounting groove 50 includes an outer peripheral side wall 501a and an inner peripheral side wall 501b, and a lock hole 5011 for engaging with the second hook 3a2 of the locking member 3 is provided in the inner peripheral side wall 501b. The opening of the mounting groove 50 is annular, and an annular end cap 51 is disposed in the mounting groove 50. As in the above-described embodiment, the end cap 51 is supported at the open end of the mounting groove 50 by the fourth elastic member 53, and when a pressing force is applied, the end cap 51 moves to the bottom of the mounting groove 50 to expose the lock hole 5011. FIG. 19 is a schematic perspective view of the end cap 51 pressed against the bottom of the mounting groove 50. Similar to the previous embodiment, the end cap 51 includes a third resilient arm having a hook. For example, the hook of the third resilient arm is slidably received in the second slide hole 5012 in the inner peripheral side wall 501b. Furthermore, the lock end 5012a of the at least one second slide hole 5012 is aligned with the at least one lock hole 5011.

[0053] 14 and 15, when the button 2 is in the initial position, the tip region of the inclined surface 220 abuts against the first end 301a of the locking member 3, and the first elastic member 41 acts on the locking member 3 to maintain the second hook 3a2 in a locked state in which it extends from the first through-hole 1201. In this case, the second hook 3a2 is engaged with the locking hole 5011 of the mounting base 5, and the side impact protection block 100 does not come off from the mounting groove 50. Referring to FIG. 14 and FIG. 16, when the outer end 21 of the button 2 is switched from the initial position to the pressed position by receiving a pressing force, the inclined surface 220 of the button 2 presses the first arm 301, so that the locking member 3 pivots about the first pin shaft 391 against the biasing force of the first elastic member 41, and the second hook 3a2 is switched to an unlocked state in which it retreats from the first through-hole 1201. At this time, the side impact protection block 100 can be easily removed from the mounting groove 50. When it is necessary to insert the side impact protection block 100 back into the mounting groove 50 of the mounting base 5, insert the side impact protection block 100 into the mounting groove 50 along the direction of arrow P shown in FIG.

[0054] Similar to the previous embodiment, the movement direction of the button 2 is substantially parallel to the extension direction of the first pin shaft 391. Between the button 2 and the housing 1, a first movement limiting structure 201 is provided (see FIG. 7), which is configured to limit the stroke of the button 2 between the initial position and the pressed position and to prevent the button 2 from falling off the button hole 120. Between the button 2 and the housing 1, a second elastic member 42 configured to maintain the button 2 in the initial position is further provided. The second elastic member 42 allows the button 2 to elastically return from the pressed position to the initial position. The implementation of the first movement limiting structure 201 and the second elastic member 42 will not be repeated here again.

[0055] In this embodiment, two locking members 3 are operably connected to the same button 2, but in another embodiment, one button 2 is configured to be operably connected to one locking member 3. Furthermore, in this embodiment, the inclined surface 220 is formed on the inner end 22 of the button 2 to bias each locking member 3 to rotate, but in another embodiment, it should be understood that the inclined surface is disposed on the first end 301a of the locking member 3, or on both the inner end 22 of the button 2 and the first end 301a of the locking member 3. Therefore, when the button 2 is pressed from the initial position to the pressed position, the inner end 22 of the button 2 and the first end 301a of the locking member 3 rotate the locking member 3 through the contact of the inclined surface, and the second hook 3a2 is switched from the locked position to the unlocked position. Furthermore, the embodiment of the first elastic member 41 is not limited to the reset piece.

[0056] 20 to 25, there is shown generally a side impact protection block 100 according to another embodiment of the present disclosure, and a mounting base 5 cooperating with the side impact protection block 100. The main difference between this embodiment and the previous embodiment is in the structure of the side impact protection block 100.

[0057] 21 and 23 to 25, the mounting base 5 has a mounting groove 50 similar to the other embodiments, and the mounting groove 50 is configured to partially accommodate the housing 1 of the side impact protection block 100. At least a portion of the bottom wall 13 and the side wall 12 of the housing 1 are accommodated in the mounting groove 50. A locking hole 5011 is provided in the side wall 501 of the mounting groove 50, and the locking portion of the locking member 3 is configured to fit into the locking hole 5011.

[0058] An end cap 51 is disposed in the mounting groove 50 of the mounting base 5. When the side impact protection block 100 is not mounted in the mounting groove 50, the end cap 51 blocks the opening of the mounting groove 50. The end cap 51 is supported at the opening of the mounting groove 50 by, for example, at least one fourth elastic member 53 in the mounting groove 50. When the side impact protection block 100 is mounted in the mounting groove 50, the end cap 51 compresses the fourth elastic member 53 after receiving the pressing force of the bottom wall 13 of the housing 1. When the end cap 51 moves toward the bottom 502 of the mounting groove 50, the locking hole 5011 in the side wall 501 of the mounting groove 50 is exposed at the same time, so as to be locked with the locking portion of the locking member 3 of the side impact protection block 100. One or more third elastic arms 511 are disposed in the end cap 51, and the third elastic arms 511 include a hook 511a. The side wall 501 of the mounting groove 50 is provided with one or more second slide holes 5012. The hooks 511a engage with the locking ends 5012a of the second slide holes 5012 to fix the end cap 51 in a position to close the opening of the mounting groove 50. When the end cap 51 is subjected to a pressing force, the hooks 511a move along the second slide holes 5012, and the side impact protection block 100 is inserted into the mounting groove 50, exposing the locking holes 5011 to cooperate with the locking portion of the locking member 3.

[0059] In some embodiments, the fourth resilient member 53 includes two spaced apart springs to provide sufficient support for the larger area end cap 51. In other embodiments, the fourth resilient member 53 includes only one spring or multiple springs.

[0060] In some embodiments, the at least one locking hole 5011 is aligned with the locking end 5012a of the at least one second slide hole 5012, which is beneficial for simplifying the manufacturing process.

[0061] Referring to FIG. 22, in this embodiment, the housing 1 includes a fifth housing part 105 and a sixth housing part 106. Referring to FIG. 23 and FIG. 24, the fifth housing part 105 includes a first hollow cavity 1050 having an opening at its bottom, and a top wall 1051 of the fifth housing part 105 forms the top wall 11 of the housing 1. The side impact contact surface 110 is located at the top wall 1051 of the fifth housing part 105, and the fifth housing part 105 has a side wall 1052. The sixth housing part 106 includes a second hollow cavity 1060 having an opening at its top, and an extension plate 1061 provided at the top port of the second hollow cavity 1060. The extension plate 1061 extends outward from the top port of the second hollow cavity 1060 and is assembled to the bottom opening of the fifth housing part 105. The sixth housing portion 106 has a side wall 1062. A bottom wall 1063 of the sixth housing portion 106 forms the bottom wall 13 of the housing 1. The sixth housing portion 106 further includes a third set of rib plates 1064 located on the extension plate 1061. The third set of rib plates 1064 extend into the first hollow cavity 1050 and are configured to reinforce the structural strength of the fifth housing portion 105.

[0062] The interior 10 of the housing 1 is surrounded by a first hollow cavity 1050 and a second hollow cavity 1060. The side walls 12 of the housing 1 include a side wall 1052 of the fifth housing part 105 and a side wall 1062 of the sixth housing part 106. The button 2 is provided in a button hole 120 that communicates with the side walls 12 of the housing 1. In this embodiment, the button hole 120 communicates with the side wall 1052 of the fifth housing part 105. The outer end 21 of the button 2 is configured to withstand a pressing force, and the inner end 22 of the button 2 extends into the interior 10 of the housing 1. In this embodiment, referring to FIG. 23, when the button 2 is in the initial position, the outer end 21 of the button 2 protrudes from the side wall 1052.

[0063] 23 and 24, the locking member 3 includes a first locking member 311 disposed in the interior 10 of the housing 1, and the first end 311a of the first locking member 311 is pivotally connected to the inner end 22 of the button 2 via a third pin shaft 393 such that the first end 311a of the first locking member 311 is operably connected to the button 2. The locking portion includes a third hook 3a3 disposed in a second end 311b of the first locking member 311, and an intermediate portion of the first locking member 311 is pivotally coupled to the housing 1 via a second pin shaft 392, which is attached, for example, to a hole 1045 of the third rib plate set 1064. The side wall 12 of the housing 1 is provided with a second through hole 1202 allowing the third hook 3a3 to extend therethrough, the second through hole 1202 being arranged, for example, in the side wall 1062 of the sixth housing part 106.

[0064] A third elastic member 43 is further disposed inside 10 of housing 1, and the third elastic member 43 acts on first locking member 311 to maintain the third hook 3a3 in a locked state extending from the second through hole 1202, and maintains the button 2 in the initial position. When the outer end 21 of the button 2 is pressed and switched from the initial position to the pressed position, the inner end 22 of the button 2 drives the first locking member 311 to pivot about the second pin shaft 392, and the third hook 3a3 overcomes the biasing force of the third elastic member 43 and is switched to an unlocked state in which it retreats from the second through hole 1202. When the pressing force applied to the button 2 is removed, the third elastic member 43 automatically drives the first locking member 311 to rotate about the second pin shaft 392, and the third hook 3a3 elastically returns to the locked state, and the button 2 elastically returns to the initial position. In some embodiments, the third resilient member 43 is disposed, for example, between the first locking member 311 and a portion of a rib plate of the third rib plate set 1064.

[0065] 23 and 24, the locking member 3 further includes a second locking member 312 disposed in the interior 10 of the housing 1. A first end 312a of the second locking member 312 is fixedly connected to a middle portion of the button 2, whereby the second locking member 312 is indirectly connected to the first end 311a of the first locking member 311 via the button 2, and the button 2 is operably connected to the second locking member 312. Correspondingly, the locking portion includes a fourth hook 3a4 disposed in the second end 312b of the second locking member 312, and the bending direction of the fourth hook 3a4 is opposite to the bending direction of the third hook 3a3. The side wall 12 of the housing 1 includes a third through hole 1203 that allows the fourth hook 3a4 to extend therethrough, and the third through hole 1203 is disposed in, for example, the side wall 1062 of the sixth housing part 106. In some embodiments, the second locking member 312 and the button 2 are integrally formed.

[0066] The third elastic member 43 in this embodiment is a spring. Both ends of the spring are attached to the first locking member 311 and the second locking member 312, respectively. For example, referring to FIG. 24, the first locking member 311 and the second locking member 312 are provided with a columnar body 30a, and both ends of the spring are sleeved in the columnar body 30a. Referring to FIG. 23, when the button 2 is in the initial position, the third elastic member 43 also acts on the second locking member 312, and the fourth hook 3a4 is maintained in a locked state in which it protrudes from the third through hole 1203. Referring to FIG. 24, when the button 2 is moved from the initial position to the pressed position by a pressing force, the button 2 moves together with the second locking member 312, overcomes the biasing force of the third elastic member 43, and is switched to an unlocked state in which the fourth hook 3a4 retreats from the third through hole 1203.

[0067] In some embodiments, a second travel limiting structure 202 is provided between the button 2 and the housing 1, and the second travel limiting structure 202 is configured to limit the stroke of the button 2 between an initial position and a pressed position. The second travel limiting structure 202 is implemented in various ways. For example, in one embodiment, referring to FIG. 22, the second travel limiting structure 202 includes a limiting pin 2021 and a first sliding hole 2022. The limiting pin 2021 is attached to the button 2, and the first sliding hole 2022 is disposed in the housing 1. For example, the first sliding hole 2022 is disposed on the third rib plate set 1064. The limiting pin 2021 slidably cooperates with the first sliding hole 2022, and the limit sliding position of the limiting pin 2021 is limited by both ends of the first sliding hole 2022, so that the stroke of the button 2 is limited.

[0068] 21, 23 and 25, the side impact protection block 100 of this embodiment is attached to the mounting groove 50 of the mounting base 5 in the same manner as in the other embodiments. For example, the side impact protection block 100 moves along the direction of the arrow P, and the bottom wall 13 pushes the end cap 51 and moves toward the bottom 502 of the mounting groove 50. When the housing 1 of the side impact protection block 100 is inserted into a predetermined position, the third hook 3a3 and the fourth hook 3a4 are locked in the corresponding lock holes 5011. When it is necessary to remove the side impact protection block 100, the button 2 is pressed from the initial position to the pressed position, and both the first lock member 311 and the second lock member 312 are driven to an unlocked state in which they are disengaged from the lock holes 5011. At this time, the side impact protection block 100 can be easily removed from the mounting groove 50.

The sixth housing portion 106 includes a side wall 1062, and a bottom wall 1063 of the sixth housing portion 106 forms the bottom wall 13 of the housing 1. The sixth housing portion 106 further includes a third set of rib plates 1064 located on the extension plate 1061, the third set of rib plates 1064 extending into the first hollow cavity 1050 and configured to reinforce the structural strength of the fifth housing portion 105.

[0071] The interior 10 of the housing 1 is surrounded by a first hollow cavity 1050 and a second hollow cavity 1060. The side walls 12 of the housing 1 include a side wall 1052 of the fifth housing part 105 and a side wall 1062 of the sixth housing part 106. The button 2 is provided in a button hole 120 that communicates with the side walls 12 of the housing 1. In this embodiment, the button hole 120 communicates with the side wall 1052 of the fifth housing part 105. The outer end 21 of the button 2 is configured to withstand a pressing force, and the inner end 22 of the button 2 extends into the interior 10 of the housing 1. Referring to FIG. 28, in this embodiment, when the button 2 is in the initial position, for example, the outer end 21 of the button 2 does not protrude from the side wall 1052.

[0072] 28 to 31, the locking member 3 includes a first locking member 311 and a second locking member 312 disposed inside 10 of the housing 1. A first end 312a of the second locking member 312 located between the inner end 22 of the button 2 and the first locking member 311 is pivotally connected to the housing 1 via a fifth pin shaft 395, and the fifth pin shaft 395 is attached, for example, to a hole 1046 of the third rib plate set 1064. An intermediate portion of the second locking member 312 is pivotally connected to a first end 311a of the first locking member 311 via a fourth pin shaft 394, and an intermediate portion of the first locking member 311 is pivotally connected to the housing 1 via a second pin shaft 392, and the second pin shaft 392 is attached, for example, to a hole 1045 of the third rib plate set 1064.

The second through hole 1202 and the third through hole 1203 are provided in, for example, the side wall 1062 of the sixth housing part 106.

[0073] The inner end 22 of the button 2 abuts against an intermediate portion of the second locking member 312 such that the button 2 is operably connected to the second locking member 312 and the button 2 is operably connected to the first end 311a of the first locking member 311.

[0074] A third elastic member 43 is further provided inside 10 of housing 1, and the third elastic member 43 acts on first locking member 311 and second locking member 312 to maintain a locked state in which third hook 3a3 and fourth hook 3a4 protrude from second through hole 1202 and third through hole 1203, respectively. At the same time, second locking member 312 abuts against inner end 22 of button 2, and therefore button 2 is maintained in the initial position. When outer end 21 of button 2 is switched from the initial position to the pressed position by receiving a pressing force, inner end 22 of button 2 is driven to pivot second locking member 312 about fifth pin shaft 395 against the biasing force of third elastic member 43, and fourth hook 3a4 is switched to an unlocked state in which it retreats from third through hole 1203.
