Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a locking mechanism, a seat and a vehicle. Background Art

[0002] For models with three rows of seats, the second row of seats is required to have an easy entry function. When the third row of passengers needs to enter, the seats can slide and fold, so that the passengers have enough space to enter the third row.

[0003] In order to prevent the seats from colliding with other passengers when the passengers enter the third row, the second row seats are usually provided with a seat locking mechanism, which can keep the second row seats in a flipped state. However, the existing seat locking mechanism is not convenient to install and remove, and cannot be quickly installed or removed from the seats. Utility Model Content

[0004] The present application provides a locking mechanism, a seat and a vehicle, which are used to solve the problem that the existing seat locking mechanism is not convenient to install and disassemble.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] On the one hand, an embodiment of the present application provides a locking mechanism, including a mounting member, a transmission member, and a locking assembly. The transmission member is rotationally connected to the mounting member. The locking assembly is mounted on the mounting member. The locking assembly is used to abut against a part of the transmission member during the rotation of the transmission member to limit the rotation connection of the transmission member.

[0007] The locking mechanism provided in the embodiment of the present application has a locking assembly that abuts against a portion of the transmission member during the rotation of the transmission member to limit the rotation connection of the transmission member. The locking assembly can limit the rotation of the transmission member, thereby limiting the rotation of the second row of seats connected to the transmission member, so that the second row of seats remains in the flipped state.

[0008] In the actual installation process, since the transmission part is installed on the mounting part and the locking assembly is installed on the mounting part, the locking mechanism can be used as a relatively independent installation module. When the position of the mounting part changes, the positions of the transmission part and the locking assembly also change accordingly. After the locking mechanism is installed, the relative position between the transmission part and the locking assembly will not change, and the staff does not need to consider the coordination effect between the transmission part and the locking assembly after installation, which greatly reduces the difficulty of installing the locking mechanism.

[0009] In some embodiments, the mounting member includes a first mounting member and a second mounting member. At least a portion of the second mounting member is disposed relative to at least a portion of the first mounting member. The transmission member and the locking assembly are disposed between the first mounting member and the second mounting member.

[0010] In some embodiments, a rotation hole is provided on the transmission member. The mounting member further comprises a rotation shaft. At least a portion of the rotation shaft is located between the first mounting member and the second mounting member, and is connected to at least one of the first mounting member and the second mounting member. The rotation shaft is inserted into the rotation hole and is rotationally connected to the transmission member.

[0011] In some embodiments, a first through hole is formed on the first mounting member, a second through hole is formed on the second mounting member, and the rotating shaft is passed through the first through hole and the second through hole. A first mounting portion and a second mounting portion are respectively formed at both ends of the transmission shaft, the first mounting portion abuts against a side of the first mounting member away from the second mounting member, and the second mounting portion abuts against a side of the second mounting member away from the first mounting member.

[0012] In some embodiments, the locking assembly includes a locking member and an elastic member. The locking member is located on the peripheral side of the transmission member, and is rotationally connected to at least one of the first mounting member and the second mounting member, and the rotation axis of the locking member is parallel to the rotation axis of the transmission member. A portion of the locking member is used to abut against a portion of the transmission member during the rotation of the transmission member. One end of the elastic member is connected to the first mounting member or the second mounting member, and the other end is connected to the locking member, and is used to keep the locking member and the transmission member in abutment to limit the rotation of the transmission member.

[0013] In some embodiments, a plurality of first teeth are formed on one side of the transmission member close to the locking member, and a plurality of second teeth are formed on one side of the locking member close to the transmission member. The plurality of second teeth are used to engage with the plurality of first teeth to limit the rotation of the transmission member.

[0014] In some embodiments, a connection hole is provided on the locking member. The locking assembly further comprises a connection member. The connection member is inserted into the connection hole and connected to at least one of the first mounting member and the second mounting member. The elastic member is a torsion spring, which is sleeved on the connection member, one end of which is connected to the locking member, and the other end of which is connected to the first mounting member or the second mounting member.

[0015] In some embodiments, one end of the connecting member is connected to the second mounting member, and abutment portion is formed on the connecting member. The abutment portion is located on a side of the locking member close to the second mounting member and abuts against the locking member.

[0016] On the other hand, an embodiment of the present application further provides a seat, comprising the above-mentioned locking mechanism.

[0017] On the other hand, an embodiment of the present application further provides a vehicle, comprising the above-mentioned seat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In the description of the present application, it should be understood that the terms, "up", "down", "left", "right", "front", "back", "inside", "outside", "center", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0025] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more.

[0027] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0028] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0029] In some related technologies, in order to facilitate passengers to sit in the third row of seats, a slide rail is usually provided inside the vehicle, and the second row of seats is slidably arranged on the slide rail. When the third row of passengers get on the vehicle, the second row of seats can be slid toward the front of the vehicle, and as the second row of seats slide toward the front of the vehicle, the space for passengers to enter the third row of seats is also increased.

[0030] The second row of seats may include a bottom bracket and a seat body. The bottom bracket is slidably arranged on the slide rail, and one end of the seat body close to the front of the vehicle is rotatably connected to the bottom bracket. In this way, in actual application, when the third row of passengers get on the vehicle, the seat body can be folded toward the front of the vehicle, thereby ensuring that there is sufficient space for the passengers to get on the vehicle.

[0031] In order to prevent the second-row seats from colliding with passengers when they get on the vehicle, the second-row seats are also equipped with a seat locking mechanism. The seat locking mechanism can limit the rotation of the seat body so that the seat body remains in a flipped state facing the front of the vehicle, thereby preventing the seat body from colliding with passengers when they enter the third row space.

[0032] Each part of the existing seat locking mechanism needs to be connected to different parts of the seat respectively, and the size requirements of each part are high. The installation and disassembly process is relatively complicated, and it is not convenient to install and disassemble the seat.

[0033] Based on this, an embodiment of the present application provides a vehicle, the vehicle includes a vehicle body and seats. The seats include two rows of seats and three rows of seats. The two rows of seats and the three rows of seats are both used for passengers to sit.

[0034] It is understandable that the vehicle provided in the embodiment of the present application may also include other components, such as an engine, a transmission mechanism, etc., to realize the basic functions of the vehicle.

[0035] Among them, Figure 1 As shown, Figure 1 This is a schematic diagram of the partial structure of a second-row seat 110 provided in an embodiment of the present application. The second-row seat 110 may include a seat body 120 , a bottom bracket 130 and a locking mechanism 100 .

[0036] The seat body 120 is rotatably connected to the bottom bracket 130. In this way, the seat body 120 can rotate relative to the bottom bracket 130. In actual application, along the length direction of the vehicle, one end of the seat body 120 close to the front of the vehicle can be rotatably connected to the bottom bracket 130. In this way, when the seat body 120 rotates along the bottom bracket 130, the seat body 120 can be flipped toward the front of the vehicle, thereby providing a larger ingress and egress space for passengers, so as to facilitate passengers to enter the third row of seats.

[0037] The locking mechanism 100 is connected to the seat body 120 and the bottom bracket 130 to limit the rotation of the seat body 120. In this way, after the seat body 120 is flipped, the locking mechanism 100 can keep the seat body 120 in the flipped state to prevent the seat body 120 from rotating back and colliding with the passengers when the passengers enter the third row.

[0038] The bottom bracket 130 can be slidably connected to the slide rail of the vehicle. In this way, the bottom bracket 130 can slide along the slide rail to change the position of the second row of seats 110. Exemplarily, the slide rail can be laid along the length of the vehicle, and the bottom bracket 130 can slide along the slide rail toward the front of the vehicle, thereby providing a larger ingress and egress space for passengers to facilitate passengers to enter the third row of seats.

[0039] Next, the locking mechanism 100 provided in the embodiment of the present application is further introduced. Figure 2 As shown, Figure 2 This is a structural schematic diagram of the locking mechanism 100 and the driving member 140 provided in an embodiment of the present application. The locking mechanism 100 may include a mounting member 1, a transmission member 2 and a locking assembly 3.

[0040] The transmission member 2 is rotatably connected to the mounting member 1. In this way, the transmission member 2 can rotate relative to the mounting member 1. In the actual application process, Figure 1 As shown, the transmission member 2 can be connected to a portion of the second row of seats 110 so as to rotate together with the second row of seats 110 when the second row of seats 110 rotates.

[0041] like Figure 2 As shown, the locking assembly 3 is mounted on the mounting member 1. The locking assembly 3 is used to abut against a portion of the transmission member 2 during the rotation of the transmission member 2 to limit the rotation connection of the transmission member 2. In this way, the locking assembly 3 can limit the rotation of the transmission member 2, thereby limiting the second row of seats 110 ( Figure 1 ) to keep the second row of seats 110 in the flipped state.

[0042] In the actual installation process, since the transmission member 2 is installed on the mounting member 1 and the locking assembly 3 is installed on the mounting member 1, the locking mechanism 100 can be used as a relatively independent installation module. When the position of the mounting member 1 changes, the positions of the transmission member 2 and the locking assembly 3 also change accordingly. After the mounting member 1 is installed, the positions of the transmission member 2 and the locking assembly 3 are also fixed. During the installation of the mounting member 1, the matching accuracy between the transmission member 2 and the locking assembly 3 will not change, which greatly reduces the installation difficulty of the locking mechanism 100.

[0043] At the same time, the staff can flexibly adjust the installation position of the installation member 1 on the second row of seats 110 according to the needs, and it is only necessary to ensure that the transmission member 2 can rotate together with the rotation of the second row of seats 110. In this way, the installation accuracy requirements of the locking mechanism 100 can be reduced.

[0044] In order to realize that the transmission member 2 can rotate together with the second row of seats 110, in some embodiments, such as Figure 2 As shown, a connecting portion 22 is formed on the peripheral side of the transmission member 2. Figure 1 As shown, the second row seat 110 may further include a driving member 140. One end of the driving member 140 is rotatably connected to the seat body 120, and the other end is rotatably connected to the mounting member 1. In this way, the driving member 140 can rotate relative to the seat body 120 and the mounting member 1.

[0045] The driving member 140 is formed with a driving portion 1401, and the driving portion 1401 is spaced apart from both ends of the driving member 140. The driving portion 1401 is used to connect with the connecting portion 22 ( Figure 2 ) is connected to drive the connecting portion 22 to rotate synchronously with the driving member 140. In this way, during the rotation of the seat body 120, the driving member 140 can drive the transmission member 2 to rotate.

[0046] For example, in actual application, the driving member 140 can also be rotatably connected to the bottom bracket 130. It only needs to ensure that the rotation axis of one end of the driving member 140 connected to the mounting member 1 or the bottom bracket 130 coincides with the rotation axis of the transmission member 2, and the driving part 1401 can drive the transmission member 2 to rotate synchronously.

[0047] Accordingly, when the transmission member 2 is locked by the locking assembly 3 ( Figure 2 ) is restricted from rotating, the driving member 140 is also unable to rotate, and the position of the second row of seats 110 can be fixed, so as to be kept in a certain position. For example, the second row of seats 110 can be kept in a position that is convenient for people to enter the third row space.

[0048] For example, Figure 2 As shown, the driving portion 1401 and the connecting portion 22 can both be connecting holes, and bolts are passed through the driving portion 1401 and the connecting portion 22 to connect the driving member 140 and the transmission member 2 together.

[0049] It is understandable that the driving member 140 can also be connected to the connecting portion 22 in other ways, as long as the driving member 140 can drive the transmission member 2 to rotate synchronously after the connection. Exemplarily, the driving member 140 can also be connected to the connecting portion 22 in the form of welding.

[0050] In some embodiments, Figure 2 As shown, the mounting member 1 may include a first mounting member 11 and a second mounting member 12. At least a portion of the second mounting member 12 is disposed relative to at least a portion of the first mounting member 11. The transmission member 2 and the locking assembly 3 are disposed between the first mounting member 11 and the second mounting member 12.

[0051] In this way, the first mounting member 11 and the second mounting member 12 can provide mounting positions for the transmission member 2 and the locking assembly 3. The first mounting member 11 and the second mounting member 12 can provide protection for the locking assembly 3 and reduce the collision of the first mounting member 11 and the second mounting member 12.

[0052] In the actual application process, Figure 1 As shown, the number of the locking mechanisms 100 may be two, and the two locking mechanisms 100 are relatively arranged on both sides of the second row of seats 110. The first mounting member 11 ( Figure 2 ) is located at the second mounting member 12 ( Figure 2 ) is close to one side of the bottom bracket 130.

[0053] like Figure 2As shown, a connecting hole 111 is provided on the first mounting member 11, and the mounting member 1 may further include a connecting nut 13 and a connecting bolt (not shown in the figure). The connecting nut 13 is located on a side of the first mounting member 11 close to the second mounting member 12. One end of the connecting bolt is connected to the bottom bracket 130, and the connecting nut 13 is connected to the threaded end of the connecting bolt. In this way, the first mounting member 11 and the bottom bracket 130 can be connected together.

[0054] It is understandable that the first mounting member 11 can also be connected to the bottom bracket 130 in other ways, as long as the first mounting member 11 can be stably fixed to the bottom bracket 130. For example, the first mounting member 11 can be welded to the bottom bracket 130. Alternatively, a clamping portion (not shown) can be formed on the first mounting member 11, and a connecting portion can be formed on the bottom bracket 130, and the clamping portion and the connecting portion are clamped with each other, so that the first mounting member 11 is fixed to the bottom bracket 130.

[0055] In order to realize the rotation connection between the transmission member 2 and the mounting member 1, in some embodiments, as Figure 2 As shown, the mounting member 1 may further include a rotation shaft 14. At least a portion of the rotation shaft 14 is located between the first mounting member 11 and the second mounting member 12, and is connected to at least one of the first mounting member 11 and the second mounting member 12. In this way, the position of the rotation shaft 14 can be fixed.

[0056] The transmission member 2 is provided with a rotation hole 24, and the rotation shaft 14 is passed through the rotation hole 24 and is rotationally connected with the transmission member 2. In this way, the transmission member 2 can rotate around the rotation shaft 14, thereby realizing the rotation connection between the transmission member 2 and the mounting member 1.

[0057] In some embodiments, Figure 2 As shown, a first through hole 112 is formed on the first mounting member 11, and a second through hole 121 is formed on the second mounting member 12. The rotating shaft 14 is passed through the first through hole 112 and the second through hole 121. The first through hole 112 and the second through hole 121 can provide a mounting position for the rotating shaft 14.

[0058] A first mounting portion 141 and a second mounting portion (not shown) are respectively formed at both ends of the rotating shaft 14, the first mounting portion 141 abuts against a side of the first mounting member 11 away from the second mounting member 12, and the second mounting portion abuts against a side of the second mounting member 12 away from the first mounting member 11. In this way, the first mounting portion 141 and the second mounting portion can restrict the first mounting member 11 and the second mounting member 12 from moving in a direction away from each other.

[0059] For example, Figure 2As shown, the rotating shaft 14 can be cylindrical, and a boss is formed on the circumference of one end of the rotating shaft 14, and the boss can serve as a first mounting portion 141 to abut against a side of the first mounting member 11 away from the second mounting member 12. After the rotating shaft 14 passes through the first mounting member 11 and the second mounting member 12, one end of the rotating shaft 14 located on the side of the second mounting member 12 away from the first mounting member 11 can be turned outward to form a second connecting portion, and the second connecting portion abuts against a side of the second mounting member 12 away from the first mounting member 11.

[0060] In some embodiments, Figure 1 As shown, the locking mechanism 100 may further include a fixing bolt 4. The fixing bolt 4 is passed through an opening in the middle of the rotating shaft 14 and connected to the bottom bracket 130. In this way, the fixing bolt 4 can further fix the position of the mounting member 1.

[0061] It is understandable that there are many ways to connect the fixing bolt 4 to the bottom bracket 130. For example, the bottom bracket 130 may be provided with a threaded hole, and the fixing bolt 4 may be directly connected to the threaded hole. Alternatively, the bottom bracket 130 may be provided with a through hole, and the fixing bolt 4 may pass through the through hole and be locked with a nut, so that the fixing bolt 4 and the bottom bracket 130 can also be fixed together.

[0062] In some embodiments, Figure 2 As shown, a portion of the first mounting member 11 is formed with a protrusion 113 in a direction close to the second mounting member 12. A limiting groove 122 is formed on the second mounting member 12, and the protrusion 113 is inserted into the limiting groove 122. In actual application, the protrusion 113 is inserted into the limiting groove 122 to limit the rotation of the second mounting member 12 relative to the first mounting member 11.

[0063] In some embodiments, Figure 2 As shown, along the first direction X, the protrusion 113 and the first through hole 112 are arranged at intervals. In this way, along the first direction X, a plurality of connection positions are formed between the first mounting member 11 and the second mounting member 12, and the connection between the first mounting member 11 and the second mounting member 12 is more stable.

[0064] In some embodiments, Figure 2 As shown, the portion of the protrusion 113 inserted into the limiting groove 122 can be welded to the inner wall of the limiting groove 122. In this way, the connection between the first mounting member 11 and the second mounting member 12 is firm, and the second mounting member 12 is not easy to be separated from the first mounting member 11.

[0065] In some embodiments, Figure 2 As shown, the second mounting member 12 is located at Figure 2The upper left end of the middle portion is bent toward the direction close to the first mounting member 11 to form a third mounting portion 123, and the end of the first mounting member 11 opposite to the third mounting portion 123 is bent toward the direction close to the second mounting member 12 to form a fourth mounting portion 114. Along the first direction X, the third mounting portion 123 and the fourth mounting portion 114 are stacked and fixedly connected by welding. In this way, the stability of the connection between the first mounting member 11 and the second mounting member 12 can be further improved.

[0066] In some embodiments, Figure 2 As shown, the locking assembly 3 may include a locking member 31. The locking member 31 is located on the peripheral side of the transmission member 2 and is rotatably connected to at least one of the first mounting member 11 and the second mounting member 12. The rotation axis of the locking member 31 is parallel to the rotation axis of the transmission member 2, and a portion of the locking member 31 is used to abut against a portion of the transmission member 2 during the rotation of the transmission member 2.

[0067] Since a portion of the locking member 31 is used to abut against a portion of the transmission member 2 during the rotation of the transmission member 2, the locking member 31 can limit the rotation of the transmission member 2, thereby making the second row of seats 110 ( Figure 1 ) is fixed at a specific angle, for example, so that the second row of seats 110 is fixed in a position that facilitates passengers to enter the third row space.

[0068] Since the locking member 31 is located on the circumferential side of the transmission member 2 and is rotationally connected to at least one of the first mounting member 11 and the second mounting member 12, the rotation axis of the locking member 31 is parallel to the rotation axis of the transmission member 2. As the locking member 31 rotates, the locking member 31 can abut against or separate from the transmission member 2.

[0069] When the locking member 31 rotates to abut against the transmission member 2, the locking member 31 can limit the rotation of the transmission member 2, so that the transmission member 2 and the second row of seats 110 connected thereto are kept in a fixed position. When the locking member 31 rotates to separate from the transmission member 2, the locking member 31 no longer limits the rotation of the transmission member 2, and the transmission member 2 can rotate together with the second row of seats 110.

[0070] In some embodiments, Figure 2 As shown, the locking assembly 3 may further include an elastic member 32. One end of the elastic member 32 is connected to the first mounting member 11 or the second mounting member 12, and the other end is connected to the locking member 31. In this way, the elastic member 32 can limit the locking member 31 from rotating relative to the mounting member 1.

[0071] The elastic member 32 is used to keep the locking member 31 and the transmission member 2 against each other to limit the rotation of the transmission member 2. The elastic member 32 can drive the portion of the locking member 31 against which the transmission member 2 abuts to move toward the direction close to the transmission member 2, so that the locking member 31 and the transmission member 2 abut against each other.

[0072] It is understandable that, since the elastic member 32 has elastic force, the elastic member 32 can be stretched or compressed. Thus, in actual application, the user can apply external force to make the locking member 31 overcome the elastic force of the elastic member 32 and separate from the transmission member 2. In this way, the transmission member 2 can be in the second row of seats 110 ( Figure 1 ) is driven to rotate.

[0073] In some embodiments, Figure 2 As shown, a plurality of first teeth 21 are formed on one side of the transmission member 2 close to the locking member 31, and a plurality of second teeth 311 are formed on one side of the locking member 31 close to the transmission member 2. The plurality of second teeth 311 are used to mesh with the plurality of first teeth 21 to limit the rotation of the transmission member 2.

[0074] In actual application, when the first toothed portion 21 and the second toothed portion 311 are meshed with each other, a good stabilizing effect is achieved, and the transmission member 2 is not easy to rotate.

[0075] Since the number of the first toothed portions 21 and the second toothed portions 311 are both plural, the plurality of first toothed portions 21 and the plurality of second toothed portions 311 can have a plurality of different meshing states. As the meshing states of the plurality of first toothed portions 21 and the plurality of second toothed portions 311 change, the second row of seats 110 ( Figure 1 ) can be maintained at different rotation angles.

[0076] For example, Figure 2 As shown, the transmission member 2 is formed with a first arc surface on one side close to the locking member 31, and the first arc surface is a circular arc surface protruding toward the locking member 31. A plurality of first tooth-shaped portions 21 are evenly distributed on the first arc surface at equal intervals, and the plurality of first tooth-shaped portions 21 are arranged toward the locking member 31. Figure 2 Tilt to upper left center.

[0077] The locking member 31 has a second arc surface formed on one side close to the transmission member 2. The second arc surface is an arc surface that is concave away from the transmission member 2. A plurality of second tooth-shaped portions 311 are evenly distributed on the second arc surface at equal intervals, and the plurality of second tooth-shaped portions 311 are arranged toward Figure 2 Tilt to lower right center.

[0078] When the transmission member 2 moves along Figure 2 When the transmission member 2 rotates clockwise, the first teeth 21 can push the second teeth 311 to move away from the transmission member 2. At this time, the transmission member 2 can rotate normally. Figure 1 As shown, when the second row of seats 110 are along Figure 1 When the housing 2 is turned forward in the clockwise direction, the transmission member 2 can be driven to rotate together.

[0079] When the transmission member 2 moves along Figure 2 When the seat 20 is rotated counterclockwise, the first teeth 21 mesh with the second teeth 311. At this time, the elastic member 32 restricts the locking member 31 from rotating, and the locking member 31 restricts the transmission member 2 from rotating, so that the second row of seats 110 connected to the transmission member 2 is fixed at a certain position.

[0080] For example, Figure 3 As shown, Figure 3 This is a partial structural diagram of the second row of seats 110 in the flipped state provided in the embodiment of the present application. At this time, the stopper 31 ( Figure 2 ) in the elastic member 32 ( Figure 2 ) is driven to abut against the transmission member 2, and the plurality of first tooth-shaped portions 21 ( Figure 2 ) and a plurality of second tooth-shaped portions 311 ( Figure 2 ) engages, thereby limiting the transmission member 2 along Figure 3 The second row of seats 110 will not rotate counterclockwise in the counterclockwise direction of the rotation. In this way, the second row of seats 110 can remain in the rotated state, thereby reducing the risk of collision between the second row of seats 110 and the passenger during entry into the third row.

[0081] In the actual application process, Figure 1 As shown, when the second row of seats 110 is in a flat state, along the rotation direction of the transmission member 2, the plurality of first toothed portions 21 ( Figure 2 ) and a plurality of second tooth-shaped portions 311 ( Figure 2 ) are mutually staggered, and after the transmission member 2 rotates a certain angle in the clockwise direction, the plurality of first tooth-shaped portions 21 begin to mesh with the plurality of second tooth-shaped portions 311. In this way, when the second row of seats 110 is accidentally touched and rotates, the plurality of first tooth-shaped portions 21 will not mesh with the plurality of second tooth-shaped portions 311, and the second row of seats 110 can return to their original positions under the action of gravity.

[0082] In some embodiments, Figure 2 As shown, a connection hole 312 is formed on the locking member 31. The locking assembly 3 also includes a connection member 33. The connection member 33 is inserted into the connection hole 312 and connected to at least one of the first mounting member 11 and the second mounting member 12. In this way, the locking member 31 can rotate around the connection member 33, thereby rotating relative to the first mounting member 11 and the second mounting member 12.

[0083] For example, the locking member 31 may be arranged along Figure 2The locking member 31 rotates counterclockwise, and as the locking member 31 rotates, the second toothed portion 311 can be separated from the first toothed portion 21, and the transmission member 2 can move along the Figure 2 Turn counterclockwise to return to its original position.

[0084] Exemplarily, both ends of the connecting member 33 may be respectively connected to the first mounting member 11 and the second mounting member 12. In this way, the first mounting member 11 and the second mounting member 12 may respectively provide support forces for both ends of the connecting member 33, thereby ensuring the stability of the connecting member 33.

[0085] In some embodiments, the connecting member 33 may be a cylinder, so that the locking member 31 may rotate around the connecting member 33. Alternatively, both ends of the connecting member 33 may be rotatably connected to the first mounting member 11 and the second mounting member 12, so that the locking member 31 may rotate together with the connecting member 33.

[0086] In other embodiments, the locking member 31 can be fixedly connected to the connecting member 33. Both ends of the locking member 31 can be slidably connected to the first mounting member 11 and the second mounting member 12. The connecting member 33 is used to slide in a direction away from the transmission member 2 to separate the locking member 31 from the transmission member 2. In this way, when the transmission member 2 moves along Figure 1 When rotating in the clockwise direction, the first toothed portion 21 pushes the second toothed portion 311 , and at this time the locking member 31 can move along with the connecting member 33 in a direction away from the transmission member 2 , and the transmission member 2 can rotate normally.

[0087] Accordingly, when the locking member 31 moves away from the transmission member 2, the elastic potential energy of the elastic member 32 increases. After the transmission member 2 stops rotating, the elastic potential energy of the elastic member 32 is released, pushing the locking member 31 to move toward the transmission member 2, so that the second toothed portion 311 meshes with the first toothed portion 21. In this way, the locking member 31 can also limit the rotation of the transmission member 2.

[0088] In some embodiments, Figure 2 As shown, the elastic member 32 may be a torsion spring, which is sleeved on the connecting member 33, one end of which is connected to the locking member 31, and the other end of which is connected to the first mounting member 11 or the second mounting member 12. In this way, the torsion spring can provide a thrust for the locking member 31 to rotate toward the transmission member 2, and the connecting member 33 can provide support for the torsion spring, thereby reducing the risk of the torsion spring falling.

[0089] For example, Figure 2 As shown, a first limiting hole 124 is formed on the second mounting member 12, and a second limiting hole 314 is formed on the locking member 31. One end of the torsion spring is inserted into the first limiting hole 124, and the other end is inserted into the second limiting hole 314.

[0090] It is understandable that the elastic member 32 may also be other elastic elements, and for example, the elastic member 32 may also be a common spring or elastic rope. It is only necessary to ensure that the elastic member 32 can drive the locking member 31 to abut against the transmission member 2 to limit the rotation of the transmission member 2, and when the locking member 31 is pulled or pushed by an external force, it can be compressed or stretched so that the locking member 31 can be separated from the transmission member 2.

[0091] In some embodiments, one end of the connecting member 33 is connected to the second mounting member 12, and abutting portion 331 is formed on the connecting member 33. The abutting portion 331 is located on the side of the locking member 31 close to the second mounting member 12 and abuts against the locking member 31, and the side of the locking member 31 away from the abutting portion 331 abuts against the first mounting member 11. In this way, the abutting portion 331 and the first mounting member 11 can limit the movement of the locking member 31, so that the locking member 31 can be maintained at a position corresponding to the transmission member 2.

[0092] In some embodiments, the torsion spring may be sleeved around the abutting portion 331, with one end connected to the second mounting member 12 and the other end connected to the locking member 31. The abutting portion 331 may be supported on the inner side of the torsion spring to prevent the torsion spring from bending.

[0093] In other embodiments, the connecting member 33 may not have the abutting portion 331. Accordingly, a torsion spring may be disposed between the locking member 31 and the second mounting member 12, and the two ends of the torsion spring are respectively connected to the second mounting member 12 and the locking member 31. One end of the torsion spring abuts against a side of the second mounting member 12 close to the locking member 31, and the other end abuts against a side of the locking member 31 close to the second mounting member 12. In this way, the torsion spring can limit the locking member 31 so that the position of the locking member 31 corresponds to the transmission member 2.

[0094] In some embodiments, along the second direction Y, a second toothed portion 311 is formed at the top of the locking member 31, and a pushing portion 313 is formed at the bottom. Figure 1 As shown, a pusher 150 is provided on the bottom bracket 130. Along the sliding direction of the second row of seats 110, the pusher 313 ( Figure 2 ) at least a portion of which is arranged opposite to the pushing member 150. When the second row of seats 110 slides to the normal position, as the second row of seats 110 slides to a certain position, the pushing member 150 can push the pushing portion 313, thereby causing the locking member 31 to rotate counterclockwise.

[0095] As the locking member 31 rotates counterclockwise, the first toothed portion 21 and the second toothed portion 311 separate from each other, and the locking member 31 no longer restricts the rotation of the transmission member 2. At this time, the second row of seats 110 can be rotated to a flat state, thereby returning to the original position.

[0096] It is understandable that in actual application, the first toothed portion 21 and the second toothed portion 311 can be separated from each other by other means. For example, the user can manually pull the locking member 31 to rotate so that the locking member 31 and the transmission member 2 no longer abut against each other.

[0097] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
