Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a spare tire mounting assembly and vehicle. Background Technology

[0002] As an emergency component of a vehicle, the location of the spare tire directly affects the utilization of cargo space, and the ease of installation and removal significantly impacts its usability. Currently, spare tires are typically suspended under the chassis at the rear of the vehicle frame or located in other parts of the cargo compartment. However, existing spare tire installation and removal methods often present inconvenience, resulting in poor usability. Utility Model Content

[0003] In view of this, this application aims to provide a spare tire mounting assembly to facilitate the installation and removal of a spare tire.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: A spare tire mounting assembly includes a mounting mechanism and a loading / unloading guide mechanism located in the vehicle compartment; The mounting mechanism includes a spare tire mounting seat rotatably connected in the carriage, and a locking part disposed between the spare tire mounting seat and the carriage; The locking part can lock the spare tire mounting seat in a first state where it is placed horizontally in the vehicle compartment, and the unlocked spare tire mounting seat can be rotated to a second state where it is placed vertically in the vehicle compartment. The pick-and-place guide mechanism can be positioned below the spare tire mounting seat in the second state and is adapted to guide the spare tire to slide into or out of the vehicle compartment.

[0005] Furthermore, the spare tire mounting bracket includes a seat body with an internal cavity and a frame disposed on one side of the seat body; the frame is box-shaped with one end open, and the open end of the frame is connected to the seat body, and the frame is provided with mounting holes for mounting the spare tire.

[0006] Furthermore, the spare tire mounting bracket is provided with multiple limiting blocks, which can abut against the wheel hub of the spare tire to limit the radial displacement of the spare tire.

[0007] Furthermore, a limiting part is provided between the carriage and the spare tire mounting seat, and the limiting part and the locking part are located at the same end of the spare tire mounting seat; the limiting part is used to restrict the spare tire mounting seat from moving downward.

[0008] Furthermore, the pick-and-place guiding mechanism includes a guide member disposed in the carriage, the guide member having a guide groove, and the guide member being able to rotate relative to the carriage and switch between a storage state and a use state; a locking part is provided on the carriage, the locking part being used to lock the guide member in the storage state.

[0009] Furthermore, the guide member is telescopic to adjust the length of the guide groove.

[0010] Furthermore, the guide member includes a plurality of nested guide plates, each of which has a guide groove formed thereon; two adjacent guide plates are connected by an insertion part, the insertion part including a post on one of the guide plates and a sliding groove on the other guide plate, and the post can slide along the sliding groove to extend and retract the guide member.

[0011] Furthermore, the locking part includes a mounting groove on the carriage and a locking pin slidably disposed in the mounting groove, and a locking groove is provided on the guide member corresponding to the locking pin; the locking pin can slide from a first position to a second position in the mounting groove. In the first position, the locking pin slides into the locking groove and blocks one side of the guide member; in the second position, the locking pin slides out of the locking groove.

[0012] Furthermore, an assistive element is provided between the vehicle compartment and the spare tire mounting seat; the assistive element is adapted to apply rotational assistance to the spare tire mounting seat when the spare tire switches from the first state to the second state.

[0013] Compared with related technologies, this application has the following advantages: (1) The spare tire mounting assembly described in this application, through the setting of the spare tire mounting seat and the pick-and-place guide mechanism, can change the orientation of the spare tire by rotating the spare tire mounting seat. When the spare tire is in the first horizontal position, it can save space in the vehicle compartment. When the spare tire is in the second position, the removed spare tire can be carried by the pick-and-place guide mechanism, so that the spare tire can roll along the pick-and-place guide mechanism, replacing the operation of moving and lifting the spare tire, thereby facilitating the removal and installation of the spare tire in the vehicle compartment and improving the convenience of using the spare tire. At the same time, the locking part can lock the spare tire mounting seat, keeping the spare tire in the first position, preventing the spare tire mounting seat from shaking due to vehicle movement, so as to ensure driving safety.

[0014] (2) By setting a seat body with an internal cavity, the overall weight of the mounting base can be reduced while ensuring the structural strength of the seat body, making it easier to drive the mounting base to rotate, and providing sufficient installation space for the locking part. At the same time, a box-shaped frame is set and the open end of the frame is connected to the seat body to form a stable box structure, which provides a stable installation base for the spare tire. Furthermore, the hollow interior of the frame further reduces the overall weight of the mounting base.

[0015] (3) By setting the limit block, it can abut against the spare tire, thereby forming a support for the spare tire, so as to restrict the edge part of the spare tire from moving relative to the mounting seat along the axial direction of the spare tire itself, thereby preventing the spare tire from shaking on the spare tire mounting seat, thus improving the stability of the spare tire installation.

[0016] (4) By setting the limiting part, a support can be formed for the end of the spare tire mounting seat away from the hinge structure, so as to prevent the spare tire mounting seat from falling due to the weight of the spare tire, avoid interference between the spare tire mounting seat and other components in the vehicle compartment, and prevent the hinge structure from twisting or being damaged due to the falling of the spare tire mounting seat, so as to ensure the smooth rotation of the spare tire mounting seat. At the same time, it ensures the smooth locking of the locking part.

[0017] (5) By rotating the guide member onto the carriage, the guide member can rest against the side of the carriage in the retracted state, and can be positioned under the spare tire by rotating the guide member. Thus, by switching the state of the guide member, the guiding effect on the spare tire can be ensured while reducing the space occupied inside the carriage. At the same time, the locking part can fix the guide member in the retracted state, which can prevent the guide member from shaking and colliding with the cargo in the carriage when the vehicle is in motion, and avoid the generation of abnormal noise.

[0018] (6) By setting a retractable guide to change the length of the guide groove, the rolling path of the spare tire can be extended, providing long-distance rolling support for the spare tire, so as to facilitate the removal of the spare tire from the carriage. Furthermore, when the guide is in the retracted state, it can be driven to retract, further reducing the space occupied by the guide in the carriage, facilitating storage, and thus improving the utilization rate of the space in the carriage.

[0019] (7) By setting multiple guide plates, each guide plate has a guide groove. When the guide member extends or retracts, the continuity of the guide groove can be ensured, so that the spare tire can roll along a stable path, thereby improving the smoothness of the spare tire loading and unloading process. At the same time, by cooperating with the sliding groove and the insert, the relative sliding between adjacent guide plates can be guided, thereby providing guidance and limiting effect for the overall extension and retraction of the guide member, ensuring the smoothness of the extension and retraction process of the guide member, and facilitating the use of the guide member.

[0020] (8) Through the setting of the mounting groove, locking groove and locking pin, when the guide is in the retracted state, the locking groove can partially overlap with the mounting groove. At this time, by pushing the locking pin along the mounting groove into the locking groove, it is blocked on one side of the guide to restrict the rotation of the guide and ensure the locking effect of the guide. At the same time, the locking and unlocking of the guide can be completed simply by driving the locking pin to slide along the mounting groove. The operation steps are simple, which can shorten the time of guide state switching and thus improve the operation efficiency of spare tire loading and unloading.

[0021] (9) By setting an assistive element, the spare tire mounting seat can be assisted during rotation, thereby reducing the operating force required to rotate the spare tire mounting seat and improving the ease of use. At the same time, the assistive element can limit the rotation speed and rotation range of the spare tire mounting seat to prevent it from rotating too fast or too wide, thus avoiding collisions with the user, the carriage, and the cargo inside the carriage, and ensuring safety when switching the spare tire arrangement.

[0022] Another object of this application is to provide a vehicle having a spare tire mounting assembly as described above.

[0023] The vehicle and spare tire mounting assembly described in this application have the same technical effects as related technologies, and will not be described in detail here. Attached Figure Description

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a spare tire mounting assembly.

[0032] In related technologies, spare tires are typically suspended under the chassis at the rear of the vehicle frame or located in other positions within the vehicle compartment. However, current spare tire installation methods often suffer from the disadvantage of inconvenient installation and removal, resulting in poor usability of the spare tire.

[0033] In view of this, in order to overcome the shortcomings of the related technology, the spare tire mounting assembly in this embodiment combines... Figures 1 to 3 As shown, the overall design includes an installation mechanism and a pick-and-place guide mechanism located in the carriage 8.

[0034] The mounting mechanism includes a spare tire mounting seat 1 rotatably connected to the carriage 8, and a locking part disposed between the spare tire mounting seat 1 and the carriage 8. The locking part can lock the spare tire mounting seat 1 in a first state where it is transversely placed in the carriage 8, and the spare tire mounting seat 1 can be rotated to a second state where it is longitudinally placed in the carriage 8 after being unlocked. The loading and unloading guide mechanism can be located below the spare tire mounting seat 1 in the second state and is adapted to guide the spare tire 3 to slide into or out of the carriage 8.

[0035] Therefore, by configuring the spare tire mounting seat 1 and the guide mechanism, the orientation of the spare tire 3 can be changed by rotating the spare tire mounting seat 1. When the spare tire 3 is in the first horizontal position, space in the cargo compartment 8 can be saved. When the spare tire 3 is in the second position, the removed spare tire 3 can be supported by the guide mechanism, allowing the spare tire 3 to roll along the guide mechanism. This replaces the operation of moving and lifting the spare tire 3, thus facilitating the installation and removal of the spare tire 3 on the cargo compartment 8 and improving the ease of use of the spare tire 3. At the same time, the locking part can lock the spare tire mounting seat 1, keeping the spare tire 3 in the first position and preventing the spare tire mounting seat 1 from shaking due to vehicle movement, thereby ensuring driving safety.

[0036] Based on the above overall introduction, specifically, combined with Figure 4 , Figure 7 As shown, the carriage 8 in this embodiment is provided with a mounting bracket 4, which is connected to the inner wall of the carriage 8, thereby providing a stable mounting base for the spare tire mounting seat 1 and the pick-up and drop guide mechanism, so as to ensure the installation stability of the spare tire mounting seat 1 and the pick-up and drop guide mechanism in the carriage 8.

[0037] Specifically, in this embodiment, the mounting bracket 4 is connected to the front panel 801, bottom panel 802, and two side panels 803 of the carriage 8, so that the mounting bracket 4 rests against the front panel 801 of the carriage 8. This allows the spare tire 3 and the loading / unloading guide mechanism to be positioned at the front end of the carriage 8, close to the vehicle's center of gravity, thus preventing the weight of the spare tire 3, spare tire mounting seat 1, and loading / unloading guide mechanism from affecting the vehicle's shape and ensuring vehicle handling. The mounting bracket 4 includes a first crossbeam 401 and a second crossbeam 402 spaced apart along the vertical direction of the vehicle, several longitudinal beams 403 connecting the first crossbeam 401 and the second crossbeam 402, and a connecting beam 4021 mounted on the second crossbeam 402. The first crossbeam 401 is connected to the front panel 801 of the carriage 8, and rearwardly protruding connecting plates 4011 are provided at both ends of the first crossbeam 401.

[0038] Based on this, combined Figure 4 , Figure 6 and Figure 11 As shown, in this embodiment, the spare tire mounting seat 1 is provided with a hinge 103 on the side near the pick-up and drop guide mechanism. The hinge 103 is connected to the longitudinal beam 403 of the mounting frame 4 to ensure that the spare tire mounting seat 1 is stably rotated in the carriage 8 and to ensure the overall stability of the spare tire mounting seat 1.

[0039] Combination Figure 5 , Figure 6 As shown, in some exemplary embodiments, the spare tire mounting base 1 includes a base body 101 with an internal cavity and a frame 102 disposed on one side of the base body 101. The frame 102 is box-shaped with one end open, and the open end of the frame 102 is connected to the base body 101. The frame 102 is provided with mounting holes for mounting the spare tire 3.

[0040] By designing a seat body 101 with an internal cavity, the overall weight of the mounting base is reduced while ensuring the structural strength of the seat body 101. This facilitates the rotation of the mounting base and provides sufficient installation space for the locking part. Simultaneously, a box-shaped frame 102 is provided, with its open end connected to the seat body 101, forming a stable box structure that provides a stable mounting base for the spare tire 3. Furthermore, the hollow interior of the frame 102 further reduces the overall weight of the mounting base.

[0041] In practical implementation, the mounting holes in this embodiment are used to pass through bolts connecting the spare tire 3 to the hub 301, thereby mounting the spare tire 3 onto the frame 102 and fixing the spare tire 3. Meanwhile, the frame 102 in this embodiment is formed by bending a single sheet of material, and the four sides of the box-shaped structure formed by the frame 102 are welded together to ensure the structural strength of the frame 102. Additionally, flanges 1021 are formed at the ends of the four sides near the base body 101. The frame 102 is connected to the base body 101 through the flanges 1021, thereby increasing the connection area between the frame 102 and the base body 101 and further ensuring the installation stability of the frame 102 on the base body 101.

[0042] Combination Figure 4 As shown, in some exemplary embodiments, the spare tire mounting base 1 is provided with a plurality of limiting blocks 1011, which can abut against the wheel hub 301 of the spare tire 3 to limit the radial displacement of the spare tire 3.

[0043] By setting the limiting block 1011, it can abut against the spare tire 3, thereby providing support for the spare tire 3 and restricting the edge part of the spare tire 3 from moving relative to the mounting seat along its own axis, thereby preventing the spare tire 3 from shaking on the spare tire mounting seat 1 and improving the stability of the spare tire 3 installation.

[0044] In specific implementation, the limiting member 701 of this embodiment is constructed as a frustum-shaped structure and is made of a conventional elastic material known to those skilled in the art, such as rubber. This prevents the spare tire 3 from being damaged by a rigid collision with the limiting member 701 when the limiting member 701 abuts against the wheel hub 301. At the same time, it can prevent the spare tire 3 from colliding with the limiting member 701 and causing abnormal noise when the vehicle is in motion.

[0045] Combination Figure 6 , Figure 8 As shown, in some exemplary embodiments, a limiting part 7 is provided between the carriage 8 and the spare tire mounting seat 1, and the limiting part 7 and the locking part are located at the same end of the spare tire mounting seat 1. The limiting part 7 is used to restrict the downward movement of the spare tire mounting seat 1.

[0046] The limiting part 7 provides support for the end of the mounting base away from the hinge structure, preventing the mounting base from sagging due to the weight of the spare tire 3. This avoids interference between the mounting base and other components inside the carriage 8 and prevents the hinge structure from twisting or being damaged due to the mounting base sagging, thus ensuring smooth rotation of the mounting base. It also ensures smooth locking of the locking part.

[0047] In specific implementation, combined with Figure 7As shown, the locking part in this embodiment can be a latch 4012 and a lock body 104 respectively disposed on the mounting bracket 4 and the spare tire mounting seat 1. Specifically, in this embodiment, the latch 4012 is disposed on the first crossbeam 401, and the lock body 104 is disposed in the cavity of the seat body 101. When the spare tire mounting seat 1 is in the first state, the latch 4012 can lock with the lock body 104 to lock the spare tire mounting seat 1 in the first state.

[0048] Of course, the locking structure of this embodiment can also adopt other conventional locking structures known to those skilled in the art. For example, bolts can be used to screw the end of the spare tire mounting seat 1 onto the mounting bracket 4, or ropes can be used to directly tie the spare tire mounting seat 1 to the mounting bracket 4 to achieve locking of the spare tire mounting seat 1 in the first state, so as to prevent the spare tire mounting seat 1 from shaking when the vehicle is in motion, and to prevent the spare tire mounting seat 1 from colliding with the cargo compartment 8 and the goods inside the cargo compartment 8, thereby improving the safety of vehicle operation.

[0049] In addition, combined Figure 8 As shown, the limiting part 7 in this embodiment includes a limiting member 701 disposed at the bottom of the seat body 101 and a limiting seat 702 disposed on the mounting frame 4. When the spare tire mounting seat 1 is in the first state, the limiting member 701 can move with the seat body 101 to above the limiting seat 702 and be supported by the limiting seat 702, thereby providing support for the spare tire mounting seat 1. The longitudinal beam 403 of the mounting frame 4 is provided with a corner bracket 4031, and the limiting seat 702 is disposed on the corner bracket 4031 to ensure the connection strength of the limiting seat 702 on the mounting frame 4 and to ensure the supporting effect of the limiting seat 702.

[0050] Combination Figure 4 , Figure 11 As shown, in some exemplary embodiments, the pick-up and drop-off guiding mechanism includes a guide member 2 disposed in the carriage 8, the guide member 2 having a guide groove 2011, and the guide member 2 being rotatable relative to the carriage 8 and capable of switching between a storage state and a use state. A locking part is provided on the carriage 8 for locking the guide member 2 in the storage state.

[0051] By rotating the guide member 2 onto the carriage 8, it can rest against the side of the carriage 8 in its retracted state. Furthermore, rotating the guide member 2 allows it to be positioned below the spare tire 3. Thus, by switching the state of the guide member 2, the guiding effect on the spare tire 3 is maintained while minimizing the space occupied inside the carriage 8. Simultaneously, the locking mechanism secures the guide member 2 in its retracted state, preventing it from wobbling and colliding with cargo inside the carriage 8 during vehicle operation, and avoiding any abnormal noise.

[0052] Combination Figure 12 , Figure 14As shown, in some exemplary embodiments, the guide 2 is telescopic to adjust the length of the guide groove 2011. By providing a telescopic guide 2 to change the length of the guide groove 2011, the rolling path of the spare tire 3 can be extended, providing long-distance rolling support for the spare tire 3 and ensuring that the rolling path of the spare tire 3 matches the length of the carriage 8, so as to facilitate the removal of the spare tire 3 from the carriage 8.

[0053] Furthermore, when the guide member 2 is in the retracted state, it can be driven to retract, thereby further reducing the space occupied by the guide member 2 in the carriage 8. In particular, when retracted, it reduces the space occupied in the height direction of the carriage 8, so as to facilitate the retraction of the guide member 2 and thus improve the utilization rate of the space in the carriage 8.

[0054] Furthermore, in combination Figure 14 , Figure 15 As shown, in some exemplary embodiments, the guide member 2 includes a plurality of nested guide plates 201, each guide plate 201 having a guide groove 2011 formed thereon. Adjacent guide plates 201 are connected by an insertion part, which includes an insertion post 2021 provided on one guide plate 201 and a sliding groove 202 provided on the other guide plate 201, and the insertion post 2021 can slide along the sliding groove 202 to extend and retract the guide member 2.

[0055] With multiple guide plates 201, each with a guide groove 2011, the continuity of the guide groove 2011 is ensured during the extension and retraction of the guide member 2, guaranteeing that the spare tire 3 can roll along a stable path and thus improving the smoothness of the spare tire 3 loading and unloading process. Simultaneously, the cooperation between the sliding groove 202 and the insertion post 2021 guides the relative sliding between adjacent guide plates 201, providing guidance and limiting effects for the overall extension and retraction of the guide member 2, ensuring the smoothness of the extension and retraction process and facilitating the use of the guide member 2.

[0056] In practical implementation, the guide plate 201 is formed into a "U" shape by bending a single sheet material, thus forming the guide groove 2011. At the same time, the bending and forming process of the guide plate 201 also improves its bending and torsional strength, and enhances the overall structural strength of the guide component 2, thereby ensuring the support effect of the guide component 2 on the spare tire 3 and guaranteeing the stability of the spare tire 3's rolling.

[0057] In addition, the slide groove 202 and the insert post 2021 of this embodiment can be provided on the side wall of the guide groove 2011 to prevent the insert post 2021 from affecting the rolling of the spare tire 3. Of course, the slide groove 202 and the insert post 2021 of this embodiment can also be configured as two separate ones on the two side walls of the guide groove 2011 to ensure the connection stability between the guide plates 201.

[0058] Combination Figures 12 to 16 As shown, in some exemplary embodiments, the locking part includes a mounting groove 5 provided on the carriage 8, and a locking pin 6 slidably disposed within the mounting groove 5. Corresponding to the locking pin 6, the guide member 2 is provided with a locking groove 203. The locking pin 6 can slide from a first position 5011 within the mounting groove 5 to a second position 5021. In the first position 5011, the locking pin 6 slides into the locking groove 203 and is blocked on one side of the guide member 2. In the second position 5021, the locking pin 6 slides out of the locking groove 203.

[0059] With the installation groove 5, locking groove 203, and locking pin 6 configured, when the guide member 2 is in the retracted state, the locking groove 203 can partially overlap with the installation groove 5. At this time, by pushing the locking pin 6 along the installation groove 5 into the locking groove 203, it is blocked on one side of the guide member 2, thus restricting the rotation of the guide member 2 and ensuring the locking effect of the guide member 2. At the same time, locking and unlocking of the guide member 2 can be completed simply by driving the locking pin 6 to slide along the installation groove 5. The operation steps are simple, which can shorten the time of the guide member 2's state switching, thereby improving the operation efficiency of the spare tire 3.

[0060] In practical implementation, since the guide member 2 consists of four guide plates 201, the locking groove 203 in this embodiment is provided on one guide plate 201 near the connecting beam 4021, and the connecting arm 2012 is also provided on the guide plate 201. Obviously, the number of guide members 2 is not limited to the four shown in the figure, and can be adjusted accordingly according to design requirements.

[0061] Understandably, in the retracted state, the top of the guide member 2 is fixed by the locking part, that is, by the locking groove 203 and the locking pin 6, while the bottom of the guide member 2 is hinged to the connecting beam 4021 by the connecting arm 2012. The guide plate 201 closest to the connecting beam 4021 is provided with a connecting arm 2012 for connecting the connecting beam 4021. If the locking groove 203 is provided on other guide plates 201, in the retracted state, the locking force of the locking pin 6 on the locking groove 203 will be transmitted through other guide plates 201 to the guide plate 201 closest to the connecting beam 4021 and provided with the connecting arm 2012, ultimately achieving the locking of the entire guide plate 201.

[0062] However, since there are multiple other guide plates 201 between the guide plate 201 with locking groove 203 and the guide plate 201 with connecting arm 2012, there is no rigid connection between the guide plate 201 with locking groove 203 and the guide plate 201 with connecting arm 2012. When the guide member 2 is in the stored state, there is still a risk of shaking, which makes the locking effect of the guide member 2 poor.

[0063] Therefore, by setting both the locking groove 203 and the connecting arm 2012 on the same guide plate 201, a rigid force transmission path is formed between the locking groove 203 and the connecting arm 2012. When the guide plate 201 is locked, it can constrain other guide plates 201 to prevent the guide member 2 from shaking, thereby further ensuring the locking effect of the guide member 2.

[0064] In addition, in this embodiment, the locking groove 203 is provided on the guide plate 201, that is, on the side wall of the guide groove 2011, and the mounting groove 5 and the locking pin 6 are provided on one side of the longitudinal beam 403 in the mounting frame 4. When the guide member 2 is in the retracted state, the guide groove 2011 can be engaged with the longitudinal beam 403, so that the locking groove 203 and the mounting groove 5 with the second position 5021 partially overlap, to ensure that the locking pin 6 can slide into the locking groove 203.

[0065] In addition, the guide groove 2011 can engage with the longitudinal beam 403. The guide member 2 in the stored state and the projection of the longitudinal beam 403 in the left and right directions of the whole vehicle partially overlap, thereby further reducing the occupation of the longitudinal space of the carriage 8 by the guide member 2 and further saving the space of the carriage 8.

[0066] Based on this, the preferred combination Figure 13 , Figure 16 As shown, the mounting slot 5 in this embodiment includes a first portion 501 and a second portion 502 spaced apart, and a connecting portion 503 disposed between the tops of the first portion 501 and the second portion 502. Both the first portion 501 and the second portion 502 extend along the height direction of the carriage 8, and the bottom of the first portion 501 is lower than the second portion 502. The first position 5011 is located at the bottom of the first portion 501, and the second position 5021 is located at the bottom of the second portion 502.

[0067] With the arrangement of the first part 501, the second part 502, and the connecting part 503, the locking pin 6 needs to rise along the first part 501 or the second part 502 and move laterally along the connecting part 503, thereby moving between the first position 5011 and the second position 5021. Thus, the locking pin 6 is held at the bottom of the first part 501 and the second part 502 by gravity, preventing it from moving due to vehicle bumps during movement and avoiding accidental unlocking of the guide member 2, thereby improving the locking reliability of the locking part. Furthermore, the locking groove 203 coincides with the first part 501.

[0068] Combination Figure 6 , Figure 11 As shown, in some exemplary embodiments, a power assist element 9 is provided between the vehicle compartment 8 and the spare tire mounting seat 1. The power assist element 9 is adapted to apply rotational assistance to the spare tire mounting seat 1 when the spare tire 3 switches from a first state to a second state.

[0069] By incorporating the assist element 9, assistance is provided to the spare tire mounting seat 1 during its rotation, thereby reducing the operational effort required and improving ease of use. Simultaneously, the assist element 9 limits the rotation speed and range of the spare tire mounting seat 1 to prevent excessive rotation speed or range of motion, which could lead to collisions with the user, the carriage 8, or the cargo within the carriage 8, ensuring safety during the switching of the spare tire 3's arrangement.

[0070] In specific implementation, the assisting element 9 of this embodiment can be a conventional assisting element 9 known to those skilled in the art, such as a gas strut, an electric push rod, etc., which can provide assistance when the spare tire mounting seat 1 rotates.

[0071] Specifically, in this embodiment, the assisting element 9 is located below the spare tire mounting base 1, and the two ends of the assisting element 9 are respectively provided with ball sockets. At the same time, both the spare tire mounting base 1 and the mounting bracket 4 are provided with ball heads for ball joint sockets. The ball heads are respectively located at the bottom of the spare tire mounting base 1 and on the side of the second crossbeam 402 of the mounting bracket 4 facing the rear of the vehicle. Thus, it can be ensured that the assisting element 9 has a sufficient range of motion, thereby providing assistance to the spare tire mounting base 1 during the rotation of the spare tire mounting base 1.

[0072] It is worth noting that, regarding the spare tire mounting assembly of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 16 As shown, it may include, for example, an installation mechanism and a pick-and-place guide mechanism provided in the carriage 8.

[0073] The installation mechanism includes a spare tire mounting seat 1 rotatably connected to the carriage 8, and a locking part provided between the spare tire mounting seat 1 and the carriage 8. The locking part can lock the spare tire mounting seat 1 in a first state where it is transversely placed in the carriage 8, and the spare tire mounting seat 1 can be rotated to a second state where it is longitudinally placed in the carriage 8 after being unlocked.

[0074] Furthermore, the spare tire mounting bracket 1 includes a seat body 101 with an internal cavity, and a frame 102 disposed on one side of the seat body 101. The frame 102 is box-shaped with one open end, and the open end of the frame 102 is connected to the seat body 101. The frame 102 has mounting holes for mounting the spare tire 3. The spare tire mounting bracket 1 is provided with a plurality of limiting blocks 1011, which can abut against the wheel hub 301 of the spare tire 3 to limit the radial displacement of the spare tire 3. A limiting part 7 is provided between the vehicle compartment 8 and the spare tire mounting bracket 1, and the limiting part 7 and the locking part are located at the same end of the spare tire mounting bracket 1. The limiting part 7 is used to limit the downward movement of the spare tire mounting bracket 1.

[0075] Additionally, the loading and unloading guide mechanism can be positioned below the spare tire mounting seat 1 in the second state and is suitable for guiding the spare tire 3 to slide into or out of the carriage 8. The loading and unloading guide mechanism includes a guide member 2 disposed in the carriage 8, the guide member 2 having a guide groove 2011, and the guide member 2 being rotatable relative to the carriage 8, switching between a stored state and a used state. A locking part is provided on the carriage 8 to lock the guide member 2 in the stored state.

[0076] Furthermore, the guide member 2 includes multiple nested guide plates 201, each with a guide groove 2011. Adjacent guide plates 201 are connected by an insertion part, which includes a post 2021 on one guide plate 201 and a sliding groove 202 on the other guide plate 201. The post 2021 can slide along the sliding groove 202 to extend and retract the guide member 2. The locking part includes a mounting groove 5 on the carriage 8 and a locking post 6 slidably disposed within the mounting groove 5. Corresponding to the locking post 6, the guide member 2 has a locking groove 203. The locking post 6 can slide from a first position 5011 within the mounting groove 5 to a second position 5021. In the first position 5011, the locking post 6 slides into the locking groove 203 and is blocked on one side of the guide member 2. In the second position 5021, the locking post 6 slides out of the locking groove 203.

[0077] In the preferred embodiment of the above spare tire mounting assembly, the specific configuration and arrangement of the spare tire mounting base 1, guide member 2, locking part, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the spare tire mounting base 1, guide member 2, locking part, etc. can also be referred to the descriptions in the above exemplary embodiments.

[0078] The spare tire mounting assembly of this embodiment adopts the above design. Through the spare tire mounting seat 1 and the pick-and-place guide mechanism, the orientation of the spare tire 3 can be changed by rotating the spare tire mounting seat 1. When the spare tire 3 is in the horizontal first state, space in the vehicle compartment 8 can be saved. Simultaneously, the locking part can lock the spare tire mounting seat 1, keeping the spare tire 3 in the first state and preventing the spare tire mounting seat 1 from shaking due to vehicle movement, thus ensuring driving safety. When the spare tire 3 is in the second state, the removed spare tire 3 can be carried by the pick-and-place guide mechanism, allowing the spare tire 3 to roll along the guide mechanism, replacing the operation of carrying and lifting the spare tire 3. This facilitates the installation and removal of the spare tire 3 in the vehicle compartment 8, improving the ease of use of the spare tire 3.

[0079] An embodiment of the second aspect of this application provides a vehicle having a spare tire mounting assembly as described above.

[0080] In this embodiment, the vehicle can change the orientation of the spare tire 3 by setting up the spare tire mounting assembly, thereby saving space in the compartment 8 while allowing the spare tire 3 to be placed longitudinally and to roll along the pick-up and drop guide mechanism. This replaces the pick-up and drop operation of carrying and lifting the spare tire 3, making it easier to pick up and drop the spare tire 3 in the compartment 8, improving the convenience of using the spare tire 3, and contributing to the improvement of the overall vehicle user experience.

[0081] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
