[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The seat 100 and the vehicle provided in the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] like Figure 1-Figure 4 As shown, the seat 100 according to the first embodiment of the utility model includes: a mounting seat 1, a first mounting member 2, a second mounting member 3, a plurality of linkage shafts 4, a seat body 5 and a driving member 6.

[0039] The first mounting member 2 and the second mounting member 3 are symmetrically arranged and spaced apart along the first direction X of the seat 100, the seat body 5 is fixedly connected to the first mounting member 2 and the second mounting member 3, and a plurality of linkage shafts 4 are arranged in parallel and are rotatably connected between the first mounting member 2 and the second mounting member 3. Specifically, Figure 1 As shown, along the first direction X of the seat 100 (i.e., the width direction of the seat 100), the first mounting member 2 and the second mounting member 3 are symmetrically arranged and spaced apart. Furthermore, a plurality of parallel linkage shafts 4 are connected between the first mounting member 2 and the second mounting member 3. For example, the number of the parallel linkage shafts 4 between the first mounting member 2 and the second mounting member 3 can be 2, 3, 4, or 5, which can be arranged according to actual needs and are not specifically limited here. Moreover, each linkage shaft 4 can be rotatable relative to the first mounting member 2 and the second mounting member 3. That is to say, each linkage shaft 4 can be rotatably connected between the first mounting member 2 and the second mounting member 3. For example, the linkage shaft 4 can be connected to the first mounting member 2 and the second mounting member 3 by means of expansion tubes. Of course, the linkage shaft 4 can also adopt other rotational connection methods, which are not specifically limited this time.

[0040] Further, each linkage shaft 4 is provided with at least one linkage member 7, wherein one end of each linkage member 7 is fixedly connected to the linkage shaft 4, and the other end is rotatably connected to the mounting seat 1, that is, each linkage shaft 4 is provided with one or more linkage members 7, for example, the number of linkage members 7 provided to each linkage shaft 4 can be 1, 2, 3, 4, 5, which is provided according to actual needs and is not specifically limited here. Among them, one end of each linkage member 7 is fixedly connected to the linkage shaft 4, and the other end is rotatably connected to the mounting seat 1, so that all linkage shafts 4 and all linkage members 7 can form a multi-link linkage system.

[0041] Further, the driving member 6 is fixed to the mounting seat 1 and is transmission-connected with one of the multiple linkage members 7, that is, the driving member 6 can be transmission-connected with any linkage member 7 arranged on the linkage shaft 4. Since all the linkage shafts 4 and all the linkage members 7 constitute a multi-link linkage system, when the driving member 6 drives one of the linkage members 7 to rotate relative to the mounting seat 1, the linkage member 7 can drive the remaining linkage members 7 to rotate relative to the mounting seat 1 through multiple parallel linkage shafts 4, and then drive the seat body 5 to move upward or downward through the first mounting member 2 and the second mounting member 3 under the drive of the multiple linkage shafts 4, that is, the driving member 6 can drive the linkage member 7 to rotate to drive the seat body 5 to move upward or downward. It can be understood that when the driving member 6 drives the seat body 5 to move to a certain position, if the driving member 6 stops driving, the multi-link linkage system stops moving, and the driving member 6 acts as a supporting member at this time, that is, the driving member 6 has a supporting function for supporting the first mounting member 2, the second mounting member 3, multiple linkage shafts 4, multiple linkage members 7 and the seat body 5.

[0042] It should be noted that, under normal circumstances, the durability of the seat 100 can meet the daily use of passengers. However, in special circumstances, such as failure of the driving component 6 (failure of the electric power system) or detachment of the driving component 6 from the mounting seat 1, the linkage component 7 loses the support and drive of the driving component 6, and the linkage component 7 and the linkage shaft 4 will collapse downward together with the seat body 5, making it impossible for passengers to drive normally.

[0043] Based on this, the mounting seat 1 of the present application has at least one limiting portion 11 arranged corresponding to the linkage member 7, and the limiting portion 11 is suitable for abutting and limiting the linkage member 7 to limit the downward movement of the seat body 5. That is to say, at least one limiting portion 11 is provided on the mounting seat 1, and the limiting portion 11 is arranged corresponding to the linkage member 7. When a plurality of limiting portions 11 are provided on the mounting seat 1, the plurality of limiting portions 11 correspond one-to-one to the plurality of linkage members 7. For example, when two limiting portions 11 are provided on the mounting seat 1, the two limiting portions 11 correspond one-to-one to any two of the plurality of linkage members 7. When three limiting portions 11 are provided on the mounting seat 1, the two limiting portions 11 correspond one-to-one to any three of the plurality of linkage members 7, and so on. No detailed examples are given here.

[0044] Furthermore, when the seat body 5 collapses downward due to loss of support, for example, when the seat body 5 collapses downward due to loss of support caused by failure of the electric power system or a malfunction of the linkage system, the limit portion 11 can abut against the linkage member 7 to limit the rotation of the linkage member 7. It can be understood that the limit portion 11 can be set as a limit groove, a limit protrusion or other limit structure, and the abutment limit contact can be point contact, line contact or surface contact, as long as the linkage member 7 can be limited to rotate downward. Such a setting can fix the seat body 5 in a safe position, prevent the seat body 5 from continuing to collapse downward, ensure the safety of passengers' driving, and there is no need to invest new resources to enhance the strength and durability of each system of the seat 100, which is conducive to reducing development costs.

[0045] According to the seat 100 of the embodiment of the utility model, the seat 100 is provided with a corresponding limiting portion 11 on the mounting seat 1. When the seat body 5 collapses downward due to loss of support, the limiting portion 11 can abut against the linkage member 7 for limiting, thereby limiting the rotation of the linkage member 7 and fixing the seat body 5 in a safe position to prevent the seat body 5 from continuing to collapse downward, thereby ensuring safe driving for passengers. There is no need to invest new resources to enhance the strength and durability of each system of the seat 100, which is conducive to reducing development costs.

[0046] In some embodiments of the present invention, Figure 1 As shown, the mounting seat 1 has a first support member 12 and a second support member 13. The first support member 12 and the first mounting member 2 are correspondingly arranged and spaced apart along the second direction Y of the seat 100. The second support member 13 and the second mounting member 3 are correspondingly arranged and spaced apart along the second direction Y of the seat 100. The first support member 12 and / or the second support member 13 have at least one limiting portion 11 suitable for abutting and limiting with the linkage member 7.

[0047] Specifically, the first support member 12 and the second support member 13 are symmetrically arranged and spaced apart along the first direction X, the first support member 12 and the first mounting member 2 are arranged correspondingly, and the first support member 12 and the first mounting member 2 are spaced apart along the second direction Y of the seat 100. Similarly, the second support member 13 and the second mounting member 3 are arranged correspondingly, and the second support member 13 and the second mounting member 3 are spaced apart along the second direction Y of the seat 100. That is to say, the first mounting member 2 is located directly above the first support member 12, and the second mounting member 3 is located directly above the second support member 13. Further, the first support member 12 and / or the second support member 13 has at least one limiting portion 11 suitable for abutting and limiting with the linkage member 7. For example, at least one limiting portion 11 is provided on the first support member 12, and the second support member 13 is not provided with the limiting portion 11, or at least one limiting portion 11 is provided on the second support member 13, and the first support member 12 is not provided with the limiting portion 11, or at least one limiting portion 11 is provided on the first support member 12, and at least one limiting portion 11 is provided on the second support member 13. The specific setting is based on actual needs and is not specifically limited at this time. It can be understood that since all the linkage shafts 4 and all the linkage members 7 together constitute a multi-link linkage system, when one of the linkage shafts 4 is restricted from rotating, the multi-link linkage system stops moving, so one limiting portion 11 can meet the limiting requirement. However, by providing multiple limiting portions 11, the limiting strength can be improved, and damage to a single limiting portion 11 due to excessive force can be avoided, which is beneficial to improving the safety of the seat 100.

[0048] In some embodiments of the present invention, Figure 1-Figure 4 As shown, multiple linkage shafts 4 include a first linkage shaft 41 and a second linkage shaft 42. The first linkage shaft 41 is correspondingly provided with a first linkage member 71 and a second linkage member 72. One end of the first linkage member 71 is fixedly connected to the first linkage shaft 41, and the other end is rotatably connected to the first support member 12. One end of the second linkage member 72 is fixedly connected to the first linkage shaft 41, and the other end is rotatably connected to the second support member 13. The second linkage shaft 42 is correspondingly provided with a third linkage member 73 and a fourth linkage member 74. One end of the third linkage member 73 is fixedly connected to the second linkage shaft 42, and the other end is rotatably connected to the first support member 12. One end of the fourth linkage member 74 is fixedly connected to the second linkage shaft 42, and the other end is rotatably connected to the second support member 13.

[0049] Specifically, if Figure 1As shown, along the first direction X, the first linkage shaft 41 and the second linkage shaft 42 are arranged in parallel between the first mounting member 2 and the second mounting member 3 of the seat 100, and the first linkage shaft 41 and the second linkage shaft 42 are rotatable relative to the first mounting member 2 and the second mounting member 3. Further, the first linkage shaft 41 is correspondingly provided with a first linkage member 71 and a second linkage member 72, and the first linkage member 71 and the second linkage member 72 are both constructed as a plate-like structure, and can also be constructed as a rod-like structure, and are specifically arranged according to actual conditions. The first linkage member 71 and the second linkage member 72 are respectively arranged at both ends of the first linkage shaft 41 and are parallel to each other, wherein one end of the first linkage member 71 is fixedly connected to the first linkage shaft 41, and the fixed connection method includes but is not limited to welding, etc., the other end of the first linkage member 71 is rotatably connected to the first support member 12, and one end of the second linkage member 72 is fixedly connected to the first linkage shaft 41, and the fixed connection method includes but is not limited to welding, etc., and the other end of the second linkage member 72 is rotatably connected to the second support member 13; further, the second linkage shaft 42 is correspondingly provided with a third linkage member 73 and a fourth linkage member 74. 4. The third linkage member 73 and the fourth linkage member 74 are both constructed as a plate-like structure, or as a rod-like structure, and are specifically arranged according to actual conditions. The third linkage member 73 and the fourth linkage member 74 are respectively arranged at both ends of the second linkage shaft 42 and are parallel to each other, wherein one end of the third linkage member 73 is fixedly connected to the second linkage shaft 42, and the fixed connection method includes but is not limited to welding, etc., the other end of the third linkage member 73 is rotatably connected to the first support member 12, one end of the fourth linkage member 74 is fixedly connected to the second linkage shaft 42, and the fixed connection method includes but is not limited to welding, etc., the other end of the fourth linkage member 74 is rotatably connected to the second support member 13, so that the first linkage shaft 41, the second linkage shaft 42, the first linkage member 71, the second linkage member 72, the third linkage member 73, and the fourth linkage member 74 form a multi-link linkage system.

[0050] Further, refer to Figure 2As shown, the driving member 6 is transmission-connected with the first linkage member 71. Of course, the driving member 6 can also be transmission-connected with any one of the second linkage member 72, the third linkage member 73, and the fourth linkage member 74. The present application only takes the transmission connection between the driving member 6 and the first linkage member 71 as an example for explanation, wherein the rotation connection position between the first linkage member 71 and the first support member 12 acts as a fulcrum, and the transmission connection position between the driving member 6 and the first linkage member 71 is located at the lower side of the fulcrum. In this way, the driving member 6 can drive the first linkage member 71 to rotate relative to the first support member 12. The linkage shaft 42, the first linkage member 71, the second linkage member 72, the third linkage member 73, and the fourth linkage member 74 form a multi-link linkage system. When the driving member 6 drives the first linkage member 71 to rotate counterclockwise, the first linkage member 71 can drive the second linkage member 72, the third linkage member 73, and the fourth linkage member 74 to rotate through the first linkage shaft 41 and the second linkage shaft 42, and then drive the seat body 5 to move upward or downward through the first mounting member 2 and the second mounting member 3 under the drive of the first linkage shaft 41 and the second linkage shaft 42, thereby realizing the up and down adjustment function of the seat 100. When the driving member 6 drives the seat body 5 to move to a certain position, if the driving member 6 stops driving, the multi-link linkage system stops moving, and the driving member 6 acts as a supporting member at this time, that is, the driving member 6 has a supporting function for supporting the first mounting member 2, the second mounting member 3, the multi-link linkage system and the seat body 5. Generally, the durability of the seat 100 can meet the daily use of passengers. However, in special circumstances, for example, the driving component 6 fails (the electric power system fails) or the driving component 6 falls off the mounting seat 1, causing the linkage component 7 to lose the support and drive of the driving component 6. The linkage component 7 and the linkage shaft 4 will collapse downward together with the seat body 5, making it impossible for passengers to drive normally.

[0051] Based on this, in some embodiments of the present application, the first support member 12 and / or the second support member 13 has at least one limiting portion 11. As a specific example, the first support member 12 is respectively provided with two limiting portions 11 corresponding to the first linkage member 71 and the third linkage member 73, and the second support member 13 is respectively provided with two limiting portions 11 corresponding to the second linkage member 72 and the fourth linkage member 74. Figure 2 and Figure 3As shown, the limiting portion 11 is constructed as a limiting plate, which can abut against the corresponding linkage member 7. When the seat body 5 collapses downward due to loss of support, the four limiting portions 11 can respectively abut against the first linkage member 71, the second linkage member 72, the third linkage member 73, and the fourth linkage member 74 to limit the rotation of the linkage member 7, thereby fixing the seat body 5 in a safe position to prevent the seat body 5 from continuing to collapse downward, ensuring safe driving for passengers. At the same time, the four limiting portions 11 can increase the limiting strength to avoid damage to a single limiting portion 11 due to excessive force, which is beneficial to further improve the safety of the seat 100.

[0052] In some embodiments of the present invention, Figure 1 As shown, the mounting base 1 further includes: a connecting member 14, which is fixedly installed between the first support member 12 and the second support member 13. Specifically, the first support member 12 and the second support member 13 are provided with the connecting member 14, and both ends of the connecting member 14 are respectively fixedly connected to the first support member 12 and the second support member 13, and the fixed connection method includes but is not limited to welding, etc., so that the first support member 12 and the second support member 13 are connected as a whole, which is conducive to improving the strength of the mounting base 1.

[0053] In some embodiments of the present invention, Figure 1 As shown, the seat 100 further includes: a fixed bracket 8, and the driving member 6 is fixedly mounted on the connecting member 14 by fixing. Specifically, the driving member 6 is fixedly mounted on the fixed bracket 8, and the fixed bracket 8 can be fixedly mounted on the connecting member 14, or fixedly mounted on the first supporting member 12 or the second supporting member 13. The fixed bracket 8 is conducive to improving the installation strength of the driving member 6, thereby improving the stability of the adjustment of the seat 100.

[0054] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the seat 100 further includes: a transmission member 9, one end of which is fixedly connected to one of the plurality of linkage members 7, and the other end of which is transmission-connected to the driving member 6, and the driving member 6 is suitable for driving the transmission member 9 to drive the linkage member 7 to rotate, so as to move the seat body 5 upward or downward. Specifically, the transmission member 9 is transmission-connected between the driving member 6 and the first linkage member 71 as an example for explanation, wherein the first linkage member 71 and the first support member 12 are rotationally connected at a position that serves as a fulcrum, one end of the transmission member 9 is fixedly connected to the first linkage member 71 through a connecting bolt and is located at the lower side of the fulcrum, and the other end of the transmission member 9 is transmission-connected to the driving member 6, and the driving member 6 is used to drive the first linkage member 71 to rotate through the transmission member 9, so that the transmission member 9 can realize indirect transmission between the driving member 6 and the first linkage member 71, which is conducive to meeting the layout requirements of different installation structures.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the transmission member 9 has a threaded tube 91, the driving member 6 is a driving motor, and the lead screw of the driving motor is passed through the threaded tube 91 and is in driving connection with the threaded tube 91. Specifically, the driving member 6 can be constructed as a driving motor, and the driving motor is used to drive the lead screw to rotate. The transmission member 9 is provided with a threaded tube 91 assembled with the lead screw, as shown in FIG. Figure 2 As shown, when the driving motor drives the lead screw to rotate, the lead screw and the threaded tube 91 can convert the rotation of the lead screw into the front-rear relative movement of the transmission member 9 and the lead screw, and then drive the first linkage member 71 to rotate through the transmission member 9. Since the lead screw and the threaded rod have good movement stability, it is beneficial to improve the transmission stability of the transmission member 9, thereby improving the adjustment stability of the seat 100.

[0056] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the seat 100 further includes: a spring retaining ring 10 , which is arranged on the lead screw, and the spring retaining ring 10 is suitable for abutting against the threaded tube 91 to limit the movement of the threaded tube 91 .

[0057] Specifically, if Figure 2 As shown, the spring retaining ring 10 is arranged at the rear end of the lead screw (i.e., away from the connection position between the drive motor and the lead screw), and after the lead screw is inserted into the threaded tube 91, when the drive motor is used to drive the lead screw to rotate, the spring retaining ring 10 can abut against the rear end of the threaded tube 91 to limit the transmission member 9 from continuing to move backward. It should be noted that a plastic retaining ring with a buffering effect can be installed between the spring retaining ring 10 and the threaded tube 91. When the spring retaining ring 10 fails, the threaded tube 91 cracks, and the fixed bracket 8 of the driving member 6 is welded, the limiting plate can abut against the corresponding linkage member 7, thereby limiting the rotation of the linkage member 7, fixing the seat body 5 in a safe position, preventing the seat body 5 from continuing to collapse downward, and ensuring the safety of passengers.

[0058] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the seat 100 further includes: a rivet 20, and each linkage shaft 4 is rotatably connected to the mounting seat 1 through the rivet 20. That is, taking the first linkage 71, the second linkage 72, the third linkage 73, and the fourth linkage 74 as examples for explanation, the first linkage 71 and the third linkage 73 are rotatably connected to the first support member 12 through the rivet 20, and the second linkage 72 and the fourth linkage 74 are rotatably connected to the second support member 13 through the rivet 20. The rivet 20 can be constructed as a rivet nail. With such a configuration, the assembly process is simple, and certain rotation and support requirements can be met, and the cost is low.

[0059] The vehicle according to the second aspect of the present invention comprises the seat 100 according to the first aspect of the present invention.

[0060] According to the vehicle of the embodiment of the utility model, by providing the above-mentioned seat 100, the seat 100 is provided with a corresponding limiting portion 11 on the mounting seat 1. When the seat body 5 collapses downward due to loss of support, the limiting portion 11 can abut against the linkage member 7 for limiting, thereby limiting the rotation of the linkage member 7, fixing the seat body 5 in a safe position, preventing the seat body 5 from continuing to collapse downward, ensuring safe driving for passengers, and eliminating the need to invest new resources to enhance the strength and durability of each system of the seat 100, which is conducive to reducing development costs.
