Description

Technical Field

[0001] The present invention relates to an automobile, and more particularly to a lifting device, an in-vehicle cup holder, and an automobile. Background Art

[0002] An in-vehicle cup holder for placing cups is provided inside an automobile. For example, an in-vehicle cup holder is provided at the passenger-side instrument panel of the automobile, and the in-vehicle cup holder is developing from a fixed depth to an adjustable depth.

[0003] Currently, some in-vehicle cup holders with a lifting function have also appeared on the market. For example, the patent with the application number CN202010030685.X proposes a folding and lifting device for a vehicle. The folding and lifting device for a vehicle includes an outer housing, a lifting tray, a folding assembly, and a synchronous buffer assembly. The outer housing includes a housing bottom, and a lifting tray is movably arranged inside the outer housing. A folding assembly is movably arranged between the lower side of the lifting tray and the upper side of the housing bottom. The folding assembly is composed of two identical side V-shaped folding members symmetrically arranged front and rear. A synchronous buffer assembly is arranged between the lower sides of the two side V-shaped folding members. Each of the two side V-shaped folding members includes a front upper folding strip, a front lower folding strip, a rear upper folding strip, and a rear lower folding strip. A first synchronous rack is fixedly arranged on the rear side of the front lower folding strip, and a second synchronous rack is fixedly arranged on the front side of the rear lower folding strip. The first synchronous rack and the second synchronous rack have the same radius and the same tooth profile and are meshed with each other for transmission. The above folding and lifting device has the following technical problems: When folding is performed using two side V-shaped folding members, synchronization is only carried out using synchronous racks at the lower parts of the two side V-shaped folding members. The lifting tray is hinged to the upper parts of the two side V-shaped folding members, and the structure is not stable. The lifting tray is easily attached to the inner wall of the outer housing, resulting in jamming.

[0004] For another example, the patent with the application number CN202011202028.5 proposes a vehicle-mounted lifting cup holder, which includes: an outer shell; a lifting tray, which is arranged in the outer shell in a liftable manner; a buffer assembly, which is arranged in the outer shell, and the buffer assembly is linked with the lifting tray to slow down the moving speed of the lifting tray; a lifting assembly, which is arranged in the outer shell, and the lifting assembly has an annular connection end, and the annular connection end is in contact connection with the lifting tray to jack up the lifting tray. The above vehicle-mounted lifting cup holder has the following technical problems: The vehicle-mounted lifting cup uses a guiding groove opened on the inner side wall of the cup cylinder to guide the lifting tray through the guiding groove so that the lifting tray moves up and down linearly and stably. When the vehicle-mounted lifting cup holder is in use, the guiding groove is exposed, which is not beautiful; when the vehicle-mounted lifting cup holder is in use, it is inevitable that small items will fall into the guiding groove, which easily causes the mechanism to jam and be damaged; the vehicle-mounted lifting cup holder uses a compression spring as the restoring power of the lifting tray. The compression spring in the vehicle-mounted lifting cup holder is large in volume, high in cost and uneven in power. The closer the lifting tray descends to the bottom, the greater the spring force of the compression spring, and the change range of the spring force of the compression spring is large, resulting in a poor operating feel of the vehicle-mounted lifting cup.

[0029] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention, rather than for limiting the protection scope of the present invention.

[0030] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in its actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0031] Such as Figures 1 to 9A lifting device 1 shown in the figure includes a base 101, a tray 102, a first arm 103, a second arm 104, a third arm 105, a fourth arm 106 and a first stabilizing arm 111; the tray 102 is located above the base 101, and the tray 102 can be lifted relative to the base 101. The lower end of the first arm 103 is hinged to the front of the base 101 through a first hinge structure, and the first arm 103 is arranged obliquely backward from bottom to top. The lower end of the second arm 104 is hinged to the rear of the base 101 through a second hinge structure, and the second arm 104 is arranged obliquely forward from bottom to top. The upper end of the third arm 105 is hinged to the front of the tray 102 through a third hinge structure, and the third arm 105 is arranged obliquely backward from top to bottom. The upper end of the fourth arm 106 is hinged to the rear of the tray 102 through a fourth hinge structure, and the fourth arm 106 is arranged obliquely forward from top to bottom. The upper end of the first arm 103 and the lower end of the third arm 105 are hinged through a fifth hinge structure, and the upper end of the second arm 104 and the lower end of the fourth arm 106 are hinged through a sixth hinge structure.

A first limiting structure is provided between the first stabilizing arm 111 and the base 101, and the first limiting structure limits the first stabilizing arm 111 to only be able to move up and down relative to the base 101.

[0032] Adopting the above technical solution, during the lifting process of the tray 102, the first folding assembly composed of the first arm 103 and the third arm 105 and the second folding assembly composed of the second arm 104 and the fourth arm 106 will both open and fold. The setting of the first folding assembly and the second folding assembly is beneficial to ensuring the stable linear movement of the tray 102. By providing the first stabilizing arm 111 between the first arm 103 and the second arm 104, during the lifting process of the tray 102, the first stabilizing arm 111 moves linearly up and down relative to the base 101. By reasonably setting the connection structures between the first stabilizing arm 111 and the first arm 103 and between the first stabilizing arm 111 and the second arm 104, on the one hand, it can ensure the synchronous rotation of the first arm 103 and the second arm 104, and further ensure the stable linear movement of the tray 102. On the other hand, the first stabilizing arm 111 makes rational use of the layout space between the first arm 103 and the second arm 104, and the layout space requirement of the first stabilizing arm 111 in the up-down direction is small, making the structure of the lifting device 1 more compact.

[0033] In some embodiments, the first hinge structure includes a first hinge shaft 117 fixedly disposed on the upper side of the front portion of the base 101 and a first hinge hole 125 disposed at the lower end portion of the first arm 103. The first hinge hole 125 cooperates with the first hinge shaft 117 to enable the first arm 103 to rotate about the first hinge shaft 117. As a preferred example, for convenient assembly, a first notch for the first hinge shaft 117 to snap into the first hinge hole 125 is provided at the lower end portion of the first arm 103.

[0034] In some embodiments, the second hinge structure includes a second hinge shaft 118 fixedly disposed on the upper side of the rear portion of the base 101 and a second hinge hole 126 disposed at the lower end portion of the second arm 104. The second hinge hole 126 cooperates with the second hinge shaft 118 to enable the second arm 104 to rotate about the second hinge shaft 118. As a preferred example, for convenient assembly, a second notch for the second hinge shaft 118 to snap into the second hinge hole 126 is provided at the lower end portion of the second arm 104.

[0035] In some embodiments, the third hinge structure includes a third hinge shaft 123 fixedly disposed on the lower side of the front portion of the tray 102 and a third hinge hole 127 disposed at the upper end portion of the third arm 105. The third hinge hole 127 cooperates with the third hinge shaft 123 to enable the third arm 105 to rotate about the third hinge shaft 123. As a preferred example, for convenient assembly, a third notch for the third hinge shaft 123 to snap into the third hinge hole 127 is provided at the upper end portion of the third arm 105.

[0036] In some embodiments, the fourth hinge structure includes a fourth hinge shaft 124 fixedly disposed on the lower side of the rear portion of the tray 102 and a fourth hinge hole 128 disposed at the upper end portion of the fourth arm 106. The fourth hinge hole 128 cooperates with the fourth hinge shaft 124 to enable the fourth arm 106 to rotate about the fourth hinge shaft 124. As a preferred example, for convenient assembly, a fourth notch for the fourth hinge shaft 124 to snap into the fourth hinge hole 128 is provided at the upper end portion of the fourth arm 106.

[0037] In some embodiments, the fifth hinge structure includes a fifth hinge shaft 107, a fifth hinge hole 133 disposed at the upper end portion of the first arm 103, and a sixth hinge hole 136 disposed at the lower end portion of the third arm 105. Both the fifth hinge hole 133 and the sixth hinge hole 136 cooperate with the fifth hinge shaft 107 to hinge the first arm 103 and the third arm 105 together.

[0038] In some embodiments, the sixth hinge structure includes a sixth hinge shaft 108, a seventh hinge hole 134 provided at the upper end of the second arm 104, and an eighth hinge hole 137 provided at the lower end of the fourth arm 106. Both the seventh hinge hole 134 and the eighth hinge hole 137 cooperate with the sixth hinge shaft 108 to hinge the second arm 104 and the fourth arm 106 together.

[0039] In some embodiments, a first shaft portion 139 with an axis arranged in the left - right direction is provided at the front end of the first stabilizing arm 111, and a first elongated hole 129 with a length arranged along the length direction of the first arm 103 is provided at the lower part of the first arm 103. The first shaft portion 139 cooperates with the first elongated hole 129 in a slidable and rotatable manner; a second shaft portion 140 with an axis arranged in the left - right direction is provided at the rear end of the first stabilizing arm 111, and a second elongated hole 130 with a length arranged along the length direction of the second arm 104 is provided at the lower part of the second arm 104. The second shaft portion 140 cooperates with the second elongated hole 130 in a slidable and rotatable manner. With the above - mentioned technical solution, the first shaft portion 139 and the first elongated hole 129 constitute a connection structure that can relatively linearly slide and relatively rotate between the front end of the first stabilizing arm 111 and the first arm 103, and the second shaft portion 140 and the second elongated hole 130 constitute a connection structure that can relatively linearly slide and relatively rotate between the rear end of the first stabilizing arm 111 and the second arm 104. During the lifting and lowering of the tray 102, the first shaft portion 139 can slide along the length direction of the first elongated hole 129 and can rotate relative to the first elongated hole 129, and the second shaft portion 140 can slide along the length direction of the second elongated hole 130 and can rotate relative to the second elongated hole 130. Combining with the limiting effect of the first limiting structure on the first stabilizing arm 111, the first arm 103 and the second arm 104 rotate synchronously.

[0040] In some embodiments, the first limiting structure includes a first end limiting structure and a second end limiting structure. The first end limiting structure includes a first guiding block 113 provided at the front end of the first stabilizing arm 111 and a first guiding groove 114 provided on the base 101. The first guiding block 113 cooperates with the first guiding groove 114. The second end limiting structure includes a second guiding block 115 provided at the rear end of the first stabilizing arm 111 and a second guiding groove 116 provided on the base 101. The second guiding block 115 cooperates with the second guiding groove 116. With the above - mentioned technical solution, it is easy to implement the provision of the first guiding groove 114 and the second guiding groove 116 on the base 101 and the provision of the first guiding block 113 and the second guiding block 115 on the first stabilizing arm 111.

[0041] As a specific example, a first guiding block 113 is provided at the end of the first shaft portion 139. The thickness of the first guiding block 113 is not greater than the width of the first elongated hole 129. The length of the first guiding block 113 in the up-and-down direction is not greater than the length of the first elongated hole 129. The lower part of the first guiding block 113 extends downward from the first shaft portion 139. With the above technical solution, during assembly, the first guiding block 113 can pass through the first elongated hole 129, which facilitates the use of an integrally formed structure for the first stabilizing arm 111. After assembly, the first guiding block 113 can play a role in preventing the first shaft portion 139 from disengaging from the first elongated hole 129.

[0042] In some embodiments, a second guiding block 115 is provided at the end of the second shaft portion 140. The thickness of the second guiding block 115 is not greater than the width of the second elongated hole 130. The length of the second guiding block 115 in the up-and-down direction is not greater than the length of the second elongated hole 130. The lower part of the second guiding block 115 extends downward from the second shaft portion 140. With the above technical solution, during assembly, the second guiding block 115 can pass through the second elongated hole 130, which facilitates the use of an integrally formed structure for the first stabilizing arm 111. After assembly, the second guiding block 115 can play a role in preventing the second shaft portion 140 from disengaging from the second elongated hole 130.

[0043] In some embodiments, first guiding blocks 113 are provided on both the left and right sides of the front end of the first stabilizing arm 111. Correspondingly, two first guiding grooves 114 are provided at the front of the base 101, and the two first guiding grooves 114 cooperate with the two first guiding blocks 113 respectively. As a preferred example, each of the two first guiding grooves 114 is formed by two vertical plates fixedly connected to the base 101. A third limiting groove is formed between the two vertical plates enclosing one first guiding groove 114 and the two vertical plates enclosing the other first guiding groove 114. The third limiting groove is used to limit the position of the front end of the first stabilizing arm 111 in the left-and-right direction and the position of the lower end of the first arm 103 in the left-and-right direction. With the above technical solution, on the one hand, the provision of the two first guiding grooves 114 can ensure stable guiding of the front end of the first stabilizing arm 111, which is beneficial to ensuring the stable operation of the lifting device 1. On the other hand, the formation of the third limiting groove between the two first guiding grooves 114 can strengthen the limitation of the first arm 103 and the first stabilizing arm 111, which is also beneficial to ensuring the stable operation of the lifting device 1.

[0044] In some embodiments, second guide blocks 115 are provided on both the left and right sides of the rear end of the first stabilizing arm 111. Correspondingly, two second guide grooves 116 are provided at the rear part of the base 101, and the two second guide grooves 116 cooperate with the two second guide blocks 115 respectively. As a preferred example, each of the two second guide grooves 116 is formed by two vertical plates fixedly connected to the base 101. A fourth limiting groove is formed between the two vertical plates enclosing one second guide groove 116 and the two vertical plates enclosing the other second guide groove 116. The fourth limiting groove is used to limit the position of the rear end of the first stabilizing arm 111 in the left-right direction and the position of the lower end of the second arm 104 in the left-right direction. With the above technical solution, on the one hand, the two second guide grooves 116 are provided to ensure stable guiding of the rear end of the first stabilizing arm 111, which is beneficial to ensuring the stable operation of the lifting device 1. On the other hand, the fourth limiting groove formed between the two second guide grooves 116 can strengthen the limitation of the first arm 103 and the first stabilizing arm 111, which is also beneficial to ensuring the stable operation of the lifting device 1.

[0045] In some embodiments, the lifting device 1 further includes a second stabilizing arm 112. The front end of the second stabilizing arm 112 and the third arm 105 are connected in a manner that allows relative linear sliding and relative rotation. The rear end of the second stabilizing arm 112 and the fourth arm 106 are connected in a manner that allows relative linear sliding and relative rotation. A second limiting structure is provided between the second stabilizing arm 112 and the tray 102, and the second limiting structure limits the second stabilizing arm 112 to be only able to move up and down relative to the tray 102. With the above technical solution, by providing the second stabilizing arm 112 between the third arm 105 and the fourth arm 106, during the lifting process of the tray 102, the second stabilizing arm 112 moves linearly up and down relative to the tray 102. By reasonably setting the connection structures between the second stabilizing arm 112 and the third arm 105 and between the second stabilizing arm 112 and the fourth arm 106, on the one hand, it can ensure the synchronous rotation of the third arm 105 and the fourth arm 106, and further ensure the stable linear movement of the tray 102. On the other hand, the second stabilizing arm 112 makes rational use of the layout space between the third arm 105 and the fourth arm 106. The second stabilizing arm 112 has small layout space requirements in the up-down direction, making the structure of the lifting device 1 more compact. It is precisely because the second stabilizing arm 112 designed in this application has small requirements for the layout space that it provides the possibility to arrange the synchronous structure between the third arm 105 and the fourth arm 106. The synchronous structures used in the in-vehicle lifting cup holders in the prior art are difficult to be arranged between the third arm 105 and the fourth arm 106.

[0046] In some embodiments, a third shaft portion 141 with an axis arranged in the left - right direction is provided at the front end of the second stabilizing arm 112, and a third strip - shaped hole 131 with a length arranged along the length direction of the third arm 105 is provided at the upper part of the third arm 105. The third shaft portion 141 is engaged with the third strip - shaped hole 131 in a slidable and rotatable manner; a fourth shaft portion 142 with an axis arranged in the left - right direction is provided at the rear end of the second stabilizing arm 112, and a fourth strip - shaped hole 132 with a length arranged along the length direction of the fourth arm 106 is provided at the upper part of the fourth arm 106. The fourth shaft portion 142 is engaged with the fourth strip - shaped hole 132 in a slidable and rotatable manner. With the above - mentioned technical solution, the third shaft portion 141 and the third strip - shaped hole 131 form a connection structure that can relatively linearly slide and relatively rotate between the front end of the second stabilizing arm 112 and the third arm 105, and the fourth shaft portion 142 and the fourth strip - shaped hole 132 form a connection structure that can relatively linearly slide and relatively rotate between the rear end of the second stabilizing arm 112 and the fourth arm. During the lifting and lowering of the tray 102, the third shaft portion 141 can slide along the length direction of the third strip - shaped hole 131 and can rotate relative to the third strip - shaped hole 131, and the fourth shaft portion 142 can slide along the length direction of the fourth strip - shaped hole 132 and can rotate relative to the fourth strip - shaped hole 132. Combining with the limiting effect of the second limiting structure on the second stabilizing arm 112, the third arm 105 and the fourth arm 106 rotate synchronously.

[0047] In some embodiments, the second limiting structure includes a third end - limiting structure and a fourth end - limiting structure. The third end - limiting structure includes a third guiding block 119 provided at the front end of the second stabilizing arm 112 and a third guiding groove 120 provided on the tray 102. The third guiding block 119 is engaged with the third guiding groove 120. The fourth end - limiting structure includes a fourth guiding block 121 provided at the rear end of the second stabilizing arm 112 and a fourth guiding groove 122 provided on the tray 102. The fourth guiding block 121 is engaged with the fourth guiding groove 122. With the above - mentioned technical solution, it is easy to implement the provision of the third guiding groove 120 and the fourth guiding groove 122 on the tray 102 and the provision of the third guiding block 119 and the fourth guiding block 121 on the second stabilizing arm 112.

[0048] As a specific example, a third guiding block 119 is provided at the end of the third shaft portion 141. The thickness of the third guiding block 119 is not greater than the width of the third strip - shaped hole 131, the length of the third guiding block 119 in the up - down direction is not greater than the length of the third strip - shaped hole 131, and the lower part of the third guiding block 119 extends downward from the third shaft portion 141. With the above - mentioned technical solution, during assembly, the third guiding block 119 can pass through the third strip - shaped hole 131, which provides convenience for the second stabilizing arm 112 to adopt an integrally formed structure. After assembly, the third guiding block 119 can play a role in preventing the third shaft portion 141 from disengaging from the third strip - shaped hole 131.

[0049] In some embodiments, a fourth guiding block 121 is provided at the end of the fourth shaft portion 142. The thickness of the fourth guiding block 121 is not greater than the width of the fourth elongated hole 132, the length of the fourth guiding block 121 in the up-and-down direction is not greater than the length of the fourth elongated hole 132, and the lower part of the fourth guiding block 121 extends downward beyond the fourth shaft portion 142. With the above technical solution, during assembly, the fourth guiding block 121 can pass through the fourth elongated hole 132, which facilitates the use of an integrally formed structure for the second stabilizing arm 112. After assembly, the fourth guiding block 121 can play a limiting role in preventing the fourth shaft portion 142 from disengaging from the fourth elongated hole 132.

[0050] In some embodiments, third guiding blocks 119 are provided on both the left and right sides of the front end of the second stabilizing arm 112. Correspondingly, two third guiding grooves 120 are provided at the front of the tray 102, and the two third guiding grooves 120 cooperate with the two third guiding blocks 119 respectively. As a preferred example, both of the two third guiding grooves 120 are formed by two vertical plates fixedly connected to the lower side of the tray 102. A fifth limiting groove is formed between the two vertical plates enclosing one third guiding groove 120 and the two vertical plates enclosing the other third guiding groove 120. The fifth limiting groove is used to limit the position of the front end of the second stabilizing arm 112 in the left-and-right direction and the position of the upper end of the third arm 105 in the left-and-right direction. With the above technical solution, on the one hand, the use of two third guiding grooves 120 can ensure stable guiding of the front end of the second stabilizing arm 112, which is beneficial to ensuring the stable operation of the lifting device 1. On the other hand, the formation of the fifth limiting groove between the two third guiding grooves 120 can strengthen the limitation of the third arm 105 and the second stabilizing arm 112, which is also beneficial to ensuring the stable operation of the lifting device 1.

[0051] In some embodiments, fourth guide blocks 121 are provided on both the left and right sides of the rear end of the second stabilizing arm 112. Correspondingly, two fourth guide grooves 122 are provided at the rear of the tray 102, and the two fourth guide grooves 122 cooperate with the two fourth guide blocks 121 respectively. As a preferred example, both of the two fourth guide grooves 122 are formed by two vertical plates fixedly connected to the lower side of the tray 102. A sixth limiting groove is formed between the two vertical plates enclosing one fourth guide groove 122 and the two vertical plates enclosing the other fourth guide groove 122. The sixth limiting groove is used to limit the position of the rear end of the second stabilizing arm 112 in the left-right direction and the position of the upper end of the fourth arm 106 in the left-right direction. By adopting the above technical solution, on the one hand, the use of two fourth guide grooves 122 can ensure the stable guiding of the rear end of the second stabilizing arm 112, which is beneficial to ensuring the stable operation of the lifting device 1. On the other hand, the formation of the sixth limiting groove between the two fourth guide grooves 122 can strengthen the limitation of the fourth arm 106 and the second stabilizing arm 112, which is also beneficial to ensuring the stable operation of the lifting device 1.

[0052] In some embodiments, the first arm 103 and the second arm 104 are arranged in a cross manner. A first avoidance groove for avoiding the second arm 104 is provided on the first arm 103, and the first avoidance groove defines the relative position of the first arm 103 and the second arm 104 in the left-right direction; the third arm 105 and the fourth arm 106 are arranged in a cross manner. A second avoidance groove for avoiding the third arm 105 is provided on the fourth arm 106, and the second avoidance groove defines the relative position of the third arm 105 and the fourth arm 106 in the left-right direction. By adopting the above technical solution, the provision of the first avoidance groove and the second avoidance groove is beneficial to improving the working stability of the lifting device 1.

[0053] In some embodiments, the first folding assembly and the second folding assembly are rotationally symmetric, which can improve the versatility of components and reduce costs.

[0054] In some embodiments, the lifting device 1 further includes an elastic reset member for driving the tray 102 to move upward and reset relative to the base 101. The elastic reset member is disposed between the fifth hinge structure and the sixth hinge structure. In a specific implementation, the elastic reset member is connected between the fifth hinge shaft 107 and the sixth hinge shaft 108, and the elastic reset member is a coil spring 110. With the above technical solution, during the downward movement of the tray 102, the fifth hinge shaft 107 and the sixth hinge shaft 108 move relatively apart, stretching the coil spring 110. The spring force of the coil spring 110 linearly increases. However, at the same time, the included angle between the coil spring 110 and the first arm 103, the second arm 104, the third arm 105, and the fourth arm 106 becomes smaller, and the proportion of the actual reset force received by the tray 102 relative to the spring force generated by the stretching of the coil spring 110 becomes smaller. Similarly, during the upward movement of the tray 102, the fifth hinge shaft 107 and the sixth hinge shaft 108 move relatively closer, the spring force of the coil spring 110 linearly decreases, but at the same time, the included angle between the coil spring 110 and the first arm 103, the second arm 104, the third arm 105, and the fourth arm 106 becomes larger, and the proportion of the actual reset force received by the tray 102 relative to the spring force generated by the stretching of the coil spring 110 becomes larger, making the operating force more stable during the entire lifting process of the tray 102 and facilitating ensuring the use feel.

[0055] In some embodiments, damping members 109 are provided at both the fifth hinge structure and the sixth hinge structure. The damping members 109 are used to provide damping during the folding and unfolding processes of the first folding assembly and the second folding assembly, which is beneficial to improving the use feel. In a specific implementation, the two damping members 109 can be respectively sleeved on the fifth hinge shaft 107 and the sixth hinge shaft 108. As a specific example, a first receiving groove 135 for cooperating with the damping member 109 is provided at the upper end of the first arm 103, and a second receiving groove 138 for cooperating with the damping member 109 is provided at the lower end of the fourth arm 106.

[0056] The present invention also proposes a vehicle cup holder, which includes a housing 2 and the lifting device 1 described in any one of the above. The housing 2 surrounds the periphery of the lifting device 1. The base 101 is connected to the housing 2, and the tray 102 cooperates with the housing 2. The tray 102 can be lifted. After the tray 102 descends, the tray 102 and the housing 2 enclose a receiving cavity 3 for placing articles (such as water cups).

[0057] In some embodiments, the housing 2 is formed by connecting two semi-cylindrical tubes 201. The structures of the two semi-cylindrical tubes 201 are the same. On both sides of the semi-cylindrical tube 201 in the circumferential direction, a first flange 202 and a second flange 205 are respectively provided. A jack 203 is provided on the first flange 202. A clamping block 204 is provided on the outer wall of the semi-cylindrical tube 201. A tongue 206 is provided on the second flange 205. A clamping groove 207 is provided on the tongue 206. The tongue 206 on one semi-cylindrical tube 201 passes through the jack 203 on the other semi-cylindrical tube 201 and is clamped with the clamping block 204 on the other semi-cylindrical tube 201 through the clamping groove 207, so as to fixedly connect the two semi-cylindrical tubes 201 together. By adopting the above technical solution, it has the characteristics of easy assembly and high universality of components.

[0058] In some embodiments, a support surface for upwardly supporting the base 101 is provided at the lower end of the housing 2. A fixed connection structure, such as a clamping structure, can also be provided between the base 101 and the housing 2.

[0059] The present invention also proposes an automobile, including the above-mentioned vehicle-mounted cup holder.

[0060] Compared with the prior art, by providing two stabilizing arms, the present invention realizes the synchronous movement of the first arm 103, the second arm 104, the third arm 105 and the fourth arm 106, and can ensure the stable up-and-down linear movement of the tray 102. It is not necessary to provide a guide groove on the inner wall of the housing 2, which improves the overall aesthetics of the vehicle-mounted cup holder and reduces the risk of foreign objects falling into the guide groove and causing the lifting device to fail. The combined use and ingenious arrangement of the spiral spring 110 and the damping member 109 make the depth adjustment force of the vehicle-mounted cup holder more uniform, and the return process is automatic, with flexible and simple operation and convenient use. The structures of the components are reasonably set, which improves the universality of the components. The same components can be reused, reducing costs. The structure of the stabilizing arms is reasonably set, and the layout space of the stabilizing arms is small, which can avoid occupying the external space of the housing 2, providing a basis for setting two stabilizing arms in the vehicle-mounted cup holder and being beneficial to further improving the stability of the vehicle-mounted cup holder.
