[0039] Please refer to Figure 1 , the embodiment of the present application provides a height support device 100. The height support device 100 can be a computer desk, a dining table, a desk, a tea table, a laptop stand, etc.

[0040] The height support device 100 includes a support plate 130 and support legs 110 . The support legs 110 can be used to support the support plate 130 .

[0041] The support plate 130 may be a flat plate, or a drawer may be provided on the support plate 130 , or the support plate 130 may have other structures.

[0042] In some embodiments, the height support device 100 can be a laptop stand to flexibly adjust the height of the support plate 130 relative to the placement location to meet different user needs. The placement location can be the ground, a desk, a bed, or other locations. For ease of description, the following explanation uses the ground as an example.

[0043] For example, the support legs 110 may be retractable, so that the length of the support legs 110 can be flexibly adjusted to flexibly adjust the height of the support plate 130 relative to the ground.

[0044] In some embodiments, the number of the support legs 110 may be one or more. When there are more than one support legs 110 , the multiple support legs 110 can support the support plate 130 more stably.

[0045] Here, a plurality may refer to two or more than two. For example, a plurality of support legs 110 may refer to two support legs 110 , three support legs 110 , four support legs 110 or any other number of support legs 110 .

[0046] For ease of description, the following embodiment will be explained by taking one supporting leg 110 as an example.

[0047] In some embodiments, the support leg 110 has a length direction (eg Figure 1 The length direction may be the extension direction of the support leg 110.

[0048] See also Figures 2 to 4 In some embodiments, the support leg 110 includes a first support member 111 , a second support member 113 and an elastic positioning member 115 .

[0049] The second support member 113 is slidably connected to the first support member 111 along the length direction. The second support member 113 can slide relative to the first support member 111 to adjust the length of the support leg 110, thereby facilitating flexible adjustment of the height of the support plate 130.

[0050] It can be understood that the first support member 111 can also slide relative to the second support member 113 along the length direction.

[0051] The first support member 111 can be connected to the support plate 130, so that the height support device 100 can be placed on the ground through the second support member 113, or the second support member 113 can be connected to the support plate 130, so that the height support device 100 can be placed on the ground through the first support member 111. For the convenience of description, in the following embodiments, the case where the second support member 113 is connected to the support plate 130 is taken as an example for explanation.

[0052] The first support member 111 is provided with at least two positioning holes 1111 along the length direction, and the at least two positioning holes 1111 can be distributed at intervals along the length direction.

[0053] The at least two positioning holes 1111 can refer to two positioning holes 1111, three positioning holes 1111, four positioning holes 1111 or other numbers of positioning holes 1111. For the convenience of description, in the following embodiments, the case of three positioning holes 1111 is taken as an example for explanation, and the three positioning holes 1111 are respectively named the first positioning hole 1112, the second positioning hole 1113 and the third positioning hole 1114.

[0054] The elastic positioning member 115 can be selectively clamped in one of the at least two positioning holes 1111 for adjusting the fixed position of the second support member 113 relative to the first support member 111, and the elastic positioning member 115 can also be elastically deformed to disengage from the positioning hole 1111. In this way, the elastic positioning member 115 can be clamped in different positioning holes 1111, and the elastic positioning member 115 can also be elastically deformed to disengage from the positioning hole 1111, so as to flexibly adjust the position of the second support member 113 relative to the first support member 111, flexibly adjust the length of the support leg 110, and flexibly adjust the height of the support plate 130 relative to the placement position.

[0055] As an example, the elastic positioning member 115 can be clamped in the first positioning hole 1112. At this time, the second support member 113 is fixed to the first support member 111, and the support leg 110 can stably support the support plate 130, as Figure 3 shown. When the elastic positioning member 115 is elastically deformed by force, the elastic positioning member 115 can disengage from the first positioning hole 1112, as Figure 4 shown. At this time, the second support member 113 can slide relative to the first support member 111, and the elastic positioning member 115 slides synchronously with the second support member 113 relative to the first support member 111. When the elastic positioning member 115 is clamped in the second positioning hole 1113, the second support member 113 is fixed to the first support member 111 again, as Figure 5 shown. When the elastic positioning member 115 is elastically deformed by force again to disengage from the second positioning hole 1113, the second support member 113 can slide relative to the first support member 111 again, and the elastic positioning member 115 can slide to be clamped in the first positioning hole 1112 or the third positioning hole 1114.

[0056] The elastic positioning member 115 and the second support member 113 are integrally formed, thereby reducing the number of components in the support leg 110, simplifying the assembly steps for the elastic positioning member 115, reducing the assembly time and cost of the support leg 110, and simplifying the structure of the support leg 110. Furthermore, the integral design of the elastic positioning member 115 and the second support member 113 prevents the elastic positioning member 115 from being missed or lost during packaging and transportation.

[0057] As an example, the second support member 113 and the elastic positioning member 115 may be plastic parts, which are integrally formed by injection molding.

[0058] See also Figures 2 to 4 In some embodiments, the first support member 111 may include an inner circumferential surface 1115, which may enclose a sliding channel 1116 that passes through the first support member 111 along the length direction. For example, the first support member 111 may have an annular columnar structure.

[0059] The positioning hole 1111 may be connected to the sliding channel 1116 , that is, the positioning hole 1111 may be provided on the peripheral wall of the first support member 111 and connected to the sliding channel 1116 .

[0060] The second support member 113 is slidably located in the sliding channel 1116. It can be understood that the elastic positioning member 115 can also slide in the sliding channel 1116. The sliding of the second support member 113 drives the elastic positioning member 115 to slide, so that the elastic positioning member 115 can be clamped in different positioning holes 1111.

[0061] Specifically, the elastic positioning member 115 can include a first state and a second state. When the elastic positioning member 115 is in the first state (i.e., the natural state), the elastic positioning member 115 can be clamped in one of the positioning holes 1111 to fix the second support member 113 to the first support member 111. In the first state, the elastic positioning member 115 is always clamped in the positioning hole 111 when it is not subjected to a sufficiently large external force, thereby preventing the first support member 111 and the second support member 113 from sliding relative to each other. Figure 3 and Figure 5 When the elastic positioning member 115 is in the second state (elastic deformation state), the elastic positioning member 115 is released from the positioning hole 111 by elastic deformation and is located in the sliding channel 1116. As the second support member 113 drives the elastic positioning member 115 to slide in the sliding channel 1116, the elastic positioning member 115 will first abut against the inner circumference 1115 of the first support member 111, as shown in FIG. Figure 4As shown, until the elastic positioning member 115 is engaged in another positioning hole 111, the second support member 113 stops sliding relative to the first support member 111, so as to realize the height adjustment of the support leg 110, as Figure 5 shown.

[0062] The shape of the second support member 113 can be adapted to the sliding channel 1116, so that the second support member 113 can slide within the sliding channel 1116. For example, when the sliding channel 1116 is a circular channel, the second support member 113 can adopt a cylindrical structure.

[0063] Please refer to Figure 4 , in some embodiments, the first support member 111 may include opposite first end face 1117 and second end face 1118, and the first end face 1117 and the second end face 1118 are located at both ends of the first support member 111 along the length direction.

[0064] The second support member 113 may include opposite third end face 1132 and fourth end face 1133, and the third end face 1132 and the fourth end face 1133 are located at both ends of the second support member 113 along the length direction.

[0065] As an example, the length direction may include opposite first direction X and second direction Y. The first end face 1117 may be located at one end of the first support member 111 facing the first direction X, and the second end face 1118 may be located at one end of the first support member 111 facing the second direction Y. The third end face 1132 may be located at one end of the second support member 113 facing the first direction X, and the fourth end face 1133 may be located at one end of the second support member 113 facing the second direction Y. [[ID=1۸]]

[0066] Please refer to Figures 2 to 4 , in some embodiments, the second support member 113 may be provided with a mounting hole 1134, and the elastic positioning member 115 may be disposed in the mounting hole 1134, and the mounting hole 1134 may provide a space for elastic deformation of the elastic positioning member 115.

[0067] As an example, the second support member 113 may be provided with a hollow channel extending along the length direction, and the mounting hole 1134 may be disposed on the peripheral wall of the second support member 113 and communicate with the hollow channel to provide a space for elastic deformation of the elastic positioning member 115.

[0068] Among them, the shape of the mounting hole 1134 can be set in various ways. For example, the mounting hole 1134 can adopt a circular hole, an oval hole, a polygonal hole or other shaped holes.

[0069] In some embodiments, the elastic positioning member 115 may include an elastic portion 1151 and a positioning portion 1152.

[0070] Among them, the elastic part 1151 can be located within the mounting hole 1111 and connected to the hole wall of the mounting hole 1111; one side of the elastic part 1151 away from the hole wall of the mounting hole 1111 has a free end, and the positioning part 1152 can protrude from the free end. The positioning part 1152 can be clamped in one of at least two positioning holes 1111 to adjust the fixed position of the second support member 113 relative to the first support member 111.

[0071] For example, the elastic part 1151 is generally in a strip structure. One end of the elastic part 1151 is connected to the hole wall of the mounting hole 1111, and the other end of the elastic part 1151 can be the free end.

[0072] The elastic part 1151 is configured to elastically deform along the axial direction of the mounting hole 1111. The elastic deformation of the elastic part 1151 can drive the positioning part 1152 to move away from the positioning hole 1111 to disengage from the positioning hole 1111, so that the second support member 113 can slide relative to the first support member 111, so that the positioning part 1152 can be clamped in other positioning holes 1111, so that the position of the second support member 113 relative to the first support member 111 can be flexibly adjusted.

[0073] For example, when the elastic part 1151 is subjected to a force, the elastic deformation generated by the elastic part 1151 bends towards the hollow channel, thereby driving the positioning part 1152 to move away from the positioning hole 1111 to disengage from the positioning hole 1111; when the positioning part 1152 slides in the sliding channel 1116 to the next positioning hole 1111, the elastic part 115 generates an elastic restoring force to drive the positioning part 1152 to move towards the positioning hole 1111 to be clamped in the positioning hole 1111.

[0074] In some embodiments, the mounting hole 1134 can be a rectangular hole. The inner wall surface of the rectangular hole can include a first surface, a second surface, a third surface, and a fourth surface that are sequentially connected. The first surface and the third surface can be opposite to each other along the length direction, and the second surface and the fourth surface are opposite to each other. One end of the elastic part 1151 can be connected to the first surface, and the positioning part 1152 is provided at the other end of the elastic part 1151.

[0075] Among them, the extension length of the elastic part 1151 relative to the first surface along the second direction Y can be greater than or equal to 18 cm, so that the elastic part 1151 can better generate elastic deformation.

[0076] There is a sufficiently large gap between the elastic part 1151 and the second, third, and fourth surfaces to prevent interference between the elastic part 1151 and the second, third, or fourth surface, which may affect the elastic deformation of the elastic part 1151. For example, the distance between the elastic part 1151 and the second surface is greater than or equal to 16 mm and less than or equal to 20 mm, the distance between the elastic part 1151 and the third surface is greater than or equal to 16 mm and less than or equal to 20 mm, and the distance between the elastic part 1151 and the fourth surface is greater than or equal to 16 mm and less than or equal to 20 mm.

[0077] In some embodiments, the end face of the positioning part 1152 facing away from the elastic part 1151 can be spherical, which helps the positioning part 1152 slide more smoothly relative to the first support 111, and helps the positioning part 1152 slide more smoothly to disengage from the positioning hole 1111 or slide into and be clamped in the positioning hole 1111.

[0078] Please refer to Figure 2 and Figure 6 , in some embodiments, the support leg 110 may further include a first anti - detachment member 117 and a second anti - detachment member 119.

[0079] Among them, the second anti - detachment member 119 can be connected to the second support 113, the first anti - detachment member 117 can be connected to the first support 111, the first anti - detachment member 117 can be located in the moving path of the second anti - detachment member 119. Through the cooperation of the first anti - detachment member 117 and the second anti - detachment member 119, the sliding stroke of the second support 113 in the first direction X is restricted, thereby preventing the second support 113 from disengaging from the first support 111 when sliding along the first direction X.

[0080] As an example, please refer to Figure 2 , Figure 4 and Figure 6 , the first anti - detachment member 117 can be connected to the inner peripheral surface 1115 of the first support 111 and is located on one side of the first support 111 close to the first end face 1117. The second anti - detachment member 119 can be connected to the outer peripheral surface 1131 of the second support 113 and is located on one side of the second support 113 close to the fourth end face 1133. When the second support 113 slides along the first direction X until the second anti - detachment member 119 abuts against the first anti - detachment member 117, the first anti - detachment member 117 blocks the second anti - detachment member 119, thereby helping to prevent the second support 113 from disengaging from the first support 111 along the first direction X. For the convenience of assembly, the first support 111 and the second support 113 can adopt a detachable connection method, that is, when the second support 113 slides along the second direction Y, the second support 113 can slide to disengage from the first support 111.

[0081] In addition, the first anti-disengagement member 117 and the second anti-disengagement member 119 can also improve the wobbling condition of the first support member 111 and the second support member 113. Specifically, the first anti-disengagement member 117 can abut against the outer peripheral surface 1131 of the second support member 113, and the second anti-disengagement member 119 can abut against the inner peripheral surface 1115 of the first support member 111, thereby improving the wobbling condition of the first support member 111 and the second support member 113.

[0082] It can be understood that the shape of the first anti-disengagement member 117 can be designed according to requirements. For example, the first anti-disengagement member 117 can adopt an annular structure and be wound around the inner peripheral surface 1115 of the first support member 111, or the first anti-disengagement member 117 can adopt a semi-annular structure and be wound around a part of the inner peripheral surface 1115 of the first support member 111, or the first anti-disengagement member 117 can also adopt other shaped structures.

[0083] Similarly, the shape of the second anti-disengagement member 119 can also be designed according to requirements. For example, the second anti-disengagement member 119 can adopt an annular structure and be wound around the outer peripheral surface 1131 of the second support member 113, or the second anti-disengagement member 119 can adopt a semi-annular shape and be wound around a part of the outer peripheral surface 1131 of the second support member 113, or the second anti-disengagement member 119 can also adopt other shaped structures.

[0084] Please refer to Figure 2 、 Figure 4 and Figure 6 , in some embodiments, the first anti-disengagement member 117 can be located between the first end face 1117 and the second end face 1118, and at least two positioning holes 1111 can be distributed between the second end face 1118 and the first anti-disengagement member 117, that is, the first end face 1117, the first anti-disengagement member 117, the positioning holes 1111, and the second end face 1118 are distributed in sequence along the length direction.

[0085] The elastic positioning member 115 can be located between the third end face 1132 and the fourth end face 1133, and the second anti-disengagement member 119 can be located between the elastic positioning member 115 and the fourth end face 1133, that is, the third end face 1132, the elastic positioning member 115, the second anti-disengagement member 119, and the fourth end face 1133 are distributed in sequence along the length direction.

[0086] When the elastic positioning member 115 is clamped in the positioning hole 1111, the fourth end face 1133 is located between the first end face 1117 and the second end face 1118, and the third end face 1132 is located on the side of the first end face 1117 away from the second end face 1118. Thus, when the elastic positioning member 115 is clamped in the positioning hole 1111, one end of the second support member 113 provided with the third end face 1132 can be exposed outside the first support member 111, so as to facilitate the connection and fixation of the second support member 113 and the support plate 130; one end of the second support member 113 provided with the fourth end face 1133 can be located in the sliding channel 1116, which helps the first support member 111 to be stably placed on the ground.

[0087] In some embodiments, the distance between the first anti - detachment member 117 and the first end face 1117 can be less than the distance between the first anti - detachment member 117 and the second end face 1118, and the distance between the elastic positioning member 115 and the fourth end face 1133 is less than the distance between the elastic positioning member 115 and the third end face 1132, so as to extend the sliding stroke of the second support member 113, which helps to extend the length of the support leg 110 after elongation.

[0088] It can be understood that the smaller the distance between the first anti - detachment member 117 and the first end face 1117, and / or the smaller the distance between the elastic positioning member 115 and the fourth end face 1133, the longer the sliding stroke of the second support member 113.

[0089] In some embodiments, the first anti - detachment member 117 is provided with a guiding groove 1171 extending along the length direction and communicating with the sliding channel 1116; the support leg 110 further includes a guiding strip 120 that can slide in the guiding groove 1171; the guiding strip 120 is connected to the second support member 113 and extends along the length direction, which helps the second support member 113 to slide more smoothly. In addition, the cooperation between the guiding strip 120 and the guiding groove 1171 also helps to prevent the relative rotation between the first support member 111 and the second support member 113, and helps the positioning hole 1111 to be always located on the movement path of the elastic positioning member 115.

[0090] As an example, the guiding groove 1171 can be provided in the first anti - detachment member 117 and communicate with the sliding channel 1116. The guiding strip 120 can be arranged on the outer peripheral surface 1131 of the second support member 113 and extend along the length direction. The two ends of the guiding strip 120 along the length direction can respectively extend to the third end face 1132 and the fourth end face 1133. When the first support member 111 and the second support member 113 are assembled, the second support member 113 can be inserted into the sliding channel 1116 from one side of the second end face 1118 of the first support member 111, and the guiding strip 120 is aligned with the guiding groove 1171 to ensure that the positioning hole 111 is located on the movement path of the elastic positioning member 115.

[0091] In some embodiments, the second support member 113 and the guide bar 120 can adopt an integrally formed structure, which can further reduce the number of structural members of the support leg 110, reduce the assembly time and cost of the guide bar 120, simplify the structure of the support leg 110, and also help to enhance the connection strength between the second support member 113 and the guide bar 120, reducing the situation where the guide bar 120 detaches from the second support member 113.

[0092] In some embodiments, there can be one or more guide grooves 1171, and the number of guide bars 120 can be equal to the number of guide grooves 1171, which helps the second support member 113 to slide more smoothly. Here, "multiple" can refer to two or more.

[0093] When the number of guide grooves 1171 is multiple, the multiple guide grooves 1171 can be circumferentially distributed on the inner peripheral wall of the first anti - detachment member 117, and the multiple guide bars 120 can be circumferentially distributed along the outer peripheral surface 1131 of the second support member 113. The second anti - detachment member 119 can be disposed between two adjacent guide bars 120.

[0094] In some embodiments, the first anti - detachment member 117 and the first support member 111 can be an integrally formed structure, which can reduce the number of parts of the support leg 110, reduce the assembly process of the first anti - detachment member 117, and reduce the assembly time and cost of the support leg 110. In addition, due to the reduction in the number of structures of the support leg 110, it helps to better control the packaging standard of the support leg 110 or the height support device 100, and can also reduce the weight of the support leg 110 or the height support device 100, reducing the transportation cost.

[0095] Furthermore, since the first anti - detachment member 117 and the first support member 111 can be an integrally formed structure, the connection strength between the first anti - detachment member 117 and the first support member 111 is relatively high, which helps to improve the situation where the first anti - detachment member 117 detaches from the first support member 111, thereby reducing the situation where the second support member 113 detaches from the first support member 111 along the first direction X. And during packaging and transportation, it can avoid the situation of omission or loss of the first anti - detachment member 117.

[0096] As an example, the first anti - detachment member 117 and the first support member 111 can be plastic parts, and are integrally formed by injection molding.

[0097] In some embodiments, the second anti - detachment member 119 and the second support member 113 can be an integrally formed structure, thereby reducing the number of components of the support leg 110. There is no need to install the second anti - detachment member 119, reducing the assembly time and cost of the support leg 110. In addition, since the number of components of the support leg 110 is reduced, it helps to better control the packaging standard of the support leg 110 or the height support device 100, and can also reduce the weight of the support leg 110 or the height support device 100, reducing the transportation cost.

[0098] In addition, since the second anti - detachment member 119 and the second support member 113 can be an integrally formed structure, the connection strength between the second anti - detachment member 119 and the second support member 113 is relatively high, which helps to improve the situation where the second anti - detachment member 119 detaches from the second support member 113, thereby reducing the situation where the second support member 113 detaches from the first support member 111 along the first direction X. Also, during packaging and transportation, the situation where the second anti - detachment member 119 is omitted or lost can be avoided.

[0099] As an example, the second anti - detachment member 119 and the second support member 113 can be plastic parts, and are integrally formed by injection molding.

[0100] Please refer to Figures 2 to 3 , in some embodiments, the support plate 130 can include a first fixing portion 131. An end of the second support member 113 can be provided with a second fixing portion 1135 for cooperating with the first fixing portion 131. One of the first fixing portion 131 and the second fixing portion 1135 is a screw, and the other is a screw hole. The screw can be inserted into the screw hole to fix the support leg 110 to the support plate 130. Thus, there is no need for other fixing structures between the support leg 110 and the support plate 130, which helps to further reduce the number of components of the height support device 100.

[0101] As an example, the second fixing portion 1135 can be located on the third end face 1132 of the second support member 113. The second fixing portion 1135 can be a screw hole, and the screw hole can be provided on the third end face 1132. A screw inserted into the screw hole can be provided at the bottom of the support plate 130 so that the support plate 130 and the support leg 110 can be fixed.

[0102] As another example, the second fixing portion 1135 can be located on the third end face 1132 of the second support member 113. The second fixing portion 1135 can be a screw, and the screw can protrude from the third end face 1132. A screw hole inserted with the screw can be provided at the bottom of the support plate 130 so that the support plate 130 and the support leg 110 can be fixed.

[0103] Please refer to Figures 3 to 4, in some embodiments, the height support device 100 may further include an anti-slip pad 150. The anti-slip pad 150 may be connected to one end of the first support member 111 facing away from the support plate 130, which helps to reduce the situation of the support leg 110 sliding, so that the support leg 110 can more stably support the support plate 130.

[0104] As an example, the anti-slip pad 150 may include a clamped portion and an anti-slip portion connected to each other. The clamped portion may be clamped in the sliding channel 1116, and the anti-slip portion may be exposed outside the first support member 111 and abut against the second end face 1118. The support leg 110 may contact the ground through the anti-slip portion to play an anti-slip role.

[0105] Among them, the anti-slip pad 150 may be a plastic anti-slip pad, a rubber anti-slip pad or an anti-slip pad made of other materials.

[0106] In the support leg 110 and the height support device 100 provided in the embodiments of the present application, the second support member 113 is slidably connected to the first support member 111 along the length direction of the support leg 110. The first support member 111 is provided with at least two positioning holes 1111 along the length direction. The elastic positioning member 115 can be selectively clamped in one of the at least two positioning holes 1111 for adjusting the fixed position of the second support member 113 relative to the first support member 111, and the elastic positioning member 115 can also be elastically deformed to disengage from the positioning hole 1111, so that the position of the second support member 113 relative to the first support member 111 can be flexibly adjusted, and the length of the support leg 110 can be flexibly adjusted. The elastic positioning member 115 and the second support member 113 are integrally formed structures, which can reduce the number of structures of the support leg 110, reduce the assembly process of the elastic positioning member 115, simplify the structure of the support leg 110. In addition, during packaging and transportation, the situation of omission or loss of the elastic positioning member 115 can be avoided.

However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art to which the present invention pertains. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
