Description

Technical Field

[0001] The utility model belongs to the technical field of brackets, and more specifically relates to a floor bracket with a shock-absorbing function. Background Art

[0002] A floor stand, also known as a floor-type stand, can be placed directly on the ground. Once placed on the ground, a floor stand for electronic devices, with its long support rod, can support the device directly from the ground, rather than requiring a table or other high object as a support base. This broadens the use cases for electronic devices and allows them to be used in environments where a table or other object is not available. However, due to the long and generally thin support rods included in floor stands, the stand itself can easily wobble when a user touches the electronic device, affecting the user experience.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The various specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0027] In the following description, the terms "first, second, ..." are used solely to distinguish different objects and do not imply any similarities or connections between the objects. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to directions during normal use. The directions "left" and "right" refer to the left-right directions shown in the corresponding schematic diagrams, which may or may not be the left-right directions during normal use.

[0028] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element. "A plurality" means greater than or equal to two.

[0029] The present invention provides a floor stand with a shock-absorbing function. The electronic device may be a mobile phone, a tablet computer, etc. The floor stand can be placed directly on the ground or on a table. It should be noted that the placement scenario and placement orientation of the present invention do not limit the structure of the floor stand with a shock-absorbing function.

[0030] like Figure 1 As shown, the floor stand includes a load-bearing assembly 1, a support assembly 2, and a floor base 3. The load-bearing assembly 1 is used to clamp and secure electronic equipment. The support assembly 2 has a certain length, and its width and thickness are relatively small compared to its length. The support assembly 2 can be roughly regarded as a straight line or curved segment along its length. The length direction of the support assembly 2 can be understood as the direction in which the support assembly 2 has its largest dimension, represented by the dotted line a. In normal use, the floor base 3 can be considered to be placed on a horizontal surface, and the length direction of the support assembly 2 is the vertical direction.

[0031] like Figure 1 As shown, the bearing assembly 1 is connected to the supporting assembly 2, and the bearing assembly 1 is located on one side of the length direction a of the supporting assembly 2. When the floor stand is in use, the supporting assembly 2 is approximately in a vertical state, and the bearing assembly 1 is located on one side of the top of the supporting assembly 2. Figure 1As shown, the support assembly 2 can support the carrier assembly 1 to a suitable height, making it convenient for the user to perform operations such as clicking, writing, voice conversation, and video conversation on the electronic device clamped by the carrier assembly 1. In some embodiments, the carrier assembly 1 and the support assembly 2 are rotatably connected, and the rotation axis can be along the length of the support assembly 2, thereby achieving adjustment of the angle of the carrier assembly 1.

[0032] like Figure 1 As shown, the floor base 3 is connected to the support assembly 2, for example, the two are detachably fixedly connected. The floor base 3 is located on the other side of the length direction a of the support assembly 2. When the bracket is in use, the floor base 3 is located on one side of the bottom end of the support assembly 2. Figure 1 As shown, the floor-standing base 3 presses the bottom of the support assembly 2 by its own gravity to prevent the support assembly 2 from tipping over.

[0033] like Figure 2 and Figure 3 As shown, the floor stand also includes a shock-absorbing assembly 4, which is disposed within the cavity 20 of the support assembly 2, forming a concealed arrangement. That is, the user cannot observe the presence of the shock-absorbing assembly from the outside during use, thereby reducing interference with the user's use of the floor stand. It is understood that the shock-absorbing assembly 4 can also be disposed outside the cavity 20 of the support assembly 2, forming an exposed arrangement, which can also achieve the purpose of absorbing vibrations.

[0034] like Figure 1 As shown, since the support assembly 2, the bearing assembly 1 and the floor base 3 are connected as a whole, the vibration absorbed by the shock-absorbing group includes the vibration of the support assembly 2, the bearing assembly 1 and the floor base 3; when the bearing assembly 1 clamps the electronic device, the vibration absorbed by the support assembly 2 also includes the vibration of the electronic device. The shock-absorbing assembly 4 absorbs vibration in three ways, including but not limited to the following: First, the shock-absorbing assembly 4 moves in the cavity 20, and the shock-absorbing assembly 4 overcomes the air resistance to do work, thereby consuming kinetic energy and absorbing vibration. Second, the shock-absorbing assembly 4 converts the kinetic energy of the support assembly 2, the bearing assembly 1 and the floor base 3 into elastic potential energy, and uses air resistance to gradually decay the elastic potential energy, thereby absorbing vibration. Third, the shock-absorbing assembly 4 moves in the cavity 20, and the shock-absorbing assembly 4 cuts the magnetic lines of force during movement to generate electrical energy, thereby consuming kinetic energy and absorbing vibration.

[0035] The embodiment of the utility model arranges a shock-absorbing assembly within the support assembly. When a user touches the electronic device and generates vibration, the vibration is transmitted to the support assembly through the load-bearing assembly. Since the shock-absorbing assembly is arranged within the support assembly, the vibration can be absorbed, thereby reducing or eliminating the vibration of the support assembly and even the entire floor stand, thereby improving the user experience. Moreover, since the shock-absorbing assembly is arranged within the support assembly, the appearance of the floor stand is not affected, and the shock-absorbing assembly is protected by the support assembly and is not easily damaged.

[0036] In some embodiments, as Figure 2 and Figure 3 As shown, the shock absorbing assembly 4 includes a first elastic member 41 and a counterweight member 42. The first elastic member 41 can be any one of a spring, a flexible spring sheet, a rubber pad, and an air cushion. One end of the first elastic member 41 is connected to the support assembly 2, so that the kinetic energy of the support assembly 2, the bearing assembly 1 connected to the support assembly 2, and the ground base 3 can be transmitted to the first elastic member 41. The counterweight member 42 is connected to the other end of the first elastic member 41, so that the counterweight member 42 can move with the first elastic member 41. Compared with the shock absorbing assembly 4 provided with only the first elastic member 41, the overall weight of the shock absorbing assembly 4 provided with the counterweight member 42 is greatly increased, so that the shock absorbing assembly 4 can absorb greater vibrations.

[0037] In this embodiment of the utility model, the kinetic energy of the support assembly, the load-bearing assembly connected to the support assembly, and the ground base is transferred to the counterweight through the first elastic member. When the counterweight moves, on the one hand, the counterweight itself overcomes air resistance and performs work, consuming kinetic energy. On the other hand, the counterweight compresses the first elastic member, causing it to generate elastic potential energy. Therefore, during the process of compression and recovery, the first elastic member overcomes air resistance and performs work, consuming kinetic energy. In this way, the first elastic member and the counterweight work together to absorb vibration.

[0038] In some embodiments, as Figure 2 and Figure 3 As shown, the shock absorbing assembly 4 also includes a second elastic member 43. The first elastic member 41, the counterweight member 42, and the second elastic member 43 are arranged in sequence along the length direction a of the support assembly 2. One end of the second elastic member 43 is connected to the end of the counterweight member away from the first elastic member 41, and the other end is connected to the support assembly 2. In other words, one end of the counterweight member 42 is connected to the first elastic member 41, and the other end of the counterweight member 42 is connected to the second elastic member 43. In this way, the kinetic energy of the support assembly 2, the bearing assembly 1 connected to the support assembly 2, and the ground base 3 is transmitted to the counterweight member 42, not only through the first elastic member 41, but also through the second elastic member 43. Compared with only setting the first elastic member, the kinetic energy absorption speed of the shock absorbing assembly is improved, thereby effectively improving the shock absorption effect between the landing.

[0039] In addition, the practical example of the present invention uses two elastic members. Since both elastic members generate elastic potential energy, more kinetic energy can be consumed through compression deformation and recovery deformation. Since the first elastic member, the counterweight member, and the second elastic member are arranged in sequence along the length direction a of the support assembly, if the counterweight member moves along the length direction a, one spring is in compression and the other spring may be in tension. Thus, when one of the springs drives the counterweight member to reset, the other spring drives the counterweight member to move. In the process of the two springs alternately deforming and resetting, the number of movements of the counterweight member per unit time can be increased by two times compared to when only one spring deforms and resets, thereby absorbing more vibration. In this way, the arrangement of the two elastic members improves the vibration absorption effect of the shock-absorbing assembly, and can quickly stop the vibration of the electronic device when the user is using the electronic device, further improving the user experience of the floor stand.

[0040] In some embodiments, as Figure 2 As shown, a gap exists between the outer wall of the counterweight 42 and the inner wall of the cavity 20 along a direction perpendicular to the longitudinal direction a, allowing the counterweight 42 to swing around the longitudinal direction a within the cavity 20. The counterweight 42 is connected to a first elastic member 41 and a second elastic member 43 along the longitudinal direction a. The counterweight 42 can generate movement along the longitudinal direction a by compressing or stretching the first elastic member 41 and the second elastic member 43. This allows the counterweight to move 360° in all directions within the cavity, meaning that the counterweight can absorb vibrations generated in all directions by the load-bearing assembly, the support assembly, and the floor-standing base.

[0041] In some embodiments, as Figure 3 As shown, the first elastic member 41 and the second elastic member 43 are both springs, which are suitable for being arranged as shown in FIG. Figure 2 The two springs remain compressed, and even a slight movement of the counterweight 42 generates a rebound force, causing the counterweight 42 to move more violently. Compared to when both springs are in their original state (i.e., undeformed) or in a stretched state, the counterweight of the present invention generates greater kinetic energy through the compressed springs, thereby better absorbing vibrations.

[0042] In some embodiments, as Figure 3As shown, the first elastic member 41 and the second elastic member 43 are both conical springs extending along the longitudinal direction a. The top end of the conical spring is connected to the counterweight 42, and the bottom end of the conical spring is connected to the support assembly 2. The top end of the conical spring can be understood as the end with a smaller cross-section perpendicular to the longitudinal direction a, while the bottom end of the conical spring can be understood as the end with a larger cross-section perpendicular to the longitudinal direction a. The conical spring arrangement provides greater clearance perpendicular to the longitudinal direction a for the counterweight, allowing it to generate greater oscillations and absorb greater vibrations.

[0043] In some embodiments, as Figure 4 As shown, the counterweight 42 is a columnar structure extending along the longitudinal direction a. The columnar structure has a first step surface 421 and a second step surface 422 formed at both ends of the longitudinal direction a. The first elastic member 41 and the second elastic member 43 are in contact with the first step surface 421 and the second step surface 422, respectively, so that the first elastic member 41 and the second elastic member 43 can maintain a compressed state. Specifically, the first step surface 421 and the second step surface 422 are both planes perpendicular to the longitudinal direction a. The formation of the first step surface and the second step surface makes the cross-section of the two ends of the counterweight perpendicular to the longitudinal direction a smaller than the cross-sectional area of ​​the middle part of the counterweight. Then, the first elastic member and the second elastic member are sleeved on the two ends of the counterweight, and can respectively contact the first step surface and the second step surface and maintain a compressed state.

[0044] In some embodiments, as Figure 1 As shown, the support assembly 2 includes a first support rod 21 and an adapter 22 .

[0045] like Figure 5 As shown, the first support rod 21 extends along the length direction a and defines a first sub-cavity 210 therein. The cavity 20 includes the first sub-cavity 210, and the support assembly 2 is disposed within the first sub-cavity 210. The first support rod 21 defines a first opening 2101 at a first end 211 in the length direction a, communicating with the first sub-cavity 210. The adapter 22 is partially inserted into the first sub-cavity 210 from the first end 211 to close the first opening 2101 of the first sub-cavity 210.

[0046] like Figure 2 and Figure 3 The adapter 22 is rotatably connected to the carrier assembly 1, and the adapter 22 is fixedly connected to the first support rod 21. The embodiment of the utility model, through the arrangement of the first support rod and the adapter, enables the carrier assembly to rotate relative to the first support rod, thereby facilitating adjustment of the orientation of the electronic device held by the carrier assembly and improving user convenience.

[0047] In some embodiments, as Figure 2As shown, the end of the adapter 22 located outside the first sub-cavity 210 forms a spherical body 221. A clip 10 is provided on the back of the carrier assembly 1. The clip 10 has a groove 101 therein. The spherical body 221 is inserted into the groove 101 and connected to the clip 10 and can rotate around the clip 10. Specifically, the inner wall of the groove 101 is formed with a serrated portion. The serrated portion can be deformed after being squeezed by the spherical body 221. Friction exists between the serrated portion and the spherical body 221, that is, there is a certain amount of damping between the adapter 22 and the clip 10. When the user stops rotating the carrier assembly, this damping effect can stabilize the carrier assembly in a certain position, improving the user's convenience.

[0048] In some embodiments, as Figure 1 As shown, the support assembly 2 further includes a rotating shaft 23 and a second support rod 24. Figure 5 As shown, the rotating shaft 23 is connected to the second end 212 of the length direction a of the first support rod 21; the second support rod 24 is connected to the end of the rotating shaft 23 away from the first support rod 21, and the end of the second support rod 24 away from the rotating shaft 23 is connected to the ground base 3 (as shown in FIG. Figure 1 wherein the rotating shaft 23 can rotate about an axis perpendicular to the length direction a, so that the first support rod 21 can rotate relative to the second support rod 24. In this way, the overall height of the floor base and the orientation of the first support rod can be adjusted, thereby adjusting the height and orientation of the supporting assembly.

[0049] like Figure 6 As shown, the rotating shaft 23 includes a first rotating shaft 231, a second rotating shaft 232, and a pin 233. The second rotating shaft 232 is disposed on either side of the first rotating shaft 231. Specifically, the first rotating shaft 231 is formed into a disc-shaped structure, and the second rotating shaft 232 is formed into two spaced-apart disc-shaped structures. The disc-shaped structure of the first rotating shaft 231 is sandwiched between the two disc-shaped structures of the second rotating shaft 232, allowing the first rotating shaft 231 to rotate within the second rotating shaft 232. These disc-shaped structures are provided with connecting holes for the pin 233 to pass through. The pin 233 passes through these connecting holes, allowing the first rotating shaft 231 and the second rotating shaft 232 to rotate relative to each other. Furthermore, the end of the first rotating shaft 231 away from the second rotating shaft 232 is fixedly connected to the first support rod 21, and the end of the second rotating shaft 232 away from the first rotating shaft 231 is fixedly connected to the second support rod 24, allowing the first support rod 21 and the second support rod 24 to rotate relative to each other. The embodiment of the utility model can adjust the height and orientation of the bearing assembly through the provision of the rotating shaft and the second support rod, which is beneficial for the user to adjust to different heights and orientations and improves the user's usage experience.

[0050] like Figure 6As shown, the end of the first rotating shaft 231 connected to the first support rod 21 has a hollow interior and is provided with a plurality of first through-holes 2311 at the end of the first rotating shaft 231 connected to the first support rod 21. The first through-holes 2311 extend along the length direction a and are spaced circumferentially. The provision of the first through-holes reduces the strength of the first rotating shaft near the first through-holes, making it susceptible to deformation. This allows the first rotating shaft and the first support rod to be easily interlocked when connected.

[0051] In some embodiments, as Figure 5 As shown, the second support rod 24 has a second sub-cavity 240, the cavity 20 includes the second sub-cavity 240, and the shock absorbing component 4 (such as Figure 4 The specific structure and connection method of the shock absorbing assembly 4 in the second sub-cavity 240 are the same as those in the first sub-cavity 210, and will not be repeated here. In this embodiment of the utility model, the shock absorbing assembly has two groups, and the two groups of shock absorbing can improve the shock absorption effect of the floor stand.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
