Description

Technical Field

[0001] This application relates to the technical field of photographic auxiliary equipment, and particularly relates to a tripod and its pan-tilt head. Background Art

[0002] A tripod is a stable support widely used to support cameras, telescopes, video cameras, or other devices. A typical tripod consists of three legs and a base, with a support point at the end of each leg, thus providing a stable platform for the device during operations such as shooting or recording to prevent the camera or other device from producing blurred or shaky images due to handholding or an unstable surface.

[0003] To improve portability, the legs of a tripod are usually designed to have a certain degree of freedom of movement and can be retracted into a specific storage compartment through a series of deformation and movement operations. However, during daily use, the legs of a tripod often adhere to dust, sand, or similar small adherents (especially when used on the beach). At this time, it usually requires the user to manually clean them. Moreover, once not cleaned completely, the adherents are easily brought into the relatively enclosed storage compartment, further increasing the difficulty of cleaning and handling.

[0061] The present application will be described in detail below with reference to specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present application and its applications.

[0062] It should be noted that, unless otherwise clearly specified or limited, the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. used in this specification are based on the orientation or positional relationships shown in the drawings. These terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. The terms "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features; the meaning of "a plurality" is two or more; "and / or" includes any and all combinations of one or more of the related listed items. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0063] A "tripod" refers to a structural support assembly that provides support, stability, and positioning for a specific supported object (e.g., a camera or a smartphone). It can ensure that the supported object is in the correct position, bear and absorb the stress and deformation caused by the supported object, thereby providing a stable shooting environment for the supported object and improving the shooting quality.

[0064] To meet the requirements of improving portability, expanding applicable scenarios, etc., tripods can usually be designed with structural components having variable forms. There can be an appropriate degree of freedom of movement between the composed structural members so that they can change or switch between different states to meet different usage needs. For example, a tripod can switch between a carrying state and an unfolded state to respectively meet the usage needs of being easy to carry and stably supporting.

[0065] Figure 1 This is a schematic structural diagram of the tripod provided by the embodiment of the present application. As Figure 1 shown, the tripod includes: a base 10, a scraping member 20, and legs 30.

[0066] Among them, the base 10 is the main structural part of the tripod. It has a certain space inside, and based on this, an internal space located inside the base 10 and an external space located outside the base 10 can be defined or delimited in a complete three-dimensional space.

[0067] As Figure 3As shown, a leg mounting hole 11 is provided in the base 10. The leg mounting hole 11 is a notch that penetrates the structural entity of the base. It connects the internal space and the external space of the base and can be used to mount the leg 30.

[0068] Specifically, please continue to refer to Figure 3 , the base 10 can generally be composed of a bottom 12 and a side wall 13. The bottom 12 refers to the bottom surface part of the entire base 10, and the side wall 13 refers to the wall surface extending from the outer peripheral edge of the bottom 12 to a certain height. Correspondingly, the leg mounting hole 11 can be provided in the bottom 12 of the base and is adapted to the cross-sectional shape of the leg, so as to play a guiding role and guide the leg 30 to move relative to the base in the height direction.

[0069] Furthermore, please continue to refer to Figure 3 , the leg mounting hole 11 can also extend to the side wall 13 and occupy a part of the side wall 13, so that the leg 30 also has a degree of freedom of movement to rotate relative to the base 10.

[0070] In addition, a limiting structure 14 formed by a part of the structural entity of the side wall 13 can be reserved at the top of the leg mounting hole 11. The limiting structure 14 can abut against the leg 30, thereby limiting the maximum rotation angle of the leg 20.

[0071] In some embodiments, the degree of freedom of movement for the leg to rotate relative to the base can be realized by a rotating assembly 60 provided between the leg 30 and the base 10.

[0072] Among them, the rotating assembly 60 can be composed of a rotating shaft 61 and a supporting structure 62. The rotating shaft 61 protrudes from both side surfaces of the leg 30 and is located at a position close to the first end and far from the second end. The supporting structure 62 is arranged in the internal space of the base 10 and has an arc-shaped depression.

[0073] Thus, when the leg 30 moves to the target position, the rotating shaft 61 can move into the corresponding arc-shaped depression of the supporting structure 62, enabling the leg 30 to rotate relative to the base 10 around the rotating shaft 61.

[0074] The scraping member 20 is a member made of a material with a certain elasticity. It covers at least a part of the edge of the leg mounting hole 11. In this application, it can be understood that the "edge of the leg mounting hole" actually refers to the edge of the structural entity of the base that encloses the notch. Correspondingly, the term "covers" is used to represent the situation where the scraping member 20 wraps or covers the structural entity of the base.

[0075] Specifically, the scraping member 20 can be obtained by any suitable type of material or process. For example, it can be made of materials such as silica gel, thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), dust-proof cotton, etc., and the base with the scraping member covering the foot mounting holes can be obtained by double-shot injection molding. Such a manufacturing method can achieve high processing accuracy to ensure sufficient contact between the scraping member and the foot, and improve the scraping effect on the adhesion. Alternatively, the base with the scraping member covering the foot mounting holes can also be obtained by an adhesive process, and the scraping member 20 is adhered to the foot mounting holes of the base 10 in a suitable manner.

[0076] The foot 30 is a component used to transfer the load borne to the ground or the support surface. It is assembled in the foot mounting hole 11, and the scraping member 20 is clamped between the base 10 and the foot 30.

[0077] In this application, the term "assembly" is used to represent a connection method of combining two components or assemblies according to specific requirements to form a complete mating structure and achieve the required target function. It only indicates that there is an associated relationship between the components, and does not limit the specific connection method and the specific setting form of the components.

[0078] In some embodiments, the feet 30 can be provided in a suitable number to provide stable and reliable support. For example, the three feet shown in the accompanying drawings of the specification of this application. Alternatively, a larger number can also be provided, for example, four or five feet.

[0079] Specifically, the feet 30 can be set to a suitable shape according to the actual needs. For example, the overall flat cuboid shape shown in the accompanying drawings of the specification.

[0080] For the sake of convenience of description, in this application, the two ends of the feet away from each other are respectively called the "first end" and the "second end". Preferably, the feet 30 can be provided with a recess extending from the first end to the second end.

[0081] The "recess" refers to the part where the surface is recessed inward, and its specific recess degree or size can be set according to the actual needs. For example, as Figure 5 shown, on the basis that the feet 30 are in an overall flat cuboid shape, a recessed part recessed inward can be provided on one of the surfaces, so that the cross-section of the entire feet 30 is in a structure similar to a C shape. Such a structural design can effectively reduce the weight of the feet, save materials and reduce the manufacturing cost.

[0082] In this embodiment, the support leg 30 is configured as a movable component. Figure 2 As shown, it can move in the height direction relative to the base 10, so as to switch the tripod between different states. When the support leg 30 moves relative to the base 10, at least a portion of the scraping member 20 covered in the support leg mounting hole 11 will keep in contact with the support leg 30.

[0083] By maintaining contact in this way, the support leg can be automatically cleaned, and the adherents on its surface can be automatically scraped off during the movement of the support leg. Preferably, the surface roughness of the support leg surface can be controlled to be lower than a preset roughness threshold (the roughness threshold is an empirical value and can be set according to actual needs). In other words, the outer surface of the support leg is kept smooth or the texture on its surface is reduced, thereby improving the scraping effect.

[0084] In some embodiments, the entire edge of the support leg mounting hole 11 may be covered by the scraping component 20 , and an interference fit is formed between the support leg 30 and the support leg mounting hole 11 covered with the scraping component.

[0085] Here, "interference fit" refers to a mechanical connection method that makes the sizes of two parts slightly different so that they form a certain pressure or friction when assembled. Therefore, the interference fit connection method can form a certain pressure or friction between the support leg 30 and the scraping component 20, ensuring that the scraping component 20 and the support leg 30 can maintain close contact throughout the movement of the support leg.

[0086] In addition, the friction force formed between the support leg 30 and the scraping member 20 also has the effect of preventing and limiting its movement. Thus, the support leg 30 can be prevented from being loose or shaking during movement, which can effectively improve the user experience.

[0087] Specifically, the scraping component can be made of a specific material and have a coating layer with a preset thickness. The preset thickness is a value that can be set by a technician according to actual conditions.

[0088] Preferably, the thickness can be set appropriately so that the interference between the two is within a preset value range, thereby providing a more appropriate friction or pressure. For example, the interference can be appropriately set so that the resistance or friction applied to the support leg 30 can be substantially greater than the weight of the support leg itself. Such a design can achieve the effect of hovering at any position during the movement of the support leg entering and leaving the receiving space without automatically falling, which can effectively improve the user experience.

[0089] In other embodiments, Figure 4As shown, the scraping member 20 may also be provided with a plurality of protruding portions 21 protruding from the working surface. The working surface refers to the surface facing or approaching the leg, and is called the working surface because it can contact the leg during movement and play a scraping role.

[0090] These protruding portions 21 protruding from the working surface can be selected to adopt any suitable type of protrusion according to actual needs, as long as it can reduce the contact area between the working surface and the leg 30.

[0091] For example, please continue to refer to Figure 4 , the protruding portion 21 may be a rib extending on the working surface. It surrounds the outer peripheral edge of the entire leg and is perpendicular to the moving direction of the leg. Preferably, a plurality of these ribs may also be provided, and two adjacent ribs are arranged in parallel at a preset distance to provide a better cleaning effect.

[0092] At least one advantageous aspect of the protruding portion provided in the embodiment of the present application is that by providing additional protruding portions (for example, ribs), the surface contact between the scraping member and the leg can be changed to line contact or point contact, thereby reducing the friction force generated between the two and at the same time not having an adverse effect on the scraping and cleaning effect, and the cleaning range can also cover the entire surface of the leg.

[0093] In addition to controlling the contact area of the scraping member 20 to improve and reduce the friction force, the hardness of the scraping member 20 can also be controlled to help improve the actual application performance of the tripod. For example, the target hardness of the scraping member 20 can be controlled within the range of 20-100 degrees (Shore hardness) to ensure a scraping effect that meets the use requirements.

[0094] Under the same interference amount, a higher hardness can achieve a better scraping effect, but it will cause an increase in the friction force between the leg and the scraping member. A softer scraping member can reduce the friction force and facilitate the user's operation of the leg, but it will reduce the scraping effect.

[0095] During the implementation of the present application by the applicant, it was surprisingly found that by controlling the target hardness within the range of 60-70 degrees (Shore hardness), a balance between the friction force and the scraping effect can be achieved, that is, a better scraping effect can be obtained, and the friction force will not be too high to affect the use experience.

[0096] Figure 6 It is a schematic diagram of the pan-tilt when the tripod provided in the embodiment of the present application is in the deployed state. Figure 7 It is a schematic diagram of the pan-tilt when the tripod provided in the embodiment of the present application is in the carrying state. The following is combined with Figure 6 and Figure 7, describe in detail the switching process between the carrying state and the deployed state of the tripod.

[0097] As Figure 6 shown, when in the deployed state, the multiple legs 30 of the tripod are spaced apart from each other and extend outward from different directions of the base. The leg rotated to the target angle relative to the base abuts against the limiting mechanism to form a stable support structure.

[0098] After use, the multiple legs of the tripod can be rotated in a direction approaching each other and retracted to a position substantially parallel to the height direction of the base (this can also be referred to as the retracted state at this time). Subsequently, the legs can be pushed into the receiving cavity along the height direction of the side wall of the base to switch to the carrying state (as Figure 7 shown).

[0099] During the process of pushing the legs into the receiving cavity, the scraping member surrounding the outer periphery of the legs will maintain close contact with the legs, thereby scraping off the adhesives on the surface of the legs, achieving the cleaning of the leg surface, and preventing the adhesives from entering the receiving cavity.

[0100] Moreover, the interference fit between the leg mounting hole coated with the scraping member and the leg can form a certain pressure on the leg, preventing the leg from automatically sliding due to its own gravity, and can achieve the effect of hovering at any position, with a good user experience.

[0101] It should be noted that Figure 6 and Figure 7 exemplarily show the case where the tripod 1 is provided with three legs, but those skilled in the art can understand that the tripod 1 can also be provided with more or fewer legs according to the actual needs, or adopt different leg arrangement forms, and are not limited to Figure 6 and Figure 7 shown.

[0102] In some embodiments, for the movement process of the legs 30 relative to the base 10 during the state switching process of the tripod, other structural components can also be provided to help improve the user experience of the tripod.

[0103] For example, as Figure 9 shown, the tripod can further include: an abutting member 50.

[0104] Among them, the abutting member 50 is a structure with at least a part being elastic. It is fixedly arranged in the receiving space, abuts against at least a part of the leg 30 and forms a first elastic force F1.

[0105] In the present application, the "first elastic force" is the acting force that restricts the movement of the support feet 30 relative to the base 10. The magnitude of this first elastic force is determined by the elasticity and the degree of extrusion deformation of the abutting member 50, and it can be reasonably set according to the needs of the actual situation, as long as it can keep the position of the support feet 30 fixed without external acting forces.

[0106] Specifically, the abutting member 50 can be arranged in a paired manner with the support feet 30. In other words, one abutting member 50 cooperates with one support foot 30 to ensure the positioning effect on all the support feet 30.

[0107] In this text, for the convenience of description, the two surfaces of the support feet 30 facing away from each other are respectively called the "first surface" and the "second surface". Please continue to refer to Figure 3 , the first surface of the support feet 30 is the surface close to the inner wall of the housing 2, while the second surface is the surface abutting against the abutting portion 50. In other words, the first surface of the support feet 30 can face the housing 2, and its back is abutted by the abutting member 50, and the abutting member 50 forms the first elastic force to make the support feet 30 closely adhere to the inner wall of the housing 2.

[0108] Thus, the first elastic force F1 can make the support feet 30 located in the receiving space closely adhere to the inner wall of the housing 2, without shaking or swinging, avoiding problems such as abnormal noises during carrying and moving. Moreover, this first elastic force can also prevent the support feet 50 from slipping by itself during the movement along the set direction, thereby achieving the effect of the support feet hovering at any position.

[0109] In some other embodiments, as Figure 10 shown, the additionally provided abutting member 50 can also abut against the first end of the support feet when the support feet rotate to the target angle, providing a resistance with a suitable magnitude to restrict the rotation of the support feet 30, so that the support feet 30 can maintain their original angles unchanged. In the present application, for the convenience of description, the resistance formed by the abutting member 50 that restricts the rotation of the support feet 30 relative to the base is called the "second elastic force F2".

[0110] Preferably, as Figure 11 shown, the above-mentioned abutting member 50 can also be provided with a protrusion 51. Correspondingly, the first end of the support feet 30 is also provided with a corresponding abutting surface 31. When the support feet rotate to the target angle, the protrusion 51 can be in contact with the abutting surface 31, thereby forming the required second elastic force. In the present application, the term "correspondingly" is used to indicate that the protrusion 51 and the abutting surface 31 have complementary shapes. Thus, the abutting member 50 can be in full contact with the first end of the support feet 30, providing a stable and reliable second elastic force.

[0111] For example, as Figure 11As shown, the protrusion 51 can be an arc-shaped protrusion with a circular cross-section, and the abutting surface 31 is correspondingly set to one or more circular concave surfaces with a curvature and size adapted thereto. Alternatively, as Figure 12 shown, the abutting surface 31 can also be set as an inclined surface with a specific angle, and sufficient contact with the protrusion 51 can also be maintained.

[0112] An advantageous aspect of the specific contact structure design between the abutting component and the foot provided in the embodiments of the present application is that it can avoid the generation of play between the two components and ensure the firmness and reliability of the contact between the components.

[0113] In some embodiments, as Figure 13 shown, the abutting component 50 can be simply implemented by an elastic arm 50a. The elastic arm 50a includes: a base 51a and an arm portion 52a.

[0114] Among them, the base 51a can be fixed to the bottom of the base. The arm portion 52a extends from the end of the base in a direction approaching the side wall. The arm portion 52a has a target length so that the arm portion 52a can abut against the second surface or the first end of the foot to respectively form the aforementioned first elastic force or second elastic force.

[0115] Specifically, when the foot 30 moves in the height direction, the end of the arm portion 52a abuts against the second surface of the foot 30 and the elastic arm 50a undergoes elastic deformation.

[0116] At this time, the tendency of the elastic arm 50a to restore its initial shape will cause the foot 30 to be not easily slipped out of the accommodation cavity due to its own gravity through the arm portion 52a abutting against the second surface of the foot 30, and additional force needs to be applied by the user.

[0117] Preferably, the arm portion 52a can be inclined, with a certain inclination angle with respect to the height direction, and a certain preload is set. Such a setting method can ensure that the foot 30 can maintain sufficient contact with the end of the arm portion 52a during the entire movement in the set direction, thereby reducing the requirement for processing accuracy and improving the reliability of use.

[0118] After the foot rotates to the target angle, the first end of the foot 30 abuts against the main body portion of the arm portion 52a. At this time, if the foot 30 wants to rotate in the reverse direction and switch from the deployed state to the carrying state, it needs to squeeze the arm portion 52a to deform and disengage from the abutting component 50 to achieve.

[0119] Thus, by setting an appropriate elastic coefficient for the elastic arm, the reverse rotation of the foot 30 can be blocked through the arm portion 52a, ensuring that the foot 30 will not automatically reset to the retracted state due to gravity.

[0120] In some other embodiments, as Figure 14 shown, the elastic arm 50a can be fixed to the base in a detachable manner to obtain advantages in terms of processing, material selection, and maintenance. For example, the base 51a can be provided with positioning holes of appropriate sizes and fixed to the base by fixing screws 53a or similar fixing means. Alternatively, the elastic arm 50a can also be a component integrally formed with the base 12 to obtain the advantages of a compact space and enhanced structural strength.

[0121] In some other embodiments, as Figure 15 shown, the abutting member 50 can also be composed of a spring 51b and a fixing post 52b.

[0122] Among them, the spring 51b can be connected in abutment between the base and the fixing post 52b and act as a compression spring so that the fixing post 52b has a tendency to move in a direction approaching the side wall.

[0123] Specifically, the fixing post 52b has an appropriate length, and its end can abut against the second surface of the support leg, thereby playing a role similar to that of an arm and forming the above-mentioned first elastic force.

[0124] When the support leg 30 rotates to the target angle, the fixing post 52b further extends under the action of the spring, forming an inclined contact surface that abuts against the first end of the support leg, thereby generating the above-mentioned second elastic force and preventing the support leg 30 from automatically resetting to the retracted state due to the action of gravity.

[0125] It should be noted that based on the inventive concept provided in the embodiments of the present application, other similar elastic mechanisms can also be used to replace the above-mentioned compression spring, as long as the required first elastic force and second elastic force can be generated.

[0126] The support force of the traditional tripod design has certain limitations on the structural design. The following takes Figure 16 as an example for illustration. As Figure 16 shown, when the tripod is in the deployed state, the entire support leg 30 can be regarded as a simplified lever. The part of the support leg end in contact with the ground is marked as point A, the position where the support leg abuts against the side wall of the base is marked as point B, which is also the fulcrum of the lever. And the position where the rotation axis of the support leg is located is point C.

[0127] According to the principle of force analysis of the lever, it can be known that in the equilibrium state, the magnitudes of the acting forces at points A and C should satisfy the following formula (1):

[0128] Fa*AB = Fc*BC (1)

[0129] Among them, Fa is the force exerted on the outrigger 30 at point A. Fc is the force borne by the rotating shaft of the outrigger.

[0130] It can be understood that due to the limitation of the base size, the length of BC (i.e., the distance between the rotating shaft and the side wall) is significantly less than the length of AB. As a result, the force Fc borne by the rotating shaft is several times that of Fa, which requires a very high structural strength for the rotating shaft itself, and problems such as shaft breakage are likely to occur during use.

[0131] Therefore, the embodiment of the present application also provides an improved tripod. Through a specific support structure design, this tripod can change the force application point of the outrigger inside the base and extend the force arm, thereby helping to reduce the force borne by the rotating shaft when the outrigger is in use, so as to reduce the strength requirement for the rotating shaft. As Figure 17 shown, this tripod further includes an additional support structure 70.

[0132] Among them, the support structure 70 is located in the internal space of the base and is used to support and hold the relevant components of the outrigger 30. When the outrigger 30 rotates to the target angle where it abuts against the limiting structure 14, it can provide support and hold for the part of the outrigger 30 located in the internal space, thereby providing an additional support force for it.

[0133] Specifically,

[0134] Taking the outrigger 30 as a reference, the distance between the position where the rotating assembly 60 is located and the second end of the outrigger is greater than the distance between it and the first end of the outrigger. In other words, the rotating shaft formed by the rotating assembly 60 is located near the first end and far from the second end. Moreover, the rotating assembly 60 is located between the support structure 70 and the side wall of the base, and the outrigger 30 can rotate around its center. In other words, the support structure 70 is farther from the side wall relative to the rotating assembly 60.

[0135] Therefore, while the first surface of the outrigger 30 abuts against the limiting structure 14, the second surface of the outrigger 30 can abut against the support structure 70, and the support structure 70 provides part or all of the support force.

[0136] Figure 18 For Figure 17 the force analysis schematic diagram of the tripod shown. As Figure 18 shown, the entire outrigger 30 can be regarded as a simplified lever. The part where the outrigger end contacts the ground is marked as point A, the position where the outrigger abuts against the side wall of the base is marked as point B, which is also the fulcrum of the lever. The position where the rotating shaft of the outrigger is located is point C, and the part where the support structure 70 contacts the outrigger is point D.

[0137] Relative to Figure 16In this case, due to the additional provision of a relatively rear support structure 70, the force application point within the internal space of the base is accordingly shifted rearward to point D. In the equilibrium state, the magnitudes of the forces applied at points A and D satisfy the following equation (2):

[0138] Fa*AB = Fd*BD (2)

[0139] Wherein, Fa is the force applied at point A by the support leg 30. Fd is the force borne by the force application point of the support leg.

[0140] On the one hand, since point D is a relatively rear force application point, on the basis that Fa*AB remains unchanged, the magnitude of the force borne by the entire support leg can be effectively reduced. On the other hand, the position C where the rotating shaft is located no longer serves as an independent force application point, and a certain amount of support and bearing can be provided by the support structure.

[0141] Thus, the force borne by the rotating assembly 60 can be greatly reduced, and the required structural strength requirements can also be correspondingly reduced. It can be achieved at a lower cost (for example, the rotating shaft is processed into a smaller or shorter size, saving the occupied space), and has good application prospects (for example, based on the reduction of the force at the force application point of the support leg, the support leg can be made of plastic material to greatly improve production efficiency and reduce costs. Alternatively, the support leg can also be made of metal material).

[0142] In some embodiments, as Figure 19 shown, the supporting structure 62 can have a specific structural design such that when the support leg 30 rotates to the target angle, there is a gap between the rotating shaft 61 and the supporting structure 62. The size of this gap can be determined by those skilled in the art according to actual needs. In other words, the rotating shaft 61 adopts a clearance design, and there is an appropriate clearance amount between it and the supporting structure 62.

[0143] At least one advantageous aspect of the above-mentioned rotating shaft clearance design is that it can further reduce the force borne by the rotating shaft, making the force borne by the support leg within the internal space of the base mainly borne by the support structure 70, providing greater flexibility for the application of the rotating shaft.

[0144] Specifically, please continue to refer to Figure 19 , the above-mentioned rotating shaft 61 can be provided with two. The two rotating shafts 61 are respectively detachably fixed on both sides of the support leg 30 and are arranged along the same axis. Figure 19 exemplarily shows that the detachable fixed connection between the rotating shaft 61 and the support leg 30 is achieved by means of a threaded connection. However, those skilled in the art can understand that other any suitable detachable connection means can also be adopted.

[0145] At least one advantageous aspect of the above-described detachable fixed connection method is that it can provide great convenience for the installation, processing, and maintenance of the rotating shaft. Especially when using a metal method, compared with an integrally formed design, the processing difficulty and cost of the detachable structural design can be significantly reduced.

[0146] In some embodiments, as Figure 20 shown, the support structure 70 may include: a support structure body 71 and a support surface 72.

[0147] Among them, the support structure body 71, as the basic structural part, is fixed to the bottom of the base and has a specific height. Alternatively, the support structure body 71 can also be a part of the base, extending from the bottom to the aforementioned specific height. The specific value of this specific height can be determined by those skilled in the art according to the actual needs, as long as it ensures contact with the support feet 30, which will not be elaborated here.

[0148] The support surface 72 is the surface in contact with the support feet 30. It can be formed at the top of the support structure body 71 and can be a contact surface of any suitable shape. For example, the support surface 72 can be an inclined surface having an inclination angle adapted to the support feet rotated to the target angle, so as to have sufficient contact area with the support feet to reduce the pressure and avoid damage to the support feet.

[0149] In some embodiments, the support feet 30 rotated to the target angle can also be designed to have the freedom to move in the direction approaching the base. As Figure 21 shown, a locking structure 80 is correspondingly provided inside the base 10.

[0150] Among them, the locking structure 80 is a related component used to exert resistance or limitation on the rotation of the support feet 30. Its position inside the base is further back relative to the support structure, that is, the distance between the locking structure 80 and the side wall of the base is greater than the distance between the support structure 70 and the side wall. Thus, the force application point of the support feet can be further moved backward, so that the acting force applied at the force application point can be further reduced.

[0151] Specifically, as Figure 22 shown, after the support feet 30 are engaged with the locking structure 80, in addition to being able to contact the second surface of the support feet 30 and play the same supporting and bearing role as the support structure, the locking structure 80 can also contact the first surface of the support feet 30 located in the internal space of the base to limit the rotation of the support feet 30 and prevent the support feet 30 from rotating reversely from the target angle to the angle at the recovery state due to their own gravity.

[0152] In the actual use process, after rotating to the target angle, the supporting leg 30 can also move in the direction approaching the base. As the supporting leg 30 moves, its first end is correspondingly engaged with the locking structure 80, so that the locking structure can play its role of restricting the rotation of the supporting leg and supporting and bearing it. In this article, the term "engagement" is used to represent the situation where there is a physical structural connection or contact between two components.

[0153] Specifically, as Figure 21 shown, the locking structure 80 can be formed by a locking structure body 82 of a specific size with a locking notch 81 opened. For example, the locking structure body 82 is arranged behind the inclined support surface 72. The locking notch 81 opened by it is connected to the edge of the support surface 72.

[0154] Among them, the locking notch 81 can have a shape adapted to the cross-section of the supporting leg (for example, a substantially equivalent thickness and a width sufficient to accommodate the supporting leg), so that both the first surface and the second surface of the supporting leg inserted into the locking notch 81 can be in contact with the locking structure body, restricting the rotation of the supporting leg and supporting the supporting leg.

[0155] In some embodiments, please continue to refer to Figure 20 , the tripod can also include an additionally provided latching structure 90.

[0156] Among them, the latching structure 90 is provided with a groove adapted to the supporting leg 30, so that a part of the supporting leg 30 rotated to the target angle is latched in the groove. Thus, the latching structure 90 can provide a suitable magnitude of resistance to restrict the rotation of the supporting leg 30, so that the supporting leg 30 of the tripod in the deployed state can maintain its original angle and will not rotate due to its own gravity. In this application, the term "adapted" is used to represent the corresponding mating relationship between two components, so that the two can be correctly assembled together to achieve the expected function.

[0157] Specifically, the latching structure 90 can include: a pair of oppositely arranged elastic latches 91. Grooves 92 are opened on the surfaces of the elastic latches 91 close to the supporting leg.

[0158] Among them, an "elastic latch" refers to a structural component whose whole or part of the main body has the ability of elastic deformation. They are respectively arranged on both sides of the support structure, and the groove 92 is adapted to the side surface of the supporting leg 30 and has a substantially equivalent inclination angle and width.

[0159] In the actual use process, when a user applies a force, the support leg 30 can squeeze the elastic buckle 91, causing it to deform and thus snap into the groove 92. At this time, even if the external force applied to the support leg 30 is removed, the support leg 30 can be locked in the groove 92 and will not rotate due to its own gravity. When folding and retracting is needed, the user can apply an additional force to the support leg 20 to deform the elastic buckle 91 and make it disengage from the groove 92.

[0160] Based on the tripod provided by the embodiments of the present application, the present application further provides a pan-tilt head. Please continue to refer to Figure 6 and Figure 7 , in addition to the above tripod 1, the pan-tilt head further includes an additional housing 2. The housing 2 is connected to the base of the tripod 1 and encloses a receiving space for accommodating the support leg 30 in the carrying state.

[0161] In some embodiments, as Figure 8 shown, the pan-tilt head may further include: a cleaning mechanism 40 fixed to the housing.

[0162] Among them, the cleaning mechanism 40 is arranged in the receiving space and also has a through hole located on the movement track of the support leg for the support leg 30 to pass through. In other words, during the process of the support leg 30 entering the receiving space, it will pass through the through hole of the cleaning mechanism 40. The edge of the through hole is also coated with the above-mentioned scraping member 20, and thus an interference fit is also formed between the through hole and the support leg 30. Such a design can achieve multiple scraping and cleaning of the support leg, effectively improving the scraping and cleaning effect.

[0163] Preferably, an additional fixing component can be provided at the end of the support leg to fix the support leg that enters and is received in the receiving space to the housing.

[0164] Specifically, the fixing component can be a fixing rib, a fixing groove and / or a magnetic component, which respectively realize the fixation between the support leg and the housing by means of abutment, locking and magnetic adsorption. Alternatively, other suitable fixing structures or fixing methods can also be selected to realize the fixation between the support leg and the housing, which is not limited herein.

[0165] Such an additional fixing component can provide additional support and fixing points in the length direction of the support leg, ensuring the fixing effect of the support leg, and thus effectively avoiding problems such as unnecessary shaking or swinging of the support leg during the carrying state, resulting in abnormal noises.

[0166] It should be noted that the above-mentioned pan-tilt can also be provided with various additional functional structures and functional modules according to actual needs to meet different design purposes and functional requirements. For example, structural components such as a horizontal level, a clamping assembly, or a connecting mechanism, or the support feet 20 are designed to be telescopic, or a friction surface or one or more control buttons are provided on the outer surface of the housing. Here, no specific limitations are made.

[0167] The above content is a further detailed description of the present application in combination with specific / preferred embodiments, and it cannot be determined that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
