Description
Technical Field
[0001] This utility model belongs to the field of automotive technology, specifically relating to a telescopic handle structure and a car-mounted coffee machine. Background Technology
[0002] Portable car coffee makers have become an important added-value feature in high-end cars, enhancing the driving experience and meeting users' needs for instant hot drinks while traveling. However, in actual use, these products exhibit significant inconvenience when moved for tasks such as transporting, cleaning, maintenance, or troubleshooting. The core issue lies in the numerous functional and experiential flaws in the handle design of existing car coffee makers.
[0003] Specifically, the handle structure of most mainstream products currently uses a design where a metal rod is rigidly fixed to the top of the machine. This structure has three key problems: First, the grip gap between the metal handle and the machine body is a fixed size, failing to consider individual differences in the size of different users' hands and fingers. This makes it difficult for some users with different hand shapes to comfortably insert and grip the handle, or even to maintain a stable grip, resulting in extremely poor adaptability. Second, the rigidity of the metal material itself means that when users lift the machine, the force on their hands is concentrated at the contact point between the metal rod and their palm and fingers. The touch is stiff and the pressure distribution is uneven. Long-term and frequent use can easily cause local pressure pain in the fingers, seriously affecting the comfort of the user experience and the ease of use of the product. Third, the protruding fixed shape of the metal handle lacks an effective storage and hiding design. It not only occupies extra space when not in use, but also disrupts the overall shape and visual harmony of the coffee machine, which contradicts the refined and integrated design concept pursued by high-end in-vehicle equipment, affecting the aesthetic performance of the product. The aforementioned design flaws in the handle structure not only reduce the ease of use and user experience of the car coffee machine, but also, to some extent, restrict the improvement of the product's market competitiveness. Utility Model Content
[0004] To address the aforementioned problems in the prior art, this utility model provides a telescopic handle structure and a vehicle-mounted coffee machine.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:
[0006] A telescopic handle structure includes a connecting seat, a lifting strap, and an elastic component. The connecting seat has a receiving cavity; the free end of the lifting strap extends into the receiving cavity; the elastic component is disposed in the receiving cavity and connected to the free end of the lifting strap.
[0007] The lifting band has a lifting state and a return state. In the lifting state, the elastic component is stretched outward by the lifting band, and the lifting band and the connecting seat form a ring structure. In the return state, the elastic component retracts to drive the free end of the lifting band to return to its original position, so that the lifting band fits against the surface of the connecting seat.
[0008] In some alternative embodiments, the telescopic handle structure includes two sets of the elastic components; the two free ends of the lifting strap extend into the receiving cavity respectively; and the two sets of elastic components are respectively connected to the two free ends of the lifting strap.
[0009] In some alternative embodiments, one end of the lifting strap is a fixed end, connected to the connecting seat; the other end of the lifting strap is a free end, connected to the elastic component.
[0010] In some alternative embodiments, the elastic component includes a tension spring, one end of which is connected to the connecting seat and the other end of which is connected to the free end of the lifting strap, for applying tension to the lifting strap.
[0011] In some alternative embodiments, the elastic component further includes a strap joint connected to the free end of the lifting strap, one end of the tension spring being connected to the connecting seat and the other end being connected to the strap joint;
[0012] When the lifting belt is pulled outward, the belt joint can abut against the connecting seat to restrict the movement distance of the free end of the lifting belt.
[0013] In some alternative embodiments, the connector is slidably mounted on the connector base and configured to slide along the direction of movement of the free end of the lifting belt.
[0014] In some alternative embodiments, the telescopic handle structure further includes an auxiliary handle disposed outside the connecting seat and connected to the lifting strap for lifting the lifting strap.
[0015] In some alternative embodiments, the auxiliary handle is configured as a pull ring, which is riveted to the lifting strap.
[0016] In some optional embodiments, the outer surface of the connector is provided with a hidden groove for receiving the lifting strap so that the lifting strap remains flush with the surface of the connector in the return state.
[0017] In another aspect, this utility model proposes a car coffee machine, including the aforementioned telescopic handle structure.
[0018] Based on the above technical solutions, the technical effects achieved by this utility model are as follows:
[0019] The telescopic handle structure provided by this utility model includes a connecting seat, a lifting strap, and an elastic component. The connecting seat has a receiving cavity; the free end of the lifting strap extends into the receiving cavity; the elastic component is disposed in the receiving cavity and connected to the free end of the lifting strap for applying tension to the lifting strap; the lifting strap has a lifting state and a returning state. In the lifting state, the lifting strap and the connecting seat form a ring structure; in the returning state, the elastic component drives the free end of the lifting strap so that the lifting strap fits against the surface of the connecting seat.
[0020] The telescopic handle structure provided by this utility model allows for a larger gap between the handle and the connecting seat when the lifting strap is grasped and lifted. This provides a sufficiently large gap to accommodate different hand shapes and offers a good grip. When the lifting strap is released, the elastic component pulls the free end of the strap, causing the portion of the strap not retracted into the receiving cavity to adhere to and remain flush with the surface of the connecting seat, reducing space occupation and achieving a concealed handle effect.

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0035] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0036] This utility model provides a telescopic handle structure, including a connecting seat 100, a lifting strap 200, and an elastic component 300. The connecting seat 100 has a receiving cavity 101. The free end of the lifting strap 200 extends into the receiving cavity 101. The elastic component 300 is disposed in the receiving cavity 101 and connected to the free end of the lifting strap 200. The lifting strap 200 has a lifting state and a return state. In the lifting state, the elastic component 300 is stretched outward by the lifting strap 200, and the lifting strap 200 and the connecting seat 100 form a ring structure. In the return state, the elastic component 300 retracts to drive the free end of the lifting strap 200 to return to its original position, so that the lifting strap 200 fits against the surface of the connecting seat 100.
[0037] The telescopic handle structure provided by this utility model allows for the following operation: When the lifting strap 200 is pulled up, the free end of the lifting strap 200 moves to increase the gap between the lifting strap 200 and the connecting seat 100, thus providing a sufficiently large gap to accommodate different hand shapes and offering a good feel. When the lifting strap 200 is released, the elastic component 300 can pull the free end of the lifting strap 200, causing the portion of the lifting strap 200 not retracted into the receiving cavity 101 to adhere tightly to the surface of the connecting seat 100 and remain flush with the surface of the connecting seat 100, reducing space occupation and achieving a concealed handle effect.
[0038] The following combination Figures 1-10 The structure and shape of the telescopic handle structure provided in this embodiment will be described in detail:
[0039] In some optional embodiments, the telescopic handle structure includes two sets of elastic components 300; the two free ends of the lifting strap 200 extend into the receiving cavity 101 respectively; the two sets of elastic components 300 are respectively connected to the two free ends of the lifting strap 200. Specifically, when lifting the lifting strap 200 in the returned state, it is only necessary to grasp the middle position of the visible part of the lifting strap 200 to maintain balance, avoiding the center of gravity from being off-center, which would cause greater resistance or tilting of the item when lifting it.
[0040] Specifically, the connector 100 is provided with two threading holes 104, such as... Figure 6 As shown, the two free ends of the lifting strap 200 extend into the receiving cavity 101 and are connected to the elastic component 300 after passing through two strap holes 104.
[0041] In some optional embodiments, one end of the lifting strap 200 is a fixed end connected to the connecting seat 100; the other end of the lifting strap 200 is a free end connected to the elastic component 300. When gripping the lifting strap 200, the gripping position should be near the free end of the visible portion of the lifting strap 200 to ensure that the gripping position is in the middle section of the lifting strap 200 in the lifting state, thereby maintaining balance and preventing tilting when lifting the item.
[0042] To ensure accurate gripping and prevent items from tilting when lifted, markings can be set at the gripping positions of the lifting strap 200, such as using different colors, covering with other materials like rubber, or setting different textures.
[0043] In some alternative embodiments, the elastic component 300 includes a tension spring 310, one end of which is connected to the connecting seat 100 and the other end of which is connected to the free end of the lifting strap 200, for applying tension to the lifting strap 200, such as... Figure 2 , Figure 3As shown. When the lifting strap 200 is pulled up, the tension spring 310 is stretched and elongated. When the lifting strap 200 is released, the tension spring 310 returns to its original position to drive one free end of the lifting strap 200. Specifically, multiple tension springs 310 can be provided in the elastic component 300 to obtain appropriate elastic force and ensure balanced force applied to the lifting strap 200. Two parallel tension springs 310 can be used, with the points where the two tension springs 310 connect to the lifting strap 200 symmetrical about the centerline of the lifting strap 200 along its own length direction.
[0044] In some alternative embodiments, the elastic component 300 further includes a connector 320 connected to the free end of the lifting strap 200, and one end of the tension spring 310 connected to the connecting seat 100 and the other end connected to the connector 320, such as... Figure 2 , Figure 3 As shown, when the lifting strap 200 is pulled outward, the strap connector 320 abuts against the connecting seat 100 to constrain the movement distance of the free end of the lifting strap 200, and transmits the weight of the lifted item to the lifting strap 200 through the strap connector 320. Furthermore, the strap connector 320 protects the lifting strap 200, preventing a reduction in the lifespan of the lifting strap 200 when the tension spring 310 is directly connected to it.
[0045] Specifically, the connector 320 is configured as a ring with a rectangular cross-section, a U-shaped bend, or a housing with one open end. The connector 320 has holes for connection with the hook of the tension spring 310, facilitating the installation of the tension spring 310. The free end of the lifting strap 200 is inserted into the connector 320 and connected to it via a rivet buckle 330. Figure 2 , Figure 4 As shown. Alternatively, the connector 320 can be connected to the lifting belt 200 by crimping.
[0046] In an optional embodiment, the tension spring 310 can be replaced with a clockwork spring. However, the clockwork spring occupies a large amount of height space, and the increase in elasticity increases with the length pulled out, resulting in a significant increase in resistance when lifting the lifting strap 200.
[0047] In some alternative embodiments, the connector 320 is slidably mounted on the connector 100 and configured to slide along the direction of movement of the free end of the lifting belt 200. Specifically, as Figure 4 As shown, the connecting seat 100 is provided with a guide rail 103, and the connector 320 is snapped into the guide rail 103 and slidably connected to the guide rail 103, thereby ensuring that the connector 320 moves back and forth stably, so that the lifting and returning process of the lifting belt 200 is smooth and stable.
[0048] In this embodiment, two parallel guide rails 103 are provided to improve the stability of the movement of the connector 320 and to avoid the single guide rail 103 from being blocked when the connector 320 is subjected to force and deflection.
[0049] In some optional embodiments, the telescopic handle structure further includes an auxiliary handle 400, which is disposed outside the connecting seat 100 and connected to the lifting strap 200. The auxiliary handle 400 is used to lift the lifting strap 200, preventing the lifting strap 200 from being difficult to lift when it is in contact with the outer surface of the connecting seat 100. That is, when lifting the lifting strap 200, first grasping the auxiliary handle 400 creates a gap between the lifting strap 200 and the surface of the connecting seat 100 to facilitate grasping the lifting strap 200, and then grasping the lifting strap 200 to lift it.
[0050] In some alternative embodiments, the auxiliary handle 400 is configured as a pull ring, which is riveted to the lifting strap 200, such as... Figure 2 , Figure 3 As shown. Specifically, the pull ring includes a belt buckle 411 and a handle ring 412. The belt buckle 411 can be made of metal or plastic. The belt buckle 411 is connected to the lifting strap 200, and the handle ring 412 is rotatably mounted on the belt buckle 411. The handle ring 412 is designed as a C-shaped ring structure and passes through openings on both sides of the belt buckle 411.
[0051] In some optional embodiments, the auxiliary handle 400 is configured as an auxiliary belt, with both ends connected to the lifting belt 200 to form a loop structure. The auxiliary belt is not pulled by the elastic component 300, preventing it from adhering to the surface of the connecting seat 100 and making it difficult to lift. Specifically, the length of the auxiliary belt is greater than the distance between the two points where the auxiliary belt connects to the lifting belt 200, creating a gap for easy gripping.
[0052] Optionally, the auxiliary belt can be configured such that one end is connected to the lifting belt 200, and the other end is a free end, which is thickened or has through holes to facilitate gripping.
[0053] In this embodiment, the lifting strap 200 and the auxiliary strap can be made of leather belt, woven belt, silicone belt, metal chain, etc., and the woven belt can be set as cotton woven belt, polyester belt, rattan woven belt, nylon woven belt, etc.
[0054] In some optional embodiments, the outer surface of the connecting seat 100 is provided with a hidden groove 102. The hidden groove 102 is used to accommodate the lifting strap 200 so that the lifting strap 200 remains flush with the surface of the connecting seat 100 in the returned state. Specifically, this prevents the upper surface of the lifting strap 200 from protruding from the upper surface of the connecting seat 100, thereby achieving a good concealing effect and reducing the space occupied by the handle structure. Similarly, the hidden groove 102 also ensures that the upper surface of the auxiliary handle 400 does not protrude from the upper surface of the connecting seat 100.
[0055] In this embodiment, the connecting base 100 includes a top cover 110, a middle frame 120, and a base 130, as follows: Figure 2 , Figure 3 As shown, the middle frame 120 is mounted to the base 130 with screws, and the top cover 110 is mounted to the middle frame 120 with screws. Specifically, the hidden groove 102 and the strap hole 104 are formed in the base 130, the middle frame 120 is provided with a guide rail 103, and the end of the tension spring 310 away from the strap connector 320 is connected to the hole on the middle frame 120 by its own hook.
[0056] Based on the telescopic handle structure provided in this embodiment, a vehicle-mounted coffee machine is proposed, including a coffee machine body 10 and the telescopic handle structure described in the above embodiment, such as... Figure 7 As shown, the telescopic handle structure is connected to the upper end of the coffee machine body 10. Specifically, the connecting seat 100 is connected to the coffee machine body 10.
[0057] In a more preferred embodiment, the position of the lifting strap 200 can be arranged according to the center of gravity of the coffee machine body 10, such as... Figure 8 , Figure 9 As shown, this ensures that the coffee machine body 10 does not tilt when lifted by the lifting strap 200, thus making the process of lifting the coffee machine body 10 from the armrest box 20 smooth and stable, and preventing the coffee machine body 10 from tilting while suspended in the air, as... Figure 10 As shown.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
