Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a vehicle-mounted water cup holder and a vehicle. Background Technology

[0002] With the popularization of new energy vehicles, people have put forward higher requirements for them. They not only require new energy vehicles to provide a comfortable riding environment, but also to provide some conveniences needed for life. Since people often need to drink water or beverages while riding, the use of car cup holders for placing water cups in car interiors is becoming more and more widespread.

[0003] Existing car cup holders typically have a soft plastic coaster at the bottom of the cup holder. This coaster increases friction between the cup and the bottom of the cup, improving the stability of the cup within the holder. Furthermore, if the beverage spills, the coaster can be removed from the cup holder for cleaning, making cleaning the car cup holder simpler, more convenient, and easier.

[0004] However, in actual use, when the beverage in the cup is accidentally spilled, a small amount of beverage still flows into the bottom of the cup holder through the edge of the coaster. If it is not cleaned thoroughly in time, the sugar in the beverage will solidify at the bottom of the cup holder and attract a lot of dust, making it difficult to clean the inside of the cup holder and reducing the user experience. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the prior art by providing a car water cup holder and a car, further simplifying and making the cleaning of the car water cup holder simple and convenient, and improving the user experience.

[0006] This utility model proposes a car cup holder and a car, including a holder body and a coaster. The holder body has a cup-holding cavity with a top opening for holding a cup. The coaster is detachably installed in the cup-holding cavity. The coaster installed in the cup-holding cavity covers at least the bottom wall and side wall of the cup-holding cavity. When the cup is placed in the cup-holding cavity, the coaster is located between the cup and the cup-holding cavity.

[0007] Furthermore, the coaster includes an integrally connected cup-holding body and an extension body, as well as a limiting cavity formed in the cup-holding body and the extension body. The cup-holding body covers the bottom wall and side wall of the cup-holding cavity, and the extension body covers the top wall of the cup-holding cavity. When the water cup is placed in the cup-holding cavity, the limiting cavity is located outside the water cup and limits the water cup.

[0008] Furthermore, the top of the support body is provided with a first limiting groove, which communicates with the top opening of the cup placement cavity, and the extension body is inserted into the first limiting groove.

[0009] Furthermore, the inner wall of the cup-holding cavity is provided with a second limiting groove, the second limiting groove extends vertically along the inner wall of the cup-holding cavity and its top communicates with the first limiting groove, and the outer wall of the cup-holding body is provided with a first cup pad limiting block, the first cup pad limiting block extends vertically along the outer wall of the cup-holding body and is inserted into the second limiting groove.

[0010] Furthermore, the inner wall of the limiting cavity is provided with a cup limiting protrusion, which limits the water cup placed in the cup cavity.

[0011] Furthermore, the cup limiting protrusions are multiple protrusions arranged circumferentially on the inner wall of the limiting cavity, and the multiple cup limiting protrusions simultaneously limit the water cup placed in the cup cavity.

[0012] Furthermore, one end of the cup limiting protrusion extends inside the cup body, and the other end penetrates the inner wall of the cup body. The end face of the cup limiting protrusion extending inside the cup body is an arc-shaped surface. The first coaster limiting block is integrally connected to the end of the cup limiting protrusion that penetrates the inner wall of the cup body.

[0013] Furthermore, the top of the bracket body has a third limiting groove extending vertically, the third limiting groove being located outside the first limiting groove and the top of the first limiting groove communicating with the outside. The extension body is provided with a second coaster limiting block, the second coaster limiting block extending vertically on the extension body and engaging with the third limiting groove.

[0014] Furthermore, the lateral width of the second coaster limiting block is greater than the lateral width of the third limiting groove.

[0015] This utility model also proposes a car, including the above-mentioned car water cup holder.

[0016] The vehicle-mounted water cup holder and automobile proposed in this utility model have the following beneficial effects: (1) When the coaster of this car cup holder is installed in the cup cavity, it covers at least the bottom and side walls of the cup cavity. In case of accidental spillage of beverage in the cup, the coaster covers a large area of ​​the inner wall of the cup cavity, reducing the risk of beverage entering the cup cavity through the edge of the coaster. This allows the spilled beverage to remain in the coaster as much as possible. The coaster can be detached from the cup cavity for cleaning, making the cleaning operation of the car cup holder simple, convenient and easy to implement, thus improving the user experience. (2) The top of the bracket body of this car water cup holder is provided with a first limiting groove. When the cup body is inserted into the cup cavity through the top opening of the cup cavity, the extension body is inserted into the first limiting groove. Thus, through the cooperation between the cup body and the cup cavity, and the cooperation between the extension body and the first limiting groove, the stability of the cup pad installed on the bracket body is stronger, thereby improving the stability of the water cup placed in the car water cup holder. (3) The inner wall of the cup-holding cavity of this car water cup holder is provided with a second limiting groove, and the outer wall of the cup-holding body is provided with a first cup pad limiting block. The second limiting groove extends vertically along the inner wall of the cup-holding cavity and its top is connected to the first limiting groove. The first cup pad limiting block extends vertically along the outer wall of the cup-holding body. Thus, through the cooperation of the first cup pad limiting block and the second limiting groove, the stability of the cup pad installed on the holder body is stronger, thereby improving the stability of the water cup placed in the car water cup holder. (4) The inner wall of the cup holder of this car cup holder is provided with a cup limiting protrusion. When the cup is placed in the limiting cavity, the cup limiting protrusion on the inner wall of the cup holder abuts against the outer wall of the cup, thereby limiting the cup installed in the limiting cavity through the cup limiting protrusion, improving the stability of the cup in the car cup holder, preventing the cup from shaking in the car cup holder, reducing the risk of the beverage spilling out of the cup, and further improving the user experience. (5) When the cup limiting protrusion of this car cup holder is set on the inner wall of the cup holder, one end extends inside the cup holder and the other end penetrates the inner wall of the cup holder, so that the end of the cup limiting protrusion extending inside the cup holder abuts against the outer wall of the cup placed in the limiting cavity to limit the cup; the end of the cup limiting protrusion penetrating the inner wall of the cup holder is integrally connected with the first cup pad limiting block, thereby enhancing the stability of the overall structure of the cup pad. (6) The end face of the cup limiting protrusion extending inside the cup body of this car cup holder is set as an arc surface so that the cup can be placed in the limiting cavity, thereby making the use of this car cup holder more convenient and further improving the user experience; (7) The top of the bracket body of this vehicle water cup holder is provided with a third limiting groove, and the extension body is provided with a second cup pad limiting block. The third limiting groove extends vertically at the top of the bracket body, and the second cup pad limiting block extends vertically on the extension body. Thus, the stability of the cup pad on the bracket body is further enhanced by the cooperation between the second cup pad limiting block and the third limiting groove. (8) The lateral width of the second cup pad limiting block of this car cup holder is greater than the lateral width of the third limiting groove. This makes the lateral width range of the second cup pad limiting block exceed the lateral width range of the third limiting groove when the second cup pad limiting block is inserted into the third limiting groove. This allows the user to remove the cup pad from the main body of the holder through the second cup pad limiting block, making the removal of the cup pad from the main body of the holder simpler, more convenient and easier to implement, and further improving the user experience.

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-5This utility model discloses a car cup holder, comprising a holder body 1 and a cup pad 2. The holder body 1 has a cup-holding cavity 11 with a top opening for holding a cup. The cup pad 2 is detachably installed in the cup-holding cavity 11. In actual use, the cup pad 2 can be placed in the cup-holding cavity 11 through the top opening, so that when the cup is placed in the cup-holding cavity 11, the cup pad 2 is located between the cup and the cup-holding cavity 11, thereby limiting the position of the cup and improving the stability of the cup when placed in the car cup holder.

[0022] It is foreseeable that in this application, the coaster 2 can be made of soft plastic material, so that when the water cup is placed in the cup cavity 11, the coaster 2 can fit the water cup better and can also buffer the vibration generated by the car operation to a certain extent, further improving the stability of the water cup placed in the car water cup holder.

[0023] Existing car cup holders typically have a cup pad 2 placed at the bottom of the cup cavity 11, with the cup pressed against the cup pad 2 when placed in the cup cavity 11. In this application, the cup pad 2 installed in the cup cavity 11 covers at least the bottom and side walls of the cup cavity 11. Therefore, when the cup is placed in the cup cavity 11, the cup pad 2, made of soft plastic material, surrounds the bottom and outer periphery of the cup, which can better limit the cup's position and also buffer external vibrations to a certain extent, thereby improving the stability of the cup when placed in the car cup holder.

[0024] Furthermore, in existing car cup holders, when the coaster 2 is placed in the cup-holding cavity 11 of the holder body 1, it only covers the bottom wall of the cup-holding cavity 11. When the beverage in the cup is accidentally spilled, a small amount of beverage still flows into the bottom of the cup-holding cavity 11 through the edge of the coaster 2. If it is not cleaned thoroughly in time, the sugar in the beverage will solidify at the bottom of the limiting cavity 21 of the car cup holder and be contaminated with a lot of dust, making it difficult to clean the inside of the car cup holder and reducing the user experience.

[0025] In this application, the coaster 2 installed in the cup cavity 11 covers at least the bottom and side walls of the cup cavity 11. In the event of accidental spillage of beverage in the cup, the coaster 2 covers a large area of ​​the inner wall of the cup cavity 11, reducing the risk of beverage entering the cup cavity 11 through the edge of the coaster 2. This allows the spilled beverage to remain in the coaster 2 as much as possible, thereby effectively preventing the spilled liquid from remaining in the support body 1 and maintaining the cleanliness of the support body 1.

[0026] Since the coaster 2 is detachably installed in the cup cavity 11, when cleaning, you only need to remove the coaster 2 from the bracket body 1 for cleaning and then reinstall it back into the bracket body 1. This makes the cleaning operation of the car cup holder simpler, more convenient and easier to implement, and improves the user experience.

[0027] In this embodiment, the coaster 2 includes a cup body 22, an extension body 23, and a limiting cavity 21. The cup body 22 and the extension body 23 are integrally connected, and the extension body 23 is located at the top of the cup body 22. The limiting cavity 21 is formed in the cup body 22 and the extension body 23, and the top of the limiting cavity 21 is open.

[0028] When the coaster 2 is installed in the cup cavity 11, the cup body 22 is inserted into the cup cavity 11 through the top opening of the cup cavity 11. The extension body 23 located at the top of the cup body 22 extends horizontally at the top of the support body 1, so that the cup body 22 covers the bottom wall and side wall of the cup cavity 11, and the extension body 23 covers the top wall of the cup cavity 11.

[0029] When the water cup is placed in the cup cavity 11, the limiting cavity 21 formed in the cup body 22 and the extension body 23 surrounds the outside of the water cup, limiting the water cup. This further reduces the risk of beverage entering the cup cavity 11 through the edge of the coaster 2 when the beverage in the water cup is accidentally spilled. This makes the cleaning operation of the car water cup holder simpler, more convenient and easier to implement, and improves the user experience.

[0030] In this embodiment, a first limiting groove 12 is provided on the top of the bracket body 1. When the cup body 22 is inserted into the cup cavity 11 through the top opening of the cup cavity 11, the extension body 23 is inserted into the first limiting groove 12. Thus, through the cooperation between the cup body 22 and the cup cavity 11, and the cooperation between the extension body 23 and the first limiting groove 12, the stability of the coaster 2 installed on the bracket body 1 is strengthened, thereby improving the stability of the water cup placed in the car water cup holder.

[0031] It is foreseeable that in this application, the cross-sectional area of ​​the first limiting groove 12 and the extension body 23 is greater than the cross-sectional area of ​​the cup cavity 11, that is, the extension range of the extension body 23 exceeds the range of the cup cavity 11. Therefore, when the beverage in the cup is accidentally spilled, even if a small amount of beverage flows into the support body 1 through the edge of the extension body 23, it will only remain in the first limiting groove 12.

[0032] The first limiting groove 12 is located at the top of the bracket body 1. Compared with beverage residue in the cup cavity 11, beverage residue in the first limiting groove 12 is easier to clean, making the cleaning operation of the car water cup holder simpler, more convenient and easier to implement, thus improving the user experience.

[0033] In this embodiment, a second limiting groove 111 is provided on the inner wall of the cup cavity 11, and a first cup pad limiting block 221 is provided on the outer wall of the cup body 22. The second limiting groove 111 extends vertically on the inner wall of the cup cavity 11 and its top is connected to the first limiting groove 12. The first cup pad limiting block 221 extends vertically on the outer wall of the cup body 22.

[0034] When the cup holder 22 is inserted into the cup holder 11 through the top opening of the cup holder 11, the first cup pad limiting block 221 is inserted into the second limiting groove 111, and the extension body 23 is inserted into the first limiting groove 12. Thus, through the cooperation between the cup holder 22 and the cup holder 11, the cooperation between the first cup pad limiting block 221 and the second limiting groove 111, and the cooperation between the extension body 23 and the first limiting groove 12, the stability of the cup pad 2 installed on the bracket body 1 is strengthened, thereby improving the stability of the water cup placed in the car water cup holder.

[0035] In this application, the second limiting groove 111 extends vertically along the inner wall of the cup cavity 11, and the first cup pad limiting block 221 extends vertically along the outer wall of the cup body 22. Therefore, the insertion and cooperation between the first cup pad limiting block 221 and the second limiting groove 111 not only enhances the installation stability of the cup pad 2 on the bracket body 1, but also guides the installation of the cup pad 2 on the bracket body 1, making the installation of the cup pad 2 on the bracket body 1 simpler, more convenient, and easier to implement, further improving the user experience.

[0036] In this application, the depth of the second limiting groove 111 extending vertically is less than the depth of the cup cavity 11. The height of the first cup pad limiting block 221 extending vertically is less than the height of the cup body 22, so that when the cup body 22 is inserted into the bottom of the cup cavity 11, the bottom of the first cup pad limiting block 221 just abuts against the bottom wall of the second limiting groove 111.

[0037] Furthermore, in this embodiment, multiple second limiting grooves 111 are arranged circumferentially along the inner wall of the cup-holding cavity 11, and multiple first cup pad limiting blocks 221 are arranged circumferentially along the outer wall of the cup-holding body 22. When the cup-holding body 22 is inserted into the cup-holding cavity 11 through the top opening of the cup-holding cavity 11, the multiple first cup pad limiting blocks 221 are respectively inserted into the multiple second limiting grooves 111, thereby further enhancing the stability of the cup pad 2 installed on the support body 1 through the cooperation of the multiple first cup pad limiting blocks 221 and the multiple second limiting grooves 111.

[0038] In this embodiment, the inner wall of the limiting cavity 21 is provided with a cup limiting protrusion 222. When the cup is placed in the cup placement cavity 11, the cup limiting protrusion 222 on the inner wall of the limiting cavity 21 abuts against the outer wall of the cup, thereby limiting the cup installed in the cup placement cavity 11 by the cup limiting protrusion 222, improving the stability of the cup in the car cup holder, preventing the cup from shaking in the car cup holder, reducing the risk of the beverage spilling out of the cup, and further improving the user experience.

[0039] Furthermore, in this embodiment, the cup-limiting protrusions 222 are multiple protrusions arranged circumferentially on the inner wall of the limiting cavity 21. When the cup is placed in the cup-holding cavity 11, the multiple cup-limiting protrusions 222 abut against the outer wall of the cup at different positions along the circumferential direction, thereby better limiting the cup and further improving the stability of the cup when placed in the vehicle cup holder.

[0040] Specifically, in this embodiment, when the cup limiting protrusion 222 is disposed on the inner wall of the limiting cavity 21, one end extends inside the cup body 22 and the other end penetrates through the inner wall of the cup body 22, so that the end of the cup limiting protrusion 222 extending inside the cup body 22 abuts against the outer wall of the cup placed in the cup cavity 11 to limit the cup; the end of the cup limiting protrusion 222 penetrating through the inner wall of the cup body 22 is integrally connected with the first coaster limiting block 221, thereby enhancing the stability of the overall structure of the coaster 2.

[0041] In this application, the water cup is positioned by the end of the cup limiting protrusion 222 extending inside the cup body 22 abutting against the outer wall of the water cup placed in the cup cavity 11. Therefore, the end face of the end of the cup limiting protrusion 222 extending inside the cup body 22 is set as an arc-shaped surface 2221 to facilitate the placement of the water cup in the cup cavity 11, thereby making the use of this car water cup holder more convenient and further improving the user experience.

[0042] In this embodiment, a third limiting groove 13 is provided on the top of the bracket body 1, and a second cup pad limiting block 231 is provided on the extension body 23. The third limiting groove 13 extends vertically on the top of the bracket body 1, and the second cup pad limiting block 231 extends vertically on the extension body 23.

[0043] Since the third limiting groove 13 is located outside the first limiting groove 12 and its top connects the first limiting groove 12 to the outside, when the extension body 23 is inserted into the first limiting groove 12, the second coaster limiting block 231 is inserted into the third limiting groove 13. Thus, through the cooperation of the second coaster limiting block 231 and the third limiting groove 13, the stability of the coaster 2 installed on the bracket body 1 is further enhanced.

[0044] Furthermore, in this embodiment, the third limiting groove 13 consists of two separate grooves located on both sides of the first limiting groove 12, and the second coaster limiting block 231 consists of two separate grooves located on both sides of the extension body 23. Therefore, when the extension body 23 is inserted into the first limiting groove 12, the two second coaster limiting blocks 231 are respectively inserted into the two third limiting grooves 13. Thus, by having the two second coaster limiting blocks 231 cooperate with the two third limiting grooves 13 respectively, the stability of the coaster 2 installed on the bracket body 1 is further enhanced.

[0045] Furthermore, in this embodiment, the lateral width of the second coaster limiting block 231 is greater than the lateral width of the third limiting groove 13. This means that when the second coaster limiting block 231 is inserted into the third limiting groove 13, the lateral width range of the second coaster limiting block 231 exceeds the lateral width range of the third limiting groove 13. This allows the user to remove the coaster 2 from the support body through the second coaster limiting block 231, making the removal of the coaster 2 from the support body simpler, more convenient, and easier to implement, further improving the user experience.

[0046] Specifically, in actual implementation, the first coaster limiting block 221 and the cup limiting protrusion 222 can be made of the same soft plastic material as the cup body 22, so that the cup limiting protrusion 222 protects the cup when it abuts against the outer wall of the cup; the second coaster limiting block 231 can be made of the same soft plastic material as the outer extension 23 to ensure the consistency of the overall material of the coaster 2, or it can be made of hard plastic material, so that the two second coaster limiting blocks 231 cooperate with the two third limiting grooves 13 respectively to further enhance the stability of the coaster 2 installed on the bracket body 1.

[0047] This utility model embodiment also provides a car, including the above-mentioned car water cup holder.
