Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] Car video surveillance equipment generally uses a push-pull storage flash memory card holder, and then matches it with a TF card to record videos and other important information. The TF card holders currently used in the market are all industry-wide card holders. This universal TF card holder is for all electronic products, and there is no special card holder designed for the vehicle environment that requires high vibration resistance. Therefore, the TF card holders we currently use are also the industry-wide push-pull TF card holders. This TF card holder has a fatal disadvantage: the vibration resistance of the TF card and the TF card holder after assembly is poor, and the TF card often drops out and the video cannot be stored.

[0029] In order to alleviate the above technical problems, the utility model proposes a new card holder structure and a vehicle-mounted video surveillance device. The card holder structure proposed in the utility model can be applicable to terminal cards 101 such as TF cards, SD cards, SIM cards, etc. The terminal card 101 in the utility model can be any card on the market. The card holder structure includes a circuit board 1, a card holder body 2 and an elastic device 3. The terminal card 101 is installed in the accommodating space 20 formed between the card holder body 2 and the circuit board 1. By setting a protruding structure 324 on the elastic device 3, and making the protruding structure 324 abut the terminal card 101 to the card holder body 2, the possibility of displacement of the terminal card 101 is reduced, so that the terminal card 101 and the circuit board 1 are always kept conductive, and the terminal card 101 is prevented from being disconnected.

[0030] The card holder structure provided in the embodiment of the utility model is now described.

[0031] See also Figure 1 and Figure 2 The card seat structure includes a circuit board 1, a card seat body 2 and a spring 3.

[0032] The circuit board 1 has a circuit structure inside, and the circuit board 1 is a plate-shaped structure and can be installed in a portion of a host housing.

[0033] The card holder body 2 is arranged on the circuit board 1, and a receiving space 20 is formed between the card holder body 2 and the circuit board 1, and the receiving space 20 is used to receive the terminal card 101. Since the terminal card 101 needs to be inserted into the receiving space 20, the receiving space 20 has at least one opening on one side, and the opening is the entrance of the receiving space 20, and the terminal card 101 enters the receiving space 20 from the entrance. Accordingly, the card holder body 2 is in the shape of a box cover, and the peripheral side of the card holder body 2 in the shape of a box cover has at least one opening, which is the opening of the receiving space 20, and the terminal card 101 can enter the receiving space 20 through the opening.

[0034] The elastic device 3 is arranged at the entrance of the accommodating space 20. The elastic device 3 includes a fixing portion 31 and an elastic pin 32 which are connected to each other. The fixing portion 31 is used to be fixed on the circuit board 1 so that the elastic device 3 is fixedly connected to the circuit board 1. The elastic pin 32 has a certain elasticity and can be deformed under the action of external force. The elastic pin 32 includes an inclined section 321 and a tail section 322. The fixing portion 31, the inclined section 321 and the tail section 322 are connected in sequence. The inclined section 321 extends from the fixing portion 31 toward the card holder body 2. The inclined section 321 is arranged at an angle with the circuit board 1, and the larger surface of the circuit board 1 is taken as the horizontal plane. The inclined section 321 can be understood as being arranged inclined relative to the circuit board 1. The tail section 322 extends from the end of the inclined section 321 away from the fixed portion 31 toward the circuit board 1. If the surface of the circuit board 1 is taken as a horizontal plane, the connection between the inclined section 321 and the tail section 322 is the position where the distance between the spring pin 32 and the horizontal plane is the largest, that is, a corner 323 protruding toward the card holder body 2 is formed at the connection between the inclined section 321 and the tail section 322, that is, the distance between the corner 323 and the top side of the box-shaped card holder body 2 is the shortest. A protruding structure 324 is provided at the corner 323, and the protruding structure 324 is used to abut against the terminal card 101.

[0035] Specifically, see Figure 3 and Figure 4 Before the terminal card 101 is inserted into the card holder body 2, one side of the terminal card 101 is first placed at the entrance of the accommodation space 20. When the terminal card 101 is inserted, the inclined section 321 of the elastic device 3 guides the terminal card 101, making it easier for the terminal card 101 to enter the accommodation space 20. The terminal card 101 can be inserted without being completely aligned with the entrance of the accommodation space 20. After being guided by the inclined section 321, the terminal card 101 enters the accommodation space 20, and the protruding structure 324 of the elastic device 3 abuts against the side of the terminal card 101 facing the circuit board 1, and the side of the terminal card 101 facing away from the circuit board 1 abuts against the top side of the card holder body 2. Under the elastic force of the spring pin 32, the terminal card 101 is abutted against the top side of the card holder body 2, ensuring that the terminal card 101 and the card holder body 2 can cooperate well and eliminate the assembly gap. In the daily vehicle-mounted vibration environment, the terminal card 101 will not have relative displacement with the card holder body 2, thereby ensuring that the gold finger area of ​​the terminal card 101 is in contact with the metal spring 21 inside the card holder body 2, and the metal spring 21 is connected and conductive with the circuit board 1, thereby achieving high shock resistance of the card holder structure, the terminal card 101 will not be disconnected, and important information such as video can be stored in real time.

[0036] Thus, the setting of the elastic device 3 can not only guide the insertion of the terminal card 101, but also limit the terminal card 101 to prevent it from shifting in a vibration environment, thereby ensuring real-time conduction between the terminal card 101 and the circuit board 1.

[0037] It should be noted that the card holder body 2 can be a conventional structure. The utility model can reduce the movement of the terminal card 101 in the card holder body 2 by only adding the elastic device 3, so that the terminal card 101 and the card holder body 2 are more closely matched, ensuring that the terminal card 101 will not move relative to the card holder body 2 due to vibration, thereby ensuring that the terminal card 101 will not be disconnected. The elastic device 3 provided in this embodiment does not need to change the card holder structure, and the cost of improvement is low.

[0038] The card holder structure in the above embodiment includes a circuit board 1, a card holder body 2 and an elastic device 3. The card holder body 2 is arranged on the circuit board 1. The accommodation space 20 formed between the card holder body 2 and the circuit board 1 is used to place the terminal card 101. The elastic device 3 includes a fixing portion 31, an inclined section 321 and a tail section 322 connected in sequence, and the elastic device 3 is arranged at the entrance of the accommodation space 20. When the terminal card 101 is inserted from the entrance of the accommodation space 20, the inclined section 321 can guide the terminal card 101. A corner 323 is formed between the inclined section 321 and the tail section 322. A protruding structure 324 is arranged on the corner 323. The protruding structure 324 abuts against the terminal card 101, and can abut and fix the terminal card 101, so that the terminal card 101 is close to the card holder body 2, thereby reducing the influence of vibration on the position of the terminal card 101, and thereby making the terminal card 101 always conductive with the circuit board 1.

[0039] In some embodiments of the present invention, please refer to Figure 2 The protruding structure 324 is in point contact or line contact with the terminal card 101. The protruding structure 324 is protruding from the surface of the spring pin 32. Compared with the corner 323 of the spring pin 32 directly contacting the terminal card 101, the protruding structure 324 can reduce the contact area between the spring pin 32 and the terminal card 101, thereby preventing the terminal card 101 from being scratched by the spring pin 32.

[0040] In some embodiments, the protrusion structure 324 is in point contact with the terminal card 101, so that the contact area between the spring pin 32 and the terminal card 101 is point-shaped, and the contact area is relatively small, which reduces the wear on the surface of the terminal card 101. In this embodiment, the surface of the protrusion structure 324 can be in a hemispherical shape, etc., and is in point contact with the plane of the terminal card 101.

[0041] In some embodiments, the protruding structure 324 is in line contact with the terminal card 101, so that the contact area between the spring pin 32 and the terminal card 101 is linear, and the contact area is relatively small, which reduces the wear on the surface of the terminal card 101. In this embodiment, the surface of the protruding structure 324 can be in a shape such as a semi-cylinder, and is in line contact with the plane of the terminal card 101.

[0042] In some embodiments, the protrusion structure 324 contacts the gold finger of the terminal card 101, or the protrusion structure 324 contacts the insulating part of the terminal card 101. The main purpose of the spring pin 32 is to abut the terminal card 101, and whether it contacts the gold finger of the terminal card 101 will not affect the abutment of the spring pin 32 to the terminal card 101.

[0043] In some embodiments of the utility model, the inclined section 321 is in the shape of an elongated strip, and the center line of the inclined section 321 can be straight, curved, or bent. When the center line of the inclined section 321 is straight, the structure of the spring pin 32 is relatively simple; when the center line of the inclined section 321 is curved or bent, the strength of the inclined section 321 is higher, which can improve the elastic force and structural strength of the spring pin 32.

[0044] In some embodiments of the present invention, the tail section 322 is in a block-shaped, sheet-shaped or other structure, and the specific shape of the tail section 322 is not limited herein.

[0045] In some embodiments of the present invention, the inclined section 321 and the tail section 322 are connected at an angle, so that the junction of the two forms a corner 323, and the angle between the inclined section 321 and the tail section 322 is an obtuse angle, which facilitates the processing of the elastic needle 32 and prevents the occurrence of a stress concentration point at the connection between the inclined section 321 and the tail section 322.

[0046] Optionally, the surface of the corner 323 may be rounded to make the surface of the spring pin 32 smoother, thereby avoiding scratching the terminal card 101 .

[0047] In some embodiments, the elastic device 3 can be made of insulating materials such as plastic and resin, or metals such as nickel silver. The material of the elastic device 3 is not limited here, and the material of the elastic device 3 does not affect the contact of the elastic pin 32 with the terminal card 101.

[0048] In some embodiments of the present invention, please refer to Figure 2 , there are two spring pins 32, and the two spring pins 32 are respectively arranged on opposite sides of the fixing part 31. By setting the two spring pins 32, there can be two contact positions arranged at intervals between the elastic device 3 and the terminal card 101, so that the elastic device 3 can be more stably abutted against the terminal card 101, and the terminal card 101 can be prevented from shaking when the card seat structure vibrates. The plug-in direction of the terminal card 101 is the first direction, and the length direction of the fixing part 31 is the second direction. The first direction and the second direction are perpendicular to each other. The two spring pins 32 can be arranged on opposite sides of the fixing part 31 in the second direction, so that the position of the terminal card 101 can be more stable.

[0049] In other embodiments, the number of the elastic pins 32 may also be three, four, etc., and the plurality of elastic pins 32 may be distributed in sequence and at intervals along one side of the fixing portion 31 .

[0050] In some embodiments of the present invention, please refer to Figure 2 The inclined section 321 is provided with hollow holes 3210 arranged along its length direction. The hollow holes 3210 are in a long strip shape and are distributed along the length direction of the inclined section 321. Therefore, the weight of the spring needle 32 can be reduced, raw materials can be saved, and the strength of the spring needle 32 can be reduced, making the spring needle 32 more easily deformed.

[0051] In other embodiments, the hollow hole 3210 may include a plurality of holes arranged at intervals. Alternatively, the hollow hole 3210 is in a pattern shape.

[0052] In some embodiments of the present invention, please refer to Figure 3 and Figure 4 The fixing portion 31 is provided with a fixing pin 33, and the circuit board 1 is correspondingly provided with a pin hole 10 for inserting the fixing pin 33.

The fixing pin 33 is a protruding portion formed by the fixing portion 31 extending toward the circuit board 1. The fixing pin 33 is generally perpendicular to the fixing portion 31 so that it can be inserted into the pin hole 10 of the circuit board 1.

[0053] Optionally, the cross section of the fixing pin 33 is a flat structure, that is, the fixing pin 33 is a long sheet structure, and the pin hole 10 is also a square hole. By setting the fixing pin 33 as a sheet structure, the processing of the fixing pin 33 is convenient, and the fixing part 31 and the fixing pin 33 can be integrally formed by sheet metal forming or the like.

[0054] Optionally, the fixing pin 33, the fixing portion 31 and the spring pin 32 are integrally formed, such as by sheet metal forming.

[0055] Optionally, the number of the fixing pins 33 is two, which are respectively arranged on opposite sides of the fixing portion 31, so that it can be fixed more stably on the circuit board 1. The number of the pin holes 10 on the circuit board 1 is also two, and the shape of the cross section is the same as that of the fixing pins 33. In other embodiments, the number of the fixing pins 33 can also be three, four, etc.

[0056] In some embodiments, when installing the elastic device 3, the fixing pin 33 of the elastic device 3 is first inserted into the pin hole 10 of the circuit board 1, and then the fixing pin 33 is fixed to the circuit board 1 by welding or other means, so that the entire elastic device 3 is fixed to the circuit board 1.

[0057] In some embodiments, the fixing portion 31 is provided with through holes 310, and the number, shape and arrangement of the through holes 310 are not limited. The provision of the through holes 310 can reduce the weight of the fixing portion 31, reduce the raw materials required for the fixing portion 31, and reduce the processing cost of the elastic device 3.

[0058] In some embodiments of the present invention, please refer to Figure 3 and Figure 4 , a metal spring 21 fixed to the circuit board 1 is arranged inside the accommodation space 20, the metal spring 21 is electrically connected to the circuit board 1, and the metal spring 21 abuts against the gold finger of the terminal card 101.

The metal spring 21 is located inside the accommodation space 20, and at least part of the elastic device 3 is located outside the accommodation space 20. Therefore, in the plug-in direction of the terminal card 101, the metal spring 21 and the elastic device 3 abut against the terminal card 101, respectively, which can reduce the influence of the vibration environment on the terminal card 101.

[0059] Optionally, the metal spring 21 is made of metal and is used to conduct the terminal card 101 and the circuit board 1 to achieve functions such as video storage.

[0063] Optionally, the shape of the suction cup portion 311 may be a semicircular, circular or other structure, which is similar to the shape of the suction cup, so as to facilitate suction by the suction cup.

[0064] In some embodiments of the present invention, please refer to Figure 2 At least one side of the suction cup portion 311 is provided with a stopper portion 312 for positioning the suction cup. The stopper portion 312 can be understood as the suction cup portion 311 extending in the thickness direction thereof. The stopper portion 312 can be provided at the edge of the suction cup portion 311 or in the middle of the suction cup portion 311. When the suction cup is adsorbed on the suction cup portion 311, the stopper portion 312 can limit the edge of the suction cup to prevent the suction cup and the suction cup portion 311 from relative slipping. At the same time, the setting of the stopper portion 312 can also enhance the overall strength of the fixing portion 31 and prevent the edge of the suction cup portion 311 from being deformed.
